Published: June 2020

We aimed to design and validate a new questionnaire of adherence to healthy food pyramid (HFP) (AP-Q), to improve previous instruments. The questionnaire was self-administered and included 28 questions from 10 categories (physical activity, health habits, hydration, grains, fruits, vegetables, oil type, dairy products, animal proteins, and snacks). A population of 130 Spanish adults answered it, obtaining scores from each category and a global score of HFP adherence (AP-Q score). Validation was performed through principal components analysis (PCA) and internal consistency by Cronbach’s alpha. AP-Q was also externally validated with Kidmed-test, answered by 45 individuals from the cohort. The global AP-Q score was 5.1 ± 1.3, with an internal consistency of 64%. The PCA analysis extracted seven principal components, which explained 68.5% of the variance. The global AP-Q score was positively associated with Kidmed-test score. Our data suggest that AP-Q is a complete and robust questionnaire to assess HFP adherence, with several advantages: easy to complete, cost-effective, timesaving and has the competency to assess, besides diet, several features affecting health status, lacking in other instruments. We suggest that AP-Q could be useful in epidemiological research, although it requires additional calibration to analyze its reproducibility and validation in other populations.

Published: June 2020

Device-free localization (DFL) has become a hot topic in the paradigm of the Internet of Things. Traditional localization methods are focused on locating users with attached wearable devices. This involves privacy concerns and physical discomfort especially to users that need to wear and activate those devices daily. DFL makes use of the received signal strength indicator (RSSI) to characterize the user’s location based on their influence on wireless signals. Existing work utilizes statistical features extracted from wireless signals. However, some features may not perform well in different environments. They need to be manually designed for a specific application. Thus, data processing is an important step towards producing robust input data for the classification process. This paper presents experimental procedures using the deep learning approach to automatically learn discriminative features and classify the user’s location. Extensive experiments performed in an indoor laboratory environment demonstrate that the approach can achieve 84.2% accuracy compared to the other basic machine learning algorithms.
Risk Assessment of Seaplane Operation Safety Using Bayesian Network
Authors: Xiao Qin , Luo Fan , Li Yapeng
Published: June 2020

Seaplanes have become popular tourism and transportation tools with the ability of take-off and land on water. Recent seaplane accidents are highlighting the need for safety analysis of the seaplane operation process, which includes the sequential stages of water-taxiing, take-off, flight, and landing. This paper proposes a novel approach to modeling the risk of seaplane operation safety using a Bayesian network (BN). The rough risk factors that may cause seaplane accidents are identified by historical data, literature review, and interviews with experts. Based on the identification result, a risk evaluation indicator system is constructed and screened by the Delphi method. The structure of the proposed BN is derived from the indicator system. The parameter of the BN is obtained by expert experience and parameter learning from statistical data. The BN model is validated with an out-of-sample test demonstrating nearly 95% prediction accuracy of the accident severity level. The model is then applied to conduct diagnosis inference and sensitivity analysis to identify the key risk factors for seaplane operation accidents. The result shows that the four most critical risk factors are mental barrier, mechanical failure, visibility, and improper emergency disposal. It provides an early warning to take appropriate preventive and mitigative measures to enhance the overall safety of the seaplane operation process.
Possible Physical Basis of Mirror Symmetry Effect in Racemic Mixtures of Enantiomers: From Wallach’s Rule, Nonlinear Effects, B–Z DNA Transition, and Similar Phenomena to Mirror Symmetry Effects of Chiral Objects
Authors: Pavlov Valerii A. , Shushenachev Yaroslav V. , Zlotin Sergey G.
Published: June 2020

Effects associated with mirror symmetry may be underlying for a number of phenomena in chemistry and physics. Increase in the density and melting point of the 50%L/50%D collection of enantiomers of a different sign (Wallach’s rule) is probably based on a physical effect of the mirror image. The catalytic activity of metal complexes with racemic ligands differs from the corresponding complexes with enantiomers as well (nonlinear effect). A similar difference in the physical properties of enantiomers and racemate underlies L/D inversion points of linear helical macromolecules, helical nanocrystals of magnetite and boron nitride etc., B–Z DNA transition and phenomenon of mirror neurons may have a similar nature. Here we propose an explanation of the Wallach effect along with some similar chemical, physical, and biological phenomena related to mirror image.
On the Number of Witnesses in the Miller–Rabin Primality Test
Authors: Ishmukhametov Shamil Talgatovich , Mubarakov Bulat Gazinurovich , Rubtsova Ramilya Gakilevna
Published: June 2020

In this paper, we investigate the popular Miller–Rabin primality test and study its effectiveness. The ability of the test to determine prime integers is based on the difference of the number of primality witnesses for composite and prime integers. Let W ( n ) denote the set of all primality witnesses for odd n. By Rabin’s theorem, if n is prime, then each positive integer a < n is a primality witness for n. For composite n, the power of W ( n ) is less than or equal to φ ( n ) / 4 where φ ( n ) is Euler’s Totient function. We derive new exact formulas for the power of W ( n ) depending on the number of factors of tested integers. In addition, we study the average probability of errors in the Miller–Rabin test and show that it decreases when the length of tested integers increases. This allows us to reduce estimations for the probability of the Miller–Rabin test errors and increase its efficiency.
Supersymmetry and Exceptional Points
Authors: Znojil Miloslav
Published: June 2020

The phenomenon of degeneracy of energy levels is often attributed either to an underlying (super)symmetry (SUSY), or to the presence of a Kato exceptional point (EP). In our paper a conceptual bridge between the two notions is proposed to be provided by the recent upgrade of the basic principles of quantum theory called, equivalently, PT − symmetric or three-Hilbert-space (3HS) or quasi-Hermitian formulation in the current physical literature. Although the original purpose of the 3HS approach laid in the mere simplification of technicalities, it is shown here to serve also as a natural theoretical link between the apparently remote concepts of EPs and SUSY. An explicit illustration of their close mutual interplay is provided by the description of infinitely many supersymmetric, mutually non-equivalent and EP-separated regularized spiked harmonic oscillators.
Reed Solomon Coding-Based Medical Image Data Hiding Method against Salt and Pepper Noise
Authors: Konyar Mehmet Zeki , Öztürk Sıtkı
Published: June 2020

Medical data hiding is used to hide patient information inside medical images to protect patient privacy. Patient information in the image should be protected when sending medical images to other specialists or hospitals over the communication network. However, the images are exposed to various unwanted disruptive signals in the communication channel. One of these signals is salt and pepper noise. A pixel exposed to salt and pepper noise becomes completely black or completely white. In pixel-based data hiding methods, it is not possible to extract the secret message in the pixel exposed to this kind of noise. While current data hiding methods are good for many disruptive effects, they are weak against salt and pepper noise. For this reason, the proposed study especially focuses on the accurate extraction of patient information in the salt and pepper noisy medical images. This study was proposed for the most accurate extraction of secret message despite salt and pepper noise, by use of a Reed Solomon error control coding-based data hiding method. The most important feature of Reed Solomon codes is that they can correct errors in non-binary (decimal) numbers directly. Therefore, the Reed Solomon coding-based data hiding method that proposed in this study increases the resistance against salt and pepper noise. Experimental studies show that secret data is accurately extracted from stego images with various densities of salt and pepper noise. Stego medical images created by the proposed method have superior quality values compared to similar literature studies. Additionally, compared to similar methods, the secret message is extracted from the noisy stego image with higher accuracy.

The Fuzzy–AHP Synthesis Model for Energy Security Assessment of the Serbian Natural Gas Sector
Authors: Madžarević Aleksandar R. , Ivezić Dejan D. , Tanasijević Miloš L. , Živković Marija A.
Published: June 2020

Natural gas is used for the production of almost 20% of total energy today. The natural gas security of the Republic of Serbia is an urgent strategic, political and security issue. Serbia is one of the most vulnerable countries in Southeast Europe, because it only has one supply route. This study is a contribution to efforts to better understand the factors affecting energy security through the implementation of a new methodology based on the fuzzy–AHP synthesis model for measuring energy security. This new methodology was used to identify the energy, economic, environmental, social and technical indicators that accompany energy security analysis. The fuzzy–AHP synthesis model uses the asymmetric fuzzy inference approach for an outcome finding with the asymmetric position of fuzzy sets. The most important characteristic of the proposed model is its ability to operate with numerical and linguistic data and universality of application. The result of the proposed model shows a quantified assessment of energy security and its trend in the future of the natural gas sector. It indicates an unacceptably low level of present energy security and a gas system very vulnerable to supply cuts if the current gas infrastructure remains as it is in the future.
Keep a Left Profile, Baby! The Left-Cradling Bias Is Associated with a Preference for Left-Facing Profiles of Human Babies
Authors: Malatesta Gianluca , Marzoli Daniele , Tommasi Luca
Published: June 2020

The left-cradling bias (LCB) refers to the (typically female) preference to hold an infant on the left side of one’s own body. Among the three main accounts proposed for such a phenomenon, namely the “handedness”, “heartbeat” and “hemispheric asymmetry” hypotheses, the latter has met with the greatest empirical success. Accordingly, the LCB would facilitate the communication of socio-emotional information through the right hemisphere of both the cradled and the cradling individual, and should emerge mainly in face-to-face interactions. In this regard, it should be noticed that when the infant’s body is oriented toward the cradler, the left or right side of their face is relatively more visible to left- and right-cradlers, respectively. Therefore, we hypothesized that the LCB might also be associated with a preference for left-facing profiles (i.e., those showing the left, and more expressive, hemiface/cheek) of human babies. In order to test our hypothesis, we assessed the cradling-side preferences of female participants, as well as their preference for the left- or right-facing profile of a human infant depicted in a drawing. Left-cradlers exhibited a significantly larger preference for the left-facing version of the drawing compared with right-cradlers, a finding further corroborating the right-hemisphere hypothesis.

Published: June 2020

Although d,l-amino acids are symmetrical molecules, l-isomers are generally dominant in living organisms. However, it has been found that some d-amino acids also have biological functions. A new method for simultaneously analyzing d,l-amino acids in biological samples is required to allow unknown functions of d-amino acids to be investigated. d-Amino acids in urine are currently receiving increasing amounts of attention, particularly for screening for chronic kidney diseases. However, simultaneously analyzing d,l-amino acids in human urine is challenging because of interfering unknown compounds in urine. In this study, the axially chiral derivatizing agent (R)-4-nitrophenyl-N-[2-(diethylamino)-6,6-dimethyl-[1,1-biphenyl]-2-yl] carbamate hydrochloride was used to allow enantiomers of amino acids in human urine to be simultaneously determined by liquid chromatography electrospray ionization tandem mass spectrometry. The optimized method gave good linearities, precision results, and recoveries for 18 proteinogenic amino acids and their enantiomers and glycine. The chiral-switching method using (S)-4-nitrophenyl-N-[2-(diethylamino)-6, 6-dimethyl-[1,1-biphenyl]-2-yl]carbamate hydrochloride confirmed the expected concentrations of 32 of the 37 analytes. The method was successfully used to determine the concentrations of d-serine, d-alanine, d-asparagine, d-allothreonine, d-lysine, and the d-isomers of 10 other amino acids in five human volunteer urine samples.

Published: June 2020

Genotype VII Newcastle disease viruses are associated with huge economic losses in the global poultry industry. Despite the intensive applications of vaccines, disease outbreaks caused by those viruses continue to occur frequently even among the vaccinated poultry farms. An important factor in the suboptimal protective efficacy of the current vaccines is the genetic mismatch between the prevalent strains and the vaccine strains. Therefore, in the present study, an effective and stable genotype-matched live attenuated Newcastle disease virus (NDV) vaccine was developed using reverse genetics, based on a recently isolated virulent naturally recombinant NDV IBS025/13 Malaysian strain. First of all, the sequence encoding the fusion protein (F) cleavage site of the virus was modified in silico from virulent polybasic (RRQKRF) to avirulent monobasic (GRQGRL) motif. The entire modified sequence was then chemically synthesized and inserted into pOLTV5 transcription vector for virus rescue. A recombinant virus termed mIBS025 was successfully recovered and shown to be highly attenuated based on OIE recommended pathogenicity assessment indices. Furthermore, the virus was shown to remain stably attenuated and retain the avirulent monobasic F cleavage site after 15 consecutive passages in specific-pathogen-free embryonated eggs and 12 passages in one-day-old chicks. More so, the recombinant virus induced a significantly higher hemagglutination inhibition antibody titre than LaSota although both vaccines fully protected chicken against genotype VII NDV induced mortality and morbidity. Finally, mIBS025 was shown to significantly reduce both the duration and quantity of cloacal and oropharyngeal shedding of the challenged genotype VII virus compared to the LaSota vaccine. These findings collectively indicate that mIBS025 provides a better protective efficacy than LaSota and therefore can be used as a promising vaccine candidate against genotype VII NDV strains.
Highly Saline Water Desalination Using Direct Contact Membrane Distillation (DCMD): Experimental and Simulation Study
Authors: Ameen Noor A. Mohammad , Ibrahim Salah S. , Alsalhy Qusay F. , Figoli Alberto
Published: June 2020

The path for water molecules transported across a membrane in real porous membranes has been considered to be a constant factor in the membrane distillation (MD) process (i.e., constant tortuosity); as such, its effect on membrane performance at various operating conditions has been ignored by researchers. Therefore, a simultaneous heat and mass transfer model throughout the direct contact membrane distillation (DCMD) module was developed in this study by taking into account the hypothetical path across the membrane as a variable factor within the operating conditions because it exhibits the changes to the mass transfer resistance across the membrane under the DCMD run. The DCMD process was described by the developed model using a system of nonlinear equations and solved numerically by MATLAB software. The performance of the poly-tetra-fluoroethylene (PTFE) membrane was examined to treat 200 g/L NaCl saline at various operating conditions. The simulation results in the present work showed that the hypothetical proposed path across the membrane has a variable value and was affected by changing the feed temperature and feed concentration. The results estimated by the developed model showed an excellent conformity with the experimental results. The salt rejection remained high (greater than 99.9%) in all cases. The temperature polarization coefficient for the DCMD ranged between 0.88 and 0.967, and the gain output ratio (GOR) was 0.893. The maximum thermal efficiency of the system was 84.5%.
Application of Multivariate Statistical Analysis in the Development of a Surrogate Water Quality Index (WQI) for South African Watersheds
Authors: Banda Talent , Kumarasamy Muthukrishnavellaisamy
Published: June 2020

Water quality indices (WQIs) are customarily associated with heavy data input demand, making them more rigorous and bulky. Such burdensome attributes are too taxing, time-consuming, and command a significant amount of resources to implement, which discourages their application and directly influences water resource monitoring. It is then imperative to focus on developing compatible, simpler, and less-demanding WQI tools, but with equally matching computational ability. Surrogate models are the best fitting, conforming to the prescribed features and scope. Therefore, this study attempts to provide a surrogate WQI as an alternative water quality monitoring tool that requires fewer inputs, minimal effort, and marginal resources to function. Accordingly, multivariate statistical techniques which include principal component analysis (PCA), hierarchical clustering analysis (HCA) and multiple linear regression (MLR) are applied primarily to determine four proxy variables and establish relevant model coefficients. As a result, chlorophyll-a, electrical conductivity, pondus Hydrogenium and turbidity are the final four proxy variables retained. A vital feature of the proposed surrogate index is that the input parameters qualify for inclusion into remote monitoring systems; henceforth, the model can be applied in remote monitoring programs. Reflecting on the model validation results, the proposed surrogate WQI is considered scientifically stable, with a minimum magnitude of divergence from the ideal water quality values. More importantly, the model displayed a predictive pattern identical to the ideal graph, matching on both index scores and classification values. The established surrogate model is an important milestone with the potential of promoting water resource monitoring and assisting in capturing of spatial and temporal changes in South African river catchments. This paper aims at outlining the methods used in developing the surrogate water quality index and document the results achieved.

Authors: Burman Anton J. , Andersson Anders G. , Hellström J. Gunnar I. , Angele Kristian
Published: June 2020

The operating conditions of Nordic hydropower plants are expected to change in the coming years to work more in conjunction with intermittent power production, causing more frequent hydropeaking events. Hydropeaking has been shown to be detrimental to wildlife in the river reaches downstream of hydropower plants. In this work, we investigate how different possible future hydropeaking scenarios affect the water surface elevation dynamics in a bypass reach in the Ume River in northern Sweden. The river dynamics has been modeled using the open-source solver Delft3D. The numerical model was validated and calibrated with water-surface-elevation measurements. A hysteresis effect on the water surface elevation, varying with the downstream distance from the spillways, was seen in both the simulated and the measured data. Increasing the hydropeaking rate is shown to dampen the variation in water surface elevation and wetted area in the most downstream parts of the reach, which could have positive effects on habitat and bed stability compared to slower rates in that region.

MODES OF RELIGIOUS SELF-REPRESENTATION ON THE EXAMPLE OF GOTTSCHALK OF ORBAIS: IN THE QUEST FOR GOTTSCHALK’S MODELS
Authors: Radovanović Bojana
Published: June 2020

Gottschalk of Orbais (ca. 804–868) was condemned for heresy by the Synods of Mainz and Quirzey (in 848 and 849) due to his doctrine of double predestination, and spent the last twenty years of his life in confinement in Hautvillers. Throughout Gottschalk’s last years, and perhaps due to the severe punishment he had suffered, another facette of this monachus gyrovagus surfaced. The image of a rebellious figure, somewhat subversive in his heretical self-defence, resorting to subterfuge, and endowed with protruding features, announcing the penchant to martyrium, prophecy and some uncommon strategies of religious self-representation for the Carolingian era, came to light.

Београдски казнени завод, основан 1868. на простору Београдске тврђаве, деценијама је представљао централну институцију за издржавање казне робије у Србији. Робијаши затворени на том простору, били су подвргнути систему заједничког затвора који је установљен у казаматима саме тврђаве. Током наредних година било је покренуто неколико покушаја реформе, као и увођења новог система ћелијског затвора, који би заменио већ застарели систем заједничког затвора, какав је постојао у претходном периоду. Међутим, услед знатних трошкова које би такав подухват захтевао, као и неслагања око начина спровођења саме казнене политике, та идеја упорно је одлагана све до почетка Првог светског рата. Тако су, уместо у новом казненом заводу, српски робијаши и даље остали утамничени у казаматима древне Београдске тврђаве.

This study aims to analyze the effect of cash flow from operating activities, investment activities, funding activities that have an impact on stock prices and analyze the effect of cash flows from operating activities, investment activities, funding activities simultaneously affecting stock prices. Data analysis methods used are quantitative descriptive analysis and multiple regression analysis.

Based on the results of a partial test, the effect of cash flow from operating activities on stock prices has a positive and significant effect, thus the first hypothesis is accepted. Based on the results of a partial test between investment cash flow to stock prices, it was found that cash flow from investment activities was not significant, thus the second hypothesis was rejected. Based on the results of a partial test between the cash flows of funding activities against the stock price, it was found that the funding cash flow was not significant. This can be interpreted that the funding cash flow has no effect on stock prices, thus the third hypothesis is rejected. And the results of simultaneous tests prove that there is a simultaneous influence between cash flow operating activities, investment activities and funding activities on stock prices.

Rainwater harvesting system (RWH) implementation may be a solution to maximize the water availability and reduce the runoff volume in Palembang City. For successful implementation, it is necessary to identify potential areas for RWH implementation. This study aims to identify areas in Palembang that are potential for implementing the RWH system. An analysis of parameters that affect the classification also conducted. This study used a geographic information system (GIS) approach using rainfall, slope, land use, and soil type parameters which are structured in a hierarchy using the analytical hierarchy process (AHP). Based on the weighted overlay method, it can be concluded that  a very potential area for RWH implementation dominated with a wet area, flat slope, dense residential area and the type of soil which is not susceptible to infiltration. Whereas the medium and non-potential areas are dominated by steep and very steep slopes as well as unoccupied land use. Areas of high potential and potential reach 18.17% and 66.14% respectively. While the medium and not the potential is 13.66% and 2.03%. Areas of great potential are in the Buah, Kidul, Sekanak, Sriguna, Bendung, and Selinca Sub Watershed. Non-potential areas are only available in small area in DAS Gandus, Gasing, and Lambidaro Sub Watershed.

Published: June 2020

İnsanlar, seçme şanslarının olduğu her fırsatta ilk başta doğal kökenli ürünleri tercih etmektedirler. Bunun asıl sebebi ise kimyasal kökenli ürünlerin sağlığa olan olumsuz etkileridir. Bu bağlamda, yapılan bu çalışmada keten kumaşların ısırgan otu ile boyanabilirliğinin araştırılması amaçlanmıştır. Isırgan otu kuru halde temin edildikten sonra değirmenden geçirilerek öğütülmüş ve boyama denemelerinde öğütülmüş olan bu kısım kullanılmıştır. Boyamada 6 farklı metal tuzu mordan maddesi olarak kullanılmıştır. Ayrıca mordan maddesi kullanımı olmadan da boyama denemeleri gerçekleştirilmiştir. Kullanılan bu 6 farklı mordan maddesi ise; Potasyum alüminyum sülfat (Şap) (KAlSO4.10H2O), çinko klorür (ZnCl2), potasyum dikromat (K2Cr2O7), demir II sülfat (FeSO4.7H2O), kalay II klorür (SnCl2.2H2O), bakır II sülfat (CuSO4.5H2O) dır. Boyama işlemleri tamamlandıktan sonra boyanmış olan kumaş numunelerinin spektrofotometre yardımıyla CIELAB (L*, a*, b*, C* ve h°) ve K/S değerleri ölçülmüştür. Ayrıca boyanmış olan kumaş numunelerinin yıkama ve ışık haslığı testleri de yapılmıştır. Bu işlemler sonucunda ısırgan otunun keten kumaşların renklendirilmesinde kullanılabileceği tespit edilmiştir.
Reflexiones en torno al abordaje del Turismo en el nivel universitario. La experiencia de la Licenciatura en Turismo de la UNR
Authors: Perotti Sofía
Published: June 2020

Extracto de texto: "En septiembre de 2017 el Consejo Superior de la Universidad Nacional de Rosario (UNR) aprobó la creación de la Licenciatura en Turismo. La misma constituye la primera experiencia de formación universitaria de carácter público en este campo disciplinar, en la Provincia de Santa Fe. Un territorio provincial que, así como la propia ciudad de Rosario, han ido posicionándose como destinos turísticos en procesos de política pública que se han desarrollado de la mano de transformaciones urbanísticas, productivas, tecnológicas, pero también en los imaginarios de la población local, respecto de la actividad turística y sus potencialidades. En estos lugares, hasta el momento sólo existían posibilidades de formación en el nivel terciario, de carácter privado, con una aproximación al fenómeno turístico casi exclusivamente desde su perspectiva comercial. En este marco, el diferencial de la formación propuesta en la UNR tiene que ver con incorporar de manera central la perspectiva de las ciencias sociales, a partir de ejes clave para el pensamiento social, como la cultura, los derechos, el desarrollo, el territorio, las políticas públicas, las relaciones internacionales, la mediación tecnológica, el ambiente, la perspectiva de género, la diversidad sexual. Estos aspectos no excluyen la consideración del turismo como una industria en expansión a nivel global, sino que complementan y enriquecen el abordaje de dicho fenómeno, en un sentido interdisciplinario. Asimismo, la carrera cuenta con una particularidad dentro de la UNR, ya que es la primera propuesta académica de grado que depende de dos Facultades -Ciencia Política y Relaciones Internacionales y Ciencias Económicas y Estadística-. En este sentido, el proyecto ha cimentado durante su planificación e implementación una notable impronta de cultura colaborativa, diálogo institucional e interdisciplina..."

Objective. To increase efficiency of cavitary pulmonary tuberculosis treatment by developing modern indications and technology of extrapleural pneumolysis with filling material.

Material and methods. We reviewed 25 patients with cavitary pulmonary tuberculosis and bacterial excretion who had undergone extrapleural pneumolysis with different types of filling material in 2004–2015. In 16 cases, we performed surgery in patients with one lung.

Results. 56% of operated patients demonstrated extensively drug-resistant TB, 40% had multidrug-resistant TB. Cavities were closed and bacterial excretion ceased in 92% of patients at discharge. Long-term results with observation period from 1 to 12 years were analyzed in 24 patients, 17 (71%) of them had complete clinical efficacy.

Conclusion. Extrapleural pneumolysis is a mini-invasive surgical treatment that can prove positive effect in patients with non-fibrotic changes in a cavity wall and pathological process in upper parts of the lungs.
