The objective of present work is to study the thermo diffusion effect on an unsteady simultaneous convective heat and mass transfer flow of an incompressible, electrically conducting, heat generating/absorbing fluid along a semi-infinite moving porous plate embedded in a porous medium with the presence of pressure gradient, thermal radiation field and chemical reaction. It is assumed that the permeable plate is embedded in a uniform porous medium and moves with a constant velocity in the flow direction in the presence of a transverse magnetic field. It is also assumed that the free stream consists of a mean velocity, temperature and concentration over which are super imposed an exponentially varying with time. The equations of continuity, momentum, energy and diffusion, which govern the flow field, are solved by using a regular perturbation method. The behavior of the velocity, temperature, concentration, Skin-friction, rate of heat transfer and rate of mass transfer has been discussed for variations in the physical parameters. An increase in both Pr and R results a decrease in thermal boundary layer thickness. However, concentration decreases as Kr, Sc increase but it increases with an increase in both So and δ.

职业技术教育最早被看作是培养产业后备军的途径,后来被看作是提高人力资本构成、生产力和就业的手段,今天,人们又认识到它对人的充分发展具有重要作用.人的发展既是国家发展的手段又是国家发展的目的,发展中国家需要一支有熟练技能和适应性强的劳动大军才能抓住发展机会,然而,发展中国家与发达国家的差距还在继续扩大,部分原因是虽然发展中国家注意到了对人的投资,认识到了职业教育与培训的重要性,但发展速度还太慢.职业教育与培训对于降低失业至关重要,但其作用的充分发挥必须依赖于职业教育与培训自身的改善、政府行为的改善、经济形势的好转和妇女就业领域的扩大等前提条件.

对不育症的检查,首先应检查梅毒病,女方应测风疹抗体、测晨起体温,性交安排在预计排卵日。进一步确定排卵试验包括测定黄体期血浆孕酮浓度,经前期宫内膜活检。输卵管损害可行显微外科手术。配偶因素中不育问题男方约占30～40%,妊娠只能靠供者人工授精。非绝对不育的夫妇中5～15%系由于共同因素。性交后试验异常,应进一步检查。夫妇双方均能找到抗精子抗体,应作精子通过颈管粘液试验。仍有20%夫妇找不出不育症原因,可进行滤泡生长的详细监测,以除外“黄体滤泡不能综合征”。

Background: Studies have revealed a strong link between sleep-related breathing disorders and essential hypertension. However, the trends of sleep-disordered breathing in hypertensive patients have not been analyzed frequently. Methods: In this prospective, single-center and observational study, random patients with systemic essential hypertension, who were visiting GSVM Medical College, Kanpur, India between December 2012 and July 2014, were selected. After obtaining informed consent, patients were analyzed for symptoms of sleep-disordered breathing and Epworth Sleepiness Scale. Subsequently, all patients underwent overnight polysomnography to estimate the events of apnea and hypopnea. Observed data were compared between stage I and stage II hypertensive patients. Results: A total of 51 patients (age: 45.7 ± 13.43 years), comprising 36 stage I hypertensives and 15 stage II hypertensives, were enrolled in the study. About 47% of these patients displayed no symptoms of sleep-disordered breathing. Compared to stage I hypertensives, higher percentage of stage II hypertensives reported excessive day time sleepiness. Sleep latency time and sleep architecture were comparable between stage I and stage II hypertensives. Stage II hypertensives displayed shorter total sleep time and higher snore time than stage I hyper-tensives. Apnea Hypopnea Index (AHI) values increased with the severity of hypertension. Nocturnal oxygen desaturation was present in 25.0% and 53.3% of stage I and II hypertensives respectively. Mean lowest oxygen saturation was lower and the mean C-reactive protein levels were higher in stage II hypertensives as compared to stage I hypertensives. The mean C-reactive protein levels increased with increasing AHI scores, while the mean lowest oxygen saturation decreased with increasing AHI scores. Conclusion: Almost half of the hypertensives patients reported no symptoms of sleep-disordered breathing. Sleep-disordered breathing was more common and was more sever

A synthetic method was developed to chemically attach few molecules of simple sugars like glucose, mannose, galactose, maltose and xylose (0.09 - 0.37 wt%) and with quaternary nitrogen pendants (0.42 - 0.46 atomic%) along the polybutadiene section of polystyrene-block-polybutadiene-block-polystyrene (SBS) block copolymer. These functionalized SBS copolymers were evaluated for biodegradation using the fungal culture Aspergillus niger NCIM 1025 (ATCC 9642) and bacterial culture Pseudomonas sp. NCIM 2220, and for antimicrobial properties using bacteria E. coli DH5α and Bacillus subtilis and yeasts Pichia stipitis NCIM 3497 and P. stipitis NCIM 3499. It was conclusively demonstrated that these modified SBS block copolymers were significantly more biodegradable than the unmodified SBS;the observed weight loss after biodegradation was ~4 - 14-fold for bacterial and ~7 - 36-fold for fungal cultures with respect to the sugar content of modified SBS. Preliminary studies on antimicrobial properties of these biodegradable polymers showed a 4% - 24% decrease in growth of the microorganisms E. coli and Bacillus subtilis studied.

Co0.7Me0.3Fe2O4 (Me = Zn, Ni and Mn) were synthesized through co-precipitation method. Cationic distribution for these ferrites was proposed on the basis of magnetization measurements and available occupancy of the substituent ions into the spinel lattice. Theoretical lattice constant calculations confirm the proposed cationic distributions were the correct ones.
