mechanisms to enhance plant growth and development to improve plant stress tolerance and to prevent plants from soil-borne infections. These mechanisms include the production of ACC deaminase in the developing plant’s roots to lessen the level of ethylene (Dey et al. 2004), producing phytohormones (Mishra et al. 2010) and biological N2 fixation (Ardakani et al. 2010). The plants also exhibit antagonistic activity against phytopathogenic microorganisms by producing siderophores, chitinases,…

Lead concentrations can be measured in various body tissues or by measuring the biomarkers of the toxic effects of lead. The concentration of lead in the body has been measured in blood, bone, nails, hair, teeth, urine, faces and saliva for screening and diagnostic purposes. In all samples, specimen collection, storage and processing must be meticulously performed to avoid contamination of the samples with lead in the surrounding environment. Teeth, nail and bone reflect long term exposure to…

Abstract: Every year, more than 11 billion pounds of unused feathers result from the poultry industry worldwide, which in effect impose a difficult disposal process to the environment. Chicken feathers are an abundant, inconvenient and troublesome waste product from the poultry industry that can be utilised as a source of keratin. In addition to keratin, feathers contain other fatty and waxy substances. An original chicken feather contains many biological organisms…

INTRODUCTION The purpose of this experiment was to demonstrate the stereochemistry of the electrophilic addition using (E)-Stilbene, a trans-isomer of ethylene. Bromine was added and reacted with (E)-Stilbene to form an alkene. A product was made with both a meso-stilbene dibromide and a d/l-stilbene dibromide, which is trans-stilbene dibromide. DISCUSSION AND CONCLUSION For the reaction to form these two different compounds with the same starting reactants, the double bond of (E)-Stilbene…

World War 1 and Germany’s use of it within the last century. It’s less known for its chemotherapeutic side effects that could possibly extend many cancer patients’ lives. Effects on the human body Sulfur mustard is illustrated by the mixture of ethylene and sulfur dichloride which creates a reaction, the…

1.5 MUSEUMS AND PESTICIDE Museum collections are very susceptible to pest damage and pest control in museum environments is tricky. Damage can sometimes go unnoticed for years due to the gradual nature of the deterioration as well as the often-concealed storage of items. The damage caused can be irrevocable. However, sadly, so can the problems caused by the solution. Moreover, different government regulations have restricted the amount and the types of pesticides that institutions can actually…

In modern Western society, avoiding contact with the numerous pollutants and substances that can trigger an asthma attack is virtually impossible. In the home, the workplace, even in the air we breathe, we're surrounded by an endless list of potential asthma triggers. A vast range of stimuli can trigger asthma attacks. Chief culprits include dust mites, air conditioning (which cycles offending substances into the air we breathe) and something as simple as cat dander! Individual asthmatics,…
