    Crude oil emulsification happens at all stages of crude oil production and processing creating operational problems such as pressure drops in flow lines, corrosion, catalyst poisoning, increase in demulsifier usage and trips in crude oil handling facilities. In order to demulsify the crude oil aptly in-depth analysis of the characteristics of the crude oil is inevitable. This report presents the findings of a series of experiments performed to analyze the oil/ water separation in the presence of varying amounts and types of brine and emulsifiers respectively by using crude oil /water ratios of 70/30, 80/20 and 90/10. The results show the existence of an optimal salinity at which full or partial separation can be achieved without utilizing demulsifiers which can reduce considerable amounts of costs in terms of demulsifiers and other techniques for separatio

    Coronavirus has affected more than 128 million humans worldwide with invasionsin 129 countries across the globe. About 5-10 percent of these patients have pulmonary involvement in the form of COVID Pneumonia leading to ARDS. Although there are no statistics at the moment, trends show that majority will get rid of acute COVID respiratory involvement without any long-term pulmonary complications however several patients will face COVID sequel in the form of post-COVID fibrosis or post-COVID interstitial lung disease. With more and more survivors of COVID-19, long-term pulmonary complications of this infection especially Post-COVID ILD are being recognized by treating physicians ashavinga great impact on patients’functionality and quality of life. Since there is no research-based internationally accepted strategy to prevent and treat Post-COVID ILD, a strategy based upon observations of treating pulmonologists was devised in the COVID management unit at Sahiwal Medical College Sahiwal to prevent and treat Post COVID interstitial lung disease.Keywords:Anti-fibrotic, Fibrosis, Post-COVID sequelae, Post-COVID fibrosis, Post-COVID ILD

    This research study is to investigate crucial factors such as service quality and brand loyalty of the Smartphones users in District Vehari, Punjab, Pakistan. Participants of research study are the students of higher education institutes in District Vehari, Punjab, Pakistan. For the explanation of this research study Independent variable is the four dimensions of customer service quality such as Value-added-services, Mobile devices,Price,Customer services and dependent variable brand loyalty. Researcher has used both explanatory and descriptive approach on this survey based research study. Questionnaire as instrument of data collection is formed by a synthesis of existing constructs in relevant literature. Non-probability technique such as convenience sampling is used for sample design and collected data put in SPSS software version 20 for drawn the deductive conclusion. A series of statistical techniques i.e. frequency distribution, reliability, validity, regression and correlation are conducted to test the hypotheses. The findings show that service quality dimensions as a whole on brand loyalty are significant, since the 14.5 percent of the total variance is explained. Four service quality dimensions are proved to have positive effects on brand loyalty. Those are Value-added-services (standard beta, .155, p, 0.27) Price (standard beta .184, p, 0.009), Mob devices (standard beta .188, p, 0.007), and Customer services (standard beta .158, p, 0.023). Value of research study it is of great importance for mobile operators in an emerging market such as that of Pakistan, to understand what the drivers of brand loyalty are. The present study produced useful findings, which can be utilized by Smartphones provider managers, in their effort to develop and implement successful customer loyalty strategies. The future research study could examine other factors such as trust, attractiveness of alternatives, brand experience and brand image. Moreover, the investigation of the mediation role of switching costs on the link between customer service quality and brand loyalty could enhance the research model.
