Haryani (2012, 2018) di wilayah pesisir Provinsi Sumatera Barat dari tahun 2003-2016 telah terjadi bencana abrasi pantai dan akresi di 32 titik. Pada kurun waktu 13 tahun tersebut telah terjadi abrasi pantai seluas 732.69 ha dan akresi pantai seluas 55,4 ha. Bencana abrasi pantai menyebabkan berkurangnya daratan pantai yang cukup besar yaitu rata-rata 56,3 ha/tahun, sedangkan penambahan daratan pantai/pesisir hanya 4,26 ha/tahun. Penelitian ini bertujuan untuk menemukan tingkat kerentanan abrasi pantai di Kecamatan Koto Tangah Kota Padang. Parameter fisik, sosial, ekonomi, dan lingkungan dianalisis dengan menggunakan metode skoring sesuai Perka BNPB No. 2 Tahun 2012. Hasil penelitian didapat tingkat kerentanan Sedang berada di 2 kelurahan, yaitu Kelurahan Pasie Nan Tigo dan Kelurahan Parupuk Tabing dengan indek 1,74. Upaya mitigasi yang dilakukan adalah pengaturan kepadatan bangunan, pemanfaatan lahan harus dibatasi agar tidak terjadi kerugiaan lahan yang lebih banyak/luas dan memanfaan lahan dengan memperhatikan pola ruang/peruntukan lahan sebagaimana yang tertuang dalam RTRW Kota Padang. Tingkat kerentanan Rendah berada di Kelurahan Bungo Pasang dengan indek 1. Upaya mitigasi bencana abrasi dan araahan penataan ruang yang dapat dilakukan pada tingkat kerentanan rendah ini adalah mempertahankan guna lahan dengan memperhatikan pola ruang/peruntukan lahan/ruang sebagaimana yang tertuang dalam RTRW Kota Padang.

Abstract
We explore the connection between the γ-ray and radio emission in the jet of the blazar 0716+714 by using 15, 37, and 230 GHz radio and 0.1–200 GeV γ-ray light curves spanning 10.5 yr (2008–2019). We find significant positive and negative correlations between radio and γ-ray fluxes in different time ranges. The time delays between radio and γ-ray emission suggest that the observed γ-ray flares originated from multiple regions upstream of the radio core, within a few parsecs from the central engine. Using time-resolved 43 GHz Very Long Baseline Array maps we identified 14 jet components moving downstream along the jet. Their apparent speeds range from 6c to 26c, and they show notable variations in their position angles upstream from the stationary component (∼0.53 mas from the core). The brightness temperature declines as a function of distance from the core according to a power law that becomes shallower at the location of the stationary component. We also find that the periods at which significant correlations between radio and γ-ray emission occur overlap with the times when the jet was oriented to the north. Our results indicate that the passage of a propagating disturbance (or shock) through the radio core and the orientation of the jet might be responsible for the observed correlation between the radio and γ-ray variability. We present a scenario that connects the positive correlation and the unusual anticorrelation by combining the production of a flare and a dip at γ-rays by a strong moving shock at different distances from the jet apex.

Abstract
The Kodaikanal Observatory has provided long-term synoptic observations of chromospheric activities in the Ca ii K line (393.34 nm) since 1907. This article investigates temporal and periodic variations of the hemispheric Ca–K-index time series in the low-latitude zone (±40°), utilizing the recently digitized photographic plates of Ca–K images from the Kodaikanal Observatory for the period of 1907–1980. We find that the temporal evolution of the Ca–K index differs from one hemisphere to another, with the solar cycle peaking at different times in the opposite hemisphere, except for cycles 14, 15, and 21, when the phase difference between the two hemispheres was not significant. The monthly averaged data show a higher activity in the northern hemisphere during solar cycles 15, 16, 18, 19, and 20, and in the southern hemisphere during cycles 14, 17, and 21. We notice an exponentially decaying distribution for each hemisphere’s Ca–K index and the whole solar disk. We explored different midterm periodicities of the measured Ca–K index using the wavelet technique, including Rieger-type and quasi-biennial oscillations on different timescales present in the time series. We find a clear manifestation of the Waldmeier effect (stronger cycles rise faster than the weaker ones) in both the hemispheres separately and the whole disk in the data. Finally, we have found the presence of the Gnevyshev gap (time interval between two cycle maxmima) in both the hemispheric data during cycles 15 to 20. Possible interpretations of our findings are discussed with the help of existing theoretical models and observations.
Le tamaris au siècle des Lumières
Authors: Burgel Élias 
Published: January 2022

Dans un mémoire envoyé en 1778 à l’Académie de Caen, le botaniste languedocien Pierre-Joseph Amoreux projette la mise en place de pépinières de tamaris pour valoriser économiquement les terres littorales mouvantes du royaume de France. Son utopie botanique invite à considérer, par-delà la césure entre nature et culture, l’historicité de cet arbrisseau des incultes saumâtres. Bien qu’il semble constituer un élément immuable des décors lagunaires du bas Languedoc et bien que situé hors des champs, le tamaris est mis en ressource durant l’époque préindustrielle : employé comme combustible, comme fourrage ou comme matériau, il fait l’objet de différentes pratiques de ménagement en vue de sa conservation. De leur côté, les ingénieurs du siècle des Lumières considèrent de plus en plus ce végétal, adjuvant traditionnel de micro-aménagements littoraux, comme un outil d’ aménagement . S’inspirant de savoirs empiriques, ils l’intègrent progressivement à leur art. Au total, le mariage de l’histoire environnementale et de l’histoire rurale permet de considérer cet arbrisseau comme un être hybride.
CCUS et charbon ‒ Existe-t-il encore des opportunités de développement pour les centrales au charbon ?
Authors: Cornot-Gandolphe Sylvie 
Published: January 2022

Alors que de plus en plus de gouvernements s’engagent sur la voie de la neutralité carbone d’ici à 2050, sortent du charbon et accélèrent le développement des énergies renouvelables, qu’en est-il des développements CCUS sur les centrales au charbon ? Dans cet article, nous répondons à cette question en expliquant tout d’abord les raisons de l’échec de la première vague de projets CCUS des années 2000, qui était axée principalement sur la capture des émissions des centrales au charbon. Puis, nous examinons l’application du CCUS aux centrales au charbon dans le contexte du regain d’intérêt pour le CCUS depuis 2018. En particulier, les politiques et projets de CCUS dans trois pays clés (États-Unis, Chine et Inde) sont étudiés. Cette analyse montre que le CCUS reste incontournable en Asie pour décarboner un mix électrique dominé par le charbon. Mais sa contribution requiert un signal prix du carbone et des efforts de recherche pour réduire les coûts de la capture du CO 2 . Cette contribution pourrait néanmoins se réduire face à la fermeture anticipée des centrales de ce type, leur repositionnement sur certaines technologies de rupture et les progrès réalisés en la matière.
Les opportunités offertes par le CCUS pour décarboner l’industrie française
Authors: Legait Benoit 
Published: January 2022

Dans l’industrie, le captage et le stockage du CO 2 intéressent surtout la sidérurgie et l’industrie cimentière, et permettent des émissions « négatives » pour le gaz carbonique issu de la combustion de la biomasse. En 2050, une quinzaine de Mt CO 2eq devraient être captées et stockées, sous réserve de lever plusieurs freins. L’utilisation de CO 2 semble surtout prometteuse pour favoriser la croissance des cultures et pour la fabrication d’éthanol ; elle nécessite encore d’accroître les efforts en matière de R&D.
Pas de décarbonation du secteur aérien sans la capture et le stockage du CO 2
Authors: Vignon Dominique 
Published: January 2022

Les émissions de gaz à effet de serre (GES) de l’aviation augmentent de 7 % par an. L’International Air Transport Association (IATA), qui fédère les acteurs du secteur, a annoncé, en septembre 2021, viser l’objectif « Zéro émission nette » en 2050. Outre une meilleure maîtrise de la croissance du trafic, la réduction des émissions de GES passera essentiellement par la mobilisation de carburants substituables au kérosène, dénommés les SAF (synthetic/sustainable aviation fuels) ; l’hydrogène présentant un potentiel limité d’ici à 2050. Or, ces combustibles restent marginalement carbonés, et leur disponibilité n’est pas suffisante pour couvrir tous les besoins du trafic. On estime donc que l’aviation devra recourir à des puits de carbone dès la décennie 2020, et que les émissions à compenser devraient atteindre 1,5 Gt de CO 2 par an en 2050. La certification des émissions séquestrées est délicate, d’où la nécessité de la mise en place d’une organisation indépendante de l’industrie. Le besoin en stockage des émissions françaises pour atteindre l’objectif « Zéro émission nette » dépasse les objectifs de la stratégie nationale bas carbone (SNBC).
Le stockage du carbone dans les sols
Authors: Chenu Claire , Chotte Jean-Luc , Luu Paul 
Published: January 2022

Les sols du monde représentent un très important stock de carbone, environ 2 400 Gt de carbone, sous forme de matières organiques. Une perte, même faible, de ces stocks aurait des conséquences désastreuses pour le climat, alors qu’une petite augmentation de ceux-ci pourrait contribuer à atténuer le changement climatique. Cet article présente les caractéristiques de ce stockage, les pratiques et usages des sols qui peuvent être mobilisés pour protéger les stocks de carbone des sols existants et les augmenter, leur performance, ainsi que les nombreux bénéfices associés en termes de fertilité des sols et donc de sécurité alimentaire, d’adaptation au changement climatique et de services écosystémiques. Mais aussi les barrières à l’implémentation de la technologie considérée et les risques associés. Même si le stockage du carbone dans les sols est une technologie d’émissions négatives à bas coût, largement promue par l’Initiative internationale « 4 pour 1000 », des mesures incitatives sont nécessaires pour permettre d’accroître sa mise en œuvre.
Portrait(s) de l’artiste en pédagogue

La problématique éducative des arts et la place qu’y occupe l’artiste ne peuvent être clarifiées sans que soient démêlés les fils dans lesquels elles sont prises. Il en va de même de la préservation de la perspective émancipatrice de l’éducation artistique. Cette problématique est le plus souvent abordée du point de vue de l’école. Il est pourtant nécessaire, et même d’abord nécessaire, de l’envisager du point de vue de l’art et des artistes. L’intervention des artistes eux-mêmes dans le champ éducatif ne prend tout son sens que si on la considère également comme un développement interne au champ de l’art lui-même. L’histoire de l’art moderne croise celle de l’éducation et de l’enfance. En se situant à ce croisement, on peut comprendre la démarche artistique dans sa singularité, telle qu’elle se déploie dans ce que Rancière appelle « le régime esthétique des arts », comme démarche éducative. C’est alors sous les traits d’un maître ignorant provisoire que l’artiste ouvre dans l’école la possibilité de moments hétérotopiques.

Abstract
Deficiency in the clearance of cellular debris is a major pathogenic factor in the emergence of autoimmune diseases. We previously demonstrated that mice deficient for scavenger receptor class F member 1 (SCARF1) develop a lupus-like autoimmune disease with symptoms similar to human systemic lupus erythematosus (SLE), including a pronounced accumulation of apoptotic cells (ACs). Therefore, we hypothesized that SCARF1 will be important for clearance of ACs and maintenance of self-tolerance in humans, and that dysregulation of this process could contribute to SLE. In this article, we show that SCARF1 is highly expressed on phagocytic cells, where it functions as an efferocytosis receptor. In healthy individuals, we discovered that engagement of SCARF1 by ACs on BDCA1+ dendritic cells initiates an IL-10 anti-inflammatory response mediated by the phosphorylation of STAT1 and STAT3. Unexpectedly, there was no significant difference in SCARF1 expression in samples of patients with SLE compared with healthy donor samples. However, we detected anti-SCARF1 autoantibodies in 26% of patients with SLE, which was associated with dsDNA Ab positivity. Furthermore, our data show a direct correlation of the levels of anti-SCARF1 in the serum and defects in the removal of ACs. Depletion of Ig restores efferocytosis in SLE serum, suggesting that defects in the removal of ACs are partially mediated by SCARF1 pathogenic autoantibodies. Our data demonstrate that human SCARF1 is an AC receptor in dendritic cells and plays a role in maintaining tolerance and homeostasis.
Combined effect of reduced glutathione and ulinastatin on the expressions of IL-6, sIL-6 and sgp130 in peripheral blood of paraquat-poisoned patients
Authors: Wang Jianghai , Sun Hongting , Fan Lihua , Si Xuepeng , Li Liang , Han Wang 
Published: January 2022

Purpose: To investigate the effect of reduced glutathione and ulinastatin on the expressions of interleukin-6 (IL-6), soluble interleukin-6 receptor (sIL-6R), and soluble glycoprotein 130 (sgp130) in peripheral blood of paraquat-poisoned patients.
Methods: In this retrospective study, 88 patients with paraquat poisoning admitted to Dongying People's Hospital, Dongying, China from February 2017 to October 2020 were divided into control group (n = 40) and study group (n = 48), based on treatment type. The control group received conventional treatments, while the study group was given reduced glutathione in combination with ulinastatin. Treatment efficacy and peripheral blood expression levels were compared.
Results: Compared to the control group, curative effect was significantly higher in the study group (p < 0.05). The expression levels of IL-6, sIL-6R, and sgp130 in the peripheral blood at the early, middle and late periods in the study group were markedly lower. The number of patients with flake-like or dotted opacity, increased lung texture, pleural effusion and ground glass opacity in the study group during the early period was lower (p < 0.05). Moreover, the number of patients with pulmonary edema, fibrous cord, pleural effusion, ground glass opacity and reticular opacity during the middle period was markedly lower for the study group, while the population of patients with honeycomb lung, fibrous cord, nodules and reticular opacity in the study group was higher t (p < 0.05).
Conclusion: A combination of reduced glutathione and ulinastatin produces significant therapeutic effect on paraquat poisoning by down-regulating the serum expressions of IL-6, sIL-6 and sgp130, inhibiting inflammation, and mitigating pulmonary lesions.
Protective effect of luteolin against oxidative stress during hypoxic ischemia-induced neuronal damage in neonatal rats
Authors: Cao Weihong , Luo Jun , Peng Jingwei , Zhu Xiaoxia , Li Shigang , Ma Jilong 
Published: January 2022

Purpose: To investigate the neuroprotective efficacy of plant polyphenol luteolin against hypoxic ischemia (HI)-induced neuronal injury in neonatal rat pups.
Methods: Postnatal rat pups (aged 7 days) were subjected to HI insult, and then treated with luteolin at a dose of 1.2 mg/kg body weight (bwt) for up to 4 days after HI injury. Following the sacrifice of the pups, the brain tissues were subjected to histological examination (H & E staining), as well as biochemical and antioxidant assays. Moreover, levels of cell death regulator proteins were determined by enzyme-linked immunosorbent assay (ELISA).
Results: There was significant increase in the tissue levels of reactive oxygen species (ROS) and malondialdehyde (MDA), but marked decrease in mitochondrial membrane potential (ΔΨm) in the HI rat pups (p < 0.05). Furthermore, HI decreased the brain tissue levels of the antioxidants, SOD, CAT, GPX and GSH, in the postnatal pups. However, luteolin treatment significantly reversed the abnormal increase in the levels of ROS and MDA, but reduced the loss in mitochondrial membrane potential (ΔΨm), while increasing the levels of SOD, CAT GPX and GSH (p < 0.05). Furthermore, HI significantly increased the brain expression levels of the pro-apoptotic markers, i.e., cytosolic cytochrome C (cyt c), caspase-3 and caspase-9 in the pups exposed to HI, indicating neuronal cell death. However, the HI- induced increase in the expression levels of these pro-apoptotic factors was reduced by luteolin treatment.
Conclusion: These results suggest that luteolin protects postnatal rat pups from hypoxic ischemic- induced brain damage (neuronal cell death) due to its antioxidant and free radical-scavenging activities. Therefore, luteolin may be a potential neuroprotective agent in the management of HI-associated complications.
Effect of curcumin on the viability of SKOV3 cells and its probable mechanism of action
Authors: Dan Wang , Cheng Xu , Fei-Fei Zhang , Bao-Jin Zeng 
Published: January 2022

Purpose: To study the influence of curcumin on the survival of SKOV3 cells and the potential molecular mechanism of action.
Methods: SKOV3 cell proliferation was measured using MTT assay. Gene expression levels were assayed using QRT-PCR assay, while protein expression was determined with western blotting.
Results: Cell viability was reduced by curcumin at doses of 20, 40 and 80 μM (p < 0.05) in a dose-based fashion. Protein expression levels of Bax, caspase-3 and caspase-9 were upregulated by curcumin, while Bcl-2 protein level was downregulated (p < 0.05).
Conclusion: These results demonstrate that curcumin inhibits cell proliferation by promoting the protein expressions of pro-apoptotic genes (Bax, caspase-3 and caspase-9) while suppressing Bcl-2 protein level. Therefore, curcumin might be a novel alternative therapy for ovarian cancer.
