BACKGROUND The use of gold nanoparticles (Au-NP) based medical applications is rising due to their unique physical and chemical properties. Diagnostic devices based on Au-NP are already available in the market or are in clinical trials and Au-NP based therapeutics and theranostics (combined diagnostic and treatment modality) are in the research and development phase. Currently, no information o...

7 Soil structure is often said to be the key to soil productivity since a fertile soil, with desirable 8 soil structure and adequate moisture supply, constitutes a productive soil. Soil structure 9 influences soil water movement and retention, erosion, crusting, nutrient recycling, root 10 penetration and crop yield. The objective of this work is to study, humic acid (HA) 11 application on some...

We investigated the prevalence and diversity of Escherichia coli strains isolated from surface waters from multiple watersheds within the South Nation River basin in eastern Ontario, Canada. The basin is composed of mixed but primarily agricultural land uses. From March 2004 to November 2007, a total of 2,004 surface water samples were collected from 24 sampling sites. E. coli densities ranged ...

soilless media have different physical properties. change in air space of mix substrate can cause change in fertigation management and plant growth and yield. physical properties (water holding capacity, effective air-filled pore space, effective pore space) of 50 mixed substrates were measured to evaluate the effect of air-filled pore space on growth of tomato transplant and it's water us...

triticale (x triticosecale wittmack) is a hybrid seed plant result from wheat and secale. this seed has high amylolitic and protelytic activities, introducing it as adjuncts in mashing process. in this study, influence of malting process on physico-chemical properties variety of barley (namely sahra) and triticale and malt quality of them were investigate. malt of barley was selected as referen...
