The goal of pleural fluid assessment is to establish with certainty its etiology and major challenge is the etiologic diagnosis precocity. Pleural effusion as the first and the only event in the onset of non-Hodgkin lymphoma is atypically in the absence of other signs and symptoms. Follicular lymphoma (FL) also called indolent lymphoma the most frequent is a low-grade non-Hodgkin�s lymphoma (NHL). In patients with indolent lymphoma affecting the pleura and pericardium is atypical and appears only in aggressive forms, so the onset with pleural effusion is unusual. Serous effusions may occur from onset or during evolution of various subtypes of T cell originated lymphomas or high-grade B cell lymphomas. Primary pleural lymphomas (PPL) have been described at patients with human immunodeficiency virus infection; tuberculosis complicated with chronic pyothorax or after exposure to asbestos. Compared to other similar cases previously reported in the medical literature, the novelty of this case is the atypical onset of low grade of indolent B-cells non-Hodgkin with primary pleural effusion in the absence of personal history as well as of another clinical, laboratory and pleural changes.

Published: January 2020

The impact of sucrose and systemic cortisone treatment on the response of dentin was examined in an experimental rat model. After 2 months of a modified diet and/or medication period, the areas of dentin formation and dentinal caries were quantified in the mandibular molars of growing animals. The 60% sucrose diet significantly reduced dentin formation and increased dentinal caries progression. The presence of glucocorticoid medication alone reduced dentin formation. Cortisone medication in combination with sucrose diet further decreased dentin apposition. Rats receiving the control diet positively responded to the dentinal caries by increasing dentin formation to prevent pulpal exposure. The rate of dentine formation was lower in rats with high sucrose diet and predentin area was wider compared to the control group fed normal diet. The enlargement of the predentin region in sucrose diet rats reflects changes in the functionality of the odontoblasts, such as reduction of matrix synthesis and alteration of the mineralization process. These results indicate that the functional alterations in the pulpo-dentinal complex might contribute to dentinal caries progression through systemic mechanism irrespective of the causative factors.

Published: January 2020

Achieving the process of pyrolysis of biomass in mild conditions is a viable option for optimizing yield in liquid products and reducing coke yield. The partially dried digestate was stabilized by suspending in a reverse emulsion containing the lipid fraction resulting from the processing of the crude digestate, a hydrophobic surfactant of the polyethoxylated castor oil type and a hydrophilic sorbitol-polyethoxylated fatty acid ester type. The pyrolysis of the digestate was carried out in a continuous system, in a quartz tubular reactor, positioned in the central area of a vertical furnace provided with an automatic temperature control system. The experimental program was performed in the presence of two catalysts, Cu and respectively polyphosphoric acid at atmospheric pressure, temperature in the isothermal reaction zone 460 oC and liquid hourly space velocity of 0.33 h-1. The composition of the liquid fractions obtained on the two catalysts differs by the presence of a higher concentration of branched isomers in the case of the polyphosphoric acid catalyst.

Keratinophilic fungi are present in soil as decomposers of keratinous substrates, while keratinolytic fungi have the capacity to decompose native keratin, the insoluble fibrous proteins from living organism. Keratin materials, especially by-products from food industry and animal husbandry must be harnessed through innovative, non-polluting and low-cost solutions. The nonpathogenic keratinolytic fungal species produce extracellular keratinases which have many and various applications, one being in leather industry where dehairing process of skin and hides require keratinolytic activity. The present study investigates the biodegradative potential of selected keratinolytic fungal microorganisms expressed towards different types of animal skins. The ability of Fusarium sp. 1 A strain to produce keratinase with a good activity towards animal skins was confirmed. These results suggest that after further studies, Fusarium sp.1A could play an important role in processing of animal wastes.

Up till now, to our knowledge, there are no studies evaluating serum Brain - Derived Neurotrophic Factor (BDNF) levels in patients with degenerative chronic low back pain under rehabilitation treatment. BDNF is a neuroprotein associated with neuropathic pain and represents an important mediator of the effects of physical exercise. Complex balneal treatment with hot Techirghiol sapropelic mud reduces pain and increases serum levels of BDNF in these patients.

Mask is an important prognostic factor in patient�s compliance to positive airways pressure. As there are a lot�s of factors that contribute to a good interface choosing the right mask remains a challenge. The aim of this study was to evaluate the importance of mask and mask materials in treatment compliance to positive airway pressure in a sample of Romanian patients hospitalized for sleep study. Other factors that may have influence on the compliance were also evaluated (severity of sleep apnea, the presence of symptoms, comorbidities and the type of device used (CPAP or BiPAP). 107 patients with newly diagnosed sleep apnea were included. They received positive airways pressure treatment with nasal or oronasal mask depending on their own preference and tolerance and they were followed for one year. After one year 70% of 107 patients were still on positive airway pressure treatment (CPAP or BiPAP). There seemed to be no difference between the two masks when looking at the whole group. When analyzing the subgroups, however there seemed to be a preference for the nasal mask in patients who were treated with CPAP and oronasal mask in patients treated with BiPAP, suggesting that the associated conditions (COPD) might play an more important role than the mask itself. The materials did not influence the compliance.
Experimental Study on Biochemical Markers of Mandibular Bone Tissue Metabolism in Rats following the Implantation of PAW-1 and Geistlich Bio-OSS Collagen
Authors: Chetrus Viorica , Sarbu Dumitru , Gorea Corneliu , Chetrus Iulian
Published: January 2020

The study is based on the analysis of experimental results and determination of the bone metabolism markers by histochemical and biochemical methods performed on animals. The animals were implanted biovitroceramics PAW-1 in the mandible in the form of spongy matrix composed of fluorhydroxyapatite and microcrystallized wollastonite in a glass matrix, elaborated by the company PONETI (Romania) and Geistlich Bio-Oss-Collagen in the form of block (a mixture of granules, 0.25-1mm in size) and 10% fibers of porcine collagen. Geistlich Bio-Oss Collagen is a natural mineral bone of bovine origin, comparable both chemically and structurally to the mineralized human bone. It has a spongy consistency that allows simple modeling, and collagen facilitates the adaptation of the material on the defect site.The biochemical blood analysis showed an increased activity of bone thermolabile alkaline phosphatase over 30 days, the maximum being reached over 60 days + 20% (p[0.05) from the beginning of the experiment. The activity of tartrate-resistant bone acid phosphatase, on the contrary, decreased veridically by 22% over 60 days after implantation. Over 30 days after the beginning of the experiment under the action of the implanted material, the level of average molecules (AM) increased by 35% (p [0.05), while nucleotide substances (NS) increased by 51% (p [0.05). Within 60 days after implantation, the values of these indices showed a decreasing tendency. The fact mentioned above denotes that their osteoregenerative action increases under the influence of implanted materials.

Published: January 2020

Vogt-Koyanagi-Harada syndrome(VKH) is a multisystemic disorder characterized by granulomatous panuveitis and cutaneous, otorhynolaryngologic and neurologic involvement, due to an autoimmune reaction against melanocytic antigens. Autoinflammatory associations of VKH, including inflammatory bowel disease and psoriasis, were rarely described. SAPHO syndrome (an acronym for synovitis, acne, hyperostosis, pustulosis and osteitis) is a rare autoinflammatorymusculo-scheletal disease. This paper reports on a male patient presenting for long-lasting bone and joint pain, dysphagia,having a ten-year history of bilateral optic neuritiswhich required high-dose corticosteroids. Fundoscopy revealed diffuse chorioretinalnonpigmented atrophic lesions. Vitiligo, acne scars, clavicular deformity, recurrent chest pain and sacroiliitis pointed to a long-standing SAPHO syndrome and late-phase VKH. Blood tests found inflammation and anti-hepatitis C antibodies with repeatedly undetectable viremia. Bone scintigraphy with the characteristic bull�s head upper chest uptake and the radiographs confirmed SAPHO syndrome. The patient was treated with sulphasalazine and cyclosporin A, with alleviation of the articular and bony disease. In conclusion, SAPHO syndrome may add to the list of the diseases associated with VKH. Although VKH and SAPHO syndrome may have appeared coincidentally, a common pathogenesis involving an infectious trigger and IL-17 could be considered.

Although a number of prominent Church declared the Western imperialism and colonialism is not at all played an important role in the diffusion of the Christian religion and education in Indonesia, this paper, with a historical approach, read resource Indonesianis, Church, Islam, interviews and explanations of Christian figures competent in certain meetings, finds other things. The Christianization of Indonesia conducted through education is the historical fact of transnational movement of Christianity in Indonesia. The movement was a religious and educational shows by State actors and non-State since the days of colonialism and imperialism of Western mutual intertwinly. It's never "sterile" from the interests of the people and organizations concerning economic matters and politics.These findings contribute to the transnational studies by entering a transnational movement of Christians from Indonesia that has been more popular for the study of transnational Islamic movement or the transnational movement of world religions. This can be seen as a momentum to the start of the transnational movement studies in Christian Theological Seminary, Institute, and the Christian University in Indonesia.

Meskipun sejumlah tokoh gereja menyatakan kolonialisme dan imperialisme Barat sama sekali tidak berperan penting dalam difusi agama dan pendidikan Kristen di Indonesia, tulisan ini dengan pendekatan historis membaca sumber Indonesianis, gereja, Islam, wawancara dan penjelasan tokoh Kristen berkompeten di pertemuan tertentu menemukan hal lain. Kristenisasi Indonesia yang dilakukan lewat pendidikan merupakan fakta historis adanya gerakan transnasional Kristen di Indonesia. Gerakan itu memperlihatkan agama dan pendidikan oleh aktor negara dan non-negara sejak zaman kolonialisme dan imperialisme Barat saling anyam-mengayam. Itu tidak pernah “steril” dari kepentingan umat dan organisasi menyangkut hal-hal ekonomi dan politik. Temuan ini berkontribusi untuk studi transnasional dengan memasukkan gerakan transnasional Kristen dari Indonesia yang selama ini lebih popular untuk kajian gerakan Islam transnasional ataupun gerakan transnasional agama dunia. Ini bisa dilihat sebagai momentum dimulainya studi-studi gerakan transnasional di Sekolah Tinggi Teologi, Institute, dan Universitas Kristen di Indonesia.

Published: January 2020

Leadership is an instrument to achieve the vision, mission, goals, targets, and success of an organization, so we need a good leadership. With good leadership a leader can achieve goals and be able to manage conflicts / obstacles that may occur in the leadership process. From this problem the authors conducted an analysis of the concept of Nehemiah's leadership, because Nehemiah was a leader who was able to rebuild the wall of Jerusalem that had been damaged. The author analyzes the biblical texts and various literatures relevant to the topic. The analysis shows that Nehemiah's leadership is visionary and inspirational leadership. The leadership is relevant to the management of Christian Religious Colleges in Indonesia (PTKKI) because it is built on the foundation of true spirituality, guided by a clear vision, a good management process.

Kepemimpinan merupakan instrumen untuk mencapai visi, misi, tujuan, target, dan kesuksesan suatu organisasi, sehingga diperlukan sebuah kepemimpinan yang baik. Dengan kepemimpinan yang baik seorang pemimpin dapat mencapai tujuan serta mampu memanajemeni konflik/rintangan yang mungkin terjadi dalam proses kepemimpinan itu. Dari masalah tersebut penulis melakukan analisis terhadap konsep kepemimpinan Nehemia, karena Nehemia merupakan tokoh pemimpin yang mampu membangun kembali tembok Yerusalem yang telah rusak. Penulis melakukan analisis pustaka terhadap teks Alkitab dan berbagai literatur yang relevan dengan topik tersebut. Dari hasil analisis tampak jika kepemimpinan Nehemia adalah kepemimpinan yang visioner dan inspiratif. Kepemimpinan tersebut relevan dengan pengelolaan Perguruan Tinggi Keagamaan Kristen di Indonesia (PTKKI) karena dibangun di atas dasar spiritualitas yang benar, dituntun oleh visi yang jelas, dan proses manajemen yang baik.

Church music has long history and experiences in its periods. It began when they, the believers, mentioned themselves as the “Christian”. From the time that phenomenon the christians commenced their act of devotion tradition included their musical tradition of worship. The existence of church music more developed till Middle Age or Dark Age Period. It was dominantly covering to others music genre. At the Renaisance Period, the church reformation movement occured and it was pioneered by Martin Luther. Western music changed at the time. Luther changed of scene; He changed the tradition of Catholic church that used Latin lirics to folk language; He changed the gregorian chant tradition with folksong. The phenomenon was the first time of event of inculturation in world history of music after it undergone stagnancy during the authorization of Roman empire, especially when Pope Gregory created the standarization to all christian music. At the present day we are familiar with charismatic music tradition which is developed from American music tradition. It has a characteristic which is used as the band instrument in praise and worship by christian believers. But sometimes, the believers also use arpeggio or broken-chord as the main charracter on Classical Period in part the way of Western music history. Pass through the reasearch, the reasearcher look into the idioms are used in praise and worship in charismatic church. The reasearcher found that the using of idiom in Classical Period has enriched the nuance of music aesthetic in praise and worship.
The Extreme CNO-enhanced Composition of the Primitive Iron-poor Dwarf Star J0815+4729*
Authors: Hernández Jonay I. González , Aguado David S. , Prieto Carlos Allende , Burgasser Adam J. , Rebolo Rafael
Published: January 2020

We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high-quality data allow us to derive a metallicity of [Fe/H] = −5.49 ± 0.14 from the three strongest Fe i lines and to measure a high [Ca/Fe] = 0.75 ± 0.14. The large carbon abundance of A(C) = 7.43 ± 0.17 (or [C/Fe] ∼ 4.49 ± 0.11) places this star in the upper boundary of the low-carbon band in the A(C)–[Fe/H] diagram, suggesting no contamination from a binary AGB companion. We detect the oxygen triplet at 777 nm for the first time in an ultra-metal-poor star, indicating a large oxygen-to-iron abundance ratio of [O/Fe] = 4.03 ± 0.12 (A(O) = 7.23 ± 0.14), significantly higher than the previously most metal-poor dwarf J2209–0028 with an oxygen triplet detection with [O/Fe] ∼ 2.2 dex at [Fe/H] ∼ −3.9. Nitrogen is also dramatically enhanced with (A(N) = 6.75 ± 0.08) and an abundance ratio [N/Fe] ∼ 4.41 ± 0.08. We also detect Ca, Na, and Mg, while providing upper limits for eight other elements. The abundance pattern of J0815+4729 resembles that of HE 1327–2326, indicating that both are second-generation stars contaminated by a ∼21–27 M
⊙ single, zero-metallicity, low-energy supernova with very little mixing and substantial fallback. The absence of lithium implies an upper limit abundance A(Li) < 1.3 dex, about 0.7 dex below the detected Li abundance in J0023+0307, which has a similar metallicity, exacerbating the cosmological lithium problem.
Diverse views among scientists on non-native species
Authors: Gbedomon Rodrigue C. , Salako Valère K. , Schlaepfer Martin A.
Published: January 2020

Conservation scientists have traditionally viewed non-native species (NNS) as potential threats to native biodiversity. Here, we question whether alternative views of NNS exist in the scientific community that stand in contrast to the dominant narrative that emerges from the literature. We asked researchers from the biological, social, and environmental sciences to participate in an anonymous poll regarding the perceived values and threats of NNS. Some 314 individuals responded, approximately half of whom were biologists and half were social or environmental scientists. We grouped responses into three statistical clusters defined by shared responses. We then analyzed the correlation of responses to individual questions and membership of clusters with predictor variables age, gender, and field of work. Overall, a majority of respondents in our sample supported statements that the species-component of biodiversity should include all species (55%) or some types of non-native species (an additional 32%), which contrasts with the manner in which major biodiversity assessments and indicators are constructed. A majority of respondents in our sample (65%) also supported that measurement of the impact of invasive species should be based on the net biological, social, and economic effects, which also represents a marked departure from current methods that focus only on the adverse effects of a subset of NNS considered as invasive. Field of work and age were correlated with clusters and numerous individual responses. For example, biologists were three-times more likely than non-biologists to support a definition of species richness that included only native species. Two clusters (Cluster 1 and Cluster 3), mainly composed of non-biologists and biologists, respectively, differed in their support for statements that NNS would provide useful ecosystem services in the future (66% and 40%, respectively). Thus, a key result of this study is that a variety of normative stances regarding NNS is present within the scientific community. Current international indicators of progress (e.g., Aichi Targets) capture only a “nativist” set of values, which, if our sample is representative of the scientific community, appears to be a minority view. Therefore, we argue that indicators should be modified to integrate the diversity of views that exist within the scientific community.
L’art pour sortir de l’échec scolaire
Authors: Deborde Julie
Published: January 2020

Alors que l’école peine à réduire l’échec scolaire et à fournir des réponses adaptées à chacun, des projets partenariaux d’ateliers artistiques menés au sein de certaines classes proposent une alternative dans la remédiation à la grande difficulté scolaire. Les actions artistiques permettent à ces élèves de s’investir dans un domaine où l’échec n’existe pas, de sortir du cadre habituel, et ainsi de faire un pas de côté. Cet article repose sur une enquête menée au sein de La Source, une association créée en 1991 par le peintre Gérard Garouste, qui s’avère être un terrain adapté pour étudier la remédiation scolaire par l’art.
L’avenir de la librairie est devant elle
Authors: Rimaud Mathilde
Published: January 2020

Le marché du livre français se distingue de celui d’autres pays par la présence d’un réseau encore dense de librairies indépendantes, dont le nombre diminue régulièrement mais reste néanmoins important, sur un marché du livre par ailleurs atone. Non, la lecture n’est pas morte, différentes études en témoignent ; non, Internet, et au premier chef le dragon Amazon, ne domine pas encore tout le marché, bien que les ventes en ligne bousculent les différents canaux depuis une vingtaine d’années. Comment expliquer la relative résistance des librairies indépendantes, quand on constate par ailleurs les stratégies de fusion des plus grandes structures (Furet du Nord/Decitre, Fnac/Darty…) ou la fragilité de certains groupes (France Loisirs, Virgin, Chapitre…) ? Quelles stratégies développent-elles et quels sont les impacts des aides publiques et du collectif ? À quels enjeux font-elles face aujourd’hui (transmission, fidélisation, différenciation, services…) et avec quels moyens ? Peuvent-elles compter sur un changement de comportement des consommateurs, tel celui qui se manifeste à travers un mouvement comme IndieBound dans les pays anglo-saxons ?

The Caribbean and its Linkages with the World
Authors: Vargas Mauricio , Hess Daniela
Published: January 2020

Using data from 1980-2017, this paper estimates a Global VAR (GVAR) model taylored for the Caribbean region which includes its major trading partners, representing altogether around 60 percent of the global economy. We provide stilyzed facts of the main interrelations between the Caribbean region and the rest of the world, and then we quantify the impact of external shocks on Caribbean countries through the application of two case studies: i) a change in the international price of oil, and ii) an increase in the U.S. GDP. We confirmed that Caribbean countries are highly exposed to external factors, and that a fall in oil prices and an increase in the U.S. GDP have a positive and large impact on most of them after controlling for financial variables, exchange rate fluctuations and overall price changes. The results from the model help to disentangle effects from various channels that interact at the same time, such as flows of tourists, trade of goods, and changes in economic conditions in the largest economies of the globe.

Published: January 2020

This paper provides an overview of the strategic and operational issues as well as institutional challenges, related to the implementation of the Sovereign Asset and Liability Management
(SALM) approach. Application of an SALM framework allows the authorities to identify and monitor sovereign exposure mismatches; increase resilience to foreign currency and interest rate risks; and thus, strengthen financial stability; and implement more cost-effective management of the public-sector debt. The analysis is based on emerging market (EM) countries and illustrated by the experience of Uruguay, using data as of end-2017.
Innovate to Lead or Innovate to Prevail
Authors: Piazza Roberto , Zheng Yu
Published: January 2020

This paper extends the Schumpeterian model of creative destruction by allowing followers’ cost of innovation to increase in their technological distance from the leader. This assumption is motivated by the observation the more technologically ad- vanced the leader is, the harder it is for a follower to leapfrog without incurring extra cost for using leader’s patented knowledge. Under this R&D cost structure, leaders innovate to increase their technological advantage so that followers will eventually stop innovating, allowing leadership to prevail. A new steady state then emerges featuring both leaders and followers innovating in few industries with low aggregate growth.
Managed Trade

Published: January 2020

The trade discussions between the U.S. and China are on-going. Not much is known about the shape and nature of a potential agreement, but it seems possible that it would include elements of managed trade. This paper attempts to examine the direct, first-round spillover effects for the rest of the world from managed trade using three approaches. The results suggest that, in the absence of a meaningful boost in China’s domestic demand and imports, bilateral purchase commitments are likely to generate substantial trade diversion effects for other countries. For example, the European Union, Japan, and Korea are likely to have significant export diversion in a potential deal that includes substantial purchases of U.S. vehicles, machinery, and electronics by China. At the same time, a deal that puts greater emphasis on commodities would put small commodity exporters at a risk. This points to the advantages of a comprehensive agreement that supports the international system and avoids managed bilateral trade arrangements.

The main lessons are: i) average additional spending across SSA is significant, at 19 percent of GDP in 2030; ii) countries must prioritize their development objectives according to their capacity to deliver satisfactory outcomes, iii) financing strategies should articulate multiple sources given the scale of additional spending, and iv) strong national ownership of SDGs is key and should be reflected in long-term development plans and medium-term policy commitments.
Is Digitalization Driving Domestic Inflation?
Authors: Csonto Balazs , Huang Yuxuan , Tovar Mora Camilo
Published: January 2020

This paper examines the extent to which digitalization—measured by a new proxy based on IP addresses allocations per country—has influenced inflation dynamics in a sample of 36 advanced and emerging economies over 2000-2017. Phillips curve estimates show that digitalization has a statistically significant negative effect on inflation in the short run. Its economic impact is not large but has increased since 2012 and mainly operates through a cost/competition channel. Principal components and cointegration analysis further suggest digitalization is a key driver of lower trend inflation.
Deepening the EU’s Single Market for Services
Authors: Ebeke Christian , Frie Jan-Martin , Rabier Louise
Published: January 2020

The services sector is increasingly important for the euro area economy, but productivity growth in the sector has stalled over the past two decades. Remaining barriers to cross-border trade in services within the EU Single Market contribute to this weak performance. Our empirical analysis suggests that slow progress in tackling these barriers is associated with political economy factors such as weak government support in parliaments, low government efficiency and high markups. To remove the cross-border restrictions on services trade, we suggest combining incentives such as financial support, technical assistance and improved communication on barriers with more effective enforcement.
The Dynamics of Non-Performing Loans during Banking Crises
Authors: Ari Anil , Chen Sophia , Ratnovski Lev
Published: January 2020

This paper presents a new dataset on the dynamics of non-performing loans (NPLs) during 88 banking crises since 1990. The data show similarities across crises during NPL build-ups but less so during NPL resolutions. We find a close relationship between NPL problems—elevated and unresolved NPLs—and the severity of post-crisis recessions. A machine learning approach identifies a set of pre-crisis predictors of NPL problems related to weak macroeconomic, institutional, corporate, and banking sector conditions. Our findings suggest that reducing pre-crisis vulnerabilities and promptly addressing NPL problems during a crisis are important for post-crisis output recovery.
What is the Impact of Increased Business Competition?
Authors: Feliz Sonia , Maggi Chiara
Published: January 2020

This paper studies the macroeconomic effect and underlying firm-level transmission channels of a reduction in business entry costs. We provide novel evidence on the response of firms' entry, exit, and employment decisions. To do so, we use as a natural experiment a reform in Portugal that reduced entry time and costs. Using the staggered implementation of the policy across the Portuguese municipalities, we find that the reform increased local entry and employment by, respectively, 25% and 4.8% per year in its first four years of implementation. Moreover, around 60% of the increase in employment came from incumbent firms expanding their size, with most of the rise occurring among the most productive firms. Standard models of firm dynamics, which assume a constant elasticity of substitution, are inconsistent with the expansionary and heterogeneous response across incumbent firms. We show that in a model with heterogeneous firms and variable markups the most productive firms face a lower demand elasticity and expand their employment in response to increased entry.
Exchange Rate Volatility and Pass-Through to Inflation in South Africa
Authors: Miyajima Ken
Published: January 2020

Does the South African rand’s relatively large volatility affect inflation? To shed some light on this question, a standard estimation technique of exchange rate pass-through to inflation is extended to incorporate exchange rate volatility. Estimated results suggest that higher exchange rate volatility tends to increase core inflation but to a relatively limited extent in South Africa. The finding lends support to the policy of allowing the rand to float freely and work as a shock absorber, consistent with the nation’s successful inflation targeting regime.
Evidence for impacts on surface-level air quality in the northeastern US from long-distance transport of smoke from North American fires during the Long Island Sound Tropospheric Ozone Study (LISTOS) 2018
Authors: Rogers Haley M. , Ditto Jenna C. , Gentner Drew R.
Published: January 2020

Abstract. Biomass burning is a large source of uncontrolled air
pollutants, including particulate matter (i.e., PM2.5), black carbon
(BC), volatile organic compounds (VOCs), and carbon monoxide (CO), which
have significant effects on air quality, human health, and climate.
Measurements of PM2.5, BC, and CO made at the Yale Coastal Field
Station in Guilford, CT, and five other sites in the metropolitan New York
City (NYC) area indicate long-distance transport of pollutants from
wildfires and other biomass burning to surface-level sites in the region.
Here, we examine two such events occurring on 16–17 and 27–29 August 2018. In addition to regionally consistent enhancements
in the surface concentrations of gases and particulates associated with
biomass burning, satellite imagery confirms the presence of smoke plumes in
the NYC–Connecticut region during these events. Back-trajectory modeling
indicates that air masses arriving at surface-level sites in coastal
Connecticut on 16–17 August passed over the western coast of
Canada, near multiple large wildfires. In contrast, air parcels arriving on
27–29 August passed over active fires in the southeastern
United States. The results of this study demonstrate that biomass burning
events throughout the US and Canada (at times more than 4000 km away),
which are increasing in frequency, impact surface-level air quality beyond
regional scales, including in NYC and the northeastern US.
Modelling the effect of condensed-phase diffusion on the homogeneous nucleation of ice in ultra-viscous particles
Authors: Fowler Kathryn , Connolly Paul , Topping David
Published: January 2020

Abstract. Computational models of cloud formation typically use homogeneous nucleation to predict the ice nucleated in supercooled water.
However, the existence of ultra-viscous organic aerosol in the upper troposphere has offered alternative ice nucleation pathways, which have been observed in laboratory studies. The possible effects of aerosol viscosity on cloud microphysical properties have traditionally been interpreted from simple model simulations of an individual aerosol particle based on equilibration timescales.
In this study, to gain insight into the formation of ice in an ensemble of ultra-viscous aerosol particles, we have developed the first cloud parcel model with bin microphysics to simulate condensed phase diffusion through each individual aerosol particle.
Our findings demonstrate, for the first time, the complex relationship between the rate of ice formation and the viscosity of secondary organic aerosol, driven by two competing effects – which cannot be explained using existing modelling approaches. The first is inhibition of homogeneous ice nucleation below 200 K, due to restricted particle growth and low water volume. The second occurs at temperatures between 200 and 220 K, where water molecules are slightly more mobile, and a layer of water condenses on the outside of the particle, causing an increase in the number of frozen aerosol particles. Our new model provides a basis to better understand and simulate ice cloud formation on a larger scale, addressing a major source of uncertainty in climate modelling through the representation of microphysical cloud processes.
Differences in tropical high clouds among reanalyses: origins and radiative impacts

Abstract. We examine differences among reanalysis high cloud products in the tropics, assess the impacts of these differences on radiation budgets at the top of the atmosphere and within the tropical upper troposphere and lower stratosphere (UTLS), and discuss their possible origins in the context of the reanalysis models. We focus on the ERA5, ERA-Interim, JRA-55, MERRA-2, and CFSR/CFSv2 reanalyses, with MERRA included in selected comparisons. As a general rule, JRA-55 produces the smallest tropical high cloud fractions and cloud water contents among the reanalyses, while MERRA-2 produces the largest. Accordingly, cloud radiative effects are relatively weak in JRA-55 and relatively strong in MERRA-2. Only MERRA-2 and ERA5 among the reanalyses produce tropical-mean values of outgoing longwave radiation (OLR) close to observed, but ERA5 tends to underestimate cloud effects while MERRA-2 tends to overestimate variability. ERA5 also produces distributions of longwave, shortwave, and total cloud radiative effects at top-of-atmosphere that are very consistent with observed. The other reanalyses all exhibit substantial biases in at least one of these metrics, although compensation between the longwave and shortwave effects helps to constrain biases in the total cloud effect for most reanalyses. The vertical distribution of cloud water content emerges as a key difference between ERA-Interim and the other reanalyses. Whereas ERA-Interim shows a monotonic decrease of cloud water content with increasing height, the other reanalyses all produce distinct anvil layers. The latter is in better agreement with observations and yields very different profiles of radiative heating in the UTLS. For example, whereas the altitude of the level of zero net radiative heating tends to be lower in convective regions than in the rest of the tropics in ERA-Interim, the opposite is true for the other four reanalyses. Differences in cloud water content also help to explain systematic differences in diabatic ascent in the tropical lower stratosphere among the reanalyses. We discuss several ways in which aspects of the cloud and convection schemes impact the tropical environment. Discrepancies in the vertical profile of moist static energy in convective regions are particularly noteworthy, as this metric is based exclusively on variables that are directly constrained by data assimilation.
