Authors: Coverdale Rangel Velasco David , Da Silva Almeida Saymon , Mendes Almeida Thais , Barreto Hygino Machado Cassiana
Published: January 2022

O ensino de disciplinas com cálculos extensos e complexos tem sido um desafio, sobretudo no Ensino a Distância. Neste sentido, diversos educadores têm avaliado formas de otimizar o ensino, sobretudo nos últimos anos durante a pandemia da COVID; que forçou milhões de professores a migrarem para o ensino remoto. A utilização de planilhas eletrônicas, por exemplo, possui o potencial de gerar ganhos de qualidade e produtividade nas mais diversas áreas e níveis de ensino. Este trabalho busca avaliar a utilização deste recurso na engenharia mecânica ao automatizar ações já estudadas, como conversão de unidades, aplicação de fórmulas e focar na discussão dos novos conteúdos abordados na aula. A pesquisa foi aplicada em um grupo de 28 alunos, sendo 17 (60%) a quantidade que respondeu o questionário. Por meio desta pesquisa foi possível observar uma boa adesão da ferramenta pelos alunos, sendo todas as respostas neutras ou positivas, com média de 4,65 em uma escala de 1 a 5. Acrescenta-se ainda que, embora a pesquisa fosse realizada por meio de aulas remotas, os alunos manifestaram interesse que este recurso continuasse a ser utilizado presencialmente. Assim, espera-se que a partir dos resultados satisfatórios obtidos nesta pesquisa, planilhas eletrônicas possam ser utilizadas por outros docentes em diferentes modalidades de ensino.

Published: January 2022

Com o uso de frequente acompanhamento, feedbacks sobre a aprendizagem dos estudantes e a proposta de um ensino personalizado, a Sala de Aula Invertida vem ganhando espaço nas disciplinas de ciências exatas. Personalizar o ensino não é tarefa fácil e os recursos tecnológicos são uma das alternativas para que professores consigam fazer com agilidade e eficiência. Este artigo é um recorte de uma dissertação de mestrado que objetivou construir e validar o FrameAGAP, um framework para gestão e acompanhamento de aprendizagens personalizadas, para o conteúdo de cônicas, utilizando como metodologia de pesquisa o Design Experiment. Nele, discutem-se as possibilidades do FrameAGAP quanto ao acompanhamento da aprendizagem de uma estudante com dificuldades no estudo das seções cônicas. Como resultados, verificamos que o FrameAGAP possibilitou que estudantes recebessem feedback sobre as atividades propostas, além de recursos e situações que os possibilitaram explorar e mobilizar os conhecimentos necessários para a aprendizagem do conteúdo de cônicas.
A LIBERDADE NÃO TIRA FÉRIAS: BRINCAR LIVRE, LUDICIDADE E EDUCAÇÃO INFANTIL
Authors: Porto Bernadete de Souza , Pinto Georgia Albuquerque de Toledo
Published: January 2022

Este trabalho debate o brincar livre como um caminho didático a alicerçar a relação entre adultos de referência e crianças, a partir da concepção de uma criança potente e capaz de construir saberes de forma autônoma e independente. A pesquisa relatada tem cunho etnográfico (ANDRÉ, 1995) e os dados para análise foram coletados através de observações, filmagem e diário de campo até a produção de uma análise microgenética realizada dentro do espaço físico escolar. Busca-se desmistificar a polaridade entre atividade lúdica e sistemática fazendo-nos olhar para os processos de integração das culturas lúdica, infantil e educativa. Do mesmo modo, pressupõe-se que os elementos que distinguem as atividades lúdicas das sistematizadas podem ser revelados através do grau de iniciativa e protagonismo das crianças ao realizá-las. Entende-se que o brincar parece mais livre que uma atividade sistemática, por possuir polissemia aberta. Curiosamente, a análise de algumas situações gravadas mostrou-nos que, quando é resguardada à criança a liberdade de escolher o processo de realização dessas atividades, a atividade sistemática também oferece abertura polissêmica tanto quanto as atividades lúdicas.

Published: January 2022

O presente artigo traz uma abordagem sobre o livro de imagem como um instrumento norteador no ensino e aprendizagem de crianças, em uma perspectiva de literatura infantil fluente no aprendizado, salientando a sua importância no desenvolvimento da criança. Tratamos também do livro literário infantil como instrumento metodológico que favorece o desenvolvimento do trabalho docente no processo de ensino e aprendizagem, se for utilizado com significado para a criança. A pesquisa também contemplou a análise do livro de Ruth Rocha, “O menino que aprendeu a ver”, e do livro de Elias José, “As histórias e os lugares”. Esses livros foram escolhidos por terem imagens que envolvem o cotidiano e por serem utilizados em escolas da rede pública de ensino. A fundamentação teórica utilizada pauta-se em autores como Bom-Fim (2009), Freire (1989), José (2002) e demais autores do campo da educação que nos permitem falar da escrita ilustrada como um meio norteador para o desenvolvimento da linguagem e da leitura da criança com base nas visualizações de imagens. Com base nas análises realizadas, percebemos que o uso adequado das ilustrações no âmbito escolar pode ser um passaporte para o mundo da leitura de palavras, da produção de textos e de narrativas diferenciadas.
O BRINCAR NO MULTILETRAMENTO ENGAJADO PARA A CONSTRUÇÃO DE PRÁTICAS INSURGENTES
Authors: Liberali Fernanda Coelho , Mazuchelli Larissa Picinato , Modesto-Sarra Luciana Kool
Published: January 2022

Ancorado na luta decolonial, que busca superar o exercício de poder que sustenta políticas de exclusão e morte (SANTOS, 2018), conhecido como necropolítica (MBEMBE, 2016), este artigo articula os conceitos de brincar e atividade (VYGOTSKY, 1933/1991; 1934/1994), integrado às ideias Freirianas, para contextualizar uma prática política de multiletramento. O Multiletramento Engajado (LIBERALI, 2021) propõe ir além da compreensão das injustiças e desigualdades da realidade, buscando superá-las como parte da proposta pedagógica. Para este trabalho, analisamos o planejamento, trocas via WhatsApp e a videogravação de um encontro realizado virtualmente durante a pandemia de Covid-19 pelo Projeto Brincadas que tematizou a realidade, a luta e o orgulho LGBTQIA+. De maneira geral, a discussão e análise apresentadas mostram como essa prática insurgente de formação cria, por meio do brincar, instrumentalidades (ENGESTRÖM, 1987/2016) de enfrentamento da colonialidade e alicerça caminhos para a construção de novos sentidos e experiências na busca pelo Bem Viver (KRENAK, 2020a).

Published: January 2022

O texto possui como foco de investigação a inserção da Língua Brasileira de Sinais (Libras) como disciplina para alunos surdos e ouvintes, no município de Castanhal-Pa. A construção do referencial teórico parte do paradigma da educação inclusiva e de autores como Quadros (2008), Lacerda (2006), Barbosa (2011), Strobel (2008), Vasconcelos (2006), Cavalcante (2010), Gesser (2009) entre outros. A metodologia segue a abordagem qualitativa e se constitui como um estudo de caso, triangulado por uma pesquisa bibliográfica e documental. A coleta de dados foi realizada por meio de entrevistas semiestruturadas com três sujeitos que participaram ativamente do processo de implementação da Libras no município citado. Os resultados do estudo evidenciam os principais atores, as instituições, processos e tensões que resultaram na inserção da Libras na rede municipal de ensino de Castanhal. As conclusões indicam as potencialidades da inserção de Libras no currículo municipal, bem como suas limitações, do ponto de vista da educação bilingue, evidenciando a existência de desafios para a consolidação de uma real educação inclusiva no nordeste paraense.
SABERES LUDO-SENSÍVEL E SABERES PRÁTICO-POIÉTICOS
Authors: Lemos Elson de Souza
Published: January 2022

O estudo sobre a relação entre saber ludo-sensível e saber prático-poiético tem origem na seguinte questão de pesquisa: qual a relação entre saber ludo-sensível e saber prático-poiético? E tem por objetivos: analisar a relação entre saber ludo-sensível e saber prático-poiético e como objetivos específicos: discutir como se produz o saber ludo-sensível e o saber prático-poiético; e descrever a relação entre saber prático-poiético com o saber ludo-sensível. Metodologicamente a pesquisa é de natureza teórica e caracteriza-se como exploratória. A metodologia consistiu em reflexões de abordagem qualitativa, de procedimento bibliográfico. Fundamentou-se em autores: como Brougère (1998), Cabral (2021), Castoriadis (1992), Chaui (2000), Duarte Jr. (2001), Grillo; Rodrigues; Navarro (2019), Laville e Dionne (1999), Lima; D’Àvila (2013), Lima (2014), Luckesi, (2002; 2007), Mineiro e D’Ávila (2019), Pereira; Cardoso; Santos (2020) e Souza (2015). Os resultados alcançados apontam que há uma estreita relação entre o saber ludo-sensível e o saber prático-poiético. Na produção do saber ludo-sensível, evoca-se o saber prático-poiético, como desencadeador do fazer criativo no âmbito da liberdade e autonomia do sujeito. As conclusões indicam que a atividade lúdica e a prático-poiética, se inscrevem num sistema de significação, que só podem ser interpretadas, em virtude do universo de imagem subjacente, a linguagem dos que estão implicados no contexto.

Authors: Santos Danyelle Moura dos , Santos Nataly Ferreira Costa dos
Published: January 2022

O presente trabalho tem o intuito de refletir acerca do direito e da importância das brincadeiras e do desenho livre na educação infantil. O brincar e o desenhar se constituem como atividades primordiais nessa etapa de ensino, posto que, a criança irá se desenvolver de forma integral nos seus aspectos físico, social, cultural, afetivo e cognitivo. Desta maneira, este estudo vai propiciar uma leitura mais consciente acerca da relevância do brincar e do desenhar na vida do ser humano, especialmente na vida da criança. Por meio deste trabalho chegamos a conclusão que se faz necessário que os professores reconheçam a importância do brincar e do desenhar livre no ambiente escolar infantil, visto que, é sabido que as atividades lúdicas contribuem para o desenvolvimento infantil e, portanto, cabe às instituições de ensino e aos professores enfatizarem esta prática com a intencionalidade voltada para o processo de aprendizagem dos educandos. Para tal, recorremos aos pressupostos da pesquisa bibliográfica e estudos sobre o tema, dialogando com alguns teóricos, com documentos orientadores e com os conhecimentos adquiridos durante a nossa trajetória acadêmica. Foi realizada uma revisão bibliográfica do tema que possibilitou fundamentar o estudo. Trata-se de uma abordagem qualitativa e consiste em pesquisa exploratória.

Authors: Carmo Silva Zelania , Eugenio Benedito
Published: January 2022

Este artigo apresenta os resultados de um estado do conhecimento que objetivou efetuar o levantamento e a análise de trabalhos publicados em periódicos do campo do currículo e que abordassem “Política curricular e Relações étnico-raciais na educação básica”, produzidos no período de 2003 a 2018. Foram selecionados artigos que analisem as categorias citadas na perspectivas discursiva da teoria do discurso de Laclau e Mouffe. O corpora foi constituído por publicações das Revistas Currículo sem Fronteiras e E-currículum e para a organização dos dados estudo empregamos a análise de conteúdo (BARDIN, 2016). As considerações finais apontam que os trabalhos dedicados ao estudo da política curricular para a educação étnico-racial ainda privilegiam a investigação da política no contexto da prática pedagógica e a perspectiva discursiva de análise do currículo ainda ocupa espaço incipiente nas publicações dos periódicos específicos sobre o currículo no período analisado.
Less invasive treatments for pure aortic insufficiency: Are we there yet?
Authors: Forcillo Jessica
Published: January 2022

The gold standard for the treatment of pure aortic insufficiency (PAI)
is surgical valve repair or replacement.1 With the newest transcatheter
heart valve technologies and the accumulating years of experience of
heart teams with the current transcatheter aortic valve replacement
(TAVR) prostheses, implanters have push the envelope with off-label use
of those valves designed and approved for aortic stenosis, in patients
with pure aortic insufficiency especially those at higher risks or for
compassionate use.3 However, new prostheses are currently under
investigation in clinical use and evidences are provided on the safety
and efficacy of those latter. It will be discussed in this commentary,
the actual clinical evidences and the use of transcatheter heart valves,
in and off label, for the treatment of pure aortic insufficiency.

Published: January 2022

Background and aim of the study To evaluate whether the release
and perfuse technique implies a circulatory arrest time comparable with
or shorter than those of standard Frozen Elephant Trunk technique in
aortic arch surgery. Methods We retrospectively reviewed the
records of patients who had undergone aortic arch repair with Release
and Perfuse Technique (RPT) or standard Frozen Elephant Trunk (FET) at
our Institution between January 2018 and May 2021. Primary endpoints
were the comparison of circulatory arrest time, perioperative variables,
and complications between two groups. A propensity score weighting
approach was used for data analysis. Results A total of 41
patients underwent aortic arch surgery were analyzed:15 (37%) and 26
(63 %) in RPT and FET group, respectively. The use of RPT showed a
significant shorter circulatory arrest times than FET: 9 min vs 58 min
(P < 0.001), respectively. The median lactates peak in the
first 24h post intervention was 2.6 for RPT group and 5.4 mmol/L for FET
group, (P <0.0001). When compared with the FET, RPT is
associated with significant reduction in the use of packed red blood
cells (P <0.0001), fresh frozen plasma (P <0.0001),
platelet concentrate (P <0.0001), and fibrinogen (P
<0.004). The median ICU stay was 3 and 9 days (P = 0.011),
whereas the median hospital stay was 12 and 18.5 days (P=0.004) in the
RPT and FET groups, respectively. Thirty-day mortality and postoperative
outcomes were comparable between the two groups. Conclusions
Considering the anatomical limitations related to the use of this
technique, the RPT appears to be safe, feasible, and effective in
reducing the circulatory arrest time during aortic arch surgery.
Nevertheless, further studies are required to demonstrate its safety and
efficacy.
Reactivity thresholds in children allergic to cow's milk and egg, but tolerant of baked milk and baked egg.

Published: January 2022

Background. The use of eliciting doses (EDs) for food allergens
is necessary to inform individual dietary advice and food allergen
risk-management. The Eliciting Dose 01 (ED01) for milk and egg,
calculated from populations of allergic subjects undergoing diagnostic
Oral Food Challenges (OFCs), are 0.2 mg total protein. The respective
Eliciting Dose 05 (ED05) are 2.4 mg for milk and 2.3 mg for egg. As
about 70% children allergic to such foods may tolerate them when baked,
we sought to verify the EDs of that subpopulation of milk and
egg-allergic children. Methods. We retrospectively assessed
consecutive diagnostic OFC for fresh milk and egg between January 2018
and December 2020 in a population of baked food-tolerant children.
Results. Among 288 children (median age 56 - IQR 36-92.5
months, 67.1% male) included, 87 (30.2%) returned positive OFC
results, 38 with milk and 49 with egg. The most conservative ED01 were
0.3 mg total protein (IQR 0.03-2.9) for milk and 14.4 mg total protein
(IQR 3.6-56.9) for egg. The respective ED05 were 4.2 (IQR 0.9-19.6) mg
for milk and 87.7 (IQR 43-179) mg for egg. Such thresholds are
respectively 1.5 (milk ED01), 1.75 (milk ED05), 72 (egg ED01), and 38.35
(egg ED05) times higher than the currently used thresholds.
Conclusions The subpopulation of children allergic to milk and
egg, but tolerant to baked proteins, displays higher reactivity
thresholds than the general population of children allergic to milk and
egg. Their risk stratification, in both individual and population terms,
should consider this difference. In baked milk-tolerant children, milk
causes reactions at lower doses than egg in our group of egg-tolerant
children. This could be associated with the relative harmlessness of egg
compared to milk in the determinism of fatal anaphylactic reactions in
children

Published: January 2022

Objective: Type 2
diabetes (T2D) is a leading cause of end stage kidney disease
(ESKD) worldwide. Recent studies suggest a more aggressive clinical course of
diabetic kidney disease (DKD) in youth-onset than adult-onset T2D. We compared kidney
structural lesions in youth- and adult-onset T2D to determine if youth-onset
was associated with greater early tissue injury.

Methods: Quantitative microscopy
was performed on kidney tissue obtained from research kidney biopsies in 161
Pima Indians (117 women, 44 men) with T2D. Onset of T2D was established by
serial oral glucose tolerance testing and participants were stratified as
youth-onset (<25 years) or adult-onset (≥25 years). Associations between clinical
and morphometric parameters and age of onset were tested using linear models.

Results: At biopsy, the 52 participants
with youth-onset T2D were younger than the 109 with adult-onset T2D (39.1±9.9 vs.
51.4±10.2 years, p<0.0001), but their diabetes duration was similar
(19.3±8.1 vs. 17.0±7.8 years, p=0.09). Median urine
albumin-to-creatinine ratio was higher in the youth-onset group (58 [25th-75th
percentile, 17-470]
vs. 27 [13-73] mg/g, p=0.02). Youth-onset participants
had greater glomerular basement membrane (GBM) width (552±128 nm vs. 490±114nm,
p=0.002) and mesangial fractional volume (0.31±0.10 vs. 0.27±0.08,
p=0.001) than adult-onset participants. Percentage glomerular sclerosis,
glomerular volume, mesangial fractional volume, and GBM width were also inversely
associated with age of diabetes onset as a continuous variable.

Conclusion: Younger age
of T2D onset strongly associates with more severe kidney structural
lesions. Studies are underway to elucidate
the pathways underlying these associations.
Cytotoxicity-related Gene Expression and Chromatin Accessibility Define a Subset of CD4+ T Cells that Mark Progression to Type 1 Diabetes

Published: January 2022

Type 1 diabetes in children is heralded by a
preclinical phase defined by circulating autoantibodies to pancreatic islet
antigens. How islet autoimmunity is initiated and then progresses to clinical
diabetes remains poorly understood. Only one study has reported gene expression
in specific immune cells of at-risk children, associated with progression to islet
autoimmunity. We analysed gene expression by RNAseq in CD4+ and CD8+
T cells, NK cells and B cells, and chromatin accessibility by ATACseq in CD4+
T
cells, in
five genetically at-risk children with islet autoantibodies who progressed to
diabetes over a median of 3 years (‘Progressors’) compared to five children
matched for sex, age and HLA-DR who had not progressed (‘Non-progressors). In Progressors,
differentially expressed genes (DEGs) were largely confined to CD4+
T cells and enriched for cytotoxicity-related genes/pathways. Several top-ranked
DEGs were validated in a semi-independent cohort of 13 Progressors and 11 Non-progressors. Flow
cytometry confirmed progression was associated with expansion of CD4+ cells
with a cytotoxic phenotype. By ATAC-seq, progression was associated with reconfiguration
of regulatory chromatin regions in CD4+ cells, some linked to differentially
expressed cytotoxicity-related
genes.
Our findings suggest that cytotoxic CD4+ T cells play a role in promoting
progression to type 1 diabetes.

Zur Fruchtberostung 2018
Authors: Martin Thalheimer
Published: January 2022

Die Fruchtberostung bei Äpfeln wird durch eine Schädigung der Fruchtepidermis verursacht und entsteht durch die Verkorkung der geschädigten Zellbereiche. Die möglichen Ursachen für die Schädigung der Fruchtoberfläche sind vielfältig und können komplexen Wechselwirkungen unterliegen. Während einige Formen der Fruchtberostung (Frostringe, Frostzungen) eindeutig auf Frost als auslösenden Faktor zurückgeführt werden können, wird diffuse Berostung durch verschiedene Einflussfaktoren verursacht und kann folglich nicht eindeutig spezifischen klimatischen Ereignissen zugeordnet werden. Auch bei der im Jahr 2018 im Südtiroler Apfelanbau verbreitet aufgetretenen Fruchtberostung mit vorwiegend diffuser Ausprägung ist es demnach nicht möglich, eine eindeutige Ursache als auslösenden Faktor zu ermitteln.
Die Anbaueignung von sechs Rebsorten im Südtiroler Überetsch
Authors: Ulrich Pedri
Published: January 2022

Es wurden für das Weinbaugebiet im Südtiroler Überetsch in den Jahren 2004 bis 2006 Rebsorten als Ersatz oder Ergänzung für die autochthone Rebsorte Vernatsch untersucht, die sich entweder zum sortenreinen Ausbau oder als Verschnittpartner dafür eignen könnten. Es wurden die sechs Sorten Merlot, Diolinoir, Tempranillo, Rebo, Teroldego und Viognier an vier verschiedene Standorten geprüft. Die analytischen Unterschiede der Sorten sind dermaßen, dass einzelne Sorten klar von anderen unterschieden werden können. Die Standortansprüche sind z.T. sortenabhängig. Grundsätzlich sind die Standorteinflüsse während des Beobachtungszeitraumes auf die Jungweine eher marginal bis verschwindend klein. Dennoch verlangt z.B. Tempranillo mehr Aufmerksamkeit hinsichtlich der Standortwahl als Teroldego oder Merlot. Von den analytischen Werten ähnelt Tempranillo am ehesten der Sorte Vernatsch, während sowohl Teroldego, Diolinoir als auch Rebo davon relativ weit entfernt sind. Teroldego hat eine große Ähnlichkeit mit der Sorte Lagrein. Die Ergebnisse zeigten eine grundsätzliche Eignung der geprüften Sorten, mit einigen wenigen Einschränkungen, für den Anbau in besagten Gebiet.

Published: January 2022

Südtirol ist seit jeher ein Land der vielen verschiedenen Rebsorten. Viele Sorten sind im Laufe der Jahre aus den verschiedensten Gründen angebaut aber auch wieder entfernt worden. Nach wie vor gibt es aber auch in Südtirol einen Nischenmarkt für alte historische Lokalsorten, von denen ein Restbestand besteht und die entweder reinsortig oder im Verschnitt ausgebaut werden. Allerdings scheinen einige dieser Sorten in keinem Sortenkatalog auf. Dieses Projekt dient zur Ausarbeitung eines Dossiers für die Sorten Fraueler, Versoalen, Weissterlaner, Blatterle und Furner, um diese in den Nationalen Rebsortenkatalog eintragen zu lassen.
Auswirkungen der Nacherntebehandlung mit Schellack auf Äpfel der Sorten Red Delicious und Fuji
Authors: Angelo Zanella
Published: January 2022

Die Nachernte-Beschichtung von Früchten mit Schellack verbessert deren Aussehen. Zudem könnte die innere Qualität besser erhalten und physiologischen Störungen, wie z.B. der gewöhnliche Schalenbräune, vorgebeugt werden. Während eines zweijährigen Versuches wurde im Versuchszentrum Laimburg der Einfluss einer Schellack-Behandlung an den Sorten Red Delicious und Fuji bei unterschiedlichen Varianten überprüft. Ausgewertet wurden die Qualitätsunterschiede zwischen gewachsten und ungewachsten Früchten nach einer Lagerung in CA-ULO, CA-ULO mit 1-MCP (SmartFresh) oder in dynamisch kontrollierter Atmosphäre mittels Chlorophyll-Fluoreszenz-Sensoren (DCA-CF). Bei gewachsten Früchten der Sorte Red Delicious konnte nach 7 Tagen Shelf Life neben einer höheren Festigkeit auch eine Hemmung des Wasserverlustes und der gewöhnlichen Schalenbräune beobachtet werden. Bei behandelten Früchten der Sorte Fuji konnte bestätigt werden, dass die Lentizellen-Schwäche (lenticel breakdown) auf den Temperaturschock während der Wachsbehandlung zurückzuführen ist und nicht auf die Behandlung selbst.

Published: January 2022

Die Tätigkeit des Versuchszentrums Laimburg zur Sammlung der noch erhaltenen Landsorten in Südtirol hat zur Entstehung einer relativ umfangreichen Sammlung der wichtigsten Getreidearten der Alpen geführt. Die Erkennung von Duplikaten und die Quantifizierung der Ähnlichkeit zwischen den Landsorten ist eine zentrale Frage, um die Vielfalt der Sortimente bewerten zu können. Im Rahmen des Interreg III A Projektes GENE-SAVE wurden 89 Landsorten phänotypisch beschrieben, die zwischen 1993 und 2008 in Südtirol gesammelt wurden und aktuell in der Genbank des Landes Tirol gesichert sind. Die Bewertung der phänotypischen Vielfalt mit Methoden der beschreibenden Statistik zeigte, dass Beschreibungen aus unterschiedlichen Jahren und/oder Standorten untereinander nicht vergleichbar sind. Die phänotypische Charakterisierung der Sortimente sollte daher an einem einzigen Standort in einem einzigen Jahr erfolgen. Bei der Betrachtung der Ergebnisse einzelner Versuche wurde eine relativ hohe Diversität mit nur wenigen möglichen Duplikaten gefunden. Nur in einem Fall konnten die Passportdaten das Vorkommen der Duplikate erklären. Dank ihrer Vielfalt stellen die Landsorten ein wichtiges Genreservoir für die Zukunft dar. Die phänotypische Beschreibung kann die Informationen der genetischen Charakterisierung ergänzen oder eine „technologiearme“ Alternative darstellen.
Die Optimierung des Weinausbaues von Cabernet Cortis
Authors: Christoph Patauner  , Ulrich Pedri  , Christof Sanoll
Published: January 2022

Teilresistente Rebsorten stellen eine Möglichkeit dar, mit geringem Pflanzenschutzaufwand zu einer erfolgreichen Ernte zu gelangen. Allerdings sind die weinqualitativen Eigenschaften häufig nicht zufrieden stellend. Die Sorte Cabernet Cortis stellt eine gültige Alternative zu einem alterungsfähigen Rotwein des Cabernettyps dar. Der Weinausbau selbst ist noch zu optimieren, da die Sorte eine sehr markante Gerbstoffkomponente aufweist, die es abzurunden gilt. Auch die typisch fruchtigen Komponenten gilt es besser zu interpretieren. Aus diesem Grund wurden Trauben der Sorte Cabernet Cortis verschiedenen Maischekontaktzeiten und Temperaturverläufen unterzogen.

Published: January 2022

In dieser Arbeit wurden anhand von Daten aus den Jahren 1991-2018 Trocknungsfaktoren für sieben in Südtirol angebaute Kräuterarten bestimmt und mit Werten aus der Literatur verglichen. Anhand von diesen Daten können Referenzwerte für die Berechnung der zulässigen Rückstandsgehalte für Kräuter im getrockneten Zustand bereitgestellt werden. Um den Einfluss der Probennahme und die Reproduzierbarkeit von Rückstandsanalysen bei einer getrockneten Kräutermischung zu untersuchen, wurden eine Reihe von Rückstandsanalysen an kommerziellen und extra gemahlenen Proben einer Mischung mit neun Kräuter-Komponenten durchgeführt. Es konnte eine hohe Reproduzierbarkeit der Rückstandanalysen bei einer Kräutermischung mit einer Kontamination mit dem Wirkstoff Chlorpyrifos-ethyl gezeigt werden. Die Probennahme hat keinen nennenswerten Einfluss auf die Rückstandsanalysen und stellt laut den vorliegenden Ergebnissen keine Ursache für erhöhte oder unplausible Rückstandswerte in Kräutern dar.
Einsatz von Hefederivaten zur Steigerung der phenolischen Reife und Aromaintensität von Wein
Authors: Christoph Patauner  , Christof Sanoll
Published: January 2022

Nach wie vor ist die Steigerung des Aromas durch weinbauliche oder önologische Maßnahmen beim Weißwein eine Herausforderung für die Weinproduzenten. Dasselbe gilt für die Steigerung der phenolischen Reife und Farbausbeute bei Rotwein. Ganz speziell spielen diese beiden Ansprüche in Jahrgängen, die Gefahr laufen, Trauben wachsen zu lassen mit ungenügender Reife eine entscheidende Rolle. In der Weinwirtschaft sind jüngst Produkte aus selektionierten Hefederivaten im Angebot. Diese speziell entwickelten Hefederivate werden mit zwei Spritzungen auf die gesamte Laubwand, die erste bei Weichwerden der Beeren und die zweite im Abstand von 10-14 Tagen, direkt im Weinberg angewendet. Welche Wirkung genau durch diese Hefederivate hervorgerufen wird ist noch nicht ganz geklärt. Laut Hersteller aber sollen sie grundsätzlich bei weißen Traubensorten das Weinaroma intensivieren und bei roten Traubensorten die Phenolische Reife verbessern. Durch dieses Projekt wurde diese Möglichkeit der Aromasteigerung und Verbesserung der Phenol-Struktur angewandt und das Ausmaß der Veränderung gemessen.Das Produkt "LalVigne® Aroma" von Lallemand wurde dabei auf neutralen und aromatischen Weissweinsorte getestet, das Produkt "LalVigne® Mature" von Lallemand hingegen auf schweren Rotweinsorten.
Blühtermine alter und neuer Apfelsorten in Südtirol

Published: January 2022

Eine geeignete Pollenspendersorte muss nicht nur einen kompatiblen Pollen zur Hauptsorte aufweisen, sondern die Blühperiode beider Sorten sollte sich auch ausreichend überschneiden. Der Blühtermin ist entscheidend für die Befruchtung der Apfelblüte und beeinflusst somit den Ertrag und die Fruchtqualität. Es stellt sich unter anderem die Frage, ob neue vielversprechende Sorten wie z.B. Minneiska (SweeTango®) oder WA 38 (Cosmic Crisp®) mit den Südtiroler Hauptsorten wie Gala, Golden Delicious oder Cripps Pink (Pink Lady®) eine ausreichende Überschneidung der Blühperiode aufweisen und somit ohne zusätzlichen Pollenspender angebaut werden können. Am Versuchszentrum Laimburg wurden die Blühtermine von 236 verschiedenen Apfelsorten mit einer standardisierten Methode erhoben. Es handelt sich dabei um alte Lokalsorten, die aktuellen Hauptsorten und neue Sorten.

Authors: Florian Haas  , Barbara Raifer
Published: January 2022

Die Sorte Gewürztraminer wird bekanntlich schon seit geraumer Zeit von den zwei phsyiologischen Störungen Stiellähme und Welketrauben befallen. Im Laufe der Reifephase des Jahres 2014 trat eine weitere Art der Reifestörung bei Gewürztraminer in Südtirol auf. Auffallend war, dass nicht alle Beeren den normalen Reifeprozess durchlaufen, sondern einzelne Beeren grün bleiben. In diesem Artikel werden die Ergebnisse der ersten Ursachenerforschung, sowie daraus hervorgehende erste Lösungsansätze dargestellt. Eine Behandlung mit Magnesium-Blattdünger ergab bis nun die erfolgversprechendsten Ergebnisse.
Lithic Raw Material Procurement in the Late Neolithic Southern-Transdanubian Region: A Case Study From the Site of Alsónyék-Bátaszék
Authors: Szilágyi Kata
Published: January 2022

This article summarizes the current state of research on the flaked stone assemblages from the Late Neolithic site Alsónyék‒Bátaszék, Tolna district. The raw material distribution of the nearly 6100 pieces that make up the stone tool assemblage is the focus of this paper, with a particular emphasis placed on the dominance of the local raw material. The research addresses the question of the method of procurement of the lithic raw material in the case of this enormous, extended Neolithic site. To supply an answer, basic geoarchaeological research was necessary. To that end, a field survey aimed at detecting those geological formations and lithic variations convenient for knapping was undertaken. The results of the survey reported in the second part of this paper help in our understanding of the selection strategy of the ancient knapping specialists. From these strategies, it is possible to recognize the cultural tradition and raw material manipulation of this Late Neolithic community and, in a wider sense, the southeastern group of the Lengyel culture

Authors: Lepionka Hubert
Published: January 2022

The aim of the article is to present and characterize the collection of flint axes made of Cretaceous flint from the interfluve of the Bug River and Neman that morphologically resemble the forms from the Neolithic cultures of the Polish Lowland (the Funnel Beaker Culture, Globular Amphorae Culture and Corded Ware Cultures). This group of objects consists of 10 items found in the Podlasie region. The presented axes are a small part of a large collection (50 flint axes) exhibited in the Museum of Podlasie in Bialystok. A new term for local Cretaceous flint has been introduced for the purpose of this study. Until now, this type of flint was known as Northeastern Flint, and although research to define this term has been done, it has never been fully finalized. Because of that, the author of this study has coined a new and more suitable term: Cretaceous flint from the interfluve of the Bug River and Neman. This includes a group of Cretaceous flints from the Podlasie area and contains all the local variations of it: Mielnik flint, Rybniki flint, flint from the Cretaceous beds and marls and Krasne Siolo flint

As the impact of the Covid-19 pandemic, distance learning requires teachers to make learning more interesting yet achieve learning outcomes. This study aims to produce a valid, practical, and effective product in mobile learning based on procedural and conceptual knowledge for elementary school students. This study uses Research and Development with the ADDIE model. The subjects of this study were 11 elementary school fifth-grade students. The material and media expert is a lecturer in mathematics education and information technology education, respectively. The validity test was carried out using the expert judgment method. Eleven fifth-grade elementary school students assessed the practicality and effectiveness tests to determine the responses and results in fractional mathematics after using the developed mobile learning. This study uses both quantitative and qualitative data, which were collected using questionnaires and learning outcomes tests. The validity of mobile learning produces an average of 3.59 or is in the interval 2.50 ≤ Rv ≤ 4.00 with valid criteria. The effectiveness of mobile learning is obtained from the pretest and posttest data. The practicality of mobile learning obtained an average of 3.82 or is in the interval 2.50 ≤ Rk ≤ 4.00 with practical criteria. The effectiveness of mobile learning shows a significance value of 0.0010 or < 0.0050, which means that there are differences in student learning outcomes before and after using mobile learning. Thus, the development of procedural and conceptual-based mobile learning on fractional material in fifth-grade elementary school can be categorized as valid, practical, and effective.
Evaluation of crack resistance of welded joints with soft interlayers
Authors: Molokov K. A. , Novikov V. V.
Published: January 2022

Introduction. Welded joints in large-sized metal structures (e.g., in the structures of ship hulls) subject to low-cycle fatigue are considered. The characteristic appearance of soft interlayers, which are significantly plastically deformed under working loads, was noted. Deformation of the metal structure with damage, especially in the form of cracks, reduces the strength and reliability of structural elements and joints. Pre-deformation negatively affects plasticity; therefore, much depends on the residual plasticity of the cracking material. At the same time, with a decrease in residual plasticity, such an important reliability indicator as the resistance of the material to crack propagation — the fracture toughness – decreases. The paper is devoted to the development of a model that includes analytical dependences for assessing the crack resistance of metal structures and their welded joints with soft interlayers according to the crack resistance limit for all crack sizes.

Materials and Methods. The theory and methods of linear mechanics of materials destruction, structural-mechanical approach are used. The calculation results were analyzed and compared to the experimental data and other analytical solutions. The numerical experiment was performed for the ferrite-perlite steel grades of 10, 50, 22K, St3sp, etc., widely used in industry, as well as for alloy steels hardened to medium and high strength of 30KhGSA, 37KhN3A, etc. Results. Analytical dependences are obtained for calculating the relative crack resistance limit according to three main known mechanical characteristics of the state of the material of the soft interlayer of the welded joint.

Discussion and Conclusions. The results obtained can be used to assess the crack resistance of pre-deformed structural elements and welded joints (including those with soft interlayers) operating under a transverse load. The results of experimental data and analytical calculations are shown in dimensionless form, which enables to obtain invariant results with respect to the fracture toughness limit.
