Rejoinder to Dominiak on the necessity of easements
Authors: Block Walter E.
Published: December 2021

Dominiak (2019) agrees with the Blockian proviso: homesteading in a bagel or donut format is illicit, since it allows the owner to control land (the hole, the territory in the middle) with which he has not mixed his labor. Thus, a person who does so must open up an easement allowing outside home-steaders through his property, and into this so-far virgin land. But, this author claims this proviso of Block’s does not go far enough. It should also be extended further, not only to incorporate the bagel format, but also in justiﬁcation of easements through private property in emergencies, and so as to avoid entrapment. I strongly support Dominiak in his defense of the Blockian proviso against critics (Kinsella, 2007, 2009C) in the ﬁrst part of his excellent paper, but ﬁnd I cannot agree with this second contention of his. In short, Dominiak agrees with Block regarding easements in the bagel case, but wants to extend this concept to when property owners are encircled, and thus trapped. In my view, extending easements to cases other than the bagel is incompatible with libertarianism’s emphasis on the sanctity of private property rights. Certain positive rights (to, in this case, movement) are essential to Dominiak’s argument. And these rights do not exist. Therefore, Dominiak’s argument is unsound.
Libertarian easements revisited
Authors: Dominiak Łukasz
Published: December 2021

In the present paper, I develop further my original argument for extending the Blockian Proviso to landlocked property. I use Walter Block’s newest rejoinder as an opportunity to generalize my case for necessity easements. I argue that in order to attenuate various conﬂicts of rights, libertarianism should interpret its thesis that property rights are absolute in a less demanding way.
Znajomość zasad gwarantowania depozytów a skłonność do runu na banku
Authors: Kurowski Łukasz , Górski Piotr
Published: December 2021

The main goal of the deposit guarantee scheme is to prevent banking panic and consequently to prevent banking crises. The purpose of the article is to check whether the knowledge of depositors about the existence of a deposit guarantee scheme and about the terms of the guarantee aﬀects the propensity to bank run. Thus, the presented study emphasizes that the eﬀectiveness of the deposit guarantee scheme is dependent on the degree of knowledge about the principles of its functioning in society. The results of 200 CATI interviews suggest that this knowledge does not aﬀect the decision to run on a bank, but determines the run type. People with higher knowledge about the principles of deposit guarantee are more likely to make a non-cash form of run (transfer of funds to another bank). For people with less knowledge the cash withdrawal is dominant. Due to the ﬁnite cash resources in bank branches, the cash withdrawal form can increase the scale of the run through its mediality.
Comparison of the Occlusal Feature Index (OFI) and Dental Aesthetic Index (DAI) in 10–14-year-old children at the Universitas Sumatera Utara Dental Hospital
Authors: Lubis Hilda Fitria , Azriana Arfah
Published: December 2021

Background: Malocclusion often occurs in children due to discrepancies between primary teeth and permanent teeth. An assessment of the severity of the malocclusion is necessary for establishing the diagnosis and determining the need for treatment. The Occlusal Feature Index (OFI) and Dental Aesthetic Index (DAI) are indices that assess the need for orthodontic treatment, but they use different weights. Purpose: This study aimed to compare the need for orthodontic treatment based on the OFI and DAI in 10–14-year-old children. Methods: The sample in this study is secondary data in the form of 66 study models pre-treatment in children aged 10–14 years at the Universitas Sumatra Utara (USU) Dental Hospital. All samples were collected based on inclusion and exclusion criteria. The measurement results were analysed statistically by the Chi-square test to see the comparison between the OFI and DAI. The results obtained are presented in the form of frequency and percentage. Results: For the OFI, 42.4% of the samples had no orthodontic treatment needed, 31.8% were indicated to treat, and 25.8% require mandatory treatment. For the DAI, 47% of samples had no/little treatment need, 25.8% had elective treatment need, 16.7% had treatment considered mandatory, and 10.6% treatment highly desirable. Based on the assessment to compare the OFI and DAI using the Chi-square test, p=0.001 was obtained. Conclusion: There was a significant difference in the need for orthodontic treatment between OFI and DAI in children aged 10–14 years at the USU Dental Hospital.

Authors: Jazaldi Fadli , Soegiharto Benny M. , Hutabarat Astrid Dinda , Soedarsono Noertami , Auerkari Elza Ibrahim
Published: December 2021

Background: Class II malocclusion is one of the main orthodontic issues for patients in seeking treatment. The prevalence of class II malocclusion varies in different populations. Variation in skeletal profile is mainly controlled internally by a regulatory gene. Runt-related transcription factor-2 (Runx2) plays a role in osteoblast differentiation and is highly expressed during development. Purpose: This study aimed to evaluate the relation of regulatory gene variation in the Runx2 promoter with class II malocclusion. Methods: DNA samples were acquired from 95 orthodontic patients in Jakarta, Indonesia, who were divided into two groups: class I skeletal malocclusion (control group) and class II malocclusion. A single nucleotide polymorphism was investigated using the polymerase chain reaction and restriction fragment length polymorphism techniques. The distribution of alleles was assessed using the Hardy-Weinberg test. The relationship between polymorphism and skeletal variation was assessed with the Chi-Square test and logistic regression. Results: The frequency distributions of genotypes and alleles were tested for Hardy-Weinberg equilibrium and found to be slightly deviated. There was an equal distribution of G and T alleles throughout class II and class I skeletal malocclusions and the Chi-Square test showed that this relationship was not significant (p=0.5). Conclusion: Runx2 rs59983488 polymorphism was found in the Indonesian subpopulation; however, an association between Runx2 rs59983488 polymorphism and class II skeletal malocclusion was not found.

Authors: Sani Imelia Arifatus , Cahyani Siska Maulidina , Fariha Safira , Oliresianela O. , Diah D.
Published: December 2021

Background: In Indonesia, the prevalence of dental and oral problems is still high at 57.6% in 2018, especially periodontitis at 74.1%. Peptidoglycan is an essential component of the bacterial cell wall. Peptidoglycan glycosyltransferase (PGT) is a protein target that plays a role in transferring lipid disaccharides II to growing glycan chains for bacterial cell wall synthesis. Propolis is a natural ingredient produced by bees and has anti-inflammatory, antibacterial, antiviral and antioxidant properties so that it has the potential to be a natural mouthwash ingredient. One of the antibacterial properties of propolis is to be able to kill and reduce the number of bacteria that cause periodontitis. Purpose: This study aims to investigate the potential of a specific compound of propolis as an inhibitor of protein peptidoglycan glycosyltransferase through bonding interactions. Methods: The method used is an in-silico test in molecular docking with computational software, namely Molegro virtual docker and Discovery Studio visualizer. Results: This study showed the types of bonds between the four compounds, and chlorhexidine as a control showed similar types of bonds, including hydrogen bonds, hydrophobic interactions and unfavourable bonds. The binding energy values of each of the five compounds were pinocembrin -222.166 kJ/mol, hesperetin -230.144 kJ/mol, chrysin -219.45 kJ/mol, caffeic acid phenethyl ester -266.64 kJ/mol and chlorhexidine -362.71 kJ/mol. Conclusion: Caffeic acid phenethyl ester (CAPE) is the most significant potential as an inhibitor of protein peptidoglycan glycosyltransferase and chlorhexidine has the highest binding affinity than the four propolis compounds, followed by caffeic acid phenethyl ester in propolis in silico.

Islam has comprehensive rule that regulate in all aspects of human life, including evireonmental issues. One fact of global problems related to environment is waste management problem. Zero waste is waste management system which it could be a holistic solution due to waste issue. This study aim to analyse the zero waste concept within Islamic-science prespective on municipal waste reduction as a solution to prevent environmental damage. This study use literature reviews method that focuse on waste management programs in Surabaya City which have been stated on a national and international scale. The results of this study show implementation of waste management programs In Surabaya City such as the depletion of disposable plastic usage, the existence of waste bank units, until the presence of a solid waste power plant infrastructure. However, the program implementation has not been able to decrease the number of resource in Surabaya landfill. It is because of poorly coordination between government and society, and the lack of environmental awareness about the harm of waste resource to environmental health. Thus, the existence of zero waste concept combined with Islamic-science prespective could lead direction movement to appreciate the importance of proper and correct waste management. Based on these results, it conclude that waste management with zero waste concept considered to become a new lifestyle in waste management namely Islamic lifestyle, because it is in line with Islamic law. Moreover, this new lifestyle could be implemented in all communities regarding to the nature is a gift form Allah SWT and humans have a command to protect it.

OPTIMAL CONSTRUCTION OF THE PATTERN MATRIX FOR PROBABILISTIC NEURAL NETWORKS IN TECHNICAL DIAGNOSTICS BASED ON EXPERT ESTIMATIONS
Authors: Romanuke Vadim
Published: December 2021

In the field of technical diagnostics, many tasks are solved by using automated classification. For this, such classifiers like probabilistic neural networks fit best owing to their simplicity. To obtain a probabilistic neural network pattern matrix for technical diagnostics, expert estimations or measurements are commonly involved. The pattern matrix can be deduced straightforwardly by just averaging over those estimations. However, averages are not always the best way to process expert estimations. The goal is to suggest a method of optimally deducing the pattern matrix for technical diagnostics based on expert estimations. The main criterion of the optimality is maximization of the performance, in which the subcriterion of maximization of the operation speed is included. First of all, the maximal width of the pattern matrix is determined. The width does not exceed the number of experts. Then, for every state of an object, the expert estimations are clustered. The clustering can be done by using the k-means method or similar. The centroids of these clusters successively form the pattern matrix. The optimal number of clusters determines the probabilistic neural network optimality by its performance maximization. In general, most results of the error rate percentage of probabilistic neural networks appear to be near-exponentially decreasing as the number of clustered expert estimations is increased. Therefore, if the optimal number of clusters defines a too “wide” pattern matrix whose operation speed is intolerably slow, the performance maximization implies a tradeoff between the error rate percentage minimum and maximally tolerable slowness in the probabilistic neural network operation speed. The optimal number of clusters is found at an asymptotically minimal error rate percentage, or at an acceptable error rate percentage which corresponds to maximally tolerable slowness in operation speed. The optimality is practically referred to the simultaneous acceptability of error rate and operation speed.

Published: December 2021

A identidade é um conceito consagrado há bastante tempo nas Ciências Sociais. Do essencialismo ao construtivismo, teóricos construíram explicações para a identidade no cenário de virada da modernidade para a assim chamada pós-modernidade. Na Geografia, a perspectiva aberta por conceitos-chave mobilizados por essa ciência, como espaço, território, lugar e paisagem, tem permitido um privilegiado olhar sobre a formação da identidade. Propõe-se aqui revisitar as principais concepções propostas. A análise apresentada é de cunho qualitativo e realizada com base em pesquisa bibliográfica. Os resultados apontam para a importância da análise geográfica nesse contexto. O acelerado processo de globalização nas últimas décadas implicou na revalorização do espaço e no redimensionamento de sua importância para a constituição das identidades.

Authors: Ferreira Dias Franciele Miranda , Dantas Rafael
Published: December 2021

O objetivo do trabalho é discutir e caracterizar, quanto aos aspectos econômicos, duas pequenas cidades da Região Centro-Oeste paulista: 1) Canitar, cidade atrelada ao setor sucroalcoleiro e que tem-se transformado recentemente em uma cidade-dormitório; 2) Águas de Santa Bárbara, caracterizada como estância hidromineral. O estudo parte da análise da pequena cidade, escalão urbano ainda pouco estudado, buscando contribuir com a compreensão de seus diferentes significados. A partir da consulta ao arcabouço bibliográfico e à pesquisa em ambas cidades, em junho de 2018, constituída por entrevistas, registro fotográfico e coletas de dados, concluiu-se que apesar de serem pequenas cidades localizadas na mesma região do estado de São Paulo, diferenciam-se quanto aos elementos econômicos e sociais, na medida que Canitar representa a pequena cidade inserida na agricultura capitalista e  Águas de Santa Bárbara, apesar de pautar sua economia no turismo de águas termais, passa por um processo de declínio dessa atividade, resultando em desdobramentos econômicos e sociais.

Published: December 2021

This text, critically addresses, the issue of education management in order to apprehend elements of a formative planning process based on the relationship between the Secretariat's Action Plan and the Municipal Education Plan (PME) and Political Pedagogical Project instruments. In general, we can declare that the principles of democratic management and participation are basic elements in a planning process for these instruments and that, according to the consonance of subnational plans with the National Education Plan, they are also articulators of education in the municipality. The data analyzed make it possible to indicate that the Secretariat's Action Plan planning process is developed in a distinct and disputed manner, with the idea of a plan standing out as an end in itself and without articulation.
On the Quark Scaling Theorem and the Polarisable Dipole of the Quark in a Scalar Field
Authors: Roza Engel
Published: December 2021

In this article the possible impact on the present state of particle physics theory is discussed of two unrecognized theoretical elements. These elements are the awareness that (a) the quark is a Dirac particle with a polarisable dipole moment in a scalar field and that (b) Dirac’s wave equation for fermions, if derived from Einstein’s geodesic equation, reveals a scaling theorem for quarks. It is shown that recognition of these elements proves by theory quite some relationships that are up to now only empirically assessed, such as for instance, the mass relationships between the elementary quarks, the relationship between the bare mass and the constituent mass of quarks, the mass spectrum of hadrons and the mass values of the Z boson and the Higgs boson.

Published: December 2021

Avian mutations in vaccine strains obtained from embryonated eggs could impair vaccine effec-tiveness. We performed a systematic review and meta-analysis of the adjusted relative vaccine effectiveness (arVE) of seed cell-cultured influenza vaccines (ccIV) compared to egg-based influ-enza vaccines (eIV) in preventing laboratory-confirmed influenza related outcomes (IRO) or IRO by clinical codes, in subjects 18 and over. We completed the literature search in January 2021; ap-plied exclusion criteria, evaluated risk of bias of the evidence, and performed heterogeneity, pub-lication bias, qualitative, quantitative and sensitivity analyses. All estimates were computed us-ing a random approach. International Prospective Register of Systematic Reviews, CRD42021228290. We identified 12 publications that reported 26 adjusted arVE results. Five publications reported 13 laboratory confirmed arVE and seven reported 13 code-ascertained arVE. Nine publications with 22 results were at low risk of bias. Heterogeneity was explained by season and risk of bias. We found a significant 11% (8 to 14%) adjusted arVE favoring ccIV in preventing any IRO in the 2017-2018 influenza season. The arVE was 3% (-01 to 7%) in the 2018-2019 influenza season. We found moderate evidence of a significant advantage of the ccIV in preventing IRO, compared to eIV, in a well-matched A(H3N2) predominant season.
Integrated Watershed Management Framework and Groundwater Resources in Africa- A Review of West Africa Sub-region
Authors: Adesina John Adekunle , Jiang Jiang , Xiaolan Tang
Published: December 2021

Human activities mostly impact the trend and direction of surface water, groundwater, and other river basin resources in the watershed in Africa. Human activities influence river flows and the water quality at both highlands and lowlands. A watershed is indeed a conserved area of land that collects rain and snow and empties or penetrates into ground water sources. The act of managing the activities around the watershed is the Integrated Watershed Management while considering the social, economic, and environmental issues, as well as community interests to manage water resources sustainably. These watersheds, river basins, and groundwater resources provide important services for communities and biodiversity. This paper reveals that the best way to protect groundwater resources is on a watershed basis using IWM. This technique enables us to handle a variety of concerns and objectives while also allowing us to plan in a complicated and uncertain environment. IWM involves cooperation and participation from a wide range of community interests and water users, including municipalities, companies, people, agencies, and landowners, for stakeholders' input to be successful. All of the strategies and plans are produced concerning one another, as well as the overall conditions of the watershed, local land uses, and specific issues.
A Microfluidic Dielectric Spectroscopy System for Characterization of Biological Cells in Physiological Media
Authors: Bakhtiari Shide , D. Manshadi Mohammad K. , Mansoorifar Amin , Beskok Ali
Published: December 2021

Dielectric spectroscopy (DS) is a promising cell screening method that can be used for diagnostic and drug discovery purposes. The primary challenge of using DS in physiological buffers is the electrode polarization (EP) that overwhelms the impedance signal within a large frequency range. These effects further amplify with miniaturization of the measurement electrodes. In this study, we present a microfluidic system and the associated equivalent circuit models for real-time measurements of cell membrane capacitance and cytoplasm resistance in physiological buffers with 10s increments. The current device captures several hundreds of biological cells in individual microwells through gravitational settling and measures the system’s impedance using microelectrodes covered with dendritic gold nanostructures. Using PC-3 cells (a highly metastatic prostate cancer cell line) suspended in cell growth media (CGM), we demonstrate stable measurements of cell membrane capacitance and cytoplasm resistance in the device for over 15 minutes. We also describe a consistent application of the equivalent circuit model, starting from the reference measurements used to determine the system parameters. The circuit model is tested using devices with varying dimensions, and the obtained cell parameters between different devices are nearly identical. Further analyses of the impedance data have shown that accurate cell membrane capacitance and cytoplasm resistance can be extracted using a limited number of measurements in the 5 MHz to 10 MHz range. This will potentially reduce the timescale required for real-time DS measurements below 1s. Overall the new microfluidic device can be used for dielectric characterization of biological cells in physiological buffers for various cell screening applications.
Main Challenges and Opportunities in Higher Education to Promote Sustainable Development Goals. The Effectiveness of Digital Teaching Methods in Times of COVID-19
Authors: Lopez Belen
Published: December 2021

The Coronavirus (COVID-19) pandemic has created big challenges and opportunities in Higher Education (HE). In this situation, several universities worldwide have responded with digital methods and hybrid classes in a short period of time. The aim of this paper is to show how the universities have adapted teaching methods to digital platforms in the academic year 2020–21. This case study is based on the experience of 37 postgraduate communication students in the course Business and Communication from a Communication Programme. The objective of this course was to promote the 17 sustainable development goals (SDGs) in business and following the Principles for Responsible Management Education (PRME) of the United Nations. To do this, the students provided different solutions related to the SDGs and developed a communication strategy to inform and engage the stakeholders in the companies analyzed in a hybrid class. The results show that using this methodology and working in digital platforms, students have learned the importance of SDGs through implementing specific solutions linked to the corporate social responsibility (CSR) strategy. Based on this analysis, they also developed a communication strategy showing how companies can improve society with specific actions through the lens of the SDG perspective.
Approximating the Steady-state Temperature of 3D Electronic Systems with Convolutional Neural Networks
Authors: Stipsitz Monika , Sanchis-Alepuz Hèlios
Published: December 2021

Thermal simulations are an important part in the design of electronic systems, especially as systems with high power density become common. In simulation-based design approaches, a considerable amount of time is spent by repeated simulations. In this work, we present a proof-of-concept study of the application of convolutional neural networks to accelerate those thermal simulations. The goal is not to replace standard simulation tools but to provide a method to quickly select promising samples for more detailed investigations. Based on a training set of randomly generated circuits with corresponding Finite Element solutions, the full 3D steady-state temperature field is estimated using a fully convolutional neural network. A custom network architecture is proposed which captures the long-range correlations present in heat conduction problems. We test the network on a separate dataset and find that the mean relative error is around 2 % and the typical evaluation time is 35 ms per sample ( 2 ms for evaluation, 33 ms for data transfer). The benefit of this neural-network-based approach is that, once training is completed, the network can be applied to any system within the design space spanned by the randomised training dataset (which includes different components, material properties, different positioning of components on a PCB, etc.).
Change of Persistence in European Electricity Spot Prices
Authors: Rydin Gorjão Leonardo , Witthaut Dirk , Lind Pedro G. , Medjroubi Wided
Published: December 2021

The European Power Exchange has introduced day-ahead auctions and continuous trading spot markets to facilitate the insertion of renewable electricity. These markets are designed to balance excess or lack of power in short time periods, which leads to a large stochastic variability of the electricity prices. Furthermore, the different markets show different stochastic memory in their electricity price time series, which seem to be the cause for the large volatility. In particular, we show the antithetical temporal correlation in the intraday 15 minutes spot markets in comparison to the day-ahead hourly market. We contrast the results from Detrended Fluctuation Analysis (DFA) to a new method based on the Kramers–Moyal equation in scale. For very short term (< 12 hours), all price time series show positive temporal correlations (Hurst exponent H > 0.5) except for the intraday 15 minute market, which shows strong negative correlations (H < 0.5). For longer term periods covering up to two days, all price time series are anti-correlated (H < 0.5).
The Role of Diet in Prognosis among Cancer Survivors: A systematic Review and Meta-Analysis of Dietary Patterns and Diet Interventions
Authors: Castro-Espin Carlota , Agudo Antonio
Published: December 2021

Cancer survival continues to improve in high-income countries, partly explained by advances in screening and treatment. Previous studies have mainly examined the relationship between individual dietary components and cancer prognosis in tumours with good therapeutic response (breast, colon and prostate cancers). The aim of this review was to assess qualitatively (and quantitatively where appropriate) the associations of dietary patterns and cancer prognosis from published prospective cohort studies, as well as the effect of diet interventions by means of randomized controlled trials (RCT). A systematic search was conducted in PubMed, and a total of 35 prospective cohort studies and 14 RCT published between 2011 and 2021 were selected. Better overall diet quality was associated with improved survival among breast and colorectal cancer survivors; adherence to the Mediterranean diet was associated to lower risk of mortality in colorectal and prostate cancer survivors. A meta-analysis using a random-effects model showed that higher versus lower diet quality was associated with a 23% reduction in overall mortality in breast cancer survivors. There was evidence that dietary interventions, generally combined with physical activity, improved overall quality of life, though most studies were in breast cancer survivors. Further cohort and intervention studies in other cancers are needed to make more specific recommendations.
Multisource Spatial Data Integration for Use Cases Applications
Authors: Noardo Francesca
Published: December 2021

Big opportunities are given by the reuse and integration of data, which, nowadays, are more and more available, thanks to advances in acquisition and modelling technologies and the open data paradigm. Seamlessly integrating data from heterogenous data sources has been an interest of the geospatial community for long time. However, the higher semantic and geometrical complexity pose new challenges which have never been tackled in a comprehensive methodology. Building on the previous theories and studies, this paper proposes an overarching methodology for multisource spatial data integration. Starting from the definition of the use case-based requirements for the integrated data, it proposes a framework to analyse the involved datasets with respect to integrability and suggests actions to harmonise them towards the destination model. The overall workflow is explained, including the data merging phase and validation. The methodology is tested and exemplified on a case study. Considering the specific data sets’ features and parameters, this approach will allow the development of consistent, well documented and inclusive data integration workflows, for the sake of use cases processes automation and the production of Interoperable and Reusable data.
Attaching onto or Inserting into an Intramolecular Hydrogen Bond: Exploring and Controlling a Chirality-Dependent Dilemma for Alcohols
Authors: Lange Manuel , Sennert Elisabeth , Suhm Martin A.
Published: December 2021

Prereactive complexes in noncovalent organocatalysis are sensitive to the relative chirality of the binding partners and to hydrogen bond isomerism. Both effects are present when a transiently chiral alcohol docks on a chiral α-hydroxy ester, turning such 1:1 complexes into elementary, non-reactive model systems for chirality induction in the gas phase. With the help of linear infrared and Raman spectroscopy in supersonic jet expansions, conformational preferences are investigated for benzyl alcohol in combination with methyl lactate, also exploring p-chlorination of the alcohol and the achiral homolog methyl glycolate to identify potential London dispersion and chirality effects on the energy sequence. Three of the four combinations prefer barrierless complexation via the hydroxy group of the ester (association). In contrast, the lightest complex shows predominantly insertion into the intramolecular hydrogen bond, like the analogous lactate and glycolate complexes of methanol. The experimental findings are rationalized with computations and a uniform helicality induction in the alcohol by the lactate is predicted, independent on insertion into or association with the internal lactate hydrogen bond. p-Chlorination of benzyl alcohol has a stabilizing effect on association, because the insertion motif prevents a close contact between the chlorine and the hydroxy ester. After simple anharmonicity and substitution corrections, the B3LYP-D3 approach offers a fairly systematic description of the known spectroscopic data on alcohol complexes with α-hydroxy esters.

Published: December 2021

Hydrogel antibacterial agent is an ideal antibacterial material because of it could diffuses antibacterial molecules into the decayed area by providing a suitable microenvironment and the hydrogel acts as a protective barrier on the decay interface. The biocompatibility and biodegradation make the removal process easily which were widely used in medical fields. However, there have been few reports on its application for controlling postharvest diseases in fruit. In this study, the Chitosan-Ag (CS-Ag) complex hydrogels were prepared using the physical crosslinking method, which used for controlling postharvest diseases in grape. The prepared hydrogels were stable for a long period at room temperature. The structure and surface morphology of CS-Ag composite hydrogels were characterized by UV-Vis, FTIR, SEM, and XRD. The inhibitory effects of CS-Ag hydrogel on disease in grape caused by P. expansum, A. niger and B. cinerea were investigated both in vivo and in vitro. The remarkable antibacterial activity of CS-Ag hydrogels was mainly due to the synergistic antibacterial and antioxidant effects of CS and Ag. Preservation test showed that the CS-Ag hydrogel had positive fresh-keeping effect. This revealed CS-Ag hydrogels plays a critical role in controlling fungal disease in grape.
Bounds for the Minimum Distance and Covering Radius of Orthogonal Arrays via Their Distance Distributions
Authors: Boumova Silvia , Boyvalenkov Peter , Stoyanova Maya
Published: December 2021

We propose two methods for obtaining estimations on the minimum distance and covering radius of orthogonal arrays. Both methods are based on knowledge about the (feasible) sets of distance distributions of orthogonal arrays with given length, cardinality, factors and strength. New bounds are presented either in analytic form and as products of an ongoing project for computation and investigation of the possible distance distributions of orthogonal arrays with parameters in doable ranges.

The main objective of this study is to apply structural equation modeling with partial least squares and based on covariance to assess the satisfaction of residential electricity consumers. The methodology used compares the results of both structural equation models to indicate the model that best fits the problem of measuring the satisfaction of residential consumers of electricity concessionaires and licensees. The sample used in the survey contained questionnaire responses from 86.175 individuals considering the period from 2014 to 2018. The constructs evaluated were satisfaction, quality, value, loyalty, and trust. Confidence interval analysis shows that all weights are significant, demonstrating the importance of all the indicators that represent the constructs. The trust, quality, and value constructs can explain 74.4% of the variability of the satisfaction construct, so the explanatory capacity of this relationship is considered substantial. Finally, the evaluation of the performance of the service provided by the electric energy concessionaires/licensees, measured by customer satisfaction, allows for the continuous improvement of services and meeting, even if minimally, the expectations of its consumers.
D3 Dihedral Logistic Map of Fractional Order
Authors: Danca Marius-F. , Kuznetsov Nikolay
Published: December 2021

In this paper the D 3 dihedral logistic map of fractional order is introduced. The map 1 presents a dihedral symmetry D 3 . It is numerically shown that the construction and interpretation 2 of the bifurcation diagram versus the fractional order require special attention. The system stability 3 is determined and the problem of hidden attractors is analyzed. Also, analytical and numerical 4 results show that the chaotic attractor of integer order, with D 3 symmetries, looses its symmetry 5 in the fractional-order variant.
Strongly Recurrent Transformation Groups

Published: December 2021

We define the notions of strong and strict recurrency for actions of countable ordered groups on $\sigma$-finite non atomic measure spaces with quasi-invariant measures. We show that strong recurrency is equivalent to non existence of weakly wandering sets of positive measure. We also show that for certain p.m.p ergodic actions the system is not strictly recurrent, which shows that strong and strict recurrency are not equivalent.
Nematode-Microbe Complexes in Soils Replanted with Apple

Apple replant disease is a severe problem in orchards and tree nurseries. Evidence for the involvement of a nematode-microbe disease complex was reported. To search for this complex, plots with a history of apple replanting, and control plots cultivated for the first time with apple were sampled in two fields in two years. Shoot weight drastically decreased with each replanting. Nematodes were extracted from soil samples by floatation-centrifugation, washed on a 20 µm-sieve, and used for DNA extraction. Nematode communities and co-extracted fungi and bacteria were analyzed by high-throughput sequencing of amplified ribosomal fragments. The nematode community and co-extracted fungal and bacterial communities significantly differed between replanted and control plots. Free-living nematodes of the genera Aphelenchus, Cephalenchus, and an unidentified Dorylaimida were associated with replanted plots, as indicated by linear discriminant analysis effect size. Among the co-extracted fungi and bacteria, Mortierella was most indicative of replanting. Some genera, mostly Rhabditis, indicated healthy control plots. Isolating and investigating the putative disease complexes will help to understand and alleviate stress-induced root damage of apple in replanted soil.

Ambulatory cancer centers face fluctuating patient demand and deploy specialized personnel who have variable availability. This undermines operational stability through misalignment of re-sources to patient needs, resulting in overscheduled clinics, high rebooking rates, budget deficits, and wait times exceeding provincial targets. We describe how deploying a Learning Health System framework led to operational improvements within the entire ambulatory center. Known methods of value stream mapping, operations research and statistical process control were applied to achieve organizational high performance that is data-informed, agile and adaptive. Caseload management by disease site emerged as an essential construct that incorporates disease site teams into adaptive, reliable care units, clinically and operationally. This supported clus-tering interdisciplinary teams around groups of patients with similar attributes, while allowing for quarterly recalibration. Systematic efforts were made in the negotiation required to im-plement changes that impacted physicians, nurses, clerks, and administrators. Feedback mecha-nisms were created with learnings curated and disseminated by a core team. The change aligned financial expenditures to the regional demand for specialized services and smoothed clinical operations across 5 weekdays and 2 centers. The impact was predictable, optimized expenditures, increased efficiencies across human and physical resource deployment and improved disease site collaboration in patient care.

The use of agricultural equipment and machinery is one way to increase the productivity and efficiency of farming. In order to accelerate the adoption of agricultural equipment and machinery as part of the application of agricultural mechanization, one of which is through the agricultural equipment and machinery service business/usaha pelayanan jasa alat dan mesin pertanian (UPJA). This study aims to analyze the application of agricultural mechanization, especially related to the use of equipment and machinery by UPJA for the rice production system in Banyumas, Purbalingga and Banjarnegara Regencies. Data were obtained, including the ownership of the equipment and machinery, the extent of coverage carried out by the UPJA, the cost of renting the equipment and machinery determined by each UPJA, and the costs incurred for the operation of the equipment and machinery in each UPJA. The results of the calculation of the working capacity of the hand tractor obtained an average of 0.07 ha hour-1. The lack of ability of equipment and machinery operators as well as the topography of the area and soil conditions are factors that affect the working capacity of the hand tractor in this study. UPJA which has a coverage area of more than the Break Event Point (BEP) value means that the UPJA has met the minimum area that must be processed to break even. The results of the calculation of the B/C ratio are that 9 UPJAs are feasible because the B/C ratio > 1 and 10 UPJAs are not feasible because of the B/C ratio < 1. UPJA whose business is not feasible is expected to improve the managerial and performance of UPJA.
