UL3703: Standard with regard to Photovoltaic Module Protection Overview: UL3703 masks the safety specifications for photovoltaic (PV) modules and assemblies. It focuses upon ensuring that solar power modules can endure environmental conditions plus operate safely above their intended life-span. Key Points: Mechanised Integrity: Tests with regard to strength against breeze, snow loads, plus mechanical stresses. Power Safety: Ensures proper insulation, grounding, and prevention of electrical risks. Fire Safety: Evaluates the module's weight to fire and ev

The incidence of heart failure (HF) has declined in Europe during the past two decades. However, incidence estimates from registry-based studies may vary, partly because they depend on retrospective searches to exclude previous events. The aim of this study was to assess to what extent different lookback periods (LPs) affect temporal trends in incidence, and to identify the minimal acceptable LP. Further, we wanted to estimate temporal trends in incidence and prevalence of HF in a nationwide population, using the minimal acceptable
