    Glyfosaat in stedelijk oppervlaktewater

    Get PDF
    Veel gemeentes en bedrijven gebruiken chemische onkruidbestrijdingsmiddelen (herbiciden) voor de bestrijding van onkruid op verhardingen. Door afspoeling van hemelwater komt een deel van het gebruikte glyfosaat in het oppervlaktewater terecht. Dit kan leiden tot piekconcentraties in het stedelijk oppervlaktewater. Omdat er nog maar weinig meetgegevens van glyfosaat in stedelijk water beschikbaar zijn, hebben de Gelderse waterschappen samen met vier gemeenten gedurende de zomer van 2009 een indicatieve meetcampagne uitgevoerd naar de aanwezigheid van glyfosaat in het stedelijke oppervlaktewater. Hierbij zijn verrassend hoge concentraties glyfosaat aangetroffen

    ABSTRACT: Motivation for teaching is key in the establishment and further development of high-quality higher education, as it affects teachers’ investment in quality learning experiences for their students, as well as institutional efficacy and well-being. This study aimed to validate a questionnaire, originally developed in Belgium, designed to evaluate three dimensions (self-efficacy, interest, and effort) of intrinsic motivation for teaching for a different national population. The sample consisted of 616 academics working in public higher education institutions in Portugal. Confirmatory factor analysis was conducted and internal consistency of items analyzed. The results show that the original dimensionality of the construct is confirmed in the Portuguese teachers’ sample. Motivation for teaching in the Portuguese context is primarily explained by the following factors: personal efficacy, interest in the task, and effort placed on teaching responsibilities. A difference was found in that personal efficacy could not be divided in context and general personal efficacy.RESUMO: A motivação para ensinar é fundamental para o desenvolvimento de ensino superior de qualidade, pois determina o investimento dos professores em experiências de aprendizagem de qualidade para os seus estudantes, bem como a eficácia e bem-estar institucionais. O estudo teve por objetivo a validação de um questionário, originalmente desenvolvido na Bélgica, destinado a avaliar três dimensões (autoeficácia, interesse e esforço) sobre motivação intrínseca para ensinar, para uma população nacional distinta. A amostra é composta por 616 acadêmicos que trabalham em instituições públicas de ensino superior em Portugal. Realizou-se a análise fatorial confirmatória e analisou-se a consistência interna dos itens para cada uma das dimensões avaliadas. Os resultados mostram que a dimensionalidade original do constructo é confirmada na amostra portuguesa, sendo a motivação para o ensino explicada principalmente pelos seguintes fatores: eficácia pessoal, interesse pelo trabalho e esforço nas responsabilidades de ensino. Não foram encontradas diferenças entre eficácia pessoal geral e eficácia pessoal contextual.RESUMEN: La motivación para la enseñanza es clave en el desarrollo de una educación superior de calidad, porque determina la inversión de los profesores en experiencias de aprendizaje de calidad para sus estudiantes, así como la eficacia institucional y el bienestar.

    This report presents the results of measurements performed at one animal facility for veal calves using the control-case approach, to estimate the ammonia and odour emission reduction of a floor (Groene Vlag) combined with a V-shaped manure belt under the floor compared to the traditional wooden slatted floor. These measurements were commissioned by Bettink Service Team and by Beerepoot Stalinrichtingen BV. Ammonia emissions were significantly lower (53%) than the emission from the traditional floor measured simultaneously within the same farm (case-control approach). Odour emissions were significantly lower (47%) than the emission from the traditional floor measured simultaneously within the same farm (case-control approach)

    Long-term cardiac follow-up of athletes infected with SARS-CoV-2 after resumption of elite-level sports

    OBJECTIVE: Longitudinal consequences and potential interactions of COVID-19 and elite-level sports and exercise are unclear. Therefore, we determined the long-term detrimental cardiac effects of the interaction between SARS-CoV-2 infection and the highest level of sports and exercise.METHODS: This prospective controlled study included elite athletes from the Evaluation of Lifetime participation in Intensive Top-level sports and Exercise cohort. Athletes infected with SARS-CoV-2were offered structured, additional cardiovascular screenings, including cardiovascular MRI (CMR). We compared ventricular volumes and function, late gadolinium enhancement (LGE) and T1 relaxation times, between infected and non-infected elite athletes, and collected follow-up data on cardiac adverse events, ventricular arrhythmia burden and the cessation of sports careers.RESULTS: We included 259 elite athletes (mean age 26±5 years; 40% women), of whom 123 were infected (9% cardiovascular symptoms) and 136 were controls. We found no differences in function and volumetric CMR parameters. Four infected athletes (3%) demonstrated LGE (one reversible), compared with none of the controls. During the 26.7 (±5.8) months follow-up, all four athletes resumed elite-level sports, without an increase in ventricular arrhythmias or adverse cardiac remodelling. None of the infected athletes reported new cardiac symptoms or events. The majority (n=118; 96%) still participated in elite-level sports; no sports careers were terminated due to SARS-CoV-2.CONCLUSIONS: This prospective study demonstrates the safety of resuming elite-level sports after SARS-CoV-2 infection. The medium-term risks associated with SARS-CoV-2 infection and elite-level sports appear low, as the resumption of elite sports did not lead to detrimental cardiac effects or increases in clinical events, even in the four elite athletes with SARS-CoV-2 associated myocardial involvement.</p

    Sampling and contaminant monitoring protocol for raptors

    Get PDF
    In May 2013 representatives from six countries gathered in Murcia, Spain, to attend the Workshop on &ldquo;Setting best practices on raptor contaminant monitoring activities in Europe&rdquo; funded by EURAPMON. The workshop developed a rough draft of the current protocol. The protocol was subsequently completed with the involvement of investigators from Belgium, Denmark, France, Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom. All contributors are experts in monitoring contaminants in raptors. The aim of this sampling protocol is to provide guidance on types of best practice that will facilitate harmonisation of procedures between existing and emerging schemes and so maximise the reliability, comparability and interoperability of data.The methods here do not require use of anaesthesia on birds. This protocol covers the sampling of blood and feathers from live birds, addled and deserted eggs, internal organs and tissues from dead specimens, and other samples such as faeces, preen oil and pellets.</p

    IntroductionThe low prevalence of Arterial Thoracic Outlet Syndrome (ATOS) and diffuse symptomatology have resulted in limited data on optimal treatment strategies and long-term outcome. The aim of this study was to report and evaluate a single center experience with the treatment of ATOS including midterm patient reported outcome.MethodsAll patients treated for ATOS from 2004 to 2020 were retrospectively identified. Patients were divided into two groups based on presenting symptoms; ATOX group (Acute arterial occlusion with ischemia) and ATOS group (claudication symptoms). Baseline characteristics and treatment details were extracted from electronic patient files. A telephone survey was conducted to collect patients' follow-up data including a functional disability score using the Quick Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. The primary endpoint of this study was symptom-free survival. Secondary endpoints were median QuickDASH scores during follow-up, postoperative complications and possible re-interventions.ResultsA total of 20 patients (mean age 44.6 years, median follow-up 50.5 months) were included and divided into two groups (ATOX N = 9, ATOS N = 11). In the ATOX group, eight patients were primarily treated with catheter directed thrombolysis (CDT; N = 5) or surgical thrombectomy (N = 3). All patients received staged thoracic outlet decompression surgery (TOD). In the ATOS group, 10 patients primarily received TOD and one patient was treated conservatively with physiotherapy. Seven ATOX patients and nine ATOS patients were symptom free at follow-up with a median QuickDASH score of 2.3 (IQR 12.5) and 2.3 (IQR 16.5) respectively. Ten complications occurred in the ATOX group; three bleeding complications, five re-occlusions, one arterial dissection and one occipital infarction. In the ATOS group five complications occurred; one perioperative bleeding complication, three re-occlusions and a stent fracture. Seven vs. five re-interventions were required in the ATOX and ATOS groups respectively.ConclusionThe mid-term self-reported symptom free survival in both the ATOX as well as ATOS group seems acceptable while median QuickDASH scores in both groups indicate a very good functional outcome. This however comes at the cost of treatment related bleeding complications in especially the ATOX group presumably due to thrombolysis, and re-interventions required in almost one out of three patients

    Defining the industrial and engineering management professional profile: a longitudinal study based on job advertisements

    Get PDF
    The engineering professional profiles have been discussed by several branches of the engineering field. On the one hand, this discussion helps to understand the professional practice and contributes to the specification of the competences that are suitable for each function and company culture. On the other hand, it is an essential starting point for the definition of curricula in engineering schools. Thus, this study aims to characterize, in an innovative way based on job advertisements, the demand for competences and areas of practice for Industrial Engineering and Management contributing for the definition of a professional profile. This characterization is based on the analysis of 1391 job advertisements, collected during seven years from a Portuguese newspaper. The data analysis takes into account the job description in which two categories were considered: areas of professional practice (e.g. project management) and transversal competences (e.g. teamwork). Considering the total number of job advertisements, it was possible to identify 1,962 cumulative references for 11 professional practice areas and 5,261 cumulative references for transversal competences. The contribution of this study lies on the identification of the main areas of practice and the main transversal competences demanded by employers.This work was partially funded by COMPETE-POCI-01-0145-FEDER-007043 and FCT-UID-CEC-00319-2013
