Rice husk, agricultural waste material of environmental  impact,  was carbonized at temperatures of 300 - 600⁰C in an oven for 2h, after which its adsorption capacities was investigated for the adsorption of acenaphthene in synthetic aqueous solution, at increasing concentrations (50–150mg/L). The yields of carbon obtained from the raw rice husk ranged from 20 - 40 % (w/w), while the adsorption capacities of rice husk increased with increasing carbonization temperature and increasing initial concentration of acenaphthene. The removal efficiencies of the rice husk increased from 71.37 - 80.56% as the carbonization temperature increased from 300 - 600⁰C, but decreased with increasing initial concentration of acenaphthene. The adsorption equilibrium data obtained, fitted well to the Freundlich, Langmuir, Temkin and Dubnin-Radushkevich isotherms with minimum correlation values of 0.9981, 0.9262, 0.9667 and 0.9215, respectively, although, generally decreases with increasing carbonization temperature. The error analysis showed the order of suitability of the isotherm models selected to be Temkin > Freundlich > Dubnin-Radushkevich > Langmuir. This study shows that carbons rice husk possesses high potency of being used as activated carbon for the removal of acenaphthene from wastewater.

The verifications of boundedness and compactness of the weighted composition operators of relations between different Bergman spaces of bounded symmetric domains which are Hilbert are characterized by using Carleson measure. As an application, we study the relations of multipliers between different Bergman spaces

Cellular Manufacturing System (CMS) is an application of Group Technology (GT) in which functionally dissimilar machines are grouped together to form a family of parts. This work gives an overview of the Back Propagation Network (BPN) based approaches to form the machine cells and component grouping for minimizing the exceptional elements and bottleneck machines. This method is applied to the known benchmark problems found in literature, and it is found to be equal or best when compared to in terms of minimizing number of exceptional elements.

We are very happy to announce that from 26th October 2016, Mr.S.Balan has joined the team of Elixir Editorial Advisory Board. He/She will carry a special responsibility for dealing with manuscripts based on Computer Science. The appointment of Mr.S.Balan as member Editorial Advisory Board strengthens the links and will make it easier for prospective authors to establish contact with the journal.

Here, a equilateral triangular shaped circular feed network is designed. This circular feed network can radiate in eight different directions. This radiation is depending on four inputs ports which are excited. It can cover wide area within upper hemisphere. This antenna is designed in such a way that it is useful for any applicable GHz ISM band frequency and utilizes a suspended FR4 substrate. For this antenna we used positive microstrip elements, so that it will make easy to manufacture.

The furthermost impact of the climate change would be displacement of people, leading mass migration at a large scale. The affected communities would be largely from climate vulnerable island nations and also from developing countries which will not have the infrastructure to cope with the climate change induced natural disasters. The main issue here would be the cross-border migration leading to refugee status claims. But the present international refugee law framework governed by the Refugee Convention, 1951 is in no way equipped in dealing with climate refugees. This clearly calls for international co-operation and consensus building for dealing with the climate refugees as a part of the climate change adaptation mechanism. An effective and binding provision in the climate change agreements for tackling climate change induced migration through co-operation is crucial. This paper points out the lacunae in the present international refugee law framework and discusses regarding mitigating this gap and provides pointers regarding the way forward.

In this research, optimization of electromagnetic shielding tester process parameters for conducting textile composite materials through Taguchi design and ANOVA has been reported. The electromagnetic shielding tester process parameters were selected to optimize the EMSE. The effect of the size of the test Conductive Textile Material Composite sample on EMSE, effect of distance between Conductive Textile Material Composite sample and transmitting antenna on EMSE, effect of distance between the Conductive Textile Material Composite sample and receiving antenna on EMSE, and effect of RH% on EMSE were analyzed and optimized by Taguchi design and ANOVA. It was observed that the electromagnetic shielding effectiveness of conductive textile Composite materials were dominantly influenced by Conductive Textile Material Composite sample size and significantly influenced by distance between Conductive Textile Material Composite sample and transmitting antenna.

Organotin compounds have attracted global attention due to their extensive use for agricultural, industrial, medicinal, and domestic applications. These applications have made them enter the environment. This has caused environmental concerns due to the proven toxicological relevance of the compounds. Their toxic effects result in extensive damage to non-target organisms at ultratrace concentration levels (ppt) and accumulation in sediments and biota. This leads to the legislative restriction place on the uses of some of these compounds. Despite the legislative restriction, their environmental pollutions continue. Hence, this review which is aimed at providing an overview of the application of organotin compounds and their environmental toxicities.

Osteoid osteoma is a benign osseous tumor of unknown origin, which affects preferentially the long bones. The localization in the phalanx is unusual and difficult to diagnose. We present a case of a twenty-year-old student, presenting with a painful swelling of the first phalanx of the right second finger of six months duration, not responding to anti-inflammatory drugs. The lesion was excised, and the histology confirmed the diagnosis of osteoid osteoma. Through our observation and after a review of the literature, we analyze the clinical and paraclinical appearance of this uncommon localization, the differential diagnosis, and finally the therapeutic possibilities.

A study on rotifers was conducted to count percentage prevalence from Upper Dudhana dam of Jalna district, Maharashtra, India. Rotifera is major group from zooplankton having divers planktonic forms and they shows variation in occurrence amongst them. Samples were collected fortnightly interval for a period of one year from February 2014 to January 2015 and percentage prevalence was counted. Result indicated that the highest percentage prevalence was showed by Brachionus caudatus (87.5%) whereas lowest by Keratella vulga (20.83%) during the period of sampling. The authors concluded that Brachionus caudatus was persistently present in all the seasons of sampling period. The above study gives information of the status of rotifers and providing new insights into its ecology.
