Every May 29th the World Gastroenterology Organization (WGO) celebrates World Digestive Health Day (WDHD) and initiates a worldwide public health campaign through its 110 national societies and 50,000 members. Each year focuses on a particular digestive disorder in order to increase general public awareness of prevention and therapy. 2010 is dedicated to inflammatory bowel disease (IBD). Upon t...

Edible fats and oils are produced by three main industries: oil, margarine and rendering. As margarine manufacture requires only substances that have already undergone refining, the only waste water comes from rinsing the equipment and premises. The oil industry with its different phases of refining uses large quantities of water but could cut its consumption by a more rational organization of ...

The development of new gearbox designs, the quality requirements as well as the growing ecology consciousness influenced the development of synthetic transmission gear oils with extended replacement interval. Monitoring of lubricant operating properties in the application and the analysis of the gained results provide the lubricant replacement at the right time. In this way the costs of lubrica...

Polyhydroxyalkanoates (PHA) are efficient, renewable and environment friendly polymeric esters. These polymers are synthesized by a variety of microbes under stress conditions. This study was carried out to check the suitability of waste frying oil in comparison to other oils for economical bioplastic production. Six bacterial strains were isolated and identified as Bacillus cereus (KF270349), ...

The quality and reliability of consumables, including gear oils, results in the failure-free operation transmission components heavy trucks. It is known that oil viscosity essential for all lubricated tribopairs wear friction reduction vehicles with a gearbox. Viscosity may be influenced by contamination products can impart on oil. Oil also affect lubrication efficiency boundary conditions gear...

Speed increase transmission gear box is the primary vibration and noise source of wind turbine, Operational modal method was adopted to collect impact data and response data of each point based on the gearbox test model. ANSYS finite element model is established to simulate the wind turbine gearbox. Then the modal frequencies of the two methods were compared to ensure the test model is correct....

As one of the major biofuels to replace fossil fuel, biodiesel has now attracted more and more attention due to its advantages in higher energy density and overall less greenhouse gas generation. Biodiesel (fatty acid alkyl esters) is produced by chemically or enzymatically catalyzed transesterification of lipids from microbial cells, microalgae, oil crops, or animal fats. Currently, plant oils...
