in the present work, multidimensional modeling of open-cycle process of om355 engine was developed. calculations for computational mesh were carried out. the results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. results included pressure, temperature, emission a...

BACKGROUND The optimal way of assessing the impact of pulmonary rehabilitation on functional status in chronic obstructive pulmonary disease (COPD) is currently unknown. The minimal clinically important difference for the constant work rate cycling exercise test also needs to be investigated to facilitate its interpretation. A study was undertaken to evaluate the changes in the 6-min walking te...

conclusions in this study¸ rosa damascena and mefenamic acid had similar effects on pain intensity of primary dysmenorrhea . with further studies, rosa damascena which has no chemical side effects¸ can be suggested for treating primary dysmenorrhea. results there was a significant difference between the average of pain intensity at different hours of measurement in each group after the end of f...

The ASTM D 1037 six-cycle accelerated-aging test for wood-based panel products was analyzed to determine how each successive aging cycle and selected steps in each cycle contribute to panel deterioration. Hardboard, particleboard, flakeboard, waferboard, and oriented strandboard were evaluated. The rate of panel deterioration generally decreased with each successive aging cycle. Four cycles of ...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...

Background: The premenstrual symptoms may be a sensitive marker of psycho-physiological problems that applied as a diagnostic and a reproductive health education tool and can be influenced different factors such as menstrual characteristics. So, the aim of this study was to evaluate the relationship between premenstrual nausea, vomiting and menstrual characteristics. Materials and Methods: This...

The outcome of Kremer testing has been evaluated daily, during the mid-cycle, in 15 healthy women over three menstrual cycles, using a permanent and a variable normal, male donor. There was a significant correlation (r = 0.539; t = 6.33; P less than 0.001, n = 100; Spearman rank correlation with correction for ties) between the results obtained with the two men. The best Kremer test results wer...
