INTRODUCTION Any food product, either vegetable or animal origin, has a definite shelf life. If the recommended temperature and humidity conditions for its storage are not maintained, food spoils at a very fast ratequickly as bacteria and other parasites from the environment take over. Therefore, the food should be eaten as fresh as possible. It is, however, difficult in the contemporary modern world as the population centers are furtherar away from where the food actually grows or comes fromgrown. Consequently, food preservation and processing has become a big industry where innovative and latestmodern technologies are used to minimize the threats of ...

Introduction

The human reproductive system can be affected by pathogens like any other organs. An example of a bacterium is Neiserria Gonorrhoeae, which causes gonorrhea in both males and females. The disease can be treated through normal antibiotics. This presentation will highlight the human reproductive system of both sexes; how gonorrhea is caused, diagnosed, and treated; and the short and long term effects of the disease.

Usually, a full-term incubation period lasts from 37 to 42 weeks, and the last few weeks of it are critically important, as baby's fundamental organs are developing, and the weight is increasing. A premature birth is the one happened before 37 week of the incubation period. Normally, late preterm babies look completely developed, yet regardless they have more serious dangers of wellbeing issues than children conceived full term. Preterm babies are usually born with complicated conditions. Some of the problems can be solved directly during the delivery; other can make an impact on whole future life. During childbirth, ...

1. Introduction Smallpox is a viral disease that causes pus-filled boils on the dermis. It looks similar to chickenpox, but has certain characteristic differences. Unlike chickenpox, smallpox is lethal in 30% of the cases and leaves the victim with disfiguring scars and/or blindness. Smallpox has now been eradicated through aggressive vaccination. The last case was reported in Somalia in the late 1970’s. After 2 years of worldwide surveillance, the World Health Organization (WHO) confirmed that the disease had been eradicated. 2.

Dissolved Oxygen

INTRODUCTION Dissolved oxygen is a useful parameter used to determine the level of effluent in waste water treatment. Living organisms in water bodies require oxygen to break down organic matter. These organisms consume the dissolved oxygen in water and give out carbon dioxide. Oxygen does not readily dissolve in water and gets depleted quickly by increased micro-organism activity. To maintain optimal oxygen levels in a water body, the oxygen replenishing rate from the air should be equal to dissolved oxygen use by micro-organism in the water. A curve drawn to represent dissolved oxygen levels down a stream from a point of effluent ...

Using “Deshelled” Chicken Eggs

Introduction Osmosis can be defined as the diffusion of water from an area where the concentration of water molecules is high, through a semi-permeable membrane to an area where the concentration of water molecules is low (1). Alternatively, osmosis can be thought of as a process by which water leaves an area of low solute concentration to an area of high solute concentration, in an effort to create an equilibrium. In a living cell, water molecules can move through the cell membrane, which is semi-permeable. In certain situations, solutions which are higher in solute concentration than a living cell will cause the ...

Introduction

Osmosis refers to the net water movement across a membrane, which is selectively permeable and the movement is driven by a difference in the concentration of the solutes on the opposite sides of the membrane. A selectively permeable membrane allows water to pass through without allowing ions or solute molecules to pass through. Other small molecules that are not charged are also allowed to pass through the membrane. Diffusion, on the other hand, refers to the movement of molecules in a random motion as a result of the kinetic energy and causes the molecules to have a net movement from areas where the particles ...

Abstract

IFITM3, a protein induced by interferon, restricts reovirus infection in host cells and inhibits the viral replication. It affects the proper penetration of the virus by altering the dynamics of the viral uncoating in the endosomes. This study is the first in characterizing the anti-viral activity of IFITM3 on non enveloped viruses that depend on endosome for cellular entry. Following contagion with a virus, the body triggers the release of a class of cytokines, interferons that are involved in first line of defense against infection. Type I interferons are specifically induced in the cells following insult with both DNA and RNA ...

Abstract

Tuberculosis, better known as TB, is an infectious disease that affects the global community. Its incidence rate has been significant in the New Zealand region where the disease is considered to be pandemic and has accrued a significant burden on the healthcare system for its demands on timely diagnosis and treatment. Although a decline of its incidence in New Zealand was noted, such decline halted sometime in the 1980’s and the rate of incidence becomes consistent thereafter and it remains to be an apparent health problem in the region which is highly associated with migration issues and other factors that ...

Introduction

Food items are always prone to spoilage which in most of the cases is precipitated by an increase in bad microbes that cause the food to change its property and thus food becomes unsafe for eating. The main purpose of inspection of food is to trace the presence of bad microbes that are available in most of the food products but below certain level they are harmless. Microbes are nothing but cells which are so microscopic that it is not possible to detect them when they are in very small numbers. In order to detect the presence of harmful ...
