High-Frequency and High-Power Performance of n-Type GaN Epilayers with Low Electron Density Grown on Native Substrate

The n-type GaN epilayers with low electron density were developed on a native substrate using the metalorganic vapour phase epitaxy method and investigated under pulsed electric fields until material breakdown and optically in the spectrum range from 0.1 THz to 60 THz at two temperatures of 77 K and 300 K. The epilayers demonstrated the low-field electron mobility and density values reaching up to 1021 cm2/V·s and 1.06 × 1016 cm−3 (at 300 K) and 2652 cm2/V·s and 0.21 × 1016 cm−3 (at 77 K), respectively. Maximum injected electric power value till the damage of the GaN epilayer was found to be up to 1.8 GW/cm3 and 5.1 GW/cm3 at 77 K and 300 K, respectively. The results indicate new practical possibilities of the GaN material controlled by an external electric field.
In Vitro Genotoxicity Evaluation of an Antiseptic Formulation Containing Kaolin and Silver Nanoparticles

Worldwide antimicrobial resistance is partly caused by the overuse of antibiotics as growth promoters. Based on the known bactericidal effect of silver, a new material containing silver in a clay base was developed to be used as feed additive. An in vitro genotoxicity evaluation of this silver-kaolin clay formulation was conducted, which included the mouse lymphoma assay in L5178Y TK+/− cells and the micronucleus test in TK6 cells, following the principles of the OECD guidelines 490 and 487, respectively. As a complement, the standard and Fpg-modified comet assays for the evaluation of strand breaks, alkali labile sites and oxidative DNA damage were also performed in TK6 cells. The formulation was tested without metabolic activation after an exposure of 3 h and 24 h; its corresponding release in medium, after the continuous agitation of the silver-kaolin for 24 h was also evaluated. Under the conditions tested, the test compound did not produce gene mutations, chromosomal aberrations or DNA damage (i.e., strand breaks, alkali labile sites or oxidized bases). Considering the results obtained in the present study, the formulation seems to be a promising material to be used as antimicrobial in animal feed.
Effect of organic and inorganic fertilizers on the growth and yield of cucumber (Cucumis sativa L.)in South-South Nigeria

The experiment was conducted at the University of Port Harcourt Teaching and Research farm, Port Harcourt, Rivers State, Nigeria from April to August, 2019 on the effects of organic and inorganic fertilizers on the growth and yield of cucumber ( Cucumis sativus L). The research was done in a randomized complete block design with four treatments and replicated four times. The treatments include control (no application), NPK 15:15:15, spent mushroom substrate, and poultry manure. Data collected were, vine length (plant height), number of leaves, stem girth, leaf area, length of pod, weight of pod. Results showed that plots with poultry manure had significant effect on vine length, number of leaves, leaf area at 6 weeks after planting (WAP) and 8WAP. The highest number of fruits was 9.0 per plot or 15,000 per hectare and highest fruit weight was 1.59kg/plot (2,650kg/ha) which were higher than NPK 15:15:15 (0.47kg/plot or 783.33kg/ha) and spent mushroom substrate (0.19kg/plot or 316.67kg/ha). Hence, the use of poultry manure as organic source for the cultivation of cucumber in the study area would be recommended.
“I Am My Home”: Aged Out Foster Youth’s Discursive Constructions of Home

The present study explores how aged out foster youth discursively construct home in light of their experiences before, during, and/or after aging out of foster care. Results from 30 interviews with aged out foster youth revealed three primary themes represented participants’ sensemaking around home: home as a place (where), home as family, and home as self. The current study offers unique theoretical and practical implications for researchers and professionals who work with foster youth during their transition out of care. Limitations and directions for future research are presented.
How to date a crocodile: estimation of neosuchian clade ages and a comparison of four time‐scaling methods

Clade ages within the crocodylomorph clade Neosuchia have long been debated. Molecular and morphological studies have yielded remarkably divergent results. Despite recent advances, there has been no comprehensive relative comparison of the major time calibration methods available to estimate clade ages based on morphological data. We used four methods (cal3, extended Hedman, smoothed ghost lineage analysis (sGLA) and the fossilized birth–death model (FBD)) to date clade ages derived from a published crocodylomorph supertree and a new neosuchian phylogeny. All time‐scaling methods applied here agree on the origination of Neosuchia during the Late Triassic or Early Jurassic, and the presence of the major extant eusuchian groups (Crocodyloidea, Gavialoidea, Alligatoroidea and Caimaininae) by the end of the Late Cretaceous. The number of distinct lineages present before the K/Pg boundary is less certain, with support for two competing scenarios in which Crocodylinae, Tomistominae and Diplocynodontinae either: (1) diverged from other eusuchian lineages before the K/Pg boundary; or (2) evolved during a ‘burst’ of diversification after the K/Pg event. Cal3 and FBD proved to be the most suitable methods for time‐scaling phylogenetic trees dominated by fossil taxa. Extended Hedman estimates are substantially older than the others, with larger standard deviations and a strong sensitivity to taxon sampling and topological changes; sGLA has similar problems. We conclude that a detailed understanding of phylogenetic relationships, tree reconstruction methods, and good taxonomic coverage (in particular the inclusion of the oldest taxon in each clade) is essential when evaluating the results of such dating analyses.
Geolingüística del futuro evidencial en las lenguas romances a principios del siglo xx

El futuro morfológico en las lenguas romances puede expresar tiempo, modalidad y evidencialidad. La bibliografía afirma que casi todas las variedades emplean dicho tiempo para denotar inferencia o conjetura, pero los datos que manejan se basan en la propia introspección, así como en textos literarios. En este artículo, pretendemos dar cuenta de la vigencia del futuro morfológico a nivel dialectal en todas las lenguas romances de principios del siglo xx con el fin de determinar si, efectivamente, su valor conjetural ya era posible entonces y hasta qué punto se puede establecer que los romances poseen evidencialidad morfológica.
Clinical Outcomes of an Innovative Cefazolin Delivery Program for MSSA Infections in OPAT

Cefazolin is a recommended treatment for methicillin-susceptible Staphylococcus aureus (MSSA) infections that has been successfully used in outpatient parenteral antibiotic therapy (OPAT) programs. The aim of this study was to assess the clinical outcomes of cefazolin delivered each day (Group 24) vs. every two days (Group 48) for MSSA infections in OPAT programs. It was a prospective observational study with retrospective analysis of a cohort of MSSA infections attended in OPAT. The primary outcome was treatment success, defined as completing the antimicrobial regimen without death, treatment discontinuation, or readmission during treatment and follow-up. A univariate and multivariate logistic regression model was built. A two-sided p < 0.05 was considered statistically significant. Of the 149 MSSA infections treated with cefazolin 2 g/8 h in OPATs, 94 and 55 patients were included in the delivery Group 24 and Group 48, respectively. Treatment failure and unplanned readmission rates were similar in both groups (11.7% vs. 7.3% p = 0.752 and 8.5% vs. 5.5% p = 0.491). There was a significant increase in vascular access complications in Group 24 (33.0%) with respect to Group 48 (7.3%) (p < 0.001). Treating uncomplicated MSSA infection with cefazolin home-delivered every two days through an OPAT program is not associated with an increased risk of treatment failure and entails a significant reduction in resource consumption compared to daily delivery.
A Review of Mixed Lubrication Modelling and Simulation

Majority of the rolling contacts applied in complex interacting machine elements for example bearings and gears perform under Mixed Lubricating (ML) conditions, where the lubricant film can’t fully separate the asperities of the two contacting surfaces. Highly loaded, interacting asperity surrounded with lubricant film, leads to the development of surface originated defects such as scuffing, micropitting, and wear in the ML region. This region exists amid Elastohydrodynamic Lubrication and Boundary Lubrication which needs consolidated knowledge of fluid film and direct contact of asperities, this makes the problem more difficult to solve numerically. Numerous authors have used the Reynolds equation or its modified versions to solve the lubrication problem numerically. However, still, some uncertainty is there to model mixed lubrication operating conditions, with traditional Reynold’s equation, because the assumptions commonly made in Elastohydrodynamic lubrication are not valid within the context of mixed lubrication regime. In this paper previously, used models for mixed lubrication have been examined, and various development in related fields are discussed. Therefore, this review will provide an integrated, synthesized overview of the topic and in turn will lead to benefits for wide-ranging academic, industrial and research communities. © 2022 Published by Faculty of Engineering * Corresponding author: Zulfiqar Ahmad Khan E-mail: zkhan@bournemouth.ac. uk Received: 14 September 2021 Revised: 18 October 2021 Accepted: 10 November 2021
Mitochondrial DNA Variation Contributes to the Aptitude for Dressage and Show Jumping Ability in the Holstein Horse Breed

Simple Summary In the Holstein horse breed, maternal lineages are considered to be of major importance for the breeding success and can be examined through analysis of the maternally inherited mitochondrial DNA (mtDNA). Since mitochondrial genes are involved in energy metabolism, variation might contribute to differences in performance characteristics, as has already been pointed out in humans and racehorses with respect to endurance. No corresponding studies have yet been conducted for the athletic performance of warmblood breeds and, thus, the aim of this study was to investigate the influence of mitochondrial variation on the performance of Holstein mares. The data set used for this study was composed of both sequenced and non-sequenced mares of 75 maternal lineages as a previous study revealed that Holstein mares within a maternal lineage had identical mtDNA haplotypes regarding their non-synonymous variants. Association analyses were performed using estimated breeding values (EBVs) based on information from sport and breeding events. We observed mitochondrial single nucleotide polymorphisms (SNPs) significantly associated with one or more of the examined EBVs and identified mitochondrial haplogroups with a particular aptitude for dressage or show jumping. Abstract Maternal lineages are considered an important factor in breeding. Mitochondrial DNA (mtDNA) is maternally inherited and plays an important role in energy metabolism. It has already been associated with energy consumption and performances, e.g., stamina in humans and racehorses. For now, corresponding studies are lacking for sport performance of warmblood breeds. MtDNA sequences were available for 271 Holstein mares from 75 maternal lineages. As all mares within a lineage showed identical haplotypes regarding the non-synonymous variants, we expanded our data set by also including non-sequenced mares and assigning them to the lineage-specific haplotype. This sample consisting of 6334 to 16,447 mares was used to perform mitochondrial association analyses using breeding values (EBVs) estimated on behalf of the Fédération Équestre Nationale (FN) and on behalf of the Holstein Breeding Association (HOL). The association analyses revealed 20 mitochondrial SNPs (mtSNPs) significantly associated with FN-EBVs and partly overlapping 20 mtSNPs associated with HOL-EBVs. The results indicated that mtDNA contributes to performance differences between maternal lineages. Certain mitochondrial haplogroups were associated with special talents for dressage or show jumping. The findings encourage to set up innovative genetic evaluation models that also consider information on maternal lineages.
Sustainability of rural water supply schemes in Oke-Ogun of Oyo State, Nigeria

The study evaluates sustainability of rural water supply schemes in Oke-Ogun area of Oyo State, Nigeria. The objectives of the study covers examination of socio-economic characteristics of residents, identification of different types of water supply schemes, assessment of water supply schemes, evaluation of sustainability of water schemes, and factors affecting water scheme in the study area. Data were generated through random administration of questionnaires among 1,193 residents. It was further analyzed using descriptive method and sustainability index. The study further revealed problems of finance, bad community leadership, lack of cooperation, frequent change in government, high cost of materials and equipment, and poor participation of people in the planning and implementation of water facilities. It was recommended that in order to achieve sustainability of rural water supply projects, there is need to ensure effective organization, planning and implementation strategies through the active participation of rural community members. The study further recommends the partnership approach in addition to community approach in the planning and management of rural water supply facility in the study area.
Exploring the Effect of Parental Styles on Social Skills: The Mediating Role of Affects

Parental educational styles have a significant effect in personal development. These styles (authoritative, democratic, permissive and neglectful) can be related to affects and social skills at the individual level. The study presented here, which comprised 456 participants (151 men; 33.11%), with an average age of 22.01 years (s.d. = 2.80), aimed to analyse the relationship between parental styles, affects and social skills, as well as the role played by affects in the relationship between parental style and social skills. The results suggest that the constructs under study are closely related. The most common parental style is democratic. By gender, permissive styles were more often applied to women and authoritative styles to men. No significant gender differences were found in the application of democratic and neglectful parental styles. In terms of emotional support, women were found to have higher negative affect scores and men higher emotional support scores. People with parents that use democratic and permissive styles scored higher in all variables related to affects and social skills, which challenges the notion that democratic styles are the best parental styles in terms of socialisation of children. The results of the affect and social skills scales were analysed in relation to parenting styles, indicating that children educated under a democratic parental regime tend to yield higher scores in terms of social skills than children educated under any other form of parental regime and medium scores in terms of affects. Finally, it was found that parenting styles have a direct influence on social skills, which tend to improve when affects play a mediating role between these two constructs. These results suggest that parenting styles are closely related to affects and social skills. In addition, they also suggest that affects play a mediating role in the relationship between parenting styles and social skills. Finally, owing to the impact that parenting styles have on affects and social skills, more research is needed to address this issue.
The Peritoneal Membrane—A Potential Mediator of Fibrosis and Inflammation among Heart Failure Patients on Peritoneal Dialysis

Peritoneal dialysis is a feasible, cost-effective, home-based treatment of renal replacement therapy, based on the dialytic properties of the peritoneal membrane. As compared with hemodialysis, peritoneal dialysis is cheaper, survival rate is similar, residual kidney function is better preserved, fluid and solutes are removed more gradually and continuously leading to minimal impact on hemodynamics, and risks related to a vascular access are avoided. Those features of peritoneal dialysis are useful to treat refractory congestive heart failure patients with fluid overload. It was shown that in such patients, peritoneal dialysis improves functional status and quality of life, reduces hospitalization rate, and may decrease mortality rate. High levels of serum proinflammatory cytokines and fibrosis markers, among other factors, play an important part in congestive heart failure pathogenesis and progression. We demonstrated that those levels decreased following peritoneal dialysis treatment in refractory congestive heart failure patients. The exact mechanism of beneficial effect of peritoneal dialysis in refractory congestive heart failure is currently unknown. Maintenance of fluid balance, leading to resetting of neurohumoral activation towards a more physiological condition, reduced remodeling due to the decrease in mechanical pressure on the heart, decreased inflammatory cytokine levels and oxidative stress, and a potential impact on uremic toxins could play a role in this regard. In this paper, we describe the unique characteristics of the peritoneal membrane, principals of peritoneal dialysis and its role in heart failure patients.
Selected vs. Non-Selected Under-20 National Futsal Players: Differences between Physical Performance and Training Intensity Experienced in Training Camps

Simple Summary In sports training, the physical profiles and performances between selected and non-selected players are not identical. The players’ specific characteristics, such as exercise performance, locomotion profiles, and physical exertions during training sessions, can be used to identify the successful achievement in sports. However, such information has not been revealed in futsal. This study followed a prospective cohort design between 2018 and 2019. In our study, under-20 male Taiwan national futsal players were assessed for their physical fitness in two separate time periods. The perceived responses of physical exertion, exercise heart rate responses, and locomotion profiles were recorded during each training camp. Quantitative data during eighteen training camps/competition periods were collected for comparison. Our findings demonstrated that the selected players had a superior performance in 15 m Sprint and 30 m Sprint, exercise HR responses, and locomotor demands compared to the non-selected players. Coaches and their staff could consider the information of the present study for identifying selected players. Abstract The aim of this study was two-fold: (i) analyze the variations in the physical fitness of selected and non-selected under-20 male national futsal players; and (ii) analyze the variations in training intensity monitored during training camps. Thirty-three Taiwan under-20 national futsal players were monitored for training intensity during 18 training camps. They were divided into two groups: selected (n = 14) and non-selected (n = 17) players. The physical assessments included the following measures: body mass, distance covered at Yo-Yo intermittent recovery test Level 1, final velocity at 30-15 Intermittent Fitness Test (30-15 IFT), standing long jump, maximum heart rate (HR), and 1-min sit-up. The training intensity was monitored using the rate of perceived exertion (RPE), HR at different intensity zones, and locomotor demands measured at different speed thresholds. The results revealed that the selected players were significantly faster in the 15-m sprint with ball (p = 0.001) and 30-m sprint (p = 0.001). Additionally, the selected players presented significantly greater HRaverage and time spent above 90% maximum HR during the three-to-six-day training camps (p < 0.05) compared to the non-selected players. Interestingly, the NS demonstrated a greater number of sprints during the training camps (p = 0.001), while the selected players presented greater distance/minute and average speed (p = 0.001). A regression analysis showed that the distance/minute and average speed was a significant predictor of maximum HR in the selected players. As conclusions, the physical fitness outcomes are different between the selected and non-selected national futsal players. The selected players spent more time in high intensity HR demands in training sessions.
O-Band Frequency-Tunable (10–22 GHz) Ultra-Low Timing-Jitter (<12-fs) Regenerative Mode-Locked Laser

A frequency-tunable and low-timing-jitter O-band regenerative mode-locked laser (RMLL) using an optoelectronic oscillation configuration and electric-controlled yttrium iron garnet (YIG) bandpass filter is proposed and demonstrated. In this scheme, an O-band semiconductor optical amplifier (SOA) is used as the gain medium of the RMLL to realize a dispersion-management-free operation during frequency tuning. With a polarization-maintaining fiber loop of 300 m, we produced a robust frequency-tunable RMLL with a pulse width below 16 ps, phase noises below −123 dBc/Hz at a 10-kHz frequency offset from the carrier frequency, and timing jitter less than 12 fs (integrated in 1-kHz to 1-MHz range) in a frequency tuning range between 10 GHz and 22 GHz.
Characteristics of White Matter Integrity During Different Phases of Abstinence in Heroin Use Disorders: A Diffusion Tensor Imaging Study

Objectives The recovery of heroin-induced white matter impairment during abstinence has been reported, determining the characteristics of this recovery can help to improve the therapeutic strategies. In this study, we explored white matter characteristics in heroin use disorders during different phases of abstinence by using a quantitative diffusion tensor imaging method. Methods Seventeen and 22 male patients with long- and short-term abstinence (LA and SA, respectively) from heroin use and 20 male healthy controls participated in this study. Voxel-wise diffusion tensor imaging method was used for the comparison of fractional anisotropy (FA). Radial diffusivity (RD) and axial diffusivity (AD) were induced to explore the pathological characteristics of FA. The correlation between diffusion tensor indices and duration of abstinence was further analyzed. Results Compared to the healthy controls, patients with SA had significantly reduced FA in extensive white matter regions, while those with LA had only 2 clusters that showed reduced FA, which were located mainly in the genu of the corpus callosum, forceps minor, uncinate fasciculus, left inferior fronto-occipital fasciculus, superior longitudinal fasciculus, and posterior thalamic radiation. Significantly increased RD with unchanged axial diffusivity were detected. FA in the regions with the significant intergroup difference between SA and LA correlated positively with the duration of abstinence. The RD in these regions correlated negatively with the duration of abstinence. Conclusions The findings suggested that the time-dependent recovery of white matter, especially the restoration of the myelin sheath, occurred in patients with LA. Longer-abstinent duration with strategies of enhancing myelination may improve treatment effectiveness.
