Different strategies of the application of nutrients are required to overcome the adverse effects of mustard (Brassica juncea L.) in response to NaCl stress. The objective of the present study was to determine if different added levels of nitrogen (N) in growth medium could alleviate the adverse effects of salt stress on photosynthetic capacity and accumulation of osmoprotectants and nutrients....

Problem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and 2010 to evaluate t...

A mixed bacterial culture consisted of Staphylococcus sp., Bacillus circulans-I and -II has been enriched from contaminated soil collected from the vicinity of an endosulfan processing industry. The degradation of endosulfan by mixed bacterial culture was studied in aerobic and facultative anaerobic conditions via batch experiments with an initial endosulfan concentration of 50mg/L. After 3 wee...

Background Al Rabta is a rural area in the North-West of Libya that represents an important focus of zoonotic cutaneous leishmaniasis. This study aimed to evaluate the effect of Ultra Low Volume (ULV) applications in controlling sand flies and its impact on leishmaniasis transmission in this area. Methods Two neighboring villages were selected: Al Rabta West (RW) as cypermethrin treated villa...

Abstract The presence of gravel in soils modifies the porosity, pore connectivity and size distribution soil matrix as well matrix-gravel interfaces. aim present study is to investigate effect relative volume samples with mass fractions 5,10, 20 wt% varying bulk densities (1.3, 1.45, 1.55, 1.60, 1.65 g cm –3 ) on (i) total field capacity, plant available water holding (ii) (iii) thermal capacit...

Sand Intermittent Filtration (SIF) is an established technology of wastewater treatment and in recent years it gains renewed interest due to its simplicity less energy requirement. The aim the present study was evaluate modified filter-bed Reactor using Sand-intermittent-filtration for removal physicochemical parameters viz dissolved oxygen (DO), biochemical demand (BOD), chemical (COD), total ...

Developing alternative high dielectric constant (k) materials for use as gate dielectrics is essential for continued advances in conventional inorganic CMOS and organic thin film transistors (OTFTs). Thicker films of high-k materials suppress tunneling leakage currents while providing effective capacitances comparable to those of thin films of lower-k materials. Self-assembled monolayers (SAMs)...

Clams, Donax variabilis, responded to sound stimuli presented to them in a laboratory aquarium by jumping out of the sand, lying on the sand for several seconds, and digging in again. On a beach, clams jump out of the sand and ride waves, migrating shoreward with the rising tide and seaward with the falling tide. Parallels between clam behavior on a beach and that elicited in the laboratory sug...
