Surface emissivity is a measure of inherent efficiency of land surface. It is applied to convert heat energy into radiant energy. In this study, an unmixing pixel based algorithm was proposed to compute pixel effective emissivity for Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data within Beijing, China. In this paper, vegetation, together with water and 3 kinds of ma...

This enzyme, called the photosynthetic water oxidation complex (WOC), liberates protons and electrons needed for energy production and reduction of NADP’ and quinones that are essential for plant growth. The 0, formed in Equation 1 is not essential for plant survival, but is essential for other organisms on Earth, since it is by far the major source of global OL production for the atmosphere. T...

Alkylphenols and their precursors, alkylphenol etoxylates, are a group of manmade chemicals used mainly as surfactants in domestic and industrial applications worldwide. It has been well established that they have endocrine disruption activity, hepatotoxic, genotoxic and other negative effects on animal and human health. In spite of the effort to reduce their use, they persist in the environmen...

this paper examines the relationship between domestic water sources, demand and associated problems in the context of a rapidly increasing household population in nassarawa eggon town, nasarawa state, nigeria. the data for this research were generated using a questionnaire survey of systematically selected households, and analysed using descriptive statistics in the form of frequencies and perc...

Pattern recognition uses measurements from an input domain, X, to predict their labels from an output domain, Y. Image analysis is one setting where one might want to infer whether a pixel patch contains an object that is “manmade” (such as a building) or “natural” (such as a tree). Suppose the label for a pixel patch is “manmade”; if the label for a nearby pixel patch is then more likely to be...

Abstract This paper documents the structure of flow and bed morphology a cutoff meander Danube River in relationship with GIS approach. The cutoffs effect produce changes repartition water sediment fluxes between natural channel manmade canal, direct implications on environmental evolution delta. Dranov de Jos (Lower ‒ LDM) belt seems to be one most affected by rectification works performed Sfâ...
