Background of study: Coronary artery disease is the single largest killer of both men and women worldwide. Coronary artery disease (ischemic heart disease) has been defined as “impairment of heart function due to inadequate blood flow to the heart compared to its needs, caused by obstructive changes in the coronary circulation to the heart. The risk factors that precipitate Coronary artery disease can be presented in two categories that is modifiable and non-modifiable risk factors. Modifiable risk factors is one over which individual may access control.

This study assessed the influence of gender in property access and control among the Kisii people of Kenya. The study was guided by two objectives; identify key properties in Kisii County and establish the relationship between access and control over property and gender. Properties identified were residential houses, land, cattle, poultry, goats, commercial plots, houses, sheep and motor vehicles. However, this study focused on houses, land and livestock. Findings revealed men had unlimited access to family properties while women had limited access.

Pseudomonas aeruginosa is intrinsically resistant to several antimicrobials and rapidly develop resistance to other drugs during treatment and make it difficult and ineffective. In this study Pseudomonas aeruginosa was isolated and clinically characterized from clinical samples and its antibiotic sensitivity pattern towards commonly prescribed Beta-lactum antibiotic disc.

The research study investigated the extent of awareness of safety rules and regulations in science laboratories in secondary schools in Ebonyi State. It investigated the extent science students in rural and urban secondary schools in Ebonyi State are aware of safety rules and regulations in science laboratories. The researchers used 45 secondary schools selected through stratified random sampling technique, SS3 classes selected using purposive sampling technique and 900 students selected through random sampling. The researchers adopted a descriptive survey design.

Soil salinity is a major limitation to plant in many areas of the world. Present study has explored the effect of salinity on Proline content, mineral composition and antioxidant enzyme of tomato. Tomato plants were exposed to 0, 60, 90,120,150 mM NaCl.The Proline accumulation was studied by reading the absorption of chromophore at 520nm using spectrophotometer. The content of proline increase in tomato as the level of NaCl increase. Using atomic absorption spectrophotometer ion uptake for Na+, K+, Ca+ and Mg2+ were determined.

Soil contains a number of microorganisms with nutritional diversity. These bacteria produce many extra cellular and intracellular enzymes which are used for various purposes. Some of these extracellular enzymes are important for agro based industries that in turn opens scope for searching cost effective and easy to operate screening of such important extracellular enzymes. Present paper describes a review on screening methods for extracellular enzymes. It includes screening for extracellular amylase, lipase and proteases.

Solid waste is a visible concern in any environment especially for a tourist destination like Zanzibar. Zanzibar as the most rapidly growing tourist destination cannot afford to allow unsightly piles of solid waste and wind-blown litter on its streets. This will endanger its natural beauty, environmental and aesthetic value. This study examines the attitude of households towards solid waste management services and practices that can serve as an index for solid waste control.

The constant transformation of space comes as a result of established socio-environmental, economic and cultural relations. In order to understand the relationships between the patterns and processes in the landscape, considering or not the hierarchical organization, the development of methods for the quantification of their structure has been used. This study focuses on analyzing temporal dynamics of landscape and land cover in Americana (SP Brazil in 1994, 2008 and 2016) aiming to diagnose the landscape urbanity through the application of The Urbanity Index (UI).

Metribuzin considered as pre and post emergent herbicide used to remove a wide range of grass weeds. We investigate the sub-chronic cytotoxic effect of metribuzin in male albino rats that intubated orally with 0,110,220, and 440 mg/kg for three months twice per week. We founded that metribuzin containing herbicide Sencor 70% caused decrease in weight gain ratio of albino rats that was proportional with increase in dose level.
