Authors: Ellouze Sami , Lafortune Jean , Soares André
Published: September 2018

Introduction : Les modalités de prise de rendez-vous (RDV) pour une consultation de médecine générale sont un maillon important de la chaîne d’accès aux soins. Notre objectif était de rechercher les facteurs sociodémographiques associés à la prise de RDV sur plateformes internet des patients ayant pris un RDV chez un généraliste parisien. Méthodes : Une enquête épidémiologique transversale multicentrique a été réalisée de janvier à avril 2017 dans 61 pharmacies auprès de patients ayant consulté un généraliste, au sein d’arrondissements parisiens à fort gradient social. Un questionnaire était proposé par les pharmaciens, visant à définir les caractéristiques sociodémographiques des patients ainsi que le mode de rendez-vous pris chez le généraliste. Une analyse univariée et un modèle multivarié ont été utilisés pour déterminer les facteurs associés à la prise de RDV sur plateformes Internet. Résultats : Au total, 423 patients ont été inclus dans l’étude. L’analyse multivariée a indiqué que la catégorie d’âge supérieure à 40 ans (âge 40-59 ans : OR ajusté = 0,46, IC95 % = [0,236 ; 0,879], p = 0,02 et âge supérieur à 60 ans : OR ajusté = 0,023, IC95 % = [0,109 ; 0,49], p = 0,0001), la non-utilisation d’internet (OR ajusté = 10,55 [3,62 ; 45,04], p = 0,0001) et l’habitation dans des quartiers parisiens définis sur le seul critère de pauvreté (OR ajusté = 0,427, IC95 % = [0,23 ; 0,76], p = 0,004]) étaient fortement associés de manière défavorable à la prise de RDV via une plateforme internet chez le généraliste. Conclusions : L’utilisation des plateformes de prise de RDV en ligne doit être couplée aux moyens organisationnels usuels (consultation libre et prise de RDV téléphonique) afin de proposer un accès aux soins égalitaire à tous.
Collaboration interprofessionnelle pour la santé buccodentaire des personnes âgées – esquisse de mise en œuvre
Authors: Harnagea Hermina
Published: September 2018

Le vieillissement accéléré de la population entraîne une augmentation du nombre de personnes en perte d’autonomie. Même chez les personnes âgées en bonne santé, les déficits d’auto-soins sont liés à la diminution de la mobilité, de l’endurance et à la perte sensorielle. Dans les centres d’hébergement, les résidents dépendent des soignants pour la majorité des activités de la vie quotidienne. En général, l’offre de service dentaire pour les personnes en perte d’autonomie demeure insuffisante. Plusieurs facteurs peuvent expliquer cette situation dont l’absence de directives gouvernementales et le manque de formation initiale et continue du personnel autant dentaire que non dentaire. Issues d’une revue des publications parues entre 1970-2016, quatre stratégies se démarquent : valoriser, soutenir et formaliser la collaboration interprofessionnelle, bâtir une vision commune autour de la santé buccodentaire, développer des compétences professionnelles et relationnelles complémentaires et partagées, redéfinir les rôles et responsabilités des intervenants en soins primaires. Ces stratégies pourraient être considérées dans le processus de mise en œuvre d’une offre de services buccodentaires adapté aux besoins de ce groupe de population.

Published: September 2018

Introduction : La non-divulgation du statut sérologique par une femme enceinte à son entourage, et tout particulièrement au père de l’enfant à naître, peut représenter un obstacle à la prévention de la transmission du VIH de la mère à l’enfant. C’est dans ce contexte que notre étude se propose de déterminer la proportion des femmes n’ayant pas divulgué leur séropositivité au VIH à leur conjoint et les facteurs associés à cette non-divulgation. Patients et méthodes : Il s’agissait d’une étude transversale, descriptive et analytique allant du 1 er  février au 30 mai 2017. La population d’étude était constituée de toutes les femmes enceintes ou non enceintes VIH positives, suivies dans l’un des trois principaux services de santé maternelle et infantile de Bangui. Résultats : Au total, 256 femmes ont été recrutées. Parmi elles, 76 femmes n’ont pas divulgué leur séropositivité au VIH à leur conjoint, soit une proportion 29,7 %. Les principaux facteurs associés à la non-divulgation de la séropositivité étaient le jeune âge du conjoint, sa situation professionnelle précaire et les couples qui vivaient séparément. Conclusion : À la lumière des résultats obtenus dans notre étude, des efforts doivent être faits pour impliquer davantage les partenaires dans les programmes de santé sexuelle et reproductive en général et de la prévention de la transmission de la mère à l’enfant en particulier. Également, la population doit être sensibilisée sur les dangers de la stigmatisation et la loi relative à la protection des personnes vivant avec le VIH doit être appliquée.

Published: September 2018

Introduction : Cette étude vise à évaluer le système de surveillance des manifestations adverses post-immunisations (MAPI) dans les districts sanitaires de la ville d’Abidjan. Méthodes : Notre étude a porté sur les activités menées entre le 1 er  janvier et 31 décembre 2015 inclus. Il s’agit d’une étude transversale évaluative qui a concerné les neuf districts sanitaires d’Abidjan. Les données ont été collectées au moyen d’un questionnaire conçu sur le modèle des fiches d’évaluation de l’Organisation Mondiale de la Santé. Ces questionnaires ont été administrés au personnel en charge de la surveillance épidémiologique au niveau des districts sanitaires et à ceux des hôpitaux de district et des centres de santé. Résultats : Le système de surveillance des MAPI, au-delà de sa simplicité et de sa flexibilité est un système peu performant car son acceptabilité par tous les acteurs reste relativement faible. En effet, au niveau des enquêtés, seulement 4 % du personnel de santé participe à cette activité ; 55 % des districts sanitaires ont notifié des cas de MAPI et 25 % des formations sanitaires ont déclaré des cas ; toute chose qui rend ce système peu sensible et peu utile à la prise de décisions dans le cadre de la politique sanitaire de la réduction de ces accidents. Conclusion : L’amélioration de la performance du système de la surveillance des MAPI passe par une meilleure formation du personnel de santé et sa dotation en outils informatiques ainsi qu’une amélioration de la participation communautaire.

In our previous study we confirmed an antiviral activity of probiotic Lactobacillus reuteri L26 which was mediated by stimulation of local intestinal immunity. The aim of this paper was to evaluate the influence of L. reuteri L26 on the systemic immune response in gnotobiotic mice infected with porcine circovirus type 2 (PCV2). A total of 30 germ-free mice were divided into 3 groups and animals in noninfected and infected control groups (NC and IC; n=10) received sterile de Man-Rogosa-Sharpe broth for 7 days and animals in experimental group L+PCV (n=10) were inoculated with L. reuteri L26. Subsequently, mice in L+PCV and IC groups were infected with PCV2; however, mice in the control group received virus cultivation medium (mock). The results showed an increase of percentage of cytotoxic cells (CD8+ and CD49b+CD8-) and oxidative burst of phagocytes, up-regulation of the gene expression of RANTES, granulocyte-macrophage colony-stimulating factor, interferon-γ and immunoglobulin A in blood above all in the later phase of infection (14 dpi) in L+PCV group accompanied by higher load of PCV2 in the serum. These findings indicate that L. reuteri L26 has a potential to induce systemic immune reaction, but in gnotobiotic mice immune stimulation can increase virus replication.
Palygorskite in caves and karsts: a review
Authors: Bosák Pavel , Zupan Hajna Nadja
Published: September 2018

Palygorskite is fibrous mineral representing the transitional phase between chain silicates and layer silicates with modulated phyllosilicate structure. Although often found in carbonate environments, it forms quite uncommon constituent of cave fills. Palygorskite occurs in cave fills in two forms: (1) allogenic palygorskite which in arid and semiarid conditions can represents substantial constituent of cave fills, often associated with smectite, gypsum, calcite and halite; it is airborne or transported by surface run-off to caves from desert soils and paleosoils, calcretes, dolocretes and related deposits in cave surroundings. (2) Authigenic palygorskite occurs as in situ precipitate in cave fills from percolating water solutions and/or transformation of smectite and kaolinite in dry evaporative conditions and suitable geochemical composition of solutions. In carbonate host-rocks palygorskite fills fissures and faults and often it is found in cave walls. It occurs commonly as part of the “mountain leather” as a result of hydrothermal and/or weathering processes or represents a product of in situ chemical precipitation from percolating meteoric solutions with suitable pH a redox conditions and chemical composition.Key words: palygorskite, caves, karst.Paligorskit v jamah in krasu: pregledPaligorskit je vlaknat mineral, ki je prehodna fazo med inosilikati in listastimi silikati z modulirano strukturo filosilikata. Čeprav je pogost v karbonatnih okoljih, je precej neobičajna sestavina jamskih sedimentov. Paligorskit se v jamah pojavlja v dveh oblikah: (1) kot alogeni paligorskit, ki je v sušnih in polsuhih razmerah lahko znaten sestavni del jamskih sedimentov, pogosto povezanih z montmorillonitom, sadro, kalcitom in halitom; v teh primerih gre za eolski nanos ali pa za transport v jame s površinskim transportom iz puščavskih tal in paleotal, kalkret, dolokret in podobnih sedimentov; (2) kot avtogeni paligorskit se pojavlja v jamah kot »in situ« oborina iz prenikajočih raztopin in/ali z obarjanjem med transformacijo montmorillonita in kaolinita v jamskih sedimentih v suhih razmerah izhlapevanja in primerno geokemično sestavo raztopin. V karbonatnih kamninah paligorskit zapolnjujejo razpoke in prelome in ga pogosto najdemo na jamskih stenah. Običajno se pojavlja kot del “gorskega usnja”, ki je posledica hidrotermalnih in/ali procesov preperevanja. Lahko pa nastane tudi zaradi in situ kemičnega obarjanja iz prenikajočih meteornih raztopin z ustreznim pH, redoks potencialom in kemično sestavo.Ključne besede: paligorskit, jame, kras.
Descrédito de la verdad y banalización de la ideología
Authors: Giner De San Julián Salvador
Published: September 2018

La sociología del conocimiento, y dentro de ella la de la ideología, se basan en una sólida tradición y han progresado a través del tiempo. No obstante, la expansión del relativismo en la ciencia social, por una parte, y de una simplista visión determinista, por otra, ha hecho mella en esta tradición. El presente ensayo reivindica los fueros del análisis clásico de la ideología, demuestra su valía para la sociología cognitiva (o cognoscitiva) y pone de relieve las falacias y pobreza de las posiciones llamadas posmodemas, que son las que encaman más claramente los males que aquejan un estudio fértil y riguroso de las condiciones sociales del conocimiento objetivo.
La categoría social de voluntariado y su realidad en España
Authors: Fernandez Prados Juan Sebastian
Published: September 2018

Los dos principales objetivos tratados en este estudio son, por una parte, construir un modelo conceptual de la categoría social de voluntariado y, por otra, cuantificar la realidad del voluntariado en España. Para ambos fines, se hace un repaso a la bibliografía sobre definiciones e investigaciones que hayan tenido como tema las entidades de voluntarios. Finalmente, el presente trabajo concluye, en primer lugar, la necesidad de aplicar criterios más rigurosos a la hora de medir el voluntariado en España desde un concepto bien delimitado y, en segundo lugar, el escaso peso que tiene el voluntariado en la sociedad española actual, a pesar del aumento de las organizaciones del Tercer Sector.

La construcción de la identidad pública del movimiento antiglobalización en España
Authors: Jiménez Sánchez Manuel , Alcalde Villacampa Javier
Published: September 2018

Desde Seattle, la atención prestada por los medios de comunicación al movimiento antiglobalización ha estado vinculada a la cuestión de la violencia. Su mayor presencia mediática ha impulsado su consolidación como movimiento global. También ha elevado el coste político de la represión física de las acciones no-violentas y ha fomentado un cambio gradual en la respuesta de las autoridades. En este sentido, el espacio central de confrontación parece haberse desplazado (o extendido) desde las calles al terreno de lo simbólico, para localizarse en el proceso de configuración de la imagen (o identidad) pública del movimiento a través del discurso en los medios. Este trabajo indaga en la naturaleza de este proceso mediante el análisis de los discursos recogidos en las noticias publicadas en El País durante la presidencia española de la UE en el año 2002.
Kent Monkman : entre ré/appropriation et « Painting Back ».
Authors: Pancaldi Valentina
Published: September 2018

À la suite d’une série d’évènements historiques de grande relevance sociopolitique, les années 1990 ont connu une montée d'initiatives menées par les artistes autochtones nord-américains visant à une récupération et une divulgation de leur l’héritage culturel, et, de ce fait, à une revendication de leur visibilité dans le panorama international. De cette résurgence, l’artiste multimédial autochtone canadien, Kent Monkman, constitue l’une des voix plus actives et plus emblématiques. En créant un dialogue épistémologique entre les études postcoloniales et l’art autochtone, cet article interrogera l’œuvre de Kent Monkman au prisme d’une notion dont sera proposée une définition, à savoir le « Painting Back ».
Analyzing the Acquisition and Management of Context
Authors: Rivero-Rodriguez Alejandro , Nykänen Ossi , Piché Robert
Published: September 2018

Mobile users want mobile services tailored to their current context and needs. These context-aware services have primarily focused on position information; using other types of user information would enhance the development of smarter services. There is a range of frameworks that manage and distribute user context; however, when several information sources and inference techniques are available, these context frameworks face the need to make appropriate decisions to facilitate the most suitable context information to applications. This article describes strategies to solve a context acquisition problem, namely the choice of the information channel, given available user information and context obtaining services. The proposed context acquisition strategy, based on Bayesian decision theory, improves the frameworks' decision making and enables integrating and encapsulating a wide set of context inference and reasoning algorithms and data sources, in a well-documented, transparent, and principled way.

Intravenous Drug Delivery System for Blood Pressure Patient Based on Adaptive Parameter Estimation
Authors: Singh Bharat , Urooj Shabana
Published: September 2018

Controlled drug delivery systems (DDS's) is an electromechanical system that supports the injection of a therapeutic drug intravenously into a patient's body and easily controls the infusion rate of patient's drug, blood pressure, and time of drug release. The controlled operation of mean arterial blood pressure (MABP) and cardiac output (CO) is highly desired in clinical operations. Different methods have been proposed for controlling MABP, all methods have certain disadvantages according to patient model. In this article, the authors propose blood pressure control using integral reinforcement learning based fuzzy inference systems (IRLFI) based on parameter estimation techniques and have compared this method in terms of integral squared error (ISE), integral absolute error (IAE), integral time-weighed absolute error (ITAE), root mean square error (RMSE), convergence time (CT).

Published: September 2018

Semiconducting ruthenium silicide (Ru2Si3) polycrystalline thin films were grown by solid phase epitaxy using Ru-Si amorphous layers on Si substrates. The formation of Ru2Si3 phase was confirmed by XRD and Raman measurements when the amorphous layers were annealed at 600−900 °C in a vacuum. The Ru2Si3 thin films showed a low electron density of 1 × 1016 cm-3 with a high mobility of 430−940 cm2V-1s-1. Photoluminescence (PL) at ~0.8 eV was observed in the Ru2Si3 films.

Published: September 2018

Sb-doped β-FeSi2 epitaxial films on Si(111) were grown by molecular beam epitaxy to control an electron density of β-FeSi2. After an optimization of donor activation conditions in the Sb-doped β-FeSi2, the electron density of 6 × 1018 cm-3 at 300 K was achieved by thermal annealing in a N2 ambient. In the temperature dependence of carrier density, the n-type conduction was changed to p-type conduction at low temperatures in the film annealed at high temperature (600 °C). Raman spectra of the annealed films showed that both Fe and Si sites were substituted by the doped Sb in β-FeSi2 lattice.

Photoresistors based on amorphous Si-Sn thin films (270-285 nm) with different concentration of tin were studied by spectral measurements of photoconductivity at room temperature and by low-temperature measurements of the Hall effect . Electrical contacts to the Si-Sn film was formed by aluminum layer deposition. When the Al contact is illuminated, the spectral sensitivity of the photoresistor with Sn consentration of 19% extends to 2060 nm due to Schottky barrier influence. It was proved that the Si-Sn alloy film provides photoresponse with cut-off energy of 0.98 eV that is close to the indirect band gap in the Si-Sn film. Three deep acceptor levels with activation energies of 90, 114, and 173 meV were found in the Si-Sn thin film (20% Sn) in the temperature range of 50 – 300 K. Sequential activation of the deep levels and their competition leads to a nonmonotonic change of the Si-Sn film conductivity (0.025 - 5.0 (Ω×cm)-1) and mobility of holes (100 – 500 cm2/(V·s)). The transition to the intrinsic conductivity region of the amorphous Si-Sn film was not observed up to room temperature.
A Comparative Study on the Mechanical Properties of Clay Modified Epoxy Adhesive by Using Different Clay Types
Authors: Surip Siti Norasmah , Ismail A.H.
Published: September 2018

In this new world, polymer nanocomposites have developed to be one of the latest evolutionary steps in the polymer technology, besides showing a great deal to become the most versatile industrial advanced materials. In comparison with conventional composites, nanocomposites demonstrate significantly higher levels of mechanical performance with less content of particles. Thus, this study was carried out to investigate the effect of nano& micron size of clay particles to mechanical properties of epoxy adhesive. Three types of mechanical test were performed; tensile, impact and shear test. The result shows that the tensile strength was increase by using micron clay while shear and impact strength was increase by using nanoclay. The dispersion of clay in the epoxy adhesive is very important because it will affect the mechanical properties of epoxy adhesive itself. The function of clay to enhance the properties of epoxy adhesive is more effective when the clay is well dispersed. FESEM shows that the nanoclay was well dispersed in the epoxy adhesive while micron sized clay was partially intercalated.

As industry enters into high-tech society, the use of fossil energies is increasing. The demand of solar photovoltaic cell is increasing and according to this increase, the amount of waste photovoltaic cell will increase, too. However, compared to the increase of photovoltaic facility and technology, research about recycling method of waste photovoltaic cell is slow. Therefore, this study continued research to collect cooper and tin which are valuable metals from cooper ribbon electrode recovered from waste photovoltaic electrode. To effectively separate the coating layer when handling bulk of cooper ribbon electrode, heat treating furnace of hydrodynamic vibrating is developed and tin and cooper which are valuable metals are collected by using Hydro-metallurgical process used with nitric acid. The purity of cooper’s basic materials after heat treatment of hydrodynamic vibrating was 98.88wt.% and the purity of tin and cooper collected from the coating layer was measured as 98.07wt.% and 98.44wt.% each.

In this work, the properties of lead-free 0.92(Bi0.5Na0.42K0.08)TiO3-0.08(BaNb0.01Ti0.99)O3 or 92BNKT-8BNbT ceramic has been investigated. The sample was fabricated by a solid-state reaction technique. The 92BNKT-8BNbT sample was well sintered and dense with high density value of 5.86 g/cm3. X-Ray diffraction (XRD) patterns showed a single perovskite phase with tetragonal symmetry and no impurity or secondary phases. The microstructure was analysed using a scanning electron microscopy (SEM). Average grain size was measured and calculated based on a mean linear intercept method. The ceramics had a cubic-like grain shape with an average grain size of 0.39 µm. The influence of temperature on the dielectric and ferroelectric properties of the ceramic was investigated. The dielectric curves exhibited broad transition peaks at Td and Tm, which were the characteristics of a diffuse phase transition. The polarization-electric field (P-E) hysteresis loop changed from well-saturated at room temperature (RT) to pinched-type loop at high temperature (HT) and the remanent polarization decreased from 21.25 µC/cm2 (at RT) to 5.96 µC/cm2 (at 150 °C).
Oil and gas resource potential in the deep-water Canada Basin, Arctic Ocean
Authors: Dietrich J R , Chen Z , Hannigan P

Published: September 2018

The Canada Basin is a deep-water basin adjacent to the Arctic continental shelves of northwest Canada and northern Alaska. Perennial ice cover in the Arctic Ocean has historically prevented detailed geologic study of the basin. Recent seismic surveys (2007 to
2011) provide substantial new information on crustal architecture and sediment fill of the basin. These geophysical data provide a framework for a regional study of basin petroleum geology and resource potential. This report presents the first assessment of oil and gas potential in the Canada Basin.

Conventional petroleum resources in Canada Basin were evaluated with a volumetric play-based assessment method and an independent basin-scale global analogue method. The volumetric play assessment included quantitative analyses of four petroleum plays in Cenozoic strata. Mean estimates of total
recoverable resource potential in Canada Basin are 779 million m3 (4.9 billion barrels) oil, 659 billion m3 (23 Tcf) free gas, and 308 billion m3 (10.8 Tcf) solution gas. The total recoverable energy resource potential (oil and gas combined) is estimated at 1683 million m3 (10.5 billion barrels) oil
equivalent. The independent assessment based on the global analogue methodology provides mean estimates of total recoverable potential of 11 billion barrels oil equivalent, similar to the volumetric play estimates.
Natural gas hydrates may be a significant unconventional petroleum resource in Canada Basin, but an assessment of recoverable gas volumes was not possible with available data.
This assessment study provides important new insights into the natural resource endowment of the Arctic Canada Basin, a region with currently unresolved international jurisdiction issues.

Post-traumatic stress disorder symptom severity, trauma load and sleeping difficulties in trauma-exposed, treatment-seeking adolescents
Authors: Van Aarde Carissa , Nothling Jani , Armour Cherie , Seedat Soraya
Published: September 2018

Introduction: Sleep disturbances are associated with various anxiety- and trauma-related disorders, and specifically with post-traumatic stress disorder (PTSD). Two of the core symptoms of PTSD are recurrent distressing dreams about the traumatic event and difficulty in falling or staying asleep (insomnia). Sleep is essential for functioning, with poor sleep compromising cognitive, emotional and behavioural regulations. Sleep is also of particular importance for brain development and information processing in children and adolescents. The aim of this study was to determine if PTSD symptom severity and trauma load is associated with nightmares and insomnia in a sample of trauma-exposed, treatment-seeking adolescents.Methods: A total of 358 South African adolescents, between 12 and 18 years of age, exposed to at least one DSM-5 qualifying traumatic event, were assessed for PTSD-related sleep difficulties using the Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS). Childhood exposure to 10 common trauma types was also recorded using the KSADS trauma checklist. PTSD symptom severity was measured using the child PTSD checklist (CPC).Results: Adolescents reporting current trauma-related nightmares (F[268.2] = 0.68, t = -8.16, p = 0.000) and current insomnia (F[265.2] = 0.16, t = -9.03, p = 0.000) had significantly higher PTSD symptom severity scores compared to those without current nightmares and insomnia. Adolescents with current trauma-related nightmares (F[355.2] = 0.15, t = -3.30, p = 0.001) and insomnia (F[353.2] = 0.15, t = -2.51, p = 0.013) were also exposed to a significantly greater number of different trauma types compared to those without current nightmares and insomnia.Conclusion: Assessing and treating sleep difficulties related to PTSD in trauma-exposed adolescents, in an effort to reduce the developmental impact of trauma on the brain and general functioning, should not be overlooked. Longitudinal studies may contribute to a better understanding of the long-term effects of trauma-related insomnia and nightmares on mental and physical health outcomes.

Authors: A. Alareqi Manal , N. Al-Wesabi Fahd , T. Zahary Ammar , N. Ali Mansoor
Published: September 2018

Telecom industry will play a vital role in delivering Internet of Things (IoT) solutions and services. Researchers trust that IoT services deployment by Telecom is inevitable during the next few years. Nowadays, digital development overgrows, thus Telecom operators should consider IoT as the next evolution in their business plans. If an operator’s services confined to traditional services such as calling, they will lose a lot of added values and opportunities. In the end, they will find themselves out of the competition. Recently, the research community has addressed this topic and enriched it by highlighting related issues to help operators and researchers to move forward in this field. This paper presents a sound review for this topic covering the most significant related issues such as success elements, strategies and Low-Power Wide-Area (LPWA) standards provided by Telecom operators for IoT provision.

Abstract. Atmospheric chambers have been widely used to study secondary organic aerosol
(SOA) properties and formation from various precursors under different
controlled environmental conditions and to develop parameterization to
represent SOA formation in chemical transport models (CTMs). Chamber
experiments are however limited in number, performed under conditions that
differ from the atmosphere and can be subject to potential artefacts from
chamber walls. Here, the Generator for Explicit Chemistry and Kinetics of
Organics in the Atmosphere (GECKO-A) modelling tool has been used in a box
model under various environmental conditions to (i) explore the sensitivity
of SOA formation and properties to changes on physical and chemical
conditions and (ii) develop a volatility basis set (VBS)-type parameterization.
The set of parent hydrocarbons includes n-alkanes and 1-alkenes with 10, 14,
18, 22 and 26 carbon atoms, α-pinene, β-pinene and limonene,
benzene, toluene, o-xylene, m-xylene and p-xylene. Simulated SOA yields and
their dependences on the precursor structure, organic aerosol load,
temperature and NOx levels are consistent with the
literature. GECKO-A was used to explore the distribution of molar mass,
vaporization enthalpy, OH reaction rate and Henry's law coefficient of the
millions of secondary organic compounds formed during the oxidation of the
different precursors and under various conditions. From these explicit
simulations, a VBS-GECKO parameterization designed to be implemented in 3-D
air quality models has been tuned to represent SOA formation from the 18
precursors using GECKO-A as a reference. In evaluating the ability of
VBS-GECKO to capture the temporal evolution of SOA mass, the mean relative
error is less than 20 % compared to GECKO-A. The optimization procedure
has been automated to facilitate the update of the VBS-GECKO on the basis of
the future GECKO-A versions, its extension to other precursors and/or its
modification to carry additional information.

Abstract. The microphysical properties, composition and mixing state of mineral dust,
sea salt and secondary compounds were measured by active and passive aerosol
sampling, followed by electron microscopy and X-ray fluorescence in the
Caribbean marine boundary layer. Measurements were carried out at Ragged
Point, Barbados during June–July 2013 and August 2016. Techniques are
presented and evaluated, which allow for statements on atmospheric aerosol
concentrations and aerosol mixing state based on collected samples. It became
obvious that in the diameter range with the highest dust deposition the
deposition velocity models disagree by more than 2 orders of magnitude.
Aerosol at Ragged Point was dominated by dust, sea salt and soluble sulfates
in varying proportions. The contribution of sea salt was dependent on local wind
speed. Sulfate concentrations were linked to long-range transport from Africa and Europe, and
South America and the southern Atlantic Ocean. Dust sources were
located in western Africa. The dust silicate composition was not
significantly varied. Pure feldspar grains were 3 % of the silicate particles, of which about a third were K-feldspar. The average dust
deposition
observed was 10 mg m−2 d−1 (range of 0.5–47 mg m−2 d−1), of
which 0.67 mg m−2 d−1 was iron and 0.001 mg m−2 d−1
phosphorus. Iron deposition was mainly driven by silicate particles from
Africa. Dust particles were mixed internally to a minor fraction (10 %),
mostly with sea salt and less frequently with sulfate. It was estimated that
the average dust deposition velocity under ambient conditions is increased by the
internal mixture by 30 %–140 % for particles between 1 and 10 µm
dust aerodynamic diameter, with approximately 35 % at the mass median
diameter of deposition (7.0 µm). For this size, an effective
deposition velocity of 6.4 mm s−1 (geometric standard deviation of 3.1 over all
individual particles) was observed.
Long-term simulation of the boundary layer flow over the double-ridge site during the Perdigão 2017 field campaign
Authors: Wagner Johannes , Gerz Thomas , Wildmann Norman , Gramitzky Kira
Published: September 2018

Abstract. The Perdigao campaign 2017 was an international field campaign to measure the flow and its diurnal variation in the atmospheric boundary layer over complex terrain. A huge dataset of meteorological observations was collected over the double-hill site by means of state-of-the-art meteorological measurement techniques. A focus of the campaign was the interaction of the boundary layer flow with a single wind turbine, which was located on the south-western (SW) ridge top. In this study a long-term nested large-eddy-simulation (LES) of 49 days duration with a maximum horizontal resolution of 200 m is used to describe both the general meteorological situation over Spain and Portugal and the local small-scale flow structures over the double-hill during the intensive observation period (IOP). The simulations show that frequently observed nocturnal low-level jets (LLJ) from NE have their origin over the slopes of the elevated plateau between the Portuguese Serra da Estrela and the Spanish Sierra de Gata mountain ranges N and NE of Perdigao and that the diurnal clockwise turning of the wind direction over the double-ridge is induced by slope- and valley-winds under weak synoptic conditions. It is found that in spite of the long simulation time, modelled and observed wind structures on the ridge tops agree well, while along-valley flow within the valley is underestimated by the model.
The impact of spatiotemporal variability in atmospheric CO2 concentration on global terrestrial carbon fluxes

Published: September 2018

Abstract. Land carbon fluxes, e.g., gross primary production (GPP) and net biome
production (NBP), are controlled in part by the responses of terrestrial
ecosystems to atmospheric conditions near the Earth's surface. The Coupled
Model Intercomparison Project Phase 6 (CMIP6) has recently proposed increased
spatial and temporal resolutions for the surface CO2 concentrations
used to calculate GPP, and yet a comprehensive evaluation of the consequences
of this increased resolution for carbon cycle dynamics is missing. Here,
using global offline simulations with a terrestrial biosphere model, the
sensitivity of terrestrial carbon cycle fluxes to multiple facets of the
spatiotemporal variability in atmospheric CO2 is quantified.
Globally, the spatial variability in CO2 is found to increase the
mean global GPP by a maximum of 0.05 Pg C year−1, as more
vegetated land areas benefit from higher CO2 concentrations induced
by the inter-hemispheric gradient. The temporal variability in CO2,
however, compensates for this increase, acting to reduce overall global GPP;
in particular, consideration of the diurnal variability in atmospheric
CO2 reduces multi-year mean global annual GPP by
0.5 Pg C year−1 and net land carbon uptake by
0.1 Pg C year−1. The relative contributions of the different
facets of CO2 variability to GPP are found to vary regionally and
seasonally, with the seasonal variation in atmospheric CO2, for
example, having a notable impact on GPP in boreal regions during fall.
Overall, in terms of estimating global GPP, the magnitudes of the
sensitivities found here are minor, indicating that the common practice of
applying spatially uniform and annually increasing CO2 (without
higher-frequency temporal variability) in offline studies is a reasonable
approach – the small errors induced by ignoring CO2 variability
are undoubtedly swamped by other uncertainties in the offline calculations.
Still, for certain regional- and seasonal-scale GPP estimations, the proper
treatment of spatiotemporal CO2 variability appears important.
On the role of climate modes in modulating the air-sea CO2 fluxes in Eastern Boundary Upwelling Systems

Published: September 2018

Abstract. The air-sea CO2 fluxes in Eastern Boundary Upwelling Systems (EBUS) vary strongly in time and space with some of the highest flux densities globally. The processes controlling this variability have not yet been investigated consistently across all four major EBUS, i.e., the California (CalCS), Humboldt (HumCS), Canary (CanCS), and Benguela (BenCS) Current Systems. In this study, we diagnose the physical and biological mechanisms that contribute to historical (1920–2015) CO2 flux variability in these regions using simulation results from the Community Earth System Model Large Ensemble (CESM-LENS), a global coupled climate model ensemble that is forced by historical and RCP8.5 radiative forcing. Differences between simulations can be attributed entirely to internal climate variability. We find that the deviations from the ensemble mean, i.e., the anomalous CO2 fluxes, in the CalCS and CanCS are strongly affected by modes of variability associated with atmospheric subtropical gyres: the North Pacific Gyre Oscillation (NPGO) and the North Atlantic Oscillation (NAO), respectively. The CalCS (CanCS) has anomalous uptake (outgassing) of CO2 during the positive phase of the NPGO (NAO). The HumCS is mainly affected by El Niño Southern Oscillation (ENSO), with anomalous uptake of CO2 during an El Niño event. Variations in dissolved inorganic carbon (DIC) and sea surface temperature (SST) are the major contributors to these anomalous CO2 fluxes, and are generally driven by changes to gyre circulation, upwelling, the mixed layer depth, and biological processes. A better understanding of the sensitivity of EBUS CO2 fluxes to modes of climate variability may improve our ability to predict the ocean–atmosphere carbon cycle in EBUS, which are particularly susceptible to ocean acidification.
Variations of the Somali upwelling since 18.5 ka BP and its relationship with southwest monsoon rainfall
Authors: Balaji Durairaj , Bhushan Ravi , Chamyal Laxman Singh
Published: September 2018

Abstract. Somali upwelling history has been reconstructed for the last 18.5 ka BP based on
biogenic silica fluxes estimated from a sediment core retrieved from the
western Arabian Sea. Surface winds along the east African coast during the
southwest monsoon (SWM) cause the Somali upwelling; thus, the intensity of this
upwelling has been related to the variability of the SWM. Biogenic
silica flux variation suggests periodic weakening and strengthening of the
Somali upwelling. Weakened upwelling during the 18.5–15 ka BP period and strengthened
upwelling during the Bølling–Allerød (15–12.9 ka BP) suggest the onset of
the SWM. The Younger Dryas (12.9–11.7 ka BP) is marked
by reduced upwelling strength, with an intensification of the Somali upwelling
observed at the beginning of the Holocene and a further decline at 8 ka BP.
The increase in the upwelling strength recorded since 8 ka BP suggests SWM
strengthening during the latter part of the Holocene. A comparison of
upwelling variations with the SWM precipitation record
demonstrates a reversal in the relationship between the strength of the Somali
upwelling and SWM rainfall at the beginning of the Holocene.
This observed shift has been attributed to the variation in the SWM
strength due to the latitudinal shift of the intertropical
convergence zone (ITCZ) associated with changes in moisture sources.
Description and evaluation of NorESM1-F: A fast version of the
Norwegian Earth System Model (NorESM)

Abstract. A new computationally efficient version of the Norwegian Earth System Model (NorESM) is presented. This new version (here termed NorESM1-F) runs about 2.5 times faster (e.g. 90 model years per day on current hardware) than the version that contributed to the fifth phase of the Coupled Model Intercomparison project (CMIP5), i.e., NorESM1-M, and is therefore particularly suitable for multi-millennial paleoclimate and carbon cycle simulations or large ensemble simulations. The speedup is primarily a result of using a prescribed atmosphere aerosol chemistry and a tripolar ocean-sea ice horizontal grid configuration that allows an increase of the ocean-sea ice component time steps. Ocean biogeochemistry can be activated for fully coupled and semi-coupled carbon cycle applications. This paper describes the model and evaluates its performance using observations and NorESM1-M as benchmarks. The evaluation emphasises model stability, important large-scale features in the ocean and sea ice components, internal variability in the coupled system, and climate sensitivity. Simulation results from NorESM1-F in general agree well with observational estimates, and show evident improvements over NorESM1-M, for example, in the strength of the meridional overturning circulation and sea ice simulation, both important metrics in simulating past and future climates. Whereas NorESM1-M showed a slight global cool bias in the upper oceans, NorESM1-F exhibits a global warm bias. In general, however, NorESM1-F has more similarities than dissimilarities compared to NorESM1-M, and some biases and deficiencies known in NorESM1-M remain.
