To what extent can humans change to contribute and preserve the environment? Pollution, landfill, chemical waste, climate change, and natural disasters are only a few examples of the consequences we have created due to our linear economical model not being compatible with the environmental cyclical cycle. So what are the problems and how are we contributing to them in the first place? What might be some of the things we can do in order to better our situation? Lastly, if the environmental…

1.5. Enzyme-Polysaccharide Interactions Proteins and enzymes have become an integral part of many industrial processes as well as being applied both in cosmetics and in therapeutics. Due to advances in biotechnology and genetic engineering, mass production of protein and enzymes has become feasible. Use of enzymes is environmentally friendly as they catalyse reactions under mild conditions against polluting inorganic catalysts which works in the extremes of pH and temperature. However, this can…

Over the course of years Forensic Anthropology and Biology has coincided with the criminal court system, and has had the ability to help face dangerous individuals with justice and to find these individuals guilty. Forensic Biology is defined as the application of science where the process of identifying badly decomposed, skeletal, or that of unidentified human remains is done. Forensic Anthropology is defined as the application of science that involves the physical anthropology to the criminal…

E-number food additives, their chemistry and role in food Since the dawn of time, humans had using several simpler and yet natural food preservation techniques such as preserving meat using salt, or immersing onions and cucumber in a jar of vinegar to keep the food fresh and last longer. The method of preserving food had been evolved over a significant period of time. (Heldman, 2003) Food additives are either a natural or synthetic substances which was added intentionally to food to improve the…

This chapter discusses about the health hazard and hygiene in the workplace. Hazards can be found in every workplace. Hazard is generally anything that makes you in a dangerous situation. Health hazard is means that the hazard brings negative effect and harm to the health which is may cause measurable changes in the body. There are many hazard in the workplaces have the potential to harm workers short-term and long-term health result in diseases, disorders and injuries (Alison et. al., 2008).…

The world of forensic science is full of ever developing technology. Analyzing forensic evidence involves using fingerprints, hair samples, blood, footprints, bite marks, and other sources of material to help identify someone. Every small piece of evidence found at a crime scene can be crucial — leaving the slightest trace of saliva or skin cells can be what convicts a person. Few people know the importance of forensic science more than Steven Avery. In Making A Murderer, the ten part…

Aromatic plants bear essential oils which are fragrant and so are named ‘Aromatic’. These plants retain their fragrant components in specialised cells and tissues of organs even after drying. Oil may be present in external glands as epidermal cells or their modification such as ‘Secretory Hair’ or may be present internally throughout the plant forming Schizogenous formation which on dissolution of surrounding cells forms Schizolysogenous gland which further grow into long canals. Secretion such…

1. Introduction Alpacas are a member of the camelid family from South America, where they live in the semi-arid areas of the high-altitude plateau. They are famous for their soft fleece, which is known for its good strength and a range of natural coat colors from solid white to black. Not only does the coat color of the alpaca have important economic value, alpaca is also a perfect animal model in which to study the mechanisms controlling mammalian coat color genes. Mammalian coat colors are…

Resistance and Contemporariness in Kaine Agary’s Yellow Yellow Introduction African literature has come of age through several sections, from the scripts of prehistoric Egypt through the oral form of transmission, which celebrated human and supernatural achievement rendered in songs by court bards, griots, troubadours, public dances, and masks.
