Dyvalocca : un projet pour l'étude des nuages bas de saison sèche sur la façade atlantique de l'Afrique centrale et de leur impact bioclimatique sur …

2020

Low-level clouds are key components of the climate but are not well represented in weather and climate models. Recently it has been shown that an extensive low-level cloud cover develops during the June-September main dry season in western equatorial Africa, from the coastal plains of Gabon and Congo-Brazzaville to the inland plateaus downstream of the low-mountain crests. Such a cloudy main dry season is unique in the moist Tropics and is likely to explain the presence of the densest and evergreen forests of Central Africa as evapotranspiration is low and the quality of light is high. The ANR-DFG funded “DYVALOCCA” project will conduct from 2020 to 2022 a field campaign, raise existing in-…

Development of an immunochromatographic assay based on carbon nanoparticles for the determination of the phytoregulator forchlorfenuron

2013

Rapid analytical methods enabling the determination of diverse targets are essential in a number of research areas, from clinical diagnostics to feed and food quality and safety. Herein, the development of a quantitative immunochromatographic assay for the detection of the synthetic phytoregulator forchlorfenuron (CPPU) is described. The competitive lateral flow immunoassay (LFIA) was based on the immobilization onto a nitrocellulose membrane of an ovalbumin-CPPU conjugate (test line) and on the use of an immunodetection ligand consisting of carbon nanoparticles labeled with an anti-CPPU monoclonal antibody through interaction with a secondary antibody. The presence of CPPU in horticultural…

Few-body insights of multiquark exotic hadrons

2018

In this contribution we discuss the adequate treatment of the $4-$ and $5-$body dynamics within a constituent quark framework. We stress that the variational and Born-Oppenheimer approximations give energies rather close to the exact ones, while the diquark approximation might be rather misleading. Hall-Post inequalities provide very useful lower bounds that exclude possible stable states for some mass ratios and color wave functions.

Una más de la familia. Au pairs atrapadas entre el capital humano y la economía moral

2018

In contemporary societies we are witnessing an expansion of the messages of human capital. These messages have as their central dimension idea of the self-entrepreneur, which implies a deepening in the logic of activation, while blurring the wage relations. In this scenario, young people with university degrees are becoming a favourite target in the offensive of human capital. The penetration of these human capital messages can be seen in the discourses of young university students who have been forced to leave the country during the crisis. In the present text we approach the discourses of young women who came out as au pairs. The characteristics of this figure place it in a space halfway …

Measurement of parity-violating spin asymmetries in W± production at midrapidity in longitudinally polarized p+p collisions

2016

We present midrapidity measurements from the PHENIX experiment of large parity-violating singlespin asymmetries of high transverse momentum electrons and positrons from W =Z decays, produced in longitudinally polarized p þ p collisions at center of mass energies of ffiffi s p ¼ 500 and 510 GeV. These asymmetries allow direct access to the antiquark polarized parton distribution functions due to the parityviolating nature of the W-boson coupling to quarks and antiquarks. The results presented are based on data collected in 2011, 2012, and 2013 with an integrated luminosity of 240 pb−1, which exceeds previous PHENIX published results by a factor of more than 27. These high Q2 data probe the p…

Atmospheric circulation modulates the spatial variability of temperature in the Atlantic-Arctic region

2019

International audience; The Arctic region has experienced significant warming during the past two decades with major implications on the cryosphere. The causes of Arctic amplification are still an open question within the scientific community, attracting recent interest. The goal of this study is to quantify the contribution of atmospheric circulation on temperature variability in the Atlantic–Arctic region at decadal to intra‐annual timescales from 1951 to 2014. Daily 20th Century reanalyses geopotential height anomalies at 500 hPa were clustered into different weather regimes to assess their contribution to observed temperature variability. The results show that in winter, 25% of the warm…

Structural Equation Modeling in Research on Brand Capital in Higher Education

2016

This  research  is  done  in  order  to  examine  the  role  of  the  brand  capital  in higher education. For this purpose, we analyze the main contributions of the literature  related  to  the  study  of  the  brand capital and  its  application  in  the educational  sector,  identifying  which  variables  determine  the  brand  capital in  the  higher  education  sector.  Once  we  establish  the  susceptible  brand capital in the higher education sector, an empirical research is done by using a questionnaire developed in Spanish language with a Likert scale of grade 5 in  which  1  point  means  "strongly  disagree"  and  5  mean  "strongly  agree", being based on the measurement scales…

Conflitto e bilanciamento tra diritti fondamentali. Una mappa dei problemi

2007

In the current jurisprudential debate, the issue of conflicts of rights is a widely debated one. The present essay aims at clarifying the main aspects of this ongoing debate, along the following lines: firstly, an historical account of the problem of balancing conflicting rights will be given, with an eye both to the American recent experience and to the Italian one. Secondly, it will be discussed whether and under what circumstances rights can conflict. Thirdly, after having acknowledged that conflicts of rights are in fact unavoidable, it will be necessary to examine the main technique of solving those conflicts: namely, the “weighing and balancing” technique. The main suggestion that is …

Perceptions, motives, and psychological flexibility associated with weight management

2012

Introduction: Overweight people are often able to lose weight with the help of professionals, but majority (about 85 %) of the weight losers fail to maintain behavioral changes that would lead to favorable results in the long term [1‐3]. Studies suggest that obesity treatment failures may reflect motivational and contextual impediments to weight loss, rather than limitations of the behavior change strategies per se [4, 5]. A stronger emphasis on motivational factors within a behavioral weight maintenance program offers promise for improving long-term outcomes. The motivation-focused approach has been shown to be as effective as the successful standard skill-based method in weight maintenanc…
