This paper reports the effects of sintering schedule to the mechanical properties and microstructure of warm formed powder compacts. Iron powder ASC 100.29 was used as main powder constituent whereas zinc stearate was used as lubricant. The premixed powder mass was compacted at 180ºC by applying 130 kN axial loading and sintered in an inert gas fired sintering furnace at different sintering schedule. The sintered samples were characterized to evaluate their mechanical properties and microstructures. The effect of sintering schedule was studied in terms of mechanical properties, focusing in particular on the relative density, flexural strength and hardness. The microstructure analysis was performed to determine the pore shape, size and distribution. The results revealed that the mechanical properties and microstructures of sintered products were affected by the sintering temperature, holding time as well as the heating/cooling rate.

Social responsibility of organizations has been the most important elements of philosophy, So that it is important to abide by organizations within the social identity theory, Satisfaction of stakeholders outside the organization to legitimate organizations will strengthen. Many of the behaviors and actions of managers and employees, was influenced by moral valuesrooted in ethics. Due to lack of work ethic in management, organizations, societies such as Iran, which was one rich in moral values? The advanced countries have a considerable distance, can create problems for organizations. In addition to increasing the social expectations of organizations, societies, such issues as the environment, women, children, minorities, disabled people, equal employment and staffing reductions, are more sensitive. Organizations ignoring these rights and ethics in dealing with external stakeholders can cause problems for the organization and the organization and action of legitimacy put it, profits, and thus affects the success of the organization. Poor work ethic, the attitude of jobs, organized and effective managers, can affect the performance of individual, group and organizational influence.

The study examined the determinants of consumption of food away from home (FAFH) in the urban sector. The socio-economic characteristics of the respondents and factors motivating it were identified as well as factors that influence the consumption of food away from home. The study used two stage sampling method to select 118 respondents that was used for the study. Data collected were analysed using ordinary least square model. The result revealed that 8 out of the 17 variables considered to influence consumption of FAFH were significant and these are household size, number of children under 6yrs, children between 7 and13years as well as 14 and 17years, total number of visit per week to places for food away from home, number of working female adults and easy access to prepared FAFH. Household size was significant at 1% level and has a direct relationship with household expenditure on consumption of FAFH. The total number of adults present in the household is also significant at 1% and has an inverse relationship with expenditure on consumption of FAFH. Also, the number of children under 6 years is statistically significant at 5% level of significant and it has an inverse relationship with the household expenditure. This could be as a result of specially attention given to young children. Based on the rapid growing trend of consumption of food away from home consumption, this study recommends that FAFH should be taken up by approved and trusted sources putting the health and safety of the consumers into consideration and government agencies concerned with food and health safety should ensure that food served at eateries and restaurants are safe for consumption.

Tin Oxide thin films were deposited by sol gel dip coating method using the acrylamide route. The films were post heated at different temperature in the range of 350-525 ^oC. X-Ray diffraction (XRD) studies indicatyed the formation of tetragonal SnO₂. The Optimum temperature for the formation of the films was 450 ^oC.Microstructural parameters were estimated from the XRD data. XPS studies indicated the peaks corresponding to Sn 3d and 01s. Transmission spectra exhibited interference fringes. Refractive Index was in the range of 2.05-2.18. Optical bandgap value was around 3.68 eV. Three fundamental Raman lines are observed which agree well with that of the bulk material.

A Schiff base namely 3-{4-[4-(Benzylideneamino)benzenesulfonyl]-phenyl}-2-phenylquinazolin-4(3H)-one has been considered here. Theoretical characterization was done by Gaussian-03. The AM1 route has been used. The various parameters such as bond length, bond angle, atomic charge distribution and vibrational frequency analysis have been discussed. The theoretically observed IR values are found to be in accordance with the experimentally obtained values.

In this work we have demonstrated an experimental study and theoretical analysis of the effect of power intensity of illumination on the SnO2/n-Si Hetero-junction devices that irradiated with 150 min. (Cs 137) Gamma ray. The (J-V) characteristic was plotted as function of power intensity of illumination (1.95, 2.88, 3.78, 5.9, and 9.5) mw/cm2. This was shown increase in efficiency of this device until reach maximum efficiency at 9.5 mw/cm2 which represent optimal case. Theoretical analysis of this processes achieve by using “Table Curve 2D version 5.01” program leading to estimate theoretical modeling equation Y= a + b x +c ex We calculate these parameters (a, b, and c) as function of power intensity and testing the equation for power intensity (4 and 8 mw/cm2). Theoretical (J- V) curves are plotted with experimental data, there is a good agreement between them and the behavior of these two curves contain linear term and exponential term.

Listening skills is one of the most fundamental and important skills which can enhance speaking as well as listening skills. However, listening skills has Cinderella skills in language teaching for many years. For FL learners, listening is more difficult than reading. This challenging nature is manifest in Purdy?s (1997, p. 8) definition of listening as “active and dynamic process of attending, perceiving, interpreting, remembering, and responding to the expressed (verbal and nonverbal) needs, concerns, and information offered by other human beings.” The capability to grasp spoken language encompasses complicated, immediate and concurrent processing of various sorts of information. To apprehend spoken language, one is required to organize sounds, vocabulary, grammatical constructions, and prior knowledge (Vandergrift, 1999). Many experts acknowledge the challenging nature of listening (Vogely, 1999; Gonen, 2009).The present study tries to indicate the relevant literature and study about role of transactional and interactional materials on oral productivity.

Effectiveness of library services in the present digital age depends largely upon the application of information and communication technology, with integration into global information initiatives. This paper attempts to explore the impact of globalization on library and information services with emphasis on information environment globally. It is worthy to note that libraries in Africa seems unaffected by globalization and its information driven. It was further observed that African Libraries journeyed to the 21st century is a long and tortuous venture that encompassed with bumps and hiccups. It also analyzed the Nigerian libraries in the era of globalization and concluded by recommending that bold step towards launching Nigerian information environment in the global system becomes not only imperative but a necessity

Compulsive disorder is a cognitive process disorder in which individuals experience ideas, beliefs, imagination and unwanted disturbing impulses that make him/her anxietic and is difficult to remove. The prevalence of OCD is 1/9 to 3/2 percent. With the lifetime prevalence of 2/5 percent and six months prevalance of 1/6 percent, obssessive compulsive disorder is the fourth psychiatric problem in the U.S.A. In Iran, in the region of Kashan, the prevalence of obsessive-compulsive disorder is estimated to be 1 percent. Given the importance of the role of the psychological variables in the causation and the severity of the obsessive – compulsive disorder, the role of perfectionism, worry and responsibility variables has been studied in this research. Recognizing the role of these variables (by psycological methods such as logical thinking, responsibility and worry modification)could help taking an important step treating patients with OCD. The present research is aimed to investigate the prediction of the obssessive – Compulsive disorder, according to the positive and negative perfectionism, worry and responsibility. To achieve this aim ,118 students from ardebil azad university took part in an initial research, completing the positive and negative perfectionim inventory and maudsley obssessional and compulsive inventory (MOCCI), AHWAZ worry inventory(AWI) and responsibility attitude scale (RAS). The spss13 software was used to analyse the datas and the relation between the negative and positive perfectionism and OCD, was evaluated by stepwise regression method. The results of this research showed that the positive perfectionism and worry and resposibility had no role in prediction of the obssessive compulsive disorder.in contrast ,negative perfectionism predicted the obssessive compulsive disorder by stepwise regression method(p<0/05).

The main purpose of this study is to analysis the thermomechanical behavior of the dry contact between the brake disc and pads during the braking phase. The thermal-structural analysis is then used coupling to determine the deformation and the Von Mises stress established in the disc, the contact pressure distribution in pads. The results are satisfactory when compared with those of the specialized literature.
