People and plant: Learning with Adi community on ethnomedicinal practices and conservation in Arunachal Pradesh, India
74-82Local plant species have been in use in variety of ethnomedicinal practices from the time immemorial among the people of various communities for treating various human diseases. This paper reports about the plant species used by Adi community in curing various human diseases and ailments. A study was conducted during 2008-2009 and further refined in succeeding years with the 12 purposively selected traditional knowledge holders (TKHs) of Adi tribe of East Siang district, Arunachal Pradesh, India. Data were collected using combined approaches of personal interview, participant observations and transect walks. It was observed that with Shannon-Weaver diversity index 2.73, there were 39 local plant species belonging to 25 plant families and used as ethnomedicinal practices by the TKHs. Most of the species (17) were used by Adi TKHs with their green leaf parts followed by root and fruits (5 each) to develop ethnomedicinal formulations. Out of these, several species namely Leucas aspera (Willd.) Link.; Plumeria rubra L.; Catharanthus roseus (L.) G. Don; Solanum torvum Swartz; Solanum khasianum C.B. Clarke; Oroxylum indicum (L.) Benth.ex Kurze; and Tinospora cordifolia (Thunb.) Miers) were found in use by Adis against asthma, bronchitis, cough, sinusitis, diabetes, malaria, typhoid and jaundice. The Adi TKHs maintain a rich cultural ethics, govern by their own world-view in continuing ethnomedicinal practices, and harvesting the species from various land use systems with the aim to sustain biodiversity and associated practices. The key findings indicated that, plant species used as ethnomedicines for some of the diseases and ailments by the Adi TKHs, can be undertaken for the long-term trial to find some natural remedies against few human diseases, including search of immune enhancer against COVID-19, provided TKHs of Adi community are partnered in ethically and culturally appropriate manner.

A Microsatellite Guided Insight into the Genetic Status of Adi, an Isolated Hunting-Gathering Tribe of Northeast India
Tibeto-Burman populations of India provide an insight into the peopling of India and aid in understanding their genetic relationship with populations of East, South and Southeast Asia. The study investigates the genetic status of one such Tibeto-Burman group, Adi of Arunachal Pradesh based on 15 autosomal microsatellite markers. Further the study examines, based on 9 common microsatellite loci, the genetic relationship of Adi with 16 other Tibeto-Burman speakers of India and 28 neighboring populations of East and Southeast Asia. Overall, the results support the recent formation of the Adi sub-tribes from a putative ancestral group and reveal that geographic contiguity is a major influencing factor of the genetic affinity among the Tibeto-Burman populations of India
Salt Dependence of the Tribological Properties of a Surface-Grafted Weak Polycation in Aqueous Solution
The nanoscopic adhesive and frictional behaviour of end-grafted poly[2-(dimethyl amino)ethyl methacrylate] (PDMAEMA) films (brushes) in contact with gold- or PDMAEMA-coated atomic force microscope tips in potassium halide solutions with different concentrations up to 300Â mM is a strong function of salt concentration. The conformation of the polymers in the brush layer is sensitive to salt concentration, which leads to large changes in adhesive forces and the contact mechanics at the tipâsample contact, with swollen brushes (which occur at low salt concentrations) yielding large areas of contact and frictionâload plots that fit JKR behaviour, while collapsed brushes (which occur at high salt concentrations) yield sliding dominated by ploughing, with conformations in between fitting DMT mechanics. The relative effect of the different anions follows the Hofmeister series, with I â collapsing the brushes more than Br â and Cl â for the same salt concentration

Providing a computing environment for a high energy physics workshop
Although computing facilities have been provided at conferences and workshops remote from the host institution for some years, the equipment provided has rarely been capable of providing for much more than simple editing and electronic mail. This report documents the effort involved in providing a local computing facility with world-wide networking capability for a physics workshop so that we and others can benefit from the knowledge gained through the experience
Poor health, low mortality? Paradox found among immigrants in England and Wales
The 'healthy immigrant effect' and 'migrant mortality advantage' describe the better health and lower mortality of international immigrants as compared with the nativeâborn populations of highâincome countries. However, a growing body of evidence suggests that it is much more common to observe low mortality among immigrants than it is good health, pointing to the existence of a potential paradox that mirrors the wellâknown gender paradox in health and mortality. To investigate this, we used the Office for National Statistics Longitudinal Study, a largeâscale representative 1% sample of the England and Wales resident population comprising linked individualâlevel health, mortality, and socioâdemographic data. We compared health and mortality within and across major immigrant groups over 20 years using logistic regression for health and discreteâtime survival analysis for mortality, both before and after adjusting for socioâdemographic factors. Of the eight origin subgroups studied, we found persistent evidence of a healthâmortality paradox within three: men and women from India, Pakistan and Bangladesh, and the Caribbean. We discuss potential explanations and implications of this paradox and suggest that decision makers need to react to help these subgroups preserve their health in order to delay the onset of limiting illnesses and emergence of this paradox
