This paper presents a new concept for an active high voltage insulation system with dynamic and adaptive features. The governing principle is based on surface charge accumulation on dielectrically covered electrodes in air under atmospheric pressure. This accumulation results in a charge-induced electric field component which steers the field distribution within the system advantageously. At eq...

OBJECTIVE To compare the thermal environment of infants who died of the sudden infant death syndrome with that of age matched control infants. DESIGN Case-control study. Infants who died were matched with two controls, one for age and one for age and birth weight. Thermal measurements were conducted at the death scene for cases and at the scene of last sleep for control infants, who were visi...

During on an extensive investigation of a multi-story timber building with light-frame construction, several stages of the building process and their impact on sound transmission were observed. The sound insulation properties of the building components were measured before and while the buildings were occupied. Furthermore, interviews with the occupants were conducted. This procedure made it po...

This study is devoted to the possibility of using advanced insulation materials, such as Vacuum Insulation Panels (VIP), in and reconstruction buildings, connection with green elements that are installed on facade case use external thermal composite systems (ETICS). The VIP part system will result a significant reduction required thickness layer. In turn, reduced overall allow for easier direct...

To satisfy the fast-growing electricity demand, high-voltage power systems with higher performance and better stability are required, which raises challenges including design of systems, control high-power electronics, synthesis preparation high-performance insulation materials, evaluation conditions, dielectric tests, material modification, environment protection, etc [...]

Recent studies on the transcriptional regulation of two linked, imprinted genes, Igf2 and H19, have provided evidence for a novel mechanism of epigenetic control. DNA methylation controls the activity of an insulator element located between the two linked genes by regulating the binding of the zinc-finger protein CTCF.

Un-accurate modeling of power system may cause to under or over-design the insulation, which in turn, leads to increase in the investment and/or maintenance cost of the network protection against lightning overvoltages. The grounding system is an effective parameter on the magnitude of the lightning overvoltages and insulation coordination of high voltage transmission lines (TLs). This paper pr...
