green tea extract has plenty of antioxidant. due to the toxicity of synthetic antioxidants, it is necessary that these antioxidants in products such as donuts be replaced with natural antioxidants. the purpose of this research is to reduce the usage of synthetic antioxidants as it is possible. so the extract was extracted and it was used as a natural antioxidant in the dough of donuts. due to t...

the present study was designed to evaluate the drought tolerance of new sugar beet monogerm hybrids using polyethylene glycol 6000, under in vitro condition. the experiment was carried out as a factorial experiment based on completely randomized design with four replications in sugar beet seed institute, karaj in 2013. 23 new sugar beet monogerm hybrids with two tolerant and normal controls wer...

music consumption is a new topic in the academic literature, but the consumption of music itself has been part of human culture for centuries and all human more or less listen to it in order to fill their leisure time. marketers always find it challenging to identify the best way for selling music which at the same time can be accepted by different consumers, too. so, we tried to investigate th...

to compensate for some inferior properties of recycled papers, application of processing chemical aids such as chitosan can be quite effective in the wet end section of papermaking. in this study, the performance of chitosan biopolymer, individually or associated with nanobentonite was investigated as wet end additive on recycling process of white cuttings. for this purpose, the performance of ...

forest cover is one of the most effective factors in reducing flooding in northern iran, so that in recent years the destruction, land use changing and uncontrolled harvesting of forest areas, has greatly increased the number and magnitude of floods. so far, there have been few studies on forest hydrology in iran, particularly the northern hyrcanian forests. this study examines the impact of a ...

introduction climate is a system consisting of atmosphere, lithosphere, cryosphere, hydrosphere, and biosphere. this system is involved in the exchange of energy and moisture among these five components. the exchanges link the atmosphere as the central component of the climate to other spheres. changes do not occur separately in this system; rather change in one component contributes to reactio...

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...

evaluation of changes present in soil and water resources due to operation implement of floodwater spreading is necessary to assess their positive or negative resultant effect. rate of the internal sediment to diversion spreader channels, surface sedimentation and aggregation of the spreading field depth are most important effective attributes on the yield of floodwater spreading systems. these...
