I. Introduction A journey to space is a journey expediting the unknown. A road that no one knows what to expect or what is about to happen. I was really fascinated by one of the most debated as well one of the least known phenomena called black hole. Black hole is place in space where … Read more
1.Review of J. Phys. Chem., 1986, 90, 2555-2560 This paper mainly focuses on the experimental and theoretical background of properties, which differ in nanoparticles from the bulk material. This change depends on the size in semi conductor crystallites of ~15Å to several hundred angstroms. The “crystallites” are named as clusters. Generally, the word ‘nanocluster’ is … Read more
Despite the ubiquitous presence of P. acnes on human tissues, concrete knowledge in relation to its pathogenic role amongst various disease states remains controversial (Portillo et al. 2013). Numerous studies have indicated the organisms’ ability to act as an opportunistic pathogen, with suggested etiological roles amongst a number of inflammatory diseases such as acne vulgaris … Read more

The Internship Programme is also important in the development and growth of the student, as well to attest to the capabilities of any graduate in a professional background. Overall the Internship … Read more
Abstract: Among the possible methods for the determination of elements is flame photometry which is a type of atomic spectroscopy whereby a sample is introduced into a flame and undergoes various processes, this leads to the formation of excited atomic species that emit radiation. This method of analysis is suitable for both the qualitative and … Read more
Introduction Granulation is a process of forming or crystalizing powders into grains. It is a process in which primary powder particles are compressed to bind and form multi-particle entities that are known as granules. In the process of granulation, particles are collected together by compressing the particles and this causes them to form bonds between … Read more
Specific Aims The overall goal of this proposal is to investigate the mechanism of virus-mediated formation of double membrane vesicles within the endoplasmic reticulum (ER). The ER is considered the origin of induced intracellular structures for a number of viruses.1 It has been shown that the formation of double-membrane vesicles (DMVs) within the ER is … Read more
Genetics is the study of genes and heredity explaining how certain traits is passed on from parents to their offspring which is as a result of changes in the DNA sequence. A gene is a part of a DNA, it contains the instructions of building molecules and how they should work. Genome on the other … Read more
Abstract Estrous cycle is a physiological change in female individuals that associate with reproduction including rats. It has four stages categorized as proestrus, estrus, metestrus and diestrus. Rats are an ideal animal for investigation of changes occurring during the reproductive cycle due to its short cycle length. The estrous cycle in rats lasts averagely in … Read more
Abstract In this project I intend to explore to what extent ethical arguments about the research on Embryonic stem cells (ESC’s) and induced pluripotent stem cells (IPSC’s) have changed over the last 20 years and how factors such as, breakthroughs in research, socioeconomic and government involvement and widening access to media have contributed to these … Read more
Mohebbi et al. (2012) studied in his research, the effects of Aloe vera, gum tragacanth, and combination of both as edible coatings on the shelf life and postharvest losses of mushrooms. Physical characteristics were evaluated during storage. Mushrooms were stored at 4, 10, and 15 ”C for 13 days and physicochemical characteristics were analyzed after … Read more
Life cycle assessment of germinated oil palm seeds production and oil palm seedling production employing an open-source software 1.1. Abstract Palm oil sustainability is very dependent on identifying the impacts from the activities of the smallholder farmers, as smallholder farmers the major producers of the world’s palm oil. Employing a scientifically acceptable and free cost … Read more
New UV-curable prepolymer, 2–hydroxy–3–[p–(1–{2–hydroxy–3–(isoprophenylcarbonyl- oxypropoxy)phenyl}methylcyclohexyl)phenoxy]propyl acrylate (BISCHDA) was synthesized by the reaction of p–[1–(p–hydroxyphenyl) methylcyclohexyl] phenol with methylcyclohexanone, epoxidation with epichlorohydrin followed by addition reaction with acrylic acid. All synthesized compounds were characterized by 1H-NMR, 13C-NMR and FT-IR spectroscopy. Several UV-curable formulated solutions were prepared separately by mixing the prepolymer, BISCHDA (75%), diluent, tri (ethylene … Read more
Introduction For centuries, humankind has been looking at the stars and wondering whether a world like ours could exist in the vastness of space. Our search has been stirred in recent years with the discovery of the first extrasolar planets, which proved that the galaxy is populated by billions of other worlds. We now have … Read more
