The paper analyses Vesna Parun’s humorous literature - satirical poetry and short forms such as aphorisms epigrams from the perspective of recent theoretical elaborations humour comic. interpretation is based on presumption that author’s poetic a kind political event can put pressure power systems in various areas human life. It encourages readers to question supposedly unquestionable worldview...
background: we investigated whether the lungheart ratio parameter (lhr) can be used to identify the optimum cut off frequency for butterworth filter in 99mtc myocardial spect imaging. materials and methods: this study involved a cardiac phantom system consisting of cardiac insert in which 1.10 cm cold defect was inserted into its myocardium wall and filled with 4.0 μci/ml (0.148 mbq/ml) 99mtc c...
Background and Aim: Vitamin D has a basic role in bone development and metabolism. Regarding high prevalence of vitamin D deficiency in Iran, we aimed to investigate its point prevalence in Arak, Iran and determine a cut-off point for vitamin D deficiency in the region. Materials and Methods: In a cross-sectional study,420 adolescents (220 girls, 200 boys) aged 10-16 years old were selected usi...
abstract to evaluate the effects of the irrigation termination in different growth stages on yield and its components of autumn’s canola cultivars in isfahan region. an experiment was conducted in 2005-2006 in kabotar abad research station. a split plot layout within a randomized complete block design with tree replication was used. main plots were seven level of the irrigation cut-off time (d1...
Background: Brucellosis is a world-wide disease, which has a diverse clinical manifestation, and its diagnosis has to be proven by laboratory data. Serum agglutination test (SAT) is the most-widely used test for diagnosing brucellosis. The enzyme linked immunosorbent assay (ELISA) can also determine specific antibody classes against brucella. It is a sensitive, simple and rapid test, which coul...
مقدمه : تشخیص انفارکتوس میوکارد تا حد زیادی بستگی به مارکرهای بیوشیمیایی دارد. هدف این مطالعه بررسی حساسیت و ویژگی فعالیت ck-mb در تشخیص انفــارکتوس میوکارد می باشد. با توجه به اینکه در کتب رفرنس توصیه شده است هر آزمایشــگاهی cut off تشخیصــی خود را با توجه به تفــاوت هایی که در شرایط آزمایشگاه و جمعیت منطقه وجود دارد تعیین کند و فعــالیت ck-mb از اسفند ماه 81 در بیمارستان حضرت ولی عصر (عج) اند...
Extended Abstract. Sampling is the process of selecting units (e.g., people, organizations) from a population of interest so that by studying the sample we may fairly generalize our results back to the population from which they were chosen. To draw a sample from the underlying population, a variety of sampling methods can be employed, individually or in combination. Cut-off sampling is a pr...
Abstract: A two-dimensional fully implicit finite difference model, which can be easily extended to three dimensions, is developed to study the effect of cut-off walls on saltwater intrusion into the aquifers. This model consists of a coupled system of two nonlinear partial differential equations which describe unsteady density-driven groundwater flow and solute transport. The numerica...
Wheat grain yield reduction occurs in most wheat growing regions of Iran due to post-anthesis water stress. This research was conducted to evaluate yield and yield components of wheat cultivars in normal irrigation and post anthesis irrigation cut-off conditions as a split-plot arrangement based on a randomized complete block design with three replications during 2015-16 in College of Agricultu...
background: brucellosis is a world-wide disease, which has a diverse clinical manifestation, and its diagnosis has to be proven by laboratory data. serum agglutination test (sat) is the most-widely used test for diagnosing brucellosis. the enzyme linked immunosorbent assay (elisa) can also determine specific antibody classes against brucella. it is a sensitive, simple and rapid test, which coul...
