ABSTRACT : The freeze-thaw failure of concrete in many researches is described by dynamic elastic modulus, which is not applicable to estimating the loss of concrete strength in structural engineering. To avoid the deficiency, the paper attempts to establish an applicable failure surface in principal stress space for concrete to describe concrete strength change under different freeze-thaw cycles. Based on the discussion of meson-state of concrete under freeze-thaw cycles, hypothesis about concrete failure surface under freeze-thaw cycles is brought forward. Then, the damage of concrete and build up evolution equations is presented. Finally, a concrete failure surface model is given to predict concrete strength under different freeze-thaw cycles. Compared with available test data, the validity of new model is proven.

ABSTRACT : The rates of oxidation of adenine and chlorogenic acid by tert-butoxyl radicals have been studied by measuring the absorbance of adenine at 260 nm and chlorogenic acid at 328 nm spectrophotometrically. tert-butoxyl radicals are generated by the photolysis of tert-butyl hydroperoxide in presence of tert-butyl alcohol to scavenge •OH radicals. The rates and the quantum yields (φ) of oxidation of chlorogenic acid by t-BuO• radicals have been determined in the absence and presence of varying concentrations of adenine. An increase in the concentration of adenine has been found to decrease the rate of oxidation of chlorogenic acid suggesting that adenine and chlorogenic acid compete for t-BuO• radicals. From competition kinetics, the rate constant of chlorogenic acid reaction with adenine has been calculated to be 4.43 x 108 dm3 mol-1 s -1. The quantum yields (φexpt) have been calculated from the experimentally determined rates of oxidation of chlorogenic acid under differe...

ABSTRACT : Shift-in power is one of the main elements of the test dynamic power for integrated circuits testing. The paper proposes a low power test scheme for broadcast scan architecture to reduce shift-in dissipation. Unlike conventional broadcast scan, the proposed scheme divides multiple scan chains into several scan chain segments, and only the first internal scan chain is fed directly by the scan Input SI, and used as the path of shifting test data for all the scan chain segments. Thus, only one scan chain is activated when test data shifting in, the test data shift-in power could be reduced effectively. To further reduce test shift-in power, the scan cell reordering which put the similar scan cells in adjacent positions for each two adjacent segments are also used in this paper. The theoretical and the experimental results illustrate that the proposed scheme could reduce dynamic power dissipation during scan testing significantly. Further details @ http://www.joc...

ABSTRACT : A lipolytic fungus named Yz15 which produced extracellular lipase was isolated from the water and soil samples contaminated with oil. The 18S rRNA sequencing revealed it as a novel strain of Aspergillus niger. Lipases was particularly important due to the fact that they were used for different industrial processing. So in this study we carried out optimization of lipase production from Aspergillus niger Yz15 using statistical designs. The important factors influencing the lipase activity were identified by initial screening method of Plackett-Burman experimental design, which showed that olive oil, magnesium sulfate and initial pH were the significant variables (P<0.05).

ABSTRACT : The oxidative cleavage of diethylene glycol by bromate ion has been studied in hydrochloric acid medium in the temperature range 298-313 K. The rate of the reaction is dependent on the first power of the concentration of diethylene glycol and bromate ion. The reaction rate increases with increase in H+ concentration in the range (0.1 - 1.0) mol dm-3 and reaction is first order with respect to [H+ ]. The reaction has been shown to occur with the formation of an unstable bromate ester which decomposes to the reaction product in one step two-electron transfer process. Formaldehyde has been identified as the oxidation product of diethylene glycol. The activation parameters of the oxidative cleavage of diethylene glycol have been evaluated.

ABSTRACT : Dyeing wastewater has caused serious synthetic dyes pollution on both water bodies and soil in China. This study investigated the mechanism of azo dye removal by different vegetative organs of hydroponically grown sunflowers. In all treatments, the percent of dye removal by living organs was higher than corresponding dead organs. The results show that decolorization of Evans blue by tissues of sunflowers was partly attribute to degradation and partly due to sorption. Moreover, the biodegradtion played a greater role than sorption in the dye removal. The biodegradation rate of the dye was estimated. Realistic values of Km and Vmax were estimated by a computer program using non-linear regression treatment and Lineweaver–Burk model. In both methods, the rate of azo dye removal from the aqueous solution by roots was the highest, followed by leaves and stems.

ABSTRACT : The solubility of the drug substances in water is one of the major factors taken into account in the formulation of oral solutions and parenteral dosage forms. The present study was conducted to improve the solubility of acetaminophen in water by the use of phospholipids and nonionic surfactants (Tween® 80 and Solutol® 15HS). These excipients are well tolerated by the parenteral route and allow the solubilization through a micellar system. In our study, a design of experiments approach was tested using a mixture design of nonionic surfactants, phospholipids and acetaminophen. The results showed a significant increase in the solubility in all used mixtures. The analysis of the design space showed that the solubility of acetaminophen varies very closely with the concentration of the three surfactants in water and also with their association.

ABSTRACT : All the strains screened out from contaminated soils were capable of degrading diesel oil while consortium and strains Q18 had stronger degradation efficiency. It’s found that the existence of alfalfa and mustard could promote the degradation of diesel oil significantly. The existence of plant and the growth of roots may have changed the soil environment to make it more suitable for the growth of strains and degradation. In addition, the number of strains in the mustard rhizosphere was larger than that in the alfalfa rhizosphere, which showed that mustard had stronger ability on the activation of strain. This may be related to the different growth characteristics of mustard and alfalfa. In the experiment, Rhodococcus Q18-Indian mustard complex had the highest rate of degradation of diesel oil.

Four new different complexes were prepared and formulated as [Ni2(salen)(CH3CO2)2(AAP)2] (1), [Ni2(salen)(CH3CO2)2(PDCH)2]·2H2O (2), [Cu2(salen)(CH3CO2)2]·2H2O (3) and [Co(salen)(CH3CO2)]·(H2O) (4). The H2salen ligand and its complexes were characterized by IR, UV-visible, TG, elemental analyses, and molar conductivities. The complexes were proposed to be distorted octahedral geometry with Ni(II) and Co(III) and distorted square planar geometry with Cu(II). Antibacterial activity of the complexes was tested against selected bacteria by agar well diffusion method.

ABSTRACT: Security assessment with vulnerability is based on American Petroleum Institute (API) Standard 780 Security Risk Assessment (SRA) Methodology which gives fixed steps combining with vulnerability, As Low As Reasonably Practicable, Swiss Cheese Model and cost-effectiveness theory. Vulnerability of different periods were analyzed emphatically, such as vulnerability before accidents, vulnerability in accidents and vulnerability after accidents. As Low As Reasonably Practicable can allow managers to know clearly that which assets should be protected deeply. Swiss Cheese Model helps analyzers understand detailed reasons of attacks and avoid adversaries’ attacks. Through cost-effectiveness theory, benefits of the security investments can be maximized. Overall, this article can make managers know more about the risk level in multiple dimensions and enlighten analyzers to assess the risk level of chemical plants.

ABSTRACT: In recent years the increased incidence of candidal infection is observed in the world, among them candidiasis takes the leading place. Candidiasis is an infectious disease caused by yeast-like fungi of Candida genus. There are both mild forms of this disease – candidiasis of the skin and mucous membranes and very severe forms – generalized candidiasis of visceral organs. In order to fight candidiasis the authors have developed an immunobiological drug for prevention and treatment of candidal infection. The drug contains antigens of C. albicans and C. tropicalis fungi with the total protein concentration of 4 mg/ml. The composition of the drug also includes the solvent phosphate buffer solution with рН 7.2 ± 0.2 and the preservative phenol in the conce ntration of 0.25 %. The drug developed possesses the protective and therapeutic effect. The aim of this work was to study toxicity of the immunobiological drug. The abnormal toxicity of the solution of the immunobiologic...

ABSTRACT: The P-sets ( ) F F A , A is introduced to study the dynamic characteristics of the set better. The packet sets ( ) F F A , A is a collection of sets which is composed of the internal packet set F X and the outer packet set F X ; in this paper, we not only introduce the attribute value matrices in the finite case, but also illustrate the relationship between the attribute value matrices and the packet sets. Finally we give the algorithm and examples using the attribute value matrices for the P-sets.

ABSTRACT: Cinnamon oil has been confirmed as a useful antifungal agent to inhibit Rhizopus nigricans. However, the antifungal mechanism has not been clearly revealed. The possible mechanism as follows were investigated, such as the effects of cinnamon oil on the cell morphology, cell membrane and the activities of the key enzymes in tricarboxylic acid (TCA) cycle. Cinnamon oil can inhibit the mycelia growth of R. nigricans, and scanning electron microscope (SEM) observations revealed that the mycelia morphology alterations of R. nigricans were the markedly shriveled and collapsed hypha, even flatted empty hyphae, swelled cell wall, disrupted plasma membrane, with cytoplasmic matrix leakage. Furthermore, cinnamon oil inhibited the biosynthesis of ergosterol significantly, damaging the cell membrane structure, causing the leakage of intracellular ions, protein and the higher absorbance at 260nm. Moreover, cinnamon oil affected the energy metabolism of R. nigricans by decreasing th...
