Effect of geographic isolation and temporal patterns on use of wildmeat and fishery resources in Eastern Amazonia, Brazil
Authors: Goncalves Andrey Felipe Gomes , Pezzuti Juarez Carlos Brito
Published: December 2023

The advance of urbanization, the construction of large-scale projects, and the intensification of the extraction of natural resources are modifying the food consumption patterns of human populations in the Amazon. The influences of the population's economic integration and proximity to the market are crucial factors that shape various aspects of their livelihoods. We evaluated the influence of distance to the commercial center, temporal variation, and river flow on the diversity and composition of wild meat and fishes consumed in two RESEXs in Eastern Amazonia. The data came from the National Biodiversity Monitoring Program, coordinated by the Chico Mendes Institute for Biodiversity Conservation, which has been in progress since 2014. We found a significant presence of industrialized food in the diet of populations close to the urban center and a presence of fish and wild meat in the meals from populations that live farther away. The consumption of fish and hunting animals is decreasing over the years without an increase in the consumption of industrialized food, which may represent a case of food insecurity for these populations. The consumption of fishes presented seasonal variations, guided by the river flow. Fishing and hunting play a significant role in the sustenance of these populations, but their decline over time may exhibit a worrisome pattern.
A influência da analogia dos jogos no método de investigação gramatical de Wittgenstein
Authors: Soares Thauan Santos , Donat Mirian
Published: December 2023

O objetivo deste artigo é investigar a origem da analogia dos jogos no pensamento de Wittgenstein e a sua influência no desenvolvimento de seu método de investigação gramatical, principalmente em sua obra Investigações filosóficas (2022). Consideramos as noções de regras, seguir regras e gramática como partes essenciais do aspecto normativo da linguagem, e a analogia com os jogos - especialmente na forma de jogos de linguagem - é uma poderosa ferramenta pedagógica com o objetivo de esclarecer o funcionamento de nossa linguagem. Inicialmente, exploraremos como a filosofia de Wittgenstein incorpora a imagem do jogo e a utiliza como uma ferramenta para esclarecer os problemas filosóficos e compreender a natureza da linguagem e da significação. Em um segundo momento, buscaremos compreender se seguir uma regra é uma prática necessariamente social. Por fim, abordaremos qual é o papel que os jogos de linguagem desempenham no interior do método de Wittgenstein. A partir da abordagem desses três pontos, pretendemos mostrar a importância da analogia dos jogos em relação no esclarecimento do funcionamento de nossa linguagem, principalmente no que tange o seu caráter normativo.

Published: December 2023

Objective: To describe the trend in hepatitis-A virus (HAV)-related hospitalisations in children and analyse the association of demographic, clinical and laboratory manifestations with length of stay (LOS) of HAV infection.Method: A retrospective study was conducted in Siloam Hospitals Indonesia. Inclusion criteria were hospitalised paediatric hepatitis A patients aged 3-17 years from 2015-2021. Another viral hepatitis was excluded. Total 58 samples were divided into non-prolonged group (LOS<5 days) and prolonged group (LOS≥5 days). Demographic data, clinical manifestations and laboratory parameters were collected and analysed using SPSS. Correlations with p <0.05 were considered significant.Results: Hospitalisation rate pattern showed two peaks in 2016 and in 2019. The monocyte-to-leucocyte ratio (MLR), blood urea nitrogen (BUN), and creatinine were significantly associated with LOS in bivariate analysis. Medians of MLR and BUN were higher in the prolonged group (0.23; 17) than in the non-prolonged group (0.19; 15.98). Median of creatinine was lower in the prolonged group (0.55) than in the non-prolonged group (0.74). Multivariate analysis found that dark urine was less likely to have a prolonged LOS (OR: 0.23; 95% CI 0.06-0.91, p = 0.04).Conclusions: Dark urine was a protective factor for prolonged LOS. Independently, higher BUN and higher MLR were risk factors for prolonged LOS.

Review of Graph Neural Networks for Medical Image
Authors: Wang Jing
Published: December 2023

As deep learning continues to evolve, more and more applications are generating data from non-Euclidean domains and representing them as graphs with complex relationships and interdependencies between objects. This poses a significant challenge to deep learning algorithms. Because, due to the uniqueness of graphs, applying deep learning to ubiquitous graph data is not an easy task. To solve the problem in non-Euclidean domains, graph Neural Networks (GNNs) have emerged. A graph neural network (GNN) is a neural model that captures dependencies between graphs by passing messages between graph nodes. With the continuous development of medical image technology, medical image diagnosis plays a crucial role in clinical practice. However, in practice, medical images are often affected by noise, artifacts, and other interfering factors, which may lead to inaccurate and unstable diagnostic results. Therefore, image-denoising techniques become especially critical in medical image processing. Therefore, researchers have proposed innovative methods based on graph neural networks for effective noise removal, preserving the key features of the image and improving the quality and usability of medical images. This paper reviews the research progress of graph neural networks in the field of medical image denoising. It also summarises the problems and challenges of current research and looks at the future direction of medical image-denoising research.
Experimental Analysis of the Behavior of Automotive Twin-Tube Dampers
Degraded by Loss of Oil and Pressure
Authors: Zwosta Tobias , Kubenz Jan , Prokop Günther
Published: December 2023

Automotive dampers are essential vehicle components regarding vehicle dynamics by
keeping the road contact and reducing wheel load fluctuations. So damper
degradation could not only significantly influence driving comfort but also the
dynamics and therefore driving safety. The aim of this study is to expand
knowledge about the behavior of passive automotive twin-tube dampers degraded by
loss of oil and pressure. This serves to improve the understanding of inner
processes of the damper and modeling the behavior of degraded dampers. To
analyze the damper behavior, an intact damper has been modified and validated to
allow adjusting the oil and pressure level. Using a dynamic hydraulic damper
test rig a preconditioning routine for degraded dampers is developed. With this
routine, a wide measurement program at various amplitudes, frequencies,
oscillations, and damper configurations is carried out and the obtained results
are discussed. The conducted measurement program did not cover small amplitudes
(<8.4 mm) and high frequencies (>19 Hz).

The results show that the loss of oil or pressure leads to complex dependencies
on all varied parameters such as amplitude, frequency, number of oscillations,
and waiting time between two measurements. While the absence of pressure only
leads to small performance reductions, especially the loss of oil leads to
significant deterioration of the damper performance. Already at a level of 90%
of the original oil volume, the examined damper loses up to 30% of its
performance under disadvantageous operating conditions. Furthermore, the loss of
oil can make a damper almost useless when 40% of the oil is still present.

Possible inhibitory effects of hoslundal, hoslundin and hoslunddiol on human lactate dehydrogenases: a bioinformatics proof
Authors: BİLGİN Yagmur , YALNIZOĞLU Yasir , ÇAVAŞ Levent
Published: December 2023

The development of anti-malarial drugs is of great importance due to the detrimental effects of this disease all around the world. In recent years, bioinformatics tools provide considerable contributions to develop new small molecules which have important bioactivities against many bio-targets. However, biases in the methodologies or aims of the studies in which in silico tools are used may reveal problematic cases. Hoslundal, hoslundin, and hoslunddiol were proposed by Shadrack et al. (2016) to inhibit Plasmodium falciparum lactate dehydrogenase (Pf-LDH) to fight malaria. But these molecules may have potential to inhibit mammalian LDHs. To investigate whether these molecules have inhibitions on mammalian LDHs or not, we studied a comprehensive and comparative molecular docking studies as described in the present paper. According to the results, the vina scores of hoslundal without NADH for Pf-LDH, HM-LDH, HH-LDH were found as -7.5, -7.6 and -8.2 kJ/mol, respectively. Moreover, multiple sequence alignment analysis reveals high similarities among sequences. In the light of molecular studies, hoslundal were found to be connected to Pf-LDH, HM-LDH, HH-LDH (31, 26, 34), (2, -7, 154), (11, 41, 54), respectively. In conclusion, novel small molecules which are developed via in silico tools could show excellent activities against bio-targets of the pathogenic microorganisms. However, it should not be forgotten that active site of the enzymes is conserved, therefore, after a possible proposal of small molecule, its molecular docking and also Swiss-ADME studies should be necessarily carried out.

ICAO recommends that capacity and efficiency achievement programs be carried out through the Performance Based Navigation (PBN) implementation model. This research aims to obtain an overview of the optimal formula model that can be implemented into flight paths based on the RNP approach procedure for flight path efficiency and fuel efficiency. This research uses quantitative experimental methods. The results of this research are that the optimization model at minimum speed (V=210 knots) produces route effectiveness of 8% and fuel savings of 1.5% compared to the established current procedure. The conclusion is that for straight paths, route optimization is achieved by applying the maximum speed, but for circular (arc) paths, route optimization is achieved by applying the specified minimum speed.
