Abstract
The discussion of climate policy received new impetus in the spring of 2019. Since then the topic has dominated the public discourse in Germany. The Fridays for Future movement continues to generate considerable pressure on policy makers. In addition, scientists emphasize in rare interdisciplinary unanimity both how urgent a radical renewal in climate policy would be, and that a uniform price for greenhouse gas emissions is the indispensable core element of the necessary reforms in Germany and Europe. One central aspect of climate policy is, however, often overlooked in all this: climate protection is essentially an international problem of cooperation. For climate change, it does not matter where greenhouse gases are emitted. The success of national climate policy must therefore be judged by whether it contributes to establishing international cooperation to reduce global greenhouse gas emissions.

Abstract
A facile synthesis of undoped and 2.0 % selenium-doped zinc oxide nanoparticles (NPs) was efficaciously accomplished through a mechanochemical route using zinc acetate dihydrate, oxalic acid, and Se powder in a solid state reaction. After calcination at 450 °C, the obtained nanostructures were probed by X-ray diffraction, where the acquired data revealed the pertinence of the wurtzite hexagonal ZnO for both undoped (ZnO) and doped (Se/ZnO) NPs and crystallite sizes of 30 and 24 nm for ZnO and Se/ZnO, respectively. The formation of the target NPs was confirmed by the scanning and transmission electron microscopy, energy-dispersive X-ray analysis, and the Fourier transformation infrared molecular vibrations data. The porosity investigations indicated 33.65 m2/g Brunauer–Emmett–Teller surface area, 197 Å pore diameter, and 0.172 cm3/g pore volume for the Se/ZnO NPs compared to lower values for the pristine ZnO. The band gap energies were 3.19 and 3.15 eV for ZnO and Se/ZnO as perceived from the Tauc plots of the UV-visible absorption measurements. The photodegradation of methylene blue dye under UV illumination was found to follow the pseudo–first-order kinetics with an enhanced performance by the doped samples as reflected by the higher (3.2 × 10−3 s−1) rate constant relative to the undoped sample (1.7 × 10−3 s−1). A photodegradation mechanism was suggested in the light of the band gap energy investigation. The obtained findings indicate the improvement of ZnO properties by doping with Se through a simplistic and inexpensive approach.

Published: September 2019

Abstract
A simple and rapid method for the preparation of benzopyranophenazines is presented, involving a one-pot four-component reaction of hydroxynaphthoquinone, o-phenylenediamine, benzaldehydes, and malononitrile with nano-Fe3O4@chitosan as an efficient heterogeneous solid acid catalyst under reflux conditions in ethanol. The catalyst is characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), magnetic susceptibility measurements, energy-dispersive X-ray spectroscopy (EDS), and Fourier transform infrared (FT-IR) spectroscopy. Atom economy, high catalytic activity, a wide range of products, excellent yields in short reaction times, and low catalyst loading are some of the important features of this method.

Abstract
Recently, Wang et al. (Z. Wang, J. Ha, Y. H. Kim, W. B. Im, J. McKittrick, S. P. Ong, Joule
2018, 2, 914–926) predicted and discovered Sr2LiAlO4, a quaternary compound with a layered structure crystallizing in the monoclinic space group P21/m, and they refined the structure from PXRD data. Upon partially substituting strontium with europium, the substance exhibits a yellow broadband luminescence consisting of two overlapping emission bands. In this paper, the crystal structure of Sr2LiAlO4 is confirmed by additional SC-XRD measurements and a newly discovered polymorph of Sr2LiAlO4 is presented crystallizing in the orthorhombic space group Cmcm. When Eu2+ is incorporated, this polymorph exhibits only one of the emission bands present in the P21/m-polymorph. Additionally, two substitutional variants of Sr2LiAlO4 are presented along with their luminescence properties upon incorporating Eu2+. One with a partial substitution of strontium for barium, leading to a structure in space group Pnma, and one with a partial substitution of oxygen for nitrogen, exhibiting the structure in space group Cmcm. The structure-property relationships in the above mentioned compounds are discussed with regard to their luminescence performance.

Use of different external mediating mechanisms of the Bohr atom model: Evidence of Meaningful Learning through verbal-gestural analysis in elementary school students
Authors: Freitas Savana Dos Anjos , Serrano Agostinho 
Published: September 2019

The present article sought to investigate if the use of different external mediation mechanisms to teach the Bohr Atom model in elementary education with the didactic methodology of the Potentially Significant Teaching Units (PSTU) can result in Meaningful learning. Therefore, we naturally use the theoretical contribution of the Ausubelian Meaningful Learning Theory, in particular by discussing elements that indicate evidence of meaningful learning. This theory was adopted with the purpose of understanding and analyzing whether or not there is evidence of meaningful learning with elementary level students after about a year of using the didactic methodology. The didactic methodology used was the application of didactic sequences inspired by the PSTU model, modified to be applied in Elementary School. We also use different external mediation mechanisms that independently reproduce the Bohr atom model, such as model building (psychophysical mediation), teacher explanation on a blackboard (social mediation), use of textbooks (cultural mediation) and computer simulations (hypercultural mediation). Data analysis was carried out through two semi-structured interviews according to the Report Aloud protocol followed by the depictive gestural analysis, performed with an interval of almost one year, both interviews were carried out after the application of the didactic methodology, in order to assess the retention of the learning residue. We argue that the students' verbal-gestural production indicates that there was meaningful learning of the Bohr Atom model, especially related to social and hypercultural mediations.

Published: September 2019

A 39-year-old man referred to us with a complaint of dyspnea and palpitation of 3 days’ duration. The patient was tachycardic but normotensive with a normal blood oxygen saturation level of about 91%. His electrocardiogram showed a sinus rhythm with an incomplete right bundle branch block. There was no known risk factor for vein thrombosis in his past medical history. Transthoracic and then transesophageal echocardiography revealed a large, hypermobile elongated mass (about 10×1 cm) in the right atrium. The mass was in transit through a large patent foramen ovale (Figure 1, Video 1). There was also severe right ventricular dilation with moderate systolic dysfunction on echocardiography, suggestive of pulmonary thromboembolism (PTE). Consequently, multiple-detector computed tomography angiography was performed to determine mortality risk and help the decision-making regarding the duration of anticoagulation therapy. The angiographic procedure revealed massive bilateral PTE (Figure 2).
The patient was referred for atriotomy and pulmonary embolectomy on cardiopulmonary bypass (Figure 3).
A thrombus in transit is a life-threatening, albeit rare, type of right-heart thrombosis with mortality rates of 80-100% in untreated patients,1 necessitating urgent assessment and treatment. A thrombus in transit can result in catastrophic systemic embolism in a patient with PTE; therefore, taking heed of this issue in the presence of a right atrial mass is of great therapeutic significance. Meticulous imaging modalities in such patients are mandatory to prove the existence of a patent foramen ovale with a view to deciding on an emergent individualized therapeutic management of the patient’s condition.

Abstract
Background WeChat in China has been used for public health education and the prevention of diseases. This study introduced a WeChat-based program for rabies prevention and evaluated the users’ satisfaction with the program using the technology acceptance model.Methods An online satisfaction questionnaire was used to survey 315 users who had followed the WeChat official account in China, and their satisfaction scores were assessed and analyzed.Results The users were generally satisfied with the WeChat-based program as an educational and instructional tool with the mean satisfaction score for each item ranging from 3.87 to 4.60 out of a maximum of 5.0 and the total mean satisfaction score of 41.54 out of a maximum of 50.0 (SD = 4.31). Urban users showed more satisfaction than rural users (p=0.031). Users who were satisfied also reported that they intended to recommend WeChat to others (p= 0.000).Conclusions Findings from the present study indicated that WeChat was considered a useful educational and instructional tool for rabies among dog-bite victims. This model of a WeChat-based program for rabies prevention should be expanded to other areas in China.

Abstract
Background: Dengue fever is a rapidly emerging vector born infectious disease caused by Dengue virus and it is now one of WHO reportable diseases. About 50 -200 million cases, 20,000 deaths occur annually. In Ethiopia the first outbreak of Dengue fever appeared in Dire Dawa city in 2013, where 9441 cases were recorded. The second Dengue fever outbreak occurred in Afar Region. Third and fourth was in Somali Region in Godey town, 2014 and 2015. In Godey town acute febrile illness cases of unknown cause become increased started from May 27, 2015. We investigated to identify risk factors of Dengue fever outbreak and commence control measures. Methods: A case-control study was conducted in Godey town, Ethiopia from 8-22 July 2015. Cases were defined according to the WHO guideline and controls were individuals with no sign and symptoms living in the same town with cases. We recruited 50 cases and 100 controls in the study. Medical records and line lists were reviewed. Data were collected at household level using structured questionnaires. Twenty-four serum samples collected from cases. Data was analyzed using SPSS 20 software. Result: We identified 223 cases with 0 death, 116 (52%) were male. The mean age of cases was 25.8 years. Ten cases were positive for Dengue fever by PCR at national laboratory. Lack of formal education (AOR=3.1; 95%CI: 1.30-7.49), living with ill person (AOR=2.8; 95%CI: 1.22-6.52), open containers in household (AOR=3.6; 95%CI: 1.34-9.38) and presence of larvae in the water containers (AOR=5.4; 95%CI: 2.33-12.44) were risk factors for the outbreak. Conclusion: Poor household water handling, living with ill person and lack of formal education contributes for occurrence of Dengue fever outbreak in Godey town. Health education and all other interventions associated with use of water and sanitation needs to be part of long-term control of Dengue.

Abstract
Background To verify the prevalence and profile of users and non-users of anabolic steroid (AS) among resistance training practitioners. Methods: An observational, cross-sectional prevalence survey was performed in 100 gyms in Curitiba city, involving 5773 individuals and self-administered questionnaires. . The chi-square and z-tests of proportions (p<0.05) were used for analysis. Prevalence ratio according to sex and age was calculated using the Poisson regression model (p<0.05). Results: 83.2% did not use, 9.1% formerly used, 3.4% currently used, and 4.3% intended used AS. The prevalence of former or current AS users was 16.9% and 6.5% among men and women, respectively. The prevalence ratios were as follows: 1) 2.6 male users for each woman; 2) 3.3 individuals aged 30-44 years and 2.8 individuals aged 18-29 years for each individual aged over 45 years. Beginners were not interested in using AS, but individuals who had trained longer had higher prevalence of AS use. Conclusions: The gym environment encouraged the use of AS owing to aesthetic appeal. Thus, suggesting the need for actions to prevent abusive use of AS considering the practitioners profile.

Abstract
Background

Informed dietary choices during childhood is necessary for building good eating habits in the present and future generations. There is a significant increase globally in trends of over nutrition, specifically, overweight and obesity among school children in Africa calls for consideration of home and school environments.

Methods

A systematic literature search was conducted between October to December 2018 using Medline (PubMed), Directory of Open Access Journals and Google Scholar databases. Also, a grey literature review was conducted to identify and retrieve relevant documents and reports some of which from websites of international organizations. Major topics of interest were home and school food environments, dietary choices, school children and Africa. Out of 318 articles 30 were included in the full text read after meeting the inclusion criteria such as focusing on school children in Africa. Four reports from grey literature were also included. This review includes articles published between the 1st January 2008 and 30th June 2018.

Results

Available data from reviewed articles showed that obesity prevalence among school children in Africa is on the rise and ranges from less than 5% to more than 30% across countries. Few articles investigated the contribution of home and school environments on school children’s food choices which necessitates more research in this area.

Conclusion

Therefore, this review suggests that for effective implementation of childhood overweight and obesity reduction strategies, investigation of home and school determinants of children’s food choices is imperative.
