Tetanus, also known as lockjaw, is an acute and potentially life-threatening infection caused by toxins released from the bacteria Clostridium tetani. It is commonly found in soil, fecal matter and dust in areas that tend to by hot and humid. The bacteria enter the body through open wounds or cuts, causing bacterial infection in those that have not been vaccinated or have not received the proper vaccination. Tdap should be administered in three doses during normal childhood vaccinations and it…

periodically for the sexual development i.e perfect state. Mating can be observed by seeing the dense filament growth surrounding the colony and is confimed by observing dikaryotic filaments, clamp connections, basidia and chain of basidiospore under light microscope as compatible mating type (Wicks BL et al, 1996; Halliday CL et al, 1999) or stereoscope Niko- SZ-PT (Ohkusu M et al, 2002). Slide Mating Methd (Fraser JA et al, 2003):- In this method a sterile glass slide is placed in a sterile…

They used a CAT scan to calculate brain volume, eye size, and different spots on the teeth. Scientists also used scanning electron microscopes to photograph the fossil’s teeth. It was determined that these monkeys were fruit/leaf eaters like most tropical monkeys. Scientists also studied the hominid’s DNA. The average number of chromosomes a monkey has is 42 to 54. The number of chromosomes…

INTRODUCTION: Exercise 3.1 - Osmosis: Toward the start of lab, we found out about diffusion which can happen as active transport or passive transport. Diffusion is known as delivering a net development of solute particles from locales of higher focus to districts of lower concentration. Active transport is the development of an atom over the plasma layer. Active transport is when atoms move against their focus slopes. We discovered that dynamic transport requires vitality, and the motivation…

What are the nonpolar parts of a phospholipid? c. Tail group 4. This is the only polar portion of a cholesterol molecule and it forms hydrogen bonds with the polar heads of phospholipids. d. –OH group 5. This type of membrane protein will extend throughout the entire membrane touching both the Intracellular fluid and the Extracellular fluid. e. Integral proteins f. Transmembrane proteins g. Integral proteins and Transmembrane proteins Ans: D…

Abstract. In this work investigation for the effect of compressed CO2 on the morphology of the produced Polyaniline (PANI) was carried out. The conventional oxidative polymerization using ammonium peroxydisulfate as oxidizing agent was used with and without compressed CO2. The results showed that different morphologies of PANI nanorods and PANI nanoparticles were produced using the conventional polymerization with and without compressed CO2 respectively. Molecular characterization of the…

Introduction A common question/theme within the mathematics department that keeps reappearing time and time again is, "when am I ever going to use this" or "when is this going to be useful to me". Even I can say that the same thoughts had crossed my mind when studying surds in year seven. This can be a frustrating sticking point for both students and teachers alike. Consequently more questions have arisen from this such as: are certain topics too abstract? Has the application of mathematics…

The plasma membrane also known as the cell membrane is found in every cell. The cell membrane is around 7-10nm, making it difficult to view even with a transmission scanning electron microscope (it only shows a double black line), this means that no one knows exactly what the membrane looks like. All membranes have the same basic structure made up from phospholipids (fats). The membrane is made up of a phospholipid bilayer; consisting of a polar phosphate head and two fatty acid tails. The head…

direction. As natural material, the shale rock samples are not homogenous, so for each sample, at least 12 tests are done on the sample and averaged to get a result to be statistically correct. The indentation points are chosen carefully using the microscope before each test with the setting conditions shown in table above. Figure below shows the example of the shale sample, indentation line profile and single indentation mark on the sample surface Figure 2: Example of…

Oftentimes, knowledge about the background of authors can lead to a deeper and more thorough understanding of their work. Erin L. McCullough is a Postdoctoral Research Fellow at the Centre for Evolutionary Biology at the University of Western Australia (cite- https://www.researchgate.net/profile/Erin_Mccullough2). She was a PhD student at the University of Montana and has a recently updated blog in which her most recent papers and publications can be found (https://erinlouisamccullough.wordpress…
