Multielements in a typical Japanese diet certified reference material prepared at the National Institute for Environmental Studies (NIES) of Japan, in collaboration with the National Institute of Radiological Sciences (NIRS) of Japan were determined by instrumental neutron activation analysis (INAA). Five samples (ca. 510-1000 mg) and comparative standards were irradiated for a short time (10 s...

Teucrium L. is a widely distributed genus often used for the treatment of digestive disorders and respiratory problems. The aim present study was to determine chemical composition essential oils elemental content plant species polium, hircanicum, botrys, chamaedrys, flavum, orientale, scordium Moldovan origin, as well evaluate antimicrobial activity their extracts. determined using gas chromato...

Addition of trace elements (intended or as impurities) in steel or alloys can completely change the properties of materials; thus, there is a necessity to have reliable analytical techniques to determine major and trace components in this type of material. Also, to solving problems with quality control/quality assurance (QC/QA) in this subject, appropriate certified reference materials should b...

gamma-scintigraphy is applied extensively in the development and evaluation of pharmaceutical delivery systems, particularly for monitoring formulations in the gastrointestinal and respiratory tracts. the radiolabelling is generally achieved by the incorporation of an appropriate radionuclide such as technetium-99m or indium-111 into the formulation or by addition of a non-radioactive isotope s...

X-ray fluorescence (XRF) is an established technology for elemental analysis of polyolefins. XRF is a matrix dependent analysis and accurate results require standards of similar matrices. The preparation of blended, matrix-matched polymer standards requires extensive effort and resources. Another quantitative approach is fundamental parameters (FP) analysis, where standards are either pressed p...

BACKGROUND Muscle wasting is a consequence of many primary conditions including sarcopenia, cachexia, osteoporosis, HIV/AIDS, and chronic kidney disease. Unfortunately, there is not a clinically accessible method to measure total body protein, which is the functional mass of muscle. OBJECTIVE We sought to derive a simple method to measure total body protein by using dual-energy X-ray absorpti...

The dissolution of the Soviet Union coupled with the growing sophistication of international terror organizations has brought about a desire to ensure that a sound infrastructure exists to interdict smuggled nuclear material prior to it leaving its country of origin. To combat the threat of nuclear trafficking, radiation portal monitors (RPMs) are deployed around the world to intercept illicit ...
