Ils investissent une part croissante de leur épargne à l’étranger, via les intermédiaires financiers.Ménages, patrimoine financier, épargne, intermédiation, dépôts, crédits, titres de créance, valeurs mobilières, actions, OPCVM, sociétés d’assurance, profondeur financière, bases de détention de titres.
Productivity, heritability and stability analysis of a Moroccan sugar beet germplasm
Received: January 19th, 2021 ; Accepted: March 27th, 2021 ; Published: April 6th 2021 ; Correspondence: [email protected] testing is the second part of maternal recurrent selection scheme adopted by
INRA-Morocco for the national sugar beet breeding programme. The objective of this study is
sugar beet germplasm productivity, heritability and stability analysis. The studied material
concern 18 half-sib families (HSF) preselected initially for their seed production potential. Trials
were conducted using randomised complete blocks designs during, 2013/14, 2014/15, 2015/16,
2017/18 campaigns in two experimental fields of INRA-Morocco; Sidi Allal Tazi (34° 30' N, 6°
19' W) and Larache (35° 11’ N, 6° 09’ W). Evaluated parameters concern the vigour, root weight
(RW), leaf biomass yield (LBY), and sugar content (Sc). Data analysis by comparative
procedures explores different accordance degrees of HSF versus controls. Good vegetative
growth was observed, 85.6% closer to the maximal indicated scale level. The RW was
significantly influenced by the genotype and reached a maximum of 1.06 kg versus 1.08 kg
average recorded by controls. Sugar content recorded mean was 20.97% in HSF versus 21.39%
in the controls. Most of HSF revealed mean values close to Z-type variety. Estimated heritability
was 0.5 for RW, 0.2 for the LBY, and 0.02 for Sc. Sugar content was influenced by the
environment and explained by the AMMI model (73.6%) versus 53.9% and 44.4% for root weight
and leaf biomass yield respectively. The AMMI stability values showed F11, F12, F16, and F17
families as the most performing and stable HSF. Results demonstrate the relevance of the
maternal recurrent selection scheme of the on-going national breeding programme

Les comportements patrimoniaux des ménages en France : évolutions et déterminants entre 2004 et 2010.
À la lumière des informations issues des enquêtes Patrimoine 2004 et 2010 de l’INSEE et des évaluations des comptes nationaux financiers établis par la Banque de France, l’article propose une première analyse des ajustements patrimoniaux des ménages français depuis 2007.épargne, ménages, portefeuilles, immobilier, risques.
Variation intraspécifique du potentiel invasif de la morelle jaune (Solanum elaeagnifolium Cav.) au Maroc : Influence des conditions écologiques.
Le potentiel invasif (PI) de Solanum elaeagnifolium Cav. (SOLEL) au Maroc et les conditions écologiques qui le favoriseraient ne sont pas connus. L’objectif de cette étude a été donc d’évaluer la variabilité du PI et sa structuration et identifier les conditions écologiques favorisant la classe de PI la plus invasive. Pour ce faire, le PI de 188 populations représentatives de différentes conditions écologiques présentes au Maroc a été déterminé par l’analyse de traits d’histoire de vie de SOLEL liés à la reproduction sexuée. L’analyse de la variabilité du Pi et de sa structuration par Classification Ascendant Hiérarchique (CAH) et Analyse Discriminante Linéaire (ADL) a permis d’établir des classes de PI. L’influence des conditions écologiques sur la distribution de ces classes de PI a été évaluée. L’analyse des 11 variables choisies a montré une grande variabilité phénotypique de SOLEL. L’analyse par regroupement a mis en évidence quatre groupes distincts de PI. Pour chacune des six variables liées au PI, la comparaison des moyennes de ces groupes a défini quatre classes de PI, la classe la plus invasive ayant le plus grand nombre de moyennes les plus élevées. L’étude de l’influence des conditions écologiques sur la distribution des classes de PI a montré que les conditions climatiques et d’altitude les plus sévères favoriseraient la classe la plus invasive.
Turbulent thermal diffusion in a multi-fan turbulence generator with the imposed mean temperature gradient
We studied experimentally the effect of turbulent thermal diffusion in a
multi-fan turbulence generator which produces a nearly homogeneous and
isotropic flow with a small mean velocity. Using Particle Image Velocimetry and
Image Processing techniques we showed that in a turbulent flow with an imposed
mean vertical temperature gradient (stably stratified flow) particles
accumulate in the regions with the mean temperature minimum. These experiments
detected the effect of turbulent thermal diffusion in a multi-fan turbulence
generator for relatively high Reynolds numbers. The experimental results are in
compliance with the results of the previous experimental studies of turbulent
thermal diffusion in oscillating grids turbulence (Buchholz et al. 2004;
Eidelman et al. 2004). We demonstrated that turbulent thermal diffusion is an
universal phenomenon. It occurs independently of the method of turbulence
generation, and the qualitative behavior of particle spatial distribution in
these very different turbulent flows is similar. Competition between turbulent
fluxes caused by turbulent thermal diffusion and turbulent diffusion determines
the formation of particle inhomogeneities.Comment: 9 pages, 9 figure, REVTEX4, Experiments in Fluids, in pres
Разработка автоматизированного ИТП жилого здания
Объектом разработки системы является жилой дом с инженерными сетями в микрорайоне «Северный» в Заречном поселении Томского района Томской области.
Целью работы является разработка системы мониторинга и управления теплопотреблением здания, которая позволит вести точный учет потребляемой тепловой энергии, регулировать объем потребления в зависимости от текущих погодных условий, обеспечивать экономию энергоресурсов.
В результате разработана система, содержащая в себе компоненты, позволяющие производить учет и управление теплопотреблением здания. Причем все данные о работе системы, объемах потребления и параметрах теплоносителя поступают диспетчеру, имеющему возможность отслеживать все параметры системы удаленно.The object of the development of the system is a residential building with engineering services in the neighborhood "North" in Zarechny settlement Tomsk region Tomsk region.
The aim is to develop a building heat consumption monitoring and control system that will keep accurate records of heat energy consumption, adjusted consumption, depending on the current weather conditions, to ensure energy saving.
As a result, we developed a system, which contains the components to allow for registration and control of heat consumption of the building. Moreover, all data on the system performance, volume and consumption parameters receives coolant controller having the ability to track all system parameters remotely
Two novel connexin32 mutations cause early onset X-linked Charcot-Marie-Tooth disease
<p>Abstract</p> <p>Background</p> <p>X-linked Charcot-Marie Tooth (CMT) is caused by mutations in the connexin32 gene that encodes a polypeptide which is arranged in hexameric array and form gap junctions.</p> <p>Methods</p> <p>We describe two novel mutations in the connexin32 gene in two Norwegian families.</p> <p>Results</p> <p>Family 1 had a c.225delG (R75fsX83) which causes a frameshift and premature stop codon at position 247. This probably results in a shorter non-functional protein structure. Affected individuals had an early age at onset usually in the first decade. The symptoms were more severe in men than women. All had severe muscle weakness in the legs. Several abortions were observed in this family. Family 2 had a c.536 G>A (C179Y) transition which causes a change of the highly conserved cysteine residue, i.e. disruption of at least one of three disulfide bridges. The mean age at onset was in the first decade. Muscle wasting was severe and correlated with muscle weakness in legs. The men and one woman also had symptom from their hands.</p> <p>The neuropathy is demyelinating and the nerve conduction velocities were in the intermediate range (25–49 m/s). Affected individuals had symmetrical clinical findings, while the neurophysiology revealed minor asymmetrical findings in nerve conduction velocity in 6 of 10 affected individuals.</p> <p>Conclusion</p> <p>The two novel mutations in the connexin32 gene are more severe than the majority of previously described mutations possibly due to the severe structural change of the gap junction they encode.</p
