After the trials, the Ro-Railer vehicle was put into service at but the service was not continued on the Nickey Line.

The internal layout was typical of German tanks. Forward was an open crew compartment, with the driver and radio-operator seated at the front on either side of the gearbox. Behind them the turret floor was surrounded by panels forming a continuous level surface. This helped the loader to retrieve the ammunition, which was mostly stowed above the tracks.

When the animal sits at rest on a level surface, the tip of the longest rear toe reaches to directly below the tympanum. The ventral skin is smooth and white, except for dark mottling on the throat. The mottling inspired the specific epithet fuscigula: Latin for "dusky throated". In some specimens, the mottling extends to the belly.

Long in 1820 Historic photo of the High Plains in Haskell County, Kansas, showing a treeless semi-arid grassland and a buffalo wallow or circular depression in the level surface. (Photo by W.D. Johnson, 1897) Darton, N.H. 1920. Syracuse-Lakin folio, Kansas. United States Department of the Interior, U.S. Geological Survey, Folios of the Geologic Atlas, No. 212, 10 pp.

Static equilibrium was understood well before the invention of classical mechanics. Objects that are at rest have zero net force acting on them. The simplest case of static equilibrium occurs when two forces are equal in magnitude but opposite in direction. For example, an object on a level surface is pulled (attracted) downward toward the center of the Earth by the force of gravity.

Blueboard also has square edges rather than the tapered-edge drywall boards. The tapered drywall boards are used to countersink the tape in taped jointing whereas the tape in veneer plastering is buried beneath a level surface. One coat veneer plaster over dry board is an intermediate style step between full multi-coat "wet" plaster and the limited joint-treatment-only given "dry" wall.

Amontons is a tiny lunar impact crater in the western half of the Mare Fecunditatis. It is a circular, cup-shaped formation that has been excavated out of the level surface by the impact, and is the same dark hue as the surrounding mare. When the sun is at a low angle, multiple ghost-craters are visible in the mare surface to the south-southeast and north of it.

Grass runouts are always a last option, given an adjacent grassy area. An inline speedskater takes much time to stop and often has still fewer options in an emergency, often taking several hundred feet on a level surface to come to a stop at a full, controlled deceleration. Thus, a skater should be familiar with and proficient in stopping techniques before attempting difficult situations such as heavily travelled roads or hills.

The satellite crater Rosenberger D, which is about 50 kilometers in diameter, intrudes into the southern rim of Rosenberger. A number of smaller, worn impact craters lie along the remainder of the rim and inner wall.

The western plateau with an average elevation of above mean sea level merges into the plateau of the Surguja district of Chhattisgarh. The flat topped plateau, locally known as pats are characterized by level surface and accordance of their summit levels shows they are part of one large plateau. Examples include Netarhat Pat, Jamira Pat, Khamar Pat, Rudni Pat and others. The area is also referred to as Western Ranchi Plateau.

Diamond turning is a multi-stage process. Initial stages of machining are carried out using a series of CNC lathes of increasing accuracy. A diamond-tipped lathe tool is used in the final stages of the manufacturing process to achieve sub-nanometer level surface finishes and sub-micrometer form accuracies. The surface finish quality is measured as the peak-to-valley distance of the grooves left by the lathe.

Professor Padilla is a mad scientist whose plans have drawn the interest of the police. His latest scheme is to perform a medical experiment on a corpse.

Nolan had not immediately appointed another acting First Sergeant and in his excitement to be underway failed to make sure that all canteens were full. Normally, this is the First Sergeants duty, but it always is the responsibility of the commander to make sure things like this get done. "The Thirsting Time" had begun. The level surface of the Llano Estacado with natural grass cover as seen in 1900.

The edge and inner wall is generally lacking in detail, forming a relatively smooth, gentle slope down to the interior floor. This interior is offset slightly to the southeast, where the inner wall is narrower. The floor is about half the diameter of the crater. There is a small craterlet on the floor along the southern edge, and a few tiny craterlets mark the otherwise relatively level surface.

This geoid defines the nominal sea level surface by means of a spherical harmonics series of degree 360 (which provides about 100 km latitudinal resolution near the Equator). The deviations of the EGM96 geoid from the WGS 84 reference ellipsoid range from about −105 m to about +85 m. EGM96 differs from the original WGS 84 geoid, referred to as EGM84. WGS 84 currently uses the World Magnetic Model 2020.

The interior floor of Stefan is a generally level surface that is marked by several impacts. The most notable is a ring-shaped crater rim projecting up through the southern half of the floor. Near the midpoint is a low hill, possibly the buried remnant of a central peak. Stefan lies at the approximate margin of the Coulomb-Sarton Basin, a 530 km wide impact crater of Pre- Nectarian age.

California mule deer usually browse close to lakes or streams providing their water. From that water source, they may roam 1-2 mi, and typically make their beds in grassy areas beneath trees within such a one-mile radius from both water and forage. Repeatedly used beds often are scratched to a nearly level surface, about 2 m in diameter. Less regularly used bedding areas are seen as flattened grass.

The influence of tectonic activity is very evident in the area. There are many depressions, solution valleys, small karst poljes, and the remains of former river valleys. During the Pliocene the rivers leveled the tectonic upwelling and filled the valleys. Traces were also left by Pliocene glaciation because glaciers created small cirques on what had been a relatively level surface, as well as ground moraines and terminal moraines.

Due to the action of surface tension, small puddles can also form if a liquid is spilt on a level surface. Puddles like this are common on kitchen floors. Puddles tend to evaporate quickly due to the high surface-area-to-volume ratio and tend to be short lived. In cold conditions puddles can form patches of ice which are slippery and difficult to see and can be a hazard to road vehicles and pedestrians.

The city is located on an almost level surface and on very dry soils. As a result, although all of the Minsk Metro stations are under the surface, there are no deep-level stations that are found in most of the ex-Soviet cities. Out of the current 29 stations 19 are pillar-spans and 10 are of vaulted type. Like most of the Soviet metro systems, all of the stations are vividly decorated.

Palo Duro Canyon Geologic map The canyon was formed by the Prairie Dog Town Fork Red River, which initially winds along the level surface of the Llano Estacado of West Texas, then suddenly and dramatically runs off the Caprock Escarpment. Water erosion over the millennia has shaped the canyon's geological formations. Notable canyon formations include caves and hoodoos. One of the best-known and the major signature feature of the canyon is the Lighthouse Rock.

Brant Broughton Gauging Station on the River Brant in Lincolnshire, England. A stream gauge, streamgage or gauging station is a location used by hydrologists or environmental scientists to monitor and test terrestrial bodies of water. Hydrometric measurements of water level surface elevation ("stage") and/or volumetric discharge (flow) are generally taken and observations of biota and water quality may also be made. The location of gauging stations are often found on topographical maps.

The knapping technique they used is well understood by lithics experts. The stone core was placed on a hard level surface such as a large rock, log, or trunk, then struck from above, forcing flakes to separate from the material from underneath. This use of a makeshift anvil is typical of bipolar percussion. There is some confusion about the purpose of a number of small stone and ceramic objects that are cigar-shaped and rasp-like.

One of the most significant rainfall events occurred in 2010 when a monsoonal low from ex-Cyclone Olga created a period of exceptional rainfall. El Niño adverse phases cause a shift in atmospheric circulation; rainfall becomes reduced over Indonesia and Australia, rainfall and tropical cyclone formation increases over the tropical Pacific. The low-level surface trade winds, which normally blow from east to west along the equator, either weaken or start blowing from the other direction.

In geotechnical engineering and contact mechanics the term asperity is used to refer to individual features of unevenness (roughness) of the surface of a discontinuity, grain, or particle with heights in the range from approximately 0.1 mm to the order of metres. Below the asperity level, surface interactions are normally considered to be a material property, arising from mechanisms of adhesion and repulsion at the atomic scale (often accounted for by material friction, atomic friction or molecular friction).

The mouth of the Algar consists of a vertical passage to the interior, that reaches a ramp of debris and gravel. From here there is another decline to the clear waters of the interior pool, approximately from the level surface. The pool is supported by rainwater, and can reach as deep as depth or become dry in summer months, owing to little or no precipitation. The cave itself is remarkable for the unique mineralogical characteristics of its silicate stalactites.

Morphological adaptations that favor this style of flight include high wing loading, long and pointed wingtips, and wings with high aspect ratios. The bat family Molossidae is considered highly specialized at hawking, with unusually high aspect ratios and wing loading. These traits make them capable of incredibly- fast speeds. Mexican free-tailed bats are thought to be the fastest mammal on earth, capable of horizontal flight speeds over a level surface up to 160 km/h (100 mph).

Geodesy is the scientific discipline that deals with the measurement and representation of the earth, its gravitational field and geodynamic phenomena (polar motion, earth tides, and crustal motion) in three- dimensional, time-varying space. The geoid is essentially the figure of the Earth abstracted from its topographic features. It is an idealized equilibrium surface of sea water, the mean sea level surface in the absence of currents, air pressure variations etc. and continued under the continental masses.

The result was a terrace providing "well-drained rich soil and a level surface for growing crops." At prestigious or royal sites, such as Machu Picchu, finely cut stone was used as the outer (visible) face of the retaining wall. The planting surface of an andén is variable, but in the Colca Valley averages wide. The rock and sand layers were to aid drainage of excessive precipitation and were especially important in areas with abundant rainfall.

Dec 11, 1990: d.01. Much of the masonry is characterized by accurately cut rectilinear blocks of such uniformity that they could be interchanged for one another while maintaining a level surface and even joints. However, the blocks do not have the same dimensions, although they are close. The blocks were so precisely cut as to suggest the possibility of prefabrication and mass production, technologies far in advance of the Tiwanaku’s Inca successors hundreds of years later.

The village of Santarfa in Ethiopia is established on a structural flat along a 1000-metre-high escarpment A flat is a relatively level surface of land within a region of greater relief, such as hills or mountains, usually used in the plural. The term is often used to name places with such features, for example, Yucca Flat or Henninger Flats. Flat is also used to describe other level geographic areas as mud flats or tidal flats.

Much of the rim and interior of Ginzel have been flooded, leaving only a faint trace of the rim in the otherwise relatively level surface. The western rim projects more prominently above the surrounding irregular plain. The flooded satellite crater Ginzel L is attached to the southern part of the rim, and a small craterlet lies across the rim to the north. Within the interior is a pair of joined small craterlets in the western half.

Gamow V is attached to the western exterior, and the joined crater pair Gamow A and Gamow B overlie the northeastern side. The eastern rim is the most damaged section, while the rim to the west is free from impacts. The western inner wall does display a fine radial groove texture, but is otherwise nearly featureless. Near the midpoint is a palimpsest, or ghost-crater feature consisting of just the rim projecting up through the otherwise relatively level surface.

Decerebrate cats were made to walk on a level surface with their heads level, tilted up or tilted down. Comparing the decerebrate cats to normal cats showed similar EMG patterns during level walking and EMG patterns that reflected downhill walking with the head titled up and uphill walking with the head tilted down. This study proved that neck proprioceptors and vestibular receptors contribute sensory feedback that alters the gait of the animal. This information may be useful for treatment of gait disorders.

Next, the walls are constructed on a flat level surface with insulation and interior Sheetrock before being lifted by crane into position and secured to the floor sections. The interior ceilings and roof struts are next, vapor sealed and secured to each section’s wall frame before being shingled. Then, the exterior siding is added, along with the installation of doors and windows. Finally, interior finishing, such as sealing the drywall, is completed, along with fixture installation and finishing the electrical and plumbing connections.

Satellite craters Deslandres is the heavily worn and distorted remains of a lunar impact crater. It is located to the southeast of the Mare Nubium, in the rugged southern highlands of the Moon. In dimension it is the third-largest crater formation on the visible Moon, being beaten only by Clavius (231 km) and by the 303-kilometer-diameter walled plain Bailly. The northern and eastern parts of the floor display a relatively level surface, but it is pock- marked with numerous craters.

This is a crater with a slender outer rim that has been worn and eroded by impacts. This rim surrounds an interior that has been flooded by basaltic lava, leaving a level surface with only a central peak at the midpoint projecting up through the floor. There is a small craterlet near the eastern rim, but otherwise the interior floor is nearly featureless. The outer rim has some narrow breaks along the northwest, and the side is lower along the southwestern face.

Screeds are a type of flooring laid on top of the structural element (like reinforced concrete) to provide a level surface on which the "wearing flooring" (the flooring which people see and walk on) is laid.Ingham, p. 130. A screed can also be laid bare, as it provides a long-lasting surface. The aggregate mixed with the cement can be of various size, shape, and material, depending on the texture of the surface needed and how long-lasting it must be.

On the other hand, a wave-front can be regarded as a level surface of displacement of some quantity, such as electric field intensity, hydrostatic pressure, particle number density, oscillatory phase, or probability amplitude. Then the physical meaning of the rays is less evident. This is wave–particle duality for a single particle in ordinary three-dimensional physical space or for a wave of some property of a medium with a spatial distribution of properties that is mostly continuous but not homogeneous.

To check the accuracy of a carpenter's type level, a perfectly horizontal surface is not needed. The level is placed on a flat and roughly level surface and the reading on the bubble tube is noted. This reading indicates to what extent the surface is parallel to the horizontal plane, according to the level, which at this stage is of unknown accuracy. The spirit level is then rotated through 180 degrees in the horizontal plane, and another reading is noted.

This is an especially safe method for the exit as the patrons are usually disoriented by the attraction. If the tunnel is installed on a level surface, a ramp should be used, again to provide safety for the user. Steps can be used if space is limited, but lighting should be provided to illuminate the steps for the patrons' safety. The ends of the tunnel need to be enclosed to prevent light entering and to help control the flow of patrons through the attraction.

There is a gap in the rims where these two craters are joined, and the interior floors have been resurfaced by lava, leaving a level surface across the bottom of both craters. This floor is nearly featureless, and has the same low albedo as the dark lunar mare to the north. The outer rim has a small crater joined to the eastern edge of the northern gap, but is otherwise not overlain by any notable craters. The crater's name was approved by the IAU in 1973.

A C-47 Skytrain supply aircraft was the first plane to land on the first steel-mat runway constructed in France after the invasion of Normandy. On Pacific islands the matting was typically covered with crushed and rolled coral or soil to form a level surface. The perforated and channeled design of the matting created strength and rigidity and facilitated drainage. A runway two hundred feet wide and 5000 feet (1500 m) long could be created within two days by a small team of engineers.

The Terrapin was powered by two Ford V8 engines mounted side-by-side, with each motor driving the wheels on one side. Wheel braking was used to steer, the brakes being operated by levers. On a level surface, the vehicle was supported on the four middle wheels, the front and rear wheels remaining clear of the surface (the front pair being raised significantly, the rear pair only slightly). The front and rear wheels provided support and traction on soft surfaces and when climbing slopes, such as riverbanks.

The rope for the Chequerbent incline is made by Webster of Sunderland and is in circumference, it weighs about when new and costs £2 10s per hundredweight. This rope when partially worn is transferred to the Daubhill incline. The width occupied by the railway on a level surface is and the track is ballasted with small coal. The OS map of 1849 shows the original B&LR; line running to the canal as well as the newer K&LJnR; line running over the bridge.

Its usual habitat included low-altitude river valleys and floodplains, preferring vertical banks suitable for tunneling when breeding, but readily digging vertical burrows in the level surface of small salt islands. This is a highly sociable species, gathering in large flocks, in or out of breeding season. They roost communally in trees or reedbeds, and disperse widely during the day. Nesting is at the end of a 1 to 2 meter long burrow in an earthen bank, where they lay from 2 to 5 eggs.

The Department of Public Works fixed this problem by mixing clay with the gravel. This era was followed by four-horse teams pulling a sulky plow across the roads, eliminating ruts and forming a hard and level surface to drive upon. The 1920s were indeed years of road work; however in these pioneering days there was little background or guidelines to go by. Early road work consisted of levelling roads and filling in low spots which would collect water to make travel easier by the first automobiles.

However, early designs came in a variety of other shapes. Some resembled candlesticks, with a bulb mounted at the top of a battery tube fixed to a flat base, with a handle. Many resembled lanterns, consisting of a battery box with a handle and the lamp and reflector attached to the front. Electric lanterns are used for lighting the broad area immediately around the lantern, as opposed to forming a narrow beam; they can be set down on a level surface or attached to supports.

Younger leaves are preferred to older, and tree leaves are preferred to liana leaves. Individual maned sloths have reported to travel over a home range of , with estimated population densities of . Maned sloths rarely descend from the trees because, when on a level surface, they are unable to stand and walk, only being able to drag themselves along with their front legs and claws. They travel to the ground only to defecate or to move between trees when they cannot do so through the branches.

Manual mining techniques resulted in a moonscape of limestone pinnacles as all phosphate was removed from around the limestone pinnacles and there was little soil left to support regrowth. This contrasts with more recently mined areas where machines have left a much more level surface and enough phosphate and soil to allow limited regrowth. One physical remnant of this early period is the Phosphate Hill cemetery and the marker for the cemetery which is located on the main road. This cemetery contains a large number of headstones including colourful Chinese memorials.

Ekranoplan A-90 Orlyonok A ground-effect vehicle (GEV), also called a wing-in- ground-effect (WIG), ground-effect craft, wingship, flarecraft or ekranoplan (), is a vehicle that is designed to attain sustained flight over a level surface (usually over the sea) by making use of ground effect, the aerodynamic interaction between the wings and the surface. The type is typically intended to operate from water like a flying boat, but some can operate over any flat area such as frozen lakes or flat plains similar to a hovercraft.

Extract of page 12.30 Kinetic energy may be best understood by examples that demonstrate how it is transformed to and from other forms of energy. For example, a cyclist uses chemical energy provided by food to accelerate a bicycle to a chosen speed. On a level surface, this speed can be maintained without further work, except to overcome air resistance and friction. The chemical energy has been converted into kinetic energy, the energy of motion, but the process is not completely efficient and produces heat within the cyclist.

Its function was to separate the brackish waters of Lake Texcoco (ideal for the agricultural technique Chināmitls) from the fresh potable water supplied to the settlements. However, after the Europeans destroyed Tenochtitlan, the levee was also destroyed and flooding became a major problem, which resulted in the majority of The Lake to be drained in the 17th Century. Levees are usually built by piling earth on a cleared, level surface. Broad at the base, they taper to a level top, where temporary embankments or sandbags can be placed.

By 1966, 35 miles demonstrated a drop of 1 feet, 3 feet elevation drop in 15 mile stretch, 5 foot decrease in a 5-mile portion, and 2 feet of the canal demonstrated a drop of 6 feet. Land subsidence in the region is due to constant over-drafting of underground water. Another key factor is due to the San Joaquin Valley's geomorphological structure, having young continental, unconsolidated sandy-silty-clayish soils, resting on old unconsolidated marine beds. Impacts of the land subsidence lead to a decrease between bridges and water level surface.

The large surface area of the contained liquid helps evaporate it, the narrow top traps the aroma inside the glass, while the rounded bottom allows the glass to be cupped in the hand, thus warming the liquor. Most snifters will hold , but are almost always filled to only a small part of their capacity. Most snifters are designed so that when placed sideways on a level surface, they will hold just the proper amount before spilling. A variant is called a pipe glass or pipe snifter, used for port and brandy.

73 This top level surface permitted a smoother shape and protected the larger stones in the road structure from iron wheels and horse hooves. To keep the running surface level with the countryside, this road was put in a trench, which created drainage problems. These problems were addressed by changes that included digging deep side ditches, making the surface as solid as possible, and constructing the road with a difference in elevation (height) between the two edges, that difference being referred to interchangeably as the road's camber or cross slope.

Her dissertation work focused on investigating molecular-level surface reactivity and kinetics of metal surfaces using electron spectroscopy, laser desorption, and Fourier transform mass spectrometry techniques. She also designed and built peripheral components for a variable temperature, ultra- high vacuum scanning tunneling microscopy system. In 1997, Caldwell Dyson received the Camille and Henry Drefus Postdoctoral Fellowship in Environmental Science to study atmospheric chemistry at the University of California, Irvine. There she investigated reactivity and kinetics of atmospherically relevant systems using atmospheric pressure ionization mass spectrometry, Fourier transform infrared and ultraviolet absorption spectroscopies.

The IUGG standard meridian is, to the nearest millimetre, , one arc- minute of which is , explaining the SI standardization of the nautical mile as , more than less than the geographical mile. The sea-level surface of the Earth (the geoid) is irregular, so the actual length of the equator is not so easy to determine. Aviation Week and Space Technology on 9 October 1961 reported that measurements using the Transit IV-A satellite had shown the equatorial diameter from longitude 11° West to 169° East to be greater than its diameter ninety degrees away.

Zorbing (also known as globe-riding, sphereing, orbing) is the recreation or sport of rolling downhill inside an orb, typically made of transparent plastic. Zorbing is generally performed on a gentle slope but can also be done on a level surface, permitting more rider control. In the absence of hills, some operators have constructed inflatable, wooden, or metal ramps. Due to the buoyant nature of the orbs, Zorbing can also be carried out on water, provided the orb is inflated properly and sealed once the rider is inside.

The next machine is usually a single smooth drum compactor that compacts the high spots down until the soil is smooth. This is usually done in combination with a motor grader to obtain a level surface. Sometimes at this stage a pneumatic tyre roller is be used. These rollers feature two rows (front and back) of pneumatic tyres that overlap, and the flexibility of the tyres provides a kneading action that seals the surface and with some vertical movement of the wheels, enables the roller to operate effectively on uneven ground.

Young stick insects are diurnal (daytime) feeders and move around freely, expanding their foraging range. Stick insects have two types of pads on their legs: sticky "toe pads" and non- stick "heel pads" a little further up their legs. The heel pads are covered in microscopic hairs which create strong friction at low pressure, enabling them to grip without having to be peeled energetically from the surface at each step. The sticky toe pads are used to provide additional grip when climbing but are not used on a level surface.

Comparatively few ant bed structures are known to survive in Queensland. Another building described as being a dairy located in the Clermont area is Irlam's farm building, which is constructed of rammed earth mixed with ant bed. There is brick quoining to the corners of the stone building at Fleurs and to window and door openings. To accommodate the original verandah floor joists, a brick-on-edge course set between two layers of timber planking, provided a level surface for the joist housing around the perimeter of the building.

Although height is relative to a plane of reference, most measurements of height in the physical world are based upon a zero surface, known as sea level. Both altitude and elevation, two synonyms for height, are usually defined as the position of a point above the mean sea level. One can extend the sea-level surface under the continents: naively, one can imagine a lot of narrow canals through the continents. In practice, the sea level under a continent has to be computed from gravity measurements, and slightly different computational methods exist; see Geodesy, heights.

Use maximum weight 30 pound jackhammers to remove the concrete remaining between the saw cuts. If the concrete removal operations cause damage to the pavement that is to remain, discontinue concrete removal operations and only resume after taking corrective measures. During concrete removal operations, use a small bush hammer as necessary to produce a flat, level surface within the slot so the backfill flows and consolidates under the dowel bars. Complete installation of retrofit dowels, with dowel bars and backfill placed prior to reopening the lane to public traffic.

These ploughs date back to the days of the steam engine and the horse. In almost universal use on farms, they have right and left-handed mould boards, enabling them to work up and down the same furrow. Reversible ploughs may either be mounted or semi- mounted and are heavier and more expensive than right-handed models, but have the great advantage of leaving a level surface that facilitates seedbed preparation and harvesting. Very little marking out is necessary before ploughing can start; idle running on the headland is minimal compared with conventional ploughs.

The interior floor of d'Alembert is a relatively level surface, at least in comparison with the rough terrain that surrounds the crater rim. It is marked with a number of small crater impacts, the largest being d'Alembert G and d'Alembert E toward the eastern rim. In the southwest, the floor is more irregular due to the outer rampart and layers of ejecta from Slipher. A pair of shallow clefts in the floor surface radiate away from this crater, beginning near the midpoint of d'Alembert and reaching half-way toward the inner wall.

The shell of Lottia instabilis is specially adapted by the shape of its rim to adhere to the holdfasts and stipes of kelp. The sides of the rim are elongated and nearly parallel, but both anterior and posterior end are raised up; this means it cannot lie flat and seal itself to a level surface but it can seal to a curved surface. The shell is smooth with an even margin. It is often mainly brownish, and may be paler near the apex, which is somewhat towards the anterior end of the shell.

When the muscles contract, the energy is first transferred into the stretched tendon which is wrapped around the ankle bone. Then the muscles stretch again at the same time as the tendon releases its energy like a catapult to produce a powerful acceleration beyond the limits of muscle-powered acceleration. A similar mechanism has been documented in locusts and grasshoppers. ;Walking and running Phrynomantis bifasciatus walking on a level surface Frogs in the families Bufonidae, Rhinophrynidae, and Microhylidae have short back legs and tend to walk rather than jump.

This gave him a level surface of 2.7 to 3.7 metres outside the cave. Portions on either side of the rock were closed off with stones and clay mortar leaving an opening just over 1 metre wide and 2 metres high to enter the cave. Outside he planted flowers on both sides of a path that led to the top of the retaining wall. Turning right, he then followed along the top of the wall for about 6 metres where he had made a pathway a little over half a metre wide that led to and from the cave.

The Old Post Office is located in Liberty's village center, set close to the south side of Main Street (Maine State Route 173), two doors east of the public library. It is a small single-story eight-sided wood frame structure, covered by a low-pitch octagonal roof and clapboard siding. It has no foundation beyond a small amount of rubblestone to provide a level surface, and is built on top of hand-sawn beams measuring in cross section. The only entrance is in the street-facing facade, with sash windows in the other seven walls.

Chevrolet Suburban raised with aftermarket wheels and suspension mods note much greater ground clearance under front with independent suspension, compared to under rear live axle differential. Ride height or ground clearance is the amount of space between the base of an automobile tire and the lowest point (typically the axle); or, more properly, to the shortest distance between a flat, level surface, and the lowest part of a vehicle other than those parts designed to contact the ground (such as tires, tracks, skis, etc.). Ground clearance is measured with standard vehicle equipment, and for cars, is usually given with no cargo or passengers.

The bird-dropping spider is a master of deception. It crouches stationary on a leaf or other level surface and exhibits an elaborate combination of form and colour, the posture it adopts and the character of its web so as to simulate accurately a patch of bird's excreta. The underside of its abdomen is chalky white and its legs black. It weaves a small irregular white web on the surface of a prominently placed leaf and adopts an upside-down pose near the centre of the web with its legs folded, anchoring itself in place with some spines on its legs.

Standard terminology used to describe understeer and oversteer are defined by the Society of Automotive Engineers (SAE) in document J670SAE International Surface Vehicle Recommended Practice, "Vehicle Dynamics Terminology", SAE Standard J670, Rev. 2008-01-24 and by the International Organization for Standardization (ISO) in document 8855.International Organization for Standardization, "Road vehicles – Vehicle dynamics and road- holding ability – Vocabulary", ISO Standard 8855, Rev. 2010 By these terms, understeer and oversteer are based on differences in steady-state conditions where the vehicle is following a constant-radius path at a constant speed with a constant steering wheel angle, on a flat and level surface.

207 In his attempts to find the way down, Evans removed his goggles and subsequently suffered agonies of snow blindness that made him into a passenger.Preston, pp. 206–08 When the party was finally free of the glacier and on the level surface of the Barrier, Evans began to display the first symptoms of scurvy.Crane, pp. 555–56 By early February he was in great pain, his joints were swollen and discoloured, and he was passing blood. Through the efforts of Crean and Lashly the group struggled towards One Ton Depot, which they reached on 11 February.

Dodger Stadium was the first Major League Baseball stadium since the initial construction of the original Yankee Stadium to be built using 100% private financing, and the last until Oracle Park in San Francisco opened in 2000. Ground was broken for Dodger Stadium on September 17, 1959. The top of local ridges were removed and the soil was used to fill in Sulfur and Cemetery Ravines to provide a level surface for a parking lot and the stadium. A local elementary school (Palo Verde) was simply buried and sits beneath the parking lot northwest of third base.

Limits of deviation with sample of an actual stick superimposed in green. Limits of deviation, sample curves. To describe the dimensions of head and handle the hockey stick is envisaged to be placed with the bottom curve of the stick head on a level surface, the x-axis, with the stick-handle perpendicular to it (the y-axis). The y-axis runs from an intersection with the x-axis (0) vertically through the midpoint of the top of the handle. The Head is the part from the x-axis to the line C-C (diagram) a vertical distance of 100 mm.

The Shoe Board recognized that fit would be imperfect, and recommended breaking in new shoes rapidly by standing in them in three inches of water for ~5 minutes, to soak the leather through, and then walking on a level surface outdoors for ~1 hour, or until the shoes have dried. Failing this, they suggested breaking them in by wearing them for initially short periods, progressively lengthened, to break in the shoe rather than the foot. They also recommended using special shoe stretchers with removable pegs to stretch the toeboxes wider, and stretch bumps over blisters, corns, and bunions.

Oblique view from Apollo 8 at a high sun angle, demonstrating the crater's dark floor Oblique Apollo 14 Hasselblad camera image Lomonosov is a lunar impact crater that is located just behind the western limb of the Moon. It is almost attached to the east-northeastern outer rim of the larger crater Joliot, and overlies the southern rim of Maxwell. Attached to the southern rim of Lomonosov is the smaller Edison. The interior floor of Lomonosov has been resurfaced with lava flows, leaving a dark, level surface marked only by a few tiny craterlets and some streaks of ray material from Giordano Bruno.

Lopodytes species are small-to- medium-sized bugs, measuring between 10 and 20 mm in length. They are however very gracile and elongate in build, with nearly parallel sides, so they are far less massive than most insects of a similar bodily length. Usually they occur in savanna grass and similar vegetation, but on a level surface they generally adopt a very horizontal posture that emphasizes their resemblance to the thread assassins, the Emesinae. They easily may be confused with the Emesinae, but they are somewhat less gracile, typically 50% to 100% larger in linear measurement, and unlike the Emesinae, they do not have raptorial front legs.

Oblique view facing south from Apollo 8 Oblique view facing south from Apollo 16 Crozier is a lunar impact crater that is located on the southwest edge of Mare Fecunditatis, a lunar mare in the eastern part of the Moon's near side. It lies to the east-northeast of the prominent crater Colombo, and southeast of the small crater Bellot. The narrow rim of this crater forms a distorted enclosure that has outward bulges along the northwest, southwest, and southeastern sides. The interior floor has been resurfaced and nearly filled by basaltic lava, producing a level surface with a low albedo that matches the dark hue of the nearby lunar mare.

A block of chalk or some similar material is reduced to a level surface. On this surface, a design is drawn with a glutinous ink, the ink being sufficiently fluid to penetrate some little distance into the porous chalk. The ink having become dry, gentle friction is applied to the surface of the block so as gradually to rub away those parts of the chalk which are not indurated by the glutinous ink. The lines of the drawing being thus left in relief, a perfect model of the required printing block is obtained and this model is next hardened by immersion in a bath containing a solution of an alkaline silicate.

Theatres constructed after the beginning of the 20th century feature a raked audience section. This change back to the method of construction seen in Greek and Roman theaters (flat stage and terraced audience) was effected due to the difficulty encountered when one tries to walk across a sloped surface, which had resulted in unnatural movement patterns to avoid the appearance of limping caused by the non-level surface. Raked stages can still be seen in some opera, Broadway and West End productions, where a temporary raked acting surface is built over a theatre's permanent flat stage. Creating a raked stage can also assist set designs which are designed with forced perspective.

The Long Branch Historical Museum Association, which owns the structure, has mounted an aggressive effort to restore the Church of the Presidents and its grounds, on which the tea house rests.www.churchofthepresidents.org Restoration of the tea house is part of the four-phase preservation plan to preserve the Church of the Presidents, currently in its second phase of restoration. The Garfield Tea House is located at 1260 Ocean Avenue in Long Branch, just across the street from the Atlantic Ocean. Preservation of the tea house will require lifting the building above grade, excavating to create a level surface, pouring a six-inch reinforced slab, and lowering the building onto the new foundation.

Due to the abrupt shift in its center of gravity caused by separation, the fuselage would have performed an abrupt pitch-up maneuver in order to avoid a collision with the warhead. A photo sequence showing the warhead's separation sequence One unusual capability of the Snark missile was its ability to fly away from its launch point for up to 11 hours, and then return for a landing. If its warhead did not detach from its body, then the Snark could be flown repeatedly. Lacking any landing gear, it would have been necessary for the Snark to skid to a stop on a flat, level surface.

Probability density of stress S (red, top) and resistance R (blue, top), and of equality (m = R - S = 0, black, bottom). Distribution of stress S and strength R: all the (R, S) situations have a probability density (grey level surface). The area where the margin m = R - S is positive is the set of situation where the system is reliable (R > S). Stress–strength analysis is the analysis of the strength of the materials and the interference of the stresses placed on the materials, where "materials" is not necessarily the raw goods or parts, but can be an entire system. Stress-Strength Analysis is a tool used in reliability engineering.

The vertical deflection (VD), also known as deflection of the plumb line and astro-geodetic deflection, at a point on the Earth is a measure of how far the gravity direction (plumb line) has been shifted by local mass anomalies such as nearby mountains. They are widely used in geodesy, for surveying networks and for geophysical purposes. The vertical deflection are the angular components between the true zenith (plumb line) and the line perpendicular to the surface of the reference ellipsoid chosen to approximate the Earth's sea- level surface. VDs are caused by mountains and by underground geological irregularities and can amount to angles of 10″ (flat areas) or 20–50″ (alpine terrain).

European Space Agency. This technique has become a universally recognised complimentary data source to seismic surveying and other offshore exploration tools, and is used by most of the world’s major oil companies who draw on a global database compiled and maintained by CGG-NPA. Growing availability of satellite radar during the 1990s led Press to focus NPA on developing methods using interferometric principles to detect small amounts of ground surface movement that remain difficult to survey with ground-based techniques. The ability to measure millimetric-level surface changes due to both geological and anthropogenic effects introduced a new dimension to environmental studies in disciplines ranging from earthquake and volcano studies to groundwater and oil extraction and engineering geology.

Vandeikya Local Government area is dominated by undulating terrain with much of the area being below 183 m (600 ft) above the sea level. Surface drainage is generally good with almost all the rivers being seasonal, notably river Aya and river Be. The climate is tropical sub humid with the mean annual rainfall of between 1,200 and 2,000 mm (47" and 79") averaging seven months in the year, while the mean annual temperature is 32.5 °C (90 °F). The wet season is from April to October or November while the dry season is November to March. Agriculture is the mainstay of the people; with arable land for sheep, goats and cattle rearing.

The number of axles was determined by the weight limit for European railways of 17 tonnes per axle. These were the longest range guns available to the French and US Army during the first world war and although well regarded they were time- consuming to set up with 2–5 days of site preparation being required. The site preparation consisted of excavating a large pit underneath the breech of the gun and lining it with timbers to accommodate the recoil of the gun at high angles of elevation +37°. Sections of the rail bed were also reinforced in front of and behind the carriage to provide a level surface for the gun.

The physical components of the NSRS are reflected in its height system, defined by the vertical datum NAVD88. This datum is a network of orthometric heights obtained through spirit leveling. Because of the close relationship between height and Earth's gravity field, NGS also collects and curates terrestrial gravity measurements and develops regional models of the geoid (the level surface that best approximates sea level) and its slope, the deflection of the vertical. NGS is responsible for ensuring the accuracy of the NSRS over time, even as the North American plate rotates and deforms over time due to crustal strain, post-glacial rebound, subsidence, elastic deformation of the crust, and other geophysical phenomena.

However, the magnitude of the friction force itself depends on the normal force, and hence on the mass of the block. If an object is on a level surface and the force tending to cause it to slide is horizontal, the normal force N\, between the object and the surface is just its weight, which is equal to its mass multiplied by the acceleration due to earth's gravity, g. If the object is on a tilted surface such as an inclined plane, the normal force is less, because less of the force of gravity is perpendicular to the face of the plane. Therefore, the normal force, and ultimately the frictional force, is determined using vector analysis, usually via a free body diagram.

But since the ocean also bulges, like Earth and its atmosphere, Chimborazo is not as high above sea level as Everest is. More precisely, the surface of the Earth is usually approximated by an ideal oblate ellipsoid, for the purposes of defining precisely the latitude and longitude grid for cartography, as well as the "center of the Earth". In the WGS-84 standard Earth ellipsoid, widely used for map-making and the GPS system, the radius of the Earth is assumed to be at the equator and center-to-pole; meaning a difference of in the radii and in the diameters, and a relative flattening of 1/298.257223563. The sea level surface is much closer to this standard ellipsoid than the surface of the solid Earth is.

In the United States, federal law exempts low-speed electric bicycles from Department of Transportation and NHTSA motor vehicle regulations, and they are regulated under federal law in the same manner as ordinary bicycles.DOT/NHTSA Administration Docket No. NHTSA 2005–21467, Two- and Three-Wheeled Vehicles, U.S. Federal Register (Notices), Vol. 70, No. 114, Wednesday, June 15, 2005, p. 34813 The Consumer Product Safety Act defines the term low speed electric bicycle as a two- or three- wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts (1 horsepower), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20 mph (15 U.S.C. 2085(b)).

In 2006 a bill was passed that changed the definition of a bicycle to include a bicycle that has an electric motor of less than 1 hp (750 watts). The new definition, found in Iowa Code section 321.1(40)c states: "Bicycle" means either of the following: (1) A device having two wheels and having at least one saddle or seat for the use of a rider which is propelled by human power. (2) A device having two or three wheels with fully operable pedals and an electric motor of less than 750 watts (one horsepower), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden, is less than 20 miles per hour.

The engine automatically shuts down whenever possible (cruising downhill at speeds of up to 85km/h when the battery is not fully charged or cruising on a level surface at speeds of up to ~60km/h), when coming to a stop the HDi engine shuts down at speeds below 30km/h. Restarting can occur at any moment, if the HYbrid4 control unit determines that additional power is needed; or the battery needs to be topped up; or the A/C compressor needs to kick in. The engine also restarts when the battery is fully charged and the vehicle is going downhill, as to offer additional engine braking, no fuel is used in this mode, but ZERO EMISSION is not displayed, as the HDi engine is rotating.

In contrast to the "OK sign," Ericson's test isolates the action of the FDP and FPL while eliminating the contribution of the tenodesis effect and other adaptations that patients may use, usually unconsciously, to augment distal pincer strength. Failing to control for compensatory wrist tenodesis can mask an underlying proximal median nerve weakness in a patient who can otherwise make a normal OK-sign. While facing the patient in what resembles an arm wrestling stance, with elbows planted firmly on a level surface and maintained touching the thorax, the examiner uses one hand to lock the patient's wrist in neutral, around which the patient curls his fingers. With the other hand, the examiner then attempts to "peel" back the tips of each individual finger against patient resistance.

During the warmer summer months, low-level surface troughs normally cross over the west coast of Australia, which often leads to isolated thunderstorm development in inland Western Australia, only occasionally reaching the coast (such as on 20 December 2009, when a storm developed south of Perth and gave the city of Mandurah of rain for the month). However, on 21 and 22 March 2010, high surface dew points and temperatures combined with a low to the west of WA caused rare northerly winds to occur. This meant any storms that formed would be pushed southwards instead of the normal easterly pattern. 21 March 2010 Storms formed in the Geraldton region during the afternoon, putting an end to the city's fourth-longest dry spell, with of rainfall recorded at Geraldton.

A diorama in the Museum of Natural History in Milan (Italy) Modern museum dioramas may be seen in most major natural-history museums. Typically, these displays use a tilted plane to represent what would otherwise be a level surface, incorporate a painted background of distant objects, and often employ false perspective, carefully modifying the scale of objects placed on the plane to reinforce the illusion through depth perception in which objects of identical real-world size placed farther from the observer appear smaller than those closer. Often the distant painted background or sky will be painted upon a continuous curved surface so that the viewer is not distracted by corners, seams, or edges. All of these techniques are means of presenting a realistic view of a large scene in a compact space.

This is easily determined by the height ratio of any object to the size of its shadow (if the height is measured vertical to the earth's gravitational field, the projected shadow is ideally measured on a flat, level surface; furthermore, for objects wider than skulls or poles, the height and length are best measured relative to the same occluding edge). The greatest risk is at solar noon, when shadows are at their minimum and the sun's radiation passes most directly through the atmosphere. Regardless of one's latitude (assuming no other variables), equal shadow lengths mean equal amounts of UV radiation. The skin and eyes are most sensitive to damage by UV at 265–275 nm wavelength, which is in the lower UVC band that is almost never encountered except from artificial sources like welding arcs.

The Ohio Revised Code 4511.01 distinguishes motorized bicycles and mopeds from motorcycles or scooters by describing them as "...any vehicle having either two tandem wheels or one wheel in the front and two wheels in the rear, that is capable of being pedaled and is equipped with a helper motor of not more than fifty cubic centimeters piston displacement that produces no more than one brake horsepower and is capable of propelling the vehicle at a speed of no greater than twenty miles per hour on a level surface." One brake horsepower converts to 0.75 kW, or (rounded) 750W. Thus, a bicycle with an electric helper motor operating under 750W, and not propelling the bicycle over 20 mph, does not qualify to be registered under Ohio state law. Local jurisdictions may have other regulations.

This class of games includes any game in which the skill element involved relates to manual dexterity or hand-eye coordination, but excludes the class of video games (see below). Games such as jacks, paper football, and Jenga require only very portable or improvised equipment and can be played on any flat level surface, while other examples, such as pinball, billiards, air hockey, foosball, and table hockey require specialized tables or other self-contained modules on which the game is played. The advent of home video game systems largely replaced some of these, such as table hockey, however air hockey, billiards, pinball and foosball remain popular fixtures in private and public game rooms. These games and others, as they require reflexes and coordination, are generally performed more poorly by intoxicated persons but are unlikely to result in injury because of this; as such the games are popular as drinking games.

Maryland defines an "electric bicycle" as a vehicle that (1) is designed to be operated by human power with the assistance of an electric motor, (2) is equipped with fully operable pedals, (3) has two or three wheels, (4) has a motor with a rating of 500 watts or less, (5) and is capable of a maximum speed of 20 miles per hour on a level surface when powered by the motor. (Senate Bill 379, approved by the Governor 5/5/2014, Chapter 294.) This legislation excludes "electric bicycle" from the definition of "moped", "motorized minibike", and "motor vehicle", and removes the titling and insurance requirements required for electric bicycles under prior Maryland law. Before September 20, 2014, Maryland law had classified an electric bicycle as a moped. Mopeds are specifically excluded from the definition of "motor vehicle" per § 11-135 of the Maryland Transportation Code.

If the driver presses the accelerator beyond a certain point, the HDi engine restarts automatically as to offer better acceleration and the vehicle goes to AUTO mode. Auto Start-Stop is part of the HYbrid4 system and is available in all modes except for 4WD when the engine is constantly running so that the reversible alternator can top up the battery and provide constant rear drive. The engine automatically shuts down whenever possible (cruising downhill at speeds of up to 85 km/h when the battery is not fully charged or cruising on a level surface at speeds of up to ~60 km/h), when coming to a stop the HDi engine shuts down at speeds below 30 km/h. The Auto Start-Stop function is possible with the use of the BOSCH SMG (Separate Motor-Generator) 138/80 (138 mm in diameter, 80 mm long) reversible starter-generator motor.

As of May 14, 2019, a new vehicle class (“Low-speed electric bicycle”) was added to NJRS Title 39, described as “a two or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts, whose maximum speed on a paved level surface, when powered solely by a motor, while operated by a person weighing 170 pounds, is less than 20 miles per hour.” Additionally, the existing class of “motorized bicycles” has been expanded to include—in addition to gas-powered vehicles such as mopeds—electric bicycles that can achieve speeds between 20 mph and 28 mph. For these vehicles, a driver's license and registration are still required. Under previous regulations, all e-bikes were classified as motorized bicycles (mopeds) and required registration, but could not actually be registered since the law was written only for gas-powered vehicles. The new legislation, which applies to both “pedal-assist” and “throttle” bicycles, removes e-bikes from that legal gray area.

The exact value of the magnetic declination is place-dependent and varies over time, though declination is frequently given on the map itself or obtainable on-line from various sites. If the hiker has been following the correct path, the compass' corrected (true) indicated bearing should closely correspond to the true bearing previously obtained from the map. A compass should be laid down on a level surface so that the needle only rests or hangs on the bearing fused to the compass casing – if used at a tilt, the needle might touch the casing on the compass and not move freely, hence not pointing to the magnetic north accurately, giving a faulty reading. To see if the needle is well leveled, look closely at the needle, and tilt it slightly to see if the needle is swaying side to side freely and the needle is not contacting the casing of the compass.

NAPFA involves a series of five stations and a 2.4-km (1.5-mile) Walk-Run for secondary school students or a 1.6-km (1-mile) Walk- Run for primary school students. All of the 5 station tests are attempted on the same day, with a 2-5 minute rest period permitted between stations. The Walk-Run item is usually attempted on a different day, although sometimes a 2-week window limit is set. The test items are: # Sit-ups: Maximum in one minute # Pull-ups (secondary schools)/Push-ups (ITE/Poly/JC/MI) (for males 15 years old and above) or Inclined Pull-ups (for females and males below 15 years old): Maximum in half-a-minute # Sit-and-Reach: Maximum distance # Shuttle Run: Minimum time for two laps of fixed distance # Standing Broad Jump: Maximum distance # 2.4-km Run (1.5-mile Run) [1.6-km Run (1-mile run) for primary schools]: Minimum time on firm and level surface Performances are then compared to a chart and the grades from A to F for each test item.
