abstract plant roots absorb water and minerals from soil solution. plant production is a function of root distribution and its activity in soil. by increasing root density in soil unit volume, roots absorb more water and minerals. this implies that knowledge of root development is an important factor for crop production. to determine the most suitable amount of water for the maximum development...

Predicting potable water quality is more effective for management and pollution prevention. Polluted causes serious waterborne illnesses poses a threat to human health. the of drinkable may reduce incidence water-related diseases. The latest machine learning approach has shown promising predictive accuracy quality. This research uses five different algorithms determine drinking First, data gath...

Chunnakam and Vadamaradchi are two major aquifer systems in Jaffna Peninsula, Sri Lanka. This study was performed to compare water quality in the domestic wells in these aquifers and to assess the efficacy of household water treatments for treating contaminated water. Replicate well water samples were collected from each aquifer and pH, dissolved oxygen (DO), conductivity, total dissolved solid...

An antibody-functionalized gold nanorod array enables the realization of a reusable early-warning system for detecting harmful pathogens dispersed in drinkable water.

The rational design of a mercury(II) ligand consisting in a 1-(4'-oxyphenyl)-4(1'-pyrenyl)-2,3-diaza-1,3-butadiene receptor unit, optimizes the sensitivity and reliability of a SPR sensor by the formation of a well packed SAM over the gold surface. SPR analysis allows detecting mercury(II) concentrations in aqueous systems in the picomolar range, meliorating on three orders of magnitude the EU ...

Sanitation improvement is crucial in saving lives that are lost due to water contamination. Progress towards achieving full sanitation coverage is still slow in low-income informal settlements in most developing countries. Furthermore, resources are being wasted on installing facilities that are later misused or never used because they do not meet the local demand. Understanding demand for impr...

The drinkable yogurt marketplace is a competitive and growing category in the dairy industry. Understanding sensory differences is critical for understanding the product, and ultimately, consumer preference. The objective of this study was to identify and define the sensory characteristics of commercial drinkable yogurts and link these specific sensory attributes to consumer preferences among C...

an indirect tarns-log production function was employed to estimate the demand functions for such inputs as: fertilizer, seed, pesticide, water recourse and machinery as subject to budget constraint and while using data related to cotton producers in the three provinces of north khorasan, khorasane razavi, and south khorasan in 2007-8. lagrange coefficients with relation to cotton producers in t...
