Authors: Schmidt Wolfram , Brandt-Wunderlich Christoph , Kamke Frank , Schwerdt Christopher , Kaminsky Jörg , Behrens Peter , Schmitz Klaus-Peter , Grabow Niels 
Published: December 2024

Abstract
Pulsatile fatigue testing is a basic requirement for arterial stents, however, there are several opportunities to setup and conduct the testing. The recently published standard guide ASTM F2477:2023 provides specific guidance, in particular includes the pressure controlled test method applying an outer hydraulic pressure to the test samples. The current work describes this approach, and demonstrates that the technical requirements can be met successfully. In addition, some inherent advantages are discussed, e.g. accuracy of pressure loading, absence of stent migration and potential high test frequencies.
Do we need new standards in dental implant testing?
Authors: Schneider Simon Matthias , Engleder Thomas , Schneider Robert , Haeger Andreas 
Published: December 2024

Abstract
The ISO 14801 standard test is repeatedly criticized for not reflecting the actual conditions and loads realistically enough to which dental implants are exposed (e. g. during chewing). The aim of this paper is to provide a brief review of the test parameters of the ISO standard and to compare them critically with the parameters that prevail in vivo. The research revealed significant simplifications of the test conditions, wich can partly be justified with better reproducibility and comparability. Nevertheless, the realization remains that the test deviates considerably from real physiological loading conditions and should be adapted accordingly or supplemented by further tests.

Published: December 2024

Abstract
Heart rate variability (HRV) is an important marker in various cardiovascular and non-cardiovascular conditions. This study aimed to evaluate the effectiveness of three linear models (Logistic Regression, Ridge Regression, Support Vector Machine) in distinguishing between healthy individuals and those with valvular heart diseases (VHD) using time domain and frequency domain HRV indices derived from electrocardiographic (ECG) signals. We analyzed 59 recordings taken from two public datasets containing electrocardiographic, seismocardiographic, and gyrocardiographic signals from “Mechanocardiograms with ECG reference” and “An Open-access Database for the Evaluation of Cardio-mechanical Signals from Patients with Valvular Heart Diseases” that contain 29 and 30 recordings, respectively. HRV analysis included time and frequency domain indices and the linear models were evaluated using 5-fold stratified cross-validation. The highest sensitivity, PPV, accuracy and F1 score were observed for Logistic Regression (0.8810, 0.8819, 0.8814, 0.8812), followed by Ridge Regression (0.8805, 0.8858, 0.8814, 0.8808), and the lowest were observed for linear SVM (0.8310, 0.8318, 0.8305, 0.8305). The results showed that it is possible to distinguish healthy volunteers and patients with linear classifiers and time domain and frequency domain HRV indices obtained from ECG signals with decent performance.

Published: December 2024

Abstract
These days, many jobs like working in an office include sitting in chairs for a long time which could lead to work-related disorders such as musculoskeletal issues. Inappropriate postures can cause muscle fatigue in certain regions, resulting in pain and discomfort. Analysis of different types of postures to indicate discomfort could help us choose an optimal posture. This study evaluates five different sitting postures in an office chair for comfort and discomfort. Each posture was held for 18 minutes with a two minute break between postures. Six participants with an equal number of male and female subjects were chosen. The sitting posture correlates with the distribution of the weight on the seat, which can be measured by pressure sensors. The pressure distribution was obtained using a custom-built pressure mat and the maximum pressure were evaluated. The McGill Questionnaire construct was used to find subjective discomfort at each minute. There was no difference in results for both sexes. Overall, leaning to one side was felt more comfortable while sitting with a curved back caused the highest discomfort.
Experimental and Simulative Analysis of Magnetic Nanoparticle Accumulation Using Various Halbach Arrays
Authors: Thalmayer Angelika S. , Götz Kilian , Lübke Maximilian , Fischer Georg 
Published: December 2024

Abstract
One of the major challenges in using magnetic nanoparticles in biomedical applications is still the accurate steering and trapping of these particles at a desired location, like at a tumor. Halbach arrays are well-established here as they generate the strongest magnetic force. However, these arrays are mechanically unstable, and thus, their potential to attract magnetic particles is often investigated fully numerically. Hence, this paper provides instructions on how to easily produce Halbach arrays using permanent magnets and metal glue. In total, three Halbach arrays of five, seven, and nine magnets were produced and analyzed regarding their potential for capturing magnetic particles in a background flow, numerically using COMSOL Multiphysics and in measurements. Furthermore, the Halbach arrays are compared with two other array configurations with all magnetizations in the same directions and alternating once. Overall, the simulation results were in good agreement with the measurement results. The amount of captured particles was significantly higher in measurements for the Halbach arrays with 8.2 %, compared to the array with alternating magnetization direction with 6.6% captured particles. Therefore, using Halbach arrays to capture or steer magnetic nanoparticles in a background flow is strongly recommended.

Published: December 2024

Abstract
Electrical Impedance Tomography is used to image the cross-sectional conductivity of an object. It is clinically used for high-frame-rate imaging of lung ventilation. Most current systems use very limited current injection waveforms and patterns. We have developed a flexible system for researching alternatives. This paper covers our voltage conditioning module’s design and characterisation. The device was shown to work up to the desired 10 MHz. The responses were uniform with minor gain mismatch between all channels after manufacturing variations. The low-frequency (<1 MHz) crosstalk is on the order -55 dB, and the worst cases around 8 MHz are around -35 dB.
Theoretical analysis of piezoceramic ultrasonic energy harvester applicable in biomedical implanted devices
Authors: Dezhara Aboozar , Grasso Alfio Dario , Ballo Andrea 
Published: December 2024

Abstract
In this article, we theoretically analyze the one-dimensional model of a piezoceramic energy harvester that uses piezoelectric transduction in the 3-3 mode to convert ultrasonic pressure waves into electrical energy. Our approach to this problem is new because we did not use impedance approach which is a common method in many other articles. Nonetheless, our solution accounts for loss of acoustic environment. Our goal here is to extract maximum power from output load. Based on our simulations, the frequencies that the acoustic strength peaks are as same as frequencies that the pressure at receiver side peaks, and between these frequencies, the resonance occurs at a frequency that the pressure at the receiver side has a maximum peak. We propose two boundary conditions for radiating acoustical waves. In this article for a square shape transducer with a thickness of 2.1 mm and length of 1.46 cm, the resistive output load gave the most power, in which its value for free-fixed and free-free boundary conditions are 13.75 W and 17.37 W respectively, and at output resistances of 8.51 Ω and 13.11 Ω respectively. The required acoustic strengths to produce these powers for free-fixed and free-free boundary conditions are

Published: December 2024

Abstract

Objective
To investigate the relationship between the expression levels of serum forkhead box protein M1(FOXM1) and insulin-like growth factor 2 (IGF2) mRNA in patients with acute respiratory distress syndrome (ARDS) condition and prognosis.

Methods
Ninety patients with ARDS admitted to our hospital were regarded as the ARDS group, according to the prognosis, they were grouped into death group (n = 64) and survival group (n = 126); the control group consisted of 190 healthy individuals.

Results
Compared with the control group, the level of serum FOXM1 mRNA in ARDS group was obviously lower, and the level of IGF2 mRNA was higher. The serum IGF2 mRNA, serum creatinine, inhaled oxygen concentration (FiO2), and mechanical ventilation time in the death group were higher than those in the control group, and the arterial oxygen partial pressure (PaO2), FOXM1 mRNA, and oxygenation index (PaO2/FiO2) were lower than those in control group. Logistic regression analysis indicated that FOXM1, IGF2, and PaO2/FiO2 were significant factors influencing the prognosis and mortality in ARDS patients. Correlation analysis showed that there was a negative correlation between serum FOXM1 and IGF2 mRNA levels in patients with ARDS.

Conclusion
Serum FOXM1 and IGF2 mRNA in patients with ARDS are correlated with the severity and prognosis of ARDS.
Entre palavra e imagem – elementos para pensar o potencial de ficcionalização da prática pedagógica
Authors: Souza da Silva Tatielle Rita 
Published: December 2024

O tema que buscamos percorrer neste trabalho concebe a linguagem não só como elemento que nos permite representar o mundo como também criá-lo. Desse modo, procuramos fazer da atuação em uma escola da rede pública municipal situada em uma zona periférica de Porto Alegre o campo empírico interrogante que nos instiga e nos convoca a assumir um compromisso com o lugar da experiência docente. Interessa-nos pensar o espaço escolar como um espaço em potencial de criação. Para cumprir este fim, a metodologia escolhida nos conduz a um olhar que se desloca como o de um voyeur, recolhendo fotografias de cenários e personagens, tramas e memórias, autorizando estes fractais do vivido a refazer os traços da existência via enunciação simbólica. É desde este lugar de estrangeiridade e estranhamento do banal e do cotidiano que vimos pensando o papel da linguagem não como monologia, imposição de sentido, mas como abertura – capaz de conjugar vida, arte e ficcionalização.

Published: December 2024

Croatia has a highly indented coastline, favourable ecological conditions, proximity to the markets, and potential for further mariculture development. This research aims to determine the status of Croatian mariculture considering: distribution of fish and bivalve farms, total mariculture area, buffer zone, Internal Waters Utilization, nominal intensity, number of registered operators, and employees in the industry. The spatial database was created using manual vectorization from recent (2022/2024) Google Earth satellite imagery. The results show that marine farms in Croatia occupy 0.056% of the area of internal marine waters. Out of this, 53 % of the surface is dedicated to bivalve and 47% to fish farming. Croatia’s total nominal intensity is 3.3 t/km of coastline in 2022. Farms are located in all coastal counties, with the largest occupied area in Zadar County (38.1%) and Dubrovnik-Neretva County (37.5%). Most of the national fish farming area is located in Zadar County (71%), while the largest area of bivalve farming (68%) is found in Dubrovnik-Neretva County. In Primorje-Gorski Kotar County, despite having the largest area of internal marine waters, only 4.3% of the total mariculture area is present. The analysis indicates that mariculture currently occurs in a tiny portion of internal marine waters and has generally lower nominal intensity than other Mediterranean countries. Although mariculture is present in all coastal counties, the distribution and productivity of farms is uneven. For future development, we suggest focusing on optimizing current production capacities and exploring innovative aquaculture practices to enhance sustainability and economic viability.

Tratamento judicial do superendividamento: o plano compulsório e a postura do fornecedor
Authors: Alessandra Machado Flávia 
Published: December 2024

Entende-se por superendividamento a impossibilidade global de o devedor pessoa física, consumidor, leigo e de boa-fé, pagar todas as suas dívidas atuais e futuras de consumo, sem comprometer seu mínimo existencial. Diante desse fenômeno da sociedade de consumo, surgiu a Lei 14.181/2021, que alterou o Código de Defesa do Consumidor e regulamentou os deveres da boa-fé na concessão de crédito pelo fornecedor e seus intermediários na venda a prazo. Na esfera judicial, como forma de tratamento do superendividamento, a nova Lei também prevê o plano compulsório de renegociação de dívidas, que visa restabelecer a possibilidade de o consumidor voltar a viver sem o prejuízo do seu mínimo existencial. Neste contexto, através do método dedutivo e pesquisa bibliográfica, buscar-se-á responder ao seguinte: até que ponto a “nova” postura do fornecedor, inserida na lei consumerista, contribui para a diminuição do número de ações de superendividamento no Poder Judiciário e quais as medidas necessárias para uma maior efetividade da proposta? Para tanto, adota-se o método de abordagem dedutivo, partindo das modificações trazidas pela Lei 14.181/2021, para, ao final, se refletir sobre as mudanças necessárias para uma maior efetividade na prevenção, através do comportamento do fornecedor de produtos ou serviços. Por fim, pode-se concluir que os fornecedores de crédito devem adotar condutas compatíveis com a realização sustentável do contrato, adequando a oferta de acordo com a capacidade econômica do consumidor, promovendo assim uma maior efetividade do princípio do crédito responsável.

Published: December 2024

A vacinação é uma das intervenções de maior custo-efetividade e de considerável impacto na ocorrência de doenças. Logo, é necessário o monitoramento da cobertura vacinal e o perfil vacinal das crianças imunizadas. Objetivou-se conhecer o perfil epidemiológico da cobertura vacinal de crianças de 0 a 12 meses com esquema completo no município de Palmas-TO nos anos de 2020 e 2021. Trata-se de um estudo epidemiológico descritivo, retrospectivo, de abordagem quantitativa que utilizou fonte de dados secundários, provenientes do sistema BI-eSUS e base de dados do Departamento de Informática do SUS. Foi avaliada a cobertura vacinal dos imunobiológicos estabelecidos no primeiro ano de vida e as variáveis selecionadas foram: sexo do familiar, faixa etária, etnia/cor, ocupação e nível de escolaridade do responsável, localização urbana ou rural e renda familiar. Como resultado, a vacina BCG foi a única que apresentou cobertura vacinal superior a 95%, já os demais imunobiológicos não alcançaram a cobertura vacinal preconizada. Referente ao perfil demográfico, destaca-se o ensino médio completo, a renda familiar entre um e dois salários mínimos, sexo feminino e a faixa etária 30 a 39 anos. Logo, melhores padrões sociodemográficos podem contribuir positivamente na adesão à vacinação.
