Abstract
The observed correlation between outer giant planets and inner super-Earths is emerging as an important constraint on planet formation theories. In this study, we focus on Kepler-167, which is currently the only system known to contain both inner transiting super-Earths and a confirmed outer transiting gas giant companion beyond 1 au. Using long-term radial velocity monitoring, we measure the mass of the gas giant Kepler-167e (P = 1071 days) to be

J, thus confirming it as a Jupiter analog. We refit the Kepler photometry to obtain updated radii for all four planets. Using a planetary structure model, we estimate that Kepler-167e contains 66 ± 19 M
⊕ of solids and is significantly enriched in metals relative to its solar-metallicity host star. We use these new constraints to explore the broader question of how systems like Kepler-167 form in the pebble accretion framework for giant planet core formation. We utilize simple disk evolution models to demonstrate that more massive and metal-rich disks, which are the most favorable sites for giant planet formation, can also deliver enough solids to the inner disk to form systems of super-Earths. We use these same models to constrain the nature of Kepler-167's protoplanetary disk and find that it likely contained ≳300 M
⊕ of dust and was ≳40 au in size. These values overlap with the upper end of the observed dust mass and size distributions of Class 0 and I disks and are also consistent with the observed occurrence rate of Jupiter analogs around Sun-like stars.
Excitation and Damping of Slow Magnetosonic Waves in Flaring Hot Coronal Loops: Effects of Compressive Viscosity
Authors: Ofman Leon , Wang Tongjiang 
Published: February 2022

Abstract
Slow magnetosonic waves associated with flares were observed in coronal loops by Solar and Heliospheric Observatory/Solar Ultraviolet Measurements of Emitted Radiation, Solar Dynamics Observatory/Atmospheric Imaging Assembly in various EUV bandpasses, and other instruments. The excitation and damping of slow magnetosonic waves provides information on the magnetic, temperature, and density structure of the loops. Recently, it was found using 1.5D models that the thermal conduction is suppressed and compressive viscosity is enhanced in hot (T > 6 MK) flaring coronal loops. We model the excitation and dissipation of slow magnetosonic waves in hot coronal loops with realistic magnetic geometry, enhanced density, and temperature (compared to background corona) guided by EUV observations using a 3D magnetohydrodynamic (MHD) visco-resistive model. The effects of the compressive viscosity tensor component along the magnetic field are included with classical and enhanced viscosity coefficient values for the first time in a 3D MHD coronal loop model. The waves are excited by a velocity pulse at the footpoint of the loop at the coronal lower boundary. The modeling results demonstrate the excitation of the slow magnetosonic waves and nonlinear coupling to other wave modes, such as the kink and fast magnetosonic. We find significant leakage of the waves from the hot coronal loops with a small effect of viscous dissipation in cooler (6 MK) loops, and more significant effects of viscous dissipation in hotter (10.5 MK) coronal loops. Our results demonstrate that nonlinear 3D MHD models are required to fully account for the various wave couplings, damping, standing wave formation, and viscous dissipation in hot flaring coronal loops. Our viscous 3D MHD code provides a new tool for improved coronal seismology.

Abstract
The Multi-slit Solar Explorer (MUSE) is a proposed mission composed of a multislit extreme ultraviolet (EUV) spectrograph (in three spectral bands around 171 Å, 284 Å, and 108 Å) and an EUV context imager (in two passbands around 195 Å and 304 Å). MUSE will provide unprecedented spectral and imaging diagnostics of the solar corona at high spatial (≤0.″5) and temporal resolution (down to ∼0.5 s for sit-and-stare observations), thanks to its innovative multislit design. By obtaining spectra in four bright EUV lines (Fe ix 171 Å, Fe xv 284 Å, Fe xix–Fe xxi 108 Å) covering a wide range of transition regions and coronal temperatures along 37 slits simultaneously, MUSE will, for the first time, “freeze” (at a cadence as short as 10 s) with a spectroscopic raster the evolution of the dynamic coronal plasma over a wide range of scales: from the spatial scales on which energy is released (≤0.″5) to the large-scale (∼170″ × 170″) atmospheric response. We use numerical modeling to showcase how MUSE will constrain the properties of the solar atmosphere on spatiotemporal scales (≤0.″5, ≤20 s) and the large field of view on which state-of-the-art models of the physical processes that drive coronal heating, flares, and coronal mass ejections (CMEs) make distinguishing and testable predictions. We describe the synergy between MUSE, the single-slit, high-resolution Solar-C EUVST spectrograph, and ground-based observatories (DKIST and others), and the critical role MUSE plays because of the multiscale nature of the physical processes involved. In this first paper, we focus on coronal heating mechanisms. An accompanying paper focuses on flares and CMEs.
Impact of the Inverted Internal Limiting Membrane Flap Diameter on Large Idiopathic Macular Hole Closure: Comparative Randomized Study
Authors: Elwan Mohamed M. , Hagras Sherein M. 
Published: February 2022

BACKGROUND AND OBJECTIVE:
To study the impact of the size of internal limiting membrane inverted flap on the rate and timing of large idiopathic macular hole (MH) closure.

PATIENTS AND METHODS:

A prospective randomized comparative study included patients with large idiopathic MH. Eligible eyes underwent pars plana vitrectomy with either inverted small flap (
SF
< 2 disc diameters) or inverted large flap (LF from 2 to 4 disc diameters). The primary outcome measure included the rate of MH closure at the sixth month. Secondary outcome measures included the timing of MH closure and best-corrected visual acuity.

RESULTS:
Twenty-five eyes were included: 13 in the SF group and 12 in the LF group. At 6 months, the rate of closure was 84.6% in the SF group and 91.6% in the LF group, with no significant difference. Timing of closure was significantly shorter with LF, with better postoperative best-corrected visual acuity.

CONCLUSION:
LF offered a shorter duration for closure with better visual outcomes in large idiopathic MH.

Pierre Batcheff, les Lacoudems, et les aventures d’Émile-Émile
Authors: Powrie Phil , Rebillard Éric 
Published: February 2022

Pierre Batcheff, connu aujourd’hui principalement pour son rôle dans Un chien andalou, fut l’un des jeunes premiers les plus en vue des années 1920. Il est mort jeune, en 1932, d’une overdose, au moment où il allait devenir ce dont il rêvait : metteur en scène. Nous esquissons ici sa carrière fulgurante, appuyant surtout, à la lumière de documents récemment trouvés, sa collaboration avec les frères Prévert pour un film qui avait pour titre Émile-Émile, ou le trèfle à quatre feuilles. Le film ne vit pas le jour, mais le scénario de Batcheff, sur une idée originale de Jacques Prévert, témoigne de l’esprit surréaliste partagé par les Lacoudems dont ils faisaient partie.
Le Cinématographe contre l’Art : Ciné-conférence donnée par Marcel L’Herbier au Collège de France, le 7 juin 1923
Authors: Côme Arthur 
Published: February 2022

Entre 1920 et 1926 Marcel L’Herbier multiplie conférences et articles autour du thème de la confrontation entre le cinéma et les arts institués. Loin de demander à prendre place parmi eux, le cinématographe viendrait les périmer et jeter les bases nouvelles de l’art présent et à venir. La conférence que le cinéaste donne au Collège de France en 1923 est au centre de cette campagne qui se déploie, outre Paris, à Bruxelles, Lausanne et Genève à la faveur de la présentation de l’Inhumaine. Ces interventions innovent également sur plusieurs plans, en proposant un mélange de projection et de prise de parole : non seulement des extraits de films venant exemplifier les thèses de l’orateur, mais une mise en forme de la performance elle-même. En retrouvant dans le fonds L’Herbier de la BnF le manuscrit de cette conférence, on en propose ici une édition qui diffère des publications de l’époque et des différentes variantes qui en furent données dont plusieurs sont reprises ici, ainsi que des textes ultérieurs mal connus du cinéaste venant nourrir un dossier sur la pensée du cinéma de Marcel L’Herbier.
La question de l’influence de la Qādiriyya sur les débuts du califat de Ḥamdallāhi, à l’épreuve de nouvelles sources
Authors: Salvaing Bernard 
Published: February 2022

Les auteurs de l’époque coloniale (Marty ou Hampâté Bâ) ont analysé le mouvement mené par Aḥmad Lobbo en 1818 en projetant de façon anachronique sur une réalité passée le paysage confrérique de leur époque. D’où leur attribution du mouvement à l’influence de la Qādiriyya et des Kounta. L’étude des sources locales anciennes conduit à écarter cette vision. La naissance de l’État islamique du Māsina paraît plutôt procéder d’un revivalisme, prenant comme référence la politique islamique de l’empereur songhay Askiyā Muḥammad (m. 1538) conseillé par le prédicateur al-Maġīlī, cherchant à intégrer en profondeur l’islam dans la vie sociale et culturelle de l’Empire. Il faut aussi prendre en compte la présence de longue date, dans toute l’Afrique de l’Ouest musulmane, d’une culture islamique privilégiant le fiqh et le taṣawwuf, mais sans enracinement confrérique institutionnalisé. Par ailleurs, avant la Tiǧāniyya d’al-Ḥāǧǧ ‘Umar, le renouveau islamique observé aux xviie et xviiie siècles dans le reste du monde musulman n’a guère eu d’impact sur l’Ouest africain, sauf peut-être à Sokoto.
“Reptiles are Here for Good”
Authors: Haase Birgit 
Published: February 2022

Reptile skins have been sought-after materials for fashionable accessories for the last two centuries at least. This article traces the trend from its historical roots to the present day, with a special focus on the 1920s and 1930s, when “exotic leather” was in particularly high demand for ladies’ shoes, bags, belts etc. Dependent on technical innovations and economic conditions, the development of “reptile fashion” was determined by complex cultural phenomena where orientalism played a significant part. The perception of the material, often connoted as “strange” or “different”, was deeply ambivalent: it oscillated between attraction and rejection, between allure and disgust, between seduction and indignation. Accessories made from the skins of snakes, crocodiles, lizards and other exotic species have been imbued with the ambivalence that surrounded the living animals — an ambivalence shaped by ancient mythology and superstition. On the one hand they are appealing, tempting and attractive, on the other they are repulsive, offensive or even menacing. Aesthetics, ethics and symbolics all combine in shaping our perceptions of these animals and their skins — then just as now. Today’s discussions on the topic seem very much dominated by contemporary ethical considerations centered on the question of cruelty to animals, environmental destruction and ideological as well as economic colonialism. These aspects however were already present in earlier considerations. Despite long standing debates and criticisms the enduring fascination for reptile skins and their associated exoticism, rarity and sensuality still exists today as we can see in contemporary fashion shows.By means of a material culture approach — using images, written sources and extant objects — the article sketches several interdependent layers of perception within the field of aesthetics and ethics. Touching on current issues of sustainability, animal well-being and colonialism, the article highlights subjects such as orientalism, exotism and gender constructions within the realm of fashion history.
Le tragique par le comique
Authors: Grassi Andrea 
Published: February 2022

La comédie, d’une part, et l’Holocauste de l’autre : n’y aurait-il pas là comme une sorte d’affront direct à la mémoire des victimes ? Tabori et Mayorga, l’un par une « farce noire », avec Les cannibales (1968), et l’autre par le Théâtre de l’Absurde, avec Himmelweg (2003), nous montrent néanmoins, eux, une synthèse possible : un art comique sur l’Holocauste peut et doit exister ; mais, pour que celui-ci soit vrai, il faut qu’il parvienne à problématiser le rire au point de le rendre un fait presque étrange : il faut, paradoxalement, qu’il coupe court à tout humour satisfait.

Adsorption Kinetics and Isotherm Models: A Review
Authors: Musah Monday , Azeh Yakubu , Mathew John , Umar Musa , Abdulhamid Zulaihat , Muhammad Aishetu 
Published: February 2022

Adsorption Kinetics describes the rate at which solute is adsorbed and the resident time of the adsorbates on the solid-liquid interface. Adsorption isotherms play important role in determining the interaction between adsorbate and adsorbent and the optimum adsorption capacity of adsorbent. This article considered selected adsorption kinetics and isotherms models. Pseudo first order, Pseudo second order, Elovich, Bhattacharya and Venkobachar, and Natarajan and Khalaf were adsorption kinetics reviewed on the assumption that the process behaves as heterogeneous reaction at solid-liquid interface. Adsorption kinetics equation presented takes the form of straight line, the slopes and intercepts of the plots are used to determine adsorption capacity of adsorbent, rate constant, rate of adsorption and intraparticle diffusion. Value of correlation coefficient obtained is used in determining the adsorption kinetics model that best describe the adsorption process. Langmuir, Freundlich, Radlich-Peterson, Temkin and Dubinin-Radushkevic adsorption isotherms were presented. Their slopes and intercepts provide insight on adsorption affinity, mean free energy, whether the adsorption is physisorption or chemisorptions, single or multilayer. Adsorption kinetics and isotherms reviewed provide essential information required for understanding adsorption process.

Decolonising African Medicines and Health System: Towards Post Covid19 Continental Agenda
Authors: Odeh Godwin , Otitolaiye Catherine 
Published: February 2022

The colonisation of Africa by the imperial powers of Europe has had serious adverse effect on the lives of the people. Over half a century of ceremonial disentangling from colonial clutches, the States of Africa finds it hard to solidly place their feet on global development ground. One of the critical fields Africa has been kowtowing to countries of Asia, Europe and Americas is medicines, which up to the moment, vaccines for treatment of the bulk of the populations are imported. The challenge is not about the incompetent of Africans; neither the ineffectiveness of home-made drugs. But, even if the drug works, the people lacked the psychological confidence in the therapeutic value of it due to colonial and imperial disarticulation and disorientation. It is against this background, the paper makes an interventionist study and argued for the decolonisation of the continent’s medicines and health system in the post Covid19 era. This becomes compelling, because like the World War I and II, the novel pandemic adds yet knowledge to the world, that the whites are not better than the blacks in the knowledge industry. Though not yet uhuru for Africa, the worst ravaged countries by the pandemic are not yet African states, but countries of Asia, Americas and Europe. Against the backdrop of the irrelevance of the white’s superiority myths in the face of the pandemic, the paper charges Africa to look inwardly, in the world system that is fundamentally skewed against her. It finally notes that the continent would be at a crossroads in the wake of global and western conspiracy to depopulate it through the weapons of drugs and vaccines, if it fails to develop and decolonised. It thus, concludes that African governments, policy makers, health experts and scholars should come together in the restless effort to rescue its medicines and health system from the elbow trap of the western society, thereby making Africa truly independent and great in the incoming post Covid19 years.

A survey on the performance and status of disseminated elite N’Dama cattle breeding bulls at the multiplier tier of an Open Nucleus Breeding Scheme in The Gambia for the period 2011 to 2019
Authors: Secka Arss , Camara Lamin , Jeng Momodou , Olaniyan Olawale 
Published: February 2022

The objectives of this survey conducted in 2020 were to profile Multiplier farmers, assess the performance of disseminated N’ breeding bulls at the multiplier cattle herds, and inquire about cattle health and production challenges. Thirty-three farmers living in 33 villages in 5 regions of The Gambia who received 52 elite N’ breeding bulls from the West Africa Livestock Innovation Centre (WALIC) Nucleus tier were interviewed.

The results showed that the disseminated bulls’ performance is generally satisfactorily as asserted by 28 respondents. Twenty-eight respondents reported that the bulls were healthier, 31 ascribed these bulls with stronger libido, 20 asserted that female offspring from these bulls produced more milk, and 26 claimed that offspring had a faster growth rate. A total of 473 calves have been sired by these bulls thus far. However, only 19 bulls are currently present at the multiplier herds due to the exit of 33 bulls arising from various causes. Cattle production challenges reported by farmers included decreasing grazing lands, rampant bush fires, and inadequate watering points; whilst listed health constraints included inadequate access to veterinary drugs and disease prevalence. The multiplication of the disseminated breeding bulls at the Multiplier tier has progressed well in terms of sired offspring, but further transfer to the Commercial Farmer tier is slow. This situation calls for more sensitization of farmers, increased visibility of the breeding programme, and utilization of other reproductive techniques such as artificial insemination to reach more cows for enhanced genetic improvement and productivity.

rare case of simultaneous bilateral testicular torsion in inguinal canal: A case report
Authors: Pal Dilip Kumar , TIWARI ASHUTOSH  KUMAR , Choudhury Sunirmal 
Published: February 2022

Background: Simultaneous bilateral testicular torsion in inguinal canal is a very rare condition which mandates prompt surgical intervention.
Case Report: We report a case of an adolescent male presenting with complaint of severe pain in left inguinal region. Diagnosis of bilateral testicular torsion with bilateral undescended testes was made clinically and supported by Doppler study. This was followed by emergent surgical exploration requiring left orchiectomy and right orchiopexy.
Conclusion: A high index of suspicion is required in any patient presenting with lower abdominal or groin pain and an empty scrotum to clinch the diagnosis and act promptly in an effort to salvage the testes. We believe, irrespective of the time elapsed since the onset of symptoms, surgical intervention should be undertaken as spontaneous torsion and detorsion might be happening, enabling testicular salvage.
