May ’68

Much as in other locations around the world, civil uprising, particularly rooted in the activism of young people and students, plagued France during May of 1968. Massive strikes and occupations succeeded in paralysing France’s economy and bringing the country to the verge of a leftist revolution. This book studies the life trajectories of many ordinary protestors during the period, using statistics andpersonal narratives to analyse how this activism arose, its impact on people’s personal and professional lives, and its transmission through familial generations

Jeunes altermondialistes en réseau

National audienceCet article se propose de questionner la « forme réseau » à partir d'une enquête sur trois réseaux militants de jeunes altermondialistes. Le concept de réseau désigne à la fois un mode de coordination particulier et une idéologie du renouvellement des formes de mobilisation (porteuse des valeurs d'hétérogénéité, de transparence et d'horizontalité). L'accent est mis sur l'analyse des rôles et usages des TIC qui sous-tendent le développement de ces formes réticulaires de militantisme ainsi que sur leur influence sur les pratiques militantes

Augmentation de la taille de l’espace de travail opérationnel des robots parallèles en traversant les singularités de Type 2 :Génération de trajectoires optimales et commande avancée

In order to increase the size of the operational workspace of parallel robots (largely reduced by the presence of singularities), the approach proposed in this thesis consists of directly moving a mechanism through those singularities.To do so, the conditions of degeneracy of the dynamic model of parallel robots are first studied. From those conditions, it is possible to create criteria that ensure the non-degeneracy of the mechanism in a singular configuration. This allows the planning of trajectories that go from one aspect of the workspace to another through a singularity, and without anydegeneracy of the dynamic model. In order to track those trajectories, a multi-model computed torque control is presented, coupled with an optimal trajectory planning strategy.Every development presented have been validated in simulation and experimentally on a prototype of a five-bar mechanism designed and manufactured during the thesis.Afin d’augmenter la taille de l’espace de travail opérationnel des robots parallèles (largement réduit par la présence de singularités), cette thèse propose une approche consistant à traverser ces singularités.Pour permettre cette traversée, les conditions de dégénérescence du modèle dynamique des mécanismes parallèles sont d’abord étudiées. Cette étude permet de mettre en place des conditions de non dégénérescence sous forme de critères. En planifiant une trajectoire respectant ces critères, un mécanisme parallèle peut théoriquement traverserune singularité sans que les efforts ne divergent. Un contrôleur basé sur une commande en couples-calculés multi-modèle et dédié à la traversée de singularité, couplé avec une stratégie de planification de trajectoire optimale est par la suite proposé. L’ensemble des travaux présentés est validé en simulation puis expérimentalement sur un prototype de mécanismes à cinq barres développé et conçu durant la thèse

Hollow Y zeolite single crystals: synthesis, characterization and activity in the hydroisomerization of n-hexadecane

International audienceHollow Y zeolite single crystals have been obtained from a conventional NaY zeolite following a three-step process involving a severe dealumination of the zeolite with silicon tetrachloride (step #1), followed by an acid washing under mild conditions (step #2) and finally a selective dissolution of the crystals core in the presence of protective Al species (step #3). Crystals are characterized by the presence of a regular internal cavity with 0.1–0.2 nm thick microporous walls. They contain a relatively low framework Al content but significant amounts of extraframework Al oxide species mainly located on the external surface of the crystals. Hollow crystals have been mixed with a Pt-supported alumina binder and used as catalysts in the hydroisomerization of n-hexadecane. Compared to the corresponding bulk crystals obtained after step #2, their higher activity has been attributed to a better efficiency, directly resulting from the presence of the cavity

Dukungan keluarga, kepatuhan dan pemahaman pasien terhadap diet rendah garam pada pasien dengan hipertensi

Family support, adherence and understanding of a low-salt diets among patients with hypertensiveBackground: Hypertension is a disorder of the blood vessels that results in the supply of oxygen and nutrients carried by the blood blocked to the tissues of the body that needs it. Based on data from the Gedong Air Health Center, it is known that from 2015 to 2018 the incidence of hypertension fluctuated, wherein 2016 it amounted to 1962 cases but in 2017 it increased to 2814 cases and in 2018 the incidence of hypertension was 3102 cases.Purposes: Knowing the relationship of family support, adherence, and understanding of a low-salt diet among patients with hypertensiveMethod: A quantitative research designed with analysis by cross-sectional approach and the population was patients with hypertensive with a sample of 139 as respondents by simple random sampling. Collecting data by questionnaires and Analysing data used Univariate and Bivariate (Chi-Square).Results: Finding that the patient has negative family support was 58.7%, the patient was noncompliant to a low-salt diet .57.2%, and few patients have an understanding of a low-salt diet. There is a relationship between the understanding of a low-salt diet (p-value = 0.000), family support (p-value = 0.032) and compliance with a low-salt diet among patients with hypertensive.Conclusion: There is a relationship of understanding of low-salt diets, family support and compliance to a low-salt diet among patients with hypertensive. Suggestions for  health workers in providing health education to families and patients with hypertensive about the importance of low salt diets in the management of hypertensionKeywords: Family support; Compliance; Understanding; Low-salt diet; Hypertensive. Pendahuluan: Hipertensi merupakan suatu gangguan pada pembuluh darah yang mengakibatkan suplai oksigen dan nutrisi yang dibawa oleh darah terhambat sampai ke jaringan tubuh yang membutuhkanya. Berdasarkan data dari Puskesmas Gedong Air, diketahui bahwa dari tahun 2015 – 2018 kejadian hipertensi mengalami fluktuatif , dimana tahun 2016 sebesar 1962 kasus namun di tahun 2017 mengalami peningkatan menjadi sebesar 2814 kasus dan di tahun 2018 kejadian hipertensi sebesar 3102 kasus.Tujuan: Diketahui hubungan dukungan keluarga, kepatuhan dan pemahaman  pasien terhadap diet rendah garam  pada pasien dengan hipertensiMetode: Penelitian kuantitatif dengan rancangan analitik dan pendekatan cross sectional, populasinya seluruh pasien dengan hipertensi dengan sampel sebanyak 139 dengan simple random sampling. Pengumpulan data dengan kuesioner data dianalisa secara univariate dan bivariate (chi square)Hasil: Diketahui dukungan keluarga kategori negatif 58,7%, responden tidak patuh 57,2%, dan sedikit yang memiliki pemahaman diet rendah garam  (p-value=0,000), ada hubungan antara dukungan keluarga (p-value = 0,032), kepatuhan dan pemahaman  pasien terhadap diet rendah garam  pada pasien dengan hipertensiSimpulan: Ada hubungan dukungan keluarga, kepatuhan dan pemahaman  pasien terhadap diet rendah garam  pada pasien dengan hipertensi. Saran bagi petugas kesehatan puskesmas dalam memberikan pendidikan kesehatan kepada keluarga dan pasien dengan hipertensi tentang pentingnya diet rendah garam

The emotional self: Embodiment, reflexivity, and emotion regulation

YesCurrent dominant trends in the biological and psychological sciences tend to put emphasis on the role of the brain, cognition, and consciousness in realising emotional states and attempting to regulate them. In this article, I suggest an alternative approach with the idea that emotions emerge within social relations and give meaning and value to the situations in which we are located. Humans are understood as embodied emotional selves for who thought and emotion are intertwined. However, individuals can get caught in obsessive and compulsive thinking and feeling traps where the self loses touch with its emotions, and because of this also loses contact with the social situation and the ability to skilfully navigate it. In such circumstances, the self gets overwhelmed by emotion and loses its poise in the social setting. I consider Buddhist meditation as a technique through which people can develop a more reflexive emotional self, where reflexivity is not about control of emotion but owning one's feelings and being able to respond more sensitively and skilfully in various situations
