Scientists searching for traces of drugs, bomb-making components and other chemicals often shine light on the materials they’re analyzing.This approach is known as spectroscopy, and it involves studyi...
Optimal doping profiles via geometric programming
Doping profile bipolar junction transistor geometrical plan convex optimization breakdown voltage and semiconductors
2015/8/10
We first consider the problem of determining the doping profile that minimizes base transit time in a (homojunction) bipolar junction transistor. We show that this problem can be formulated as a geome...
Relationships between body image,nutritional supplement use,and attitudes towards doping in sport among adolescent boys:implications for prevention programs
Body image Performance-enhancing drugs Image-enhancing drugs Nutritional supplements Doping Male adolescent
2015/7/29
Reports of high levels of use of protein powders and nutritional supplements among young men is a concern because these substances may act as a gateway for the use of drugs and illegal substances to e...
Dietary supplementation and doping-related factors in high-level sailing
Nutritional supplementation Substances Testing design Athlete Coach
2015/7/24
Although dietary supplements (DSs) in sports are considered a natural need resulting from athletes’ increased physical demands, and although they are often consumed by athletes, data on DS usage in Ol...
Promoting functional foods as acceptable alternatives to doping: potential for information-based social marketing approach
Performance enhancing drugs dietary supplements functional foods doping and athletes
2015/7/21
Substances with performance enhancing properties appear on a continuum, ranging from prohibited performance enhancing drugs (PED) through dietary supplements to functional foods (FF). Anti-doping mess...

Sports Nutrition and Doping Factors in Synchronized Swimming: Parallel Analysis among Athletes and Coaches
Dietary supplements reliability validity knowledge
2015/5/19
Although nutrition and doping are important factors in sports, neither is often investigated in synchronized swimming (Synchro).This study aimed to define and compare Synchro athletes and their coache...
Sport Nutrition and Doping in Tennis: An Analysis of Athletes’ Attitudes and Knowledge
Dietary supplementation substances reliability validity test
2015/5/15
Nutrition and doping issues are rarely studied in the sport of tennis. The aims of this investigation were to determine knowledge on doping (KD) and knowledge on sport nutrition (KSN), and correspondi...
Fundamental study of detection of muscle hypertrophy-oriented gene doping by myostatin knock down using RNA interference
In vitro and in vivo transformation C2C12 cultured cell
2015/5/11
To investigate the feasibility of developing a method for detection of gene doping in power-athletes, we devised an experimental model system.
The effects of Co-Ti co-doping on the magnetic,electrical,and magnetodielectric behaviors of M-type barium hexaferrites
materials science barium coercive force doped materials electrical properties ferrites ferroelectric materials magnetic fields magnetic properties magnetization
2016/12/2
Magnetic, electrical and magnetodielectric properties have been studied in Co-Ti co-doped M-type hexaferrite BaCo x Ti x Fe12-2x O19 (x = 0 65 4). With the incorporation of Co-Ti, both their ferromagn...
Formoterol Concentrations in Blood and Urine: The World Anti-Doping Agency 2012 Regulations
