Phylogenies are a central and indispensable tool for evolutionary and ecological research. Even though most angiosperm families are well investigated from a phylogenetic point of view, there are far less possibilities to carry out large-scale meta-analyses at order level or higher. Here, we reconstructed a large-scale dated phylogeny including nearly 1/8th of all angiosperm species, based on two plastid barcoding genes, matK (incl. trnK) and rbcL. Novel sequences were generated for several species, while the rest of the data were mined from GenBank. The resulting tree was dated using 56 angiosperm fossils as calibration points. The resulting megaphylogeny is one of the largest dated phylogenetic tree of angiosperms yet, consisting of 36,101 sampled species, representing 8,399 genera, 426 families and all orders. This novel framework will be useful for investigating different broad scale research questions in ecological and evolutionary biology.

Abstract

Objective: To investigate the effectiveness of topical anesthesia with sedation using intranasal midazolam in patients with symptomatic congenital nasolacrimal duct obstruction undergoing probing.

Patiente and Methods: In this prospective study, probing was performed with general anesthesia (30 cases) and with topical anesthesia using intranasal midazolam (0.3 mg/kg; 44 cases) in 74 patients who were divided into two groups, those 6 to 36 months old and those older than 36 months. The groups were compared after 12 to 48 months (mean, 18.2 months).

Resulte: For the patients 6 to 36 months old, the success rate was 80% in the group who received general anesthesia and 88.9% in the group who received topical anesthesia with intranasal midazolam; the difference between the two groups was not statistically significant (P > .05). For the patients older than 36 months, the success rate was 20% in the group who received general anesthesia and 25% in the group who received topical anesthesia with intranasal midazolam; there was no statistically significant difference between the two groups (P>.05).

Conclusions: Probing with topical anesthesia in the office setting is usually recommended for patients younger than 8 months. Our results show that this is suitable for children until 4 years of age with the support of intranasal midazolam sedation. Probing under topical anesthesia with intranasal midazolam is cost-effective, safe, and comparable in efficacy to probing under general anesthesia but with less risk.

Published: January 2020

ABSTRACT

Purpose: Some patients complain of a foreign body sensation, a burning sensation, or dryness after strabismus surgery. We prospectively investigated the changes in corneal and conjunctival sensitivity, tear film stability, and tear secretion after strabismus surgery.

Patiente and Methods: Corneal and conjunctival sensitivity were assessed with an esthesiometer, tear film breakup time was measured, and the Schirmer test was performed prospectively (preoperatively and 1 week, 1 month, and 3 months postoperatively) in 83 patients (124 eyes) who underwent strabismus surgery at our institution.

Resulte: There were no significant changes in corneal sensitivity, tear film stability, or tear secretion after strabismus surgery (P > .05). Conjunctival sensitivity decreased significantly after strabismus surgery (P < .05).

Conclusion: Discomfort and dryness after strabismus surgery do not seem to be related to changes in corneal sensitivity, tear film stability, or tear secretion.

Necrotizing Pseudomonas Infection of the Ocular Adnexa in an Infant With Leukocyte Adhesion Defect

To the Editors:
A 14-day-old male neonate presented with left congenital nasolacrimal duct obstruction and was prescribed topical antibiotics. One week later, he developed an ulcer over the medial canthus of the left eye. Cultures from the wound grew Pseudomonas aeruginosa. Intravenous amikacin and metronidazole were commenced. The ulcerative lesion progressively destroyed the medial upper and lower eyelids, medial canthus, and part of the left lacrimal drainage system, and extended through the maxillary antrum to cause a hard-palate perforation (Fig. 1). Intravenous meropenem was added, and topical gentamicin was increased to every 2 hours. Artificial tears and lid taping were advised. Complete blood count revealed leukocytosis. Flow cytometry analysis of the 2 integrin revealed absent surface membrane expression of CD18 on polymorphonuclear leukocytes, confirming the diagnosis of leukocyte adhesion deficiency type I.

The Regular Ground States of the Linear Boson Field in Terms of Soft Modes
Authors: Rieckers Alfred
Published: January 2020

We supplement the characterization of the regular ground states of the linear boson field, as detailed in Segal (Illinois J. Math. 6 (1962), 500–523), Weinless (J. Funct. Anal. 4 (1969), 350–379) and Baez, Segal & Zhou (Introduction to algebraic and constructive quantum field theory, Princeton University Press, 1992, Princeton), by using more developed operator algebraic methods for general Weyl systems and by continuing ideas of Honegger & Rieckers (Photons in Fock space and beyond I, World Scientific, 2015, Singapore). For a linear boson field in the sense of Segal (Illinois J. Math. 6 (1962), 500–523) the originally real symplectic test function dynamics is given in terms of a continuous unitary group. The quantized field dynamics is realized via a continuous unitary group in a representation space of the Weyl commutation relations and specifies a quasifree automorphism group, which does not act strongly continuous on the C*-Weyl algebra.

If the generator of the test function dynamics is strictly positive, we show that the quasifree dynamical automorphism group is

R

-central. Under this condition, we determine the form of
all
“partially regular” ground states, which are regular only over a subspace of test functions, introduced in Segal (Illinois J. Math. 6 (1962), 500–523).
All
regular ground states are then
functional integrals
, in some weakened sense, over the bare vacua dressed by singular classical modes. If the ground states are nuclear continuous these functional integrals are proper ones.

If there are also time-invariant test functions then the related invariant quantum modes intervene into these superpositions of the pure regular ground states and complicate particularly the fully regular case.

Global features of the sets of (partially) regular ground states are detailed and compared with the ground state sets of C*-dynamical systems. By way of example, the vacuum dressing is interpreted as a soft-boson cloud, forming collective classical soft modes.

Published: January 2020

Ihara, Kaneko and Zagier defined two regularizations of multiple zeta values and proved the regularization theorem that describes the relation between those regularizations. We show that the regularization theorem can be generalized to polynomials whose coefficients are regularizations of multiple zeta values and that specialize to symmetric multiple zeta values defined by Kaneko and Zagier.
Belize
Authors:   International Monetary Fund. Western Hemisphere Dept.
Published: January 2020

Belize’s economic recovery continues but the pace is slowing. Real
GDP grew by 3.2 percent in 2018, but recent data indicate a slowdown, reflecting a
severe drought, with growth projected to average 2 percent during 2019-20. The primary
fiscal surplus reached 2.1 percent of GDP in FY2018/19––a 4 percent of GDP rise from
two years ago––but the primary surplus is expected to narrow this year and remain
below 2 percent of GDP for the following two years. Public debt remains above 90
percent of GDP, the current account deficit is projected to remain large over the medium
term, and international reserves are just below 3 months of imports of goods and
services. The pace of structural reform has been slow. Downside risks, including from
slower U.S. growth, natural disasters, crime, and renewed pressures on correspondent
banking relationships (CBRs) could weaken growth and financial stability.

The ECF-supported program was completed successfully in March. Since then, the authorities have maintained macroeconomic stability, building on the achievements of the last years. Growth remains strong and inflation is well within the target band. However, while the fiscal stance has improved in recent years, it continues to put pressure on the external position and has not completely offset the impact of contingent liabilities on public debt, which continues to rise. Given Ghana’s history of budget cycles, the 2020 election will be a key test of the authorities’ continued commitment to fiscal discipline. Ghana is now under Post-Program Monitoring.

Published: January 2020

Abstract. Mt. Waliguan Observatory (WLG) is a World Meteorological Organization (WMO)/Global Atmosphere Watch (GAW) global baseline station in China. WLG is located at the northeastern part of the Tibetan plateau (36°17' N, 100°54' E, 3816 m a.s.l.) and has a representativeness of the pristine atmosphere over the Eurasian continent. We made long-term ground-based MAX-DOAS measurements at WLG during the years 2012–2015. In this study, we retrieve the differential slant column densities (dSCDs) and estimate the tropospheric background mixing ratios of different trace gases, including NO2, SO2, HCHO and BrO, using the measured spectra at WLG. We find averaging of 10 original spectra to be an optimum option for reducing both the statistical error of the spectral retrieval and systematic errors in the analysis. We retrieve the dSCDs of NO2, SO2, HCHO and BrO from measured spectra at different elevation angles under clear sky and low aerosol load conditions at WLG. By performing radiative transfer simulations with the model TRACY-2, we establish approximate relationships between the trace gas dSCDs at 1° elevation angle and the corresponding average tropospheric background volume mixing ratios. Mixing ratios of these trace gases in the lower troposphere over WLG are estimated to be between about 5 ppt (winter) and 70 ppt (summer) for NO2, fall below 0.5 ppb for SO2, range between about 0.3 and 0.7 ppb for HCHO, and be close to ~ 0 ppt for BrO. Our study provides valuable information and data set for further investigating tropospheric background levels of these trace gases and their relationship to anthropogenic activities.
Evaluating the surface energy partitioning in ERA5

Published: January 2020

Abstract. Climate reanalyses provide a plethora of global atmospheric and surface parameters in a consistent manner over multi-decadal time scales. Hence, they are widely-used in many fields, and an in-depth evaluation of the different variables provided by reanalyses is a necessary means to provide feedback on the quality to their users and the operational centers producing these data sets, and to help guiding their development. Recently, the European Centre for Medium Range Weather Forecast (ECMWF) released the new state-of-the-art climate reanalysis ERA5, following up on its popular predecessor ERA-Interim. Different sets of variables from ERA5 were already evaluated in a handful of studies, but so far, the quality of surface energy partitioning has not been assessed yet. Here, we evaluate the surface energy partitioning over land in ERA5, and concentrate on the appraisal of the surface latent heat flux, surface sensible heat flux, and Bowen ratio against different reference data sets and using different modelling tools. Most of our analyses point towards a better quality of surface energy partitioning in ERA5 than in ERA-Interim, which may be attributed to a better representation of land-surface processes in ERA5, and certainly to the better quality of near-surface meteorological variables. One of the key shortcomings of the reanalyses identified in our study is the overestimation of the surface latent heat flux, which – although substantially lower than in ERA-Interim – still remains in ERA5. Overall, our results indicate the high quality of the surface turbulent fluxes from ERA5 and the general improvement upon ERA-Interim, thereby endorsing the efforts of ECMWF to improve their climate reanalysis and to provide useful data to many scientific and operational fields.
RadNet 1.0: Exploring deep learning architectures for longwave radiative transfer
Authors: Liu Ying , Caballero Rodrigo , Monteiro Joy Merwin
Published: January 2020

Abstract. Simulating global and regional climate at high resolution is essential to study the effects of climate change and capture extreme events affecting human populations. To achieve this goal, the scalability of climate models and the efficiency of individual model components are both important. Radiative transfer is among the most computationally expensive components in a typical climate model. Here we attempt to model this component using a neural network. We aim to study the feasibility of replacing an explicit, physics-based computation of longwave radiative transfer by a neural network emulator, and assessing the resultant performance gains. We compare multiple neural-network architectures, including a convolutional neural network and our results suggest that the performance loss from the use of convolutional networks is not offset by gains in accuracy. We train the networks with and without noise added to the input profiles and find that adding noise improves the ability of the networks to generalise beyond the training set. Prediction of radiative heating rates using our neural network models achieve up to 370x speedup on a GTX 1080 GPU setup and 11x speedup on a Xeon CPU setup compared to the a state of the art radiative transfer library running on the same Xeon CPU. Furthermore, our neural network models yield less than 0.1 Kelvin per day mean squared error across all pressure levels. Upon introducing this component into a single column model, we find that the time evolution of the temperature and humidity profiles are physically reasonable, though the model is conservative in its prediction of heating rates in regions where the optical depth changes quickly. Differences exist in the equilibrium climate simulated when using the neural networks, which are attributed to small systematic errors that accumulate over time. Thus, we find that the accuracy of the neural network in the "offline" mode does not reflect its performance when coupled with other components.
On the value of high density rain gauge observations for small Alpine headwater catchments
Authors: Michelon Anthony , Benoit Lionel , Beria Harsh , Ceperley Natalie , Schaefli Bettina
Published: January 2020

Abstract. Spatial rainfall patterns exert a key control on the catchment scale hydrologic response. Despite recent advances in radar-based rainfall sensing, rainfall observation remains a challenge particularly in mountain environments. This paper analyzes the importance of high-density rainfall observations for a 13.4 km2 catchment located in the Swiss Alps where summer rainfall events were monitored during 3 months using a network of 12 low-cost, drop-counting rain gauges. We developed a data-based analysis framework to assess the importance of high-density rainfall observations to help constrain hydrologic processes. The framework is based on two steps, the identification of key hydro-meteorological metrics that explain the runoff coefficient and lag times (e.g. total event rainfall, center of mass of the precipitation field) and the identification of the optimal rain gauge network density to reliably reproduce the value of these metrics. The hydrological metrics are evaluated through correlation and regression analysis, resulting in the identification of three main drivers for the runoff coefficient and for runoff response lag times: the areal rainfall, the spatial asymmetry of the rainfall field and the antecedent rainfall over the three days preceding an event. The relationships between these measures and the optimal network density gives insights into the importance of reliably observing the localisation of incoming rainfall. Even at the small spatial scale of this case study, the results show that an accurate representation of the rainfall field, with at least two rain gauges, is of prime importance to understand the hydrologic response. The largely data-based analysis framework developed here is readily transferable to other settings. Given the low cost of the deployed rainfall sensor network, the approach has potential for future detailed studies in to-date sparsely observed catchments. Future work could in particular also refine the presented analysis by improving the design of the rain gauge deployment to ensure a good representation of geomorphological units and of the relative distances to the stream network.

Abstract. One of the candidate missions in the evolution of the Copernicus Space Component (CSC) is the Copernicus polaR Ice and Snow Topography ALtimeter (CRISTAL). The aim of this mission is to obtain high-resolution sea-ice thickness and land ice elevation measurements and includes the capability to determine the properties of snow cover on ice to serve Copernicus’ operational products and services of direct relevance to the Polar Regions. The evolution of the CSC is foreseen in the mid-2020s to meet priority user needs not addressed by the existing infrastructure, and to reinforce the Copernicus services by expanding the monitoring capability in the thematic domains of anthropogenic emissions (CO2), polar and agriculture/forestry/emergency. This evolution will be synergetic with the enhanced continuity of services foreseen with the next generation of the existing Copernicus Sentinels. New high-priority candidate satellite missions have been identified by the European Commission (EC) for implementation in the coming years to address gaps in current capability and emerging user needs. This paper describes the CRISTAL mission objectives, main mission requirements driving its design, the payload complement currently under development and its expected contributions to the monitoring of important components of Earth’s cryosphere.
Growth Poles and Clusters: Are There Useful Analytical Complementarities?
Authors: Vlados Charis , Chatzinikolaou Dimos
Published: January 2020

This article aims to critically review the advancements in the study of contemporary dynamics of local development under the prism of the analytical perspectives of growth poles and clusters. We proceed to a literature review of clusters and growth poles and attempt an analytical synthesis. The analysis of growth poles appears to remain within the interpretive limits of traditional economic geography, focusing mainly on the dimension of regional agglomerations. At the same time, the broader literature on clusters deals more with interdisciplinary issues in their global perspective by starting increasingly its analysis from the micro-dynamics articulated at the firm level. This article proposes a conceptual extension to the analysis of the current dynamics of local development in the framework of the “competitiveness web” that takes into account all the interdependent levels of space and actors.
Determining the Effectiveness of the Process Genre Approach in Increasing and Decreasing Saudi EFL University Students’ Complexity, Accuracy, and Fluency in Reaction Essays
Authors: Alghizzi Talal Musaed , Alshahrani Tahani Munahi
Published: January 2020

This study investigates the level of effectiveness that the process genre approach has on increasing and decreasing Saudi advanced EFL undergraduates’ Complexity, Accuracy, and Fluency (CAF) in reaction writing. Sixteen level six participants were recruited from the College of Languages and Translation at Al-Imam Muhammad Ibn Saud Islamic University. All participants undertook a pre-test and a post-test on reaction writing. After collecting 32 essays, they were analyzed based on 55 indices of CAF, and then a Wilcoxon Signed-Rank Test was applied to compare each CAF construct/sub-construct measure’s mean in the pre-test with its mean in the post-test, and between the total mean of all measures for each CAF construct/sub-construct in the pre-test with their total means in the post-test. The findings showed that there were no significant total or partial impacts of the process genre approach on participants’ reaction essay syntactic complexity, lexical density, lexical sophistication, and fluency. However, the results indicated that there were only partial effects of the approach (across some measures) on participants’ reaction essay lexical variation and accuracy. Finally, the study yields several pedagogical implications and recommendations for EFL writing instructors, educators, and researchers.
On the Viability of Energy Communities
Authors: Abada Ibrahim , Ehrenmann Andreas , Lambin Xavier
Published: January 2020

Following the development of decentralized production technologies, energy communities have become a topic of increased interest. While the potential benefits have been described, we use the framework of cooperative game theory to test the ability of such communities to adequately share the gains. Indeed, despite the potential value created by such coalitions, there is no guarantee that they will be viable: a subset of participants may find it profitable to exit the community and create another one of their own. We take the case of a neighborhood, having access to a limited resource—e.g. a shared roof or piece of land—which they can exploit if they invest in some renewable production capacity. By joining the community, participants also enjoy aggregation gains in the form of reduced network fees. We find conditions depending on the structure of renewable installation costs, on the magnitude of the aggregation effect and coordination costs and, most importantly, on the chosen sharing rule, under which the whole energy community is stable. In particular, we show that standard sharing rules often fail to enable communities to form and we suggest the adoption of slightly more sophisticated rules. Efficiency could require the intervention of a local planner or a change in network tariff structures.
The Efficiency and Distributional Effects of Alternative Residential Electricity Rate Designs
Authors: Burger Scott P. , Knittel Christopher R. , Perez-Arriaga Ignacio J. , Schneider Ian , vom Scheidt Frederik
Published: January 2020

Electricity tariffs typically charge residential users a volumetric rate that covers the bulk of energy, transmission, and distribution costs. The resulting prices, charged per unit of electricity consumed, do not reflect marginal costs and vary little across time and space. The emergence of distributed energy resources—such as solar photovoltaics and energy storage—has sparked interest among regulators and utilities in reforming electricity tariffs to enable more efficient utilization of these resources. The economic pressure to redesign electricity rates is countered by concerns of how more efficient rate structures might impact different socioeconomic groups. We analyze the bill impacts of alternative rate plans using interval metering data for more than 100,000 customers in the Chicago, Illinois area.

We combine these data with granular Census data to assess the incidence of bill changes across different socioeconomic groups. We find that low-income customers would face bill increases on average in a transition to more economically efficient electricity tariffs. However, we demonstrate that simple changes to fixed charges in two-part tariffs can mitigate these disparities while preserving all, or the vast majority, of the efficiency gains. These designs rely exclusively on observable information and could be replicated by utilities in many geographies across the U.S.
The Impact of U.S. Supply Shocks on the Global Oil Price
Authors: Gundersen Thomas S.
Published: January 2020

I examine the role of the U.S. shale oil boom in driving global oil prices. Using a structural vector autoregressive (SVAR) model that identifies separate oil supply shocks for the U.S. and OPEC, I find that U.S. supply shocks can account for up to 13% of the oil price variation over the 2003-2015 period. This is considerably more than what has been found in other studies. Moreover, while U.S. oil production has increased substantially since 2010, U.S. oil supply shocks first started to contribute negatively to oil prices beginning in late 2013. This mismatch implies a temporary friction in the transmission of U.S. supply shocks to the rest of the world likely caused by logistical and technological challenges observed in the downstream supply chain.
Passion and market: the intertwining that makes the marketization of brazilian spectacle football
Authors: Reale Getúlio Sangalli , Dalmoro Marlon
Published: January 2020

Objective: The marketization of the different social instances has pointed the market as the main intermediary of the social and cultural constructions in contemporary society, including football. Therefore, this study analyzeshow the process of marketization takes place through the intertwining between football’s cultural dimensions and the market ideology. Method: Through an interpretative approach, we perform an ethnographic study in the universe of one Brazilian football club, Sport Club Internacional.Originality/Relevance: Contributing with previous studies on consequences of the marketization process, results indicate how marketing producers and consumers naturalize passion and consumption discourses around a market ideology, shaping the marketization process.Results: We observed that both marketing producers and consumers mix the notions of ‘supporting’ and ‘consuming’ in a single discursive structure. This intertwining involves the approximation of supporters’ passion to the notion of consumer, reinforced by discourses of professionalization e the creation of new products. This process is conducted under the influence of euroamerican spectacularization of sport.Theoretical Contributions: We use the lenses of cultural and market studies to analyze a football club, demonstrating that market ideology disseminates, among other possible forms, modifying specific cultural relations, as football passion. Football marketization involves, thus, the transformation of football as a consumption cultural phenomenon mediated by economic rationality.

Published: January 2020

Do tematu wirtualnej rzeczywistości, zwanej też VR, wielu ludzi podchodzi sceptycznie. Ponadto stosunkowo niewiele osób, którym tematyka ta jest znana, przekonuje się do zastosowania nowego medium w codziennej pracy. Tekst jest próbą odpowiedzi na pytania: Jakie korzyści można czerpać z tej technologii? Czy wirtualna rzeczywistość jest nam potrzebna? Czego możemy się spodziewać po jej wejściu na rynek w przyszłości? Czy ta stosunkowo nowa technologia przetrwa próbę czasu i na stałe zagości w biurach architektonicznych? Zastosowanie VR nie ma ograniczeń, dlatego też wykorzystują ją różne dziedziny. W tekście opisano przypadki obrazujące realne zastosowania VR. Każdy z projektów jest inny ze względu na stopień zaawansowania użytej technologii. Przeanalizowane zostały projekty stworzone dla firm związanych z branżą budowlaną. Artykuł stworzono na podstawie badań własnych. Było to możliwe dzięki pracy w branży związanej z kreowaniem wirtualnej rzeczywistości. W jej trakcie przeprowadzono badania w postaci wywiadów z pracownikami firm oraz z inwestorami i osobami odwiedzającymi stanowiska z wirtualną rzeczywistością, np. podczas targów. Ponadto w badaniach wykorzystano obserwacje własne. Z badań wynika, że użycie wirtualnej rzeczywistości daje bardzo duże korzyści zarówno inwestorom, projektantom, jak i odbiorcom końcowym. Projektantom może skrócić czas pracy poprzez zintensyfikowanie procesu kreowania koncepcji. Pozwala na szybką weryfikację pomysłów i sprawdzenie ich poprawności. VR można rozpatrywać także jako świetne medium do komunikacji z klientem. Prezentacja towaru w wirtualnej rzeczywistości to także poprawa wyników sprzedaży oraz oszczędności (np. możliwość prezentowania wielu wariantów mieszkań bez konieczności fizycznego ich wznoszenia i aranżowania).

Published: January 2020

En la actualidad las amenazas hacia las infraestructuras críticas están consideradas por la UE (Unión Europea) así como por otros estamentos internacionales, uno de los riesgos más graves para la estabilidad de sus estados, afectando su disfuncionalidad gravemente a la economía y la sociedad. Ello se debe, específicamente, a que los avances constantes en las tecnologías de la información y las comunicaciones se trasladan a los Sistemas de Control Industrial (SCI).Esta asociación, Tecnologías de la Información (TI), Tecnologías de la Operación (TO), otorgan una gran flexibilidad de interconexión y expansión, gracias a su escalabilidad y a la existencia de modelos en la industria, con una conectividad cada vez más simple e intuitiva. Esta conectividad, a su vez, genera escenarios complejos con una gran cantidad de sistemas componente. El uso de las redes de comunicación hace que estos sistemas sean altamente vulnerables, ya que no fueron diseñados originalmente para este tipo de expansión o formas de comunicación. En sus orígenes fueron diseñados con el propósito principal de otorgar la máxima disponibilidad de procesos. Por lo que la disponibilidad, sigue siendo el eje fundamental a proteger en los procesos adscritos a los SCI.
En este trabajo, se presenta el sistema de conocimiento por experimentación real mediante células de automatización industrial (SICERCAI) , el cual aporta nuevas capacidades de investigación, desarrollo, simulación y banco de pruebas del funcionamiento de estos sistemas. A su vez, otorga capacidades de anticipación del comportamiento de un sistema en producción industrial y, como consecuencia directa, altas capacidades de ciberresiliencia. Con estas capacidades se consiguen recrear entornos industriales de carácter híbrido, siendo este aspecto el que más se asemeja a la realidad en la industria.
SICERCAI, proporciona capacidades estratégicas, que otorgan soluciones para focalizar los esfuerzos y así ayudar a resolver problemas complejos que se están produciendo hoy en día en los SCI.
SICERCAI suministra alternativas eficaces y eficientes para abordar la realidad de un problema planteado por la comunidad usuaria de estas células,, recreando situaciones reales, que a su vez pueden ser observadas desde puntos de vista distintos por los diferentes agentes implicados en su resolución.
Como consecuencia directa, estas perspectivas proporcionadas son admitidas, bajo un enfoque sistémico y con diferentes vías de resolución. Al ser un sistema abierto a la interconexión, SICERCAI permite la construcción de diferentes CAI con componentes de los diferentes fabricantes de tecnologías industriales, pudiéndose agregar al sistema SICERCAI para cubrir el 100% de las posibilidades arquitectónicas existentes en la industria actual. De esta manera se consigue una comprensión holística de las investigaciones llevadas a cabo mediante la utilización de SICERCAI.

I begynnelsen

Artikkelen undersøker muligheten for å la Nord-Norge og Sápmi være utgangspunktet for poetologiske refleksjoner. Med utgangspunkt i kongrastenmellom skaperkraften i Guds ord og menneskespråket knytter den an til den sere Wittgesteins forestilling om hvordan vi blir språklige. Gjennom en modifisering av visse tolkninger av Wittgenstein argumenterer artikkelen for et nært, men komplekst forhold mellom landskap og ord, et forhold som forutsetter både en instrumentell og en ikke-instrumentell bruk av språket. Gjennom lesninger av noen av diktene til den samiske dikteren Nils-Aslak Valkeapää argumenterer artikkelen for at den poietiske bruken av språket kan være det ultimate uttrykket for menneskets tilknytning til landskapet, og vice verca, at poetiske uttrykk for en slik nærhet til landskapet kan legge vesentlige føringer på hvordan vi oppfatter funksjonen til (visse former for) litteratur.
Clinical characteristics and prognostic value of MEX3A mRNA in liver cancer
Authors: Yang Dingquan , Jiao Yan , Li Yanqing , Fang Xuedong
Published: January 2020

Background

MEX3A is an RNA-binding proteins (RBPs) that promotes the proliferation, invasion, migration and viability of cancer cells. The aim of this study was to explore the clinicopathological characteristics and prognostic significance of MEX3A mRNA expression in liver cancer.

Methods

RNA-Seq and clinical data were collected from The Cancer Genome Atlas (TCGA). Boxplots were used to represent discrete variables of MEX3A. Chi-square tests were used to analyze the correlation between clinical features and MEX3A expression. Receiver operating characteristic (ROC) curves were used to confirm diagnostic ability. Independent prognostic ability and values were assessed using Kaplan–Meier curves and Cox analysis.

Results

We acquired MEX3A RNA-Seq from 50 normal liver tissues and 373 liver cancer patients along with clinical data. We found that MEX3A was up-regulated in liver cancer which increased according to histological grade (p < 0.001). MEX3A showed moderate diagnostic ability for liver cancer (AUC = 0.837). Kaplan–Meier curves and Cox analysis revealed that the high expression of MEX3A was significantly associated with poor survival (OS and RFS) (p < 0.001). Moreover, MEX3A was identified as an independent prognostic factor of liver cancer (p < 0.001).

Conclusions

MEX3A expression shows promise as an independent predictor of liver cancer prognosis.

Occupational noise has been identified to cause health hazard on workers. Noise pollution annoys, causes hearing loss, and disturbs mental capacity and performance. Noise pollution is becoming increasingly more severe in cities and occupational setting, escalating at such a high rate that it is now considered as a major threat to the quality of human lives. This study aims to evaluate the level of occupational noise exposure, the effect of noise Grain Millers and the use of personal protective equipment. The study group included 54 mill operators comprising males and females, from 38 mill shops. Age ranges from 15 to 58 years. The Noise Measurement was taken three times a day on 7 different occasions during active milling using Mini-Sound Level Meter (Risepro HT-80A). A semi-structured interviewer questionnaire was conducted to elicit some information such as the source of noise, use of hearing protective device and effect of noise on hearing. This study result indicated that noise exposure depends on types of mill operation and machines used for milling activities This study revealed that the respondents were exposed to noise pollution ranging from 85-115.90 dB(A) with average value of 102 dB(A) which is above the standard of 85 dB(A) given by NESREA.  Approximately 75% of the respondent experience temporary hearing and tinnitus shortly after work and 92.59% did not have any personal protective device or hearing protective device. Therefore, there is an urgent need for intervention and awareness on the effects of noise on health and the use of hearing protective devices should be strictly enforced by the appropriate authority.

Authors: Dölle Klaus , Zier Sandro
Published: January 2020

This study shows that spruce woodmeal can be an alternative cellulosic-based wood additive               for newsprint applications. This study used unbleached wood flour produced from Spruce  sawdust, ground and sieved to a particle size of 20-40 µm, 40-70 µm, 70-120 µm and 200-500        µm.

Woodmeal was added at levels of 2%, 4%, 6%, 8% and 10% based on oven dry fiber content. The basis weight of the newsprint handsheet manufactured was 80 g/m². The study revealed the following outcomes:

Woodmeal with a particle size distribution of 20-40 µm had the highest density followed by woodmeal with 70–150 µm, 40-70 µm, and 200-500µm. Increasing the woodmeal amount resulted in higher porosity. Woodmeal with a particle size distribution of 20-40 µm gave the lowest porosity and a particle size of 40-70 µm gave the highest porosity.

The Tensile index and burst index show decreasing values for the addition of all woodmeals and particle sizes. Woodmeal with strength additive and a particle size of 20 – 40 µm outperforms the other woodmeal types at additions of 2%, 4%, 6% and 8%. For woodmeal with a particle size of 70–150 µm at an addition of 2% and 4% an increased and similar burst index resulted for the handsheets.

First pass retention and ash retention increased for all wood flours with a maximum at 92% and 81% respectively for the wood flour with a particle size of 40-70 µm.
