Seed isozyme variation in Petrocoptis A. Braun (Caryophyllaceae).
2001
Abstract The electrophoretic patterns of seven isozyme systems (ADH, AMY, AAT, GDH, LAP, MDH, and SOD) obtained from dormant seeds from 44 accessions belonging to 12 Petrocoptis taxa were compared in order to clarify taxonomic relationships within the genus. Overall, electrophoretic zymograms showed the presence of up 28 electromorphs, of which 26 were polymorphic among accessions. Mantel tests revealed a moderate level of correlation between the geographic distance matrix and several dissimilarity matrices based on the isozyme data ( r =0.3052–0.3376). The electrophoretic profiles of seed isozymes did not match closely the analytical taxonomic framework drawn from morphology. Many electrom…
Application of artificial neural networks and logistic regression to the prediction of forest fire danger in Galicia using MODIS data
2012
Fire danger models are a very useful tool for the prevention and extinction of forest fires. Some inputs of these models, such as vegetation status and temperature, can be obtained from remote sensing images, which offer higher spatial and temporal resolution than direct ground measures. In this paper, we focus on the Galicia region (north-west of Spain), and MODIS (Moderate Resolution Imaging Spectroradiometer) images are used to monitor vegetation status and to obtain land surface temperature as essential inputs in forest fire danger models. In this work, we tested the potential of artificial neural networks and logistic regression to estimate forest fire danger from remote sensing and f…
New geo-portal for MODIS/SEVIRI image products with geolocation-based retrieval functionality
2015
A large number of remote sensing data sets have been collected in recent years by Earth observation instruments such as the moderate resolution imaging spectroradiometer (MODIS) aboard the Terra/Aqua satellite and the spinning enhanced visible and infrared imager (SEVIRI) aboard the geostationary platform Meteosat Second Generation. The advanced remote sensing products resulting from the analysis of these data are useful in a wide variety of appli- cations but require significant resources in terms of storage, retrieval, and analysis. Despite the wide availability of these MODIS/SEVIRI products, the data coming from these instruments are spread among different locations and retrieved from d…
Drug Use Control Perception and Strategies in General and Clinical Population in a Spanish City
2021
Background: This article evaluates the perception of drug use control and strategies in Valencia City (Spain) in a general and clinical population, in two independent studies. Material and Methods: 1071 people participated. In the Study 1 (n= 924) the entire sample came from general population (GP), and in the Study 2 (n=147), 68 were drug users being treated in an Addictive Behaviors Unit (ABU), and 79 people of the GP. The drug use control perception and strategies in both subgroups were compared. The participants filled in the Drug Use Strategies Scale and a Drug Use Survey. Results: A high level of perception of drug control in GP was obtained (72,7% in the Study 1 and 67,5% in the Stud…
Physical Activity, Sedentary Behavior, and Academic Performance in Finnish Children
2013
Purpose: This study aimed to determine the relationships between objectively measured and self-reported physical activity, sedentary behavior, and academic performance in Finnish children. Methods: Two hundred and seventy-seven children from five schools in the Jyväskylä school district in Finland (58% of the 475 eligible students, mean age = 12.2 yr, 56% girls) participated in the study in the spring of 2011. Self-reported physical activity and screen time were evaluated with questions used in the WHO Health Behavior in School-Aged Children study. Children’s physical activity and sedentary time were measured objectively by using an ActiGraph GT1M/GT3X accelerometer for seven consecutive da…
Work strain in midlife and 28-year work ability trajectories
2011
We investigated the 28-year development trajectories of work ability among initially middle-aged male and female municipal employees and the association of perceived mental and physical work strain in midlife by work ability trajectory groups.The baseline data of the Finnish longitudinal study of municipal employees (FLAME) were collected in 1981 (N=6257) with follow-ups in 1985, 1992, 1997, and 2009. Work ability was assessed in all the waves as present perceived work ability relative to lifetime best. Altogether, N=2690 had work ability data in 1981 and 2009, and at least for one wave in between these years, and were included in group-based semi-parametric mixture modeling trajectory anal…
Increased average longevity among the "Tour de France" cyclists.
2011
It is widely held among the general population and even among health professionals that moderate exercise is a healthy practice but long term high intensity exercise is not. The specific amount of physical activity necessary for good health remains unclear. To date, longevity studies of elite athletes have been relatively sparse and the results are somewhat conflicting. The Tour de France is among the most gruelling sport events in the world, during which highly trained professional cyclists undertake high intensity exercise for a full 3 weeks. Consequently we set out to determine the longevity of the participants in the Tour de France, compared with that of the general population. We studi…
Intercomparison of remote-sensing based evapotranspiration algorithms over amazonian forests
2019
Abstract Evapotranspiration (ET) is considered a key variable in the understanding of the Amazonian tropical forests and their response to climate change. Remote-Sensing (RS) based evapotranspiration models are presented as a feasible means in order to provide accurate spatially-distributed ET estimates over this region. In this work, the performance of four commonly used ET RS models was evaluated over Amazonia using Moderate Resolution Imaging Spectroradiometer (MODIS) data. RS models included i) Priestley-Taylor Jet Propulsion Laboratory (PT-JPL), ii) Penman-Monteith MODIS operative parametrization (PM-Mu), iii) Surface Energy Balance System (SEBS), and iv) Satellite Application Facility…
Psoriasis moderada-grave en pacientes pediátricos y jóvenes: experiencia en el registro BIOBADADERM
2022
Resumen {0>El debut de la psoriasis en la edad pediatrica, aunque generalmente leve, puede requerir tratamiento sistemico en las formas moderadas o graves de la enfermedad. Childhood-onset psoriasis generally follows an indolent course but patients with moderate or severe disease may require systemic treatment. El objetivo de este trabajo es analizar la frecuencia relativa, las caracteristicas de los pacientes, el tratamiento empleado y los eventos adversos (EA) observados a partir del registro BIOBADADERM en ninos y jovenes con psoriasis moderada-grave. The aim of this study was to determine the relative proportion of children and young people aged up to 21 years with moderate to severe ps…
Bacterias halófilas moderadas aisladas de las minas salinas de Atacocha - Ayacucho
2007
Las bacterias halófilas producen una gran variedad de metabolitos y enzimas con interesantes aplicaciones bíotecnológicas. Con la finalidad de aislar bacterias halófilas moderadas de las minas salinas de Atacocha - Ayacucho, se recolectaron muestras de sal y se preenriquecieron en medio agua de sales al 5% suplementado con extracto de levadura al 0.5% durante una semana y luego se sembraron en medio sólido. De 40 aislados se seleccionaron 10 por presentar características morfológicas y culturales muy diferenciadas. A los aislados seleccionados se les determinó el rango de tolerancia al NaCl, temperatura, pH y sus características bioquímicas y nutricionales. Se encontró que los aislados tole…
