Women living with HIV are at risk for cervical dysplasia and cancer worldwide. In 2015, the World Health Organization (WHO) recommended that testing for high-risk HPV (hrHPV) infection be incorporated into cervical cancer screening programs using molecular nucleic acid tests (NATs) but this has not previously been done in Uganda.

N-Guanylurea dinitramide (GUDN), also known as FOX-12, is indeed a fascinating organic dinitramide salt with high insensitivity and good thermal stability. It shows great promise for use in next-generation insensitive munitions. In this study, GUDN was synthesized through the nitration reaction of ammonium sulfamate salt with an acid mixture (HNO3/H2SO4) and guanylurea salts in water.

In ebook "Yeast protocols (Third edition)" the first eight chapters describe some basic protocols in yeast culture and genomic manipulation. Chapters 9–12 describe protocols that study certain organelles such as mitochondria and peroxisomes, and their functions in autophagy. Chapters 13– 19 are dedicated to some assays commonly used in yeast-based studies. These protocols can be potentially adapted to other organisms. The last two chapters describe two commonly used yeast-based protocols that are used to study not only yeast genes but also genes and gene products from other organisms.

Ebook "Chemistry and technology of honey production" explains and discusses honey and its production from a chemical perspective. It outlines why honey is a special and unique food, being produced by bees from the nectar of plants or from secretions of living parts of plants. Although glucose and fructose are the main constituents of honey, its overall composition is far from being simple or uniform: other substances such as organic acids, enzymes, or minerals are found in varying amounts.

Ebook "Surface chemistry of aqueous corrosion processes" starts with a timely and in-depth review of Acid-Base Properties of Surface Oxide Films. Acid-base properties are significant in various surface phenomena such as general and localized corrosion, corrosion inhibition by organic molecules, and the adhesion of organic polymers to oxide-covered metals. This review also discusses the relationship between the two measures of surface charge, the isoelectric point of the oxide film and the potential of zero charge of the oxide-covered metal.
