Production of monodisperse uranium oxide particles and their characterization by scanning electron microscopy and secondary ion mass spectrometry
2000
Abstract Secondary ion mass spectrometry (SIMS) can be confidently used to measure uranium isotopic ratios in single particles. Dense particles of known isotopic composition and size allow the precision and the accuracy of the applied procedure to be estimated. These particles can be obtained by dissolving standard reference uranium materials, nebulizing the solution in droplets of proper diameter and collecting the particles after the desolvation and calcination of the droplets. A new instrumental set up, based on a commercial vibrating orifice aerosol generator to generate monodisperse droplets of the solutions from four uranium oxide reference materials, is described. The droplets were d…
Ikääntyvien opiskelu ja koulutus
1994
Right up to the present, study by the elderly has focused mainly on general adult education. Consequently, marginalisation in this area has been particularly harmful to this section of the population, the people who have received the least education in our society. The motives and points of departure concerning the elderly have not yet been clearly formulated in adult education. This state of affairs is exemplified by the facts that adult education policy statements almost entirely by-pass the issue of education for the elderly and that an educational policy aimed at the elderly simply does not exist. The elderly can no longer be expected to be satisfied with mere activities for the sake of…
Eclecticismo en la intervención con adolescentes en conflicto con la ley
2014
El trabajo social, como disciplina científica, se dota de marcos conceptuales que son derivados de otras ciencias sociales que legitiman y avalan su práctica profesional. A lo largo de su historia, ha ido produciéndose enfoques conceptuales y modelos teóricos que dirigen la intervención profesional con la finalidad de abordar, eficazmente, la pluralidad de problemáticas y demandas sociales que integra su ámbito de actuación. En el presente artículo, se exponen aquellos esquemas referenciales cuya aplicación resultan particularmente fructíferos en la intervención con adolecentes en conflicto con la ley en el ámbito nacional. En consecuencia, se describen y contrastan los principales modelos,…
Visual defects in subjects with Down’s syndrome
1995
Because the incidence of other visual defects is much higher in cases of Down’s syndrome than in individuals with other forms of retardation (Gardiner, 1967; Aitchison et al., 1990), we tested the color vision of a population of Down’s syndrome patients, using Ishihara plates and the Davico anomaloscope. The Down’s syndrome group had a significantly higher proportion of color deficiencies than either normal controls or a matched mentally retarded population. Refractive errors were corrected with static retinoscopy, and spatial contrast sensitivity was measured with the Vistech test.
Bounded Rationality for “Just In Time” Education
2011
Abstract If you cannot get answers keep putting questions The paper has three targets: a) Taken per se , it advances the research presented in a series of seven papers about education in a post-industrial (i.e., service-oriented) society broadening the scope from engineering to any kind of education reachable through reachable through permanent endeavour. b) Regarded as part of a “EU 2020 research cluster” with the aim to pro pose affordable approaches to education for sustainable development, the paper reveals bounded rationality (BR) as common denominator of, mechanism for, and connection between the two facets of permanent education: e- teaching and e- learning , the research aiming to m…
On the Absence of Direct Effect of the WTO Dispute Settlement Body's Decisions in the EU Legal Order
2012
This chapter talks about the Absence of Direct Effect of the WTO Dispute Settlement Body's Decisions in the EU Legal Order. It covers five main sections: (1) The Domestic Validity and Rank of Decision (2) Their Internal Effects (3) The 'Scope for Manoeuvre' Argument: An Assessment from the Perspective of the WTO Legal System (4) The 'Scope for Manoeuvre' Argument: An Assessment from the Perspective of the EU Legal System and (5) The Pragmatic Role Played by Direct Effect in the Protection of the Autonomy of the EU Legal Order and Its Costs. According to established case law, while the binding character of international agreements is sufficient to use WTO law as a standard for reviewing the …
Phosphotungstic acid (PTA) in the synthesis of 3D CdS superstructures by diffusion assisted hydrothermal method
2015
Abstract In this study, the synthesis of cadmium sulfide (CdS) microstructures by gas diffusion assisted hydrothermal method using phosphotungstic acid (PTA) is reported. The as-synthesized products were characterized by Fourier transform infrared (FTIR), powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). The effects of PTA dose, thioacetamide amount, time and temperature on the morphology of obtained particles have been studied. In this process, PTA ion host stabilizes the CdS particles against aggregation and thioacetamide plays two roles, being at the same time a sulfur source and a capping ligand. Based on the performed analyses it seems that the thioacetamide is mor…
The Use of Electron Microscopy and Stereology in the Study of the Mammalian Pineal Gland
1983
Now that transmission electron microscopy (TEM) has been used for many years to study the pineal gland it is timely to evaluate what progress has been achieved by using this technique and to speculate which aspects of pineal research may benefit most by its application in the future.
Forensic tools for the diagnosis of electrocution death: Case study and literature review
2018
Diagnosis of death by electrocution may be difficult when electric marking is not visible or unclear. Accordingly, the body of a man who appeared to have died from accidental electrocution was carefully forensically analysed. Macroscopic and microscopic analysis of the current mark was carried out using a variable-pressure scanning electron microscope equipped with energy dispersive X-ray microanalyser to highlight skin metallisation, indicating the presence of iron and zinc. The histological findings of electrocution myocardial damage were supported by the results of biochemical analysis which demonstrated the creatine kinase-MB and cardiac troponin I elevation. The effects of electric cu…
Insights on a Giant Aneurysm Treated Endovascularly
2015
Background Endovascular treatment with stent-assisted Guglielmi detachable coils is an accepted method for treating intracranial giant aneurysms that otherwise would require more invasive or destructive treatment or could not be treated at all. Nevertheless, there is a paucity of information concerning inner postcoiling aneurysmal changes in human subjects over the long term. We report a postmortem analysis of a patient with a giant aneurysm at the vertebrobasilar junction (VBJ) who was treated endovascularly and studied pathologically 24 months after treatment. Materials and Method The head was removed at autopsy and prefixed in a 10% neutral buffered formalin solution. The brain was gen…
