DOI: https://doi.org/10.30564/jasr.v4i2.3229

Abstract


In the present review article human diseases caused by various groups of pathogens have been explained with its etiology, epidemiology and treatment. In addition, effect of climatic changes on parasites and pathogens has been demarcated with rising incidences of diseases. In response to environmental changes, mainly external and internal microenvironment of body and drug regimens taken by patients; virus is regularly changing its form and new mutant variants are coming out. These are circulating in many Indian states and cross border countries and causing high infectivity and mortality in human patients. These variants with new mutations are challenging existing drugs and other prophylactic measures and massively disrupting functions of a tissue, organ, or entire organism. Diseases caused by viruses are showing new trends in virulence, with high infectivity, morbidity and mortality. Due to climatic effect and drug resistance and new mutations in pathogens disease burden has been exacerbated enormously at global level. In all cases of helminthes, protozoan’s, fungi, bacteria, virus pathogens and parasites available drug structure seem to be failed or their usefulness has been much reduced due to evolution of new mutant variants with multiple drug resistance. There are serious failures at the level of operation, management and control of disease. The utmost failure is due to lack of appropriate vaccine, drug regimens, clinical care and awareness among people. These are major reasons that is why diseases become uncontrolled and unmanageable.

Impact of Polymer Coating on the Flexural Strength and Deflection Characteristics of Fiber-Reinforced Concrete Beams

Impact of Polymer Coating on the Flexural Strength and Deflection Characteristics of Fiber-Reinforced Concrete Beams DOI:  https://doi.org/10.30564/jbms.v4i2.5304 Abstract Liquid polymers (LP) have become an important structural material used in the construction industry in the last decade. This paper investigates the viability of using commercially available LPs as a coating material to improve the flexural strength of fiber-modified concrete beams. The scope included preparing rectangular prism concrete beams with a concrete mixture including fly ash and fiber and coating them with four different liquid polymers at a uniform thickness following the curing process while one set of samples was maintained under the same conditions as a control group without coating. In addition, cylindrical samples were prepared to determine the compressive strength of the concrete mixture. Following the curing process in an unconfined open-air laboratory environment for another 28 days, concrete sample

Achieving Sustainable Use and Management of Water Resources for Irrigation in Nigeria DOI:  https://doi.org/10.30564/jees.v2i2.2505 Abstract Water resource is available in Nigeria to meet water demand for domestic, agricultural and industrial use. If well enhanced and protected from various source of pollution. However, less information is available on suitability of water resources for irrigation use in Nigeria. This article reviews literature of the past with regards to influence of geogenic and anthropogenic activities on water resource for irrigation purpose in Nigeria and also to explain the current state of suitability of water resource for irrigation studies in Nigeria and gaps in studies. It also summarizes future ways on water resource management and preventive measure for water resource pollution for irrigation use. Related articles were downloaded from Google scholar in water-related issues. This paper tends to review previous article on water resource in Nigeria, and its su

Soil Bunds Effect on Soil Properties under Different Topographies of the Southwest Ethiopia

Soil Bunds Effect on Soil Properties under Different Topographies of the Southwest Ethiopia Abstract Soil erosion is a major environmental problem affecting development endeavor. Physical soil and water conservation (SWC) measures such as soil bunds are implemented to mitigate soil erosion. However, information on the effects of soil bunds on soil fertility is limited. This study was aimed to evaluate soil quality in fields with soil bunds and with no soil bunds in steep, middle and lower sloping cultivated lands as well as spatial variation of soil properties in between bunds in southwest Ethiopia. About 7-15 years old bunds and nearby cultivated fields lacking bunds were assessed. From 0 cm-20 cm soil depth, a 36 soil samples were collected. Soil texture, soil organic carbon (SOC), total nitrogen (N tot ) and exchangeable potassium (K exch ) were analyzed. Soil bunds showed significantly ( p <0.0.5) greater clay but less sand than adjacent no-bund fields. In steep, middle, and low
