Authors: Mohapatra Devi Prasad , Sahoo Jaya Prakash , Mohaptra Madhusmita Mohanty , Kar Sitanshu Sekhar , Kalyani Sridharan , Roy Ayan
Published: May 2020

BACKGROUND: Obesity is one of todayâ€™s most neglected public health problems, affecting every region of the world. Early identification of increased weight gain among the population is paramount to prevent the attendant complications associated with obesity.
OBJECTIVES: The primary objective of this study was to measure the distribution of L score in the representative population and the secondary objective was to identify an association between L score values and other measures of obesity such as body mass index, waist circumference, waist-to-height ratio, neck circumference (NC), and total body fat percentage.
METHODS: This study was conducted in the departments of plastic surgery and endocrinology of a tertiary care institute. The L score (a measure of fullness of the lateral retromalleolar fossa in the lower limb) was assessed in all the participating individuals. Statistical analysis was performed using the Statistical Package for the Social Sciences version 19.0. p < 0.05 was considered as statistically significant in statistical analysis.
RESULTS: Among the 50 participants taken in this study, 24 had L score 0, 15 had score 1, and 11 had score 2. The participants with L score 1 and 2 had higher obesity, higher NC, and more body fat percentage compared to those having score 0. All the participants with L score 2 were overweight and had central obesity.
CONCLUSIONS: The L score measure has a potential for simple and rapid screening of at-risk population for overweight and obesity.

Published: May 2020

BACKGROUND: The World Health Organization calls patient safety â€œan endemic concern.â€ Keeping patients safe is viewed as a global public health problem and a human rights issue. An environment where safety culture prevails is considered the biggest obstacle to improve patient safety. Proactive efforts to identify, prevent, and eliminate errors have the potential to significantly improve safety. Pediatric intensive care unit (PICU) is high-hazard and -risk environments.
AIM: The aim of this study is to enhance compliance to patient safety practices within the general PICUs in Cairo University Childrenâ€™s Hospital.
METHODS: This is a pretest-posttest interventional study. A tailored intervention after the baseline assessment was designed and implemented followed by reassessment. All physicians and nurses present in the general PICUs who were available and consented participated in the study. A questionnaire for knowledge and attitude and a checklist for practice assessment of the participants were used.
RESULTS: The median age of the participants was 30 years and interquartile range (28â€“40). There was a statistically significant difference between those who received patient safety training and those who did not in patient safety knowledge. The median knowledge score increased significantly after the intervention. Regarding the attitude of the studied personnel toward their perception of patient safety cultureâ€™s dimensions before and after the intervention, there was no statistically significant difference in some dimensions and a statistically significant improvement in some others.
CONCLUSION: The strategies based on patient safety awareness-raising among health-care providers together with commitment and enthusiasm among senior leadership in the hospital can potentially improve compliance with practice and consequently lead to better patient safety.

Published: May 2020

OBJECTIVE: The objective of the study was to evaluate the specific work activities and occupational exposure to respiratory hazards as predictors of chronic respiratory symptoms development, lung function decline, and respiratory health impairment among crop farmers. METHODS: A cross-sectional survey was performed, including 87 crop farmers (mean age: 53.4 Â± 7.8 years; and mean exposure duration: 22.9 Â± 7.8 years) and 80 office workers as a control group (mean age: 52.7 Â± 8.2 years) matched for age, smoking habits, and socioeconomic status. Subjects were evaluated by a questionnaire on respiratory symptoms in the past 12 months and spirometry testing. RESULTS: Crop farmers had a significantly higher prevalence of cough (41.4), phlegm (28.7%), and dyspnea (21.8%), than controls (p < 0.05). All mean baseline spirometric parameters were lower in crop farmers, but statistical significance was confirmed only for MEF25, MEF50, and MEF75 (p = 0.003, p = 0.000, and p = 0.001, respectively). Most of the respiratory symptoms were significantly associated with common work activities of crop farmers and all-day exposure to certain respiratory hazards. Age, exposure duration, and their combined effect with smoking habit had a significant effect on forced expiratory volume in one second FEV1 and FEV1/forced vital capacity. CONCLUSION: The results confirm that occupational exposure among crop farmers is associated with higher prevalence of respiratory symptoms and lung function decline and, together with specific workflow activities, may not only be a predictors of respiratory health impairment, but also a key tool in the creation of preventive strategies.
Grasshopper populations respond similarly to multiple moderate intensity livestock grazing treatments
Authors: Branson David H.
Published: May 2020

Livestock grazing frequently affects grasshopper populations, but no prior studies have simultaneously examined a wide range of moderate intensity livestock grazing treatments in the Northern Great Plains. Grasshopper densities varied significantly between years, but five moderate grazing treatments, including both rotational and continuous grazing treatments, did not differentially affect grasshopper densities or species composition. Grasshopper populations appear resilient to different types of moderate grazing at this Northern Great Plains mixed-grass prairie site.
Attendre sans espérer
Authors: Constantinidès Yannis
Published: May 2020

Est-il éthique de laisser espérer un hypothétique salut à un patient dont le pronostic est très réservé ? L’espérance est certes une précieuse consolation et peut-être même un adjuvant efficace pour certains, mais on peut légitimement s’interroger sur ce retour furtif du religieux en médecine. Contrairement à l’espoir mesuré et fondé, l’espérance reste en effet vague et indéterminée. Elle est du reste indissociable de la crainte, ce qui en fait une valeur pour le moins ambivalente. Les jugements portés sur elle sont de fait très partagés : vertu suprême pour les uns, l’espérance apparaît sinon immorale, du moins pernicieuse aux autres. Si les positions sont aussi tranchées, c’est parce qu’elle conditionne en réalité la manière d’aborder cette vie. L’espérance béate empêche de vivre au présent, retardant toujours le moment de l’accomplissement de soi. À cette perpétuelle fuite en avant, il faut opposer l’attente confiante, qui permet de se recentrer sur soi et de ne plus attendre son salut de l’extérieur. Il convient en effet de réhabiliter l’attentisme, qui n’est pas forcément synonyme de passivité mais peut être préparation intérieure à la saisie du kairos , du moment opportun. Se dessinent ainsi les contours d’une éthique de l’attente, qui rend caduques aussi bien l’espérance que la crainte.
Intuition : génie ou folie ?
Authors: Lecointre Cécile
Published: May 2020

Qu’elle vienne des parents ou des soignants, que faire de l’intuition, troublante petite voix, lorsque que nous prenons des décisions concernant la santé de l’enfant ? Dans ce travail, nous questionnons les rapports que l’intuition entretient avec la production de savoirs, le réel, le risque, et le temps. Nous tentons de circonscrire le phénomène et d’interroger sa place dans la pratique clinique actuelle. C’est dans les spécificités de l’objet et des acteurs du soin — le vivant — que s’enracine ce mode alternatif d’appréhension des situations. Il s’agit de remettre le sujet — décideur — au cœur du processus de décision. En effet, à la frontière entre la science et l’art, la pratique du soin semble peiner à répondre à l’idéal positiviste, créant ainsi des situations d’incertitude parfois impénétrables. Quand nos réponses classiques peinent à rendre compte de la complexité du vivant, pouvons-nous compter sur une faculté aussi insaisissable qu’imprévisible : l’intuition? D’ailleurs, que sont ces « intuitions » ? Pouvons-nous avoir confiance en ce « savoir sans savoir pourquoi » ? Est-il (ir)responsable d’oser l’intuition ? Serait-ce au contraire faire preuve de génie ? Si notre réflexion se porte sur le contexte de la clinique en pédiatrie, il semble néanmoins être transposable à d’autres situations de soin, se rapprochant notamment du « gut feelings » proposé pour la pratique de la médecine générale.
Lab Networks in Engineering Education: A Proposed Structure for Organizing Information
Authors: Romagnoli Giovanni , Esposito Giovanni , Rizzi Antonio , Zammori Francesco , Bertolini Massimo , Uckelmann Dieter
Published: May 2020

Experimentation plays an essential role in engineering education, allowing to balance theoretical proofs and emphasis on physical intuition. Laboratories can fulfil several goals at once, but they also involve high costs, mostly due to equipment, space, and human resources for operating and maintaining them. Remote-access labs have been proposed as a feasible alternative: developed since the early 2000s by an ever-increasing research community, they are real or virtual labs accessible at distance through a computer network. Recently, alternative bibliometric taxonomies and classifications of current networked remote-access labs have been proposed. Yet, none of these works proposes a comprehensive structure to collect and organize the information, especially from a technical perspective, aiming at the definition of the state of the art and future outlooks of provided solutions. In the present work, we fill this gap extending previous works by enlarging their set of criteria towards a general multi-layer model for networked remote-access labs. We performed a systematic review of relevant literature to retrieve useful information to design the structure and then validated it by using a mini-Delphi method.

Published: May 2020

The Aims of this paper is to analyze the influence of Remote Lab on overcoming the limitation of practicum facilities. This study uses qualitative research methods. In this study, the researchers conducting a study of the use of remote labs in overcoming the unavailability of laboratory equipment. 1). The completeness of practicum equipment available at SMKs is still inadequate, only around 30%. Some students stated that when carrying out practical activities, each tool used by 4 students simultaneously made the practicum process not run effectively and often there was discrimination only intelligent students who could complete the sequence, then some students also stated that the existing components many have been damaged. Another statement expressed by students that not all productive subjects can be practiced because of limited equipment that can be caused by several factors including: a) inadequate school budget; b) tools and practice materials that are difficult to obtain; 2) The Remote LAB application sends data at any time when selecting a Lab, selecting a Gate, and selecting input from a gate. The output of the gate will be measured using a multi-meter and oscilloscope and will be monitored directly via YouTube streaming, so that it can be monitored in real time on the Remote LAB Android application; 3) Practical experience does not have to be identical in a laboratory room on a supervised Schools. Students receive tangible observations using real equipment to arrive at concrete conclusions, as well as assessing them in a physical laboratory with equipment so that it will be beneficial to improve their laboratory abilities.
Using Random Forest Algorithm to Model Cold-Stunning Events in Sea Turtles in North Carolina

Published: May 2020

Sea turtle strandings due to cold-stunning are seen when turtles are exposed to ocean temperatures that acutely and persistently drop below approximately 12°C. In North Carolina, this syndrome affects imperiled loggerhead Caretta caretta, green Chelonia mydas, and Kemp's ridley Lepidochelys kempii sea turtle species. Based on oceanic and meteorological patterns of cold-stunning in sea turtles, we hypothesized that we could predict the daily size of cold-stunning events in North Carolina using random forest models. We used cold-stunning data from the North Carolina Sea Turtle Stranding and Salvage Network from 2010 to 2015 and oceanic and meteorological data from the National Data Buoy Center from 2009 to 2015 to create a random forest model that explained 99% of the variance. We explored additional models using the 10 and 20 most important variables or only oceanic and meteorological variables. These models explained similar percentages of variance. The variables most frequently found to be important were related to air temperature, atmospheric pressure, wind direction, and wind speed. Surprisingly, variables associated with water temperature, which is critical from a biological perspective, were not among the most important variables identified. We also included variables for the mean change in these metrics daily from 4 d before the day of stranding. These variables were among the most important in several of our models, especially the change in mean air temperature from 4 d before stranding to the day of stranding. The importance of specific variables from our random forest models can be used to guide the selection of future model predictors to estimate daily size of cold-stunning events. We plan to apply the results of this study to a predictive model that can serve as a warning system and to a downscaled climate projection to determine the potential impact of climate change on cold-stunning event size in the future.

Published: May 2020

Ramie solid waste as chips can be used as raw material for pulp. Ligninolytic enzymes of laccase widely used for pretreatment of the pulping process of ramie chips by biodelignification using laccase produced byPenicilliumsp. LX/08 has been done. This study aims to obtain optimal concentrations of lignin and CuSO4as enzyme inducers to increase laccase production fromPenicilliumsp. LX/08 during biodelignification process and its effect on the quality of ramie pulp. The biodelignification process of ramie chips was carried out by solid state fermentation (SSF) method with six days incubation time. Two inducer type treatment factors (CuSO4and lignin), and variations in the concentration of each lignin (0.25 g/L, 0.5 g/L, 0.75 g/L) and CuSO4(0.25 mM, 0.5 mM, 0.75 mM) were investigated in this study. The pulping process was carried out by the soda process in a digester under conditions: 12% active alkaline, temperature of 165°C for 3.5 hours. The results showed that 0.75 mM and 0.5 g/L of lignin were the optimal concentrations which could increase the laccase activity ofPenicilliumsp. LX/08 by 343 U/L and 25,8 U/L, respectively. The quality of ramie pulp showed a decrease in Kappa Number of 9,34% with an increase in pulp yield to 55,43%. Based on these results, the pretreatment method using laccase produced byPenicilliumsp. LX/08 can assist the pulping process of ramie.

Published: May 2020

The tropical ecosystem had high biomass productivity but still less in economic values. Integrated Bio-cycle Farming System (IBFS) was an alternative system that harmoniously combines agricultural sectors (agriculture, forestry, animal husbandry, fishery, plantation estate, horticulture) and non-agricultural aspects (industry, household, infrastructure, the marketplace) on integrated ecological management. The key characteristics of IBFS developed in UGM University Farm were (i) an integration of agriculture and non-agriculture sector, (ii) value of environment, esthetics and economics, (iii) rotation and diversity of plants, (iv) artificial and functional biotechnology, (v) management of closed organic cycle, (vi) ecosystem health management, (vii) agropolitan concept, (viii) specific management of plant and (ix) holistic and integrated system. The management of cycle of energy, organic matter and carbon, water, nutrient, production, crop, money conducted through 9R (reuse, reduce, recycle, refill, replace, repair, replant, rebuild, reward) to obtain optimal benefits for global environment and livelihood. The system had a sustainable multifunction and multi-product (food, feed, fuel, fiber, fertilizer, biopharma, water, energy, oxygen, edutainment, eco-tourism). They would meet the expected basic need for daily-, monthly-, yearly- and decade’s income at short-, medium- and long- term periods. IBFS was a good prospect for sustainable economic, environmental, and socio-culture aspects.

Authors: Sihombing Adolf Leopold S.M. , Darmawan Ragil
Published: May 2020

The daily waste tonnage at Piyungan landfill is 600 tons consisting of organic and combustible waste which can be used as an energy source. The aim of this study is to determine the potential energy of waste in the Piyungan landfill by its characteristics based on technology options including landfill gas, anaerobic digestion, gasification, and incineration. The Piyungan landfill mostly contain organic waste, up to 62.1% and combustible waste (RDF) at 26.8%. Moisture content of Piyungan’s RDF is higher than international standards for RDF as raw material in several countries. The various result for Nett Calorific Value is about 7.27 MJ/kg for fresh waste, 12.78 MJ/kg for RDF, 1.74 MJ/kg for market waste and 4.14 MJ/kg for mining waste. Landfill gas can generate energy up to 1.2 MW at the beginning and reaches 2 MW during peak periods. The potential energy by using anaerobic digestion and gasification technology are 1.54 MW and 3.12 MW. By incinerate fresh waste, the potential energy can be generated up to 9 MW and 4.39 MW when incinerate RDF waste only. Calculation of potential energy can be used as a basis for selecting the right technology, especially for economic feasibility for each technology.

Published: May 2020

Postoperative rehabilitation is a cornerstone of the recovery pathway following left ventricular assist device implantation (LVAD), and patients are expected to conduct an autonomous life thanks to improved technology and increased knowledge of mechanical circulatory support. The primary purpose of the present study was to quantify clinical changes related to rehabilitation, in patients with LVAD: functional capacity, disability, and quality of life were identified as reliable outcomes to detect such changes. The current study was a scoping review conducted searching three primary databases, namely PubMed, Scopus, and Cochrane Library, from their inception until January 2020. After the selection process was completed, 12 citations were included in the present study. Three hundred eight three patients were included in the current analysis. Functional capacity, disability, and quality of life were investigated in 157, 215, 18 patients, respectively. Significant differences were found before and after rehabilitation. The mean walked distance at 6-Minute Walk Test improved from 319±96 to 412.8±86.2 metres (p<0.001), the mean score of the Functional Independence Measure from 68.4±11.8 to 92.5±10.8 points (p<0.001), the mean score of the Short Form-36 physical component from 32.7±29.9 to 55.5±24.7 points (p=0.009) and the mental component from 55.8±19.8 to 75.4±21.4 points (p=0.002). Postoperative rehabilitation is effective at improving functional capacity, disability, and quality of life in patients with left ventricular assist device; all these three domains are particularly expressive of the entity of patients’ functional recovery.

Calderón problem for Yang–Mills connections
Authors: Cekić Mihajlo
Published: May 2020

We consider the problem of identifying a unitary Yang–Mills connection

\nabla

on a Hermitian vector bundle from the Dirichlet-to-Neumann (DN) map of the connection Laplacian

\nabla^*\nabla

over compact Riemannian manifolds with boundary. We establish uniqueness of the connection up to a gauge equivalence in the case of trivial line bundles in the smooth category and for the higher rank case in the analytic category, by using geometric analysis methods.

Moreover, by using a Runge-type approximation argument along curves to recover holonomy, we are able to uniquely determine both the bundle structure and the connection. Also, we prove that the DNmap is an elliptic pseudodifferential operator of order one on the restriction of the vector bundle to the boundary, whose full symbol determines the complete Taylor series of an arbitrary connection, metric and an associated potential at the boundary.

Legislação indigenista: chefes indígenas, Antônio Vieira e a Lei de 09 de abril de 1655 no cotidiano da Amazônia portuguesa
Authors: Fernandes Fernando Roque
Published: May 2020

O processo de colonização da Amazônia Portuguesa desenvolveu-se considerando as especificidades locais. Colonos, missionários e lideranças indígenas articularam inúmeras estratégias com o intuito de monopolizar a administração da mão de obra indígena. O controle sobre os índios foi assunto de primeira ordem na administração colonial do Estado do Maranhão e Grão-Pará em meados do século XVII. Nossa proposta é apresentar um breve resumo sobre o cotidiano deste espaço que foi palco de inúmeros debates sobre a evangelização e utilização do contingente indígena. Os cenários escolhidos para tal análise foram os aldeamentos missionários da Companhia de Jesus, onde padres jesuítas e índios Principais se articulavam na tentativa de materializar projetos pessoais, institucionais e coletivos. Através das cartas missionárias, da legislação indigenista vigente à época e de documentos do Arquivo Histórico Ultramarino, analisamos o cotidiano colonial, através dos embates e alianças das diversas lideranças políticas envolvidas nesse cotidiano.

Neste artigo tenciono discutir sobre o silenciamento da mulher em uma sociedade patriarcal, da criança com deficiência em uma sociedade normatizada e pensar sobre o processo do brincar em suas relações com a educação. Como ocorreu o processo de emancipação, ou tentativa desta, em minha busca como mulher no espaço público? Como se constitui a professora tecelã de uma educação de sensibilidade e o brincar da criança com deficiência? Desse modo, sob a perspectiva metodológica da narrativa autobiográfica, busco discutir os enfrentamentos que demarcam as diferentes interfaces da mulher-professora do Atendimento Educacional Especializado. Trata-se de pesquisa em andamento, cujos resultados apontam que à criança com deficiência também brinca e se expressa num diálogo constante com o Outro.
O jongo nas comemorações do 13 de maio em São Luiz do Paraitinga
Authors: Mattos Ricardo Mendes
Published: May 2020

Nas comemorações de 13 de maio, a dança do jongo foi o principal ritual de celebração da matriz africana e mote de organização política de afro-brasileiros em São Luiz do Paraitinga. No período pós-abolição, o jongo representou um canal de comunicação do afrodescendente na sociedade republicana nascente. O desafio de incluir o liberto na cidadania republicana teve seu vórtice na roda de jongo, que passa a sofrer transformações em sua expressão cultural, de maneira a se inserir nesse novo contexto histórico. A partir da análise da cobertura da imprensa da época, de registros de cronistas e folcloristas pretende-se contribuir para a história do jongo no 13 de maio de São Luiz do Paraitinga, bem como refletir sobre a intensa mudança nessa expressão cultural quando entram na roda de jongo as contradições sociais e raciais do período de pós-abolição e da construção da cidadania republicana.

A Educação Bilíngue Intercultural como contribuição para um pensamento heterárquico
Authors: Cherñavsky Sasha Camila
Published: May 2020

Este artigo surge da reflexão sobre a Educação Intercultural Bilíngue (EIB) como uma modalidade educativa marginalizada pela educação tradicional, tendo como consequência, entre eles, o fato de serem ações realizadas de baixo de forma dispersa. Da mesma forma, essa modalidade educacional se baseia em uma lógica totalmente oposta à aplicada pela matriz colonial moderna dominante, que se torna cada vez mais discriminatória e desigual. No momento, o fim do colonialismo não está sendo vivido, mas esse fenômeno estava em mutação, mantendo assim a estrutura das relações centro-periferia no mundo e uma divisão racial do trabalho - como Quijano explica com seu conceito de colonialidade do poder. Portanto, este artigo surge da premissa de que o IBE, entre outras modalidades educativas, pode ser colocado dentro do marco do paradigma epistemológico do "Sul", transformado em prática descolonizante. Em suma, três eixos que estruturam o artigo estão implantados, no primeiro uma definição do discurso epistemológico do "Sul" é realizada, por outro lado a Educação Intercultural Bilingue é definida como uma prática descolonizante e finalmente as reflexões finais são testemunhadas.

O processo de integração sul-ame­ricano, que teve início no final do século XX, possibilitou a emergência de iniciativas de aproximação entre os países do subcontinen­te, com destaque para o MERCOSUL, a UNA­SUL e a IIRSA-COSIPLAN. Esta última gerou um importante impacto, materializado de modo especial em zonas de fronteira. Após quase duas décadas de sua criação, críticos à inicia­tiva alegam que os projetos de infraestrutura implementados caracterizam-se pela falta de participação das comunidades locais. A inob­servância dos aspectos socioambientais quan­do da execução das obras, tem efeitos negati­vos nas esferas ambiental, social, econômica e cultural. O presente trabalho trará uma análise a partir das Relações Internacionais sobre os impactos socioambientais da IIRSA-COSI­PLAN no Arco Central da fronteira brasileira. Trata-se de uma pesquisa qualitativa, pautada em análise bibliográfica.

Eslovenos online
Authors: Molek Nadia
Published: May 2020

Este artículo presenta una investigación antropológica sobre los usos de la red social Facebook entre los eslovenos en la Argentina. Los grupos de Facebook se convirtieron en una plataforma útil para reunir a migrantes eslovenos y descendientes de diferentes flujos migratorios establecidos en la Argentina en un contexto de globalización y debilitamiento del asociacionismo. Se analiza qué papel desempeña la red social Facebook en los procesos de configuración de la identidad y qué representaciones, experiencias y sentidos ―memoria/ideología― se producen y comparten en los muros de los grupos de Facebook. Algunas divisiones y representaciones de la comunidad offline aún se encuentran en el entorno virtual. Los grupos de Facebook no solo implican una herramienta de comunicación, sino también un espacio virtual que media la necesidad de los actores de configurar su propia identidad y pertenecer a una comunidad imaginada vinculada a la tierra de sus antepasados.

Comparison of the Solution of the Van der Pol Equation Using the Modified Adomian Decomposition Method and Truncated Taylor Series Method
Authors: Ndam Joel , O. Adedire
Published: May 2020

In this paper, we compare the solution of the van der Pol equation obtained by using the truncated Taylor series method and the modified Adomian decomposition method with the solution obtained by the Poincare-Lindstedt (P-L) method. The approximating 4-component modified Adomian decomposition method behaves more like an approximate P-L analytic method than the tenth-order Taylor series. Also, with the addition of just one term, the approximating 5-component modified Adomian decomposition method produces a more convergent solution to that of P-L analytic method than the twenty second-order Taylor series approximation as the independent variable t representing time progressively increases. A general comparison of the two solutions revealed that the absolute errors generated by the approximating polynomial from the Taylor series are greater than the ones generated from the modified Adomian decomposition method. It was further revealed that very few components of the modified Adomian decomposition could yield a series of about 3 times the order of the one obtained by using the Taylor series method. Hence, we recommend the inclusion of the modified Adomian Decomposition Method in modern mathematical tools.

Abstract. Because anthropogenic sulfur dioxide (SO2) emissions have decreased considerably in the last decade, PM2.5 pollution in China has been alleviated to some extent. However, the effects of reduced SO2 on the particle number concentrations and subsequent contributions of grown new particles to the cloud condensation nuclei (CCN) populations, particularly at high altitude with low aerosol number loadings, are poorly understood. In this study, we evaluated the campaign-based measurements made at the summit of Mt. Tai (1534 m a.s.l.) from 2007 to 2018. With the decrease in the SO2 mixing ratios from 15 ± 13 ppb in 2007 to 1.6 ± 1.6 ppb in 2018, the formation rate of new particles (FR) and the net maximum increase in the nucleation-mode particle number concentration (NMINP) increased by 2–3 fold in 2018 against those in 2007. In contrast, the occurrence frequency of new particle formation (NPF) events in which the maximum geometric median diameter of grown new particles (Dpgmax) was > 50 nm decreased considerably from 43 %–78 % of the NPF events before 2015 to  50 nm as a CCN threshold size at high supersaturations, the observed net CCN production decreased from 3703 cm−3 (on average) before 2015 to 1026 cm−3 (on average) in 2017–2018. We argue that the increase in the FR and NMINP is mainly determined by the availability of organic precursors that participate in nucleation and initial growth, whereas the decrease in the growth probability is caused by the reduced emissions of anthropogenic precursors. However, large uncertainties still exist because of a lack of data on the chemical composition of these smaller particles.
Ocean carbonate system variability in the North Atlantic Subpolar surface water (1993–2017)

Abstract. The North Atlantic is one of the major ocean sinks for
natural and anthropogenic atmospheric CO2. Given the variability of the
circulation, convective processes or warming–cooling recognized in the high
latitudes in this region, a better understanding of the CO2 sink
temporal variability and associated acidification needs a close inspection
of seasonal, interannual to multidecadal observations. In this study, we
investigate the evolution of CO2 uptake and ocean acidification in the
North Atlantic Subpolar Gyre (50–64∘ N) using
repeated observations collected over the last 3 decades in the framework
of the long-term monitoring program SURATLANT (SURveillance de
l'ATLANTique). Over the full period (1993–2017) pH decreases (−0.0017 yr−1) and fugacity of CO2 (fCO2) increases (+1.70 µatm yr−1). The trend of fCO2 in surface water is slightly less
than the atmospheric rate (+1.96 µatm yr−1). This is mainly
due to dissolved inorganic carbon (DIC) increase associated with the
anthropogenic signal. However, over shorter periods (4–10 years) and
depending on the season, we detect significant variability investigated in
more detail in this study. Data obtained between 1993 and 1997 suggest a
rapid increase in fCO2 in summer (up to +14 µatm yr−1)
that was driven by a significant warming and an increase in DIC for a short
period. Similar fCO2 trends are observed between 2001 and 2007 during
both summer and winter, but, without significant warming detected, these
trends are mainly explained by an increase in DIC and a decrease in
alkalinity. This also leads to a pH decrease but with contrasting trends
depending on the region and season (between −0.006 and −0.013 yr−1). Conversely, data obtained during the last decade
(2008–2017) in summer show a cooling of surface waters and an increase in
alkalinity, leading to a strong decrease in surface fCO2 (between −4.4
and −2.3 µatm yr−1; i.e., the ocean CO2 sink increases).
Surprisingly, during summer, pH increases up to +0.0052 yr−1 in the
southern subpolar gyre. Overall, our results show that, in addition to the
accumulation of anthropogenic CO2, the temporal changes in the uptake
of CO2 and ocean acidification in the North Atlantic Subpolar Gyre
present significant multiannual variability, not clearly directly associated
with the North Atlantic Oscillation (NAO). With such variability it is
uncertain to predict the near-future evolution of air–sea CO2 fluxes
and pH in this region. Thus, it is highly recommended to maintain long-term
observations to monitor these properties in the next decade.
An alternative interpretation of Peltochelys duchastelii as a paracryptodire
Authors: Joyce Walter G. , Rollot Yann
Published: May 2020

Abstract. Peltochelys duchastelii is an enigmatic turtle from Early Cretaceous (middle
Barremian–early Aptian) Sainte-Barbe Formation of Bernissart, Belgium. In more recent literature, there has been strong support for the
trionychian affinities of this taxon, but this interpretation is less
consistent with external data, in particular biogeography and temporal
considerations. We provide a reinterpretation here of the lectotype of
Peltochelys duchastelii that differs from more recent ones in key features. Although we agree that
this turtle lacks mesoplastra, we conclude that it has 11 pairs of
peripherals (not 10), likely had 12 pairs of marginals (not 11),
lacks a contact between peripheral 1 and costal 1, and that a midline
contact of peripherals 1 hinders the nuchal from contributing to the margin
of the shell. This unusual set of characters is otherwise known from roughly
coeval taxa from Europe and North America. Phylogenetic analysis yields a
previously unrecognized clade of basal paracryptodiran turtles from the Late
Jurassic to Paleogene of Euramerica united by a nuchal that is withdrawn
from the anterior margin of the shell. The name Compsemydidae is referred to this clade. The novel hypothesis suggests that Peltochelys duchastelii did not immigrate from Asia
but instead originated in Europe.
A new fossil species of Attagenus Latreille (Coleoptera: Dermestidae) in Rovno and Baltic ambers, with a brief review of known fossil beetles from the Rovno amber Lagerstätte
Authors: Bukejs Andris , Háva Jiří , Alekseev Vitalii I.
Published: May 2020

Abstract. Based on two specimens originating from Eocene Rovno and
Baltic ambers, Attagenus (Aethriostoma) gedanicissimus sp. nov. is described, illustrated and compared with the
related fossil Mesozoic species A. (Aethriostoma) turonianensis Peris et Háva, 2016. The common
beetle species for Baltic and Rovno ambers suggests the exceptional temporal
and geographical closeness of palaeoecosystems that produced both amber
deposits. An updated checklist of Coleoptera known from Rovno amber (57
species belonging to 20 families) is compiled and provided with a
bibliography of the original descriptions. The registered Rovno amber beetle
assemblage contains only eight species that also occur in Baltic amber
(14 %), while the similarity at the generic level is 56 % at the
moment. The relationship between the Rovno and Baltic amber deposits and
subjectiveness of present-day results of the beetle assemblage research are
briefly discussed (urn:lsid:zoobank.org:pub:289B5A43-C57A-4B75-8A15-6E61F4AFCD81).
