The analysis of this field shows that the need to innovate added to scientific development has established networks that overcome geographical boundaries in the knowledge dissemination. Researchers need to share their research outputs with broader audiences on a larger scale. It is necessary to communicate science in a more attractive and effective way.
Measuring the interaction between bassoon and horn players in achieving timbre blend

Our study investigates the interactive relationship between bassoon and horn players in achieving timbre blend during musical performance. The interaction is studied in a behavioral experiment, measuring the timbral adjustments performers employ. Several timbre descriptors serve as acoustic measures, quantifying global and formant-based spectral-envelope properties. Furthermore, musicians’ selfassessment of their performances is measured through behavioral ratings. The performances are investigated across four factors, i.e., room acoustics, communication directivity, musical voicing, and leading vs. accompanying roles. Findings from ANOVAs suggest that differences in role assignments and communication directivity between performers lead to timbral adjustments. These effects are more pronounced for horn than for bassoon and performer interdependencies appear to be most important for unison voicing.
Time to Blood Culture Positivity: An Independent Predictor of Mortality in Streptococcus Pyogenes Bacteremia

Abstract Background Streptococcus pyogenes bacteremia is a severe condition with high mortality. Time to blood culture positivity (TTP) is known to predict the outcome in bacteremia with other pathogens. This study aimed to determine the association between TTP and outcome in S pyogenes bacteremia. Methods This retrospective observational cohort study comprised adults with S pyogenes bacteremia, identified through the laboratory database between 2015 and 2018, in the Region of Skåne, Sweden. Correlations between TTP and outcomes were investigated. Primary outcome was death within 30 days, and secondary outcomes were presence of sepsis or disease deterioration within the first 48 hours. Results A total of 347 episodes of S pyogenes bacteremia were identified, of which 61 were excluded, resulting in 286 included episodes. Median TTP was 10.4 (interquartile range, 8.4–11.4) hours. Thirty-day mortality was 10%. Median TTP was shorter in patients who died within 30 days compared to survivors (8.6 vs 10.4 hours; P < .001). In a multivariable logistic regression, shorter TTP was associated with 30-day mortality when adjusting for age, Charlson Comorbidity Index, and focus of infection (odds ratio, 3.7 [95% confidence interval, 1.2–11.3]; P = .02). There was no statistically significant difference in TTP between patients with sepsis within 48 hours and those who did not have sepsis. Additionally, there was no statistically significant difference in TTP between patients with disease deterioration compared to those who did not deteriorate. Conclusions Knowledge on TTP might be a tool to determine the prognosis of a given patient with S pyogenes bacteremia.
The technology of TEM tunnel prediction imaging

In order to solve the problem of fast and effective detection of the water-bearing structure ahead of tunnel wall,we try to introduce the transient electromagnetic method(TEM),which is sensitive to water-bearing structures,into tunnel condition working.In this paper,we give the TEM tunnel prediction configuration.After analyzing the special condition of tunnel location,we introduce "moving plate" theory and create the imaging system of TEM prediction based on the parameter of secondary differential conductivity.We deduce the non-linear function of conductivity and magnetic response excited by imaginary equivalent plate source.By introducing an auxiliary parameter,we obtain the parameter of conductivity by using Genetic algorithm.We at last draw the imaging section with the parameter of secondary differential conductivity.Numerical simulation of thin layer model and the survey of a tunnel has been carried out.Both results of modeling and survey show that it is effective and successful to use TEM imaging method to explore the unfavorable geology body in tunnel.
The Interplay between Autophagy and Redox Signaling in Cardiovascular Diseases

Reactive oxygen and nitrogen species produced at low levels under normal cellular metabolism act as important signal molecules. However, at increased production, they cause damage associated with oxidative stress, which can lead to the development of many diseases, such as cardiovascular, metabolic, neurodegenerative, diabetes, and cancer. The defense systems used to maintain normal redox homeostasis plays an important role in cellular responses to oxidative stress. The key players here are Nrf2-regulated redox signaling and autophagy. A tight interface has been described between these two processes under stress conditions and their role in oxidative stress-induced diseases progression. In this review, we focus on the role of Nrf2 as a key player in redox regulation in cell response to oxidative stress. We also summarize the current knowledge about the autophagy regulation and the role of redox signaling in this process. In line with the focus of our review, we describe in more detail information about the interplay between Nrf2 and autophagy pathways in myocardium and the role of these processes in cardiovascular disease development.
CORPORATE GOVERNANCE TRAITS AND CORPORATE RISK REPORTING OF LISTED NIGERIAN FINANCIAL SERVICES FIRMS

The study used an ex-post facto research design to determine the effect of corporate governance traits on the corporate risk reporting of Nigerian publicly traded financial services firms. The population of research was comprised of all fifty-two (52) publicly traded financial services companies in Nigeria as at October 2021. To sample thirty-nine (39) publicly traded financial services companies, a judgmental sampling approach was used. Secondary data was taken from annual reports and financial statements of selected Nigerian publicly traded financial services companies for five (5) fiscal years covering 2015–2019 and analyzed using multiple regression analysis. The findings demonstrate a favorable association between the size of the board of directors and corporate risk reporting by Nigerian financial businesses. While independent directors and board gender have no effect on the corporate risk reporting of Nigerian financial services companies. Board activity and profitability have an inverse relationship with corporate risk reporting of Nigerian financial firms. Finally, the research establishes a positive correlation between business size and financial services companies' corporate risk reporting in Nigeria. It is recommended that the regulatory bodies formulate laws relating to risk governance that will enhance corporate risk reporting in Nigeria. Also, the number of independent and female directors should be increased so as to have more influence on decisions that can increase risk reporting transparency.
Does Mindfulness Influence Academic Performance? The Role of Resilience in Education for Sustainable Development

A mindful person is prone to be open to novelty, attentive to distinctions, sensitive to context, aware of multiple perspectives, and focused on the present. Therefore, the role of mindfulness in educational contexts is gaining ground given the great possibilities it offers in developing students’ competences in education for sustainable development (ESD). The main goal of this study is to explore how mindfulness plays a key role in the learning process in response to the need to develop students’ emotional competencies in ESD, and specifically how mindfulness has an impact on academic performance through resilience. We tested the research model with a questionnaire addressed to 497 students from three higher education institutions and one secondary school. The results of a structural equation analysis confirm the study hypotheses. We find mindfulness is positively related to resilience, which leads to better academic performance. Thus, being mindful is a key competence in ESD since it allows young people to face their education with the highest possibilities of training, experience, and personal growth. This exploratory study offers further evidence of the need to invest in mindfulness to foster resilience and academic performance and represents a first step for designing additional interventions on this line.
Tunable laser module for fibre optic communications

This thesis deals with the design, realisation, and testing of the wavelength tunable 1540-nm laser modules that are intended for fibre optic communications. The short external cavity laser uses an electrically controlled silicon micromachined FabryPerot interferometer (FPI) device as the tuning element. First, the most common techniques for the diode laser wavelength tuning and applications for these devices are reviewed. Then the ways of coupling laser power into the single-mode (SM) optical fibre are considered and the characteristics of the fibre attachment methods are studied. The design, assembly and testing of three prototypes is introduced. Their discontinuous tuning spans range between 8 and 13 nm and their output power between 100 and 570 μW. The modules produce multimode tuning having an rms spectral width of about 1 nm. In addition, one prototype is capable of singlemode tuning with a side mode suppression ratio of 26 dB. The measured wavelength span is threefold compared to our earlier work near 980 nm and the widest reported single-mode tuning range obtained from a short external cavity FabryPerot diode laser without temperature tuning. This is also the first directly modulated external cavity laser that has a 3dB bandwidth of over 600 MHz. The study confirms that it is possible to realise the laser-to-SM-fibre coupling using adhesive bonding. Further studies are needed in order to improve the speed and repeatibility of the assembly process together with the long-term reliability of the fibre attachment. The prototype test results show that the FPI-tuned diode lasers have potential for applications where moderate performance suffices and low cost is mandatory. The hybrid arrangement uses standard laser components and therefore can
Farm Vehicle Following Distance Estimation Using Deep Learning and Monocular Camera Images

This paper presents a comprehensive solution for distance estimation of the following vehicle solely based on visual data from a low-resolution monocular camera. To this end, a pair of vehicles were instrumented with real-time kinematic (RTK) GPS, and the lead vehicle was equipped with custom devices that recorded video of the following vehicle. Forty trials were recorded with a sedan as the following vehicle, and then the procedure was repeated with a pickup truck in the following position. Vehicle detection was then conducted by employing a deep-learning-based framework on the video footage. Finally, the outputs of the detection were used for following distance estimation. In this study, three main methods for distance estimation were considered and compared: linear regression model, pinhole model, and artificial neural network (ANN). RTK GPS was used as the ground truth for distance estimation. The output of this study can contribute to the methodological base for further understanding of driver following behavior with a long-term goal of reducing rear-end collisions.
Evaluation of WRF Cumulus Parameterization Schemes for the Hot Climate of Sudan Emphasizing Crop Growing Seasons

High spatiotemporal resolution climate data are essential for climate-related impact studies. The Weather Research and Forecasting (WRF) model is widely used to downscale climate data for different regions with regional-specific physics configurations. This study aimed to identify robust configurations of the WRF model, especially cumulus parameterization schemes, for different climatic zones of Sudan. We focused on wet season (June–September) rainfall and dry season (November–February) temperature, which are determinants of summer crop and irrigated wheat yields, respectively. Downscaling experiments were carried out to compare the following schemes: Betts–Miller–Janjic (BMJ), improved Kain–Fritch (KFT), modified Tiedtke (TDK), and Grell–Freitas (GF). Results revealed that the BMJ performed better for wet season rainfall in the hyper-arid and arid zones; KFT performed better for rainfall in July and August in the semi-arid zone where most summer crops are cultivated. For dry season temperature, the BMJ and TDK outperformed the other schemes in all three zones, except that the GF performed best for the minimum temperature in December and January in the arid zone, where irrigated wheat is produced, and in the semi-arid zone. Specific parameterization schemes therefore need to be selected for specific seasons and climatic zones of Sudan.
Ingestion of Diazotrophs Makes Corals More Resistant to Heat Stress

Over the past decade, coral bleaching events have continued to recur and intensify. During bleaching, corals expel millions of their symbionts, depriving the host from its main food source. One mechanism used by corals to resist bleaching consists in exploiting food sources other than autotrophy. Among the food sources available in the reefs, dinitrogen (N2)-fixing prokaryotes or planktonic diazotrophs (hereafter called ‘PD’) have the particularity to reduce atmospheric dinitrogen (N2) and release part of this nitrogen (diazotroph-derived nitrogen or DDN) in bioavailable form. Here, we submitted coral colonies of Stylophora pistillata, fed or not with planktonic diazotrophs, to a temperature stress of up to 31 ± 0.5 °C and measured their physiological responses (photosynthetic efficiency, symbiont density, and growth rates). Heat-unfed colonies died 8 days after the heat stress while heat-PD-fed corals remained alive after 10 days of heat stress. The supply of PD allowed corals to maintain minimal chlorophyll concentration and symbiont density, sustaining photosynthetic efficiency and stimulating coral growth of up to 48% compared to unfed ones. By providing an alternative source of bioavailable nitrogen and carbon, this specific planktonic diazotroph feeding may have a profound potential for coral bleaching recovery.
Two dimension versus three dimension ultrasound assessment of caesarean section scars

Background: Ultrasound (US) is now used as an imaging modality for the evaluation of lower uterine segment (LUS). A number of reports of sonographic evaluation of LUS have appeared in literature. It has been speculated that thickness of the LUS is related to the quality of wound healing. There is strong correlation between the anatomic status of scarred LUS as assessed by USG and its functional status which is tested during labour. Objective: The aim of this work was to investigate the accuracy of two-dimensional and three-dimensional ultrasound in measurement of Caesarean section scar thickness. Patients and methods: This study was cross sectional study, conducted in Aswan University Hospital. The ultrasound examinations were conducted in the Obstetrics and Gynecology department between June 2017 and September 2021. The study included 150 pregnant females with previous one or two cesarean sections (CS) (aged 20-41y; mean 32.5y), underwent TA 2D and 3D US for assessment of the LUS thickness at 37-39 gestational weeks, before planning.
Influence of Continuous Cropping on Yield and Quality of Flue-cured Tobacco

year fixed\|site field trial was conducted to study the influence of continuous cropping on the yield and quality of flue\|cured tobacco. The results showed that 1) the growth vigor of tobacco plant, yield, output value, average price, and the proportion of the superior and medium tobacco leaves after continuous cropping were significantly decreased; 2) while continuous cropping had negative effect on chemical components and smoking quality of tobacco, the effect lagged behind that on the growth of tobacco plant, yield and output value; and 3) the 3 tested measures had little effect on improving the continuous cropped field.
Factors affecting SMEs growth: the case of the real estate valuation service industry

Research background: Based on the literature, several ways of assessing the conduct of business and a number of factors influencing the growth and development of the companies can be identified. However, the diversity of business entities and their business environment raises the importance of considering the unique nature of the industry in the selection of performance measures. Our research focuses on real estate valuation firms that provide information and consulting services to real estate markets. Purpose of the article: As professional practice shows, there are different business models for property valuation. These businesses differ in their organisational and legal form and the type of valuations performed, the type of client served, or the scope of services provided. The main purpose of the research is to identify factors that significantly affect the development odds of valuation companies in Poland, especially the growth of income. Methods: The study was based on data collected from the survey of Polish real estate valuers. The analysis was conducted on a sample of 277 professionals who own valuation companies and were certified no later than the end of 2014. A quantitative analysis using a logistic regression model was conducted to identify the factors that influence the prospects for valuation business growth. Findings & value added: The research confirms the relationship between the way of conducting real estate valuation activities and its development chances. The most important factors are a spatial and substantive range of services, cooperation and employment, and clients' profile. Demographic characteristics were also found to be significant. Although the results presented here are based on data from the real estate valuation industry, their relevance is much broader. The findings provide a better understanding of the factors that influence the performance and success of SMEs, particularly in the information and consulting industry.
Learning Through SMS in Saudi EFL Classroom: An Inter-University Study of Learner Perceptions and Achievement of Autonomy

Technology as a learning tool or otherwise holds great attraction for learners today. The current study explored the impact of Short Messages as Learning Tool (SMLT) on EFL Saudi learners learning confused English words. It also gauges learners' satisfactions towards using such tools on their autonomy and language proficiency. The study pursued a quasi-experiment research design. It recruited 80 EFL learners across Najran University and Qassim University, KSA. To ensure parity of existing language proficiency and learning success, the Oxford Placement Test is administered once before and once at the end of the intervention to all of the 80 participants to obtain comparative values. Furthermore, a semi-structured interview is also used with three randomly selected participants from each of the experimental groups to obtain data on individual perceptions of the EFL learners to the use of MALL in the EFL classroom. Content analysis is used to identify dominant themes in these. Findings revealed that learners acquisition for confusing words were developed to a great extent in both universities. Moreover, the study found that there is no significant difference in the students' achievement attributed to the learning sittings, Z = . 935. Finally the students expressed satisfaction in terms of their autonomy ratings and complementary points of view on the use of SMS, based on the semi-structured interviews. The current research is useful as its findings can apply to mobile teaching and text messaging in the English classroom for EFL curriculum developers and English language teachers.
Evaluation of Proanthocyanidin-based dentifrices on dentin-wear after erosion and dental abrasion - In situ study

Background Proanthocyanidin has been considered as a preventive agent against erosion because of its properties, which involves remineralization, reduction of demineralization and matrix metalloproteinases (MMPs) inhibition. Thus, the aim of this in situ study was to evaluate the effect of proanthocyanidin-based dentifrices on wear resistance of dentin specimens subjected to erosion associated with abrasion. Material and Methods This crossover double-blinded study was performed in 5 phases of 5 days each, with 10 healthy volunteers who wore 5 palatal devices (1 for each phase) with 4 dentin specimens. The groups under study were: G1 – placebo dentifrice (negative control group); G2 – 0.012% chlorhexidine dentifrice (1st positive control group); G3 – NaF 1110 ppm fluoride dentifrice (2nd positive control group); G4 – 10% purified proanthocyanidin dentifrice (1st test group); G5 – fluoride + proanthocyanidin dentifrice (2nd test group). Erosion was performed by palatal device immersion in acid beverage (Coca-cola®), 3 times daily for 5 minutes during 5 days. Abrasion was applied after the first and third erosive cycles by using a eletric toothbrush during 15 seconds in each specimen with the application of the studied dentifrices slurry. The response variable was depth of dentin loss (µm) measured by profilometry. Data were analyzed by Repeated Measures Analysis of Variance followed by LSD Fisher’s test (p<0.05). Results Data (G1: 1.76 ± 0.55A; G2: 1.19 ± 0.42B; G3: 1.29 ± 0.34B; G4: 0.93 ± 0.38C; G5: 0.82 ± 0.34C) showed that G4 and G5 did not presented significant difference between them, but showed less dentine loss when compared to all other groups. G1 presented the highest dentin wear. Conclusions Proanthocyanidin and the combination of proanthocyanidin and fluoride dentifrices revealed the best results, showing that these formulations could be a promising alternative for patients who suffer with dentin erosion. Key words:Dentin, erosion, cross-liking agent, metalloproteinases, toothpastes.
