Published: October 2020

Abstract
We present a study of the association between class I methanol masers and cold dust clumps from the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) survey. It was found that almost 100% of class I methanol masers are associated with objects listed in the ATLASGAL compact source catalog. We find a statistically significant difference in the flux density, luminosity, number and column density, and temperature distributions of ATLASGAL sources associated with 95/44 GHz methanol masers compared with those ATLASGAL sources devoid of 95 GHz methanol masers. The masers tend to arise in clumps with higher densities, luminosities, and temperatures compared with both the full sample of ATLASGAL clumps, as well as the sample of ATLASGAL sources that were cross-matched with positions previously searched for methanol masers but with no detections. Comparison between the peak position of ATLASGAL clumps and the interferometric positions of the associated class I and II methanol masers reveals that class I masers are generally located at larger physical distances from the peak submillimeter emission than class II masers. We conclude that the tight association between ATLASGAL sources and class I methanol masers may be used as a link toward understanding the conditions of the pumping of these masers and evolutionary stages at which they appear.
The Milky Way’s Shell Structure Reveals the Time of a Radial Collision

Published: October 2020

Abstract
We identify shell structures in the Milky Way for the first time. We find two shells in the Virgo Overdensity region and two shells in the Hercules Aquila Cloud region using Sloan Digital Sky Survey, Gaia, and LAMOST data. These shell stars are a subset of the substructure previously identified as the Virgo Radial Merger (VRM). Timing arguments for these shells indicate that their progenitor dwarf galaxy passed through the Galactic center 2.7 ± 0.2 Gyr ago. Based on the time of collision, it is also possible that the VRM is related to the phenomenon that created phase-space spirals in the vertical motion of the disk and/or the Splash and could have caused a burst of star formation in the inner disk. We analyze phase mixing in a collection of radial merger N-body simulations and find that shell structure similar to that observed in Milky Way data disappears by 5 Gyr after collision with the Galactic center. The method used to calculate the merger time of the VRM was able to reliably recover the correct merger times for these simulations. Previous work supports the idea that the VRM and the Gaia Sausage/Gaia–Enceladus Merger are the same. However, the Gaia Sausage is widely believed to be 8–11 Gyr old. The disparate ages could be reconciled if the larger age is associated with an infall time when the progenitor crossed the virial radius; we do not constrain the time at which the progenitor became bound to the Milky Way. Alternatively, the Gaia Sausage could be younger than previously thought.

Abstract
The Dark Energy Spectroscopic Instrument (DESI) will execute a nearly magnitude-limited survey of low redshift galaxies (0.05 ≤ z ≤ 0.4, median z ≈ 0.2). Clustering analyses of this Bright Galaxy Survey (BGS) will yield the most precise measurements to date of baryon acoustic oscillations and redshift-space distortions at low redshift. DESI BGS will comprise two target classes: (i) BRIGHT (r < 19.5 mag), and (ii) FAINT (19.5 < r < 20 mag). Here we present a summary of the star-galaxy separation, and different photometric and geometrical masks, used in BGS to reduce the number of spurious targets. The selection results in a total density of ∼800 objects deg−2 for the BRIGHT and ∼600 objects deg−2 for the FAINT selections. A full characterization of the BGS selection can be found in Ruiz-Macias et al.
Emigrer en contexte colonial : La vague de départ des fellahs du Constantinois en 1910
Authors: Hargal Salma 
Published: October 2020

Au cours du printemps 1910, une correspondance du Consul général de France de Beyrouth alerte le Quai d’Orsay du débarquement de centaines de familles de paysans algériens au port de la ville. En même temps, en Algérie, les demandes de passeports pour la Syrie ne cessent d’affluer vers la Préfecture de Constantine et de nombreux départs clandestins sont signalés par les administrateurs coloniaux. Soucieux de limiter ces flux, le Gouvernement général d’Algérie charge les administrateurs des communes concernées de mener des enquêtes. L’étude des rapports établis dans ce cadre, des pétitions d’Algériens musulmans ainsi que d’une série de correspondances administratives ne montre pas seulement que les départs en Grande Syrie sont dus à une série de facteurs de fragilisation économique du fellah constantinois. Il en ressort également que les paysans se sont approprié la procédure de demande de passeport comme moyen de faire entendre leurs doléances au niveau de l’administration coloniale.
The Troubled Image of Africa in Shilia Kaaya’s Poetry
Authors: Mwaifuge Eliah S. 
Published: October 2020

This paper examines representations of Africa in Shilia Kaaya’s poetry. Kaaya’s The Bleeding Heart and other Poems (2009) features thirty-eight poems covering diverse themes. This paper focuses on ten poems which are devoted to colonialism, neo-colonialism and political problems besetting contemporary Africa. It argues that Kaaya’s poetry interrogates the dynamics of colonialism, neo-colonialism and the political problems in Africa and their effect on the development of Africa. It demonstrates how Kaaya’s poems raise salient issues about how Africa’s development — economically and politically, is undermined by both the European coloniser and Africans themselves. The Archetypal approach, which describes images found in a variety of poems written by a single poet, is applied to enhance understanding of the core message (s) of the poems. L’image troublée de l’Afrique dans la poésie de Shilia Kaaya Résumé Cet article examine les représentations de l’Afrique dans la poésie de Shilia Kaaya. Dans The Bleeding Heart and Other Poems (2009), Kaaya présente trente-huit poèmes couvrant divers thèmes. Cet article se focalise sur dix poèmes consacrés au colonialisme, au néo-colonialisme et aux problèmes politiques et développementaux qu’éprouve l’Afrique contemporaine. L’article démontre dans quelle mesure les poèmes de Kaaya soulèvent de questions importantes concernant comment le développement de l’Afrique – sur les plans économique et politique, est miné, d’une part, par le colonisateur européen et d’autre part, par les africains eux-mêmes. L’approche archétypale, une approche qui décrit les images identifiées dans divers poèmes écrits par un seul poète, est utilisée pour renforcer la compréhension du message central des poèmes.
CANCER, POVERTY AND LACK OF ACCESS TO THE BEST THERAPIES IN BRAZIL

Published: October 2020

This year, I followed a young patient who is being investigated for a probable leukemia, He said he was a gardener. I tried to explain what his diagnostic hypothesis was, but I had a distinct feeling that he hadn't quite understood the situation. I always feel this feeling of anguish, a certain impotence, because the exact understanding involves a minimum amount of knowledge that this gentleman must have about health, citizenship or even general education, which a good part of the population that we treat in public hospitals does not have.
This patient who does not understand his illness very well and what effectively needs to be done for a correct diagnosis and treatment. Added to this is the difficulty of having access to new expensive drugs and, as if that were not enough, some essential drugs for the treatment of cancer, such as carmustine, used to conditioning regimen of Bone Marrow transplant, which simply disappeared from the Brazilian market and left with restrict options to treat these patients.
In any case, it is not the first time that we have dealt with this reality, and many will say that there is nothing new in my report or that it used to be much worse. I agree with these two statements, but this process remains very difficult, painful and very worrying. I participated in february of a congress in the United States; there I could see the main updates in the treatments of onco-hematology and bone marrow transplantation. I presented an article and, throughout the debate, I tried to show my professional colleagues the profound differences, not to say abysmal, between our realities in Latin America and first world countries. This distance becomes increasingly larger as treatment progresses based on targeted and cellular therapies, with drugs such as immunotherapy associated with chemotherapy or the use of "smart" cells that destroy cancer, which are difficult to access.
Thus, we come to the difficult trinomial that consists of cancer, poverty and lack of access. This leads us to a deep reflection on the real paths we are taking and where this modern, technological and fast society will take us all, if we do not pay attention to the need to place the individual as the priority center of all our actions.

<p>In response to the need for more research evidence, as an empirical base for discussion on the experiences of young people, the current study aims to contribute to the discussion on their attitudes and behaviors in times of pandemic crisis. It is of great importance, that under the pressure of social limits on social distancing for the novel Coronavirus (COVID-19), young students have to adapt more efficiently with new technologies both every day and for educational practices, where their experiences involve multiple, complex and overlapping social and digital universes. According to the findings of this study, it is clear that as long as universities were closed, most of the/our young students did not have any difficulty in switching to online teaching. In addition, the participants' responses show that as Gen Z’s, they want to have the ability to learn new skills and make new experiences.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0684/a.php" alt="Hit counter" /></p>

La jubilación desde la percepción de los profesores activos laboralmente
Authors: Mejía Velasco Lidia Elizabeth 
Published: October 2020

Desde que la sociedad se basó en la productividad material para valorar al ser humano, las personas que se jubilan están propensas a la desvalorización, el olvido y la exclusión, no solo por parte de la sociedad, sino incluso por parte de la propia familia. El objetivo del artículo es dar a conocer la percepción que tienen los profesores activos de la FAHUSAC sobre la jubilación, acción considerada valiosa en tanto permite sistematizar las experiencias internas de quienes están cercanos al proceso de jubilación. A través de una entrevista y un microrrelato de vida dirigida a diez profesores activos laboralmente; se logró evidenciar que la aceptación de la jubilación por parte de los profesores es muy alta, reflejada en emociones y pensamientos positivos. Sin embargo, existen prejuicios e información en el ambiente social que no son favorables, estos prejuicios consideran que la jubilación es una etapa improductiva y la persona jubilada es considerada obsoleta, una carga familiar, carente de vida y de salud, en este sentido la etapa de la jubilación puede ser indeseada, lo que tiene vinculación directa o indirecta con algunas emociones de tristeza, temor, incertidumbre e indiferencia. Esto indica que la familia, las autoridades y la sociedad tienen la tarea pendiente de fortalecer valores y desarrollar acciones para mejorar la percepción que se tiene sobre la jubilación.

Abstract
Objective: To analyze the outcome of Video assisted Thoracoscopy (Vats) in Primary Spontaneous Pneumothorax (PSP).
Methods: This case series was carried out from Jan 2010 to Jan 2017 in Dept of Thoracic Surgery CMH Rawalpindi and Lahore. A total of 98 patients underwent Video-assisted thoracoscopic for PSP. Inclusion criteria were physiologically fit patients with PSP for recurrent attacks, occupational hazards and prolonged air leak. Exclusion criteria included secondary spontaneous pneumothorax, previous pleurodesis and physiologically unfit patient for general anesthesia. Vanderschueren's thoracoscopic classification was used for macroscopic staging. A 3-port technique was used for apical stapling with partial pleurectomy up to 6th rib. Parietal pleura and diaphragm was also abraded.
Results: Occupational hazard was the commonest indication for surgery, n= 39 (39.7%). This was followed by recurrent pneumothorax n=37 (37.7%), persistent air leak n= 19 (19.38%), and contra lateral pneumothorax n=4 (4.08). Mean age was 22.8 years ± 6.5. Majority of the cases were in stage 3 of Vanderschueren’s classification, n=69 (70.4%). Stage 4 were n= 18 and stage 2 were n=7. Mean operative time was 51minutes ±14.4. Postoperative prolonged air leak occurred in 3 patients and post-operative neuralgia occurred in 8 patients. Mean follow-up was 22 months ± 5.5, range 5-24 months for all patients. One had generalized recurrence and 2 patients have subpulmonic trapping of air.
Conclusions: Video-assisted thoracoscopic stapling and pleurectomy is an effective definitive treatment for primary spontaneous pneumothorax when indicated with minimal recurrence.
Keywords: Video-assisted thoracoscopy, blebs, pneumothorax.

Abstract. Interactions between water and nanoparticles are relevant for
atmospheric multiphase processes, physical chemistry, and materials science. Current knowledge of the hygroscopic and related physicochemical properties of nanoparticles, however, is restricted by the limitations of the available measurement techniques. Here, we present the design and performance of a nano-hygroscopicity tandem differential mobility analyzer (nano-HTDMA) apparatus that enables high accuracy and precision in hygroscopic growth measurements of aerosol nanoparticles with diameters less than 10 nm. Detailed methods of calibration and validation are provided. Besides maintaining accurate and stable sheath and aerosol flow rates (±1 %),
high accuracy of the differential mobility analyzer (DMA) voltage (±0.1 %) in the range of
∼0–50 V is crucial for achieving accurate sizing and small sizing offsets between the two DMAs (<1.4 %). To maintain a
stable relative humidity (RH), the humidification system and the second DMA
are placed in a well-insulated and air conditioner housing (±0.1 K).
We also tested and discussed different ways of preventing predeliquescence
in the second DMA. Our measurement results for ammonium sulfate
nanoparticles are in good agreement with Biskos et al. (2006b), with no
significant size effect on the deliquescence and efflorescence relative
humidity (DRH and ERH, respectively) at diameters down to 6 nm. For sodium sulfate nanoparticles, however, we find a pronounced size dependence of DRH and ERH between 20 and 6 nm nanoparticles.
Imprints of evaporative conditions and vegetation type in diurnal temperature variations
Authors: Panwar Annu , Renner Maik , Kleidon Axel 
Published: October 2020

Abstract. Diurnal temperature variations are strongly shaped by the absorption of solar radiation, but evaporation, or the latent heat flux, also plays an important role. Generally, evaporation cools. Its relation to diurnal temperature variations, however, is unclear. This study investigates the diurnal response of surface and air temperatures to evaporative conditions for different vegetation types. We use the warming rate, defined as the increase in temperature in response to absorbed solar radiation in the morning, and evaluate how it changes with evaporative fraction, which is an indicator of the evaporative conditions. Results for 51 FLUXNET sites show that the warming rate of air temperature carries very weak imprints of evaporative fraction across all vegetation types. However, the warming rate
of surface temperature is highly sensitive to evaporative fraction with a
value of ∼23×10-3 K (W m-2)-1, indicating stronger evaporative cooling for moister conditions. Contrarily, the warming rates of surface and air temperatures are similar at forest sites and carry literally no imprints of evaporative fraction. We explain these contrasting patterns with an analytical surface energy balance model. The derived expressions reproduce the observed warming rates and their sensitivity to evaporative fraction in all vegetation types. Multiplying the warming rate with daily maximum solar radiation gives an approximation for the diurnal surface temperature range (DTsR). We use our model to compare the individual contributions of solar radiation, evaporative conditions, and vegetation (by its aerodynamic conductance) in shaping DTsR and show that the high aerodynamic conductance of forests reduces DTsR substantially more (−56 %) than evaporative cooling (−22 %). We further show that the strong diurnal variation in aerodynamic conductance (∼2.5 times of the mean across vegetation types) reduces DTsR by ∼35 % in short vegetation and savanna but only by ∼22 % in forests. We conclude that diurnal
temperature variations may be useful for predicting evaporation for short
vegetation. In forests, however, the diurnal variations in temperatures are
mainly governed by their high aerodynamic conductance, resulting in negligible imprints of evaporative conditions.

El presente artículo tiene como objetivo describir y valorar la utilidad de los procesos creativos y las prácticas artísticas como herramientas mediadoras en la promoción de la salud comunitaria. Para ello, se narran cinco experiencias concretas que tienen lugar dentro del marco de colaboración del Organismo Autónomo de Madrid Salud, del Ayuntamiento de Madrid y la Facultad de Bellas Artes de la Universidad Complutense de Madrid. Esta colaboración se materializa en el proyecto Arte y Salud con el propósito de desarrollar procesos de investigación basada en las artes en los Centros Municipales de Salud Comunitaria (CMSc). De esta manera, el arte y los artistas se configuran como agentes activos en la salud comunitaria, proporcionando herramientas y metodologías. A partir de estas experiencias, han surgido una serie de reflexiones interesantes en relación a las aportaciones de diferentes metodologías en este ámbito, a las cuestiones que tienen en común las diferentes experiencias desarrolladas a pesar de que tienen lugar en diferentes contextos, al papel del arte como mediador en la promoción de la salud y al rol del profesional del arte en el trabajo en la salud comunitaria para lograr sus objetivos de promoción de la salud integral. En definitiva, este texto se transforma en una apuesta por la consolidación del profesional de arte en contextos de salud comunitaria.

Arkitekttegninger og byggesten til "Die Christensens" ordkatedraler – om Inger Christensens arkiv
Authors: Kromann Thomas Hvid 
Published: October 2020

Inger Christensens arkiv i Det Kongelige Bibliotek kaster nyt lys på den proces, der er gået forud for værkerne i form af manuskripter, udkast m.m., og arkivet giver et nuanceret blik på forfatterinden som figur i det litterære felt.
Arkivets første og største del blev erhvervet tilbage i 2007. Da Det Kongelige Bibliotek ved samme lejlighed blev lovet supplerende materiale, ventede man fornuftigvis med ordningen og katalogiseringen af de fem flyttekasser med usorteret materiale, indtil det resterende var blevet afleveret. Inger Christensens død i 2009 udskød ordningen på ubestemt tid, og først i sommeren 2015 modtog Håndskriftsamlingen de resterende papirer, hvorefter ordningen kunne gå i gang med henblik på at tilgængeliggøre et materiale, der fylder 60 arkivæsker i alt, indeholdende breve, manuskripter og andre typer dokumenter.
