Natural radiation constitute about 97.7% of total radiation dose received by organisms and the remaining comes from nuclear power sector, nuclear tests, medical and miscellaneous. Major contribution to the various radiation exposure received by mankind comes from natural sources.  In the present study distribution and bioaccumulation of Po-210 has been undertaken in Vegetables from Tiruchirappalli City. Samples of carrot, radish, beans, brinjal, tomato, potato, beet root, cabbage, ladies finger and greens are collected and analyzed.

A cytogenetic study was carried out on the chromosomes of pill clam, Pisidium mitchelli (Bivalvia: Veneroida: Pisidiidae) collected from River Chenab fed stream Gho-Manhasan (Jammu, J&K, India). Chromosomes were studied using Giemsa staining and two banding techniques viz. C-banding & Ag-NOR banding. P. mitchelli shows a diploid chromosome number of 2n=62 consisted of seven metacentric, three submetacentric, eighteen subtelocentric and three telocentric chromosomal pairs. The fundamental arm number (FN) was 118.

The present work was focused on analyzing the aerosol optical properties over Rohtak during winter season from December 2015 to February 2016 using sky-radiometer data. The results reveal that AOD shows strong spectral dependence. Higher value of AOD was observed during January at all wavelengths. The monthly mean AOD at 500 nm were found to be 0.44±0.23, 0.80±0.37 and 0.57±0.34 for December, January and February, respectively with seasonal average of 0.63±0.36.

Domestication of Meliponinae in log hive or simple box has often been used in Africa. However, colonyloss in these two hive types due to pest infestation after honey harvesting still occurs. We hypothesized that the two hive types were the probable causes for the infestations.We designed and assessed the hive acceptance andpostharvest colony losses of three Afrotropical Meliponinae namely Plebeina hildebrandti, Meliponula bocandei and two M. ferruginea morpho-speciesin a vertical compartmented hive (called the icipe-4M), as an alternative. We observed that P.

The study was carried out in Dumbriguda Mandal by collecting and analysing the physic- chemical parameters of water samples (four open well, two bore and one spring) during April - October 2015. The results were compared with standards prescribed by WHO and ISO 10500-91.

The present experiment was conducted using 60 genotypes of cowpea to study their correlation and path analysis during kharif-2015. It can be concluded from these experiment findings that main yield contributing traits are biological yield per plant, number of pods per plant, number of flowers per plant, test weight, number of pods per cluster, pod length, number of seeds per pod, number of clusters per plant, harvest index and plant height due to their direct high positive association with seed yield.

The study entitled “to study the constraints experienced by the tribal women participating in decision making in farming” was conducted in Chikhaldara tahsil (Melghat) of Amravati district in Vidarbha Region of Maharashtra State. The study was conducted in ten villages of Chikhaldara Panchayat Samiti From list of 197 villages 10 villages was selected by ‘N’th method of randomization. A list of tribal women from randomly selected villages was prepared. They were arranged alphabetically and thus total 120 tribal women were selected randomly as respondents for the study.

Wetlands provide innumerable valuable services to the society at large such as recharging ground water, recycling nutrients, attenuating floods and as natural habitat supporting various species biodiversity. Due to rapid urbanization and industrialization the only available rain water harvesting wetland of Chennai city, the Pallikaranai marsh land which has been designated as a reserve forest area has been reduced to one-tenth of its original extent due to anthropogenic pressures.

Consumption of contaminated maize poses a significant aflatoxin problem in many countries including Kenya, and many people living in developing countries may be unknowingly chronically exposed to aflatoxin through diet from maize and other cereals. The objective of this study was to determine and compare aflatoxin levels of maize stored households in different altitude areas and in different maize harvest seasons, in Makueni County in Kenya. Design of the study was comparative cross sectional analytical study and setting was in Kibwezi and Kilome sub-counties of Makueni County, Kenya.

Parenting styles are defined as set of attitudes; beliefs and goals parents have and put into practice in their daily interactions with their children. Baumrind (1971) has mentioned three types of parenting styles viz., authoritative/democratic, authoritarian and permissive parenting styles. The present study was under taken to know the parenting styles adopted by mothers of pre-school children.
