Performance testing of dosimeters used in interventional radiology: Results from the VERIDIC project
(Radiation Measurements, 2021)
Interventional procedures in radiology and cardiology are associated with high dose to the patient. Accurate dosimetry is essential and calibration of the equipment is a means to provide the necessary accuracy of dose ...
Investigation of xenon-filled tube breakdown voltage and delay response as possible dosimetric parameters for small gamma ray air kerma rates
(Radiation Protection Dosimetry, 2020)
This paper presents experimental results of dynamic breakdown voltage and delay response as functions of gamma ray air kerma rate for xenon-filled tube at 2.7 mbar pressure. Gamma ray air kerma rate range was considered ...
The role of external and internal mass transfer in the process of Cu2+removal by natural mineral sorbents
(Environmental Technology, 2011)
The kinetics of Cu2+ sorption on to zeolite, clay and diatomite was investigated as a function of initial metal concentrations. For consideration of the mass transfer phenomena, single resistance models based on both film ...
Analysis and comparison of mass transfer phenomena related to Cu2+ sorption by hydroxyapatite and zeolite
(Chemical Engineering Journal, 2013)
Zeolite and hydroxyapatite (HAP) are well-known sorbent materials, with high capacities for removal of toxic heavy metals. In this study, the influence of process parameters onto kinetics of Cu2+ sorption by zeolite and ...
Amendment Type and Dose Effects onto Coexisting Copper, Lead, and Nickel Ions Distribution in Soil
(Water, Air, and Soil Pollution, 2018)
The use of soil additives for toxic metals chemical stabilization aims to decrease in situ the pollutants’ mobility and availability. In this study, the effectiveness of rinsed red mud (RBRM) and annealed animal bones ...
Analysis of Factors Influencing Cu(II) Sorption By Clinoptiolite
(Hemijska industrija, 2013)
Experimental design methodology represents a powerful tool for the analysis and optimization of various processes. Immobilization of toxic substances by sorption onto low-cost materials has gained a lot of attention in the ...
The influence of equilibration conditions and hydroxyapatite physico-chemical properties onto retention of Cu2+ ions
(Chemical Engineering Journal, 2009)
The influence of equilibration conditions and hydroxyapatite (HAP) physico-chemical properties onto retention of Cu2+ ions was studied in batch conditions. The amount of cation removed from the solution increased with ...
Influence of Aggregate Type on the Properties on SCC with Fly Ash
(International RILEM Conference on Synergising Expertise towards Sustainability and Robustness of Cement-based Materials and Concrete Structures, 2023)
This study compared the performance of self-compacting concrete (SCC) based on fly ash addition and limestone filler. A SCC prepared with Portland cement, river sand, and limestone filler was used as a reference sample. ...
Establishing a priori and a posteriori predictive models to assess patients’ peak skin dose in interventional cardiology. Part 2: results of the VERIDIC project
(Acta Radiologica, 2021)
Optimizing patient exposure in interventional cardiology is key to avoid skin injuries.PurposeTo establish predictive models of peak skin dose (PSD) during percutaneous coronary intervention (PCI), chronic total occlusion ...
Binuclear Co(II) complexes with macrocycle and carboxylato ligands: structure, cytotoxicity and thermal behavior
(Journal of Molecular Structure, 2021)
In vitro cytotoxic evaluation, formation constants and thermal stability of four mixed-ligand Co(II) complexes with tpmc = N,N',N",N'"-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane and carboxylate/dicarboxylate ...
