Abstract. Murni D, Lestari U, Indriwati SE, Efendi A, Maryani N, Amin M. 2020. Morphometric diversity and phenotypic relationship among indigenous buffaloes of Banten, Indonesia. Biodiversitas 21: 933-940. This study aimed to describe the morphometric diversity and phenotypic relationship among indigenous buffaloes of Banten, Indonesia. In this study, 125 buffaloes from six regions were investigated based on 11 morphometric characters. Morphometric diversity was analyzed using multivariate discriminant analysis. The Euclidean genetic distances were used to estimate the phenotypic relationship among the buffalo populations. The indigenous buffaloes of Banten have high morphometric diversity, with a coefficient from 2.83 to 41.43%. The body length and chest circumference can be used as a morphometric marker to determine potential indigenous buffaloes as their high correlation coefficient value (0.506). The Serang district buffaloes have the highest mean of body length and chest circumference, which shows that this population is potential compared to the populations from other regions. The morphometric of buffalo population from Serang City, Cilegon City, Serang District, and Pandeglang District tend to be homogenous. Meanwhile, Lebak and Tangerang District population tends to heterogeneous. According to Euclidean distance analysis, the proximate phenotypic relationship was between Serang and Pandeglang District's buffalo populations. Our results indicated that morphometric diversity and phenotypic relationships of the populations were related to geographical origins and can be used to determine the potential indigenous of buffaloes.

Abstract. Garvita RV, Wawangningrum H. 2020. Stomata cells studies of Paraphalaenopsis spp. from in vitro and greenhouse condition. Biodiversitas 21: 1116-1121. In vitro micropropagation is an efficient biotechnological strategy for conservation and commercial plantlet production. The ultimate success of in vitro microporapagation depends on the ability to transfer plants out of culture, known as acclimatization stage. The morphology, anatomy and physiology of plantlets in in vitro culture conditions is different from the plants in environment condition (greenhouse), therefore they are unable to compete with soil microbes and to cope with the environmental conditions. The aim of this research is to determine stomata morphology and distribution of Paraphalaenopsis spp (Orchidaceae) from in vitro growth and greenhouse conditions. The leaf stomata cells of Paraphalaenopsis spp. (Paraphalaenopsis serpentilingua, Paraphalaenopsis labukensis and Paraphalaenopsis laycockii) was undertaken by observing the stomata preparation of the upper leaf and lower leaf by using microscope fitted with optic visual seven. The descriptive method was used to describe the stomata morphology by observing the epidermis of longitudinal section and stomata length of upper and lower leaf by using a microscope. The results showed that these plants had anomocytic type of stomata cells. The distributions of stomata are in the upper and lower epidermis leaf in all Paraphalaenopsis spp from in vitro growth and greenhouse.

Abstract. Fagundes M, Santos EML, Duarte KLR, Santos LM, Vieira JS, Oliveira CHD, Silva PS. 2020. Diversity of gall-inducing insect associated with a superhost plant species: Plant architecture, resource availability and interspecific interactions. Biodiversitas 21: 1182-1189. The role of interspecific competition in the organization of herbivorous insect communities may vary depending on resource availability. Trees are structurally more complex and have greater resource availability for herbivorous insects than shrubs. In this study, we evaluated the roles of plant architecture and interspecific interactions on community organization of the gall-inducing insect associated with trees (adult plants) and shrubs (young plants) of Copaifera langsdorffii. Our results showed that the species composition of gall-inducing insect communities associated with C. langsdorffii differed statistically between trees and shrubs. In addition, the trees presented greater diversity of gall-inducing insects than the shrubs, corroborating the hypothesis of plant architecture. The results of the analysis of null models showed that the co-occurrence of gall-inducing insect species associated with trees not differ from the co-occurrence predicted by chance. Thus, interspecific interactions cannot be used to explain the community organization of the gall-inducing insects on C. langsdorffii trees. On the other hand, the co-occurrence of gall-inducing insect species differed from the co-occurrence predicted by chance when shrubs plants were analyzed, indicating that biotic interactions can shape the structure of the gall-inducing insect community on shrubs. The lower availability of oviposition sites probably generates a dispute for these resources among females of different species of gall-inducing insects only in the shrubs. Therefore, the role of competition in the organization of herbivore insect communities on their host plant may vary depending on the ontogenetic stage of the host plant.
Inverse design of photonic structures using an artificial bee colony algorithm
Authors: Malheiros-Silveira Gilliard N. , Delalibera Fabianno G.
Published: March 2020

We adapted the standard artificial bee colony algorithm for a binary search space in order to optimize photonic structures. The artificial bee colony algorithm in conjunction with the finite element method is applied for maximizing photonic bandgaps of photonic crystals. The proposed approach is assessed by two case studies assuming 2D photonic crystals comprised of silicon and air in a triangular lattice. The crystals were optimized to present large photonic bandgaps. The artificial bee colony algorithm presented superior performance when compared with that of a standard genetic algorithm, demonstrating an interesting approach to be used on the inverse design or optimization of photonic structures.
Vector wave simulation of active imaging through random media
Authors: Shen Zhean , Dogariu Aristide
Published: March 2020

When a target is embedded in random media, the quality of optical
imaging can be improved by actively controlling the illumination and
exploiting vector wave properties. A rigorous description, however,
requires expensive computational resources to fully account for the
electromagnetic boundary conditions. Here, we introduce a
statistically equivalent scaling model that allows for reducing the
complexity of the problem. The new scheme describes the entanglement
between the local wave vector and the polarization state in random
media and also accounts for cumulative properties such as geometric
phase. The approach is validated for different scenarios where the
coherent background noise alters substantially the performance of
active imaging.
Feature matching based on curve descriptor and local D-Nets for fish-eye images
Authors: Zhang Yakun , Zhang Hongsheng , Zhang Wenming
Published: March 2020

Most feature-matching algorithms based on perspective images, such as scale-invariant feature transform (SIFT), speeded up robust features, or DAISY, construct their feature descriptors from the neighborhood information of feature points. Large nonlinear distortion results in different amounts of neighborhood information at different feature points within the fish-eye images, especially for the case when a feature pixel is at the central region and the corresponding feature pixel is at the periphery. In contrast, descriptor-Nets (D-Nets) is a feature-matching algorithm based on global information. It is more robust, but it is time-consuming. In this paper, we employ the SIFT detector to extract feature pixels, and then we propose a novel feature-matching strategy based on the D-Nets algorithm. We modify the linear descriptors in the traditional D-Nets algorithm and propose a curve descriptor based on the hemispheric model of a fish-eye image. In the traditional D-Nets algorithm, each feature point is described by all other pixels of the entire image, and complicated calculations cause slow matching speed. To solve this problem, we convert the traditional global D-Nets into a novel local D-Nets. In the experiment, we obtain image pairs from real scenery using the binocular fish-eye camera platform. Experimental results show that the proposed local D-Nets method can achieve more than 3 times the initial matching pixels, and the percentage of bad matching is reduced by 40% compared with the best performing method among the comparison methods. In addition, the matching pixel pairs obtained by the proposed method are evenly distributed, either in the center region with small distortion or in the peripheral region with large distortion. Meanwhile, the local D-Nets algorithm is 16 times less than that of the global D-Nets algorithm.
Time-domain analysis on the pulsed squeezed vacuum detected with picosecond pulses
Authors: Taguchi Yoshitaka , Ozeki Yasuyuki
Published: March 2020

The pulsed squeezed state of
light is expected to enhance the sensitivity of optical measurements
using optical pulses. To achieve a high squeezing level, it is crucial
to explore its limiting factors. In this study, we analyze the pulsed
squeezed vacuum detected with picosecond pulses to explore two
critical factors that limit the achievable squeezing level. First, we
investigate the effect of the frequency chirp of local oscillator (LO)
pulses and show that there exists an upper bound of the chirp
parameter for a given squeezing level. Next, we analyze the effect of
temporal matching between the LO pulse and the squeezed vacuum and
point out the importance of temporal broadening in nonlinear optical
crystals for squeezing.

Published: March 2020

Objective: The aim of this study was to evaluate the influence of different crowns finishing line location on the crown tensile bond strength, marginal adaption and nanoleakage. Material and Methods: Sixty healthy third molars were collected. For tensile bond strength, a self-adhesive resin cement was used. For marginal adaption, epoxy resin models were prepared. Prior to tensile bond strength test, images for the epoxy resin models were measured under scanning electron microscopy (SEM). Nanoleakage was measured using same protocol. Failure mode was evaluated through SEM and classified: adhesive failure, cohesive in cement, cohesive in dentin, cohesive in resin composite, cohesive in enamel, and mixed. Statistical analysis was performed using Shapiro-Wilk and Kolmogorov Smirnov normality tests, two-way ANOVA, Bonferroni (posthoc) parametric test, with significance level of 5% (P < .05), Spearman correlation test. Results: tensile bond strength was not statistically different between the cemented groups with composite resin and ceramic. Cementation of ceramic was not statistically different between the groups (enamel, 3.28 Pa; dentin, 3.14 Pa; resin, 2.85 Pa). Marginal adaption was statistically different between resin and ceramic; finish line location varied between enamel and resin (175.91 ?m vs. 433.58 ?m). Nanoleakage rate was statistically different among all groups, except for resin: with resin (9.49%) and ceramic (9.35%). There was a predominance of adhesive failure in all groups. Conclusion: finish line location can be performed safely in enamel and dentin. Composite resinas substrate present an alternative, but still need to be more studied. Regarding the crown’s material, it is possible to perform a satisfatory restoration in both: resin and ceramic. With ceramics presenting better results. KEYWORDSResin composite; Ceramics; Tensile bond strengh; Marginal adaption; Nanoleakage.

INVESTIGATION OF THE POSSIBILITIES OF ULTRASONIC TESTING OF CAST IRON WITH LAMELLAR GRAPHITE USING STANDARD NORMAL PROBE
Authors: Danilov V. N. , Voronkova L. V.
Published: March 2020

Computer simulation of acoustic paths for medium – cast iron with lamellar graphite for standard normal probe of several types was carried out in order to study the effect of such medium on the characteristics of transmitted and received signals during ultrasonic testing. In the course of studies to calculate the attenuation coefficient of longitudinal waves in cast iron with lamellar graphite, due to their Rayleigh and phase scattering by graphite inclusions, the previously developed model was used. Comparison of the results of calculations of spectra and pulses of the recorded signals for two samples of cast iron with lamellar graphite confirmed the possibility of using the developed calculation model for a description of real physical phenomena adequate for the practice of ultrasonic testing. The ratio of the recorded signal and structural noise levels for different models of transducers, reflectors and characteristics of the controlled cast iron is estimated. Shown that increased attenuation of the longitudinal wave in cast iron in comparison with steel as a result of scattering by inclusions leads to higher level of this noise and can greatly reduce the signal-to-noise ratio in the detection of the reflected from the defect signals.

Natural justice theory: what it means for the right to privacy and LGBT rights in India
Authors: Badkur Vivek
Published: March 2020

This paper analyzes two landmark judgments on the right to privacy and LGBTQ+ rights in India. Both of these judgments form part of the same picture, the article analyses these judgments and their decision-making approach in light of natural justice theory. The Supreme Court’s recognition of the right to privacy paves way for the protection of LGBT rights in India. The cumulative effect of the two judgments under analysis demonstrate the need for an expansive interpretation of fundamental and natural rights using natural justice theory.
Análisis de las medidas de protección a los defensores de derechos humanos en Colombia, 2016-2019.

Published: March 2020

Es indudable que el trabajo de los defensores de derechos humanos en Colombia ha sido piedra angular para promover la protección a los derechos humanos y convencionales de las comunidades que, por una u otra razón, se han visto vulneradas; por este motivo, es fundamental que el Estado tenga la capacidad para proteger su actividad y garantizar que cualquier persona que pretenda atacar a quienes promueven los derechos humanos sea inmediatamente reducido y, de igual forma, el defensor sea cobijado por el manto institucional en relación con las garantías constitucionales, internacionales y convencionales.

Se vuelve prioritario puntualizar cuáles son las medidas de protección que cubren a los defensores de derechos humanos en Colombia y evidenciar la realidad que viven en ejercicio de sus actividades.
Geolocators reveal migration routes, stopover sites, and nonbreeding dispersion in a population of Cerulean Warblers
Authors: Delancey Clayton D , Islam Kamal , Kramer Gunnar R , MacDonald Garrett J , Sharp Alexander R , Connare Brandon M
Published: March 2020

Cerulean Warblers (Setophaga cerulea) are among the fastest declining Nearctic-Neotropical migrant wood-warblers (Parulidae) in North America. Despite ongoing conservation efforts, little is known about their non-breeding distribution. In June 2016-2018, we deployed geolocators (n = 30) on adult male Cerulean Warblers in Indiana, USA, to track annual movements of individuals. Recovered geolocators (n = 4) showed that Cerulean Warblers occurred broadly throughout northern South America. Autumn migration lasted 44-71 days (n = 4), whereas spring migration lasted 37-41 days (n = 3). The average migration distance was 5268 km. During autumn migration, Cerulean Warblers made 1-4 stopovers (i.e., ≥2 days; n = 4) and 1-2 stopovers during spring migration (n = 3). When crossing the Gulf of Mexico during autumn migration, two birds stopped over after crossing, but not beforehand. Two others navigated through the Caribbean rather than crossing the Gulf of Mexico. During spring migration, one individual stopped after crossing, one individual stopped before crossing, and one individual stopped before and after crossing the Gulf of Mexico. No birds migrated through the Caribbean Islands during spring migration. These results represent novel information describing annual movements of individual Cerulean Warblers and will inform conservation efforts for this declining species.
On one approach to the approximation of solutions to the direct kinematics problem of parallel manipulators
Authors: Gorchakov Andrei , Mozolenko Vyacheslav
Published: March 2020

Any real continuous bounded function of many variables is representable as a superposition of functions of one variable and addition. Depending on the type of superposition, the requirements for the functions of one variable differ. The article investigated one of the options for the numerical implementation of such a superposition proposed by Sprecher. The superposition was presented as a three-layer Feedforward neural network, while the functions of the first’s layer were considered as a generator of space-filling curves (Peano curves). The resulting neural network was applied to the problems of direct kinematics of parallel manipulators.
Galvanic corrosion of carbon steel under concentration cell formation in MgCl2 solution as an inorganic pollutant and the effect of flow velocity
Authors: Ali Marwa E.M. , Hasan Basim O.
Published: March 2020

The wastewater of petroleum refineries consists of various corrosive pollutants that are harmful not only for human and living organisms but also for the equipment and materials exposed to it. The galvanic corrosion of carbon steel in MgCl2 solution as a pollutant in petroleum refinery wastewater was studied under concentration cell formation. The influence of different operating parameters on the galvanic corrosion established by concentration cell was studied, and the concept of concentration cell corrosion was examined and discussed versus experimental results. The effects of some operating conditions on the galvanic behavior, such as the concentration of MgCl2 (0–2500 ppm) and solution flow velocity (150–1000 rpm), on corrosion rate, corrosion potentials, and corrosion current were investigated. New findings regarding the effect of corrosive substance concentration and the hydrodynamics on the corrosion rate of each electrode and the galvanic current were reported. It was found that the corrosion rate of carbon steel in both cell poles increases with increasing MgCl2 concentration in both free and galvanic corrosion. Increasing MgCl2 concentration also led to an increase in the galvanic currents and the corrosion rate of the two electrodes. The flow velocity in either cell terminal considerably influences the potentials, corrosion rates of both electrodes, and the galvanic current passing in the cell. A high flow velocity in the compartment with the more negative potential caused polarity reversal on some occasions.
Relations between ageing and dependence for exchangeable lifetimes with an extension for the IFRA/DFRA property
Authors: Nappo Giovanna , Spizzichino Fabio
Published: March 2020

We first review an approach that had been developed in the past years to introduce concepts of “bivariate ageing” for exchangeable lifetimes and to analyze mutual relations among stochastic dependence, univariate ageing, and bivariate ageing.

A specific feature of such an approach dwells on the concept of semi-copula and in the extension, from copulas to semi-copulas, of properties of stochastic dependence. In this perspective, we aim to discuss some intricate aspects of conceptual character and to provide the readers with pertinent remarks from a Bayesian Statistics standpoint. In particular we will discuss the role of extensions of dependence properties. “Archimedean” models have an important role in the present framework.

In the second part of the paper, the definitions of Kendall distribution and of Kendall equivalence classes will be extended to semi-copulas and related properties will be analyzed. On such a basis, we will consider the notion of “Pseudo-Archimedean” models and extend to them the analysis of the relations between the ageing notions of IFRA/DFRA-type and the dependence concepts of PKD/NKD.
Exploring the role of adipsin in statin-induced glucose intolerance: a prospective open label study
Authors: Maini Jahnavi , Rehan Harmeet Singh , Yadav Madhur , Gupta Lalit Kumar
Published: March 2020

Background

Evidence from the literature, highlights the increased risk of developing glucose intolerance and type 2 diabetes mellitus (T2DM) with statin therapy. In addition, few animal studies demonstrate that adipsin secreted from adipocytes plays a crucial role in insulin secretion and the development of T2DM.

Methods

To further explore the role of serum adipsin, in this prospective open label study, 55 newly diagnosed dyslipidemic patients were enrolled. Before starting statin therapy, liver function test (LFT), kidney function test (KFT), lipid profile, glycemic parameters [glycated hemoglobin A (HbA1c), fasting blood sugar (FBS), and postprandial blood sugar (PPBS)], serum insulin, and serum adipsin were estimated. Then these patients were prescribed statin (i.e. atorvastatin, rosuvastatin, or pitavastatin) and after 12 weeks of therapy, all the above investigations were repeated.

Results

After 12 weeks of statin therapy, the LFT and KFT values remained unchanged and lipid parameters showed significant improvement. But the glycemic parameters deranged significantly (p < 0.001), i.e. FBS, PPBS, and HbA1c increased by 12.49% (102.99 ± 20.76 mg/dL), 24.72% (147.71 ± 47.29 mg/dL), and 21.43% (6.38 ± 1.34%), respectively. On the other hand, the baseline adipsin (2.73 ± 1.99 ng/mL) and insulin (16.13 ± 12.50 mIU/L) levels reduced significantly (p < 0.0001) to 1.43 ±1.13 ng/mL and 6.91 ± 5.93 mIU/L, respectively. The reduction in serum adipsin also showed a positive correlation with reduction in serum insulin (r = 0.85; p < 0.0001). None of the patients experienced any significant adverse effect or reaction leading to discontinuation of therapy.

Conclusions

There might be an association between reduction in adipsin and development of glucose intolerance by statin therapy.

Authors: Dandabathula Giribabu , Verma Manish , Rao Sitiraju Srinivasa
Published: March 2020

NASA’s new Earth-Observing satellite namely ICESat-2 estimates the elevation of ice sheets, glaciers, sea ice, land surface, and canopy with the help of photon counting ATLAS sensor on-board. Higher-level data products like ATL08 uses an iterative filtering approach of the signal photons for capturing canopy height and terrain height. This article provides results from the evaluation of best-fit elevation on land from ICESat-2 ATL08 data product with DGPS surveyed points. 40 points were surveyed for elevation in the arid region with different topographies of varied surface cover. Mean bias error computed from the best-fit elevation from ICESat-2 ATL08 data product and corresponding DGPS surveyed points is near close to zero for the segments created from strong beams. The conformity between these two sets of elevation values is better than 12 cm (RMSE) if we use the segments from strong beam for the topographic variations ranging from flat to almost flat type.
Identification of Non-Equilibrium Beliefs in Games of Incomplete Information Using Experimental Data
Authors: Aguirregabiria Victor , Xie Erhao
Published: March 2020

This paper studies the identification of players’ preferences and beliefs in discrete choice games using experimental data. The experiment comprises a set of games that differ in their matrices of monetary payoffs. The researcher is interested in the identification of preferences (utility of money) and beliefs on the opponents’ expected behavior, without imposing equilibrium restrictions or parametric assumptions on utility and belief functions. We show that the hypothesis of unbiased/rational beliefs is testable as long as the set of games in the experiment imply variation in monetary payoffs of other players, keeping the own monetary payoff constant. We present conditions for the full identification of utility and belief functions at the individual level – without restrictions on players’ heterogeneity in preferences or beliefs. We apply our method to data from two experiments: a matching pennies game, and a public good game.
Predictive value of thyroxine for prognosis in pediatric septic shock: a prospective observational study
Authors: Song Jia , Cui Yun , Wang Chunxia , Dou Jiaying , Miao Huijie , Xiong Xi , Zhang Yucai
Published: March 2020

Background

Thyroid hormone plays an important role in the adaptation of metabolic function to critically ill. The relationship between thyroid hormone levels and the outcomes of septic shock is still unclear. The aim of this study was to assess the predictive value of thyroid hormone for prognosis in pediatric septic shock.

Methods

We performed a prospective observational study in a pediatric intensive care unit (PICU). Patients with septic shock were enrolled from August 2017 to July 2019. Clinical and laboratory indexes were collected, and thyroid hormone levels were measured on PICU admission.

Results

Ninety-three patients who fulfilled the inclusion criteria were enrolled in this study. The incidence of nonthyroidal illness syndrome (NTIS) was 87.09% (81/93) in patients with septic shock. Multivariatelogisticregression analysis showed that T4 level was independently associated with in-hospital mortality in patients with septic shock (OR: 0.965, 95% CI: 0.937–0.993, p = 0.017). The area under receiver operating characteristic (ROC) curve (AUC) for T4 was 0.762 (95% CI: 0.655–0.869). The cutoff threshold value of 58.71 nmol/L for T4 offered a sensitivity of 61.54% and a specificity of 85.07%, and patients with T4 < 58.71 nmol/L showed high mortality (60.0%). Moreover, T4 levels were negatively associated with the pediatric risk of mortality III scores (PRISM III), lactate (Lac) level in septic shock children.

Conclusions

Nonthyroidal illness syndrome is common in pediatric septic shock. T4 is an independent predictor for in-hospital mortality, and patients with T4 < 58.71 nmol/L on PICU admission could be with a risk of hospital mortality.
The impact of general anesthesia on mother-infant bonding for puerperants who undergo emergency cesarean deliveries
Authors: Nitahara Kenta , Hidaka Nobuhiro , Sakai Atsuhiko , Kido Saki , Kato Kiyoko
Published: March 2020

Background

Mother-infant bonding is an emerging perinatal issue. While emergency cesarean deliveries are associated with a risk of bonding disorders, the mode of anesthesia used for emergency cesarean deliveries has never been studied in this context. We aimed to investigate the impact of administering general anesthesia and neuraxial anesthesia to women undergoing cesarean deliveries on mother-infant bonding.

Methods

This was a retrospective, propensity score-matched multivariable analysis of 457 patients who underwent emergency cesarean deliveries between February 2016 and January 2019 at a single teaching hospital in Japan. The Mother-Infant Bonding Scale (MIBS) scores at hospital discharge and the 1-month postpartum outpatient visit were evaluated in the general anesthesia and the neuraxial anesthesia groups. A high score on the MIBS indicates impaired mother-infant bonding.

Results

The primary outcome was the MIBS score at hospital discharge in propensity score-matched women. After propensity score matching, the median [interquartile range (IQR)] MIBS scores were significantly higher in the general anesthesia group than those in the neuraxial anesthesia group at hospital discharge [2 (1–4) vs. 2 (0–2); P = 0.015] and at the 1-month postpartum outpatient visit [1 (1–3) vs. 1 (0–2); P = 0.046]. In linear regression analysis of matched populations, general anesthesia showed a significant and positive association with the MIBS scores at hospital discharge [beta coefficient 0.867 (95% confidence interval [CI] 0.147–1.59); P = 0.019] but not at the 1-month postpartum outpatient visit [0.455 (−0.134 to 1.044); P = 0.129].

Conclusion

General anesthesia for emergency cesarean delivery is an independent risk factor associated with impaired mother-infant bonding.
Verb phrase secondary predication: Biblical Hebrew as a case study
Authors: Hatav Galia
Published: March 2020

In this article, I discuss secondary predication in Biblical Hebrew, showing that contrary to what linguists such as Rothstein (2004. Structuring events. Malden, MA & Oxford: Blackwell) suggest, there are languages with verb phrases as secondary predicates.

In particular, I deal with a construction in Biblical Hebrew I refer to as the double infinitive-absolute construction, where in addition to a finite verb, the sentence contains two conjoined occurrences of an infinitive absolute, where the first is of the same root and binyan (pattern) as the finite verb but deprived of temporal and agreement features, while the second is of a different root and (maybe) binyan. I show that Biblical Hebrew uses this construction to form a new complex verb with the primary predicate, such that it shares the subject or the object with the primary predicate, depicting a situation that overlaps in time with the situation depicted by the primary predicate or results from it.

Verfahren, Form, Durchsetzung: Die vernachlässigte rechtliche Seite der Wirtschaftsordnung
Authors: Podszun Rupprecht
Published: March 2020

Ökonomische Forschung zu rechtlichen Themen ist häufig stark an den Auswirkungen einer materiell-rechtlichen Regel oder dem Verteilungsergebnis eines Rechtsstreits orientiert. Das wird dem Untersuchungsgegenstand nicht gerecht, da für das Recht der Weg zur Generierung eines solchen materiellen Ergebnisses konstitutiv ist. Interdisziplinäre Forschung muss sich daher auf Verfahren, Form und Durchsetzung ebenso einlassen wie auf materielle Regelungen. Für die Ordnung der Wirtschaft sind dabei die bislang vernachlässigten privatrechtlichen (nicht öffentlich-rechtlichen) Mechanismen besonders interessant: Privatrechtliche Institutionen ordnen das Zusammenleben in ähnlicher Form wie Märkte Angebot und Nachfrage koordinieren. Werden die Eigenrationalitäten des (Verfahrens-)Rechts respektiert, von denen einige im Beitrag vorgestellt werden, kann ökonomische Forschung einen Beitrag zur Lösung zentraler rechtspolitischer Debatten leisten, etwa zur Aufladung privatrechtlicher Mechanismen mit öffentlichen Ordnungsansprüchen zur Verfahrensdauer und zum Zugang zum Recht.
On the Regulation of the International Exchange of Cultural Property
Authors: Groß Steffen W.
Published: March 2020

With its foundation in 1945, UNESCO declared as its main purpose the promotion of international cultural exchange

UNESCO Constitution 1945, Art. I, 2 (c)

. A number of legal instruments (Conventions, Recommendations and Declarations) should duly help to substantiate that general purpose and make it work in practice. In this process, the regulation of the international exchange of cultural property plays a key role. However, the proper regulation of cultural property exchange has been a highly controversial issue. This paper focus on UNESCO's guiding ideas and conceptions of cultural property, international exchange and regulation. The central question is: Are the regulations codified in UNESCO’s Conventions and Recommendations helpful in encouraging international cultural exchange or are we faced, due to the neglect of private agents and the roles they play in cultural exchange, with some sort of one-sided regulation running counter to that aim? The author argues that UNESCO's legal instruments are driven by and express a strong anti-private and anti-market bias, which produce problematic economic incentives in the art and antiquities world to the disadvantage of the international exchange of cultural property.

In den Europawahlen dieses Jahres dominierten, besonders in Deutschland, zwei Themen, derentwegen die künftige Agenda der Europäischen Union wie auch die ungelösten Verfassungsfragen kaum noch Beachtung fanden. Zum einen schien die Gefahr des Rechtspopulismus ein Abwehrbündnis der anderen Parteiengruppen zu erzeugen, das alle sonstigen Differenzen überdeckte. Zum anderen wurde das Konstrukt der Spitzenkandidaten als eine Steigerung der Legitimität präsentiert, ohne zu klären, ob nach der Erweiterung der Europäischen Union noch die Vertiefung, die „ever closer union“ zu erwarten sei, die eine weitere Parlamentarisierung nahelegen könnte. So empfiehlt es sich, die Stadien der europäischen Einigung nachzuvollziehen, die stets hervorgehobene deutsch-französische Achse auch als den deutschen Versuch zu verstehen, Frankreich in den westlichen Strukturen zu halten und schließlich auch zu fragen, wie Europa trotz der sehr unterschiedlichen französischen und deutschen Politikstile und Denkweisen zur Weiterentwicklung westlicher Allianzen beitragen kann.

Basic structures of liquid-vapor separation cooling plates (LSCPs) and a liquid-vapor separation plate condenser (LVSPC) are innovatively designed. Strengthening heat transfer principle of the LSCPs is demonstrated by theoretical analysis. The average condensation heat transfer coefficients (ACHTCs) of the LSCPs are calculated and compared with conventional cooling plate (CCP). Results show that for a laminar flow, the ACHTCs of 2-parts liquid-vapor separation cooling plate and 3-parts liquid-vapor separation cooling plate are respectively 19% and 32% higher than the ACHTCs of the CCP in the same conditions. The ACHTC ratio of N-parts liquid-vapor separation cooling plates (NLSCP) to CCP is $\sqrt[4]{N}$in the same conditions. For a turbulent flow, results show the smaller the height of condensation area, the greater the ACHTCs of cooling plate. In the LVSPC study, operation conditions include the refrigerant R134a mass flux ranging from 22 to 32 kg/(m2.s) and inlet vapor quality from 0.5 to 1 for the saturated temperature of 40∘C. Calculation results showed that the ACHTCs of the LVSPC are 6–24% higher than the ACHTCs of the given common plate condenser (CPC), and similar to the CPC, the ACHTCs of the LVSPC increases with the increase of mass flux and vapor quality.

Subjective vitality is a positive feeling of aliveness and energy, and it is a crucial aspect of well-being. The Subjective Vitality Scales (SVS) have been developed to measure subjective vitality both at the individual difference level and the state level in English-speaking samples. We translated the SVS into German (the SVS-G) and examined their psychometric properties. In Study 1 (N=260), we found that two correlated factors (Factor 1: individual difference level; Factor 2: state level) with five items each constituted a useful structure for the SVS-G. Moreover, the scores on the individual difference scale were more stable than the scores on the state scale. We also found partial evidence for the measurement invariance over a period of three weeks. Conforming to our expectations, Study 2 (N=296) revealed that the SVS-G scores were related to positive and negative affect but could still be distinguished from the affect variables. In line with previous findings, Study 3 (N=203) showed that SVS-G scores are related to well-being variables (happiness and joviality) and the perceived capacity to actively perform effortful tasks (attentiveness and capacity for self-control). Across all the studies, the SVS-G showed satisfying inner consistency, and the two consideration levels (individual differences vs. state) could be differentiated. The initial evidence suggests that overall, the SVS-G have good psychometric properties.
Pyridine-2,6-dicarboxylates in monomeric iron complexes – structural aspects
Authors: Melník Milan , Koman Marian
Published: March 2020

This review includes 70 monomeric high-spin complexes of the following general compositions: [Fe(II)(η3-pdc)(L)3], [Fe(III)(η3-pdc)(L)3]+, [Fe(II)(η3-pdc)2]2− and [Fe(III)(η3-pdc)2]− (pdc = pyridine-2,6-dicarboxylate (−2)). Each Fe(II) atom has a distorted octahedral geometry. The Fe(III) atoms have a distorted octahedral geometry (most common) and in some examples have a distorted pentagonal-bipyramidal geometry. The chelating donor ligands create varieties of n-membered metallocyclic rings: ONO, OCO, NC2N, OC2N, OC2NO and OC3O. Some cooperative effects between Fe(II) and Fe(III) complexes were found and discussed. There are complexes that are examples of distortion isomerism.
Characterization of PVC/MWCNTs Nanocomposite: Solvent Blend

Published: March 2020

Polyvinyl Vinyl Chloride (PVC) multiwall carbon nanotubes (MWCNTs) nanocomposite flexible films were prepared using the solvent blend technique. Chloroform (CHCl3) and tetrahydrofuran ((CH2)4O) were used as solvents for MWCNTs and PVC, respectively. The effect of the solvents’ blend on electrical, optical and thermal properties of PVC/MWCNTs were investigated. The results of the Raman spectrum showed that all the characteristic bands of PVC polymer have a slight shift due to addition of MWCNTs. Electrical results showed that the nanocomposite samples with chloroform volume ratios of 10% and 25% had nearly the same conductivity. This is attributed to the formation of the MWCNTs network, which assisted in electrical conductivity. The I-V hysteresis curve decreases as the temperature increases and as it approaches the glass transition temperature. The non-isothermal kinetics analysis for PVC and PVC/MWCNTs were investigated by Thermogravimetry Analysis (TGA) using the model-free kinetic method. The non-isothermal measurements were carried out at five heating rates of 5 to 40∘C/min. The results show that the main decomposition process has constant apparent activation energies for all samples. The use of the bi-solvent method has improved the dispersion of untreated MWCNTs, and this has been reflected on the stability of both electrical and thermal properties.
Investigation of complex permittivity spectra of foundry sands
Authors: Bifano Luca , Fischerauer Alice , Fischerauer Gerhard
Published: March 2020

This paper discusses impedance spectroscopy as a method to characterize different types of quartz sand, chromite sand, and mixtures of sand. Based on two types of measurement cells, the impedance spectra for various dry sands were measured. The spectra differ enough to allow the sands to be distinguished. The results were validated by extracting the relative permittivity from the impedance and comparing it to literature data. After that, the method could be applied with confidence to other material systems. The influence of moisture was investigated with two types of quartz sand, and typical mixtures of form sand, chromite sand, and regenerated (quartz) sand were studied. In each case, the sand composition had a distinct influence on the Nyquist plot of the impedance spectrum. Compared to results from a laboratory foundry system, the new method exhibits a much more systematic dependence on the sand composition. If one succeeds in describing the impedance spectra with an equivalent circuit model parameterized by only a few parameters, these parameters could be used to identify and classify sand mixtures in the field. This would allow one, for example, to implement feedback control strategies in foundry regeneration processes, which would stabilize the processes and improve the quality of the casting products.
Geographische Handelsforschung im Zeitalter der Digitalisierung: Eine Bestandsaufnahme
Authors: Neiberger Cordula , Mensing Matthias , Kubon Jonas
Published: March 2020

Die Digitalisierung des Handels schreitet seit Mitte der 90erJahre voran, in den letzten 10 Jahren überaus dynamisch. Insbesondere der Onlinehandel steht dabei im Fokus des wissenschaftlichen wie auch des öffentlichen Interesses, wird er doch häufig für das Ladensterben in Mittel- und Kleinstädten verantwortlich gemacht. Umso verwunderlicher ist es, dass zwar die BWL, Informatik, Psychologie und andere Disziplinen eine Unmenge an Arbeiten zu diesem Thema hervorbringt, die Anzahl zumindest der deutschsprachigen geographischen Beiträge hierzu jedoch im Vergleich verschwindend gering scheinen. Dabei ist die Bedeutung raumbezogener Aspekte für die Entwicklung des Handels durchaus groß.

Der Aufsatz hat es sich daher zum Ziel gesetzt, die Erträge der geographischen Forschung zum Thema Digitalisierung des Handels systematisch aufzuarbeiten und dabei die verschiedenen Ansatzpunkte und Blickwinkel zu diskutieren, Defizite aufzuzeigen und weiteren Forschungsbedarf zu formulieren. Dafür wurden insgesamt die rund 53 Beiträge ausgewertet, welche in den sechs wichtigsten deutschsprachigen humangeographischen Zeitschriften, der Reihe „Geographische Handelsforschung“ sowie 12 englischsprachigen humangeographischen Zeitschriften seit Anfang der 90er Jahre zu diesem Thema erschienen sind.
Sexualität und Religion bei jungen Muslim*innen in Deutschland in islamisch-religionspädagogischer Perspektive
Authors: Ulfat Fahimah
Published: March 2020

Das vieldimensionale Thema Sexualität wird in Verbindung mit Religion sehr kontrovers diskutiert. Die klassische Literatur gibt einen Einblick in den offenen Umgang von urbanen Muslim*innen in der Vormoderne (bis etwa 1800) mit dem Thema Sexualität. Im 19. Jahrhundert hat sich allerdings durch die Kolonialisierung ein Wandel vollzogen, der zur Übernahme der viktorianischen Sexualmoral durch Muslim*innen führte. Moderne muslimische Diskurse über Sexualität sind relativ rar. Wie aber lassen sich die Einstellungen heutiger junger Muslim*innen zu Sexualität beschreiben? Einen Einblick in diese Frage können empirische Studien geben, die in diesem Beitrag vorgestellt werden. Sie zeigen, dass die Einstellungen der jungen Muslim*innen zu Sexualität und Geschlechterrollen noch immer tendenziell in den Traditionen und Kulturen ihrer Familien verhaftet sind. Muslimisch-emanzipatorische Diskurse stellen hingegen traditionelle Geschlechterrollen in Frage und dekonstruieren diese. Die Islamische Religionspädagogik kann durch die Entwicklung eines intersektionalen religionspädagogischen Konzepts für die Arbeit mit Gender- und Sexualitätsentwürfen Jugendlicher konstruktiv auf dieses Spannungsverhältnis reagieren.
