Quantitative Estimation of Major and Trace Elements in Coals of the Benue Trough, Nigeria
2013
The concentrations of major and trace elements in ash residues of coals of the Benue Trough, Nigeria have been determined by electron microprobe and laser ablation-inductively coupled plasma-mass spectrometry, respectively. Major and trace element determination in rocks by fusion on an iridium strip heater followed by electron microprobe and laser ablation-inductively coupled plasma-mass spectrometry is extended here to coal ash, and the accuracy of the method is evaluated by including an Argonne Premium Coal reference sample in each analysis program. Si and Al are the major elements detected in the coal ashes. An assessment using worldwide concentration ranges of trace elements in coal ash…
The Willingness to Intervene in Cases of Intimate Partner Violence Against Women (WI-IPVAW) Scale: Development and Validation of the Long and Short V…
2018
Willingness to intervene when one becomes aware of a case of intimate partner violence against women (IPVAW) reflects the level of tolerance and acceptance of this type of violence in society. Increasing the likelihood of intervention to help victims of IPVAW is also a target for prevention strategies aiming to increase informal social control of IPVAW. In this study, we present the development and validation of the Willingness to Intervene in Cases of Intimate Partner Violence (WI-IPVAW) scale. We report data for both the long and short versions of the scale. We analyzed the latent structure, the reliability and validity of the WI-IPVAW across four samples (N = 1648). Factor analyses suppo…
On the Influence of the Evaluation Methods in Conjoint Design — Some Empirical Results
2000
It is the goal of conjoint analysis to explain and predict preferences of customers (Schweikl 1985). Variants of predefined manifestations of attributes of various product concepts (both real and hypothetical) are created, and these are presented to test persons for evaluation. The contributions (partial benefits) the various attributes make to overall preference (overall benefit) are estimated on the basis of overall preference judgments (Green and Srinivasan 1978).
HIV-Infected Children and Nutrition: The Friend and The Foe
2019
The impact of nutrition on HIV-infected children has been evaluated in multiple studies. Our review of the current trends of nutrition-related studies revealed that the focus has moved from simply the disease consequences of HIV to ensuring that antiretroviral therapy-treated children are well nourished to ensure growth and development. This update aims to present the state of the art regarding nutrition of HIV-infected children and the real potential for nutrition to serve as a dynamic therapy in this group. Recent World Health Organization reports indicate that the HIV/AIDS disease is curbing in incidence worldwide despite the high 1.8 million children, less than 15 years, reported in 201…
E-book Readers in Higher Education: Student Reading Preferences and Other Data from Surveys at the University of Agder
2013
Published version of an article from the journal Sage Open: http://sgo.sagepub.com/. Also available from the publisher: http://dx.doi.org/10.1177/2158244013486493 Open Access This paper reports on a research project at the University of Agder that has studied the use of e-readers as a tool for academic study. E-readers (Kindle DX and iPad) were loaded with texts from required reading lists in five courses with 94 participating students. Initially 87 students responded to the invitation to participate in a survey, but eventually 13 of these submissions had to be removed, as the degree of completion was not sufficient. The final response rate achieved was 79%. Students were in general positiv…
A pilot study on self-perceived need for management training among medical students in Latvia
2013
Objectives: To assess the self-perceived need and preferred format for educational intervention among Latvian medical students in fostering the increasing demanding of management-related competences for healthcare professionals. Methods: A cross sectional study design was used to assess student-perceived deficiencies and the need for knowledge and skills in 10 different domains of activity. All medical students from one of the two major Latvian universities were invited to participate in this survey. The knowledge gap between perceived deficiency and actual need for training in specific domains was calculated. Possible correlations between a total gap of knowledge and selected demographic p…

Rational supershapes for surface reconstruction
2007
Simple representation of complex 3D data sets is a fundamental problem in computer vision. From a quality control perspective, it is crucial to use efficient and simple techniques do define a reference model for further recognition or comparison tasks. In this paper, we focus on reverse engineering 3D data sets by recovering rational supershapes to build an implicit function to represent mechanical parts. We derive existing techniques for superquadrics recovery to the supershapes and we adapt the concepts introduced for the ratioquadrics to introduce the rational supershapes. The main advantage of rational supershapes over standard supershapes is that the radius is now expressed as a ration…
Determination of total ribonucleotide pool in plant materials by high-pH anion-exchange high-performance liquid chromatography following extraction w…
2005
A new, improved method that only requires a potassium hydroxide extraction procedure is presented for the analysis of a full nucleotide pool in plant materials. Quantification was performed by high-pH anion-exchange chromatography (HPAEC) with UV detection after a potassium hydroxide extraction, and allowed the quantification of 13 linear ribonucleotides in a single run. The method has been validated by comparison of six extraction methods and also by measurement of the intracellular nucleotide levels of three plant species (cell cultures and leaves). The evolution of the nucleotide pool of Nicotiana tabacum cell culture during growth has also been measured, and showed an increase in the po…
Vulnerability, freedom of choice and structural global injustice: The “consent” to exploitation of migrant women workers
2019
This chapter analyzes the philosophical implications related to the “position of vulnerability” defined by the Directive 2011/36/EU on Preventing and Combating Trafficking in Human Beings and Protecting its Victims as “a situation in which the person concerned has no real or acceptable alternative but to submit to the abuse involved” (art. 2.2). In particular, the chapter focuses on the “choice” made by migrant women employed in care and domestic work and in the agricultural sector in Italy. The Italian labor market is marked by the exploitation of migrant women, especially women from Romania, due to social, economic and legal factors that will be considered from a gender perspective. Women…
