This study investigates changes in temporal trends and spatial patterns of precipitation in Beijing over the last six decades. These changes are discussed in the context of rapid urbanization and the growing imbalance between water supply and demand in Beijing. We observed significant decreases in precipitation amounts from 1950 to 2012, with the annual precipitation decreasing by 32% at a deca...

meteorological stations usually contain some missing data for different reasons.there are several traditional methods for completing data, among them bivariate and multivariate linear and non-linear correlation analysis, double mass curve, ratio and difference methods, moving average and probability density functions are commonly used. in this paper a blended model comprising the bivariate expo...

It is popular belief that the weather is “bad” more frequently on weekends than on other days of the week and this is often perceived to be associated with an increased chance of rain. In fact, the meteorological literature does report some evidence for such humaninduced weekly cycles although these findings are not undisputed. To contribute to this discussion, a modern data-driven approach usi...

It is the common practioe that one, makes sweet-potato Shochu by fermenting the first mash consisting only of rice Koji for about 7 days and then by further fermentation of the second mash prepared by addition of the steamed, crushed sweet-potatoes to the first mash. The authors changed the process in several points: (1) Sweet-potatoes were used as cut, steamed pieces and added on the 9 th, and...

In the course of studies planned on cholesterol metabolism, it was felt necessary to develop a microtechnique for cholesterol that would be suitable for analysis in tissues. It has been pointed out that a direct Liebermann-Burchard reaction method is dependent upon too many variables, some of which cannot be regulated, to be accurate for calorimetric work. There is also the possibility of other...

Struvite precipitation proved to be an effective method of ammonia removal from the landfill leachate from two separate sources. Batch tests for precipitating struvite yielded several different chemical combinations that were effective at removing ammonia from leachate. The struvite precipitate samples were quite heterogeneous in composition, containing a mixture of short and thick crystals, el...
