QUALITY ASSURANCE AND QUALITY CONTROL FOR WATER AND FOOD ANALYSIS

Great attention has been paid to food and water quality for centuries. The requirements have been changed according to the development of human knowledge in the field of nutrition, chemistry, microbiology, and analysis. It is necessary first to point out that the term food and water quality is a complex one that includes many indicators. For food and water to be classified as good, it has to fulfill the requirements, especially from the nutritional, sensory, hygienic-toxicological, and techn...

PRODUCTION OF INSECTICIDAL COMPOUNDS USING BACTERIA AND FUNGI

Pest and diseases have a serious effect on food production. Global crop yields are reduced by 20 to 40% annually due to impact of pests and diseases.Indiscriminate use of insecticides to combat insect challenges, have increased the selection pressure leading to resistance in insects. In such a situation, alternate options of insect control are advocated. The use of microbial insecticidal compounds offer adequate levels of insect control and pose fewer hazards.Microbial insecticidal compou...

A SEMINAR PRESENTATION ON PHYSICAL AND PHYSICO-CHEMICAL PROCESSES

Abstract Physical Separation process refers to all the mineral separation techniques that are based on exploiting the differences in specific physical properties of the mineral such as specific gravity, magnetic properties, thermal and electrical conductivity. Physical separation techniques are usually preferred for economic reasons. Physical separation techniques include; •Gravity separation process •Classifiers •Magnetic separation process •Electrical separation process •Separati...

MACHINE LEARNING IN INTERNET OF THINGs

IoT have the potential to revolutionize the way we view and sense the physical world in the area of Health, Governance, Buildings (Smart Building and Smart Houses), Security, exploration of the universe, etc. But this revolution can only be effective with Machine Learning in the core of analyzing IoT “Big Data”. After all, “of what use then is harvesting huge amount of data across the globe if we cannot analyze them to make predictive decisions for a future that is uncertain and dynamic...

Effect of Hibiscus sabdariffa Calyces Extract on Estrogen and Progesteron Level of Pregnant Albino Rats.

Abstract  This study investigated the effects of Hibiscus sabdariffa on the reproductive hormone of wistar rats.  Twenty eight wistar rats weighing between 160 – 200kg were used.  They were divided randomly into four groups (A – D) with seven animals in each of the groups.  Group A served as the control for group B and received 2ml of distilled water while group B orally received 2ml Hibiscus sabdariffa extract for 21 days, pregnancy was induced previously in these groups.  In the sa...

THE IMPACT OF THE ENVIRONMENT IN THE DISTRIBUTION OF PARASITIC INFECTIONS

A human or animal with an infection has another organism inside them which gets its sustenance (nourishment) from that person, it colonizes that person and reproduces inside them. The human with that organism (germ) inside is called the host, while the germ or pathogen is referred to as a parasitic organism. Another name for an organism that causes infection is an infectious agent. It is only an infection if the colonization harms the host i.e parasitic relationship. It feeds and multiply ...

BIODIVERSITY CONSERVATION AND ECOSYSTEM SERVICES FOR NATIONAL DEVELOPMENT

ABSTRACT  The most amazing feature of Earth is the existence of life, and the most extraordinary feature of life is its diversity. Human beings can coexist only with the abundance of and diversity of nature. It is widely acknowledged that biodiversity underpins ecosystem functioning and that the provisioning of ecosystem services is essential for human well-being. The relationship between biodiversity and ecosystem services is not straightforward, whether more biodiversity would imply more ...

Heterocyclics Compound Effects in Crude Oil

PREFACE Crude oil is a naturally occurring brown to black flammable liquid which is composed of hydrocarbon compounds, non hydrocarbon compounds, organometallic compounds. Various types of non hydrocarbon compounds present in crude oil are organic sulfur, nitrogen and oxygen compound. Traces of this compound causes problem to catalytic refining process in the refining industry. Hydro treatment process is used to eliminate the problems caused by this compound TABLE OF CONTENT  Abstract  CHAP...

GENETICS OF EPILEPSY

Genetics is a huge and growing area across human biology, medicine and science, providing information about basic processes from birth to death, from development to degeneration, and in even revealing enough about disease biology to lead to new therapies or better use of existing treatments because gene activity underlines all biological process (Sisodiya, 1881; Vadlamudi et al., 2014).  Epilepsy is defined as one unprovoked (or reflex) seizure and a probability of further seizures similar t...

GRAVITY METHOD IN GEOPHYSICAL PROSPECTING

Lateral density changes in the subsurface cause a change in the force of gravity at the surface. The intensity of the force of gravity due to a buried mass difference (concentration or void) is superimposed on the larger force of gravity due to the total mass of the earth. Thus, two components of gravity forces are measured at the Earth's surface: first, a general and relatively uniform component due to the total earth, and second, a component of much smaller size that varies due to lateral d...

Agrobacterium Tumefaciens as a Tool for Transformation.

Plant transformation mediated by Agrobacterium tumefaciens, a soil plant pathogenic bacterium, has become the most used method for the introduction of foreign genes into plant cells and the subsequent regeneration of transgenic plants. This review focuses on the host recognition and the process of gene transfer from Agrobacterium tumefaciens to plant cells which implies several essential steps.

WIRELESS ELECTRICITY

ABSTRACT Electric energy needs to be transported to the distribution lines through cords. One of the major issue in power transmission is the losses occurs during transmission and distribution process of electrical power due to the energy dissipation in the conductor and equipment used for transmission. As the demand increase day by day, the power generation and power loss are also increased. In addition, the cost of making electricity is harmful to the environment. Reducing transmission lo...
