Paper Topic: Performance and emission studies of a SI engine using ethanol-butanol-acetone and gasoline blends

Abstract: Use of conventional fuels in gasoline engines result energy crisis and environmental pollution. These has necessitated the search for alternative fuels. Ethyl alcohol is one of the promising fuels than can substitute gasoline in SI engine. The present work investigates the effect of using acetone-butanol-ethanol and gasoline blends in a spark ignition. The experiments were conducted on a multi cylinder MPFI spark ignition engine connected to hydraulic dynamometer. The fuel blends were prepared by mixing ethanol-butanol- acetone and gasoline in the ratio 5:5:2:88 by percentage (B1) and 10:5:2:83 by percentage (B2). The speed of the engine was varied from 1500 to 3000 rpm in steps of 500 rpm by keeping load constant at 6 kg. Performance and emission parameters were measured and baseline gasoline data. It is observed that a slight reduction in brake thermal efficiency was observed for increase in ethanol percentage fuel operation. Emission parameters like CO and HC were drastically reduced with increase in CO2 emission. However NOx emission was found to be higher for ethanol blended fuels.

Keywords: brake thermal efficiency; butanol; emissions; ethanol; gasoline.

Paper Topic: Truncations in α-mating factor secretion signal to enhance the secretory efficiency of granulocyte colony-stimulating factor in Pichia pastoris

Abstract: The methylotrophic yeast, Pichia pastoris, has been used effectively as a host for production of bioactive granulocyte colony-stimulating factor (G-CSF) under Saccharomyces cerevisiae derived α-mating factor (MATα) under the control of the Alcohol Oxidase 1 promoter. A maximum of 75 mg/L of the product was detected in the extracellular medium. In the present study, strategy involving truncations in the pro-region of the leader peptide was adopted to boost extracellular levels of G-CSF. Deletion in amino acid residues (MATα:D57-70, MATα:D30-43, MATα:D47-49) and their combinations (MATα:D57-70,30-43 and MATα:D57-70,47-49) were carried out by site-directed mutagenesis. All mutants were evaluated for growth and extracellular protein production. It was found that out of a number of deletions, MATα:D57-70 showed a 5-fold increase in G-CSF secretion, and, about 1.5-fold increase in total extracellular protein levels, as compared to the wild-type construct. The molecular modeling of the mutant α-mating factor signal peptide was carried out and the results indicated that the distortion in the secondary structure favored greater flexibility of the pro-peptide to freely interact with the cargo protein, thereby promoting elevated levels of G-CSF. The present findings raises the possibility to alter these sequences for expression of other heterologous proteins in the P. pastoris system.

Keywords: Pichia pastoris; G-CSF production; Site-directed mutagenesis; α-Mating factor

Paper Title: Effect of Te additive on thermal stability and glass forming tendency of Ge-Sn-Se chalcogenide glass system

Abstract: Thermal characterization of Ge20Sn10Se70-xTex (x = 0, 3, 6, 9, 12, 15) glass system has been undertaken in the present research work. Dependence of glass transition temperature and thermal stability on glass composition has been established via DSC technique. Fundamental kinetic parameters viz. glass transition temperature Tg, Hruby parameter Hr, crystallization temperature Tc etc., have been experimentally calculated under non isothermal conditions at the constant heating rate of 100C. DSC traces shows higher difference between crystallization temperature Tc and glass transition temperature Tg which suggests the greater glass forming tendency and resistance towards crystallization. Glasses under study shows good thermal stability, hence, can find practical applications especially in phase change optical memory

Keywords: Chalcogenide glasses, thermal properties, Differential scanning calorimetric technique, thermal stability, glass forming tendency.

Paper Title: Comparison of environmental costs and performance in the processing of sorted waste on model

Abstract: The aim of this paper is to analyze the additional environmental load caused by the treatment of sorted waste for the selected type of waste using the model. On the basis of the comparison with the positive effects of recycling, the total net environmental effect from the recycling of the selected type of waste is determined. Modelled is part of the LCA chain for the processing of plastic waste in the conditions of the Czech Republic. The analysis includes all identified input and output material and energy flows according to company records. Model takes into account the environmental burden of consumed energy and of auxiliary materials necessary for plastic waste recycling process. The model is processed using a colored Petri net. Modeling results serve to compare the environmental burden and the overall environmental recycling effect.

Keywords: Plastic waste recycling, material and energy flow management, modeling, Petri nets, sustainability

Paper Title: Design and Development of Fatigue Testing Machine For Cryogenic Temperatures

Abstract: Prior knowledge of fatigue strength properties of materials is very crucial in designing and developing a mechanical system failing which premature collapse of the entire system can take place. Reliable data of these properties are not available at cryogenic temperatures. Room temperature data cannot be extrapolated down to cryogenic temperature zone. With this background, a rotating beam fatigue testing machine suitable for both room and cryogenic temperatures has been designed and developed to determine fatigue properties of various materials commonly used for cryogenic temperature applications. The tests are conducted within an insulated cryogenic chamber. Desired cryogenic temperatures down to 77K are maintained by circulation of pressurised liquid nitrogen with the help a solenoid valve which is activated by a PID controller. Tests are conducted on selected grades of steels (SS304), aluminium (2024 and 7075) and titanium alloys. Test results are studied and compared with room temperature properties and analysed.

Keywords: Cryogenics, Liquid nitrogen, Fatigue strength, Cantilever and Cryogenic chamber

Paper Title: Design and Development of Fatigue Testing Machine For Cryogenic Temperatures

Abstract: One of the most important scientific research activities in both of energy and environmental sectors, is synthesizing of composites such as nanocatalyst powders of zinc oxide and titanium oxide. Due to their optical,electric properties,low cost,stability, nontoxicity, and ease of availability, they have been proven to be promising photocatalysts. Owing to the extension of light absorption range and effective charge transfer from ZnO to TiO2 their composite has a superior photocatalytic activity. The purpose of this investigation is to study the applicability of ZnO–TiO2 composite as a photocatalyst for degradation of Bentazon in polluted water. Effects of many various parameters will be studied, such as catalyst dosage, pH, initial Bentazon concentration, purging of oxygen gas, hydrogen peroxide concentration and total organic compounds on the removal efficiency of Bentazon.The greatest removal of Bentazon is at neutral pH due to photo-corrosion of ZnO composite in acidic and basic conditions. While it is decreased in the presence of organic compounds. Removal efficiency of Bentazon by UV/ZnO/TiO2 process is greater than that by UV/TiO2 process, UV/ZnO, and UV alone.

Paper Title: PM2.5 Compositions and Health Risk Estimation Towards Primary School Children in Kuala Lumpur

Abstract: Indoor air pollution in school building play an important role since children spend about 90% of their time in the classrooms. The study aims to measure the composition of PM2.5, which were the trace metals and ionic species in air samples and evaluate the carcinogenic and non-carcinogenic health risk among school children. Air samples were simultaneously collected for indoors and outdoors in 19 primary schools by using Low Volume Sampler (LVS) for 24 h from May to November 2017. Trace metals and ionic species were quantified by using inductively couple plasma-mass spectrometry and ion chromatography, respectively. The average PM2.5 indoor concentrations was 42.96±21.47 µg/m3 and 37.08±18.74 µg/m3 for outdoor with indoor to outdoor ratio (I/O) value was greater than 1. The higher concentration of PM2.5 in indoor as compared to outdoor suggested that the physical activities of students affected the indoor air quality (IAQ). The trace metals concentration followed the order of Al>Fe>Zn>Sr>Ni>Pb>Cr>Mn>Cu>Co>Cd for indoor and Al>Fe>Cu>Zn>Sr>Ni>Pb>Cr>Mn>Co>Cd for outdoor. Ionic species concentrations showed the same order for indoor and outdoor, Ca2+>K+>NH4+>SO42->NO3->Cl->Mg. The potential inhalation risk estimations for trace elements in PM2.5 show that the hazard quotient (HQ) was higher than acceptable value of 1 and excess lifetime carcinogenic risk (ELCR) values are within the acceptable range (10-6 to 10-4). This study suggests that there is possibility of non-carcinogenic health risks towards school children.

Keywords: PM2.5, indoor air pollution, health risk assessment, trace metals, ionic species

Paper Title: High-Tc Superconductivity (HTSC): Influence of Next-Nearest-Neighbor (NNN) Hopping and Exchange Interactions

Abstract: The t - t' - J - J' model, one of the realistic extensions of the t-J model to understand the characteristics of the high-Tc cuprates, has been investigated to explore hole pairing, s- or d-wave pairing mode of holes and some of the ground state properties using exact diagonalization (ED) method within an 8-site tilted square cluster. The role of the next-nearest-neighbor (NNN) antiferromagnetic exchange interaction and NNN hopping interaction has been considered. An s-wave superconducting phase is established. 2-hole binding energy calculation indicates that stable bound pair of holes is formed in the region J´/t > 0.15. 4-hole binding energy clearly shows that superconducting condensation is not possible in the system. Charge gap shows a gapped behavior which decreases with NNN hopping and large J´/t. Spin gap curves establish a gapless behavior at small t´/t and J´/t. Also, it appears that effective exchange interaction is very much relevant in the present system.
