Published: June 2020

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 (second Global Ozone Monitoring Experiment)
and Ozone Monitoring Instrument (OMI) spaceborne instruments for 3 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 composition observations of freshly fallen snow. 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 the 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 40∘ N
observed at many sub-Arctic surface sites in early April 2007. While our
simulation captures 25 %–40 % of the ODEs observed at coastal Arctic surface
sites, it underestimates the magnitude of many of these events and entirely
misses 60 %–75 % of ODEs. This difficulty in reproducing observed surface
ODEs could be related to the coarse horizontal resolution of the model, the
known biases in simulating Arctic boundary layer exchange processes, the
lack of detailed chlorine chemistry, and/or the fact that we did not include
direct halogen activation by snowpack chemistry.
Innovación pública: una propuesta de análisis de los factores que inciden en los procesos de innovación en el sector público local
Authors: Mairal Medina Pilar 
Published: June 2020

La innovación pública es un objeto de investigación emergente que ofrece distintos enfoques para analizar el cambio en las organizaciones del sector público. El ámbito local ha demostrado sus capacidades creativas en este sentido cada vez son más las experiencias de interés relacionadas con el diseño de políticas públicas, el establecimiento de retos y prioridades políticas, y la mejora de los servicios públicos. Sin embargo, y pese a la emergente aparición de espacios no estatales ligados a experiencias innovadoras de participación social, generalmente las administraciones públicas identifican las innovaciones con la integración tecnológica y la transformación cultural de estas organizaciones parece no identificarse con los procesos de innovación.
El artículo resume los principales factores identificados en un estudio empírico que delimitan la percepción de los procesos de innovación pública local y sus resultados, delimitando los condicionantes de estos procesos y los retos que plantean en las organizaciones públicas.
Fronting in Old Spanish
Authors: Batllori Montserrat , Sitaridou Ioanna 
Published: June 2020

The article focuses on a cross-genre study of fronting phenomena in 13th Century Old Spanish. In particular, we study stage topics and deictic fronting, fronting in quotative inversion, quantifier fronting and information/broad/weak focus fronting comparatively, for the first time, in three types of texts (that is, (a) Cantar de Mío Cid, (b) La Fazienda de Ultra Mar, and (c) Estoria de España and General Estoria) while we compare with equivalent judgements from Modern Spanish in order to establish what exactly has changed. “Fronting” a term which has been used to describe all sorts of configurations ranging from stylistic fronting to focus fronting to non-focus fronting receives here a principled discussion. We show that, overall, fronting with a verum focus interpretation has largely been preserved into Modern Spanish, albeit often restricted, while the most notable change seems to be the loss of a preverbal focus position conveying broad focus. In doing so, we reconcile Leonetti’s (2017) claims for an informational partition, which does not divide the fronted element from the verb, but, rather, the fronted element together with the verb from the postverbal subject with our own claims about the syntactic mechanisms which yield this partition. We proceed to conclude that fronting operations are not a derivative of the V2 parameter being operative (contra Wolfe 2015).
Re-Os PYRITE GEOCHRONOLOGY OF THE YELLOWHEAD-TYPE MINERALIZATION, PEND OREILLE MINE, KOOTENAY ARC, METALINE DISTRICT, WASHINGTON
Authors: Paradis Suzanne , Hnatyshin Danny , Simandl George J. , Creaser Robert A. 
Published: June 2020

Abstract
Pend Oreille, a carbonate-hosted Zn-Pb sulfide deposit, is the only base metal mine recently in production within the historically prolific Kootenay arc belt. The deposit consists of two spatially and lithologically distinct types of stratabound, carbonate-hosted Zn-Pb mineralization: Josephine and Yellowhead. The Yellowhead-type sulfide mineralization, the focus of this study, consists of en échelon tabular to lensoidal pyrite-sphalerite–rich orebodies hosted by the middle Cambrian to Early Ordovician Metaline Formation. The Yellowhead-type mineralization is characterized by carbonate replacement and open-space filling textures, indicating diagenetic and epigenetic origin. As with most low-temperature deposits not directly associated with igneous activity, the timing of sulfide mineralization has traditionally been difficult to constrain using radiometric methods.
In this study, we present a new Re-Os age of 512 ± 17 Ma from the Yellowhead mineralization. Combining this age date with the Cambrian-Ordovician fossil record of the host Metaline Formation and detailed textural analysis of the mineralization, we conclude that the Yellowhead sulfide mineralization is largely diagenetic in origin. Such an origin for the Yellowhead mineralization is similar to that of Irish-type deposits worldwide. For explorationists, the presence of Irish-type deposits in the United States portion of the Kootenay arc opens the possibility of discovering similar mineralization in the Canadian extension of the Kootenay arc.
Dermoscopic and confocal features of an axillary “special site” nevus
Authors: Dutt Riana , Rabinovitz Harold S. , Singh Rajendra , Scope Alon 
Published: June 2020

“Nevi of special sites” is a term that denotes melanocytic nevi presenting in specific anatomic locations including the scalp, genital area, flexural sites, and acral sites [1]. Nevi from these anatomic sites display at times histopathologic features that may lead the reading pathologist to recommend re-excision of these benign nevi. Reflectance confocal microscopy (RCM) is a noninvasive imaging tool that allows for visualization of epidermal, dermal-epidermal junctional (DEJ), and superficial dermal tissue structures at cellular level resolution. RCM features of special site nevi have not been previously described in the literature. Defining the RCM characteristics of special site nevi may increase diagnostic accuracy and assist in ruling out melanoma.
Here, we report a case of a pigmented lesion appearing in the axilla of a patient with a recently diagnosed melanoma. Dermoscopic and histopathologic results were consistent with the diagnosis of nevus in flexural anatomic sites. In this case, RCM showed a regular honeycomb pattern of epidermal keratinocytes and enlarged, non-homogenous, discohesive nests at the DEJ, a pattern that corresponded well with the histopathologic findings. Larger studies are needed to establish RCM features of special site nevi in order to reliably rule out melanoma and lower the rate of unnecessary excisions of these benign nevi.
Nails: The Window to the Nose? Update on Yellow Nail Syndrome
Authors: Vollono Laura , Chessa Marco Adriano , Bruno Antonio , Starace Michela , Alessandrini Aurora , Piraccini Bianca Maria 
Published: June 2020

Background: Yellow nail syndrome is a rare condition characterized by typical nail alterations and variable presence of lymphedema and respiratory disease. The pathogenesis is still obscure, with most of the literature deriving from case reports and few investigations. The most reported respiratory conditions associated with yellow nail syndrome are pleural effusion and bronchiectasis, whereas association with rhinosinusitis is rarer.
Objectives: To describe a case of yellow nail syndrome and to provide a literature review regarding this condition, discussing pathogenetic hypothesis, associated conditions, and therapeutic options.
Patients/Methods: A 49-year-old man presented with arrested growth and alterations of his nails, without any history of previous trauma or inflammation but with a severe nasal septum deviation and a history of chronic rhinosinusitis. A diagnosis of yellow nail syndrome was made.
Results: Six months after undergoing rhinoseptoplasty and treatment with oral vitamin E, the patient’s nails were cured.
Conclusions: This case emphasizes the role of the dermatologist in detecting systemic conditions. The correct diagnosis led to complete resolution of both nail alterations and associated respiratory condition.

Published: June 2020

Taxonomic work on the land snail genus Sarika Godwin-Austen, 1907 in Cambodia is scarce. A total of three species were recognized from Cambodia prior to this study. However, their taxonomic descriptions were based mainly on shell morphology, with limited genital data. To address this knowledge gap, we opportunistically surveyed for land snails in Cambodia. Our inventory yielded four species of Sarika – one recognized species, Sarika bocourti (Morelet, 1875), from Battambang Province and three new species, Sarika khmeriana Pholyotha & Panha sp. nov., Sarika lactoconcha Pholyotha & Panha sp. nov. and Sarika nana Pholyotha & Panha sp. nov. from Kampot and Takeo Provinces in southern Cambodia. Our discovery involves the first species of Sarika to be described from Cambodia in more than a century highlights the extent to which the diversity of Cambodian land snails remains to be discovered. The status of two species, Sarika benoiti (Crosse & Fischer, 1863) and Sarika resplendens (Philippi, 1846), is at present ambiguous because no material identifiable as these species was found in recent extensive surveys. Although S. bocourti was recently collected from Cambodia, its taxonomic position remained unclear due to a lack of living specimens. Detailed descriptions and illustrations of living animals, shell morphology and reproductive anatomy are provided, and a map showing their distributions is given.
Com "os nossos ancestrais”: luta e gramática no reconhecimento de lugar de remanescentes humanos no Rio de Janeiro.

Published: June 2020

Com a revitalização urbana na região portuária da cidade do Rio de Janeiro como parte do Projeto Porto Maravilha, iniciado em 2011, ocorreu a descoberta de sinais de um antigo cemitério de escravizados. Diante disso, organizações do movimento negro passaram a atuar para a preservação do local e também para que houvesse homenagem aos antepassados no espaço público. A partir de pesquisa qualitativa, uso de documentos e vídeos, contemplo como foi tornado corrente o uso de categorias relacionadas à investigação da verdade e promoção de reparação, para discutir a escravidão e o tráfico transatlântico. Além disso, cerimônias religiosas foram realizadas, a fim de reconhecer a energia do lugar e a força dos ancestrais, contribuindo para a composição local do debate acerca das tragédias e dores históricas.

Os camarões de água doce do gênero Macrobrachium (Spence Bate, 1868) encontram-se amplamente distribuídos nas Américas e, numericamente este é o gênero dominante da família Palaemonidae. O Estado do Maranhão não dispõe de trabalhos voltados para crustáceos de água doce, sendo este o primeiro estudo realizado com o objetivo de apresentar informações taxonômicas das espécies registradas, com mapa de ocorrência geográfica, características biológicas e ecológicas, uma chave de identificação do gênero Macrobrachium para o Estado, bem como aspectos de conservação. Para isso, oito riachos do Leste do Maranhão, foram amostrados com puçás, peneiras e rede de arrasto, passados no fundo e na vegetação marginal submersa por um período de 20 minutos em um trecho de 150m. Em laboratório, os espécimes foram identificados, mensurados e sexados. Um total de 526 espécimes foram coletados, distribuídos em cinco espécies, sendo: M. carcinus (N=01), M. olfersii (N=55), M. acanthurus (N=116), M. amazonicum (N=119) e M. jelskii (N=235). Somente em M. acanthurus e M. jelskii foram registradas fêmeas ovígeras, M. jelskii apresentou fecundidades de 1 a 65 ovos, ao passo que para a única fêmea ovígera de M. acanthurus foram contados 662 ovos. Também foi elaborado uma chave de identificação do gênero Macrobrachium para o Maranhão. Assim, confirmou-se os registros destas espécies para o Estado e ampliação da área de distribuição, com mapas de ocorrência.
L’UDC en action ou comment le populisme de droite radicale est mobilisé en Suisse au-delà des campagnes électorales1
Authors: Biard Benjamin 
Published: June 2020

Les études sur les partis populistes foisonnent dans la littérature en science politique. Néanmoins, beaucoup d’incertitude caractérise la notion et plusieurs aspects du populisme demeurent inexplorés. Ainsi, si une définition minimale de la notion permet aujourd’hui de faciliter la classification des partis, c’est souvent sur la base des programmes et des discours que ces partis prononcent lors de campagnes électorales que cette classification est effectuée. Or, les partis populistes accèdent de plus en plus aux arènes décisionnelles et il est reconnu qu’ils tendent à adapter leurs stratégies ou leur style politique pour s’y maintenir. Il devient dès lors important de questionner le rôle qu’exercent ces partis lorsqu’ils sont au pouvoir. Parce que peu de travaux ont abordé ce cas et parce qu’il est le parti populiste entretenant le rapport le plus durable et stable avec les pouvoirs exécutif et législatif en Europe, c’est sur l’Union démocratique du centre (UDC) que cette contribution se focalise. À travers une analyse thématique reposant sur des données originales, l’article répond à la question suivante : quel rapport l’UDC en action entretient-elle avec le populisme de droite radicale quand elle est au pouvoir ? L’article interroge le caractère populiste de droite radicale de l’UDC au-delà des périodes de campagne électorale.
L’Internet et les médias sociaux : un effet sur les attitudes des millénariaux canadiens à l’égard de la politique1
Authors: Duguay Philippe A. 
Published: June 2020

Cette étude explore la relation entre certains comportements en ligne des millénariaux canadiens et leurs attitudes à l’égard de la politique. Nous utilisons les données longitudinales de l’Étude canadienne de la jeunesse (ECJ), un sondage en deux vagues à huit ans d’intervalle (n = 967), et proposons des modèles pour étudier l’influence des comportements en ligne sur trois attitudes générales à l’égard de la politique. L’analyse des résultats suggère que la communication interpersonnelle et la recherche d’information en ligne augmentent l’intérêt politique. La recherche d’information politique en ligne augmente également le sentiment que le gouvernement fait quelque chose pour les personnes comme nous. Toutefois, la confiance envers le gouvernement est négativement associée à la participation à des discussions politiques en ligne et positivement associée aux activités de réseautage en ligne.
A Pilot Randomized Controlled Trial to Assess Feasibility and Treatment Effect of a Web-Based Delivered Cognitive Behavioral Therapy for Insomnia Program in Individuals with Multiple Sclerosis
Authors: Siengsukon Catherine F. , Beck Eber Silveira , Drerup Michelle 
Published: June 2020

Abstract
Background: At least 40% of individuals with multiple sclerosis (MS) experience chronic insomnia. Recent studies indicate that cognitive behavioral therapy for insomnia (CBT-I) is an effective treatment for insomnia symptoms in individuals with MS. CBT-I delivered using web-based applications has been shown to be effective and may increase access to CBT-I for individuals with MS who have mobility difficulties, fatigue, or live in rural areas. Therefore, the purpose of this study was to assess the feasibility and treatment effect of CBT-I delivered using a web-based application with or without biweekly phone calls to improve sleep quality and fatigue in individuals with MS and symptoms of insomnia.
Methods: Forty-one individuals with MS and symptoms of insomnia were randomized into either a group that participated in a 6-week web-based CBT-I program (wCBT-I) or a group that participated in a web-based CBT-I program and received biweekly support phone calls (wCBT-I+PC). Participants completed surveys online to assess insomnia severity, sleep quality, fatigue, sleep self-efficacy, depression, anxiety, and motivation to change their sleep behavior.
Results: The overall retention rate was 48.8%, and the adherence rate was 96.34%. Both groups had a significant improvement in insomnia severity, sleep quality, anxiety, and sleep self-efficacy. Only the wCBT-I group had a significant improvement in depression and fatigue.
Conclusions: Web-delivered CBT-I is feasible and effective in improving sleep outcomes and concomitant symptoms in individuals with MS. Web-based CBT-I may increase the accessibility of CBT-I treatment and provide a stepped-care approach to treating chronic insomnia in individuals with MS.

Published: June 2020

Laser irradiation has biostimulating effect in various cell types low power laser radiation is used clinically for skin and vascular disorders.
Aims: To investigate the effect of (He-Ne) laser (λ= 632nm, power=1mW) on human whole blood, after irradiated to different times from 10 min to 50 min.
Study Design: Human Whole Blood Irradiated to (He-Ne) laser(λ= 632nm, power=1mW).
Place and Duration of Study: Soba Hospital, Khartoum- Sudan, Institute of Laser, Sudan University of science and technology (SUST), February 2018.
Methodology: Blood samples were taken from healthy volunteers; blood sample irradiated to (He-Ne) laser and control compared; FTIR and UV-Vis spectrophotometer were used to study laser radiation effect
Results: FTIR spectra and UV-vis absorption spectra of blood samples are compared before and after irradiated to He-Ne laser shows increases absorption for 10, and 40 min but it decreases as the exposure time at 30,20 and 50 minutes. This fluctuation of light absorption is known as a biphasic response.
FTIR spectra of non exposed blood showed the peaks due to O-H (free group), C=O (amide I group), N=O (nitro group), and C-H (aromatic group). N-H (Amino acid (amide II). For all exposure time He-Ne laser (λ= 632nm, power=1mW) irradiation, showed significant changes. Increased in transmittance at different exposure time for all groups (C=O, O-H, N=O, C-O & C-H, N-H) and indicates significant decreasing in their concentration.
Conclusion: The laser radiation causes changes in the structure and conformational changes in the polypeptide and absorption of blood samples decreased due to increasing ligand electronegativity.
Theoretical Verification of Formula for Charge Function in Time q = c * v in RC Circuit for Charging/Discharging of Fractional & Ideal Capacitor
Authors: Das Shantanu 
Published: June 2020

Objective of this paper is verification of newly developed formula of charge storage in capacitor as q = c*v, in RC circuit, to get validation for ideal loss less capacitor as well as fractional order capacitors for charging and discharging cases. This new formula is different to usual and conventional way of writing capacitance multiplied by voltage to get charge stored in a capacitor i.e. q = cv. We use this new formulation i.e. q = c*v in RC circuits to verify the results that are obtained via classical circuit theory, for a case of classical loss less capacitor as well as fractional capacitor. The use of this formulation is suited for super-capacitors, as they show fractional order in their behavior. This new formula is used to get the ‘memory effect’ that is observed in self-discharging phenomena of super-capacitors-that memorizes its history of charging profile. Special emphasis is given to detailed derivational steps in order to clarity in usage of this new formula in the RC circuit examples. This paper validates the new formula of charge storage in capacitor i.e. q = c*v.
