If the Lonar depression is a meteorite crater, a giant meteorite several-fold richer in nickel and cobalt than the basaltic country rock, should have produced localised enrichment of these metals. Weathering and secondary dispersion, aided by favourable centripetal drainage conditions, should have produced anomalous concentrations of the metals in plants, soil and silt at the site. This is not borne out by the average and below average values of the metals in geochemical samples from the crater area; and recent experimental sampling in the meteorite crater of Arizona also showed similar lack of anomalous metal values. The use of geochemical anomalies in recognising meteorite craters should, therefore, await investigations in other established craters.- Hydrocarbon Prospects of Gondwana Basins in India: Source Rock Studies of Kamthi Sub-Basin of Pranhita-Godavari Graben

Several workers have proposed that coals can be regarded as possible source rocks of oil and gas. The present study was undertaken with the objective of geochemical evaluation of coals and associated shales of Kamthi sub-basin of Pranhita-Godavari Graben. The studies indicate that Barakars of Kamthi sub-basin contain sufficient humic organic matter deposited in intermediate to swampy environment. The organic matter is immature and is capable of generating only gaseous hydrocarbons.Keywords

Allium cepa (onion) seed extract (50 mg/day/rat) was fed orally to male albino rats for 60 days. The body weights were not affected but the weights of reproductive organs were decreased following the treatment. The sperm motility of cauda epididymis and sperm count of cauda epididymis and testis declined significantly leading to negative fertility test.- Trusted Third Party Auditing to Improve the Cloud Storage Security

Introduction of cloud storage service has made the users to access their data anywhere anytime without any trouble. Available systems that provide support for the remote data integrity are useful for quality of service testing but do not deal with server failure or handling misbehaving servers. The security issues that prevail in the data storage at cloud cause lot of threats to the users and cloud service providers. Available systems that provide support for the remote data integrity are useful for quality of service testing but do not deal with server failures or handling misbehaving servers. The proposed system ensures storage integrity and achieves strong cloud storage security with fast data error localization through the results provided by the auditing mechanism that is carried out by the third party auditor. Third party auditor carries out the public auditing in-order to maintain the integrity for the outsourced data that is present in cloud storage. Data integrity in ensured with the help of verification key along with erasure coded data, it also allows in handling the storage correctness and identification of misbehaving cloud server. The Audit Protocol Blocker is introduced in order to monitor the correctness of the Third Party Auditor by preventing the TPA from misusing the privileges that are provided to them by the cloud server.

This paper presents a process technique developed for Thin Film Pattern generation using Photolithography&Wet Chemical Etching on two sides of substrate using Direct Lithography system for use in Thin Film Microwave Integrated Circuits (MICs). Pattern generation on two sides of the substrate is essential where the circuit involves Micro strip to Slotline transition and also where interconnections are required between two circuits positioned back-to-back in a trendy approach to achieve better performance and improved reliability. Direct Lithography is adopted for generation of critical Photo masks or Patterns directly on metallized substrates obviating the need of photo masks. Direct Patterning on substrates has the advantage of fine feature size and fast turn-around time. A method of pattern generation on two sides of the substrate is developed. Details on development of process technique are presented in the paper.Keywords

Objective: The aim of this study is to evaluate the advantage of using 3D laparoscopy over conventional 2D laparoscopy on various operative procedures.
Methods: From April 2012 till April 2017, 1200 patients were selected for various laparoscopic procedures and were divided into two groups. One group of patients were selected for 2-D Laparoscopic surgery and another group for 3-D laparoscopic surgery. Operative performance in both groups was compared in terms of time, stress and confidence of the operating surgeon.
Results: Operative time interval for various procedures was significantly less in 3D Group as compared to 2D Group . Also,it was found that the surgeries performed in 3-D were much easier compared to 2-D in terms of stress and confidence of the operating surgeon.
Conclusion: Advantages of 3D laparoscopy were well appreciated during various operative procedures as compared to 2D laparoscopy.

Sericulture is an emerging agro-based enterprise for small and marginal holding farmers having less capital investment. This enterprise involves two distinct activities viz., silkworm rearing and another important one is mulberry leaf production which decides productivity and profitability in sericulture. Mulberry plant have been found attacked by some major pests along with some natural enemies been observed in this locality. This results in severe economical losses to the sericulture farmers. Considering the farmers interest in adopting chemical measures in controlling the mulberry pests is affecting the silkworm rearing to large extent. Hence, a specific study on pest, seasonal attack, symptoms caused, their characteristic alongwith integrated management approach with special emphasis on bio-control measures needs to be popularized among farmers by intensified extension efforts.Keywords

A study was conducted to assess the impact of different nutrient management practices on soil quality in a permanent manurial experiment cotton field established in 1982 at the Agriculture Research Station of the Tamil Nadu Agricultural University, which falls under the dryland ecosystem of Kovilpatti in Tamil Nadu, India. The experiment was carried out in a randomized block design with nine different treatments. The effect of these treatments in different depths (0–15, 15–30 and 30–45 cm) was compared, and the soil quality index was developed with a total of 27 parameters, including physical, chemical and biological parameters. Principal component analysis was carried out and the principal components with eigenvalue >1 were selected to determine the indicators to be retained in the minimum dataset. The highly weighted variables, viz. field capacity, available water content, cation exchange capacity, nitrogen, phosphorus, potassium, calcium, magnesium, etc. with a variance of 93.57% were retained for MDS. Linear scoring functions were used to transform them into unitless scores ranging from 0 to 1. Three different methods of soil quality were analysed, viz. weighed additive soil quality index (SQIw), additive soil quality index (SQIa) and Nemoro soil quality index (SQIn). In all three methods, the treatment receiving farmyard manure at 12.5 t ha–1 showed superiority in maintaining soil qualityKeywords
