Evaluation of effect of gamma rays on sesame genotype TTVS 51 and TTVS 19 in M1 generation

Sesame (Sesamum indicum L. syn. S. orientale Linn.) genotypes TTVS 51 and TTVS 19 was exposed to variable doses of gamma rays to study their consequence on several characters like plant height, number of branches, days to 50% flowering, Number of capsule per plant, thousand seed weight and single plant yield. In M1 generation the results disclosed that there was more reduction at higher doses compared to lower doses for all the characters.

A study on the adoption of the recommended package of practices in bt cotton by the farmers of Ranga Reddy District of Andhra Pradesh

A study was taken up with the main objective of identifying and analyzing the adoption of package of practices by the Bt cotton farmers as recommended by the scientists of ANGRAU. It was conducted in 2013 with a sample of Fifty (50) farmers in the Ranga Reddy district of Andhra Pradesh. Cent per cent of the respondents fell in the category of fully adopted with respect to seed treatment. 96.00 per cent of the respondents fully adopted recommended time of sowing, pest management practices & time of harvest; while the remaining 4.00 per cent fell in the category of partially adopted.

Nuclear pollution: Forthcoming unsolvable global problem

After Second World War, the nuclear knowledge that was under military control had led to the production of atomic weapons was redeployed for peaceful purposes in many countries. Atomic energy counted several benefits and realized that this energy source was not risk-free. There was the danger of nuclear war, the spread of atomic weapons, and nuclear terrorism. But intensive international cooperation and a number of negotiated agreements suggested that these dangers could be avoided.

Characterization of slow release of sulphur nutrient – a zeolite based nano-fertilizer

An attempt was made to synthesis a Nano-zeolite based slow release sulphur nutrients and to characterize them using high resolution instruments as a confirmation note of the effort. Zeolite is a natural super porous mineral (part of group of hydrated alumino silicates) carrying a negative charge balanced by freely moving cations with positive charges. This provides an ideal trap for positive cations which are then released that commensurate with crop nutrient requirement. Naturally occurring mesoporous material (zeolite) was reduced to a desirable nanosize (50-60nm).

Sorption characteristics of nano zeolite based slow release sulphur fertilizer

Understanding the sorption process in natural zeolites is necessary for effective utilization of these minerals as nutrient adsorbents and consequently as controlled releases of plant nutrients. This research was undertaken to characterize the ability of natural zeolites minerals to adsorb and release sulphur. The potential for sorption of these ions were evaluated by applying the Langmuir equations. Thus a percolation reactor experimental setup was used to study the sorption, desorption pattern of nutrients. The nano-zeolite has been fortified with a sulphur source (Gypsum).

Antimicrobial investigation of different medications against nosocomial infections causing Staphylococcus aureus

Since it was first described in the 1990s, Methicillin-Resistant Staphylococcus aureus infection among people with no contact with a hospital setting or with no traditional risk factors has spread worldwide and is now an important epidemiological and public health problem. This study aims to emphasize the current importance of this emergent pathogen in our area. In the present study we have analyzed the impact of modified MRSA screening of carriers and patients on epidemiological situation of MRSA during 2010-2013 in Gwalior region of Central India. All S.

Effect of nanoparticles on the antibacterial activity of antibiotics

In this work, CdS nanoparticles were synthesized via chemical method and its activity on microorganism pathogens was investigated. X- ray Diffraction (XRD), Atomic Force Microscopy (AFM) and UV-VIS transmission spectroscopic analysis were utilized to characterize the crystalline structure, size, transmission spectra of nanoparticles. Diffraction analysis confirms the formation of cubiform and hexangular structures of nanoparticle, The AFM show the formation of combination of nanoparticle with particle size travel 7 – 20 (nm).

Preliminary antibacterial screening of a traditional medicinal formulation used as medicine in Sokoto, Nigeria

The antibacterial activity of a traditional medicinal formulation also called “komi da ruwanka” used in the treatment of diseases was carried out using the agar well diffusion. The formulations sampled from three different locations exhibited a significant (P<0.05) antibacterial activity against Staphylococcus aureus: (SOK115.67 ± 0.67, SOK2 15.00 ± 0.58 and SOK315.00 ± 0.58) while there was no significant (P>0.05) antibacterial activity on the other isolates used (Bacillus subtilis, Escherichia coli, Salmonella typhi and Shigella flexnerii).

Marine pollution and its effect to the bio-diversity

Coastal and estuarine ecosystems have been, and still are, heavily influenced by the human species through pollution and habitat loss throughout the world. This coastal pollution and its impacts have resulted in a number of environmental issues including the enrichment of enclosed waters with organic matter leading to eutrophication, pollution by chemicals such as oil, and sedimentation due to land-based activities. Over Eighty per cent of all marine pollution originates from land-based sources which are primarily industrial, agricultural and urban.

Early larval stages of the spiny lobsters, Panulirus homarus, Panulirus versicolor and Panulirus ornatus cultured under laboratory conditions

Early developmental stages of the phyllosoma larvae of three tropical spiny lobsters, Panulirus homarus, Panulirus versicolor, and Panulirus ornatus have been described by rearing them. P. homarus phyllosoma grew to the V stage in 46-61 days. P. ornatus larva reached the IV stage in 32-36 days, while P. versicolor attained the same stage in 30-38 days. More than one or two moults were recorded between different stages, such as after II stage, in all the three lobsters. Early stages of phyllosoma larvae of P. homarus could be successfully reared in low salinity of 28 psu.
