Machining is the most important of the manufacturing processes which involves the process of removing material from a workpiece in the form of chips. Machining is necessary where tight tolerances on dimensions and finishes are required. Being such an important process in manufacturing industry, a machining process is considered for investigation in the present work. This paper presents the experimental investigations on the effects of cutting variables like Spindle speed, Feed and Depth of cut on the Material removal rate and tool wear. The experiments were conducted on AISI SI steel grade on a CNC turning machine using ceramic insert. The experiments were conducted as per the design of experiments. Initial trial experiments were conducted to fix the ranges for the control parameters. After conducting the experiments the MRR and Tool wear were measured and recorded. The effects were studied after plotting the graphs between the Input process parameters versus the responses using Design expert software. The results obtained in this study can by further used for optimizing the process parameters there by the optimized results help the operator to enhance the quality as well as machining rate

In connection with conversion of Ghana Research Reactor-1 (GHARR-1) from the use of Highly Enriched Uranium (HEU) fuel to the use of Low Enriched Uranium (LEU) fuel with power upgrading which started in 2006, it is imperative to know how the spent fuel is stored. After the conversion process, the current HEU core will need a Spent Nuclear Fuel (SNF) storage cask to store the HEU fuel. Studies into suitable spent fuel storage cask are ongoing to help solve this challenge. The photon source densities of fission products, actinides and activation products relevant for assessing radiological consequence as well as designing and fabricating Spent Nuclear Fuel storage cask for GHARR-1 using local shielding material has been estimated for its 90.2% HEU fuel. Results showed that the bounding radiological dose due to hypothetical accidents can be evaluated at the end of irradiation (at discharge). Results have also proven key to the selection of shielding materials for the SNF cask.

This paper reviews the newly developed statistical analysis technique: classification and regression trees (CART), which is one of the most frequently used methods for complex and multi dimensional data sets. CART is a non parametric approach and can easily be used. A most popular and commonly used Gini index method for node impurity in classification trees and the concept of standard error for the measurement of accuracy in regression trees has been discussed. Important features and uses of CART in different fields especially in medical research have also been discussed with examples.

In this study an extended geophysical survey using gravity and high angle refracted seismic methods with recorded earthquake has been carried out in Kerman province in southeast of Iran. The purpose of the applied geophysical surveys was to provide information on crustal structure and lithospheric thickness. The purpose of this research is focused on determination of Moho depth and for this reason several profiles for both methods were performed and by use of topography and gravity data with a reasonable combination with high angle refracted seismic data and earthquake record, the crustal and lithospheric thickness of Kerman province was calculated. Oldenburg- Parker algorithm was the base of gravity survey of the present work but by use of Matlab programming environment and generated C Sharp computer codes was optimized, improve and then executed. The key factor of this study was generated computer code, which named as “MOHO R.A.T 1.01”. For seismic data, a least-squares analysis of the travel-time data was made and the uncertainties were taking in to account. Finally, depth calculations for the velocity discontinuities and gravity anomaly contour maps were made. The comprehensive comparison between the obtained results and other studies on the selected area showed good agreement, which verified the ability of produced code.

The aim of this study is to identify the impediments of developing medical tourism in Iran and categorize and prioritize them. Therefore, we interview 30 managers and key players in the industry of medical tourism which were in hospitals or medical tourism agencies. After extracting the important involved factors from our interviews, we design our questionnaire which was consist of 36 questions and distributed to 284 people in our sample. For analyzing data, Friedman test and t test were performed which use of SPSS 18 software. The results showed us the priority of the identified impediments is: factor conditions, strategy and structure, supporting industries and demand condition. According to our results we can say that government as a supporter in this industry can have crucial rule for setting rules and preparing safe and stable environment.

The rationale of the present research is to understand how and to what extent a particular leadership style can affect the climate of the organization. And further to find out the most popular form of leadership on the basis of data collected from both public and private sectors respectively. The real leadership is measured by its impact on others and in creating organizational climate which focuses on employee wellbeing. The questionnaire was conducted on 105senior personnel in education sector to determine their leadership style and further to study the effectiveness of each style on the climate of the organization. Results: There is a difference in leadership styles of different educational institutes and in turn their impact on climate of the institute. The leadership styles prominently emerging are participative and catalytic. Implication: Success of the organization depends on its leader. Participative leaders are those who involve other people in the process, including their subordinates, peers, superiors and other stakeholders. The Catalyst Leaders are visionary, they have facilitative, innovative, inspiring vision and empower people to transform the vision into reality. The paper reports that the different leadership styles create different type of climate which is responsible for the over all wellbeing of the employees and the institute. In today’s world successful leaders are those who provide opportunity and training to everyone to develop to the next level.

The aim of this study is to know if relaxation has immediate effect on hemodynamic parameters and pulmonary functions in normal healthy individuals. 34 of 40 participants were selected after screening. These participants were divided in two groups, group A: music therapy, group B: Jacobson’s progressive muscle relaxation. After an interval of 5 days, the participants were given the other intervention respectively. The participant’s hemodynamic parameters and pulmonary functions were noted immediately before and after the session. The study was conducted in the department of Cardio respiratory physiotherapy, College of Physiotherapy, PIMS, Loni. India. 34 of 40 normal healthy participants entered the study and 30 completed it. Relaxation was given by two techniques, music therapy in which the participant was made to listen to Indian classical instrumental music for 20 minutes. Another technique used was Jacobson’s progressive muscle relaxation for 20 minutes. Outcome measures were noted pre and post session. The primary outcome measures were hemodynamic parameters and pulmonary function. The secondary outcome measure was to find participant’s preference of relaxation technique based on their experience. The hemodynamic parameters improved considerably after music therapy but the pulmonary functions improved better with Jacobson’s progressive muscle relaxation. The participants rated music therapy more preferable than Jacobson’s progressive muscle relaxation. Relaxation has immediate effect on hemodynamic parameters and pulmonary functions. Relaxation particularly music therapy (Classical Indian instrumental music) can be made a routine activity in normal healthy individuals.

The ever-increasing energy consumption, fossil fuels costs and exhaustible nature and worsening of global environment have created a boom to renewable energy based generation system. Among the renewable energy sources, solar and wind energy are infinite and high potential sources. Thus the fusion of these two energy system is best suited for the reduction of fossil fuel in energy generation. When is connected to grid, it causes power quality problem because of its fluctuating nature. This proposed work describes the methodology for improving power quality of the grid system interfaced with hybrid wind-solar system. The proposed topology is validated through dynamic simulation using the MATLAB/Simulink Power System Toolbox.
