Adhesion

Cohesion is the attraction of molecules within the same phase while adhesion refers to the attraction of molecules of different phases; say the n-butanol solution and the walls of the capillary tube. If the adhesion force is stronger than the cohesion force, the walls of the capillary tube will be wet, which in turn attracts molecules from the bulk of the solution upward until the pressure…

The acute inflammatory response can be stimulated by an infection, tissue necrosis, foreign bodies, or immune reactions. The stimulus is recognized by receptors on the surface phagocytes, dendritic cells, and epithelial cells. The two types of the receptors are the toll like receptors and the inflammasomes. The toll like receptors recognize bacterial and virus DNA and endotoxins and in response produce inflammatory mediators. The inflammasome recognizes microbial or dead cell products or…

Discovered only recently, the oldest cave painting was found in Spain, believed to be left by the Neanderthals and is now the oldest and historical cave paintings discovered. A previous painting found in France was dated to be from 37,000 years ago, is now replaced by the Spanish cave painting, believed to be more than 48,000 years ago. Now in modern days, paint is very common. There are many different varieties of paints and uses, such as acrylic, water-based, oil-based, sheen, latex, and…

On April 27, 2011, the Court ruled, by a 5–4 margin, that the Federal Arbitration Act of 1925 preempts state laws that prohibit contracts from disallowing class-wide arbitration, such as the law previously upheld by the California Supreme Court in the case of Discover Bank v. Thus, businesses that include arbitration agreements with class action waivers can require consumers to bring claims only in individual arbitrations, rather than in court as part of a class action. In the case of AT&T…

the fragments on to other parts of the cell for other uses. Farber’s disease is a rare, genetic condition that involves a deficiency in the enzyme, ceramidase. Ceramidase is a lysosomal acid that causes cell growth, cellular differentiation, cell adhesion, the movement of cells and the death of cells. The body is unable to produce ceramidase with Farber’s disease, thus causing the buildup of ceramide. A gene is a section of DNA that codes for one protein. When there is a mistake in the…

approximately 1.5 MPa, while its shear strength (defined as the ability of an object to withstand forces that would cause the internal structure of the object to slide against itself) is approximately 2.5 MPa in wet conditions. SRT also exhibits good adhesion strength to various substrates. SRT protein can also be easily shaped: the protein is a pressure sensitive adhesive (PSA) that, once melted, is plasticized by water above 32 degrees Celsius. Its ability to be melted and then cooled back to…

Carpal Tunnel Syndrome is a condition in which the space within the carpal tunnel in your wrist is reduced and the median nerve, one of the major nerves in your hand, is pinched as it travels through the tunnel. Injury, fractures, rheumatoid arthritis, work stress, repetitive use of hand tools, and things such as factory work, gardening, or typing over a long period of time, are typical causes of Carpal Tunnel Syndrome. If your job makes your carpal tunnel worse, doctors often recommend a…

RMW is a common complication of neuromuscular diseases. It causes a respiratory failure which may lead to death (Bourke, 2014). RMW can be classified as acute (as seen in Guillain-Barré syndrome), chronic and relapsing (relapse) (as seen in multiple sclerosis, myasthenia gravis), or relentlessly progressive (as seen in amyotrophic lateral sclerosis [ALS]) (Ambrosino, Carpene, & Gherardi, 2009; Areeyapinan & Phanthumchinda, 2010; Berrih-Aknin, Frenkian-Cuvelier, & Eymard, 2014). Assessment and…

Over an eight year period from the years 2005 through 2013 more than eight thousand individuals have been diagnosed with cat scratch disease (cdc.gov). Evidence of some symptoms individuals would develop when they would contract this illness was first notified back in the 1950’s, but the disease causing agent wasn’t identified until the mid-1980’s. Even though this disease has not been proven to cause death amongst its victims it is still important to understand some key factors to be aware of…
