| calculating the ph of a weak base solution: pH of the Skin: Issues and Challenges C. Surber, C. Abels, H. Maibach, 2018-08-21 The concept of expressing acidity as the negative logarithm of the hydrogen ion concentration was defined and termed pH in the beginning of the 20th century. The general usefulness of the pH concept for life science was recognized and later gained importance to analytical research. Reports on results of pH measurements from living skin established the term acid mantle - the skin's own protective shield that maintains a naturally acid pH. It is invisible to the eye but crucial to the overall wellbeing of skin. Chronic alkalization can throw this acid mantle out of balance, leading to inflammation, dermatitis, and atopic skin diseases. It is therefore no surprise, that skin pH shifts have been observed in various skin pathologies. It is also obvious that the pH in topically applied preparations may play an important role. Optimal pH and buffer capacity within topical preparations not only support stability of active ingredients and auxiliary materials, but may also increase absorption of the non-ionized species of an acidic or a basic active ingredient. They may even open up opportunities to modify and correct skin pH and hence accelerate barrier recovery and maintain or enhance barrier integrity. Further efforts are needed to standardize and improve pH measurements in biological media or pharmaceutical/cosmetic vehicles to increase and ensure quality, comparability, and relevance of research data. In this volume, we present a unique collection of papers that address past, present and future issues of the pH of healthy and diseased skin. It is hoped that this collection will foster future efforts in clinical and experimental skin research. |

| calculating the ph of a weak base solution: Poverty in the Philippines Asian Development Bank, 2009-12-01 Against the backdrop of the global financial crisis and rising food, fuel, and commodity prices, addressing poverty and inequality in the Philippines remains a challenge. The proportion of households living below the official poverty line has declined slowly and unevenly in the past four decades, and poverty reduction has been much slower than in neighboring countries such as the People's Republic of China, Indonesia, Thailand, and Viet Nam. Economic growth has gone through boom and bust cycles, and recent episodes of moderate economic expansion have had limited impact on the poor. Great inequality across income brackets, regions, and sectors, as well as unmanaged population growth, are considered some of the key factors constraining poverty reduction efforts. This publication analyzes the causes of poverty and recommends ways to accelerate poverty reduction and achieve more inclusive growth. it also provides an overview of current government responses, strategies, and achievements in the fight against poverty and identifies and prioritizes future needs and interventions. The analysis is based on current literature and the latest available data, including the 2006 Family Income and Expenditure Survey. |
