Time changes of dose equivalent rate above the soil surface as indication of natural attenuation processes [PDF]
Proceedings of the International Association of Hydrological Sciences, 2019 Eight sites in the Fukushima contaminated area were surveyed for long-term changes in D-shuttle dose equivalent rate above the soil surface during 2015–2017. D-shuttle readings in most cases decreased faster than if due to radioactive decay only.

Efficiency calibration of a well-type HPGe detector using experimental and Monte Carlo simulation techniques [PDF]
Nuclear Technology and Radiation Protection, 2020 Well-type high-purity germanium detectors are well suited for the analysis of small samples, as they combine high detection efficiency with low background radiation. The well geometry however makes efficiency calibration more difficult than that

Brain delivery of vasoactive intestinal peptide (VIP) following nasal administration to rats [PDF]
, 2003 The aim of this work was to study in rats the nasal route for the brain delivery of the vasoactive intestinal peptide (VIP) neuropeptide. After evaluating VIP stability in solutions obtained from nasal washes, the effect of formulation parameters (pH 4-9,

Generation of nanoparticles in the concentrated energy (laser beam) and gas flow
Aviation, 2004 The method of generation and selection of small nanoparticles in the airflow is considered in this paper. To melt the material (stainless steel), a concentrated energy flow – a pulsed solid‐state laser beam – was used.

The neglected activation of tantalum in reduced activation materials
Nuclear Materials and Energy, 2023 Due to the expression of “reduced activation”, the severe radioactivity of tantalum (Ta) after neutron irradiation in early decay years is easily neglected. In the presented study, after an irradiation of only 0.3 dpa by fission neutron and followed by a

FEBS Letters, EarlyView.Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...
