The chemical reaction effect on an unsteady magnetohydrodynamic （MHD） flow past a semi-infinite vertical porous plate with viscous dissipation is analyzed. The governing equations of motion, energy, and species are transformed into ordinary differential equations （ODEs） using the time dependent similarity parameter. The resultant ODEs are then solved numerically by a finite element method. The effects of various parameters on the velocity, temperature, and concentration profiles are presented graphically, and the values of the skin-friction, Nusselt number, and Sherwood number for various values of physical parameters are presented through tables.

A 16-year-old man had aswelling over the anterior aspect of the proximal third of the tibia for 1 year, which was peanut size initially and progressively increased to its present size of 10 cm × 8 cm. He underwent fine needle aspiration cytology(FNAC) twice during this period and reported aspindle cell sarcoma. Malignant peripheral nerve sheath tumor(MpNST) is a malignancy of the connective tissue surrounding the nerves. previously, MpNST was also known as neurofibrosarcoma, malignant schwannoma, andneurogenic sarcoma. We are reporting this case for its rarity and peculiar mode of presentation. FNAC/core biopsy can be used as an effective tool to achievethe correct pathological diagnosis.

Lithiumization of the vacuum vessel wall of the Aditya tokamak using a lithium rod exposed to glow discharge cleaning plasma has been done to understand its effect on plasma performance. After the Li-coating, an increment of ~100 ev in plasma electron temperature has been observed in most of the discharges compared to discharges without Li coating, and the shot reproducibility is considerably improved. Detailed studies of impurity behaviour and hydrogen recycling are made in the Li coated discharges by observing spectral lines of hydrogen, carbon, and oxygen in the visible region using optical fiber, an interference filter, and pMT based systems. A large reduction in O I signal （up to ~40% to 50%） and a 20% to 30% decrease of Ha signal indicate significant reduction of wall recycling. Furthermore, vUv emissions from O v and Fe Xv monitored by a grazing incidence monochromator also show the reduction. Lower Fe Xv emission indicates the declined impurity penetration to the core plasma in the Li coated discharges. Significant increase of the particle and energy confinement times and the reduction of Zeff of the plasma certainly indicate the improved plasma parameters in the Aditya tokamak after lithium wall conditioning.

森林的水土保持作用已被恰当承认。本文按新的观点,即从减轻空气污染方面考察了森林的作用,同时提出一汾耐污染的树种名录。森林是一个具有生命的复杂群居结构的生物群落。它在水土保持方面起着决定性的作用。它们通过蒸腾作用过程,从地上提升水分并释放到大气中去,由于大气水分的凝聚作用而产生雨,并如此循环不断。在生态系统中,在低量污染的情况下,生态系统的植被和土壤,起着降低空气污染的作用。在中度污染时,个别树种或特定树种的单株林木会产生养分效应,削弱新陈代谢,易受昆虫感染或出现病理现象,或直接诱发病害。但是,当污染程度高时,就会导致特定树种的严重病态或死亡。洁净的空气对于任何生物体的生存是不可缺少的。地球大气层是气体、水蒸气、固体微粒和液态微滴的混合物。空气污染的定义是指在大气层里的固体、液体和气体物质的浓度足以伤害人类和动植物的生命或特性。空气的组成在地球各处是不尽相同的。空气污染不仅限于城市,也不仅是由人类的活动而引起。火山爆发,森林火灾,大风所刮起的灰尘、花粉和其它悬浮微粒以及诸如细菌和病毒等另一些活微粒,都能污染空气。近三亿 t 空气污染物质散发到空气中去,这大大超过自然系统安全吸收的水平。当人类学会用火时空气污染就开始了。但大规模的空气污染是与近代工业的发展相关的,此外,就产生污染物的活动性质来说,散发到空气中去的都是在人口稠密的地区。因此,其影响即使在全球规模上是小的,但对局部则可能是严重的。据估计,由于大量二氧化碳加入到大气层里,使地球平均温度提高6℃,这可能会造成地球过去7000万年从未经历过的气候情况。即使实际增加的温度较预期的小,但也足以溶化大量极地冰和提高海平面5m。同样,同温层的臭氧能有效地阻挡大量从各方面传到地球表面的有害的太阳紫外辐射线。目前的计算表明,臭氧层的16.5％将会由于人类制造化学药品而消失。毁灭臭氧的半数(近8％)将发生于今后30年内(Khoshoo 和 Ahmad,1981)。工业和都市社团经常散布对周围人类和其它活生物体有害的污染物质。这些污染物质包括放射性尘埃、盐雾、除草剂和农药、大气微粒、烟尘、矿石冶炼、煤的燃烧、制砖、制陶瓷、制水泥、制玻璃、制磷肥、酸物质液滴、煤气和某些时候的土壤微粒。这些物质对一切生物都可以单独起刺激作用,或者它们可能联合起来,对环境起更为有害的不利作用。最近苏联的切尔诺贝尔核电站的火灾并随之而发生的放射性泄漏,对发达国家和发展中国家来说,是一个突出的实例和警告信号。

Depth-duration analysis, such as accomplished for rainfall, can be useful in the analysis of infiltration of rainfall. The assessment of infiltration depth-duration in terms of return frequency is of interest. In this paper, depth-duration values of daily rainfall infiltration are estimated using the National Resources Conservation Service (NRCS) Curve Number (CN) approach for estimating daily runoff. The CN methods may be generally applicable to soils that are free draining. From the estimated history of daily infiltration, a depth-duration analysis is accomplished for all duration sizes from 1 day to 365 days. These annual outcomes are then analyzed as to a possible underlying probability distribution. For the rain gages considered, the depth-duration infiltration estimates (using the CN approach) appear to be normally distributed. From the fitted distribution, estimates of rare events of rainfall infiltration may be made, and possible linkage to earth movement events accomplished with respect to return frequency of infiltration, which in turn can aid in the design and risk assessment of fixed works involving soil water accumulation.

A cup-shaped component of Mg-4 Al-2 ba-2 Ca（Aba X422） alloy was forged in the temperature range of 300-500 °C and at speeds in the range of 0.01-10 mm/s with a view to validate the processing map and study the microstructural development. The process was simulated through finite-element method to estimate the local and average strain rate ranges in the forging envelope. The processing map exhibited two domains in the following ranges：（1） 300-390 °C and 0.0003-0.001 s^-1, and（2） 400-500 °C and 0.0003-0.3 s^-1 and both represented dynamic recrystallization（DRX）. The map revealed a wide flow instability regime at higher strain rates and temperatures lower than 400 °C, in which flow localization occurred. Forgings produced under conditions of the above two domains were sound and symmetrical, and had finer grain sizes when being forged in the first domain. However, when being forged in the flow instability regimes, the alloy fractured before the final shape was reached. The experimental load-stroke curves for the conditions within the domains correlated well with the simulated ones, whereas the curves obtained in the instability regime were uneven.

The effect of Sn, Ca, Al, Si and Zn addition on the compressive strength of cast Mg-Sn-Ca （TX） alloys was studied in the temperature range of 25-250 °C and correlated with the microstructure. The Sn to Ca mass ratio up to 2.5 contributes to the formation of Mg2Ca phase at the grain boundaries and CaMgSn in the matrix, while a ratio of 3 gives only CaMgSn phase mostly in the matrix. While the compressive strength decreases with the increase in temperature, for Sn/Ca up to 2.5, a plateau occurs in 100-175 °C, which is attributed to the strengthening by Mg2Ca. However, for ratio of 3, the strength is lower and decreases more gradually. Mg-3Sn-2Ca （TX32） has the highest strength and the addition of 0.4%Al increases its strength but simultaneous addition of Si lowers the strength. Likewise, the addition of Zn improves its strength but simultaneous addition of Al slightly decreases the strength. The results are correlated with the types of intermetallic phases that form in various alloys.
