The distinctive qualities of the cuisine of Hangzhou are the result of its geographical situation, which provided good soils, reliable rainfall, a lake that has been a water source and renowned beauty spot for centuries. The rich water-sources facilitated the development of gastronomy, agriculture, trade and administration, especially after it became the capital of the Southern Sung Dynasty. Ha...

This review explores a coevolutionary framework for the study and management of disease-suppressive soil microbial communities. Because antagonistic microbial interactions are especially important to disease suppression, conceptual, theoretical, and empirical work on antagonistic coevolution and its relevance to disease suppression is reviewed. In addition, principles of coevolution are used to...

An artificial neural network (ANN) model was employed to predict the soil cohesion and soil internal friction angle. The soil samples were collected from different cultivated sites in seven regions in Saudi Arabia. Direct shear box method was used to determine soil cohesion and soil internal friction angle. The input factors to ANN model were soil dry density, soil moisture content and soil tex...
