Coherent combining in an Yb doped double core fiber laser

International audienceCoherent combining is demonstrated in a clad pumped Yb doped double core fiber laser. A slope efficiency of more than 70 % is achieved with 96 % of the total output power on the fundamental mode of one of the two cores. This high combining efficiency is obtained when both cores are coupled via a biconical fused taper in a Michelson interferometer configuration

Priority areas identification and management strategies for landscape forest restoration in Mozambique

In the last decades, Forest Landscape Restoration (FLR) emerged as a solution to restore ecological integrity while enhancing human well-being in deforested or degraded forest landscape. One key challenge in implementing FLR includes the identification of suitable intervention areas according to the restoration strategy (active or passive restoration) and the local socio-bioophysical constraints. The aim of this study was to develop a new approach to locate where forest landscape restoration would enhance multiple ecosystem functions and identified management strategies (passive or active restoration) in two districts in central Mozambique. The methodology involved (i) the ecosystem functions mapping to identify multifunctional hotspot and (ii) the assessment of the land-use history to differentiate areas with low or high regeneration potential. We derived three spatially-explicit ecosystem functions (biomass, soil carbon sequestration potential and forest connectivity) and one characteristic (woody species diversity potential) based on field inventory. We mapped and analyzed land-use history, defined by the current fallow age, the time since the first forest clearcutting and the number of crop-fallow cycles. The results showed that 118,629 ha were identified as priority areas (10.9% of the study area) for forest landscape restoration, with 42,255 ha (36%) with natural regeneration potential and 76,373 ha (64%) with low regeneration potential and would require human activities to recover ecosystem functionality and ability to provide ecosystem services. This study provides new insights for integrating ecosystem functions at landscape scale to support decision making for forest restoration and support the Mozambican government commitments to restore degraded landscapes at national scale

Development and viability of biofilms grown on experimental abutments mimicking dental implants : an in vivo model

To determine whether an experimental abutment mimicking the macro- and microstructure of a dental implant is a suitable method for recovering biofilm, and to describe the features of biofilms formed around such abutments on healthy implants. Experimental abutments were used in 15 patients without peri-implant diseases. After 14 days? absence of dental hygiene in this area, the abutments were retrieved and analyzed through confocal laser scanning microscopy and scanning electron microscopy. The biofilm formation on the surface of the first 5 abutments was determined by a fluorescence-staining method using SYTO9 nucleic acid stain. In order to study the biofilm?s coverage and vitality, 10 additional abutments were assessed using live and dead bacterial viability. Descriptive and bivariate analyses of the data were performed. A global plaque coverage of the abutments was observed in all cases. The submucosal area of the abutment was mostly covered with biofilm (over 21%). Moreover, significant differences between supra- and subgingival locations were detected. This in vivo experimental model allows detailed observation of the extensive plaque growth found on exposed experimental abutments mimicking dental implants when hygiene measures are absent. The biofilm coverage is significantly higher in the supragingival zone than in the subgingival portion

The emotional vocabulary of young people

Universidad de Lérida, España [email protected] -- AGNÈS ROS MORENTE. Universidad de Lérida, España [email protected] entendemos la salud desde una perspectiva global, es decir, no sólo física sino también mental, el bienestar emocional es clave para poder tener un completo estado de salud. La adolescencia es una etapa en la que se producen muchos cambios y las emociones juegan un papel fundamental. Así pues, la educación emocional adquiere gran importancia en este periodo. Para entender las emociones, el primer paso es tener conciencia emocional y, en este sentido, es básico tener un buen vocabulario emocional, ya que poner nombre a las emociones nos hace tener conciencia de ellas. Por este motivo, el siguiente estudio consiste en examinar y hacer un análisis sobre el vocabulario emocional en adolescentes. Para ello se ha contado con una muestra de 431 adolescentes de entre 14 y 18 años, en concreto, 173 alumnos de segundo ciclo de ESO y 258 alumnos de bachillerato. Se ha analizado el vocabulario del alumnado mediante una prueba estandarizada que consiste en escribir en tres minutos el número máximo de emociones posibles. Una vez obtenidos los datos se ha realizado un análisis estadístico, observando así las diferencias significativas entre las diferentes variables del alumnado. Como principales resultados se ha obtenido que el número de emociones tanto de ESO como de bachillerato no es muy elevado. Además, hay más cantidad de palabras en las familias emocionales de emociones negativas y la familia en la que más palabras se han escrito es la de tristeza con gran diferencia con respecto a las otras, tanto en ESO como en bachillerato.Understanding health from a global perspective –not only physical but also mental–, emotional well-being is key to achieve a complete state of health. Adolescence is a stage where many changes take place and in which emotions play a fundamental role. Therefore, emotional education acquires great importance in this period. To understand emotions, the first step is to have emotional awareness. In this sense, it becomes essential to have a vast emotional vocabulary because naming emotions makes us aware of them. Hence, this study consists of an analysis of this emotional vocabulary. The sample consists of 431 adolescents, high school students (14 to 18 years old). We analyzed the students' vocabulary using a standardized test that consists of writing in three minutes the maximum number of words that describe emotions. Once we drew the data, we carried out a statistical analysis through the SPSS.20 package, thus observing the significant differences between the different variables of the students. The main results show the number of written emotions is not very high. In addition, there are more words in the negative emotional families, and the sad family is the one with the most words written
