Authors: Masfria Masfria , Marianne Marianne , Permata Yade Metri
Published: January 2020

BACKGROUND: Rhaphidophora pinnata (L.f.) Schott is one of the Indonesian plants, has known as a medicinal plant. This plant is a vine; round stems have sticky roots and hanging roots. The leaves have been used as traditional anticancer in Singapore. Indonesian people have also used R. pinnata plants as a diuretic agent, anticancer and antibacterial. R. pinnata plants contain active substances from alkaloid compounds, flavonoids, saponins, tannins and triterpenoids/steroids.
AIM: The purpose of this study was to determine the organic and inorganic content of Rhaphidophora pinnata (L.f.) Schott water extract in the form of fresh leaves, micro simplicia and nano simplicia.
METHOD: The collected R. pinnata leaves are drained and grinded to make micro, and nano Simplicia powder of R. pinnata leaves. The size characterisation of R. pinnata leaves was analysing using Particles Size Analyzer. The water extract of R. pinnata leaves, micro simplicia, and nano simplicia R. pinnata leaves was made 10% (w / v) in water. Phytochemical screening of nano simplicia and nano simplicia water extract included an examination of alkaloid compounds, flavonoids, saponins, tannins, glycosides, and steroids/triterpenoids. Thin-layer chromatography analysis of water extract was analysed using TLC scanner. The element that contains in the water extract was analysed using atomic absorption spectrophotometry methods.
RESULT: The results of phytochemical screening of nano simplicia powder and nano simplicia water extract showed the presence of flavonoids, alkaloids, saponins, tannins, and glycosides. Eluent, which shows good elution is n-butanol: acetic acid: water (6: 2: 2). This eluent is used to elute polar and semipolar compounds and is very good for separating flavonoids. R. pinnata water extract contains the minerals potassium, sodium, magnesium and calcium.
CONCLUSION: R. pinnata water extract contains organic compounds in the form of flavonoids, alkaloids, saponins, tannins, and glycosides. The nano simplicia water extract showed more chemical content than other water extracts on the TLC plate by detection at a wavelength of 250 nm and 300 nm. The most element content in R. pinnata water extract is potassium, followed by magnesium, sodium, and calcium.

Le vouloir dire et la référence selon Fichte
Authors: Marcuzzi Max
Published: January 2020

Dans ses premiers écrits sur l’origine du langage, Fichte affirme de manière circulaire à la fois la caractère premier et constitutif du langage, et le primat de la pensée sur celui-ci. En même temps, il fait du langage à la fois le produit de la liberté et une structure fondamentale de l’homme. Les Discours à la nation allemande présentent une solution à ce cercle en faisant du langage un élément fondamental de l’être au monde de l’homme et de son existence sociale. En soustrayant ainsi le langage à la contingence des décisions individuelles, il en fait la forme naturelle et originelle de la connaissance et de la vérité.
Freud et la bande dessinée : une rencontre onirique
Authors: Marotta Juliette , Bonnet Christian , Gimenez Guy
Published: January 2020

Dans cet article nous souhaitons éclairer les liens d’analogies et d’isomorphismes existant entre la structure du rêve selon Freud et celle de la bande dessinée. En effet, dans « L’interprétation des rêves », Freud n’aura recours qu’à une seule illustration. N’est-ce pas étonnant que ce soit d’une planche de bande dessinée qu’il s’est emparé ? Loin d’être anecdotique, nous envisageons ce choix comme révélateur des liens d’homologie processuels qui régissent le travail du rêve et le travail de la bande dessinée. Pour illustrer cette homologie, nous mettons en rapport la planche de bande dessinée choisie par Freud pour illustrer le travail du rêve avec les productions de McCay, auteur de renom et explorateur de l’activité onirique.

La politique agricole commune (PAC) date de 1962. La situation de l’Europe a beaucoup évolué depuis, comme le montre l’essoufflement de son projet politique. Pourtant l’Europe occupe la première place des exportateurs mondiaux dans un secteur de plus en plus crucial. Il faut donc renforcer une vraie solidarité européenne.
Vivre la foi sous l’horizon de la fin
Authors: Rastoin Marc
Published: January 2020

La gravité de la crise écologique que connaît la planète stimule la créativité des scénaristes et écrivains et amène également essayistes et philosophes à aborder frontalement les questions qu’elle soulève. La perspective d’une fin probable de l’humanité à une échéance plus ou moins proche n’est certes pas nouvelle, mais elle crée un climat anxiogène. Comment espérer encore dans l’avenir de l’humanité ? Quelles sont les ressources chrétiennes pour aborder la conversion de nos modes de vie ?
Les icônes contemporaines de Julia Stankova
Authors: Bœspflug François
Published: January 2020

L’art de l’icône orientale, que l’Occident a découvert dans la seconde moitié du XX e  siècle, est souvent perçu comme un art figé dans le respect de canons intangibles. Mais certains artistes, inscrits dans la tradition orthodoxe, développent leur propre style et renouvellent cet art. C’est le cas de la peintre bulgare Julia Stankova. Le thème de l’hospitalité d’Abraham, qui avait inspiré la célèbre Trinité de Roublev, présent dans toute son œuvre, permet d’illustrer sa liberté inventive et sa fidélité à ce qui est l’essentiel de l’icône, cet « art de la rencontre ».
Le cinéma comme Épiphanie
Authors: Sonnet Jean-Pierre
Published: January 2020

Une vie cachée, le film de Terrence Malick récemment sorti sur les écrans, raconte les dernières années de la vie de Franz Jägerstätter, objecteur de conscience autrichien pendant l’occupation nazie. C’est une ode à la liberté, enracinée dans une profonde spiritualité. La relation entre Franz et Fani Jägerstätter y manifeste combien les choix les plus singuliers peuvent être vécus en dialogue. La beauté du film est de révéler cette vie cachée, tout en en protégeant le mystère.
Prévention des troubles musculo-squelettiques chez les infirmiers d’un hôpital de province au Vietnam
Authors: Minh Khue Pham , Ngoc Quy Kieu , Forrer Armelle , Thanh Hai Nguyen , Reinharz Daniel
Published: January 2020

Objectif : Cette étude avait pour objectif d’étudier la situation des troubles musculo-squelettiques (TMS) chez les infirmiers et le contexte spécifique de la prévention de ces troubles dans les hôpitaux vietnamiens. Méthodes  : L’objectif de l’étude était mixte. Le volet quantitatif visait à étudier la prévalence, les facteurs de risque et les conséquences des TMS ; le volet qualitatif visait, lui, à étudier les facilitateurs et les barrières entourant l’implantation d’un programme préventif de ces troubles dans le milieu hospitalier. Résultats  : La prévalence des TMS au cours des 12 derniers mois est la plus élevée au niveau du bas du dos, du cou et des épaules (40-59 %). Les facteurs associés à ces troubles sont le stress, le fait d’être une femme et l’intensité du travail. Ces troubles ont un impact sur la capacité de travailler et sur la qualité de vie des infirmiers. Une faible reconnaissance de l’importance de la problématique des TMS par les gestionnaires des hôpitaux, ainsi que le manque de ressources humaines ayant une expertise dans le domaine de la prévention des TMS sont des obstacles à la mise en place d’un programme de prévention des TMS dans les hôpitaux vietnamiens. Conclusions  : Les TMS sont un problème de santé au travail chez les infirmiers cliniciens en milieu hospitalier. La lutte contre ces troubles requiert non seulement d’avoir conscience de l’importance du problème dans les instances où sont définies les politiques de santé, mais aussi de disposer d’une expertise dans ce domaine au sein des hôpitaux.

Authors: Leroyer Ariane , Murcia Marie , Chastang Jean-François , Rollin Laétitia , Volkoff Serge , Molinié Anne-Françoise , Niedhammer Isabelle
Published: January 2020

Objectifs : L’objectif principal de cette étude était de décrire la méthodologie de redressement utilisée dans le cadre de l’observatoire « Évolution et relations en santé au travail » (Évrest). Les objectifs secondaires étaient, d’une part, d’apprécier l’ampleur des écarts entre les estimations brutes et pondérées et, d’autre part, de vérifier que le décalage de deux années dans la disponibilité des données de référence utilisées n’impactait pas substantiellement les estimations produites. Méthodes  : L’étude a porté sur les données recueillies en 2013 et 2014 ( n  = 26 227). Le redressement a comporté deux étapes : 1) la prise en compte de la probabilité de participation de chaque salarié ; 2) le calage sur marges pour corriger les éventuelles distorsions de l’échantillon par rapport au champ de l’enquête, les données de référence utilisées provenant des déclarations annuelles de données sociales (DADS) des années 2014 et 2012. L’impact du redressement a été analysé sur les 60 variables du questionnaire par l’étude des écarts entre les pourcentages bruts et pondérés. Résultats  : Au total, 90 % des écarts observés entre estimations brutes et pondérées étaient compris entre – 2,0 % et + 2,0 % avec les DADS 2014, 83 % avec les DADS 2012. L’estimation brute la plus surestimée concernait le travail à temps plein et celle la plus sous-estimée, le contact avec le public. L’impact d’un décalage de deux années des données de référence était faible, quelle que soit la variable étudiée. Conclusion  : Une méthodologie de redressement pour l’observatoire Évrest a été définie et mise en œuvre, permettant d’extrapoler les résultats à l’ensemble des salariés du champ de l’enquête.
Cancer, territoires et discrimination : des zones rurales aux quartiers prioritaires de la ville
Authors: Meidani Anastasia , Alessandrin Arnaud
Published: January 2020

Introduction : L’objectif de cet article est de restituer une enquête portant sur les déterminants sociaux qui influencent l’expérience cancéreuse dans sa pluralité. Il fait ainsi place aux inégalités socio-économiques et ethnoraciales et discute l’entrée territoriale comme marqueur d’inégalités de la santé. Méthodes  : L’article retient le volet qualitatif et français de deux recherches, dont une européenne et de protocole mixte, et prend appui sur 60 entretiens menés auprès des malades et des professionnels impliqués dans leur prise en charge et 100 heures d’observations in situ de consultations de soins. Résultats  : Les résultats se structurent autour de quatre axes. Le premier fait la part belle au principe d’un accès universel aux soins. Le second met l’accent sur les « minorités visibles », plus présentes dans les quartiers prioritaires de la ville que dans les zones rurales, et leur invisibilisation en oncologie. Le troisième axe se focalise sur les interactions soignants/soignés et la notion de « confiance médiatisée par la “bonne réputation” » des établissements et des professionnels. Enfin, le quatrième axe met en perspective les contours genrés de la trajectoire de la maladie et du soutien social. Conclusion  : L’article met en évidence les mécanismes de production d’inégalités sociales de santé en contexte de désertification. Il montre que ces inégalités restent encastrées dans un système de ségrégation territoriale, socio-économique et raciale qui renforce les sentiments de discrimination des patient.e.s atteint.e.s de cancer.
Femmes et accès aux soins en République démocratique du Congo : des barrières liées au genre
Authors: Lambert Hélène , Kahindo Mbeva Jean-Bosco
Published: January 2020

Introduction : L’étude présentée dans cet article cherche à comprendre les barrières rencontrées par les femmes pour accéder aux soins de santé dans la ville de Goma, en République démocratique du Congo. But de l’étude  : Nous avons opté pour une recherche de type qualitatif en utilisant une méthode d’analyse inductive générale. Nous nous sommes penchés sur le vécu, les perceptions et les représentations de la population et des prestataires de soins en conduisant au total 66 entretiens semi-directifs. Nous avons également organisé six focus groups . Au total, 109 personnes ont participé à l’étude. Résultats  : À Goma, le recours aux structures de soins nécessite souvent l’accord préalable du mari ou du chef de famille. Au sein des hôpitaux et des centres de santé, le harcèlement sexuel semble être une pratique fréquente qui peut dissuader certaines femmes ou filles de s’y rendre. Dans la population féminine, les jeunes, les mères célibataires et les femmes victimes de violences sexuelles rencontrent des obstacles spécifiques. Les soignants, loin d’être des techniciens neutres, sont imprégnés des normes culturelles et religieuses dominantes, ce qui retentit sur les prestations délivrées. Conclusions  : En mettant en relation le genre et l’état civil, l’âge, le niveau d’éducation et le profil socio-économique, nous avons pu déterminer les barrières spécifiques que rencontrent certaines catégories de femmes. Les femmes ne sont néanmoins pas les seules à rencontrer des difficultés dans l’accès aux soins. Il serait intéressant de mener des études sur d’autres groupes discriminés afin d’accéder à une compréhension globale de la situation.
Espacialização dos serviços ecossistêmicos na escala local em um contexto de desmatamento: que abordagens estatísticas e quais dados?
Authors: Clec'h Solen Le , Oszwald Johan , Dufour Simon , Desjardins Thierry , Jegou Nicolas , Grimaldi Michel
Published: January 2020

O Millenium Ecosystem Assessment (MEA) e os REDD (Reducing Emissions from Deforestation and Forest Degradation) defendem o desenvolvimento de novas abordagens para quantificar e espacializar os serviços ecossistêmicos (SEs). Essas abordagens podem permitir a implementação de práticas e políticas mais adequadas para a gestão ambiental. A cartografia dos SEs aparece como uma das principais ferramentas para a gestão dos espaços com importantes desafios ambientais. O estudo foi feito em três localidades impactadas pela frente de desmatamento da Amazônia brasileira. Dois processos físicos que fornecem SE, a infiltrabilidade da água no solo e o estoque de carbono na vegetação, foram mapeados com uma resolução espacial de 30x30m. Para isso, medições in situ de biomassa vegetal e de velocidade de infiltração da água no solo dentro de 135 pontos in situ e dados de sensoriamento remoto foram correlacionadas com modelos estatísticos. Esses modelos fornecem uma estimativa desses processos para todos os locais e permitem identificar os fatores que os influenciam. As cartografias resultantes facilitam a compreensão da distribuição espacial desses processos e podem servir de base para a cartografia dos trade-offs e sinergias entre os SEs.

Published: January 2020

Pteridophytes are of minor economic significance to humankind as compared to other groups of plants, especially angiosperms. However, many of them are horticulturally desirable and used for decorations and ornamental purposes and some also as medicines and food. In the present study, the diversity, distribution and conservation perspectives of pteridophytic flora in homegarden ecosystems in the Polgolla Grama Niladhari Division (PGND), Kandy district, Sri Lanka, were investigated. All conceivable habitats of pteridophytes within homegardens and suburb areas in the PGND were visited frequently over a period of one year and representative samples were collected and preserved as herbarium specimens. The species collected were identified using the “Revised Handbook to the Flora of Ceylon” (Vol. XV and XVI) and verified with the specimens deposited at the Herbarium, National Botanic Gardens, Peradeniya, Sri Lanka. The study found 32 species of pteridophytes belonging to 12 families in homegardens and suburbs of three villages in the study area namely Megodagama, Egodagama and Gangewattegama. Although the importance and the conservation measures of pteridophytes have not been understood by the residents, many pteridophytes have been commonly grown as ornamental, crop and medicinal plants in their homegardens. This preliminary survey highlights the species richness of pteridophytes and the importance of conservation of existing species in PGND.
Active Inceptor Failure as a Trigger for Pilot-Induced Oscillations
Authors: Jones Michael , Barnett Miles
Published: January 2020

The use of active inceptor systems allows for control of the aircraft even following mechanical failures within the control inceptor. For the specific case of isometric failure, whereby the inceptor "freezes" in position, a virtual force-displacement model is used to continue to provide
control input. Testing on DLR's experimental helicopter (active control technology/flying helicopter simulator) has shown the potential to encounter pilot-induced oscillation (PIO) tendencies when flying using this mode. This paper presents results from a simulation campaign undertaken to
determine whether PIOs could be exposed through this use of control and/or the resultant severity. The results show that isometric failure caused severe PIOs. Unacceptable failure characteristics were reported by all four pilots. PIO incipience was predicted through the use of offline tools.
It is recommended that specific PIO investigations be undertaken during the evaluation of active inceptor failure modes.

The pronunciation of identical consecutive letters in the Yemenite Jewish tradition
Authors: Zur Uri
Published: January 2020

This article examines the pronunciation of identical consecutive letters in the Yemenite Jewish tradition, with a basic comparison with the pronunciation of identical letters in other present-day traditions. It is notable that in the Yemenite tradition also there are differences of opinion as to the pronunciation of these letters as a result of the effect of their pronunciation in other present-day traditions. In this article, we present the fundamental views with regard to the pronunciation of identical consecutive letters as well as their possible pronunciations in light of the grammar rules evident from the grammarians. The article does not purport to provide a historical, developmental or chronological investigation of the grammar rules; rather, it focuses on one specific topic involving the pronunciation of identical consecutive letters in the Yemenite tradition.
Predictive power of tumour budding for lymph node metastasis in colorectal carcinomas
Authors: Deb Brototo , Jacob Sajini Elizabeth
Published: January 2020

Background & objectives:

Tumour budding is a feature of epithelial-to-mesenchymal transformation that is characterized histologically within the tumour stroma by the presence of isolated cells or clusters of less than five cells which are different from the other malignant cells. This could be present around the invasive margin of the tumour, called peritumoural budding, or in the bulk of the tumour, called intratumoural budding. The aim of this study was to assess the predictive power of tumour budding for lymph node metastasis and its relationship with other features of tumour progression in colorectal carcinoma (CRC).

Methods:

Preoperative colonoscopic biopsies and consecutive resection specimens from 80 patients of colorectal cancer were taken. In the biopsy, intratumoural budding was looked for and graded. In the resection, peritumoural budding was seen and graded along with other features such as grade of the tumour, lymphovascular emboli and tumour border configuration.

Results:

Intratumoural budding was seen in 23 per cent (18/80) and peritumoural in 52 per cent (42/80) of cases. Intratumoural budding was associated with the presence of lymphovascular emboli (P=0.002) and irregular tumour border configuration (P=0.004). Peritumoural budding was also significantly associated with the presence of lymphovascular emboli and irregular margins (P<0.001). Both intra- and peritumoural budding were not associated with the grade of the tumour. Both intra- and peritumoural budding had a significant association with lymph node metastasis (LNM) (P<0.001).

Interpretation & conclusions:

Our findings indicate that tumour budding in preoperative biopsy and resection specimens may predict a possibility of finding LNM in patients with CRC.
Environmental & occupational exposure & female reproductive dysfunction
Authors: Kumar Sunil , Sharma Anupama , Kshetrimayum Chaoba
Published: January 2020

All individuals are exposed to certain chemical, physical, biological, environmental as well as occupational factors. The data pertaining to role of these factors on female reproduction are scanty as compared to male. The available data suggest the adverse effects of certain toxicants, viz., metals such as lead, cadmium and mercury, pesticides such as bis(4-chlorophenyl)-1,1,1-trichloroethane and organic solvent such as benzene, toluene and ionizing radiation on the female reproductive system affecting directly the organ system or impacting in directly through hormonal impairments, molecular alterations, oxidative stress and DNA methylation impairing fertility as well as pregnancy and its outcomes. Thus, there is a need for awareness and prevention programme about the adverse effects of these factors and deterioration of female reproductive health, pregnancy outcome and offspring development as some of these chemicals might affect the developing foetus at very low doses by endocrine disruptive mechanism.

Authors: Pawar Shailesh D. , Keng Sachin S. , Tare Deeksha S. , Thormothe Anil L. , Sapkal Gajanan N. , Anukumar B. , Lole Kavita S. , Mullick Jayati , Mourya Devendra T.
Published: January 2020

Background & objectives:

Avian influenza (AI) viruses have been a major cause of public health concern. Wild migratory birds and contaminated environmental sources such as waterbodies soiled with bird droppings play a significant role in the transmission of AI viruses. The objective of the present study was to develop a sensitive and user-friendly method for the concentration and detection of AI viruses from environmental water sources.

Methods:

Municipal potable water, surface water from reservoirs and sea were spiked with low pathogenic AI viruses. To concentrate the viruses by precipitation, a combination of potassium aluminium sulphate with milk powder was used. Real-time reverse transcription-polymerase chain reaction was performed for virus detection, and the results were compared with a virus concentration method using erythrocytes. Drinking water specimens from poultry markets were also tested for the presence of AI viruses.

Results:

A minimum of 101.0 EID50 (50% egg infectious dose)/ml spiked H5N1 and 101.7 EID50/ml spiked H9N2 viruses were detected from spiked potable water; 101.0 and 102.0 EID50/ml spiked H5N1 virus was detected from surface water and seawater samples, respectively. The present method was more sensitive than the erythrocyte-binding method as approximately 10-fold higher infectious virus titres were obtained. AI H9N2 viruses were detected and isolated from water from local poultry markets, using this method.

Interpretation & conclusions:

Viability and recovery of the spiked viruses were not affected by precipitation. The present method may be suitable for the detection of AI viruses from different environmental water sources and can also be applied during outbreak investigations.
Oral metronomic chemotherapy for recurrent & refractory epithelial ovarian cancer
Authors: Sharma Aparna , Malik Prabhat Singh , Khurana Sachin , Kumar Sunesh , Bhatla Neerja , Ray M.D. , Kumar Lalit
Published: January 2020

Background & objectives:

Advanced epithelial ovarian cancer (EOC) is associated with dismal outcome and progression-free survival (PFS) shortens with each subsequent relapse. For patients with recurrent and platinum refractory disease, therapeutic options are limited. Oral metronomic therapy (OMT) is associated with symptomatic relief and stable response in a significant proportion of patients. We retrospectively evaluated the outcome of patients with EOC treated with OMT at a tertiary care hospital in north India.

Methods:

Between January 2011 to December 2017, 36 EOC patients received OMT. Patients’ median age was 50 yr (range, 38-81 yr) and they had received a median of two lines of prior chemotherapy. OMT regimen included a combination of cyclophosphamide, etoposide (VP-16) and celecoxib with or without pazopanib along with supportive care. Response rates and outcomes were ascertained using the Gynecological Cancer Intergroup Guidelines. The toxicity was graded according to the Common Terminology Criteria for Adverse Events v.4.03.

Results:

The median CA-125 before initiating OMT was 160 U/ml (range, 42.23-5330 U/ml). The median interval between last chemotherapy and starting OMT regimen was 159 days (range, 1-1211 days). The overall response rate was 50 per cent. The median progression-free survival (PFS) was 8.2 months [95% confidence interval (CI): 5.03-10.33], and the median overall survival was 38 months (95% CI: 25.6-NR). Patients who received two lines of chemotherapy before OMT (P=0.052) and those who received pazopanib-based OMT (P=0.0513) had better PFS.

Interpretation & conclusions:

For patients with relapse and refractory EOC, OMT could be a reasonable option. A combination of oral etoposide (VP-16) and pazopanib needs further evaluation in a large number of patients in a randomized trial.

This study dealt with the hydrochemistry of As Suqah area,
NE of Jeddah, Saudi Arabia. The study is based on the analyses of the
major and trace elements of 16 water samples. The groundwater
shows relatively high concentrations in their overall mineral contents
and a high EC, TDS, and total hardness as CaCO3.
Two groundwater types were identified in the As Suqah area:
Na-Mg-Ca-Cl-SO4 and Na-Ca-Mg-Cl water types. Sodium adsorption
ratio has a mean value of 14.39. The exchangeable sodium ratio has a
mean value of 0.456 and a maximum value of 1.706. The average
magnesium hazard was found to be about 49.97. The groundwater in
As Suqah area was slightly supersaturated with respect to calcite and
supersaturated with respect to dolomite. The mean saturation indices
for these species are 1.21 and 2.60 respectively. The main
hydrochemical processes responsible for the above discussed variation
in water quality are recharge, ion-exchange and mineral dissolution.
The water quality within the sedimentary succession was found to be
of relatively higher salinity. Its use is restricted for domestic use only
if adequately treated.
Многомерные модули выпуклости и округлости в банаховых пространствах
Authors: Ramasinghe W
Published: January 2020

Джеремия и Салливен [Ann. Math Pure Appl., 127 (1981), 231-251] дали необходимое и достаточное условие для того, чтобы $\ell^p$-произведение пространств было 2-равномерно округлым. Мы распространяем этот результат на случай $k$-равномерной округлости для любого целого числа $k>1$. Нерефлексивное, равномерно неоктаэдрическое банахово пространство $\widetilde X$, построенное Джеймсом [Israel J. Math., 18 (1974), 145-155], не содержит произвольно точных копий пространства $\ell^{k+1}_1$, хотя и не является $k$-равномерно округлым для любого $k\ge2$. Отсюда видно, что банахово пространство $X$, не являющееся $k$-равномерно округлым, не обязательно содержит произвольно точные копии пространства $\ell^{k+1}_1$ для любого $k\ge2$. Мы показываем, что достаточное условие для того, чтобы банахово пространство $X$ не было $k$-равномерно округлым, состоит в том, что оно содержит произвольно точную копию одной из граней пространства $\ell^{k+1}_1$, а не самого $\ell^{k+1}_1$.
Contextual factors and language: an analysis of order placements from a Japanese crowdsourcing website
Authors: BEKEŠ Andrej
Published: January 2020

Business documents, like other communications, are created in specific social context to achieve various specific social goals. This study examines relationship between the linguistic characteristics of order placements on Japanese dedicated crowdsourcing website and their context of situation, focusing on the power relations between the orderer and the subcontractor. As for the relationship between the orderer and the subcontractor, qualitative analysis of data shows that it is the orderer who is overwhelmingly powerful in this relationship. This imbalance seems to be reflected in the linguistic characteristics of order placements, such as choices made in the system of grammar, and in the quality of information in the sense of Grice’s maxims of conversation.
Clitic or Agreement Restriction in Santali: A Typological Analysis
Authors: DILIP Mayuri J. , KUMAR Rajesh
Published: January 2020

This paper investigates the syntactic configuration of pronominal number marking in Santali. Syntactic, morphological and prosodic restrictions show that pronominal number markers have properties of an affix as well as a clitic. A marker is an affix due to the fact that it cannot participate in a binding relation with other arguments. A pronominal number marker also functions as a clitic since it is attached to prosodically the most prominent constituent. The arguments that trigger object agreement do not manifest one particular case, but instead indicate a dissociation between a case and object agreement. On the other hand, the argument with subject agreement manifests nominative case only, indicating an association between nominative case and subject agreement. Both subject and object agreement are sensitive to case that indicates a property of an affix. Keeping in view the distribution of the pronominal number markers, we analyze feature checking of the two parameters, namely agreement and case in Santali.

“Sharing Beauty With All”: Sustainability According to L’Oréal Italia
Authors: De Caterina Filippo
Published: January 2020

The article highlights the close connection between L’Oréal’s economic success and the fulfilment of its role as a social and environmentally-friendly player. Sustainability has become a strong and constant element in L’Oréal’s identity since the launch of the “Sharing Beauty With All” (SBWA) project. This is a formalised “system” of choices, green policies and socially responsible initiatives resting on four pillars: innovation, production, living and sustainable development.  L’Oréal’s approach to sustainability also involves educating employees, collaborators and consumers in order to disseminate a new way of thinking of products and their consumption: the company aims to increase its cultural footprint, while it endeavours to reduce its environmental one.

En primer lugar, permite mostrar a los estudiantes cómo se puede usar una herramienta computacional para resolver problemas que requerirán una cantidad considerable de trabajo si se resolvieran analíticamente. En segundo lugar, permite presentar un ejemplo de controlador avanzado: el predictor de Smith. En último lugar, empleando este modelo los estudiantes pueden "jugar" con el sistema para estudiar el efecto de los diferentes parámetros del sistema y del controlador sobre el desempeño del sistema controlado.

Abstract. We use the GEOS-Chem chemical transport model to examine the influence of bromine release from blowing snow sea salt aerosol (SSA) on springtime bromine activation and O3 depletion events (ODEs) in the Arctic lower troposphere. We evaluate our simulation against observations of tropospheric BrO vertical column densities (VCDtropo) from the GOME-2 and OMI spaceborne instruments for three years (2007–2009), as well as against surface observations of O3. We conduct a simulation with blowing snow SSA emissions from first-year sea ice (FYI, with a surface snow salinity of 0.1 psu) and multi-year sea ice (MYI, with a surface snow salinity of 0.05 psu), assuming a factor of 5 bromide enrichment of surface snow relative to seawater. This simulation captures the magnitude of observed March–April GOME-2 and OMI VCDtropo to within 17 %, as well as their spatiotemporal variability (r = 0.76-0.85). Many of the large-scale bromine explosions are successfully reproduced, with the exception of events in May, which are absent or systematically underpredicted in the model. If we assume a lower salinity on MYI (0.01 psu) some of the bromine explosions events observed over MYI are not captured, suggesting that blowing snow over MYI is an important source of bromine activation. We find that the modeled atmospheric deposition onto snow-covered sea ice becomes highly enriched in bromide, increasing from enrichment factors of ~ 5 in September–February to 10–60 in May, consistent with freshly fallen snow composition observations. We propose that this progressive enrichment in deposition could enable blowing snow-induced halogen activation to propagate into May and might explain our late-spring underestimate in VCDtropo. We estimate that atmospheric deposition of SSA could increase snow salinity by up to 0.04 psu between February and April, which could be an important source of salinity for surface snow on MYI as well as FYI covered by deep snowpack. Inclusion of halogen release from blowing snow SSA in our simulations decreases monthly mean Arctic surface O3 by 4–8 ppbv (15–30 %) in March and 8–14 ppbv (30–40 %) in April. We reproduce a transport event of depleted O3 Arctic air down to 40º N observed at many sub-Arctic surface sites in early April 2007. While our simulation captures a few ODEs observed at coastal Arctic surface sites, it underestimates the magnitude of other events and entirely misses some events. We suggest that inclusion of direct snowpack activation, which is a strong local source of Br radicals in the shallow Arctic boundary layer, could help reconcile the success of our simulation at capturing satellite retrievals of VCDtropo with its difficulty in reproducing local ODEs.

Abstract. Our understanding of climate and vegetation changes throughout the Holocene is hampered by biases in the proxy representativeness in sedimentary archives. Such potential biases are identified by comparing proxies to modern environments. Consequently, it becomes important to conduct multi-proxy studies and robust calibrations. The taiga-steppes of the Mongolian plateau, ranging from the extremely cold-dry Baikal basin to the Gobi desert, are characterized by low annual precipitation and continental annual air temperature as well as livestock grazing. The characterization of the climate system of this area is crucial for the understanding of Holocene Monsoon Oscillations. This study focuses on the calibration of proxy-climate relationships for pollen and glycerol dialkyl glycerol tetraethers (GDGTs) by comparing large published Eurasian calibrations with a set of 53 new surface samples (moss, soil and surface sediments). We show that: (1) preserved pollen assemblages are clearly imprinted on the extremities of the ecosystem range but mitigated and unclear on the ecotones; (2) for both proxies, inferred relationships depend on the geographical range covered by the calibration database as well as on the sample nature; (3) local calibrations, even those derived to the low range of climate parameters encompassed in the study area, better reconstruct climatic parameters than the global ones by reducing the limits for saturation impact, and (4) a bias in climatic reconstructions is induced by the over-parameterization of the models by addition of artificial correlation. We encourage the application of this surface calibration method to consolidate our understanding of the Holocene climate and environment variations.
A novel non-invasive, non-conductive method for measuring respiration

Published: January 2020

Abstract. We present a novel method for measuring dynamic changes
in respiration parameters due to breathing based on the coupling of two
ultra-high-frequency (UHF) antennae. For evaluation, we built a dynamic 3-D
printed phantom encasing two compartments separated by an elastic diaphragm.
By filling this artificial lung with air the effective permittivity in the
compartment changes, resulting in a significant variation of the S21
parameter's magnitude and phase. We show that there is a strong linear
correlation between the volume of air in the artificial lung and the
magnitude (in dB) of the S21 parameter (R2=0.997) as well as
the parameter's phase (R2=0.975). Our sensor system shows a high
reproducibility (standard deviation of predicted volume =0.67 mL) and a
timing similar to a conventional flow sensor (delay =5.33 ms). The
presented method is a promising candidate to overcome some of the most
important technical burdens of measuring respiratory parameters and might be
used as a trigger for patient–ventilator synchronization in infants and
neonates.

Abstract. The existence of debris flows not only destroys the facilities, but also seriously threatens human lives, especially in scenic areas. Therefore, the classification and susceptibility analysis of debris flow are particularly important. In this paper, 21 debris flow catchments located in Huangsongyu town ship, Pinggu District of Beijing, China were investigated. Besides field investigation, geographic information system, global positioning system and remote sensing technology were applied to determine the characteristics of debris flows. This article introduced clustering validity index to determine the clustering number, and the fuzzy C-means algorithm and factor analysis method were combined to classify 21 debris flow catchments in the study area. The results were divided into four types: scale-topography-human activity closely related, topography-human activity-matter source closely related, scale-matter source-geology closely related and topography-scale-matter source-human activity closely related debris flow. And 9 major factors screened from the classification result were selected for susceptibility analysis, using both the efficacy coefficient method and the combination weighting. Susceptibility results showed that the susceptibility of 2 debris flows catchments were high, 6 were moderate, and 13 were low. The assessment results were consistent with the field investigation. Finally, a comprehensive assessment including classification and susceptibility evaluation of debris flow was obtained, which was useful for risk mitigation and land use planning in the study area, and provided reference for the research on related issues in other areas.
Observation and explanation of spurious seismic signals emerging in teleseismic noise correlations
Authors: Li Lei , Boué Pierre , Campillo Michel
Published: January 2020

Abstract. Deep body waves have been reconstructed from seismic
noise correlations in recent studies. The authors note their great
potential for deep-Earth imaging. In addition to the expected physical
seismic phases, some spurious arrivals having no correspondence in
earthquake seismograms are observed from the noise correlations. The origins
of the noise-derived body waves have not been well understood.
Traditionally, the reconstruction of seismic phases from inter-receiver
noise correlations is attributed to the interference between waves from
noise sources in the stationary-phase regions. The interfering waves
emanating from a stationary-phase location have a common ray path from the
source to the first receiver. The correlation operator cancels the common
path and extracts a signal corresponding to the inter-receiver ray path. In
this study, with seismic noise records from two networks at teleseismic
distance, we show that noise-derived spurious seismic signals without
correspondence in real seismograms can arise from the interference between
waves without a common ray path or common slowness. These noise-derived
signals cannot be explained by traditional stationary-phase arguments.
Numerical experiments reproduce the observed spurious signals. These signals
still emerge for uniformly distributed noise sources, and thus are not
caused by localized sources. We interpret the presence of the spurious
signals with a less restrictive condition of quasi-stationary phase:
providing the time delays between interfering waves from spatially
distributed noise sources are close enough, the stack of correlation
functions over the distributed sources can still be constructive as an
effect of finite frequencies, and thereby noise-derived signals emerge from
the source averaging.
