1.1 Caenorhabditis elegans (C. elegans) Caenorhabditis elegans is a free-living non-parasitic, non-infectious, non-pathogenic, transparent Nematode (roundworm). It has a full grown length of about 1mm, a life span of around 3 weeks and is found in temperate soil environments where it survives by feeding on microbes such as bacteria. [1] Consisting of about 1000 somatic cells as an adult, C. elegans is amenable to genetic crosses and produces a large number of progeny, at times even…

The first virophage to be discovered is Sputnik virophage. It was found accidentally while examining Mamavirus with an electron microscope. The Acanthamoeba that contained Mamavirus was found in a water cooling tower in Paris. Sputnik depends upon the co-infection of host cells by larger viruses known as Mamavirus and alone is incapable of infecting the host amoeba cell [9]. A…

concentration of iron is low. Whenever the concentration is low, it would show fluorescent pigments under UV light. Although this unknown was tested negative for the presence of nitrate reductase, there are certain strains that uses nitrate as the terminal electron…

concentration of metal precursor, contact time and solution pH on the formation of AuNPs was evaluated to determine the optimum conditions for synthesis. As synthesized AuNPs were characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray analysis…

Pox virus is a double DNA virus that is best characterized by lesions that appear on the skin. The virus is identified using an electron microscope to find the brick shaped virions (King 2012). The use of Polymerase Chain Reaction (PCR) can identify which subfamily and genus the strand of pox virus is classified under. The family Poxviridae can be split into two subfamilies Chordopoxvirinae (vertebrate pox virus) and Entomopoxvirinae (insect pox virus) (Bracht et al 2005, King 2012). The…

Sulfamethazine remediation potential of Arabidopsis thaliana root ABSTRACT The use of antibiotics in animals either as a growth promoting or as a disease treating agent has become a worldwide trend. Antibiotics being stable bioactive compounds are not fully absorbed into the animal system and are released into the environment through animal manure. This study aims to discern the effect of one such veterinary antibiotic, sulfamethazine, on Arabidopsis thaliana root and also the possible…

There are many instances in my life during which I thought to myself “this is why I want to become a doctor.” However, there are only a few moments where I have thought to myself “this is why I will become a doctor.” Since I was a little girl, I have always wanted to become a doctor. Although I cannot pinpoint the exact time when this idea was born, I can say that it has stuck with me for a majority of my life. While shadowing at hospitals and physical therapy clinics, I always felt that…

Finding efficient methods of heavy metals from a contaminated water source is crucial for achieving clean drinking water. Heavy metals tend to accumulate in living organisms and cause health disorders and diseases3, 7, 11. Unlike organic contaminates, heavy metals do not degrade and therefore are not easily removed from the water system. For this reason, most large-scale water treatment facilities rely on coagulation to chemically precipitate metals from the source water and by sieve…

So the need for imaging system that covers almost the entire EM spectrum is raised. Imaging systems are physical device that generate image from source that mostly are not within human visual band, including video camera, x-ray devices, electron microscopes, radar, ultrasound, ... etc. A digital image is a representation of a two-dimensional image using ones and zeros (binary). It may be of vector or raster type. Without qualifications, the term "digital image" usually refers to raster…

In recent years, modern Li-ion batteries (LIBs) have become ubiquitous power source for a variety of applications such as laptops, mobile phone, and digital camera to electric vehicles, owing to their high power density, high energy density, and long cycle life.1–3 However, there are still many critical challenge to increasing the energy, power density, and improved cycling stability.4–6 In particular, selecting noble electrode materials is the hottest topics in the LIB field. Among them, bulk…
