The relationship between mind wandering and reading comprehension: A meta-analysis
Authors: Bonifacci Paola , Viroli Cinzia , Vassura Chiara , Colombini Elisa , Desideri Lorenzo
Published: July 2022

Mind wandering (MW), a shift of attention away from external tasks toward internally generated thoughts, has been frequently associated with costs in reading comprehension (RC), although with some contrasting results and many reported potential intervening factors. The aim of the meta-analysis was to evaluate the relationship between MW and RC, considering the role of participants’ and text’s characteristics, as well as methodological issues in the measurement of the two constructs. From a set of 25 selected full texts (73 correlation coefficients), pooled correlation (r = −0.21) revealed a negative significant relationship. Using trait-based questionnaires to assess MW compared with online probes resulted in an average significant change of 0.30 in the correlation between MW and RC, leading to a null correlation. A significant effect of age was also found, with more negative correlations with increasing age. None of the other moderating variables considered (i.e., language, text type, text length, RC assessment, text difficulty, text interest, and working memory) resulted in a significant effect. From the present meta-analysis, we might suggest that MW and RC are partially overlapping and vary, within a swing effect, in relation to a set of shared factors, such as working memory, interest, and text length. There might also be side-specific factors that drive the movement of primarily one side of the swing, and future research should further consider the role of individual differences in RC. Implications for research and educational settings are discussed.

The development of automotive technology is very fast, we can find this in today's vehicles that use a lot of very sophisticated technology, namely in terms of engines, electricity, and its newest features, especially on two-wheeled vehicles. Therefore, the user community is required to be more selective in choosing a vehicle both in terms of quality and quantity. Including in the selection of spare parts on vehicle engines must use good quality, this is useful as a motorbike power booster, especially in the ignition system, namely spark plugs as a vital tool that sprinkles sparks in the combustion chamber. Recently, many spark plugs have been found that are not good enough so that the power generated by the vehicle is reduced. The purpose of this test is as a Comparative Test of the Endurance of Various Motorcycle Spark Plugs by using a spark plug tester so that it can be seen that the spark plug is suitable or not used in the vehicle which aims to get maximum performance.

We report the results of analyses of galactic outflows in a sample of 45 low-redshift starburst galaxies in the COS Legacy Archive Spectroscopic SurveY (CLASSY), augmented by five additional similar starbursts with Cosmic Origins Spectrograph (COS) data. The outflows are traced by blueshifted absorption lines of metals spanning a wide range of ionization potential. The high quality and broad spectral coverage of CLASSY data enable us to disentangle the absorption due to the static interstellar medium (ISM) from that due to outflows. We further use different line multiplets and doublets to determine the covering fraction, column density, and ionization state as a function of velocity for each outflow. We measure the outflow’s mean velocity and velocity width, and find that both correlate in a highly significant way with the star formation rate, galaxy mass, and circular velocity over ranges of four orders of magnitude for the first two properties. We also estimate outflow rates of metals, mass, momentum, and kinetic energy. We find that, at most, only about 20% of silicon created and ejected by supernovae in the starburst is carried out in the warm phase we observe. The outflows’ mass-loading factor increases steeply and inversely with both circular and outflow velocity (log–log slope ∼−1.6), and reaches ∼10 for dwarf galaxies. We find that the outflows typically carry about 10%–100% of the momentum injected by massive stars and about 1%–20% of the kinetic energy. We show that these results place interesting constraints on, and new insights into, models and simulations of galactic winds.

We present LOw Frequency ARray observations of the Coma Cluster field at 144 MHz. The cluster hosts one of the most famous radio halos, a relic, and a low surface brightness bridge. We detect new features that allow us to make a step forward in the understanding of particle acceleration in clusters. The radio halo extends for more than 2 Mpc, which is the largest extent ever reported. To the northeast of the cluster, beyond the Coma virial radius, we discover an arc-like radio source that could trace particles accelerated by an accretion shock. To the west of the halo, coincident with a shock detected in the X-rays, we confirm the presence of a radio front, with different spectral properties with respect to the rest of the halo. We detect a radial steepening of the radio halo spectral index between 144 and 342 MHz, at ∼30′ from the cluster center, that may indicate a non-constant re-acceleration time throughout the volume. We also detect a mild steepening of the spectral index toward the cluster center. For the first time, a radial change in the slope of the radio–X-ray correlation is found, and we show that such a change could indicate an increasing fraction of cosmic-ray versus thermal energy density in the cluster outskirts. Finally, we investigate the origin of the emission between the relic and the source NGC 4789, and we argue that NGC 4789 could have crossed the shock originating the radio emission visible between its tail and the relic.

Published: July 2022

We discuss the statistical distribution of galaxy shapes and viewing angles under the assumption of triaxiality by deprojecting observed surface brightness profiles of 56 brightest cluster galaxies (BCGs) coming from a recently published large deep-photometry sample. For the first time, we address this issue by directly measuring axis ratio profiles without limiting ourselves to a statistical analysis of average ellipticities. We show that these objects are strongly triaxial, with triaxiality parameters 0.39 ≤ T ≤ 0.72, they have average axis ratios 〈p(r)〉 = 0.84 and 〈q(r)〉 = 0.68, and they are more spherical in the central regions but flatten out at large radii. Measured shapes in the outskirts agree well with the shapes found for simulated massive galaxies and their dark matter halos from both the IllustrisTNG and the Magneticum simulations, possibly probing the nature of dark matter. In contrast, both simulations fail to reproduce the observed inner regions of BCGs, producing objects that are too flattened.

, z < 0.6) active galactic nuclei (AGN) from the all-sky Swift Burst Array Telescope X-ray survey observed with the Very Large Telescope (VLT)/X-shooter in the near-infrared (NIR; 0.8–2.4 μm). We find that 49/109 (45%) Seyfert 2 and 35/58 (60%) Seyfert 1 galaxies observed with VLT/X-shooter show at least one NIR high-ionization coronal line (CL; ionization potential χ > 100 eV). Comparing the emission of the [Si vi] λ1.9640 CL with the X-ray emission for the DR2 AGN, we find a significantly tighter correlation, with a lower scatter (0.37 dex) than that for the optical [O iii] λ5007 line (0.71 dex). We do not find any correlation between CL emission and the X-ray photon index Γ. We find a clear trend of line blueshifts with increasing ionization potential in several CLs, such as [Si vi] λ1.9640, [Si x] λ1.4300, [S viii] λ0.9915, and [S ix] λ1.2520, indicating the radial structure of the CL region. Finally, we find a strong underestimation bias in black hole mass measurements of Sy 1.9 using broad Hα due to the presence of significant dust obscuration. In contrast, the broad Paα and Paβ emission lines are in agreement with the M–σ relation. Based on the combined DR1 and DR2 X-shooter sample, the NIR BASS sample now comprises 266 AGN with rest-frame NIR spectroscopic observations, the largest set assembled to date.

Virial black hole (BH) mass (M
BH) determination directly involves knowing the broad-line region (BLR) clouds’ velocity distribution, their distance from the central supermassive BH (R
BLR), and the virial factor (f). Understanding whether biases arise in M
BH estimation with increasing obscuration is possible only by studying a large (N > 100) statistical sample of obscuration-unbiased (hard) X-ray-selected active galactic nuclei (AGNs) in the rest-frame near-infrared (0.8–2.5 μm) since it penetrates deeper into the BLR than the optical. We present a detailed analysis of 65 local Burst Alert Telescope (BAT) selected Seyfert galaxies observed with Magellan/FIRE. Adding these to the near-infrared BAT AGN spectroscopic survey database, we study a total of 314 unique near-infrared spectra. While the FWHMs of Hα and near-infrared broad lines (He i, Paβ, Paα) remain unbiased to either BLR extinction or X-ray obscuration, the Hα broad-line luminosity is suppressed when N
H ≳ 1021 cm−2, systematically underestimating M
BH by 0.23–0.46 dex. Near-infrared line luminosities should be preferred to Hα until N
H < 1022 cm−2, while at higher obscuration a less-biased R
BLR proxy should be adopted. We estimate f for Seyfert 1 and 2 using two obscuration-unbiased M
BH measurements, i.e., the stellar velocity dispersion and a BH mass prescription based on near-infrared and X-ray, and find that the virial factors do not depend on the redshift or obscuration, but some broad lines show a mild anticorrelation with M
BH. Our results show the critical impact obscuration can have on BLR characterization and the importance of the near-infrared and X-rays for a less-biased view of the BLR.

We present the second catalog and data release of optical spectral line measurements and active galactic nucleus (AGN) demographics of the BAT AGN Spectroscopic Survey, which focuses on the Swift-BAT hard X-ray detected AGNs. We use spectra from dedicated campaigns and publicly available archives to investigate spectral properties of most of the AGNs listed in the 70 month Swift-BAT all-sky catalog; specifically, 743 of the 746 unbeamed and unlensed AGNs (99.6%). We find a good correspondence between the optical emission line widths and the hydrogen column density distributions using the X-ray spectra, with a clear dichotomy of AGN types for N
H = 1022 cm−2. Based on optical emission-line diagnostics, we show that 48%–75% of BAT AGNs are classified as Seyfert, depending on the choice of emission lines used in the diagnostics. The fraction of objects with upper limits on line emission varies from 6% to 20%. Roughly 4% of the BAT AGNs have lines too weak to be placed on the most commonly used diagnostic diagram, [O iii]λ5007/Hβ versus [N ii]λ6584/Hα, despite the high signal-to-noise ratio of their spectra. This value increases to 35% in the [O iii]λ5007/[O ii]λ3727 diagram, owing to difficulties in line detection. Compared to optically selected narrow-line AGNs in the Sloan Digital Sky Survey, the BAT narrow-line AGNs have a higher rate of reddening/extinction, with Hα/Hβ > 5 (∼36%), indicating that hard X-ray selection more effectively detects obscured AGNs from the underlying AGN population. Finally, we present a subpopulation of AGNs that feature complex broad lines (34%, 250/743) or double-peaked narrow emission lines (2%, 17/743).

We present new central stellar velocity dispersions for 484 Sy 1.9 and Sy 2 from the second data release of the Swift/BAT AGN Spectroscopic Survey (BASS DR2). This constitutes the largest study of velocity dispersion measurements in X-ray-selected obscured active galactic nuclei (AGN) with 956 independent measurements of the Ca ii H and K λ3969, 3934 and Mg I λ5175 region (3880–5550 Å) and the calcium triplet region (8350–8730 Å) from 642 spectra mainly from VLT/X-Shooter or Palomar/DoubleSpec. Our sample spans velocity dispersions of 40–360 km s1, corresponding to 4–5 orders of magnitude in black hole mass (M
BH = 105.5−9.6
M
⊙), bolometric luminosity (L
bol ∼ 1042–46 erg s−1), and Eddington ratio (L/L
Edd ∼ 10−5 to 2). For 281 AGN, our data and analysis provide the first published central velocity dispersions, including six AGN with low-mass black holes (M
BH = 105.5−6.5
M
⊙), discovered thanks to high spectral resolution observations (σ
inst ∼ 25 km s−1). The survey represents a significant advance with a nearly complete census of velocity dispersions of hard X-ray–selected obscured AGN with measurements for 99% of nearby AGN (z < 0.1) outside the Galactic plane (∣b∣ > 10°). The BASS AGN have much higher velocity dispersions than the more numerous optically selected narrow-line AGN (i.e., ∼150 versus ∼100 km s−1) but are not biased toward the highest velocity dispersions of massive ellipticals (i.e., >250 km s−1). Despite sufficient spectral resolution to resolve the velocity dispersions associated with the bulges of small black holes (∼104–5
M
⊙), we do not find a significant population of super-Eddington AGN. Using estimates of the black hole sphere of influence from velocity dispersion, direct stellar and gas black hole mass measurements could be obtained with existing facilities for more than ∼100 BASS AGN.

Hera is a planetary defense mission under development in the Space Safety and Security Program of the European Space Agency for launch in 2024 October. It will rendezvous in late 2026 December with the binary asteroid (65803) Didymos and in particular its moon, Dimorphos, which will be impacted by NASA’s DART spacecraft on 2022 September 26 as the first asteroid deflection test. The main goals of Hera are the detailed characterization of the physical properties of Didymos and Dimorphos and of the crater made by the DART mission, as well as measurement of the momentum transfer efficiency resulting from DART’s impact. The data from the Hera spacecraft and its two CubeSats will also provide significant insights into asteroid science and the evolutionary history of our solar system. Hera will perform the first rendezvous with a binary asteroid and provide new measurements, such as radar sounding of an asteroid interior, which will allow models in planetary science to be tested. Hera will thus provide a crucial element in the global effort to avert future asteroid impacts at the same time as providing world-leading science.

The Light Italian Cubesat for Imaging of Asteroids (LICIACube) is part of the NASA Double Asteroid Redirection Test (DART), the first mission aiming to demonstrate the applicability of the kinetic impactor method for planetary defense. The mission was launched on 2021 November 24 to perform the impact experiment on Dimorphos, the small secondary of the binary asteroid (65803) Didymos. The 6U LICIACube, stored as a piggyback of the DART spacecraft, is the first Italian mission operating in deep space managed by the Italian Space Agency that will witness the effects of the DART impact on Dimorphos. On board LICIACube, there is a suite of cameras that will perform imaging of Didymos and Dimorphos to investigate the DART impact effects and study the binary system. Among them, the LICIACube Unit Key Explorer (LUKE), a wide-angle camera coupled to an RGB Bayer pattern filter, will be pivotal to constrain the surface composition and heterogeneity of the binary system due to differences in surface properties linked with possible space weathering effects and/or the presence of exogenous material. Multiband photometric analysis of LUKE data and laboratory experiments in support of data interpretation will provide new insights on the binary asteroid nature and evolution. Moreover, photometric phase curve analysis will reveal the scattering properties of the granular surface medium providing important constraints for the microphysical properties of the Didymos–Dimorphos system. In this work, we will present the state of the art of the LUKE scientific activities with an overview of the instrument setup, science operations, and expected results.

Authors: Fakhriani Rizka , Widuri Asti
Published: July 2022

BACKGROUND: SARS-CoV-2, which causes COVID-19, is one of the viruses that has been spreading globally since 2019.

AIM: This research aims to see how common anosmia is among COVID-19 patients.

MATERIALS AND METHODS: A retrospective study with a consecutive sample and quantitative descriptive design was utilized to collect data by spreading questionnaires on patient experiences COVID-19 infection. COVID-19 was detected by RT-PCR at a Health Center in Yogyakarta, Indonesia.

RESULT: A total of 124 persons tested positive for COVID-19. The remaining 59% experienced no anosmia or smell issues. Anosmia was present in 40.3% of those examined, 57.3% of those tested had no anosmia before or after the RT-PCR test and 31.5 had it before being diagnosed with COVID-19. Less than 5 days, 13.7% of those who had recovered, whereas 22.6% had more than 5 days to recover.

CONCLUSION: People who were diagnosed as COVID-19 positive using the RT-PCR test had the symptom earlier than those who reported anosmia after diagnosis, according to when they first reported it.
Dual-Energy Computed Tomography Has Additional Prognostic Value Over Clinical Measures in Gout Including Tophi: A Systematic Literature Review
Authors: Stauder Sally K. , Peloso Paul M.
Published: July 2022

Objective

This systematic literature review determined whether there is clinical utility for dual-energy computed tomography (DECT) to inform on prognosis for patients with gout. With DECT, individualized treatment plans could be developed based on the patient's unique urate burden, with DECT being used as a clinical outcome measure in gout management.

Methods

To evaluate DECT as a reliable, valid, and sensitive prognostic instrument, a librarian-assisted search was undertaken in PubMed and Embase for articles on gout and DECT informing on reliability; content, construct, and criterion validity; sensitivity to change; and minimum clinically important changes.

Results

This systematic literature review showed that DECT has high intra- and interrater reliability. Tophus burden correlates with functional loss to show content validity. DECT volume is positively correlated with death, cardiovascular risk factors, and the risk for future gout flares. DECT has excellent sensitivity to change with effective urate-lowering therapies.

Conclusion

DECT is a promising prognostic tool based on its high reliability, sensitivity to change, and emerging validity. Additional large, well-designed, prospective cohort studies are needed to fully evaluate its prognostic utility. This systematic review suggests that DECT very likely has additional prognostic information beyond clinical tophi assessment alone.

Published: July 2022

Objective

To evaluate fatigue frequency and severity among patients with psoriatic arthritis (PsA) and assess the effect of fatigue severity on patient-reported outcome measures (PROMs) assessing quality of life, function, and work productivity.

Methods

Data were derived from the Adelphi Disease Specific Programme, a cross-sectional survey conducted in 2018 in the United States and Europe. Patients had physician-confirmed PsA. Fatigue was collected as a binary variable and through its severity (0-10 scale, using the 12-item Psoriatic Arthritis Impact of Disease fatigue question) from patients; physicians also reported patient fatigue (yes/no). Other PROMs included the 5-level EuroQol 5-dimension questionnaire (EQ-5D-5L) for health-related quality of life (HRQOL), Health Assessment Questionnaire–Disability Index, and Work Productivity and Activity Impairment Questionnaire. Multivariate linear regression was used to evaluate the association between fatigue severity and other PROMs.

Results

Among the 831 included patients (mean age 47.5 yrs, mean disease duration 5.3 yrs, 46.9% female, 48.1% receiving a biologic), fatigue was reported by 78.3% of patients. Patients with greater fatigue severity had greater disease duration, PsA severity, pain levels, body surface area affected by psoriasis, and swollen and tender joint counts (all P < 0.05). In multivariate analyses, patients with greater fatigue severity experienced worse physical functioning, HRQOL, and work productivity (all P < 0.001). Presence of fatigue was underreported by physicians (reported in only 32% of patients who self-reported fatigue).

Conclusion

Prevalence of patient-reported fatigue was high among patients with PsA and underrecognized by physicians. Fatigue severity was associated with altered physical functioning, work productivity, and HRQOL.

Published: July 2022

Objective

To develop and validate a patient knowledge questionnaire regarding axial spondyloarthritis (axSpA).

Methods

Knowledge considered essential for patients with axSpA was identified through Delphi rounds among rheumatologists, healthcare professionals (HCPs), and patients, then reformulated to develop the knowledge questionnaire. Cross-sectional validation was performed in 14 rheumatology departments to assess internal validity (Kuder-Richardson coefficient), external validity, acceptability, reproducibility (Lin concordance correlation coefficient), and sensitivity to change (knowledge score before vs after patient education sessions and effect size).

Results

The Spondyloarthritis Knowledge Questionnaire (SPAKE) is a self-administered 42-item questionnaire with a 32-item short form, both scored 0 to 100, assessing knowledge of disease, comorbidities, pharmacological treatments, nonpharmacological treatments, self-care, and adaptive skills. In the validation study (130 patients; 67 [51.5%] male, mean age 43.5 [SD 12.9] yrs), the mean (SD) score of the long-form questionnaire was 71.6 (15.4), with higher scores (better knowledge) in nonpharmacological treatments and adaptive skills and lower scores in cardiovascular comorbidity and pharmacological treatments. Acceptability was good, with no missing data; the internal validity coefficient was 0.85. Reproducibility was good (0.81, 95% CI 0.72-0.89). SPAKE showed good sensitivity to change; scores were 69.2 (15.3) then 82.7 (14.0) after patient education sessions (Hedges effect size = 0.92, 95% CI 0.52-1.31).

Conclusion

SPAKE is a knowledge questionnaire for patients with axSpA, developed with the involvement of HCPs and patients and reflecting current recommendations for the management of axSpA. SPAKE will be useful in assessing knowledge acquisition and self-management strategies in routine care and research.
Vulnerability to COVID-19 Infection in Milwaukee
Authors: Xu Zengwang , Logan John
Published: July 2022

This study focuses on variation of the prevalence rate of COVID-19 over time by age and race/ethnicity, and how neighborhood social vulnerability affects the COVID-19 prevalence in the whole epidemic as well as its three consecutive sub-waves in Milwaukee County, Wisconsin. It found that the highest prevalence rate was for young adults (18-44). Hispanics and Asians were more likely to be infected than were non-Hispanic whites and African Americans. The high neighborhood social vulnerability was associated with greater risk of infection especially for persons over age 25, for Hispanics and Asians. High prevalence rates were significantly and strongly associated with all major factors of the social vulnerability in early stage of the pandemic, especially with the factor associated with Hispanic and immigrant population. Throughout the epidemic, the Hispanic/immigrant and African American factors had a reduced but still significant effect, but the socioeconomic factor was not significant and the explained variance across neighborhoods was smaller.

Agile development methodology has become popular among software developers. Some non-agile developers integrate certain agile and design thinking practices in their development. Among these practices include identifying personas, creating empathy and journey maps and writing user stories. This research adopts the Design Science Research Methodology, focusing on integrating agile and design thinking practices in generating quality user stories in the design of augmented reality (AR) applications. An integrated development process is modelled and applied in an example application, an AR application for student welfare services events. The study goes through the process of eliciting user requirements by identifying user personas, creating empathy maps and customer journeys and writing user stories as part of the discovery stage of the AR application development. The user stories are evaluated by fifteen agile practitioners based on fourteen criteria adapted from Quality User Story Framework. The user stories are scored and assessed to determine the level of quality.

Portable interfaced robot arms equipped with mobile user interactions are significantly being utilized in modern world. The application of teaching robotics is being used in challenging pandemic situation but it is still challenging due to mathematical formulation. This article utilizes the augmented reality (AR) concept for remote control-based human-robot interaction using the Bluetooth correspondence. The proposed framework incorporates different modules like a robot arm control, a regulator module and a distant portable smartphone application for envisioning the robot arm points for its real-time relevance. This novel approach fuses AR innovation into portable application which permit the continuous virtual coordination with actual physical platform. The simulation yields effective outcomes with 96.94% accuracy for testing stage while maintaining error and loss values of 0.194 and 0.183 respectively. The proposed interface gives consistent results for teaching application in real time changing environment by outperforming existing methods with an accuracy improvement of 13.4

Authors: Altin Hakan
Published: July 2022

The primary objective of this study is to create the first examination of the global stock markets using the ARDL method. The ARDL model provides a solution that shows the short-run and long-run relationships together by removing the constraint of the series that are stationary in the traditional cointegration models. The period examined in the study, in which daily data is used, is between 01/03/2000 – 12/31/2022. Two significant results were obtained as a consequence of the implementation phase. First, there is a causal cointegration relationship between European stock markets, BRIC stocks, and American stock markets in the short run and long run. The cointegration relationship between global stock markets transforms national economies into international economies. The interdependence between global stock markets is considerably strong. This situation diminishes the utility of international diversification explained in portfolio management. Second, the relatively new ARDL technique gives similar results to conventional cointegration tests.

Intrusion Detection Using Normalized Mutual Information Feature Selection and Parallel Quantum Genetic Algorithm
Authors: Ling Zhang , Hao Zhang Jia
Published: July 2022

This paper presents a detection algorithm using normalized mutual information feature selection and cooperative evolution of multiple operators based on adaptive parallel quantum genetic algorithm (NMIFS MOP- AQGA). The proposed algorithm is to address the problems that the intrusion detection system (IDS) has lower the detection speed, less adaptability and lower detection accuracy. In order to achieve an effective reduction for high-dimensional feature data, the NMIFS method is used to select the best feature combination. The best features are sent to the MOP- AQGA classifier for learning and training, and the intrusion detectors are obtained. The data are fed into the detection algorithm to ultimately generate accurate detection results. The experimental results on real abnormal data demonstrate that the NMIFS MOP- AQGA method has higher detection accuracy, lower false negative rate and higher adaptive performance than the existing detection methods, especially for small samples sets.

Published: July 2022

Teachers' responsibility for the integration of computers constitutes a significant place in the foreign language teaching and learning processes; however, limited research found in the literature shows the need for more comprehensive studies. Therefore, this study investigates the instructors' perceptions of using computers, namely, teachers' computer knowledge, computer habits, computer attitudes, perceived self-confidence, school climate, and support in English teaching and learning at higher education institutions in Turkey. the quantitative data were collected from 210 instructors with a questionnaire consisting of a background section and a scale that has five subsections. It was concluded that while instructors had limited knowledge of specific software, their personal interests were also limited to communication and work-related tools. They mostly held positive attitudes towards computers and had self-confidence in integrating computers into the teaching process. Last, they believed their institutions had the necessary instructional and technical support and infrastructure.

Authors: Musundire Austin
Published: July 2022

This article examines effectiveness of the self-directed supervision strategy as a tool for improving teaching quality. Special reference was made to the implementation of the South African Integrated Quality Management system (IQMS). A mixed method approach characterised by the explanatory sequential design addressed the research questions. 301 out of 350 randomly selected participants in 15 districts of the Gauteng Province responded to the quantitative phase in the form of questionnaires. Three conveniently selected focus group interviews each comprising often (10) purposefully selected school-based managers and educators gave in-depth exploration of the quantitative results. Self-directed supervision was found to comply with the Total Quality Management principle of continuous improvement which was perceived to have a positive influence on improving teaching quality. In contrast, the IQMS self-evaluation was perceived to lack compliance to continuous improvement for professional development due to characteristics related to traditional inspection approaches.

The greatest difficulties in creating a new structure or upgrading an old one are associated with designing joints and connecting parts of the structure, especially composite and metal ones. Nowadays, the problem of designing and improving such joints is timely and is being actively studied so that the best solutions are found. The article presents the research carried out to determine the main parameters of elements of mechanical joints made of polymer composite materials, as factors affecting the requirements for precision of connection compliance estimation. There has been found the influence of the number of fastener rows on estimating the maximum forces which act in the joint, as well as the influence of the ratio of the connection compliance to the compliance of the part. A field of possible states of the joint has been built. Within the field, the following areas have been identified: the area of high sensitivity to precision of estimating the parameters of the joint elements, requiring experimental confirmation and more accurate models; the area of average sensitivity of the joint to precision of estimating the parameters of its elements, permitting the use of known dependences; and the area of low sensitivity, where simplified models can be used. In the course of the developed model testing, joint samples were tested to evaluate the force connection compliance, and a reference variant was calculated using the Douglas formula. The reference variant of the joint sample was chosen based on the principle of equal compliances of the parts to be joined, presented by a series of samples assembled from a composite package of 80 layers and two surface layers made of 3.98 mm-thick steel. The parts were connected with steel bolts with a diameter of 6 and 8 mm. Numerically, the ratio of the connection compliance to the part compliance is 85...96 for the experimental data, and 9...10 for the calculated data. This indicated that the joint was in the transition area between high and medium sensitivity of the joint to the accuracy of compliance estimation, which requires continuous refinement of the connection parameters.
Expanding Hydrogel Aggregate for Self-Compacting Products
Authors: Sokov Victor , Dmitriev Nikita
Published: July 2022

Hydrogel spheres made of sodium polyacrylate with free absorption of water can increase in volume by 100-1000 times due to the violation of the balance of forces of attraction and repulsion between the links of the gel. The addition of water will shift the balance in favor of the repulsive forces. This property will allow them to be used in cement systems as an active expanding aggregate, which will compact the structure, reduce the water-cement ratio during the formation of the cement paste structure, and then give water to the hardening cement stone. The hydrogel sphere itself will decrease in volume to its initial state and will leave the pore in its place. The resulting material can be considered aerated concrete with compacted inter-pore partitions. The advantage of this method over the traditional method of self-compacting masses is that there is no need to supply thermal energy to activate the expansion of the active aggregate, for example, by passing an electric current through the hardening mass. In this article, the properties of the hydrogel are investigated, the dynamics of the expansion of hydrogel spheres in water at different temperatures is determined.

Published: July 2022

Co-28Cr-6Mo alloy is widely used in aerospace industry and biomaterial engineering where high demands are placed on material strength, fatigue endurance as well as corrosion resistance. As complex shapes and weight savings are required for such components, additive manufacturing is the ideal production way. For example, Selective Laser Melting (SLM) of metallic powders is capable of achieving complex components with fine details. However, Co-28Cr-6Mo alloy prepared by SLM shows a characteristic microstructure which causes its instability at elevated temperatures that can occur during operation. To eliminate such operational problem, the component must be appropriately heat-treated. This paper demonstrates the instability of Co-28Cr-6Mo alloy prepared by SLM and proposes the heat treatment yielding its stabilization.

Published: July 2022

Electrochemical research is focused on the tungsten extraction during acid electrochemical treatment of WC-Co pseudoalloy in chloride solutions. The target resulted products of the treatment are: tungsten oxide (VI), tungsten powder with a given particle size distribution (2…3 μm). Based on the analysis of kinetics, the mechanism of dissolution of the WC-Co pseudoalloy in a solution of 2.5 mol∙dm-3 HCl and with the addition of HF was proposed. It was found that a well-soluble higher tungsten chloride is formed on the surface of the pseudoalloy, which is eventually hydrolyzed in aqueous solution to form tungsten oxides. The dispersion control levers were investigated and the technological parameters of obtaining tungsten metal powder from low-temperature ionic alloys (NaCl-KCl-CsBr-NaF) were determined, which make it possible to obtain tungsten metal powder of a given particle size distribution. It is stated that the use of tungsten powder (W or WO3) for the modification of aramid fiber can significantly increase the heat resistance of aramid fabric and reduce its wear
