Importantly, the fraction of capacitated (and, hence, chemotactically responsive) spermatozoa is low (~10% in humans), the life span of the capacitated/chemotactic state is short (1–4 hours in humans), a spermatozoon can be at this state only once in its lifetime, and sperm individuals become capacitated/chemotactic at different time points, resulting in continuous replacement of capacitated/chemotactic cells within the sperm population, i.e., prolonged availability of capacitated cells.Cohen-Dayag, A., Ralt, D., Tur-Kaspa, I., Manor, M., Makler, A., Dor, J., Mashiach, S. and Eisenbach, M.

This raised the possibility that, in mammals, chemotaxis is not solely a guidance mechanism but it is also a mechanism of sperm selection.

It was proposed that capacitated spermatozoa might detach from the oviductal surface faster than non-capacitated spermatozoa, enabling them to swim into the main current. To understand the mechanism of sperm turning in rheotaxis, quantitative analysis of human sperm flagellar behavior during rheotaxis turning was carried out. The results revealed, both at the single cell and population levels, that there is no significant difference in flagellar beating between rheotaxis turning spermatozoa and free-swimming spermatozoa.Zhang, Z., Liu, J., Meriano, J., Ru, C., Xie, S., Luo, J., and Sun, Y.

The opposite happens in response to an increase in temperature. This suggests that when capacitated spermatozoa swim up a temperature gradient, turns are repressed and the spermatozoa continue swimming in the gradient direction. When they happen to swim down the gradient, they turn again and again until their swimming direction is again up the gradient.

When human and mouse spermatozoa are exposed to a fluid flow, roughly one half of them (i.e., both capacitated and noncapacitated spermatozoa) reorient and swim against the current. The flow, which is prolactin-triggered oviductal fluid secretion, is generated in female mice within 4 h of sexual stimulation and coitus. Thus, rheotaxis orients spermatozoa towards the fertilization site.

Capacitated human spermatozoa swim in rather straight lines interrupted by turns and brief episodes of hyperactivation. Each such episode results in swimming in a new direction. When the spermatozoa sense a decrease in temperature, the frequency of turns and hyperactivation events increases due to increased flagellar-wave amplitude that results in enhanced side-to-side head displacement. With time, this response undergoes partial adaptation.

Fertilization occurs in the ampulla, the section of the oviduct that curves around the ovary. Capacitated sperm are attracted to progesterone, which is secreted from the cumulus cells surrounding the oocyte. Progesterone binds to the CatSper receptor on the sperm membrane and increases intracellular calcium levels, causing hyperactive motility. The sperm will continue to swim towards higher concentrations of progesterone, effectively guiding it to the oocyte.

Depending on the total amount of spermatozoa in the semen sample, either low or high, it can be just washed or capacitated via swim-up or gradients, respectively. A medical animation still showing the ICSI procedure. The procedure is done under a microscope using multiple micromanipulation devices (micromanipulator, microinjectors and micropipettes). A holding pipette stabilizes the mature oocyte with gentle suction applied by a microinjector.

Capacitated and hyperactivated sperm respond to these gradients by changing their behaviour and moving towards the cumulus-oocyte complex. Other chemotactic signals such as formyl Met-Leu-Phe (fMLF) may also guide spermatozoa. The zona pellucida, a thick layer of extracellular matrix that surrounds the egg and is similar to the role of the vitelline membrane in sea urchins, binds the sperm. Unlike sea urchins, the sperm binds to the egg before the acrosomal reaction.

A disintegrin and metalloprotease 3, or ADAM3, belongs to a family of peptidase proteins referred to as ADAMs. Many of these are solely found in spermatogenic cells, specifically in the anterior portion of capacitated spermatozoa heads. This membrane protein is critical for crucial steps in fertilization such as migration of sperm through the uterus to the oviduct as well as binding to the zona pellucida. Inactivation of ADAM3 is a cause of male infertility.

The initiator was the priest and researcher Eilert Sundt, and Mohn. Mohn was also involved in the workers' society Christiania Arbeidersamfund, and through his research on child labour among other things, he capacitated social reform. His last work was Norges Land og Folk, requisitioned by the Norwegian Parliament in 1874, and meant to be a grand reference work. However, he never finished a single volume, as he died in February 1882 in Kristiania.

Arcs generally have cost & capacity parameters. A recurring problem is trying to determine the minimum cost route between two points in a capacitated network. The idea of the algorithm is to identify out-of-kilter arcs and modify the flow network until all arcs are in-kilter and a minimum cost flow has been reached. The algorithm can be used to minimize the total cost of a constrained flow in an oriented network.

Cuny became convinced that the field of disaster management needed to be professionalized and capacitated. This led him to conceptualize and co-found the University of Wisconsin Disaster Management Center (DMC). In 1982, Cuny and the University convened two dozen global experts to map out the DMC's agenda and training topics. The Disaster Management Center was the first institution to offer access to training for humanitarian workers in the field through correspondence courses (instead of through prohibitively expensive travel to remote training sites).

Capacitated minimum spanning tree is a minimal cost spanning tree of a graph that has a designated root node r and satisfies the capacity constraint c. The capacity constraint ensures that all subtrees (maximal subgraphs connected to the root by a single edge) incident on the root node r have no more than c nodes. If the tree nodes have weights, then the capacity constraint may be interpreted as follows: the sum of weights in any subtree should be no greater than c. The edges connecting the subgraphs to the root node are called gates.

The undirected capacitated arc routing problem consists of demands placed on the edges, and each edge must meet the demand. An example is garbage collection, where each route might require both a garbage collection and a recyclable collection. Problems in real life applications might arise if there are timing issues, such as the case in which certain routes cannot be serviced due to timing or scheduling conflicts, or constraints, such as a limited period of time. The heuristics described in this article ignore any such problems that arise due to application constraints.

Intracellular calcium influx contributes to sperm capacitation and hyperactivation, causing a more violent and rapid non-linear motility pattern as sperm approach the oocyte. The capacitated spermatozoon and the oocyte meet and interact in the ampulla of the fallopian tube. Rheotaxis, thermotaxis and chemotaxis are known mechanisms that guide sperm towards the egg during the final stage of sperm migration. Spermatozoa respond (see Sperm thermotaxis) to the temperature gradient of ~2 °C between the oviduct and the ampulla, and chemotactic gradients of progesterone have been confirmed as the signal emanating from the cumulus oophorus cells surrounding rabbit and human oocytes.

PLOS One 6, e28359. results in delayed transient changes in swimming behavior that involve increased frequency of turns and hyperactivation events. On the basis of these observations and the finding that the level of hyperactivation events is reduced when chemotactically responsive spermatozoa swim in a spatial chemoattractant gradient it was proposed that turns and hyperactivation events are suppressed when capacitated spermatozoa swim up a chemoattractant gradient, and vice versa when they swim down a gradient. In other words, human spermatozoa approach chemoattractants by modulating the frequency of turns and hyperactivation events, similarly to Escherichia coli bacteria.

In mammalian fertilization, hyaluronidase is released by the acrosome of the sperm cell after it has reached the oocyte, by digesting hyaluronan in the corona radiata, thus enabling conception. Gene-targeting studies show that hyaluronidases such as PH20 are not essential for fertilization, although exogenous hyaluronidases can disrupt the cumulus matrix. The majority of mammalian ova are covered in a layer of granulosa cells intertwined in an extracellular matrix that contains a high concentration of hyaluronan. When a capacitated sperm reaches the ovum, it is able to penetrate this layer with the assistance of hyaluronidase enzymes present on the surface of the sperm.

It is recommended that customers should exercise carrier pre-selection and thus be able to switch between service providers. It is also recommended that an organisation be created to manage the local loop and that this organisation should be under the guidance of the regulator Icasa and that Icasa be capacitated in terms of resources. The committee recommended that service providers approved by Icasa should have access to the telephone exchange infrastructure whenever necessary. The committee recommended that a regulatory guideline be established and be managed by Icasa to guarantee that strategic issues like quality of the local loop be optimised for regulation and delivery of services.

The process of capacitation, the maturation period of sperm that is required in order for them to be able to fertilise ova, was also amongst one of Chang's major discoveries. This observation would lead him further to find that capacitated sperm would lose capacitation if exposed to seminal plasma or blood serum, and that recapacitation could be achieved if the sperm was placed back in the uterus or the fallopian tubes. Of all his research and experimentation, Chang's work in in vitro fertilisation was arguably his greatest achievement. In 1935, Gregory Pincus had claimed to have achieved successful mammal birth from the result of in vitro fertilisation of rabbit eggs.

Sperm guidance by either chemotaxis or thermotaxis can potentially be used to obtain sperm populations that are enriched with capacitated spermatozoa for in vitro fertilization procedures. Indeed, sperm populations selected by thermotaxis were recently shown to have much higher DNA integrity and lower chromatin compaction than unselected spermatozoa and, in mice, to give rise to more and better embryos through intracytoplasmic sperm injection (ICSI), doubling the number of successful pregnancies.Pérez-Cerezales, S., Laguna-Barraza, R., Chacón de Castro, A., Jesús Sánchez-Calabuig, M., Cano-Oliva, E., Javier de Castro-Pita, F., Montoro-Buils, L., Pericuesta, E., Fernández-González, R. and Gutiérrez-Adán, A.

Seat of the Ordem dos Engenheiros, Lisbon. A full chartered engineer (Engenheiro) in Portugal used to have a compulsory five-year course known as licenciatura (licentiate) which was granted exclusively by universities. Only engineers having the licenciatura diploma, graduated at the universities, were capacitated to develop any kind of project in engineering and were universally recognized by the Engineers Association of Portugal (Ordem dos Engenheiros). The polytechnic institutions of engineering, born after 1974, used to award the professional title of Engenheiro Técnico (Technical Engineer), a title conferred after a three years course; the degree was known as bacharelato. Polytechnic institutions conferred 3-years bacharelato degrees in several technical engineering specializations, until the late 1990s.

With the bankruptcy of the Penn Central Transportation railroad in 1970, Detroit Edison sought to continue transporting coal from the Monongahela mines in Pennsylvania to a brand new power plant in Monroe, Michigan. However, the bankruptcy of Penn Central left Detroit Edison short of motive power and under capacitated coal hoppers. Detroit Edison then chose to purchase brand new locomotives and coal cars to fit their needs. Purchasing EMD SD40's and GE U30C's for mainline motive power as well as High-Side Articulated Gondolas (with a capacity of 185,000 pounds), this new equipment allowed Detroit Edison to move more coal en masse than what Penn Central was able to do with their equipment.

His recent results include obtaining a 3 approximation algorithm for the capacitated facility location problem. The joint work with Fabian Chudak, has resulted in improving the previous known 5.69 approximation for the same problem. Their algorithm is based on a variant of randomized rounding called the randomized rounding with a backup, since a backup solution is incorporated to correct for the fact that the ordinary randomized rounding rarely generates a feasible solution to the associated set covering problem. For the uncapacitated version of the facility location problem, again in a joint work with Chudak he obtained a (1+2/e) \approx 1.736 -approximation algorithm which was a significant improvement on the previously known approximation guarantees.

This new technological advance has a lot of ethical dilemmas that surround it as it will lead to more exorbitant charges, which will cause a reduction in the amount as well as the types of individuals who may afford the new procedures. There is a concern about if the future generations of natural births will lorded over by a genetically enhanced master class Many issues of reproductive technology have given rise to bioethical issues, since technology often alters the assumptions that lie behind existing systems of sexual and reproductive morality.

The Third Succession Act superseded the First Succession Act (1533) and the Second Succession Act (1536), whose effects had been to declare bastards Henry's daughters Mary and Elizabeth, and to remove them from succession to the throne. This new act returned both Mary and Elizabeth to the line of succession behind Edward, any potential children of Edward, and any potential children of Henry by his then wife, Catherine Parr, or any future wife Henry might have. With the 1536 Act, Henry VIII was authorised to dispose of the Crown by letters patent or by will, in default of any legitimate heirs. Mary and Elizabeth, who had both been declared illegitimate and incapable to inherit, expressly remained so in the 1543/44 Act; they were only capacitated to succeed to the Crown (with several provisos, such as they could not marry without the Privy Council's approval).

Main articles: Labour economics and Contemporary slavery Anarcho-syndicalists and other socialists who criticise wage slavery, e.g. David Ellerman and Carole Pateman, posit that the employment contract is a legal fiction in that it recognises human beings juridically as mere tools or inputs by abdicating responsibility and self-determination, which the critics argue are inalienable. As Ellerman points out, "[t]he employee is legally transformed from being a co-responsible partner to being only an input supplier sharing no legal responsibility for either the input liabilities [costs] or the produced outputs [revenue, profits] of the employer's business.". Such contracts are inherently invalid "since the person remain[s] a de facto fully capacitated adult person with only the contractual role of a non-person" as it is impossible to physically transfer self-determination.. As Pateman argues: According to some law scholars, generally, the contract of employment denotes a relationship of economic dependence and social subordination.
