finger vein is one of the most fitting biometric for identifying individuals. in this paper a new method for finger vein recognition is proposed. first the veins are extracted from finger vein images by using entropy based thresholding. in finger vein images the veins are appeared as dark lines. the method extracts veins as well, but the images are noisy, that means in addition to the veins the...

in order to evaluate efficiency of nitrogen fertilizers consumption in a sugar beet monogerm hybrid variety of zarghan, a field experiment was conducted in a loamy soil during 2007 in the research farm of sugar beet seed institute located in karaj. five levels of nitrogen fertilizers including 0 (check), 120, 160, 200 and 240 kg/ha of net nitrogen from urea fertilizer (46 percent of pure nitrog...

objective(s): up to now, many researches have been performed to improve the antitumoral effect of melanoma differentiation-associated gene-7 (mda-7) protein. the purpose of our research was to construct 3 expression vectors producing mda-7 in fusion with rgd (arginine-glycine-aspartic acid) peptide and evaluate their expression.     materials and methods: mda-7 gene with two different rgd seque...

theaim of the current study was to assess effects of different levels of origanum vulgare (0, 250, 500, 750 and 1000 mg/l) on kinetics of gas production, some ruminal digestion and fermentation parameters, methane production and also to determine its potential in controlling rumen acidosis using in vitro method in four separate phases. in the first phase, the asymptote of gas production (a) and...

introduction   capability evaluation can be considered as a basic strategy for land use becausethe development synchronous with the naturecan be achieved by using identifying and assessing of the ecological characteristics of the area. agricultural land suitability classification based on indigenous knowledge is vital to land-use planning (ecological capacity evaluation). execution of developme...

background and aim: nesfatin-1 is a newly discovered anti-appetite protein which is expressed in adipose tissue and appears in plasma. it has a significant role in energy homeostasis and metabolism. the aim of this study was to assess the effects of an 8-week endurance and resistance training on the plasma level of nesfatin-1, cardiorespiratory endurance, and body composition of overweight and ...

the effect of concentration and time of supplementary nitrogen fertilizer spray application on grain yield and nitrogen use efficiency in rapeseed (hyola401) as a second crop in paddy fields were evaluated in a field experiment conducted in randomized complete block design with 3 replications at rice research institute of iran (rasht) in 2008. in this experiment two factors, concentration of so...

in order to increase the productivity of human interleukin-2 (il-2) as a model protein in the recombinant e.colibl21 (de3), the effect of magnesium acetate and manganese acetate was studied based on full factorial design experiments magnesium acetate and manganese acetate and their interaction exhibited an increasing effect on il-2 expression level upto 25.24%, 16.80% and 23.30%, respectively, ...
