Published: February 2021

Kehidupan tidak terlepas dari hubungan antara manusia dengan Tuhan-Nya, salah satunya cara yaitu shalat sebagai rukun islam yang ke-2. Shalat merupakan satu hal yang wajib dilakukan bagi setiap umat Islam mulai dari baligh dan berakal. Dikarenakan pengaruh asing yang sangat masuk kedalam pemikiran budaya anak-anak, maka materi tentang shalat sangat disarankan dalam era globalisasi. Masalah yang ada saat ini, media yang digunakan masih bersifat konvensional. Siswa hanya bisa mendengarkan penjelasan dari guru saja. Hal tersebut terkadang membuat siswa merasa bosan dan malas untuk belajar karena tidak ada interaksi yang memberikan peran aktif kepada siswanya. Media pembelajaran ini menggunakan buku pembelajaran bergambar (yang dijadikan penanda untuk disimpan oleh smartphone, menjadi animasi 3 dimensi, 3D).

Constraining Primordial Black Holes with Dwarf Galaxy Heating
Authors: Lu Philip , Takhistov Volodymyr , Gelmini Graciela B. , Hayashi Kohei , Inoue Yoshiyuki , Kusenko Alexander 
Published: February 2021

Abstract
Black holes formed in the early universe, prior to the formation of stars, can exist as dark matter and also contribute to the black hole merger events observed in gravitational waves. We set a new limit on the abundance of primordial black holes (PBHs) by considering interactions of PBHs with the interstellar medium, which result in the heating of gas. We examine generic heating mechanisms, including emission from the accretion disk, dynamical friction, and disk outflows. Using the data from the Leo T dwarf galaxy, we set a new cosmology-independent limit on the abundance of PBHs in the mass range

, relevant for the recently detected gravitational-wave signals from intermediate-mass BHs.

Abstract
We present an analysis of the R ≲ 1.5 kpc core regions of seven simulated Milky Way-mass galaxies, from the FIRE-2 (Feedback in Realistic Environments) cosmological zoom-in simulation suite, for a finely sampled period (Δt = 2.2 Myr) of 22 Myr at z ≈ 0, and compare them with star formation rate (SFR) and gas surface density observations of the Milky Way’s Central Molecular Zone (CMZ). Despite not being tuned to reproduce the detailed structure of the CMZ, we find that four of these galaxies are consistent with CMZ observations at some point during this 22 Myr period. The galaxies presented here are not homogeneous in their central structures, roughly dividing into two morphological classes; (a) several of the galaxies have very asymmetric gas and SFR distributions, with intense (compact) starbursts occurring over a period of roughly 10 Myr, and structures on highly eccentric orbits through the CMZ, whereas (b) others have smoother gas and SFR distributions, with only slowly varying SFRs over the period analyzed. In class (a) centers, the orbital motion of gas and star-forming complexes across small apertures (R ≲ 150 pc, analogously ∣l∣ < 1° in the CMZ observations) contributes as much to tracers of star formation/dense gas appearing in those apertures, as the internal evolution of those structures does. These asymmetric/bursty galactic centers can simultaneously match CMZ gas and SFR observations, demonstrating that time-varying star formation can explain the CMZ’s low star formation efficiency.

Abstract
Gas-rich circumstellar disks are the cradles of planet formation. As such, their evolution will strongly influence the resulting planet population. In the ESO DESTINYS large program, we study these disks within the first 10 Myr of their development with near-infrared scattered-light imaging. Here we present VLT/SPHERE polarimetric observations of the nearby class II system SU Aur in which we resolve the disk down to scales of ∼7 au. In addition to the new SPHERE observations, we utilize VLT/NACO, HST/STIS, and ALMA archival data. The new SPHERE data show the disk around SU Aur and extended dust structures in unprecedented detail. We resolve several dust tails connected to the Keplerian disk. By comparison with ALMA data, we show that these dust tails represent material falling onto the disk. The disk itself shows an intricate spiral structure and a shadow lane, cast by an inner, misaligned disk component. Our observations suggest that SU Aur is undergoing late infall of material, which can explain the observed disk structures. SU Aur is the clearest observational example of this mechanism at work and demonstrates that late accretion events can still occur in the class II phase, thereby significantly affecting the evolution of circumstellar disks. Constraining the frequency of such events with additional observations will help determine whether this process is responsible for the spin–orbit misalignment in evolved exoplanet systems.

Published: February 2021

Twenty-two native Crop Wild Relatives (CWR) occur in specific dry environments of Madeira Archipelago, like Desembarcadouro islet in Ponta de São Lourenço and Chão islet in Desertas Islands. Nine of them share the same gene pool with crop species included in Annex I of the International Treaty on Plant Genetic Resources for Food and Agriculture. Amongst them, Beta patula Aiton, an IUCN Critically Endangered species, has been studied in detail for in situ and ex situ conservation. The present paper summarises the information recorded during the Beta patula population assessment. Valuable information on plant communities associated with this species was obtained.
The data provides information of a vegetation census spanning 7 years, from 2014 to 2020, in two uninhabited islets where Beta patula occurs, Desembarcadouro and Chão islets. The collected dataset consists of 1,786 vegetation descriptions, where 31 species were recorded. All generated data have been published and will be used towards the implementation of conservation actions and to establish a middle term management protocol for Beta patula and other CWR in situ conservation in the framework of a genetic reserve. This work is part of a EU LIFE Project, LIFE RECOVER NATURA and was conducted by members of the ISOPlexis Center, University of Madeira.
Le logiciel d’aide à l’analyse Monika et l’analyse ‘par position’ dans l’univers pentatonique
Authors: De Lavenère Véronique 
Published: February 2021

Cet article procède à l’analyse d’un ensemble de musiques de danse pour orgue à bouche issu d’une petite population tibéto-birmane établie au Laos (Asie du Sud Est). Bien loin de se réduire à des particularités motiviques, l’organisation interne de ces pièces repose sur des règles implicites mais contraignantes qui relèvent d’un véritable système : le pentatonisme. L’article questionnera l’apport du logiciel d’aide à l’analyse Monika – en particulier l’analyse des durées cumulées des hauteurs – pour l’identification de ces règles sous-jacentes. Il cernera aussi le rôle du logiciel dans un cheminement analytique qui conduit à reconnaître la nécessité d’une analyse ‘par position’.
La révolte insubordonnée
Authors: Silva Breno , Menezes Cícero 
Published: February 2021

À partir de l’image emblématique du cocktail Molotov lancé contre quelque chose, une réflexion est recherchée sur l’instant de la révolte et ses développements fulgurants. La révolte vue dans une dimension phénoménique, indissociable de l’expérience du révolté, suspend le temps historique et se configure comme un acte autonome, indépendant de quoi que ce soit. Dans de telles conditions, on peut la considérer en tant qu’acte insubordonné, qui ne se soumet à rien. Il s’agit, dans une conception batallienne, d’un acte souverain. Mais quelles seraient les contributions de penser la révolte à l’instant de sa réalisation insubordonnée ? Dans cet engagement se dégage peut-être une pensée fulgurante de la révolte, transfigurant l’ennemi, les motivations personnelles, la cause collective et même le soi, joint à l’émergence d’une autre collectivité. Dans une telle émergence, l’instant de la révolte réalise, dans le refus et la contestation d’un mode de vie servile, une sorte de souveraineté solidaire, dans laquelle la révolte n’en est pas moins au nom de tous les siens .
An analysis of the relationship between media communication and social protest in China
Authors: Bin Wang 
Published: February 2021

Les protestations sociales en Chine se sont déroulées dans un contexte réaliste et historique spécifique et ont eu une relation compliquée avec les médias ancrés dans la structure sociale spécifique. Notre intention est d’illustrer trois facteurs qui influencent le rôle des médias dans les manifestations sociales en Chine : le système médiatique, les règles de fonctionnement des institutions médiatiques et des professionnels des médias, et le capital social des manifestants et les stratégies de protestation. En se basant sur les points de vue et le degré d’implication des médias dans les protestations, cet article souligne les rôles des médias traditionnels dans les protestations sociales en quatre catégories : « défenseur », « promoteur », « coordinateur » et « obstructeur ». Ensuite, cet article propose trois types d’interaction discursive entre les médias traditionnels et les médias en ligne : les médias traditionnels dominent l’opinion publique ; les médias traditionnels et les médias en ligne dominent conjointement l’opinion publique ; les médias en ligne dominent l’opinion publique.

Abstract
The IL-21/IL-21R interaction plays an important role in a variety of immune diseases; however, the roles and mechanisms in intracellular bacterial infection are not fully understood. In this study, we explored the effect of IL-21/IL-21R on chlamydial respiratory tract infection using a chlamydial respiratory infection model. The results showed that the mRNA expression of IL-21 and IL-21R was increased in Chlamydia muridarum–infected mice, which suggested that IL-21 and IL-21R were involved in host defense against C. muridarum lung infection. IL-21R−/− mice exhibited less body weight loss, a lower bacterial burden, and milder pathological changes in the lungs than wild-type (WT) mice during C. muridarum lung infection. The absolute number and activity of CD4+ T cells and the strength of Th1/Th17 responses in IL-21R−/− mice were significantly higher than those in WT mice after C. muridarum lung infection, but the Th2 response was weaker. Consistently, IL-21R−/− mice showed higher mRNA expression of Th1 transcription factors (T-bet/STAT4), IL-12p40, a Th17 transcription factor (STAT3), and IL-23. The mRNA expression of Th2 transcription factors (GATA3/STAT6), IL-4, IL-10, and TGF-β in IL-21R−/− mice was significantly lower than that in WT mice. Furthermore, the administration of recombinant mouse IL-21 aggravated chlamydial lung infection in C57BL/6 mice and reduced Th1 and Th17 responses following C. muridarum lung infection. These findings demonstrate that IL-21/IL-21R may aggravate chlamydial lung infection by inhibiting Th1 and Th17 responses.

Published: February 2021

Background:
Idiopathic guttate hypomelanosis (IGH) is a common, acquired dermatosis characterized by multiple, round or oval, hypopigmented to depigmented macules. A variety of therapies with variable success are described, despite that, the treatment remains still unsatisfactory and a therapeutic challenge for the treating specialist.

Objective:
The objective of this study is to compare the safety and efficacy of 88% phenol application and cryotherapy in repigmentation of IGH macules.

Materials and Methods:
A total of 30 patients with more than 10 IGH macules were selected. For each enrolled patient, 88% phenol was applied to 5 IGH macules and single cryotherapy for 3–5 s was applied for another 5 IGH macules once in a month till the repigmentation for maximum of 3 applications. Patients were assessed monthly for 3 months for the side effects and improvement in pigmentation. The degree of improvement in pigmentation was assessed using a grading system, <25% - no response (Grade-1), 26%–50% - minimal (Grade-2), 51%–75% - good (Grade-3), and >75% - excellent response (Grade-4).

Results:
A total of 25 patients completed the study. At the end of the treatment period, out of 125 macules treated with short contact cryotherapy 75 (60%) macules showed excellent response and 20 (16%) macules showed good response. In phenol group, out of 125 macules 37 (29.6%) and 29 (23.2%) macules showed excellent and good improvement in pigmentation respectively, with P < 0.05. Side effects such as persistent scabbing, ulceration were more common with 88% phenol application compared to cryotherapy.

Conclusion:
Short contact cryotherapy of 3–5 s was found to be more efficacious and safe compared to therapeutic wounding with 88% phenol in inducing pigmentation of IGH macules.

Authors: Bhatia Amrit Singh , Badad Ambresh , Hogade Ashok S , Spoorthy M 
Published: February 2021

Background:
Leprosy is a chronic granulomatous infection with varied clinical presentations. Dermatoscopy is a noninvasive technique that allows rapid and magnified in vivo observation of the skin with the visualization of morphologic features that are invisible to the naked eye. In our study, we aim to describe the dermatoscopic features of all types of leprosy and correlate with clinical and histopathological findings.

Materials and Methods:
A prospective observational study was done on all the leprosy patients attending OPD over a period of 1 year. The study patients were categorized as per Ridley–Jopling classification. The lesions of different types of leprosy were photographed and evaluated by dermatoscopy and biopsied.

Results:
A total of 60 patients (34 males and 26 females) were taken under the study. Of 60 patients, 6 cases of tuberculoid leprosy, 22 cases of borderline tuberculoid (3 with Type 1 reaction), 16 cases of borderline lepromatous, 12 cases of lepromatous leprosy (5 with Type 2 reaction), and 4 cases of Histoid leprosy. The dermatoscopic features seen are yellowish-orange areas and vascular structures such as linear branching vessels and crown vessels. Broken pigment network and white chrysalis like areas are also seen. Absence or diminished hair follicles and eccrine duct openings are seen in tuberculoid spectrum. Scaling and follicular plugs are seen in type 1 reaction.

Conclusion:
Yellowish-orange areas and vascular structures are the common dermatoscopic features seen in leprosy. Broken pigment network and paucity of appendageal structures are other features seen.

Published: February 2021

Background. Immune disorders in antitumor treatment of obese patients may depend on the severity of the inflammatory process, which justifies the need to take into account the intensity of the latter in the analysis of complications of antitumor treatment in obese individuals. Purpose – evaluation of immune disorders after radiation therapy in obese patients with different intensity of the inflammatory process. Materials and methods. 65 patients with stage I–II endometrial cancer underwent pangysterectomy and a postoperative course of remote gamma therapy. Examinations were performed before treatment and after radiation therapy. Subpopulation composition of lymphocytes, phagocytic activity of neutrophils, levels of circulating immune complexes and immunoglobulins G, A, M were determined by standard methods. The SF-3000 «SYSMEX» analyzer was used to evaluate hematological parameters. The level of C-reactive protein (CRP) was determined using an analyzer «RESPONS 910». Insulin and leptin levels were assessed by enzyme-linked immunosorbent assay. Results and discussion. Immune and hematological parameters were evaluated in 3 groups of patients. Group I included patients with normal body weight (BMI < 25), II and III groups consisted of obese patients (BMI > 30). Group II included patients with a CRP level below the median, which was 18,0 mg/l, group III – patients with a CRP level above 18.0 mg/l. In patients of group II there was a higher absolute and relative number of lymphocytes, the absolute number of CD3+-, CD4+- and CD8+-lymphocytes compared with those registered in groups I and III. After radiation therapy, the absolute number of lymphocytes and lymphocyte subpopulations decreased in all groups. As before treatment, higher levels of these indicators were registered in group II. In obese patients, the relative number of NK cells was lower than that determined in patients of group I before and after treatment. Conclusions. Patients with obesity and low intensity of the inflammatory process have less pronounced immune disorders after radiation therapy compared with patients who had a normal body weight and individuals with obesity and high levels of CRP.
