    Human papillomavirus (HPV) infection is among the most common viral infections of the reproductive tract. Out of more than 100 different types of HPV identified so far, only a few (termed as “high-risk” subtypes) are associated with cervical cancer. On the other hand, “low-risk” subtypes are associated with genital warts and other benign changes in cervical and oral mucosa. Majority of the HPV infections usually clear up without any intervention within a few months. However, a fraction of HPV infections, such as those with types 16 and 18, can become persistent which may lead to the development of anogenital or cervical cancers. HPV subtypes 16 and 18 together are responsible for approximately 70% of all cervical cancer cases, the fourth major cause of cancer-related deaths in women. In the absence of any specific treatment options, preventive measures are considered as cornerstone of strategies aimed at curbing the burden of this disease. This chapter presents a comprehensive review of strategies that can be employed to prevent and eradicate HPV infection. Minimizing the exposure to HPV risk factors such as unprotected sex, multiple sex partners, early age sex, and not being circumcised, can reduce the chances of getting HPV infection to a significant level. Mass screening programs have also been effective in HPV eradication. Nevertheless, immunization against HPV has proven to be the most promising strategy in fight against HPV. Virus-like particles based on bivalent, quadrivalent, and nonavalent anti-HPV vaccines have been licensed and are available in market under the trade names of Cervarix®, Gardasil®, and Gardasil9®, respectively. Various clinical trials and population-based studies have demonstrated high levels of efficacy for all the three vaccines in preventing type-specific malignancies

    Many hazard identification and risk management techniques are used in chemical process industries (like HAZOP, QRA, PHA) at the design stage and in operational plants to ensure smooth and safe run of all l plant operations and activities.. The implementation of these techniques is robust, yet accidents happen in chemical process industry. The investigation of such accidents has shown that the active measures for prevention are inadequate and are often poorly designed. The purpose of this manuscript is to study a gas processing facility and identify the needs for such active measures which will act as first line of intervention to fire incidents, that will help in avoiding the escalation of small incident towards a catastrophic event. &nbsp

    Promoting corporate social responsibility (CSR) has become a crucial task in marketing strategy for the banks. Due to growing interest of academicians and policy makers, the concept of CSR is receiving a lot of attention in recent times. With this background, the present research empirically investigates how banks’ CSR activities generate positive organizational outcomes in the form of corporate reputation (CR), customer loyalty (CL) and organizational performance (OP). Working with a sample of 308 banking customers in Pakistan, Structural equation modeling technique was used for data analysis of present write-up. The results show that CSR positively influences CR, CL and OP in banking sector of Pakistan . Banks must include CSR in their long-term strategic plans to improve overall customer experience because banks’ CSR activities result in customer identification which improves their repute and ultimately enhances OP.&nbsp

    Success of Aquaculture Industry with New Insights of Using Insects as Feed: A Review

    Get PDF
    Most of world's fish and seafood are produced by aquaculture, which is one of the biggest contributors to the world's food security. The substantial increase in prices of conventional feed ingredients and the over-exploitation of natural resources are some of the biggest constraints to aquaculture production. To overcome this stress, different approaches and techniques are used, among which the use of non-conventional feed ingredients in the aquaculture sector is the most recent approach. Different non-conventional feed ingredients such as plant-based products, algae (both micro and macroalgae), single-cell protein (bacteria and yeast), and insect meal are currently used in aquaculture for sustainable food production. Amongst all these novel ingredients, insects have greater potential to replace fishmeal. The existence of about 1.3 billion tons of food and agriculture waste from the food chain supply poses a serious environmental threat. Insects are tiny creatures that can thrive on organic waste and thus can convert the waste to wealth by the bioconversion and nutritional upcycling of organic waste. Insects have the potential to recover nutrients from waste aquaculture products, and many fish species feed on insects naturally. Therefore, employing insects in the aquaculture sector to replace fishmeal is an eco-friendly approach. The present review briefly highlights emerging non-conventional feed ingredients, with special attention given to insects. The current review also focuses on the nutritional value of insects, factors affecting the nutritional value of insects, potential insects that can be employed in the aquaculture sector, the physiological response of fish when fed with insect meal, techno-functional properties of insect meal, and emerging approaches for addressing possible downsides of employing insect meal in fish diets. Finally, it suggests avenues for further research into these inventive fishmeal replacements

    Initial Environmental Examination for Power Plant in Local Sugar Mill

    This research presents the IEE (Initial Environmental Examination) and EIA (Environmental Impact Assessment) for sugar mills as power generation business. The study evaluates the proposed project according to the environmental assessment requirements of the Pakistan Environmental Protection Agency. The study has been conducted using standard environmental assessment methodology with the consultation of national and international environmental guidelines such as World Bank environmental and International Finance Corporation (IFC). The installation of 100 MW cogeneration thermal power plant adjacent to existing sugar mill located in district Muzaffargarh has been considered as a case study.  It has been concluded that the residual impacts of the proposed operation will be of minor significance and careful implementation of the Environmental Management Plan (EMP) will ensure that environmental impacts are managed
