Abstract: Temperature is one of the most important factors limiting the production and distribution of olive. Different olive cultivars show diverse responses to low temperature and so, the selection of cold tolerant cultivars is the most effective method to avoid frost damages. The main purpose of this study was to compare freezing tolerance of seven olive cultivars and to investigate the rel...
although inter-variety variability for salt tolerance has been reported in bread wheat plants, little information is available on the genetic control of ion contents and biomass yield under saline conditions. a diallel cross, including reciprocals of two salt tolerant, two moderately tolerant and two sensitive iranian and exotic bread wheat varieties, was analyzed to investigate the inheritance...
Background: Tolerance and dependence to anti-nociceptive effect of morphine restricted its use. Nowadays co-administration of morphine and other drugs suggests diminishing this tolerance. Baclofen is one of the drugs that may be beneficial in the attenuation of tolerance to morphine. Studies have shown that changes in transient receptor potential vanilloid type 1 (TRPV-1) expression during admi...
The problem of finding tolerance intervals receives very much attention of researchers and are widely used in various statistical fields, including biometry, economics, reliability analysis and quality control. Tolerance interval is a random interval that covers a specified proportion of the population with a specified confidence level. In this paper, we compare approximate tolerance interva...
in order to evaluate drought tolerance of chickpea genotypes and identifying the best indices of drought tolerance, the 20 genotypes desi chickpea plus two improved cultivars (kaka and piroz) were tested using a randomized complete block design under two irrigated (non stress) and (stress) conditions. quantitive drought tolerance and susceptibility indices such as stress tolerance index (sti), ...
caffeine, an adenosine a1, a2a, and a2b receptor antagonist, is frequently used as an adjuvant analgesic in combination with non steroidal anti-inflammatory drugs or opioids. the aim of this study was to evaluate the effects of caffeine on preventing the development of morphine tolerance and analgesia in mice. in this study, different groups of mice received morphine (30 mg/kg) + saline (10 ml/...
venturi flumes are measurement structures commonly used in water systems to measure the flow discharge. some of them are not well installed or present some geometrical defects. the objective of this study is to investigate the hydraulic influence of a number of typical wrong installations and geometrical defects of long-throated venturi flumes: significant positive or adverse slopes, humps and ...
Tolerance interval is a random interval that contains a proportion of the population with a determined confidence level and is applied in many application fields such as reliability and quality control. In this educational paper, we investigate different methods for computing tolerance interval for the binomial random variable using the package Tolerance in statistical software R.
blocking antibodies are valuable tools for inhibiting the specific receptor- ligand interactions. the interaction of co-stimulatory molecules on the antigen presenting cells with their ligands on t cells is an essential step for t cell activation. in the present study, the effect of blocking antibody against cd40 on its t cell stimulatory potential is investigated. the dcs (dendritic cells) wer...
