بررسی ارزش غذایی تاغ و عمل آوری آن با سود و آهک در مراحل مختلف رشدبا استفاده از روش کیسه های نایلونی
abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
demographic toxicology is a common method for investigation on the sub lethal effects of pesticides on natural enemies. the side effects of plant extracts from root of madder (rubia tinctorum l.), seeds of dill (aniethum graveolens l.) and seeds of galbanum (ferula gummosa boiss.) in comparision with thiamethoxam were evaluated on life table parameters of c. carnea as agonoscena pistaciae preda...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
Sarta longhorned beetle, Aeolesthes sarta, is one of the most destructive wood borer pests of fruit and shade trees in Iran. In this research, the reproductive parameters were studied under laboratory conditions. Fifteen pairs of newly developed adults (1-2 days after emergence from overwintering sites) were caged separately on 15 logs of Ulmus carpinifolia and fertility table was made using th...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
demographic toxicology is a common method for an investigation of the sub lethal effects of pesticides on natural enemies. the present study was conducted to evaluate the side effects of the extracts of calotropis procera (willd.) r. br. (asclepiadaceae), teucrium polium l. (labiatae), fumaria parviflora lam. (fumariaceae) and thymus vulgaris l. (labiatae) in comparison with three pesticides: h...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
hippodamia variegata (goeze) (coleoptera: coccinellidae) is one of the most prominent coccinellid predator of common pistachio psylla, in pistachio orchards. the experiment was performed under laboratory conditions i.e. 27±1oc 55±5 rh and 16:8 l: d. a cohort with about one hundred eggs- less than 24h old- was chosen and put in petri dishes. ladybeetle larvae were daily fed with pistachio psylla...
