An introduction to the models which are usually applied, when interpreting the NMR (nuclear magnetic resonance) parameterKnight shift (Ks) and spin-lattice relaxation rate 1/T1 in the normal and the superconducting state of high-temperature superconductors, is given. The different hyperfine interacti...

In 2000, the Naval Medical Research Center Detachment (NMRCD) and the Ministry of Health of Peru established a passive surveillance study to determine arboviral causes of febrile illness (protocol NMRCD.2000.0006). Venezuelan equine encephalitis and 2 human deaths, Peru Patients with acute, undiffer...
2019年1月18日至19日， 2019年全国生态环境保护工作会议在京召开。生态环境部部长介绍道，2018年，蓝天保卫战全面推进。全国338个地级及以上城市平均优良天数比例为79.3%，同比上升1.3个百分点。三大重点区域——京津冀及周边地区、长三角、汾渭平原的PM2.5浓度分别为60微克/立方米、44微克/立方米、58微克/立方米，...
If the file extension or signature does not match the file format, errors will occur when opening or editing the file. When there is a problem with a file, the first step to solving it is to determine the file format. In the following you will find our evaluation of the PROJ files: ...
How does EPR work? EPR is a magnetic resonance technique very similar to NMR (Nuclear Magnetic Resonance). However, instead of measuring the nuclear transitions in our sample, we are detecting the transitions of unpaired electrons in an applied magnetic field. Like a proton, the electron has “...
Neilsen is a privately-owned U.S. company with a history dating back to the early 1920s. It continues as it began, a company that researches and measures interactions between audiences and media. Many types of companies and investors use its data to try to determine consumer trends. ...
