Correction of stray magnetic fields caused by cable currents is essential for human in-vivo brain magnetic resonance current density imaging (MRCDI)

Accurate mapping of current flows in the human brain is important for many neuroscientific applications. MRCDI is an emerging method, which combines MRI with externally applied alternating currents to derive current flow distributions based on measurements of the current-induced magnetic fields. However, inaccurate and inconsistent measurements occur unless the stray magnetic fields ca used by the currents flowing in the feeding cables are corrected [1] . Here, we explore the influences of the stray magnetic fields due to the cable - currents in realistic experimental MRCDI set - ups

Cultural variations in the relationship between anger coping styles, depression and life satisfaction

Hypotheses are tested that ways of handling anger and their consequences will differ in student samples drawn from dignity cultures (UK and Finland), honor cultures (Turkey and Pakistan) and face cultures (Hong Kong and China). In line with our hypotheses, holding anger in and controlling anger correlate positively in face cultures but not in other samples, whereas holding anger in and letting anger out correlate positively in honor cultures but not in other samples. Furthermore, holding anger in and letting anger out are more strongly predictive of high depression and low life satisfaction in honor cultures than in other samples. The results provide support for the cross-cultural validity of Spielberger's (1999) anger expression inventory and for the proposition that differences in ways of handling anger can be understood in terms of contrasting cultural contexts

Nation-level moderators of the extent to which self-efficacy and relationship harmony predict students’ depression and life satisfaction: evidence from ten cultures

Previous two-nation comparisons have provided evidence that self-efficacy may be a protective factor against depression in individualist cultures, whereas relationship harmony may be a stronger protective factor in collectivist cultures. However, wider sampling and more specific measures of cultural difference are required to test these conclusions. Student ratings of depression and life satisfaction were surveyed in 10 samples drawn from nine nations. Culture-level individualism positively moderated the relationship of self-efficacy to low depression. However, culture-level collectivism negatively moderated the linkage of relationship harmony to depression. To better understand these effects, four separate nation-level predictors derived from dimensions of self-construal were employed. Effects of self-efficacy were strongest where cultural models of selfhood emphasized self-direction (vs. receptiveness to influence); effects of relationship harmony were strongest where cultural models of selfhood emphasized dependence on others (vs. self-reliance). These results illustrate the value of unpackaging the diffusely defined concept of individualism-collectivism

Recent advances in the reduction of nitro compounds by heterogenous catalysts

Amines which are organic molecules can be employed in several significant syntheses such as the synthesis of biologically active molecules, polymers, drugs, dyes and pharmaceutical products. The critical issue in the synthesis of amines is to choose the most efficient heteregenous catalyst in order to obtain the best catalytic activity, reusability and durability. For this purpose, up to know, many studies have been performed on the reduction of nitro compounds to synthesize amines in the presence of various heteregenous catalysts. Addressed herein, recent developments have been gathered on the production of amines by the help of heteregenous catalysts such as platinum-, gold-, palladium-, silver-, nickel-, iron-, copper-, ruthenium-, iridium-, rhodium-, ionic liquid- and carbon-based monometallic, bimetallic and multimetallic heterogenous catalysts. Those catalysts have showed superior characteristics in terms of the amount, recoverability, reusability and the structural integrity of catalyst during the reaction. Thus, the main goal of this study is to enlighten the scientists and to discuss (review) the critical investigations on the reduction of nitro groups by heterogenous catalysts in last years. © 2017 Bentham Science Publishers.2015-35, 2015-50, 2014-05 2015.05.03.333, 2014.05.03.243 Academy of Health SciencesThe authors would like to thank to Duzce University (grant no.2015.05.03.333 and 2014.05.03.243) and Dumlupinar University Research Fund (2014-05, 2015-35 and 2015-50).
