Burnishing process is widely used to produce excellent surface finish, hardness and compressive residual stresses by plastically deforming the workpiece surface for the various types of materials such as steel, copper, brones, aluminum and thier alloys. Many works have studied the effect of burnishing on surface characteristics of different materials. In this work the optimum parameters of burnishing process on Friction Stir Welded joints of Aluminum 7075 T6 alloy are investigated by testing the effect of different burnishing parameters i.e. table speed, burnishing force, and transverse feed rate on Friction Stir Welded joints and study the mechanical behavior before and after burnishing process. It has been found that good surface finish is achieved at low burnishing speed and transverse stroke with burnishing force around 200 N, high micro-hardness and high bending strength can be obtained at low burnishing speeds and low transverse stroke, with high burnishing force where as a high tensile strength is obtained at high burnishing speeds due to directional deformation of grains and the orientation of residual stresses.

A 9 year old sahiwal cow as subitted for postmortem following death in a farm housing 100 animals of various breeds of India. Grossly, the animal showed subcutaneous adipose tissue gelatinisation and oedema with streaks of haemorrhage in the submaxillary space, pharyngeal region, neck, dewlap and brisket region. Fibrinous adhesions between the pericardium of heart and ventral aspect of lungs. Thoracic cavity revealed yellow fluid with fibrin shreds. Pericardial sac showed thickening with thick dirty white fluid. Samples collected from different organs were cultured followed by multiplex and species specific Polymerase chain reaction which consistently showed Mannheimia haemolytica in all the organs. Histopathology showed that the alveolar spaces were diffusely filled with sero-fibrinous exudates admixed with neutrophils and red blood cells. Interlobular septa were thickened and markedly distended with fibrinous exudation. None of the other animals housed showed and symptom or mortality. This isolated case of mannheimiosis could be due to unknown stress which has led to the multiplication of the organism leading to death of the animal.

Examination by whatever name it is called is very important to educational system as air is important to life. Examination serves very many useful purposes at any education system and level. The useful purposes of examination at any education system can be marred by its conduct especially if it allowed for examination malpractice. Examination malpractice is one of the plagues that be devilled tertiary institutions in Nigeria. Examination malpractice in the tertiary institutions is on the increase daily taking different forms and dimensions. However, the menace thrives well when examination invigilation is very slack. Examination invigilation rests solely on invigilators and other stakeholders in the conduct of examinations invigilation. Therefore, examination invigilators determine the quality of examination invigilation. Effective invigilation of examination can only be made possible through effective invigilators who will reduce if not totally eradicate the menace of examination malpractice and this is the thrust of this paper.

“The only thing of real importance that leaders do is to create and manage culture.” “If you do not manage culture, it manages you, and you may not even be aware of the extent to which this is happening.” (Edgar Schein).Organizational Culture is one of the most important construct in management research. This exploratory study elaborates the impact of organizational culture on organizational performance. This study is conducted in different Bahawalpur based franchises of telecom companies. The purpose of this study is to determine the impact of organizational culture on organizational performance in order to know that how culture of an organization assist in enhancing the organizational performance. Balance score card is used to measure the organizational performance. Quantitative approach is adopted in which a questionnaire is used to collect the data. The questionnaire is adopted from a previous study. 22 questionnaires have been distributed to the research participants out of which 15 questionnaire are returned to the researchers with complete information. The findings indicate that all the dimension of the culture influence the different perspective of organizational performance. Research also indicates that if the norms and value of employees are according to organization then it is beneficial for achieving the organizational objective. The findings also indicate that the uncertainty avoidance is high in these companies and roles and procedures are clearly defined .The findings revealed that these companies are characteristised by high masculinity which means the managers are effective, more assertive, result oriented and value the final outcome. It is also revealed that there is a power distance between the managers and the employees because only few employees are agreed with the statement that there manager is accessible and visible. The findings indicate that these telecom companies are inclined towards collectivism due to which workers are more sati

As Direct filtration provides an alternative treatment process to coagulation and settling of low turbidity waters used for the treatment of good quality water supplies. The primary objectives for using a direct filtration treatment in municipal plants are to obtain quality water, at minimum coagulation dosage, without sacrificing filter production capacity.

This letter shows a significant improvement procedure to reduce the path loss for Hata Path Loss model. This can be applied for urban, suburban and open areas in different frequencies. This is completely a software based approach to determine a relation between the path loss and the height of the receiver antenna. Here it is shown that if the height of receiver antenna is increased then the path loss decreases significantly.

Information and Communication Technology (ICT) stands out as a major driver of the modern age. It espousal in virtually every sector of the economy led to a paradigm shift from conventional way of work arrangement to a new form of work system, workplace hazards as well as employee’s behavior across the globe. This study examined the effect of work system and workplace hazards on employee’s behaviour. It aimed at addressing the issue of how work can be structured in order to reduce workplace hazards and produce affirmative employee’s work behavior. The study adopted survey research method. Participants in the study were 120 staffs of Nigerian Eagle Flourmill, Ibadan who were selected through stratified and simple random sampling techniques. Data were collected via responses elicited using the questionnaire instrument. Results show that there is a significant relationship between work system, workplace hazards and employees behaviour. The findings were discussed with reference to relevant empirical literatures, and with recommendations for management of organizations both for practice and future research highlighted.

Tripura is a small hilly state of northeastern region of India. Before it was amalgamated with India, it was a princely state. The rulers of Tripura wanted to modernize their state and hence they feel the necessity of modern education. In the year 1862, first time the step towards modern education was taken by establishing a school. From that time onwards, the journey of modern education was started and before Tripura became a full-fledged state on 1972, the growth and development of education in Tripura reached towards a satisfactory level. This writing is a historical investigation into the growth and development of education from the inception of modern education in Tripura from 1962 to 1971.

A longitudinal study was carried out to determine the prevalence and incidence of mastitis in lactating dairy cows from November 10, 2011 to June 25, 2012 in six purposively selected smallholder dairy farms in Hawassa and Wendo- Genet districts, Ethiopia. The study was carried out through field screening surveys by California mastitis test for each quarter milk sample, followed by retesting negatives group for mastitis twice a month during the study period to estimate the incidence of mastitis. At the time bacteriological examinations to identify the causative agents from mastitis positive cows were carried out. A total of 122 milking cows were examined, out of which 77 (63.1%) and 152 (31.1%) were found positive for mastitis on the basis of California mastitis test at cow and quarter level, respectively. Out of the total quarters examined, 25 (5.12%) were recorded as a blind teats. The incidences of mastitis were seen to be 0.49 in three month study period. Slight variations in incidence rate between different farms were revealed. Higher incidence rate of 0.54 was recorded in cows kept in bad concrete in comparison to cows kept in good concrete which is 0.41. On the other hand, higher incidence rate was recorded in single and three or above parity; in early and late stage of lactation. Proportion of bacterial isolates isolated from mastitis cows showed high proportion of Staphylococcus species (52.9%) followed by Streptococcus species (23.5%), Bacillus species (9.8%), E. coli (7.8%) and Corynebacterium species (5.9%). It was concluded that there was a higher incidence and prevalence of mastitis, mainly caused by Staphylococcus species and Streptococcus species. Based on the findings, recommendations were made accordingly to concerned organs.

Analysis of the influence of defects, created in irradiation process at nuclear accelerators or during mechanical and heat treatment of superconducting tapes in the technological process, on the current-voltage characteristics of superconducting multi-layered materials is given. New approach taking into account inter-layers interaction is proposed and results of calculations presented, which are in accordance with experiment. The magnetic field dependence of the critical current is theoretically deduced, which relation is useful then for analysis of the dynamical anomalies of the current-voltage characteristics in HTc superconductors. New solution of the magnetic diffusion equation into HTc superconductors is proposed, which predicts results concerning dynamical anomalies being in agreement with experimental data.
