Efficacy of In-office Bleaching on Microhardness of Permanent Teeth with Antioxidant Re-hardening
Authors: Çakir Esra G , Özcan Suat , Tulunoglu Ibrahim , Üçtaşli Mine B. , Tulunoglu Ozlem
Published: January 2020

Background:

Bleaching procedures affect surface enamel structure and decrease its bonding ability to resin composite restorative materials. The application of re-hardening materials to bleached enamel surfaces may prevent this decrease in micro-hardness.

Objective:

This in-vitro study aims to evaluate the surface micro hardness of human teeth enamel subjected to bleaching with Zoom Advanced Power 2 AP (Phillips, USA), and Opalescence Boost (Ultradent, USA) and compare the re-hardening effects of 10% Sodium Ascorbate, 2% acidulated phosphate fluoride gel, and a 5% Potassium nitrate 0.22% Sodium Fluoride + Calcium Nitrate gel.

Methods:

Ninety human third molar teeth were used. The specimens were randomly assigned to 5 groups. After the bleaching procedure, the specimens were treated with APF, Sodium Ascorbate or Relief gel as re-hardening agents with 30 teeth in each group. Enamel micro-hardness was measured with Vickers Micro-hardness Tester. The data were evaluated with Kolmogorov-Simirnov, one-way ANOVA, Dunnett’s test, post-hoc Tukey and T-tests.

Results:

Statistical analysis revealed no significant differences among initial enamel groups’ micro-hardness values (P>.05); however, significant differences occurred between initial and after bleaching treatment group value for G3 (P< .05). After re-hardening, only the Sodium Ascorbate group showed a statistically significant increase with hardness values (P< .05) for G4 and G5.

Conclusion:

Bleaching treatment conducted with light had no adverse effect on enamel micro-hardness. Sodium Ascorbate can be useful after bleaching to change the adverse effects of bonding on the enamel.

Internationalization through the Lens: Nineteenth- and Twentieth-Century Art Periodicals and Decentred Circulation/L'internationalisation à travers la lentille: revues d'art et circulation décentrée aux 19e et 20e siècles
Authors: Joyeux-Prunel Béatrice
Published: January 2020

Periodicals are an exceptional source for the study of artistic and cultural internationalization. Their content, traditional for occasional research, allows us to reconstruct the chronicle of events and artistic debates of an era, a milieu or a metropolis. However, periodicals are also available as commensurable sources, at an international scale and in the long term. As such, art magazines in particular offer a global perspective on artistic internationalization in the contemporary era. This article proposes a new reading of the history of the internationalization of modern art and the avant-garde through the prism of art periodicals, from the 1860s to the end of the 1960s. We combine three interrelated and complementary levels: the microhistory of transfers between journals, the median approach of social history, and the distant point of view of cartographic study and network analysis. The result is a dynamic and decentralized idea of world geopolitics for the arts, far from the canonical narrative that turns certain centres into the dominant producers of innovation, where peripheries are supposed to remain mere imitators.

Les périodiques sont une source exceptionnelle pour l’étude de l’internationalisation artistique et culturelle. Leur contenu, traditionnellement utilisé pour des recherches ponctuelles, permet de reconstituer la chronique des événements et des débats artistiques d’une époque, d’un milieu ou d’une métropole. Cependant les périodiques constituent aussi des sources commensurables, à l’échelle internationale et sur la longue période. À ce titre, les revues d’art en particulier offrent une perspective globale sur l’internationalisation artistique à l’ère contemporaine. Cet article propose de relire l’histoire de l’internationalisation de l’art moderne et de l’avant-garde au prisme des périodiques d’art, des années 1860 à la fin des années 1960. Trois échelles complémentaires sont articulées: la micro-histoire des transferts entre revues, l’approche médiane de l’histoire sociale, et le point de vue lointain de l’étude cartographique et de l’analyse des réseaux. Il en résulte une idée dynamique et décentrée de la géopolitique mondiale des arts, loin du récit canonique qui fait de certains centres les producteurs dominants de l’innovation tandis que les périphéries n’auraient été qu’imitatrices.
Periodicals In-Between
Authors: Stead Evanghelia
Published: January 2020

This special issue originates from the seventh annual conference of the European Society for Periodical Research (ESPRit) I was entrusted with hosting in Paris on ‘Periodicals In-Between: Periodicals in the Ecology of Print and Visual Cultures’. The event took place between the Bibliothèque nationale de France, Inalco and Paris-Sorbonne University in June 2018. A bilingual venue, it brought together young and advanced scholars and discussed the complex parts played by periodicals in a rich array of cultural and scientific settings and milieus from numerous points of view: history of literature, art history, press and media, visual studies, comparative literature, theatre studies, scientific cultures, translation and reception studies. A variety of serial publications were considered: reviews, magazines, parts, supplements, pull-outs, journals, annuals, anthologies, book series, newspapers, even a radio broadcast. This special issue proposes a few select contributions developed into research articles. By presenting them and recalling the conference’s main arguments and themes, the introduction offers an overview of investigations, and highlights some of the hypotheses significant for periodical studies today.
Comparing Methods for Record Linkage for Public Health Action: Matching Algorithm Validation Study
Authors: Avoundjian Tigran , Dombrowski Julia C , Golden Matthew R , Hughes James P , Guthrie Brandon L , Baseman Janet , Sadinle Mauricio
Published: January 2020

Background

Many public health departments use record linkage between surveillance data and external data sources to inform public health interventions. However, little guidance is available to inform these activities, and many health departments rely on deterministic algorithms that may miss many true matches. In the context of public health action, these missed matches lead to missed opportunities to deliver interventions and may exacerbate existing health inequities.

Objective

This study aimed to compare the performance of record linkage algorithms commonly used in public health practice.

Methods

We compared five deterministic (exact, Stenger, Ocampo 1, Ocampo 2, and Bosh) and two probabilistic record linkage algorithms (fastLink and beta record linkage [BRL]) using simulations and a real-world scenario. We simulated pairs of datasets with varying numbers of errors per record and the number of matching records between the two datasets (ie, overlap). We matched the datasets using each algorithm and calculated their recall (ie, sensitivity, the proportion of true matches identified by the algorithm) and precision (ie, positive predictive value, the proportion of matches identified by the algorithm that were true matches). We estimated the average computation time by performing a match with each algorithm 20 times while varying the size of the datasets being matched. In a real-world scenario, HIV and sexually transmitted disease surveillance data from King County, Washington, were matched to identify people living with HIV who had a syphilis diagnosis in 2017. We calculated the recall and precision of each algorithm compared with a composite standard based on the agreement in matching decisions across all the algorithms and manual review.

Results

In simulations, BRL and fastLink maintained a high recall at nearly all data quality levels, while being comparable with deterministic algorithms in terms of precision. Deterministic algorithms typically failed to identify matches in scenarios with low data quality. All the deterministic algorithms had a shorter average computation time than the probabilistic algorithms. BRL had the slowest overall computation time (14 min when both datasets contained 2000 records). In the real-world scenario, BRL had the lowest trade-off between recall (309/309, 100.0%) and precision (309/312, 99.0%).

Conclusions

Probabilistic record linkage algorithms maximize the number of true matches identified, reducing gaps in the coverage of interventions and maximizing the reach of public health action.

Published: January 2020

Background

eConsulta is a tele-consultation service involving doctors and patients, and is part of Catalonia's public health information technology system. The service has been in operation since the end of 2015 as an adjunct to face-to-face consultations. A key factor in understanding the barriers and facilitators to the acceptance of the tool is understanding the sociodemographic characteristics of general practitioners who determine its use.

Objective

This study aimed to analyze the sociodemographic factors that affect the likelihood of doctors using eConsulta.

Methods

A retrospective cross-sectional analysis of administrative data was used to perform a multivariate logistic regression analysis on the use of eConsulta in relation to sociodemographic variables.

Results

The model shows that the doctors who use eConsulta are 45-54 years of age, score higher than the 80th percentile on the quality of care index, have a high degree of accessibility, are involved in teaching, and work on a health team in a high socioeconomic urban setting.

Conclusions

The results suggest that certain sociodemographic characteristics associated with general practitioners determine whether they use eConsulta. These results must be taken into account if its deployment is to be encouraged in the context of a public health system.
La política deportiva y el valor público del deporte
Authors: Cuevas Galicia Irvin
Published: January 2020

El gobierno y la Administración Pública están en un constante proceso de cambio causado por las nuevas y complejas necesidades que surgen conforme va cambiando la sociedad. El incremento de la percepción negativa que se tiene contra lo público o gubernamental aumenta ante la aparición de problemáticas y fenómenos cada vez más complejos. Es así que se reclaman nuevos modelos y soluciones ante los problemas públicos, donde el deporte tiene que ser considerado un agente de transformación social construido a partir de la idea del bien común y la multidisciplinariedad. La creciente vinculación del deporte con las políticas de salud, de educación o de seguridad pública convierte al deporte y la cultura física en elementos obligados a estudiar y aplicar desde la Admnistración Pública. Consolidar una Política Deportiva sería el salto que impulse la integración de una cultura física sólida, la cual oriente su utilización de recursos públicos no como un gasto obligatorio más, sino como una inversión segura y necesaria que promueve los valores y beneficios propios de la práctica del deporte en toda sus modalidades.

Published: January 2020

A novel, safe and sensitive method of Spectrophotometric estimation in UV - region has been developed for the assay of Fimasartan in its tablet formulation. The present study was undertaken to develop and validate a simple, accurate, precise, reproducible and cost effective UV spectrophotometric method for the estimation of Fimasartan bulk and pharmaceutical formulation. The method have been developed and validated for the assay of Fimasartan using Methanol as diluent. Absorption maximum (λmax) of the drug was found to be 240nm. The quantitative determination of the drug was carried out at 240nm. The method was shown linear in the mentioned concentrations having correlation coefficient R2 of 0.999. The recovery values for Fimasartan ranged from 98.74% to 99.23%.The Percent Relative Standard Deviation of interday and intraday was 0.85% and 0.75% respectively. All the parameters of the analysis were chosen according to the International Conference on Harmonisation guideline and validated statistically using Relative Standard Deviation and Percent Relative Standard Deviation. Hence, proposed method was precise, accurate and cost effective. This method could be applicable for quantitative determination of the bulk drug as well as dosage formulation.

 

KEY WORDS:
Hypergraph framework for irreducible noncontextuality inequalities from logical proofs of the Kochen-Specker theorem
Authors: Kunjwal Ravi
Published: January 2020

Kochen-Specker (KS) theorem reveals the inconsistency between quantum theory and any putative underlying model of it satisfying the constraint of KS-noncontextuality. A logical proof of the KS theorem is one that relies only on the compatibility relations amongst a set of projectors (a KS set) to witness this inconsistency. These compatibility relations can be represented by a hypergraph, referred to as a contextuality scenario. Here we consider contextuality scenarios that we term KS-uncolourable, e.g., those which appear in logical proofs of the KS theorem. We introduce a hypergraph framework to obtain noise-robust witnesses of contextuality from such scenarios.
Our approach builds on the results of R. Kunjwal and R. W. Spekkens, Phys. Rev. Lett. 115, 110403 (2015), by providing new insights into the relationship between the structure of a contextuality scenario and the associated noise-robust noncontextuality inequalities that witness contextuality. The present work also forms a necessary counterpart to the framework presented in R. Kunjwal, Quantum 3, 184 (2019), which only applies to KS-colourable contextuality scenarios, i.e., those which do not admit logical proofs of the KS theorem but do admit statistical proofs.
We rely on a single hypergraph invariant, defined in R. Kunjwal, Quantum 3, 184 (2019), that appears in our contextuality witnesses, namely, the weighted max-predictability. The present work can also be viewed as a study of this invariant. Significantly, unlike the case of R. Kunjwal, Quantum 3, 184 (2019), none of the graph invariants from the graph-theoretic framework for KS-contextuality due to Cabello, Severini, and Winter (the ``CSW framework", Phys. Rev. Lett. 112, 040401 (2014)) are relevant for our noise-robust noncontextuality inequalities.

In this study, the reduced graphene oxide (rGO) synthesized by using lime juice as an environmentally friendly reducing agent and inexpensive cost. The synthesis was carried out by oxidizing graphite with the Hummer method to form graphene oxide (GO) was formed, then the GO was reduced by using lime as the natural reducing agent. X-ray analysis shown a vital diffraction pattern for graphite at 2θ = 26.4°, for graphene oxide appears around 2θ = 10° and 43o, and rGO at 2θ = 23.8°. Furthermore, the infrared spectrum of the three samples showed the peak of the hydroxyl group at 3412 cm-1, which appeared on graphene oxide, but was not observed in rGO. The vibrational mode of carbonyl (C=O) at 1723 cm-1 was also observed with high intensity on graphene oxide. This information showed that GO has a large number of oxygen-containing groups. Then, in the dissolution test shown that the GO was more soluble in polar solvents such as water than ethanol.

Authors: Hasby Hasby , Nurhafidhah Nurhafidhah , Akbar Said Ali
Published: January 2020

The anthocyanin activity of Gayo Arabica coffee husk in variations in acid solution, temperature, and pH has been assessed through UV-Vis studies. It is important to optimize these factors to increase the long-term stability of anthocyanins for use in various fields. Gayo Arabica coffee husks was extracted through maceration method with methanol. This process obtained a coffee husks extract of 1.176 mg/μL. The UV-Vis spectrum of the extract displayed the major absorption peak at λmax= 529 nm in hydrochloric acid (HCl), this assigned by the electronic transition from flavylium as the particular characteristic of anthocyanin compounds. The anthocyanin from the extract was stable at temperatures of 35oC and 50oC, to have a major absorption peak at λmax= 529 nm. Therefore, it could probably be said that the lower the temperature, the higher the absorbance value of anthocyanin. Then, husks extract was getting red at pH 1 and 3; almost colorless at pH 5, 8 and 10; and yellow at pH 12. The more acidic conditions causes more anthocyanin pigments to be observed in the form of flavylium or oxonium cations color. Finally, Gayo Arabica coffee husks extract can absorb both ultraviolet (UV) and visible light (visible).

Residency Scholarship Within Practice-based Research Networks
Authors: Weidner Amanda , Gilles Ryan , Seehusen Dean A.
Published: January 2020

Background and Objectives: Finding scholarship opportunities is a common struggle for family medicine residency programs, especially community-based programs. Participation in practice-based research networks (PBRNs) has been suggested as one option, but little is known about resident engagement in PBRNs. This study explores how PBRNs are currently involving family medicine residency programs and whether there are additional opportunities for engagement.
Methods: We conducted a cross-sectional survey of 126 primary care PBRN directors regarding residency program involvement in PBRN governance and scholarly activity. We used descriptive statistics to characterize our sample and bivariate analyses to assess association between involvement of residency programs in PBRNs and PBRN characteristics.
Results: Most responding PBRNs (N=56, 44.4% response rate) included at least one residency program (80%) and many had residency faculty involved in projects (67.3%), though involvement of residents was less common (52.7%). When involved, residents were part of fewer projects but participated in the full range of research activities. Few PBRNs had deeper engagement with residencies such as written goals specifying their inclusion in projects (23.6%) or residency faculty participation in the PBRN’s governing body (45.5%). Most PBRNs not currently involving residents are interested in doing so (73.9%), and half of these have the resources to do this.
Conclusions: Most family medicine and primary care PBRNs have some involvement with residency programs, usually at the faculty level. Building on current PBRN involvement and making connections between local PBRNs and residency programs where none exist represents an excellent opportunity for education and for growing the research capacity of the discipline.

Introducción: este artículo pretende desentrañar el sentido sobre asuntos humanos en la escuela. Objetivo: busca comprender el significado de los imaginarios colectivos frente al ideal de sujeto que se constituye dada su formación política, ética y ciudadana a propósito de la convivencia y la paz en las cuatro instituciones Lasallistas del Área Metropolitana del Valle del Aburrá y Medellín. Materiales y métodos: la metodología es hermenéutica, además de la antropología de la educación. La información utilizada parte de la fase de diagnóstico del proyecto. Su recolección se hizo a partir de grupos focales con quienes se trabajaron cartografías sociales con estudiantes, padres de familia, docentes y directivos, además de entrevistas no estructuradas a exalumnos. Resultados: el proceso evidenció prácticas pedagógicas intencionadas desde los propósitos de formación del Distrito Lasallista Norandino (DLN), y el Proyecto Educativo Lasallista y su propuesta formativa para el buen vivir. Conclusiones: es claro que a pesar de las pautas que intentan favorecer las relaciones de paz y convivencia, esta intención entra en tensión porque aparecen situaciones que generan imposiciones y desaparece el respeto entre las personas, hay también manifestaciones de reconocimiento y solidaridad para con los otros, pero especialmente en el terreno de las diferencias económicas. En cuanto a la convivencia, hay problemas de imposición y relaciones verticales de poder sin posibilidades dialógicas entre los actores. La imposición de la norma no permite reflexión, y genera emociones que se distancian de una convivencia y de una construcción pacífica y autónoma.

Authors: Cortés Prieto Eduardo , Osorio Álvaro Acevedo
Published: January 2020

Introducción. Una cuarta parte de los suelos agrícolas del mundo padece algún grado de deterioro, especialmente por factores antrópicos, no obstante, reducir el daño es posible cuando se desarrollan prácticas adecuadas de producción. Objetivo. Evaluar la efectividad de prácticas agroecológicas de conservación de suelos de ladera en el municipio de Guasca – Cundinamarca. Materiales y métodos. Se establecieron cuatro tratamientos: barreras vivas, barreras muertas, zanjas de infiltración, terrazas y un testigo, por cada tratamiento se realizaron 4 repeticiones, para un total de 20 unidades experimentales (UE). Se establecieron cultivos asociados de arveja (Pisum sativum), fríjol (Phaseolus vulgaris) y zanahoria (Daucus carota), en surcos en contrapendiente, obteniendo 6 surcos por UE. En cada UE se instaló una zanja recubierta con polietileno, con el objetivo de conducir el volumen de agua escurrido y los sólidos arrastrados al recipiente colector final. Del volumen obtenido, después de una respectiva homogenización con un agitador manual, se obtuvieron muestras de 200 ml para posteriormente secarlas y pesarlas en laboratorio. Resultados. Las pérdidas de suelo y agua por escorrentía presentaron un comportamiento variable, lo que puede ser atribuido a la interacción entre la intensidad y frecuencia de las precipitaciones, textura de suelo, manejo histórico del suelo y la variedad de prácticas de conservación empleadas. Conclusión. Todas las prácticas de conservación de suelos implementadas contribuyeron a reducir la pérdida de sedimentos, siendo las zanjas de infiltración la mejor práctica de conservación, presentando una reducción del 87,8 % de las pérdidas frente al testigo.

On the prosodic traits of the declension of nouns in the Ijekavian West-Serbian speeches
Authors: Markovic Slavoljub
Published: January 2020

The paper systematically and analytically delves into conspicuous accent
characteristics of the declension of nouns in the Ijekavian West-Serbian
speeches (less commonly of lexical categories and individual examples). The
demonstrated instances (mainly of prosodic declensional relations) are
examined from multiple perspectives: lexical productivity of accent types,
areal and/or systemic limitations, the level of accordance with exemplary
(Vuk?s or Danicic?s) accent patterns, the nature of the correlations with
appropriate circumstances in kindred speeches. On the basis of the chosen
corpus and analytical viewpoints, we have confirmed the following: the
special status and inherent incompatibility of West-Serbian Ijekavian
complex somewhat modifi es classic prosodic models. Some of Danicic?s
alterations are missing (e.g. svekar-svekra type), some are areally limited
(e.g. starac-starca type), some are lexically reduced (e.g. rod-roda type).
Nevertheless, the observed differences are dialectally inevitable and
therefore cannot be said to undermine the organic unity of the West-Serbian
Ijekavian complex with the other segments of the vast and extensive
East-Herzegovinian dialect.
Effects of Stirring Duration and Casting Temperature in Ultrasonic Assisted Stir Casting of Al A356 Matrix Composites
Authors: YÜKSEL Tuğçe Büşra , AYBARÇ Uğur , ERTUĞRUL Onur
Published: January 2020

In the present study, two main
parameters as stirring duration and casting temperature were taken into
consideration in order to determine the effect of stirring process on
mechanical properties of aluminum matrix composites. AlSi7Mg0.3 aluminum alloy
and silicon carbide (SiC) particles were used as matrix and reinforcement
materials to produce composite samples. Firstly, stirring processes were
applied as the combination of mechanical stirring and ultrasonic vibration for
the various time as 3-1, 2-2 and 1-3 minutes, respectively. To determine the
effect of stirring process, tensile tests were applied to whole samples and
Quality Indexes (QI) were calculated by using the results of tensile tests.
According to the values of QI, the produced samples with the combination of 1
minute mechanical stirring and 3 minutes ultrasonic vibration showed the
maximum mechanical properties. Afterwards, the determined stirring combination
was chosen to specify the appropriate molten metal temperature. Three different
casting temperatures were addressed as 700˚C, 720˚C and 740˚C. According to
mechanical tests results and calculations of QI and metallographic analysis,
the maximum mechanical properties were obtained with aluminum composite
reinforced with 1 wt. % SiC at 720˚C molten metal temperature by applying 1
minute mechanical stirring and 3 minutes ultrasonic vibration.
Introduksjon: Menneskeverd – mangfoldige forståelser for en mangfoldig skole
Authors: Valen-Sendstad Ådne , Christensen Ingrid Reite
Published: January 2020

This chapter is called “Human dignity – diverse approaches for diversity in school”. Human dignity is one of the most important value concepts, as it appears as a common, global value that “everyone” owns – and is yet the source of the most merciless ongoing debates in society. In school, these debates are less in focus. In the formal curriculum and in the educational laws, dignity appears as a repeated basis. Yet, in educational discourse and teaching practices the definitions are vague and seldom concretized. In this chapter, we ask the following: 1) What characterizes different approaches to dignity as a concept? 2) What challenges and possibilities do the different approaches to dignity entail in school?
In this chapter we will therefore aim at presenting different approaches to dignity. We do so by presenting a broad spectrum of approaches to dignity. We argue that dignity might be a diverse concept, and it can be explored as approaches promoting the “dignity of the strong” versus the “dignity of the weak”. The different approaches are exemplified with key issues of diversity and inclusion in school. The aim of the chapter is to give an introduction and an overview of diverse approaches to dignity – and thus, finding the beginnings of new debates about dignity for a diverse school.

Published: January 2020

This article explored the differences between Ahmad Hassan and Siradjuddin Abbas understanding on reward prize hadith, the methods used and the factors influencing differences. As a cadre of the two competing groups, these two scholars formulated an understanding of the reward of hadith to legitimize the understanding of each group.The results of the study found that Ahmad Hassan viewed that reward prize hadith contrary to al-Qur’an and rejected all methods of resolution. So this hadithwas a da’if quality and Mardud status. Besides, Siradjuddin Abbas looked at the reward prize hadith wasṣaḥiḥ quality and maqbūl status using a correlative approach. Understanding rewards prize hadith by Ahmad Hassan and Siradjuddin Abbas disputed of religious understanding between the Young People and the Old People and influenced the socio-cultural context of the mid-XX century
Environmental Interpretation: Hermeneutic Analysis Of The Interpretation Of Anthropocentric Verses In Al-Qur'an
Authors: Fatah Abdul , Taufiq Imam
Published: January 2020

The aim of this study is addressed to environmental problems from the perspective of the Qur'an. The focus of the research is the anthropocentric verses in the Qur'an. Anthropocentric verses are verses that have the meaning of humans as the center of the universe or humans as creatures that are super-being. The categorization of anthropocentric verses is compiled thematically (maudhû’î) using a contextual hermeneutic approach. The classification of anthropocentric verses as a result of this research are: 1) Humans as the most glorified creatures 2) Humans as creatures that have power in nature, and 3) Humans as caliphs on earth. Several hermeneutical analyzes of the anthropocentric verse have been obtained. Human must not be arrogant as creatures that degrees are glorified. Humans are instructed not to cause damage on the earth and must be able to do good ihsân to all creatures created by Allah SWT. The obligation of humans as caliphs on earth is to prosper the earth rather than damage the earth
The Use Of Hermeneutics Double Movement Fazlur Rahman In Comprehending Hadith Of The Unsuccessful Leadership Of Women
Authors: Ainurrofiq Faiq
Published: January 2020

This study examines the hadith about the failure of a nation when led by women. Textually, the meaning of the hadith is contrary to social reality that exhibits the number of women to become leaders in the political sphere. Using the contextual approach of double movement hermeneutics, Fazlur Rahman, this study compares textualist and contextualist methods in interpreting the hadith based on the meaning of the text and the historical, social and political context that underlie the emergence of the hadith. Based on the results of the study, it was found that the cause of a person's inability to be a leader was not because of his gender but because of lacking the capacity to be a leader. It can be found leaders who fail because they do not have leadership capacity, only with popularity, money, and political dynasties, and less capable in leadership. Lastly, this type of leader is addressed by the hadith, not the focus on gender

Potentials of crops residues – A case study for the province Vojvodina
Authors: Martinov Milan , Djatkov Djordje , Viskovic Miodrag
Published: January 2020

Crop residues are targeted as energy sources and feedstock for diverse products. A six-year lasting investigation, aiming to determine the yield potentials of crop residues of mostly grown field crops wheat, soybean and corn in the province Vojvodina (Serbia), was performed. The three levels of potentials were distinguished: theoretical, technical and sustainable. Two seasonal weather conditions were distinguished – common and dry, and their impact on the biomass yield was analyzed. The yields were expressed as absolute and relative to grain yield since the grain yield is always measured, and is available in national statistics. During common seasons, technical potentials were about 56% for wheat, 45% for soybean and 41 or 51% for the two considered corn stover collection procedures. For dry seasons, the technical potential of all considered crops was reduced to between 30 and 50%. On field remained aboveground residual biomass and its relative (to grain) amount, which was between 43 and 60%, was defined. It was concluded that the defining of sustainable potentials is a very complex task. Besides the aforementioned, measures aimed to preserve soil fertility, some overlooked issues in the literature and practice were listed and commented on.

An electrical measurement is non-linear when it is affected by the applied stimulus, i.e. when the measured phenomenon changes with amplitude. If pinched hysteresis loops can be observed in the voltage current representation, the underlying tissue can be classified as a memristor. Several biological memristors have been published, like human skin and apples. However, changes in the polarization impedance of electrodes may also cause pinched hysteresis loops. The question whether the reported biological memristors are real or whether the results just reflect changes in the polarization impedance arises. If the impedance of the measured object is close to or smaller than the polarization impedance of the used electrodes, the latter may dominate the measurement.

In this study, we investigated the non-linear electrical properties of silver/silver chloride electrodes in a sodium chloride solution that has a similar concentration as human sweat and compared these to results from human skin. First of all, we found that silver/silver chloride electrodes in sodium chloride solution can be classified as memristors. However, the currents obtained from the sodium chloride solution are much higher than the currents recorded from human skin and there is a qualitative difference in the pinched hysteresis loops in both cases. We can conclude that the non-linear electrical measurements with silver/silver chloride on human skin are actually dominated by the skin and we can confirm that the human skin memristor really exists.

Sixteen volunteers each drank 700 ml sugar-containing soft drink during two successive periods and the blood sugar was measured at 10 min intervals together with electrical impedance spectroscopy and near infrared spectroscopy (NIR). A maximum correlation of 0.46 was found for the electrical measurements but no clear separation between low and high blood glucose levels were found in the NIR measurements. The latter was attributed to the experimental design where the NIR probe was removed from the skin between each measurement.

Coastal areas in the Canggu and Seminyak areas located in Badung Regency, Bali Province are very attractive tourism. The development of tourism has an impact on coastal conditions. The coastal conditions analyzed are changes in coastline that occurred during 2015-2019 using remote sensing. The satellite image data used in the analysis is Sentinel 2A image data that can be accessed for free with a spatial resolution of 10 meters. Image data processing is divided into three stages, namely preprocessing, processing, and post processing using Sentinel Application Platform (SNAP) software. The preprocessing stage includes the resampling, masking, and subset areas. The processing stage includes digitizing the coastal area, digitizing accuracy analysis using the Support Vector Machine (SVM) method, and the post processing stage including correction of shoreline changes. Bands in image data used for detection of coastal areas are band 8 (NIR), 8A (narrow NIR), 11 (SWIR), and 12 (SWIR). Based on the results of the analysis of shoreline changes carried out during 2015-2019, it was found that the average shoreline changes were 1.42 m / year with erosion conditions in which the dominant wind direction originated from the southwest towards the northeast coast of the sea of ??Bali. The results of digitizing the coastal area using the Fine Gaussian SVM method with the greatest accuracy value is 87.8%.
