Published: August 2022

AbstractHerein, a carbon paste electrode (CPE) modified with poly(reduced-o-nitrobenzoic acid [r-o-NBA]) supported in graphene quantum dots (GQDs) was fabricated for the first time. The fabricated electrode’s surface morphology and composition were characterised by scanning electron microscope and transmission electron microscope. The poly(r-o-NBA)/GQDs/CPE showed high electrocatalytic activity towards the oxidation of naproxen (NPX) using cyclic and differential pulse voltammetric methods. The effect of scan rate on the oxidation peak of NPX suggests that the electrode process was typically diffusion-controlled. In addition, the effect of pH reflects the participation of protons in the oxidation process of NPX. The peak current is linearly proportional to the concentration of NPX ranging from 1.0 to 100.0 µM, with the correlation coefficient (R2), sensitivity, limit of detection (3σ), and limit of quantification (10σ) being 0.9995, 0.419 µA·µM−1·cm−2, 0.672, and 2.241 µM, respectively. Using chronoamperometry, the diffusion coefficient of NPX at the poly(r-o-NBA)/GQDs/CPE was estimated to be 5.36 × 10−6 cm2·s−1. The proposed electrode has good reproducibility, stability, and high selectivity for NPX oxidation. The obtained recovery range (96.7–102.0%) means that the proposed sensor performed satisfactorily when applied for the detection of NPX in its pharmaceutical formulations.

Published: August 2022

Abstract
As an effective method of studying soil anisotropy, hollow cylinder torsional shear (HCTS) tests have been performed extensively on sedimentary soil, thereby establishing the anisotropic behavior of sand and clay. However, little is known about the anisotropic behavior of granite residual soil (GRS) formed by weathering, partly because hollow cylindrical specimens of natural GRS have yet to be prepared successfully, hence the lack of HCTS tests performed on GRS. The unique geotechnical properties of GRS, including high intact strength, susceptibility to disturbance, and the minor fissures in soil, pose great challenges when trying to prepare natural specimens. This paper proposes a new method to address this issue, which involves preparing a solid cylindrical specimen, drilling an initial inner cavity and then enlarging it, and finely trimming the specimen to its ultimate dimensions. Two methods are proposed for enlarging the inner cavity, both of which work well. The reliability of the proposed method is confirmed through specimen quality as indicated by the limited void ratio change due to reconsolidation, test repeatability, and comparison of the results of HCTS tests with those of triaxial tests. The HCTS tests reveal the shear strength anisotropy of natural GRS. Although specified for residual soil derived from granite, the proposed method could also be used for other weathered materials.

Published: August 2022

Abstract
In the past, the power consumption behavior of customers was not considered, so the research of power consumption behavior based on artificial intelligence technology was put forward. Combined with artificial intelligence technology, the structure block diagram of electricity consumption analysis is constructed to complete multivariable and multidimensional data storage and management. The initial cluster center is randomly selected from the sample data set to determine the distance between the sample point and the cluster center. Based on the reasonable evaluation index of electric power behavior, the analysis model of electric power consumption behavior is established. The data set is divided by similarity measure, the fuzzy weighted index is initialized, the membership matrix is initialized and updated, the objective function is calculated, and the types of data objects are determined according to the calculation results. Based on this, the user screening process for abnormal power consumption is designed. The k-means clustering algorithm is used to design the diagnostic analysis process, and the closed-loop diagnostic mechanism for abnormal electricity consumption such as stealing and leakage is studied. Experimental results show that the proposed method can effectively distinguish the normal operation mode from the abnormal operation mode of power consumers.

Published: August 2022

Microwave heating (MHM) and mutated sol-gel (SGM) mechanisms were used to effectively create CuO samples with two dissimilar morphologies, such as nanoparticles (CuO-NPs) and nanorods (CuO-NRs), using Mussaendafrondosalinn plant extract as the bio-reducing operator. X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray (EDX) investigations were used to analyze the sample's structure, pureness, and morphological characteristics. UV-Visible diffuse reflectance (DRS) and photoluminescence (PL) spectroscopy methodologies were used to analyze optical properties and calculate bandgap energy. The bandgap of the samples was measured using the Kubelka-Munk mechanism, and it was found to be 2.74eV and 2.33eV for CuO-NPs and CuO-NRs, correspondingly. CuO-NPs and CuO-NRs were investigated for antibacterial activity versus each Gram-positive and Gram-negative microorganisms using a modified disc diffusion method. When correlated to the sample CuO nanorods, the antibacterial study confirms that the sample CuO nanoparticles are high-grade antibacterial agents. Using solar lighting, the photocatalytic activity of CuO nano-reactants (CuO-NPs and CuO-NRs) for the degradation of methylene blue (MB) dye was investigated, and the findings revealed that CuO-NPs with tinier particle sizes degraded MB more than CuONRs.

Published: August 2022

Abstract

Objectives
To examine 1) the contribution of physiological performance variables to Olympic-distance (OD) triathlon performance, and 2) the links between an 8-wk intensified training plus competition preceding the main OD triathlon race and the changes in the physiological status in triathletes.

Study Design
An observational longitudinal study.

Methods
Endurance performance variables during maximal incremental running and cycling tests, and average velocity during an all-out 400-m swimming performance test (V400) were assessed before (T1) and after (T2) the intensified training in 7 recreational-level triathletes.

Results
Overall main OD triathlon time was extremely largely (r = −0.94; P = 0.01) correlated with peak running velocity (PRV). Best correlation magnitude between exercise modes' partial race times and the corresponding specific physiological criterion tests was observed for swimming (r = −0.97; P < 0.001). Improvement in V400 (2.9%), PRV (1.5%) and submaximal running blood lactate concentration (17%) was observed along the training period, whereas no changes were observed in the cycling endurance performance variables. Higher volume of training plus competition at high intensity zones during cycling, running and swimming were associated with lower improvements or declines in their corresponding exercise mode-specific criterion performance variables (r = 0.81–0.90; P = 0.005–0.037).

Conclusion
Results indicate that: 1) PRV is highly associated with overall OD triathlon performance, and 2) spending much time at high relative intensities during swimming, cycling or running may lead, in a dose-response manner, to lower improvements or decreases on those exercise-specific physiological performance variables. This may favor the emergence of overreaching or diminished performance.

Authors: Krapež Katarina 
Published: August 2022

The contemporary scientific community faces significant challenges in assuring research credibility. Since the onset of the COVID-19 pandemic, there has been an even greater interest in swift publications of valid research results, and individual editors of reputable academic journals might feel pressured to ensure high quality of published papers. Aiming to explore how editors perceive their management of the quality assessment processes and to identify decisions and processes which editors believe to be the most critical for securing high-quality publications, we conducted a qualitative survey. 258 editors of scientific journals from 42 countries participated in the study. Key findings of the first part of the study show that across disciplines, editors perceived the manuscripts as excellent if they were innovative, scientifically sound, well-written and well-argued, addressed a significant topic, contained useful results, and had the potential to change (improve) something. Secondly, originality emerged as the leading quality criteria in manuscript quality assessment, followed by validity and significance. Finally, results indicate that factors influencing the overall complexity of editorial quality assessment are: (i) clearly defined minimum threshold of required quality, (ii) consistency of assessment between individual quality criteria, and (iii) experience of the editor.

Published: August 2022

Background: Garden cress (Lepidium sativum) belongs to the Cruciferae family, a fast-growing edible herbaceous plant. This study aimed to determine the essential and non-essential metals levels and nutritional composition of garden cress seed grown in the Wolaita Zone in southern Ethiopia. The study was carried out by collecting garden cress cultivated in Jage, Wandara, Taba, Hilena, Siyara, Demba Gale, Himbecho, Afama and Gara sites of the Wolaita Zone, Southern Ethiopia. Methods: 27 triplicate garden cress seed samples were collected from nine selected sites and digested by the wet digestion method. The level of metals in the sample was determined by using FAAS. Result: The result showed that the average concentration of K, Ca, Mg, Fe, Cu and Zn in the garden cress seed samples in mg/100 g dry weight, were in the range of 1179.76 to 1226.79, 249.52 to 291.62, 314.84 to 341.44, 7.29 to 8.48, 3.72 to 5.44 and 5.80 to 6.68, respectively. The average concentration of non-essential lead metal was not detected in all sample sites. The proximate composition of the garden cress seed sample was in the range of 19.68% to 22.87% for protein, 8.30% to 10.27% for Crude fiber, 20.72% to 24.17% for fat, 3.44% to 4.63% for ash, 1.37% to 2.59% for moisture, 40.56% to 43.24% for carbohydrate and 332.96 to 344.19 Kcal/100 g for energy. The study confirmed that the garden cress seed was a good source of essential metals and an excellent source of protein, carbohydrate, fiber, energy and fat contents. The concentrations of metals in garden cress were permissible compared with recommended permissible limits of WHO/FAO as well as USDA.
The Effects of the TSOL Knot on the Repair Strength and Gliding Resistance Following Flexor Tendon Repair

Published: August 2022

Background:
The stability of a suture knot construct has been realized as an important parameter that affects the strength of flexor tendon repairs. A novel 2-strand-overhand-locking (TSOL) knot, which is not commonly used in the clinical setting, recently was reported to increase repair strength and to decrease tendon gliding resistance in a 2-strand repair technique. The purpose of the present study was to investigate the effect of the TSOL knot on tendon repair strength and gliding resistance compared with a typical surgical knot in both 2-strand and 4-strand repair techniques using an in vitro turkey flexor tendon model.

Methods:
Sixty flexor digitorum profundus tendons from the long digit of the turkey foot were divided evenly into 4 groups and repaired with the following techniques: (1) a 2-strand modified Pennington repair with a square knot, (2) a 2-strand modified Pennington repair with a TSOL knot, (3) a 4-strand grasping cruciate repair with a square knot, and (4) a 4-strand grasping cruciate repair with a TSOL knot. Repaired tendons were tested for failure mode, gliding resistance, and repair strength at failure.

Results:
The repair strength and stiffness of the 4-strand repairs were significantly higher than those of the 2-strand repairs, regardless of knot type (p < 0.05). The repair strength at failure of the TSOL knot was significantly greater than that of the square knot in 2-strand repairs (p < 0.05) but not in 4-strand repairs. The gliding resistance of the TSOL knot was significantly decreased compared with that of the square knot in both 2-strand and 4-stand repairs (p < 0.05). With regard to failure mode, the TSOL knot was less likely to fail due to knot unravelling.

Conclusions:
In this in vitro biomechanical study involving the use of turkey flexor tendons to compare gliding resistance and repair strength characteristics for knot-inside 2 and 4-strand repairs, the TSOL knot was associated with decreased repaired tendon gliding resistance, regardless of the number of strands used. Although the TSOL knot also increased the repair strength, the difference was only significant when 2-strand repairs were used. The results of our study support the use of the TSOL knot in the clinical setting of flexor tendon repair using 2 or 4-strand, knot-inside methods.

Clinical Relevance:
In surgical repair of flexor tendons, there is substantial interest in maximizing strength while minimizing friction. This study shows the potential utility of the TSOL knot to increase repair strength while decreasing gliding resistance, particularly in 2-strand repairs.

Abstract

The present study was conducted to calculate the genetic parameters for direct and maternal influences on Mecheri sheep growth features by Bayesian analysis using multi-trait animal model for designing suitable breeding application and genetic assessment methodologies. The genetic determinants for varying body weights at different ages were calculated using data from 2825 Mecheri lambs born between 2010 and 2020 that were kept in a warm and semi-arid climate. Mecheri sheep body weight (mean ± SE) at various stages viz., BW, WW and BW12 were 2.6 ± 0.01, 11.1 ± 0.05 and 20.7 ± 0.13 kg respectively. The direct estimates of heritability (± SD) for BW, WW, BW6 and BW12 were 0.21 ± 0.041, 0.21 ± 0.041, 0.12 ± 0.052 and 0.13 ± 0.053 respectively and the maternal heritability for BW, WW, BW6 and BW12 was 0.18 ± 0.021, 0.08 ± 0.023, 0.11 ± 0.022 and 0.13 ± 0.033, respectively. Estimates of maternal heritability suggests that even at later stages, there were considerable maternal effects. For several growth traits, positive estimates of additive genetic connections were observed, with values ranging from low to high. The additive genetic correlation between WW and BW6, BW9 and BW12 was 0.70 ± 0.145, 0.57 ± 0.171 and 0.50 ± 0.194. The maternal genetic correlations ranged from 0.06 ± 0.152 (BW-BW12) to 0.86 ± 0.046 (BW6-BW9) and the residual correlation increased progressively from 0.18 ± 0.034 (BW-WW) to 0.85 ± 0.013 (BW9-BW12). The medium to high estimates of heritability and genetic correlation of body weight parameters at various ages in Mecheri sheep indicated the genetic potential for all traits. In general, the features WW and BW6 both refer to the same genetic growth process, hence, it is recommended to undertake single trait selection based on weight at weaning age rather than using the present selection procedure of weight at six-month of age. By choosing the top performers from the Mecheri sheep flocks, it is possible to take advantage of the strong genetic potential for improvement in these parameters.

Abstract

Background
The timely sharing of public health information is critical during a pandemic and is an obstacle that Canada has yet to fully address. During the current Coronavirus Disease 2019 (COVID-19) pandemic, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral genome sequencing has provided a deeper understanding of transmission patterns, enabled the identification of variants of concern, and facilitated diagnostic tests and vaccine development and evaluation. The Canadian national response faces challenges in aggregating genomic contextual data and carrying out integrated analysis across regions partly due to disparities in the case report forms used to capture epidemiological and clinical data. Such variations delay data integration and make consistent analysis difficult or impossible. The objective of this work is to understand what information is being collected from severe acute respiratory syndrome coronavirus 2 case report forms used across Canada and identify potential genome sequence data harmonization issues and solutions.
Methods
Provincial/territorial/national Canadian COVID-19 case report forms were subjected to field-by-field comparisons to identify variations in data categorization, structures, formats, types, granularity, ambiguity, and questions asked. Federal epidemiologists were consulted to substantiate the results.
Results
Data harmonization issues and common data elements were identified. We make recommendations for better national coordination, integrated databases, and data harmonization tools.
Conclusion
This report compares data elements of the various case report forms used across Canada to identify overlaps and differences in the collection method of COVID-19 case information, while also highlighting data harmonization complications and potential solutions. Knowing which data elements are available to researchers and health officials will better inform the development of Coronavirus Disease 2019 surveillance and research questions.
