In order to simulate the instability phenomenon of a nonaqueous phase liquid(NApL) dissolution front in a computational model, the intrinsic characteristic length is commonly used to determine the length scale at which the instability of the NApL dissolution front can be initiated. This will require a huge number of finite elements if a whole NApL dissolution system is simulated in the computational model. Even though modern supercomputers might be used to tackle this kind of NApL dissolution problem, it can become prohibitive for commonly-used personal computers to do so. The main purpose of this work is to investigate whether or not the whole NApL dissolution system of an annular domain can be replaced by a trapezoidal domain, so as to greatly reduce the requirements for computer efforts. The related simulation results have demonstrated that when the NApL dissolution system under consideration is in a subcritical state, if the dissolution pattern around the entrance of an annulus domain is of interest, then a trapezoidal domain cannot be used to replace an annular domain in the computational simulation of the NApL dissolution ***, if the dissolution pattern away from the vicinity of the entrance of an annulus domain is of interest, then a trapezoidal domain can be used to replace an annular domain in the computational simulation of the NApL dissolution system. When the NApL dissolution system under consideration is in a supercritical state, a trapezoidal domain cannot be used to replace an annular domain in the computational simulation of the NApL dissolution system.

Multiple origins of charnockite in the Mesoproterozoic Natal belt,Kwazulu-Natal,South Africa

Four different varieties of charnockitic rocks, with different modes of formation, from the Mesoproterozoic Natal belt are described and new C isotope data presented. Excellent coastal exposures in a number of quarries and river sections make this part of the Natal belt a good location for observing charnockitic field relationships. Whereas there has been much debate on genesis of charnockites and the use of the term charnockite, it is generally recognized that the stabilization of orthopyroxene relative to biotite in granitoid rocks is a function of low aH2O （-- high CO2）, high temperature, and composition （especially Fe/（Fe ＋Mg））. From the Natal belt exposures, it is evident that syn-emplacement, magmatic crystallization of charnockite can arise from mantle-derived differentiated melts that are inherently hot and dry （as in the Oribi Gorge granites and Munster enderbite）, as well as from wet granitic melts that have been affected through interaction with dry country rock to produce localized charnockitic marginal facies in plutons （as in the portobello Granite）. Two varieties of post-emplacement sub-solidus charnock- ites are also evident. These include charnockitic aureoles developed in leucocratic, biotite, garnet granite adjacent to cross-cutting enderbitic veins that are attributed to metamorphic-metasomatic processes （as in the Nicholson＇s point granite, a part of the Margate Granite Suite）, as well as nebulous, patchy charnocki- tic veins in the Margate Granite that are attributed to anatectic metamorphic processes under low-aH2O fluid conditions during a metamorphic event. These varieties of charnockite show that the required physical conditions of their genesis can be achieved through a number of geological processes, providing some important implications for the classification of charnockites, and for the interpretation of charnock- ite genesis in areas where poor exposure obscures field relationships.

Morphometric analysis of the drainage system and its hydrological implications in the rain shadow regions, Kerala, India

Journal of Geographical Sciences 2011年第6期21卷 1077-1088页

The rain shadow regions requisite a comprehensive watershed development and management plan for sustainable water resources management. The pambar River Basin （pRB） lies on the rain shadow region of the southern Western Ghats, India, where climate showed marked intra-basin variation. A morphometric analysis was done to evaluate the drainage characteristics of pRB using topographical maps and digital elevation data. pRB was divided into eighteen 4th order basins （SB1-SB18）, distributed along various climatic gradients. Lower order streams mostly dominate pRB and drainage pattern is a function of relief and structure. The terrain is highly dissected and prone to soil erosion during heavy storms and the elongated shape of pRB enables easier flood management. The influence of climate on drainage characteristics was evidently emphasized in basin morphometry. Four distinctively different classes were identified based on the morphometric similarities. The significance of morphometric analysis on the hydrological characterization is discussed and the relevance of the present study in water harvesting has been explicated.

IMpLEMENTATION OF MECHANISTIC CATTLE NUTRITION MODELS UNDER FIELD CONDITIONS

首届中国牛业发展大会

作者： thomas p Tylutki Agricultural Modeling and Training Systems LLC

Executive Summary Cattle nutrition models range in complexity from simple tabular systems (e.g.1984 Nutrient Requirements of Beef Cattle) to advanced mechanistic models (e.g. the Cornell Net Carbohydrate and protein System). As new research is published, these models continue to become more complex. Analogous to the increased level of complexity seen in cattle nutrition models is the evolution of computer power. In 1989, the Intel 486 processor was state of the art and users were accustomed to the MS-DOS operating system. Also in this year, the National Research Council
