Accelerated engineering properties of high and low volume fly ash concretes reinforced with glued steel fibers

Vallarasu Manoharan SOUNTHARARAJAN, Dr. Anandan SIVAKUMAR

《结构与土木工程前沿(英文)》 2013年 第7卷 第4期   页码 429-445 doi: 10.1007/s11709-013-0226-6

摘要: The present study focuses on the improvement of pozzolanic reaction of fly ash particles with the cement hydration products. Low and high volume fly ash concrete mixtures were studied systematically with the addition of accelerating admixtures and accelerated curing of the concrete specimens in a steam chamber for 18 h at 75°C. Also, the reinforcing effects of glued steel fibers addition on the compressive and flexural performance of fly ash concrete were investigated. The test results indicated that the addition of accelerator improved the rate of hardening and the inclusion of steel fibers provided higher flexural performance. Also, it can be noted that the high volume fly ash (50%) addition in concrete showed a reduction in strength; however, the addition of accelerator has compensated the deceleration in strength gain. The proper selection of concrete ingredients, addition of accelerator and initial steam curing for 18 h showed better improvement on the engineering properties in fly ash concrete. A maximum increase (41.7%) in compressive strength of fly ash concrete around 52.90 MPa was noticed for 25% fly ash substitution and 1.5% steel fibers addition. Dynamic elastic modulus was also calculated in loaded concrete specimen using ultrasonic pulse velocity test and showed a good agreement with the experimental value.

摘要:

Pneumonic plague that originated in Russian Siberia broke out in Northeast China in October 1910–March 1911. On the basis of field visits, autopsy, bacteriological identification, and close collaboration with local authorities and international colleagues, Dr. Wu Lien-Teh implemented a series of efficient antiplague measures, which successfully controlled the development of an extraordinary epidemic plague. In his subsequent work, Dr. Wu demonstrated the respiratory transmission of pneumonic plague and tarbagans’ role in this spread. Dr. Wu’s academic and cultural contributions are valuable in the medical progress in China.

Smart residential energy management system for demand response in buildings with energy storage devices

S. L. ARUN, M. P. SELVAN

摘要: In the present scenario, the utilities are focusing on smart grid technologies to achieve reliable and profitable grid operation. Demand side management (DSM) is one of such smart grid technologies which motivate end users to actively participate in the electricity market by providing incentives. Consumers are expected to respond (demand response (DR)) in various ways to attain these benefits. Nowadays, residential consumers are interested in energy storage devices such as battery to reduce power consumption from the utility during peak intervals. In this paper, the use of a smart residential energy management system (SREMS) is demonstrated at the consumer premise to reduce the total electricity bill by optimally time scheduling the operation of household appliances. Further, the SREMS effectively utilizes the battery by scheduling the mode of operation of the battery (charging/floating/discharging) and the amount of power exchange from the battery while considering the variations in consumer demand and utility parameters such as electricity price and consumer consumption limit (CCL). The SREMS framework is implemented in Matlab and the case study results show significant yields for the end user.

摘要: An oxetane-derived monomer, 3-acryloyloxymethyl-3′-methyloxetane (AMO) was prepared from the reaction of 3-hydromethyl-3-methyloxetane with acryloyl chloride. The cationic ring-opening copolymerization of AMO with another oxetane-derived monomer, 3-(2-(2-(2-methoxyethylenoxy)ethylenoxy)ethylenoxy)-3′-methyloxetane (MEMO) was conducted in CHCl solution using BF3 ·OEt/1, 4-butanediol as a co-initiator. The resulting copolymers were characterized by FTIR, H NMR and Gel Permeation Chromatography (GPC) analyses, and it was found that the enchained ratio of AMO in the copolymers is far lower than its feed ratio. They were crosslinked via the radical polymerization of the vinyl group initiated by BPO after doping with lithium trifluoromethanesulfonimide (LiTFSI) to give rise to tough polymeric electrolyte films. The ionic conductivity was measured at varying content of AMO and different concentration of lithium salt LiTFSI by AC impedance, and a maximum ion conductivity of 1.44×10 S/cm at 30°C or 1.25×10 S/cm at 80°C was attained in the sample PAM 33 at the mole ratio of O : Li = 20. The DSC results indicated that decreases with the increase of the proportion of AMO in the copolymer, well consistent with the ion conductivity trend. The TGA (thermogravimetric analysis) measurement revealed that this kind of copolymer electrolytes is more thermostable than their liquid counterparts.

摘要: Schistosomiasis japonica, a zoonosis caused by , is endemic to the Philippines and China. Several vaccine candidates have been identified and tested in different animal models, but it is still unclear which will be optimal for testing in the field. Therefore, new antigens and strategies are necessary for vaccine development against schistosomiasis japonica. The Sj14-3-3 gene was amplified and subcloned into the expression vector pPICZ?-B and transformed into X-33 by electroporation. Three transformants were induced with methanol. The cultural supernatant was collected and tested by SDS-PAGE and Western blotting. The protein of rSj14-3-3 was prepared and purified and BALB/c mice were immunized which was followed by a challenging infection. The immuno-protection was then evaluated. The Sj14-3-3 gene was expressed and secreted into the medium and its molecular weight was about 35000 as determined by SDS-PAGE. Western blotting showed that the protein had a high specificity against mouse-anti-Sj14-3-3 monoclonal antibody and rSj14-3-3 had a promising immune reactivity. The results of the immuno-protective experiments revealed that the worm reduction was 26.0%, 32.2%, and 36.8%, respectively. The number of eggs in liver tissue was reduced by 36.8%, 43.2%, and 46.1%, respectively. The recombinant Sj14-3-3 of eukaryotic expression in was successfully harvested. The molecular vaccine of Sj14-3-3 could partially induce resistance to the infection with in BALB/c mice. The recombinant protein Sj14-3-3 has promising immunological potentials for further approach to the diagnosis and development of molecular vaccine.

作为免疫疗法靶点的FOXP3及其辅因子 Review

摘要:

叉头框蛋白P3(FOXP3)是调节性T细胞(Tregs)的一个主要调节因子,调节性T细胞是能抑制抗原特异性免疫反应的T 细胞亚群,在增强宿主耐受性和维持免疫平衡方面发挥着重要作用。众所周知,FOXP3 与多种蛋白质形成复合物,并能通过乙酰化、磷酸化、泛素化和甲基化等各种翻译后修饰(PTM)进行调节。因此,翻译后修饰可改变FOXP3 的稳定性及其调节基因表达的能力,并最终影响调节性T细胞活性。虽然FOXP3 自身并非理想的药物靶点,但脱乙酰酶、乙酰转移酶、激酶和其他可调节FOXP3 的翻译后修饰的酶均为调控FOXP3 和调节性T细胞活性的潜在靶点。但FOXP3 并非这些酶的唯一底物;因此,当使用相关抑制剂时,必须考虑是否存在有害的“FOXP3脱靶”副作用。
