Microbial transformation has proven to be an important resource in the production of various chemicals used in the pharmaceutical and agrochemical industries.1 Microorganisms, such as fungi have been widely used in biotransformation experimentsto yield bioactive metabolites. Many of these reactions are difficult to achieve by chemical synthetic protocols. As a result, fungi have played an integral role in the development of green chemistry and by extension the pharmaceutical industry.

Introduction

Background

Fish is an essential and traditional element in the diet of most Caribbean people. However it also contains methylmercury which can have severe effects on fetal neurodevelopment. The objective of this study was to assess the fish intake of a selected group of pregnant women from Jamaica and Trinidad & Tobago and evaluate prenatal mercury exposure, using the placenta as a biomarker.

Method

Introduction

Minerals and Radioactive nuclides exist naturally in the environment and some are created by human activities. They are then absorbed by food where they can affect human health. Therefore it is essential to determine the concentration of radioactive elements and minerals in the food. The purpose of this study wasto measure radionuclides and mineral contents that are present in popular Jamaican foods.

Methods

Traditionally, educational systems worldwide have focused mainly on the use of chalkboards and whiteboards. However, in recent years, they have been replaced by the smart board.

There has been an increase in the amount of information needed to communicate new concepts, and the methods used to teach this information need to be more interactive in order to suit the learning styles of young and technologically savvy students, as well as to maintain their interest in the classroom.

With the increasing development of infrastructure and information and communication technologies (ICTs), there is an increased dependency on wireless technologies in a variety of user environments. The users of wireless networks are always concerned about the performance of such networks, which is dependent on both the network design as well as environmental conditions.

Geographic isolation coupled with human selection of Cannabis sativa has given rise to the subspecies Cannabis sativa subspecies sativa and Cannabis sativa subspecies Indica. Modern day plant breeders have crosspollinated the two subspecies sativa and indica that are known as Cannabis hybrids. The therapeutic and medical value of these subspecies are distinct in their applications for the medical cannabis user.

In power grids, electricity is transmitted from power plants to substations, residential, and commercial facilities over power lines, which mainly run above ground. The electrical current that passes through power lines induces magnetic fields, which can then induce currents in nearby conductors. As the human body is a conductor of electricity, induced currents can excite human tissues. This may result in increased temperature, cancers, childhood leukemia, and nervous system disturbances, especially with prolonged exposure.

The Discovery Bay Special Fishery Conservation Area (Figure 1) is demonstrating anincrease in the abundance of fishes. Its environs however,remain smothered by macroalgae which are presumed to be due to eutrophication and relatively low herbivory rates. Both shoreline sources and up-wellings bring pollutants into the Bay.

Abstract:

Glasses in the range 50Bi2O3-30B2O3-(20-x)BaO-xRedmud, x = 0.1 to 0.5 wt.%, were synthesized and characterized for use as low melting point radiation shield glass solder using a combination of spectroscopic, thermal analysis and MCNP(X) simulation. The MCNP(X) simulation was used to determine the Gamma-ray half value layer (HVL) for several photon energies.
