Retrofitting of a 420 kV draw-lead type bushing with a draw-rod type – Part I

On observation of deterioration of tan-δ value to 1.08 %, i.e., surpassing the limiting value of 0.7 % as defined in IEC60137 for the 420 kV OIP bushing for a 315 MVA, 400 / 220 / 33 kV transformer located at substation Katni (India), a decision was made to replace the bushing. The replacement was risky, and it was a threat of causing the catastrophic failure for the transformer itself and the colossal loss to the neighbouring equipment and structures

Not AvailableA study was undertaken to evaluate the nutritionalresponse of organically grown diets in buffaloes on nutrientsutilization and nutrient efficiency for milk production. Forthis, ten milch Murrah buffaloes of average body weight(490.72±6.65 kg), milk yield (8.13± 0.33 kg), and lactationstage (85±5.28 days) were distributed in inorganic (InDg)andorganic dietary groups (OrDg) with five animals in each.Buffaloes of InDg and OgDg were fed sorghum hay–berseemfodder-concentrate mixture-based diets grown inorganicallyand organically, respectively. After 60 days of feeding, adigestion cum metabolism trial was conducted to assess feedintake, nutrient utilization, and N balance, while milk yieldand composition were recorded fortnightly. DM, CP, digest-ible crude protein (DCP), and metabolizable energy (ME)intake (g/Kg w0.75) were similar in animals of InDg andOrDg. NDF, ADF, and hemicellulose digestibility were (P<0.05) higher in animals on OrDg (59.20, 51.55, and 62.67)than InDg diet (54.57, 43.72, and 56.61 %), respectively.Urinary n loss (g/day) was (P<0.05) lower in OrDg (67.23)than in InDg (83.55); however, milk N was comparable inanimals of both dietary groups (47.36 vs 45.82 g/day). Nitro-gen balance was higher in animals of OrDg (39.72) than inInDg (28.08). DCP, TDN, and ME values of both diets weresimilar. No effect of diet was observed on milk yield and itscomposition; however, increased lactation length decreasedmilk yield. Buffaloes on both diets had similar efficiency anconversion ratio of nutrients for milk production. Resultsrevealed that diets (organically vs. inorganically grown) haveno effect on milk yield and its composition; however, buffa-loes on organic diet have higher fiber digestibility and lowurinary N loss which did not affect the dietary nutrientsefficiency and conversion ratio for milk productionNot Availabl

Not AvailableRainfed arable systems of India accounts about 55% of the total sown area (Shankar, 2011), while slightly higher parts of the it about 62% is rainfed in Madhya Pradesh state of India. The Madhya Pradesh state has 14.9 M ha cultivated area constitutes almost half of the total geographical area and agriculture is the major source of livelihood for more than 70% human population, production systems should be resilient to risks, be able to ensure food, nutritional security and strengthened livelihood systems with minimum environmental externalities. The Chambal division is consisting of Morena, Sheopur and Bhind district of Madhya Pradesh. Total geographical area (TGA) of Chambal division is 16.054 lakh ha, net crop sown area 7.52 lakh ha and area under ravines is 3.11 lakh ha, which is highly degraded land (Singh et al., 2018). Out of total area under ravines in Chambal division have 1.92 lakh ha in undivided Morena (Morena and Sheopur) district (Tomar et al., 2015). Ravines owe their origin to rill-erosion on highly erodible soils by run-off rain water. Ravines mean not only a loss of nonrenewable land-resource but also destruction of rural economy, loss of public property, creation of socioeconomic problems such as dacoitinfestation and unemployment (Singh et al., 2014). Since formation of ravines was a function of uncontrolled run-off, the management of rainwater through storage of rain water in ponds watershed basis was an appropriate approach for control of ravine and increase of irrigated areas (Verma and Singh, 2009). The groundwater table of the area is approximately 122 feet deep. The over exploitation of underground water through well and tube wells in the district the water table goes downwards to 2 to 5 feet every year and ordinary wells and open well become dry and pose problems of domestic use, animal rearing and agriculture activities in remote areas. In general, the quality of under ground water also deteriorated (salinity and alkalinity) with decreasing of water table in some patches are also seen. Rain water collection in ponds and its recycling is very important component of rainfed as well as in irrigated agriculture system. Runoff collection can be done in several ways depending upon the characteristics and suitability site. Runoff will get stored temporarily against submersible check dams, pond, stop dam, anicut, the construction of which will be very essential for stabilization of gully-bed, etc. Also, selection of suitable sites for construction of farm ponds or tanks is necessary to store runoff. Hon'ble Prime Minister of the country has urged upon doubling farmers' income by 2022. Therefore, it is essential that farm productivity should increase in irrigated as well as rainfed areas. In Morena district the pearlmillet, pigeonpea, soybean, blackgram, wheat, mustard, chickpea and vegetables are major existing crops but the productivity of these crops is low from potential yield of crops owing to adoption of local varieties, non-adoption of improved agronomic package, mono-cropping, intensive and repeat tillage, faulty crop establishment method, undulating topography, burning of crop residues and several abiotic and biotic climatic abnormalities.Not Availabl

Not AvailableCarbosulfan insecticide is widely used in agriculture and was recently proposed for treatment against pyrethroid-resistant mosquitoes. The mutagenic and genotoxic effect of carbosulfan was carried out in fish Channa punctatus using micronucleus (MN) test and comet assay. The 96 h LC50, estimated by probit analysis in a semi-static bioassay experiment, was 0.268 mg l1 Based on the LC50 value, three sub-lethal concentrations of carbosulfan (1/4th LC50 = 67 lg l1 1/2nd LC50 = 134 lg l1 and 3/4thLC50 = 201 lg l1 ) were selected and fishes were exposed to the said concentrations for 96 h and the samplings were done at regular intervals of 24 h for assessment of the MN frequencies and DNA damage. In general, significant effects (P < 0.01) from both concentrations and time of exposure were observed in exposed fishes. The MN induction was highest on 96 h at all the concentrations in the peripheral blood. Similar trend was observed for the DNA damage measured in terms of the percentage of tail DNA in the erythrocyte and gill cells. This study confirmed that the comet and micronucleus assays are useful tools in determining potential genotoxicity of water pollutants and might be appropriate as a part of monitoring program.Academy of Science for Developing World (TWAS)Department of Biotechnology, Government of India (DBT

Rare initial presentation of ALL as pleural effusion

Leukemias rarely present as pleural effusion as the first manifestation of the disease process. Most commonly this complication is seen in solid tumors such as the lung, lymphomas, carcinomas of the breast and gastrointestinal tract. A case of 40 year old male is hereby highlighted who presented with a massive pleural effusion as the initial presentation of his disease process (ALL) which is a rare phenomenon to be seen

Not AvailableIn the present study an estimation of livestock enteric CH4 emission has been made from feeding systems (diets) for different animal functions (maintenance, production and growth) prevailing in different agroecological regions (AERs) of India using livestock population 2003. Estimations comprised of dietary intake, digestibility and CH4 emission factors for ruminant species of different age groups determined from feeding systems/diets. Methane production (ml g–1) from production diets in animal species tended to be more than growth and maintenance diets. Methane production (g kg digestible dry matter (DDM–1)) and percentage energy loss as CH4 varied significantly amongst diets, animal species and AER. Indian livestock emitted 9.10 T CH4 from enteric fermentation. Contribution of female animal stock was more than males, except indigenous cattle, where males contributed more (53.60%) than females (46.40%). Wide variability recorded in the study for intake, digestibility, CH4 production and CH4 emission factors in the animal species for prevailing feeding systems/diets presents ample scope to abate the livestock resource CH4 production through appropriate nutritional interventions.Not Availabl
