This paper presents a multiphysics approach for characterizing flow-induced vibrations (FIVs) in a subsea jumper subject to internal production flow, downstream slug, and ocean current. In the present study, the physical properties of production fluids and associated slugging behavior were characterized by pvtsim and olga programs under real subsea condition. Outcomes of the flow assurance studies were then taken as inputs of a full-scale two-way fluid–structure interaction (FSI) analysis to quantify the vibration response. To prevent onset of resonant risk, a detailed modal analysis has also be carried out to determine the modal shapes and natural frequencies. Such a multiphysics approach actually integrated the best practices currently available in flow assurance (olga and pvtsim), computational fluid dynamics (CFD), finite element analysis (FEA), and modal analysis, and hence provided a comprehensive solution to the FSI involved in a subsea jumper. The corresponding results indicate that both the internal production flow, downstream slugs, and the ocean current would induce vibration response in the subsea jumper. Compared to the vortex-induced vibration (VIV) due to the ocean current and the FIV due to the internal production flow, pressure fluctuation due to the downstream slug plays a dominant role in generating excessive vibration response and potential fatigue failure in the subsea jumper. Although the present study was mainly focused on the subsea jumper, the same approach can be applied to other subsea components, like subsea flowline, subsea riser, and other subsea production equipment.

The purpose of this cross-sectional web-based study was to assess the prevalence of perceived stress among dental faculties of Government Dental Colleges across the state of Kerala, India, during the Corona Virus Disease 2019 (COVID-19) pandemic, which has a huge impact on both physical and psychological well-being of persons all over the world. Human transmission of this disease occurs mainly through droplet inhalation and hence, direct contact with mucous membranes and saliva is considered risky. The study was conducted using a five-point scale PSS10 (Perceived Stress Scale) questionnaire. Comparison between study groups (gender and age group) with continuous variables (PSS score) was done using independent t test. The chi-square test was used to compare the age group and gender with PSS categories; low, moderate and high. The mean PSS score of the respondents was 17.43 ± 6.45 with a range from 2 to 35 with women having higher mean stress scores (18.15 ± 6.54) compared to men (16.46 ± 6.24). Participants aged 40 years and less reported higher PSS scores (18.60 ± 6.40) compared to the older age group (16.14 ± 6.30). Since varying amounts of stress are present in ABOUT THE AUTHOR

Purpose: Role ofknowledge level of employees in customer relationship management with special reference to LIC. In order to investigate a range of factors of CRM in LIC of India. In this specially concentrate to understand the knowledge level of the employees as perceived by the customer.   Theoretical framework: The theoretical frame work of the study, CRM is assessed the Knowledge level of employees isthe independent variables and the customer satisfaction is the dependent variable in the study. CRM is shown influencing the customer satisfaction. The significant influences of the factors on CRM vary according to different demographic profiles and views on policy holdings.   Design/Methodology/Approach:Descriptive research design was use in this studyThe prime data were collected from the sample of the respondents was identified from the total population of lic policy holders. The statistical analysis was carried out with the application of SPSS package. Both Descriptive and Inferential Analysis were carried out. The tools for the Inferential Analysis included Independent Sample t-test, One Way ANOVA, Chi Square Test, Friedman Test, Correlation and Regression.   Findings: The findings of the study based on output of the study. Henceforth reasoned that there is a huge distinction between mean positions towards Factors of Customer Relationship Management. In light of mean position, Customer Engagement is the main variable of CRM, trailed by Deployment of Modern Technology Knowledge level of the Employees etc. There is no importance contrast between capability of representatives concerning the Factors of Knowledge level of the Employees, There is significance contrast among male and female of laborers with respect to the Factors of Knowledge level of the Employees. The connection coefficient between Perception on Explanation of various items and Ready for Clarification is positive connections between Perception on Explanation of various item and Perception on Ready for Clarification .The connection coefficient between Explanation of various item and Recommending Right Schemes is positive connections between Explanation of various item and Recommending Right Schemes. The connection coefficient between Perception on Explanation of various items and Knowledge about Procedure is positive connections between Perception on Explanation of various items and Easy Acquisition of Policy and also different variables are decidedly corresponded with one another.   Research, practical & social implications:This article express a different perspective on CRM in LIC.The results of this study indicate knowledge level of employees has a strong impact on customer satisfaction. Therefore top management should implement latest technology based increase the knowledge level of employees. To increase the knowledge level of employees to help the increasing satisfaction level of policy holders. It is intended to help guide and reassure current and potential Ph. D students.   Originality/value:To date, no systematic review has been conducted on the knowledge level of employees in LIC .This paper makes an important contribution to knowledge level of employees in CRM.
