Conducive organizational culture has been proved to be imperative for an efficient organizational performance. Organizations that ensure a favorable work environment for their employees are able to achieve a higher level of professionalism than others. Literature also reveals that a diverse workforce has advantages of more dynamic knowledge, variety of experiences from different backgrounds and multicultural pool of human capital that help create an improved organizational climate through better work involvement, supervisory support, innovation & flexibility, clarity of goals and welfare. Thus if ethnic diversity is integrated with organizational culture of an organization, then it creates a better work environment that leads to an enhanced employees’ productivity. The study was conducted on two higher level educational institutions in two different countries: a university in Pakistan having a homogeneous workforce and a college in the Sultanate of Oman carrying a heterogeneous workforce where diversity is integrated with organizational culture as a diverse work force from many different cultural backgrounds and nationalities is working in Omani educational institutions. After data analysis, it was found that faculty members working in a diversity integrated culture have a better perception about their organization than those serving in a culture without diversity. It was concluded that Employees perceive an organizational culture as more attractive and better in which workforce in ethnically diverse, which also means a favorable organizational climate.

Background: Iron oxide nanoparticles can be used for medical imaging, disease diagnosis, drug delivery, cancer treatment, gene therapy and other cases. These particles accumulate in liver cells and lead to oxidative stress with generation of reactive oxygen species. Aim: This study investigates the effect of iron oxide nanoparticles on liver tissue and enzymes [alanine aminotransfere (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP)] in male rat. Methods: 40 adult male rats of wistar strain, weighing 250-300 g were used for this study. The rats were randomly assigned to four groups. One group was control and other three groups were fed with iron oxide nanoparticles at 20, 50 and 150 µg/kg concentrations respectively for 15 days. Venous blood was taken to measure liver enzymes at the end of treatment. Liver of rats removed for histological experiments. Results: Significantly enhanced (P<0.05) AST level obtained as well as ALT and ALP level with used of maximum concentration of iron oxide nanoparticles (150 µg/kg) as compared to normal group. Conclusion: Based on our result, using high concentration of iron oxide nanoparticles could be caused undesirable effects on liver with damage to hepatocyte and level elevation of liver enzymes.

A Multi Hole pressure Probes (MHP) with five holes and conically shaped was designed for Air craft data sensors for calibrating the total pressure, static pressure, flow angle and flow speed. The main principle of five-hole probe is based on the notion that Mach number, pressure and directionality of the incoming stream may correlated with the combination of pressure readings. The general aspects of the five-hole conical probe were studied by various research papers and concluded with the final design of conical probe with 600 included angles which is applicable Air craft data sensors and also for both subsonic and supersonic wind tunnel test sections. Numerical calibration using ANSYS FLUENT 14.0 is done.

The present study deals with impact of physical factors on extracellular cellulase activity of some dominant post-harvest fungi. Post-harvest fungi were isolated from different varieties of papaya fruits by agar plate method. Out of 20 species 10 species of fungi were selected to study their cellulase enzyme activity. Different physical parameters such as light, incubation period, temperature and pH were studied in order to determine the optimum conditions for cellulase production of ten dominant fungi. The cellulase present in the broth was assayed by cup-plate method. It is observed that cellulase activity of post-harvest fungi was found to be optimum at temperature 200C, pH 6.0-6.5, incubation period of 20 days and continuous light

The objective of this study was to describe the growth pattern in Zandi sheep using non-linear models. In total 21640 body weight records from birth to yearling were analyzed. The data set were used in this study, obtained from the Animal Breeding Center of Iran during 1992–2013. In this study growth pattern parameters (mature weight, growth rate and mature rate) estimated using four nonlinear regression model (Brody, Gompertz, logistic and Bertalanfy). Growth models were compared with coefficients of determination )R2(, adjusted coefficient of determination (R2adg), Means square error (MSe) and Akaike’s information criterion (AIC). logistic model provided the best fit of growth curve due to the generally greater values of R2 and R2adg and lower values of MSe and AIC than other models. In logistic model the estimated amount of mature weight (A), growth rate (B) and maturation rate (K) were 34. 48±0. 09, 7. 61±0. 28 and 0. 027±0.0004, respectively. This amount for Brody model were 36. 52±0. 17, 0. 9±0. 004 and 0. 009±0. 0002 respectively. For Gompertz model this amount were 35. 12±0. 11, 2. 25±0. 04 and 0. 017±0. 0002 respectively. In von Bertalanfy model the estimated amount of parameters A, B and K were 35. 48±0. 12, 0. 53±0. 006 and 0. 014±0. 0002 respectively.

Binary pseudo random noise sequences are sequences of 1’s and 0’s having properties which make them appear to be noise-like but yet are deterministic. The NO-Kumar sequences were discovered by Jong-Seon No and P.V.Kumar and are known to have optimal correlation properties and a large linear span. The families of NO sequences are periodic with period = 2n-1 where ‘n’ is an even integer and contain within them a GMW sequence and also small set of Kasami sequences as special case. In this paper we investigate the properties of these sequences such as balance, run and even correlation properties. Odd correlation properties of these sequences which are not described in the NO-Kumar paper are also highlighted. The sequences are first simulated in MATLAB and then implemented by writing a Verilog code on the Nexys 4 FPGA board.

A study in gully erosion management on lateritic soil is a critical issue in West Bengal. In this paper, we have used field plots data, in combination with vegetation and check dams, for all aspects of lateritic soil erosion management. A program for controlling gully erosion was carried out in Rangamati in lateritic soil region of western part of West Bengal from 2011 to 2012 include two approaches “Check dam” and “Vegetation cover”. Results indicated that at the initial stage, the percent of sand was maximum in the upper catchment of each gully basin and the concentration of silt and clay is less. Gradually as vegetation starts trapping the sediment composition of soil changes registering higher percentage of finer particles. Again, the nutrients detached from the upper catchment were arrested by check dams that induced nutrients supply and water storage, which in turn, increased the growth of vegetation. This result proved the significance of vegetation cover with check dams to curb soil erosion and it may help the planners and managers to take proper decision for the conservation of lateritic soil.
