glutamate as one of the most important neurotransmitter in the brain has a significant role in control of foodintake. this study examined the central effect of chicago sky blue 6b (csb6 ) as glutamate vesicular uptake inhibitor, on food and water intake in broilers. after icv injection of csb6 cumulative food and water intake were measured in 15,30,60,120 and 180 minutes. csb6 increased food in...

to design the equipment and facilities for preservation, storage and processing of pomegranate, it is necessary to know the specific heat and thermal conductivity of the fruit components. the specific heat of exocarp, mesocarp and of seeds of pomegranate were assessed at three moisture content levels (30, 50 and 76% for seed and mesocarp; 15, 35 and 52% for exocarp) and at four temperature leve...

gypsum found in the soil beneath the foundation of structures, specially hydraulic structures, can cause serious damage to them. the mechanical behavior of gypsiferous soils has not so far been investigated in detail except for the works of petrukhin (1993). here, it has been tried to investigate the mechanical behavior and the effect of soil being leached on settlement and strength of these ki...

abstract statistical methods are one of the useful tools for climatic elements and their behaviors analysis, as well as, modeling and predicting them subtly. in this paper the behavior of time series of annual temperature of zanjan during 1956-2005 have been studied. so, based on autocorrelation, correlation coefficient, and spearman and mann - kendall ways, the data trend was determined. the a...

the purpose of this study was to examine the effectiveness of nanosilver colloid as a new antimicrobial agent against erwinia in tissue culture of sugar beet for the recovery of the contaminated doubled haploid plantlets. the nanosilver colloidal solution of 4000 ppm was diluted in different concentrations (0, 50, 75, 100 and 125 ppm) and was added to the solid ms medium. in a factorial experim...

introduction todays, the application of new methods for monitoring and online management of agricultural farms is necessary to increase quality and quantity of agricultural products. remote sensing is one of the technologies that can be used to monitor agricultural farms and natural resources. this technology is capable of detection and prediction of farm changes by application of satellite and...

urmia lake is the largest lake in the country which during recent years faces a dramatic reduction in the water level. many reasons such as climate change, continuous droughts, development of cultivation and land use changes as well as construction of dams were mentioned, but the provided reasons have less been well documented by scientific evidences. this study is an attempt to investigate the...

the present study carried out an in vitro experiment on effects of salinity and temperature on acartia tonsa life cycle from caspian sea. during the experiment, temperature and salinity ranged 25, 27, 29 ± 1 °c and 12‰ and 17‰, respectively within a period of 60 days. spawning rate was measured using mesh size of 100 µ planktonic net from surface to 10 m depth. early results show that nauplii a...

background and objectives: over the last decade, climate change has been one of the most challenging issues in the scientific papers. studying the impacts of climate change on crop productivity at regional scale will depend on the right estimate of future climate. this estimation is being implemented by climate models and most of them by general circulation models (gcms). this study aims at pre...

in this study, precipitated calcium carbonate (pcc) was modified using cationic starch, and its effect on optical and physical properties of paper was examined in comparison with unmodified filler afterwards. to determine the filler retention in paper, both modified and unmodified fillers were added to pulp suspensions by 20, 30, and 40 percentages. for comparing the utilization effect of modif...
