AbstractThe antibacterial activity of honeys derived from the endemic flora of the southwest corner of Western Australia, including the trees Jarrah (Eucalyptus marginata) and Marri (Corymbia calophylla), remains largely unexplored. Investigation of these honeys showed minimum inhibitory concentrations (MICs) of 6.7–28.0% (w/v) against Gram positive and negative bacteria. Honey solutions showed enhanced antibacterial activity after hydrogen peroxide was allowed to accumulate prior to testing, with a mean MIC after accumulation of 14.3% compared to 17.4% before accumulation. Antibacterial activity was reduced after treatment with catalase enzyme, with a mean MIC of 29.4% with catalase compared to 15.2% without catalase. Tests investigating the role of the Gram negative outer membrane in honey susceptibility revealed increases in activity after destabilisation of the outer membrane. Honeys reduced both the formation of biofilm and the production of bacterial pigments, which are both regulated by quorum sensing. However, these reductions were closely correlated with global growth inhibition. Honey applied to existing biofilms resulted in decreased metabolic activity and minor decreases in viability. These results enhance our understanding of the mechanisms of antibacterial action of Jarrah and Marri honeys, and provide further support for the use of honey in the treatment of infected wounds.
Lateral variability of ichnological content in muddy contourites: Weak bottom currents affecting organisms’ behavior

Published: November 2019

AbstractAlthough bioturbation is commonly recognized in contourites, only a few studies have analyzed the ichnological content of these deposits in detail. These studies have mainly focused on meso-scale bigradational sequence (a coarsening upward followed by a fining-upward sequence resulting from variations in current velocity). Here we present data from gravitational cores collected along the NW Iberian Margin showing systematic variation in ichnological content across proximal to distal depocenters within a large-scale elongated contourite drift. Data demonstrate that tracemakers’ behavior varies depending on the distance relative to the bottom current core. Trace fossils are already known to be a useful tool for studying of contouritic deposits and are even used as criterion for differentiating associated facies (e.g., turbidites, debrites), though not without controversy. We propose a mechanism by which the distance to the bottom current core exerts tangible influence on specific macro-benthic tracemaker communities in contourite deposits. This parameter itself reflects other bottom current features, such as hydrodynamic energy, grain size, nutrient transport, etc. Ichnological analysis can thus resolve cryptic features of contourite drift depositional settings.

AbstractSpittlebugs (Hemiptera: Aphrophoridae) are the dominant xylem-sap feeders in the Mediterranean area and the only proven vectors of Xylella fastidiosa ST53, the causal agent of the olive dieback epidemic in Apulia, Italy. We have investigated the structured population phenology, abundance and seasonal movement between crops and wild plant species of both the nymphal and adult stages of different spittlebug species in olive groves. Field surveys were conducted during the 2016–2018 period in four olive orchards located in coastal and inland areas in the Apulia and Liguria regions in Italy. The nymphal population in the herbaceous cover was estimated using quadrat samplings. Adults were collected through sweep nets on three different vegetational components: herbaceous cover, olive canopy and wild woody plants. Philaenus spumarius was the most abundant species; its nymphs were collected from early March and reached a peak around mid-April, when the 4th instar was prevalent. Spittlebug adults were collected from late April until late autumn. P. spumarius adults were abundant on the herbaceous cover and olive trees in late spring, and they then dispersed to wild woody hosts during the summer and returned to the olive groves in autumn when searching for oviposition sites in the herbaceous cover. A relatively high abundance of P. spumarius was observed on olive trees during summer in the Liguria Region. The present work provides a large amount of data on the life cycle of spittlebugs within an olive agroecosystem that can be used to design effective control programmes against these vectors in infected areas and to assess the risk of the establishment and spread of X. fastidiosa to Xylella-free areas.
Corona lightning overvoltage analysis for a 500 kV hybrid line
Authors: Said Abdelrahman , Anane Zahira 
Published: November 2019

In this paper, the overvoltage distributions due to the lightning stroke are analyzed for a 500 kV hybrid OHTL‐Cable‐GIL circuit beside substation, in which the section length is variable. Corona effect is incorporating in order to estimate the attenuation and deformation of overvoltage's travelling waves on transmission lines near substations. The influence of connecting substations surge arrester, direct, and indirect lightning strokes are investigated. ATP/Electro Magnetic Transients Program(EMTP) simulation program is applied to analyze the lightning overvoltage of a 500 kV hybrid OHTL‐Cable‐GIL system. It was discovered that OHTL‐Cable, OHTL‐GIL, and hybrid systems produces lightning overvoltages higher than those of a fully cable system and very likely lower than those of a fully OHTL system with the same transmission lengths. This means that the risk of experiencing high lightning overvoltages and stressing system components is higher in a fully‐Overhead Line (OHL)circuit than in a partial or full cable or GIL line. Furthermore, using the Cable with MOSA (Metal Oxide Surge Arrester), the results have more regular voltage waveform at substation entrance; also Hybrid line has the same effect of fully GIL. Finally, the corona has a less attenuation effect of overvoltage reached to substation by about 2.7% in case short length OHTL.

Zusammenfassung
Fragestellung Ziel unserer Studie war die Analyse der Effektivität von intravitrealen Injektionen mit Aflibercept. Ein weiterer Untersuchungsgegenstand waren mögliche negative Einflussfaktoren auf die Behandlung von PatientInnen mit therapienaiver exsudativer Makuladegeneration.
Methode Es wurden Real-Life-Daten von PatientInnen mit exsudativer altersbedingter Makuladegeneration (nAMD) unter Aflibercept-Therapie retrospektiv erhoben. Erfasst wurden u. a. Geschlecht, Alter, Entfernung zur Klinik in km, Art des Transports, bestkorrigierter Visus (BCVA), zentrale Foveadicke (CFT) bei Diagnosestellung und allen Verlaufskontrollen, Sehbehinderung nach WHO-Kriterien, Anzahl der Kontrollen und Anzahl der Injektion im 1. Jahr sowie im 2. Jahr nach Behandlungsbeginn.
Ergebnisse Es wurden Daten von 483 PatientInnen erhoben. Die PatientInnen erhielten in den ersten 12 Monaten 4,91 ± 1,9 Injektionen und nach 26 Monaten 7,06 ± 3,6 Injektionen. Nach der initialen Loading Dose steigerte sich der BCVA signifikant von 0,72 logMAR (± 0,44) auf 0,63 logMAR (± 0,45; p = 0,03), jedoch kam es bis zum Ende des Beobachtungszeitraums zu einem signifikant schlechteren Visus als zu Behandlungsbeginn (0,82 logMAR ± 0,48; p < 0,01). In einer Trendanalyse zeigte sich mit weiterer Entfernung des Wohnorts zur Klinik ein signifikant höherer Anteil der PatientInnen, die einen Krankentransport oder eine Begleitung aus dem privaten Umfeld benötigten. Außerdem war in Korrelation mit der Distanz zur Klinik ein signifikanter Anstieg höhergradiger Sehbehinderungen feststellbar (beides p < 0,001).
Schlussfolgerung Die Real-Life-Daten therapienaiver PatientInnen mit exsudativer AMD unter Aflibercept-Therapie zeigen, dass im Vergleich zu randomisierten klinischen Studien ein schlechteres Visusergebnis und eine niedrigere Injektionsfrequenz erzielt wurde. Der höhere Bedarf für einen begleitenden Patiententransport und der Anstieg der Prävalenz höhergradiger Sehbehinderungen bei zunehmender Entfernung des Wohnorts zur Klinik könnten einen Hinweis auf strukturelle Probleme der Versorgungsqualität von PatientInnen mit nAMD darstellen.

Hypoglykämien und Gehirn
Authors: Frank Erbguth 
Published: November 2019

ZUSAMMENFASSUNGAufgrund seiner energetischen Abhängigkeit von der direkten Glukosezufuhr ist das menschliche Gehirn gegenüber Hypoglykämien sehr vulnerabel. Schwere Hypoglykämien führen zu Bewusstseinsstörungen, schlaganfallähnlichen fokalen motorischen Symptomen und Krampfanfällen. Akute Funktionsstörungen können bei schwerer hypoglykämischer Exposition in irreversible neuronale Zellschädigungen übergehen. Zerebrale Regulationsmechanismen tragen nach rezidivierenden Hypoglykämien zur Ausbildung einer Hypoglykämie-Wahrnehmungsstörung bei, die das Risiko schwerer Hypoglykämien weiter erhöht. Bei Typ-1-Diabetespatienten konnten bis ins mittlere Lebensalter keine negativen kognitiven Auswirkungen vermehrter Hypoglykämien bewiesen werden, allerdings ist offen, ob sich diese möglicherweise erst in höherem Lebensalter manifestieren. Bei Typ-2-Diabetespatienten bestehen bi- oder sogar tridirektionale kausale Zusammenhänge zwischen eingeschränkter Kognition, Hypoglykämien und einer schlechten glykämischen Kontrolle.

Published: November 2019

Background Iatrogenic Type A aortic dissection (IAD) is a rare but devastating complication of cardiac and aortic surgery with reported operative mortality of 30 to 50%. In this study, we report our experience with IAD and propose a standardized approach to management.
Methods From January 1, 2000 through December 31, 2016, 23,275 patients underwent cardiac surgery at our institution. We identified 15 patients who developed IAD. Our approach to management included (1) immediate repair, (2) involvement of a second attending surgeon, (3) aggressive monitoring of malperfusion, (4) securing true lumen arterial perfusion access and systemic cooling, and (5) performance of hemiarch or total arch replacement based on the presence of suspected brain malperfusion. The index operation was also completed at the same time. Patient preoperative characteristics, operative sequence and technique, complications, and outcomes were analyzed with chart review.
Results The incidence of IAD at our institution was 0.06% (n = 15). A disproportionate percentage of patients had aneurysmal ascending aortas (33.3%). The index surgery consisted of aortic surgery in five patients (33.3%), coronary bypass in three patients, valve surgery in five patients, and transplantation in one patient. The mechanism of dissection was aortic cannulation in 66.7% and aortic root vent site cannulation in 13.3%. In 46.7% of patients, the IAD was first recognized based on clinical evidence such as aortic hematoma, pericardial bleeding, or abnormal perfusion line pressures. In 40.0%, the diagnosis was made with intraoperative echocardiography without any clinical manifestations. The timing of the diagnosis was at the initiation of cardiopulmonary bypass initiation in 60.0%, while in 40.0% it was recognized after discontinuation of bypass. Hemiarch was done in 73.3% and total arch replacement performed in 13.3%. Isolated ascending repairs were done in two patients. Bypass and cross-clamp times were 229.5 ± 212.7 minutes and 130.5 ± 109.5 minutes, respectively. In-hospital mortality in our cohort was 6.7%. While stroke occurred in one patient, no visceral organ malperfusion was recognized.
Conclusions Incidence of IAD is low with cannulation of an aneurysmal aorta being a risk factor. A standardized approach may result in reduced operative mortality.
Quantum eigenvalue estimation via time series analysis
Authors: Somma Rolando D 
Published: November 2019

Abstract
We present an efficient method for estimating the eigenvalues of a Hamiltonian H from the expectation values of the evolution operator for various times. For a given quantum state ρ, our method outputs a list of eigenvalue estimates and approximate probabilities. Each probability depends on the support of ρ in those eigenstates of H associated with eigenvalues within an arbitrarily small range. The complexity of our method is polynomial in the inverse of a given precision parameter ϵ, which is the gap between eigenvalue estimates. Unlike the well-known quantum phase estimation algorithm that uses the quantum Fourier transform, our method does not require large ancillary systems, large sequences of controlled operations, or preserving coherence between experiments, and is therefore more attractive for near-term applications. The output of our method can be used to estimate spectral properties of H and other expectation values efficiently, within additive error proportional to ϵ.

Abstract
The article presents an analysis of the results of diagnostic studies on cattle leukemia in the Irkutsk region for 2004-2017. It has been established that infection with the cattle leukemia virus was 3.7 ± 0.4%; the number of hematological sick animals was 4.2 ± 0.2%. During the analyzed period, the percentage of infected livestock decreased (p <0.01) in both public and individual sectors. The number of hematological animals ranged from 2.3 to 6.1% (with peaks in 2007 and 2015) and was characterized by a slight decrease (by 0.9%).
Agroecological substantiation of the sustainable development of arable soil fertility of the Altai dry steppe
Authors: Кudryavcev A , Stetsov G , Toropova E 
Published: November 2019

Abstract
The soil resources of the Altai dry steppe (and their fertility in particular) degrade in their evolutionary anthropogenic development. Transformation of fertility is occurring due to a combination of phenomena, such as natural conditions, intensive use, farming system practiced in the absence of science-based regimes. It is established that the humus content and humus horizon thickness are statistically significantly reduced due to the activation of deflation and dehumification processes. More than that, areas of alkaline soils are increasing. The authors also point out to the degrading granulometric composition. Also, the amount of physical clay, silt fractions, cation exchange capacity, exchangeable calcium, potassium, and mobile phosphorus decreases. Statistical processing of fertility parameters of allowed us to develop a scale of process dynamism and establish the degree of dynamism in the considered soil properties, as well as to assess the rate of increasing adverse changes or their absence. Intensity of degradation processes and indicators determining it contributed to the development of levels of agro-ecological state, such as “Norma”, “Risk”, “Krizis” and “Bedstviye” (based on GIS).

Published: November 2019

Abstract
The article presents a technique of taking a genetic material from a postmortem material of appendage and testes of sables, conducted research to determine the mobility of sperms, morphological assessment and survival of sperms outside the animal body. When introducing artificial insemination in the sable industry, the use of post-mortem genetic material obtained from male sables is a promising direction in the reproduction of sable as a particularly valuable commercial species, as well as for its introduction into the zoo culture in order to ensure the biodiversity of natural systems where these animals live. It can also be used in the development of programs for the reproduction and conservation of populations of other particularly valuable, rare, and endangered species of mammals.

Published: November 2019

Abstract
The article presents an information-logical model of the dependence of the productivity of onion on certain meteorological and soil-physical factors. The authors conclude that meteorological factors of the growing season have a great influence on crop production, namely the hydrothermal coefficient and the sum of temperatures. Soil-physical factors (humidity and volumetric heat capacity) are also highly important.
Present climate development in Southern Siberia: a 55-year weather observations record
Authors: Kharlamova N , Sukhova M , Chlachula J 
Published: November 2019

Abstract
Siberia is a key region for study of the climate development in north-central Eurasia in terms of global climatic change. The relief creates a major orographic barrier for atmospheric streams influencing the regional altitudinal weather zonality. Systematic 55-year (1963-2017) weather observations along the 700 km N-S latitudinal transect across the southern Siberian plains and the adjoining ranges of the Altai-Sayan Mountains document progressing seasonal temperature and humidity shifts. Standard meteorological data from twenty meteorological stations in different topographical and natural settings with specific weather conditions document a rise of a regional atmospheric humidity balance reflected by the increased bulk annual precipitation rates in the mountain areas accompanied by pronounced seasonal air-temperature fluctuations. This regionally trend provides evidence speaking in favor of the strengthening climate continentality over Siberia, which is also manifested by the pronounced seasonal temperature regime with increased thermally positive and negative air temperature anomalies. A landscape response to a climate warming is particularly evident in the high mountain zone. The present thermal conditions with raised MAT contribute to the progressing melting of mountain glaciers and degradation of permafrost in the alpine zone, as well as aridization of the parkland-steppe areas that are being partly transformed into continental semi-arid to deserted steppes. The associated environmental transformations trigger shifts in the local biotopes and ecosystems, with an altitudinal expansion of taiga-forest into the alpine tundra belt and xerothermic grassland invasions in the foothills. The modern climate changes have a major bearing to the Altai-Sayans socio-economic development.

Published: November 2019

Abstract
The article is devoted to the study of the possibility of using natural zeolites as adsorbents for the purification of unrefined vegetable oils, intended for direct consumption in food, from undesirable concomitant substances. To increase their sorption capacity, various activation methods were used, such as physical and chemical. The best sorption properties were found in zeolites, activated by the complex method (heat and acid treatment). Conducted refining of unrefined sunflower oil allowed to increase its quality to meet the requirements of the state standard for the highest grade oil.
