It is of great significance to determine soil aggregate stability in predicting agricultural production conditions and erosion risk. However, the problem exposed process evaluating cannot be ignored: Can effects different mechanisms on degree breakdown distinguished by selecting ethanol water as dispersion media? Based this question, natural soils with a gradient textures silty loam loamy clay ...

We show that, in the nite propositional case, traditional circumscrip-tions can be fully described only from the formulas which can never come as a result of the given circumscription (the \inaccessible formulas"). Some work has already been done on the subject. Siegel and Forget have introduced the general notion of X-logic, and they have considered the case of nite proposi-tional circumscript...

This paper studies the properties of eight semantic consequence relations defined from a Tarski-logic L and a preference relation ≺. They are equivalent to Shoham’s so-called preferential entailment for smooth model structures, but avoid certain problems of the latter in non-smooth configurations. Each of the logics can be characterized in terms of what we call multi-selection semantics. After ...

There has been much confusion recently about the relative merits of different approaches, osmotic stress, preferential interaction, and crowding, to describe the indirect effect of solutes on macromolecular conformations and reactions. To strengthen all interpretations of measurements and to forestall further unnecessary conceptual or linguistic confusion, we show here how the different perspec...

background: pancreatitis is a serious complication of endoscopic retrograde cholangiopancreatography (ercp) and may cause significant morbidity and even death. there is no effective prophylactic intervention for patients with average risk yet. this study aims to investigate preventive effect of aggressive hydration for post-ercp pancreatitis. materials and methods: in a double-blind controlled ...

Thermochemical heat storage (TCHS) in salt hydrates attracts increasing interest due to the high energy density combined with loss-free storage. Strontium bromide hexahydrate (SBH), and composites thereof, are often suggested as suitable materials for this application. Although many aspects of SBH have been thoroughly investigated, very little has done on fundamental hydration reaction interact...

The study of frameworks and formalisms for reasoning about action and change [67, 58, 61, 65, 70, 3, 57] has been central to the knowledge representation field almost from the inception of Artificial Intelligence as a general field of research [52, 56]. The phrase “Temporal Action Logics” represents a class of logics for reasoning about action and change that evolved from Sandewall’s book on Fe...
