Maximum Limit

In Islam, clothing does not only function as jewelry and body armor from heat and cold, but more importantly is to cover the nakedness. Al-Qur'an al-Karim shows the obligation of women to cover their bodies in His words, "And let them not show their jewels, except those which (normally) appear from them,". Parts of female limbs that are not allowed to be seen by others are aurat. Islamic scholars agree that all women's bodies are aurat, in addition to the face and two palms. What is meant by the jewelry that appears is the face and two palms. While what is meant by khimar is a headgear, not a face covering like a veil, and what is meant by jaib is chest. The women have been ordered to put a cloth over his head and spread it to cover her chest. By doing library research, that is, research whose main object is books or other sources of literature, meaning that data is sought and found through literature review of books relevant to the discussion, a minimum limit of aurat according to Muhammad Shahrur is that dress cover the juyub, while the maximum limit is dressing which covers all parts of the body besides the face and palms.

The armor-plated dinosaur Ankylosaurus magniventris is redescribed based on specimens from the Hell Creek Formation of northeastern Montana, USA., Lance Formation of Wyoming, USA., and from the Scollard Formation of south-central Alberta, Canada. Except for brief descriptions, most of these specimens have not been described in detail. Ankylosaurus is one of the largest known ankylosaurids, having an estimated length of up to 6.25 m (20.5 ft). It is characterized by a long, low skull having very prominent cranial “horns” that project laterally or dorsolaterally. The body armor includes a large half-ring that sat across the base of the neck and shoulders and a large, low tail club.

A novel methodology for delivering variable drug concentration profiles utilizes a combination of liposomes that destabilize at different rates at body temperature (37° C). Liposomes serve as the mobile drug delivery vehicle and release drugs into the body upon destabilization. Liposome destabilization is studied by monitoring the absorbance spectrum of fluorescent dyes. By combining liposomes of various compositions, concentration profiles that are optimized and tailored to specific patients and applications are feasible.

Ballistic Resistance

It has long been a goal of the body armor testing community to establish an individualized, scientific-based protocol for predicting the ballistic performance end of life for fielded body armor. A major obstacle in achieving this goal is the test methods used to ascertain ballistic performance, which are destructive in nature and require large sample sizes. In this work, using both the Cunniff and Phoenix-Porwal models, we derived two separate but similar theoretical relationships between the observed degradation in mechanical properties of aged body armor and its decreased ballistic performance. We present two studies used to validate the derived functions. The first correlates the degradation in mechanical properties of fielded body armor to the degradation produced by a laboratory accelerated-aging protocol. The second examines the ballistic resistance and the extracted-yarn mechanical properties of new and laboratory-aged body armor made from poly(p-phenylene-2,6-benzobisoxazole), or PBO, and poly(p-phenylene terephthalamide), or PPTA. We present correlations found between the tensile strengths of yarns extracted from armor and the ballistic limit (V50) when significant degradation of the mechanical properties of the extracted yarns was observed. These studies provided the basis for a validation data set in which we compared the experimentally measured V50 ballistic limit results to the theoretically predicted V50 results. The theoretical estimates were generally shown to provide a conservative prediction of the ballistic performance of the armor. This approach is promising for the development of a tool for fielded armor performance surveillance relying upon mechanical testing of armor coupon samples.

The genesis of cardiovascular diseases, namely intra-arterial plaques formation leading to heart attacks, strokes and other vascular complication remains unanswered. To date there is accumulated evidence attributing antioxidant activity (toxic materials) of biochemical events in the human body as probable cause for the illness. Experts in the area of cardiovascular diseases have identified a lack of standardization in disease management; therefore, clinical trials comparing antioxidant agents (such as catalase) have been difficult to compare. Experts are also calling for new knowledge in relation to blood antioxidants physiology. Keratin is a chemical present in cellular structures in the body, also present in the human hair root and shaft. This manuscript presents a new finding, which is documentation of a binding capacity of catalase with keratin. Red blood cell   are the main carriers of the catalase present in the circulatory system; in this manuscript experiments are introduced in support of a hypothesis adding one additional factor in the genesis of atherosclerosis; which is the protein enzyme catalase ever present in erythrocytes reacting with the keratin present in human arteries via an unknown mechanism.
