Deterioration of mechanical properties of concrete has been associated to volumetric expansion due to Alkali silica reaction (ASR) and delayed ettringite formation (DEF). This paper investigates the expansion of ASR, DEF and their coupling on the dynamic Young's modulus. The specimens simulated by adding SO3, showed larger expansion and lower dynamic Young's modulus compared to those without SO3 at 20°C and 90°C, however, the effect was more significant and rapid when reactive aggregate was used. ASR may promote DEF to cause the damage when the adequate sulphate is supplied. Keywords: expansion, alkali silica reaction, delayed ettringite formation, dynamic Young's modulus.

By February 2019, thirty million citizens will get Health-Card across Pakistan, which is the best example of E-Health systems becoming popular in Pakistan, said the Minister for National Health Services. However, User E-Readiness (UER) for E-Health (EH) is founded on users' digital literacy and acceptance of digital health services. It also depends on the user perceptions about the problems and prospects of EH. It is assumed that UER determines the success of the EH system in the country and simultaneously reduces the dependence on the traditional healthcare services (THC). Becoming a practical user needs some time to know and use digital gadgets and thereby access online services. This study measures the UER, knowledge, and practices of EH and their current relationship with THC. The Study confirms that UER is significantly and positively related to EH. The study also reveals that there is a significant and negative association between UER and THC meaning that as UER increases, the negative variation happens in THC. Further, demographic impacts of gender are critical with statistics showing that Males are scoring higher on UER and EH, but Females give a higher score on THC. There is a need to increase UER so that EH could be utilized at maximum thereby helping the government in her inability to provide physical healthcare facilities everywhere across the country.

This article assessed the role of Participatory Management in productivity of Iranian Tobacco Company with the help of data envelopment analyses (DEA) in 2016-17. Our research method was descriptive-analytic and comparative. At first Guilan Tobacco Company was selected as accessible sample statistical society among seven provinces that have agricultural, productive and distributive units of tobacco and cigarettes. There are public productive units of an Iranian tobacco company (ITC) and private productive sections that have been set up by the Japan tobacco industry (JTI) in Iranian Tobacco Company. Japan is one of the pioneers in the application of participatory management. The two sections are directed and controlled by the Iranian Tobacco Company. The method of collecting data was through completing questionnaires, Correspondence? Interviews with Managers of different units of Guilan Tobacco Company and then 40 employees were selected as sample society by the accessible method and asked to respond the questionnaires that were contented questions about important indices for three periods, namely before 2009 and 2009-2013 and after 2013periods. Then collected data were analyzed with data envelopment analysis (DEA) method. It showed that rank scores in periods 2009-13 and after 2013 were better than before 2009 periods. The finding confirms that Participatory Management has a role and impact on the productivity of Tobacco Company by mediatory variables.

To determine effect of inoculated roots of seedless white currant grape with three species of Mycorrhizal fungi (Glomus fasiculatu, Glomus intraradices, and Glomus mosseae) on some characteristics including net photosynthesis, stomatal conductance, under-stomatal CO2, photosynthesis rate, amount of chlorophyll, leaf temperature, and leaf's relative water content under drought stress conditions, an experiment was designed in a factorial based on randomized complete block design with four replications. The results indicated that an increase in drought stress led to a reduction in the factors including shoot growth, a number of leaves, leaf level, root dry weight, and shoot dry weight. In comparison with control treatments, inoculation with mycorrhiza fungi had a positive effect on the aforementioned traits so that fungal treatment had the highest effect on chlorophyll index in a leaf of Glomus mosseae fungi. Glomus fasiculatum fungi had the highest positive effect on the index of photosynthesis index. Two Glomus intraradices and Glomus fasiculatum funguses had the most positive effects on the reduction in transpiration rate and sub-stomatal CO2. All three funguses were effective in decreasing leaf area temperature. There was not any significant difference between 25% and 50% irrigation levels under water stress conditions. There was not any difference in CO2, relative water content and transpiration rate at irrigation levels of 50% and 70%.

In the system of economic relations, the labor market occupies an important place. Increasing employment, reducing unemployment and increasing labor productivity is one of the key problems of the transformation of socio-economic relations. In the Russian Federation in 2017 the priority program. Increase of labor productivity and support of employment was approved, however, in the program neither regional, nor gender features of the Russian labor market are taken into account. Therefore, the study examined gender, regional and professional features of the Russian labor market. The main indicators of the labor market are compared with the labor markets of the leading countries. It is revealed that unemployment rates in Russia are higher and labor productivity is lower than in the leading countries. In recent years, there has been an increase in unemployment among the population having University degrees.
For agricultural workers there was a slight decrease, and in the post-crisis year there was a decrease in unemployment (the only category of workers). For the agricultural labor market, a trend was revealed in crisis periods, when the labor markets of other industries are characterized by a slowdown or decline in the growth rate of labor productivity, the growth rate of labor productivity in the agricultural market shows a positive trend. As for other categories of workers there was a sharp increase in unemployment.
The regional feature of the Russian labor market is noted. Despite the overall positive trend the reduction of unemployment in some regions (the Republic of Ingushetia and the Chechen Republic), the unemployment rate remains 3-5 times higher than the Russian indicator. It is proposed to take into account all the identified trends and problems in the development of national projects and programs.

One of the most significant existing environmental problems is the insufficiency of energy produced in the world to meet our energy demand. The renewable energy (RE) resources have become more critical since the majority of the required energy is provided through fossil fuel resources and such resources are exhaustible. The improvement in the availability of RE resources is possible through effective environmental education to the students, who are the future users of such resources. Within the scope of this study, a scale was applied to identify the attitudes and behaviors of university students with different nationalities on the use of renewable energy. The questionnaire used in this research was applied to 500 students of different nationalities, who are studying at the universities located in the northern part of Cyprus in 2015-2016. Multiple basic to specific queries are asked to learn their knowledge, perceptions, attitudes, and behaviors towards RE. The Crosstabs analysis to evaluate the impact on variables. Findings indicate that students from many countries with major resources of fossil fuels, there is a significant need for education for students regarding the necessity of using renewable and green energies. The results showed that Egypt education was more knowledgeable of the uses and the nature of RE technologies.
