    After watching a herd of buffalo respond to a crisis on a video segment called "The Battle at Kruger,” I realized group cohesion was perfectly illustrated by a herd of buffalo. In the video, the buffalo are grazing in a field. Lying in wait is a pride of lions. As with most predatory species, the lions look for the best opportunity for food. When the buffaloes first happen upon the lions, their initial instinct is to scatter or respond individually. That’s when the baby buffalo becomes vulnerable

    shape and adhesion; as well as identify the molecules necessary for cytoskeleton function. There were two experiments preformed, one involving RAW cells and the second involving rabbit skeletal muscle cells. The first experiment required the RAW cells to be exposed to different concentrations of the drug cytochalasin D. This particular drug inhibits the polymerization actin, a protein microfilament involved in the cytoskeleton. It provides shape to cell and is involved in cell adhesion. After incubation

  • Endothelial Cells Essay

    expressed by the inflamed endothelial cells, causing increased adhesion susceptibility , tissue necrosis, inflammation and vegetation growth. In conclusion, endothelial cells in atherosclerosis causes the increased expression of surface adhesion molecules which results in the increased amount of leukocytes attracted to the site and thus causing more inflammation than usual. In infective endocarditis, NBTE allows bacterial adhesion of the heart valves, mediated by ClfA and then FnbpA. These causes

  • Primer Paint Case Study

    787 Words  | 2 Pages

    Introduction Primer paint is used to improve paint adhesion. At ZMD, an aerospace company manufacturing commercial aircrafts, primer paints are applied to several aircraft components. ZMD’s Aircraft_Series_900 design specifications calls for a primer paint, with a minimum adhesion force of 4.0N. As a process engineer at ZMD, I am conducting this study to identify areas of opportunities for quality improvement. For this purpose, I have taken the initiative in researching the alternative brands to

  • Importance Of Interpenetration

    1041 Words  | 3 Pages

    Diffusion theory: Diffusion theory describes the interpenetration of both polymer and mucin chains to a sufficient depth to create a semi-permanent adhesive bond. The adhesion force increases with the degree of penetration of the polymer chains. This penetration rate depends on the diffusion coefficient, flexibility and nature of the mucoadhesive chains, mobility and contact time. The depth of interpenetration required to produce an efficient bioadhesive bond lies in the range 0.2-0.5 μm. This interpenetration

  • Pros And Cons Of Circumcision

    760 Words  | 2 Pages

    Penile adhesions often result from inadequate lysis of natural adhesions prior to circumcision or from migration of the skin from a prominent suprapubic fat pad. “The majority of these adhesions should lyse spontaneously as the penis grows, suprapubic fat recedes, and erections become more frequent and firmer” (2011). Otherwise, lysis of penile adhesions can be performed in the doctor’s office if they don’t lyse naturally on their own. This is accomplished by gently pushing away the adhesions from

    important to the denture retention to have less salivary glands Physical factors : Adhesion: It is the physical attraction of unlike molecule to one another. The ionic force between charged salivary glycoprotein and surface epithelium or acrylic resin will lead to the adhesion .and the closeness of adaptation to oral mucosa will increase the denture adhesion. With less contact angle there is more adhesion. Also adhesion depend on the viscosity of saliva because the wetting of the saliva on the denture

    signaling and their role in maintaining the epidermis (Sudbrak et al. 1). The gene encodes a protein that acts as a calcium pump in cells. This protein pumps calcium ions into the lumen of the Golgi apparatus. Calcium ions are vital in cell-to-cell adhesion processes and differentiation, and if the calcium pump does not function properly, the affected cells will not stick together, thus causing damage to the skin (Szigeti 1). The protein encoded by ATP2C1 has the same transmembrane organization, including

  • Tribology Essay

    There are many attributes that affect the properties of a composite material, based on their intrinsic properties of the constituents. The properties that are harnessed to reinforce a composite material are essentially governed by the similar factors that affect other fiber composite materials, namely the fiber architecture and the fiber–matrix interface. Fiber architecture of composite properties usually revolves around the fiber geometry, packing arrangement, fiber orientation, and fiber volume fraction

  • Cohesion Of Water Essay

    1086 Words  | 3 Pages

    There are several characteristics that water possesses that are essential to life on Earth. Four of them are cohesion and adhesion, ability to moderate temperature, expansion upon freezing, and versatility as a solvent. The first part, cohesion, is the attraction between molecules of the same kind. Water molecules have strong cohesive behavior because they have the ability to form hydrogen bonds with each other. Cohesive behavior is what is responsible for surface tension, which is when stress or
