we examined the demographic characteristics of couples, ovarian response and sperm quality to determine the predictors of clinical fertilization in ivf cycles. a descriptive and analytic study was conducted using data and biologic specimens obtained fatemeh-alzahra of babol infertility center from 2004 to 2005. only data from 315 women who had medical indication for conventional ivf treatment w...

conclusions by intensive monitoring of the situation of substance abuse among soldiers, commanders can reduce modifiable predictors of suicidal attempt. results the majority of soldiers with mean age of 21.8 (sd = 2.4) years were single (82.1%), employed (54.5%) and had a low level of education or were illiterate (71.1%). in total, 296 (7.5%) soldiers had suicidal attempts in their military ser...

introductionchildren with severe asthma attack are a challenging group of patients who could be difficult to treat and leading to significant morbidity and mortality. asthma attack severity is qualitatively estimated as mild, moderate and severe attacks and respiratory failure based on conditions such as respiration status, feeling of dyspnea, and the degree of unconsciousness. part of which ar...

relationship between grain yield and its component traits can improve the efficiency of breeding programs by determining appropriate selection criteria. an investigation was carried out on barnyard millet (echinochloa spp.) global germplasm collection to investigate the association among yield components and their direct and indirect effects on the grain yield of barnyard millet. the experiment...

the problem discussed in this paper is the effect of latency time on the ogy chaos control methodology in multi chaotic systems. the smith predictor, rhythmic and memory strategies are embedded in the ogy chaos control method to encounter loop latency. a comparison study is provided and the advantages of the smith predictor approach are clearly evident from the closed loop responses. the comple...

in this paper‎, ‎we propose a modification of the second order method‎ ‎introduced in [‎‎q. li and ‎x‎. ‎y. ‎wu‎, a two-step explicit $p$-stable method for solving second order initial value problems‎, ‎textit{‎appl‎. ‎math‎. ‎comput‎.}‎ {‎138}‎ (2003)‎, no. 2-3, ‎435--442‎] for the numerical solution of‎ ‎ivps for second order odes‎. ‎the numerical results obtained by the‎ ‎new method for some...

the purpose of this letter is to revisit the nonlinear reaction-diusion modelin porous catalysts when reaction term is fractional function of the concen-tration distribution of the reactant. this model, which originates also in uidand solute transport in soft tissues and microvessels, has been recently givenanalytical solution in terms of taylors series for dierent family of reactionterms. we...
