Published: October 2022

Global warming and climate change have contributed to the rise of weather extremes. Severe drought and soil salinization increase because of rising temperatures. Economically important crop production and plant growth and development are hindered when facing various abiotic stresses. Plant endophytic bacteria live inside host plants without causing visible harm and can be isolated from surface-sterilized plant tissues. Using plant endophytic bacteria to stimulate plant growth and increase environmental stress tolerance has become an alternative approach besides using the traditional breeding and genetically modifying approaches to select or create new crop types resistant to different environmental stresses. The plant endophytic bacterium, Priestia megaterium (previously known as Bacillus megaterium) strain BP-R2, was isolated from the surface-sterilized root tissues of the salt marsh halophyte Bolboschoenus planiculmis. The bacteria strain BP-R2 showed high tolerance to different sodium chloride (NaCl) concentrations and produced the auxin plant hormone, indole acetic acid (IAA), under various tested growth conditions. Inoculation of Arabidopsis and pak choi (Brassica rapa L. R. Chinensis Group) plants with the strain BP-R2 greatly enhanced different growth parameters of the host plants under normal and salt and drought stress conditions compared to that of the mock-inoculated plants. Furthermore, the hydrogen peroxide (H2O2) content, electrolyte leakage (EL), and malondialdehyde (MDA) concentration accumulated less in the BP-R2-inoculated plants than in the mock-inoculated control plants under salt and drought stresses. In summary, the plant endophytic bacterium strain BP-R2 increased host plant growth and stress tolerance to salt and drought conditions.

Rotaviruses (RV) are the leading cause of gastroenteritis in infants, young children, and adults, responsible for serious disease burden. In the period 2012–2018, a cross-sectional study was conducted using stool samples collected from patients with acute gastroenteritis from Vojvodina, Serbia. We described age and gender distribution, as well as seasonal patterns of RV prevalence. Out of 1853 included stool samples, RV was detected in 29%. Hospitalized children between 1–2 years old were especially affected by RV infection (45%). The highest prevalence of infection was observed during the colder, winter/spring months. We compared sequenced representative G and P genotypes circulating in Serbia with vaccine strains and determined their genetic similarity. Genotype combination G2P[4] was the most prevalent (34.6%), followed by G2P[8] (24.1%) and G1P[8] (21.1%). Given that several epitopes were conserved, neutralization motifs among circulating strains can be characterized as sufficiently matching vaccine strains Rotarix™ and RotaTeq™, but existing antigenic disparities should not be overlooked. The present results contribute to a better insight into the prevalence of rotavirus infection in our region and point out the need for epidemiological surveillance of rotaviruses before the introduction of vaccines. These data can help formulate future vaccine strategies in Serbia.

Authors: Aspromonte Juan , Lancioni Carlina , Purcaro Giorgia
Published: October 2022

Due to their extensive use and the globalized commerce of agricultural goods, pesticides have become a global concern. Despite the undoubtful advantages of their use in agricultural practices, their misuse is a threat to the environment and human health. Their analysis in environmental samples and in food products continues to gain interest in the analytical chemistry community as they are challenging matrices, and legal concentration limits are particularly low (in the order of ppb). In particular, the use of solid-phase microextraction (SPME) has gained special attention in this field thanks to its potential to minimize the matrix effect, while enriching its concentration, allowing very low limits of detection, and without the need of a large amount of solvents or lengthy procedures. Moreover, its combination with gas chromatography (GC) can be easily automated, making it a very interesting approach for routine analysis. In this review, advances and analytical strategies for the use of SPME coupled with GC are discussed and compared for the analysis of pesticides in food and environmental samples, hopefully encouraging its further development and routine application in this field.

This study aimed to detect the virulent Salmonella serovars (including ESBLs producing) isolated from broiler chickens and humans. Three hundred broilers and sixty human fecal samples were bacteriologically examined. Thirty (10%) and fourteen (23.4%) Salmonella isolates were recovered from broiler and human samples, respectively. The most predominant serovar was S. enteritidis and S. typhimurium. All Salmonella isolates were confirmed by conventional PCR-based invA and ompA genes. Multidrug resistant (MDR) isolates were screened for the detection of adrA and csgD biofilm-associated genes, which were found in all isolated serovars except one S. typhimurium and 2 S. infantis of chicken isolates that were devoid of the adrA gene. Moreover, MDR isolates were screened for detection of seven resistance genes including ESBLs and other classes of resistance genes. Chicken isolates harbored blaTEM, int1, blaCTX and qnrS genes as 100, 27.8, 11.1 and 11.1%, respectively, while all human isolates harbored blaTEM, int1 and int3 genes. The genetic correlations between virulent Salmonella serovars (including antimicrobial resistance) avian and human origins were compared. In conclusion, the high prevalence of virulent ESBL producing Salmonella serovars in broilers and humans with genetic correlations between them might be zoonotic and public health hazards.
Combined Effect of Ultrasound and Microwave Power in Tangerine Juice Processing: Bioactive Compounds, Amino Acids, Minerals, and Pathogens
Authors: Demirok Nazan Tokatlı , Yıkmış Seydi
Published: October 2022

The inhibition of Escherichia coli ATCC 25922 (E. coli), Staphylococcus aureus ATCC6538 (S. aureus), Salmonella Enteritidis ATCC 13076 (S. Enteritidis), and Listeria monocytogenes DSM12464 (L. monocytogenes) is one of the main aims of the food industry. This study was the first in which the use of ultrasound and microwave power were applied to optimize the values of the bioactive components, amino acids, and mineral compositions of tangerine juice and to inhibit Escherichia coli, Staphylococcus aureus, Salmonella Enteritidis, and Listeria monocytogenes. The response surface methodology (RSM) was used to describe the inactivation kinetics, and the effects of ultrasound treatment time (X1: 12–20 min), ultrasound amplitude (X2:60–100%), microwave treatment time (X3: 30–40 s), and microwave power (X4:200–700 W). The optimum parameters applied to a 5-log reduction in E. coli were determined as ultrasound (12 min, 60%) and microwave (34 s, 700 W). The optimum condition ultrasound–microwave treatment was highly effective in tangerine juice, achieving up to 5.27, 5.12, and 7.19 log reductions for S. aureus, S. Enteritidis, and L. monocytogenes, respectively. Ultrasound–microwave treatment increased the total phenolic compounds and total amino acids. While Cu, K, Mg, and Na contents were increased, Fe and Ca contents were lower in the UM-TJ (ultrasound–microwave-treated tangerine juice) sample. In this case, significant differences were detected in the color values of ultrasound–microwave-treated tangerine juice (UM-TJ) (p < 0.05). The results of this study showed that ultrasound–microwave treatment is a potential alternative processing and preservation technique for tangerine juice, resulting in no significant quality depreciation.
Karl Barth, Memory, and the Nazi Past: Confronting the Question of German Guilt
Authors: Skiles William S.
Published: October 2022

This article examines Karl Barth’s confrontation with the Nazi past in his post-war occasional writings and speeches from 1945 to 1950. My thesis is that as early as January 1945, months before the end of the war in Europe, Barth publicly argued the collective guilt of the German people yet sought not to examine this guilt or demand a “collective punishment”—for the crimes were so great and far-reaching into German society, the responsibility too entangled, that it would be impossible to fully understand or appreciate the crimes committed during this period. Instead, Barth wished simply to acknowledge this guilt, encourage the German people to accept it, and continue with the monumental task of reconstructing Germany. Barth’s post-war work proved tremendously influential in challenging the history of the Protestant churches’ uncritical stand in obedience to the state.

Published: October 2022

The use of Sensors and Actuators is ubiquitous in an industrial environment. The advent of the Industrial Internet-of-Things (IIoT) and the 4th industrial revolution demands new, more intelligent and more efficient ways to be able to connect, read and control transducers at the plant floor level. Newer control and data science techniques also largely benefit from structured information endpoints available at the edge of the network. The IEEE 1451 standard presents architecture and methodology to solve these problems with the usage of smart transducers, introducing into edge devices concepts such as self-identification and standardization of data communication. In this work, a transducer interface module is developed using the IEEE 1451 standard focused on flexibility, ease of integration and plug-and-play features. Furthermore, a system architecture, based on IEEE 1451.0 is presented, and development and implementation features are explained. This system is then released as an open-source platform to help and motivate the usage of smart transducer systems. At last, the system is tested, results are collected, and a methodology and metrics are defined for comparison between different smart transducer systems.

Published: October 2022

Healthcare digitalization requires effective applications of human sensors, when various parameters of the human body are instantly monitored in everyday life due to the Internet of Things (IoT). In particular, machine learning (ML) sensors for the prompt diagnosis of COVID-19 are an important option for IoT application in healthcare and ambient assisted living (AAL). Determining a COVID-19 infected status with various diagnostic tests and imaging results is costly and time-consuming. This study provides a fast, reliable and cost-effective alternative tool for the diagnosis of COVID-19 based on the routine blood values (RBVs) measured at admission. The dataset of the study consists of a total of 5296 patients with the same number of negative and positive COVID-19 test results and 51 routine blood values. In this study, 13 popular classifier machine learning models and the LogNNet neural network model were exanimated. The most successful classifier model in terms of time and accuracy in the detection of the disease was the histogram-based gradient boosting (HGB) (accuracy: 100%, time: 6.39 sec). The HGB classifier identified the 11 most important features (LDL, cholesterol, HDL-C, MCHC, triglyceride, amylase, UA, LDH, CK-MB, ALP and MCH) to detect the disease with 100% accuracy. In addition, the importance of single, double and triple combinations of these features in the diagnosis of the disease was discussed. We propose to use these 11 features and their binary combinations as important biomarkers for ML sensors in the diagnosis of the disease, supporting edge computing on Arduino and cloud IoT service.

Authors: Gadhavi Bhargav , Golnaraghi Farid , Bahreyni Behraad
Published: October 2022

This paper presents a single-axis angular rate sensor that is robust to variations in its operating voltage and frequencies. The sensor is developed to overcome the shortcomings of conventional mode-matched Micromachined Vibratory Gyroscopes in open loop operations, namely narrow frequency bandwidths and unstable scale factors. The developed sensor utilizes inherent forcing and inertial nonlinearities from electrostatic forces and fabrication imperfections to auto-parametrically excite the sense mode via 2:1 auto-parametric resonance, which yields a broader bandwidth frequency response for the sensor’s sense mode. The experimental results demonstrated −3 dB frequency bandwidth of 500 Hz, a scale factor of 50 μV/°/s, and a dynamic range of ±330°/s.

Published: October 2022

The lower limb rehabilitation robot is a typical man-machine coupling system. Aiming at the problems of insufficient physiological information and unsatisfactory safety performance in the compliance control strategy for the lower limb rehabilitation robot during passive training, this study developed a surface electromyography-based gain-tuned compliance control (EGCC) strategy for the lower limb rehabilitation robot. First, the mapping function relationship between the normalized surface electromyography (sEMG) signal and the gain parameter was established and an overall EGCC strategy proposed. Next, the EGCC strategy without sEMG information was simulated and analyzed. The effects of the impedance control parameters on the position correction amount were studied, and the change rules of the robot end trajectory, man-machine contact force, and position correction amount analyzed in different training modes. Then, the sEMG signal acquisition and feature analysis of target muscle groups under different training modes were carried out. Finally, based on the lower limb rehabilitation robot control system, the influence of normalized sEMG threshold on the robot end trajectory and gain parameters under different training modes was experimentally studied. The simulation and experimental results show that the adoption of the EGCC strategy can significantly enhance the compliance of the robot end-effector by detecting the sEMG signal and improve the safety of the robot in different training modes, indicating the EGCC strategy has good application prospects in the rehabilitation robot field.

SUTO-Solar Through-Turbulence Open Image Dataset
Authors: Popowicz Adam , Orlov Valeri
Published: October 2022

Imaging through turbulence has been the subject of many research papers in a variety of fields, including defence, astronomy, earth observations, and medicine. The main goal of such research is usually to recover the original, undisturbed image, in which the impact of spatially dependent blurring induced by the phase modulation of the light wavefront is removed. The number of turbulence-disturbed image databases available online is small, and the datasets usually contain repeating types of ground objects (cars, buildings, ships, chessboard patterns). In this article, we present a database of solar images in widely varying turbulence conditions obtained from the SUTO-Solar patrol station recorded over a period of more than a year. The dataset contains image sequences of distinctive yet randomly selected fragments of the solar chromosphere and photosphere. Reference images have been provided with the data using computationally intensive image recovery with the latest multiframe blind deconvolution technique, which is widely accepted in solar imaging. The presented dataset will be extended in the next few years as new image sequences are routinely acquired each sunny day at the SUTO-Solar station.
Preliminary Evidence of EEG Connectivity Changes during Self-Objectification of Workers

Published: October 2022

Economic objectification is a form of dehumanization in which workers are treated as tools for enhancing productivity. It can lead to self-objectification in the workplace, which is when people perceive themselves as instruments for work. This can cause burnout, emotional drain, and a modification of self-perception that involves a loss of human attributes such as emotions and reasoning while focusing on others’ perspectives for evaluating the self. Research on workers self-objectification has mainly analyzed the consequences of this process without exploring the brain activity that underlies the individual’s experiences of self-objectification. Thus, this project explores the electroencephalographic (EEG) changes that occur in participants during an economic objectifying task that resembled a job in an online store. After the task, a self-objectification questionnaire was applied and its resulting index was used to label the participants as self-objectified or non-self-objectified. The changes over time in EEG event-related synchronization (ERS) and partial directed coherence (PDC) were calculated and compared between the self-objectification groups. The results show that the main differences between the groups in ERS and PDC occurred in the beta and gamma frequencies, but only the PDC results correlated with the self-objectification group. These results provide information for further understanding workers’ self-objectification. These EEG changes could indicate that economic self-objectification is associated with changes in vigilance, boredom, and mind-wandering.

Published: October 2022

In experimental settings, replacing old wood stoves with new wood stoves results in reduced personal exposure to household air pollution. We tested this assumption by measuring PM2.5 and levoglucosan concentrations inside homes and correlated them with wood stove age. Methods: Thirty homes in the Albuquerque, NM area were monitored over a seven-day period using in-home particulate monitors placed in a common living area during the winter months. Real-time aerosol monitoring was performed, and filter samples were analyzed gravimetrically to calculate PM2.5 concentrations and chemically to determine concentrations of levoglucosan. A linear regression model with backward stepwise elimination was performed to determine the factors that would predict household air pollution measures. Results: In this sample, 73.3% of the households used wood as their primary source of heating, and 60% burned daily or almost daily. The mean burn time over the test week was 50 ± 38 h, and only one household burned wood 24/day (168 h). The average PM2.5 concentration (standard deviation) for the 30 homes during the seven-day period was 34.6 µg/m3 (41.3 µg/m3), and median (min, max) values were 15.5 µg/m3 (7.3 µg/m3, 193 µg/m3). Average PM2.5 concentrations in 30 homes ranged from 0–15 μg/m3 to >100 μg/m3. Maximum PM2.5 concentrations ranged from 100–200 μg/m3 to >3000 μg/m3. The levoglucosan levels showed a linear correlation with the total PM2.5 collected by the filters (R2 = 0.92). However, neither mean nor peak PM2.5 nor levoglucosan levels were correlated with the age (10.85 ± 8.54 years) of the wood stove (R2 ≤ 0.07, p > 0.23). The final adjusted linear regression model showed that average PM2.5 was associated with reports of cleaning the flue with a beta estimate of 35.56 (3.47–67.65) and R2 = 0.16 (p = 0.04). Discussion: Cleaning the flue and not the wood stove age was associated with household air pollution indices. Education on wood stove maintenance and safe burning practices may be more important in reducing household air pollution than the purchase of new stoves.
Honey Bee Pathogen Prevalence and Interactions within the Marmara Region of Turkey
Authors: Mayack Christopher , Hakanoğlu Haşim
Published: October 2022

Beekeeping has yet to reach its full potential in terms of productivity in Turkey where it has a relatively large role in the economy. Poor colony health is suspected to be the reason for this, but comprehensive disease monitoring programs are lacking to support this notion. We sampled a total of 115 colonies across five different apiaries throughout the Marmara region of Turkey and screened for all of the major bee pathogens using PCR and RNA-seq methods. We found that Varroa mites are more prevalent in comparison to Nosema infections. The pathogens ABPV, DWV, KV, and VDV1 are near 100% prevalent and are the most abundant across all locations, which are known to be vectored by the Varroa mite. We therefore suspect that controlling Varroa mites will be key for improving bee health in Turkey moving forward. We also documented significant interactions between DWV, KV, and VDV1, which may explain how the more virulent strain of the virus becomes abundant. ABPV had a positive interaction with VDV1, thereby possibly facilitating this more virulent viral strain, but a negative interaction with Nosema ceranae. Therefore, these complex pathogen interactions should be taken into consideration in the future to improve bee health.

Published: October 2022

Porcine parvovirus (PPV) disease is a worldwide spread animal disease with high infection rate and serious impact on meat economy causing significant losses in livestock production. The purpose of this paper is to investigate and analyze the regional seroprevalence of PPV in Tibetan pigs in Tibet and evaluate risk factors related to the disease. A total of 356 serum samples of Tibetan pigs were collected from four counties and districts in Tibet, and anti-PPV antibodies were detected by using a commercial competitive ELISA. Our results show a seroprevalence of 91.01% (324 serum samples were found to be positive for anti-PPV antibodies). The positive rate among different district was 100%, 96.55%, 93.68% and 72.83%, respectively in the Mainling County, in Bayi district, Nang County and Bomê County. We found significant differences between different age and gender groups; particularly female animals show a seroprevalence of 96.03% while the males only 83.46%. From the perspective of the growth stage, our results indicate that subadults show a seroprevalence significative higher than other age groups (100%). This study describes for the first time the PPV seroprevalence among Tibetan pigs characterizing risk factors involved in its transmission and providing information to be taken into account for eventual surveillance or eradication plans.

Sports activities have a positive effect on health, the assimilation of knowledge by students. In order period, KEC had significantly lower values than before taking the product. This testified to the lower costs of the body for the movement of blood volume in the vascular bed, which means that the body was more heavily saturated with substances for its restoration. A tendency towards an increase in the Kerdo vegetative index was determined, which indicated an increase in nutrient anabolism. The research actualizes the need for medical and pedagogical support of sports activities among students to achieve a training effect and a positive impact on their health.
Transgenesis and its Applications in Aquaculture
Authors: KHOO HONG WOO
Published: October 2022

The main transgenesis techniques which are successful in introducing exogenous genes into fish are microinjection and electroporation. Genes are introduced into one-celled embryos as well as oocytes. Microinjection is the more established method but it depends on individual treatment of the egg. Electroporation, on the other hand, is a mass method only recently shown to be effective. Other transfer techniques, such as those using sperms, liposomes, microprojectiles, embryonic stem cells and retroviruses as the vehicle, have also been reported to produce transgenic fish. Most transgenic experiments are at present conducted on finfish, and hardly any on other aquatic organisms like invertebrates except for sea urchins and, more recently, abalones. The genes with potential transgenic applications in aquaculture which have been shown to be effective in fish are the growth hormone and the anti-freeze genes. The potentials of manipulating reproduction, sex, coloration, disease resistance and other phenotypes are discussed. Studies on eco­logical, social and ethical issues of transgenic research and applications to animals in general and to fish in particular, are also reviewed.
Impact of Improved Aquaculture Technologies: Results of an Extension Program on the Farming Systems of Bangladesh
Authors: AHMED M.
Published: October 2022

The paper discusses the results of a new strategy for extension of improved fish culture practices within the existing farming systems of Bangladesh. Implemented in a few selected village units, the main objective of the extension program was to assist farmers to adopt fish culture in small waterbodies (ponds/ditches). The extension program provided farmers with services such as farm visits, technical advice, training and demonstration for three main technologies: 1) poly culture of Indian, Chinese and common carps; 2) Nile tilapia ( Oreochromis niloticus) culture; and 3) silver barb (Puntius gonionotus) culture. Results show that the farmers responded positively with respect to stocking density, species ratio and input use, although these were not as per recommendations. Nevertheless, by adopting new aquaculture practices, the farmers were able to produce more fish (9.89 kg·40 m·2) than the baseline production (2.2 kg·40 m-2), as well as earn a higher income per unit of pond area. Average net profit-cost ratio was estimated at 2.44. The study concluded that targetting farmers who already have waterbodies (ponds and ditches) through extension services can push up aquaculture production and benefits significantly. Fish disease and floods were identified as major risk factors.

Published: October 2022

Apparent protein digestibility (%) of some low-cost feedstuffs is reported for fingerling Indian major carps, Labeo rohita, Cirrhinus mrigala and Calla cat/a. Significant differences (t<0.05) were observed in the digestibility of feedstuffs. Among the feedstuffs tested, protein from plant sources showed higher digestibility for the three carp species. The highest digestibility (93-94%) was noted for soybean oil cake. Values for other plant origin feedstuffs ranged between 81 and 90%. Digest­ibility of proteins from fish meal and slaughterhouse offal was relatively low (74-76%).
Effect of Varying Dietary Lipid Levels on Growth, Feed Conversion, Nutrient Retention and Carcass Composition of Fingerling Catfish, Heteropneustes fossilis
Authors: ANWAR M. FAROOQ , JAFRI A.K.
Published: October 2022

Casein-gelatin based purified diets ( 40% CP, 18 kJ·g·1 GE) with graded levels (3,5,7,9,11 and 13%) of lipid were fed to fingerling Heteropneustes fossilis to Investigate changes in growth, feed conversion, nutrient retention and carcass composition. Fish stocked in triplicate sets of 15 fish each, in 70 I flow-through (1.0-1.5 l ·min-1 ) type polyvinyl circular troughs, were fed diets at the rate of 4% body weight-day-1• Over the six-week growth trial, maximum gain in live weight (194%), specific growth rate (2.57%), protein efficiency ratio (1.76) and best feed gain ratio (1.44) were noted in fish at 7% lipid intake. Moisture, crude protein, fat and gross energy contents of carcass were significantly (P<0.05) affected by diet. Although carcass protein and percent protein retention increased up to 7% dietary lipid level, dry matter, crude fat, gross energy and percent GE retention registered a constant increase with dietary lipid levels. The tendency of fat deposition at each incremental dietary lipid level was found to be more pronounced in viscera than in muscle. The hepatosomatic index was not correlated to dietary lipid levels. It was concluded that H. fossilis requires a level of 7% lipid as an energy source in 40% CP diet, with 18.2±0.21 kJ·g-1 of gross energy and a carbohydrate-to-lipid ratio of about 5 for maximum utilization and growth.

Published: October 2022

Seasonal changes in structure or demersal fish assemblages or the Yellow Sea are studied by means or cluster analysis based on bottom trawl surveys from March 1985 to January I 986. Simple discriminate analysis is used to test for significant differences in environmental character­istics among sampling station groups which show that species composition and biomass in each group and season are associated with bottom water temperature. The cold water mass in the central Yellow Sea plays an important role in distribution of fish One to three absolutely dominant species in each group usually characterize the grouping area, accounting for more than 40% of the total catch. The similarity values or species composition between seasons are relatively low, all less than 50%.
Supplemental Effects of Euglena gracilis in a Casein Diet for Penaeus japonicus
Authors: HAYASHI M.
Published: October 2022

Feeding experiments with larvae and juveniles of prawn, Penaeus japonicus, were conducted to evaluate the supplemental effects of Euglena gracilis cells in a casein diet. All diets containing Euglena cells had a comparable dietary value to that of the casein diet Supplementation with 13.25% Euglena cells in a casein diet improved growth of larvae, and growth and feed conversion efficiency of juveniles. Enriching the fatty acid composition in Euglena with eicosapentaenoic or docosahexaenoic acid gave no further improvement on growth or survival of the prawn. The experiments suggest that Euglena cells contain a growth-promoting factor for the prawn in addition to essential amino acids.

Published: October 2022

Sperm or Mekong giant catfish (Pangasius gigas; formerly Pangasianodon gigas) were cryopreserved in 5 or 9% dimethyl sulfoxide (DMSO) in bicarbonate buffer (BCB) or calcium-free Hanks' balanced salt solution (C-F HBSS) at different cooling rates (-5, -12, -22 or -120 "C·min"1) and stored in liquid nitrogen for 3-4 months. Pooled ova of three female Gunther's walking catfish (Clarias macrocephalus) were inseminated with cryopreserved semen or Mekong giant catfish and fresh semen of the walking catfish (control). There was no significant difference in fertility of sperm cryopreserved in the two extenders. Best results were obtained when sperm were cryopreserved in 9% DMSO in either extender in 5 ml cryotubes and frozen at -12 "C•min-1• The percentage or fertilization was 65-66% (actual) and 73-74% (control).

This research is motivated by the student's interest in learning in developing the potential for mathematical understanding which is still low. The purpose of this study was to determine the relationship between learning frequency and students' mathematical abilities. This study uses a survey research design with a descriptive correlational method. The data in this study are the results of a study of documentation and questionnaires conducted on students in mathematics. Based on the results of the correlation hypothesis test, the relationship was 36.7%. It can be concluded that the frequency of learning with the mathematical ability of class X science students has a positive weak correlation. This means that there is a relationship between the frequency of learning with the mathematical ability of class X science students. Where if the frequency of student learning is high, the higher the student's mathematical ability.

We study the model of interregional trade under monopolistic competition of producers. We obtain a local comparative statics of symmetric social optimality with respect to transport costs. Particular attention is paid to situations of free trade and autarky. For the case of two regions, counterintuitive results we obtain that (1) with low transport costs in one of the regions, public welfare can either increase or decrease; (2) when transport costs are high, trade liberalization worsens public welfare in one region and improves it in another.

Published: October 2022

Introdução. O Controle Direcionado de Temperatura é utilizado, principalmente, para reduzir lesões de reperfusão em pacientes vítimas de parada cardíaca internados em Unidade de Terapia Intensiva que permanecem comatosos após a ressuscitação e o retorno da circulação espontânea. Objetivo. Discutir a avaliação do prognóstico de pacientes comatosos que foram submetidos ao Controle Direcionado de Temperatura após uma parada cardiorrespiratória, haja vista que esta abordagem terapêutica poderia alterar tanto a acurácia quanto os valores de corte dos parâmetros normalmente utilizados. Método. Trata-se de revisão integrativa com abordagem qualitativa. Na busca, foram utilizadas as palavras-chave “ICU”, “induced hypothermia”, “Targeted Temperature Management”, “cooling”, “cardiac arrest” e “prognosis”. A análise incluiu estudos primários publicados a partir de 2010 envolvendo diferentes testes clínicos e laboratoriais prognósticos nesse contexto, verificando suas aplicabilidades práticas atuais. Resultados. A terapia com controle direcionado de temperatura de fato interfere na validade dos testes atualmente empregados e nos seus respectivos parâmetros de referência.  Conclusões. Torna-se imprescindível uma avaliação combinada de diferentes exames (multiparamétrica), bem como realização de testes clínicos randomizados e estudos em maiores escalas, de forma a guiar a criação de uma diretriz clara e atualizada para esse grupo específico de pacientes.

Key Points

Cardiovascular disease—a key driver of morbidity in CKD—is common in patients with autosomal dominant polycystic kidney disease (ADPKD).

Pathologic echocardiography findings, including valvular defects, aortic root dilation, and hypertrophy, are found in most patients with ADPKD.

These findings correlate with parameters indicating disease progression in ADPKD. Echocardiography should be offered to all patients with ADPKD.

Background

ADPKD is the most common monogenetic kidney disease and results in kidney failure in >75% of affected individuals. As a systemic disorder, ADPKD is associated with a variety of extrarenal manifestations, including cardiac manifestations, that affect the majority of patients. We characterized the cardiac involvement in patients with ADPKD from the German AD(H)PKD registry and compared them with kidney donor candidates as controls.

Methods

In this single-center cohort study, we evaluated 141 patients with ADPKD (44.17±11.23 years) from the German AD(H)PKD registry and 60 kidney donor candidates (55.08±10.21 years). All patients underwent clinical examination, abdominal MRI, and transthoracic echocardiography.

Results

Of the patients with ADPKD, 65% showed hypertrophy of the left ventricle (as defined by an end-diastolic interventricular septal wall thickness [IVSd] >10 mm) compared with 55% in control patients. Mitral regurgitation was the most common finding among 54% of patients with ADPKD who exhibited valvular dysfunction, albeit mild in most patients. Interestingly, left ventricular ejection fraction (LV-EF) differed significantly between both groups, with higher values in patients with ADPKD (64%±6% versus 60%±6%), whereas other parameters, including IVSd, left ventricular end-diastolic diameter (LVEDD), tricuspid annular plane systolic excursion (TAPSE), and pressure gradients across the aortic and tricuspid valve were similar between groups. Correlations of echocardiographic parameters with markers of disease progression revealed statistically significant associations for aortic root diameter (P=0.01), the pressure gradient across the aortic valve (AV dPmax; P=0.0003), and IVSd (P=0.0001), indicating rapid kidney disease progression may also be associated with cardiac findings.

Conclusion

Cardiovascular abnormalities are prevalent in patients with ADPKD. Considering the importance of cardiovascular disease for outcomes in CKD, early management and possibly prevention are important goals of any treatment scheme. Consequently, echocardiography should be offered to all patients with ADPKD in routine management.

Published: October 2022

This article aims to analyze the dyslexia that is a learning disorder, and as such points to the dif-ficulties that the individual presents during the development process of learning to read and write, important assumptions for the mastery of the Portuguese language. It is known that for an adequate treatment of the disorder, professionals from various areas must be involved in this process, such as speech therapists, psychopedagogists, neurologists, ENT specialists, etc. Anoth-er important professional, who must be involved in the process of acquiring the knowledge and skills necessary for the learning of dyslexic children, is the teacher. Therefore, directing the theme to the educational universe, we agree that the school has the responsibility to implement strategies that collaborate in the intellectual development of the child who has dyslexia. For this reason, the present work investigated through bibliographic research and analysis of reports on dyslexia, highlighting its characteristics and possible causes.
Student perceptions of instructor mindset are associated with undergraduate academic performance

Published: October 2022

A growth mindset of intelligence reflects the belief that intelligence is malleable. We propose that how students perceive the mindset beliefs of their professors—through verbal and nonverbal cues present in the classroom—might be a strong predictor of student academic performance. Survey and institutional data from a university-wide sample of 6,060 undergraduate students and 110 instructors across various disciplines and learning modalities revealed that students’ perceptions of instructor mindset, but not their own mindset or instructor-reported mindset, were significantly associated with end-of-semester grades. Instead of trying to shift student or instructor mindset beliefs, interventions for enhancing academic performance could more effectively target situational cues—such as instructor language about ability and classroom practices—and how students understand and interpret these signals.
MULLA HADI SABZAWARI AS A LEADING LATER SADRIAN PHILOSOPHER: REVISITING HIS LIFE AND WORKS
Authors: Febrian Rizky
Published: October 2022

The purpose of this article is to revisit the life and significant works of the nineteenth-century Persian philosopher Mulla Hadi Sabzawari (d. 1873). He was the foremost exponent of theosophical traditions who studied and elaborated the metaphysical discourse in great detail. He was also renowned for his commentary on Mulla Sadra’s (d. 1640) al-Asfar and al-Shawahid al-Rububiyyah, as well as for reviving Sadra’s teachings. The best example of Sabzawari’s philosophical theory, which he developed and expounded, is recorded in his magnum opus, the commentary of Ghurar al-Fara’id. His ideas and writings influenced many Persian intellectuals who came after him. This article also re-examines some conclusions by previous reseachers regarding the study on Sabzawari. This will be followed by a brief explanation on the characteristics of Sabzawari’s works, including its style and structure of writing, the content of the discussion, and its significance. This study is based on a qualitative method to arrive at conclusions in which content analysis is utilized in describing the life and works of Sabzawari.

Published: October 2022

Although learning Chinese as a second language (CSL) is becoming increasingly important due to the rapid development of China's comprehensive national power, CSL learning abroad faces great challenges. This study proposes to use mobile learning (m-learning), especially mobile assisted language learning (MALL), to facilitate CSL learning. This research aimed to investigate learners' readiness to engage in m-learning, their levels of mobile perception, mobile motivation, and mobile self-efficacy, as well as the correlations between these constructs. Respondents were selected using the purposive sampling method from a private university college in Melaka, Malaysia. The total number of valid cases was 95. The three instruments which were adopted to collect data in this study were examined the reliability and validity with pilot study. Descriptive analysis revealed that respondents had moderate levels of mobile perception, mobile motivation, and mobile self-efficacy. Bivariate correlation analysis revealed that all three constructs were highly correlated. Perceived usefulness (PU) ranked comparatively first, followed by perceived ease to use (PEOU) and perceived difficulty (PD). Respondents who perceived difficulty found mobile apps less useful. Respondents who perceived ease to use and usefulness were more motivated than respondents who perceived difficulty. Respondents who perceived difficulty preferred more outside help rather than relying on themselves. Respondents with moderate self-efficacy (MSE) were more motivated than respondents with high self-efficacy (HSE). In general, respondents in the higher education system have their own mobile device and are ready for m-learning. Therefore, policy makers and teachers should consider integrating m-learning and MALL into the classroom to improve formal teaching.
