Published: July 2021

The high-redshift quasar PMN J0909+0354 (z = 3.288) is known to have a parsec-scale compact jet structure, based on global 5 GHz very long baseline interferometry (VLBI) observations performed in 1992. Its kiloparsec-scale structure was studied with the Karl G. Jansky Very Large Array (VLA) in the radio and the Chandra space telescope in X-rays. Apart from the north-northwestern jet component seen in both the VLA and Chandra images at 2.″3 separation from the core, there is another X-ray feature at 6.″48 in the northeastern (NE) direction. To uncover more details and possible structural changes in the inner jet, we conducted new observations at 5 GHz using the European VLBI Network in 2019. These data confirm the northward direction of the one-sided inner jet already suspected from the 1992 observations. A compact core and multiple jet components were identified that can be traced up to ∼0.25 kpc projected distance toward the north, where the structure becomes more and more diffuse. A comparison with arcsecond-resolution imaging with the VLA shows that the radio jet bends by ∼30° between the two scales. The direction of the parsec-scale jet as well as the faint optical counterpart found for the newly detected X-ray point source (NE) favors the nature of the latter as being a background or foreground object in the field of view. However, the extended (∼160 kpc) emission around the positions of the quasar core and NE detected by the Wide-field Infrared Survey Explorer in the mid-infrared might suggest a physical interaction of the two objects.

Published: July 2021

The taxonomic status of the Thai populations belonging to the Limnonectes kuhlii species complex is controversial, due to phenotypic similarity in the cryptic species complex. Recently, some studies on this group in Thailand have discovered four new species: L. taylori, L. megastomias, L. jarujini and L. isanensis. Even so, the diversity of this group is still incomplete.

Based on an integrative approach encompassing genetic and morphological analyses, we conclude that the Limnonectes populations from Nan Province (northern) and Yala Province (southern) of Thailand are conspecific with L. bannaensis Ye, Fei & Jiang, 2007 and L. utara Matsui, Belabut & Ahmad, 2014, respectively. These are the first records of these species in Thailand. Our study highlights the importance of using DNA sequence data in combination with morphological data to accurately document species identity and diversity. This is especially important for morphologically cryptic species complexes and sympatrically occurring congeners.

Les interventions extra-européennes de la Unión Libéral (1856-1868). Une tentative d’impérialisme informel ?
Authors: Inarejos Muñoz Juan Antonio
Published: July 2021

D’une manière générale et comme l’a habituellement postulé l’historiographie qui a traditionnellement abordé la politique extérieure de la seconde moitié du règne d’Isabelle II (1856-1868), les interventions armées de cette époque ont été interprétées d’une manière romantique, « donqui-jotesque » et sans objectifs définis. Cette série de lieux communs sera discutée dans cet article qui aura pour but de retracer les causes qui favorisèrent les conflits auxquels l’Espagne participa à cette époque et l’impact qu’ils eurent dans la formalisation et la diffusion de discours nationalistes. Le schéma analytique de l’article s’efforce de présenter les débats que suscitèrent les stratégies à adopter au sujet des alliances de l’Espagne avec les principales puissances européennes de l’époque (l’Angleterre victorienne et la France de Napoléon III) et de la défense de ses intérêts impérialistes formels et informels.
Race, nationalité et travail maritime en Côte française des Somalis (1896-1952)
Authors: Joll Laurent
Published: July 2021

Escale maritime sur les lignes de paquebots de l’océan Indien et d’Extrême-Orient, Djibouti devient pour la marine marchande française, tout particulièrement la Compagnie des Messageries Maritimes, un point d’avitaillement obligé en combustible mais aussi en main-d’œuvre pour les salles des machines des navires à vapeur. Les pratiques d’embauche des Messageries Maritimes, entreprise intimement liée au développement du port de la Côte française des Somalis, privilégient une main-d’œuvre originaire du Yémen conformément au racialisme en vogue en Europe et sont à l’origine d’une compétition durable entre les différentes composantes ethniques de la ville. Leur remise en cause au nom de la nationalité impériale nous révèle en outre l’agentivité du dominé capable d’utiliser les contradictions d’une situation coloniale particulière, et de la faire évoluer.
Adolphe Messimy (1869-1935), un colonial méconnu
Authors: Robinne Christophe
Published: July 2021

Ancien officier de l’armée active poussé à la démission en 1899, en raison de son activisme dreyfusard, Adolphe Messimy est élu à l’Assemblée nationale en 1902. Il ne tarde pas à se faire connaître pour ses prises de position en faveur de l’Empire colonial. Éphémère ministre des Colonies en 1911, Messimy inscrit sa réflexion globale sur l’avenir de l’Empire et demande que l’œuvre économique et industrielle de la colonisation soit complétée par une œuvre morale, sociale et politique. En 1919, à l’issue de la Grande Guerre, le général Messimy, ayant perdu son siège de député, entre au sein de nombreux conseils d’administration de sociétés liées à l’empire. À partir de 1923, élu au Sénat, il s’engage pour le développement de l’agriculture coloniale, de l’enseignement colonial puis de la création d’un fonds national pour l’outillage public de la France d’outre-mer.
Sur l’expression Pieds-Noirs : une mise au point historico-sémantique
Authors: Ruscio Alain
Published: July 2021

Les origines et les destinées de l’expression familière Pieds-Noirs sont depuis longtemps source d’interrogations. Des explications hasardeuses ont fleuri depuis plus de 60 années, sans jamais reposer sur des sources fiables. Fort heureusement, des travaux sérieux ont déjà exploré la question. Il a paru nécessaire de les synthétiser, puis de les compléter par des sources nouvelles. On a pu ainsi situer de façon assez précise la naissance (dans les sources écrites) de l’expression : en 1955, au Maroc (et non en Algérie, comme il est généralement pensé). Puis, durant et après la guerre d’Algérie, l’expression s’est imposée pour désigner les rapatriés venus de la rive sud de la Méditerranée.

Une autre façon de posséder. Réflexions historico/juridiques sur les aménagements fonciers en Italie
Authors: Grossi Paolo
Published: July 2021

Dans sa contribution Paolo Grossi propose des réflexions d’ordre historico-juridique sur les aménagements fonciers collectifs en Italie et montre comment, à travers la jurisprudence constitutionnelle et l’adoption de la loi n°168 du 20 novembre 2017, le droit italien a finalement reconnu leur autonomie juridique et retrouvé ainsi son pluralisme et sa complexité. De tels régimes juridiques contribuent à la protection de l’environnement.
Parents suspects. Stratégies de contrôle des personnes étrangères parents d’enfants français
Authors: Carayon Lisa
Published: July 2021

Les parents étrangers d’enfants français font, depuis plusieurs années, l’objet d’une suspicion de plus en plus importante de la part des administrations de l’immigration sur la « réalité » de leur filiation ; et partant sur la réalité de leur droit au séjour sur le territoire français. Les conséquences de cette suspicion sur la production du droit sont particulièrement sensibles depuis le début des années 2000 : une analyse de l’évolution de la législation, adjointe à une observation des pratiques préfectorales, permet de montrer que, partie d’une méfiance à l’égard des pères étrangers elle s’étend aujourd’hui aux mères.
Les femmes et les enfants d’abord. Normes familiales, tri et réinstallation de réfugiés
Authors: Mottet Aurore
Published: July 2021

Cet article se propose de revenir, à la fois dans une perspective historique et ethnographique, sur la manière dont les enjeux familiaux ont parcouru la procédure de réinstallation de réfugiés mise en place par le Haut-Commissariat des Nations-Unies pour les Réfugiés (ci-après HCR) depuis les années 1950. Il s’agira d’interroger à la fois comment le personnel du HCR mobilise localement des critères familiaux pour déterminer le mérite et le besoin d’être réinstallé et la manière dont, pris dans ce cadre législatif contraignant et son application locale, les réfugiés s’en saisissent et le détournent, parfois dans une dynamique de « détournement forcé », et parfois selon les normes de genre qui régissent l’ordre familial. Basée sur la consultation et l’analyse d’archives du HCR, la première partie de l’article reviendra sur l’évolution de la procédure de réinstallation qui consiste à sélectionner certains réfugiés dans leur pays d’asile pour ensuite les réinstaller dans un pays tiers qui accepte de les accueillir durablement. La réinstallation ne concerne aujourd’hui qu’un très petit nombre de réfugiés et s’adresse quasi-exclusivement à des profils vulnérables construits autour de figures familiales spécifiques (femmes seules, avec ou sans enfants, mineurs isolés, etc.) dont les hommes sont en partie exclus. Dans le cadre de cette restriction des places disponibles, les enjeux familiaux sont centraux au cours de la sélection. Basée sur une enquête ethnographique multi-située depuis le Maroc vers le Canada, cet article interroge l’ensemble de la procédure de réinstallation, la manière dont s’établissent des frontières légitimes ou illégitimes entre des réfugiés à réinstaller ainsi que la manière dont est perçue, mobilisée et détournée cette procédure par les réfugiés qui redessinent les contours de leurs cadres familiaux pour accéder à cette ressource rare.
La laïcité à cheval sur le public et le privé
Authors: Delgrange Xavier
Published: July 2021

Cet article évoque certaines évolutions de la laïcité pour illustrer le brouillage de la frontière entre le droit public, droit de l’autorité, et le droit privé, droit de la liberté. La laïcité s’impose à l’État afin de protéger la liberté et l’égalité des citoyens. Invoquant la liberté d’entreprendre, les entreprises privées se déclarent neutres afin de restreindre la liberté religieuse de leur personnel. De son côté, les écoles publiques revendiquent la liberté d’enseignement, réservée au libre, pour restreindre la liberté religieuse des professeurs et des élèves sans y être habilités par le législateur, au mépris du principe constitutionnel de légalité.
L’artiste et la grâce du Christ
Authors: Hétier Denis
Published: July 2021

Lorsque le théologien d’Innsbruck propose de discerner des expériences de la grâce, il fait appel aux diverses expériences de la vie en lesquelles notre esprit se dévoile dans sa transcendance propre. Or l’expérience artistique est précisément un lieu concret où peut se vivre cette transcendantalité de l’esprit. Plus encore l’expérience proprement créatrice, parce qu’elle est un acte fondamentalement libre, place inéluctablement l’artiste sous l’offre universelle de la grâce du Christ en tant que celle-ci est un existential permanent de l’homme. L’artiste, s’exprimant à partir de lui-même, peut être ainsi témoin, ne serait-ce qu’anonymement, de l’événement de la grâce. Ces réflexions rahnériennes sur l’art supposent une compréhension de la sensibilité dans son unité indivise avec l’esprit et son ouverture à un horizon infini.
Incarnation et grâce
Authors: Baudin Claire-Anne
Published: July 2021

Par la façon dont il unit l’anthropologie à la christologie, Karl Rahner invite à considérer l’ensemble de la création et du salut dans un même mouvement. Il s’agit toujours, dans sa théologie, de cette « violence inouïe de l’amour de Dieu » qui s’offre à l’histoire, et de la libre volonté de l’homme qui, par grâce, souvent, s’y allie. Par union entre l’amour qu’est Dieu et la libre détermination de soi qu’est l’homme se construit tout ce qui vit véritablement et tout ce qui demeure – le Christ lui-même. C’est là l’unique réalité qui vaille : l’incarnation de la grâce, qui forme l’histoire, selon le mouvement de l’Union hypostatique et la personne historique de Jésus-Christ. Le rapport de la grâce à l’incarnation dessine un centre interprétatif de la théologie de Karl Rahner et en permet une approche cohérente. La constance de ce fondement apparaît dans tous les textes du corpus. Rahner lui-même cerne et rappelle régulièrement l’audace de cette approche, dont la théologie contemporaine n’a pas fini de tirer profit.
Karl Rahner et l’œcuménisme : un plaidoyer pour l’audace
Authors: Chalamet Christophe
Published: July 2021

L’engagement et le souci œcuméniques de Karl Rahner ne sont plus à démontrer. Il demeure toutefois intéressant et important d’en préciser les contours, au fil d’une œuvre où le thème de la grâce représente une sorte de fil rouge tout sauf marginal. La présente contribution s’attache à trois aspects de cette œuvre, à savoir la question du thème ou de l’objet même de la théologie, la question de la grâce incréée et créée, et enfin les audacieuses thèses de Rahner et de Fries sur l’unification des chrétiens.
Transient thermal characteristics of infrared window coupled radiative transfer subjected to high heat flux
Authors: Pan Hong-Yu ,   School of Energy Science and Engineering, Harbin Institute of Technology, 92, West Dazhi Street, Harbin 150001, PR China, Sun Chuang , Chen Xue
Published: July 2021

In infrared detection system on aircrafts, the infrared window, as an essential part, always faces heating condition generated by aerodynamic effects. The accurate thermal analysis can ensure the safety and reliability of internal detection system. In this work, the transient thermal characteristics of infrared window-based encapsulation structure are investigated under a high heat flux loading. The physical model of coupled radiative-conductive heat transfer in the window is established while the spectral selectivity of the window to thermal radiation is considered. The transient temperature response is used to evaluate the thermal characteristics. The effect of the radiative heat transfer is firstly analyzed and compared with the pure heat conduction model. There is a temperature deviation (74.1 K) when the radiative heat transfer is ignored. Subsequently, the transient temperature response is simulated under three different kinds of heat flux respectively. It is found that the effect of external heat flux loading is significant. The highest temperature difference reaches 32.9% (299 K) when the heat flux is reduced by 0.5 times and achieves 86.3% (794 K) when the heat flux is increased by 2.5 times. Moreover, the geometric dimensions of window (shape of a truncated cone) generate an effect on its heat transfer characteristics. The temperature decreases significantly (37.8%) when the thickness rises from 10 mm to 20 mm (r = 25 mm) while the temperature decreases relatively small (8.1%) when the radius increases from 15 mm to 45 mm (d = 15 mm). The results reveal that the radiative heat transfer in the window should be carefully considered, especially under the high heat flux loading. Additionally, reducing heat flux or thickening window can improve insulation effectiveness so as to ensure the stable working of the internal equipment.
New methods based $ \mathcal{H} $-tensors for identifying the positive definiteness of multivariate homogeneous forms
Authors: Bai Dongjian ,   College of Data Science and Information Engineering, Guizhou Minzu University, Guiyang, Guizhou 550025, China, Wang Feng
Published: July 2021

Positive definite polynomials are important in the field of optimization. $ \mathcal{H} $-tensors play an important role in identifying the positive definiteness of an even-order homogeneous multivariate form. In this paper, we propose some new criterion for identifying $ \mathcal{H} $-tensor. As applications, we give new conditions for identifying positive definiteness of the even-order homogeneous multivariate form. At last, some numerical examples are provided to illustrate the efficiency and validity of new methods.
Specification tests for non‐Gaussian maximum likelihood estimators
Authors: Fiorentini Gabriele , Sentana Enrique
Published: July 2021

We propose generalized DWH specification tests which simultaneously compare three or more likelihood‐based estimators in multivariate conditionally heteroskedastic dynamic regression models. Our tests are useful forGarchmodels and in many empirically relevant macro and finance applications involvingVars and multivariate regressions. We determine the rank of the differences between the estimators' asymptotic covariance matrices under correct specification, and take into account that some parameters remain consistently estimated under distributional misspecification. We provide finite sample results through Monte Carlo simulations. Finally, we analyze a structuralVarproposed to capture the relationship between macroeconomic and financial uncertainty and the business cycle.
Rationalizing rational expectations: Characterizations and tests
Authors: D'Haultfoeuille Xavier , Gaillac Christophe , Maurel Arnaud
Published: July 2021

In this paper, we build a new test of rational expectations based on the marginal distributions of realizations and subjective beliefs. This test is widely applicable, including in the common situation where realizations and beliefs are observed in two different data sets that cannot be matched. We show that whether one can rationalize rational expectations is equivalent to the distribution of realizations being a mean‐preserving spread of the distribution of beliefs. The null hypothesis can then be rewritten as a system of many moment inequality and equality constraints, for which tests have been recently developed in the literature. The test is robust to measurement errors under some restrictions and can be extended to account for aggregate shocks. Finally, we apply our methodology to test for rational expectations about future earnings. While individuals tend to be right on average about their future earnings, our test strongly rejects rational expectations.

Application of Dynamic Image Fusion Technology in Development of Innovation Capabilities of College Students Majoring in Art Design
Authors: Wang Zhe
Published: July 2021

Art design is based on art and images, in which dynamic images require pre-processing and fusion. This paper explores how to apply the dynamic image fusion technology in the development of the innovation capabilities of college students majoring in art design. The research results show that image sequences with different exposures can be directly formed into low dynamic range images through multi-exposure fusion, or the high dynamic range can be restored first, and then converted to a low dynamic range image through tone mapping. The main principles for innovation development in art design education include conformity, student-centeredness, and overall optimization. The dynamic image fusion enhancement algorithm is mainly divided into five functional modules, which are used to calculate multi-scale gradient, structure tensor, and target gradient for the fused image, solve the steepest descent method and output normalized images, respectively

Authors: Rungrangtanapol Noppadol , Khlaisang Jintavee
Published: July 2021

In the 21st century, computing and other necessary skills have become imperative for today's learners. Memorizing a book or one-way communication is incapable of fully developing all the skills required. Along with changes in the new curriculum structure in the computational science courses which are aimed to improve computational thinking skills. In Thailand, students do not have enough experience in calculation methods. Teachers must therefore provide instruction in a format that promotes computational thinking and the skills necessary for the 21st century. The sample was 400 students from public and private schools in the same amount to develop the model, which was calculated based on the population of high school students throughout Bangkok, Thailand. It was found that the current learning model was unable to develop computational thinking concepts and 21st century skills. Therefore, the researchers have the concept of developing a teaching model that focuses on problem-solving along with the use of a design thinking approach in a virtual learning environment. To enable students with no experience with computational thinking skills to develop computational thinking skills to a competent standard. The objective is to also develop other skills, which are essential skills in the 21st century at the same time.

Since the emergence of the Coronavirus and its declaration as a global pandemic, the world has changed all sectors radically. Covid-19 has caused a very strong effect on daily life and adaptation to new ways of learning, working, and communicating. The smart city is one of the most important solutions that enable us to go on with daily life during the pandemic and beyond. The smart city employs the current technology and smart solutions to serve the community, and improve the services provided to the people, particularly in vital sectors such as health, education, electricity, transportation, communications, and others. This article deals with two innovative applications for the Internet of things in smart cities: The first refers to designing an intelligent health monitoring system, which aims to reduce the spread of Coronavirus infection from people to the medical staff, as well as reduce work pressure on the medical staff. The second application refers to monitoring electrical energy consumed by measuring and monitoring electrical parameters and energy consumption. In addition, it helps us to know the power line trespasser. Both systems are implemented by using sensors to gather data in real-time and then transmit it to the server.

Published: July 2021

Since health-related information for pregnant women is extremely complex and sensitive, end-users of any application are required to have the same level of knowledge as the information providers to help them to navigate between various sources of information to ascertain the reliability of contents that are often confusing. However, although there are several such applications for Thai pregnant women in the market, few were developed based on research evidence.

 This study is focused on the design of a health application specifically for Thai pregnant women by extracting the explicit problems of existing applications and providing solutions to them. A design thinking methodology comprised of empathise, define, ideate, prototype and test was used as a guideline to develop a prototype app. IT experts, physical therapists and pregnant women were recruited as participants to address the problem taxonomy and obtain a solution.

The new application produced in this study with the aim of encouraging pregnant women especially for Thai women to engage in physical activity was based on research, and the input of physical therapists, IT experts and pregnant women users was able to feasibly inform the development of an acceptable and usable mobile health application for pregnant women.
« Danser la relation »
Authors: Mazzella di Bosco Marie
Published: July 2021

« Se connecter à soi, à l’autre, aux autres et au monde » : ainsi est souvent présentée l’ambition de « danses libres en conscience » telles que la Danse des 5 Rythmes. Délaissées par les communautés scientifiques ou artistiques, on peut pourtant considérer ces pratiques comme des laboratoires d’expérimentation relationnelle où est en jeu quelque chose qui dépasse à la fois le mouvement dansé et la simple démarche de bien-être. La danse y est l’instrument d’une construction de modes relationnels particuliers : par le corps en mouvement, de subtiles négociations interpersonnelles se jouent, supports d’enjeux relationnels plus larges, et fondamentaux si l’on prête attention aux témoignages et actions des danseurs. Dans une brève ethnographie des gestes, postures et perceptions sensorielles à l’œuvre, cet article tente d’analyser la façon dont les interactions dansées sont induites, amorcées, développées, interprétées, et ainsi d’éclairer la nature de ces modes relationnels propres à la danse.
Être dansé
Authors: Zeghmar Lydia
Published: July 2021

Dans l’arrière-pays égéen en Turquie, le répertoire musical et chorégraphique zeybek célèbre l’héroïsme de rebelles maquisards de la période ottomane, les efe. Dans cette contribution, je propose d’analyser un temps particulier de la performance dansée zeybek appelé « promenade ». Avant d’entrer pleinement dans la danse, le soliste effectue une marche improvisée de quelques dizaines de secondes pendant laquelle il s’accorde avec les musiciens et recherche l’état de danse. Pour qualifier ce moment transitionnel, les danseurs de zeybek portent l’emphase sur l’âme et le tempérament du danseur. Je propose de décrire les différentes composantes de ce processus de mise en état du danseur et d’éclairer ses significations. Nous étudierons comment la promenade contribue à jeter le trouble sur l’identité de la personne qui est dansée à travers la mise en œuvre d’une liminarité : entre la marche et la danse, entre la personne du danseur et le personnage du efe.
A clinico-epidemiological profile study of venereal genital dermatoses in a tertiary hospital in southern Nigeria: A 5-year review
Authors: Roli Madubuko Cynthia , Ademola Adejumo Oluseyi
Published: July 2021

Venereal genital dermatoses are cutaneous morbidities contracted and transmitted by sexual contact. They are caused by microorganisms that survive on the skin or mucous membranes, or that are transmitted via semen, vaginal secretions, or blood during sexual intercourse. Data on pattern of presentation and diagnoses of venereal genial dermatoses are limited in Nigeria. The aim of this study was to determine the pattern of presentation of venereal genital dermatoses over a 5-year period in the University of Benin Teaching Hospital (UBTH), Benin City, Edo State, Nigeria. Information extracted from patients’ medical records included socio-demographic data, duration of symptom, distribution of lesions, symptomatology and diagnoses of the venereal genital dermatoses. There were 121 patients with venereal genital dermatoses amongst 1600 new cases seen over the 5-year period constituting a prevalence of 7.6%. The male:female ratio of the study population was 1.5:1 and their mean age was 26.2 ± 10.5 years. The predominant symptoms at presentation were abnormal genital growth in 108 (89.3%), genital ulcer in 12 (9.9%), and genital pain in 11 (9.1%). The common venereal genital dermatoses were anogenital warts in 108 (89.3%) and genital herpes in 11 (9.1%). Venereal genital dermatoses are a relatively common dermatological presentation in UBTH and anogenital wart was the most common type. Venereal genital dermatoses were more common in the young age group and males. The most predominant site of affectation was the vulva in females and penis in males.
Diatom communities and ecological status classification in the upper Po River basin

Published: July 2021

One of the main challenges in river management is the setting of nutrient thresholds that support good ecological status, which is the main objective to achieve for the European member states. This is a complex process, which needs an accurate analysis of the data collected so far for the ecological classification of rivers belonging to different typologies. We analysed the data of the multiannual monitoring concerning diatoms and nutrients in the upper Po River (NW Italy) with the aim of exploring the response of diatom community in terms of species composition, ecological guilds and indices. We considered data of 390 samples, of which 2/3 belonging to the “Central macrotype” (i.e. lowland stretches) and 1/3 to “Alpine siliceous”. We performed a Principal Coordinate Analysis to detect community patterns with respect to water chemical classification and macrotypes highlighting species and ecological guilds characteristic of samples along a water quality gradient. We then performed a partial RDA to focus on the role of environmental and spatial factors in shaping the diatom community in each of the two macrotypes. Finally, we investigated the concordance between the Italian normative indices ICMi (for diatoms) and LIMECO (a chemical index of water quality). We found significant differences in the diatom communities of the two macrotypes and in their response to water quality and to spatial factors. Communities resulted as much more uniform in sites with a low water quality, with characteristic species such as Navicula gregaria, Nitzschia palea and Sellaphora nigri. On the other hands, moderately disturbed sites (in terms of trophic level) were characterised by the highest guild diversity. The RDA confirmed the importance of spatial factors in shaping the diatom assemblages, especially in Alpine streams where the physical barriers may condition species dispersion. The comparison between the two normative indices highlights that the correspondence in the classification is achieved in the 57% (Alpine macrotype) and 43% (Central macrotype) of samples. According to our findings, we suggest the revision of the ICMi, both class boundaries and reference value. In addition, we recommend to lower LIMECO threshold for total phosphorus: indeed, several studies have shown significant changes in the diatom community composition starting from very low values (below the current LIMECO threshold, i.e. 50 µgL-1). Moreover, the extension of our study to the whole Po River basin will complete our knowledge of species not yet included in the diatom indices and of the community response to nutrient levels also in other macrotypes.
Obstructive Sleep Apnea and Periodontitis
Authors: Mukherjee Suman , Galgali Sushama R.
Published: July 2021

Objectives:

(1) To assess the risk of Obstructive Sleep Apnea (OSA) using a pre-designed questionnaire; (2) To assess the periodontal parameters like pocket probing depth (PPD) and clinical attachment loss (CAL) in the study subjects and (3) To determine the association between the shared risk factors of OSA and periodontitis.

Background of the Study:

Periodontitis is a microbially associated, host-mediated inflammatory disease that results in the loss of periodontal attachment. It has multifactorial etiology and has been linked to an array of systemic diseases. Though both periodontitis and obstructive sleep apnoea (OSA) share some common risk factors, the insight into the hypothetical speculative link remains vague. This study intended to probe into the association between periodontitis and OSA.

Methodology:

A cross-sectional study was conducted on 250 subjects. The subjects were explained the nature of the study and written informed consent was obtained for participation in the study. The patients were administered a STOP-BANG questionnaire following which the periodontal parameters were recorded. The data obtained was analyzed by descriptive and inferential statistics.

Results:

A statistically significant increase in PPD and CAL scores were seen with the increase in OSA scores. A significant moderate positive correlation was found between OSA scores and PPD [r = 0.58, P < 0.001] and CAL [r = 0.55, P = 0.001]. Males were at increased risk for OSA and periodontitis. Age, hypertension and BMI which are the risk factors for periodontitis were also significantly higher in subjects at high risk for OSA.

Conclusion:

This study found a moderate positive association between periodontitis and OSA.

Authors: Kumar Vanktesh , Kaur Navjot , Wadhwa Pankaj
Published: July 2021

Crocus sativus L., a member of the Iridaceae family, commonly known as saffron has very much popular as both medicine and spice. Earlier saffron was used as one of the important constituents in opioid preparations for pain relief. Its uses in the treatment of mild-to-moderate depression are well documented. Depression can affect the quality of life of individuals by causing headaches, difficulty in thinking, and loss of interest. Many clinical trials have been conducted for evaluating the efficacy of saffron in depression cases. Almost fifty constituents of C. sativus L are well known. Few of the major constituents include crocin, picrocrocin, and safranal. In the present review, the main focus is on the antidepressant effects of saffron and its major constituents, in which it was found that saffron has substantial effects on depression and anxiety because of double-blind study the data can be trusted.
Localized regularity of planar maps of finite distortion
Authors: Hirviniemi Olli , Prause István , Saksman Eero
Published: July 2021

In this article we study fine regularity properties for mappings of finite distortion. Our main theorems yield strongly localized regularity results in the borderline case in the class of maps of exponentially integrable distortion. Analogues of such results were known earlier in the case of quasiconformal mappings. Moreover, we study regularity for maps whose distortion has better than exponential integrability.

OBJECTIVES: This study aimed to examine the prevalence of psychiatric disorders among Egyptian healthcare workers (HCWs) during the coronavirus disease 2019 (COVID-19) pandemic.METHODS: Six databases were searched for relevant papers. The quality of the selected articles was measured using the National Institute of Health quality assessment tool. We used a fixed-effects model when there was no heterogeneity and a random-effects model when there was heterogeneity.RESULTS: After screening 197 records, 10 studies were ultimately included. Anxiety was the most commonly reported psychiatric disorder among HCWs, with a prevalence of 71.8% (95% confidence interval [CI], 49.4 to 86.9), followed by stress (66.6%; 95% CI, 47.6 to 81.3), depression (65.5%; 95% CI, 46.9 to 80.3), and insomnia (57.9%; 95% CI, 45.9 to 69.0). As measured using the 21-item Depression, Anxiety, and Stress Scale, the most common level of severity was moderate for depression (22.5%; 95% CI, 19.8 to 25.5) and stress (14.5%; 95% CI, 8.8 to 22.9), while high-severity anxiety was more common than other levels of severity (28.2%; 95% CI, 3.8 to 79.6).CONCLUSIONS: The COVID-19 pandemic has had a negative effect on Egyptian HCWs’ psychological well-being. More psychological support and preventive measures should be implemented to prevent the further development of psychiatric illness among physicians and other HCWs.
Preventable causes of cancer in Texas by race/ethnicity: tobacco smoking
Authors: Gudenkauf Franciska J. , Thrift Aaron P.
Published: July 2021

OBJECTIVES: Tobacco smoking is classified as carcinogenic to humans (International Agency for Research on Cancer Group 1). We aimed to estimate the percentage and number of incident cancer cases diagnosed in Texas in 2015 that were attributable to tobacco smoking, and we examined differences in the proportions of smoking-attributable cancers between the major racial/ethnic subgroups of the population.METHODS: We calculated population-attributable fractions for cancers attributable to tobacco smoking using prevalence data from the Texas Behavioral Risk Factor Surveillance System and relative risks associated with smoking status from pooled analyses of cohort studies or meta-analyses. Cancer incidence data were collected from the Texas Cancer Registry.RESULTS: We estimated that 19,000 excess cancer cases or 18.4% of all cancers diagnosed in 2015 in Texans aged ≥ 25 years were caused by tobacco smoking. Males had a higher overall proportion of cancers attributable to tobacco smoking than females (male, 23.3%, 11,993 excess cases; female, 13.5%, 7,006 cases). Approximately 20% of cancer cases in non-Hispanic Whites and non-Hispanic Blacks were attributable to tobacco smoking compared to 12.8% among Hispanics.CONCLUSIONS: Despite ongoing public health campaigns combatting tobacco use, this preventable behavior still contributes significantly to cancer incidence in Texas. Racial/ethnic differences in smoking prevalence and smoking-attributable cancer incidence should be considered when designing cancer prevention programs.

There are many existing Low Impact Development (LID) applications available to calculate stormwater runoff volume, but they often fail to address LID systems in the initial design stages. To address this problem a LID application was developed for international use that supports designers considering how to reduce stormwater runoff through LID strategies. The result is an iterative design process that allows designers to visualize results. This helps users make informed decisions when it comes to stormwater management practices that are based on a combination of readily available local climate data and existing site conditions to create preliminary runoff results.

Introdução: O acompanhamento dos escolares quanto a instalação do excesso de peso é de fundamental importância, visto os problemas que podem decorrer desse excesso na vida adulta. Objetivo: O presente estudo analisou o índice de massa corporal de estudantes de uma escola privada do interior do Pará, no período de 3 anos. Métodos: Participaram do estudo 269 alunos de 6ª a 8ª série, matriculados de 2011 a 2013. Os estudantes foram divididos em três grupos para serem avaliados: o G1 (alunos avaliados da 6ª à 8ª série); o G2 (alunos avaliados da 7ª à 9ª série); e o G3 (alunos avaliados da 8ª série ao 1º ano). Os escolares foram avaliados quanto à massa corporal, estatura e índice de massa corporal (IMC). Os dados foram analisados quanto à normalidade e adotou-se a correlação de Pearson para os dados paramétricos e de Spearman para os dados não paramétricos. O nível de significância adotado foi de p<0.05 e o software utilizado foi o Graphpad Prism. Resultados: Foi observado nos resultados correlação positiva para estatura e massa corporal nos 3 grupos e do IMC para o G2, além do mais,houve redução no sobrepeso/obesidade de 8% no G1 ao longo dos 3 anos, de 5% do sobrepeso/obesidade no G2 e no G3 foi notada a menor redução no excesso de peso, 2%. Conclusão: Conforme o método proposto, que o excesso de peso entre os estudantes, no período de 3 anos, oscilou de 28% a 37%, com predomínio de obesidade no gênero masculino.

Published: July 2021

No decorrer de sua gênese, o corpo passa por mutações que são influenciadas muitas vezes por fatores externos a sua vontade. Desta maneira o sujeito, sob várias influências, constrói sua identidade corporal baseada na vivência de suas sensações, sentidos e tomada de consciência. Com a atual busca por saúde enquanto ideal estético há modificações no modo de viver que atribui felicidade e completude a determinados padrões corporais. O objetivo do texto é propor reflexões acerca da valorização do culto ao corpo na construção da identidade, assim como da imagem corporal. Trata-se de uma revisão narrativa em forma de ensaio que estabelece relações com a atualidade, com temáticas recorrentes e novas perspectivas, contribuindo para o conhecimento e formação de profissionais envolvidos com a temática.A busca por imagens corporais de sucesso desperta desejos nos indivíduos que, por seguirem tendências socioculturais, acreditam carecer de modificações constantes nos corpos, neste caminho notável pela aprovação da beleza a figura do corpo modelo é superexplorada. Por imagem corporal entende-se a figura do próprio corpo formada pelo sujeito, podendo ser produzida de forma positiva ou negativa. Sua forma positiva apresenta resultantes de melhorias na saúde global, as negativas podem culminar em insatisfações e alterações na percepção do corpo acarretando transtornos prejudiciais à saúde. O trabalho reforça medidas de promoção de saúde e prevenção de transtornos à medida que há crescente insatisfações com a imagem, principalmente em grupos jovens de sexo feminino, muitas vezes criado pelo consumismo que incita necessidades de constantes transformações e adaptações corporais.
