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
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
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
routine circumcision.” (n.d.). Since circumcision has so many risks, I would not recommend circumcision for my patients. Some risks include bleeding, pain, infection, excess loss of skin, redundant foreskin resulting in circumcision revision, penile adhesions, meatitis/meatal stenosis, urethrocutaneous fistula, glanular necrosis/glanular amputation
directly borrow solutions from l... ... middle of paper ... ... Lotus effect is just one of the many demonstrations of Biomimetic. Other possible realms of the applications include 1. The Gecko effect- when strong adhesion is needed (e.g., adhesive tapes) or for reversible adhesion (e.g., climbing robot); 2. Fish Scales- ecological coatings ; Underwater oleophobicity - self-cleaning and antifouling surfaces; 3. Moth eye effect- the self-cleaning ability combined with optical properties; 4. MicroElectroMechanical
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
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
warmed up through effleurage strokes and any adhesions have been identified, deeper strokes such as friction or vibration can then be applied. Direction The choices of direction are longitudinal, transverse and circular. Each
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
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
Endometriosis is one of the most common gynecological disorders which affect 5.5 million women in the U.S. and 176 million women worldwide. It is a chronic disorder found within the pelvic area of women. This disease is found to affect women of all ethnic and social backgrounds. While it has not yet been determines exactly what causes endometriosis there seems to be certain trends that may contribute to this disease. There also seems to be a link this being a hereditary disease. Symptoms can vary
Díaz. Is it any preference between in office treatment or high-adhesion whitening strip? Are there any side effects of either treatment? Outcome of interest: I hope this treatment plan help with the whitening of Mr. Díaz’s teeth. I also plan on educate him about how to avoid future discoloration of the teeth. In order
Dental plaque is a bacterial collection with their products on the teeth or other solid oral structures, covered by a jelly-like tenacious material and it is responsible for two major dental diseases; caries and periodontal disease (Chandra, 2000). Good oral hygiene is a foundation step in the development of disease-free oral cavity of infants through adolescents (Srivastava, 2011). Plaque control is of prime importance for the prevention of these diseases and for good dental health as it helps to
Endometriosis is a very painful disorder that effects the tissues that lines the inside of the uterus. Endometriosis causes the tissue to grow outside your uterus. Endometriosis usually involves your ovaries, bowel or the tissue lining your pelvis. Rarely, does the tissue spread beyond your pelvic region. Many researchers have tried to find a cause for this disease but to this day the cause is still unknown. There is no cure for endometriosis, however there are several treatments for the symptoms
The immunologic events that are happening at the local level during Carlton's acute inflammatory response would be: Margination and adhesion to the endothelium, in which accumulation of leukocytes occurs along the endothelial wall for adhesion. Afterward, these adhesions cause the separation of endothelial cells, allowing the leukocytes to extend and Transmigrate through the vessel walls. Followed by the response of chemical mediators(chemotaxis) that
Introduction To understand the human gut health and aetiology, the first step is to understand the gastrointestinal (GI) microflora and its distribution through the digestive system [2]. The human GI tract is inhabited by trillions of microorganisms, which together is known as the microbiota [5]. These microorganisms come from both archeal and bacterial domains. Bacteria are the predominant kingdom of organisms and it is composed mainly by five bacterial phyla: Firmicutes, Bacteroidetes, Actinobacteria
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
Atherosclerosis is a pathological condition that underlies several important adverse vascular events such as stroke, cerebrovascular disease, Coronary Artery Disease (CAD). etc. [1]. It is responsible for most of the cardiovascular morbidity and mortality in the Western World currently [2]. As a result of the adoption of the western life style, its prevalence is increasing all over the world and could likely reach epidemic status in the coming future [2]. Atherosclerosis is a chronic disease of the
