Published: November 2019

This study
was aimed to investigate the liver of red-legged partridge in regards of
morphologic and histologic features. In this
study, the liver tissues of ten red-legged partridges were removed and fixed
into 10% formaldehyde solution for 72 hours. After fixation, the liver tissues
were dehydrated through a graded alcohol series to xylene and embedded in
paraffin blocks. Obtained sections 5-7 µm thickness of sections from paraffin
blocks were stained with Crossman Modified Triple staining and examined for
histologic structures. In
morphologic examining, the liver of red-legged partridges consisted of two
lobs. In addition, histologic analysis showed that liver tissue was covered
with a thick connective tissue and this connective tissue made up of many
smaller units of liver cells called lobules. Hepatocytes were seen radially
round and located around central vena, which consists of remark cords. The
squamous cells and Kupffer cells were observed in the sinusoidal lining. In conclusion; the results from this study indicated
that there were some structural differences from other bird species, but not
functionally.

Published: November 2019

In the next seven years, the Russian economy will have to switch to digital technology and digital product. The purpose of the article is to establish general recommendations to develop and implement digital competencies. The subject of the research is the set of necessary digital competencies and their ranking. To make it easier for people to adapt to the digital economy, the authors of the article conducted a survey among the chief executives of leading enterprises in Nizhnevartovsk to predict which digital competencies need to be taken into account in professional training. In addition, the research revealed additional features that a person should possess, e.g. the information consumption culture and decisiveness. The modern Russian professional education framework is setting a new educational paradigm for students and lifelong learning. This includes fundamental changes in the professional objectives of higher education. Therefore, the training must adapt to the new contextual requirements. The article provides reflections on building a profile of digital competencies for areas of higher education training that correspond to the current context and new scenario, including those that are a cross-cutting axis for other professional competencies that become relevant in the educational domain. Our research and analysis revealed areas for the further development of digital competencies, as well as three basic principles that are crucial for the successful design and advancement of new programmes in professional education. Standardized mass education in the field of digital economy is no longer relevant. Now taxonomy defines the skills that need to be included into the digital economy through a wide range of professions. This article provides a new insight into the role of competence transition from education to the labor market. To understand today’s demand for new skills and elaborate on how it might change over the next 5-10 years, we recruited employers to identify the competencies that they consider essential.
Evolution of demand for sugar in Polan
Authors: Szajner Piotr
Published: November 2019

The accession of Poland to the EU resulted in significant changes in market regulations, and this had an important impact on the Polish sugar industry. The growth rate of demand was lower than that of production, and the sector became a net exporter. The structure of demand experienced significant changes as the consumption in households decreased, but demand is compensated for by the increased consumption in the food industry. The consumption of professional groups also varied strongly. The price increase due to EU accession, the influence of world market, and the supply fluctuations resulted in a high variability of sugar prices. The demand for sugar is characterised by low price flexibility.

Published: November 2019

Sugar beet quality analysis is an integral part of breeding and sugar beet processing and therefore contributes to the success of the beet sugar industry. This review summarizes the chronological development of important methods used for sugar beet quality analysis, with a special focus on the role that breeding companies, such as KWS, have played in establishing these methods. Finally, new technological advances are highlighted that provide possibilities to automate the analysis of quality parameters of fresh sugar beet outside of the laboratory.
Filtration of stored thick juice for the syrup campaign
Authors: Muir Barbara M. , Schöpf Stefan D. , Meade Ciara
Published: November 2019

Extraction of sucrose from sugarbeet for sugar production on an industrial scale can be divided into two distinct types of operations: beet processing (operation of the entire factory) and syrup processing (operation of the sugar house only). During the beet harvesting campaign thick juice is stored in large tanks for subsequent processing in the syrup campaign.
It is good practice to filter the thick juice prior to storage for removal of microbes and insolubles. More importantly is filtration of the thick juice during the thick juice campaign for food safety and to remove any solids that have precipitated during storage for sugar quality. This is normally done using a filter aid to ensure filtration to below 5 µm is achieved.
The use of a filter aid is not ideal due to health concerns and the risk of causing sugar quality issues if filter aid is carried forward with the syrup. A filtration system designed to operate without the use of a filter aid was therefore trialed at one of the Tereos factories in France. Standard liquor from storage tanks were filtered through 14–25 µm filter material during the 2018 thick juice campaign. Operational and sugar quality results are discussed.

Regelmäßig wird an das Institut für Zuckerrübenforschung (IfZ) herangetragen, Daten aus der Betriebsbefragung zur Produktionstechnik im Zuckerrübenanbau zur Kommunikation in verschiedene Zielgruppen zur Verfügung zu stellen. Dabei begeben sich WissenschaftlerInnen auf eine Gratwanderung zwischen zielgruppengerechter Darstellung von Ergebnissen bei Vereinfachung der Daten und Wahrung der Guten Wissenschaftlichen Praxis. Anhand der unterschiedlichen Themen Ertrag, Bodenbearbeitung, Glyphosat-Einsatz und Biodiversität werden verschiedene Darstellungsformen von Daten aus einer Betriebsbefragung gegenübergestellt und Möglichkeiten zur Kommunikation diskutiert. Es kann gezeigt werden, dass manche Themen nicht zur Vereinfachung geeignet sind und wissenschaftliche Grafiken ohne eine Einbettung in deren wissenschaftlichen Kontext zu Missinterpretationen führen können. Eine stark vereinfachte Darstellung kann bei den Konsumierenden zur Überschätzung des eigenen Wissenstandes führen. Daher ist es erforderlich, Kommunikationswege und -formen im Austausch mit Kommunikationsexperten zu konzeptionieren, um wissenschaftliche Erkenntnisse zielgruppenorientiert und sachlich einzusetzen. So kann Wissenschaft eine wesentliche Grundlage für eine fakten- und wissensbasierte gesellschaftliche Diskussion komplexer agrarwissenschaftlicher Zusammenhänge und für wissensbasierte Entscheidungen bereitstellen.
Comparison of evaporator stations with and without pre-evaporator
Authors: Lenard Piotr
Published: November 2019

Two sugar factories with a processing capacity of 6000 t/d of beet and falling film type evaporators in all effects but differing in the lay-out of the evaporator station were compared. A five-effect station with serial juice flow from effect 1 to 5 was compared with a five-effect station, where the thin juice is fed into the 4th effect (pre-evaporator), and then after additional heating to the 1st effect. For the two sugar factories identical process parameters and identical technological equipment were assumed. It was found that the use of a pre-evaporator gives significant operating benefits to the operating of the evaporation station, which may support decision of its application despite the higher installation costs compared to the station without pre-evaporator.

SZ/RT-juice purification system in Drochia – Processing of colloids separated from prelimed juice in the biogas plant of the sugar factory
Authors: Rad Mohsen Ajdari , Dandar Richard
Published: November 2019

Südzucker has installed a SZ/RT juice purification system in its Drochia factory in Moldova in 2018. The process separates the colloids precipitated in the preliming step before the main liming stage of the classical beet juice purification.
The effects on the process stability, beet slicing rate and lime stone consumption were excellent. The main liming alkalinity could be reduced and the carbonatation lime had a high dry matter and a low sugar content. The conversion of the colloid fraction to biogas in the biogas plant attached to the sugar factory was very successful. The practical experience of the last two campaigns demonstrated that it is feasible to add the colloid fraction to the pressed pulp silage. After the campaign the ensiled pulp is used as feed for the biogas plant. The process provides a carbonatation lime that is easy to press out and very low in phosphate.
Comparison of beet and cane sugar production methods and opportunities for dual production
Authors: Avram-Waganoff Pedro , Morgenroth Boris
Published: November 2019

There are still large differences in process steam consumption, sugar recovery and plant availability when comparing sugar production from beet versus that from cane on a global scale. These are partly due to higher sugar contents and purities of sugar beet, but also due to more developed process technologies enabling a more efficient usage of steam and energy. Specific areas of a cane factory that can benefit from adaption technologies typically employed in European beet sugar production are: heat-transfer equipment especially evaporators and condensers, sugar-house work including seed magma systems by cooling and improved crystallizer designs, close monitoring and reduction of water input at all stages of the process, modern layout of the plant in order to reduce pressure drops and enable good supervision, and efficient electrical drives and automation systems. As a result, the improved factories have been able to increase significantly sugar yield and cogeneration power for sale to the national grid and have an increased profitability. Some specific examples of the technological improvements and benefits obtained in some cane factories as a result of the above measures are presented. A further example of the possibilities to process sugarcane and sugar beet in a highly efficient dual-use plant is also shown. Due to the low process-steam consumption of the plant, enough surplus bagasse is produced during the cane crop in order to be self-sufficient in fuel during the beet crop.
Genome‐Wide Association Study of a Worldwide Collection of Wheat Genotypes Reveals Novel Quantitative Trait Loci for Leaf Rust Resistance

The emergence of new virulent Puccinia triticina races requires a continuous search for novel sources of resistance to combat leaf rust (LR) disease

Twenty‐two wheat genotypes resistant to four P. triticina races were identified in this study

A genome‐wide association study detected 11 quantitative trait loci for LR resistance; five of them were detected on genomic regions where no LR resistant genes have been detected.

Wheat (Triticum aestivum L.) production worldwide is being challenged by several biotic and abiotic factors. Leaf rust (LR), caused by Puccinia triticina, is a major biotic constraint of wheat production worldwide. Genetic resistance is the most efficient and cost‐effective way to control LR. Seventy‐nine LR resistance genes have been identified to date but the frequent emergence of new virulent P. triticina races every year demands a constant search for new sources of resistance with novel quantitative trait loci (QTL) or genes. The objectives of this study were to identify putative novel sources of effective resistance against the current prevalent races of P. triticina in the southeast United States and to map genomic loci associated with LR resistance via a genome‐wide association study (GWAS) approach. Evaluation of 331 diverse wheat genotypes against four prevalent P. triticina races (MFGKG, MBTNB, MCTNB, and TCRKG) revealed that the majority of the genotypes were susceptible and only 22 genotypes (6.6%) were resistant to all four P. triticina races. The GWAS detected 11 QTL on nine chromosomes for LR resistance. Of these, six QTL were identified in the vicinity of known genes or QTL; therefore, more studies are warranted to determine their relationship. Five QTL (QLr.uga‐1AL, QLr.uga‐4AS, QLu.uga‐5AS, QLr.uga‐5AL, and QLr.uga‐7AS) were identified on genomic regions where no LR resistance genes have been identified in wheat, representing potential novel loci for LR resistance. The highly resistant wheat genotypes and novel QTL reported in this study could be used in breeding programs to improve LR resistance.
Compact Star-forming Galaxies as Old Starbursts Becoming Quiescent

Optically compact star-forming galaxies (SFGs) have been proposed as immediate progenitors of quiescent galaxies, although their origin and nature are debated. Were they formed in slow secular processes or in rapid merger-driven starbursts? Answering this question would provide fundamental insight into how quenching occurs. We explore the location of the general population of galaxies with respect to fundamental star-forming and structural relations, identify compact SFGs based on their stellar core densities, and study three diagnostics of the burstiness of star formation: (1) star formation efficiency, (2) interstellar medium (ISM), and (3) radio emission. The overall distribution of galaxies in the fundamental relations points toward a smooth transition toward quiescence while galaxies grow their stellar cores, although some galaxies suddenly increase their specific star formation rate when they become compact. From their star formation efficiencies compact and extended SFGs appear similar. In relation to the ISM diagnostic, study of the CO excitation, the density of the neutral gas, and the strength of the ultraviolet radiation field shows that compact SFGs resemble galaxies located in the upper envelope of the main sequence of SFGs, although this is based on a small sample size. Regarding the radio emission diagnostic, we find that galaxies become increasingly compact as the starburst ages, implying that at least some compact SFGs are old starbursts. We suggest that compact SFGs could be starbursts winding down and eventually crossing the main sequence toward quiescence.
Abundance Ratios in GALAH DR2 and Their Implications for Nucleosynthesis
Authors: Griffith Emily , Johnson Jennifer A. , Weinberg David H.
Published: November 2019

Using a sample of 70,924 stars from the second data release of the GALAH optical spectroscopic survey, we construct median sequences of [X/Mg] versus [Mg/H] for 21 elements, separating the high-α/“low-Ia” and low-α/“high-Ia” stellar populations through cuts in [Mg/Fe]. Previous work with the near-IR APOGEE survey has shown that such sequences are nearly independent of location in the Galactic disk, implying that they are determined by stellar nucleosynthesis yields with little sensitivity to other chemical evolution aspects. The separation between the two [X/Mg] sequences indicates the relative importance of prompt and delayed enrichment mechanisms, while the sequences’ slopes indicate metallicity dependence of the yields. GALAH and APOGEE measurements agree for some of their common elements, but differ in sequence separation or metallicity trends for others. GALAH offers access to nine new elements. We infer that about 75% of solar C comes from core-collapse supernovae and 25% from delayed mechanisms. We find core-collapse fractions of 60%–80% for the Fe-peak elements Sc, Ti, Cu, and Zn, with strong metallicity dependence of the core-collapse Cu yield. For the neutron capture elements Y, Ba, and La, we infer large delayed contributions with non-monotonic metallicity dependence. The separation of the [Eu/Mg] sequences implies that at least ∼30% of Eu enrichment is delayed with respect to star formation. We compare our results to predictions of several supernova and asymptotic giant branch yield models; C, Na, K, Mn, and Ca all show discrepancies with models that could make them useful diagnostics of nucleosynthesis physics.
Predicting the Extreme Ultraviolet Radiation Environment of Exoplanets around Low-mass Stars: GJ 832, GJ 176, and GJ 436

Published: November 2019

Correct estimates of stellar extreme ultraviolet (EUV; 100–1170 Å) flux are important for studying the photochemistry and stability of exoplanet atmospheres, as EUV radiation ionizes hydrogen and contributes to the heating, expansion, and potential escape of a planet’s upper atmosphere. Contamination from interstellar hydrogen makes observing EUV emission from M stars particularly difficult, and impossible past 100 pc, and necessitates other means to predict the flux in this wavelength regime. We present EUV–infrared (100 Å–5.5 μm) synthetic spectra computed with the PHOENIX atmospheric code of three early M dwarf planet hosts: GJ 832 (M1.5 V), GJ 176 (M2.5 V), and GJ 436 (M3.5 V). These one-dimensional, semi-empirical, non-local thermodynamic equilibrium models include simple temperature prescriptions for the stellar chromosphere and transition region, from where ultraviolet (100–3008 Å) fluxes originate. We guide our models with Hubble Space Telescope far- and near-UV spectra and discuss the ability to constrain these models using Galaxy Evolution Explorer UV photometry. Our models closely reproduce the observations and predict the unobservable EUV spectrum at a wavelength resolution of <0.1 Å. The temperature profiles that best reproduce the observations for all three stars are described by nearly the same set of parameters, suggesting that early M-type stars may have similar thermal structures in their upper atmospheres. With an impending UV observation gap and the scarcity of observed EUV spectra for stars less luminous and more distant than the Sun, upper atmosphere models such as these are important for providing realistic spectra across short wavelengths and for advancing our understanding of the effects of radiation on planets orbiting M stars.
The Virgo Overdensity Explained
Authors: Donlon Thomas , Jo Newberg Heidi , Weiss Jake , Amy Paul , Thompson Jeffery
Published: November 2019

We suggest that the Virgo Overdensity of stars in the stellar halo is the result of a radial dwarf galaxy merger that we call the Virgo Radial Merger. Because the dwarf galaxy passed very near to the Galactic center, the debris has a large range of energies but nearly zero L

z
angular momentum. The debris appears to extend from 5 to 50 kpc from the Sun in the Virgo region. We connect different moving groups of this merger debris to the Perpendicular and Parallel Streams (the Virgo Stellar Stream is associated with either or both of these streams), the Hercules-Aquila Cloud, and possibly the Eridanus-Phoenix Overdensity. This radial merger can explain the majority of the observed moving groups of RR Lyrae and blue horizontal branch stars that have previously been identified in Virgo. This merger also produces debris in the solar neighborhood similar to that identified as the Gaia–Enceladus merger or Gaia sausage. Orbits are provided for components of the Virgo Radial Merger progenitor and debris that appears to be related to the Cocytos Stream, which was also recovered in the Virgo region.
An Improved Distance to NGC 4258 and Its Implications for the Hubble Constant

Published: November 2019

NGC 4258 is a critical galaxy for establishing the extragalactic distance scale and estimating the Hubble constant (

). Water masers in the nucleus of the galaxy orbit about its supermassive black hole, and very long baseline interferometric observations of their positions, velocities, and accelerations can be modeled to give a geometric estimate of the angular-diameter distance to the galaxy. We have improved the technique to obtain model parameter values, reducing both statistical and systematic uncertainties compared to previous analyses. We find the distance to NGC 4258 to be 7.576 ± 0.082 (stat.) ± 0.076 (sys.) Mpc. Using this as the sole source of calibration of the Cepheid-SN Ia distance ladder results in

km s−1 Mpc−1, and in concert with geometric distances from Milky Way parallaxes and detached eclipsing binaries in the LMC we find

km s−1 Mpc−1. The improved distance to NGC 4258 also provides a new calibration of the tip of the red giant branch of

mag, with reduced systematic errors for the determination of

compared to the LMC-based calibration, because it is measured on the same Hubble Space Telescope (HST) photometric system and through similarly low extinction as SN Ia host halos. The result is

km s−1 Mpc−1, in good agreement with the result from the Cepheid route, and there is no difference in

when using the same calibration from NGC 4258 and the same SN Ia Hubble diagram intercept to start and end both distance ladders.
A Compact Source for Quasi-periodic Pulsation in an M-class Solar Flare

Published: November 2019

Quasi-periodic pulsations (QPPs) are usually found in the light curves of solar and stellar flares; they carry the features of time characteristics and plasma emission of the flaring core, and could be used to diagnose the coronas of the Sun and remote stars. In this study, we combined the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory and the Nobeyama Radioheliograph (NoRH) to observe an M7.7 class flare that occurred at active region 11520 on 2012 July 19. A QPP was detected both in the AIA 131

bandpass and the NoRH 17

channel; it had a period of about four minutes. In the spatial distribution of Fourier power, we found that this QPP originated from a compact source and that it overlapped with the X-ray source above the loop top. The plasma emission intensities in the AIA 131

bandpass were highly correlated within this region. The source region is further segmented into stripes that oscillated with distinctive phases. Evidence in this event suggests that this QPP was likely to be generated by intermittent energy injection into the reconnection region.

BACKGROUND: Good physical and mental health of employees is one of the major characteristics of a healthy organisation.
AIM: Due to the importance of occupational burnout and its potentially negative consequences, the aim of this study was to assess occupational burnout and its related factors among Iranian nurses.
METHODS: In this cross-sectional study, 205 nurses who were working in two educational hospitals affiliated with Shahroud University of Medical Sciences were included. Forty-two of the nurses were male, and 163 were female (mean age: 31 years). Maslach Occupational Burnout Inventory, demographic and job characteristics questionnaires were completed for each nurse. Questionnaires were then collected, and data were analysed statistically by SPSS, version 22.
RESULTS: In the assessment of occupational burnout, the highest level was observed in emotional exhaustion and then in personal performance. There was a significant difference between the frequency of nurses' emotional exhaustion domain in terms of gender (P < 0.05), so that, women suffered more from emotional exhaustion. There was a significant difference between the frequencies of nurses' performance in terms of marital status (P < 0.05) so that married people had more personal performance disorder.
CONCLUSION: The results of this study showed that nurses suffered from low occupational burnout. Female gender, sleeping disorders, awakening at night and employment in stressful wards such as the emergency ward was associated with a higher level of occupational burnout in nurses.

Luttes de pouvoir, réseaux transnationaux et reconfigurations territoriales dans le Fezzan, Libye
Authors: Bensaâd Ali
Published: November 2019

Au contraire des autres régions sahariennes, le Fezzan en Libye constitue une centralité historique et symbolique mais aussi géopolitique. Centralité à l’échelle du pays mais aussi à l’échelle de la région saharo-sahélienne. Les recompositions politiques et territoriales au Fezzan et au Sahel sont fortement liées et interagissent. C’est par l’entrée des réseaux transnationaux sahéliens que nous proposons d’éclairer certaines dimensions des conflits dans cette région.

Published: November 2019

Cet entretien de 2002 de Gilles Bataillon avec Edelberto Torres-Rivas, disparu en décembre 2018, revient sur son parcours à la fois académique et militant, en montrant comment ces deux dimensions s’articulent et se croisent dans ses travaux et ses réflexions. Il évoque tour à tour l’influence que son enfance guatémaltèque a eu sur sa pensée, et l’importance du contexte politique d’alors. Il revient ensuite sur l’impact d’évènements politiques de grande magnitude comme la Révolution Cubaine. Il relate son passage par la FLACSO et la CEPAL, puis son retour en Amérique centrale et l’importance de la révolution sandiniste. Le sociologue raconte enfin son retour au Guatemala en voie de démocratisation. À la fin du conflit armé, après la signature des accords de paix, il tient un rôle important au sein de la Commission pour l’Éclaircissement Historique. Les propos rapportés ici éclairent ainsi son parcours intellectuel à la lumière de l’évolution de ses convictions et de son engagement.
Problèmes de la démocratie au Honduras
Authors: Vásquez Daniel , Robert Garance
Published: November 2019

Le présent article, à travers la description des caractéristiques du système politique hondurien, tente d’interpréter les raisons à l’origine des nombreuses crises dont le pays a été le théâtre au cours des dix dernières années, favorisant les variations des identités politiques et le développement d’options autoritaires ou néo-populistes. Prolongeant notamment les réflexions de Charles W. Anderson et de Mario Posas, le texte propose d’identifier les principaux « concurrents pour le pouvoir », leurs interactions et leurs tensions. Le système des « concurrents pour le pouvoir » est ainsi utilisé comme le modèle qui permet de déchiffrer les nombreux défis auxquels le Honduras est aujourd’hui confronté. L’article peut enfin servir de point de départ pour contextualiser le phénomène nouveau des « caravanes de migrants » et les récents conflits entre les partis politiques et les différents secteurs de la société civile organisée.
