A method was developed to determine the concentration of uranium (238U) in urine. This involved preconcentration from urine with calcium phosphate neutron activation followed by simple radiochemical separation. Using this method, it possible detect 0.2 ng 238U. The average and geometric mean found subjects a normal background environment 12.8 9.4 L-1, respectively. daily intake same population used arrive at gastrointestinal absorption factor (f1) for incorporated diet. f1 estimated be 1.6%.
Analysis of hearts patients dying from endomyocardial fibrosis showed a significantly greater concentration cerium, lanthanide present in leafy vegetables and root tubers, than control hearts. This may be important the pathogenesis disease provides geographical basis for prevalence tropics.

Abstract The dynamics of dense crowds have received considerable attention from researchers seeking fundamental understanding or aiming to develop data-driven algorithms predict pedestrian trajectories. However, current research mainly relies on data collected in controlled settings. We present one the first comprehensive field datasets describing at different scales, contextualized macroscopic crowd flows over hundreds meters microscopic trajectories (around 7000 individual trajectories)....
A method involving neutron activation followed by simple radiochemical separation was developed and applied to determine the concentrations of Th in blood serum urine. The is sufficiently sensitive detect 0.025 ng 232Th. average concentration found urine subjects from normal environments 7.9 L-1 2.7 L-1, respectively.
Within the framework of a Coordinated Research Project (CRP) organized by International Atomic Energy Agency, Vienna, daily dietary intakes seven elements adult populations living in nine Asian countries were estimated. The that participated study Bangladesh, China, India, Indonesia, Japan, Pakistan, Philippines, South Korea (Republic Korea, ROK), and Vietnam together they represented more than half world population. studied calcium, cesium, iodine, potassium, strontium, thorium, uranium....
In a search for geochemical factors that could play role in the pathogenesis of tropical endomyocardial fibrosis, tissue samples obtained from patients at necropsy or operation were analysed major elements present laterite and monazite, which are important soil constituents Kerala State India. Atomic absorption spectrophotometry was used detecting iron, silicon, aluminium, zinc, magnesium, calcium, sodium, potassium, manganese neutron activation analysis thorium. Compared with control...
Recent data-driven approaches using neural networks have shown promising results for pedestrian trajectory prediction. These algorithms outperform the knowledge-based and physics-based models in terms of distance error. However, it has been observed that produce too many collisions overlaps, leading to unrealistic predictions. To address this problem, we propose contribution a hybrid extension Social-LSTM approach by introducing collision loss training. The is provided an interaction energy...
A Certified Reference Material (CRM) was prepared at the National Institute for Environmental Studies (NIES), Japan, in collaboration with of Radiological Sciences (NIRS), analytical quality assurance minor and trace elements food related matrixes. The starting material CRM all served 29 households Japan over two 3-day periods 1997-1998, thus represented a typical Japanese diet. All foods (meals, snacks, beverages) were homogenized, freeze-dried, pulverized, blended, dispensed into 1,100...
This organ burdens of uranium were estimated for an urban Indian (Bombay) population living in a normal background environment, using the technique neutron activation analysis, combination with post-irradiation chemical separation. The total were: skeleton > muscle soft tissue lungs kidney liver heart. A comparison was made between observed skeleton, kidney, and those obtained by applying metabolic model as recommended International Commission on Radiological Protection (ICRP) to its daily...
