Abstract

Background
To the best of our knowledge, up to now, there are no reports on the antioxidant activity of phenolic compounds of Crataegus oxyacantha flowers and fruits. Such detailed information is essential to advance the existing knowledge and to promote the use of this species growing in Africa.
Therefore, the objective of this investigation was to analyze the content of phenolic compounds as well as the antioxidant activities of flowers and fruits of C. oxyacantha from Bejaia (Northeastern Algeria) by different analytical methods, and to determine the relationship between them.

Methods
Phenolic compounds and antioxidant activity of Algerian hawthorn flowers and fruits (C. oxyacantha L.) were studied. Total phenolics, flavonoids and flavonols were determined using colorimetric methods. The phenolic profile was analyzed by high-performance liquid chromatography with diode array detection, and the in vitro antioxidant activity was measured using scavenging assay (FRAP) and Fremy’s salt, using electronic paramagnetic resonance.

Results
Different classes of phenolic compounds were identified and quantified. Hawthorn flowers contained higher levels of hydroxycinnamic acids, vitexin derivatives and flavonols compared to fruits, while anthocyanins were present only in fruits. Significant correlations were found between phenolic content and antioxidant activity. The results also showed that although the phenolic content of the two parts was different, their antioxidant capacity was not statistically different.

Conclusions
The results of this study indicate that hawthorn flowers and fruits of C. oxyacantha may be considered as a natural source of bioactive compounds.

Abstract

Prochlorococcus marinus MIT 9303 is a marine cyanobacterium found in sea waters. It was first isolated from a depth of 100 m in the Sargasso Sea in the year 1992. This cyanobacterium serves as a good model system for scientific research due to the presence of many desirable characteristics like smaller in size, ability to perform photosynthesis and the ease of culture maintenance. The genome of this cyanobacterium encodes for about 3022 proteins. Out of these 3022 proteins, few proteins were annotated as hypothetical proteins. We performed a computational study to characterize one of the hypothetical proteins “P9303_05031” to deduce its functional role in the cell using various bioinformatics techniques. After in-depth analysis, this hypothetical protein showed the conserved domain as of Hsp10 of molecular chaperonins of GroES. In this work, we have predicted the bidirectional best hits for the hypothetical protein P9303_05031 followed by the prediction of protein properties such as primary, secondary and tertiary structures. The existence of the Hsp10 domain indicates its role is essential for the folding of proteins during heat shock. This work represents the first structural and physicochemical study of the hypothetical protein P9303_05031 in Prochlorococcus marinus MIT 9303.
Sources and pathways for non-directive imperatives
Authors: Holvoet Axel 
Published: March 2020

AbstractThis article deals with the mechanisms by which directive imperatives develop into grams with various non-directive meanings. The types discussed include conditional and concessive, historical, mirative and echoic-necessitive imperatives. It is argued that such non-directive functions should not be traced back to putative general meanings of the imperative but arise, in various specific constructions and through various mechanisms, from the properly directive imperative.
Shallow-cloud impact on climate and uncertainty: A simple stochastic model
Authors: Mueller Eli A. , Stechmann Samuel N. 
Published: March 2020

AbstractShallow clouds are a major source of uncertainty in climate predictions. Several different sources of the uncertainty are possible—e.g., from different models of shallow cloud behavior, which could produce differing predictions and ensemble spread within an ensemble of models, or from inherent, natural variability of shallow clouds. Here, the latter (inherent variability) is investigated, using a simple model of radiative statistical equilibrium, with oceanic and atmospheric boundary layer temperatures,ToandTa, and with moistureqand basic cloud processes. Stochastic variability is used to generate a statistical equilibrium with climate variability. The results show that the intrinsic variability of the climate is enhanced due to the presence of shallow clouds. In particular, the on-and-off switching of cloud formation and decay is a source of additional climate variability and uncertainty, beyond the variability of a cloud-free climate. Furthermore, a sharp transition in the mean climate occurs as environmental parameters are changed, and the sharp transition in the mean is also accompanied by a substantial enhancement of climate sensitivity and uncertainty. Two viewpoints of this behavior are described, based on bifurcations and phase transitions/statistical physics. The sharp regime transitions are associated with changes in several parameters, including cloud albedo and longwave absorptivity/carbon dioxide concentration, and the climate state transitions between a partially cloudy state and a state of full cloud cover like closed-cell stratocumulus clouds. Ideas of statistical physics can provide a conceptual perspective to link the climate state transitions, increased climate uncertainty, and other related behavior.

Published: March 2020

AbstractThe aim of this article is to derive new exact solutions of conformable time-fractional Cahn-Allen equation. We have achieved this aim by hyperbolic function and expa function methods with the aid of symbolic computation using Mathematica. This idea seems to be very easy to employ with reliable results. The time fractional Cahn-Allen equation is reduced to respective nonlinear ordinary differential equation of fractional order. Also, we have depicted graphically the constructed solutions.
Klimaschutz auf Kosten der Armen? Vorschläge für eine markt- und sozialverträgliche Umsetzung von CO2-Steuern und des Emissionshandels
Authors: Wolf Stephan , Goldschmidt Nils 
Published: March 2020

Zusammenfassung
Mit diesem Beitrag schlagen wir einen zweistufigen Weg zu einer effektiven deutschen Klimapolitik vor. Die erste Stufe orientiert sich an der Schweizer CO2-Abgabe: Ab 2020 soll der Kohlendioxidausstoß im privaten Heizenergie- und Verkehrsbereich besteuert werden, da beide Sektoren nicht im EU-Emissionshandel erfasst werden. Wie im Schweizer Modell fließt das Steueraufkommen durch Transfers und Investitionen an die Bevölkerung zurück. Allerdings soll die direkte Rückerstattung auf die Hälfte der Steuereinnahmen beschränkt und auf das einkommensschwächste Drittel der Haushalte konzentriert werden. Die andere Hälfte soll zur Förderung des ländlichen ÖPNV und zur energetischen Sanierung von Mietshäusern eingesetzt werden. Damit wird Klimaschutz – ein Gebot intergenerationeller Gerechtigkeit – im Sinne einer Sozialen Marktwirtschaft umgesetzt: Der Klimaschutzbeitrag jedes Einzelnen orientiert sich auch an Leistungsfähigkeit und Bedürftigkeit. Ab 2030 sollte der zweite Schritt unseres Ansatzes einsetzen und das Steuermodell sukzessive in einen verbraucherbasierten Emissionshandel überführt werden. Ein funktionierendes Personal Carbon Trading System ist allerding technisch und rechtlich komplexer als eine CO2-Steuer. Die sofortige Umsetzung von Stufe eins schafft das nötige Zeitfenster für die Vorbereitung eines Zertifikatesystems für Heizenergie und Mobilität. Die oft angeführten Nachteile eines solchen Systems – hohe Transaktions- und Administrationskosten – halten wir aufgrund der Fortschritte in der Informationstechnologie bereits heute für händelbar. Dafür hätte ein solches System gegenüber einer Steuer folgende Vorteile: Es ist mit dem EU-ETS kompatibel, Emissionsziele werden sicher erreicht und jeder Verbraucher erkennt direkt, für welche CO2-Emissionen er persönlich verantwortlich ist.
Electronic temperature characteristics of laser-induced Fe plasma in fruits
Authors: Fu Yuan-Xia , Wang Li , Xu Li 
Published: March 2020

AbstractFruit is not only delicious, but it also contains iron, potassium, magnesium, and other microelements necessary for the human body. Banana, pineapple and kiwifruit were selected as samples for testing. A laser with a wavelength of 532 nm was focused on the samples’ surface to generate a plasma. The emission spectrum of the atoms and ions in the plasma were collected by optical receivers, and the optimal condition was confirmed by analyzing the signal-to-noise ratio. The electronic temperature characteristics of the Fe plasma were studied under optimal experimental conditions. The maximum electron temperature of the Fe plasma occurred after a time delay of 300 ns in bananas, after 400 ns in pineapples and after 400 ns in kiwifruit. The electronic temperature of the Fe plasma increased with the time delay before the maximum point was reached. However, the temperature decreased after the maximum point was reached. At the beginning of the decline, the plasma decreased rapidly, but later decreased slowly. The range of the variation of the electron temperature of the Fe plasma in bananas, pineapples, and kiwifruits was 12388.29–19958.3 K, 11994.21–16856.4 K, and 13388.2–19607.32 K, respectively.
Nearest Neighbour Particle-Particle Interaction in Fermionic Quasi One-Dimensional Flat Band Lattices
Authors: Tilleke Simon , Daumann Mirko , Dahm Thomas 
Published: March 2020

Abstract
In this paper, we have studied spinless fermions in four specific quasi one-dimensional systems that are known to host flat bands in the noninteracting limit: the triangle lattice, the stub lattice, the diamond lattice, and the diamond lattice with transverse hopping. The influence of the nearest neighbour interaction on the flat bands was investigated. We used exact diagonalization of finite size lattices employing the Lanczos technique and determine the single particle spectral functions of the interacting system. Our results are compared with mean field calculations. In the cases of the triangle lattice and the stub lattice we found that the flat bands become dispersive in the presence of a finite interaction. For the diamond lattice and the diamond lattice with transverse hopping, we demonstrated that the flat bands are robust under the influence of the interaction in certain parameter ranges. Such systems could be realised experimentally with cold atoms in optical lattices.
Die „Sache mit dem Geschlecht“: Zum Stand der Debatte
Authors: Wieser Renate 
Published: March 2020

Zusammenfassung
In öffentlich-medialen Debatten wie im privat-intimen Rahmen werden Fragen rund um das Geschlecht kontrovers und oft auch stark simplifizierend diskutiert. Religionspädagogische Forschung und Praxis braucht, um in diesem Feld fundiert-konstruktiv agieren zu können, den analytischen und differenzierten Blick auf Geschlecht, den die Geschlechterforschung zur Verfügung stellt. Daher bietet der vorliegende Beitrag einen systematischen Einblick in wichtige Entwicklungen und Erkenntnisse der Geschlechterforschung. Im Resultat zeigt sich die Komplexität von Geschlecht als sozialer Kategorie, die in gesellschaftsstrukturelle Verhältnisse, symbolische Wertordnungen und subjektive Identitäten eingewoben ist und sich mit anderen Differenzkategorien wechselseitig verschränkt. Auf Basis eines solchen Kenntnisstandes können religionspädagogische Herausforderungen rund um Geschlechterfragen wahrgenommen, benannt, verstanden und reflektiert werden.

Published: March 2020

In this research, the effect of pulse currents on the weld geometry and angular distortion in pulsed GTAW (PGTAW) process in 3 mm thick SS-304 autogenous butt weld joint was investigated. Welding method uses pulse current and continuous current. The mean current and welding speed were kept constant with the peak current and base current were varied. During pulsed GTAW process, the arc condition was captured directly using a charge-coupled device (CCD) camera. Weld geometry was carried out using a digital microscope. Distortion was measured using Coordinate Measuring Machine (CMM). The results show that the peak current and base current have an influence on weld geometry and angular distortion. The weld geometry on pulsed GTAW was produced wider of weld bead width than continuous GTAW. However, angular distortion on continuous GTAW was higher than pulsed GTAW. Pulsed GTAW can widen the weld bead by 0.57% - 25.09%, but can reduce distortion by 15.15%-88.17%. As compared with weld geometry to the continuous GTAW, the widest result occurs at peak current 212A and base current 40A. The smallest of distortion on pulsed GTAW was achieved at peak current 138A and base current 80A.
MoBPS - Modular Breeding Program Simulator
Authors: Pook Torsten , Schlather Martin , Simianer Henner 
Published: March 2020

AbstractThe R-package MoBPS provides a computationally efficient and flexible framework to simulate complex breeding programs and compare their economic and genetic impact. Simulations are performed on the base of individuals. MoBPS utilizes a highly efficient implementation with bit-wise data storage and matrix multiplications from the associated R-package miraculix allowing to handle large scale populations. Individual haplotypes are not stored but instead automatically derived based on points of recombination and mutations. The modular structure of MoBPS allows to combine rather coarse simulations, as needed to generate founder populations, with a very detailed modeling of todays’ complex breeding programs, making use of all available biotechnologies. MoBPS provides pre-implemented functions for common breeding practices such as optimum genetic contributions and single-step GBLUP but also allows the user to replace certain steps with personalized and/or self-written solutions.

Authors: Rodríguez Hernández Mynor 
Published: March 2020

El acelerado crecimiento de la población adulta mayor, debe ser considerado prioridad por las organizaciones responsables de este sector social. Envejecer es un proceso natural, el cual las personas deben afrontar, así como aceptar los cambios fisiológicos, mentales y sociales que trae. Estos cambios suelen afectar la salud de estas personas y con ello, su calidad de vida. Por lo tanto, este estudio se enfoca en determinar la relación que existe entre el bienestar social, la salud y la calidad de vida de la persona adulta mayor que participa en programas institucionalizados en Costa Rica. Un total de 138 participantes, mujeres y hombres, con edades entre 60 y 86 años (=67,94 años±5,26), de grupos organizados de San Ramón, Costa Rica. La información se recopiló a través del cuestionario SF-36, con el objetivo de conocer la calidad de vida, salud y bienestar social de los adultos entrevistados, las respuestas se analizaron siguiendo la Escala de Ansiedad y Depresión de Goldberg. El análisis de los resultados muestra que la salud, el bienestar social y la calidad de vida son aceptables en este grupo. Existe correspondencia entre la Integración Social y las dimensiones de Salud General, Vitalidad, Función Social y Salud Mental (p<0.01), con la Función Física (p<0.05). La dimensión Contribución Social se relacionó con los dominios de Función Física, Salud General, Vitalidad, Función Social, Salud Mental (p<0.01) y con Transición de Salud (p<0.05). Por su parte la Actualización Social se correlacionó positivamente con la Función Física, Salud Mental y Transición de Salud (p<0.01) y con la Salud General, Vitalidad y Función Social (p<0.05), la salud percibida parcialmente fue más baja en edades avanzadas. El bienestar social es un determinante de la calidad de vida y la salud de las personas adultas mayores, por lo que, implementar estrategias de intervención que incluyan técnicas de socialización podría generar mejoras sustanciales en la salud y la calidad de vida de este grupo poblacional.
Geodetic Model of the 2018 Mw 7.2 Pinotepa, Mexico, Earthquake Inferred from InSAR and GPS Data

Published: March 2020

ABSTRACTInvestigating the interaction between slow-slip events (SSEs) and large earthquakes provides insights into earthquake-triggering mechanisms and is crucial for earthquake hazard assessment. In this study, we used Sentinel-1 Interferometric Synthetic Aperture Radar and Global Positioning System (GPS) data to estimate the source parameters of the 2018 Mw 7.2 Pinotepa, Mexico, earthquake. The results show that the earthquake ruptured both the seismogenic zone and a long-term SSE area, with two asperities ruptured during the event. GPS time-series data indicate that an SSE was initiated approximately during March 2017 below Oaxaca; the SSE ruptured an area below the source region of the Pinotepa earthquake and intruded into the seismogenic zone. The spatiotemporal proximity may suggest that the SSE triggered the Pinotepa earthquake. We propose that the triggering mechanism may either have been Coulomb stress loading or weakening of the source area by fluid migration. Furthermore, we calculated the seismic moment deficit and Coulomb failure stress changes and conclude that the Oaxaca area still has the potential for large earthquakes.
Study of urinary uric acid and creatinine ratio as a marker for perinatal asphyxia
Authors: Gubbala Trinadh , G. N. Shree Krishna 
Published: March 2020

Background: Perinatal asphyxia refers to an impairment of the normal oxygenation during parturition and the ensuing adverse effects on the fetus/neonate. In India, due to birth asphyxia, between 250,000 to 350,000 infants die each year, mostly within the first three days of life. Low APGAR score is commonly used to as a indicator of asphyxia in infants, but it may often be not available and may be reduced in premature infants. In present study we evaluated urinary uric acid and creatinine ratio as a marker for perinatal asphyxia, at our tertiary care hospital.Methods: Present study was a observational, case-control study, conducted in department of paediatrics, in case group consisted of 40 full-term neonates who were hospitalized with the diagnosis of perinatal asphyxia. The control group consisted of 40 healthy full-term newborns.Results: Male to female ratio was 1.5:1 in case group as compared to 1.22:1 in control group. Mean gestational age in case group was 286±10.32 days, while in control group it was 274±7.310 days. Mean birth weight was 2.72±0.51 kg & 2.88±0.49 kg in case & control group respectively. In 52.5 % neonates from case group, signs of intrapartum fetal distress were noted. A statistically significant difference (p<0.005) was noted in Apgar 5 min, Arterial blood pH, pO2 (mm Hg), pCO2 (mm Hg), Urinary uric acid (mg/dl) and Urinary uric acid/ creatinine ratio. Authors did not noted any significant difference in Urinary creatinine (mg/dl) values of cases and control group. Urinary UA/CR ratio is significantly higher in case group when compared with control group with t=11.19; P<0.001.Conclusions: The ratio of urinary uric acid to creatinine helps in rapidly recognizing asphyxia and assessing its severity, so it can be a good, simple screening test for early assessment of neonatal asphyxia.
