Post weld heat treatment and subsequent aging (PWHTA) effect on dissimilar friction stir welding (DFSW) (AA2024-T6 to AA6351-T6) were investigated in the present study. The micro structural measurement techniques (Optical, SEM- EDS) have been employed to understand the precipitate distribution and the elements distribution in the Stirred zone (SZ). PWHTA on dissimilar FSWs shows better mechanical properties and pitting corrosion than as welded specimens. A post weld solution treatment at 5200 C for 1 hr and subsequent ageing at 1800 C for 12 hrs and 8 hrs aging time resulted in better mechanical and corrosion properties respectively than other conditions.

This study examines the relationship between the organizational climate and organizational trust with the participation level in the decision-making of the managers of the Youth and Sports offices in Ardabil Province. The research methods descriptive-correlative and the research objectives are applied ones. The statistical population of the study included all the managers of the offices of youth and sports of the organization of physical education in Ardebil province, which consisted of 70 individuals. In order to collect then formation about organizational climate, standardized Organizational Climate Description Questionnaire (OCDQ) by HalpinandCroft(1963), to assess the level of organizational trust, Organizational Trust Questionnaire by Allal(2008) and to evaluate the participation in decision-making, researcher made questionnaire were used. Results of this study indicate that there is a significant and positive relationship between the dimensions of organizational trust (lateral trust, vertical trust, institutional trust) and the employee participation in decision making, that is, as the institutional trust increases, the employee involvement in decision making increases significantly. These results help the managers to decrease or increase the employees’ participation in organizational decision-makings, and so doing, enhance organizational climate and organizational trust toward the organization and its management.

Education is vital for sustainable economic development and empowerment of people. Subsequently, the role of education especially for the emancipation of the poor and marginalized cannot be underscored. Realizing this fact, the Government of Kenya has invested immensely in education by providing free primary and free tuition in secondary education. Public university education is also subsidized. Despite these initiatives, investment in basic education in Kenya represents a largely unequal distribution of resources. The most deprived area is North Eastern province of Kenya partly due to its arid and semi-arid nature that make development a theoretical and a practical challenge. This paper applies human capital theory and human rights theory to advocate and promote education for all especially for children of pastoralist communities in Kenya. By applying the human capital theory, the paper argues that the rate of returns to education, both private and social, justify a greater investment in educational initiatives in North Eastern province. The argument is supplemented by the human rights theory that argues that even if there would be no significant returns to education in arid areas, the Government has an obligation to ensure that all children, regardless of their socio-economic and political context, attain quality education as a human right that has to be respected.

The Falcon SB-40 concentrator is an enhanced-gravity separator used in mineral beneficiation, as their superior gravity field enables them to separate particles within narrow classes of density and size. The process of cutting and finishing garnet mineral produces industrial waste as a fine powder mixture of garnet with a few percent of titanium carbide which is derived from titanium blades. This study aims to shed light on the Falcon concentrator’s ability to separate particles within density ranges lower than usual. Specific gravity of the fractions is 3.7 and 4.9 gm/cm3. Various operating conditions such as bowl speed (G force), water pressure, pulp solid ratio and pulp feed rate were investigated. It was shown that under optimized conditions the Falcon SB-40 concentrator can produce an excellent titanium concentrate with titanium carbide of 92.2 % from a feed waste of about 5% titanium carbide with total recovery of 97%.

In every age and for every nation, God nominated prophets and apostles for the reformation of society through His revealed commandments for smooth running of the discipline of this world. Throughout history, the fundamentals preached by all the prophets were the same, i.e. Oneness of God, Prophethood and the hereafter. The religion preached by all the prophets was the same but commandments and rituals remained different to some extent. The teachings about the ways of offering Prayer and fasting, the prohibited and the permitted, the ways of ablution, purification and bathing in different sharias remained different. The present study compared the existing literature on the significance and philosophy of worship in Islam and Judaism for finding the similarities and differences in both. To this end, this study adopted a pure speculative analytical approach to arrive at a conclusion. The study found that in both the Islamic Law and Moses’ law worship has similar purpose. Both the laws consider worship is a source of bringing man closer to his Creator, purifying his soul, improving his deeds and making him a better human being and thus resulting in a peaceful society based on social welfare and collective good.

SPKMP is a public programme with the objective of uplifting the level of wellness among coastal community particularly the poor households. Since its inception in 2001, the programme has undergone several phases of improvement. However, until now living conditions of the coastal poor households remain unchanged. The present study aimed at assessing performance of SPKMP in terms of implementation of the program as well as the performance of the organizations that involved in the program, particularly looking into the mechanism used in managing the program with special reference to district of Kuala Terengganu. By using official records and reports from various agencies at the central level and district offices besides observation and in-depth interviews with households and officials at the agencies involved, the study discovered some interesting findings. Firstly, the principles serve as a guideline for the implementation of the program were not followed by the implementing agencies at the district level. Various malpractices were also detected. Secondly, the evaluation showed that most of the program outputs cannot help the fishermen to increase their household income and savings. Thirdly, the marine resources are depleting, therefore the fishermen are not able to increase their catch. Furthermore, coastal communities have not received sufficient assistance in the program so they do not get the necessary moral support. This study shows that the development agencies have not been able to implement the program properly because of weak and inefficient management. Policies, strategies and activities that are more suitable are needed to improve the program.

The study considered the transport of a radioactive solute in solution from the ground surface down through the soil to the groundwater when there is an accidental or intentional spillage of a radioactive material on the surface. The finite difference method was used to model the spatial and temporal profile of moisture content in a soil column using the ?-based Richard’s equation leading to solution of the convective-dispersive equation for non-adsorbing solutes numerically. A matlab code has been generated to predict the transport of the radioactive contaminant, spilled on the surface of a vertically heterogeneous soil made up of two layers to determine the residence time of the solute in the unsaturated zone, the time it takes the contaminant to reach the groundwater and the amount of the solute entering the groundwater in various times and the levels of pollution in those times. The model predicted that, when there is a spillage of tritium, on the surface of the ground at the study area, it will take two years for the radionuclide to enter the groundwater and fifteen years to totally leave the unsaturated zone. Therefore, it is very important that proper containment measurements be put in place to take care of such spillages since they have long term effect.

The title compound of C2H5NO2•Ba (NO3) Glycine Barium Nitrate (GBN), a semiorganic glycine additive material has been grown from slow evaporation solution growth technique at room temperature.. The grown single crystals have been analyzed by powder crystal X-ray diffraction. The title compound has good optical transmission in the entire visible region. The optical band gap has been estimated using Tauc’s plot. Its relative SHG efficiency has been tested by Kurtz powder method and it quite interesting that it acts as poison, not favoring NLO efficiency. Thermal stability of the grown crystal was investigated by thermo gravimetric and differential thermal analyses.
