A microplot experiment was conducted during kharif and rabi seasons of crop years 2010-12in New Delhi, to study the effect of continuous or cyclic tillage on yield performance and nutrient uptake of wheat in soybean–wheat cropping system. The treatments consisted of conventional tillage (CT) and zero-tillage (ZT),and residue management of soybean residue (SR) and/or wheat (WR).The experiment was laid out in microplots (with the size of 4 x 1 m) in RBD with two replications.

This research on Kalmadu tank aims to analyze the horizontal and vertical profiles of selected water quality parameters. Twenty randomly selected sampling points on surface and corresponding vertical depths of 30 cm and 60 cm were measured for temperature, pH, TDS, EC and ORP using intended electronic probes. The measured values were statistically analyzed with t-test, paired t-test and Pearson correlation. Kriging interpolation technique was used to visualize the spatial distribution. Results revealed non-compliance of TDS and EC with existing permissible limits for irrigable water.

The nanotechnology industry has made a rapid progress by introducing unusual properties to the substances at nano scales. When we look at LC50 values, since prolonged to 96 h than 48 h exposure time, toxic effect  quantities of PVF+, Pd/PVF+  and K2PdCl4 suggest that the necessary amount to show the same toxic effect had diminished and its toxic effect increased quite a great deal in time.

The objectives of this study are to assess the effect of pregnancy (in the third trimester) and pregnancy complicated by hypertension on lipid profile in Sudanese pregnant women. The study was carried out utilizing 120 women, including 40 non-pregnant women and unmarried (control), 40 pregnant women at the third trimester, and 40 women with preeclampsia. Their ages ranged from 17- 38 years. Serum was analyzed for total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride.

Among orchids, Cymbidium, Dendrobium, Vanda, Phalaenopsis, Aerides, Mokara and Paphiopedilum and their related hybrids are highly valued for long lasting cut flowers. The six main techniques used for orchid propagation are division, backbulbs, serial cuttings, kiekies, micro-propagation and seed culture. Conventionally, sympodial orchids like Cattleya, Dendrobium, Paphiopedilum and Cymbidium are multiplied through divisions whereas monopodials viz. Vanda, Aerides, Arachnis, Mokara etc. through cuttings.

Repeated outbreaksof vector-borne diseases necessitateddetailed study on the diversity and abundance of mosquitoes associated withThalassery municipal area, of Kannur district, Kerala, India.Seasonal collection of mosquitoes both in adult and larval forms were carried outfrom heterogeneous habitats of the municipal area to determine the species composition, relative abundance and habitat characteristics. Mosquito larvae collected from temporary and permanent breeding sites were reared to adults in the laboratory for species level identification.

A new thiaazacrown ether derived from naphthalimide was successfully synthesized with high dilution method in high yields. The structure of this new compound was characterized by NMR and MS.

Of the various insect species silk producing  insects  which includes Bombyx mori and Antherae mylitta are very famous as these are highly beneficial to the mankind. They produce silk which is worldwide recognized as the Queen of fibres. The demand of silk is increasing in the world day by day and therefore many scientists are involved to increase the production and productivity of silk by using latest technologies. .

Fibre is a thread like substance used in textile industry for the production of goods or provision of services. Two major groups of textile fibres are natural & synthetic. Natural Fibres are subdivided into animal, vegetable and mineral fibres. All animal fibres are proteins, all vegetable fibres are cellulose, all mineral fibres are mineral based. Eg:-Silk, cotton, wool, linen, jute etc. Natural fibres tend to have complex and distinctive internal and external features. Natural fibres have variable diameter, cross section and possibly color banding.

Entropy and absolute temperature, both involved in Carnot’s cycle, imply that time and social constructivism of thermodynamic processes produce sufficient support for reconciling the threefold time emergence: (i) time as  a 1D manifold, (ii) the asymmetric thermodynamic, and (iii) the evolutionary  asymmetric time. Is time whether emerging from entropy as reality with three  different faces or does it mean that we have to manage three different  realities emerging from heat transformation? We put forward three steps. Firstly, we start from a triad of time.
