A historical cohort study of the morbidity of CS2 and control workers was carried out in a viscose rayon factory and an adjacent cotton mill. A total of 725 male workers was employed at the two factories on I May 1966. All records of medical treatment received by these men from general practitioners, hospitals, and plant clinics for the period from I May 1966 to 31 December 1970 were obtained f...
A laboratory soil column experiment was first conducted to analyze water movement in latosol of sugarcane field under drip irrigation from single-point source at different emitter discharge rates. Next, a mathematical model of soil water movement under drip irrigation from single-point source was built using Hydrus-3D, which could accurately simulate the shape of the wetted soil volume and the ...
An irrigation runoff study on a residential lawn was conducted in California, northeast of Sacramento, during the summer and fall of 2008 to investigate the contribution of turf uses of pyrethroids to residues in Californian urban creek sediments. This study examined how over irrigation (i.e., irrigation that produces runoff) in the summer season may transport recently applied pyrethroids. The ...
In this study, the impact of some organic matters and a moisture super absorbent were investigated on available water and delay of permanent wilting point in a sample soil of Rasht landscape. In incubation stage, 12 Treatments including control (70% v/v soil with 30% of the composted manure) and various amounts of soil, municipal compost, composted manure, olives and rice wastes along with a su...
Supplementary irrigation is one of the most effective field management practices to improve water productivity and crop yield in rainfed conditions. Time of supplementary irrigation is another important parameter affecting the enhancement of yield. In order to study the effect of supplementary irrigation time as well as planting date, two factors, namely: 1) supplementary irrigation (No irrigat...
let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
Arsenic (As) is a well-known toxic metalloid found naturally and released by different industries, especially in developing countries. Purple nonsulfur bacteria (PNSB) are known for wastewater treatment and plant growth promoting abilities. As-resistant PNSB were isolated from a fish pond. Based on As-resistance and plant growth promoting attributes, 2 isolates CS2 and SS5 were selected and ide...
[1] An extensive set of carbonyl sulfide (OCS) and carbon disulfide (CS2) observations were made as part of the NASA Transport and Chemical Evolution over the Pacific (TRACE-P) project, which took place in the early spring 2001. TRACE-P sampling focused on the western Pacific region but in total included the geographic region 110 E to 290 E longitude, 5 N to 50 N latitude, and 0–12 km altitude....
introduction in agricultural ecosystems, organic fertilizers play an important role in producing sustainable agricultural production. considering this sajjadi nik et al (2011) reported that with increasing of vermicompost inoculation with nitroxin biofertilizer, capsule number per sesame plant increased, so that the most of capsule number per plant (124.7) was observed in 10 t/h vermicompost wi...
