Our human cell organisation has made evolution of unusual diversity of many frame designs. Many of this design can be traced back to the basic building blocks of tissue which composed of amino acids and endowed with autonomy and adaptation. These cell carries complete genomes sequences which not even required by itself and they are able to grow rapidly and divided after completion of organismic development. The morphogenesis of cell makes it is possible to maintain the structure of the...
Vermicast as organic pond fertilizer can be a good option for pond manuring as they do not pose long term harm to the soil like chemical fertilizer. Organic pond fertilizers used in this study were cattle dung and goat manure vermicasts, raw cattle dung and raw goat manure. This work focused on evaluating the application of vermicast derived from cattle dung and goat manure as fertilizers in fish ponds apart from the correction of pH on Pangasius hypophthalmus aquaculture wastewater. The...
The term Frontotemporal lobar degeneration describes a pathological process that selectively affects the frontal and temporal cortices, while the different clinical syndromes that result from this neurodegenerative process is now often referred to as Frontotemporal Dementia or FTD (Josephs 2008, Seelaar et al. 2011).FTD can be divided in two main groups according to the predominant clinical features at the onset of the disease: a behavioural variant (bv-FTD) characterised by early, prominent...
CHAPTER 1 INTRODUCTION. The continuous rise in waste rubber generated at an alarming proportion from motor car tyres used has become a dilemma. It is estimated that around the world, about a billion tires are dumped up in landfills each year. The recycle of waste tires economically is almost not possible. When burnt, they are harmful to the environment and could also create serious health hazards.The study of these waste materials has been widely carried out for the last twenty years. Waste...
Microbial disinfection using ultraviolet radiation is a world wide technology for drinking water purification. The effectiveness of this technology depends on certain important parameters like the UV intensity, the exposure time, the area, clarity of the water etc. This technology is very convenient and fast, doesn't alter the taste of the water or adding chemicals into the water. The selection of UV wavelength is very important for the efficient disinfection process. The optimum microbial...
The objective of the Pharmacology Lab is to find the lethal chemical(s) or the LD50 relevant to a certain genus. In order for a chemical to be considered the LD50, 50% of the population of the organism present in a container must die. A total of three trials and four tests are completed to determine whether or not the chemical has the ability to kill the brine shrimp. The three trials contain 5mL of the chemical in each container, while the four tests have different amounts of the chemical in...
Field-Cycling NMR relaxometry is a technique for acquiring T1 dispersion curves (a plot of T1 (or relaxation rate R1, where R1 = 1/T1) against magnetic field strength) also known as Nuclear Magnetic Relaxation Dispersion (NMRD) curves. FFC-NMR Relaxometry, has proven to be an invaluable tool in relation to this project, as it allows rapid and accurate determination of the T1 dispersion curves of different contrast agents. This information can be used to select the magnetic field strengths at...
A cell culture grows by the multiplication of cells. The cell cycle occurs to identically copy DNA into two daughter cells. The cell cycle is made up by two basic steps which are interphase and Mitosis. A cell must go through these phases to ensure enough genetic material to produce two identical daughter cells with the same amount of DNA as the mother cell. A cell will spend most of its time in interphase which can be up to 12 hours and much less time in mitosis, about an hour (Alberts et al...
Introduction The Human immunodeficiency virus (HIV) is considered a worldwide pandemic by the World Health Organisation (WHO) with major social and economic consequences. Since its discovery in 1981, HIV has become a burden globally with an estimate of 25 million people being killed to date. (WHO Annual Epidemic HIV Estimates). In terms of epidemiology, the prevalence has increased in people who reside in the Sub Saharan Africa and according to current estimates, HIV is set to infect 23 million...
Influenza A virus is known in the worldwide as an acute contagious viral infectious disease and respiratory tract disease that occur as a result of infection. Flu can cause mild to severe sickness, and can be lethal. Certain people, such as elder people and people with health conditions, are at a high risk for serious problems from the flu virus. The influenza or the flu is caused by RNA viruses which belong to Orthomyxoviridae family of viruses. There are three types of flu viruses infect...
