Behaviour of Extractives in Norway Spruce (Picea abies) Bark during Pile Storage
2022
The current practices regarding the procurement chain of forest industry sidestreams, such as conifer bark, do not always lead to optimal conditions for preserving individual chemical compounds. This study investigates the standard way of storing bark in large piles in an open area. We mainly focus on the degradation of the most essential hydrophilic and hydrophobic extractives and carbohydrates. First, two large 450 m3 piles of bark from Norway spruce (Picea abies) were formed, one of which was covered with snow. The degradation of the bark extractives was monitored for 24 weeks. Samples were taken from the middle, side and top of the pile. Each sample was extracted at 120 °C with both n-h…

¿Por qué los estudiantes de la Universidad Pedagógica ISFODOSU escogen la carrera de Educación?
2020
As part of research aimed at establishing the profiles of students of new entry at ISFODOSU, we include vocational variables to determine the most important motivations for the choice of career of the participants, as well as for the election of this university and opinion on its technological resources. The sample (No. 744) was chosen at random, proportionally among the Enclosures, Careers and Sex strata. First, we validate the FIT-Choice scale with two confirmatory factorial analyses. The 12 motivational factors showed a good level of fit (RMSEA .062; CFI .92 and TLI .901, as well as the 6 perceptual factors (RMSEA .062; CFI .944 and TLI .924). The reliability of the motivational factors …
Tensions and challenges concerning ethics on video research with young children : experiences from an international collaboration among seven countri…
2018
This article and the four videos linked to this article are a result of the earliest experiences in establishing an international research collaboration among seven countries in the Project Social and emotional experiences in transition through the early years. We draw attention to the complex issues surrounding the many processes, beliefs and attitudes about infants in research that permeated our processes of gaining ethical approval for the international study and which posed many challenges for our project. Through a process of reflective analysis, we have identified a range of ethical tensions and issues which the different countries involved in this international study faced in gaining…
L’ADATTAMENTO DEI PRESTITI SICILIANI NELLE VARIETÀ SICULOALBANESI: UN CONTRIBUTO ALLE QUESTIONI FONETICHE DEL SICILIANO
2018
Come è noto, le varietà italoalbanesi sono caratterizzate da una notevole presenza di prestiti romanzi, frutto del plurisecolare contatto con le varietà dei territori che li hanno ospitati. È altrettanto noto che i prestiti lessicali di una lingua minoritaria presentano in genere lo stadio conservativo e, per l’aspetto fonetico, le condizioni del periodo nel quale si sono acclimatati. Disponendo, allora, di un termine post quem sul piano storico (in ragione del fatto che la presenza degli Albanesi in Sicilia risale al XV secolo) e di un precisa collocazione areale delle comunità albanofone, un’analisi attenta ai processi di adattamento fonetico-fonologico dei prestiti siciliani delle variet…
The Effect of Predator Population Dynamics on Batesian Mimicry Complexes.
2022
Understanding Batesian mimicry is a classic problem in evolutionary biology. In Batesian mimicry, a defended species (the model) is mimicked by an undefended species (the mimic). Prior theories have emphasized the role of predator behavior and learning as well as evolution in model-mimic complexes but have not examined the role of population dynamics in potentially governing the relative abundances and even persistence of model-mimic systems. Here, we examined the effect of the population dynamics of predators and alternative prey on the prevalence of warning-signaling prey composed of models and mimics. Using optimal foraging theory and signal detection theory, we found that the inclusion …

Comerç, indústria i oci al Montaverner dels primers seixanta a través de la publicitat
1997
Dins del context de la nova història d'ampliació d'espais i de noves fonts, volem ubicar aquest estudi que, en el marc de la historiografia de caràcter local i de re-construcció de la vida quotidiana, intenta rememorar la realitat socioeconómica de la població i els punts d'ubicació del comerç, la indústria i l'oci del Montaverner en els primers anys de la década deis 60, utilitzant com a font la publicitat inserida en el llibre de festes del poble publicat en 1963.

Vaginal infection of mice with HSV type 2 variant ER−: A new animal model for human primary genital HSV type 2 infections
1992
Abstract Studying the pathogenesis of vaginal infections in mice with two variants of Herpes simplex virus type 2 (HSV-2) strain ER we observed that both variants ER+ and ER− caused severe vaginitis but only ER+ invaded the CNS leading to lethal neurological disease. In contrast, mice infected with ER− cleared the virus from the vagina and recovered from infection. ER+ and ER− expressed equal levels of thymidine kinase (TK) indicating a TK-independent difference in neurovirulence. Using the non-neurovirulent variant ER−, we were able to investigate humoral immune responses late after infection. Vaginal infection with ER− suppressed serum antibody formation after a secondary systemic HSV-1 i…
