The incidence of small ruminant pestivirus infections in Greece remains unknown as they have not been diagnosed in the country since 1974 when the most recent Border Disease Virus (BDV) outbreak was reported. The objective of our study was to explore the possible occurrence of pestiviral infections among sheep and goat farms in Greece and to further determine the variants of major concern. Thus, serum samples were collected from 470 randomly selected animals belonging to 28 different flocks/herds. ELISA on p80 antibody revealed the existence of seropositive animals in four out of the 24 studied sheep flocks, whereas all the goats in the four studied herds were seronegative. Viral RNA and antigens were detected in two sheep out of the four seropositive flocks by RT-PCR and ELISA, respectively. Sequencing and phylogenetic analysis showed that the newly identified Greek variants were closely related to the strains of the BDV-4 genotype. One of the BDV-positive sheep demonstrated the diagnostic profile of a persistently infected (PI) animal, providing additional information regarding the source of the infection. This is the first molecular identification of BDV isolates in Greece. Our findings indicate that BDV infections are likely to remain undiagnosed, highlighting the need for further epidemiological studies and active surveillance programs to determine the prevalence and impact of BDV infections on a countrywide level.

Published: May 2023

Little is known about thyroid diseases in ruminants, probably due to the lack of diagnosis techniques developed in this species. However, thyroid ultrasound (TU) is widely used in human and in companion animal’s medicine. It is a cheap and non-invasive examination, which allows for the identification of thyroid structures or diffuse diseases. The aim of this study was to evaluate the accuracy of TU in five calves and five cows through inter- and intra-observer repeatability. The size of the thyroid gland was measured from three views: left sagittal, right sagittal and transverse; nine measurements per view. The intra-observer coefficient was calculated for each observer. For the inter-observer, the first observer was a board-certified imagist (European College of Veterinary Diagnostic Imaging diplomate), the second was a board-certified specialist in bovine and herd management (European College of Bovine Health Managementdiplomate) and the third was an in-trained veterinarian for the TU. They each scanned the thyroid gland successively, following the same method. The intra-observer variabilities for observers 1, 2 and 3 were 8.22%, 5.53%, 5.38%, and 7.18%, 8.65% and 6.36%, respectively, for calves and cows. The inter-observer variability for calves was 10.4% and for cows, 11.8%. This study confirms the feasibility of repeatable intra- and inter-observer TU-estimated measurements in cattle.

Chronic non-septic pleural effusion is a condition that frequently may occur because of lung or pleural neoplasia, or chylothorax refractory to surgical treatment, in dogs. Effusion management can be performed with multiple pleurocenteses or the application of chest drains. New modified vascular devices have been used for patients with chronic diseases; they offer the advantage of allowing home management and do not require hospitalization. Eight PleuralPortTM devices were applied in seven dogs during thoracoscopic exploration and biopsy procedures; five were affected by mesothelioma; one by lung metastases from a mammary carcinoma; and one by chronic chylothorax. The median time of surgical procedure was 51 min; one developed pneumothorax post-operatively that resolved within 12 h after repeated drainage; one device was obstructed after 45 days and was successfully managed by flushing. All patients were discharged after 24 h. The median duration of port insertion in cancer patients was 5 months and those dogs were euthanized because of tumor progression; in the dog with chylothorax, the device was removed after 1 year when the effusion had resolved.
Improved Kalman-Filter-Based Model-Predictive Control Method for Trajectory Tracking of Automatic Straddle Carriers
Authors: Ding Zonghe , Lin Shuang , Gu Wei , Zhang Yilian
Published: May 2023

This paper considers the trajectory tracking problem for a class of automatic straddle carriers (ASCs) with external interferences and the overturning constraints. First, the steering and the dynamics of the ASC are analyzed and the mathematical model of the ASC is established. Then, considering the impact of external interferences on the trajectory tracking accuracy, an improved dynamic Kalman filter is designed in order to obtain the state estimation of the ASC. Based on the obtained state estimation, a model-predictive control method is proposed which takes the anti-overturning constraints into account. In addition, the improved Kalman-filter-based model-predictive control (iKFMPC) algorithm is summarized for the considered ASC to travel smoothly along the given trajectory while meeting the overturning resistance. Finally, simulation analyses demonstrate the effectiveness and superiority of the proposed method.
Patient Safety Trends in 2022: An Analysis of 256,679 Serious Events and Incidents From the Nation’s Largest Event Reporting Database
Authors: Kepner Shawn , Jones Rebecca
Published: May 2023

Background

Pennsylvania is the only state that requires acute care facilities to report all events of harm or potential for harm. The Pennsylvania Patient Safety Reporting System (PA-PSRS) is the largest repository of patient safety data in the United States and one of the largest in the world, with over 4.5 million acute care event reports dating back to 2004. Herein, we examine patient safety event reports submitted to the PA-PSRS acute care database in 2022 and compare them to prior years.

Methods

We extracted data from PA-PSRS and obtained data from the Pennsylvania Health Care Cost Containment Council (PHC4). Counts of reports were calculated based on report submission date, and rates were calculated based on event occurrence date and calculated per 1,000 patient days for hospitals or 1,000 surgical encounters for ambulatory surgical facilities (ASFs).

Results

A total of 256,679 reports were submitted to PA-PSRS in 2022, representing an 11.1% decrease from 2021. Three facilities collectively submitted 18,601 fewer reports in 2022 compared to 2021, which accounted for 57.8% of the overall decrease. Reports of serious and high harm events increased by 7.7% and 11.1%, respectively. Of the 256,679 reports submitted, 95.9% were from hospitals, 3.9% were from ambulatory surgical facilities, and 0.2% were from birthing centers and abortion facilities. The vast majority of the 2022 reports were incidents (96.2%) as opposed to serious events (3.8%). For each of the past five years, the most frequently reported event type was Error Related to Procedure/Treatment/Test, accounting for 32.8% of all submitted acute care event reports in 2022. The second, third, and fourth most frequently reported event types in 2022 were Complication of Procedure/Treatment/Test, Medication Error, and Fall, accounting for 15.6%, 13.2%, and 12.8% of submitted reports, respectively. The reported event rate based on occurrence date for hospitals in the first half of 2022 was 27.5 reports per 1,000 patient days. For ASFs, the reported event rate for the first half of 2022 was 9.4 reports per 1,000 surgical encounters.

Conclusions

There was a decrease in the number of incident reports submitted to PA-PSRS in 2022 and an increase in serious and high harm event reports. PSA will continue to work with facilities, monitor reporting, and take further action as needed.

Nos últimos anos observou-se um interesse crescente na determinação dos níveis de nitrato em produtos alimentícios, essencialmente devido ao potencial de redução de nitrato em nitrito, que é conhecido por ter efeitos adversos na saúde humana e animal. O nitrato é intermediário no ciclo do nitrogênio e sua alta concentração na água é indicador de baixa qualidade (Wang et al.). A determinação direta em águas é realizada na região do ultravioleta em meio ácido e no comprimento de onda específico (205 nm) (APHA, 2012). Esse procedimento é muito útil em águas potáveis, mas suscetível a efeito de matriz em águas com pH alcalino ou com elevada força iônica (APHA, 2012). Assim, propôs-se no presente trabalho utilizar o método de adição de padrão (MAP) em comparação com o procedimento de calibração convencional (MC) descrito no livro de normas “Métodos Físico-químicos para Análise de Alimentos” (técnica 195/IV) (IAL, 2008) e executado no Laboratório de Análises Físico-químicas do Instituto Adolfo Lutz - Centro de Laboratório Regional de São José do Rio Preto X, em contrapondo, ao procedimento de adições cumulativas do padrão (MAP-C). Diante disso, foi realizada uma comparação entre os métodos MC, MAP e MAP-C, objetivando viabilizar e validar um tratamento de dados diferente do original para a estimativa do cálculo da incerteza, destacando para esse fim a abordagem bottom-up. Além, de identificar as limitações dos métodos que podem ser empregados para a vigilância da qualidade da água mineral e de abastecimento. De acordo com a ABNT NBR ISO/IEC 17025:20175, foram determinados os parâmetros de desempenho para os três procedimentos: limite de detecção, limite de quantificação, exatidão, precisão intermediária e a incerteza. Para a execução dos ensaios as condições ambientais foram monitoradas e estabelecidas as curvas de calibração (absorbância x concentração da solução padrão de nitrato de sódio, 9,98 mg L-1, calculado em N, para MC, MAP e para o MAP-C uma solução de 2,00 mg L-1), com o objetivo de determinar a concentração de nitrato de sódio. Assim, foram ensaiados 100 mL provenientes de 4L das amostras de água mineral de três marcas com diferentes pH (8,44; 6,96; e 5,77). Os parâmetros de desempenho dos procedimentos foram determinados a partir de diluições das soluções padrão e os resultados obtidos.

O presente artigo teve como objetivo realizar uma revisão narrativa de literatura de forma a esclarecer o prognóstico da Terapia de Ressincronização Cardíaca (TRC) em pacientes com Insuficiência Cardíaca (IC). A IC consiste em uma síndrome clínica em que o coração não consegue suprir as demandas metabólicas do organismo ou quando essa demanda é suprida mediante a grandes pressões, seja por déficit de contração ou relaxamento do miocárdio. No Brasil, entre os anos de 2008 e 2017, foi a principal causa de hospitalização devido às alterações cardíacas e vasculares, que são consequências de doenças como hipertensão arterial sistêmica, isquemia do miocárdio, doenças valvares e cardiomiopatias. Nos últimos anos, novos métodos de tratamento foram sendo descobertos e utilizados, principalmente relacionados à mudança do estilo de vida, à farmacologia e ao uso de dispositivos implantáveis. A eficácia da TRC (dispositivo implantável) está comprovada por estudos clínicos diversos que demonstram uma resposta favorável e benefícios quanto à sintomatologia, melhora da qualidade de vida, redução das internações hospitalares e diminuição da mortalidade. Nada obstante, a resposta ao tratamento é individualizada, sendo influenciada pelas características clínicas do paciente.

Authors: Santos Michelle Bianca Barbosa , Marinho Ana Wanda Guerra Barreto
Published: May 2023

Pacientes portadores de doença renal crônica tem um risco cardiovascular aumentado. E a doença cardíaca pode estar presente em estágios iniciais e principalmente nos pacientes em estágio terminal. Uma das complicações da doença são os distúrbios do eixo mineral e ósseo, que à medida que a função renal diminui causa a perda progressiva da capacidade de manter o equilíbrio desse eixo. Com esse desequilíbrio pode haver calcificação cardiovascular como a calcificação de válvulas cardíacas que é muito prevalente nesses pacientes. Assim, esses pacientes devem ser frequentemente avaliados para prevenção e diagnóstico precoce dessas complicações, uma vez que as opções de tratamento são limitadas.

Este artigo analisou, a partir de uma revisão narrativa de literatura, a oferta dos cuidados paliativos (CP) na atenção primária à saúde, evidenciando as dificuldades encontradas para a realização de uma assistência adequada. Os CP são de extrema importância uma vez que visam proporcionar conforto aos pacientes e familiares diante de uma doença que ameace a vida. Logo, identificar os obstáculos relacionados à oferta adequada desse cuidado e fomentar meios para solucionar tais adversidades torna-se essencial para uma assistência à saúde de qualidade. Dentre os principais problemas encontrados destacam-se o crescimento da demanda de pacientes para o CP, longitudinalidade do cuidado através de visitas domiciliares, falta de recursos tecnológicos, limitação à abordagem multidisciplinar, falta de apoio aos cuidadores, mas, sobretudo, o despreparo dos profissionais ocasionado, principalmente, pelo contato insuficiente com o tema, o que dificulta a abordagem integral do paciente. Diante disso, torna-se evidente a necessidade da criação de medidas que disseminem o conhecimento e informação em relação aos CP, para que os pacientes e suas respectivas famílias tenham cada dia mais amparo em um momento de tamanha vulnerabilidade.

Published: May 2023

Sunflower oil is known for its therapeutic properties and culinary use. It is an important alimentary source of tocopherol and unsaturated fatty acids, and is used especially for wound healing. Studies indicate that it also has antimicrobial potential. The ozonation of oils of vegetable sources has been explored as a way to enhance their therapeutic properties; however, studies that provide evidence of such benefits are still lacking. In the field of veterinary medicine, such data are even more scarce. In this study, the antimicrobial activity of ozonated sunflower oil was compared to that of non-ozonated oil, in an in vitro system. We used clinical isolates of Escherichia coli, obtained from intrauterine lavages of mares with endometritis. Tests were conducted using the minimum inhibitory concentration method. Our data open doors for discussion on the use of sunflower oil, with or without ozone treatment, for therapeutic purposes in veterinary medicine.

Published: May 2023

This paper reports a comparison of different types of springs used in MEMS based capacitive accelerometers. In this work MEMS based Single-axis accelerometers are designed using different Suspension systems. Analysis of the structure is done for resonant frequency of 2kHz. Analytical modeling of the different suspensions is presented for the specified frequency. Stress, displacement and capacitive analysis of the accelerometer is done. The sensitivity of the accelerometer with parallel beam  suspension is 70nm/g, 50nm/g for folded beam suspension and 35nm/g for serpentine beam suspension. Hence parallel beam suspension has 0.7 times improved sensitivity than folded beam and 2 times better than serpentine suspension accelerometer. Whereas the stress obtained for folded beam is better than the other two. Hence  Parallel beam suspension is preferred for higher sensitivity and accuracy whereas Folded beam suspension is preferred for greater structural stability By comparing these devices, it is concluded that a compromise on certain parameters is required in order meet the requirements. If there is higher displacement sensitivity then there is lower mechanical stability and vice versa. The simulations are carried out using COMSOL Multiphysics.

Authors: G Ekwueme O. , O Aronu Charles
Published: May 2023

In this study, the multipurpose objective of development in the Anambra River basin was examined. The study's goals are to determine the net benefits of the various objectives under each purpose currently carried out by the Anambra River Basin, to identify the best way to achieve the goals, and to show, through logical and mathematical reasoning, how money could be allocated to the various goals of a dam project in Anambra State effectively. Economic Efficiency (EE), Regional Economic Redistribution (RER), Social Well-Being (SW), Youth Empowerment (YE), and Environmental Quality Improvement are the objectives taken into account in the study (EQI). The optimization problem in the multi-purpose-objective development of the Anambra State river basin was solved utilizing the multi-start optimization method. The study showed that the basin would achieve enormous financial benefits if it used its N15.0 billion strategic development budget over four years for various purposes as illustrated. The results showed that the following allocation of the five purposes should be optimized simultaneously for an N15.0 billion four-year strategic development fund: EE should receive N0.762 billion, RER should receive N0.594 billion, SW should receive N0.649 billion, YE should receive N0.683 billion, and environmental quality improvement should receive N4.768 billion.  It was found that Environmental Quality Improvement was allocated the higher amount while Regional Economic Redistribution was allocated the least amount for the development. The study's findings recommended that the management of the basin stop the practice of allocating funds to various uses at their discretion, which has led to significant oversight and the improper distribution of scarce resources. As a result, every fund distribution must be justified using logic and mathematics. To increase the accuracy of the data, the Anambra State River Basin Development Authorities must intensify record-keeping activities.

Nowadays, the motorcycle key is assumed to be too old-fashioned because it still uses physical metal, is easily eroded, and is loose. A driver's license (SIM) is a card that needs to be brought when driving. It used the driver as evidence that they have a driving permit from the police. On the other hand, identity cards such as SIMs already have RFID technology. However, this technology is rarely used correctly. This study aims to design a motorcycle security system using RFID and, likewise SIM card model as a motorcycle ignition key. The study showed that the system could perform or operate well. Motorcycle key using RFID as a dummy SIM makes people easier who are careless in putting their motorcycle keys.

The importance of alternative fuels and their share in total energy consumption is constantly growing. The reason is, on the one hand, the saving of the gradually decreasing reserves of fossil fuels and also the effort to gradually reduce the emissions of carbon dioxide and other harmful substances. This article is another in a series of articles focused on an overview of the technical requirements and possibilities for testing alternative fuels. These articles aim to provide an overview of the required properties of individual alternative fuels, an overview of the prescribed analytical tests, and explain their relevance. This article focuses on liquid alternative fuels containing ethanol.
Ethanol is currently the most widespread alternative oxygen fuel and, at the same time, also a biofuel. In pure form (E100), ethanol is used only exceptionally. Far more often, it is used as a bio-component of gasoline fuels.
This article provides an overview of the technical requirements prescribed by legislation and relevant standards for ethanol for blending into gasoline fuels, and fuels containing ethanol. From ethanol-gasoline blends, E5, E10, and E85 are discussed. In addition, E95 fuel is discussed as well. The article also presents prescribed analytical tests for monitoring the quality of these fuels, or fuel components.
Generally, in ethanol fuels or pure ethanol according to EN 15376, the composition is mostly analysed by GC. GC analysis determines the content of main and secondary oxygen components and/or the content of other impurities. In addition, the water content, total acidity, chloride and sulfate content, non-volatile impurities content, and the content of selected metallic and non-metallic elements, especially sulfur, are monitored in these matrices. For fuels intended for combustion in gasoline engines (E5, E10, and E85), important monitored parameters are also vapor pressure, oxidation stability, as well as density and corrosion on copper.
Hydrogen production using nuclear power plants

Published: May 2023

In the coming years, the global demand for hydrogen can be expected to grow gradually, with increasing pressure to produce without the use of natural gas or oil. As a result, possible ways to produce hydrogen that will have a lower carbon footprint are being sought. Apart from the use of renewable energy sources, nuclear energy appears to be another possible source. This article provides an overview of available and suitable technologies that use nuclear energy. These include in particular water electrolysis, thermochemical decomposition of water or hybrid cycles. The article also includes an overview of individual research programs in the world.
A nuclear power plant, in conjunction with hydrogen production, could serve as a backup flexible energy source in addition to coal and gas power plants to stabilize fluctuations in the electrical transmission system due to the operation of renewable energy sources.
Low-temperature treatment of waste crosslinked polyethylene with ruthenium catalyst

A method of processing of waste cross-linked polyethylene (PEX) by low-temperature pyrolysis with a Ru/Al2O3 catalyst was developed. The catalyst used, even in a small amount, significantly supported the splitting of the PEX structure, so that the yield of the key product, oil, reached 90%. Further, an energy gas with a HHV of 48.5 MJ/kg was obtained, suitable for further use. The minority products were paraffin and a solid carbonaceous residue. A mass and energy balances of the process and their comparison with those without a catalyst were carried out. In the case of catalyzed pyrolysis, it was found that 96.5% of the energy content of the starting raw material was preserved in the products with a high utility value. More in details, the ruthenium catalyst favorably affected the low-temperature pyrolysis of waste PEX, as the amount of main product, oil, obtained with the catalyst was clearly higher (90%) compared to the amount of oil obtained without one (85%). The composition of the pyrolysis gas was also favorably influenced by the ruthenium catalyst as the gaseous hydrocarbon contents were significantly higher compared to those of uncatalyzed pyrolysis. A small amount of Ru was needed for such effects, since the Ru/PEX ratio was 0.75/100 (g/g). This fact compensates, or at least partially, the relatively high price of this catalyst compared to, for example, nickel-based or FCC catalysts. Minority products, paraffin and solid carbon residue are well usable in practice. Paraffin is a necessary substance in a number of industries (medicine, cosmetics, wood impregnation, construction, candle production, skiing wax production); the solid carbonaceous residue can be used as clean sulfur-free and low-ash fuel.
Flue gas condensation of solid fuel fired heating plant

Published: May 2023

In the Czech Republic, increasing trend exists in utilization of biomass as a fuel in heating and power plants. This is preferred solution by EU Climate plans, and it is connected with some economic benefits (e.g. green bonuses, guaranteed purchase price), on the other hand the combustion of fossil fuels is penalized (EU ETS – Emission Trading System). There are many types of biomass with different parameters but one of the most discussed are wooden resides because of its quantity.
There are big differences between quality parameters, especially in moisture content, which is decreasing the LHV. There are some technologies which can decrease moisture. Dryer technologies could be simple so-lution, but final decreasing of moisture is quite low. More effective is application of flue gas condensation. This technology is well known for gas-fired boilers but nowa-days is still more often build by new solid fuels-fired plants.
This deals with design of condensation technology for existing heating plant in Mladá Boleslav. The fuel mixture is based on wood residues (70 %) and pelletized plant biomass (30 %). The calculation was done for three boilers for soild fuels – two same CFBs (steam production 100 t·h-1) and one BFB (steam production 80 t·h-1). Moisture content was calculated for two cases of wooden residues with moisture content 35 and 50 %. System of condensation include three step water scrubber, heat ex-changer, heat pump and humidifier of combustion air.
The final designed output of unit for BFB is 12.7 MW (19 MW for each CFBs), but from these the output of heat pump is 5 MW (7.5 MW). The source of heat for heating pumps is steam, which can be used in current heater, so the final net output from condensation is 7.7 MW (11.5 MW). These parameters are only for 50 % of moisture content in wooden residues.
The application of these system is not cost-effective for moisture content of fuel around 35 %. It is possible to build this technology for 50 % of fuel moisture content, but technology will not raise the temperature parameters of hot water. There are two differences between Mladá Boleslav heating plant and Finnish Vuosaari power plant in Helsinky, where the similar unit is already built. First of them is moisture content of fuel more than 50 %. Second one is temperature of hot water system 60 °C, however in Mladá Boleslav is at least 80 °C, sometimes it could be more than 110 °C. The decreasing of this temperature is problem because the most of heating systems were designed by current standards with temperature 80 °C.
The only possible solution is to build two steps scrubber and the waste heat utilize as preheater of hot water.
