Agricultural potential of anaerobically digested industrial orange waste with and without aerobic posttreatment
2012
The potential of anaerobically digested orange waste with (AAD) and without (AD) aerobic post-treatment for use in agriculture was evaluated through chemical analyses, short-term phytotoxicity and long-term plant assays. Chemical analyses showed that AD contained ammonia and organic acids, and aerobic post-treatment did not significantly remove these phytotoxins. The N:P2O5:K2O ratio in AD was 1:0.26:0.96 and aerobic post-treatment did not change the composition in AAD except for K2O (1:0.26:1.24). Heavy metal contents in AD and AAD were more or less the same and were below the upper limit recommended for non-sewage sludge application on agricultural soils. Short-term phytotoxicity tests sh…
Krāsu redzes testa aprobācija datorizētajam redzes skrīningam
2022
Mērķis: veikt datorizēta krāsu redzes testa aprobāciju un novērtēt tā piemērotību krāsu redzes defektu atklāšanā. Pētījumā pirmajā daļā, krāsu redze tika pārbaudīta 74 dalībniekiem vecumā no 20 līdz 50 gadiem, izmantojot datorizēto krāsu redzes skrīninga testu un Richmond HRR testu dienas gaismas apstākļos. Rezultātu atšķirība bija statistiski nozīmīga (p < 0,05). Otrajā pētījuma daļā krāsu redze tika pārbaudīta 26 cilvēkiem vecumā no 20 līdz 24 gadiem, izmantojot anomaloskopu un datorizēto testu tumsas apstākļos. Jaunizveidotais tests uzrādīja augstu precizitāti rezultātos ar anomaloskopu. Tika secināts, ka telpas apgaismojums ietekmē datora testa efektivitāti krāsu redzes defekta noteikša…
La falta de reproducibilitat de la investigació: L'estadística com a legitimació del resultat
2014
La investigació científica es legitima mitjançant la replicació dels seus resultats, però els esforços per replicar afirmacions enganyoses exhaureixen el finançament. Ens centrarem en una d’aquestes errades: els resultats de proves estadístiques que ofereixen falsos positius a causa de l’atzar. Els mètodes estadístics clàssics confien en un p-valor per a ponderar les proves enfront d’una hipòtesi nul·la, però les proves d’hipòtesis bayesianes ofereixen resultats més fàcils de comprendre, sempre que hom puga especificar distribucions a priori per a la hipòtesi alternativa. Descriurem noves proves, les UMPBT, tests bayesians que ofereixen una especificació per defecte de les alternatives a pr…
Thiazole Analogues of the Marine Alkaloid Nortopsentin as Inhibitors of Bacterial Biofilm Formation
2020
Anti-virulence strategy is currently considered a promising approach to overcome the global threat of the antibiotic resistance. Among different bacterial virulence factors, the biofilm formation is recognized as one of the most relevant. Considering the high and growing percentage of multi-drug resistant infections that are biofilm-mediated, new therapeutic agents capable of counteracting the formation of biofilms are urgently required. In this scenario, a new series of 18 thiazole derivatives was efficiently synthesized and evaluated for its ability to inhibit biofilm formation against the Gram-positive bacterial reference strains Staphylococcus aureus ATCC 25923 and S. aureus ATCC 6538 a…

À la recherche de l’intelligence : de la mesure et de l’organisation
2016
Cet ouvrage aborde le champ des difficultés et des troubles de la vie intellectuelle et cognitive dans l’enfance et, plus généralement, celui des apprentissages et des moyens psychiques d’accès à la connaissance impliqués dans la réussite scolaire en particulier, et dans la réussite plus globale de l’enfant dans sa vie d’enfant, son bien-être, son développement harmonieux et dans sa future vie d’adulte.Fondé sur l’expérience clinique des auteurs auprès des enfants et des adolescents, mais aussi sur un enseignement dans le cadre d’un Diplôme universitaire, ce livre apporte également un éclairage plus large sur les processus impliqués dans les activités d’apprendre, de connaître et de penser,…
Resolving tensions caused by high-stakes assessment in an L2 classroom through mediation
2022
The Finnish classroom assessment culture is considered that of assessment for learning. The situation in upper-secondary schools is different, however. While teachers in Finland appreciate assessment supporting learning, they feel unable to merge it with assessment of learning outcomes, and favour the latter due to the Matriculation Examination (ME; e.g. Leontjev, submitted), a high-stakes exam growingly used in university admission. Learners, likewise, expect teachers to prepare them for the ME (Lakkala & Ilomäki, 2013), the results of which play a significant role in their further studies. The tension between assessment for learning and exam preparation is, therefore, often resolved i…
Test R-W jako trafne narzędzie w badaniach przesiewowych z zakresu psychologii pracy
2018
The R-W test is a tool examining the speed and accuracy of thinking used in labor psychology. It is described as a tool „filled with the intellectual component”, however, there is no validation data in the literature confirming that the R-W test exam some aspect of intellectual abilities. To fill this gap, validation studies were conducted. In the fi rst one, conducted on a group of drivers (N=105), the R-W test relationship with the complex reaction time, attention, as well as the participants level of education were revealed. In study 2 conducted on a group of students (N=150) the relationship between the R-W test and fl uid intelligence, perceptivity and attention, as well as anxiety as …
Double copies of blaKPC-3::Tn4401a on an IncX3 plasmid in Klebsiella pneumoniae successful clone ST512 from Italy
2015
ABSTRACT A carbapenem-resistant sequence type 512 (ST512) Klebsiella pneumoniae carbapenemase 3 (KPC-3)-producing K. pneumoniae strain showing a novel variant plasmid content was isolated in Palermo, Italy, in 2014. ST512 is a worldwide successful clone associated with the spread of bla KPC genes located on the IncFIIk pKpQIL plasmid. In our ST512 strain, the bla KPC-3 gene was unusually located on an IncX3 plasmid, whose complete sequence was determined. Two copies of bla KPC-3 ::Tn 4401a caused by intramolecular transposition events were detected in the plasmid.
Evaluación y caracterización biomecánica de los trinquetes de pelota valenciana. (Biomechanical assessment and characterization of the Valencian ball…
2012
El trinquete es la instalacion de referencia en la practica de la pelota valenciana, donde se juegan las modalidades profesionales de escala i corda y raspall. Sin embargo, no existe una normativa ni procedimientos de ensayo especificos que permitan definir las caracteristicas mecanicas que deben reunir paredes y pavimento del trinquete, para que los jugadores tengan una practica segura y optimicen su rendimiento. El objetivo de este estudio fue analizar diferentes variables mecanicas en las instalaciones de juego, determinar los procedimientos de ensayo mas adecuados y, finalmente, proponer unos valores mecanicos que definan una instalacion de calidad. Los estudios se llevaron a cabo en 10…
