城市道路单向交通组织前后的环境效益评价

传统的单向交通研究大多集中于基础理论研究而缺乏实施前后的效果评价．在选取长春市城市典型拥堵区域晚高峰进行车载排：故测试、道路结构调查和交通流调查的基础上,基于顺时针组织单向交通,并结合区域公共交通实际设置逆向公交车道,采用交通仿真软件Q-Paramics进行单向改造前后的交通仿真,将基于比功率的排放模型和交通仿真模型通过速度和加速度作为输入输出参数结合,从而定量评价单向改造前后区域的机动车3种排放污染物的瞬态排放率及排放总量．研究结论表明：通过合理组织单向改造、设置逆向公交车道及交叉口时空资源的优化设计,区域机动车3种排放污染物的瞬态排放率均有所减少,3种排放污染物的小时排放量和排放总量均有降低,区域内机动车每小时排放总量降低了4．62％．

Preparation and Characterization of the Covalent-Integrated Poly（lactic acid） and Scrap Leather Fiber Composites

Scrap leather fibers (SLFs) modified with active silane containing epoxide groups were incorporated into poly(lactic acid) (PLA) modified by vinyl trimethoxysilane, i.e., the PLA/SLF composites were prepared for bio-composites by solvent compounding technology in this article. The effects of silane coupling agents on the structures of PLA and SLF molecules were examined, and the mechanical properties and thermal stability of PLA/SLF composites were also measured. The results of Fourier-transform infrared spectroscopy (FTIR) had proved that silane had been incorporated successfully to PLA and SLF molecules by means of the solvent technology. Scanning electric microscopy (SEM) was used to investigate both the changes in shapes between the pristine SLFs and the treated SLFs and the microscopic structures of composites. According to SEM results, it was shown that there were some significant differences between the untreated and treated SLFs, and a double continuous phase structure had occurred in PLA/SLF composites due to the excellent dispersion of SLFs in matrix. The addition of the treated SLFs into PLA resulted in a distinct improvement of the impact and tensile strengths. When the mass fraction of the treated SLFs was 15%, the notched impact strength and tensile strength of PLA/SLF bio-composites were improved by 34.4% and 21.2% compared with the pristine PLA, respectively. Additionally, with the increase of the modified SLFs content, the thermal stability of PLA/SLF bi-composites was apparently improved. The macroscopic properties of bio-composites were found to be strongly dependent on their components, concentration, dispersion and resulted morphological structures.

Genome-wide profiling identifies Saccharomyces cerevisiae response in PKC-SLT2 signaling and glycogen metabolic pathways to antifungal compound calcofluor white

Fungal infection remains a major problem worldwide, yet treatment options are limited owing to the lack of effective drugs, the significant toxicity of available compounds, and the emergence of drug resistance. The low toxicity of calcofluor white （CFW） is an attractive antifungal compound for its known inhibitive effects on trichophyton rubrum and candida albicans growth. However, the efficacy of CFW is limited in most cases. In order to search for effective means to improve its efficacy, using saccharomyces cerevisiae as a model, we have used microarrays to examine the cell＇s response when treated with CFW on the genome scale. We found that both the PKC-SLT2 （i.e, protein kinase C-mitogen activated protein kinase） and the glycogen metabolic pathways are activated upon CFW treatment. These results suggest that the key components in these pathways could be targeted by other drugs to counter the cell＇s compensative response, thus to further substantiate the inhibitive effect of CFW on fungal growth, which may lead to treatment regimens with improved efficacy of this compound in clinical applications.
