Effect of circulating current on input line current of 12-pulse rectifier with active inter-phase reactor

This study analyses quantitatively the effect of circulating current's amplitude and phase on the input line current of 12-pulse rectifier with active inter-phase reactor. The input line current and its total harmonic distortion (THD) are calculated under different amplitudes and phases of circulating current, and according to the calculation results, the effect of circulating current is analysed. Different from the previous results, it is obtained that the system has better performance when the amplitude of circulating current is slightly less than, but not equal to the half of load current. Both phase lagging and leading increase the THD of input line current. Some simulation and experiment are carried out to validate the theoretical analysis.
Characteristics of Sub-Aerially Emplaced Pyroclasts in the Surtsey Eruption Deposits: Implications for Diverse Surtseyan Eruptive Styles

The 1963–1967 shallow-to-emergent eruption in Iceland’s Vestmannaeyjar earned a place in the history of volcanology by creating the island of Surtsey while under close observation of volcanologist Sigurdur Thorarinsson (Sigurður Þórarinsson in Icelandic). This is an example of what is now called Surtseyan volcanism, and it included explosive and effusive phases from multiple vents that formed the island of Surtsey itself, as well as one fully subaqueous pyroclastic edifice and two additional, but ephemeral, islands. Sigurdur Thorarinsson identified tephra jetting and continuous uprush as characteristic types of subaerial explosive activity of Surtseyan volcanism. Subaerial cone-forming deposits of Surtseyan volcanism are typically poorly sorted, with fine-grained beds rich in sideromelane ash fragments, punctuated by larger, ubiquitously composite bombs, whereas deposits sampled by coring deep into the submarine edifice include fines-poor horizons dominated by vesicular coarse sideromelane ash. Here, we present new textural data and highlight the diversity of pyroclasts and microtextures from Surtsey (Surtur I and Surtur II) and its satellite vents (Surtla, Syrtlingur and Jolnir), in the context of Surtseyan volcanism. We used several sample sets. Some were collected during the 3.5-year long eruption and were conserved in the Icelandic Natural History Museum, including one sample from the core drilled into Surtsey in 1979. Other samples were collected during more recent field campaigns on Surtsey Island. In closing, we discuss the implications of this diversity for the range of activity and products produced by Surtsey.
Employees burnout and intention to leave: In set of banking organizations in Pakistan

This paper provides a comprehensive overview of employees’ burnout in set of banking organizations and how this burnout constitutes the intentions to leave the organization. The purpose of this study is to investigate the relationship between the factor of burnout and its causal effect as intention to leave. Our sample consists of 126 respondents from the set of banking organizations like HBL, UBL, NBP, Allied Bank Ltd, Bank Al-Habib Ltd, MCB Bank, Bank Alfalah Ltd, Faisal Bank, Meezan Bank Ltd, Pak-Askari Bank, Silk Bank and Standard Charter. The present study found out the positive relationship between the employees burnout and intention to by using regression and correlation analysis. A significant impact has been observed for independent variable burnout (job demand, exhaustion, social support and job security) over dependent variable as intention to leave. It depicts that if there exist burnout among employees the intention to leave organization would raise and vice versa.
CMOS resonant oscillators RTWO based on transmission lines

Rotatory traveling wave oscillator (RTWO) is an innovative transmission-line technique for gigahertz-rate clock signal generation and/or distribution in high-performance microprocessors and systems communication. Currently the resonant RTWO are made in the upper level of metal of a typical CMOS process; however, due the increasing of metal levels in submicron manufacturing technologies, and operation frequencies at GHz range, the parasitic elements of interconnections increase also, causing a degradation in the performance of the RTWO. In this paper a set of 5GHz low-power resonant oscillators RTWO based on transmission lines are presented. Simulation results of the RTWO including discontinuities and without them designed with a UMC 180 nm Mixed-Mode Single-Poly 6-Metal (1P6M) P-Substrate, RFCMOS fabrication process, and the High Frequency Structural Simulator (HFSS) for extraction of parasitics, are shown.
Dynamic Behaviour of LVL-Concrete Composite Flooring Systems

An LVL-concrete composite floor (LCC) is a hybrid flooring system, which was adapted from a timber-concrete composite (TCC) floor system. By replacing the timber or glulam joists with LVL joists, the strength of the floor was increased. However, the demand nowadays is to build longer spans and this may reduce the stiffness and lead to the floor being more susceptible to vibration problems. While the vibration problem may not be as critical as other structural issues, people could feel sick and not comfortable if the floor vibrates at the resonant frequency of the human body. Hence, this research focuses on the dynamic behaviour of long span LCC flooring systems. Experimental testing and finite element modelling was used to determine the dynamic behaviour, with particular regard to the natural frequency, fn and mode shape of an LCC floor. Initially, a representative series of LVL-concrete composite specimen types were built starting from (1) full-scale T-joists specimens, (2) reduced-scale (one-third) multi-span T-joists specimens and (3) reduced-scale (one-third) 3m x 3m floor. The specimens were tested using an electrodynamic shaker. The SAP 2000 finite element modelling package was used to model and evaluate the full- and reduced-scale LVL-concrete composite T-joist experimental results. Additionally, a 8m x 7.8m LCC floor was modelled and analysed using SAP 2000. The behaviour of the 8m LCC floor was investigated through the changing of (1) concrete topping thickness, (2) depth of LVL joists, (3) different types of boundary conditions, and (4) the stiffness of the connectors. Both the experimental results and the finite element analyses agreed and showed that increased stiffness increased the natural frequency of the floor, and the boundary conditions influenced the dynamic behaviour of the LCC floor. Providing more restraint increased the stiffness of the floor system. The connectors' stiffness did not influence the dynamic performance of the floor. The study outcomes were based on a 8 Hz natural frequency limitation where the fundamental natural frequency of the LCC floor must exceed 8 Hz in order to prevent vibration problems. The research showed that a 8m LCC long span floor can be constructed using LVL joists of between 300 mm to 400 mm depth with a concrete thickness of 65 mm for the longer spans, and joists of between 150 mm to 240 mm depth in conjunction with a concrete topping thickness of 100 mm for the shorter spans.
Sirtuin 1 participates in intervertebral disc degeneration via the nicotinamide phosphoribosyl transferase/nicotinamide adenine dinucleotide/sirtuin 1 pathway responsible for regulating autophagy of nucleus pulposus cells

Disc degeneration is the main cause of discogenic low back pain, disc herniation, degenerative stenosis of spinal canal, lumbar spondylolisthesis and other diseases. In the process of intervertebral disc degeneration, water and extracellular matrix of nucleus pulposus tissues are lost, so the normal tension in the intervertebral disc cannot be maintained, which worsens the living environment of nucleus pulposus cells. Low back pain (LBP), with a high incidence rate of disability, has become an increasing health concern and a social and economic problem. The present study aimed to analyze the action mechanisms of nicotinamide phosphoribosyl transferase (Nampt) and sirtuin 1 (SIRT1) in intervertebral disc degeneration (IVDD). In total 26 patients with lumbar disc herniation who had surgical resection at The Third Affiliated Hospital of Jinzhou Medical University were recruited as the experimental group and their degenerative nucleus pulposus (DNP) tissues of intervertebral disc were collected. In addition, nucleus pulposus tissues of intervertebral disc were collected from 20 patients with burst fracture of lumbar spine at the same hospital (control). Nucleus pulposus cells from primary culturing were separated for subsequent experimentation. LC3 II/I, beclin-1, SIRT1 and NAMPT mRNA and protein expression levels were determined using reverse transcription-quantitative PCR and western blotting, respectively. Nicotinamide adenine dinucleotide (NAD) contents in nucleus pulposus cells was determined by NAD assay kit. The mRNA and protein expression levels of SIRT1 in DNP tissues were reduced compared with the control tissues and decreased with increasing disease severity. The expression of autophagy-associated LC3 II/I and beclin-1 in DNP tissues was reduced compared with control tissues. SIRT1 regulated the LC3 II/I and beclin-1 expression levels in nucleus pulposus cells. Treatment with resveratrol and inhibitor of SIRT1 showed that Nampt/NAD+/SIRT1 pathway participated in the process of IVDD by regulating autophagy of nucleus pulposus cells. SIRT1 serves a role in the process of IVDD through Nampt/NAD+/SIRT1 pathway that regulates autophagy of nucleus pulposus cells. SIRT1 may become a biological target for the treatment of IVDD.
Reconstruction of cleft palate with bone morphogenetic protein in sheep: a feasibility pilot study

Introduction : Surgical repair of cleft palate with a bony bridge may offer some distinct advantages including a lower rate of fistula formation. The goal of this study was to evaluate the feasibility of surgically inducing cleft palate and reconstruction of the cleft with the use of bone morphogenetic protein-2 (BMP-2) in sheep. Materials and Methods : In the control group (two sheep), the cleft palate was repaired with standard von Langenbeck technique. In the study group (two sheep), the cleft was repaired with the same technique with the exception that aBMP-2 gel was placed between the two oral and nasal layers. Two months after cleft repair surgery, animals were sacrificed and the cleft sites were evaluated histologically with the use of light microscopy. Results : The results showed that surgically inducing cleft palate and repairing the cleft is feasible in sheep. Microscopic evaluation showed no bone formation in control group and minor bone formation in the study group. Conclusion : To determine whether BMP-2 is a useful adjunct to standard cleft palate repair techniques, an animal study with larger population is required.
International Students’ Academic and Social Integration Stories

This research report has the purpose to inform the audience about the methodological qualitative part of a study being conducted in a Hungarian university. In the last decade the Hungarian government has created opportunities for internationals to fit into the internationalization trend in education. Following these initiatives through the lens of the students is a convenient form to understand the impact of its application. The university where the study is conducted has a good reputation and of preference for international prospect students, becoming the ideal spot to research about the process of integration of international students in two aspects, academic and social. The understanding of this thematic required information collected through qualitative interviews which were conducted with students from different faculties, countries, majors, and levels of study. The findings revealed that students are satisfied in terms of social integration and gaps are found to fulfill their academic integration. The information is a relevant and important source of input for educational organizations in Hungary which are working continuously to increase the enrollment of international students, especially in the pandemic situation.
Accuracy of Stroke Volume Estimation via Reservoir Pressure Concept and Three Element Windkessel Model

Abstract Accurate stroke volume (SV) measurements can convey large amounts of information about patient hemodynamic status. However, direct measurements are too invasive in clinical practice and current procedures for estimating SV require specialised devices. This study presents an analysis of the accuracy of SV estimation by combining pulse-wave and windkessel analyses. What makes this study different to existing pulse-contour analyses is that pressure contour variation due to altered arterial mechanical properties (resistance, characteristic impedance and compliance) were related to correct corresponding pressure zones, enabling this model to more accurately capture SV from aortic pressure measurements alone. Using data from three porcine experiments, the median difference between measured and estimated SV was 1.4 ml with a 90% range (5 th -95 th percentile) -11.3ml - 12.2ml. This result relies on an estimate of the average value of just one windkessel parameter. The presented method demonstrates that SV can be estimated from pressure waveforms alone, without the need for identification of complex physiological metrics where strength of correlations may vary from patient to patient.
From Detection Through Repair: Vehicle Emissions Testing in the San Joaquin Valley

Vehicle emissions testing, otherwise known as Inspection and Maintenance (I/M), is prevalent in areas of the United States with poor ambient air quality, because tailpipe emissions are the largest single source of ozone-forming pollutants. Even though California has the most stringent emissions requirements and the largest I/M program in the nation, as of 2011, nine of California’s fifteen Air Basins failed to meet the ground-level ozone National Ambient Air Quality Standards. Where the official California Smog Check program has failed to reduce tailpipe emissions sufficiently, private organizations have stepped in. One such organization, Valley Clean Air Now (Valley CAN), a non-profit advocacy group, has offered through its Tune In & Tune Up (TI&TU) Program free emissions-testing and up to $500, per vehicle, towards emissions-related repairs. Valley CAN targets vehicle owners in the San Joaquin Valley who may be driving while unregistered because of the expense of proper repairs. In this dissertation, I use those vehicles that attended TI&TU events from 2005 through 2009 to analyze three aspects of vehicle emissions testing in California: the detection of gross polluting vehicles, the Valley CAN program’s cost-effectiveness, and the durability of emissions-related repairs. For each of the 2,048 vehicles, I have crosssectional data that includes detailed vehicle-specific characteristics, emissions test results, registration history, and the emissions-related repair cost. Vehicles participating in the TI&TU program are an unusual subset within the California fleet. The largely homogenous TI&TU fleet tends to be older and to have higher

Rising Stars - Investigating support for early career film, video and digital media practitioners in South Australia.

The study investigates the adequacy of government-funded support for early career film, video and digital media practitioners in South Australia and explores literature and government policies in the area. A multiple case study approach is then used to examine how a sample of talented and successful creative practitioners, utilise government-funded support to assist in the creation of screen-based work. The research analyses qualitative data obtained from semi-structured interviews and work histories, as well as quantitative data drawn from income level surveys. The investigation considers: the type of government-funded support utilised; the adequacy of this support; any alternative forms of support utilised; and the impact on early career development. The paper concludes that Government-funded support for early career practitioners in South Australia is not adequate to support talented practitioners who want to earn a fulltime living in the industry.
Investigating the Impact of the Washing Steps of Layered Double Hydroxides (LDH) on the Electrochemical Performance

The washing of layered double hydroxides (LDH) material is mostly purposed to discard the unreacted products after the reaction has been completed. However, this study demonstrated that the washing stage can also be targeted to optimise the electrochemical performance of LDH by using an appropriate solvent. Solvents, namely, ethanol, acetone, and an ethanol–acetone solution (2:1) were used for the washing of LDH and the impacts thereof on the structural, physical, chemical, morphological, and electrochemical properties were investigated. Using Williamson–Hall analysis, we observed modifications on the crystalline domain. The specific surface area and pore parameters for all the samples were also differently affected. The Fourier transform infrared (FTIR) measurements displayed evident changes in the basic sites. The electrochemical performances of samples were analysed. The sample washed with the ethanol–acetone solution exhibited a specific capacitance of 1807.26 Fg−1 at 10 mVs−1, which is higher than that of other samples as well as low internal resistance compared to its counterpart. This demonstrates that the use of an appropriate solvent during the washing stage of LDH affects the electrochemical properties.
The Correlation of Mouse Double Minute 4 (MDM4) Polymorphisms (rs4245739, rs1563828, rs11801299, rs10900598, and rs1380576) with Cancer Susceptibility: A Meta-Analysis

Background Mouse double minute 4 (MDM4) has been extensively investigated as a negative regulator of P53, its negative feedback loop, and the effect of its genetic polymorphisms on cancers. However, many studies showed varying and even conflicting results. Therefore, we employed meta-analysis to further assess the intensity of the connection between MDM4 polymorphisms and malignancies. Material/Methods We searched eligible articles in 5 databases (Cochrane Library, PubMed, Web of Science, Wan Fang Database, and China National Knowledge Infrastructure) up to August 2021. Odds ratios (ORs) and 95% confidence intervals (CIs) were utilized to probe the correlation of 5 MDM4 polymorphisms (rs4245739, rs1563828, rs11801299, rs10900598, and rs1380576) with carcinomas. We employed meta-regression and subgroup analysis to probe for sources of heterogeneity; Funnel plots, Begg’s test, and Egger’s test were used to evaluate publication bias. Sensitivity analysis was applied to assess the stability of the study. Results Twenty-two studies, comprising 77 reports with 29 853 cases and 72 045 controls, were included in our meta-analysis. We found that rs4245739 polymorphism was a factor in reducing overall cancer susceptibility (dominant model, OR=0.85, 95% CI=0.76–0.95; heterozygous model, OR=0.86, 95% CI=0.78–0.96; additive model, OR=0.87, 95% CI=0.79–0.95), especially in Asian populations, and it also reduces the risk for esophageal squamous cell carcinoma (ESCC). The remaining 4 SNPs were not associated with cancers. Conclusions The rs4245739 polymorphism might reduce the risk of malignancies, especially in Asian populations, and it is a risk-reducing factor for ESCC incidence. However, rs1563828, rs11801299, rs10900598, and rs1380576 are not relevant to cancer susceptibility.
Hidden Consequences: Examining the Impact of NIL on Athlete Well-Being

With the NCAA's NIL policy changes, many athletes will likely need to solve the issue of brand management, with many of them assuming the role themselves. Taking on this role will likely lead to even more investment in their athlete identity (i.e., role engulfment), which has negative consequences for the athlete (Hatteberg, 2020). Guided by the literature on role engulfment, this article investigates the hidden effects NIL may have on collegiate athletes and their well-being, along with various branding and legal implications.
Design of Shunt Electric Networks in View of Sound Absorption with Loudspeakers

Variable acoustic properties can be obtained at the diaphragm of a loudspeaker, with the help of very basic control strategies, among which is the simple electrical shunting of the transducer. These shunt techniques have been demonstrated to present singular similarities with active acoustic feedback strategies, dedicated to the control of the acoustic impedance of the loudspeaker. Based on this observation, an interesting strategy has been developped, intending at designing electric networks which, when connected to the loudspeaker, can make the latter reach a desired acoustic impedance over a certain frequency badnwidth. This paper presents a methodology for designing electric networks, that can be either passive or active, capable of achieving variable sound absorption at the loudspeaker diaphragm. In a first part, the theory underlying the concept of "electroacoustic absorber" is provided, highlighting formal equivalences between shunt and active feedback control, especially through the introduction of equivalent electric networks that mimic the performances of acoustic feedbacks. Simulated acoustic performances are presented, followed by discussions on the design of active electric shunts in view of active sound absorption. At last, experimental assessments of the studied configurations are presented, with general discussions on the potential improvements and applications.
