Empowering Studentsâ Learning Achievement Through Project-Based Learning As Perceived By Electrical Instructors And Students
Purposes of this research were to find out factors empowering electrical studentsâ learning achievement through Project-Based Learning (PBL) as perceived by instructorsâ and studentsâ opinions. The sample chosen for this study were 247 electrical power instructors at vocational education institutes and 161 electrical students in the 3 rd and 4th year who were studying in the 1st semester of academic year 2006 at Electrical Education Department, Faculty of Industrial Education and Technology, King Mongkutâs University of Technology Thonburi by using simple random sampling. The instrument used for data collection was 7 rating scales questionnaire. The reliability of the instrument calculated by Cronbach Alpha Coefficient was 0.8185 and 0.9839, respectively. The data were analysed by using mean ( ), Standard Deviation (S.D.) and Analysis of Factors by Principal Component Analysis technique: PCA, orthogonal rotation axis by Varimax Method. The results of the study on factors empowering electrical studentsâ learning achievement through Project-Based Learning (PBL) were as follows: both instructors and students agreed on Interesting/Attention(0.799 and 0.885, respectively) while other factors such as Planning(0.722), Sharing Ideas(0.582), Thinking(0.576), Facilitating (0.547), Constructionism (0.540), Scientific Process (0.525), Multiple Intelligence (0.479), and Goal Setting(0.453) were perceived by instructors, and studentsâ opinions were on Advising/Guiding(0.863), Thinking(0.661), Goal Setting (0.634), Multiple Intelligence(0.553), Scientific Process(0.528), Assisting(0.524), and Sharing Ideas (0.492), if not more so
Pelagic seabirds as biomonitors of persistent organic pollutants in the Southwestern Atlantic
Persistent Organic Pollutants (POPs) are accumulated through time and can exert different effect on ecosystems. POPs and Chlorpyrifos, a current use pesticide, were assessed in body feathers of males and females of Black-browed albatross (Thalassarche melanophris, BBA) and Cape petrels (Daption capense, CAP) during their non-breeding seasons at the Patagonian Shelf, Argentina. Chlorpyrifos showed the highest values among all pollutants in both species (49.56â84.88 ng gâ1), resulting from current agricultural practices. The pattern OCPs > PCBs > PBDEs was observed in both species, and CAP showed higher concentrations than BBA probably as a consequence of higher lipid mobilization and pollutants availability during dispersion. Non-significant differences between sexes about POPs levels were found; however a slight tendency was observed, females>males in CAP, and males>females in BBA. More attention and further studies are needed to understand seabirds' physiology and its relationship with the pollutants distribution in their tissues and considering breeding season.Fil: Quadri AdroguĂ©, Agustina.

GAPS-megacities: A new global platform for investigating persistent organic pollutants and chemicals of emerging concern in urban air
A pilot study was initiated in 2018 under the Global Atmospheric Passive Sampling (GAPS) Network named GAPS-Megacities. This study included 20 megacities/major cities across the globe with the goal of better understanding and comparing ambient air levels of persistent organic pollutants and other chemicals of emerging concern, to which humans residing in large cities are exposed. The first results from the initial period of sampling are reported for 19 cities for several classes of flame retardants (FRs) including organophosphate esters (OPEs), polybrominated diphenyl ethers (PBDEs), and halogenated flame retardants (HFRs) including new flame retardants (NFRs), tetrabromobisphenol A (TBBPA) and hexabromocyclododecane (HBCDD). The two cities, New York (USA) and London (UK) stood out with âŒ3.5 to 30 times higher total FR concentrations as compared to other major cities, with total concentrations of OPEs of 15,100 and 14,100 pg/m, respectively. Atmospheric concentrations of OPEs significantly dominated the FR profile at all sites, with total concentrations in air that were 2â5 orders of magnitude higher compared to other targeted chemical classes. A moderately strong and significant correlation (r = 0.625, p < 0.001) was observed for Gross Domestic Product index of the cities with total OPEs levels. Although large differences in FR levels were observed between some cities, when averaged across the five United Nations regions, the FR classes were more evenly distributed and varied by less than a factor of five. Results for Toronto, which is a âreference cityâ for this study, agreed well with a more in-depth investigation of the level of FRs over different seasons and across eight sites representing different urban source sectors (e.g. traffic, industrial, residential and background). Future sampling periods under this project will investigate trace metals and other contaminant classes, linkages to toxicology, non-targeted analysis, and eventually temporal trends. The study provides a unique urban platform for evaluating global exposome.A global study across 20 megacities/major cities reporting urban air concentrations of flame retardants and plasticizers.Authors thank the United Nations Environment Programme

Stress echo 2020: The international stress echo study in ischemic and non-ischemic heart disease
Abstract
Background
Stress echocardiography (SE) has an established role in evidence-based guidelines, but recently its breadth and variety of applications have extended well beyond coronary artery disease (CAD). We lack a prospective research study of SE applications, in and beyond CAD, also considering a variety of signs in addition to regional wall motion abnormalities.
Methods
In a prospective, multicenter, international, observational study design, > 100 certified high-volume SE labs (initially from Italy, Brazil, Hungary, and Serbia) will be networked with an organized system of clinical, laboratory and imaging data collection at the time of physical or pharmacological SE, with structured follow-up information. The study is endorsed by the Italian Society of Cardiovascular Echography and organized in 10 subprojects focusing on: contractile reserve for prediction of cardiac resynchronization or medical therapy response; stress B-lines in heart failure; hypertrophic cardiomyopathy; heart failure with preserved ejection fraction; mitral regurgitation after either transcatheter or surgical aortic valve replacement; outdoor SE in extreme physiology; right ventricular contractile reserve in repaired Tetralogy of Fallot; suspected or initial pulmonary arterial hypertension; coronary flow velocity, left ventricular elastance reserve and B-lines in known or suspected CAD; identification of subclinical familial ..
