Yield variability of selected winter wheat cultivars under different sowing rate and selected application, was investigated during 2006-2008, in the Lower Silesia region (South-West Poland). Experiments with two varieties, two levels of sowing rate and seven herbicides, including untreated object were set up on the same field, using split-plot method. For evaluation of yield stability Kang'...

The MRI environment restricts the types of populations and tasks that can be studied by cognitive neuroscientists (e.g., young infants, face-to-face communication). FNIRS is a neuroimaging modality that records the same physiological signal as fMRI but without the constraints of MRI, and with better spatial localization than EEG. However, research in the fNIRS community largely lacks the analyt...

introduction: water is the main carrier of herbicides (hc) that its quality plays an important role in herbicide performance hard water has a high concentration of ca++ and mg++ and reviews have shown that calcium, manganese and zinc are the main factors reducing the effectiveness of weak acid herbicides. weak acid herbicides such as glyphosate, paraquat, clethodim and 2, 4 d are compounds that...

Recently the nonlocal coherent-potential approximation (NLCPA) has been introduced by Jarrell and Krishnamurthy for describing the electronic structure of substitutionally-disordered systems. The NLCPA provides systematic corrections to the widely used coherent-potential approximation (CPA) whilst preserving the full symmetry of the underlying lattice. Here an analytical and systematic numerica...

This work presents a method of screening of alkanophenoxy carboxylic (2,4-D, 2,4,5-T, MCPA, MCPP) and phenolic (dinoterb, dinoseb, pentachlorophenol) herbicides in water. The successive steps of the method, i.e. liquid-liquid extraction with ethyl acetate and methyl-tert-butyl ether and solid phase extraction using C18-modified silica gel and styrenedivinylbenzene copolymer-packed cartridges as...

We describe a Model RSM2 (A Reliable and Scalable Multicast Model). The approach we adopt uses Proactive-Routing, Minimum-Cost Path Algorithm, Combo-casting, Active Server Based Recovery, NACKBased acknowledgement, Buffer Management, Optimized Flooding Algorithm. The main characteristic of RSM2 model is, to provide complete multicasting, i.e. at the same time more than one node can act as sende...

. The drift of MCPA downwind of an aerial application was measured using short air sampling intervals in an attempt to estimate “real-time” concentrations. Prior drift studies examined deposition patterns or measured air concentrations downwind of pesticide applications using long sampling intervals (1 to 24 hours). This preliminary study was designed to determine: 1) the Eeasibility of “real-t...
