TiO2- and BaTiO3-Assisted Photocatalytic Degradation of Selected Chloroorganic Compounds in Aqueous Medium: Correlation of Reactivity/Orientation Effects of Substituent Groups of the Pollutant Molecule on the Degradation Rate
Investigation of the photocatalytic activity of BaTiO3, a perovskite wideband gap semiconductor has been done in comparison with a widely used photocatalyst TiO2 for the degradation of 4-chlorophenol (4-CP), 4-chloroaniline (4-CA), 3,4-dichloronitrobenzene (3,4-DCNB), and 2,4,5-trichlorophenol (2,4,5-TCP). BaTiO3/TiO2 nanoparticles were prepared by gel-to-crystalline conversion method. BaTiO3 has exhibited better catalytic efficiency and process efficiency compared with TiO2 in most of the cases. The present research focuses mainly on two aspects: first the photocatalytic activity of BaTiO3, as there are very few reports in the literature, and second the reactivity/orientation effects of substituent groups of the pollutant molecules on the degradation rate. The above chloroorganic compounds have at least one chlorine substituent in common, along with other functional groups such as −OH, −NH2, and −NO2. Furthermore, the effect of electron acceptors and pH on the rate of degradation is presented. The reactions follow first-order kinetics. The degradation reaction was followed by UV−vis, IR, and GC-MS spectroscopic techniques. On the basis of the identification of the intermediates, a probable degradation reaction mechanism has been proposed for each compoun

Currently Available Tools and Teaching Strategies for the Interprofessional Education of Students in Health Professions : Literature review
Interprofessional education (IPE) is designed to provide students from different health sectors with opportunities to work together to enhance future collaboration. The implementation of IPE activities is a current trend in various countries. This review exclusively targets IPE issues involving undergraduate health profession students and highlights various approaches in different regions. A total of 28 articles published in peer-reviewed journals between January 2012 and July 2015 were assessed to determine recent trends in IPE implementation. Nine main strategies were identified: simulation-based education programmes; rotations in rural and community settings; interprofessional training wards; patient-centred case studies; theme-centred workshops; student seminars; student-delivered lectures; health promotion activities; and interactive lectures in a common setting. Many of these institutions had not restricted themselves to a single strategy and supplemented these activities with additional teaching or learning methods. Recommendations gathered from these diverse approaches may assist the development of sustainable strategies for implementing IPE in undergraduate medical curricula

Diabetes Mellitus-Related Knowledge among University Students in Ajman, United Arab Emirates
The aim of this study was to assess diabetes mellitus (DM)-related knowledge and practices among university students enrolled in non-health care related professional courses in the United Arab Emirates. Methods: A pre-tested questionnaire assessing the knowledge of DM was administered to the above-mentioned students. Data collected were transferred to PASW Statistics (Chicago, IL, USA, Version 18) and analysed. Results: Data on 168 university students (47 males and 121 females) were included in the analysis. Of the participants, 25% were overweight or obese and only 27% exercised regularly. Regarding their knowledge of DM, 70% knew that it is characterised by high blood sugar levels and identified family history as a major risk factor. Surprisingly, only just over half could link obesity and physical inactivity as risk factors for developing DM, or could identify an excessive feeling of thirst, frequent urination, and weight loss as symptoms. Knowledge of the complications of diabetes, including gangrene, loss of sensation in limbs, oral and dental complications, recurrent infections, and risk for cardiovascular disease got a moderate response. Knowledge of diabetes was found to be higher in females compared to males. No significant differences were observed in the health behaviour of participants with or without a family history of DM. Conclusion: Our study revealed that in spite of exposure to various sources of information, the participants’ level of DM-related knowledge was not adequate. We recommend the engagement of health professionals in educational settings in order to enhance health-related knowledge and inculcate healthy lifestyle practices in students.
