SULFATE REDUCTION AND RELATED STABLE ISOTOPE ( 34 S , 18 O ) VARIATIONS IN INTERSTITIAL WATERS FROM THE EASTERN MEDITERRANEAN

Interstitial waters from eleven sites of the Eastern Mediterranean Basin (Sites 963–973) were analyzed for stable isoto dissolved sulfate ( δ34S, δ18O) and major and minor ions. Sulfate reduction rates are positively related to bulk sedimentation rates, which indicates a higher burial of metaboliz organic matter with increasing sedimentation rates. Bacterial sulfate reduction in the deeper samples from most of the s superimposed by a sulfate input from Messinian evaporites or late-stage evaporite brines that are located at depth; dissolu of gypsum within the cored section was found at Sites 967 and 968. Authigenic gypsum precipitation was identified at Site below 100 mbsf. Intense sulfate reduction is also indicated for the pore waters from the mud volcanoes of Sites 970 and 971. In additi high concentrations of hydrocarbons (mainly CH 4), coexisting H2S and SO4 2– were also present, indicating that methane percolates through the sediment from greater depths. The observed variabilities in sulfate concentrations between different holes of Sites 970 and 971 are caused mainly by locally varying-upward fluxes of methane. Extremely high alkalinity values in the pore waters of Sites 970 and 971 are the result of microbial CH4 oxidation. The concentration and sulfur isotopic composition of pore-water sulfate (δ34S values up to +112 ‰ vs. the Vienna-Canyon Diablo troilite standard) are dominated by microbial organic matter degradation with associated sulfate reduction. There most interstitial fluids are enriched in 34S with respect to modern Mediterranean seawater ( δ34S = +20.7‰; Site 973 surface seawater). δO(SO4) values at Site 963 and 964 are also enriched in 18O with respect to Mediterranean seawater (δO[SO4 ] = +9.4‰). δ34S and δ18O values of dissolved residual sulfate are positively related to each other. An initial kinetic isotop effect is superimposed by oxygen isotope exchange reactions leading to an increased equilibration between residual sulfa pore water with increasing degree of sulfate reduction. It is suggested that δ18O−δ34S relations of residual sulfate directly reflect sulfate reduction rates in marine sediments.
The effect of home care services on maternal health after cesarean delivery in Turkey

Back ground: Cesarean delivery is one of the most common surgical procedures performed today in Turkey. Maternal death after cesarean delivery is rare. However, more maternal problems arise after cesarean delivery compared to vaginal delivery. Therefore, it is very important for the nurses to make home visits to the women who can not properly benefit health services due to early postpartum discharge. The present research was conducted in order to determine the effect on maternal health of home care services given to the women who were discharged from hospital 96 hours after cesarean delivery. Methods: This randomized control study consisted of 140 women (intervention group=70, control group=70) who resided in Middle Anatolia, Turkey. Three home visits were made on the 2nd, 15th and 42nd postpartum days after discharge of the women in the intervention group. Care and training was given to the women during these visits. There was no intervention for women in the control group. Results: A statistically significant difference was found in favor of the intervention group in terms of health problems during the 6-week postpartum period. Conclusions: The research indicated that nurses’ planned home visits to women discharged early from hospital following birth by cesarean delivery affected mother’s health positively.

Hydrogen-bonded water in laumontite II: Experimental determination of site-specific thermodynamic properties of hydration of the W1 and W5 sites

Abstract Isothermal vapor sorption experiments under controlled partial pressures of H2O (between 0.1 and 30 mbar, at 23.4, 30.1, 49.5, 64.5, and 79.3 °C) and liquid water immersion calorimetry experiments at 25.0 °C were conducted to determine standard molar thermodynamic properties of hydration of the W1 and W5 sites in laumontite that host hydrogen-bonded water. A Langmuir adsorption model was used in a thermodynamic analysis of the isothermal adsorption data for the W5 site together with a symmetrical regular solution model. Resulting values for the standard molar Gibbs energy and entropy of hydration of the W5 site relative to liquid water are -8430 ± 113 J/mol and -16.7 ± 2.1 J/(mol·K), respectively, and the Margules parameter, WG, is 1590 ± 63 J/mol. The standard enthalpy of hydration of the W1 site was determined by liquid-water immersion calorimetry experiments on laumontite containing vacant W1 and fully occupied W5, W2, and W8 sites. Discontinuous hydration and dehydration of W1 at 23.4 ± 0.7 °C and 24 ± 1 mbar PH₂O was used to constrain the molar Gibbs energy of hydration of this site. Resulting values for standard molar Gibbs energy of hydration and enthalpy of W1 relative to liquid water are -380 ± 170 and -8800 ± 1150 J/ mol, respectively. Isothermal adsorption at 23.4 °C and isobaric thermogravimetric experiments indicate that during dehydration of W1, only 0.83 moles of water are released from the crystal structure and 0.17 moles are relocated to a disordered site that has energetic properties similar to the W8 site. Calculations using the thermodynamic data determined in this study indicate that the water content of laumontite in equilibrium with liquid water ranges from ~4.5 H2O per 12 framework O atoms at room temperature and one bar pressure to ~3.5 H2O at 250 °C and at liquid-vapor saturation pressure for water.
Speciation of Heavy metals by modified BCR sequential extraction in soils contaminated by phosphogypsum in Sfax, Tunisia

The accumulation of trace metals in soil is a serious environmental problem that creates a hazard when metals are transferred to water or plants. To understand the mobility and bioavailability of trace metals, the concentrations and distributions of trace metals must be established for different physical and chemical phases of the soil. We determined the concentrations of trace metals (Zn, Pb, Cu, Cr, Co, Ni, Mn, and Fe) in soil using the sequential extraction method recommended by Community Bureau of Reference (BCR) and analysed chemical properties, such as the pH, cation exchange capacity, total organic carbon, electrical conductivity, and calcium carbonate. Our results revealed higher concentrations of trace metals in topsoil samples (0–20 cm) than in subsoil samples (20–40 cm and 40–60 cm) for most metals at four sites. Zn in the topsoil was mostly associated with the non-resistant fraction at all sites. Approximately 60% more Pb was bound to the non-residual, exchangeable and reducible fractions at all sites, and soil depths. Cr, Cu, Ni and Fe were mainly in the residual fraction, whereas Mn was largely present in the non-resistant fraction. The global contamination factor of trace metals decreased with soil depth. The mobility and bioavailability were greatest for Zn, followed by Cu and Pb. DOI: http://dx.doi. org/10.5755/j01.erem. 70.4. 7807
A study of views of Facebook users on the role of haptics in social network systems

UNIVERSITY OF TAMPERE Department of Information Studies and Interactive Media LEPPÄNEN, EVA: A Study of Views of Facebook Users on the Role of Haptics in Social Network Systems M.Sc. thesis, 83 pages, 6 appendix pages Information Studies and Interactive Media September 2010 The research area relates to mediated interaction and people’s activities in social network systems of the Internet. There are various systems available in the Internet for mediated social interaction. The context of this research is limited to voluntary and free-time based social interaction and maintenance of personal relationships. The purpose is to clarify the role of haptics (the sense of touch) as a part of activities of social network systems. Since the question is about social interaction occurring at free-time and concerning mundane matters, it makes sense to think about means for enriching the interaction with more affective, playful, supportive, and interactive ways, although people are already able to adapt and use the prevalent text-based interaction in various ways. Also, increasing mobile use of social network systems creates new contexts and challenges to be faced for making mobile use fluent. In addition, mediated interaction creates new affordances for communicating and being in contact with others. Because of changing behavior and new interaction contexts, there might be needs for additional and alternative means of interaction. Mediated haptics might be a viable alternative since the sense of touch is an important part of physical interpersonal interaction and has a role in making interaction more affective and personal. The subject is future oriented. The results of the user study are based on knowledge of contemporary technology and usage of social network systems, which presumably will develop in parallel with development of haptic solutions. Consequently, this research serves as an initial overview on the subject at this moment of time when Facebook use has achieved mass use, and only a few haptic solutions are commercially obtainable. The research concentrates on Facebook and similar social network systems. A user study was conducted in order to clarify views of users on usage of haptics. A semi-open questionnaire was selected as the method. As a part of the questionnaire, three different scenarios involving haptics were provided to the participants for evaluation. Based on the results obtained, it could be concluded that Facebook is not used in such a way that would benefit much from haptics. At least, users are not yet ready for bigger changes and are relatively satisfied with the current usage. However, the user study together with theoretical analyses revealed potential usages of haptics in the future and matters to be considered in designing haptic solutions. In addition, different development paths are proposed for inclusion of haptics: one as an enhancement to messaging and another associated with interaction in 3D environments and gaming.

Presentation of the Extended Technology Acceptance Model in Sports Organizations

Background. In recent decades, information technology has become a vital component of various aspects of our lives. The use of information technology in different domains has made the analysis of the level of its acceptance/rejection a significant factor in organizations. Objectives. The aim of this study was to illustrate the application of the extended technology acceptance model in sports organizations. Methods. The participants consisted of 350 employees selected from across various Iranian sports organizations. The data were collected according to the perceived ease of use, perceived usefulness, attitude (AT), intention to use (IU), technology self-efficacy (TSE), technology anxiety, perceived enjoyment, and user satisfaction for each variable in the study model. A panel of experts determined the face and content validity of the experiment. The Cranach’s alpha coefficient was used to determine the validity. Results. The results showed that AT, self-efficacy, PU, EOU, and user satisfaction have a meaningful effect on the intention to use information technology. The highest effect was related to AT, and the lowest to user satisfaction. Conclusion. It can be claimed that when people have a more positive AT toward the use of information technology, they will exhibit beliefs or excitements, which makes it more viable for them to perceive information technology positively, and consequently increase the intention to use it.
Examination of influences of cultural dimensions on threecomponents of career commitment in Dutch and Chinese cultures

There is no doubt that the issue of career commitment has drawn great attention from both scholars and managers in the last two decades. This could be explained partially by the fact that organizational commitment is considered as a predictor of turnover and work-related behaviors, such as performance, absenteeism, and organizational citizenship (Meyer & Allen, 1991). To correctly and effectively use commitment to predict and produce desired behaviors, it is important to first understand the nature of commitment, and the variables serving as antecedents of commitment. Moreover, with increasing globalization in the modern societies, many companies attempt to expand their business overseas to different markets in different cultures, and it is a common phenomena that these international companies recruit local employees from the local labor markets. Arguably, without the knowledge about the antecedent variables of career commitment, predicting and generating desired behaviors could be even more difficult concerning a cross-culture workforce. Thus, it is reasonable to state that for both theoretical and practical purposes, the study of the antecedents of career commitment on the cultural level is necessarily important, and it suggests that this current research should be derived from both theoretical relevant and practical relevant bases.
Fitness aerobics as a means of recovery the physical capacity of young volleyball players (boys and girls)

Introduction. Improving the results in sports involves applying loads with significant volumes and intensity. It requires the introduction into the system of preparation of a complex of recovery the physical capacity. The study put forward the hypothesis that the use of fitness aerobics as a means of recovery will positively affect the level of functional capabilities, general and special physical fitness of volleyball players 16-17 years old. Aim of Study. The purpose of the work is to experimentally substantiate the use of fitness with elements of aerobics as a means of recovery physical performance in the training process of volleyball players of 16-17 years (boys and girls). Material and Methods. The study involved athletes engaged in volleyball at The Dvorichansky youth and children’s club of physical training “Youth” of the Kharkiv region, in the number of 30 boys and 30 girls (age 16-17 years). Both teams are silver winners of the championship of the Kharkiv region volleyball season 2016-2017 years. The study was conducted from September 2016 to May 2017. During nine months during the regenerative periods, athletes were engaged in fitness with elements of aerobics with a fitness trainer. Duration of lessons was 40 minutes. Lessons were held 2 times a week in the last week of each month. Results. It is established that it is advisable to organize muscular activity, taking into account its directed influence on the body, that involves management of physical capacity and recovery processes. It has been shown that for athletes of 16-17 years of age, it is necessary to use special recovery cycles with a wide inclusion of recovery means with the transition to other types of physical exercises. The effectiveness of the dosed monthly application of aerobics as a means of restoring the efficiency of young volleyball players is substantiated. The developed method positively influences both girls and boys. However, under the influence of the developed technique, the girls improve their recovery. This can be explained by the fact that girls are more emotional, so the use

The dependent variables used in this research are return on assets (ROA), return on equity (ROE) and return on capital employed (ROCE). The study adopted descriptive and explanatory research design. Also this study used a cross sectional and time series data collection approach that was analysed using E-views software. The observation of 260 firms/years was selected using simple random sampling. The collected data was analyzed using descriptive means, Pearson correlation and multiple linear regression via E-views. Regression analysis was employed in examine the impact and influences of WOB. Thus, the findings shows that NWOB, PWOB and NFNED has significant relationship on ROA, ROE and ROCE, except found insignificant relationship between PWOB and ROA. Besides, variables PWOB and NFNED has positive impact on the three measure; ROA, ROE and ROCE but has negative impact from NWOB on the three financial measure. The uniqueness of this paper that the study of NFNED and ROCE as few research only done in this relationship. This show the remarkable of this study as the relationship show positively significant for Malaysia’s Public Listed Companies. Although this study included only 52 companies, future studies may include larger sample by conducting more organizations and sectors and might re-examine the insignificant relationship between PWOB and ROA.
Using a shared L1 to reduce cognitive overload and anxiety levels in the L2 classroom

This paper considers the attitudes and behaviours of university language lecturers and their students regarding the use of the L1 in the higher education L2 classroom. A case study of one Irish higher education institution was carried out and qualitative interviews conducted with six lecturers in Japanese and six in German. The results indicated widespread support among the participants for the judicious use of the L1 in limited instances, particularly where it can facilitate a reduction in cognitive overload and learner anxiety by, for example, the explanation of complex terminology, concepts and grammatical structures, as well as aiding in the creation of a relaxed classroom environment. Implications for the language classroom and for this field of research are considered.
