Absorbed dose rate and annual effective dose estimated for occupational workers for Goldmines in Ghana that uses nuclear gauges in their operations and external ionizing radiation exposure during cargo radiographic inspections were measured as part of the authorization process for the use of ionizing radiations sources in Ghana. The measurements reported in this paper were made with portable radiation monitor which employed GM tube and was calibrated against secondary standard dosimetry system and a data for a five-year period (2010-2014) was compiled from the RAIS of the Ghana Radiation Protection Board. The average absorbed dose rate in air for Goldmine workers was 0.73µSv/h with an annual effective dose of 1.45 mSv while the average external radiation dose for workers and members of the public during cargo inspection was 0.23 µSv/h for Cobalt 60 scanners and 0.1 µSv/h for x-ray scanners and the annual effective dose for both workers and members of the public for Cobalt-60 and X-ray scanners were 0.46mSv and 0.2mSv respectively. It was concluded that the prevalent radiation levels did not pose any significant radiological health hazard to workers and members of the public.

In this work had be determine the ratio of the drift velocity to the diffusion coefficient W/D to calculate the motion of free electrons in air and helium gas. The following parameters of the electronic motion were determined as a function of the electric field strength E, apparent energy factor, K1 and Townsend energy factor, KT for Helium gas and air at 300?K and 288?K respectively in case of Maxwell and Druyvesteyn distribution law. The transport equation solved numerically to obtain the transport coefficients values and had be fed to the equations to calculate the above parameters. The gas parameters are obtained and compared with available experimental data.

Glomerulonephritis is a group of renal disorders in which the major injury involves the glomerulus rather than the tubules, interstitial tissue, or vasculature. In glomerulonephritis, there is remarkable variation in clinical appearance, disease etiology, management strategy and diagnosis. The prime intention of this review is to provide detail information about Glomerulonephritis; its genesis, etiology, epidemiology, symptoms and diagnostic parameter for identifying acute and chronic glomerulonephritis. This review article focuses on the major treatment which includes Allopathic and Ayurvedic medicine available for treating the conditions of glomerulonephritis. Apart from this it also provides information about precautions and home remedies which are available for the treatment of Glomerulonephritic syndrome.

Character recognition, usually abbreviated to optical character recognition or shortened OCR, is the mechanical or electronic translation of images of handwritten, typewritten or printed text (usually captured by a scanner) into machine-editable text. It is a field of research in pattern recognition, artificial intelligence and machine vision. Though academic research in the field continues, the on character recognition has For many document-input tasks, character recognition is the most cost-effective and speedy method available. And each year, the technology frees acres of storage space once given over to file cabinets and boxes full of paper documents. The objective of this paper is to identify handwritten characters with the use of neural networks. We have to construct suitable neural network and train it properly. The program should be able to extract the characters one by one and map the target output for training purpose. After automatic processing of the image, the training dataset has to be used to train “classification engine” for recognition purpose. The program code has to be written in MATLAB and supported with the usage of Graphical User Interface (GUI).

This article examines the potentials for developing health-based tourism in the state of Perak. The discussion begins on the distribution of hot springs frequented for various ailment treatments in Perak. The second part of the paper identifies and analyses challenges and opportunities for potential development of health based tourism in the state. Lastly, it discusses issues associated with developing policies promoting tour sites. Current global trends in tourism activities leads into increased domestic trips for short distance tourism. The fast changing lifestyles among state residents help increase awareness and concern for health care activities that utilise natural resources uniquely available in different hot spring parks. This situation increased competitiveness among tour locations. Each individual hot springs has the potential to market its own strengths and uniqueness by promoting the local content either based on natural resources or man-made physical attractions. In this context, marketing strategies must identify and emphasise strengths and characteristics of each location to stimulate increase in tourist return. Quality issues are also one of the main attractions to be considered in future global tourism policies. Using SWOT analysis, factors influencing site selection and priority development strategies based on place consumerism factual information, consumer perceptions and capacity of place, and future potential hot springs in Perak state as a health tourism destination will be evaluated and discussed.

Digital libraries are getting popularity among the users. On One hand they are giving opportunities to access information round the clock 365 days on the finger tips of the users but on other hand, users are not coming to libraries because access of information is available at their workplace, be it office or home. Even users can access digital libraries while they are on the way or driving, if they are connected to internet. But this is not a good sign for libraries, because the very purpose of establishing them is diminishing. Hence, there is a need to develop strategies to attract the users in digital libraries so that they come and make use of documents and other things in libraries. This paper attempts to discuss the present situation and possible solution to overcome the problem so that the users may come in libraries personally and use them.

Composites are currently receiving much attention due to their tuneable chemical and physical properties. ZnO -Al₂O₃ composites attract particular interest because of their possible applications in dye-sensitized solar cells and sensors. Zinc oxide - Aluminum oxide composites were synthesized by hydrothermal method. The precursors used were Zinc Acetate, Aluminum nitrate and Sodium hydroxide. X-ray diffraction (XRD) pattern indicated that the synthesized Al₂O₃ was of hexagonal structure. Thermogravimetric analysis (TGA) was done to determine the thermal properties of the nanopowder UV-Vis spectroscopy and Dielectric analysis were done to determine the optical and dielectric properties of composite.  The results were further discussed.

The purpose of writing this paper is to identify, measure and prioritize the driving affecting factors on Abyek Company (Iranian cement producer) situation in markets. For conceptual framework, 3 main criteria and 13 sub criteria were considered. First of all, by applying Chi-square test, the factors were surveyed in which all 3 ones were affective on compatibility. Also the results of utilizing Average test show that all 3 criteria were placed in favorable place. And finally by using fuzzy TOPSIS technique, the indices were ranked in which “customer relationship management”, “innovation in product” and “competitors related intelligence” were selected as the most important sub criteria.

All real systems that work with digitally represented data require error detecting codes because all real channels are noisy to some extent. The basic goal is to detect errors in data transmission over unreliable or noisy communication channels. Encoding and decoding techniques play a major role in digital communication as the received bit stream usually contains a number of errors. Cyclic Redundancy Codes (CRCs) provide a first line of defense against data corruption in many networks. The basic goal is to control errors in data transmission over unreliable or noisy communication channels. CRC code provides a simple, yet powerful, method for the detection of burst errors during digital data transmission and storage. In this paper simulation is shown and implementation of CRC-32 is done on TMS320VC5416.

In this paper design special frame vertical axis wind turbine and test in the wind tunnel. This design is presented as vertical locations of the three movable vanes that create scoop shape when closed. Scoop shape of frame increases the drag factor and increase the torque, in the other side of impeller movable vanes are opened under action of wind and the air pass freely to reduce the negative torque. Fabricate two models of impeller with movable vanes and with fixed vanes model and test it in wind tunnel. The maximum power coefficient for three frames movable vanes is 0.32 and higher than the same dimensions of model with fixed vanes about 11%.
