To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2<...

ultrasound-assisted extraction was used to determine the optimum processing conditions and to achieve the maximum extraction yield and viscosity of the gum extracted from quince seed. using response surface methodology (rsm) to design the experiments and adopting the central composite rotatable design (ccrd), the effect of extraction temperature (25-55°c), time (3-10 minutes), and ph (6-8) were...

Researchers use a wide range of confidence scales when measuring the relationship between confidence and accuracy in reports from memory, with the highest number usually representing the greatest confidence (e.g., 4-point, 20-point, and 100-point scales). The assumption seems to be that the range of the scale has little bearing on the confidence-accuracy relationship. In two old/new recognition...

By evaluation of an extensive yield database a biomass yield model [bym] was developed. It is based on site specific yield functions and crop rotation algorithms. In combination with geodata it is possible to calculate regional biomass on the level of municipalities. The conversion to a GIS was performed in Visual Basic for Application (VBA). Exemplary winter rye production for bioethanol in th...

This paper presents a closed form yield model that takes into account constraints of an architecture. It applies to architectures that approximate global redundancy and for which the constraints translate into yield losses. The impact of the constraints on yield was evaluated by calculating the probability of observing non-tolerable defect patterns and by subtracting these probabilities from yi...
