The Phenomenon and the Characteristics of Precariate in Hungary: Labormarket situation, Precariate, Subjective health
Authors: Erdei Renáta J , Fedor Anita R. Fedor R.
Published: November 2019

Anita R. Fedor- Renáta J. Erdei Abstract The focus of our research is labor market integration and the related issues like learning motivation, value choices, health status, family formation and work attitudes. The research took place in  the North Great Plain Region – Szabolcs-Szatmár-Bereg county, Nyíregyháza, Nyíregyháza region, Debrecen, Cigánd district (exception),  we used the Debrecen and the national database of the Graduate Tracking System. Target groups: 18-70 year-old age group, women and women raising young children, 15-29 year-old young age group, high school students (graduate ones) fresh university graduates. The theorethical frameworks of the precariate research is characterized by a multi-disciplinar approach, as this topic has sociological, economic, psychological, pedagogical, legal and health aspects.   Our aim is to show whether There is relevance between the phenomenon of precariate and labor market disadvantage and how individual insecurity factors affect a person’s presence in  the labor market. How the uncertainties in the workplace appear in different regions and social groups by expanding the theoretical framework.According to Standing precariate is typical to low gualified people. But I would like to see if it also typical to highly qualifiled young graduates with favourable conditions.It is possible or worth looking for a way out of the precarious lifestyle (often caused by objective reasons) by combining and using management and education.Are there definite features in the subjective state of health of groups with classic precariate characteristics? Results The research results demonstrate that the precarious characteristics can be extended, they are  multi-dimensional.The personal and regional risk factors of labor market exclusion can develop both in different regions and social groups. Precarized groups cannot be connected exclusively to disadvantaged social groups, my research has shown that precarious characteristics may also appear, and the process of precarization may also start among highly qualified people. Precariate is a kind of subjective and collective crisis. Its depth largely depends on the economic environment, the economic and social policy, and the strategy and cultural conditions of the region. The results show, that the subjective  health of classical precar groups is worse than the others.

The history of medieval learning has traditionally been studied as a vertical transmission of knowledge from a master to one or several disciples. Horizontal Learning in the High Middle Ages: Peer-to-Peer Knowledge Transfer in Religious Communities centres on the ways in which cohabiting peers learned and taught one another in a dialectical process - how they acquired knowledge and skills, but also how they developed concepts, beliefs, and adapted their behaviour to suit the group: everything that could mold a person into an efficient member of the community. This process of 'horizontal learning' emerges as an important aspect of the medieval learning experience. Progressing beyond the view that high medieval religious communities were closed, homogeneous, and fairly stable social groups, the essays in this volume understand communities as the product of a continuous process of education and integration of new members. The authors explore how group members learned from one another, and what this teaches us about learning within the context of a high medieval community.

Published: November 2019

The green mantle of the earth! This metaphor is a poetic image that borrows from the vocabulary of weaving and epitomizes the Renaissance interest in "fashioning green worlds" in art and poetry. Here it serves as a motto for a cultural poetics that made representing living nature increasingly popular across Italy in the Early Modern period. The explosion of landscape art in this era is often associated with the rise of interest in the literary pastoral, narrowly defined, but this volume expands that understanding to show Green’s broad appeal as it intrigued audiences ranging from the ecclesiastic to the medical and scientific to the humanistic and courtly. The essays gathered here explore the expanding technologies and varied cultural dimensions of verzure and verdancy in the Italian Renaissance, and thus the role of visual art in shaping the poetics and expression of greenery in the arts of the 16th-century and beyond.
German Post-Socialist Memory Culture
Authors: Bouma Amieke
Published: November 2019

After German unification, former officers of the GDR state security service united with GDR professors and cultural managers to establish the East German Committee of Associations (OKV). On the basis of encompassing oral history into this complex web of interest organizations and memory clubs, Bouma argues that these activists are driven by an epistemic nostalgia: a longing for the time when their political understanding of the world was seemingly unchallenged. Far from constituting a ‘second life of the Stasi’, the main goal of OKV associations has been to validate the personal biographies of their activists, against the now prevalent view that the GDR was a ‘state of injustice’. While the OKV quickly adapted to the new legal procedures in post-socialist Germany, their staunch defence of the GDR heritage complicates their relation to SED successor party Die Linke and other radical left parties and associations, even when they share practical goals.
Film VerORTen: Film als Forschungs- und Kommunikationsmedium in der Geographie
Authors: Thieme Susan , Eyer Philipp , Vorbrugg Alexander
Published: November 2019

Abstract. In this “positioning” we discuss current developments, possibilities and challenges around working with film in and for geography. We describe possibilities that certain conscious and collaborative ways of employing film offer: They point beyond film analysis and are more than a mere add-on to communicate research results, but rather can stimulate new forms of reflexivity and creativity along different steps of research and teaching processes. We further show how the emergence of new digital and physical platforms can enable and support exchange on film and other digital media, using the example of our new media laboratory (mLab) at the University of Bern.
The phonology and micro-typology of Arabic R
Authors: Youssef Islam
Published: November 2019

The R sound exhibits considerable variability both across and within Arabic dialects; one that covers place and manner of articulation, as well as the notorious emphatic-plain distinction. Some R phones are in contrastive distribution, while others are contextually conditioned or free variants. This article aims to establish the underlying R phonemes in the spoken varieties of Arabic, evidence of which is sought in R’s dialect-specific phonological behavior: in minimal pair contrasts, distributional phenomena, loanword phonology, and phonological processes that target or are triggered by R. Investigation of such evidence reveals four major patterns based on the nature and number of R phonemes, consequently classifying Arabic dialects into four types: the split-R dialects (primarily Maghrebi and Egyptian dialect groups), the emphatic-R dialects (the Levantine group), the plain-R dialects (the Gulf group together with most peripheral dialects), and the uvular-R dialects (the qeltu-dialects of Mesopotamia). The analysis employs a minimalist, contrast-based model of feature geometry to characterize aspects of the attested R’s – such as emphatic-ness, coronality, dorsality, and sonority – and shows that the typology is directly mirrored in the representation. This has theoretical implications as well. Diverse rhotic representations within closely related language varieties demonstrate that distinctive features should not be interpreted as rigidly as is often assumed, and call attention to the semi-arbitrary relationship between phonetics and phonology.
Comparación método Hardy Cross y Sofware Epanet en diseño de redes de agua potable
Authors: Rodríguez Molina Yeraldo Andrés , Loaísiga Henry Eduardo
Published: November 2019

Los problemas de hidráulica de tuberías (por ejemplo, proyectos de sistemas de abastecimiento de agua potable) históricamente se han venido resolviendo por medio del método “empírico” de Hazen Williams debido a su naturaleza explícita. Sin embargo, dicho método tiene restricciones para su aplicabilidad, las que muchas veces no se tienen en cuenta en el proceso de diseño. Razón por la cual es importante retomar la metodología con fundamento en la física clásica como es el caso del método de Darcy – Weisbach que no posee limitación alguna. Con ayuda de las computadoras este método deja de ser tan engorroso como en sus inicios (1936).Para la presente investigación se emplearon los métodos de cálculo de pérdidas de carga por fricción en tuberías de Darcy – Weisbach en conjunto con la ecuación de Colebrook – White utilizando como valor de referencia la ecuación de Swamee – Jain en un proceso de análisis numérico iterativo de punto fijo para calcular el factor de fricción de Darcy en tuberías. Con lo cual fue posible implementar el método de “Hardy Cross con Corrección de Caudales” en la red de distribución y, posteriormente, observar las variaciones con respecto al software EPANET. Se demostró que el uso de ambos métodos genera resultados por debajo de 1% de variabilidad, lo cual, evidencia que ambas metodologías son congruentes. La convergencia presenta una considerable sensibilidad a las variaciones en la precisión decimal.

Published: November 2019

Aim of study: The reproductive performance over a five year period in three different sole broodstocks: wild males with cultured females (WM), cultured males with wild females (CM), and a control of cultured males and females (C).Area of study: Cantabria, Northern Spain.Material and methods: The parental contribution was evaluated through the allocation of hatched larvae and a behavioural study was performed using underwater video recordings.Main results: Fertilized natural spawns were only obtained from group WM showing a significantly higher mean annual volume of floating eggs compared with groups CM and C. Over the entire 5-yr a higher number of spawns, total and floating volumes of eggs were obtained compared with groups CM and C. The analysis of four polymorphic microsatellites enabled the identification of the individuals involved in the fertile spawns by parental assignment. The percentage of individuals contributing to spawns ranged between 56.3% and 75% showing fidelity patterns. However between 46.2% and 68.6% of the contribution to production was a result of the crossing of three single couples. According to the behaviour analysis, group WM presented the highest peak of activity at 20:00 h and a higher activity profile during the night, moreover, the courtship behaviours “swim follow” and “swim followed”, were only recorded in group WM.Research highlights: The study has importance for aquaculture as it demonstrated how broodstocks with wild males and cultured females had adequate egg production for a commercial operation to supply eggs and implement single sex breeding programs.

This study took the student aid data of a normal university in northern Jiangsu Province in 2018 as the object ofstudy, and studied the characteristics of student aid work in local colleges. Through the analysis of the data, it isfound that the characteristics of student aid in local undergraduate colleges and universities in China are as follows:the main source of investment is government, supplemented by colleges, and the amount of social aid is small andunstable; the function of the aid work is still mainly to help the poor, supplemented by awards for the students withexcellent academic performance, and aid for poor students without extra requisites are large in amount. The projectsrewarding outstanding students from the college funds are few in ordinary local colleges and universities, with lowreward amount per capita; the willingness of college students to apply for student loans is low, as loans need to berepaid, the attraction of loans to poor students who can afford partly of the cost is weak, compared with manynon-repayment and non-academic performance requirements aid projects.

Procurar os livros nas prateleiras de uma biblioteca em casa é como começar uma viagem cuja jornada nunca termina, uma aventura que pode ser recriada uma e outra vez em cada turno da página. No entanto, como selecioná-los corretamente? Como adquirir aqueles que são úteis, com materiais adequados e sem opiniões venenosas? Como entre tantas leituras não se escolhem aquelas impossíveis de ler devido ao caráter pequeno da letra ou à excessividade de seu preço? Entre 1910 e 1914, os leitores de periódicos poderia encontrar uma resposta a essas perguntas, porque, anúncios vendendo enciclopédias e compêndios de história do mundo, eles eram como um daqueles lugares onde a construção de novos campos de leitura mais fácil e mercados culturais. Assim, o objetivo desta apresentação é analisar uma selecção de anúncios que estão nas páginas de Caras y Caretas, oferecendo para as coleções de venda de livros para tentar vislumbrar as transformações nos modos de movimento da escrita e as práticas de leitura tentaram resolver um novo problema: o que ler?
Mapeando uma cultura profissional transnacional: as revistas (pan)americanas de arquitetura no Cone-Sul (1920-1940)
Authors: Novo Leonardo Faggion
Published: November 2019

O presente artigo busca indicar como as revistas técnicas de arquitetura e urbanismo de quatro países do Cone-Sul americano (Argentina, Brasil, Chile e Uruguai) possibilitam mapear uma cultura profissional transnacional. A intensa circulação de ideias, projetos, textos e pessoas no entreguerras, sobretudo a partir de 1920, data em que ocorreu o I Congresso Pan-Americano de Arquitetos, nos permite refinar a abstrata noção de “circulação” que se consolidou na historiografia da arquitetura e do urbanismo nas últimas décadas, bem como identificar os limites da categoria de “rede” para se pensar um campo em franca disputa e embate, portanto, dinâmico. Espera-se, com isso, contribuir para uma historiografia que extrapole os limites nacionais e enfatize como esses momentos, espaços ou atitudes de se promover o debate foram constitutivos para a disciplina ao longo do século XX e assinalar a noção de “nebulosas” como alternativa aos limites identificados em relação ao caráter rígido e cartesiano das redes.
Perpetradores no cinema sobre as ditaduras do Cone Sul: do arquétipo ao círculo íntimo
Authors: Seliprandy Fernando
Published: November 2019

Na filmografia que retrata a ditadura brasileira, os personagens de torturadores e colaboradores civis geralmente se enquadram em arquétipos bem definidos de antagonistas e coadjuvantes. O artigo traça uma cartografia desses arquétipos em um corpus de títulos ficcionais e documentais brasileiros realizados desde a Abertura política, identificando as figuras e nuances em jogo: o torturador brucutu; o torturador com laivos de consciência; o empresário patrocinador da repressão; o médico acobertador de violações; o religioso alinhado ao regime. A despeito dos matizes, em todos esses casos as culpas e cumplicidades acabam circunscritas dentro das fórmulas de arquétipos cristalizados, relegadas a um microcosmo de “vilões” distantes do tecido social. Um segundo movimento da análise propõe a comparação entre esse panorama geral e dois documentários específicos: 70 y Pico (Mariano Corbacho, Argentina, 2016) e El pacto de Adriana (Lissette Orozco, Chile, 2017). Ambos são dirigidos por descendentes de indivíduos ligados à estrutura repressiva das ditaduras de seus respectivos países. Na chave do documentário subjetivo que revolve as interfaces entre memória familiar e história, esses filmes jogam luz sobre personagens menos óbvios da órbita da repressão. Pessoas comuns que integram uma zona cinzenta muito próxima, onde se enraíza o apoio social ao autoritarismo.
Os escritos de José Enrique Rodó na Revista Nacional de Literatura y Ciencias Sociales, esboço de uma história literária
Authors: Santos Elisângela da Silva
Published: November 2019

Neste artigo discuto os textos do pensador uruguaio José Enrique Rodó publicados na Revista Nacional de Literatura y Ciencias Sociales (1895-1897), periódico uruguaio finissecular que desempenhou expressão ímpar no processo de sociabilidade intelectual da América Latina. Minha hipótese, é que seus escritos ofereceram ferramentas para a história da literatura produzida pós-emancipação política, num momento marcado pela fragmentação ideológica, em que configurou como grande desafio encontrar uma posição entre a hegemonia da literatura europeia – principalmente a de origem francesa – e a necessidade de elaboração de uma literatura continental autêntica. Nesse sentido, ao mapear as publicações sequenciais de Rodó, é possível percebê-las também como linhas definidoras de um saber sobre a literatura hispano-americana, que forjou um sistema analítico interessado na consolidação de um conhecimento que compreendeu a história intelectual, o pensamento social hispano-americano e a sociedade.

Reviewing the Equilibrium and Causal Relationships between Stock Market Development and Economic Growth in Jordan
Authors: Malkawi Eyad M.
Published: November 2019

The relationship between stock market development and economic growth has been diversely investigated by many researchers. This paper investigates the equilibrium and causal relationships between stock market development and economic growth in Jordan for the 1980-2018 period. It employs the ARDL approach and the results show evidence of a co-integration and causal relationships between variables. These results are broadly consistent with similar studies carried out for other developing economies.
Equity Premium Prediction with Structural Breaks: A Two-Stage Forecast Combination Approach
Authors: Yin Anwen
Published: November 2019

This paper introduces a two-stage out-of-sample predictive model averaging approach to forecasting the U.S. market equity premium. In the first stage, we combine the break and stable specifications for each candidate model utilizing schemes such as Mallows weights to account for the presence of structural breaks. Next, we combine all previously averaged models by equal weights to address the issue of model uncertainty. Our empirical results show that the double-averaged model can deliver superior statistical and economic gains relative to not only the historical average but also the simple forecast combination when forecasting the equity premium. Moreover, our approach provides an explicit theory-based linkage between forecast combination and structural breaks which distinguishes this study from other closely related works.
A LEOPARD OR A PANTHER? The Pairs of the Stag and the Predator in Vittore Carpaccio's Meditation on the Passion
Authors: Moscovich Atara
Published: November 2019

The current paper will suggest an interpretation of two pairs of animals featured in Vittore Carpaccio's Meditation on the Passion, i.e., a stag and a predator of the Felidae family, which in one case devours the stag, and in the other – follows it. The paper will attempt to answer the question why did Carpaccio choose to paint the same motif twice, and why in two differing variations?

The aim of this paper is to contribute to the research of the iconography of Job, and to the research on animal symbolism in art, and particularly the ongoing effort to decipher Carpaccio's Meditation on the Passion. Its specific and unique contribution will be to suggest a new interpretation to the peaceful predator, presented on right-hand side in Carpaccio's Meditation, seeing it in a new light – not as a wild animal tamed by a religious transformation, as suggested in previous literature, but rather as an inherently positive one. This reading will be informed by primary sources, which will be connected here with the stag and their predators in Carpaccio's Meditation for the first time.

How to Improve Local Turnout

Even though many municipalities use a variety of means to improve turnout in local elections, citizen participation in local elections is a point of concern in many Western countries, including the Netherlands. Our research question is therefore: How effective are municipal efforts to improve turnout in (Dutch) local elections? To this end, we collected data from three sources: (1) a survey sent to the municipal clerks of 389 Dutch municipalities to learn what they do to improve turnout; (2) data from Statistics Netherlands on municipalities’ socio-demographic characteristics; and (3) data on the turnout in local elections from the Dutch Electoral Council database. Using hierarchical multiple regression analysis, we found that the direct impact of local governments’ efforts to improve turnout is low. Nevertheless, some measures seem to be able to make a difference. The relative number of polling stations was especially found to impact turnout.

Opening the Opaque Blank Box

In this article, we propose an in-depth exploration of blank and null ballots in the recent 2018 local elections in Wallonia (Belgium). In the official results, both blank and null ballots are merged together and are classified as invalid votes. After obtaining the authorization to access genuine electoral ballots, we study the votes which were not considered for the composition of local councils in detail. The dataset is a representative sample of 13,243 invalidated ballots from 49 Walloon municipalities. We first describe how many of these invalidated ballots are blank and how many are null votes, as well as the nature of the nulled votes (unintended errors or intentionally spoiled ballots). Second, we dig deeper into the differences between ballots that have been intentionally invalidated by voters (blank votes and intentional null votes) and ballots non-intentionally invalidated. Our results show that most of the ballots (two-thirds) are null ballots and that among them, half are unintentional null ballots. Finally, we show that contextual (socio-demographic and political) factors explain the variations in intentional and unintentional null votes across municipalities.

Sub-Constituency Campaigning in PR Systems

Sub-constituency campaigning occurs when parties focus their campaign resources on specific geographical areas within an electoral district. This behaviour was traditionally thought to occur only in single-member plurality elections, but recent research demonstrates that proportional systems with multi-member districts can also elicit sub-constituency campaigning. However, most studies of sub-constituency campaigning rely on self-reported measures of campaigning, not direct measures of campaign intensity in different regions and communities. We present novel data on geographical variations in the intensity of Flemish parties’ campaign advertising during the 2014 general elections in Belgium, which provides a direct measure of sub-constituency campaigning. Our findings show clear evidence of sub-constituency campaigning: parties campaign more intensely in municipalities where they have stronger electoral support and in municipalities with greater population density.

The First Bite Syndrome is a rare late (1-2 months) post operation complication of surgery in the infratemporal fossa, parapharyngeal space and especially involving the deep lobe of parotid gland. Sometimes it can significantly worsen the patient's quality of life. Acute, sudden, short time pain in the parotid gland region with irradiation to the ear during the first bite a meal is a characteristic for this syndrome. The correct diagnosis and individual approach in choosing a treatment method is the key to success in treating this complication. The purpose of our article is to supplement scanty data on this complication in Polish literature.
An overview of Brazilian researches in the Computer Science field in last years

Published: November 2019

Recently, most traditional market services have joined online service platforms. Despite the practicality achieved, such services eventually bring a large amount of data to the Web. In this sense, data analysis, data engineering, and data science activities have become extremely necessary. In general, they can extract extra information about systems and users, allowing the owners to produce insights and analyze patterns. Then, we propose an evaluation methodology to be applied in the online scenario of registration of publications and scientific productions, such as ResearchGate and Lattes Platform of CNPq. This methodology is unsupervised and divided into three main stages: (i) obtaining and representing the data; (ii) application of topic modeling; and (iii) the labeling of topics. This proposal diverges from the literature’s proposes that are based on collaborative networks and supervised techniques. We applied this methodology to a Lattes database and were able to observe the evolution of Computer Science research in Brazil. Based on this analysis, it is possible to identify the most popular and least explored research lines in order to direct public investments according to a certain interest.
Business Process Failure Prediction: a case study
Authors: Mello Pedro O. T. , Revoredo Kate , Santoro Flávia
Published: November 2019

Business process monitoring aims at maintaining the reliability of process executions. However, the dynamic nature of business processes hinders a proactive scenario in which risk mitigation actions can occur before the facts that put the process at risk. Thus, some premises are necessary such as the identification of situations and patterns in historical data of the processes execution in order to characterize what determined the failures. In this paper, we address the problem of how to identify and detect patterns of behaviors that can lead the processes to a failure situation. As a solution, a combination of well-established techniques from Data and Process Mining fields are applied in a case study of an incident management process. The results obtained open possibilities to a proactive scenario.
The Differential Diagnosis of Reparative Changes and Malignancy: Performance in the College of American Pathologists Pap Education and Proficiency Testing Programs

Published: November 2019

Context.—

Repair is a challenging diagnosis and a significant source of false-positive (FP) interpretations in cervical cytology. No large-scale study of performance of repair in the liquid-based era has been performed.

Objective.—

To evaluate the performance of repair in the College of American Pathologists Pap Education and Proficiency Testing (PT) programs.

Design.—

The FP rate for slides classified as repair was evaluated by preparation type, participant type (cytotechnologist, pathologist, or laboratory), and program. The specific misdiagnosis category and individual slide performance were also evaluated. The rate of misclassification of slides as repair by participants for other diagnostic categories in the Pap Education program was assessed.

Results.—

The overall FP rate was 1700 of 12 715 (13.4%). There was no significant difference by program or preparation type. Within the Education program there was no difference by participant type, but pathologists' FP rate in the PT program (47 of 514, 9.1%) was significantly better than cytotechnologists in the PT program (51 of 380, 13.4%) and pathologists in the Education program (690 of 4900, 14.1%). High-grade squamous intraepithelial lesions/cancers (HSIL+) accounted for 1380 of 1602 FP interpretations (86%) in Education, but 43 of 98 (43.9%) in PT. Most slides had a low rate of misclassification, but a small number were poor performers. False-negative diagnosis of HSIL+ as repair was less common, ranging from 0.7% to 1.8%.

Conclusions.—

Despite initial indications that liquid-based cytology might reduce the rate of misclassification of repair, FP interpretations remain common and are no different by preparation type. Misclassification is most commonly as HSIL or carcinoma, potentially resulting in significant patient harm.
Escritos de Comunidades Novas Católicas e as religiões de matrizes africanas em sala de aula: violências religiosas
Authors: Paulo Adriano Ferreira de , Silva Joselina Da
Published: November 2019

Este trabalho versa sobre questões religiosas no campo educacional, considerando que, sendo o Brasil aberto à pluralidade religiosa em sua constituição, comumente traz problemáticas quanto ao pertencimento dos alunos na confissão de suas crenças, ou mesmo na aceitação do outro, se esta crença for diferente do que seja considerado como padrão. Isto fica mais evidente se tomarmos por base as religiões de matrizes africanas - a saber, para esta pesquisa, a Umbanda e o Candomblé - ficando estabelecido um cenário de rejeição pelo estereótipo criado, em âmbito social, a partir de alguns segmentos religiosos, sendo nosso objeto de análise um movimento cristão, católico, advindo do seio do pentecostalismo carismático católico: as Comunidades Novas. Esta pesquisa tem caráter qualitativo, onde foram analisadas fontes escritas das Comunidades Católicas Shalom e Canção Nova, as duas sendo referência neste ambiente católico, em contraste com as orientações dos documentos gerados a partir da lei 10.639/03, sobre valorização da cultura afro-brasileira na educação. Os escritos que partem destas comunidades católicas citadas provocam um olhar de preconceito e discriminação em relação às crenças de matrizes africanas enfocadas neste estudo. Entendemos que se faz necessário um aprofundamento maior por parte dos professores nas causas que envolvem a Lei nº 10.639/2003, para se tornarem agentes no cumprimento da legislação, em favor de ações afirmativas multiculturais, abertas ao diálogo inter-religioso, em que a comunidade escolar é a maior beneficiada nesse processo.
Effectiveness and Duration of Plantar Pressure Off-loading by Two Designs of Felt Padding: A Preliminary Study
Authors: Nieto-Gil María Pilar , Ortega-Avila Ana Belen , Pardo-Rios Manuel , Gijon-Nogueron Gabriel
Published: November 2019

Background:

The aim of this study was to observe the pressure changes in the felt padding used to off-load pressure from the first metatarsal head, the effects obtained by different designs, and the loss of effectiveness over time.

Method:

With a study population of 17 persons, two types of 5-mm semicompressed felt padding were tested: one was C-shaped, with an aperture cutout at the first metatarsophalangeal joint, and the other was U-shaped. Pressures on the sole of the foot were evaluated with a platform pressure measurement system at three time points: before fitting the felt padding, immediately afterward, and 3 days later.

Results:

In terms of decreased mean pressure on the first metatarsal, significant differences were obtained in all of the participants (P < .001). For plantar pressures on the central metatarsals, the differences between all states and time points were significant for the C-shaped padding in both feet (P < .001), but with the U-shaped padding the only significant differences were between no padding and padding and at day 3 (P = .01 and P = .02).

Conclusions:

In healthy individuals, the U-shaped design, with a padding thickness of 5 mm, achieved a more effective and longer-lasting reduction in plantar pressure than the C-shaped design.
From plasmodesma geometry to effective symplasmic permeability through biophysical modelling
Authors: Deinum Eva E , Mulder Bela M , Benitez-Alfonso Yoselin
Published: November 2019

Regulation of molecular transport via intercellular channels called plasmodesmata (PDs) is important for both coordinating developmental and environmental responses among neighbouring cells, and isolating (groups of) cells to execute distinct programs. Cell-to-cell mobility of fluorescent molecules and PD dimensions (measured from electron micrographs) are both used as methods to predict PD transport capacity (i.e., effective symplasmic permeability), but often yield very different values. Here, we build a theoretical bridge between both experimental approaches by calculating the effective symplasmic permeability from a geometrical description of individual PDs and considering the flow towards them. We find that a dilated central region has the strongest impact in thick cell walls and that clustering of PDs into pit fields strongly reduces predicted permeabilities. Moreover, our open source multi-level model allows to predict PD dimensions matching measured permeabilities and add a functional interpretation to structural differences observed between PDs in different cell walls.

Conductance in voltage-gated ion channels is regulated by membrane voltage through structural domains known as voltage sensors. A single structural class of voltage sensor domain exists, but two different modes of voltage sensor attachment to the pore occur in nature: domain-swapped and non-domain-swapped. Since the more thoroughly studied Kv1-7, Nav and Cav channels have domain-swapped voltage sensors, much less is known about non-domain-swapped voltage-gated ion channels. In this paper, using cryo-EM, we show that KvAP from Aeropyrum pernix has non-domain-swapped voltage sensors as well as other unusual features. The new structure, together with previous functional data, suggests that KvAP and the Shaker channel, to which KvAP is most often compared, probably undergo rather different voltage-dependent conformational changes when they open.

«Inn i bildet» er et praksisledet formidlingsprogram som er utformet ved Nasjonalmuseet i Oslo (NM). Innen dette programmet er det utviklet en metode basert på estetiske prosessorienterte tilnærmingsmåter der møtet med et kunstverk starter en aktiv prosess hos betrakteren. «Inn i bildet» viser hvordan kunstbasert læring kan fungere som verktøy for trening av refleksjonsevnen, noe som igjen kan gi forståelse og innsikt både individuelt og som gruppe. Metoden er spesielt egnet for områdene utdanning, arbeidsliv og psykisk helse. Denne artikkelen er en analyse av hvordan arbeidet med et fritt valgt kunstverk bearbeides videre i eget personlig uttrykk. Deltagerne eksperimenterer med ulike teknikker i atelieret, veiledet av kunstpedagoger / Teaching Artist (TA). TA er en profesjonell kunstner som arbeider med kunst i utdanning eller i tilknytning til samfunnsorganisasjoner, i denne sammenheng ved Nasjonalmuseet. Hensikten med artikkelen er å løfte fram formidlingsmetoden, slik at leseren steg for steg får ta del i selve arbeidsprosessen. Relevant teori fra pedagogikk, kunstdidaktikk, antropologi og kunstterapi anvendes for å betrakte praksisledet arbeid med kunstformidling i lys av fenomenologiske og hermeneutiske perspektiv.
Comparative morphology and trophic ecology in a population of the polymorphic lizard Sceloporus minor (Squamata: Phrynosomatidae) from central Mexico

Published: November 2019

Polymorphism among individuals of the same population has generally been linked to alternative reproductive tactics, where different morphs can exhibit differences in their morphological, ecological, and behavioral attributes. These differences may result in a divergence in diet between morphs due to differential exploitation of habitat, morphological differences that influence prey selection, or differential energy expenditure that results in different nutritional needs. The present study analyzes the morphology (morphometry and body mass) and diet of red and yellow male morphs in a population (El Enzuelado) of the lizard Sceloporus minor from central Mexico. No differences between morphs were found for any of the morphometric variables analyzed (snout-vent length, tail length, jaw length, jaw width, head length, head width, head height, tibia length, femur length, forearm length and ventral patch length). In both morphs, allometric growth was observed in all body features analyzed, as well as in morphometric features of the head across seasons. Analysis of stomach contents showed that the diet of red males was composed of 12 categories of prey, while that of yellow males was composed of 10 categories; those categories of diet not shared between morphs (e.g., Isoptera, Psocoptera) were consumed by their respective morph in very low proportions. Categories of diet with the highest values of food importance for both groups were Coleoptera, Orthoptera, and leaves; a similar pattern was seen across seasons. This, in turn, is reflected in low niche breadth values for each morph and a very high niche overlap. There were no significant differences between morphs overall, or between morphs per season, in the weight and volume of stomach contents or in the number of prey items found in stomachs; however, differences in these variables across all males (independent of morph) were recorded between seasons. Likewise, no significant correlations were found between body size (snout-vent length) and the volume of stomach contents for either morph or between lizard mandibular dimensions and the volume of stomach contents for red morph males. For the yellow morph, prey volume unexpectedly decreased significantly with jaw size rather than increasing as expected. Overall, this study adds new information about the morphology and feeding of males in this species, and suggests that in this population, color morphs lack the morphological and ecological differences found in some other species of polymorphic lizard.

Background: Cotton (Gossypium hirsutum L.) is the most important fiber crop of the world and commonly known as white gold. It plays an important role in the economy of Pakistan. It provides raw material to the local textile industry and generates considerable amount of foreign exchange. The yield of cotton is lower in Pakistan. Knowledge of association among different traits is important for the development of cultivars with better yield and quality characters.

Materials and Methods: In this research, two parents (PB-38 and Jambo Okra) and their crosses sown in randomized complete block design with three replications to sort out best performing genotypes for these profitable traits (plant height, number of sympodial branches, number of monopodial branches, leaf type, boll size, boll shape, number of bolls per plant, boll weight, ginning out turn, 100 seed weight and seed cotton yield).

Results: Analysis of variance (ANOVA) revealed that parental and their F2 population showed significant differences for all the observed traits. Correlation and inheritance pattern of all characters provides information of association among all traits and percentage of inheritable attributes.

Conclusions: The association and inheritance pattern study provide us useful information for effective selection and sustainable breeding programs. Heritability estimations revealed that heritability of traits fluctuate as following order; monopodial branches> ginning outturn>boll weight>sympodial branches>plant height>yield>number of bolls plant-1 with heritable percentages 99%, 90%, 89%, 64%, 60%, 60% and 55% respectively.

Aims: The present study was designed to develop and validate the UHPLC method for quantitative determination of roxithromycin, a macrolide antimicrobial drug, in broiler plasma for the application of pharmacokinetic studies.

Methodology: UHPLC apparatus comprised of ultraviolet (UV) detector was used in the present study. Chromatographic separation was performed by using reverse phase C18 column. Mobile phase was combination of buffer and 55 acetonitrile in the ratio of 55: 45. Buffer part used was 0.1% trifluoroacetic acid (v/v) having pH of 2.1. Erythromycin was used as an internal standard. Isocratic elution mode was employed with flow rate of 1 ml/min and effluents were monitored at wavelength of 220 nm. Liquid-liquid extraction using ice-cold acetonitrile was performed to extract roxithromycin from plasma samples. The data integration was performed using Chromeleon™ version 6.8 software.

Results: The linear calibration curve with a mean correlation coefficient (R2) value of 0.9999 was observed for concentrations ranging from 0.20 to 12.80 µg/ml. At any concentration, accuracy was not found to be less than 90%. The mean extraction recovery (n=5) for concentrations of 0.40 µg/ml was 81.36%. The calculated intraday and interday C.V. % was not more than 7.70% and 9.42%, respectively, at any concentration studied. The specificity of the analysis was reflected by the narrow range of retention time ranging between 6.983 to 7.178 minutes. LOD and LOQ of the method under investigation were calculated as 0.131 and 0.398 µg/ml, respectively.

Conclusion: A reliable, reproducible, accurate, precise, specific and sensitive method for analysis of roxithromycin in broiler plasma was developed and validated for application in the pharmacokinetic study of the roxithromycin.

Detectors
Authors: Ham Ronald E.
Published: December 2024

Microwave energy cannot be effectively detected with equipment used for lower frequency applications. Changes in microwave frequency voltage are too rapid to be captured on any but the fastest sampling oscilloscopes, and response time and parasitics of common test meters render them useless. Microwave detectors measure power in controlled impedance environments afforded by transmission lines and waveguides. Since the system impedance is known, voltage and current magnitudes can be derived. With the judicious application of other microwave components such as power splitters and quadrature couplers, phase information can be extracted from multiple power measurements; therefore, complete characterization of a system or component is possible with only microwave detectors to convert microwave signal characteristics into readily observable and measurable quantities of low‐frequency voltages and currents.
Signal Integrity
Authors: Peterson Zachariah
Published: December 2024

Signal integrity in radio frequency (RF) systems encompasses several design, measurement, and analysis techniques used to evaluate the quality of a signal transmitted through a high‐frequency channel. Analysis techniques involve the use of frequency‐domain transfer functions and network parameters, which can be used to design interconnects with the desired impedance and propagation characteristics. In this chapter, the foundational definitions, electronic design concepts, and analytical frameworks will be introduced and reviewed. Remarks regarding the applicability and relations between such signal integrity metrics are provided to give readers an overview of signal integrity practices used in academia and industry. A section on S‐parameters and network parameter analysis is included to highlight the applicability and physical interpretation of this fundamental network parameter set. Finally, signal integrity challenges associated with nonlinear systems, namely, power amplifiers, will be presented at the end of the manuscript.
