That said, the process did require a certain amount of acumen; for this process to come about, Neanderthals needed to recognize certain material properties, such as the degree of adhesiveness and viscosity.

Whitman's homosexuality became unmistakable in his impassioned "Calamus" poems of "adhesiveness," named for a plant with phallus-shaped "pink-tinged roots," but, even before then, his sensuality, regarding women as well as men, was earthy enough to rattle the genteel.

Adhesiveness depends not only on the type of tape but also on its macroscopic shape. Tapes with sharp corners start to detach at pointed corners. Adhesive strength can be improved by rounding the corners.

Platelet adhesiveness is the adhesion of platelets to other structures. It can be contrasted with platelet aggregation, which refers to the processes or factors which lead to the adhesion of platelets to other platelets.

In 1989 he published the poetry collection These Waves of Dying Friends.Judith Lawrence Pastore, Confronting AIDS Through Literature: The Responsibilities of Representation. University of Illinois Press, 1993. . At the time of his death, he had an unfinished gay studies manuscript, The Age of Adhesiveness: From Friendship to Homosexuality, in development.

Hybrid wood Wood hybrid profiles are obtained through extrusion. The wood composite covers a core in anodized aluminum core. The optimal adhesiveness between these two materials is made possible by applying a coextruded intermediate adhesive layer. The wood composite layer can be applied on only one side of the profile if so required.

Impaired platelet aggregation is an uncommon consequence of chronic hypoglycemia, seen in GSD I patients. Research has demonstrated decreased platelet function, characterized by decreased prothrombin consumption, abnormal aggregation reactions, prolonged bleeding time, and low platelet adhesiveness. Severity of platelet dysfunction typically correlates with clinical condition, with the most severe cases correlating with lactic acidosis and severely lipidemia. It may cause clinically significant bleeding, especially epistaxis.

The density decreases up to a comonomer share of 10% because of the disturbed crystal formation. With higher proportions it approaches to the one of polyvinyl acetate (1.17 g/cm3). Due to decreasing crystallinity ethylene vinyl acetate copolymers are getting softer with increasing comonomer content. The polar side groups change the chemical properties significantly (compared to polyethylene): weather resistance, adhesiveness and weldability rise with comonomer content, while the chemical resistance decreases.

These agents are used commonly by microsurgeons to decrease vascular thrombosis. The antithrombotic effect of dextran is mediated through its binding of erythrocytes, platelets, and vascular endothelium, increasing their electronegativity and thus reducing erythrocyte aggregation and platelet adhesiveness. Dextrans also reduce factor VIII-Ag Von Willebrand factor, thereby decreasing platelet function. Clots formed after administration of dextrans are more easily lysed due to an altered thrombus structure (more evenly distributed platelets with coarser fibrin).

The nonlinear response of smart polymers is what makes them so unique and effective. A significant change in structure and properties can be induced by a very small stimulus. Once that change occurs, there is no further change, meaning a predictable all-or-nothing response occurs, with complete uniformity throughout the polymer. Smart polymers may change conformation, adhesiveness or water retention properties, due to slight changes in pH, ionic strength, temperature or other triggers.

Water droplets are flatter on a Hibiscus flower which shows better adhesion. In surface science, the term adhesion almost always refers to dispersive adhesion. In a typical solid- liquid-gas system (such as a drop of liquid on a solid surrounded by air) the contact angle is used to evaluate adhesiveness indirectly, while a Centrifugal Adhesion Balance allows for direct quantitative adhesion measurements. Generally, cases where the contact angle is low are considered of higher adhesion per unit area.

It provided the European peace the nations sought, and would evolve into the European Union seen today. It was not a new concept as trade has historically been viewed as a catalyst for peace between nations. Creating multi-level governance is shown to create the necessary ties for fostering economic interdependence to a greater degree than mere trade between nations. The linking of nations through a sharing of capital creates an adhesiveness that deters the escalation of political conflict from reaching a state of war.

As the skeleton forms the structure of the body, it is vital that it maintains its strength, even after breaks and injuries. Collagen is used in bone grafting as it has a triple helical structure, making it a very strong molecule. It is ideal for use in bones, as it does not compromise the structural integrity of the skeleton. The triple helical structure of collagen prevents it from being broken down by enzymes, it enables adhesiveness of cells and it is important for the proper assembly of the extracellular matrix.

To this day, only coextrusion at high temperature of a powerful adhesive and of composite wood allows the "fusion" of 2 materials as different as aluminum and composite wood. This adhesiveness is so powerful that bending the profiles is possible even at very low radii, thus broadening significantly the fields of applications. In the construction, decoration or design industry sector, hybrid woods have the look, feel and sometimes smell of natural wood. They are easier to install and better performing than natural wood and their exceptional properties allow utilizations that are many times broader than those of wood.

An inkometer is a specialized measuring instrument used by the printing industry to measure the "tack" (adhesiveness) of an ink with the roller system on an offset press. The importance of tack is that it is not so excessive that it doesn't allow effective transfer from the rollers to the plate and then to the blanket and onto the substrate being printed. Inks can also be tack "graded" in descending sequence to allow for better trapping of one color over another. Inks with too much tack can cause the surface of the paper to pick off and interfere with transfer on subsequent printing units and copies.

These factors play a direct role in inducing the epithelial-mesenchymal transition by reducing expression of occludin and N-Cadherin in addition to promoting modification of NCAMs with polysialic acid residues to decrease adhesiveness. Neural crest cells also begin expressing proteases capable of degrading cadherins such as ADAM10 and secreting matrix metalloproteinases (MMPs) that degrade the overlying basal lamina of the neural tube to allow neural crest cells to escape. Additionally, neural crest cells begin expressing integrins that associate with extracellular matrix proteins, including collagen, fibronectin, and laminin, during migration. Once the basal lamina becomes permeable the neural crest cells can begin migrating throughout the embryo.

CSGAGs interact with heparin binding proteins, specifically dermatan sulfate interactions with fibroblast growth factor FGF-2 and FGF-7 have been implicated in cellular proliferation and wound repair while interactions with hepatic growth factor/scatter factor (HGF/SF) activate the HGF/SF signaling pathway (c-Met) through its receptor. CASGAGs are important in providing support and adhesiveness in bone, skin, and cartilage. Other biological functions for which CSGAGs are known to play critical functions in include inhibition of axonal growth and regeneration in CNS development, roles in brain development, neuritogenic activity, and pathogen infection. ;Keratan sulfates:One of the main functions of the third class of GAGs, keratan sulfates, is the maintenance of tissue hydration.

He was also an innovative writer of guidebooks to climbing venues such as Lliwedd and Tryfan. Edwards' climbing style was described by Geoffrey Winthrop Young as "serpentine and as powerful as an anaconda coiling up loose or wet overhangs, I had the conviction that human adhesiveness in movement could go no further". He was happier climbing overhangs and loose rock than his contemporaries and predecessors, meaning he could pioneer climbs in new areas. He made more than a hundred first ascents, most of them in Snowdonia and including many of the now-classic rock routes on the crags of the Llanberis Pass in Snowdonia such as Flying Buttress, Spiral Stairs, Crackstone Rib, Nea and Brant.

The Nobel laureate, Bengt I. Samuelsson, and colleagues first described 5(S)-HETE in 1976 as a metabolite of arachidonic acid made by rabbit neutrophils. Biological activity was linked to it several years later when it was found to stimulate human neutrophil rises in cytosolic calcium, chemotaxis, and increases in their cell surface adhesiveness as indicated by their aggregation to each other. Since a previously discovered arachidonic acid metabolite made by neutrophils, leukotriene B4 (LTB4), also stimulates human neutrophil calcium rises, chemotaxis, and auto-aggregation and is structurally similar to 5(S)-HETE in being a 5-(S)-hydroxy-eicosateraenoate, it was assumed that 5-(S)-HETE stimulated cells through the same cell surface receptors as those used by (LTB4) viz., the leukotriene B4 receptors.

Haemoglobin C is common in malarious areas of West Africa, especially in Burkina Faso. In a large case–control study performed in Burkina Faso on 4,348 Mossi subjects, that HbC was associated with a 29% reduction in risk of clinical malaria in HbAC heterozygotes and of 93% in HbCC homozygotes. HbC represents a ‘slow but gratis’ genetic adaptation to malaria through a transient polymorphism, compared to the polycentric ‘quick but costly’ adaptation through balanced polymorphism of HbS. HbC modifies the quantity and distribution of the variant antigen P. falciparum erythrocyte membrane protein 1 (PfEMP1) on the infected red blood cell surface and the modified display of malaria surface proteins reduces parasite adhesiveness (thereby avoiding clearance by the spleen) and can reduce the risk of severe disease.

1-Vinylimidazole is used because of its high reactivity for free-radical (UV) polymerization as reactive diluent in UV lacquers, inks and adhesives for coatings and lacquers. It is also used for the functionalization of polymer surfaces by UV-induced grafting to improve wettability and adhesiveness. 1-Vinylimidazole can be quaternized with n-alkyl iodides to 3-n-alkyl-1-vinylimidazolium iodides or with dimethylsulfate to 3-methyl-1-vinylimidazolium methosulfate. The resulting quaternary ammonium compounds can be free-radically polymerized in aqueous solution with the water-soluble azo initiator 4,4'-azobisvaleric acid. Polymerisation von quartären 1-Vinylimidazoliumverbindungen Copolymers of quaternary N-vinylimidazolium salts and polar monomers (in particular N-vinylpyrrolidone) are cationic polyelectrolytes and are suitable, inter alia, as flocculants for water treatment, as flotation auxiliaries for coal and ore processing, as additives for drilling fluids and cementations in the extraction of oil, as emulsion cleavers for the dewatering of crude oil emulsions in refineries, and as corrosion inhibitors for iron alloys.
