    Assay of iron in pharmaceutical preparations by spectrophotometry and computational scanning densitometry
    (UMT, Lahore, 2025) Abdul Manan Khalid
    Iron is an essential mineral that is used in manufacturing, painting & coating, water treatment, cosmetics and human health to cure anemia, memory issues and other deficiencies. Without the use of sophisticated instrumentation, this study attempts to assay iron in pharmaceutical preparations to ensure accurate dosage and quality control utilizing portable, easy to use, rapid, and innovative approaches. In this work, a novel technique based on computational scanning densitometry (CSD) was used to assay Iron in pharmaceutical preparations. To confirm the accuracy and precision of the suggested approach, spectrophotometry was also used as a reference method to analyze the pharmaceutical preparations. The reduction of Fe3+ occurs in which ascorbic acid act as a reducing agent to reduce the Fe3+ to Fe2+ . A Prussian blue complex (Fe4[Fe(CN)6]3) was formed when the Fe2+ combines with potassium ferricyanide [K3Fe(CN)6], and its integrated density was calculated by using Adobe Photoshop. Different factors affecting the color density of Prussian blue like concentration of reagents, pH, time, temperature as well as volume of reagents were studied. Thus, the results of computational scanning densitometry and spectrophotometry were compared. After comparing several color models for regression value, the greyscale model gave the best R2 value. Computational scanning densitometry proved itself a simple, quick, precise and reliable technique. Furthermore, the novel approach has several benefits, including small sample usage, faster analysis, improved accuracy, ease of handling and computer usage.

    Standardization of Body Sizes for Menswear in Pakistan
    (UMT.Lahore, 2016) Abdul Manan Khalid
    When we talk about menswear, good fit and clean look are the key points to success for a brand to survive. It is significant to pay attention to every little detail where menswear is concerned, so that they can make them look truly stylish. It is necessary for a brand to fix their size system to achieve a customer's trust and satisfaction. A good fit can only be achieved through actual sizing structure of the body. Unfortunately there is no size system in Pakistan and standard sizes are followed through perception in today’s huge garment industry. Good fit is only possible when you have comprehensive research on the society, their living style, eating habits, environment, weather etc
