Morphological ampelography characteristics, technological, phenolic and tannic maturities were studied over four seasons (from 2009 to 2012) of Ahmeur Bouamer autochtonous Algerian variety. During the harvests, Bouamer's cluster has showed a high quality morphological parameters (weight, size, number seeds/ berries per cluster).The weight was proportional size which moderately compact, thus avo...

The design of a windmill rotor is critical for harnessing wind energy. In this work, study conducted to optimize the and performance blade that suitable low conditions. windmills’ blades are aerodynamically designed based on SG6043 airfoil speed data at local selected sites. aerodynamic profile can provide maximum power coefficient, which relation between real available energy given reference a...

in line with the unprecedented development of public sector in the 20th century, many economists have studied the efficiency of the public sector in economic growth and development. evidently, one of the important aspects of these studies is to determine the optimum size of government whose theoretical principles and approaches as well as practical methods have been argued about in public secto...

the optimum road spacing has been studied by many researches. it is an important step of forest road network planning. the goals of this study are determining the optimum road spacing in kheiroudkenar forest of nowshahr in northern iran and study of effect of kind of skidder on skidding cost and road spacing. continues time study method was used to determine the production rate of taf and timbe...

the conditions for the refinement of clarified sugarcane juice, including temperature (50o, 60o and 70oc) and pressure (0, 0.5, 1 and 1.5 bars) by micro-filtration membrane technology were investigated. the raw sugarcane juice was initially pre-filtrated with lime and then the juice obtained (clarified juice) processed using a ceramic micro-filter mem-brane (0.2 micrometer). the characteristics...

the performance of a γ-al 2 o 3 /n-decane nanofluid shell-and-tube heat exchanger in a biomass heating plant is analyzed to specify the optimum condition based on the maximum heat transfer rate and performance index for wide range of nanoparticle volume fraction (0–7%). compared with pure          n-decane, the obtained results in this research show that by using γ-al 2 o 3 /n-decane nanofluid ...

in quality control charts, the problem of determining the optimum process mean arises when the deviation of a quality characteristic in one direction is more harmful than in the opposite direction. the failure mode in these two directions is usually different. a great majority of researches in this area have considered asymmet-ric cost function for processes with single quality characteristics....

information on the productivity, costs and applications of the logging system is a key component in the evaluation of management plans for the rehabilitation and utilization of caspian forests. skidding and road construction costs are expensive forest operations. determining the optimum forest road network density is one of the most important factors in sustainable forest management. logging me...

Porosity, and in particular pore size is one of the most important considerations development porous carbons for CO 2 capture. Current methods determining optimum size...
