in order to study drought tolerance indices and to introduce tolerant maize hybrids in drought conditions, an experiment was conducted at the experimental field of seed and plant improvement institute, in 2009. the experiment was carried out using split-plot in a randomized complete block design (crbd) with three replications. the main plots consisted of three levels of irrigation regimes (irri...

Several indices of ventilatory heterogeneity can be identified from the expiratory CO2 partial pressure or CO2 elimination versus volume curves. The aims of this study were: 1) to analyse several computerizable indices of volumetric capnography in order to detect ventilatory disturbances; and 2) to establish the relationship between those indices and respiratory system mechanics in subjects wit...

Objective: Iron deficiency anemia (IDA) and beta-thalassemia trait (ß-TT) are the most common forms of microcytic anemia. This study was conducted to compare the validity of various discrimination indices in differentiating β-TT from IDA by calculating their sensitivity, specificity and Youden's index. Methods: Totally 323 subjects (173 children and 150 adults) with microcytic anemia were invol...

BACKGROUND AND OBJECTIVES: Understanding the importance of surface electromyography as a complementary method to understand the myofunctional status of the stomatognathic system, this study aimed at analyzing the frequency of altered and normal electromyographic indices in a sample of subjects with temporomandibular disorders, in addition to their relation with pain complaint. METHODS: Particip...
