drought resistance is a very important characteristic needed for plant survival especially at germination stage, in arid and semi-arid lands. phosphatase enzymes are widely found in plants. these enzymes are responsible for dephosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted in two bread wheat cultivars (sardari and alvand) under s...

ruminal, post-ruminal and total tract crude protein disappearance of alfalfa hay and barley grain were measured using in vivo, in situ mobile bag and three-step in situ/in vitro enzyme procedures (3-step). for in vivo, four baluchi lambs (49.4 ± 3.5 kg, body weight) were used in a 2 × 2 latin square design within 2 periods (24 days of each period). experimental diets were made of two alfalfa ha...

growth irregularity and yield reduction in some transplanted rice growing area treated with thiobencarb (tb) has been reported particularly if tb is applied in non-flooded conditions, without any more information. this experiment was carried out in order to study the effect of time of herbicide application and time of flooding on response of rice and weeds to tb doses. the experiment was laid o...

in the present study, under typical management conditions of dairy farms in iran, the effect of oral administration of on serum glucose, ast and arginase(indices of liver injuries) of oral monensin was assessed. thirteen multiparous holstein cows were blocked into a control and an experiment group from 3 weeks prepartum to 45 days postpartum according the number of their calvings. the groups re...

the current study aimed to investigate the status of harakat journal from its first volume (summer, 1378, no. 1) to the last one (winter, 1368). descriptive research method was used. the statistical population included 338 published papers in 34 harakat journals, and the statistical sample was equal to the statistical population. the data analysis identified 338 papers (average of 9.94) for eac...

this paper is mainly focusing on the determination of mean molal activity coefficient of hcl in aqueous acidic medium. the present investigations have been carried out to determine the activity coefficients of hydrochloric acid in 2-propanol water mixture solutions under various conditions to study the ion solvent interactions in different temperatures. the standard molar potential em0 of the c...

retention behavior of molecules mostly depends on their chemical structure. retention data of biologically active molecules could be an indirect relationship between their structure and biological or pharmacological activity, since the molecular structure affects their behavior in all pharmacokinetic stages. in the present paper, retention parameters (rm0) of biologically active 1,2-o-isopropyl...
