Abstract

An experiment was conducted in R.B.D. with seven treatments in four replications with olitorius jute variety JRO524 for five consecutive years (2002-07) at the experimental farm of the Crop Research Station, Bahraich in a plot size of 3X5 m² with a row spacing of 30 cm. Recommended doses of N:P:K @ 60:30:30 kg ha^-1 were applied. The treatment with soil application of Trichoderma viride thrice, i.e., 7, 15, 30 DAS was found best in controlling seedling blight, collor rot, stem rot and ischolar_main rot diseases giving minimum per cent disease incidence (1.45, 3.07, 4.70 and 4.92, respectively) as compared to control (16.12, 9.47, 16.67 and 16.34, respectively). Soil application with T. viride twice (7 and 15 DAS) showed 2.05, 4.42, 6.14 and 6.15% incidence of the same diseases and ranked second. The treatment with carbendazim 50WP @ 2g kg⁻¹, seed showed 8.52% seedling blight 5.24% collor rot, 6.93% stem rot and 8.56% ischolar_main rot incidence. Mean dry fibre yield was highest (25.70q ha⁻¹) in the plots when the soil was treated with T. viride at 7, 15 and 30 DAS, while it was lowest in control (17.76q ha⁻¹) and in carbendazim treatment it was 22.23q ha⁻¹. Variation in yield was due to the variations in plant height and basal diameter.

Abstract

Introduction: Acute poisoning is one of the commonest pediatric emergencies and an important cause of mortality. Objectives: To study the magnitude and demographic profile of acute poisoning among hospitalized children (1Month-18 years of age) in Jammu, India.

Materials & method: All the children between one month and eighteen years of age, admitted to Pediatric wards of SMGS Hospital, Government Medical College, Jammu, India, over a period of one year as a case of acute poisoning were included in the study. The information obtained from Subjects / Parents / Guardians and examination of subjects was recorded on a pretested proforma and analyzed.

Results: A total of 245 (1.76% of total admissions) children were admitted with acute poisoning during the study period. Male - Female ratio was1.58:1. Majority 243(99.18%) patients were of oral poisoning and maximum were in the age group of more than one to five years (71.42%). Majority 219(89.39%) patients of acute poisoning were accidental. Suicidal attempts constituted 2.45% and 1.22% cases were of homicidal nature. Majority (41.63%) of poisoning cases were due to accidental ingestion of household products followed by drugs ingestion (23.67%), food poisoning (16.33%) and agricultural/industrial products ingestion (9.8% cases). Maximum 187(76.33%) patients of acute poisoning recovered whereas 3 patients (1.22%) died.

Conclusion: Acute poisoning in children is usually accidental with favorable outcome. Deaths do occur depending upon the nature of poisoning and the stage at which patient seeks medical care. Poisoning can be prevented by increasing public awareness, counseling and correct guidance to the parents.

Abstract

The Jabalpur earthquake of magnitude 5.8 occurred on May 22, 1997 along seismically active Narmada-Son Lineament (NSL) in central India, with its epicenter about 30 km southeast of Jabalpur. A maximum intensity I_o = VIII on MM scale was observed in Jabalpur and surrounding region. The isoseismal map prepared for this earthquake shows NE-SW trend which in general agrees with the focal mechanism solution indicating thrust faulting along a ENE-WSW fault with minor strike-slip component. Several ground cracks mapped in meizoseismal area show a dominant N75° E trend. The damage pattern of the constructions clearly shows a strong correlation with lithology, structures and soil cover of the area. There are no foreshocks reported for this earthquake and only a few aftershocks are recorded. which warrant a close monitoring of this region.

Abstract

Primordial dwarfism is a rare anomaly with over 200 sub-types, which results in a relatively small body size in all stages of life, beginning at the intrauterine period. The life expectancy for these patients is around 30 years but very few survive their intra-uterine phase. Other features associated with primary dwarfism reported till date includes pigmentation of skin, cleft lip and palate, and semilobar holoprosencephaly. We report an unusual combination of primordial dwarfism associated with isolated cleft palate.

Abstract

Pregnane and Xenobiotic Receptor (PXR) is a member of the nuclear receptor super-family of ligand-regulated transcription factors. Some of its key roles in normal physiological controls and patho-physiological situations are recently becoming more apparent. PXR responds to a large range of chemically distinct endobiotics (steroids, bile acids and their derivatives, vitamins, etc.) and xenobiotics (synthetic drugs, herbal medicines, endocrine disrupters, etc.). As a result of its chemical sensory capabilities and gene modulatory functions in controlling cellular detoxification pathways, PXR has been appropriately termed by some as a 'xenosensor' or 'master regulator'. The present review focuses on two facets of this unique receptor. First, its function in maintaining homeostasis that primarily involves rapid and timely elimination of toxic endogenous metabolites and exogenous chemicals. Second, its involvement in dysregulated metabolic conditions (such as osteomalacia) and certain chronic diseases like cancer. When PXR encounters circumstances that are discordant with normal homeostasis, it orchestrates a response by utilizing and modulating the components of the central detoxification defense machinery, i.e. phase I and phase II drug metabolizing enzymes, as well as drug transporters. The presence of PXR in tissues other than the expected ones (liver and intestine) along with the occurrence of various isoforms (three or more) indicates much more diverse roles for this receptor than previously suspected. The possibility of the presence of various PXR isoforms in different tissues suggests utilization of combinatorial mechanisms to regulate different sets of genes under varied physiological and pathogenic conditions. Further studies are expected to divulge important roles of PXR in drug-drug interactions, development of several metabolic disorders and in designing safer therapeutic molecules.

Abstract

Water - a critical input for sustained crop production - is becoming limiting both under rainfed and irrigated condition. It calls for an effective on-farm management of water in field crops through microirrigation (drip-fertigation) that could take care of both drainage during rainy months and supplementary life saving irrigation thereafter. Therefore, the present field study involving three planting configurations and five drip-fertigation schedules were taken up in pigeonpea (long duration) during 2010-12 under Eastern Indo-Gangetic Plains at Kanpur, Uttar Pradesh, India. Significant grain yield advantage (19.6%) was with single drip-fertigation with half of N + K fertilizer at branching over farmers' practice (rainfed pigeonpea, 2858 kg/ha). Drip-fertigation at both branch and pod development also out-yielded (3468 kg/ha) over improved practice (furrow irrigation, 3262 kg/ha). These yield levels realized were close to potential yield (2.5-3.0 t/ha). Twice drip-fertigated plots also had higher yield attributes (pods/plant, 100 seed weight and harvest index), lower water use, greater soil profile water content and water use efficiency (65.1 kg/ha cm), higher plant nutrient (N, P and K) uptake with improved soil nutrient availability and greater net return (INR 9650/ha) over farmers' practice. A case study on a micro-scale was also given which could explore the possibility of out-scaling the technology.

Abstract

Banana breeding programme in India involves maintenance of various genetic resources of banana, of which triploids constitute the maximum share over diploids or tetraploids. RAPD studies conducted in these clones exhibit many distinct genotypes. During a hybridization programme, although many crosses were made, seed set and seed germination were relatively poor in many crosses. Male fertility in banana hybrids could be assessed by pollen output per anther; pollen viability and pollen size, which vary from cross to cross, and also from ploidy to ploidy. Ploidy levels in hybrids are estimated by phenotypic appearance (scoring technique) and confirmed either by stomatal density, size and number of chloroplast per guard cell pair or ischolar_main tip mitosis. However, flow cytometry appears to be the most reliable method in many disputed cases. Generation of parthenocarpic hybrids depends largely upon selection and utilization of parents with parthenocarpic pedigree in a breeding programme. Evaluation of hybrids and parents indicated the nature of inheritance with respect to plant height and suckering habit but no definite trend could be ascribed to the traits of bunch orientation. Diploid x Diploid breeding approach has led to identification of a superior triploid hybrid, NPH 02-01, while Triploid (with AB)xDiploid approach has led to the development of a promising diploid hybrid H.212 and a triploid hybrid H.96/7 (ABB). Similarly, the Triploid x Diploid breeding programme resulted in development of many potential tetraploids that need further improvement. Innovative breeding approaches through in vitro mutation breeding and in vitro polyploidazation resulted in the development of many potentially useful variants. Breeding for resistance against biotic stresses such as Fusarium wilt and nematodes holds promise in banana, and, biochemical mechanisms for resistance in resistant genotypes/hybrids have been elucidated.

Abstract

Objectives: The maximized nano-fluid Nusselt number and minimized pressure drops are the most effective options for obtaining the enhanced thermal frontiers in solar parabolic trough collector. Methods/Analysis: In view of this, numerous researches had proposed hybrid algorithms for the optimization of the thermal analysis. Obtaining Pareto optimal solution, tending to local optimum point and the time consumption are the main drawbacks of the previous algorithms. Hence, in order to overcome the above difficulties, present work proposes a new innovative approach for optimization of thermal analysis in SPTC. Particle Swarm Optimization (PSO) based solution methodology is proposed to gain the benefits of the global optimum solution and overcome the difficulties of the previous approaches. Findings: In this multi objective nonlinear optimization problem, the effect of Nusselt number and pressure drops are considered as the main objectives to obtain the most beneficial values of the design variables. Inlet velocities, concentration ratio of nano-particles and absorber tube diameter are considered as the most preferable design variables in the proposed optimization problem. Application/ Improvement: Five case studies based on different temperature levels are considered to check the suitability of the proposed solution methodology. Results explore the effectiveness of the proposed approach in the optimization of thermal analysis in SPTC.

Abstract

This paper presents a sensitivity based technique for assisting network planners to determine the optimal location and capacity of distributed generators (DG) in a capacity and location constrained distribution network with the objective of minimization of losses in a competitive electricity market. The liberalization of electricity markets has changed the way power generation technologies are valued. The issues that need to be considered in the choice of rating and positioning of DG include both technical and commercial factors. The proposed methodology takes this aspect into consideration and only from among the practicable sites specified by the Distribution system planner both optimal locations and capacity of DGs are determined. It has been applied to a test system of nine bus radial distribution network considered as capacity and location constrained for implementing DG. The technique is efficient and very much useful as it can be directly applied to any distribution network having practical constraints for implementing DG. To show the effectiveness of this technique it was applied to IEEE 6-bus system without any location or capacity constraint and the result was compared with test results of other methods. It is interesting to note that over a wide range of DG penetration the proposed methodology results in largest reduction in loss per unit DG penetration.

Abstract

Laser beam machining (LBM) process deals with material removal with high precision using localized heating characteristics of lasers. Polymers used in different electrical, electronic and Micro-electromechanical systems need to be machined to get desired shape. Machining of these polymers is difficult using conventional machining process. With its large range of process parameters and precise localized heating, LBM provides solution to machining problems of polymers. In the present research, CAD is used to design gear profiles which can be used in electronic systems. These gears are cut from Acrylic film using LBM. The influence of different input parameters namely laser Power, weld Speed and Frequency of laser on profile geometry are studied. Response Surface Methodology (RSM) is used, with the responses chosen as Addendum Diameter (ADD) and Dedendum Diameter (DD). Results are further analyzed and correlations are made using ANOVA approach.

Abstract

The MACE telescope has recently been commissioned at Hanle, Ladakh, India. It had its first light in April 2021 with a successful detection of very high energy gamma-ray photons from the standard candle Crab Nebula. Equipped with a large light collector of 21 m diameter and situated at an altitude of ~4.3 km amsl, the MACE telescope is expected to explore the mysteries of the non-thermal Universe in the energy range above 20 GeV with very high sensitivity. It can also play an important role in carrying out multi-messenger astronomy in India.
