| 1 | Optimization of process parameters of aluminum alloy AA 2014-T6 friction stir welds by response surface methodology显示文摘The heat treatable aluminum-copper alloy AA2014 finds wide application in the aerospace and defence industry due to its high strength-toweight ratio and good ductility. Friction stir welding(FSW) process, an emerging solid state joining process, is suitable for joining this alloy compared to fusion welding processes. This work presents the formulation of a mathematical model with process parameters and tool geometry to predict the responses of friction stir welds of AA 2014-T6 aluminum alloy, viz yield strength, tensile strength and ductility. The most influential process parameters considered are spindle speed, welding speed, tilt angle and tool pin profile. A four-factor, five-level central composite design was used and a response surface methodology(RSM) was employed to develop the regression models to predict the responses.The mechanical properties, such as yield strength(YS), ultimate tensile strength(UTS) and percentage elongation(%El), are considered as responses. Method of analysis of variance was used to determine the important process parameters that affect the responses. Validation trials were carried out to validate these results. These results indicate that the friction stir welds of AA 2014-T6 aluminum alloy welded with hexagonal tool pin profile have the highest tensile strength and elongation, whereas the joints fabricated with conical tool pin profile have the lowest tensile strength and elongation. | Ramanjaneyulu KADAGANCHI Madhusudhan Reddy GANKIDI Hina GOKHALE | 2015 | Defence Technology(防务技术)2015，11，3： | 7 |
| 2 | Carbon stock estimation for tree species of Sem Mukhem sacred forest in Garhwal Himalaya, India显示文摘Carbon stock estimation was conducted in tree species of Sem Mukhem sacred forest in district Tehri of Garhwal Himalaya, Uttarakhand, India. This forest is dedicated to Nagraj Devta and is dominated by tree species, including Quercus floribunda, Quercus semecarpifolia and Rhododendron arboreum. The highest values of below ground biomass density, total biomass density and total carbon density were (34.81±1.68) Mg·ha-1, (168.26±9.04) Mg·ha-1 and (84.13±4.18) Mg·ha-1 for Pinus wallichiana. Overall values of total biomass density and total carbon density calculated were 1549.704 Mg·ha-1 and 774.77 Mg·ha-1 respectively. Total value of growing stock volume density for all species was 732.56 m3·ha-1 and ranged from (144.97±11.98) m3·ha-1 for Pinus wallichiana to (7.78±1.78) m3·ha-1 for Benthamidia capitata. | Nazir A.

| 3 | Inflammation and dry eye disease——where are we?显示文摘The presence of inflammation in dry eye disease(DED)results in increased patient symptomatology,ocular surface damage and worsening tear dysfunction.It also affects the health of meibomian glands and their secretions which further aggravates ocular surface disease.This article reviews current knowledge regarding ocular surface inflammation in DED and explores the relationships between the vicious cycles of DED,inflammation and meibomian gland dysfunction(MGD).The clinical evaluation of eyes with such changes,markers that identify the presence of inflammation on the ocular surface and current treatment options are discussed. | Srinivas K Rao Rishi Mohan Nikhil Gokhale Himanshu Matalia Paras Mehta | 2022 | International Journal of Ophthalmology(English edition)2022，15，5： | 4 |
| 4 | Diversity and regeneration status of Sarkot Van Panchyat in Garhwal Himalaya, India显示文摘We investigated the floristic composition, phytosociological and regeneration status of Sarkot Van Panchyat (community forest) in Chamoli district of Garhwal Himalaya. A total of 52 plant species of 46 genera and 26 families were recorded, which included 12 trees, 18 shrubs and 22 herb species. Quercus leucotrichophora was dominant tree species in sapling and seedling layers, followed by Lyonia ovalifolia and Rhododendron arboreum.Out of 12 tree species, 7 species in seedling stage and 8 species in sapling stage were recorded in the study area. The 44.41% species in the study area showed good regeneration status, 16.66% species were fairly regenerating,and 8.33% species showed poor regeneration status, while 33% species were not regenerating. Number of individuals from lower girth classes (0 10 cmand 10 30 cm) showed decreasing trend with the increase in size of girth class. Shannon index (H) for trees, shrubs and herbs was recorded as 1.82,2.24 and 2.41 respectively. Simpsons index (CD) was recorded as 0.21, 0.12and 0.12 for trees, shrubs and herbs respectively. The forest should be divided into compartments for better management purpose and each compartment should be closed for five years to assist regeneration and enrichment planting may also be carried out for sustainable management. | Nazir A.Pala A.K.Negi Yogesh Gokhale Jahangeer A.Bhat N.P.Todaria | 2012 | Journal of Forestry Research2012，23，3： | 4 |

| 6 | 化学机械抛光中的颗粒技术显示文摘多层金属化是集成芯片以摩尔定律的速度更替的重要工艺手段。在多层金属化中,平坦的晶圆表面对每道工序的成功完成都是非常必要的,而化学机械抛光工艺能在每道工序之前将晶圆表面抛光。化学机械抛光主要是通过使用颗粒研浆去除材料来实现晶圆抛光。除了研浆本身的化学性质外,研浆的效果也受研磨颗粒性质的影响。如果我们能够更好的理解研磨颗粒的特性和颗粒研磨机制,将会有助于提高化学机械抛光效果。本文主要讨论了颗粒形成、研浆稳定性、颗粒润滑以及化学机械抛光中颗粒设计中的最新进展。 | Kalyan S.
