Even though lightweight foamed concrete has low mechanical properties compared to normal weight concrete, there is a potential of using this material as partition or load-bearing wall in low-rise residential construction. Before it can be considered for use as a load-bearing element in the building industry, it is necessary to acquire reliable information of its mechanical properties at ambient and high temperatures for quantification of its fire resistance performance. This paper will present the results of experiments that have been carried out to examine and characterize the compressive stress-strain relationship of foamed concrete at high temperatures. Foamed concrete with 650 kg/m3 and 1000 kg/m3 density were cast and tested. The compression tests were carried out at ambient temperature, 100, 200, 300, 400, 500 and 600°C.

Several approaches have been introduced in literature for active noise control (ANC) systems. Since FxLMS algorithm appears to be the best choice as a controller filter, researchers tend to improve performance of ANC systems by enhancing and modifying this algorithm. In this paper, modification is in done the existing FxLMS algorithm that provides a new structure for improving the tracking performance and convergence rate based on the secondary path modeling technique. The convergence rate is improved by the dynamically varying the step size of the error signal. It is also implemented using FPGA.

The thermal power plants are used to generate power. The thermal power plants are designed based on required conditions, but actually inlet conditions are not as per the designed conditions. Variations in the power outputs from power plant are always a matter of disputes. So correction curves for power and heat rate are generated. In this paper, the thermodynamic analysis of 120MW thermal power plant has been done at a different inlet pressure (123.14 bar) and at different inlet temperatures (507.78°C, 517.78°C, 527.78°C, 537.78°C, 547.78°C, 557.78°C, 567.78°C). The correction curves for power and heat rate have been generated for the combined effect of inlet pressure and different inlet temperatures. These curves indicate that if inlet conditions vary then power output and heat rate also vary.

The World cannot exist without Water. It is an important component to human survival. Water should be purified for a better life style. It is the basic duty of every individual to conserve water resources. Nagavati watershed is located in a part of Dharmapuri district of Tamil Nadu in South India. It lies between latitudes 11°45’N to 12°15’ N and 77°30’ E to 78°30 E longitudes. It covers within the Survey of India toposheet nos. 57H/16, 57L/4, 58E/13, and 58I/1 covering an area of about 500 sq.km. Fourty six representative groundwater samples were collected from pre-monsoon season during 2015 and those water samples were analysed by standard analytic methods and physical and chemical parameters such as pH, Electrical Conductivity, Total Dissolved Solids, Alkalinity, Hardness, Na+, K+, Ca2+, Mg2, Cl , HCO3, CO3 , SO4, NO3 and F. Correlation study indicates that different parameters are strongly interrelated. The correlation and regression provide an excellent tool for the prediction of parameter values within a reasonable degree of accuracy.

In the present study numerical analysis of enhancement in heat transfer characteristics in a double pipe heat exchanger is studied using a holed twisted tape. The twisted tape with a constant twist ratio is inserted in a double pipe heat exchanger. Holes of diameter 1mm, 3 mm and 5 mm were drilled at regular pitch throughout the length of the tape. Numerical modeling of a double pipe heat exchanger with the holed twisted tape was constructed considering hot fluid flowing in the inner pipe and cold fluid through the annulus. Simulation was done for varied mass flow rates of hot fluid in the turbulent condition keeping the mass flow rate of cold fluid being constant. Thermal properties like Outlet temperatures, Nusselt number overall heat transfer coefficient, heat transfer rate and pressure drop were determined for all the cases. Results indicated that normal twisted tape without holes performed better than the bare tube. In the tested range of mass flow rates the average Nusselt number and heat transfer rate were increased by 85% and 34% respectively. Performance of Twisted tape with holes was slightly reduced than the normal twisted tape and it deteriorated further for higher values hole diameter. Pressure drop was found to be higher for the holed twisted tape than the normal tape.

Aim: To assess the long-term effects of antioxidants in individuals according to age and sex distribution. Methods: The studied subjects included a total of 150 healthy adults of 96 men and 54 women aged between 30 and 74 years. At the baseline visit, eligible candidate were randomized to either 1 capsule per day of antioxidant nutraceutical or antioxidant functional foods or placebo, and the first dose was dispensed and followed up for six months. Results: The results were grouped based on gender and age ranges, a positive increase in Immunoglobulin M (IgM) and Cytotoxic cluster of differentiation antigen 4 (CD4) counts after antioxidant dietary intervention and higher level of IgM and CD4 in men than in female at some age ranges were observed. Conclusion: The authors suggest the use of antioxidant functional foods as an alternative to antioxidant nutraceuticals in boosting immunity and therefore suggest such for immuno-compromised individuals.

The purpose of this research is to understand and quantify the impact of Building Human Resources on Business-IT Alignment and strength of interaction among them. A theoretical framework is proposed regarding the constructs of Human Resources (BHR), and Business-IT Alignment (BIA) and the construct validity was established. The sample data from 65 firms were obtained through structured questionnaires. Structural equation modeling (SEM) was used to understand the relationships among each of the construct and its attributes. Building Human resources had a strong effect on the Business-IT Alignment , and is statistically significant.

This study investigated the impact of Teacher Trainee Sponsorship Scheme on improving teacher supply in the Bosomtwe-Atwima-Kwanwoma District of the Ashanti Region of Ghana. Questionnaire and interview guide were used to collect data from the District Education Office and the District Assembly. The sample included 228 teachers selected from 45 primary and Junior High Schools. The study revealed that majority of sponsored teachers are native of Bosomtwe-Atwima-Kwanwoma District or share common border with the district. Most sponsored teachers in the deprived areas have some rural background. The scheme is faced with the problem of non-payment of regular and realistic allowances to the teacher trainees. The study revealed that sponsored teachers in the Bosomtwe-Atwima-Kwanwoma District have high expectations for conditions and facilities in the schools and communities. When the conditions and facilities are favourable, the teachers feel satisfied.
