Densities and speeds of sound and their excess properties for 1-butyl-3- methylimidazolium Hexafluorophosphate (Bmim) (PF6) with 1-Butanol over the entire range of mole fraction are reported at temperature 303.15 K and atmospheric pressure. Isentropic and excess isentropic compressibility for ionic liquid with 1-Butaanol were calculated from the experimental results. The excess values are fitted to the Redlich−Kister polynomial equation to estimate the binary coefficients and standard error between the experimental and calculated values.

The basic structure of melatonin is evolutionarily conserved. Hence, it was speculated that melatonin may be present in different animals (from unicellular to multi-cellular) and even in plants. Melatonin in plans is generally regarded as phyto-melatonin. Like the role of melatonin in animals, phyto-melatonin can perform a number of functions like attenuation of apoptosis, prevention of free radical generation, protection against UV irradiation etc. But, unlike phyto-estrogen, the role of phyto-melatonin in animals is totally an unexplored area.

Bivalent transition metal [Co(II), Ni(II), Cu(II) and Zn(II)] complexes with 2,4-dihydroxybenzaldehyde-2-picolylamine(BAPA) are synthesized and analyzed based on mass spectra, molar conductivity, FT-IR and UV-Vis spectral data. The complexes are found to be non-electrolytes. From FT-IR data it is evident that the BAPA acts as uni-negative tridentate ligand. Electronic spectral data confers octahedral structure for the complexes. The copper complex is also studied using ESR spectroscopy. The Spin Hamiltonian, orbital reduction and bonding parameters are determined for the complex.

The effect of Salicylic Acid (SA) on the shoot growth (length, fresh weight, diameter, and dry weight) root growth (length, fresh weight, diameter, and dry weight) and foliar growth (plant fresh weight, leaves per plant and leaf area) of bajra plants grown in the drought stressed Telangana State was studied. Telangana State is a semi –arid tropic comprising of saline land black soil wherein the plants usually experience drought and saline stresses.

Serendipity is known as the way great researches are done. The present methodology involves Solanum xanthocarpum used in natural form to act potentially antiviral. The said biological herb is rich in glycoalkaloids like solasodine, solasonine and solamigrine etc. The active ingredients are present throughout all parts of plant but for convenience sake, accuracy and efficacy, only ripe and near ripe berries are used which are then dried as per the pharmacognosial recommendations, powdered and packed airtight away from moisture, heat or direct sunlight.

Solid state nuclear track detectors (LR-115, type II) were used to measure the radon (222Rn) emanation coefficient in some building materials and internal hazards associated with exposure of alpha particles in Shahjahanpur District of Uttar Pradesh. For the same measurement, cylindrical can technique was used containing LR-115, type II plastic detector.

The aim of this study was to dissect the response of melatonin under different mode of application with series of concentrations in pea plants for growth, photosynthesis and antioxidant system. Surface sterilized seeds of Pisum sativum were soaked in deionized water (control), 50, 100, and 200 M of melatonin for 4, 8, and 12 h (shotgun approach). In another mode of application, same concentrations of ML applied through foliage of plants and were allowed to grow for 30 days.

Natural dyes are currently in demand not only in textile industry but in cosmetics, leather, food and pharmaceuticals. The rich biodiversity of India has provided the large amount of raw materials for natural dye extraction. Natural dyes show better biodegradability and are generally more used to with the environment. They are derived from natural resources; like plants, animals, minerals, and microbes. The majority of natural dyes need a mordanting agent (metal salt or tannins) to create an attachment between the cloth and dye.

Few Ruthenium complexes were synthesized. The structures of these complexes are characterized from XRD and spectroscopic techniques. Furthermore computational technique was used to complement the experimental structures. Three complexes were synthesized and assessed the structures of these. UV-visible titration experiment showed the binding of these complexes with CT-DNA. Antimicrobial activity of these complexes was also studies, but Ru-AT and Ru-ANP complexes are found to be good activity and Ru-ATDM complex showed no activity.

Street vending foods are readily available sources of meals for many people, but the microbiological qualities of such foods have been always in doubt. The aim of this study was to determine the microbial quality of legume and vegetable based foods and the hygienic practices of street vendors in Bahir Dar town. Sixty (60) food samples were collected from different locations. Aerobic mesophilic, total coliforms, fecal coliforms and Staphylococcus aureus counts was based on standard methods from between July 2015 and December 2015.
