Abstract
This report unveils the outcomes of measurements of 222Rn exhalation rates, effective 226Ra content, and the annual effective dose for rocks and soil collected in the vicinity and far from the seismically active Kopili Fault Zone, India. LR-115 (II) nuclear track detector has been used to investigate radiation exposure in the seismically active fault zone and gneissic complex of the Shillong Plateau, which have significant geological characteristics and frequently produce earthquakes. In this study, 222Rn mass exhalation rates for granite, gneiss, and soil samples collected near and far from the fault were calculated to be in the ranges of 73.2–83.0, 11.0–14.8, 21.1–70.7 and 34.3–65.5, 6.4–9.9, 19.1–28.9 mBq kg−1 h−1, respectively. Surface exhalation rates of 222Rn for granite, gneiss, and soil samples collected near and far from the fault varied between 2428.8–2751.7, 365.6–491.9, 698.3–2345.9, and 1138.6–2172.7, 211.9–328.2, 634.9–960.0 mBq m−2 h−1, respectively. The 226Ra contents of granite, gneiss, and soil collected in similar distributions were found to vary from 9.76–11.06, 1.47–1.98, 2.8–9.4, and 4.58–8.74, 0.85–1.32, 2.6–3.6 Bq kg−1, respectively. The annual effective doses attributed to 222Rn inhalation from exposure to the samples were calculated to be in the ranges of 176.3–199.8, 26.5–35.7, 50.7–170.3 and 82.7–157.7, 15.4–23.8, 46.1–69.7 μSv y−1, respectively, for granite, gneiss, and soil. The lifetime fatality-risks have also been analysed in this study. The samples that were collected in close proximity to the fault showed higher values than those that were collected farther away. However, the results reveal that the measured values are within the globally recognised permissible range.

Abstract
The production method of no-carrier added Lutetium-177 (177Lu) was developed from a neutron-activated natural ytterbium (Yb) using column chromatography separation method. Dowex W50 X8 resin and a combination of alpha-hydroxyisobutyric acid (α-HIBA) and hydrochloric acid (HCl) were used as column filler and eluent, respectively. HCl increased the desorption and separation between 177Lu and Yb at a concentration of 0.25 M, while the optimal α-HIBA concentration was 0.15 M, resulting in 177Lu yield of 81.19 % and low impurities (175Yb: 9.28 %, and 169Yb: 2.09 %). Nevertheless, further study using an enriched 176Yb target is essential to significantly increase the specific activity of 177Lu.

Published: February 2024

Abstract
Excitation functions for the formation of the radionuclides 51Cr, 52Mn and 54Mn via deuteron-induced activation of natural iron were measured up to deuteron energies of 35 MeV. The available experimental databases of the reaction products 51Cr, 52Mn and 54Mn were extended and compared with the nuclear model calculations using the TALYS code. The model calculations reproduce our measured data after a careful choice of the input model parameters. Some information obtained on competition between the emission of multinucleons and a bound α-particle.
Estudo sobre a Propagação da Cultura da Medicina Tradicional Chinesa no Brasil
Authors: Wang Ruotong , Filho Floriano 
Published: February 2024

Resumo
Diferentes sociedades e culturas têm vários conhecimentos sobre as causas das doenças. Normalmente, as pessoas interpretam sua constituição corporal e respondem a fenômenos clínicos com base em conceitos, símbolos e protocolos de diagnóstico que acumularam e internalizaram por meio de suas experiências sociais e culturais. As representações sociais da saúde e da doença estão associadas a percepções da vida e da sociedade em diferentes culturas, o que poderia explicar a reação da sociedade brasileira ao novo conceito de tratamento proporcionado pela cultura da Medicina Tradicional Chinesa (MTC). A globalização tem aprofundado o grau de trocas culturais entre países e novos hábitos chineses ganharam crescente influência no Brasil. Após décadas de assimilação e adoção, a MTC no Brasil evoluiu para um estágio, a nível técnico e cultural, relativamente maduro.

Published: February 2024

Abstract

Objectives
We aimed to investigate the lymphocyte subsets and monocytes by flow cytometry and the correlations between their HLA-DR expressions and inflammatory markers in patients with COVID-19.

Methods
The study included 49 patients with COVID-19 and 42 healthy controls. Blood samples were taken into EDTA tubes. WBC counts were analyzed by the Sysmex/XN-1000i device, and lymphocyte subsets and monocytes were analyzed by flow cytometry. The percentage of HLA-DR expression on cells and median fluorescence intensity (MFI) values were recorded to detect activation. Lymphocyte counts were calculated using the dual-platform method. Correlations between antigen expression and ferritin, CRP, and D-dimer levels were analyzed.

Results
The patient group had lower WBC and lymphocyte counts but significantly higher monocyte counts and neutrophil/lymphocyte ratios compared to controls (p=0.009, p=0.045, respectively). The patient group had significantly lower T lymphocyte counts (p=0.008). B lymphocyte counts and percentages were lower (p<0.001, p=0.004) in the patient group. There was no significant difference between the two groups in terms of NK cells. T helper and T cytotoxic lymphocyte counts were significantly lower, but there was no change in CD4/CD8 ratios. The percentage of HLA-DR expression on T lymphocytes, HLA-DR MFI values of T cytotoxic cells, and HLA-DR MFI values of CD16+ monocytes were significantly increased in the patient group (p=0.001, p=0.004, p<0.001, respectively). CRP was positively correlated with HLA-DR expression on T lymphocytes (r=0.501, p<0.001).

Conclusions
HLA-DR MFI values may be an important marker for demonstrating the function of both T cytotoxic cells and CD16+ monocytes in COVID-19.

Authors: Chen Chenlin , Jiang Yuting , Zhang Haosu , Dong Liangchen , Zhang Zitong 
Published: February 2024

Abstract
A double-wall cooling configuration including impingement holes and film holes with conformal pins is studied by CFD numerical simulation in this paper. The influences of three different injection directions of film holes at six blowing ratios ranging from 0.4 to 2.5 on conjugate heat transfer characteristic are investigated. Impingement-only arrangements with corresponding pin directions are adopted to illustrate the film cooling gains and the impingement cooling contribution. The results indicate that the effect of different pin directions on overall cooling effectiveness is non-significant. At low blowing ratio, the forward injection arrangement has higher overall cooling effectiveness since greater gain of film cooling, and is transcended by reverse injection arrangement as coolant supplement increases. Moreover, although the cooling effectiveness for normal injection case is the lowest within the whole range of mass flow rate, it possesses the most uniform distribution of cooling effectiveness in downstream region at high blowing ratio.

AbstractThis special issue focuses on the theoretical and empirical underpinnings of truth-marking. The names that have been used to refer to this phenomenon include, among others,counter-assertive focus,polar(ity) focus,verum focus,emphatic polarityor simplyverum. This terminological variety is suggestive of the wide range of ideas and conceptions that characterizes this research field. This collection aims to get closer to the core of what truly constitutes verum. We want to expand the empirical base and determine the common and diverging properties of truth-marking in the languages of the world. The objective is to set a theoretical and empirical baseline for future research on verum and related phenomena.

Published: February 2024

Abstract
In this paper, we study traveling wavefronts in an anomalous diffusion predator–prey model with the modified Leslie–Gower and Holling-type II schemes. We perform a traveling wave analysis to show that the model has heteroclinic trajectories connecting two steady state solutions of the resulting system of fractional partial differential equations and corresponding to traveling wavefronts. This also includes numerical results to show the existence of traveling wavefronts. Furthermore, we obtain the numerical time-dependent solutions in order to show the evolution of wavefronts. We find that wavefronts exist that travel faster in the anomalous subdiffusive regime than in the normal diffusive one. Our results emphasize that the main properties of traveling waves and invasions are altered by anomalous subdiffusion in this model.

Abstract
In the present work, the nitrogen doped carbon nanotubes (NCNTs) were prepared over various transition metal loaded mesoporous SBA-15 catalysts by the CVD method for supercapacitor application. Mesoporous Siliceous SBA-15 support and transition metals (Cr, Fe, Co, Ni and Cu) loaded SBA-15 (M/SBA-15) catalysts were prepared through hydrothermal and wet impregnation process, respectively. The catalytic performance of all the prepared catalysts were evaluated by synthesizing NCNTs by CVD at 800 °C using triethylamine as the precursor. The NCNTs produced over Ni/SBA-15 have an outstanding specific capacitance of 263 F g−1 at 0.5 A g−1 in 1.0 M H2SO4 aqueous solution according to the electrochemical investigations because of its increased nitrogen content of 3.2 at.%. Furthermore, a two-electrode based symmetric device was construct and tested. The fabricated device showed the specific capacitance of 113 F g−1 at 0.5 A g−1 with high energy density of 10 W h Kg−1 at the power density of 333 W kg−1. The NCNT showed 96 % of capacitance retention even after 1000 cycles. The synergism of high nitrogen content and bamboo-like graphitized structure resulted in excellent specific capacitance, better cycle life and rate performance of the prepared NCNTs as supercapacitor electrode.

Abstract
In view of the problems of the current method, such as the large error, low detection efficiency, and poor analysis ability of food deterioration early warning, a spectral feature extraction algorithm of food spoilage early warning data based on machine learning and Internet of Things was proposed. Based on Internet of Things technology, collect food spoilage warning images. The k-means algorithm is used to identify the food variable mass spectrometry data, and the three-dimensional visual feature reconstruction method is devised to reconstruct the image characteristics of the food variable mass spectrum, and the spectral characteristics of the food deterioration warning data are obtained. Based on machine learning, the features of food variable mass spectrometry image are decomposed, and the gray pheromone of food variable mass spectrometry image is extracted. Under the convolutional neural network structure, the spectral features of food deterioration early warning data are vectorized. Based on the results of spectral vectorization, the spectral features of food deterioration early warning data are extracted. The experimental results show that the proposed method can effectively improve the efficiency of food deterioration detection and reduce the error of food deterioration detection for safe environment.

In order to reduce the error of automatic frequency control of transmission machinery under different disturbances, an automatic frequency control system of transmission machinery based on back-propagation (BP) neural network algorithm is designed. The gradient descent method and Newton method are combined to optimize the BP neural network. Aiming at the periodicity and trend of the actual mechanical vibration frequency time series, the first order backward difference is processed by the difference method, and the autoregressive sequence is derived to obtain the control model. The experimental results show that the system can realize the automatic control of transmission mechanical frequency with small error under different types of interference, and the control effect is ideal.
La importancia de la educación financiera para la reducción de la pobreza en Perú
Authors: Tramontana Tocto Roxana Helena 
Published: February 2024

In Peru, according to the definition of the National Institute of Statistics and Data Processing (INEI, 2023), an individual in considered to be living in poverty if their monthly income is below PEN 415. Poverty decreased considerably from 2011 to 2019. However, after the COVID-19 pandemic, it has significantly increased, to the detriment of all progress made in the previous decade. Even though social welfare programs are a good option to fight poverty, it is necessary for these programs to complement their strategy with financial literacy to improve their effectiveness. This paper evaluates the current situation and the importance of financial literacy for the reduction of poverty in Peru. This research is descriptive, non-experimental and cross-sectional. The results of several studies conducted in various countries revealed that financial literacy is significantly effective to reduce poverty. It can be concluded that, in Peru, it is necessary to conduct more finance training programs in the Ayacucho, Cajamarca, Huánuco and Pasco regions, where the incidence of poverty is above 40%. It is also advisable to evaluate the effectiveness of financial literacy training through O'Connell's five-tier approach (2009).
Working Time of the Municipal Cities’ Officials in the Grand Duchy of Lithuania in the 16th–18th centuries: The Case of Merkinė
Authors: Tubelevičiūtė Gabija 
Published: February 2024

The history of the cities of the Grand Duchy of Lithuania has in recent years attracted more and more interest in the context of Magdeburg law, city institutions, ruling elites, etc. However, to this day there has been no significant research on the working time of city officials, and certain aspects, such as the organization of work during festivals, are used as details to supplement the historical narrative. This article focuses on the working time of the municipal cities of the Grand Duchy of Lithuania in the 16th–18th centuries, using the city of Merkinė as a reference point. The study aims to find out how the working time of municipal cities was defined by normative documents, when elections and appointments of officials took place in Merkinė, how long the term of office lasted, and when the council and the court of advocatus – lay judges worked. The main part of the article is devoted to the definition of the working time (annual, monthly, weekly) of the municipal bodies of Merkinė (the council and the court of advocatus – lay judges). The work is illustrated by tables based on the data from the act books of the court of advocatus – lay judges and the council.

BACKGROUND AND OBJECTIVES
The introduction of multiplex gastrointestinal panels at our institution resulted in increased Clostridioides difficile (C. difficile) detection and stool test utilization. We aimed to reduce hospital-onset C. difficile infections (HO-CDIs), C. difficile detection, and overall stool testing by 20% within 1 year.

METHODS
We conducted a quality improvement project from 2018 to 2020 at a large children’s hospital. Interventions included development of a C. difficile testing and treatment clinical care pathway, new options for gastrointestinal panel testing with or without C. difficile (results were suppressed if not ordered), clinical decision support tool to restrict testing, and targeted prevention efforts. Outcomes included the rate of HO-CDI (primary), C. difficile detection, and overall stool testing. All measures were evaluated monthly among hospitalized children per 10 000 patient-days (PDs) using statistical process-control charts. For balancing measures, we tracked suppressed C. difficile results that were released during real-time monitoring because of concern for true infection and C. difficile-related adverse events.

RESULTS
HO-CDI decreased by 55%, from 11 to 5 per 10 000 PDs. C. difficile detection decreased by 44%, from 18 to 10 per 10 000 PDs, and overall test utilization decreased by 29%, from 99 to 70 per 10 000 PDs. The decrease in stool tests resulted in annual savings of $55 649. Only 2.3% of initially suppressed positive C. difficile results were released, and no patients had adverse events.

CONCLUSIONS
Diagnostic stewardship strategies, coupled with an evidence-based clinical care pathway, can be used to decrease C. difficile and improve overall test utilization.
Analysis of the relationship between China's direct investment in Central and Eastern Europe and trade
Authors: Song Wenxuan 
Published: February 2024

AbstractThis study aims to investigate the relationship between China's outward foreign direct investment (OFDI) in Central and Eastern European countries (CEECs) by assessing their impact on the economies of both the CEECs and China. By analyzing this connection, the paper seeks to gain insights into the economic dynamics and potential benefits derived from investment and trade activities between China and the countries in this region. The paper employs a regression model to examine the influence of foreign direct investment on trade with data from 2008 to 2022. The findings indicate that a one percentage point increase in China's OFDI corresponds to a 0.054 percent boost in bilateral trade between China and the 16 CEECs. In conclusion, the findings highlight a significant link between OFDI in CEECs and bilateral trade. OFDI opens up new trade opportunities and fosters economic growth in CEECs, thereby promoting the development of bilateral trade. Additionally, Chinese investment drives industrial upgrading and structural adjustments in CEECs, enhancing the competitiveness of bilateral trade.

Authors: Dormany Andras , Orban Zoltan 
Published: February 2024

AbstractThe structural assessment of historical buildings poses a significant challenge for engineers. However, when it comes to historical structures, more commonly used and reliable destructive testing may not always be viable. Instead, non-destructive testing has gained prominence, encompassing techniques like the Schmidt hammer test, georadar, and sonic-based tests.In this paper, the viability of employing sonic testing on historical masonry structures was investigated. This study involves using the measured sonic velocities to identify voids and solid parts within masonry walls. In addition, the purpose is to determine the compressive strength of both mortar and brick constituents and to analyze the effects of moisture and compressive stress on the propagation velocity of waves.

Authors: Jawad Dhay Abd Al Hasan , Ahmed Sahib Shihab 
Published: February 2024

AbstractThis study evaluated the thermal performance of side divergence and uniform micro-channel heat sinks by comparing and contrasting them. Heat transfer and fluid flow characteristics in these micro-channel configurations were studied using computational fluid dynamics simulations employing ANSYS Fluent 2017 code for this purpose. Laminar flow through micro-channels with a Reynolds number of 207 was the subject of the investigation. The goal is to determine how side divergence affects heat dissipation efficiency concerning traditional uniform micro-channels. The results showed that the best divergence ratio is 1.5 that achieved the highest performance. The study also revealed that side divergence micro-channel heat sinks can achieve thermal performance up to 14% higher than uniform micro-channel heat sinks.
Model factor for patch loading resistance of steel plated structures
Authors: Bärnkopf Erzsébet , Kövesdi Balázs Géza 
Published: February 2024

AbstractDirect resistance check by applying advanced numerical models is getting increasingly used for the design of steel slender plated structures. This method has to take into account the same uncertainties as traditional analytical design calculations and should ensure the Eurocode-based prescribed safety level. The application of the model factor gives the possibility to account for the model-related uncertainties. The current study focuses on the determination of the model factor for one specific failure mode, the patch loading resistance. Numerical model has been developed and validated based on laboratory test results. To evaluate the model uncertainties, physically possible modeling differences are introduced, and their effects are evaluated on the resistance. The final aim of the study is to determine the model factor for the analyzed girder type and failure mode based on statistical evaluation.
