Association between toenail scandium levels and risk of acute myocardial infarction in European men: the EURAMIC and Heavy Metals Study
2002
The association between scandium status and risk of acute myocardial infarction (MI) was examined in a multicentre case control study in 10 centres from Europe and Israel. Scandium in toenails was assessed in 684 cases and 724 controls less than 70 years of age. Mean concentrations of toenail scandium were 6.74 micro/kg in cases and 7.75 microg/kg in controls. Scandium among controls, adjusted for age and centre was positively associated with concentrations of lycopene and oleic acid in adipose tissue (P = 0.002 for both nutrients). Pearson correlations adjusted for age and centre were significant (P0.05) between scandium and lycopene (r = 0.08), zinc (r = 0.08), mercury (r = 0.18) and olei…
A Lotka-type model for oscillations in surface reactions
1997
In this paper we introduce a reaction model on a lattice which leads to oscillations. The model consists of two monomolecular and one bimolecular reaction step and is related to the Lotka model. Despite the simple evolution rules, the model shows a complex behaviour (i.e. the appearance of oscillations). This offers us the opportunity to test different types of stochastic approximations and compare them with the results of a Monte Carlo simulation. The simulation is performed on a large lattice (L = 1024) in order to take long-range correlations into account. Comparing the results of this simulation with the stochastic approaches shows that only advanced numerical approximations are able to…
Inpatient Step Counts, Symptom Severity, and Perceived Health Status After Lung Resection Surgery.
2020
BACKGROUND The clinical relevance of inpatient step counts after lung surgery remains unknown. OBJECTIVE The aim of this study was to identify those factors related to physical activity measured by step count, during the inpatient stay, and its relationship with symptom severity and perceived health status at hospital admission, discharge, and 1 month after discharge. METHODS We studied the inpatient step count of 73 participants who underwent lung resection surgery. The number of steps was measured using a triaxial accelerometer. The health status and the severity of symptoms were examined at hospital admission, discharge, and 1 month after discharge. RESULTS Of the 73 participants, 35 wer…
Economic Factors of Labor Migration Analysis

Population of Latvia is declining every year due to rate of natural decrease and negative rate of net migration indicators [1]. It is a topical issue since it affects stability and growth of the country.
Linking the residential satisfaction to landscape metrics: a tool for urban planning?
2010
International audience; This paper examines the links between residential satisfaction of periurban households and landscape structure of their spatial neighbourhood. Satisfaction of people was measured using a survey while landscape composition was quantified from remotely sensed data. Results are simulated in order to identify areas of satisfaction.
Muscular strength profiles and anthropometry in random samples of men aged 31–35, 51–55 and 71–75 years
1985
Maximal isometric muscular strength and anthropometric characteristics were studied among three random samples each containing about 180 Finnish men belonging to three generation cohorts, and having a mean age of 32·9 ± 1·4, 53·1 ± 1·5 and 72·7± 1·4 years. Strength was measured on special dynamometers for grip, trunk and knee extension and trunk and elbow flexion. The anthropometric characteristics included body height, weight, body-mass index, skeletal weight, fat weight and a weight factor. The youngest cohort had the highest and the oldest cohort the lowest values for strength as well as body height and fat-free body weight, while the middle-aged group had the highest and the youngest gr…
Isoerosivity and erosion risk map for Sicily
1991
This paper reviews simplified methods for evaluating the rainfall erosivity index and proposes two relationships for estimating the annual value of Wischmeier's rainfall erosivity index at sites equipped with recording and non-recording raingauges. For the Sicilian region, the FAO index was also found to represent the erosion risk. A regional relationship to estimate the standard deviation of the annual erosivity index is proposed. The isoerosivity map is plotted by using 41 values of the rainfall erosivity index calculated by Wischmeier's procedure and 128 values estimated according to a relationship proposed by the authors. Finally, for each of 169 sites, an erosion risk index is calculat…
The role of shame and guilt in social anxiety disorder
2021
Abstract Research suggests that shame and guilt may play a role in anxiety disorders. For social anxiety disorder (SAD), however, only a few studies investigated patients with the primary diagnosis of SAD. Thus, further research on shame and guilt in SAD is required. A secondary analysis of Data from the SOPHO-NET multicenter treatment study was performed. In a large sample of N = 495 patients with the primary diagnosis of SAD the relationship between shame and guilt with symptoms of social anxiety, depression, and interpersonal problems was examined by means of correlation analysis and additionally, a hierarchical linear regression analysis. To assess SAD, the German version of the Structu…
Correlation Analysis between External Factors and Students’ Physics Learning Achievement
2018
Research was conducted to determine whether there is 1) the relationship between the state of the family of learning achievement, 2) the relationship between the state schools of learning achievement, 3) the relationship between communities of learning achievement, and 4) the relationship between the state of the family, school and community environment against learning achievement. This research is associative quantitative correlational analysis techniques. The results showed: 1) There is a positive relationship between the state of the family of learning achievement, the result of the calculation shows r table> count r ie 0.51 > 0.38, 2) There is a positive relationship between the …
Estudio piloto de la validez convergente de la adaptación española del Denison Organizational Culture Survey
2016
espanolEl (DOCS, Cuestionario de Cultura Organizacional de Denison) es uno de los instrumentos mas utilizados en el analisis de la cultura organizacional. El objetivo de este articulo es analizar la validez convergente de la version en espanol del DOCS. Para ello hemos empleado otro instrumento de gran relevancia y utilizacion en el campo de la psicologia de las organizaciones, el Organizational Culture Inventory (OCI, Inventario de Cultura Organizacional) de Cooke y Lafferty. Hemos evaluado la validez convergente de estos cuestionarios por medio de correlaciones de Pearson, utilizando una muestra de 344 miembros de una universidad espanola pertenecientes a diferentes equipos de investigaci…
