Explanation of a microbiological algorithm for Hospital-acquired and Ventilator associated pneumonia. This algorithm is intended to deal with the microbiological aspects of hospital-acquired and ventilator-associated pneumonia. The severity of the illness is important in determining when to collect the diagnostic samples and which antimicrobials to administer due to which organisms are present. There are many prognostic scoring systems used to suggest the severity of the disease in patients…

The Critical Noncarcinogenic effect of acrylamide is classified as “Degenerative Nerve Changes”. This means that chronic ingestion of acrylamide resulted in an observable damaging of the central and peripheral nervous system, thus classifying it as a neurotoxin. This conclusion was determined after the results of two separate chronic (2year) drinking water studies performed on lab rats. (Friedman et al., 1995, 224307; Johnson et 14 al., 1986, 061340). The doseresponse data for acrylamide was…

2.1. Na-ion Batteries (NIBs) Na-based batteries are not new. Back to the 1970s, Na-ion and Li-ion batteries were investigated in parallel.5,6 The investigation of Na-ion batteries significantly decreased after the success of commercial application of Li-ion batteries in the 1990s. Na-ion batteries have a very similar working principle as the Li-ion batteries. As shown in Figure 2.1, each electrochemical cell is basically composed of a positive electrode, a negative electrode, and a membrane…

In order to determine the sequence of events that occurred at a crime scene it is important to be able to determine and identify certain bodily fluids versus non-human substances. Based on the location of the biological evidence and its DNA can provide crucial information about the crime scene, its victim, and the suspect(s). These tests divided between presumptive and confirmatory testing. Blood evidence is the most common type bodily fluid found at a crime scene. Presumptive testing at the…

Slide Two- Aerobic Metabolism Metabolism is vital to the body, as it converts proteins, carbohydrates and fats into energy. Aerobic metabolism requires oxygen to function, unlike anaerobic metabolism (Tang, nd). The oxygen breaks down glucose to release energy in the form of ATP, producing carbon dioxide and water as bi-products. The process of aerobic metabolism includes glycolysis, the citric acid cycle, Krebs cycle and the electron transport chain (Pass My Exams, nd). Slide Three- Pyruvate…

result of his test shown that stone was about 500 years old. In addition, the analyses of Wolter announced and confirmed the stone is genuine. Scott F. Wolter is a university-trained, certified geologist. He used photography with reflected light microscopy, core sampling, and scanning electron microscope scanning to analyze the stone. In November, he presented his early findings: the works shown that the stone has unclear signs of a surface erosion process requiring a minimum of 200 years…

Cellular Theory & Microscopes Robert Hooke Robert Hooke was an English scientist credited most famously for the creation of Hooke’s Law (a principle of physics that states that the force needed to extend or compress a spring by some distance is proportional to that distance) in 1660 and the discovery of plant cells using a compound microscope in 1663. The compound microscope uses two or more lenses, which are connected by a hollow tube. The top lens (called the eyepiece) is the one that people…

whose parents are farmers, had the highest prevalence of Plasmodium falciparum infection. Children from Afegame and Davanu primary schools had the highest prevalence of Plasmodium falciparum infection with 75% and 52% for RDT and 59% and 46% for microscopy…

Coral Reef Bleaching Coral reef bleaching, which is the whitening of diverse invertebrate taxa. The cause of the whitening is “from the loss of symbiotic zooxanthellae and/or a reduction in photosynthetic pigment concentrations in zooxanthellae residing within the gastrodermal tissues of host animals.” (P.W.Glynn) The reason why coral reef bleaching is such a concern is because the “consequences of bleaching large numbers of reef-building scleractinian corals and hydrocorals.”(P.W.Glynn)…

PERIODONTOLOGY LLLT stimulates fibroblasts for faster regeneration of soft tissue, while providing analgesia and a modulation of the inflammatory chemicals that cause pain and discomfort. LLLT when used in conjunction with surgical lasers for treatment such as gingivectomy, periodontitis and periodontal surgery, have shown great promise in achieving improved clinical outcomes. A 2006 study12 showed a statistically significant decrease in pocket depth at 21 and 28 days postsurgery. Moreover,…
