The determination of trace rare-earth elements (REEs) can be used for the assessment of environmental pollution, and is of great significance to the study of toxicity and toxicology in animals and plants. N, N, N', N'-tetraoctyl diglycolamide (TODGA) is an environmental friendly extractant that is highly selective to REEs. In this study, an analytical method was developed for the simultaneous d...

The aim of the study was to compare the two reference methods for the determination of boron in water samples and further assess the impact of the method of preparation of samples for analysis on the results obtained. Samples were collected during different desalination processes, ultrafiltration and the double reverse osmosis system, connected in series. From each point, samples were prepared ...

Abstract The large-scale adoption of occupational exoskeletons (OEs) will only happen if clear evidence effectiveness the devices is available. Performing product-specific field validation studies would allow stakeholders and decision-makers (e.g., employers, ergonomists, health, safety departments) to assess OEs’ in their specific work contexts with experienced workers, who could further provi...

The paper presents possibilities and difficulties in nondestructive analysis of small multielement single crystals performed by means of X-ray spectrometry techniques: micro-X-ray fluorescence spectrometry (μ-XRF), energy-dispersive electron probe microanalysis (ED-EPMA), and X-ray photoelectron spectroscopy (XPS). The capability of the X-ray spectroscopy techniques in elemental analysis is dem...

In the present paper, the elemental composition of wood ashes obtained by the combustion of wood in a fireplace was determined with the use of ICP-MS and ICP-OES techniques. Wood ashes may find a potential application as deacidifying agents and soil conditioners, since they contain calcium (in the form of CaCO(3) and CaO), potassium (in the form of K(2)SO(4) and K(2)CO(3)) and significant level...

In Arabidopsis thaliana, acyl-CoA-binding proteins (ACBPs) are encoded by a family of six genes (ACBP1 to ACBP6), and are essential for diverse cellular activities. Recent investigations suggest that the membrane-anchored ACBPs are involved in oxygen sensing by sequestration of group VII ethylene-responsive factors under normoxia. Here, we demonstrate the involvement of Arabidopsis ACBP3 in hyp...

The radiation from the arc plasma ignited between flat ends of copper electrodes in atmospheric pressure air at a direct current 3.5 A is analyzed to determine temperature and composition. Side-on spectra range (430 – 650) nm are recorded using CMOS camera connected spectrograph. spectral emission coefficient evaluated radiance, which provides radiator number density. excitation obtained by app...

one of the chapters in the history of iranian music is the place and significance of the musical instrument called oud. this instrument, initially named “barbat”, emerged during the sassanid dynasty. generally known under the name “oud” in islamic era, it became grepopular in islamic countries. in iran, this instrument enjoyed great importance until the fall of the safavid dynasty. from the ear...

In forensic toxicology, precise determination of toxic trace metals in biological samples is critical. Inductively coupled plasma optical emission spectrometry (ICP OES), which has a low limit detection, high sensitivity, accurate testing, and analytical efficiency, one the most widely used techniques for determining level samples. This study aimed to assess efficiency ICP-OES estimating cadmiu...

The Occupational Employment Statistics (OES) Survey is a yearly mail survey designed to produce estimates of employment and wages for more than 700 occupations in the U.S. The OES sample is stratified by geographic area, economic activity, and employment size class; with geographic area defined by State, Metropolitan Statistical Area (MSA) and balance of State area, and economic activity define...
