This paper presents a new energy vehicle driving control system based on image processing technology. Through processing and analysis of road images, the new energy vehicle driving control system is able to recognise road elements, plan a route, and calculate its direction and speed parameters. In order to improve the system’s applicability in various environments, it first divides the road image into two categories: road surface and other objects. Then, it uses a manual iteration method to determine the optimal threshold and suggests an adaptive threshold improvement method. Second, the system carries out feature extraction of road elements, including sample types like ramps, straight roads, curves, intersections, and obstacles. Through secondary feature extraction and sample type characterization, the system achieves the recognition and classification of various road elements. Ultimately, the system executed image capture, preprocessing, and boundary extraction. It then achieved vehicle navigation by using path planning and road centerline fitting. The technology determined the corner parameter and offered precise navigational directions for vehicles during the vehicle direction and speed parameter test. The driving control system for new energy cars is highly applicable and practical, offering efficient technical assistance for the safe operation of these vehicles in intricate road conditions.

The DC current transformer, which forms the foundation of the high-voltage DC transmission system, must be designed rationally and have accurate field testing. This study examines the causes of the faults in the field test system for the DC current transformer and suggests a closed-loop test technique for the field that builds upon empirical modal decomposition (EMD) filtering. The technique uses an 18-bit high-precision A/D acquisition and the EMD algorithm to filter out harmonics, which greatly increases the measurement accuracy of the test system. It also realizes the synchronous acquisition of the standard source analog quantity and the measured digital quantity through the high-precision synchronization module, which solves the error caused by the delay. The test findings indicate that the enhanced system removes data with significant inaccuracies in the standard value 6250A test, bringing the measured value closer to the standard value. Furthermore, a step source system was built and its accuracy and feasibility were confirmed by experiments for the purpose of measuring the transient step response of DC current transformers. The enhanced test equipment performs exceptionally well in transient and steady state tests and is highly valuable for engineering applications.
Hériter au Canada : portrait des
tendances entre 2005 et 2019. L’augmentation de la réception d’héritages chez les
familles québécoises et les ménages les moins éduqués
Authors: Biron-Boileau Camille
Published: February 2025

Cadre de la recherche : La contribution
grandissante de l’héritage aux inégalités sociales dans plusieurs pays stimule
la recherche sur la manière dont se déroule cette transmission au sein des
familles. Pourtant, très peu d’études ont été menées sur le sujet en contexte
canadien.

Objectifs : Cette recherche étudie
dans quelle mesure les familles canadiennes bénéficient de l’héritage en
fonction de leur position sociale. Elle vise aussi à étudier les tendances
temporelles propres au phénomène, ainsi que les facteurs explicatifs des
changements observés.

Méthodologie : À l’aide
des données de l’Enquête sur la sécurité financière de 2005, 2012, 2016 et 2019,
des régressions sont menées pour étudier les chances de réception d’un héritage,
ainsi que leur valeur, en fonction des caractéristiques des ménages et de
l’année de l’enquête.

Résultats : Les familles
au statut socio-économique plus élevé ont plus de chances de recevoir un
héritage, généralement d’une plus grande valeur. Une montée de l’héritage a
aussi été observée au Canada. Les changements dans la structure d’âge expliquent
en partie cette hausse, mais l’augmentation plus marquée observée au Québec et
chez les ménages au statut socio-économique moins élevé indique une influence
d’autres facteurs.

Conclusions : L’héritage
contribue à reproduire les inégalités économiques en raison de sa distribution
inégale et occupe une place grandissante au Canada. Le vieillissement des
populations explique une part des tendances, mais l’influence de la hausse dans
l’accession à la propriété et dans le prix de maisons, ainsi que d’un changement
dans les comportements d’accumulation patrimoniale pour les enfants, pourraient
aussi être en cause.

Contribution : Cet
article contribue à documenter l’héritage, jusqu’alors très peu étudié au
Canada. La distribution inégale de l’héritage soulève des enjeux relatifs à
l’égalité des chances et au rôle de l’État pour en diminuer les effets.
Patrimoine immobilier locatif et mobilité sociale :
les économies domestiques de propriétaires de classes populaires et
immigrées
Authors: Vignal Cécile
Published: February 2025

Cadre de la recherche : Dans un contexte
français d’accès généralisé à la propriété immobilière depuis les années 1980,
la propriété locative est longtemps restée le parent pauvre de l’analyse
sociologique au profit de l’analyse de la propriété occupante.

Objectifs : Cet article vise à mesurer les modalités
d’accumulation d’un patrimoine locatif pour des familles de classes populaires
selon les générations et le genre et à en mesurer les effets sur les
trajectoires sociales.

Méthodologie :
L’article s’appuie sur l’exploitation statistique de l’enquête « Histoire de Vie
et Patrimoine » (2017-2018) de l’Institut National de la Statistiques et des
Etudes Economiques (Insee) et sur le matériau constitué par une enquête par
entretiens auprès de 30 propriétaires bailleurs de classes supérieures, moyennes
et populaires de l’agglomération de Lille. Cet article focalise l’analyse sur
dix enquêtés de classes populaires dont l’un connaît une forte ascension sociale
vers les classes moyennes : 5 femmes et 5 hommes, âgés de 43 à 75 ans, d’origine
immigrée principalement maghrébine.

Résultats : L’analyse montre l’importance du travail matériel
d’autoréhabilitation et de division des logements qui a permis de devenir
propriétaire puis bailleur. La rente locative apparaît comme un moyen de
stabiliser l’économie du groupe familial, comme une forme de « travail de
subsistance » (Collectif Rosa Bonheur, 2019). Être propriétaire bailleur est un
marqueur de réussite sociale pour les familles immigrées soutenant la mobilité
sociale des enfants. L’égalité des droits de propriété sert, après une
séparation ou un décès, l’autonomie des femmes qui sont parvenues à défendre la
part du patrimoine qui leur revenait.

Conclusions : L’article aide à comprendre la mobilisation du groupe de
parenté dans le contexte d’économies domestiques populaires et le rôle de
l’espace urbain désindustrialisé dans la constitution d’un patrimoine immobilier
et d’une rente locative.

Contribution :
L’article contribue à la sociologie de la propriété des classes populaires et
immigrées et au renouvellement des analyses sur la stratification sociale.
L’essence de l’engagement paternel chez des pères agriculteurs
résidant en région éloignée : une étude phénoménologique
Authors: Gingras-Lacroix Gabriel , Labra Oscar
Published: February 2025

Cadre de recherche : Les écrits
scientifiques montrent que les agriculteurs sont particulièrement à risque de
vivre des problèmes de santé mentale. Or, plusieurs agriculteurs mentionnent que
leur rôle de père est en lien direct avec leur état de santé. Aucune étude, à ce
jour, ne s’est intéressée au vécu de l’engagement paternel chez ce groupe de
population.

Objectif : Cet article vise à
décrire le vécu de l’engagement paternel des agriculteurs abitibiens, tel que
perçu par ces derniers.

Méthodologie : Une
recherche phénoménologique de type descriptif a été menée auprès de 14
agriculteurs. Les données ont été recueillies à l’aide d’entrevues semi-dirigées
et une analyse phénoménologique descriptive a permis d’interpréter les
résultats.

Résultats : Les propos des
agriculteurs montrent qu’être présents activement auprès de leurs enfants
constitue l’essence de la paternité, ce qui les amène à s’engager en tant que
pères afin de répondre aux besoins physiologiques et émotionnels de leurs
enfants, d’être un mentor pour eux et d’assurer leur éducation.

Conclusions : Cette étude montre les enjeux relatifs à la
conciliation travail/famille propre aux agriculteurs. Or, d’autres études
devront être réalisées afin de mieux comprendre les impacts de ces enjeux sur le
bien-être des agriculteurs et de leurs familles.

Contribution : En plus d’examiner une population dont les conditions de
vie sont peu documentées, cette recherche montre qu’il faudrait soutenir
davantage les familles agricoles, notamment par la mise en place de ressources
permettant aux agriculteurs de bénéficier d’un congé de paternité, de se libérer
plus facilement pour prendre du temps en famille et d’amener leurs enfants au
travail de manière sécuritaire.
« Monsieur graine, donneur, mais pas papa » : le travail
narratif des mères seules par don
Authors: Lenouvel Margot
Published: February 2025

Cadre de la recherche :
La question des origines personnelles évolue au fur et à
mesure que se diversifient les manières de faire famille. En France, les
parents ayant recours au don de gamètes sont désormais encouragés à
transmettre à l’enfant un récit sur les circonstances de sa venue au monde.
Ces narrations prennent une place particulière pour les mères seules : il
s’agit d’attribuer une place à un donneur dans l’histoire familiale, sans
que celle-ci compense l’absence d’un deuxième parent.

Objectifs :
L’objectif de cet article consiste à analyser comment les
récits sur les origines - ici sur les donneurs - se construisent par les
mères seules.

Méthodologie :
Dans le cadre d’un travail de thèse, dix-huit entretiens
biographiques ont été réalisés auprès de femmes seules devenues mères en
ayant recours à un don de sperme, à l’étranger ou en France. Ces entretiens
sont complétés par l’analyse d’un groupe en ligne, terrain d’enquête fécond
pour observer les intimités familiales.

Résultats :
Dévoiler son histoire donne lieu à une variété de pratiques
et de stratégies narratives, fondées sur la norme morale d’une double
responsabilité des mères seules. Investiguer les narrations donne à voir la
place attribuée au donneur. Il incarne une figure symbolique de l’histoire
familiale, qui ne fait aucunement concurrence à la parenté et la filiation.
Sa place est construite dans un entre-soi féminin au sein des réseaux de
mères seules, puis négociée avec l’entourage familial. Plus encore, ces
récits se matérialisent à travers la création de supports (livres, images,
films, etc.), témoignant de la volonté des mères seules d’affirmer leur
modèle familial.

Conclusion :
La mise en récit des origines s’insère dans un travail
narratif des mères seules à destination de leur enfant et de l’entourage,
qui participe à la mémoire familiale.

Contribution :
Cet article contribue à une meilleure compréhension de
l’expérience parentale des mères seules, et plus globalement de la place
accordée à un donneur dans l’histoire des familles issues du don.

Assim, organizar e digitalizar o acervo dessa coleção é uma iniciativa estratégica para fortalecer sua relevância científica e promover sua utilização em estudos voltados à conservação da biodiversidade e à educação ambiental. Neste sentido, o trabalho teve como objetivo organizar, atualizar e digitalizar as informações da Coleção de Abelhas do IFRN, campus Pau dos Ferros, com o propósito de criar um banco de dados consolidado e acessível. Para isso, foram utilizados computadores com acesso à internet para a reorganização dos dados em planilhas digitais online, utilizando a ferramenta Google Planilhas (Sheets). No decorrer do trabalho, foram catalogados 1.207 exemplares de abelhas, distribuídos em oito gêneros pertencentes à ordem Hymenoptera. A análise dos dados revelou que os principais locais de coleta foram os municípios de Martins, Pau dos Ferros e Portalegre, destacando a importância dessas áreas para o estudo da biodiversidade no semiárido. Além disso, identificou-se ampla variedade de métodos de coleta utilizados, sendo o ninho armadilha o mais frequente entre eles. A coleção foi formada por contribuições de 197 coletores, com participações realizadas entre os anos de 2015 e 2023. Após o processo de organização e digitalização, a coleção encontra-se devidamente atualizada e estruturada em formato digital, permitindo o resgate das informações sobre todos os espécimes de forma prática e acessível. Essa iniciativa contribui para a preservação do acervo, fomenta estudos científicos e promove a conservação da biodiversidade regional.
Derivation of Z-component Nonlinear Force under Wave-particle Interaction Process in Plasma Medium

Published: February 2025

Instabilities in open and closed plasma media can be explained through wave-particle interaction processes. In our work we investigate some features of plasma instabilities in ionosphere on the basis of nonlinear wave-particle interaction process. The accelerated plasma particles may transfer their energy to high frequency plasma waves through modulated waves and these nonresonant waves may be amplified at the expense resonant mode energy in plasma medium through modulated field. In this paper we present expressions of nonlinear force due to wave-particle interaction process in plasma medium under specific conditions.

Bicarbonate ions and pH regulation of Leishmania major promastigotes
Authors: Vieira Lita , Cabantchik Z.I.
Published: July 2002

Leishmania major promastigotes are parasites endowed with a plasma membrane electrogenic H+ pump and anionic channels. These systems have been thought to contribute to pH homeostasis of parasites and environmental adaptation by mediating extrusion of protons which are either generated metabolically or result from exogenous acid loads. In this work we show that HCO3
− transport plays a physiological role in supporting pH regulation of parasites. Intracellular pH (pHi) and the membrane potential (V
m) were assessed fluorometrically with pH sensitive and potentiometric dyes. We show that intracellular acidification, caused either by blocking the pump or the putative anion channel or by depleting Cl− from cells, could be largely overcome by addition of HCO3
−. Likewise, addition of HCO3
− raises the steady state intracellular pH of untreated cells from 6.76 ± 0.01 to 6.98 ± 0.02 and induces membrane hyperpolarization in pump‐inhibited cells. We provide evidence for the involvement of HCO3
− transport systems that subserve pH homeostasis in Leishmania promastigotes. A major anionic pathway which is sensitive to anion transport blockers is apparently conductive in nature and accomodates ions such as HCO3
− and Cl−. In physiological conditions, the primary role of H+ pumping is the generation of a relatively large membrane potential (V
m = −113 ± 4 mV) which subserves electrochemical‐driven uptake of nutrients. The involvement of H+ pumping in physiological pH regulation of promastigotes is apparently of a secondary nature.
Dexamethasone inhibits ozone‐induced gene expression of macrophage inflammatory protein‐2 in rat lung

To address the potential role of the chemokine macrophage inflammatory protein‐2 (MIP‐2) in airway inflammation, we examined whether MIP‐2 may play a role in ozone‐induced neutrophilic inflammation of airways and its modulation by dexamethasone in rat lung. Following ozone exposure, MIP‐2 mRNA expression in the lung peaked at 2 h after exposure and slowly declined thereafter. Dexamethasone suppressed ozone‐induced MIP‐2 mRNA expression and neutrophil accumulation in the lung. We suggest that the MIP‐2 mRNA induction may switch on the neutrophilic influx observed in this model of lung inflammation. Furthermore, the MIP‐2 expression is regulated by dexamethasone which may represent one of the mechanisms by which glucocorticoids exert their potent anti‐inflammatory properties.
Endotoxin and fibrinogen degradation product‐D have different actions on carbohydrate metabolism: role of Kupffer cells

Published: July 2002

The effect of endotoxin‐derived lipopolysaccharide (LPS) and fibrinogen degradation product D (FDPD) on oxygen consumption and glycogenolysis in the perfused rat liver was investigated. 1. Infusion of LPS (100 μg/ml) or FDPD (7 μg/ml) caused a rapid stimulation of oxygen uptake by the perfused liver of 10–12 μmol/g/h. 2. LPS also caused a transient increase in glucose and lactate release into the perfusion medium from endogenous glycogen; however, FDPD was without effect. 3. Destruction of Kupffer cells by GdCl3 pretreatment blocked the effects of LPS and FDPD on oxygen uptake and glycogenolysis. Further, LPS and FDPD had no effect on oxygen consumption by isolated hepatocytes. Therefore, it is concluded that Kupffer cells are involved in the increase of hepatic oxygen consumption and carbohydrate release caused by LPS, most likely via release of PGE2 and PGD2. Since FDPD increased oxygen but not carbohydrate release, it is concluded that it acts via stimulating the release of mediators distinct from those released following LPS infusion.
