Beneficiation studies on beach placer sample for steel making industries
Beneficiation studies were carried out on the Talashil beach placer sample of South Maharastra Coast, India. The sample contains magnetite, ilmenite, rutile, hematite, goethite and chromite as opaque minerals in the sample. The total heavy minerals fraction reaches 53.8 % by weight whereas the total magnetic minerals are 56.9%. It is observed that the 2nd stage DHIMS magnetic fraction contains 65.2 % Fe2O3 with an over all yield of 37.8 % and a 86 % recovery from a containing 26.8 % Fe2O3 feed. This product can be used in the pellet feed for steel making after suitable blending with high-grade iron ore fines
Development and Diffusion of Sorghum Improved Cultivars in India: Impact on Growth and Variability in Yield
Sorghum is the third cereal crop after rice and wheat in India, mostly grown
under marginal and stress-prone areas of Semi-Arid Tropics (SAT). NARS,
ICRISAT and private seed companies are the major stakeholders working for
sorghum crop improvement in the last five decades (1960-2012). Altogether
more than 256 improved cultivars have been notified and made available to
farmers during the same time. The current knowledge about spread and impact
of sorghum improved crop varieties in the country is incomplete. The present
study made an attempt to address these issues with help of primary as well as
secondary sources of information. The analysis has concluded that nearly 80
per cent of total sorghum area is under improved cultivars which helped to
increase the country productivity levels by 85 per cent during 1960 and 2010.
This aptly proves that role of sorghum improved cultivars in sustaining the
higher yields
Synthesis, Spectroscopic Characterisation, and Biopotential and DNA Cleavage Applications of Mixed Ligand 4-N,N-Dimethylaminopyridine Metal Complexes
The mixed ligand transition metal complexes of 4-N,N-dimethylaminopyridine (DP) and chloride as primary and secondary ligands with the general formula [M(DP)3Cl3]; M = Cr(III) and Fe(III); [M′(DP)4Cl2]M′ = Co(II), Ni(II), Cu(II), and Cd(II) were synthesized in a microwave oven. The complexes were characterized by FT-IR and UV, 1HNMR, 13CNMR spectra, TG/DTG, and various physicoanalytical techniques. From the magnetic moment measurements and the electronic spectral data, a distorted octahedral geometry was proposed for the complexes. The complexes express similar trend of thermal behaviour such that they lose water of hydration initially with the subsequent emission of organic and inorganic fragments and leave left the metal oxides as residue. The activation thermodynamic parameters, such as , , , and of the metal complexes, illustrate the spontaneous formation of the complexes. The antimicrobial studies against various pathogenic bacterial and fungal serums insist on that the enhanced potential of the complexes over their ligand and their biopotential properties increases with concentration. The DNA interaction of the synthesized complexes on CT-DNA was investigated by UV-Vis spectroscopy, viscosity, thermal denaturation, and electroanalytical experiments and their binding constants () were also calculated
Prediction of outcome in adults with severe falciparum malaria: a new scoring system
BACKGROUND: Mortality of falciparum malaria is related to the presence of severe complications. However, no scoring system is available to predict outcome of these patients. The aim of this paper was to devise a simple and reliable malaria prognosis score (MPS) to predict the outcome of adults with severe malaria. METHODS: All slide-positive severe falciparum malaria patients admitted to Ispat General Hospital were studied. Eight clinical parameters that may potentially differentiate or influence the outcome were identified to predict recovery or death RESULTS: Of 248 severe malaria cases, 35 died. There were 212 adults (34 deaths) and 36 children (one death). The malaria score for adults was (MSA) = 1(severe anaemia) + 2 (acute renal failure) + 3(Respiratory distress) +4 (cerebral malaria). The MSA ranges from 0 to 10. The mortality was 2% for MSA 0 – 2; 10% for MSA 3–4, 40% for MSA 5–6 and 90% for MSA 7 or more. The sensitivity is 89.9% and positive predictive value is 94.1% when 5 is taken as the cut off value. CONCLUSION: MSA is a simple and sensitive predictor. It can be administered rapidly and repeatedly to prognosticate the outcome of severe malaria in adults. It can help the treating doctor to assess the patient as well as to communicate to the relatives of the patients about prognosis. The score needs revalidation in other geographical areas
Development and Diffusion of Sorghum Improved Cultivars In India: Impact on Growth and Stability in Yield
Sorghum [Sorghum bicolor (L.) Moench] is one of the major staple foods for the poorest and most food-insecure people across the semi-arid tropics of the world. Sorghum bicolor ssp. Verticilliflorum is believed to be the progenitor of cultivated sorghum (Harlan, 1972). It is cultivated in wide geographic areas in Africa, Asia, Americas and the Pacific regions. While it is the fifth most important cereal crop in the world after wheat, maize, rice and barley, in India, sorghum is the fourth largest cereal crop after rice, wheat and pearl millet and the second major food crop in Africa after maize. Sorghum is often a recommended option for farmers operating in harsh environments where other crops do poorly, as it can be grown with limited rainfall (400-500 mm) and often without or with limited application of fertilizers and other inputs. In India, sorghum is grown in both rainy (2.6 million ha) and postrainy (3.5 million ha) seasons. An estimated 2 million ha is under forage sorghum, grown in the summer season. Nearly 30-40% of the rainy season sorghum is grown as the sole crop while the rest is cultivated as an intercrop with pulses and oilseeds in India. On the other hand, 90% of postrainy season sorghum is grown as a sole crop, which is most preferred for food purposes
Pigeonpea Baseline and Early Adoption Surveys in South Asia, Insights from TL-II (Phase 1) Project in India.
Pigeonpea is an important pulse crop particularly in the semi-arid tropics of India contributing towards the
nutritional security and also generates significant income to small and marginal farmers. Its share in India’s
pulse production is around 16%. India is the largest pigeonpea producing country in the world accounting for
nearly 67% of the total production. Being a major pigeonpea consumer in the world, India imports around
0.6 million tons of pigeonpea per year to meet the domestic needs from Africa, Nepal and Myanmar. Area
and production of pigeonpea in India showed a steady growth until recently. However, the productivity
in the country has stagnated between 700 and 800 kg ha-1. Recent initiatives like National Food Security
Mission (NFSM), Accelerated Pulse Production Programme (A3P) and enhancement of minimum support
price created more interest in pigeonpea growers in the country. Pigeonpea is one of the mandate crops of
the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and this premier international
institute has been contributing significantly to the genetic improvement and crop management in India
and Africa during the last four decades. The generous support received from the Bill and Melinda Gates
Foundation (BMGF) has provided ICRISAT an opportunity to work more intensively with its research and
development partners to demonstrate the potential of new technologies to enhance the yields, raise the
profitability and revive the interest of the farmers in pigeonpea crop in India and the strategy chosen is
farmer participatory varietal selection (FPVS). This report synthesizes the efforts made under the Tropical
Legumes-II Project during the short period of three years (2007-10) in the states of Andhra Pradesh and
Maharashtra for pigeonpea crop improvement in India. Overall, the FPVS results established that the new
improved varieties outyielded the respective check varieties in the two states. The diffusion and adoption
of these varieties increased significantly in the targeted districts. From the past lessons learnt, the report
re-focuses on further efforts needed during the second phase of the project to achieve greater success and impact
Properties of Fuzzy Labeling Graph
Abstract In this paper a new concept of fuzzy labeling is introduced. A graph is said to be a fuzzy labeling graph if it has fuzzy labeling. Fuzzy sub graph, union, fuzzy bridges, fuzzy end nodes, fuzzy cut nodes and weakest arc of fuzzy labeling graphs have been discussed. And number of weakest arc, fuzzy bridge, cut node and end node of a fuzzy labeling cycle has been found. It is proved that ∆ (G ω ) is a fuzzy cut node and δ(G ω ) is a fuzzy end node of fuzzy labeling graph. Also it is proved that If G ω is a connected fuzzy labeling graph then there exists a strong path between any pair of nodes. Mathematics Subject Classification: 03E72, 05C72, 05C7
