the aim of the present study was determination of reference values of blood serum enzymes of huso huso. descriptive study. 18 male and 18 female huso huso was studied. blood samples were obtained from caudal vein of 18 males and 18 females and the levels of enzymes were measured by an autoanalyzer. parametric t- test and pearson correlation test. results of measurements for total samples are as...
abstract this study investigated the predictability of variables from a motivational framework as well as individuals qualities to predict three non-linguistic outcomes of language learning. gardners socio-educational model with its measures has been used in the current study. individual qualities presented in this study include (1) age, (2) gender, and (3) language learning experience. the...
A simple analytical system suitable for nephelometric measurements is introduced in this article. The electronic and optical components are simplified so that the apparatus is easily assembled from materials that are generally available. This instrument is designed for the efficient measurement of anions, and microgram quantities of ions may be determined by a convenient method of titration...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
Non-parametric tests that deal with two samples include scores tests (such as the Wilcoxon rank sum test, normal scores test, log istic scores test, Cauchy scores test, etc.) and Fisher’s randomization test. B ecause the non-parametric tests generally require a large amount of computational work, there are few studies on small-sample properties, although asymptotic properties with regard to var...
the subjects of the study are only the tefl teachers and students at gilan university. to obtain the desired data, a questionnaire which was based on the theories and disecussions gathered, was used as the main data gathering instrument. to determine the degree of relationship between variables, covariance and pearson product moment correlation coefficient were the formulas applied. the data we...
OBJECTIVE To evaluate the possible association between the scale of Alvarado (EA) and macroscopic appearance (MA) of the appendix in patients with acute appendicitis. METHODS after receiving the diagnosis of acute appendicitis, EA data were collected. During appendectomy, MA data were collected. Data from patients without appendicitis were excluded. The Spearman correlation test was used to c...
