Staphylococcus aureus is a normal flora of the skin and mucous membranes in humans, it can cause human infection in the form of boils. One example of antimicrobials that can be obtained from nature is the flower plant because it contains active substances, namely saponins, flavonoids, and tannins. To increase the effectiveness and convenience of using bungur leaves, it is necessary to formulate it in a more practical form such as a preparation. This study aims to identify the active fraction of the leaf extract of bungur (Lagerstroemia speciosa L. Pers) in boils ointment against Staphylococcus aureus bacteria. The extraction method was used the maceration method, which was followed by the preparation of a boil ointment formulation, then tested against the Staphylococcus aureus bacteria. The diameter of the resistance formed was measured and statistically analyzed using the Completely Randomized Design (CRD) method. The results showed that the average resistance diameter of 1% bungur leaf ointment was 11.5 mm, 5% was 12.7 mm, 10% was 15.8 mm, and positive control was 16.5 mm. It was concluded that the effective concentration of bungur leaf extract in the ointment preparation in inhibiting the growth of Staphylococcus aureus was 1%.

Published: April 2022

Abstract
Here we present new constraints on Uranus’s and Neptune’s externally sourced stratospheric water abundance using disk-averaged observations of the 557 GHz emission line from Herschel’s Heterodyne Instrument for the Far-Infrared. Derived stratospheric column water abundances are

0.54

0.26

× 1014 cm−2 for Uranus and

1.9

−

+
0.2

×1014 cm−2 for Neptune, consistent with previous determinations using ISO-SWS and Herschel-PACS. For Uranus, excellent observational fits are obtained by scaling photochemical model profiles or with step-type profiles with water vapor limited to ≤0.6 mbar. However, Uranus’s cold stratospheric temperatures imply a ∼0.03 mbar condensation level, which further limits water vapor to pressures ≤0.03 mbar. Neptune’s warmer stratosphere has a deeper ∼1 mbar condensation level, so emission-line pressure broadening can be used to further constrain the water profile. For Neptune, excellent fits are obtained using step-type profiles with cutoffs of ∼0.3–0.6 mbar or by scaling a photochemical model profile. Step-type profiles with cutoffs ≥1.0 mbar or ≤0.1 mbar can be rejected with 4σ significance. Rescaling photochemical model profiles from Moses & Poppe to match our observed column abundances implies similar external water fluxes for both planets:

+
4.0

× 104 cm−2 s−1 for Uranus and

12.7

−
2.0

+
1.3

×104 cm−2 s−1 for Neptune. This suggests that Neptune’s ∼4 times greater observed water column abundance is primarily caused by its warmer stratosphere preventing loss by condensation, rather than by a significantly more intense external source. To reconcile these water fluxes with other stratospheric oxygen species (CO and CO2) requires either a significant CO component in interplanetary dust particles (Uranus) or contributions from cometary impacts (Uranus, Neptune).

This study surveyed the vascular flora present in 455 forest wetlands in South Korea to provide baseline data for conservation, management, and monitoring and to support preparation for climate change. The survey period was from April 2015 to November 2019. The vascular flora of 455 forest wetlands were identified and were found to consist of 143 families, 582 genera, 1,246 species, 26 subsp., 104 var., 12 f., and 1,388 individual taxa. 8 taxa were identified as Grade II endangered wild plants, 220 taxa were identified as northern lineage plants of the Korean Peninsula, 66 taxa were endemic to the Korean Peninsula, and 94 taxa were rare plants as designated by the Korea Forest Service. Among them, 8 taxa were Critically Endangered species, 10 taxa were Endangered species, 31 taxa were Vulnerable species, 31 taxa were Least Concern species, and 14 taxa were Data Deficient species. Further, 411 taxa were floristic target plants, of which 17 taxa were classified as grade V, 70 taxa as grade IV, 110 taxa as grade III, 90 taxa as grade II, and 29 taxa as grade I. There were 64 invasive alien plant taxa. 18 of these species were classed as Widespread species, 9 taxa were Serious Spread species, 13 taxa were Spread Risk species, 18 taxa were Spread Concern species, and 6 taxa were Continuing Spread species. According to wetland preference, 152 taxa (11.0%) were obligate wetland plants, 138 taxa (9.9%) were facultative wetland plants, and 177 (12.77%) taxa were facultative plants. Additionally, 198 taxa (14.3%) were facultative upland plants, and 723 taxa (52.1%) were obligate upland plants.

L’avènement de l’économie sociale et solidaire : aménagement à la marge ou reconfiguration de l’économie sociale
Authors: Laville Jean-Louis 
Published: April 2022

Une mise en perspective historique permet de se demander si l’ESS est un aménagement à la marge ou une reconfiguration de l’économie sociale. L’associationisme solidaire de la première partie du XIX e siècle est une manifestation utopiste ayant débouché sur un échec ou une tentative d’articulation du mouvement social avec la mise en œuvre d’activités économiques. Plus récemment, l’économie solidaire peut être considérée comme une simple réaction à la montée du chômage et de l’exclusion ou comme une résurgence dans d’autres conditions de l’associationnisme solidaire. L’analyse de ces bifurcations amène à deux scénarios, soit l’économie solidaire n’est qu’une adjonction à la marge de l’économie sociale qui demeure un regroupement d’entreprises collectives, soit l’ESS dépasse le rassemblement d’entreprises pour constituer une socio-économie solidariste.
La visioconférence ou la déliaison du lien transférentiel institutionnel en secteur médico-social adulte
Authors: Passerini Mélanie , Barrer Laurence 
Published: April 2022

Depuis le début de la pandémie Covid-19, nombre de professionnels à leur domicile ont eu recours aux visioconférences par VoIP (Voice over Internet Protocol) pour assurer la continuité de réunion en équipe et maintenir le lien groupal. Mais qu’en est-il de la permanence du lien transférentiel groupal ? Cette nouvelle pratique masque-t-elle, accentue-t-elle ou délite-t-elle le lien transférentiel ? Nous avons constaté l’émergence de mécanismes d’évitement et de dissociation dans les réunions d’équipes institutionnelles ou d’analyses des pratiques professionnelles à l’origine du surgissement de la pulsion agressive qui aurait été auparavant déchargée dans la réalité de la confrontation physique. Chaque sujet issu d’équipes dysfonctionnantes se sent protégé par la fonction médiatrice et pare-excitative que devient l’écran au détriment de la régulation par le groupe. La déliaison pulsionnelle attaque les liens transférentiels, pervertit les relations institutionnelles et semble faire disparaître l’unité du groupe si cette pratique devenait systématique.
La créativité groupale durant le premier confinement : une modalité de traitement d’un traumatisme partagé ?
Authors: Vollon Clarisse , Gimenez Guy 
Published: April 2022

Nous proposons dans cet article un travail de recherche autour de la créativité groupale suite aux mesures de confinement qui ont touché la population française de mars à mai 2020. En nous interrogeant sur l’impact de ces mesures sur des environnements groupaux déjà formés, nous formulons deux hypothèses. Premièrement, l’annonce des mesures de confinement de notre population a provoqué un état de saisissement créateur dans des configurations de liens institués. Ensuite, l’enveloppe psychique de ces groupes a permis l’émergence et le soutien de la créativité groupale. Pour étayer nos propos, nous nous appuierons sur l’analyse d’entretiens non directifs et semi-directifs ainsi que l’enregistrement des séances de travail d’une compagnie de danse contemporaine effectuées via la plateforme Zoomâ durant toute la période de confinement.

To create an international recommendation concerning the release of alkalis, test method AAR-8 was developed within the scope of RILEM TC 258-AAA activities. The first round robin test was performed using five aggregate types, and further investigation was conducted as RRT2, leading to the final version of the AAR-8 recommendation. Five aggregates with different mineralogies and origins were immersed in specific volumes of NaOH or KOH solutions with excess calcium hydroxide maintained 38 °C and 60 °C respectively. Samples of the immersion test solution were removed at intervals of 2, 6, 13, 26, and 52 weeks by pipetting and chemically analyzed for NaOH or KOH test solutions. The amount of alkali released was expressed in grams of Na2O, K2O, and Na2Oe per kilogram of the respective aggregate. The results obtained are presented. Based on the data, several changes to the original version of the test method are proposed.

Abstract
Understanding the generation of immunity to SARS-CoV-2 in lymphoid tissues draining the site of infection has implications for immunity to SARS-CoV-2. We performed tonsil biopsies under local anesthesia in 19 subjects who had recovered from SARS-CoV-2 infection 24–225 d previously. The biopsies yielded &gt;3 million cells for flow cytometric analysis in 17 subjects. Total and SARS-CoV-2 spike-specific germinal center B cells, and T follicular helper cells, were readily detectable in human tonsils early after SARS-CoV-2 infection, as assessed by flow cytometry. Responses were higher in samples within 2 mo of infection but still detectable in some subjects out to 7 mo following infection. We conclude the tonsils are a secondary lymphoid organ that develop germinal center responses to SARS-CoV-2 infection and could play a role in the long-term development of immunity.
