Correlation between Enhanced Vegetation Indices and Rainfall Patterns of Kurnool District, Andhra Pradesh
Abstract: Vegetation indices enhance vegetation spectral signatures by combining bands of red (630–700 nm) and near-infrared wavelengths (700–1100 nm). This can be best suited to study vital activity of vegetation on land surface. Kurnool district is chosen to assess the capability of continuous spatial and temporal coverage; MODIS-derived enhanced vegetation indices (EVI) data were utilized to monitor the vegetation seasonal dynamics and their relationship with precipitation. Statistical analysis of mandal-wise mean …

Potentiality of Bacteriocins as the Attachment Inhibitors of HIV-1 gp120
Abstract: It is postulated that some bacteriocin derivatives are consummate candidates to inhibit the binding of HIV gp120 to CD4 T-cell. From the discovery of bacteriocin compounds in 1925 and forth, nearly 300 bacteriocins have been identified. Of various bacteriocins, there are some which have been used successfully for inhibiting both animal and human pathogens. Unfortunately, no large extent research has been found in the development of various bacteriocins as HIV …

Servo and Regulatory Response of Non-linear Spherical Tank System
Abstract: The highly nonlinear spherical tank system is employed in many process industries for huge storage. The nonlinearity is due to the cross-sectional area of the tank with respect to its height. Thus, the level control of the spherical tank system is a challenging task. The diverse controller methods are existing for level control, in which 95% of controllers employed are Proportional, Integral, and Derivative (PID) controllers. In this paper, to …

Anthropocentric Epistemology: Implications for the Search for a Viable Environmental Ethic
Abstract: This study is on the anthropocentric epistemology and implications for the search for a viable environmental ethic, identifies man’s relationship with the environment as a product of man’s epistemic base. Anthropocentric epistemology is anchored exclusively on the supremacy and objectification of the human perspective beyond and above all others. This model of epistemology ties everything to the whims of man and explains reality as such. Present environmental consciousness and preservation …
