Abstract

OBJECTIVE
To determine breed-specific reference intervals for whole blood (WB) and plasma taurine concentrations in adult, overtly healthy Cavalier King Charles Spaniels (CKCSs) and determine whether taurine concentrations differ across preclinical myxomatous mitral valve disease (MMVD) stages or between CKCSs eating diets that meet World Small Animal Veterinary Association (WSAVA) nutritional guidelines versus other diets.

ANIMALS
200 privately owned CKCSs.

PROCEDURES
Clinically healthy adult CKCSs were recruited prospectively. Diet and supplement history was collected. Dogs were staged by echocardiography using MMVD consensus guidelines. Taurine concentrations were measured in deproteinized lithium heparin WB and plasma samples with the postcolumn ninhydrin derivatization method on a dedicated amino acid analyzer.

RESULTS
There were 12 stage A (6%), 150 stage B1 (75%), and 38 stage B2 (19%) CKCSs. Seventy-eight dogs (39%) were reported by their owners to be eating diets meeting WSAVA nutritional guidelines; 116 (58%) were not. Taurine concentrations in plasma (P = .444) and WB (P = .073) were not significantly different across MMVD stages or between CKCSs eating diets meeting WSAVA nutritional guidelines versus other diets (P = .345 and P = .527, respectively). Reference intervals for WB taurine (152 to 373 µM) and plasma taurine (51 to 217 µM) concentrations in CKCSs were generated.

CLINICAL RELEVANCE
In CKCSs, taurine concentrations do not differ significantly based on preclinical MMVD stage, nor do they differ significantly based on consumption of a diet that does or does not meet WSAVA nutritional guidelines.
Semantic-Based Dynamic Service Adaptation in Context-Aware Mobile Cloud Learning

Published: September 2022

AbstractSelf-adaptable system concerns on service adaptation whenever errors persist within the system. Changes in contextual information such as networks or sensors will affect the system’s effectiveness because the service adaptation process is not comprehensively handled in those contexts. Besides, the correctness to get the most equivalence services to be substituted is limitedly being addressed from previous works. A dynamic service adaptation framework is introduced to monitor and run a reasoning control to solve these issues. Hence, this paper presents a case study to proof the dynamic service adaptation framework that leverages on semantic-based approach in a context-aware environment. The evaluation of the case study resulted in a significant difference for the effectiveness at a 95% confidence level, which can be interpreted to confirm that the framework is promising to be used in operating dynamic adaptation process in a pervasive environment.

Abstract
This study presents data on regular health monitoring of fish in the Aquatika – Freshwater Aquarium Karlovac between October 2016 and December 2019. The Aquatika Aquarium houses 85 different freshwater fish species, 31 of which are endemic in Croatia. The study included an evaluation of the results of the aquarium health monitoring programme. It determined the most common fish diseases in the aquarium (at the species and individual levels) and determined whether endemic or non-endemic freshwater fish are more susceptible to diseases and disorders. The regular health monitoring programme revealed different diseases and disorders in endemic and non-endemic fish. During the monitoring, 3104 fish specimens were analysed. The most frequent disease was ichthyophthiriasis which occurred at a similar frequency in endemic and non-endemic fish species. The results proved to be valuable for the evaluation of risks and measures to minimise the risk of the introduction and spread of pathogens in the aquarium. Preventive fish medicine is extremely important for effective aquarium management. A comprehensive health monitoring programme, including quarantine systems, control of feed and environmental parameters, along with regular fish observation, are critical for the early detection of fish diseases.
Active-clamped flyback DC-DC converter in an 800V application: Design notes and control aspects
Authors: Vračar Darko , Pejović Predrag 
Published: September 2022

Abstract
This paper presents findings for active-clamped flyback (ACF) DC-DC converter 57 W used as an auxiliary power-supply of a wireless inductive-charging system 800 V. Measurements of magnetizing and leakage inductances for three transformers demonstrated how big differences between them could be depending on chosen vendor. Comparison of simulated and measured Bode plots showed that, even when those plots were not matched, one could design a compensator that ensures stable operation. Evaluation of cross-regulation when output with low power (9.62 % of total) was regulated showed that such approach was feasible too. The switching frequency vs output-power and drain-source voltage of switch vs output-power graphs are presented for the first time. Comparison of bandwidth, phase-margin and gain-margin vsinput-power, between the ACF and conventional flyback converter were discussed too. Those quantities were changeable with load and input-voltage as expected. The conventional flyback converter in DCM has higher bandwidth than the ACF which resulted in lower phase- and gain-margins. That showed that it cannot have the same compensator as an ACF.
Model predictive control for distributed MPPT algorithm of cascaded H-bridge multilevel grid-connected PV inverters

Published: September 2022

Abstract
This paper concentrates on an algorithm with model predictive control for current and distributed MPPT for cascaded H-bridge multilevel photovoltaic (PV) inverter applications. In conventional method, in each sampling period, a discrete-time model is employed to predict the current future values for all vectors of voltage. The voltage vector will be approved if it minimizes the cost function. Because multilevel inverter has so many available voltage vectors, there is a large quantity of calculations, hence it makes difficult in implementing the normal control method. A varied control strategy that extensively decreases the calculations volume and eliminating common-mode voltage is proposed. To raise the PV modules performance and enlarge the systems power, a distributed maximum power point tracking (MPPT) control scheme for each phase of multilevel inverter is offered, that allows its DC-link voltage to be regulated separately. The recommended approach is double-checked by using a model simulated in MATLAB-Simulink software.

Published: September 2022

Abstract

Background: BNT162b2 is a widely used mRNA COVID-19 vaccine for which 8.2% of participants above the age of 56 years have reported diarrhea as an adverse event. This case report highlights the possibility of eosinophilic colitis in post-vaccination diarrhea.

Case report: A 72-year-old male patient presented with generalized colicky abdominal pain and acute diarrhea after receiving the first dose of the BNT162b2 vaccine. Laboratory examination revealed peripheral blood eosinophilia with cecal and ascending colon mucosal eosinophilia with 100–130 cells/HPF and eosinophilic cryptitis. The patient’s symptoms and eosinophilia resolved spontaneously and did not recur after the second dose of vaccination. More research is needed to confirm eosinophilic colitis as a possible vaccine adverse reaction.

Published: September 2022

Abstract
The eye tracking technique is increasingly used in the context of examining the method of processing visual information from instruments and displays located in the cockpit of an airplane. An important aspect is monitoring the pilot’s visual behavior in the most difficult phase of the flight, which is the landing of the plane. Six people participated in the research, divided into three groups according to their experience. The subjects performed three landing approaches in various weather conditions. During the study, the visual behavior of the participants was recorded using the Pupil Invisible eye tracker. Based on the analysis of heatmaps and areas of interest, differences in the distribution and number of fixations in the visual field between pilots with different aviation experience were shown.

Published: September 2022

Abstract
Since Poland’s accession to the European Union in 2004, a steady increase in transaction prices of agricultural property has been observed. Also in other countries, mainly in Eastern and Central Europe, there has been an ongoing increase in the prices of agricultural land. The situation on the agricultural land market is influenced not only by the market mechanisms, but also by the political decisions, including restrictions in the turnover of land properties. The purpose of the study is to analyze the agricultural land market in Poland and to determine the relationship of average land prices for housing, service and industrial purposes against the average prices of agricultural land in 2004-2019. In the course of the study, price changes on the discussed market were assessed, and forecasts and simulations concerning the prices of agricultural properties and land intended for selected investment purposes were prepared. It was established that the increase in agricultural property prices over the recent dozen or so years is inadequate to the increase in the average gross salary in Poland and the average income from work at individual farms. However, the increase in prices is almost parallel to the increase in average transaction prices of property intended for housing purposes.
“German Pamphlets, Russian Chronicles, and Ivan the Terrible”
Authors: Halperin Charles J. 
Published: September 2022

Abstract
Many historians have questioned the accuracy of the “Tale of Ivan IV’s Campaign against Novgorod in 1570.” Cornelia Soldat now expands that critical approach to the “Tale” by arguing that it derives from German pamphlets published a century earlier. She relies upon the congruence of macro- and micro-structures to demonstrate textual influence without textual borrowing. Given the absence of Muscovite manuscripts of the “Tale” between 1570 and the second half of the seventeenth century, the composers of the “Tale” “must have” relied upon foreign sources about the raid, because no domestic sources existed. Her analysis is certainly possible, but it elides a number of issues about the transmission and translation into Russian of the German pamphlets. Reliable contemporary Muscovite sources tells us more about the “real” raid than Soldat allows. It is equally possible that the “Tale” derives from circulating native oral legends. However, the methodological and evidentiary issues Soldat raises are serious and deserve further discussion.
Making an Anti-Hero or Describing a Tyrant? Postmodernism and Ivan the Terrible
Authors: Filyushkin Alexander 
Published: September 2022

Abstract
Historiography of the study of Ivan the Terrible’s times contains many examples of demystification attempts: E. Keenan declared the correspondence between Ivan the Terrible and Andrey Kurbsky to be apocrypha, Anthony Grobovsky exposed the ‘Chosen Rada’, Mikhail Krom unmasked the time of ‘boyar rule’. Cornelia Soldat suggests revising the history of the ‘massacre of Novgorod’ in 1570. She believes it to be a product of a ‘literary game’. The story of the destruction of Novgorod first appeared in the German Flying Leaf in 1570 and Alexander Guagnini’s Chronicle in 1578. It was a product of European political discourse. The Novgorod Chronicles borrowed that story from Guagnini’s Chronicle in the late 17th century. However, this hypothesis lacks sufficient proof. Independent evidence exists: The Solovetsky Chronicle of the 16th century. According to Soldat, the reports from The Novgorod Uvarov Chronicle date back to the late 16t–early 17th (about 1606) centuries, rather than to the 17th century. The main argument against her concept is the confirmation in independent sources and documents of the death of many people, while the circumstances of the repression or death point to Novgorod and 1570. The Novgorod chronicles contain no evidence of text borrowings from German or Polish sources. There is no proven textual similarity between them. The story of the ‘massacre of Novgorod’ evolved in the Novgorod’s urban legends. This would have been hardly possible, if this story had been of a purely bookish, literary origin. Therefore, Cornelia Soldat’s attempt to demystify the history of the ‘massacre of Novgorod’ in 1570 cannot be considered convincing.

Herbal medicines are an important and growing part of International pharmacopeia. Research and testing enhance our understanding of their medical properties, making them a safer alternative or preferable option to allopathic medication. Plant-derived pharmaceuticals are gaining popularity due to the belief that "green medicine" is safer and more trustworthy than expensive synthetic drugs. This study aimed to evaluate the antimicrobial and anticancer potential of the methanolic leaf extract of Artemisia absinthium against human lung cancer A549 cell line by well diffusion method and MTT assay, respectively. The A. absinthium leaf extract showed the highest activity against Enterococcus faecalis (20 ± 0.7 mm), and Escherichia coli (18 ± 0.8 mm), followed by Pseudomonas aeruginosa (16 ± 0.6 mm), Candida albicans (14 ± 0.9 mm) and Staphylococcus aureus (13 ± 0.8 mm), with MIC values 128, 128, 128, 256 and 256 µg/mL respectively. The methanolic extract of A. absinthium showed significant (p ≤ 0.05) cytotoxicity against the A549 cancer cell line with an IC50 value of 36.8 µg/mL. The present study's findings give strong evidence for using the methanolic leaf extract of A. absinthium as an effective ethnomedicinal agent and a possible candidate for treating various human diseases and a potent bioactive agent in anticancer medications.

Biochar has gained attention in agricultural studies due to its ability to ameliorate soil conditions. However, due to its low nutrient content, positive effects on plant growth are generally only observed if combined with mineral fertilizers or manures. The study aimed to test the hypothesis that biochar used to treat domestic wastewater can become enriched with nutrients and subsequently serve as a better soil amendment. The impact of the application of biochar used as substrate in a filter for domestic wastewater treatment (TB) on the growth of lettuce (Lactuca sativa var. crispa) plant was evaluated. Its effect on plant growth was compared to pure biochar (BC) using bare soil as a control. The biochars were applied with and without fertilizer using 3 biochar application rates (10, 20 and 30 t/ha). Results showed that biochar does not become enriched after wastewater purification in the short run. Instead, there was a reduction in the mineral composition, available phosphorus and pH in TB compared to BC. Only the BC treatments were significantly different (p=0.001) from the control. However, higher biomass production at 30 t/ha was observed in BC (+322%) and TB (+142%), compared with the unfertilized control. There were no significant differences in biomass production between the biochar and control treatments for application rates below 30 t/ha. Fertilization significantly (p=0.024) improved biomass production with the BC30+F treatments demonstrating the highest performance (+315%) compared to the fertilized control.

BackgroundThe impact of COVID-19 on the outcome of patients with MI has not been studied widely. We aimed to evaluate the relationship between concomitant COVID-19 and the clinical course of patients admitted due to acute myocardial infarction (MI).MethodsThere was a comparison of retrospective data between patients with MI who were qualified for coronary angiography with concomitant COVID-19 and control group of patients treated for MI in the preceding year before the onset of the pandemic. In-hospital clinical data and the incidence of death from any cause on 30 days were obtained.ResultsData of 39 MI patients with concomitant COVID-19 (COVID-19 MI) and 196 MI patients without COVID-19 in pre-pandemic era (non-COVID-19 MI) were assessed. Compared with non-COVID-19 MI, COVID-19 MI was in a more severe clinical state on admission (lower systolic blood pressure: 128.51 ± 19.76 vs. 141.11 ± 32.47 mmHg, p = 0.024), higher: respiratory rate [median (interquartile range), 16 (14–18) vs. 12 (12–14)/min, p &lt; 0.001], GRACE score (178.50 ± 46.46 vs. 161.23 ± 49.74, p = 0.041), percentage of prolonged (&gt;24 h) time since MI symptoms onset to coronary intervention (35.9 vs. 15.3%; p = 0.004), and cardiovascular drugs were prescribed less frequently (beta-blockers: 64.1 vs. 92.8%, p = 0.009), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers: 61.5 vs. 81.1%, p &lt; 0.001, statins: 71.8 vs. 94.4%, p &lt; 0.001). Concomitant COVID-19 was associated with seven-fold increased risk of 30-day mortality (HR 7.117; 95% CI: 2.79–18.14; p &lt; 0.001).ConclusionPatients admitted due to MI with COVID-19 have an increased 30-day mortality. Efforts should be focused on infection prevention and implementation of optimal management to improve the outcomes in those patients.
