Energy efficiency in materials testing by reactive power – part 1: power recirculating method in wear testing
Authors: Findeisen Dietmar , Schröpfer Dirk 
Published: December 2024

Abstract
Reactive power is related to the type of power that does not consume energy but stores it. In the design of test machines, the utilization of this physical phenomenon would be very beneficial. Reactive power allows for the combination of power amplification with energy savings, making it an ideal principle for conducting long-term tests that involve high loads and prolonged energy consumption. This concept is illustrated in this work focusing test machines used in rotary testing procedures. Drive element pairs, which serve as component test objects, are primarily exposed to wear stress. These stressed element pairs are consequently integral parts of a tribological system. The underlying principles of power amplification and power feedback are explained from the perspectives of drive technology, systematic design, methodical design, and mechatronics.

Abstract
The current study investigates the presence 222Rn in tap water, natural spring water, and well water from various locations in Er-Rachidia, Morocco, to assess the potential radiological risks posed to the local community. Radon, a radioactive gas produced by the decay of uranium and thorium in rocks and soil, poses significant radiation hazards. Using a Nuclear Track Detector (LR-115), researchers investigated the presence of radon in water from wells, dams, and rivers. The highest radon concentrations are found in well water, with an average of 1.92 Bq/L. The concentration of river water is the lowest, coming in at 0.53 Bq/L, while the average concentration of dam water is 0.84 Bq/L. On average, the annual effective dosage for well water is 4.57 ms per year. The water dosages from dams range from 1.74 to 2.44 μSv/y, with 1.98 being the average. River water ranges from 0.51 to 1.69 mSv/y, averaging 1.24 µSv/y. The excess lifetime cancer risk varies significantly across water sources: 1.27 × 10−3 to 1.84 × 10−3 (average 1.60 × 10−3) for well water, 0.61 × 10−3 to 0.85 × 10−3 (average 0.69 × 10−3) for dam water, and 0.18 × 10−3 to 0.59 × 10−3 (average 0.43 × 10−3) for river water. The results dispel fears of significant radioactive dangers to the locals by suggesting that the measured radon concentrations are within the limits set by international organizations.
Gas–liquid upflow packed bed reactors: a comprehensive review focused on heat transport
Authors: Taulamet María J. , Martínez Osvaldo M. , Barreto Guillermo F. , Mariani Néstor J. 
Published: December 2024

Abstract
A review of the available information about the packed bed reactors with cocurrent upflow of gas and liquid (UFRs), particularly focused on heat transfer with an external medium through the container wall, was undertaken in this contribution. The typical use of such reactors is summarized as well as some novel applications. A brief discussion about fluid-dynamics is also made due to its strong effect on the transport processes. Experimental setup, available data, and literature correlations of heat transfer parameters are thoroughly reviewed. From a critical analysis of the experimental data, a refined database has been built, which allows comparing the performance of the existing correlations for the two parameters of the extensively employed two-dimensional pseudo-homogeneous plug flow model (i.e., effective radial thermal conductivity and wall heat transfer coefficient). In addition, new correlations for these parameters have been developed, which allow improving the actual predictive capabilities. Finally, the global heat transfer between the bed and the wall was comparatively analyzed for upflow (UFRs) and downflow (TBRs) gas–liquid packed bed reactors.

Published: December 2024

Nossa pesquisa investigou a frequência, a diversidade e a progressão no uso de terminologia metalinguística, em livros de alfabetização. Examinamos os enunciados dos exercícios propostos aos aprendizes, em seis livros de três línguas (português, francês e catalão). Analisamos o uso de nomes para unidades linguísticas orais e escritas, categorizadas em diferentes tipos: sublexical (“vogal”, “sílaba”, “letra” etc.), lexical (“nome”, “palavra”), frasal (“frase”, “questão”), textual (“texto”, “história”, “título”) e outras (“símbolo”, “diagrama”). Observou-se que os termos sublexicais eram os mais usados, embora ao longo dos livros os termos textuais crescessem em frequência. Ao discutirmos as relações entre essas evidências e concepções sobre o aprendizado da leitura e da escrita, sugerimos que o uso daqueles termos, nos livros, não implica que as crianças compreendam os conceitos a que eles se referem.Palavras-chave: psicolinguística, livros didáticos, alfabetização. Metalinguistic terminology in alphabetization books used in Brazil, France and CataloniaAbstractThe present study explored the frequency, diversity and advance in the use of metalinguistic terminology in alphabetization books. We focused on procedural instructions for the apprentices in the proposed exercises on six textbooks from three languages (Portuguese, Catalan and French). We analyze the use of the names for the oral and written linguistic units which were categorized in different types: sublexical (“vowel”, “syllable”, “letter” etc.), lexical (“name”, “word”), phrasal (“phrase”, “question”), textual (“text”, “story”, “title”) and others (“symbol”, “diagram”). We observed that sublexical terms were the most used, but throughout the school year the rates of textual terms tended to increase in frequency. Discussing the relationship between these evidences and theoretical conceptions about learning to read and to write, we suggest that the use of terms in textbooks does not imply children’s understanding of the concepts those terms refer to.Keywords: psycholinguistics, basal readers, reading instruction.

Para a criança aprender a escrever de forma adequada terá que compreender, e não só memorizar, muitas das regras ortográficas de nossa língua. Buscando compreender o efeito da explicitação do conhecimento em níveis distintos para a apropriação da ortografia, esse estudo teve como objetivo relacionar o domínio ortográfico com o desempenho de crianças de terceiro e quinto ano em tarefas de habilidades metafonológicas e o nível de explicitação sobre as restrições regulares da norma ortográfica. Os resultados apontaram que quanto maior a capacidade de manipulação sobre as regras estudadas melhor o desempenho ortográfico. Tal desempenho também está relacionado ao aumento da escolaridade e ao domínio das habilidades metafonológicas. Concluímos, desse modo, que o ensino da ortografia deve levar o aprendiz a refletir de forma explícita sobre as regras estudadas.Palavras-chave: Ortografia, Consciência Fonológica, Norma ortográfica.

Da pólis ao Mediterrâneo
Authors: Moerbeck Guilherme 
Published: December 2024

Este texto pretende dar conta de uma questão central: em que níveis teóricos e respondendo a quais problemas, a História do Mediterrâneo Antigo se estabeleceu como um movimento intelectual, talvez mesmo um paradigma aos pesquisadores da antiguidade? Hipóteses heurísticas, mudanças sociais do mundo contemporâneo e pesquisas empíricas remodelam os domínios da História. Trata-se de movimentos “tectônicos”, lentos, mas profundos, que consolidam novos olhares e métodos que dão nova forma aos estudos de determinadas temporalidades. Para interpretar esses movimentos estruturais que deram forma às leituras mediterrânicas, recorrer-se-á a um tipo uma reflexão que transitará entre a epistemologia da história e leituras de origem arqueológica e histórica.

Authors: Kaur Harleen , Kaur Gurpreet , Kaur Navneet 
Published: December 2024

: The success of dental implant is based on direct contact between supporting alveolar bone and implants. Traditional surgical approaches to manage soft tissue discrepancies have shown initial good results, but virtually there is a significant reduction of tissue that may occur as soft tissue matures often. Minimally invasive procedures such as dermal fillers may be suitable alternative to correct soft tissue discrepancies. : The aim of our study is to clinically evaluate efficacy of hyaluronic acid dermal filler for soft tissue augmentation around dental implants in Seibert’s class I/II ridges with minimal soft tissue deficiency.: A total of 5 (1 female and 4 males) systematically healthy implant patients with single/ partially edentulous site in maxillary/mandibular region with minimal soft tissue deficiency were randomly selected and treated for soft tissue augmentation with 1% hyaluronic dermal filler. All the patients were evaluated for soft tissue parameters of soft tissue thickness, keratinized tissue width, papillary soft tissue horizontal width, papillary recession depth and papillary index score at baseline, 45th and 90th day after soft tissue augmentation. At 45 day width of soft tissue (Mesial Papilla, Mid buccal point and distal papilla), Width of keratinized mucosa, soft tissue horizontal width (buccal and lingual point), papillary recession depth, showed statistically significant difference but no significant difference seen between 45 days and 90 days. Injecting hyaluronic acid helped in improving various parameters but for a short period of time only.

Unraveling the yield heterosis formation of the Chinses cabbage hybrid by the comparative transcriptomic analysis and LHCB1 gene function analysis
Authors: Wang Ruihua , Han Min , Han Taili , Li Yuanyuan 
Published: December 2024

Abstract

Changes in gene expression in hybrids are closely related to the heterosis formation. Currently, few reports have been reported on key genes that promote the yield advantage formation in Chinese cabbage hybrid. In the present study, RNA sequencing and virus-induced gene silencing were performed to elucidate the underlying mechanisms of yield advantage formation in Chinese cabbage hybrid (weichunbai No.3). In total, 3652 and 2768 genes were differentially expressed genes between the Chinese cabbage hybrid and its parents in the rosette and the mature stages, respectively. These differentially expressed genes among the hybrid and its parents showed diverse expression patterns, and the overwhelming majority of differentially expressed genes were additively expressed genes. A vital additively expressed gene related to the plant weight, BraA09g035160.3C, was found by the weighted gene co-expression network analysis. Through virus-induced gene silencing technology, the expression level of BraA09g035160.3C in the hybrid was dramatically decreased, which resulted in slowing the hybrid growth, indicating that this gene could be related to the formation of hybrid yield advantage. These results will provide an important reference for in-depth research on the molecular mechanism underlying the yield advantage formation of Chinese cabbage hybrid.

Abstract

The clinical effect of surgery timing in older patients with intertrochanteric fractures (IFs) is controversial. Our objective was to assess the association between surgery timing and in-hospital mortality and postoperative complications in these patients. In our study, 228,725 patients accepted internal fixation surgery for IFs were obtained from the 2002 to 2014 Nationwide inpatient sample (NIS) database. They were categorized into 3 subgroups according to the time of admission to surgery: early, shorter delays, and longer delays. The prevalence of internal fixation surgery in IFs patients significantly increased over time. Delays in surgery were associated with longer LOS, extra hospital charges, and higher risk of postoperative complications. Rates of in-hospital death were 2.110% and 4.214%, respectively in two delay groups. After adjustment, shorter delays was not associated with in-hospital death (OR: 1.024, CI: 0.953, 1.088;P = 0.520), longer delays was obviously associated with an increased risk of death during hospitalization (OR: 1.547, CI: 1.410, 1.696;P<0.001). Prolonged waiting time for surgery significantly increased the risk of developing adverse events. Therefore, reasonable preoperative optimization and strive for early surgery are necessary.
