    The seismic and wind load acting on the 2-storeyed building of dimension 120 ft x 98 ft located in Oxford, MS, were calculated and the seismic load was considered for the design of the 120 ft long and 24 ft high load-bearing wall because it being critical. The maximum loading was computed using different load combinations. The masonry behavior and masonry specifications were considered to select the masonry unit, grout, and mortar for the load-bearing wall. The seismic design requirement for the shear and slender wall was fulfilled for the special reinforced masonry wall. The in-plane and out-of-plane loading scenarios were considered for finding the required reinforcement in the wall to resist the bending moment and the shear. The special reinforced masonry wall was designed using the Strength Design method. The cost of construction of a 24 ft high wall with reinforced concrete and the reinforced masonry was computed. It was found that the construction with reinforced masonry came out much cheaper as compared to the construction with reinforced concrete

    The measurement of indoor radon, thoron and their daughter products was carried out in about fifty houses of dist. Shahjahanpur and Hardoi of Central Uttar Pradesh, India using LR-115 plastic track detectors. The measurements were made in residential houses from June 2008 to May 2009 hanging   twin cup radon dosimeter at a height of 1.5-2m from ground level. The twin cup radon dosimeter can record the values of radon, thoron and their decay products separately. The graphs were plotted for radon concentration versus number of houses, thoron concentration versus number of houses and dose rate versus number of houses for different seasons. The resulting dose rates due to radon, thoron varied from 0.04 to 1.46 µSv/h.  The observed radon and thoron concentration inside the houses of central Uttar Pradesh were found to be lower than the ICRP recommended value of 200 Bqm-3 and thus are within safe limits

    Get PDF
    The most important way to increase the grain yield of food legumes per unit area under stress environment should be consist of proper technological backup with infrastructure, timely availability of quality inputs along with policy support. Efficient water management is one of the critical inputs as in general perception is that legumes need no supplementary water, whereas research finding revealed that need based watering at critical stages are capable to improved production by 15-25 % depending up how much stress has already being faced by the standing crop till now

    Age Sequence in Small Clusters Associated with Bright-Rimmed Clouds

    Get PDF
    Bright-rimmed clouds (BRCs) found in H II regions are probable sites of triggered star formation due to compression by ionization/shock fronts, and it is hypothesized that star formation proceeds from the exciting star(s) side outward of the HII region ("small-scale sequential star formation"). In order to quantitatively testify this hypothesis we undertook BVIc photometry of four BRC aggregates. The amounts of interstellar extinction and reddening for each star have been estimated by using the JHKs photometry. Then we constructed reddening-corrected V/V-Ic color-magnitude diagrams, where the age of each star has been derived. All the stars turned out to be a few tenths to a few Myr old. Although the scatters are large and the numbers of the sample stars are small, we found a clear trend that the stars inside or in the immediate vicinity of the bright rim are younger than those outside it in all the four aggregates, confirming the hypothesis in question.Comment: 10 pages, 2 figures; accepted for publication in PAS

    Comparative Study of Colour Doppler versus Non Stress Test as a predictor of Perinatal outcome in PIH and IUGR

    Background: Hypertensive disorders and intrauterine growth restriction are common complications encountered during pregnancy. This study was conducted to observe the usefulness of systolic/ diastolic (S/D) ratio in umbilical artery as compared with non-stress test (NST) to predict perinatal outcome in pregnancies complicated with hypertensive disorders and intrauterine growth restriction (IUGR). Methods: It was a prospective observational which was conducted on patients undergoing antenatal visits at the department of obstetrics and gynaecology, Army hospital research and referral, New Delhi from May 2017 to April 2019. NST was started at 32 weeks twice weekly in all patients. All patients were subjected to umbilical artery Doppler velocimetry waveform on weekly basis or every third day in cases of nonreactive NST. Results: Out of 140 patients, 53 patients (37.9%) had PIH and 44 (31.4%) had IUGR. 43 cases (30.7%) had both PIH and IUGR. Among the 140 patients, 40 patients (28.6%) had non-reactive NST and 60 patients (42.9%) of the patients had abnormal doppler. Abnormal doppler and non-reactive NST were associated with APGAR score of less than 7 at 5 minutes in the newborn. Abnormal perinatal outcome was more in abnormal doppler than normal doppler and the finding was statistically significant (p<0.05). Conclusions: Overall sensitivity and diagnostic accuracy of Doppler is better as compared to that of NST in terms of detecting adverse perinatal outcomes

    FORMULATION AND EVALUATION OF TASTE MASKED ORAL DISPERSIBLETABLET OF CIPROFLOXACIN WITH ION EXCHANGE RESIN

    Get PDF
    Bitter taste is one of the important formulation problems that are encountered with many drugs, like Ciprofloxacin. In modern times, the most improved & easy technique is to formulate tasteless complexes of ciprofloxacin with ion exchange resin (Indion 234). After acid activation and swelling in water, resin & ciprofloxacin (proper ratio) was stirred for definite time & unbound drug in filtrate was estimated spectrophotometrically and drug-loading efficiency was calculated. The molecular properties of drug complexes by FT-IR study confirm the complexation of ciprofloxacin with Indion 234. The influence of superdisintegrants, crospovidone and sodium starch glycolate on disintegration time, wetting time and water absorption ratio was studied

    Chandrayaan-3 Alternate Landing Site: Pre-Landing Characterisation

    Full text link
    India's third Moon mission Chandrayaan 3 will deploy a lander and a rover at a high latitude location of the Moon enabling us to carry out first ever in-situ science investigations of such a pristine location that will potentially improve our understanding on primary crust formation and subsequent modification processes. The primary landing site (PLS), is situated at 69.367621 degS, 32.348126 degE. As a contingency, an alternate landing site (ALS) was also selected at nearly the same latitude but nearly 450 km west to PLS. In this work, a detailed study of the geomorphology, composition, and temperature characteristics of ALS has been carried out using the best-ever high resolution Chandrayaan 2 OHRC DEMs and Ortho images, datasets obtained from Chandrayaan 1 and on-going Lunar Reconnaissance Orbiter. For understanding the thermophysical behaviour, we used a well-established thermophysical model. We found that the Chandrayaan 3 ALS is characterised by a smooth topography with an elevated central part. The ALS is a scientifically interesting site with a high possibility of sampling ejecta materials from Tycho and Moretus. Based on the spectral and elemental analysis of the site, Fe is found to be near approx. 4.8 wt.%, with Mg approx. 5 wt.%, and Ca approx. 11 wt.%. Compositionally, ALS is similar to PLS with a highland soil composition. Spatial and diurnal variability of around 40 K and 175 K has been observed in the surface temperatures at ALS. Although belonging to similar location like PLS, ALS showed reduced daytime temperatures and enhanced night-time temperatures compared to PLS, indicating a terrain of distinctive thermophysical characteristics. Like PLS, ALS is also seems to be an interesting site for science investigations and Chandrayaan 3 is expected to provide new insights into the understanding of lunar science even if it happens to land in the alternate landing site.Comment: 13 pages, 7 figure

    Improvement of faba bean (Vicia faba L.) yield and quality through biotechnological approach: A review

    Get PDF
    Faba bean (Vicia faba L.), an old-world grain legume, is grown approximately in 3 m/ha area world-wide from temperate, tropical to hot arid conditions. It is such a wonderful legume that it can excel even under adverse soil conditions; acidic or saline alkaline (pH 4.5 to 9.0). In favourable conditions, it gives very high yields, but low yield may result from biotic and abiotic stress. In India, it is still treated as minor legume. Genetic transformation based on Agrobacteria is possible. Several random amplified polymorphic DNA (RAPD) markers linked to a gene determining hypersensitive resistance to race 1 of the rust (Uromyces viciae-fabae) have been reported. Molecular breeding for resistance to broomrape, Ascochyta blight, rust, and chocolate spot have been obtained. The use of marker assisted selection (MAS) can complement conventional breeding by speeding up the selection of desirable traits and increasing selection efficiency. Recently, markers linked to a gene controlling growth habit or to select against traits affecting the nutritional value of seeds have also been reported. Lack of suitable cultivar can be easily overcome by application of modern tools and techniques. Several in-vitro techniques would be very useful for faba bean breeding. New techniques such as protoplast fusion, regeneration, and embryo-rescue assisted interspecific crossing could probably be introduced to V. faba L. to improve yield and quality. This review work examines the role of various techniques with reference to faba bean improvement.Key words: Vicia faba, faba bean, grain quality, resistance breeding, nitrogen fixation, zero tannin
