Aconitum balfourii （Bruhl） Muk. （ranunculaceae） is an en- dangered medicinal plant. Natural populations were surveyed in the northwest Himalaya for population estimation and evaluation of elite germplasm. Vegetation sampling of quadrats was conducted using the vertical belt transect method in areas supporting A. balfourii. Plant den- sity and relative dominance ofA. balfourii were low compared with other alpine species. Threat status was determined on a site-by-site basis as well as for entire western Himalaya..4. balfourii was generally classified as endangered on the basis of geographic distribution and critically en- dangered on the basis of abundance. We found the natural geographic distribution of.4. balfourii to be diminishing due to habitat destruction. Immediate corrective management measur.s.are needed for.s.stainable utilization and long-term conservation of the species in the wild.

In this paper, the effects of viscous and Ohmic heating and heat genera- tion/absorption on magnetohydrodynamic flow of an electrically conducting Casson thin film fluid over an unsteady horizontal stretching sheet in a non-Darcy porous medium are investigated. The fluid is assumed to slip along the boundary of the sheet. similar- ity transformation is used to translate the governing partial differential equations into ordinary differential equations. A shooting technique in conjunction with the 4th order runge-Kutta method is used to solve the transformed equations. Computations are car- ried out for velocity and temperature of the fluid thin film along with local skin friction coefficient and local Nusselt number for a range of values of pertinent flow parameters. It is observed that the Casson parameter has the ability to enhance free surface velocity and film thickness, whereas the Forchheimer parameter, which, is r.s.onsible for the inertial drag has an adverse effect on the fluid velocity inside the film. The velocity slip along the boundary tends to decrease the fluid velocity. This investigation has various applications in engineering and in practical problems such as very large scale integration （VLsI） of electronic chips and film coating.

为了确定我们进一步讨论的范围,我们可以回顾一下托克维尔在《美国的民主》一书中所作的研究。托氏的方法对我们是有益的,因为他的前提和命题接近以文化意义的标准来表现意识形态、社会和政治学的问题。他没有在上个世纪中期的法国和美国之间建立起完全的隔离和对立,对于20世纪末期的印度和美国之间我们也不需要这样做。如果他仍然对美国这个相对地说是个新民族的社会变迁的复杂性敏感的话,那么现在我们对印度必须保持同样的姿态。托氏既不是一个简单的归纳论者,也不是简单地歌颂,他始终坚持他研究的主要论题——美国民主与“平等的进步”。同样,研究印度也必须了解其复杂性和各种干扰。
