Published: June 2019

Abstract. A new instrument, the High-speed Particle Phase Discriminator (PPD-HS), developed at the University of Hertfordshire, for sizing individual cloud hydrometeors and determining their phase is described herein.
PPD-HS performs an in situ analysis of the spatial intensity distribution of near-forward scattered light for individual hydrometeors yielding shape properties. Discrimination of spherical and aspherical particles is based on an analysis of the symmetry of the recorded scattering patterns.
Scattering patterns are collected onto two linear detector arrays, reducing the complete 2-D scattering pattern to scattered light intensities captured onto two linear, one-dimensional strips of light sensitive pixels.
Using this reduced scattering information, we calculate symmetry indicators that are used for particle shape and ultimately phase analysis.
This reduction of information allows for detection rates of a few hundred particles per second. Here, we present a comprehensive analysis of instrument performance using both spherical and aspherical particles generated in a well-controlled laboratory setting using a vibrating orifice aerosol generator (VOAG) and covering a size range of approximately 3–32 µm.
We use supervised machine learning to train a random forest model on the VOAG data sets that can be used to classify any particles detected by PPD-HS.
Classification results show that the PPD-HS can successfully discriminate between spherical and aspherical particles, with misclassification below 5 % for diameters >3 µm.
This phase discrimination method is subsequently applied to classify simulated cloud particles produced in a continuous flow diffusion chamber setup.
We report observations of small, near-spherical ice crystals at early stages of the ice nucleation experiments, where shape analysis fails to correctly determine the particle phase.
Nevertheless, in the case of simultaneous presence of cloud droplets and ice crystals, the introduced particle shape indicators allow for a clear distinction between these two classes, independent of optical particle size.
From our laboratory experiments we conclude that PPD-HS constitutes a powerful new instrument to size and discriminate the phase of cloud hydrometeors. The working principle of PPD-HS forms a basis for future instruments to study microphysical properties of atmospheric mixed-phase clouds that represent a major source of uncertainty in aerosol-indirect effect for future climate projections.

Abstract. We measured methane ebullition from a patterned boreal bog situated in the
Siikaneva wetland complex in southern Finland. Measurements were conducted
on water (W) and bare peat surfaces (BP) in three growing seasons (2014–2016)
using floating gas traps. The volume of the trapped gas was measured weekly,
and methane and carbon dioxide (CO2) concentrations of bubbles were
analysed from fresh bubble samples that were collected separately. We applied a mixed-effect model to quantify the effect of the environmental controlling
factors on the ebullition. Ebullition was higher from W than from BP, and more bubbles were released
from open water (OW) than from the water's edge (EW). On average, ebullition
rate was the highest in the wettest year (2016) and ranged between 0 and 253 mg m−2 d−1 with a median of 2 mg m−2 d−1, 0 and 147 mg m−2 d−1 with a median of 3 mg m−2 d−1, and 0 and 186 mg m−2 d−1 with a median of 28 mg m−2 d−1 in 2014, 2015, and 2016,
respectively. Ebullition increased together with increasing peat
temperature, weekly air temperature sum and atmospheric pressure, and
decreasing water table (WT). Methane concentration in the bubbles released
from W was 15–20 times higher than the
CO2 concentration, and from BP it was 10 times higher. The proportion of ebullition fluxes upscaled to
ecosystem level for the peak season was 2 %–8 % and 2 %–5 % of the total
flux measured with eddy covariance technique and with chambers and gas
traps, respectively. Thus, the contribution of methane ebullition from wet
non-vegetated surfaces of the bog to the total ecosystem-scale methane
emission appeared to be small.

Abstract. The Arctic Cloud Observations Using Airborne Measurements during Polar Day (ACLOUD) campaign was carried out North-West of Svalbard (Norway) between 23 May–26 June 2017. The objective of ACLOUD was to study Arctic boundary layer and mid-level clouds and their role in Arctic Amplification. Two research aircraft (Polar 5 and 6) jointly performed 22 research flights over the transition zone between open ocean and closed sea ice. Both aircraft were equipped with identical instrumentation for measurements of basic meteorological parameters, as well as for turbulent and and radiative energy fluxes. In addition, on Polar 5 active and passive remote sensing instruments were installed, while Polar 6 operated in situ instruments to characterize cloud and aerosol particles as well as trace gases. A detailed overview of the specifications, data processing, and data quality is provided here. It is shown, that the scientific analysis of the ACLOUD data benefits from the coordinated operation of both aircraft. By combining the cloud remote sensing techniques operated on Polar 5, the synergy of multiinstrument cloud retrieval is illustrated. The remote sensing methods are validated using truly collocated in situ and remote sensing observations. The data of identical instruments operated on both aircraft are merged to extend the spatial coverage of mean atmospheric quantities and turbulent and radiative flux measurement. Therefore, the data set of the ACLOUD campaign provides comprehensive in situ and remote sensing observations characterizing the cloudy Arctic atmosphere. All processed, 1 calibrated, and validated data are published in the world data center PANGAEA as instrument-separated data subsets (Ehrlich et al., 2019b, https://doi.org/10.1594/PANGAEA.902603).
A distributed simple dynamical systems approach (dS2 v1.0) for computationally efficient hydrological modelling
Authors: Buitink Joost , Melsen Lieke A. , Kirchner James W. , Teuling Adriaan J.
Published: June 2019

Abstract. In this paper, we introduce a new numerically robust distributed rainfall runoff model for computationally efficiency simulation at high (hourly) temporal resolution: the distributed simple dynamical systems (dS2) model. The model is based on the simple dynamical systems approach as proposed by Kirchner (2009), and the distributed implementation allows for spatial heterogeneity in the parameters and/or model forcing fields for instance as derived from precipitation radar data. The concept is extended with snow and routing modules, where the latter transports water from each pixel to the catchment outlet. The sensitivity function, which links changes in storage to changes in discharge, is implemented by a new 3-parameter equation that is able to represent the widely observed downward curvature in log-log space. The simplicity of the underlying concept allows the model to calculate discharge in a computationally efficient manner, even at high temporal and spatial resolution, while maintaining proven model performance at high temporal and spatial resolution. The model code is written in Python in order to be easily readable and adjustable while maintaining computational efficiency. Since this model has short run times, it allows for extended sensitivity and uncertainty studies with relatively low computational costs. A test application shows a good and constant model performance across scales ranging from 3 to over 1700 km2.
Values in water management
Authors: Mostert Erik
Published: June 2019

Abstract. Values play a key role in water management and natural resources management more generally. They can be used by individuals, groups, organisations and whole societies to judge and justify actions. In addition, they can be enacted in practice and embodied in water institutions and infrastructure. Values can be seen as responses to the necessities of human existence and the need to live together and form functioning societies. Mechanisms that can explain their origin, effects and development include reciprocity, socialisation, formal and informal sanctioning, new information, and socio‒economic change. Depending on the type of value, different measurement methods can be used, including surveys, interviews, focus groups, Q methodology, content analysis of cultural texts such as newspaper articles, argumentation analysis and participant observation. The article recommends research at the level of social groups and organisations because of the large role these play in water management. Consequently, it is important to measure their values, including both their environmental values ‒ how they relate to their environment ‒ and their social values ‒ how they relate to each other.

Abstract. The oxygen isotope composition (δ18O) of
leaf water (δ18Oleaf) is an important determinant of
environmental and physiological information found in biological archives,
but the system-scale understanding of the propagation of the δ18O of rain through soil and xylem water to δ18Oleaf
has not been verified for grassland. Here we report a unique and
comprehensive dataset of fortnightly δ18O observations in soil,
stem and leaf waters made over seven growing seasons in a temperate,
drought-prone, mixed-species grassland. Using the ecohydrology part of a
physically based, 18O-enabled soil–plant–atmosphere transfer model
(MuSICA), we evaluated our ability to predict the dynamics of δ18O in soil water, the depth of water uptake, and the effects of soil
and atmospheric moisture on 18O enrichment of leaf water (Δ18Oleaf) in this ecosystem. The model accurately predicted the
δ18O dynamics of the different ecosystem water pools,
suggesting that the model generated realistic predictions of the vertical
distribution of soil water and root water uptake dynamics. Observations and
model predictions indicated that water uptake occurred predominantly from
shallow (<20 cm) soil depths throughout dry and wet periods in all years, presumably due (at least in part) to the effects of high grazing
pressure on root system turnover and placement. Δ18Oleaf
responded to both soil and atmospheric moisture contents and was best
described in terms of constant proportions of unenriched and evaporatively
enriched water (two-pool model). The good agreement between model
predictions and observations is remarkable as model parameters describing
the relevant physical features or functional relationships of soil and
vegetation were held constant with one single value for the entire
mixed-species ecosystem.
Modernidad y crisis de valores en "El Edificio Yacobián": El lugar de Alaa Al Aswany en el campo literario egipcio
Authors: Becerra González Fabián
Published: June 2019

En diálogo con la tradición novelística de Medio Oriente, el artículo aborda la introducción al campo literario del escritor egipcio Alaa Al Aswany, quien en El Edificio Yacobián (2002) sienta una toma de posición ante los discursos oficiales preponderantes en su sociedad a finales del siglo XX y comienzos del XXI.

En primer lugar, se contextualiza la historia literaria de la región, comprendida como un escenario de pugnas entre agentes e instituciones que, a partir de una conciencia nacional emergente, abarcaron la noción de identidad a través del género novelesco; esto, como antecedente imprescindible para advertir la irrupción y problematización del autor. Finalmente, se pretende desenvolver el planteamiento de axiologías opuestas que consolidan la construcción de la propuesta literaria, a través de personajes que encarnan actitudes y modos de ser propios del intervalo comprendido entre el ascenso del naserismo y la Guerra del Golfo; fenómenos relevantes para Aswany, quien se inserta en la literatura contemporánea actualizando episodios determinantes en la historia de Egipto.

The Winning of Tom Joad: Steinbeck's Refutation of the Western Romance in The Grapes of Wrath
Authors: Entze Jerry
Published: June 2019

Harold Bell Wright, an immensely popular author of the early twentieth century, is best known for his westerns such as The Shepherd of the Hills. His target audience was the working class, those who read for escape before the advent of radio and television. Wright's novel The Winning of Barbara Worth is mentioned in The Grapes of Wrath. The Joads are prime examples of Wright's primary audience. Steinbeck recognized this and the reference to Wright makes this clear. A further examination of Barbara Worth reveals that Steinbeck addresses several similar themes in The Grapes of Wrath. Most apparent is the struggle between the common people and big business or capitalism, along with the importance of the land, and pride in one's heritage. Steinbeck takes the themes Wright used for dramatic tension and reveals how they directly affected the people who read Wright's novels.

The U.S. Fracking Boom: Impact on Oil Prices
Authors: Frondel Manuel , Horvath Marco
Published: June 2019

As of late 2008, the steady decline of U.S. crude oil production over the last decades was reversed by the increased adoption of the hydraulic fracturing (“fracking”) technology. Adapting the supply-side model proposed by Kaufmann et al. (2004) to assess OPEC’s ability to influence real oil prices, this paper investigates the effect of the increase in U.S. oil production due to fracking on world oil prices. Among our key results obtained from (dynamic) OLS estimations, there is a statistically significant negative long-run relationship between increased U.S. oil production and oil prices.

Probability-Possibility Theories Based Iris Biometric Recognition System
Authors: Majd Bellaaj
Published: June 2019

The performance and robustness of the iris-based recognition systems still suffer from imperfection in the biometric information. This paper makes an attempt to address these imperfections and deals with important problem for real system. We proposed a new method for iris recognition system based on uncertainty theories to treat imperfection iris feature. Several factors cause different types of degradation in iris data such as the poor quality of the acquired pictures, the partial occlusion of the iris region due to light spots, or lenses, eyeglasses, hair or eyelids, and adverse illumination and/or contrast. All of these factors are open problems in the field of iris recognition and affect the performance of iris segmentation, its feature extraction or decision making process, and appear as imperfections in the extracted iris feature. The aim of our experiments is to model the variability and ambiguity in the iris data with the uncertainty theories. This paper illustrates the importance of the use of this theory for modeling or/and treating encountered imperfections. Several comparative experiments are conducted on two subsets of the CASIA-V4 iris image database namely Interval and Synthetic. Compared to a typical iris recognition system relying on the uncertainty theories, experimental results show that our proposed model improves the iris recognition system in terms of Equal Error Rates (EER), Area Under the receiver operating characteristics Curve (AUC) and Accuracy Recognition Rate (ARR) statistics.

IMAGE MANAGEMENT OF POLITICIANS ON FACEBOOK AND CITIZENS’ ELECTORAL ACTIVITY
Authors: Dudek Krystian
Published: June 2019

The functioning of politicians in the public space is connected with the necessity of building and managing the image, presenting opinions, views, reporting activities and building relations with the electorate in order to mobilise it to electoral activity. The key to success is to reach voters effectively. Among many communication tools available, the importance of the Internet and social media in particular is constantly growing. It takes over other communication channels’ functions and enables direct contact with the voter. However, in order to use the potential of the most popular social media in Poland – Facebook – and effectively manage the image, one needs to know its character and rules governing this environment. Unfortunately, politicians’ knowledge on this subject proves to be rather poor, which translates into the quality of their communication with voters. Research has proved that politicians who know how to use this tool achieve much greater reaches (regardless of the number of those entitled to vote) and build stronger relationships with voters, which translates into the electorate’s behavior during the elections.

Published: June 2019

This paper seeks to understand the marketing roles in studies on universities to market technology transfer processes and relies on the fact that universities play a key role in the technological development of a nation. To this end, a systematic review was performed from the Web of Science portal, which generated as a result forty articles. It was found that no periodic dedicated to the marketing item presented on the subject, as well as any of the articles was evaluated based on the marketing theories. Thus, gaps have been identified for research in marketing in this context as well, pointing to negligence of marketing researchers in a theme as relevant for today's world. As an essential consideration, it was found that marketing can contribute to the improvement process of practices that foster innovation in universities in various ways, as in understanding the internal relationships in the institutions, in partnership with these institutions internal and external actors, in promoting technologies and the development of channels with the market, the performance of the developed actions and their results, among other aspects.

The use of lean production in organizations, which aims to broaden your results using fewer resources, that is, to increase productivity producing essentially necessary and eliminating what does not add value to clients, requires actions that include mapping of success environments and organization's readiness for change management. Hence we have the current case study, descriptive, which presents the implementation of lean manufacturing in the textile plant in Blumenau (Santa Catarina) that manufactures medical products from a company with three manufacturing units. Next, there were interviews with thirteen managers and staff who participated in the lean manufacturing implementation process in the unit in focus. As a result, we identified that the requirements and preparations for the deployment mentioned are directed to a behavioral change that includes preparation of leadership, aligned with the organization's strategy, which needs to be deployed to all areas. Also featured are the stages of implementation and attempts to institutionalize the environment provided by the principles of lean manufacturing. It concludes with the identification of categories of analysis for the changes arising from the aforementioned deployment.

Published: June 2019

O presente projeto propôs uma avaliação das condições da superfície do pavimento flexível da rodovia TO-255, trecho de Porto Nacional a Monte do Carmo – TO, contabilizando 39,1 quilômetros. Para realizar a pesquisa aplicou-se o método de avaliação superficial de pavimento flexível denominado Levantamento Visual Contínuo - LVC, desenvolvido pelo DNIT e regido pela norma 008/2003 – PRO na qual informa as condições necessárias para a realização do método, que ocorre a partir de visitas in loco para identificar as principais patologias do trecho. O método baseia-se na verificação do estado geral da superfície asfáltica e das manifestações patológicas nela presentes, resultando-se em 03 (três) índices que são: ICPF (Índice de Condição de Pavimentos Flexíveis), IGGE (Índice de Gravidade Global Expedito) e o IES (Índice do Estado de Superfície do Pavimento). Foram analisados quarenta subtrechos com extensão de um quilômetro cada, e através dessa pesquisa foi possível classificar o estado de conservação do pavimento atual como ótimo, bom, regular, ruim e péssimo, bem como a frequência das patologias identificadas no seguimento. Á partir dessa análise é evidenciada a importância de planejamentos que envolvam medidas de conservação e prevenção sobre o pavimento, evitando o agravamento das condições da via, possibilitando assim um gerenciamento consciente e eficaz.
Peritoneal Tuberculosis Presenting as Chronic Ascites With Scrofula: A Case Report
Authors: Bogoslovskaya Galina , Zaldivar Jose
Published: June 2019

Peritoneal tuberculosis (PTB) is a common type of extrapulmonary tuberculosis; however, due to variety of clinical presentations, diagnostic challenges do occur. The nonspecific features of this disease can lead to diagnostic delays and the development of complications. In addition, PTB can mimic a malignancy, especially in women who present with ascites and elevated cancer antigen (CA) 125 levels. A high index of suspicion is an important factor in an early diagnosis. Moreover, an early diagnosis and the initiation of antituberculous therapy are essential for preventing morbidity and mortality. Fortunately, most of these patients respond very well to standard antituberculous therapy.Here, we have reported the case of a young female patient who presented with chronic ascites, mild abdominal tenderness, and later, scrofula. Ultimately, she was diagnosed with PTB based on her test results. We expect that this case report will contribute to the existing literature on this subject.
Improving the quality of low SNR images using high SNR images
Authors: Xie Yaohua
Published: June 2019

It is important to get data with Signal-Noise-Ratios (SNR) as high as possible. Compared to other techniques, filtering methods are fast. But they do not make full use of the characteristics of sample structure which reflected by relevant high SNR images. In this study, we propose a technique termed “TransFiltering”. It transplants the characteristics of a high SNR image to the frequency spectrum of a low SNR image by filtering. Usually, the high SNR and the low SNR image should have similar structure pattern. For example, they all come from the same image sequence. In the proposed method, Fourier transform is first performed on both of the images. Then, the frequency spectrum of the low SNR image is filtered according to that of the high SNR image. Finally, inverse Fourier transform is performed to get the image with improved SNR. Experiment results show that the proposed method is both effective and efficient.
2018 YPIC Challenge: A case study in characterizing an unknown protein sample
Authors: Pino Lindsay , Lin Andy , Bittremieux Wout
Published: June 2019

For the 2018 YPIC Challenge contestants were invited to try to decipher two unknown English questions encoded by a synthetic protein expressed in Escherichia coli. In addition to deciphering the sentence, contestants were asked to determine the 3D structure and determine any post-translation modifications left by the host organism. We present how we analyzed this unknown sample using a tryptic digest with dynamic exclusion disabled to increase the signal-to-noise ratio of the measured molecules. Subsequently, spectral clustering was used to generate high-quality consensus spectra and condense the acquired MS/MS spectral data. De novo spectrum identification was used to determine the English questions encoded by the synthetic protein, and any post-translational modifications introduced by E. coli on the synthetic protein were detected using spectral networking. Although the synthetic protein sample for the 2018 YPIC Challenge is not of biological interest, the experimental and computational strategy presented here can be directly used to analyze samples for which no protein sequence information is available or when the identity of the sample is unknown. All software and code to perform the bioinformatics analysis is available as open source, and a self-contained Jupyter notebook is provided to fully recreate the analysis.

Published: June 2019

The increase in greenhouse gases with high global warming potential such as methane is a matter of concern and requires multifaceted efforts to reduce its emission and increase its mitigation from the environment. Microbes such as methanotrophs can assist in methane mitigation. To understand the metabolic capabilities of methanotrophs, a complete genome-scale metabolic model (GSMM) of an obligate methanotroph,Methylococcus capsulatusstr. Bath was reconstructed. The model contains 535 genes, 899 reactions and 865 metabolites and is namediMC535. The predictive potential of the model was validated using previously-reported experimental data. The model predicted the Entner–Duodoroff pathway to be essential for the growth of this bacterium, whereas the Embden–Meyerhof–Parnas pathway was found non-essential. The performance of the model was simulated on various carbon and nitrogen sources and found thatM. capsulatuscan grow on amino acids. The analysis of network topology of the model identified that six amino acids were in the top-ranked metabolic hubs. Using flux balance analysis, 29% of the metabolic genes were predicted to be essential, and 76 double knockout combinations involving 92 unique genes were predicted to be lethal. In conclusion, we have reconstructed a GSMM of a methanotrophMethylococcus capsulatusstr. Bath. This is the first high quality GSMM of a Methylococcus strain which can serve as an important resource for further strain-specific models of the Methylococcus genus, as well as identifying the biotechnological potential ofM. capsulatusBath.
