    As of 2011, a survey was conducted by Li within the academic domain which further proposed a study that among all survey respondents over half of the respondents preferred and used electronic books in their work. According to the research, 2 billion books are produced in the US alone annually which requires the consumption of 32 million trees. One A4 sheet takes 10 litres of water to be produced. No harm can overshadow the alarming environmental harm our planet goes through to produce paper for the books each year. It is depleting our water and destructing our planet by adding to the global warming crisis. No matter how successful a business is, there comes a time when you need to find a new sales channel. Printed books have reigned the world for thousands of years, but now it is time for it to evolve too. In this digital era where everyone is shifting towards online business, e-books have also gained immense importance amongst people. The rapid increase of e-Books has modified the interface of library catalogues by providing the members with access to more information. Rosso identified the main purpose in preferring e-books to include mobility, saving physical space, saving time and money, and ease-of-use while enhancing the learning process. A person can carry the utmost 2 to 3 books with himself anywhere to read, instead of packing a ton of books to read; he can download an e-book application so he could carry thousands of books without weighing less with him throughout the world wherever he goes. Every time a person requires reading a book, he has to go to a book shop and buy the book on his own but the e-book application enables the user to download books that save the user time of going somewhere to buy the hardcopy as well as the printing cost. Digital books let the user read his favourite books on the go with enabling him to get all the information he requires under a single screen. Hence, our final year project proposes a solution to all these problems by creating an E-book Application that has all the required features which the other applications lack and in a low pricing model. We will make a complete web application for online reading.

    Nutritional Evaluation of Selected Fresh Fruits as a Source of Water -soluble Vitamins to Meet Daily Required Intake
    (Library Information Services COMSATS University Islamabad Lahore Campus, 2022-02-26) Misbah Murshid; SP21-R06-012; Dr. Muhammad Javid Iqbal; LHR TP 8031
    Apple, Banana, and Guava are the most widely accessible fresh fruits across the world. In this study, we analyzed the water-soluble vitamin content of Vitamin B1 (thiamine), Vitamin B2 (riboflavin), Vitamin B3 (niacin), Vitamin B5 (pantothenic acid), Vitamin B6 (pyridoxine), Vitamin B9 (folic acid) and Vitamin C (ascorbic acid) in these locally available fruits from Pakistan. Using a reversed-phase highperformance liquid chromato- graphic approach with isocratic elution, a comparative simultaneous quantitative analysis of these water-soluble vitamins is performed at 25◦C. Vitamins were separated chromato- graphically in a 50-minute run time at 1ml/min flow rate on an Agilent 5, TC-C18 (250 4.8mm, 5m) and Perkin Elmer Series 200 HPLC instrument with UV/Vis detection at a wavelength of 270nm using a mobile phase of Methanol and buffer solution (1 hexane sulfonic acid sodium salt solution with pH 4.3) at a fixed ratio of 15%:85% respectively. According to the findings of the analysis that these fruits provide a sufficient number of water-soluble vitamins, particularly vitamin C, which may significantly contribute to food security, nutrition, therapeutic effects, and health. However, except for Vitamin B3 (in Apples) and B9 (in Bananas), the percentage contribution to the DRI value of water- soluble vitamins in these fruits was lower than the recommended DRI levels. It is essential that the individual consume fruits in a varied manner in combination with other fruits thus preventing monotony and therefore ensuring a greater daily intake of these vital nutrients.
