Effect of Polyethylene Glycol Induced Water Stress on Physiological and Biochemical Responses in Pigeonpea (Cajanus cajan L. Millsp.)

Water deficit induced by Polyethylene glycol (PEG) affect physiological and biochemical changes in pigeonpea. The plants were subjected to two progressive stresses: moderate (-0.51 MPa) and severe (-1.22 MPa) respectively. The water stress condition was created by irrigating 14 days old grown seedling pot with PEG nutrient solution and decreasing the osmotic potential -0.04 MPa regularly. Relative water content (RWC) content was significantly reduced under water stress condition. Increase in the free proline content during water stress condition suggests that proline is one of the common compatible osmolytes under water stress condition. The genotype exhibited lower accumulation of catalase (CAT) and increased activity of superoxide dismutase (SOD) and Peroxidase (POD) under stressed condition. The present data suggest a relation between proline content and water stress and a well developed antioxidant defense mechanism activated during water stress

Synthesis, Spectral and Antimicrobial Studies of Lanthanide (III) Nitrate Complexes with Terdentate ONO Donor Hydrazones

Few lanthanide (III) nitrate complexes with hydrazones obtained by the condensation of 3-[m/p (hydrazino carbonyl)] phenyl sydnone and hydroxy aryl aldehyde or ketones have been synthesized and characterized by elemental analysis, molar conductance measurements, magnetic moments, Infrared, electronic and 1HNMR spectral studies. The spectral studies show that the hydrazones reacts in enol form and as dibasic terdentate ONO donor nature. From the results the coordination number eight for lanthanide ion in the complexes is proposed. The thermal behaviour, stability ranges, percentage of weight loss, percentage of residue obtained after decomposition of Ln (III) nitrate complexes has been studied. Further more the antimicrobial activity of the ligand and its complexes as inhibiting agents has been screened in vitro against two kinds of pathogenic bacteria Salmonella paratyphi, Bacillus cirroflagellosus and pathogenic fungi Aspergillus niger, Candida albicans

Valuation and Return Dynamics of New Ventures.

We develop and analyze a model of a multi-stage investment project that captures many features of R&D; ventures and start-up companies. An important feature these problems share is that the firm learns about the potential profitability of the project throughout its life, but that "technical uncertainty" about the research and development effort itself is only resolved through additional investment by the firm. In addition, the risks associated with the ultimate cash flows the firm realizes on completion of the project have a systematic component, while the purely technical risks are idiosyncratic. Our model captures these different sources of risk, and allows us to study their interaction in determining the risk premia earned by the venture during development. Our results show that the systematic risk, and the required risk premium, of the venture are highest early in its life, and decrease as it approaches completion, despite the idiosyncratic nature of the technical risk.

Effect of ultra dry seed storage on longevity of onion (Allium cepa) and chinaaster (Callistephus chinensis) under ambient and controlled temperatures.

Not AvailableUltra dry seed storage was studied in onion (Allium cepa L.) and china aster [Callistephus chinensis (L.) Nees] to find out its effect on seed longevity under ambient and controlled low temperatures. Seeds of onion cultivars Arka Kalyan and Arka Niketan ultra dried to 2.8 and 2.6 %, respectively, and seeds of china aster cultivar Arka Kamini ultra dried to 3.0% were compared with seeds of respective cultivars having moisture content close to recommended levels for packing in moisture proof containers. These seeds were hermetically sealed in aluminium pouches and stored at ambient and controlled (constant 15°C) temperatures. The initial germination in onion was 90.0 and 88 % in Arka Niketan and Arka Kalyan, respectively, and it remained unaffected after ultra drying. During storage, ultra dry seeds and seeds with ~5% moisture content of both varieties showed no significant reduction in seed germination, first count, seedling vigour and field emergence even after 54 months of storage both under ambient and controlled temperatures. In china aster, seeds with 5.9% moisture showed decline in seed viability and vigour under ambient temperature after 18 months of storage and rapid decline was noticed after 24 months of storage, reaching zero at 36 months but at 15°C showed no decline in viability up to 48 months of storage. Ultra dry seeds maintained higher viability and vigour at both ambient and at 15°C even after 48 months of storage. Genetic fidelity tests on onion seed clearly demonstrated that neither the profiles of soluble proteins and enzymes nor the DNA were affected by ultra drying.Institute fun

Not AvailableRole of fruit maturity, postharvest ripening and seed extraction techniques on seed quality of papaya (Carica papaya L.) cv. Surya was studied. The seeds extracted from ¾th ripe fruits onwards showed significantly higher 100 seed weight, germination and vigour compared to the seeds from early harvested fruits. However, half ripe fruits showed good germination and vigour when they were kept for postharvest ripening for 6 days. The best stage of fruit harvest for obtaining best quality seed was when the ¾th of the fruit skin turned yellow. The seeds from these fruits not only gave better germination and vigour but also showed better storability compared to the seeds extracted from the fruits of early harvested. Fermentation for 24-48 hr was found ideal for easy removal of sarcotesta, the mucilage surrounding the seed surface, without affecting the quality of the seed.Not Availabl

A grounded theory study of the narrative behind Indian physiotherapists global migration

It is estimated that an additional 6.4 million allied health professionals are required to address India's health challenges. Physiotherapy is amongst the largest of these professions. Over the last decade, thousands of Indian physiotherapists have sought to study and work overseas. In this study, 19 physiotherapists from across India were interviewed. Data were collected and analysed using construct+ivist grounded theory methods. The findings indicate that the Indian physiotherapy profession faces many political and clinical hierarchical challenges within the Indian healthcare infrastructure. The profession's education provision has developed, and the private clinical sector has grown, but there are significant disparities in quality and standards across the sector. The profession in India has variable autonomy, is not nationally regulated, is poorly paid, and the leadership has been divided. The political, educational, and clinical context in Indian physiotherapy impacts upon physiotherapists' ability to practise effectively to their professional satisfaction. Individual physiotherapists are frustrated by their workplace and travel overseas where they hear that the physiotherapy profession and practice is different. Whilst the disjunctures influencing these factors continue, and overseas physiotherapy practice is perceived as different and superior, Indian physiotherapists will continue to seek to migrate overseas, and facilitating their return will be challenging

Not AvailableThe potential health benefits of sprouted grains are well known; Sprouted grains are good sources of chlorophyll and contain grass juice factor that improves the performance of the livestock (Sneath and Mclntosh 2003, Shipard 2005).Feeding of quality green fodder to dairy animals is highly essential to maintain the productivity, fertility and economical viability of the farm. The major factors responsible for the unavailability of green fodder are scarcity of land due to small land holding size, shortage of water or saline water and labour (Naik et al. 2013). In this scenario, supplementation of sprouted grains in the ration of dairy animals is coming up as a viable alternate technology to conventional green fodder for the livestock farmers (Naik et al. 2015). However, only a few reports are available on the feeding value of the sprouted maize grains to the dairy animals in India (Naik et al. 2012, 2014).Therefore, an experiment was conducted to find out the effect of feeding sprouted maize grains on digestibility of nutrients in heifers.Not Availabl
