Abstract: Recently, protein-antibody therapeutics becomes a hot search topic. In this paper, all protein interaction data files are collected from INTERPARE. Protein sequence and its secondary structure both are used to build HMM mathematical model. We randomly take 80% data to train positive and negative HMM models and 20% data to test. The accuracy of this approach can reach to 79.80%. This model can further be used to predict protein function sites and predict if a protein interacts with other proteins.

Abstract: Constructed a two-chambered microbial fuel cell (MFC) and a similar abiotic fuel Cell----Steel fuel cell (SFC), studies the influence of elimination effect about various variables (anode material , size of salt bridge and so on) to the nitrate. The experiment indicated that the elimination efficiency of MFC to the nitrate is 71.46% equally, SFC is 67.99%, and degeneration speed of nitrate is 8mg nitrate/L/day approximately. It has confirmed that MFC and SFC is one highly effective method on elimination nitrate, and the elimination effect of MFC to nitrate is better than SFC.

Abstract: Worldwide changes in climate and environment forced us human beings to seek for alternatives to replace commercial energy products like coal and petroleum. However, there have some difficulties to promote commercial energy products in China’s rural areas and newly urbanized areas. Biomass combustion system will become one of the ideal devices for such areas in a period of time. It is necessary to develop new types of biomass combustion system consisting of gasification or Semi-Gasification and combustion units so that it can provide high efficiency and low cost for household purposes.

Abstract: The composting with chicken manure as raw material was carried out to study the effects of indigenous and exogenous inoculation on temperature, oxygen concentration, as well as protease activity, urease activity, dehydrogenase activity and cellulase activity in different composting stages by using a composting bioreactor. The treatment with indigenous microbial inocula had higher temperature and lower oxygen concentration at the beginning stage of composting. During the period of raising temperature, the protease activity, urease activity and temperature were highly significant positive correlation (p <0.01); At the period of raising temperature and High-Temperature, dehydrogenase activity and temperature were all highly significant positive correlation between (p <0.01); There was a significant positive correlation between the temperature and cellulase activity at the High-Temperature period (p <0.05) . Endogenous microbial inocula was favor of protein and urease activity increased rapidly, and the promoted the quick start of composting during the temperature raising; At the High-Temperature stage, cellulase and dehydrogenase activity were advanced after inoculated indigenous microbial inocula, promoted oxidation-reduction reaction during the composting.

Abstract: Final volatiles yield of biomass devolatization at flash heating rate was determined via experiments. Samples of wheat straw and corn stalk powder were dispersed in the feeder and were carried by argon into the laminar entrained flow reactor. Flash devolatization of tiny biomass particles was accomplished in the moderate temperature reactor. Residue was collected and the ash content of it was detected in a thermo-grametric analyzer. Final volatiles yield was calculated using ash trace method. Altogether, 96 experiments (including repeat ones) of different reaction temperature (500, 550, 600, 650 °C), different collecting distance (550, 600, 650, 700 mm away from inlet). Results showed that final volatiles yields of wheat straw and corn stalk are 79%, 85 % separately. High reproducibility of the experiments showed it is a reliable method to determine final volatiles yield of biomass devolatization at flash heating rate. Kinetic parameters for wheat straw and corn stalk were modified as A=1009/s, E=3782kJ/mol and A=596/s, E=3716kJ/mol, respectively.

Abstract: The content of assimilable organic carbon (AOC) has been proposed to control the growth of heterotrophic microbe in drinking water distribution systme. However, recent results have shown that there are regions where it is predominantly phosphorus which determines the extent of microbial growth in drinking water. The growth of bacteria was studied in a drinking water distribution system where the content of AOC was high (40.84- 551.35 μg acetate-C/L) and the content of Microbially Available Phosphorus (MAP) was also high (0.69-8.01 μg PO₄^3--P/L). It was AOC other than phosphorus that controlled the growth of bacteria in the drinking water distribution system. Comparably obvious linear relationship was found between the maximum HPC and the maximum content of AOC of the distribution system. Removal of organic matters is ideal approach to control water quality of the drinking water distribution system.

Abstract: Bagasse ash is one of the agricultural wastes and valuable biomass by-products in sugar milling. It was treated hydrothermally with hydrochloric aqueous solution at 100 °C and burned at 600°C for 2 hours under oxygen feeding. The obtained white ash was further used as natural silica source instead of silica sol because of highly silica content from an abundant supply of sugar industries in Thailand. Aluminosilicate precursor gel was prepared from alumina source and silica source via sodium silicate preparation. Different crystallization time was studied for the molar ratio of SiO₂/Al₂O₃ = 2 at 100°C crystallization temperature. The phillipsite zeolite synthesized was characterized using various techniques; X-ray diffraction, Scanning electron microscopy, Fourier Transform Infrared Spectroscopy, and BET-N2 adsorption method. The results can be used as value added for bagasse ash utilization, minimize the environmental impact of disposal problems and further application for heavy metal removal.

Abstract: Clinical Practice guidelines strongly relies on evidence based medical literature. In Health care domain decision support systems are playing a competent role in diagnosis and treatment from multiple diseases. Among different Hospitals all over the world the Information technology domain emphasis key roles in improvement of patient health care to great extent. The Concept of Data Mining (DM) and Decision Support systems (DSS) in medical domain provides an efficient mechanism to extract the multiple records of patient treatment diagnostics from previously stored records in Data base (DB) or Data Ware House (DWH) and compare these guidelines to perform strong analysis that results in efficient decision making. Along the previously mentioned techniques the era of Telemedicine has also being developed that results in generation of multiple techniques in diagnosis of multiple diseases and health improvement using Mobile Health care systems specially worth full for the rural areas where latest medical facilities are unavailable at the point of need. The required information in Database or in Data Ware House might be the historical data of patient or the health based summery of different patients in diverse stages. Now these days the emergence of distributed decision support systems in health care domain covers the health care treatment procedures in more comprehensive manner including surgical procedures and radiological treatment. In this paper we are going to analyze the multiple health care diagnosis procedures and treatment techniques using various decision support systems designed and implemented by various researchers all over the world and compare the effectiveness and efficiency of each decision support system in health care domain. Our research study is also helpful for physicians and health care practioners in analyzing multiple scenarios related to interesting pattern recognitions and intelligent decision making.

Abstract: Modern welding proceedings can be a beneficial method for repairing marginal adaptation defects in fixed prostheses technology. The aim of the study was to conduct experimental investigations to determine the optimal microplasma welding parameters according to the defect type. Different Ni-Cr alloy cast metal restorations with marginal defects were selected and divided depending on the repair possibility. A microplasma welding device, Welder, was used and as filling material a specific Ni-Cr wire was chosen. The process parameters were determined for each case. Introducing the practice of welding in dental technology requires prior experiments to determine the process parameters for the individual processes and their reproducibility.

Abstract: It is essential for a weld to satisfy the requirements of certain standards in the field where it is applied. The aim of the study was to highlight the discontinuities which can appear in the joints achieved by laser and microplasma welding of base metal dental alloys used in fixed prosthodontics. All types of discontinuities which are visible from visual inspection were searched: inclusions, inadequate joint penetration, incomplete fusion, undercuts, overlaps, underfills. Recognizing the defects and discontinuities and their delimitation was essential in determining the weld quality. The obtained results were satisfactory for the purpose both for microplasma and laser welding. Using these methods, welds without defects, which meet minimum acceptable standards for each case, could be obtained.
