Introduction At the global level, the rapid growth in motor vehicle activity has serious energy security and climate change effects. The transport sector already customer nearly half of the world’s oil. But in urban areas – both developing and developed countries, it is mainly mobile or vehicular pollution that contributes to air quality problem. The … Read more
Assisted reproductive technologies are often viewed as ‘threatening the moral fabric of society as a whole’ (MARCIA INHORN). DISCUSS, with examples, how the political and legal systems of different nation states have responded to this ‘threat’. Introduction With any biotechnology, acceptance within both the public and authoritative spheres is crucial to its widespread use and … 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
Identification of Atg11p binding-partners involved in macropexophagy in the methylotrophic yeast Hansenula polymorpha Subtitle Determination and identification of unknown binding partners of atg11p involved in peroxisome degradation Abstract Defects in peroxisome biogenesis can cause degradation of peroxisomes that can lead to severe diseases in man that in some cases are lethal like the Zellweger syndrome. … 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
ABSTRACT: Biomedical telecommunication permits the transfer of information from one body to off the body or from on the body to on the body. Patch antennas and its different variations as implantable medical devices are one of the highest, particularly in receiving attention for scientific interest in integrating these implanted devices and radio frequency enabled … Read more
CHAPTER 1. INTRODUCTION Chemical industry have no doubt brought development but has also left with the environmental problems also. Traditionally, waste is viewed as an unnecessary element arising from the activities of any industry. In reality, waste is a misplaced resource, existing at a wrong place at a wrong time. Waste is also the inefficient … Read more
ABSTRACT: In recent years, iron oxide nanoparticles (NPs) have pulled much attention in research field, due to their unique and special properties, such as superparamagnetism, surface-to-volume ratio, easy separation processes and greater surface area. This paper focuses on the synthesis, characterization and various applications of iron oxide nanoparticles. There are several physical, chemical, and biological … Read more
1.Introduction Bacillus anthracis is the etiological agent of anthrax; a common disease of livestock and, occasionally, of humans. It can be grown ordinary nutrient medium. Genus bacillus have only Bacillus anthracis as a obligate pathogen, Bacillus anthracis is a Gram-Positive bacteria, and it is also an endospore forming bacteria. It is road-shaped with a width … Read more
Abstract: Salmonella, among other Gram-negative bacteria, possess a molecular syringe-like apparatus known as a type III secretion system (T3SS). T3SSs are virulence factors utilized by the bacterium to increase pathogenicity and to evade host immune processes that could potentially be harmful to the bacterial cell. The T3SS is expressed once Salmonella comes into contact with … Read more
1.0 Introduction This report covers lab 5 of the Engineering Materials unit, dedicated to metallography and heat treatment. The lab expands on concepts covered in lectures including heat treatment, crystal structure of metals, and mechanical properties of materials by introducing them in a hands-on environment. This lab was composed of three experiments. One involved the … Read more
Amounting to the largest biomass on the planet, bacteriophages are seen to have a huge potential in the biopharmaceutical landscape. With the rapid emergence of antibiotic resistance in bacterial pathogens, research interest in phage therapy has grown. Controlling the lytic action of phages will allow for the development of an inducible phage therapy and will … Read more
CHAPTER 1 INTRODUCTION 1.1 WHAT IS GENETIC ENGINEERING? Genetic engineering or genetic modification is the alteration or modification of an organism’s genome using modern DNA technology (Biotechnology). It usually involves the introduction of foreign DNA or synthetic genes into the organism; the new resulting organism is often referred to as transgenic and or genetically modified … Read more
1. Abstract Myofibrillar Myopathy (MFM) is a muscular disorder involving myofibrillar disarrangement commencing at the Z-discs. This condition displays great variety in clinical features and several genes have been found to be associated. Due to this genetic heterogeneity, MFM has been divided into subtypes based on the gene affected (MFM1-MFM8). Current diagnosis of MFM is … Read more
