Wetlands are one of the most productive ecosystems on this earth exhibiting a large diversity. The importance of wetlands are indicated by the Ramsar Convention. This study deals with the status of two wetlands i.e. Sasthamcottah Lake of Kollam, Kerala and Upper Lake of Bhopal, M.P. which are 'Ramsar Sites'. The paper helps in understanding the use of Remote Sensing and Geographic Information System (GIS) tools in mapping of surface water bodies and wetlands and also assessing the lake capacity. The major elements of this methodology involves the use of IRS LISS III sensors for delineating major geomorphological classes of wetlands. The change in the lake area was detected to be 82.67 Ha in the Sasthamcottah Lake and the capacity was deduced as 32,806.322 M.cu.m. Similarly the lake area change was 453.76 Ha in the Upper Lake of Bhopal with the current capacity to be around 79000.49 M.cu.m. © Research India Publications.

The Rivers including river Yamuna and Ganges in upper reaches of Himalayan Mountains are yet some rivers and rivulets which are unpolluted and pristine. The analysis of physico-chemical Parameters of natural water of tributaries of River Beas in Palampur area of outer Himalayas was done by Following the Standard Methods for Examination of Water & Waste Water for analysis. Range of all the physico - chemical parameters was found within acceptable limits. As a result, water of all three tributaries viz. site I (Poon), Site II (Awa) & Site III (Mole) was found suitable for drinking purpose and will be helpful to solve the problem of drinking water in metropolitan cities. This can be supplied as drinking water after primary treatment at national level and opens up a new scope for starting a bottled water Industry by private organizations, thus will also help in providing employment to the local people of Tribal area where the scope of employment is very limited.

Background: The central Indian state Madhya Pradesh is often called as 'heart of India' and has always been an important region functioning as a trinexus belt for three major language families (Indo-European, Dravidian and Austroasiatic). There are less detailed genetic studies on the populations inhabited in this region. Therefore, this study is an attempt for extensive characterization of genetic ancestries of three tribal populations, namely; Bharia, Bhil and Sahariya, inhabiting this region using haploid and diploid DNA markers. Methodology/Principal Findings: Mitochondrial DNA analysis showed high diversity, including some of the older sublineages of M haplogroup and prominent R lineages in all the three tribes. Y-chromosomal biallelic markers revealed high frequency of Austroasiatic-specific M95-O2a haplogroup in Bharia and Sahariya, M82-H1a in Bhil and M17-R1a in Bhil and Sahariya. The results obtained by haploid as well as diploid genetic markers revealed strong genetic affinity of Bharia (a Dravidian speaking tribe) with the Austroasiatic (Munda) group. The gene flow from Austroasiatic group is further confirmed by their Y-STRs haplotype sharing analysis, where we determined their founder haplotype from the North Munda speaking tribe, while, autosomal analysis was largely in concordant with the haploid DNA results. Conclusions/Significance: Bhil exhibited largely Indo-European specific ancestry, while Sahariya and Bharia showed admixed genetic package of Indo-European and Austroasiatic populations. Hence, in a landscape like India, linguistic label doesn't unequivocally follow the genetic footprints. © 2012 Sharma et al.

Bleachable grade of pulp is produced by sulphate chemical process because reduced pitch troubles with resinuous wood. The stream pollution and air pollution can be minimised by using anthraquinone. In sulphate pulping, the yield and properties of pulp produced are dependent on two sets of variables, with the fibrous raw material and with the pulping operation. The permagnate number and pulp yield are determined by analysis. On addition of anthraquinone in sulphate process, there is no adverse effect but it is helpful in reducing the cost of pulp.
