A Study on Awareness and Satisfaction towards Employee Welfare Measures

The employees are considered as major resources of all organisations including service as well as manufacturing industries. So in the present day of business world, the companies are giving more benefits to their employees and maintaining good standard measures to make them satisfy in the organisation. The present study is on the above subject which studies the welfare measures. Therefore the reason of the study is to find out how welfare measure are provided by the private organisation and how the employees are satisfied with the company accommodation given to the employees which plays a very important role in the employee satisfaction and their life in the organization. The study found that the employee welfare measures are highly satisfactory in their concern which was done through perfect analysis & interpretation. This study would be helpful for the company and also to improve some welfare and safety activities inside the company

ANTIOXIDANT PROPERTIES CLADOPHORA SOCIALIS GREEN ALGAE OF SEAWEEDS COLLECTED FROM RAMESWARAM IN INDIA

Objective: Cladophora Socialis (CS) green algae are one of the most common seaweed water filamentous green algae reported to three different extracts (Hexane, Ethyl acetate and Acetone) have antioxidant activities. Methods: The evaluation of antioxidant properties was determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azinobis 3ethylbenzthiazoline-6-sulphonic acid (ABTS), ferric reducing antioxidant power (FRAP), nitric oxide scavenging assay (NO), reducing power, hydroxyl, superoxide radical scavenging (SOD), hydrogen peroxide radical assay, the metal chelating activity as well as phosphomolypdenum assay. Results: Among the tested CS, the maximum antioxidant activity was recorded in the extract of CS. Whereas Acetone extract of green algae showed good antioxidant potential. Conclusion: This study suggests that green algae Acetone extracts contain different potential antioxidant compounds capable to scavenge different types of free radicals

Determination of Hospitality Services Quality and Customer Satisfaction – a Holserv Approach

This study examines the relationship between quality of perceived service and level of satisfaction customer attained in Tourism. Although the aforesaid relationship discussions proliferated, studies have employed customised SERVQUL for tourism remains dearth. This research attempts to fulfil the gap by using HOLSERV measurement instrument. HOLSERV is developed to measure the service quality in tourism, comprised with three factors named employee, tangibles, and reliability. Data have been collected from guests of the luxury hotels located in Pondicherry (Puducherry). 344 samples were used for data analyses after eliminating the unusable data by preliminary psychometric test. Confirmatory Factor Analysis (CFA) followed by Structural Equation Modelling (SEM) was employed to examine the postulated relationship. The results supported the proposed hypotheses. Employees, tangibles, and reliability are confirmed as factors of hospitality service quality by CFA. Employee factor ascertained to be an important factor by SEM. From the results and findings of this study, implications have been drawn, limitations were given, and recommendations were made for future researcher

Structure of a translocation signal domain mediating conjugative transfer by Type IV secretion systems

Relaxases are proteins responsible for the transfer of plasmid and chromosomal DNA from one bacterium to another during conjugation. They covalently react with a specific phosphodiester bond within DNA origin of transfer sequences, forming a nucleo-protein complex which is subsequently recruited for transport by a plasmid-encoded type IV secretion system. In previous work we identified the targeting translocation signals presented by the conjugative relaxase TraI of plasmid R1. Here we report the structure of TraI translocation signal TSA. In contrast to known translocation signals we show that TSA is an independent folding unit and thus forms a bona fide structural domain. This domain can be further divided into three sub-domains with striking structural homology with helicase sub-domains of the SF1B family. We also show that TSA is part of a larger vestigial helicase domain which has lost its helicase activity but not its single-stranded DNA binding capability. Finally, we further delineate the binding site responsible for translocation activity of TSA by targeting single residues for mutations. Overall, this study provides the first evidence that translocation signals can be part of larger structural scaffolds, overlapping with translocation-independent activities

Hydrodynamic changes due to large seabed installations in coastal waters off west coast of India

Offshore marine environment can very well be utilized for mass storage of liquids which are not harmful to that environment. Improper placement of large tanks on the seabed, to store large quantities of liquids, would adversely affect the hydrodynamics of adjoining environment. Thorough understanding on the hydrodynamics of the adjoining environment is thus required before and after placing such tanks so as to properly plan the placement of these large tanks. A two dimensional numerical hydrodynamic model is used to study influence of placing large number of tanks in a dynamic marine environment. Cylindrical tanks (5 m dia.) are arranged in three rows with 50 tanks placed in each row with their length (100 m) aligned perpendicular to the coast. These tanks cover an area of about 36000 m2 and are placed on seabed in water depths about 15 m. Hydrodynamic simulations carried out with tidal forcing for cases of (a) before and (b) after placement of tanks showed that current speeds increase up to 65% in the region where the tanks are placed compared to currents without placement of tanks. However, up to 85% increase in current speeds is observed in regions beyond the tanks. In this manuscript results of the effects on the hydrodynamics of a region due to placing large number of tanks in shallow waters are presented

Production of mother oysters of Pinctada fucata (Gould) by manipulation of stocking density

Marine pearl culture is a multifaceted technique involving three different kind of works namely i) seed production, ii) farming and mother oyster development and iii) nucleation and pearl production. To make the technique more viable and economically feasible it is imperative to make critical analysis of the various technicalities involved in the culture strategy. Hence a commercial level scheme on marine pearl culture in the inshore waters of Gulf of Mannar (GOM) was taken up during 1998-2004 at Mandapam Regional Centre of Central Marine Fisheries Research Institute (CMFRI). Critical analysis of the data revealed that a definite upgradation of pearl culture technology is required in many components coupled with policy decisions by the State Government. The present paper focuses on a single major problem of production of mother oysters for nucleation and pearl production on a continuous and commercial scale of operation. The culture method, appropriate farm management, stock density, growth and survival, culling and their effect on the production of mother oyster suitable for nucleation are presented in the paper

Structure of the Bacterial Sex F Pilus reveals an assembly of a Stoichiometric Protein-Phospholipid Complex

Conjugative pili are widespread bacterial appendages that play important roles in horizontal gene transfer, in spread of antibiotic resistance genes, and as sites of phage attachment. Among conjugative pili, the F “sex” pilus encoded by the F plasmid is the best functionally characterized, and it is also historically the most important, as the discovery of F-plasmid-mediated conjugation ushered in the era of molecular biology and genetics. Yet, its structure is unknown. Here, we present atomic models of two F family pili, the F and pED208 pili, generated from cryoelectron microscopy reconstructions at 5.0 and 3.6 Å resolution, respectively. These structures reveal that conjugative pili are assemblies of stoichiometric protein-phospholipid units. We further demonstrate that each pilus type binds preferentially to particular phospholipids. These structures provide the molecular basis for F pilus assembly and also shed light on the remarkable properties of conjugative pili in bacterial secretion and phage infection
