The research objective of the project and article “European Ecological Network Natura 2000 – opportunities and threats” Natura 2000 sites constitute a form of environmental protection, several legal problems are likely to result. Most controversially, certain sites will be subject to two regimes of protection: as national parks and as Natura 2000 sites. This dualism of the legal regulation make...

Shunt capacitor banks are used to improve the quality of the electrical supply and the efficient operation of the power system. Studies show that a flat voltage profile on the system can significantly reduce line losses. Shunt capacitor banks are relatively inexpensive and can be easily installed anywhere on the network. This paper reviews principles of shunt capacitor bank design for substatio...

The threat from unpredictable influenza virus pandemics necessitates the development of a new type of influenza vaccine. Since the internal proteins are highly conserved, induction of T cells targeting these antigens may provide the solution. Indeed, adenoviral (Ad) vectors expressing flu nucleoprotein have previously been found to induce short-term protection in mice. In this study we confirm ...

Abstract: Nowadays, the use of distributed generation (DG) has increased because of benefits such as increased reliability, reduced losses, improvement in the line capacity, and less environmental pollution. The protection of microgrids, which consist of generation sources, is one of the most crucial concerns of basic distribution operators. One of the key issues in this field is the protection...

introduction: open-apex teeth with irreversible pulpitis require complex and difficult treatment. providing the right environment for apexogenesis and pulp protection is vital for their long term prognosis. the young pulp of open apex tooth, however, is better equipped against irritation and assault. the aim of this study was to evaluate pulp inflammation in open apex canine teeth of cats. mate...

1,1-diacetates(acylals) were prepared by direct condensation of various aldehydes with acetic anhydride using dipyridine cobalt chloride (copy2cl2) as an efficient and green catalyst under solvent-free conditions at room temperature. the important features of this catalyst method are that the catalyst is solid, stable at high temperatures, soluble in water, stable in air, immiscible in common o...

Encapsulation of hemoglobin (Hb) within a liposome is one of the strategies in the development of artificial oxygen carriers. In this study the effects of oxygen radical generating system (xantine/xantine oxidase) on the internal microviscosity and protein degradation of hemoglobin-containing liposomes ('hemosomes') prepared from dipalmitoylphosphatidylcholine (DPPC) and different amounts of ch...
