Published: August 2020

AbstractSF6 gas is a kind of gas medium widely used in the insulation of power equipment. However, due to the greenhouse effect of SF6, new environmentally friendly gas that can instead of SF6 has been the goal for researchers. CF3I gas is one of the most promising alternative gases for SF6. In this paper, two-term Boltzmann equations of CF3I/N2/CO2 ternary gas mixture at 0.1 MPa and 300 K are calculated to obtain an electron energy distribution function (EEDF), an electron drift velocity Ve, a critical fold breakdown field strength (E/N)cr of the ternary mixed gas, and the synergy effect coefficient is used to analyze the synergy effect between the mixed gases. The calculation results show that the CF3I/N2/CO2 ternary mixture has a synergistic effect, and the 50% CF3I/40% N2/10% CO2 ratio scheme makes the mixed gas most likely to replace SF6 from the physicochemical properties. Comparing the calculated data of this paper with the data of other works of literature, the validity of the calculation method and calculation data in this paper is verified, which provides theoretical support for the research of SF6 alternative gas.

Abstract
This manuscript is concerned with the approximate controllability problem of Hilfer fractional stochastic differential system (HFSDS) with Rosenblatt process and Poisson jumps. We derive the main results in stochastic settings by employing analytic resolvent operators, fractional calculus and fixed point theory. Further, we express the theoretical result with an example.
Comparative crosstalk performance analysis of different configurations of heterogeneous multicore fiber
Authors: Farooque Umar , Ranjan Rakesh 
Published: August 2020

Abstract
In order to select the heterogeneous multicore fiber (MCF) configuration with ultra-low crosstalk and low peak bending radius, comparative crosstalk analysis have been done for the three possible core configurations, namely, Configuration 1 - different refractive index (R.I.) and different radius, Configuration 2 - different R.I., and Configuration 3 - different radius. Using the coupled mode equation and the simplified expressions of mode coupling coefficient (MCC) for different configurations of heterogeneous cores, the crosstalk performance of all the heterogeneous MCF configurations along with the homogeneous MCF have been investigated analytically with respect to core pitch (D) and fiber bending radius (

R

${R}_{b}$

). Further, these expressions of MCC have been extended to obtain the simplified expressions of MCC for the estimation of crosstalk levels in respective trench-assisted (TA) heterogeneous MCF configurations. It is observed from the analysis that in Configuration 1, crosstalk level is lowest and the rate of decrease in the crosstalk with respect to the core pitch is highest compared to the other configurations of heterogeneous MCF. The values of crosstalk obtained analytically have been validated by comparing it with the values obtained from finite element method (FEM) based numerical simulation results. Further, we have investigated the impact of a fixed percent change (5%) in the core parameters (radius and/or R.I.) of one of the core of a homogeneous MCF, to realize the different heterogeneous MCF configurations, on the variations in crosstalk levels, difference in the mode effective refractive index of the core 1 and core 2 (

Therefore, Configuration 1 is the potential choice for the design of MCF with smaller peak bending radius and ultra-low crosstalk level compared to the other configurations of SI-heterogeneous MCF.

Published: August 2020

AbstractGestational diabetes mellitus (GDM) has become a major public health issue and one of the most discussed topics in contemporary obstetrics. Due to rising prevalence of GDM worldwide impact and importance of this medical condition in good quality antenatal care is growing. GDM is associated with serious adverse perinatal outcomes and unfavorable long-term health consequences for both, mother and her child. Despite a great amount of knowledge accumulated regarding GDM, medical community remains indecisive and still debates the most appropriate diagnostic strategy, screening policy, and treatment options for pregnancies complicated with GDM. These unresolved issues generate controversies, motivate further research and contribute to the growing interest surrounding GDM. In this review we will discuss and try to explain some of them.
Couple stress fluid flow due to slow steady oscillations of a permeable sphere
Authors: Aparna P. , Padmaja P. , Pothanna N. , Ramana Murthy J.V. 
Published: August 2020

AbstractThe study of oscillating flow of a Couple Stress fluid past a permeable sphere is considered. Analytical solution for the flow field in terms of stream function is obtained using modified Bessel functions. The formula for Drag acting on the sphere due external flow is evaluated. Pressure field for the flow region past and inside the sphere is obtained. Effects of physical parameters like couple stress parameter, permeability, frequency and geometric parameters on the drag due to internal and external flows are represented graphically. It is observed that the drag for viscous fluid flow will be less than the case of couple-stress fluid flow and hence couple stress fluids offer resistance for flow.
Adsorptive removal of PAR and Arsenazo-III from radioactive waste solutions by modified sugarcane bagasse as eco-friendly sorbent

Published: August 2020

Abstract
In this paper, sugarcane bagasse (SCB) was modified using phosphoric acid. The modified sugarcane bagasse (MSCB) has been used to remove 4-(2-pyridylazo)resorcinol (PAR) and Arsenazo-III (Ar-III) from liquid radioactive waste. The surface morphology and functional groups of the MSCB were studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). Adsorption ability of MSCB has been tested by batch mode through some relevant factors like initial pH, reaction time, initial coloring reagents (PAR and Ar-III) concentrations, and adsorbent weight. At adsorption equilibrium time 180 min and pH values of 3 and 1 for PAR and Ar-III; the maximum removal (%) for both PAR and Ar-III were 93 and 57%, respectively. The adsorption isotherm data are representative well to Freundlich isotherm model. The mean free energy of adsorption, E (kJ/mol), has been estimated as 5.75 and 2.28 kJ/mol for PAR and Ar-III, respectively, which suggests that the adsorption occurred physically. The maximum adsorption capacity of MSCB for PAR and Ar-III is 96.62 and 15.18 mg/g, respectively. The adsorption kinetics are better fitted by the pseudo-second-order model. The partial film along with intra-particle diffusion controlled the diffusion of coloring reagents from the solution bulk to the particle interior pores. Application of MSCB for removing PAR and Ar-III from simulated liquid radioactive waste containing U(VI) and Th(VI) ions has been achieved successfully.
Italian Auction Market: Features of Discounted Forced Sale Price

Published: August 2020

AbstractThe purpose of the paper is to investigate the main causes of discount between list price and forced sale value in the Italian real estate auction segment, in favor of more comprehensive determination of the value of mortgage underlying guarantees; this would allow for an improvement of further valorization processes of assets intended to obtain a higher selling price.Starting from the results of existing literature, an ordinary least squares regression analysis was conducted in order to point out the main determinants of the discount between list price and forced sale value. It has been verified, when sampling 225 cases of forced residential property sales in the South of Italy, that the time constraint of the Italian regulatory framework is more relevant with reference to discount rather than the physical characteristics of assets.The influence of the duration of procedures is proof that even if recent government initiatives have led to positive results in terms of reducing the length of procedures, this is not yet satisfactory compared to other European contexts. This provides evidence of the need for further interventions aimed at improving the efficiency of the procedural system, also encouraging recourse to other options that lead to ease judicial burden.
Property Price Modelling, Market Segmentation and Submarket Classifications: A Review
Authors: Usman Hamza , Lizam Mohd , Adekunle Muhammad Usman 
Published: August 2020

AbstractAccurate pricing of the property market is necessary to ensure effective and efficient decision making. Property price is typically modelled using the hedonic price model (HPM). This approach was found to exhibit aggregation bias due to its assumption that the coefficient estimate is constant and fails to consider variation in location. The aggregation bias is minimized by segmenting the property market into submarkets that are distinctly homogeneous within their submarket and heterogeneous across other submarkets. Although such segmentation was found to improve the prediction accuracy of HPM, there appear to be conflicting findings regarding what constitutes a submarket and how the submarkets are to be driven. This paper therefore reviews relevant literature on the subject matter. It was found that, initially, submarkets were delineated based on a priori classification of the property market into predefined boundaries. The method was challenged to be arbitrary and an empirically statistical data-driven property submarket classification was advocated. Based on the review, there is no consensus on the superiority of either of the methods over the another; a combination of the two methods can serve as a means of validating the effectiveness of property segmentation procedures for more accurate property price prediction.

Abstract
Social wasps of the genus Vespula have spread to nearly all landmasses worldwide and have become significant pests in their introduced ranges, affecting economies and biodiversity. Comprehensive genome assemblies and annotations for these species are required to develop the next generation of control strategies and monitor existing chemical control. We sequenced and annotated the genomes of the common wasp (Vespula vulgaris), German wasp (Vespula germanica), and the western yellowjacket (Vespula pensylvanica). Our chromosome-level Vespula assemblies each contain 176–179 Mb of total sequence assembled into 25 scaffolds, with 10–200 unanchored scaffolds, and 16,566–18,948 genes. We annotated gene sets relevant to the applied management of invasive wasp populations, including genes associated with spermatogenesis and development, pesticide resistance, olfactory receptors, immunity and venom. These genomes provide evidence for active DNA methylation in Vespidae and tandem duplications of venom genes. Our genomic resources will contribute to the development of next-generation control strategies, and monitoring potential resistance to chemical control.

Published: August 2020

ABSTRACTThe aim of this study was to further develop and extensively describe a surgical technique in order to realise long-term fetal blood sampling in the bovine species. Eleven Holstein–Friesian 6- to 8-month pregnant cows (4–10 years old) were used for this study. Gestational age on the day of surgery varied from approximately 180 days (n = 1) to 240 days (minimum: 232 days, maximum 252 days; n = 10). The fetal medial tarsal artery was catheterised in pregnant cows with a polyvinyl catheter in dorsal recumbency under general anaesthesia. Although 5 out of 11 operations (45.5%) performed between 232 and 252 days of gestation were lost due to different causes mainly associated with peritonitis and septicaemia, the mean interval between operations and calvings was 42.5 days (between 27 and 95 days). It is important to emphasise that a well-trained surgical team is needed for bovine fetal cannulation in order to be able to decrease the risk factors during the operations. Due to the fact that after 5 unsuccessful cases none of the pregnancies were lost, this skill can be reached, and our technique can enable bovine fetal blood sampling for long-term endocrinological and physiological investigations before and during parturition.

Elméleti háttérA féltékenység mérésének számos egydimenziós és komplex mérőeszközét különböztethetjük meg egymástól. A mérőeszközök egyike a diszpozícionális féltékenységet mérő 25 tételes Önbevallásos Féltékenység Skála.CélAz Önbevallásos Féltékenység Skála magyar nyelven nem érhető el, ezért a jelen tanulmány elsődleges célja e hiány pótlása, a kérdőív nagy elemszámú és széles életkori spektrumot átfogó mintán történő hazai adaptációja során szerzett tapasztalatok közreadása.MódszerA keresztmetszeti, kérdőíves vizsgálaton alapuló kutatás során 1384 egészséges vizsgálati személy (átlagéletkor 27,3 [SD = 9,10] év) adatainak felhasználásával tártuk fel az Önbevallásos Féltékenység Skála faktorstruktúráját, annak illeszkedését, illetve teszteltük a mérési hatékonyság belső stabilitását.EszközökA tesztbattéria az Önbevallásos Féltékenység Skála mellett a validitás vizsgálatát szolgáló kérdőíveket az Epidemiológiai Kutatási Központ - Depresszió Skáláját, a Spielberger-féle Vonásszorongás Kérdőívet, a Pszichológiai Jóllét Skálák kérdőívet, a WHO Jóllét Kérdőívének rövidített változatát, a Kapcsolati Elégedettség Skálát, valamint a Rosenberg Önértékelés Skálát tartalmazta.EredményekA feltáró faktoranalízis a kérdőív négy dimenzióját azonosította (a Párkapcsolati gyanakvás, a Reális párkapcsolati féltékenység, a Társas féltékenység és a Testvérféltékenység), amelyek a teljes variancia 62%-át magyarázzák. A konfirmátoros faktoranalízis az eredeti, háromfakto- ros modellel szemben a négydimenziós modell esetén jelzett megfelelő illeszkedést. A reliabilitásvizsgálat magas belső konzisztenciát mutatott. A nemi különbség, a részletes életkori csoportok elemzése és a párkapcsolati státusz vonatkozásában kapott adatok igazolják a féltékenység konstruktumvaliditását. Továbbá, a korábbi empirikus kutatásoknak megfelelően a féltékenység és az önértékelés vonatkozásában kapott gyenge negatív együttjárás (r = –0,28; p < 0,001) és a féltékenység depresszióval kapcsolatos gyenge pozitív (r = 0,30; p < 0,001) és szorongással kapcsolatos mérsékelt pozitív korrelációja (r = 0,37; p < 0,001) alátámasztja az Önbevallásos Féltékenység Skála konstruktum validitását. A Párkapcsolati gyanakvás és a Reális párkapcsolati féltékenység korrelációs együtthatói értékes információval járulnak hozzá a féltékenység megítélésének adaptív vs. maladaptív voltához.ÖsszefoglalásAz eredmények tükrében az Önbevallásos Féltékenység Skála a diszpozícionális féltékenység mértékének megbízható és érvényes mérőmódszere, amely további populációszintű és klinikai mintán történő kutatás számára nyújthat adekvát mérőeszközt.

Published: August 2020

Scope of the study was to find more effective N fertilisation doses and applications to reach not only higher quantity but better quality grains as well as to be able to help preserving the continuity of feed and food quality improvement, since wheat is one of the most consumed crops all over the world.Samples of winter wheat (Triticum aestivum L.) varieties harvested from the experimental field of the Szent István University in two consecutive crop seasons had been examined in the laboratory of the Crop Production Institute. Effects of nitrogen (N) application on the performance of grain protein were tested. Five high quality winter wheat varieties were studied regarding grain quality traits affected by applying undivided and split doses of N. The evaluated samples show that increasing doses of N topdressing and increasing time of application have beneficial effects on the yield and the value of protein content. Wheat grain protein value ranged between 9.9% of the untreated Mv Karéj and Alföld, where the 120+40 kg ha-1 N was applied resulting in the highest value of 16.0%. Similarly, the gluten values among untreated and N applied plots were in a wide range. Mv Karéj had the lowest wheat gluten value on untreated plot with 18.4% and Alfold had the highest value with 36.8% on the plot where the 120+40 kg ha-1 N was applied. There were no significant changes recorded on test weight and thousand kernel weight. In the case of baking quality, there were significant differences between varieties. The best records were obtained in the case of Mv Toborzö followed by Mv Karéj.
Sharing-Based Co-Housing Categorization. A Structural Overview of the Terms and Characteristics Used in Urban Co-Housing

Published: August 2020

The European urban areas are growing fast, with many contemporary housing forms. Among these, co-housing forms related to sharing have become a key issue for urban housing development. These housing forms are analysed (their physical and social characteristics or effects) in more and more publications, without a common terminology of this interdisciplinary research field. In our study, based on the overview of existing definitions, characteristics we introduce a comprehensive sharing based categorization that could be valuable for terms and projects, as well. With the note, that the social dimension of sharing methods would not exist without the physical ones, because in co-housing the shared space is the basic criteria. In this paper, we focus on three groups of the social fields of sharing related to housing: the shared creation, the shared tenure, and the shared activities. We conclude the structural approach of our overview unravels new perspectives for the classification of housing forms. Based on our categorization and methodology, we recommend the development of a sharing based scalable classification that measures projects consistent and comparable.Összefoglaló. A városias, beépített területek aránya Európa szerte folyamatosan növekszik, ennek következtében kortárs városi lakhatási formák is teret nyernek. A megosztáshoz kötődő, úgynevezett co-housing formák a kortárs városi lakófejlesztések jelentős részét képzik. Éppen ezért egyre több elemzés és publikáció születik a témában (például a fizikai és társadalmi jellemzőikről vagy azok hatásairól), azonban a lakhatás kutatási területén nincs egyetértés a kifejezések és definíciók használatában. A következő tanulmányban egy, a lakhatási formákat megosztás alapján rendszerező kategorizáció kerül bemutatásra, melynek elméleti és gyakorlati haszna is lehet. A kategorizáció a meglévő kifejezésekre, definíciókra és jellemzőkre egyaránt épít. A co-housing lakhatás alapvető feltétele a – változó méretű és minőségű – megosztott tér, így a társadalmi dimenziók minden esetben kötődnek egy fajta tériséghez is. A lakhatási formákban jelenlévő társadalmi és fizikai dimenziók együttes vizsgálata nem képezi jelen kutatás tárgyát, a társadalmi típusúakra koncentrál: a megosztott létrehozásra, tulajdonlásra és a tevékenységekre. Megállapítható, hogy a kutatás során alkalmazott rendszerezett áttekintés új irányvonalakra mutatott rá a lakhatási formák osztályozásának területén. A tanulmányban tárgyalt megosztás-alapú kategorizálásra és módszertanra alapozva egy, a megosztásra épülő és skálázható osztályozás kidolgozása javasolt, melyben a projektek mérése és összehasonlítása egységes módon történhet.
