Integrating their original wine choice into the experiment, each participant evaluated six alternative wines, generating a rich set of data…
Water is an essential component of almost all of the foods that we consume, yet its presence may pass largely unnoticed. We derive considerable quantities of the water that we need to sustain our lives from this ‘hidden’ water in foods. The original idea for this book came from the running of seminars on water activity in bakery products. Much is known about the contribution of water …
Antioxidant activity depends on many factors such as the lipid composition, antioxidant concentration, temperature, oxygen pressure, and the presence of other antioxidants and many common food components, e.g. proteins and water. Antioxidants were first used before World War II for food preservation. These early antioxidants were natural substances. They were, however, soon replaced by synthet…
Abstract: The equal treatment of all citizens is one of the fundamental principles of good administrative practice.

These single species sensitivity distributions are then combined to create …
Abstract: Uremic toxins are associated with various disorders in patients with end-stage renal disease and it is difficult to remove some of these toxins by dialysis. Since some uremic toxins are generated by bacterial metabolites in the colon, oral adsorbents that interfere with the absorption of uremic toxins or their precursors are believed to prevent their accumulation in the body. AST-12…
Recent work on dictatorship has focused on how repression is used by dictators to eradicate political opposition. This article examines evidence from one of the most important dictatorships of the twentieth century to suggest that this may tell only half the story. As Stalin’s dictatorship progressed, repression was increasingly administered neither by the secret police nor the military—as …
