Generating Transverse Loop Oscillations through a Steady-flow Driver
Authors: Karampelas Konstantinos , Van Doorsselaere Tom
Published: July 2020

In recent years, the decay-less regime of standing transverse oscillations in coronal loops has been the topic of many observational and numerical studies, focusing on their physical characteristics, as well as their importance for coronal seismology and wave heating. However, no definitive answer has yet been given on the driving mechanism behind these oscillations, with most studies focusing on the use of periodic footpoint drivers as a means to excite them. In this paper, our goal is to explore the concept of these standing waves being self-sustained oscillations, driven by a constant background flow. To that end, we use the PLUTO code, to perform 3D magnetohydrodynamic simulations of a gravitationally stratified straight flux tube in a coronal environment, in the presence of a weak flow around the loop, perpendicular to its axis. Once this flow is firmly set up, a transverse oscillation is initiated, dominated by the fundamental kink mode of a standing wave, while the existence of a second harmonic is revealed, with a frequency ratio to the fundamental mode near the observed ones in decay-less oscillations. The presence of vortex shedding is also established in our simulations, which is connected to the “slippery” interaction between the oscillator and its surrounding plasma. We thus present a proof-of-concept of a self-oscillation in a coronal loop, and we propose it as a mechanism that could interpret the observed decay-less transverse oscillations of coronal loops.
Hadronic versus Leptonic Models for γ-Ray Emission from VER J2227+608
Authors: Liu Siming , Zeng Houdun , Xin Yuliang , Zhu Hui
Published: July 2020

Recent observations of VER J2227+608 reveal a broken power γ-ray spectrum with the spectral index increasing from ∼1.8 in the GeV energy range to ∼2.3 in the TeV range. Such a spectral break can be attributed to radiative energy loss of energetic electrons in the leptonic scenario for the γ-ray emission, which, in combination with the characteristic age of the nearby pulsar, can be used to constrain the magnetic field in the emission region. We show that the radio and X-ray observations can also be explained in such a scenario. In the hadronic scenario, the spectral break can be attributed to diffusion of energetic ions in a turbulent medium and detailed spectral measurement can be used to constrain the diffusion coefficient. These two models, however, predict drastically different spectra above 100 TeV, which will be uncovered with future high-resolution observations, such as Large High Altitude Air Shower Observatory (LHAASO) and/or Cherenkov Telescope Array (CTA).
The Ionized Warped Disk and Disk Wind of the Massive Protostar Monoceros R2-IRS2 Seen with ALMA

Published: July 2020

Theories of massive star formation predict that massive protostars accrete gas through circumstellar disks. Although several cases have been found already thanks to high angular-resolution interferometry, the internal physical structure of these disks remains unknown, in particular whether they present warps or internal holes, as observed in low-mass protoplanetary disks. Here, we report very high angular-resolution observations of the H21α radio recombination line carried out in Band 9 with the Atacama Large Millimeter/submillimeter Array (beam of 80 mas × 60 mas, or 70 au × 50 au) toward the IRS2 massive young stellar object in the Monoceros R2 star-forming cluster. The H21α line shows maser amplification, which allows us to study the kinematics and physical structure of the ionized gas around the massive protostar down to spatial scales of ∼1–2 au. Our ALMA images and 3D radiative transfer modeling reveal that the ionized gas around IRS2 is distributed in a Keplerian circumstellar disk and an expanding wind. The H21α emission centroids at velocities between −10 and 20 km s−1 deviate from the disk plane, suggesting a warping for the disk. This could be explained by the presence of a secondary object (a stellar companion or a massive planet) within the system. The ionized wind seems to be launched from the disk surface at distances ∼11 au from the central star, consistent with magnetically-regulated disk wind models. This suggests a similar wind-launching mechanism to that recently found for evolved massive stars such as MWC349A and MWC922.

Prior to this study, few collections and records were made of the land snails in Cambodia and the historical taxa had never been reviewed. Herein a report on the land snail diversity based on specimens collected recently from karstic and non-karstic areas in southern Cambodia is provided. This checklist presents 36 species of land snails (two Neritimorpha, six Caenogastropoda, and 28 Heterobranchia). Illustrations and brief taxonomic notes/remarks are provided for every species. We also describedGeorrisa carinataSutcharit & Jirapatrasilp,sp. nov.based on some distinct shell morphological characters. Since the first descriptions during the colonial period in the nineteenth century, some land snail species (e.g.,Trichochloritis norodomiana,Durgella russeola,Anceyoconcha siamensis obesulacomb. nov.,Anceyoconcha chaudoensiscomb. nov., andSuccinea tenuis) have not been reported subsequently. This probably reflects a lack of knowledge concerning land snail biodiversity in this country. To our knowledge, this is the first comprehensive survey of land snails in southern Cambodia. A need for more field research and systematic revision of the land snails in this interesting region is also highlighted and demonstrated.

Published: July 2020

Le site du Kemmelberg/mont Kemmel a été fouillé dans les années 60-70 du siècle dernier. Les résultats ont montré que les habitants de ce site de hauteur faisaient partie du réseau élitaire européen du v e s. av. J.-C. Parmi la culture matérielle attestée, la céramique fut l’objet de plusieurs études, avec une attention particulière portée à la céramique peinte rouge. Dans cette contribution, les objets métalliques du mont Kemmel sont documentés et étudiés pour la première fois. Les dix-sept artéfacts ont été découverts dans trois secteurs. L’utilisation de nouvelles technologies apporte de nouvelles idées sur la connaissance métallurgique et les modes de production de l’Âge du Fer. Ces artefacts montrent que l’élite du Kemmelberg avait des contacts avec le monde rhénan et méditerranéen au début du second Âge du Fer.
Disease Risk–Associated Genetic Variants in STAT1 and STAT4 Function in a Complementary Manner to Increase Pattern-Recognition Receptor–Induced Outcomes in Human Macrophages
Authors: Hedl Matija , Sun Rui , Abraham Clara
Published: July 2020

STAT proteins can regulate both pro- and anti-inflammatory cytokine signaling. Therefore, identifying consequences of modulating expression of a given STAT is ultimately critical for determining its potential as a therapeutic target and for defining the mechanisms through which immune-mediated disease variants in STAT genes contribute to disease pathogenesis. Genetic variants in the STAT1/STAT4 region are associated with multiple immune-mediated diseases, including inflammatory bowel disease (IBD). These diseases are characterized by dysregulated cytokine secretion in response to pattern-recognition receptor (PRR) stimulation. We found that the common IBD-associated rs1517352 C risk allele increased both STAT1 and STAT4 expression in human monocyte-derived macrophages (MDMs). We therefore hypothesized that the STAT1/STAT4 variant might regulate PRR-initiated responses in a complementary and cooperative manner because of the important role of autocrine/paracrine cytokines in modulating PRR-initiated signaling. STAT1 and STAT4 were required for PRR- and live bacterial-induced secretion of multiple cytokines. These outcomes were particularly dependent on PRR-initiated autocrine/paracrine IL-12–induced STAT4 activation to generate IFN-γ, with autocrine IFN-γ then signaling through STAT1. STAT1 and STAT4 also promoted bacterial-induced cytokines in intestinal myeloid cells and PRR-enhanced antimicrobial pathways in MDMs. Importantly, MDMs from rs1517352 C IBD risk allele carriers demonstrated increased TLR4-, IFN-γ– and IL-12–induced STAT1 and STAT4 phosphorylation and cytokine secretion and increased TLR4-enhanced antimicrobial pathways. Taken together, STAT1 and STAT4 expression is coregulated by a shared genetic region, and STAT1/STAT4-immune disease–associated variants modulate IFN-γ– and IL-12–associated outcomes, and in turn, PRR-induced outcomes, highlighting that these genes cooperate to regulate pathways relevant to disease pathogenesis.
Exotic t-structures and actions of quantum affine algebras
Authors: Cautis Sabin , Koppensteiner Clemens
Published: July 2020

We explain how quantum affine algebra actions can be used to systematically construct "exotic" t-structures. The main idea, roughly speaking, is to take advantage of the two different descriptions of quantum affine algebras, the Drinfeld–Jimbo and the Kac–Moody realizations.

Our main application is to obtain exotic t-structures on certain convolution varieties defined using the Beilinson–Drinfeld and affine Grassmannians. These varieties play an important role in the geometric Langlands program, knot homology constructions, K-theoretic geometric Satake and the coherent Satake category. As a special case we also recover the exotic t-structures of Bezrukavnikov–Mirković [BM] on the (Grothendieck–)Springer resolution in type A.

Effect of Graded Oil Palm Kernel Shells on Compaction of Weak o Problematic Sub-Grade Soils
Authors: Affam M. , Wilson R. Ewusi , Asenso-Gjambibi D.
Published: July 2020

AbstractSub-grade is the ultimate load bearer of vehicular traffic load in a pavement structure. A weak sub-grade or problematic soils require some improvements like soil stabilisation, soil reinforcement and/or capping of the sub-grade layer. These sub-grade improvement methods increase the total project cost because non-local materials such as cement, geosynthetics and hydrated lime are commonly used. The use of graded oil palm kernel shells (OPKS) which are local, cheaper and readily available as a soil improvement material was assessed in this research. This assessment was done by mixing sub-grade material with 2.8 mm, 5 mm and 10 mm graded OPKS. 10 %, 20 % and 30 % of each graded OPKS was added separately to the soil to form nine composite materials. These composite materials including the natural soil were tested for their California Bearing Ratio (CBR) values. The investigation proved that the composite made of 20 % 2.8 mm graded OPKS yielded a soaked CBR of 23.5 % which is a 197.47 % increase in soaked CBR compared to that of the natural soil. The soaked CBR samples of the graded OPKS composite materials absorbed lesser amounts of water in comparison to that of the natural soil. This behaviour implies that some capillary force created at un-soaked condition in the composite materials was preserved; therefore, the composite materials generally have higher CBR values than the natural soil. Keywords: Oil Palm Kernel Shells (OPKS), Problematic Soils, Lightweight Aggregate (LWA)
The Trajectory of Lost Mercury in Artisanal and Small Scale Gold Extraction in Ghana
Authors: Al-Hassan S , Yaganuma L. , Odoi B.
Published: July 2020

AbstractThe Artisanal and Small Scale Mining (ASSM) industry is of great importance to the Ghanaian economy. It provides employment for the teeming youth directly and indirectly and produces gold for the local goldsmiths, among other benefits. Concomitant to their operations, ASSM causes significant environmental pollution with chemicals, predominantly mercury. Mercury is used by small scale miners in the processing of ore mined because it is relatively easy to use and readily available. The laws regulating small scale gold mining in Ghana do not forbid the use of mercury even though there is a loud outcry against the use of mercury in small scale gold mining. The operations have resulted in the discharge of mercury into the environment indiscriminately. No attempt is made by the miners to recover lost mercury hence all of it is lost to the environment. This paper presents the findings of a study that investigated the trajectory of the mercury lost into the environment. The results showed that 2 g of mercury was lost to the environment for every gram of gold recovered through ASSM; 39% of it was lost to the atmosphere due to roasting of the amalgam whilst the remaining 61% was lost into water and spillage onto the ground. Keywords: Mercury, Atmosphere, Pollution, Environment, Socio-economic

Published: July 2020

Abstract

Some countries still face daunting challenges of managing ever-increasing waste generated, especially plastic and waste vehicle tyres.  Whilst some developed countries have adopted innovative ways such as catalytic or pyrolytic decomposition processes for energy or fuel generation from these wastes, developing countries like Ghana still dispose off indiscriminately around communities or un-engineered dumpsites. Hence, this study sought to transform waste vehicle tyres into fuel which invariably minimises or eliminates its environmental impact. Particularly, waste vehicle tyres (sourced from dumpsites in Tarkwa, Ghana) were washed, shredded and decomposed via pyrolysis at high temperature range (~ 450 - 650 oC) using locally designed and fabricated reactor. The physicochemical properties (such as water content, flashpoint, density, sulphur content, solids and viscosity) of the pyrolysis oil produced were also examined using the American Society for Testing and Materials (ASTM) standards and procedures. The results showed that the viscosity, flashpoint and the density of the pyrolysis oil produced were 0.904 cSt, 34.5 oC, and 850.6 kg/m3 (at 15 oC), respectively. The sulphur, water and solids/particulates contents were 4340.0 ppm, 0.8 vol.%, and 483,495.5 ppm, respectively. It was also observed that the pyrolysis oil obtained appeared as thick, single-phase liquid with dark colour and strong odour at room temperature. Relatively, the properties of pyrolysis oil produced without further treatment did not meet the International specification for diesel fuel, hence its usage would require further treatments such as desulphurisation, decanting, centrifugation and filtration. Overall, the study has demonstrated that the pyrolysis of waste vehicle tyres into fuel provides an alternative method for managing end-of-life vehicle tyres and adding value to waste in general.

Spatial Analysis of Artisanal and Small-Scale Mining in the Tarkwa-Nsuaem Municipality of Ghana
Authors: Kumi-Boateng B. , Stemn E.
Published: July 2020

Abstract

In recent times there have been lots of public outcry on the environmental and public health and safety effects of Artisanal and Small-scale gold Mining (ASM) and the need to monitor ASM activities for reclamation purposes. To effectively develop and deploy policy responses to the environmental and human health effects of ASM, knowledge of the locations and distribution of ASM sites is a prerequisite. However, information regarding ASM hotspots and spatial distribution, the scope and types of ASM operations are hard to find. Therefore, this research was designed to use satellite-based data to map out ASM sites, focusing on the Tarkwa-Nsuaem municipality as the study area. Several image processing techniques were applied on a Landsat 8 satellite image downloaded from the US Geological Survey website. The image processing resulted in the identification of 221 clusters of ASM sites, representing 12.72% of the total size of the study area. To further explore the effects of these ASM sites, Areas of Interest (AOI) including forest reserve, rivers, large-scale mines and urban settlements were defined. By selecting and analysing the location and distribution of the ASM sites in relations to the AOI, the study was effective in identifying environmentally sensitive and critical areas warranting the urgent attention of society to mitigate the health, safety and ecosystem service effects of ASM in the study area. By identifying the environmental sensitive areas being affected by ASM, the findings could support the prioritisation of reclamation efforts.

The role of Civil Society Organisations in post-conflict development of northern Uganda
Authors: Musinguzi Denis
Published: July 2020

This article examines the role of Civil Society Organisations (CSOs) in post-conflict reconstruction and development of northern Uganda. The analysis is informed by the increased spate of violent conflicts in Africa since the end of the Cold War; the destruction caused by violent conflicts; and the significant role played by CSOs in post-conflict reconstruction and development. The northern part of Uganda witnessed the most protracted and devastating Lord‘s Resistance Army (LRA) conflict in the country‘s post-independence history, which forms the central focus of the study. To generate a deeper analysis of the role of CSOs, this article delves into the historical evolution of civil society from the classical thought of ancient Greece to the modern and contemporary perspectives of civil society. The analysis of the role of CSOs in post-conflict reconstruction and development is framed in the war-topeace transition; and recognises the dialectical relationship between peace and development. The article examines the community‘s perceptions on the role of CSOs and its responsiveness to community needs. It concludes with a reflection on simmering issues, which if not properly addressed, could destroy the positive inroads and peace dividends being realised in northern Uganda. A constructivist and qualitative methodology guided the study, which sought to interpret reality from the context of the espondents.

Published: July 2020

The desert's dust and anthropogenic biomass burning's black carbon (BC) in the tropical regions are associated with many effects on climate and air quality. The dust and BC are the selected aerosols, which affect health by polluting the breathable air. This research discusses the effects of both the aerosols, especially while they interact with the clouds. The respective aerosol extinction optical thickness (AOT) extinction was analysed with the sensible heat from Turbulence. The research purposes to quantitatively study the remote sensing data for fine particulate matter, PM2.5, heterogeneously mixing both the dust and the pulverized black carbon's soot or ash, to analyse at which levels PM2.5 can endanger human health in the sub-Saharan region. The mainly analysed data had been assimilated from different remote sensing tools; the Goddard interactive online visualization and analysis infrastructure (GIOVANNI) was in the centre of data collection; GIS, the research data analysis software. In results, the rise and fall of the averaged sensible heat were associated with the rise and fall of averaged aerosol extinction AOT; the direct effects of the selected aerosols on the clouds are also presented. Regarding the health effects, PM2.5 quantities are throughout beyond the tolerably recommended quantity of 25μg/m3; thus, having referred to erstwhile research, inhabitants would consume food and drug supplements which contain vanillic acid during dusty seasons.

Integrating Local Community Perception and Expert’s Knowledge in Spatial Multi-Criteria Evaluation (SMCE) for Landfill Siting in Musanze Secondary City
Authors: Ngwijabagabo H , Nyandwi E , Barifashe T
Published: July 2020

Illegal dumping and landfilling of solid waste is a thoughtful concern nowadays. Solid wastes are disposed in open dumping sites and there is a lack of effective selection of potential and suitable site (s) for landfill, due to the ignorance of all criteria to be integrated in process of decision making. The purpose of this research is to find the most suitable site(s) for the construction of modern landfills using spatial multi-criteria evaluation (SMCE) and addressing the existing gap in involving the local community in the process of siting. Seven criteria of siting were selected combining national and international guidelines for landfill siting criteria. Selected criteria thresholding and ranking decision were grounded on local community preferences. Suitable criteria proximity distances were assessed with a questionnaire survey and further weighted using Expert’s knowledge depending upon their relative importance. Final spatial overlay analysis results showed that the majority of the total area (98.31%) is classified as unsuitable, with 0.05% of the total area being less suitable, 1.21% moderately suitable and only 0.43% of the total area is most suitable. Only 2 sites were found to be qualified as the most suitable and have the capacity of serving at least 10 years. This study is a model for filling the gap of community consultation during the process of landfill siting. It is also a very supportive tool for decision-makers to reduce “Not in my backyard” (NIMBY) phenomenon of waste disposal as well as environmental problems associated with illegal dumping.

Elementy kulturowego obrazu świata jako warunek autonomizacji muzyki
Authors: Moraczewski Krzysztof
Published: July 2020

Cultural images of the world as a condition for the autonomy of music.

The general aim of the essay is to pose the question of the relationship between the elements of a socially shared, general image of the world (using Aaron Gurevich’s terminology) and the possibility of constructing the idea of autonomous music. Musical autonomy is understood here as the thesis that the order of music is independent from any other order, e.g. social, cultural etc. Hence the focus of these considerations is on cultural images of music that situate music beyond external social conditions. Several possibilities of this type are considered, such as the Pythagorean connection between music and the cosmic order, the Iranian concept of Aša, and the ancient Chinese connection between music and the cosmo-political order. Shamanism is considered as a possible archaic source for this kind of mental operation. These considerations do not aim at any kind of archaistic reduction, but rather at describing the cultural-historical conditions that made the very idea of autonomous music possible.

Elementy kulturowego obrazu świata jako warunek autonomizacji muzyki.

Celem artykułu jest postawienie pytania o zależność między elementami społecznie podzielanego, ogólnego obrazu świata (w terminologii Aarona Gurevicha) a możliwością ukonstytuowania idei autonomii muzyki. Autonomia ta rozumiana jest jako teza o niewywiedlności zasad muzyki z odmiennych względem niej porządków: społecznych, kulturowych, itp. Przedmiotem rozważań są zatem takie kulturowe obrazy muzyki, które usuwają ją ze społecznej empirii poprzez powiązanie z porządkiem innego rodzaju. Omówionych zostaje kilka możliwości tego typu, w tym pitagorejskie skojarzenie muzyki z ideą kosmosu, perskie z ideą Aša, czy chińskie z porządkiem kosmogonicznym i politycznym zarazem. Jako możliwe archaiczne podłoże dla tego rodzaju operacji podany zostaje przykład szamanizmu. Celem rozważań nie jest przy tym redukcja autonomistycznego myślenia o muzyce do archaicznych obrazów świata, lecz poszukiwanie historyczno-kulturowych warunków, które umożliwiły późniejszą konstrukcję idei muzyki autonomicznej.
Le récit à la deuxième personne dans l’écriture du malaise. Analyse comparative d’Un homme qui dort de Georges Perec et de L’Inconsolable d’Anne Godard (II partie)

The secondperson narration in the writing of malaise. The comparative analysis of A Man Asleep by Georges Perec and L’Inconsolable by Anne Godard (Part Two)

Suspension between life and death is not the only one that heroes of Gerorges Perec and Anne Godard, accompanied by a reader, have to undergo. The grammatical second person applied in order to represent the characters implies actually a particular plurality of voices which creates in a paradoxical way these two silent heroes. Moreover, devoid of anchor point unlike other grammatical persons, it makes them constantly suspended in time and space. Therethrough, A Man Asleep and L’Inconsolable cannot be treated just like rewritings of common myths: they represent a new quality in the history of literature, very dynamic and rich in interpretations.
Systematic motivation work in the language classroom -	An action research study from southern Norway

Published: July 2020

This study set out to investigate how teachers can support students in developing a metacognitive language-learning strategy that increases intrinsic motivation to learn. To do so, we carried out an intervention where we applied a motivation model in eight language groups in various upper secondary schools. This method focused on identifying goals, success factors, obstacles, as well as making an action plan to succeed with reaching individual goals. Our findings show that the students studying English were more concerned with mastering skills, in particular speaking, whereas the foreign language students were more concerned with performance-based objectives, such as learning grammar and getting good grades. Also, we saw that many of the English students found the approach useful and motivating, whereas most of the foreign language students were somewhat negative to it. As this study involved a limited number of groups, it could be regarded a pilot study. Despite this limitation, we conclude that the method applied in this study may provide a useful tool for developing self-regulated learners, but this needs to be tested in further studies.
El futuro del hombre: ¿Contienen las propuestas del transhumanismo una respuesta satisfactoria?
Authors: Arana Cañedo-Argüelles Juan
Published: July 2020

El artículo expone la evolución de las expectativas acerca del futuro y destino final del hombre tanto a nivel individual como colectivo. Hasta el siglo XVIII predominaban las preocupaciones referidas al destino personal de cada hombre y el significado de la muerte. Tras las revoluciones que acabaron con el antiguo régimen, empezó a dominar el interés por el futuro de la humanidad en su conjunto. Desde mediados del siglo XX hay una preocupación creciente ante el peligro de que la especie humana desaparezca y sea suplantada por otro tipo de entidades, tal vez desarrolladas por el propio hombre. El transhumanismo se ha presentado como una respuesta, basada en la ciencia, a las ansias de supervivencia y mejora del hombre. No obstante, sus propuestas adolecen de varias debilidades, algunas de ellas posiblemente irreparables.

Vehicle ad hoc networks are usually equipped with electronic chips that store a lot of sensitive information. Stores information
related to routing tables, packet, packet header information, uplink and downlink speed. Many studies emphasize on transmission delays,
data redundancy, queue delays and buffer management. The existing scenario collects results while transmitting packets from the source
machine to the destination machine. In the enhanced view, collect results from a remote server located in a rural area. Data was collected
through a cloud-based infrastructure. In this paper, we propose a framework for message propagation and provide security to end to end
semantic. The benefit of this framework is to provide correct information to the end user through cloud technology. This hybrid model is
capable of facilitating communication for cellular based infrastructure. To evaluate the proposed model, we collect the results from the NS2 simulator.
Profil epidemiologique de Wangata,VIH
Authors: Ebengho Bokelo Max
Published: July 2020

En juin 2006, une étude analytique transversale de séroprévalence au Virus de l’Immunodéficience Humaine (VIH) a été initiée au sein du Centre Nutritionnel Thérapeutique (CNT) de l’Hôpital Général de Référence (HGR) de Wangata dans la Province de l’Equateur en République Démocratique du Congo (RDC). Le but de cette enquete était de chercher les possibles signaux existants de l’Infection à VIH sur terrain de malnutrition sévère auprès des enfants de Mbandaka, en collaboration avec la Coordination Provinciale de l’Equateur du Programme National de Lutte contre le VIH-Sida (CP-PNLS). Cette étude s’est basée sur les résultats obtenus suite aux tests volontaires qualitatifs, en se servant de l’algorithme décisionnel de laboratoire du PNLS de 2006 en RDC, qui veut que ces 42 personnes sur lesquelles notre analyse s’est axée soient classifiées dans la catégorie 2. L’étude a tablé sur au moins 2 tests rapides de dépistage, dont le Détermine, un test sensible et l’Oraquick comme test spécifique.
Les résultats obtenus suggèrent que deux enfants de sexe féminin sur les 23 filles en compte avaient un statut sérologique positif, et deux autres également présentaient un résultat indéterminé. La prévalence instantanée était donc de 4,76% pour les enfants malnutris de juin 2006 au CNT de Wangata. Par ailleurs, le Ministère du Plan et de la Reconstruction (MPR) (2018) via le Multiple Indicator Cluster Survey 2001 rapportait une séroprévalence de 6,1% pour la ville de Mbandaka. Ces deux prévalences restent inférieures à 10% et tournent autour des résultats précédents de prévalence tant provinciale que Nationale qui était de plus ou moins 5% (MPR, 2018). Selon Gerstman (2015) dans les choix statistiques tabulaires, il est établi lors de cette étude que les résultats au test sont repartis de façon homogène dans les deux sexes, car avec 1,734 de probabilité calculée comme X², cette valeur étant inférieure à 7,879 de probabilité tabulaire. Par contre les résultats dépendent étroitement du type de test utilize, parce que le CHI-carré (X²) d’indépendance supérieur ou égal à 18,869 est moins significatif que le petit p 0,005 à 7,879 .

Cabozantinib is used for treating different types of cancer. It is available in the market in two different dosage forms with two different trade names. Cabometyx (cabozantinib) is available as 20mg, 40mg and 60mg film coated tablets and is approved by FDA for the management of renal cell carcinoma and hepatocellular carcinoma. However, cometriq (cabozantinib) is available as 20mg and 80mg capsules and is approved by FDA for treatment of thyroid cancer. Availability of two dosage forms for cabozantinib with different trade names for different indications is considered as potential for confusion and prescribing error. Implementation of good prescribing practice is essential in this case.
Successive governments have promoted the prescribing of drugs by generic rather than the trade name. Some drugs should not be prescribed generically for different reasons, for example when dosage forms of the products are not pharmaceutically equivalent. Cabozantinib is an example for this scenario. Cabometyx and cometriq are not bioequivalent.
In conclusion, each institution should have a generic prescribing policy. This policy must include drugs that cannot be prescribed generically. Based on posology, cabometyx and cometriq should not be used interchangeably but in case a patient must switch from cabozantinib capsules to cabozantinib tablets, the patient should continue with cabometyx using a dose not exceeding 60mg or to continue with the current cometriq dose whichever is lower. Do NOT substitute cabometyx tablets with cometriq capsules
Effects of Acetylsalicylic Acid on Non-Alcoholic Fatty Liver Disease – Systematic Review
Authors: Ismaiel Abdulrahman , Al Srouji Nahlah
Published: July 2020

Background: Several studies have assessed the effects of acetylsalicylic acid (ASA), a widely used drug worldwide, in non-alcoholic fatty liver disease (NAFLD) patients. In this systematic review, we aim to evaluate the effect of ASA use on the prevalence of NAFLD, as well as hepatic steatosis and fibrosis in NAFLD patients. Methods: We performed a systematic search on PubMed and Embase electronic databases with predefined keywords searching for observational and experimental studies published from inception and till 19 July 2019. The diagnosis of NAFLD was based on histology, imaging or surrogate markers. Eligible articles based on inclusion and exclusion criteria were extracted and included in the qualitative assessment using the National Heart, Lung, and Blood Institute (NHLBI) quality assessment tools. Results: A total of seven observational studies (5 cross-sectional and 2 cohort) were included involving 18,209 subjects. Three studies evaluated the prevalence of NAFLD in subjects receiving ASA, out of which two studies demonstrated a lower prevalence rate in subjects using ASA for at least ≥ 15 times per month. On the other hand, only one study demonstrated no prevalence decrease in NAFLD with the use of ASA. Moreover, hepatic steatosis and fibrosis was evaluated in four studies with histological confirmation of NAFLD. Two of these studies reported a reduced severity of hepatic steatosis with ASA use. On the other hand, a study demonstrated that a less severe hepatic steatosis but not histological improvement was associated with ASA use. Furthermore, another study reported that ASA use in type 2 diabetic patients wasn’t associated with protective effects against advanced hepatic fibrosis. Statistical pooling of included studies wasn’t performed due to heterogeneity of the study designs. Conclusions: Although most studies demonstrated potential protective effects of ASA use in hepatic steatosis and fibrosis, as well as a reduced prevalence of NAFLD, results from the current literature remain inconsistent with the quality of most studies being rated as fair or poor. Therefore, clear conclusions and recommendations can’t be drawn from the current studies in the literature evaluating this association. Further experimental studies are required to confirm the potential protective effects associated with ASA use on NAFLD.

Subclinical Left Ventricular Systolic Dysfunction Assessed Using Myocardial Strain Measured by Speckle Tracking in Non-Alcoholic Fatty Liver Disease – Systematic Review
Authors: Ismaiel Abdulrahman , Al Srouji Nahlah
Published: July 2020

Background and Aims: Multiple studies demonstrated that non-alcoholic fatty liver disease (NAFLD) is associated with several structural and functional cardiovascular complications. The aim of this systematic review is to evaluate subclinical left ventricular (LV) systolic dysfunction in NAFLD assessed with myocardial strain measured by speckle tracking echocardiography (STE). Methods: We performed a systematic search on PubMed and EMBASE with predefined keywords searching for observational studies published till 19 March 2020. NAFLD diagnosis was accepted if confirmed by biopsy or imaging techniques and LV systolic function evaluation by STE. Full articles that fulfilled our inclusion and exclusion criteria were included in the systematic review. The National Heart, Lung, and Blood Institute (NHLBI) quality assessment tools were used for evaluation of included studies. Results: Eleven observational studies (9 cross-sectional studies, 1 case-control, 1 longitudinal cohort) were included with a total study population of 5,851 subjects. All included studies evaluated left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS). Only two studies rated as “good” demonstrated that NAFLD patients had a reduced LVEF, out of which, one study was conducted on type 2 diabetic patients, while the other study was a population-based longitudinal cohort. Moreover, eight studies, out of which four were rated “good”, two as “fair” and two as “poor” demonstrated that GLS was significantly reduced in NAFLD. On the other hand, the remaining three studies that reported a non-significant difference in GLS were conducted on type 2 diabetic patients in two of the studies, one rated as “fair” and one as “good”. Furthermore, the third study was involving only NAFLD patients comparing drinkers with non-drinkers, being rated as “good”. Conclusions: NAFLD patients are at increased risk to develop subclinical LV systolic dysfunction assessed with myocardial strain measured by speckle tracking, despite having normal LVEF values and remaining asymptomatic. This association remains to be confirmed in more studies involving diabetic patients in the presence and absence of NAFLD.
“Também eram exploradas!”: as mulheres e o Primeiro de Maio em Manaus na década de 1910
Authors: Candido Richard Kennedy Nascimento
Published: July 2020

Neste artigo, temos como objetivo demostrar como as mulheres trabalhadoras da cidade de Manaus participaram das mobilizações do Primeiro de Maio durante a década de 1910. Enfocaremos na trajetória das trabalhadoras da Fábrica de Roupas Amazonense, que empreenderam sucessivas greves na cidade entre 1911 e 1913. A partir da imprensa manauara – tanto jornais operários quanto jornais da chamada grande imprensa –, observamos a participação delas no préstito de 1914 quando foram convidadas a seguir o cortejo. A atuação da imprensa também foi alvo de análise neste artigo, principalmente quando os diversos jornais observados escreveriam de forma distinta acerca da participação dessas mulheres. Contudo, apesar do Primeiro de Maio ser encarado como um tema clássico na historiografia, ele ainda pode ser alvo de novas análises, sobretudo a partir de novas perguntas e abordagens das fontes.
Combining atmospheric and snow radiative transfer models to assess the solar radiative effects of black carbon in the Arctic

Abstract. The magnitude of solar radiative effects (cooling or warming) of black carbon (BC) particles embedded in the Arctic atmosphere and surface snow layer was explored on the basis of case studies. For this purpose, combined atmospheric and snow radiative transfer simulations were performed for cloudless and cloudy conditions on the basis of BC mass concentrations measured in pristine early summer and more polluted early spring conditions. The area of interest is the remote sea-ice-covered Arctic Ocean in the vicinity of Spitsbergen, northern Greenland, and northern Alaska typically not affected by local pollution. To account for the radiative interactions between the black-carbon-containing snow surface layer and the atmosphere, an atmospheric and snow radiative transfer model were coupled iteratively.
For pristine summer conditions (no atmospheric BC, minimum solar zenith angles of 55∘) and a representative BC particle mass concentration of 5 ng g−1 in the surface snow layer, a positive daily mean solar radiative forcing of +0.2 W m−2 was calculated for the surface radiative budget. A higher load of atmospheric BC representing early springtime conditions results in a slightly negative mean radiative forcing at the surface of about −0.05 W m−2, even when the low BC mass concentration measured in the pristine early summer conditions was embedded in the surface snow layer. The total net surface radiative forcing combining the effects of BC embedded in the atmosphere and in the snow layer strongly depends on the snow optical properties (snow specific surface area and snow density).
For the conditions over the Arctic Ocean analyzed in the simulations, it was found that the atmospheric heating rate by water vapor or clouds is 1 to 2 orders of magnitude larger than that by atmospheric BC. Similarly, the daily mean total heating rate (6 K d−1) within a snowpack due to absorption by the ice was more than 1 order of magnitude larger than that of atmospheric BC (0.2 K d−1).
Also, it was shown that the cooling by atmospheric BC of the near-surface air and the warming effect by BC embedded in snow are reduced in the presence of clouds.

Abstract. Having a common framework for early action to cope with
complex disasters can make it easier for authorities and other stakeholders,
including populations at risk, to understand the full spectrum of secondary
and tertiary effects and thus where to focus preparedness efforts, and how
best to provide more targeted warnings and response services. Meteorological
and hydrological services world-wide have developed and implemented
Multi-Hazard Early Warning Systems (MHEWS) for weather and climate related
hazards that are now being expanded and transitioned towards Multi-Hazard
Impact-based Early Warning Systems (MHIEWS). While it is still early days it
is becoming clear that there are useful lessons from this approach in the
COVID-19 global pandemic, and some valuable insight to be gained in risk
communication, risk analysis and monitoring methodologies and approaches.
The ability to understand and respond effectively to warnings through
appropriate behaviours and actions is central to resilient societies and
communities. By avoiding physical, societal and economic harm to the
greatest extent possible, recovery from a hazard is likely to be faster,
less costly and more complete. MHIEWS can be a common approach for all hazards and therefore more likely to
become a trusted tool that everyone can understand and use as a basic
element of their national disaster risk management system. The
interconnectedness of hazards and their impacts is a strong motivator for a
common approach. One of the lessons from the COVID-19 pandemic and extreme
weather events is the need to understand the vulnerability of individuals,
communities and societies so as to provide reliable, targeted guidance and
warnings and the willingness and capacity to prepare for a reasonable
worst-case scenario based on informed long-term planning. Meteorology and
hydrology are making good progress in this direction and the process can be
readily applied to health and other sectors.
