In the past forty years both participating countries and participants at Summer Deaflympics Games have increased by 2.5-fold. Furthermore, there are approximately fifty European or World sports events organized for hearing impaired. The aim of paper was to discuss procedures requirements related doping control in deaf people’s competitive sport context rising number athletes.For sake fair play ...

Zn doped GaN nanowires with different doping levels (0, <1 at%, and 3-5 at%) have been synthesized through a chemical vapor deposition (CVD) process. The effect of Zn doping on the defect evolution, including stacking fault, dislocation, twin boundary and phase boundary, has been systematically investigated by transmission electron microscopy and first-principles calculations. Undoped GaN nanow...

Many proposed applications of graphene require the ability to tune its electronic structure at the nanoscale. Although charge transfer and field-effect doping can be applied to manipulate charge carrier concentrations, using them to achieve nanoscale control remains a challenge. An alternative approach is 'self-doping', in which extended defects are introduced into the graphene lattice. The con...

In the year 2003, World Anti-Doping Agency (WADA) initiated an international project with the goal to develop a suitable and easy to use software system aimed at the standardized quantitative analysis of digital images acquired during the process of erythropoietin (Epo) doping control. Within the cooperation between Austrian Research Centers GmbH and Institute of Measurement Science, Slovak Aca...

A semiconductor nanocrystal film is a unique class of nanocomposite, whose collective properties are determined by those of its constituents. Colloidal synthetic methods offer precise size control and finely tuned optical properties via quantum confinement, while recent improvements in charge transport through films have led to a variety of optoelectronic applications. However, understanding th...

This paper presents the comparison of two 4.5kV diodes with expanded Safe Operating Area (SOA) in terms of an expansion to higher line voltages. In order to improve the reverse recovery characteristic the excess carrier concentration close to the anode during the on-state has to be reduced. To control the injection efficiency of the anode two state of the art technologies, the reduction of the ...

In racing and other equine sports, it is possible to increase artificially both the physical capability and the presence of a competitive instinct, using drugs, such as anabolic steroids and agents stimulating the central nervous system. The word doping describes this illegitimate use of drugs and the primary motivation of an equine anti-doping policy is to prevent the use of these substances. ...
