introduction : in the recent years, due to the wide spread of resistant bacteria on one side and several different reports about the side effects of chemical drugs on the other side, vast researches on the medicinal plants have been started. in this study, antimicrobial effect of total extract of tribulus terrestris l . and its fraction containing benzoxazine derivative (terresoxazine) was stud...

ABSTRACT- Efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. This research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (WP) with different water management scenarios at farm level at ...

The aim of this review was to evaluate the effect of different preparations of garlic with different methodologies on prevention and control of cardiovascular disorders. Almost 30 articles and abstracts from 1990-2003 were searched through Medline. Most of the studies between 1990-1993 showed the significant reduction of TC by garlic powder but a recent controlled study in 2000 found that consu...

Objective: In the present work, the effects of different fractions of Coriandrum sativum (C. sativum), on pentylenetetrazole (PTZ)-induced seizures and brain tissues oxidative damage were investigated in rats. Materials and Methods: The rats were divided into the following groups: (1) vehicle, (2) PTZ (90 mg/kg), (3) water fraction (WF) of C. sativum (25 and 100 mg/kg), (4) n-butanol fraction (...

Norway spruce (Picea abies) debarking water is an aqueous extract obtained as waste from the debarking of logs at paper mills. The debarking water contains a mixture of natural compounds that can exhibit diverse biological activities, potentially including fungicidal activity on some species of wood-decaying fungi. Thus, we investigated the growth rates of such fungi on agar plates to which deb...

many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (asf) of such systems. in this paper, the behaviour of integrating the phase change material (pcm) in sdhw systems is modelled and optimized numer...

measurement of availability and mobility of heavy metals in river sediments is required in order to understand the behavior of these metals and to prevent potential toxic hazards. leaching column experiments were conducted for four sediment samples to determine the degree of mobility and the distribution of zn, cd, ni, cu, and pb because of an application of spiked heavy metals in sediments. se...

In the present paper, the effect of water-CuO nanofluid on the radiator heat transfer of an automobile, Peugeot 405 XU7 engine type is investigated experimentally. The experiments are carried out for the radiator water (water-ethylene glycol with a volume fraction of 80-20, respectively) as a base fluid and water-CuO nanofluid with the volume fraction of 0.5% and 1%. Sodium Dodecyl Sulfate (SDS...
