Inflammatory pseudotumors in the liver associated with influenza: A case report
Authors: Patel Ankoor , Chen Alexander , Lalos Alexander T
Published: October 2023

Patients with liver cirrhosis are advised to limit their sodium consumption to control excessive fluid accumulation. Salt is the most common form in which sodium is consumed daily. Consequently, various recommendations urge patients to limit salt intake. However, there is a lack of consistency regarding salt restriction across the guidelines. Moreover, there is conflicting evidence regarding the efficacy of salt restriction in the treatment of ascites. Numerous studies have shown that there is no difference in ascites control between patients with restriction of salt intake and those without restriction. Moreover, patients with cirrhosis may have several negative effects from consuming too little salt, although there are no recommendations on the lower limit of salt intake. Sodium is necessary to maintain the extracellular fluid volume; hence, excessive salt restriction can result in volume contraction, which could negatively impact kidney function in a cirrhotic patient. Salt restriction in cirrhotic patients can also compromise nutrient intake, which can have a negative impact on the overall outcome. There is insufficient evidence to recommend restricted salt intake for all patients with cirrhosis, including those with severe hyponatremia. The existing guidelines on salt restriction do not consider the salt sensitivity of patients; their nutritional state, volume status and sodium storage sites; and the risk of hypochloremia. This opinion article aims to critically analyze the existing literature with regard to salt recommendations for patients with liver cirrhosis and identify potential knowledge gaps that call for further research.

Although methane number is widely used to predict knocking occurrence and its intensity, it does not determine a fuel composition uniquely, that means, the knocking intensity by the different composition fuel must show difference even if the same methane number fuels are employed. To establish a novel index, the knocking intensity and the autoignitive propagation velocity, as consequence of spontaneous ignition process, are investigated both experimentally and numerically by using the different composition gaseous fuels with same methane number. Methane/ethane/air and methane/n-butane/air mixtures with the same methane number of 70 and the equivalence ratio of 0.5 were employed. They are rapidly compressed and ignited spontaneously by a Rapid Compression Machine. Ignition delay times, autoignitive propagation velocities, and knocking intensity were measured by acquired pressure histories and high-speed imaging. To survey detail, zero-dimensional and quasi-one-dimensional numerical simulations are involved in this work. Since the temperature dependency on the ignition delay time of each fuel may influence the autoignitive propagation velocity correlated with the knocking intensity, Arrhenius plots of each fuel mixture are acquired by the zero-dimensional reaction simulation to clarify the influence of the mixture composition on the autoignitive propagation velocity. It is necessary to take into account compressible fluid dynamics to predict pressure growth during the spontaneous ignition, the quasi-one-dimensional numerical simulation was carried out. From the above approaches, it was found that the different composition mixture shows the different temperature dependency on the spontaneous ignition delay time, |dτi/dT|, in spite of the same methane number. Meanwhile, the autoignitive propagation velocity takes the same level with the same |dτi/dT|. In other words, autoignitive propagation velocity can change in spite of the same methane number mixture. Since the knocking intensity increases with increase in the autoignitive propagation velocity, it is thought that the knocking for the same methane number mixture is different depending on the temperature range.

Authors: YOSHIDA Kenji
Published: October 2023

The end-gas auto-ignition and associated pressure wave generation in a premixed gas with a spatial distribution is numerically investigated. This study assumes that the auto-ignition phenomenon in the end-gas of PCCI combustion, a next-generation combustion method which is expected to achieve both low fuel consumption and low emissions at a high level. Detailed numerical analysis considering the chemical kinetics on the one-dimensional compressible fluid flow with high spatial and time resolution was performed to clarify the detailed phenomena of the auto-ignition and onset of the pressure wave and its propagation in the end-gas. Followings are results. (1) The pressure wave generations related with the auto-ignition in the end-gas is categorized into two types. The cases that the auto-ignition velocity, which is the localized auto-ignitive propagation velocity relative to the unburned mixture, exceeded the local sound speed, or not. The spatial distribution of the equivalence ratio in the initial unburned mixture affects the auto-ignition velocity. (2) In the cases that the Mach number of the auto-ignition velocity was less than one, the intensity of the pressure wave associated with the auto-ignition is relatively small, and the pressure wave propagates quietly with sound speed. (3) On the other hand, in the cases that the Mach number of the auto-ignition velocity exceeded one, very strong pressure wave is initiated by the auto-ignition. The temperature rise due to the auto-ignition and the pressure rise propagates synchronously toward the unburned mixture.
Investigation of Multiple-Ion-Probe Measurement and Data Analysis Method for Flame Propagation in SI Engines
Authors: Yatsufusa Tomoaki
Published: October 2023

In the multiple-ion probe method, multiple ion probes are installed on the combustion chamber wall, and each individual ion probe detects flame contact and records the time of flame arrival. From the recorded data, it is possible to reconstruct the dynamic behavior of the flame surface and, for example, indirectly visualize the inside of the combustion chamber as a moving image. In this study, 32 ion probes were used to record flames propagating in a 2-stroke SI engine, and various analysis and evaluation methods other than indirect visualization was investigated and evaluated. Although it is possible to extract local flame propagation velocity, direction of propagation, etc. from the reconstructed flame propagation in the engine, an analysis method that aims to find the characteristics of the overall combustion in the actual combustion during a single cycle from a single feature, rather than local data, was investigated. Five types of features were extracted from the flame detection time data interpolated between ion probes by cubic splines. These features were used to investigate the characteristics of the data obtained from the multiple-ion probe measurement. It is expected that multiple-ion probe measurement can be used in combination with pressure measurement and visualization measurement to obtain more detailed information on combustion in the engine.

Machine learning is used for the research and development of ITS services and the rider assistance for on-road motorcycle racing. Meanwhile, rider assistance systems for off-road motorcycles have yet to be developed, partly due to the complexity of the measurement conditions, as described in the previous paper. This research aims to create a reliable AI which is capable of classifying typical jump behaviors in off-road riding by machine learning to create a rider assistance system for off-road motorcycles. Motorcycle manufacturers and certain research institutes use motion sensors to collect data, but the data is obtained from a limited number of vehicles and riders. The creation of a rider assistance system requires a large amount of validation data. Furthermore, it is desirable to achieve the target with data that can be measured in mass-produced vehicles, which will make it possible to collect data even from general users. In addition, recent machine learning models are black boxes because it is difficult for people to understand the entire process, and it is necessary to evaluate the validity of the results. The approaches are as follows. (1) Using data that can be measured in mass-produced vehicles, the number of features was increased as a preprocessing step. (2) The validity of the machine learning model was evaluated by focusing on the SHAP value, one of the XAI techniques. As a result, (1) classification ability has improved. (2) correspondence between the number of features with large SHAP values and physical phenomena has been obtained. In other words, it has been confirmed that appropriate number of features have been selected for classification. These results have indicated that the created AI has a certain level of classification ability and that the judgment results can be trusted.

This paper discussed the sound quality which assumed important factor in the development of outboard engines in the 183 to 257 kW class in the future. Many kinds of industrial product development dealt with sound quality, and there were many examples using sound quality index adapted customer requirements or products usage. In case of outboard engine development, there were examples of noise reduction and compliance with noise regulations, but there was almost no example of sound quality development. This research proceeded a questionnaire survey of 90 boat owners who were listening to several cruising engine sounds in main market, US. From this result, authors discussed customer trend and extracted 3 sound quality indexes, luxury, deep and sporty, which were demanded in our target class. Next step was that authors made simulation sounds referring 3 sound quality indexes to verify customer’s trend. Using these simulation sounds, authors re-tried to a questionnaire survey, we were able to confirm trends in sound quality preferred by customers. Finally, authors suggested that it was important for realizing customer’s preference sound quality to control the air intake noise and the gear noise.

Published: October 2023

Virtual sensing, i.e., the method of estimating quantities of interest indirectly via measurements of other quantities, has received a lot of attention in various fields: Virtual sensors have successfully been deployed in intelligent building systems, the process industry, water quality control, and combustion process monitoring. In most of these scenarios, measuring the quantities of interest is either impossible or difficult, or requires extensive modifications of the equipment under consideration – which in turn is associated with additional costs. At the same time, comprehensive data about equipment operation is collected by ever increasing deployment of inexpensive sensors that measure easily accessible quantities. Using this data to infer values of quantities which themselves are impossible to measure – i.e., virtual sensing – enables monitoring and control applications that would not be possible otherwise.

In this concept paper, we provide a short overview of virtual sensing and its applications in engine settings. After reviewing the current state-of-the-art, we introduce several virtual sensor use cases that have successfully been deployed in the past. Starting from a simple phenomenological model connecting the ion current from a spark plug with fuel quality, we move over physical models that infer in-cylinder pressure from the acceleration signal of knock sensors to a deep learning model that estimates combustion parameters from the vibration of the crank shaft. In this manner, this study is designed as a “teaser”, with the intention of incentivizing further development within the sector by providing the aforementioned information. We close the paper by discussing possible applications of virtual sensing in small engines.
Use of Detailed Hydrocarbon Emission Analysis to Identify Synergistic Effects in Renewable Gasoline Fuel Blends for Significant Reduction of Aromatic Hydrocarbon As Well As Total Hydrocarbon Emissions of a Small Gasoline-Powered ICE
Authors: Pfleger Georg Stefan , Schober Sigurd
Published: October 2023

With rising awareness of man-made climate change the interest in measures to reduce CO2 and other greenhouse gas (GHG) emissions increases. The use of renewable liquid fuels is one way to achieve reduction of GHG emissions. Due to their different chemical composition, gasoline fuels containing significant shares of renewable components also produce different pollutant emissions including hydrocarbon (HC) emissions amongst others such as particular matter, carbon monoxide, and nitrogen oxides. In this study the effects of renewable fuel components on amount and type of individual hydrocarbon components in exhaust emissions of a small gasoline-powered internal combustion engine were investigated via gas chromatographic analyses. Therefore, three different gasoline fuels with varying degrees of sustainable components and their respective HC exhaust emissions were investigated in single compound resolution. HC emissions could be categorized into combustion side products and unburned fuel fractions according to their origin. Both fractions showed significantly different sensitivity on change of engine operation. Whilst combustion side product emissions showed little sensitivity, unburned fuel emissions proved to be highly sensitive on engine operation. The combustion rates of the unburned fuel fraction of HC exhaust emissions were investigated via comparison to the composition of the fuels used. Thereby, large differences in combustion rates of different fuel components could be identified with aromatics generally showing poorest conversion. Promising synergies between renewable gasoline compounds such as EtOH or EtBE and the hydrocarbon part of fuels (be it synthetic or conventional gasoline) could be identified which showed significant reduction of both total hydrocarbon emissions as well as especially dangerous aromatic hydrocarbon emissions.

The objective of this experimental investigation was to analyze the effect of various exhaust gas aftertreatment technologies on particulate number emissions (PN) of an MPFI EU5 motorcycle. Specifically, three different aftertreatment strategies were compared, including a three-way-catalyst (TWC) with LS structure as the baseline, a hybrid catalyst with a wire mesh filter, and an optimized gasoline particulate filter (GPF) with three-way catalytic coating. Experimental investigations using the standard test cycle WMTC performed on a two-wheeler chassis dynamometer, while the inhouse particulate sampling system was utilized to gather information about size-dependent filtering efficiency, storage, and combustion of nanoparticles. The particulate sampling and measuring system consist of three condensation particle counters (CPCs) calibrated to three different size classes (SPN4, SPN10, SPN23). The study revealed that all three aftertreatment technologies were effective in reducing PN from the motorcycle, although the standard OEM LS honeycomb is already below the passenger car Euro 6 particle emission limits [1]. However, the GPF with a three-way catalytic coating showed the highest filtering efficiency with a significant decrease in PN emissions, particularly SPN10 and above, compared to the baseline. The hybrid catalyst with a wire mesh filter was also effective with a slightly better reduction in PN emissions compared to the baseline, but it had better backpressure behavior than the GPF and a significantly robust design. The reduction efficiency of the TWC was consistent with prior research. Moreover, the study highlighted the importance of considering the size distribution of particles when assessing aftertreatment strategies. The GPF and the hybrid catalyst with a wire mesh filter demonstrated high filtering efficiencies across all size classes. The TWC with LS structure was less efficient, particularly for the larger size classes, as previously reported [2].

In conclusion, this study emphasizes the need to consider both the overall reduction of PN and the size-dependent filtering efficiency of different aftertreatment strategies when assessing their effectiveness in reducing emissions from motorcycle exhaust.

Published: October 2023

In recent years there has been a significant focus towards bringing EVs to the market because of the regulations in carbon emissions and increased customer awareness. Unlike the passenger car and two wheelers that are mainly used for personal transportation, the IC engine three wheelers are widely used as commercial vehicles to carry passengers and loads. Converting an existing vehicle in the market to an electric reduces emission and increases sustainability. Large battery capacity is used in these vehicles to achieve the range, thus increasing the initial cost and making it unpopular among customers. However, requirements of the three-wheeler electric vehicles are high in big institutions, resorts, golf courses, hospitals and many other places for internal campus transportation. It is not commercially viable to make a complete design of Body-In-white (BIW) & suspension for this application. Hence, a method of converting an existing three-wheeler into an EV is explained here. Various layout options for battery location is considered and optimized layout is decided based on significant factors. Similarly, the selection of traction motor is explained in detail. An EV model is presented for calculating the range and the test results are presented. We converted an IC engine three-wheeler into an electric, calculated the resistances, EV components specifications and verified with a prototype against the design requirements.

The rise in incidence rates of invasive candidiasis warrants an increase in attention and efforts toward preventing and treating this virulent infection. Cardiac involvement is one of the most feared sequelae and has a poor prognosis. Despite the introduction of several novel antifungal agents over the past quarter century, complications and mortality rates due to Candida endocarditis have remained high. Although fungal endocarditis has a mechanism similar to bacterial endocarditis, no specific diagnostic criteria or algorithm exists to help guide its management. Furthermore, recent data has questioned the current guidelines recommending a combined approach of antifungal agents with surgical valve or indwelling prostheses removal. With the emergence of multidrug-resistant Candida auris , a focus on improved prophylactic measures and management strategies is necessary.

Published: October 2023

Oliver Wendell Holmes es generalmente reconocido como el “padre fundador” del Derecho contemporáneo en Estados Unidos de América, ejerciendo una influencia determinante en prácticamente todas las corrientes de pensamiento jurídico, aunque con particular impacto en las distintas direcciones iusrealistas, pues mantuvo una concepción realista del Derecho muy crítica con el formalismo jurídico imperante en su época. Para él el Derecho es un Derecho vivo y como tal dinámico y cambiante a impulso de las exigencias del presente en el que ha de ser aplicado. En su opinión el Derecho no tiene tanto una “esencia” lógico formal como existencia vital que se resuelve en la “experiencia” jurídica (es conocida la formulación de su concepción del Derecho: “La vida del Derecho no ha sido la lógica, sino la experiencia”, hecha en su libro más importante e influyente, The Common Law, cuyo objetivo principal era presentar una visión general del Common Law, con un enfoque explícito que acoplaba historia y jurisprudencia, realzando el valor la experiencia jurídica y la fijación de estándares jurídicos en varios campos del Common Law). Publicó obras jurídicas magistrales, pero también su pensamiento tuvo una repercusión extraordinaria en el ámbito judicial a través de sus Votos Particulares discrepantes (se anticiparían a su tiempo, porque años después su doctrina judicial sería acogida por la Corte Suprema de Estados Unidos, y ya conforme al giro legislativo marcado por la “New Deal”).

Em um jogo de futebol, os jogadores estão sujeitos às altas demandas cognitivas. Essas demandas podem gerar uma fadiga mental. No entanto, os indivíduos possuem diferentes capacidades para suportar essas demandas cognitivas, o que justifica estudos que discriminem grupos de jogadores. Dessa forma, este estudo teve como objetivo comparar as ações táticas de jogadores com alto e baixo desempenho tático em duas condições: (1) com e (2) sem fadiga mental. Dezoito jogadores de futebol da categoria Sub-17 foram incluídos na amostra. O Sistema de Avaliação Tática no Futebol (FUT-SAT) foi utilizado para avaliar as ações táticas dos jogadores e o Stroop test (incongruente) foi utilizado para induzir a fadiga mental. Foram realizadas estatística descritiva (média e desvio-padrão), os testes de Shapiro-Wilk e ANOVA (com ajustamento de Bonferroni). Em todos os casos, o nível de significância adotado foi de p<0,05. As análises foram efetuadas no software SPSS 25 (IBM, New York, EUA). Os resultados apontam que os jogadores com alto desempenho tático na condição sem fadiga mental, realizam mais ações ofensivas e defensivas em relação a eles mesmos na condição de fadiga mental e em relação aos jogadores com baixo desempenho nas duas condições. Conclui-se que os jogadores com alto desempenho tático realizaram mais ações ofensivas e defensivas sem fadiga mental em relação aos seus pares com baixo desempenho tático.

Taxation is one of the main sources of income for the state, however state revenues from the taxation sector have not met the government's expectations every year. This is caused by government policies that are less effective in encouraging tax compliance and a lack of taxpayer awareness about tax payment obligations for industries and companies. This research aims to determine the influence of company size, capital intensity, tax burden on tax avoidance in food and beverage companies registered on the IDX in 2020-2022 and the simultaneous influence of company size, capital intensity, and deferred tax burden on tax avoidance in food and beverage companies listed on the BEI in 2020-2022. The method used in this research is a quantitative research method. In this research, the data used comes from secondary data. The data source used is the audited financial reports of companies registered on the Indonesian Stock Exchange (BEI) for the 2020-2022 period. This data can be accessed via the official IDX website, namely www.idx.co.id. The researcher used the ippurposive sampling method to select the sample, with independent variables in the form of company size, capital intensity and deferred tax burden and the dependent variable, namely tax avoidance. The data analysis methods used are descriptive statistical analysis, classical assumption testing, regression analysis, hypothesis testing and identification test. The results of this research show that Firm size has a significant negative effect on tax avoidance, Capital intensity has a significant negative effect on tax avoidance, Deferred tax burden has a significant positive effect on tax avoidance, and Firm size, capital intensity and deferred tax burden simultaneously have an effect on tax avoidance.

Настоящее исследование фокусируется на разработке и оптимизации подхода управления ресурсами в распределенных динамических вычислительных системах. Мы представляем новый гибридный метод, комбинируя динамическое управление частотой и напряжением с использованием нейронных сетей обнуления (НСО) для минимизации выбросов углекислого газа и снижения энергопотребления. Исследование включает систематические эксперименты, в ходе которых анализируется структура и параметры НСО для минимизации ошибок. Применение метода на реальных данных вычислительной сети NorduGRID продемонстрировало его эффективность, снижая выбросы CO2 на 9,4% за 30 дней при сохранении требуемой производительности. и является значимым вкладом в область развития энергоэффективных вычислительных систем. Проведены эксперименты на крупных вычислительных системах, включая более 2,7 миллиарда узлов с использованием реальных данных о выбросах углекислого газа.  Полученные результаты подчеркивают перспективность гибридных подходов и использование нейронных сетей для оптимизации управления ресурсами в динамических вычислительных средах. Наш метод обеспечивает устойчивое и энергоэффективное выполнение вычислительных задач в условиях ограниченных ресурсов и является значимым вкладом в область развития энергоэффективных вычислительных систем. Разработанный подход предоставляет перспективы для оптимизации работы вычислительных систем, учитывая динамичный характер современных вычислительных задач и ограниченные ресурсы энергопотребления.

The present work aimed to identify the effects of knowledge, attitudes, and practices (KAP) of poultry handlers on the prevalence of Campylobacter along the poultry production chain in Peninsular Malaysia. A total of 1230 microbiological samples were collected from five companies in different Malaysian states. The sampling points involved the entire poultry supply chain from the farm to the retailer. The collected samples were subjected to bacteriological isolation and morphological identification for microbiological analyses. All Campylobacter-positive samples were further confirmed with molecular identification by using a polymerase chain reaction. Campylobacter prevalence in poultry farms, processing plants, and retailers were identified. For the KAP survey, 300 respondents answered a questionnaire evaluating their levels of KAP regarding food safety while handling live birds and subsequently poultry products after slaughtering. Overall, the mean KAP scores of the workers at farms, processing plants, and retail outlets were assessed. The survey data indicated that even though the overall KAP levels of the poultry workers were excellent, the bacterial prevalence of Campylobacter was still high. In conclusion, the KAP of poultry handlers had insignificant effects on the prevalence of Campylobacter along the poultry production chain in Peninsular Malaysia.
Probiotic yoghurt fortified with rosehip seed powder: Viability, physicochemical, and sensorial properties
Authors: Gurbuz Basak , Demirci Ahmet Şükrü
Published: October 2023

The impact of rosehip seed powder (RSP) fortification (1, 2, and 3%) on some physicochemical characteristics and bacterial survival of set type probiotic yoghurt was evaluated during 21-d storage at 4°C. Textural, microstructural, total phenolic content, antioxidant activity, and sensorial attributes were also assessed in the samples, with and without RSP fortification. Milk was fermented by yoghurt cultures with the inclusion of the probiotic cultures comprising Lactobacillus acidophilus and Bifidobacterium animalis subsp. lactis. The total solid, protein, and total phenolic contents in yoghurts fortified with RSP were significantly higher than control, and an enhancement in the yoghurt's antioxidant capacity and firmness, while a reduction in yoghurt's adhesiveness and syneresis occurred (p < 0.05). However, sensory scores were lower in RSP-fortified yoghurts than in control. Throughout 21-d storage, the yoghurt's titratable acidity increased while its syneresis and pH decreased. The present work also determined that RSP fortification of probiotic yoghurt increased (p < 0.05) in L. acidophilus and B. animalis subsp. lactis growth (up to 8.24 and 8.10 log CFU/g, respectively) as compared to their respective controls (7.84 and 7.83 log CFU/g, respectively), and probiotic counts in yoghurts fortified with RSP remained over 6 log CFU/g at the end of storage. The documented knowledge of fortifying probiotic yoghurts with RSP could inspire the dairy industry to generate a novel synbiotic product while utilising wasted rosehip seeds as processing waste.
