Effect of cyclic loading on mechanical properties and microstructure of die cast magnesium alloy AZ91D
Authors: Li Jiquan , Hao Weina , Wang Fenghua , Jiang Shaofei , Gan Huiqi , Zhou Jun
Published: June 2022

Magnesium alloy materials are often affected by cyclic stress, resulting
in fatigue fracture due to changes in mechanical properties. In this
study, external cyclic loads were introduced to simulate the loading of
AZ91D(Mg-9Al-0.5Zn) parts. Tensile tests under static and external
circulation loads were performed on the same specimens, and the effect
of loading conditions on the mechanical properties of the specimens
(tensile strength, yield strength and elongation) were studied. The
internal microstructure of the test specimens was analyzed, and the
influence of cyclic loading on the microstructure change of the
specimens was discussed. Compared with static load, under the condition
of cyclic loading, the tensile strength and yield strength of the
specimens are increased by more than 15%, and the elongation rate is
increased by 3 times. In addition, the microstructure images showed that
many twins and the second phase β-Mg Al
were generated inside the AZ91D microstructure under
cyclic loading. The former results in specimens crack initiation and it
is the root cause of fatigue fracture. And the latter accounts for the
strengthening of the mechanical properties of specimens.
Formation control of large-scale mobile sensor networks based on semilinear parabolic system
Authors: Qian Xueming , Cui Baotong
Published: June 2022

This paper is concerned with the formation control problem for a class
of large-scale mobile sensor networks. The dynamic of mobile sensors are
modeled by class of semilinear parabolic system, which is a class of
partial differential equation(PDE) and has rich geometric family. In
this model, the communication topology of agents is a chain graph and
fixed. Leader feedback laws which designed in a manner to the boundary
control of semilinear parabolic system allow the mobile sensors stable
deployment onto planar curves. By constructing appropriate Lyapunov
functional and using linear matrix inequality, several sufficient
criteria are derived ensuring the mobile sensor networks to be globally
asymptotically stable at the equilibrium. A simulation example is
provided to demonstrate the usefulness of the proposed formation control
scheme.

Published: June 2022

We herein report a 76-year-old man with acquired hemophilia A (AHA) who
developed gallbladder rupture due to Ceftriaxone (CTRX)-associated
pseudolithiasis. The patient was admitted for an examination of systemic
subcutaneous bleeding. A blood test showed a prolonged activated partial
thromboplastin time and sequentially revealed low factor VIII activity
(<1%) and a high factor VIII inhibitor level of 143 BU/mL.
The patient was thus diagnosed with AHA. After admission, he developed a
high-grade fever and was administered intravenous CTRX, considering the
possibility of psoas abscess or cellulitis. Although his high-grade
fever was improved, computed tomography incidentally showed a
high-density lesion in the gallbladder, suggestive of CTRX-associated
pseudolithiasis without clinical symptoms. Despite cessation of CTRX,
the pseudolithiasis never disappeared, and the patient suddenly died
after rapid progression of abdominal bloating. An autopsy revealed that
the gallbladder was severely swollen and had ruptured with hemorrhaging
because of hemorrhagic cholecystitis, caused by CTRX-associated
pseudolithiasis with AHA. Our case demonstrated that CTRX-associated
pseudocholelithiasis can unexpectedly induce gallbladder hemorrhaging
and rupture in a patient with a bleeding diathesis, including AHA.
CTRX-associated pseudocholelithiasis can cause a fatal outcome in
patients with a bleeding disorder, even if CTRX is ceased as soon as
pseudocholelithiasis is detected.

Published: June 2022

  

Objective: Individuals with type 1 diabetes (T1DM) are living to ages when neuropathological changes are increasingly evident. We hypothesized that middle-aged and older adults with long-standing T1DM will show abnormal brain structure in comparison to non-diabetic controls.

Research Design and Methods: Magnetic resonance imaging (MRI) was used to compare brain structure among 416 T1DM participants in the Epidemiology of Diabetes Interventions and Complications (EDIC) study with 99 demographically similar non-diabetic controls at 26 U.S. and Canadian sites. Assessments included total brain (TBV, primary outcome), gray matter (GMV), white matter (WMV), ventricle and white matter hyperintensity (WMH) volumes and white matter fractional anisotropy (FA). Biomedical assessments included HbA1c and lipid levels, blood pressure, and cognitive assessments of memory and psychomotor and mental efficiency (PME). Among EDIC participants, HbA1c, severe hypoglycemia history, and vascular complications were measured longitudinally. 

Results: Mean age of EDIC participants and controls was 60 years. T1DM participants showed significantly smaller TBV (1206 ± 1.7 vs. 1229 ± 3.5 cm3, p<0.0001), GMV and WMV, larger ventricle and WMH volumes, but no differences in mean white matter FA versus controls. Structural MRI measures in T1DM were equivalent to controls who are 4 to 9 years older. Lower PME scores were associated with altered brain structure on all MRI measures in T1DM participants. 

Conclusions: Middle-aged and older adults with T1DM showed brain volume loss and increased vascular injury in comparison to non-diabetic controls, equivalent to 4 to 9 years of brain aging.

Objective: To explore risks and associated mediation effects of developing chronic kidney disease (CKD) and heart failure (HF) in young- and usual-onset T2DM among White Caucasian (WC) and African American (AA).

Research Design and Methods: From US medical records, 1,491,672 WC and 31,133 AA were identified and stratified by T2DM-onset age (18-39 /40-49 /50-59 /60-70 years). Risks, mediation effects and time to CKD and HF were evaluated adjusting for time-varying confounders.

Results: In 18-39, 40-49, 50-59, 60-70 year-groups, HR (95% CI) of developing CKD /HF in AA compared to WC were 1.21 (1.17-1.26) /2.21 (1.98-2.45), 1.25 (1.22-1.28) /1.86 (1.75-1.97), 1.21 (1.19-1.24) /1.54 (1.48-1.60), 1.10 (1.08-1.12) /1.11 (1.07-1.15) respectively. In AA /WC aged 18-39 years, time (CI) in years to CKD [8.7 (8.2-9.1) /9.7 (9.2-10.2)] and HF [10.3 (9.3-11.2) /12.1 (10.6-13.5)] were on average 3.6 /4.0 and 3.1 /4.1 years longer compared to those diagnosed at 60-70 years.

Compared to females, AA males aged <60 years had 11-49% higher CKD risk, while WC males aged <40 years had 23% higher and those aged 50+ had 7-14% lower CKD risk respectively. 

The mediation effects (%) of CKD on the HF risk difference between ethnicities across age-groups (range: 54-91%) were higher compared to those of HF on CKD risk difference between ethnicities across age-groups (range: 13-39%). 

Conclusions: Developing cardio-renal complications on average within 10 years of young-onset T2DM, and high mediation effect of CKD on HF call for revisiting guidelines on early diagnosis and pro-active treatment strategies for effective management of cardio-metabolic risk.

Assessment of Health Sciences Students’ Knowledge and Awareness of the Covid-19 Pandemic: Sample of One University from Turkey
Authors: Aygün Mahmure , Murat Merve
Published: June 2022

Individuals getting information and understanding of the Covid-19 pandemic that shook the world are intimately tied to the disease's prevention and decreasing its severity. The purpose of the study is to determine the fundamental level of Covid-19 disease knowledge-awareness among university students studying health sciences. The study is descriptive and cross-sectional. The data were gathered using an online test administered by a private university between June and July 2020. It consists of 25 multiple-choice questions covering seven knowledge-awareness subject areas, including virus knowledge, diagnosis, prognosis, and treatment. 339 students from 14 different healthcare fields took part in the study. All students had a 15.4±3.0 correct answer average, a 61.7±14.5 total score average, and a moderate level of information awareness (=50–64 points). Seven of the test’s questions (1, 4, 13, 15, 18, 21, and 22) were answered correctly by ≥71% of the students. Seven questions (5, 7, 8, 16, 1, 19, and 2), on the other hand, received a £50% correct response rate. For the pandemic question, the meaning of the reproduction number (R-value) received the lowest percentage of correct answers (37.5%). When asked about their names and implications, the virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and cytokine storm had poor knowledge rates (41.3% and 46.0%, respectively). Students of the School of Medicine, Faculty of Dentistry, and Pharmacy had greater correct response rates (68.4%), than those studying at the Faculty of Health Sciences and Vocational School (60.3% and 58.3%, p=0.001, respectively). The level of knowledge-awareness regarding Covid-19 disease among students was determined to be modest. The findings imply that students struggle with independent orientation to scientific information, curiosity, and agenda-following. Some improvements, such as regular information sessions and a separate course hour dedicated to this subject in the curriculum to manage the pandemic are suggested.

Measurements of near-surface radial profiles of electrophysical characteristics of cylindrical objects by the eddy current method using a priori data
Authors: Halchenko Volodymyr , Storchak Anatolii , Tychkov Volodymyr , Trembovetska Ruslana
Published: June 2022

A new multiparameter express method for eddy-current measurement of radial near-surface profiles of electrophysical parameters of cylindrical control objects with a priori accumulation of information about them is proposed. The method combines in-situ measurements and model calculations using high-performance computing technologies of artificial intelligence based on neural networks, carried out both in advance in order to obtain specific information about objects, and directly in the process of performing measurements to quickly obtain a result. Mathematically, the method is based on the unique ability to quickly solve Maxwell's equations as a result of its approximation by deep neural networks without actually explicitly executing this solution. This allows deep learning to be used not only in the forward direction, but also in the opposite direction, i.e. apply to solve inverse measuring problems. The method is universal and can be extended to multiparameter measurement control with simultaneous additional determination of the diameter of a cylindrical object. The adequacy of the proposed method by numerical experiments is proved; examples of the implementation of all stages of its application are given. Algorithms and a complex of programs in the Python 3 environment have been created, which make it possible to practically implement the method. The profile measurement accuracy established on model calculations is characterized by maximum relative errors not exceeding 0.5%, provided that the probe signal is perfectly fixed. It is possible to generalize the use of the proposed method to similar eddy current measurements with surface probes of profiles of material parameters of flat objects.

Published: June 2022

The article presents the results of the energy efficiency study and light quality of LED illuminators (lamps) for general lighting, in particular colorimetric parameters, light flux modulation and photobiological safety. It is shown that two-base LED lamps with G13 base and luminaires for outdoor lighting have achieved energy efficiency class A++. LED lamps with E27 base and indoor lighting fixtures with light diffusers have a light output 25–35% lower and correspond to energy efficiency classes A+, A, B. Correlated color temperature (FTA) of indoor lighting fixtures is mainly in the range of 3000–4500 K, and the total color rendering index Ra – in the range of 71–86 units. The deviation of chromaticity from nominal values can reach 7+ degrees of McAdam ellipses (7+ standard deviations of SDCM comparison color). The angular non-uniformity of color in luminaires with diffuse light diffusers does not exceed 3 SDCM, and for luminaires without light diffusers and with lens optics - can exceed 7+ SDCM.

It is shown that LED luminaires for indoor lighting have a mainly safe level of flicker and visibility of the stroboscopic effect. In the frequency range up to 80 Hz, the flicker level, which is observed with a probability of 50% lower than incandescent lamps with a power of 60 watts. In the frequency range up to 3000 Hz, the modulation depth corresponds to a level that does not create adverse biological effects.

LED lamps and illuminators for general lighting entering the lighting market do not exceed the parameters of the insignificant risk danger group of blue light RG1. Lamps and illuminators using diffuse light diffusers belong to the general group RG0 (no risk).

Conclusions are made on energy efficiency and light quality of LED lamps.

Published: June 2022

The current stage of scientific and technical development is characterized by the widespread use of high-voltage technology. Metrological traceability has such important elements as calibration of measurement standards and measuring instruments and evaluation of measurement uncertainty. The range of values of specific measurands, the range of necessary measurement uncertainties and the measurement standards used are presented as metrological traceability chains. Building such chains for different types of measurements is important for national metrology institutes and calibration laboratories.

An urgent task is to build metrological traceability chains for high direct current voltage measuring instruments. The proposed metrological traceability hierarchy chains are used in the State Enterprise “Ukrmetrteststandard” for calibration of working standards and working measuring instruments for high DC voltage and voltages ratio. These chains can be used also by accredited calibration laboratories, which carry out calibration of working measuring instruments for high direct current voltage and voltages ratio according to their own scope of accreditation.

Abstract
The article describes the procedure for performing international bilateral comparisons of the national measurement standards of the units of gas volume and volume flow in Ukraine and Moldova. The comparisons were carried out within COOMET Project 684/MD/16 “Pilot comparisons of national standards in the field of gas flow”. The list of reference standards that took part in comparisons is indicated. The range of gas volume flow, in which the comparisons were carried out, is from 0.5 m3/h to 50 m3/h. For the flow range from 0.5 m3/h to 1 m3/h, a drum-type meter was used, and for the range from 2 m3/h to 50 m3/h, comparisons were performed using a rotary gas meter. It is indicated that the national state primary and secondary standards of the gas volume and volume flow units took part in the comparisons from Ukraine, while from Moldova it was the national standard of the gas volume flow unit. A brief description of the national measurement standards and the principle of reproduction of the gas volume and volume flow units is presented. In particular, it was noted that the primary and secondary standards of Ukraine are built on the basis of bell-type prover, and the standard of Moldova combines a piston and bell-type prover. The method of calculating, calculation of expanded uncertainty and determining the degree of equivalence of the national standards of Ukraine and Moldova are demonstrated. The results of bilateral comparisons in the form of Table 1 are presented and shown in Fig. 4. The degree of equivalence of the national standards does not exceed 0.41, which indicates that the primary and secondary standards reproduce the gas volume and volume flow units with declared uncertainties, and transfer standards retain their metrological characteristics throughout the cycle of comparisons. General conclusions are drawn about the success of bilateral comparisons.

This study specifically discusses the representation of Orlando shooting, the deadliest mass shooting in the modern U.S. history taking place on June 11, 2016 in Florida, including the portrayal of the Muslim offender and the similarities and differences in contents of the shooting coverage in online news articles of two media, Fox News and Al Jazeera. Online news articles about the shooting from Fox News and Al Jazeera were selected as the data in this study. Social Actor Representation of Van Leeuwen (2008), News Schemata of Van Dijk (1986), and the analysis of socio-cultural practices of Fairclough (1995) were used to analyze data. The results of analysis showed that there were eight representational categories used by both media to portray the offender. In addition, both media provided similar coverage about the details and chronology of the shooting, the previous investigations on the offender, and comments from witnesses and the owner of the club, but differed in presenting the offender’s personal details and his association to ISIS terrorist group. Lastly, there were three socio-cultural practices – institutional context, situational context, and societal context – that explained the shooting and its different coverage in both media.
