From the variation of magnetic properties with temperature trans-bis[ 1,2-bis(diethylphosphino)ethane]di-iodochromium(ii) undergoes a sharp S = 2 to S = 1 spin-state transition between 165 and 175 K.

Objectives: This study aimed to assess the impact of the Gross Domestic Product (GDP), spending on Research and Development (R&D), the number of universities and scientific journals on the published research documents, citable documents, citations per document and H-index in environmental sciences in the Middle East countries. Materials and Methods: All the 16 Middle East countries were included in the study. Information regarding the GDP, spending on R&D, the total number of universities and indexed journals was collected. Total number of research documents (papers), citable documents,

Objective: To explore the impact of auditory integrative training (AIT) on the inflammatory biomarker transforming growth factor (TGF)-β1 and to assess its effect on social behavior in children with autism spectrum disorder (ASD). Subjects and Methods: In this cross-sectional study, 15 patients (14 males and 1 female) with ASD aged 3-12 years were recruited. All were screened for autism using the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Plasma levels of TGF-β1 were measured in all patients using a sandwich enzyme-linked immunoassay (ELISA) immediately and 1 and 3 months after the AIT sessions. Pre- and post-AIT behavioral scores were also calculated for each child using the Childhood Autism Rating Scale (CARS), the Social Responsiveness Scale (SRS), and the Short Sensory Profile (SSP). Data were analyzed using the Statistical Package for the Social Sciences (SPSS 21.0 for Windows). Results: Plasma levels of TGF-β1 significantly increased to 85% immediately after AIT (20.13 ± 12 ng/mL, p < 0.05), to 95% 1 month after AIT (21.2 ± 11 ng/mL, p < 0.01), and to 105% 3 months after AIT (22.25 ± 16 ng/mL, p < 0.01) compared to before AIT (10.85 ± 8 ng/mL). Results also revealed that behavioral rating scales (CARS, SRS, and SSP) improved in terms of disease severity after AIT. Conclusion: Increased plasma levels of TGF-β1 support the therapeutic effect of AIT on TGF-β1 followed by improvement in social awareness, social cognition, and social communication in children with ASD. Furthermore, TGF-β1 was associated with severity in all scores tested (CARS, SRS, and SSP); if confirmed in studies with larger sample sizes, TGF-β1 may be considered as a marker of ASD severity and to assess the efficacy of therapeutic interventions.

This paper and the associated presentation will describe the latest developments regarding alkaline anion-exchange membrane (AAEM) fuel cells at Surrey. The program of work conducted has been targeted at the materials development of both membranes and electrodes containing alkaline ionomers and as such has focused on H 2 /O 2 fuel cell testing. Radiation-grafted AAEMs can be made with fully hydrated thicknesses between 18 -80 µm with conductivities in water of up to 0.06 S cm -2 at 60°C. A peak power density of 230 mW cm geo -2 and a maximum current density at full discharge of 1.3 A cm geo -2 have been obtained in a H 2 /O 2 fuel cell at 50°C with a 18 µm AAEM and Toray carbon paper based electrodes (Pt/C(20%mass), 0.5 mg Pt cm geo -2 loading) that were treated with Surrey's first generation alkaline ionomer. A future priority is the development of the next generation alkaline ionomer.
