Журнал Белорусского государственного университета: Химия, 2019 Nandrolone is an anabolic androgenic steroid. The use of this substance is prohibited by World Anti-Doping Agency (WADA). In National Anti-Doping Laboratory, we have developed method for quantitative determination of major nandrolone metabolite – 19 ...

Effect of Zn doping on magnetic order and superconductivity in LaFeAsO [PDF]
, 2009 We report Zn-doping effect in the parent and F-doped LaFeAsO oxy-arsenides. Slight Zn doping in LaFe$_{1-x}$Zn$_{x}$AsO drastically suppresses the resistivity anomaly around 150 K associated with the antiferromagnetic (AFM) spin density wave (SDW) in the

Intraplanar couplings in the CuO_2 lattice of cuprate superconductors [PDF]
, 2004 We have investigated the doping dependencies of the basal areas in single-layer high-T_c cuprates La_{2-x}Sr_xCuO_4 and HgBa_2CuO_x, as well as in two-layer Y_{1-y}Ca_yBa_2Cu_3O_x and HgBa_2CaCu_2O_x.

Using the prototype willingness model to predict doping in sport. [PDF]
, 2014 To enable preventive measures to be designed, it is important to identify modifiable distal and proximal factors underlying doping behavior. This study investigated aspects of the prototype willingness model in relation to doping. A cross-sectional study

European Journal of Applied Physiology, 2010 It is with great interest that we read exchanges on intermittent hypoxic (Boning 2009; Ferretti 2009) exposure as a potential doping procedure. Erythropoietin (EPO) does introduce potential concerns in terms of doping, both due to its eVects and side eVects. An earlier publication on exogenous EPO (Noakes 2008) clearly showed an increase of sub-maximal

Survival of the d-wave superconducting state near the edge of antiferromagnetism in the cuprate phase diagram [PDF]
, 2003 In the cuprate superconductor $YBa_2Cu_3O_{6+x}$, hole doping in the $CuO_2$ layers is controlled by both oxygen content and the degree of oxygen-ordering.
