Spices show potential health benefits, as they possess antioxidant activity. Ginger and turmeric are major spices used in Indian cooking. Effects of cooking processes on the levels of antioxidants in ginger and turmeric extracts were studied. Water and acetone extracts of raw, boiled and roasted ginger and turmeric were analyzed using FRAP assay. In the case of ginger, antioxidant activity was found to be lower in extracts prepared after boiling and higher after roasting. The antioxidant activities in turmeric extracts prepared after boiling as well as roasting were higher.

Climatic responsive buildings are examples of a sensitive approach to energy consciousness for indoor comfort conditions. It has now become essential to develop energy efficient building design. The basis requirement of a building is to provide thermal comfort to its occupants. In modern buildings this is usually accomplished with the help of mechanical cooling or heating. With the advent of energy crisis there has been a need to develop climatic design tools which will provide thermal comfort in a building without or with minimum expenditure of energy. Climate determines the amount of solar radiation and mean outside temperature that a building is exposed to. Buildings are experiencing overheating during summer. For a built form, vertical surfaces are the most critical to the impact of solar radiation. This study examines the effect of different plan forms on the total solar radiation received by vertical surfaces of the buildings. The aim of this paper is to analyse the climatic conditions with respect to thermal comfort in buildings for the location of Bhubaneswar. The impact of building location and orientation on thermal comfort has been investigated. Different building shapes (square and rectangular) have been studied with variations in width-to-length ratio (aspect ratio) and building orientation. This study guides designers on choosing optimum form and appropriate orientation for buildings. The present paper describes how different plan forms are affected by solar radiation. Based on that the optimum aspect ratio (Length: Width) of the building over the location of Bhubaneswar has been found out which will receive minimum radiation in summer and maximum radiation in winter. This result in significant saving in the energy consumed while creating comfortable indoor environment.

Entrepreneurs in many small firms could not specialize in one specific functional area but are required to operate across the range of management competencies. Different strategies, techniques, styles of leadership have been evolved to manage people effectively. Leaders of the organization have to understand the logic behind this ideology and accordingly nurture Entrepreneurial Managerial behavior among their employees. This research finds out that there is perfect positive relationship between Transformational leadership and Entrepreneurial Managerial Behavior.

To evaluate the effectiveness of modulated frequency transcutaneous electrical nerve stimulation (TENS) on relieving pain after abdominal surgery. The study population was those who underwent abdominal surgery. The subjects were randomly divided into two groups (treated with frequency modulated TENS and placebo TENS). Both the groups were treated with the usual analgesic routine. The subjects received the treatments for 30 minutes at every time and each subject will be assessed 5 consecutive days. Per day the subject received treatment twice daily after 4 and 8 hours of post surgery. Pain was evaluated using a standard 11-point visual analog scale (VAS) before the application of TENS and after application of TENS (24, 48, 72, 96, and 120) post operative hours. The study population comprised of 60 subjects aged between 25 to 50 years. To evaluate the effectiveness of modulated frequency VAS was measured five times and compared between the experimental and control group. There was a difference in median pain score over a period of time (P < 0.001) between the groups expect at base line (P = 0.854). This study revealed that there was a relief in pain between the subjects over a short span of time. Hence the TENS after abdominal surgery is beneficial for the subjects with abdominal surgery incision. Since, the treatment has no observable side effects, and the pain-reducing effect persisted for 5 days, it is advisable for the subjects.

In the present scenario of changing social structures, social values, and globalization, feeling of loneliness is becoming a serious problem among adolescents which may impact their well-being. The present study is evaluated the loneliness of single born male and female among college students. The researcher sample of 60 adolescents was selected from college in chennai city all are eligible participants of 30 males and 30 females. Each participant assessed with Revised UCLA Loneliness Scale (1980). The data were analyzed using "t" test. Results revealed that there is a significant different between male and female single born among adolescence.

Part or all of the mesh can be eliminated by using the compact support, the orthogonality and other properties of the wavelet function and the meshless algorithm to enhance the computing capability. A meshless algorithm was proposed based on the wavelet basis function. Combine the advantages of both wavelet function and meshless method. Wavelet transform is introduced into the element-free method to build the form that wavelet basis function meshless method formula. The method is applied in analysis of electromagnetic field. We give the method of discrete model, and use Lagrange multiplier method realizing essential boundary conditions. Numerical examples show the new method is effective for solving electromagnetic field.

Rural markets have become integral part of global market. The negative impact of all the recent economic crisis on urban India has been more than offset by encouraging performance in rural areas. To explore and understand rural market is crucial for any marketers today. Rural market is like goldmine with lot of difficulties. This needs to formulate a well designed strategy to feel the pulse of the rural consumers and to tackle the mystic rural market. Many companies go to rural markets, still to make money, not to guide or help or develop rural consumers. The rural marketers must think rural for long-term success instead of short-term profit. In this context this paper highlights the emerging trends and challenges in Indian rural Market.

MIMO technology plays a vital role in wireless communication which uses multiple antennas at both transmitter and receiver side. As the demand of data rate is increasing day by day, there is a need of high throughput, wide coverage, capacity and improved reliability. Integration of OFDM with MIMO holds the potential to drastically increase the data rate in future wireless communication system without increasing the transmit power and bandwidth. In this paper we mainly focus on the advantage of using MIMO-OFDM system and the drawback of using SISO, SIMO, MISO systems which have been verified using simulation. Performance of the systems is measured with respect to BER, capacity and finally the data rate is determined. The simulation results are obtained using MATLAB/SIMULINK software.

Today the world is at the risk of environmental disarray. The main reason is population explosion. The result of the uncontrollable population, forces us to maintain the inventory of all products at a higher level. The suppliers are comparatively lesser than buyers. To retain the confidence of the buyers, the suppliers seek logistics and packaging for the deliverance of the goods to the customers at the right time and in the right manner respectively. This paper deals with an Economic Order Quantity model (EOQ) which associates the package cost along with the costs of ordering, purchasing and holding. The need for packaging and the impact of its inclusion in the classical EOQ model together with transportation cost are discussed.

The level of implementation of quality control program (QCP) in diagnostic radiology facilities in Akwa Ibom state, Nigeria, was investigated. A total of thirty (30) diagnostic radiology centres took part in the study. A two part structured self completion questionnaire of thirty six items was the instrument used for data collection. Result shows that the level of implementation of quality control programme (QCP) in these diagnostic radiology facilities was low, importance of QC to the facility and radiation safety notwithstanding. This low level of implementation of QCP was identified with some fundamental factors namely, lack of radiation safety officers (RSO), lack of retraining programme for the medical personnel, lack of adequate funding, power and QC test equipment for the facilities. The aim of this investigation is to study the level of implementation of quality control programme which enhances radiation protection in diagnostic radiology facilities.
