Not only plausible lighting effect is to show the relative position between of the objects, but also to reflect the material of visual appearance of the vir- tual objects. The diffuse-scene rendering reflectance credibility has gradually matured. Global illumination rendering method for the glossy material is still a challenge for the CG research. Because of the shiny materials is highly energy reflection between the com- plex light paths. Whether we trace glossy reflection paths, or use of one-reflection or multi-reflection approximate above complex il- lumination transmission is a difficult working. This paper we gather some commonly used global illumination algorithms recently year and its extension glossy scene improvements. And we introduce the limitation of classical algorithms rendering glossy scene and some extended solution. Finally, we will summarize the illumination rendering for specular scene, there are still some open prob- lems.展开更多

OBJECTIVE： To confirm glossy privet fruit effects on neural cell apoptosis in the cortical parietal lobe and hippocampal CAI region of rat models of vascular dementia using molecular biology techniques. DESIGN, TIME AND SETTING： The neural cell morphology experiment was performed at the Laboratory of Flow Cells and Biochemistry, Academy of Integrative Medicine, Fujian University of Traditional Chinese Medicine, and the Basic Room of Pathology, Academy of Chinese Medicine from December 2006 to May 2008. MATERIALS： A total of 60 Wistar rats were used to establish vascular dementia models using a photochemical reaction method. Glossy privet fruit was purchased from Fujian, China. Hydergine was co-produced by Sandoz, Switzerland and Huajin, China. METHODS： The 60 Wistar rats were randomly divided into 6 equal sized groups （n = 10）, i.e. model, blank, high, moderate and low doses of Chinese medicine, and hydergine control groups. Rats in the model group were treated with distilled water （1 mL/100 g） by gavage following model establishment. Rats in the blank group underwent experimental procedures as for the model group, except that rat models were created without illumination. Rats in the high, moderate and low doses of Chinese medicine groups, and the hydergine control group respectively received high, moderate and low doses of glossy privet fruit, and hydergine suspension （1 mL/100 g） by gavage, once a day, for 30 days. MAIN OUTCOME MEASURES： Morphology of neural cells from the rat cortical parietal lobe and hippocampal CA1 region of all groups was observed with an electron microscope. Positive neural cells in the injury site of the rat cortical parietal lobe and hippocampal CA1 region were investigated using the Fas immunohistochemieal method. Absorbance of Fas-positive neurons was detected by the MPIAS-500 multimedia color imaging analysis system. RESULTS： Neural cells were normal, and展开更多

Methods： Twelve patients with acute Amanita mushroom poisoning received conventional treatment （penicillin and reduced glutathione） combined with oral administration of GGD （treated group）, which was prepared out of 200 g Glossy ganoderma decocted in water to 600 mL, and 200 ml was given once, three times a day for 7 successive days; while conventional treatment alone was given to the other 11 patients assigned to the control group. The therapeutic efficacy and changes in serum levels of total bilirubin （TBil）, bile acids （BA）, alanine transaminase （ALl-）, and aspartate transaminase （AST） activities in the two groups were compared. Results： The cured- markedly effective rate in the treated group was more significant than that in the control group （P〈0.01）. Elevation in TBil, BA, ALT, and AST activities were observed in both groups 3 days after poisoning, which progressively increased thereafter in the control group. In the treated group, they reached their peak on the 3rd day and then declined gradually. The differences between pre-treatment and post-treatment in both groups were obviously significant （P〈0.01）, so were the differences between the two groups at corresponding time points （P〈0.01）. Conclusion： GGD shows excellent clinical efficacy in the treatment of acute Amanita mushroom poisoning and can reduce mortality significantly.展开更多

The amount of epicuticular wax covering the mutant leaves was only approximately 30% that of the wild-type(WT) leaves. The wax crystals of WT plants were columnar and linear, while they were granular and rod-shaped in the mutants. Additionally, in WT cabbage, the primary wax components were alkanes, alcohols, fatty acids, ketones, and aldehydes. There was a significant decrease in the abundance of alkanes and ketones in the wax of the mutants. The glossy-green trait of the mutants may be the result of an inhibited alkane-forming pathway. Higher rates of chlorophyll leaching and water loss demonstrate that the mutant leaves were more permeable and sensitive to drought stress than the WT leaves. Growth curve results indicated that the growth rate of mutant-1 and mutant-3 was slower than that of the corresponding WT cabbage, resulting in shorter plants. However, the growth rate of mutant-2 was not influenced by the lack of coating wax. An investigation of the agronomic traits and heterosis of the glossy cabbage mutants indicated that all five mutants had glossy-green leaves, which was a favorable characteristic. The F1 plants derived from crosses involving mutant-2 exhibited obvious heterosis, suggesting the observed glossy-green trait is controlled by a dominant gene. Therefore, mutant-2 may be useful as a source of genetic material for future cabbage breeding experiments.展开更多

First, in order to keep primitive spherical lights, it uses non-zero solid angle integration instead of a geometric item of traditional Instant Radiosity arithmetic. Second, the formula mode for the light energy allocation of VSLs is improved by the energy distribution, in which the radius of sphere is replaced by the radius of inscribed circle generated by the tangent to the non-zero solid angle of cone. Third, the similar function of judging two point visibility takes place of a cosine term in the approximate equations of the VSLs. Experiments show that blurring or disappearing phenomenon that appear in part of right-angle surface scene is avoided.展开更多
