OBJECTIVE The study explored the dynamics of shearing force and its correlation with chemical compositions and in vitro dry matter digestibility (IVDMD) of stylo. METHODS The shearing force, diameter, linear density, chemical composition, and IVDMD of different height stylo stem were investigated. Linear regression analysis was done to determine the relationships between the shearing force an...

abstract soil microbial activity and biochemical processes are often limited by carbon availability in arid- and semi-arid regions, probably due to the low organic matter content. consequently, return of plant residues to soil is a convenient and effortless practice for increasing microbial activities and biochemical reactions. the primary objective of this study was to evaluate the effect of v...

background and purpose: essential oils extracted from different plants are extensively used in perfume, beverage, and food industries and are reported to exhibit antimicrobial activities against a variety of fungi. zhumeria majdae belonging to the lamiaceae family is a rare and endemic medicinal plant species in iran, with a strong and pleasant odor. the leaves of this plant have been used for ...

the aim of this study was to investigate the effect of steam treatment on nutritive value of date (phoenix dactylifera) leaves. date leaves were chopped and mixed with water or sulfuric acid solution to contain 50% moisture with or without 1% sulfuric acid. steam treatment of the date leaves was carried out using three levels of steam pressure (14, 17 and 20 bar), three reaction times (120, 180...

five common range forage including agropyron intermedium, bromustomentellus, hordeum bulbosum, cousinia bakhtiarica and scariolla orientalis, weresampled during three phenological stages, from controlled rangeland stations over fivelocations in chaharmahal and bakhtiari province, iran. all samples were chemicallyanalyzed for crude protein (cp%), in vitro dry matter digestibility (dmd), organicm...

plant litter is an important factor for soil conservation and sustainability that could modify soil chemical properties and increase the plant biomass production. the aim of this research was to compare plant litter chemical composition and its effects on soil properties in three species including hordeum bulbosum, poa bulbosa, bromus tectorum. first, soil samples were taken in the depth of 0-3...

biotite samples from different units of boroujerd granitoid complex (bgc) of the sanandaj-sirjan zone, western iran, have beenanalyzed by electron microprobe for major elements. biotite analyses from three units of quartzdiorite, granodiorite and monzograniteof bgc have their own distinct non-overlapping compositional fields in the annite – siderophyllite – phlogopite – eastonitequadrilateral (...

The present paper presents normal values for the contents of water, sodium, potassium, calcium, magnesium, phosphorus,chloride, copper, and iron in peripheral nerves (tibialis, fibularis prolundus, and ulnaris) in individuals without any neurological condition. This study constitutes a basis for the interpretation of other data, still being gathered, relating these normal values with those obta...

The aim of this study was to investigate the effect of inhibition of Marrubium astranicumleaves extract on the corrosion of carbon steel in hydrochloric acid solution by using weightloss and tafel polarization methods. Inhibition was found to increase with increasingconcentration of the leaves extract. The inhibition efficiency of this extract at an optimumconcentration of 100 mg L-1 was 99.9 %...

objective: in order to use natural compounds in controlling plant pests and diseases, many researchers in recent years have studied the antifungal effects of essential oils and plant extracts.  the purpose of this study was to investigate the chemical composition and antifungal effects of echium khuzestanium and marubbium anisodan extracts. methods: after extraction and preparation of different...
