treated sea water is the most significant source of water and surfactant floods. the various chemicals employed in treatment plants should be compatible with surfactant systems. based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...

thin films of sno2 nanowires were successfully prepared by using chemical vapor deposition (cvd) process on quartz substrates. afterwards, a thin  layer of palladium (pd) as a catalyst was coated on top of nanowires. for the deposition of pd, a simple and low cost technique of spray pyrolysis was employed, which caused an intensive enhancement on the sensing response of fabricated sensors. prep...

government interventions in agricultural markets in order to stabilize commodity prices and producer incomes have had a long tradition. intervention has been at both the state and country levels and has been for the most part in the form of commodity-based schemes. this study represents an attempt to develop an appropriate methodology for analyzing the aggre-gate effects of a particular type of...

a 42-day study was conducted to evaluate the influence of full-fat flaxseed (fs) and canola seed (cs) on broiler performance, fatty acid (fa) profile of meat, serum lipid content and antibody response to sheep red blood cells antigen (srbc). a total of 324 one-day-old chicks were attributed to 6 experimental groups. c: control (soybean-corn); cs1:7.5% cs; cs2:15% cs; cs-fs:10% fs + 10% cs; fs1:...

this study was conducted to determine the effects of adding ethanol extract of propolis (eep) and cumin essential oil (ceo) to diets of broiler chicks on the performance, blood parameters, immune response and carcass traits. a total of 240 day-old ross-308 broiler chicks were randomly allocated to four treatments with six replicates and 10 birds in each replicate in a completely randomized desi...

objectives: multidrug resistance (mdr), which may be due to the over expression of p-glycoprotein (pgp) and/or mrp, is a major problem in neoadjuvant chemotherapy of osteosarcoma. the aim of this study was to investigate the role of tc-99m mibi scan for predicting the response to pre-operative chemotherapy. materials and methods: twenty-five patients (12 males and 13 females, aged between 8 and...

background: daily increased rate of anterior cruciate ligament (acl) injuries in athletes calls for more investigation in these patients to differentiate copers from noncoper acl-deficient (acld) knees as soon as possible. objectives: the current study aims to introduce a new electromyographic protocol, named voluntary response index (vri), that might help to categorize and differentiate patien...

this study was aimed at investigating the effectiveness of training of pivotal response treatment (prt) to mothers with 6 to 12 year old autistic children on reducing the autism symptoms. also, the impact of prt on reduction of parenting stress was addressed in this study. in a clinical trial work, 14 mothers of autistic children in a rehabilitation clinic for autistic children in tehran city, ...
