Very high cycle fatigue under tension/torsion loading of mold low alloy steel
Authors: Costa Pedro R. da , Reis Luis , Freitas Manuel
Published: May 2022

Ultrasonic fatigue testing is a recent fatigue methodology that applies
resonant principles to induce cyclic stresses in a modally designed
specimen enabling the application of fatigue damage at very high
frequencies. Its primary purpose is to study fatigue life in the Very
High Cycle Fatigue regime between 10E07 and 10E09 cycles with a higher
performance of time and energy wise compared to conventional
servo-hydraulic fatigue testing machines. In this study, an ultrasonic
fatigue testing machine was used to carry out multiaxial tension/torsion
fatigue tests at a frequency of 20 kHz. The objective was to reach a
reliable multiaxial fatigue testing method by modifying only the
specimen, with the ability to induce different shear to axial stress
ratios. The improved design/methodology of the testing ultrasonic
multiaxial method focused first on the innovative design specimens and
setup modal behaviour by conducting both numerical and experimental
analyses. Laser displacement measurements, thermographic imaging, and
rosette strain gauges applied to the specimen’s fatigue stress region
were carried out to validate the new design concept and compared with
the computed results obtained by finite element. A good numerical to
experimental results agreement was achieved. A series of fatigue tests
were carried out in tension/torsion fatigue to three different combining
dimension specimens allowing three different shear/axial stress ratios.
The resulting crack initiation angles and fracture surfaces were
analysed and compared not only between each other but also with
tension-compression and pure torsion ultrasonic tested specimens.

Published: May 2022

The influence of load ratio on the high and very high cycle fatigue
(VHCF) strength of Ck45M steel processed by thermomechanical rolling
integrated direct quenching was investigated. Ultrasonic fatigue tests
were performed under uniaxial and torsional loading at load ratios of
R = −1, 0.05, 0.3 and 0.5 with smooth specimens and specimens
containing artificially introduced defects. Up to 2×10
 cycles, failure originated from surface aluminate
inclusions and pits under both loading conditions. The prevailing
fracture mechanisms in the VHCF regime were interior crack initiation
under uniaxial loading and surface shear crack initiation under
torsional loading. The mean-stress sensitivity and the fatigue strength
were evaluated using fracture mechanics approaches. Equal fatigue limits
for uniaxial and torsional loading were determined considering the size
of crack initiating defects and the appropriate threshold condition for
Mode-I crack growth. Furthermore, the mean-stress sensitivity is
independent of loading condition and can be expressed by σ w R = σ w R =
- 1 ∙ 1 - R 2 0.63 and τ w R = τ w R = - 1 ∙ 1 - R 2 0.63 .
SNF472: Progress towards a novel therapeutic agent for vascular calcification and calciphylaxis
Authors: Yang Canlin , Wei Zhiyuan , Ji Jie , Zhang Xiaoliang
Published: May 2022

Vascular calcification (VC) is a common complication in chronic kidney
disease (CKD) patients and is strongly associated with the increased
risk of cardiovascular diseases and all-cause mortality. Calciphylaxis
is a rare type of VC with extremely high mortality, characterized by
intense pain and skin damage secondary to systemic arteriolar
calcification, and is most common in patients with CKD. Currently, the
treatment of VC and calciphylaxis in CKD focuses on controlling risk
factors and has made very little progress. SNF472 is a novel VC
inhibitor that has demonstrated outstanding efficacy and safety in
recent clinical trials. This review highlights the current knowledge and
progress of the latest clinical research on SNF472.

Authors: Lai Lingyun , Zhang Yingshi , Li Xiang , Zhang Yan , Zhang Meiling , zhao qingchun
Published: May 2022

Abstract Aims: The aim of this study was to synthesize the evidence on
the effects of SGLT2i on multiple outcomes in the treatment of heart
failure and to analyze the effects of different SGLT2i and heart failure
on outcomes. Methods: We searched Pubmed, MEDLINE, Embase, and Web of
Science. Randomized placebo-controlled parallel trials evaluating the
efficacy of SGLT2i on the treatment of heart failure and reporting one
of all-cause death, cardiovascular outcome, health status, cardiac
function, laboratory indicators, and the safe outcomes were included,
whose follow-up time were more than one month. Results: Our
meta-analysis demonstrated that SGLT2i reduced the risk of
cardiovascular mortality and hospitalization for heart failure. Also,
SGLT2i increased KCCS-CSS and KCCS-TSS score. Furthermore, SGLT2i
reduced patients’ LVEDVI, body weight and systolic blood pressure.
Additionally, SGLT2i protected against the risk of severe adverse
events, acute kidney injury, but was more likely to cause hypotension,
urinary tract infection and genital infection. Unfortunately, SGLT2i
raised creatinine levels in patients. We could observe similar trends in
results from outcomes where subgroup analysis by different SGLT2i and
heart failure. Conclusion: SGLT2i contributed to better cardiovascular
and survival outcomes. SGLT2i also improved health status, heart
function and metabolism to some extent. In addition, SGLT2i was
generally safe, but with higher risk of urinary tract infections,
genital infections, hypotension and creatinine levels. Keywords: SGLT2i

Hospital Pharmacists' opinions on a risk prediction tool for medication-related harm in older people
Authors: Hussain Ahmed , Ali Khalid , Davies Graham , Stevenson Jennifer , Lippett Samantha , O'Malley Mairead , Parekh Nikesh , Rajkumar Chakravarthi
Published: May 2022

Aim: Older adults are particularly affected by medication-related harm
(MRH) during transitions of care. There are no clinical tools predicting
those at highest risk of MRH post-hospital discharge. The PRIME study
(prospective study to develop a model to stratify the risk of MRH in
hospitalized patients) developed and internally validated a
risk-prediction tool (RPT) that provides a percentage score of MRH in
adults over 65 in the eight-weeks following hospital discharge. This
qualitative study aimed to explore the views of hospital pharmacists
around enablers and barriers to clinical implementation of the
PRIME-RPT. Methods: Ten hospital pharmacists: (band 6 (n=3); band 7
(n=2); band 8 (n=5)) participated in semi-structured interviews at the
Royal Sussex County Hospital (Brighton, UK). The pharmacists were
presented with five case-vignettes each with a calculated PRIME-RPT
score to help guide discussion. Case-vignettes were designed to be
representative of common clinical encounters. Data were thematically
analysed using a ‘framework’ approach. Results: Seven themes emerged in
relation to the PRIME-RPT: 1. providing a medicine-prioritisation aide;
2. acting as a deprescribing alert; 3. facilitating a holistic review of
patient’s medication management; 4. simplifying communication of MRH to
patients and the multidisciplinary team; 5. streamlining community
follow-up and integration of risk discussion into clinical practice; 6.
identifying barriers for the RPTs integration in clinical practice and
7. acknowledging its limitations. Conclusion: Hospital pharmacists found
the PRIME-RPT beneficial in identifying older patients at high-risk of
MRH following hospital discharge, facilitating prioritising
interventions to those at highest risk while still acknowledging its
limitations.
Composite Gaussian Pulsed Waveform For Robust Resonance Radar Signature
Authors: Aldhubaib Faisal
Published: May 2022

The paper assesses the feasibility of forming a composite excitation
pulse with a high potential to combat the noise and onset ambiguity when
estimating the target resonance behaviour in a radar target signal. The
assessment investigates four composite pulse configurations of unified
or adaptive setups for the fractional bandwidth and peak weight to find
the best setup in enhancing the resonance signature robustness. The
assessment uses the method pencil function to extract the resonance
parameters of the composite time data (coherent) and then determine the
degree of robustness over-extraction onset and range of noise level.
Determining the robustness rate requires finding the error between the
original excitation frequencies and the extractable resonant frequencies
and, second, the similarity between the original and reconstructed pulse
waveforms. The qualitative assessments of the robustness merit concluded
that the adaptive configuration of peak weight and small adaptive
fractional bandwidth outperforms the other configurations in enhancing
the resonance signature robustness.

Identification of Novel Disease-Relevant Genes and Pathways in the Pathogenesis of Type 1 Diabetes: A Potential Defect in Pancreatic Iron Homeostasis
Authors: Yip Linda , Alkhataybeh Reem , Taylor Cariel , Fuhlbrigge Rebecca , Fathman C. Garrison
Published: May 2022

Multiple pathways contribute to the pathophysiological development of type 1 diabetes (T1D); however, the exact mechanisms involved are unclear. We performed differential gene expression analysis in pancreatic islets of NOD mice versus age-matched congenic NOD.B10 controls to identify genes that may contribute to disease pathogenesis. Novel genes related to extracellular matrix development and glucagon and insulin signaling/secretion were changed in NOD mice during early inflammation. During “respective” insulitis, the expression of genes encoding multiple chemosensory olfactory receptors were upregulated, and during “destructive” insulitis, the expression of genes involved in antimicrobial defense and iron homeostasis were downregulated. Islet inflammation reduced the expression of Hamp that encodes hepcidin. Hepcidin is expressed in β-cells and serves as the key regulator of iron homeostasis. We showed that Hamp and hepcidin levels were lower, while iron levels were higher in the pancreas of 12-week-old NOD versus NOD.B10 mice, suggesting that a loss of iron homeostasis may occur in the islets during the onset of “destructive” insulitis. Interestingly, we showed that the severity of NOD disease correlates with dietary iron intake. NOD mice maintained on low-iron diets had a lower incidence of hyperglycemia, while those maintained on high-iron diets had an earlier onset and higher incidence of disease, suggesting that high iron exposure combined with a loss of pancreatic iron homeostasis may exacerbate NOD disease. This mechanism may explain the link seen between high iron exposure and the increased risk for T1D in humans.

C-peptide declines in type 1 diabetes, although many long-duration patients retain low, but detectable levels. Histological analyses confirm that β-cells can remain following type 1 diabetes onset. We explored the trends observed in C-peptide decline in the UK Genetic Resource Investigating Diabetes (UK GRID) cohort (N = 4,079), with β-cell loss in pancreas donors from the network for Pancreatic Organ donors with Diabetes (nPOD) biobank and the Exeter Archival Diabetes Biobank (EADB) (combined N = 235), stratified by recently reported age at diagnosis endotypes (<7, 7–12, ≥13 years) across increasing diabetes durations. The proportion of individuals with detectable C-peptide declined beyond the first year after diagnosis, but this was most marked in the youngest age group (<1-year duration: age <7 years: 18 of 20 [90%], 7–12 years: 107 of 110 [97%], ≥13 years: 58 of 61 [95%] vs. 1–5 years postdiagnosis: <7 years: 172 of 522 [33%], 7–12 years: 604 of 995 [61%], ≥13 years: 225 of 289 [78%]). A similar profile was observed in β-cell loss, with those diagnosed at younger ages experiencing more rapid loss of islets containing insulin-positive (insulin+) β-cells <1 year postdiagnosis: age <7 years: 23 of 26 (88%), 7–12 years: 32 of 33 (97%), ≥13 years: 22 of 25 (88%) vs. 1–5 years postdiagnosis: <7 years: 1 of 12 (8.3%), 7–12 years: 7 of 13 (54%), ≥13 years: 7 of 8 (88%). These data should be considered in the planning and interpretation of intervention trials designed to promote β-cell retention and function.
The Time Has Come: Journal of Endodontic Microsurgery: A First Peer-Reviewed Open Access Publication Focused on Microsurgery in Endodontics
Authors: Fesenko Ievgen
Published: May 2022

Multiple articles, textbooks and chapters, parts of the residency programs, meetings` topics, courses with hands-on training, and social media groups with more than 12,600 members; it`s not a full list of the scientific and practical developments associated with endodontic microsurgery (EM). The field of endodontics and EM is flourishing around the globe and more and more dental clinics/offices became equipped by microscopes, special EM instruments, used 3-D printed cutting guides, and educate their stuff, etc.
Analysis of the existed publications at the (1) Portal of International Standard Serial Number (ISSN) International Center and (2) SCImago Journal and Country Rank [10] revealed a scholar gap in such growing field as EM. Using a search function at the Portal of ISSN International Center, all publications with a word endodontic(s), endodontology, microsurgery, and microsurgical in their titles were analyzed and no endodontic microsurgery was found.
Among 141 journals of in a subject area “Dentistry,” category “Dentistry (Miscellaneous),” (metrics based on Scopus® data as of April 2021) only eight of them (5.67%) have the word endodontic(s) in their titles (Table 1). Moreover, as of September 30, 2021 another endodontic publication (Endodontology journal) became a Scopus-indexed journal. Thus, despite nine endodontically-focused journals are included to the prestigious database and published some number of EM papers; none of them are focused precisely on EM. That is why an initiative group of five EM-associated practitioners take a responsibility as chief editors to move the EM direction forward with a new Journal of Endodontic Microsurgery (JEM). The names of those experts and opinion leaders are Spyros Floratos (Greece, United States), Daniel Flynn (United Kingdom), Carlos Aznar Portoles (Netherlands), Oleksandr B. Tkachenko (Ukraine) (Fig 1), and Puala Villa (Colombia). All editors have a clear purpose to publish every year a volume of high-quality peer-reviewed articles.
Relation between Neutrophil-Lymphocyte Ratio and Inflammatory Markers in Assessing the Severity of COVID-19 Disease
Authors: AVK Manasathreya , M Rama Devi
Published: May 2022

Background: The identification of effective laboratory biomarkers together with the clinical presentation is crucial to categorize the severity of the disease. The following biomarkers have been identified: Neutrophil-lymphocyte ratio (NLR), Inflammatory C-reactive protein (CRP), Serum Ferritin levels, Serum Lactate Dehydrogenase. Cytokine storm is one of the most dreaded complications of COVID19 that can be treated effectively by early identification. The current study is to test and confirm the prognostic value of NLR as an economic and reliable indicator of COVID19.

Methodology: The current study is a retrospective observational study. The data of COVID-19 patients admitted to a tertiary care hospital from the 25th of August, 2021 to the 25th of September, 2021 was analyzed. Patients were categorized into mild, moderate, and severe groups based on ICMR guidelines. The blood reports from the day one of admission were taken into consideration for this study.

Results: The study included 71 patients consisting of 29 males and 42 females, with a male to female ratio of 0.69. In the present study, 52 patients are with mild disease (Males-19; Females-33), 12 (males-4; females-8) are in the moderate category, and 7 (males-1; females-6) patients have severe disease. In mild patients, the mean CRP was 4.01mg/L, the mean serum Ferritin was 214.23mcg/L, and the mean NLR was 3.62. In patients with moderate severity, the mean CRP was 5.86mg/L, the mean serum Ferritin was 383.62mcg/L, and the mean NLR was 5.67. In patients with severe disease, the mean CRP was 22.71mg/L, the mean serum Ferritin was 805mcg/L, and the mean NLR was 15.3.

Conclusion: The study showed that there is a gradual increase in CRP, Serum Ferritin, and NLR with the increase in severity of disease from mild to severe. NLR is gradually increasing with increasing mean CRP and serum Ferritin levels Hence, NLR can be used as a reliable predictor of the severity of the disease instead of CRP and serum Ferritin in places lacking adequate facilities.

Published: May 2022

Hairdresser’s salons are public places that can contribute to the spread of viral, fungi and bacterial pathogens. However, little is known about the contamination of hairdressing tools by bacterial and fungal pathogens. Hence, this study was conducted to determine bacterial and fungal contaminants of tools used in hairdressing salons within Wukari metropolis, Taraba State. Eighty (80) different samples were collected from combs, brushes, rollers, and hairdryers used in hairdressing salons using sterile swab stick moistened with normal saline. Samples were cultured aerobically on nutrient agar, MacConkey agar, and sheep blood agar for bacterial isolation and potato dextrose agar for fungal isolation. Bacterial isolates were identified using conventional biochemical tests while fungal isolates were identified on the basis of their cell wall structure using the lactophenol cotton blue stain. Antibiotic sensitivity pattern of bacterial isolates was tested using the modified Kirby-Bauer disc diffusion method. Sixty-seven (83.75%) of the collected sample were positive for bacterial and/or fungal contamination, yielding twenty-two (22) and eighteen (18) isolates each of bacteria and fungi. The bacterial isolates were Staphylococcus aureus (81.82%), Staphylococcus epidermidis (13.64%), and Escherichia coli (4.64%) while the fungal isolates were Aspergillus fumigatus (31.25%), Aspergillus flavus (50%), Aspergillus niger (6.25%), Madurella grisea (6.25%), and Rhizopus stolonifera (6.25%). Bacterial isolates were generally sensitive to ciprofloxacin, gentamicin, rifampicin, ofloxacin, and streptomycin. The highest resistances were against cefuroxime, trimethoprim-sulfamethoxazole, ampicillin, and augmentin. The presence of these microorganisms on hairdressing tools is an indication of poor hygienic practices among hairstylists in Wukari and these tools can serve as vehicles for the transmission of bacterial pathogens. Hence, appropriate measures should be taken to reduce the microbial load from hairdressing salons instruments.

Methodology: The study was conducted after approval from the ethical review committee of the Foundation University College of Dentistry, Islamabad from June 2021 to September 2021. Inclusion criteria adhered to the recruitment of fourth and final-year students of dentistry. Informed written consent was taken after explaining the study protocol. The format of the questionnaire was based on previously published studies, literature, and guidelines provided by Centers for Disease Control. The questionnaire was validated by a Pilot Study and the opinion of dental health experts on the subject. Methodology constituted of a paper-based and web-based questionnaire with closed-ended questions and feedback were received from (60%) participants. Variables for analysis included demographic profile, next section comprised of questions regarding COVID – 19 disease knowledge, its precautionary measures, and attitude towards the disease. Moreover, participant's awareness in case of suspected infection was also analyzed to gauge the level of preparedness. There was a total of 256 participants enrolled in this study via consecutive non-probability sampling methodology.

Results: There was a total of 256 participants enrolled in this study. Out of 256, 154 (60.2%) were male and 102 (39.8%) were females. 110(42.8%) believed that COVID-19 symptoms resolve without treatment, 256(100%) believed that disease spread can be prevented with education. 222(86.6%) endorsed a preference to avoid or work with the COVID-19 Patient. As per opinion regarding social distancing, wearing masks and washing hands before initiation of treatment, 246(95.1%) believed it to be mandatory for disease transmission reduction whereas 38(14.9%) considered it unnecessary.

Conclusion: Dental students demonstrated ample awareness and knowledge regarding COVID-19 disease presentation, preventive measures, and strategy in case of suspected infection with a motivated attitude to spread awareness among the population.

Authors: Schwela Dietrich H. , Wilke Martin , Perschon Jürgen , Hertel Christof , Scherp Philipp
Published: May 2022

The aim of this paper is to estimate the reduction of CO2e emissions due to pedelecs partially replacing motorized vehicles in Uganda in five steps: (A) Pedelec and lithium-ion battery production; (B) Transport from the manufacturer in India to its destination in Uganda. (C) CO2e reduction due to pedelec use partially substituting motorized vehicles - passenger cars, boda-bodas and matatus. (D) The appropriate part of motorised vehicle emissions that should be credited to pedelecs partially replacing transport by these vehicles, increasing pedelec CO2e reduction. The last step (E) is to combine all these individual estimates to a conservative estimate of the net reduction of CO2e emissions due to pedelecs in Uganda. Two modal distributions are assumed for the partial replacement of motorised vehicles by pedelecs. Depending on the modal split the net CO2e reduction per year of one pedelec ranges between approximately 2.5 and 2.9 tonnes CO2e.

Published: May 2022

Student Research and Innovation Program (SRIP) is one of the major training programmes and is broadly used to promote students’ ability of scientific research. However, the exact impact of a planned strategy of early SRIP on the research productivity of medical students remains unknown. Here we conducted a complete and reliable questionnaire survey to investigate the situation of early SRIP in improving the research interests and the academic index was used to evaluate the research productivity in medical students. The results showed that more than half of medical students at Ningbo University School of Medicine participated in SRIPs in junior grades. Personal interest was a major motive and selective criteria for SRIP. Meanwhile, SRIP was found to be self-managed and well arranged in medical students. Interestingly, early scientific research training benefited students in both academic and non-academic achievements. The statistical analysis showed that the freshman participants yielded the most productive academic achievements. Additionally, the planned SRIP is considered useful, challengeable, and supportive for medical students. These findings reveal the potential value of the wider implementation of early SRIP throughout the school years in enhancing the research ability of medical students.
Possibilities of Using By-Products and Residues of Avocado Tree for Energy Generation in Chania, Crete, Greece
Authors: Vourdoubas John
Published: May 2022

The use of renewable energies, including solid biomass, for energy generation is important in modern societies for coping with the current environmental challenges like climate change. The avocado-related biomass in Chania, Crete, Greece has been evaluated and its energy potential has been estimated. The reason of implementing the present study was the investigation of the possibilities of using the by-products and residues of the avocado tree in Chania for the production of valuable products and energy. Avocado’s fruit production in Crete is estimated at 6,300 tons annually while its by-products and residues have been evaluated at 550 dry tons annually. The avocado-related biomass in Chania is very low compared with the total biomass produced in Crete which is estimated in the range of 82,555 to 123,172 tons/year. Agriculture-related biomass in Crete is mainly produced from by-products and residues of olive trees, citrus trees, vineyard pruning and greenhouse wastes. The energy content of the avocado-related biomass in Crete has been estimated at 2.43 x 109Kcal/year which is very low compared with the heat content of the total biomass production in the island. It is concluded that due to the low quantity of avocado by-products and residues produced in Chania, Crete the best options for their utilization are either their use for heat generation in rural areas or their disposal into the fields enriching the soil with nutrients.
The Planck Mass Density Radius of the Universe
Authors: Haug Espen G. , Gianfranco Spavieri
Published: May 2022

What is the size of the universe if we take the estimated mass in the observable universe and compress it until we reach the Planck mass density? We will investigate this using both the Friedmann model and the recent Haug model of the universe that takes into account Lorentz relativistic mass. The resulting size is approximately that of a proton. We will also look at a hypothetical Planck mass size universe. In the Friedmann model one needs rapid expansion of mass to maintain the initial Planck mass density or, alternatively, only space expansion with the density decreasing from its initial conditions, while in the Haug model the Planck mass universe seems to cause no such “strange” predictions.
Evolving human resource management processes and interventions as the new paradigms shaped by entrepreneurship, knowledge management, social network analysis’
Authors:   Bucks New University, UK, Das Sarat Chandra
Published: May 2022

At the core of human resource management (HRM) is the way ‘’inter-relationship among the stakeholders in an organisation is managed’’, ‘’objective criteria are applied to goal-setting processes’’ and how ‘’HRM contributes to the creation of tangible value in the form of knowledge-based outputs.’’ Hence, the process of knowledge management of storing and sharing in regard to its processes, techniques and operations is linked to HRM practices of effective management of this inter-relationship. The research enquires into how human resource development focuses on building the entrepreneurial resilience, a key ability of entrepreneurs to overcome challenges and adapt to uncertainties, particularly during this era of Covid-19 pandemic. The efforts of organisational leadership, which needs to appropriate these inter-relationships to a social context either India or Bangladesh, always can be aided by a host of social network theories. Within remit of this discourse, the research would like to pursue the questions such as how the role of gender in the economic development process has been increasingly recognized as crucial, both in terms of potential for success and in the nature of the impact of particular development strategies and programs. Addressing these questions, thus, can help us to arrive at the possible HR interventions in this regard. The direction of the current research emerges from the interpretation of the variants such as knowledge workers, knowledge management templates and tools, expected gender roles of social actors, resource allocation, etc. The research proceeds to enquire how these variants are explained by these social network theories, their limitations and if some of these need to be repurposed in the view of emerging challenges posed by knowledge workers and their belonging industries.
É possível erradicar o analfabetismo absoluto no brasil até 2024?
Authors: Alves Oliveira Bolivar
Published: May 2022

Um dos objetivos da Meta 9 do atual Plano Nacional de Educação (PNE 2014-2024) é a erradicação do analfabetismo absoluto até 2024. Em 2021, havia no Brasil quase 9,9 milhões de pessoas de 15 anos ou mais que não sabiam ler e escrever. É possível, até 2024, alfabetizar todo esse contingente de analfabetos? Neste artigo, argumenta-se, com base nas séries históricas dos quantitativos de analfabetos, de 2012 a 2021, em nível Brasil, regiões, unidades federativas e por grupos etários (adolescentes de 15 a 18 anos; jovens de 19 a 29 anos; adultos de 30 a 59 anos; e idosos de 60 anos ou mais), bem como nos números de adolescentes, jovens, adultos e idosos analfabetos fora e dentro da escola, em 2021, que o fenômeno do analfabetismo absoluto ainda persistirá em todas essas populações etárias. No plano formal, chega-se à mesma conclusão, ao serem analisadas as estratégias da Meta 9 do PNE 2014-2024 e as metas dos respectivos planos estaduais e distrital de educação, voltadas para a erradicação do analfabetismo absoluto nos estados e no Distrito Federal.

In the current study the hypothesis that 1.0% dietary inclusion of glutamine (Gln), a conditionally essential amino acid that influences protein synthesis and shows anti-osteoporotic effect, can influence eggshell quality was tested on laying hens in the post-peak laying period. Thirty-week-old Bovans Brown hens were randomly assigned to control group or group supplemented with Gln in the form of alphaketoglutarate (10 g/kg) with 12 replicate cages (2 hens/cage) in each group. The experimental period lasted for 30 weeks, from the 31st to the 60th week of age of hens, when eggs were collected and selected eggshell quality indices were determined. While Gln supplementation had no effect on egg geometry and eggshell cracking force, the analysis of eggshell quality showed an increase of the eggshell thickness (P<0.01), porosity (P<0.01), eggshell specific surface (P<0.001) and positive changes in other mechanical parameters (decrease of eggshell stiffness and Young’s modulus, P<0.05 and P<0.01, respectively; increase of work needed to crack the eggshell, P<0.05). Changes in eggshell mineral composition, including an increase of Ca content (P<0.001), were also observed. In conclusion, the current study showed a beneficial effect of Gln on the eggshell thickness, calcification, and some mechanical parameters.

The present study evaluated the effects of different carbohydrates materials used as carbon sources on water quality, biofloc quality, and growth and productive performance of Nile tilapia (Oreochromis niloticus) reared in biofloc (BFT)-based cement ponds (25 m x 10 m x 1.2 m; with 250 m3 volume). Nile tilapia fingerlings (44.9±1.9 g) were distributed into nine ponds at a density of 40 fish per 1 m3 (10000 fish/pond) to represent three treatments in triplicates. The control ponds received no carbon source addition; meanwhile sugarcane molasses (MO) and wheat flour (WF) were added to ponds. A commercial diet (30% crude protein) was offered to fish in each pond at levels of 3% and 2% of live body weight of fish in the control and BFT-based ponds, respectively, for 12 weeks. The amounts of feed were divided equally to three equal portions and offered to fish at 9:00, 13:00, and 17:00 h. The control ponds’ water was replaced by 50% every day with new water; meanwhile in MO and WF ponds, water loss via evaporation or leakage was compensated to reach the 1.0 m depth only. The pH value as well as unionized ammonia and nitrite levels, in the present study, were significantly lower, meanwhile nitrate and total suspended solids levels were significantly higher in MO and WF-treated ponds than the control one. The WF treatment resulted in significantly larger biofloc volume and higher total bacterial count compared to the MO treatment. The highest growth and production indices of Nile tilapia were observed in the BFT-based treatments as compared with the control group; particularly at the WF treatment followed by the MO treatment. In conclusion, the WF addition to cement fishponds is a more beneficial carbonaceous source for the efficient water quality, biofloc biomass, and growth and productivity of Nile tilapia reared in BFT-based system.

Published: May 2022

Introduction: The COVID-19 is a disease caused by the SARS-CoV-2 virus. A number of psychological symptoms have been identified in people living during the COVID-19 pandemic. Most of them are associated with widely understood anxiety disorders, which have always been a significant problem for mental health.

Materials and methods: The available literature was reviewed on the Pubmed platform and from other sources. The analysis included original studies, reviews, meta-analyzes and internet sources. The aim of the study was to review the literature on the relationship between the COVID-19 pandemic and the occurrence and severity of symptoms of anxiety disorders.

Results: The studies conducted so far show that the COVID-19 pandemic has had a significant impact on the mental state of people around the world, especially in the area of anxiety disorders. Many studies indicate an increase in the prevalence of symptoms of generalized anxiety disorder. Research also indicates a greater incidence of post-traumatic stress disorder and panic disorder in society. Symptoms of somatization were also quite often observed in patients. However, the state of published studies indicates that the pandemic did not significantly affect the severity of symptoms associated with social phobia. In the context of phobic disorders, a new type has been formulated: COVID-19-related phobia.

Conclusions: The conducted literature review shows that the current COVID-19 pandemic is associated with an increase in the prevalence of symptoms of anxiety disorders in the general population. The multifaceted nature of the issue of anxiety disorders in the COVID-19 pandemic clearly indicates the need to continue research in this area.
Negative Focus, Self-Doubt, and Issues of ‘Tool Proficiency’: Beginner-Coaches’ Reflections on Reflective Practice
Authors: Hamblin May , Crisp Philippe
Published: May 2022

In the field of sports coaching education and learning, reflective practice is considered central to transforming experience and knowledge into expertise, and many governing bodies execute this through professional development and specific guidelines (Vallance, 2019). However, whilst the general consensus within academia and the vocational sector of coaching continue to espouse this approach, there is a lack of evidence to suggest how this is useful for beginner-coaches (defined as emerging-new, with less than three years of experience) as studies generally focus on expert coaches and oftentimes sit within the context of performance and/or elite sport. This study, therefore, aimed to explore the benefits and limitations of reflective practice, and to identify aspects of ideal learning for in-situ, practice-based context as perceived by beginner-coaches who operate more within recreational (although still competitive) sport fields. Situated within the UK context, the methodology comprised of semi-structured interviews conducted with six beginner-coaches. The findings demonstrated that whilst there were tangible benefits to the use of reflective practice (such as perceived additional competency and critical thinking), there were also limitations centred on time constraints, and an over-focus on negative emotions with a subsequent adverse impact on self-confidence and anxiety. The implications, including recommendations and thoughts for the future, are outlined within the paper.
The Problematic Institutional Context of Greek Football and the Role of FIFA and UEFA
Authors: Pouliopoulos Theofilos , Georgiadis Konstantinos
Published: May 2022

Greek football is on the periphery of European football and it frequently faces scandals and corruption issues. Also, there appears to be a correlation between the wider social and political context and football. Additionally, FIFA and UEFA arguably have contributed to the fate of Greek football. For example, in the past when the Greek government tried to intervene in football, FIFA prevented them several times with the threat of a ban. During the previous years, FIFA and UEFA decided to cooperate with the Greek government and play a more active role in Greek football. However, little has changed in the governance of Greek football. This study has examined the context, critical incidents and the role of actors in Greek football. By using the Institutional Theory approach, our analysis indicates that the institutional context is highly problematic, as the big clubs dominate the institutional mechanisms of football. Corruption appears to be deeply embedded in the structures and operations of football, while the Hellenic Football Federation is controlled by the big clubs. In parallel, there is no plan for the overall development of football, from the grassroots to the elite level. The study concludes with a recommendation for the reformation of Greek football.
A Hybrid Energy Storage System with Reconfigurability and Fast Equalisation
Authors: Jiang Bowen , Liu Yujing
Published: May 2022

With the rapid growth of electric vehicles (EVs) in recent years, the research on their energy storage systems (ESSs) has also shown great popularity. A traditional ESS normally has a fixed configuration and uses a single type of energy storage unit. However, this traditional design has some limitations, such as low flexibility and high requirements to unit consistency. To solve these problems, a new hybrid energy storage system is proposed in this paper. The proposed ESS hybridises multiple lithium-ion battery modules and one supercapacitor module. By controlling the states of switches inside the ESS topology, module level reconfiguration can be achieved. Further, a DC/DC converter is also included in the ESS topology, which is connected to the supercapacitor module and can be used to ensure correct ESS output voltage. Reconfiguration and active balancing algorithms are also given based on the proposed ESS topology. Situations with and without bypassing the lithium-ion battery modules are both discussed in the algorithms. The proposed hybrid ESS is finally verified with simulations. The system model is built in the Simulink/MATLAB environment. Simulation results show that the lithium-ion modules with a lower state of charge values have higher priorities to be connected in parallel. Reconfiguration actions are able to balance all lithium-ion battery modules within one Worldwide Harmonised Light-Duty Vehicle Test Cycle (WLTC) simulation cycle while maintaining ESS output voltage within a correct range. Furthermore, the proposed hybrid ESS control algorithms remain valid when one lithium-ion battery module is manually bypassed during simulation.
