ABSTRACT : Allergic rhinitis (AR) is an IgE-mediated disease that can impact the quality of life and work of affected individuals. Antihistamines were introduced more than 50 years ago for the treatment of AR. They can be classified into three groups. First-generation antihistamines such as promethazine and ketotifen are clinically effective, but they have a considerably limited use by their sedative and anticholinergic effects. Second-generation antihistamines such as cetirizine, loratadine1 and mizolastine have significantly fewer sedative and anticholinergic effects than first-generation. New generation antihistamines include fexofenadine, levocetirizine, desloratadine2 and rupatadine. While many of these agents were largely devoid of CNS (central nervous system) side effects, their tendency for drug-drug interactions (e.g., terfenadine and astemizole) resulted in an increase incidence of cardiotoxicity. Furthermore, some of the second-generation H1 antagonists exhibited weak...

ABSTRACT : In order to precisely control move of underwater robots, the fuzzy PID dual-mode controller based on fuzzy rules switching is invented, combining the conventional fuzzy controller and the more precise PID controller. Fuzzy rules are switched on the basis of different moves of underwater robots. The new controller has been conducted simulation and field experiments on underwater synthetic explored robots. The experiments show that, with pragmatic design and good dynamic performance like traditional controllers, the new controller improves precision while reduces overshoot. It also has good robustness when dealing with uncertainty of the model and external disturbances. On the whole, it has higher pragmatic value.

ABSTRACT : In this study, marine eukaryotic microbial community was analyzed in the context of its complexity and dynamic process in the early stage of biofouling. Samples were collected from five different surfaces: the control group (coating CG), 0.2% Silicium (Coating A), 2% Carbon nanopowder (Coating B), 0.2% Graphite (Coating C) and 2% Silicium plus 2% Carbon nanopowder (Coating F). These coatings were sea-tested for 11 months for their anti-biofouling performance. Coating A and B don’t have anti-biofouling ability just like coating CG, while coating C and F have excellent anti-biofouling capacity. Single stranded conformation polymorphisms (SSCP) was employed to analyze diversity level and dynamic changes of marine fouling eukaryotic communities adhering to different coatings during different sampling time (day 2, 4, 6, 9 and 14). The results indicated that composition, distribution and diversity level of marine fouling eukaryotic microbial community presented obviously di...

ABSTRACT : The effect of antimony (Sb) addition in SeIn glassy system is theoretically studied, and important physical properties, such as average coordination number, lone pair electrons, fragility parameter, heat of atomization, mean bond energy and optical band gap are evaluated in addition to thermal stability. The values of average coordination number and heat of atomization were found to increase with increasing Sb content, while the other properties were in decrease. By adding more Sb atoms, the glassy system becomes less stable thermally. According to the number of zero-frequency mode per atom, which was in decrease, the Phillips’-Thorpe threshold cannot be realized for the considered glassy system.

ABSTRACT: Selective molecularly imprinted polymers (MIPs) for solid-phase extraction and determination of glipizide have been designed and prepared. MIPs were synthesized with acrylamide as the functional monomer and ethyleneglycoldimethacrylate as the cross-linker in chloroform as a porogenic solvent by using bulk polymerization method. MIPs are able to bind 100% glipizide in chloroform by using a batch method compared to a non-imprinted one. By using Fourier Transform Infra Red, it was found that hydrogen bonding occurred between the carbonyl group of acrylamide and the proton donor of template. These results find the opportunity for this MIP to be used as an alternative of the pretreatment method before determination of glipizide by using glibenclamide as a pseudotemplate.

ABSTRACT: In microbiologically influenced corrosion (MIC) study, the electron acceptor of the cathode plays a decisive influence on corrosion characteristics. Some bacteria which can directly absorb electrons releasing from the anode reaction of the microbial dissolution of iron have been found in anaerobic biofilm studies, including some of the sulfate-reducing bacteria (SRB), methanogens and some other corrosion-reducing bacteria. These bacteria in biofilm are showing severe corrosion because of their different electron transfer mechanism. The corrosion mechanisms of these corrosion bacteria is called electron microbial influenced corrosion(EMIC), EMIC and its electronic transfer mechanisms distinct from those chemical microbial influenced corrosion(CMIC) mechanism bacteria that indirectly effects on the anode and cathode electrode reaction from nature. In recent years, EMIC mechanism has become a hot topic in the field of microbial corrosion. This paper describes the microbial ...

ABSTRACT : Adsorption is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or, more rarely, a liquid (adsorbent), forming a molecular or atomic film (the adsorbate). Exchange adsorption, Physical adsorption and chemical adsorption have been recognized as adsorption types. This study involves the separation of an azeotropic mixture (benzene-cyclohexane) by adsorption technique using Eu-GAC(Granular Activated Carbon) and Sand. The Eu-GAC was produced by thermal pyrolysis of Eucalyptus tree branches and leaves and the Sand was collected from El-Khums seaside. The influence of several parameters such as dose or mass of adsorbent, pH, mesh number and contact time were investigated. The optimum adsorption efficiency occurred at pH 3. The optimum contact time for both adsorbents was found to be 3 hours. The adsorption of azeotropic mixture (benzenecyclohexane) improved by increasing adsorbent dose and mesh number (Mesh No 100). This study has concl...

ABSTRACT : The ultra-weak luminescence (UWL) feature of plant seeds is investigated. Before UWL measurement, the maize seeds are moistened in distilled water for various periods, which are 2h, 4h, 6h and 8h. And then the seeds are dried to the mass they had before moistened. The UWL measurements are made before and after distilled water injects into measured samples. A kind of double exponential function is proved fitting the tested data well as the coefficient of determination of fitting is above 0.97. It is observed that UWL properties of different samples have obvious regularities. The dry seeds contain a large number of hydrophilic pores, so water quickly permeates into maize seeds and forces the seeds to produce stress UWL after water injection. The intensity of UWL depends on the structure of seeds and the time of moistening. Over a period of time, the different UWL intensity of samples decays to the same level as the seeds without moistening. The study results contribute ...
