Advancement in the field of embedded system and VLSI has induced the researcher in designing low power embedded systems and VLSI circuit design. The embedded systems are mostly batteries operated in nature. The power loss during static, dynamic and switching characteristics are tabulated. The switching nature in cmos constitutes a large value of power loss during the switching condition. Many research papers have been proposed in reducing the switching loss, and low power estimation, this paper clearly demonstrates the comparison of them. The main features of the dominated design techniques and methodologies of transistor level, gate level, RTL level, behavior level and system level are reviewed. The corresponding advantages and drawbacks, as well as comparisons between the techniques and the methodologies are also presented. The low-power design process such as transistor level, gate level, RTL level, behavior level and system-level models are explained.

The thermal evaporation system type (Edwards) has been used to evaporate high purity (99.9 %) silver on glass substrates at room temperature under low pressure (about 10-6 torr) for different thickness (50, 75, 100, 125 and 150) nm. Using a rapid thermal oxidation (RTO) of Ag film at oxidation temperature 350 oC and different oxidation times, Ag2O thin film was prepared. The optical properties of Ag2O film were investigated and compared with other published results. The gas response behaviors of the p-Ag2O/PSi/c-Si – based gas sensor to H2 gas were investigated. The film gas response dependence on the temperature and test gas concentration was tested.

The invasion of the orbit with metastatic tumors is rare. In addition, some cases of unilateral metastatic disease have been reported but more often it is bilateral involvement. Moreover, it frequently attends locoregional invasion of the orbit by tumors adjacent structures including intraocular tumors in children. In adults, the orbital metastases are mostly of epithelial origin and they are considered a full metastatic site [1, 2, 3, 4, 5, 6]. In the literature, many cases of orbital metastases have been reported, such as esophageal cancer metastasis [7], breast [8], pancreatic [9] as well as lung [10]. Today, metastatic carcinoma of the orbit are 2.3 to 7% of orbital tumors [11, 12]. Cancer of the prostate is the most common cancer in humans outside of skin cancer, and it often leads to bone and visceral metastases. [13] However, the orbital metastases appear at an advanced stage of the disease [3, 4]. The purpose of this article is to report the case of a bet diagnosed with adenocarcinoma of the prostate revealed a metastatic orbital tumor.

This paper deals with an analysis of rotation effects on unsteady free convective flow past an impulsively started vertical plate with variable mass diffusion in the presence of transversely applied uniform magnetic field. The problem is solved analytically using the Laplace Transform technique. A selected set of graphical results illustrating the effects of various parameters involved in the problem are presented and discussed. The numerical values of skin-friction have been tabulated.

Aim: To assess the long-term effects of antioxidants in individuals according to age and sex distribution. We studied the effects of antioxidant functional foods and nutraceuticals on Malondialdehyde (MDA) level. Methods: The studied subjects included a total of 150 healthy adults of 96 men and 54 women aged between 30 and 74 years. At the baseline visit, eligible candidate were randomized to either 1 capsule per day of antioxidant nutraceutical or antioxidant functional foods or placebo, and the first dose was dispensed and followed up for six months. Results: The results were grouped based on gender and age ranges, positive decrease in the MDA after antioxidant dietary intervention and lower concentration in men than in female at some age ranges was observed. Conclusion: We suggest the use of antioxidant functional foods as an alternative to antioxidant nutraceuticals/functional foods in reducing the effects of MDA in either healthy or stressed individuals.

Stress has been viewed as an inevitable consequence of work life. A worker will fell stress when his or her does not match their job requirements. Work stress come from a variety of sources and it can affect people in different ways. In the report The Scale of Occupational Stress (Smith et al., 2000 in Jeremy, 2005) it was estimated that there were 5 million workers suffering the high level of stress at work. The study shows the important outcomes that approximately one in five workers reported stress arising from work. There were cause by excessive workloads or lack of managerial support, ill health and back pain, together with certain health related activities such as smoking and alcohol intake.

From the experimental verification, as expected the mechanical properties of foamcrete were reasonably low when compared to normal weight concrete. Nonetheless there was a potential of using foamcrete as fire resistant partition or as load-bearing walls in low-rise residential construction. In order to demonstrate the feasibility of this proposal, this paper presents a preliminary feasibility study on its fire resistance and structural performance of foamcrete based system. The objectives of this feasibility study are tp investigate the fire resistance performance of foamcrete panels of different densities (650, 800, 1000, 1200 and 1400 kg/m3) when exposed to fire on one side for different fire resistance ratings based on insulation requirement and to examine whether the composite walling system had sufficient load carrying capacity, based on compression resistance at ambient temperature.

This is research paper is based on organizational stressors are also called as job related stressors. Some of the important job related causes of stress are as follows Role conflict, Role ambiguity, Organizational structure, Working conditions, Rotating shifts, Work overload, Work under load , Lack of participation in Decision making, Organizational leadership, Poor performance of the organization. The stress can have effect on the individual, the group, organization and even the family members. The degree of effect depends upon: Duration – The length of period of stress, Strength - The degree of stress, Individual Characteristics – Physical and psychological features to cope up with stress. Normally, prolonged exposure to stressful produces serious physical, psychological and behavioral effects. The effects of stress are as follows: Effects on physical health, Psychological health, and Alcoholism and drug addiction, Burnout, Effect of stress on organization behavior. The researcher tried to cover all aspect of the research study to emphasized that the impact of research among Mumbai Police Force‘s personnel and professional life.

The Schiff base, 3-{[(6-methoxypyridin-3-yl)imino]methyl}-5-nitrophenol, formed by condensation of 5-amino-2-methoxypyridine and 2-hydroxy-5-nitrophenol; and its metal(II) complexes{where M = Mn, Co, Ni, Cu, Zn, Pd} have been synthesized and characterized by %metal, melting points, IR and electronic spectroscopies. The complexes analyse as [ML(NO3)] with the exception of the Ni(II), Cu(II) and Pd(II) complexes which analyse as [MLCl(H2O)] respectively. The IR data confirm that the Schiff base coordinates via the imine nitrogen and phenol oxygen atoms; while the electronic data support a 4-coordinate tetrahedral/squareplanar geometry for the metal complexes. The metal complexes are air-stable solids, which melt/decompose on heating in the temperature range 228-390 oC; while the metal–free Schiff base melts at 208-210 oC. The in-vitro antibacterial studies reveal that the Schiff base, its Co(II) and Zn(II) complexes have a broad-spectrum antibacterial activity against Bacillus cereus, Pseudomona aeuriginosa, Staphylococcus aureus and Proteus mirabilis with inhibitory zones range of 14.0-22.0mm.

This study investigates the learning strategies of students for the reading comprehension courses in a semi-distance educational system in Iran called Payam-e-Noor University with over 500,000 students in different branches all over the country. By using qualitative data, i.e. interview, this study intends to examine the viewpoints of students regarding how the reading comprehension tests in Payam-e-Noor University can influence the way they learn. The results indicate that the washback effect works quickly in bringing about changes in learning strategies of students.
