Concept analysis of a distributed thrust system, a novel inductive propulsion method using high energy pulse solenoids in satellite swarms for reusable interorbital freight transport
Authors: Wegener Morgan J.
Published: November 2022

To date only single vehicle thrust designs have been considered for propulsion in space, however there is no limitation preventing multivehicle distributed thrust application designs if a rigid structure can be constructed electromagnetically. By considering the regularity of planetary orbits and distance between orbital paths, a location in space can be targeted for next orbit arrival of a shipping container propelled on an intercepting vector that is a result of inductive propulsion vector combination. This concept is achieved with Nb3Sn high energy pulse solenoids that enable a square pyramidal swarm of satellites to decompose the intercepting orbital transfer vector and propel a 20 tonne steel shipping container towards a destination swarm. This paper is a thought experiment with first pass mechanical analysis that establishes a validity algorithm then concludes that the proposed yoked solenoid design is fit for purpose. Two factors are noted as key variances that must be investigated in further research with numerical modelling tools before the proposed design can be considered fully functional.

Published: November 2022

Objectives: Indicators of oral and periodontal diseases have previously been associated with handgrip strength and muscle mass and function in older adults in several populations. However, research in middle-aged adults on the relationship between periodontitis and handgrip strength and skeletal muscle mass – another important indicator of sarcopenia – has been limited. This study investigated the association between periodontitis and sarcopenia indicators in middle-aged adults from a U.S. population.
Materials and Methods: Adults with complete periodontal and whole-body dual x-ray absorptiometry examinations from the 2013–2014 wave of the National Health and Nutrition Examination Survey (NHANES) were analysed using fully adjusted multiple linear regression models for associations between periodontitis diagnosis and severity and skeletal muscle mass index (SMMI) and combined handgrip strength (cHGS).
Results: A subset of 1,912 individuals with a complete periodontal examination and whole-body dual x-ray absorptiometry scan from the NHANES 2013–2014 main cohort (n = 10,683) were included in the analysis. The median age of the participants was 43 years. Overall, 32% of the participants (n = 612) were determined to have periodontitis. Of these, 513 (26.8%) had non-severe (mild or moderate) periodontitis, and 99 (5.2%) had severe periodontitis. Both non-severe and severe periodontitis showed significant associations with cHGS (ß = -2.28, 95% CI -3.57–-0.98 and ß = -2.84, 95% CI -5.37–-0.31, respectively), but not with SMMI.
Conclusion: The findings of the current study indicate that periodontitis and handgrip strength are interrelated. The present study highlights the need of further prospective research to investigate the nature and direction of the relationship between periodontitis and sarcopenia indicators.
Clinical relevance: Future studies can support the screening, prevention and clinical management of sarcopenia and periodontitis, and emphasize the interdisciplinary and complementary approach between the disciplines of geriatric medicine and periodontology.

Published: November 2022

Background: The detection of SARS-CoV-2 vRNA in clinical samples has relied almost exclusively on RT-qPCR as the gold standard test. Published results from various external quality assessments (“ring trials”) worldwide have shown that there is still a large variability in results reported for the same samples. As reference standards of SARS-CoV-2 RNA are available, we tested whether using standard curves to convert Ct values into copies/mL (cp/mL) improved harmonization.
Methods: Nine laboratories using 23 test systems (15 of which were unique) prepared standard dilution curves to convert Ct values of 13 SARS-CoV-2 positive samples to cp/mL (hereafter IU/mL). The samples were provided in three rounds of a virus genome detection external quality assessment (EQA) scheme. We tested the precision and accuracy of results reported in IU/mL, and attempted to identify the sources of variability.
Results: Reporting results as IU/mL improved the precision of the estimated concentrations of all samples compared to reporting Ct values, although some inaccuracy remained. Variance analysis showed that nearly all variability in data was explained by individual test systems within individual laboratories. When controlling for this effect, there was no significant difference between all other factors tested (test systems, EQA rounds, sample material).
Conclusions: Converting results to copies/mL improved precision across laboratory test systems. However, it seems the results are still very specific to test systems within laboratories. Further efforts could be made to improve accuracy and achieve full harmonization across diagnostic laboratories.

Finite Element Analysis-Based Evaluation of the Patient-Specific Spinal Rods for a Reduced Risk of Adjacent Segment Disease
Authors: ŞENSOY Abdullah Tahir
Published: November 2022

Adjacent Segment Disease (ASD) is a postoperative drawback of spinal fusion surgery which yields an increase in the range of motion in the adjacent spinal level. Therefore, the main aim of this study is to investigate the optimum mechanical properties of the spinal rod allowing a reduced rigidity in the spinal fixation level for decreasing the displacement of the adjacent segment. In this study, the spinal fixation system was modelled and attached to L3-L4 level. The elasticity modulus of the rods and the follower load were parametrically defined in order to investigate their optimum values under physiological loading conditions of extension. The maximum displacement value determined for the upper adjacent intervertebral disc was defined as the output parameter. Thereafter, the biomechanical response of the spinal bone-implant complex was simulated using Finite Element Analysis (FEA). Using the parametric FEA results, a polynomial mathematical model was constructed and Response Surface Method (RSM) was used to plot the relationship between input and output parameters. According to the results of the study, the optimum elasticity modulus of the rods and the suggested follower load have been determined as 80.8 GPa and 303.84 N, respectively. The maximum principal strain values obtained in the pedicle screws were 746 µℇ, 1563 µℇ, 3037 µℇ and 2937 µℇ, respectively. However, since the results are strongly associated with anatomical and biomechanical differences, the proposed patient-specific approach may enhance the accuracy for a more successful spinal fusion surgery operation in terms of minimizing the risk of ASD.
CO2 emissions and their changes with H2O emissions, soil moisture, and temperature during the wetting–drying process of the soil mixed with different biochar materials
Authors: Yerli Caner , Cakmakci Talip , Sahin Ustun
Published: November 2022

Biochar is an organic regulator that improves crop yield by regulating soil properties. In addition, this organic regulator is also effective in reducing CO2 emissions from soil. However, considering the management of CO2 emissions together with many factors and the different properties of soil depending on the biochar content, CO2 emissions can vary. Thus, the study investigated the soil moisture and temperature and H2O emissions, which affect the emission, and CO2 emission of biochars with different raw materials applied to the soil in the wetting–drying cycle of the soil. It was determined that biochar applications decreased CO2 emissions, but the share of each biochar material in reduction differed, and CO2 emissions were 82, 51, 20, and 13% lower in straw, hazelnut, apple, and sawdust biochar applications than in soil without biochar, respectively, and significant positive linear relationships of CO2 emissions with soil moisture–temperature and H2O emissions were determined. In addition, in biochar applications, H2O and soil temperature decreased depending on the moisture retention in the soil. In the findings, it can be suggested that straw biochar application to soil is more effective in reducing the severity of increasing global warming, and that soil moisture and temperature should be managed to reduce CO2 emissions.

Published: November 2022

Numerical study was conducted by using ABAQUS software to investigate two issues on spun pile connections. The issues are usage of non-shrinkage concrete infill cast inside hollow of pile and ductility. An experimental test was carried out to investigate the effect of two different concrete infill types which were common concrete fc’ 35 MPa and non-shrinkage concrete fc’ 54 MPa. A finite element model was validated against experimental test. The results were compared in terms of hysteresis curve, ductility, and performance level. Ductility is one of the important parameters to describe performance of spun pile connections under seismic load. There are different approaches to calculate ductility and this leads to four different ductility values. Hence, ductility of spun pile with concrete infill is in the range of 3.2 to 4.8. Behavior of spun pile with non-shrinkage concrete infill is slightly improved although the results were almost similar.

IT and the Quality and Efficiency of Mental Health Care in a Time of COVID-19: Case Study of Mental Health Providers in England
Authors: Konteh Frederick Hassan , Mannion Russell , Jacobs Rowena
Published: November 2022

Background

In England, COVID-19 has significantly affected mental health care and tested the resilience of health care providers. In many areas, the increased use of IT has enabled traditional modes of service delivery to be supported or even replaced by remote forms of provision.

Objective

This study aimed to assess the use and impact of IT, in remote service provision, on the quality and efficiency of mental health care during the pandemic. We drew on sociotechnical systems theory as a conceptual framework to help structure the gathering, analysis, and interpretation of data.

Methods

We conducted a national scoping survey that involved documentary analysis and semistructured interviews with 6 national stakeholders and case studies of 4 purposefully selected mental health providers in England involving interviews with 53 staff members.

Results

Following the outbreak of COVID-19, mental health providers rapidly adjusted their traditional forms of service delivery, switching to digital and telephone consultations for most services. The informants provided nuanced perspectives on the impact on the quality and efficiency of remote service delivery during the pandemic. Notably, it has allowed providers to attend to as many patients as possible in the face of COVID-19 restrictions, to the convenience of both patients and staff. Among its negative effects are concerns about the unsuitability of remote consultation for some people with mental health conditions and the potential to widen the digital divide and exacerbate existing inequalities. Sociotechnical systems theory was found to be a suitable framework for understanding the range of systemic and sociotechnical factors that influence the use of technology in mental health care delivery in times of crisis and normalcy.

Conclusions

Although the use of IT has boosted mental health care delivery during the pandemic, it has had mixed effects on quality and efficiency. In general, patients have benefited from the convenience of remote consultation when face-to-face contact was impossible. In contrast, patient choice was often compromised, and patient experience and outcomes might have been affected for some people with mental health conditions for which remote consultation is less suitable. However, the full impact of IT on the quality and efficiency of mental health care provision along with the systemic and sociotechnical determinants requires more sustained and longitudinal research.

Authors: Matava Clyde , So Jeannette P , Hossain Alomgir , Kelley Simon
Published: November 2022

Background

During the quiescent periods of the COVID-19 pandemic in 2020, we implemented a weekend-scheduled pediatric surgery program to reduce COVID-19–related backlogs. Over 100 staff members from anesthesiologists to nurses, surgeons, and administrative and supporting personnel signed up to work extra weekends as part of a novel weekend elective pediatric surgery program to reduce COVID-19–related backlog: Operating Room Ramp-Up After COVID-19 Lockdown Ends-Extra Lists (ORRACLE-Xtra).

Objective

In this study, we sought to evaluate staff perceptions and their level of satisfaction and experiences with working extra scheduled weekend elective surgical cases at the end of the 3-month pilot phase of ORRACLE-Xtra and identify key factors for participation.

Methods

Following the pilot of ORRACLE-Xtra, all perioperative staff who worked at least 1 weekend list were invited to complete an online survey that was developed and tested prior to distribution. The survey collected information on the impact of working weekends on well-being, overall satisfaction, and likelihood of and preferences for working future weekend lists. Logistic regression was used to estimate the association of well-being with satisfaction and willingness to work future weekend lists.

Results

A total of 82 out of 118 eligible staff responded to the survey for a response rate of 69%. Staff worked a median of 2 weekend lists (IQR 1-9). Of 82 staff members, 65 (79%) were satisfied or very satisfied with working the extra weekend elective lists, with surgeons and surgical trainees reporting the highest levels of satisfaction. Most respondents (72/82, 88%) would continue working weekend lists. A sense of accomplishment was associated with satisfaction with working on the weekend (odds ratio [OR] 19.97, 95% CI 1.79-222.63; P=.02) and willingness to participate in future weekend lists (OR 17.74, 95% CI 1.50-200.70; P=.02). Many (56/82, 68%) were willing to work weekend lists that included longer, more complex cases, which was associated with a sense of community (OR 0.12, 95% CI 0.02-0.63; P=.01).

Conclusions

Staff participating in the first 3 months of the ORRACLE-Xtra program reported satisfaction with working weekends and a willingness to continue with the program, including doing longer, more complex cases. Institutions planning on implementing COVID-19 surgical backlog work may benefit from gathering key information from their staff.

Air pollution particularly that of particulate matter (PM 2.5, PM 2.10), carbon monoxide, ozone, nitrogen dioxide, sulfur dioxide, ammonia, lead, and air microbial contaminants, has serious consequences on human health. Air pollution in metros and cities around the world is measured for the above parameters except for the microbial air contaminants. However, microbial air contaminants are important sources of microbial infection in humans and particularly airborne fungi are known to cause diseases like Aspergillosis and Mucormycosis in immunocompromised patients which are about 160 million in the world.In the year 2021, Mucormycosis disease was reported as a post-covid infection in several states of India as a fatal disease caused by a black fungus (Mucor) prevalent in the atmospheric air. In the present study, we assessed the microbial air quality (colony forming unit of microbes/m3 of air) of Nashik city air, in India, for its microbial contaminant, particularly Mucor sp., and further the prevalent Mucor sp. was evaluated for its reaction to two triazole antifungal drugs viz. Itraconazole and Fluconazole available in medical stores.The air quality index of 90 CFU/tidal volume for Mucor species was regarded as safe, based on the studies. Both the triazole drugs at their active ingredient concentration (1000 µg/mL) were unable to check the growth of Mucor fungi. The paper discussed in detail the methods for enumeration of microbial contaminant/m3 of air and in tidal volume.

Deep Learning Based Model to Forecast the Direction of Stock Exchange Market Using social media: A Review
Authors: Shah Miss. Prajakta Pradeepkumar , S. S. Prof. Gujar
Published: November 2022

Abstract: A company's stock exchange price is not just a measure of the present worth of the value of its shares, but an indicator of its expected future performance as well. The company is an incorporated organization with the Regulatory Body and shares trading members are registered with SEBI. Given that stock market statistics are extremely time-specific and usually nonlinear in nature, it is very difficult to forecast future stock values. The forecast offers details about the present state of the flow of inventory values. This will also be used to decide whether to purchase or sell the individual shares of the particular stock for consumers. Many scientists were conducted with different data mining techniques to forecast stock market prices. This paper attempts to forecast the stock price of companies in the national stock exchange index LIX15 using Neural Network technology. For designing and training the models, the past data of the chosen stock will be used. To verify the consistency of the model, the effects of the model are used for comparison with actual data.
A Systematic Review and Taxonomy on Electrical Load Forecasting for Optimizing Power Generation
Authors: Bhagel Ravi , Goad Shalini
Published: November 2022

Abstract: There happens to be a continuous mismatch between the amount of generation and the load required for power systems. The necessity for matching of lad is necessary as lesser load than generation may lead to standing waves on the transmission line and power feedback paths. While the excessive load may put enormous amount of pressure on the generating end with limited generation capability. Hence, it is necessary to match the demand and load conditions for any power system. This inevitable needs accurate forecasting models for electrical load so as to make estimates regarding the future load conditions of any system. While electrical load forecasting a time series forecasting model, the dependence on the multitude of parameters makes the load forecasting a challenging problem. This paper presents a review on the current techniques for electrical load forecasting based on statistical regression problems so as to enhance the balance among the electrical load required and the generation.

Education is crucial in changing human behaviour toward environmental management. The Walisongo Eco-Green Campus (WeGreen) is a program that aims to achieve Sustainable Development Goals, so it is necessary to prepare the students of Biology teacher candidates to have good environmental literacy. This study aims to describe the environmental literacy of the students of Biology teacher candidates based on the academic year. The sampling technique used in this study was stratified random sampling. The sample of the study was 339 students of Biology teacher candidates in four different academic years. Data collection techniques used are tests and questionnaires. The data obtained from the measurement result of environmental literacy were analyzed descriptively using the mean and standard deviation formulas. The results of the Kruskal-Wallis test show a significance value of 0.451 (p>0.05) on the cognitive aspect and 0.535 (p>0.05) on the affective aspects. In addition, the result on behavioural aspects is 0.012 (p<0.05). There is no difference in environmental literacy (cognitive aspects and affective aspects) of the students of Biology teacher candidates based on the academic year, but there is a difference in students’ behaviour aspects. Students with the most different behaviour are those in the academic year of 2019 (fifth semester).

El objetivo de esta investigación fue describir los ajustes razonables que se implementan para la inclusión laboral de personas en situación de discapacidad en el contexto empresarial ibaguereño y su incidencia en la prevención de riesgos laborales. Este se desarrolló desde un enfoque mixto bajo un diseño explicativo secuencial de selección de participantes en el cual se vincularon veintitrés empleados y cinco empleadores de empresas locales. Los instrumentos aplicados hacen referencia, en primer lugar, a la encuesta de caracterización, la cual se implementó en la fase cuantitativa que tuvo como propósito la selección de participantes, y en segundo lugar, a la entrevista abierta semiestructurada como instrumento y técnica utilizada en la fase cualitativa y sobre la cual se sustentan los resultados del proceso realizado que aquí se describe, desde el abordaje de dos categorías generales de estudio: los ajustes razonables y la prevención inclusiva. Los principales hallazgos mostraron que, con relación a los ajustes razonables, en la mayoría de los casos obedecen a adaptaciones que ha realizado el trabajador para desenvolverse de manera adecuada en su puesto y solo en las empresas grandes se encuentran modificaciones y/o adaptaciones realizadas por los empleadores, en coherencia con la legislación nacional definida para tal fin. Con relación a la prevención inclusiva, existe una percepción distal entre empleador y empleado, en donde el primero centra su interés en los aspectos físicos de los riesgos, y el segundo en los aspectos sociales del entorno laboral, siendo las barreras actitudinales y comunicacionales los principales factores de riesgo en el contexto del trabajo.

This study compares the turmoil that occurred in the trade sector and the Indonesian tourism sector before and during the COVID-19 outbreak. The research method used is quantitative with a comparative approach. The data used is secondary data sourced from the Ministry of Trade of the Republic of Indonesia and the Ministry of Tourism of the Creative Economy of the Republic of Indonesia. This study uses a statistical test tool in the form of SPSS Version 21 with Paired Sample T-Test. The results showed significant differences in the trade sector before the onset of covid-19 and during the occurrence of covid-19. This occurred from the spread of Covid-19, which caused supply and demand shocks. The decline in trade reflects rising trade costs, disruptions to transportation, logistics, supply chains, and trade restrictions. Furthermore, there are significant differences in the tourism sector before the onset of covid-19 and during covid-19. This happened due to travel restrictions imposed by the government, causing a reduction in both domestic and international travel. The spread of the COVID-19 pandemic has caused foreign tourists to cancel trips and book tickets on a large scale, and the reluctance of tourists to visit is influenced by concerns about the impact of tourism travel during the pandemic.

Xenon postconditioning attenuates neuronal injury after spinal cord ischemia/reperfusion injury by targeting endoplasmic reticulum stress-associated apoptosis
Authors: Luo Lan , Wang Yu , Tong Jia , Li Lu , Zhu Yan , Jin Mu
Published: November 2022

Mechanistic studies have demonstrated that apoptosis is key to the
pathogenesis of spinal cord ischemia/reperfusion injury (SCIRI), and
that endoplasmic reticulum (ER) stress-associated apoptosis contributes
to SCIRI. Importantly, strong evidence has shown that xenon (Xe) has
neuroprotective effects. This study investigated whether Xe
postconditioning had beneficial effects on SCIRI by inhibiting ER
stress-associated neuronal apoptosis. A spinal cord I/R rat model was
induced by abdominal artery occlusion for 85 min and reperfusion.
Subsequently, Xe postconditioning (50% Xe) was administered 1 h after 1
h of reperfusion. We showed that after SCIRI, rats displayed obvious
serious spinal cord damage after reperfusion for 4 h, morphological
changes, and neuronal damage associated with ER stress-induced
apoptosis. However, spinal cord damage above was attenuated in response
to Xe treatment. Furthermore, administration of the ER stress inhibitor
sodium 4-phenylbutyrate strongly decreased ER stress-induced apoptosis
following SCIRI. This study highlights that Xe postconditioning inhibits
ER stress activation, which contributes to alleviate SCIRI by
suppressing neuronal apoptosis.

Pomegranate peel contains bioactive ingredients such as flavonoids, ellagitannins, phenolics and proanthocyanidin compounds with high antioxidant activity. Pomegranate peel has antiapoptotic, antioxidant and anti-inflammatory effects due to its high punicalagin content. We aimed to determine the effect of pomegranate peel extract (PPE) on lipopolysaccharide (LPS)-induced uveitis. Sixty rats were seperated randomly into twelve groups (n = 5). The healthy group received intraperitoneal normal saline, the uveitis group received 200 μg/kg LPS, the dexamethasone (DEX) group received 200 μg/kg LPS plus 1 mg/kg DEX, the PPE100, PPE300 and PPE500 groups received 200 μg/kg LPS plus 100, 300 and 500 mg/kg PPE, respectively. The eye tissues were collected at 3rd and 24th hour. and investigated molecularly (Relative quantification of gene expression), biochemically (Superoxide dismutase activity, Glutathione and Malondialdehyde levels) and histopathologically (staining with Harris Hematoxylin and Eosin Y). Tumor Necrosis Factor-α, vascular endothelial growth factor, and Caspase-3 levels markedly decreased in a dose-dependent manner in the uveitic rats following PPE administration. PPE administration significantly ameliorated uveitic disorders in oxidative stress factors including Glutathione, Superoxide dismutase and Malondialdehyde, with its effects raising in a dose-dependent manner. PPE eliminated histopathological changes in eye tissues due to uveitis. PPE can be a promising agent by contributing to alternative preventive treatment methods for uveitis with its anti-inflammatory, antioxidative, antiapoptotic and antiangiogenic effects.

Published: November 2022

The regular practice of physical exercise is a factor of health promotion and injury prevention, but, despite this unquestionable truth, people are becoming physically inactive with age. The creation of physical activity habits at younger ages, at school, for example, based on adequate, sensible, and motivating exercise prescriptions, can promote long lasting physical exercise. This text reviews this theme, emphasizing the intensity of counseling for sports practice.

Sequências de Ensino Investigativas (SEI) estimulam a observação, o levantamento de hipóteses e a resolução de problemas. Este trabalho teve como objetivo construir e validar uma SEI sobre o conteúdo Tecido Conjuntivo Hematopoiético no ensino médio de uma escola pública. Construímos nossa metodologia a partir das seguintes etapas: problematização; leitura e construção de glossário; elaboração de casos clínicos; criação de hipóteses e discussão. Observamos que 80% dos estudantes demonstraram desconhecimento sobre hemograma e nenhum sabia interpretá-lo. Um glossário foi construído com 21 termos, ressignificando os conceitos. Os estudantes conseguiram descrever os diagnósticos criados pelos colegas sobre anemia, desidratação, processo infeccioso viral, processo alérgico e risco de hemorragia. A avaliação revelou que a atividade foi considerada satisfatória e o nível de complexidade foi acessível. Observamos que cada momento contribuiu na interpretação de textos, no reconhecimento de dificuldades terminológicas e na construção de hipóteses.
