Increasing Voltage Support Using Smart Power Converter Based Energy Storage System and Load Control

Voltage sag and swell affect the normal operation of loads as well as distributed generating sources and reduce the overall reliability of the system. For improving the voltage at point of common coupling, different grid code requires control of active and reactive powers through power electronic solutions. In this article, a smart power converter (SPC) is introduced in the distribution grid, and different from the existing voltage support solutions, this article utilizes control and coordination capabilities of SPC to provide medium voltage (MV) grid voltage support during voltage sag/swell. The proposed control scheme aims to improve the voltage support capability of SPC in the MV grid by the coordinated operation of SPC MV converter, low voltage converter, and battery energy storage system (BESS). For achieving the same voltage support capability, the proposed method requires lower rated BESS as compared to existing solutions. Simulation and experimental results show the effectiveness of the proposed scheme.
Chemical Composition of the Essential Oils from Stem, Root, Fruit and Leaf of Piper longum Linn

Abstract The essential oil obtained from the fresh parts of root, stem, fruit, and leaf of Piper longum growing wild in Western Ghats, Kerala was analyzed by GC-MS. The study led to the identification and quantification of 38 (root), 36 (stem), 29 (fruit) and 37 (leaf) chemical constituents belonging to different classes of compounds accounting for 96.9 %, 97.2 %, 97.1 % and 76.7 % of the total oil composition respectively. The essential oil production, yield of total volatile oil content in fruit and leaf was higher than that of root and stem. The principal components in root, stem, and fruit were comparable. The oil composition of root (62.0 %), fruit (71.5 %), and stem (69.2 %) was dominated by the presence of monoterpene hydrocarbons while the leaf had sesquiterpene hydrocarbons (68.7 %) as the major components. The high amount of monoterpene, especially pinene and camphene in the root, stem and fruit due to the freshness of the sample.
Psychosocial Distress among Adolescent Street Children in Tigray, Ethiopia: A Community-Based, Mixed-Method Study

Background: Street adolescent are the most marginalized group of population with a high risk of mental health and prolong exposure to psychosocial distress results in developing a compromised quality of life, healthy socialization, and overall development. Despite this fact, little attention is given to the psychosocial wellbeing of street children in Africa practically in Ethiopia. This study aimed to assess the psychosocial distress among street adolescents in Tigray, Ethiopia. Research Methodology: Community-based mixed cross-sectional study was conducted among 422 participants, and 4 focused group discussants. Study participants were selected conveniently in the quantitative part and purposively in the qualitative part. A pre-tested, semi-structured, interviewer-administered, and focused group discussion guide questionnaire was used to collect the data. Result: About 223 (55.1%) street adolescents were psychosocially distressed. Bing in the age range of 16-18 years old [(AOR=3.9, 95% CI: (1.6, 9.11)], meal availability once per day [(AOR=4.46, 95% CI: (1.83, 10.85)], being sexually abused [(AOR=2.36, 95% CI: (1.1, 4.95)], meal availability twice per day [(AOR=4.24, 95% CI: (1.91, 9.44)], being physically abused [AOR= 2.43, 95% CI: (1.05, 5.63)], and low income status (parents) [(AOR=2.6, 95% CI: (1.59, 4.24)] were significantly associated factors. Conclusion: More than half of the participants have psychosocially distressed. Establishing and implementing local mental health policies and programs for street children through collaborative efforts with the government and nongovernment sectors to bring them into the mainstream of the society. Family reintegration and strengthen the legal systems to minimize violence are also important measures to decrease the problem.
Parenting from Prison: Perceptions of Incarcerated Parents' Ability and Influence

OF THESIS PARENTING FROM PRISON: PERCEPTIONS OF INCARCERATED PARENTS’ ABILITY AND INFLUENCE Incarcerated parents are at a substantially higher risk for losing their legal right to parent than the general public. This study assessed implicit perceptions and biases that may play a role in these legal decisions, specifically the perceptions of incarcerated parents’ ability to parent and influence their children’s lives. Court appointed special advocate (CASA) volunteers’ (N = 242) perceptions of incarcerated parents based on the parents’ personal characteristics, characteristics of their children, and characteristics of their criminal activity were assessed through a true-experiment design. Ordinal regression analyses revealed that age of child, level of violence in the crime committed, and criminal history are all relevant factors in assessing parental ability and influence. Additionally, patterns were found in respondents’ open-ended responses suggesting that racial and gender bias may also play a role, despite the statistical nonsignificance of close-ended responses. Implications and future directions are discussed.

Strategies of Native Culture Integration in College English Teaching Based on “Education of Chinese Ethics and Culture in All Courses”

Language is one of the carriers of culture. Language teaching cannot be divorced from cultural teaching. As an important compulsory course of general education in university, college English has long largely ignored the teaching of native language nature, which affects students’ cultural consciousness and confidence. The aphasia of Chinese culture in inter-cultural communication has caused wide concerns and worries in the field of foreign language teaching. Based on the concept of education of Chinese ethics and culture in all courses, the first part of this paper introduces the basic idea of education of Chinese ethics and culture in college English teaching and the problem of aphasia of English expression for Chinese cultures which leads to the lack of cultural consciousness and confidence. Then in the second part, the paper deeply discusses and explores the reasons for Chinese culture aphasia in college English teaching from the perspectives of teaching syllabus, teachers and students, textbooks and teaching materials and assessment systems. The third part of the paper puts forward a series of efficient strategies from the aspects of teaching and learning ideas, teaching mode, curriculum setting and evaluation mechanism. Finally, conclusions and reflections that need further consideration and research are discussed in the fourth part of this paper.

The availability of internet access has created a rapid change in learning. This paper aims to investigate the impact of effort expectancy and facilitating conditions on behavioral intention to use mobile learning for Taibah University students in Saudi Arabia by using the unified theory of acceptance and use of technology model. Quantitative research methodology is used, so that the research-proposed formulated hypothesis will be tested. A sample of 110 Taibah University students was drawn. A survey questionnaire was designed for data collections to measure the impact of effort expectancy and facilitating conditions on behavioral intention to use mobile learning for Taibah University students. The independent variables of the research model are effort expectancy and facilitating conditions. The dependent variable is behavioral intention to use. The data was analyzed using statistical techniques, including reliability, validity, and regression analysis. The results indicate that effort expectancy and facilitating conditions were significant and directly influenced students' behavioral intention to use mobile learning.
The Role of Fatigue in the Aging Swallow: A Review

Fatigue is a term commonly used to describe patient performance and/or subjective experience in the evaluation and management of swallowing disorders (known as dysphagia). There is an association between fatigue and aging, as well as fatigue and many dysphagia-causing diseases/disorders. Therefore, speech-language pathologists (SLPs) are justifiably aware of and concerned about the potential impact of fatigue on swallowing performance and mealtime behavior. However, there is minimal agreement on and understanding of what constitutes swallowing-related fatigue, how it is identified and measured, who is at risk, and its impact on swallowing function, overall health, and quality of life. The purpose of this review is to discuss the role of fatigue in swallowing and eating behavior in the context of aging, and how fatigue may be measured and managed clinically. We review the concept of fatigue and its clinical implications for swallowing function and mealtime behavior through the dichotomous framework of self-perceived fatigue versus measurable fatigability. Quantitative fatigability and patient-reported fatigue are discussed. We conclude with implications for future research.
Does Service Provider Matter during a Pandemic? COVID-19 Cases and Deaths among Nonprofit vs. For-Profit Assisted Living Facilities in Florida

When COVID-19 hit the U.S. in early 2020, individuals aged 65+ were identified as a higher risk population. In Florida, Governor DeSantis issued Emergency Order 20-006 to prohibit visitation to facilities housing groups of high-risk people, including assisted living facilities (ALFs). Regardless, 672 ALFs of the 3,019 in Florida had reported at least one positive case of COVID-19 by a resident or staff member as of June 30, 2020. Prior research has highlighted the differences in service delivery between nonprofit and for-profit health care providers. This manuscript fills the void of minimal research on quality of care differences among ALFs based on ownership status. We find that nonprofit ALFs have experienced fewer positive cases of COVID-19 among their residents, but less evidence of a difference between nonprofit and for-profit ALFs in terms of resident deaths. We also find evidence that the type of nursing services matters for protecting ALF residents from COVID-19.
In-Bundle Surgeons More Likely Select Cemented Femoral Fixation in Total Hip Arthroplasty for At-Risk Patients

Background: Bundled payment models for lower-extremity arthroplasty have been shown to lower costs but have not reliably improved quality. It is unknown how the bundled payment model may affect surgeons’ decisions that impact the quality of arthroplasty care. The purpose of this study was to compare the utilization of femoral component fixation modes by surgeons performing total hip arthroplasties (THAs) in at-risk patients in areas subject to Medicare’s Comprehensive Care for Joint Replacement (CJR) bundled payment model compared with patients treated by surgeons in areas exempt from the policy. Methods: Elective, primary THAs among elderly persons were identified from Medicare claims during 2017 and 2018, including the use of cemented or cementless femoral fixation. Multivariable regression models, applied to samples stratified by sex, were used to assess the association between CJR bundle participation and the use of femoral fixation mode. Analyses were adjusted for patient age, race or ethnicity, comorbidity burden, low-income status, and Census division of the hospital. Results: Of 118,676 Medicare patients who underwent THA, 9.1% received cemented femoral components, and use of cement varied significantly by geographic region (p < 0.001). Patients who received cemented fixation, compared with patients who received cementless fixation, had significant differences in mean age (and standard deviation) at 78.3 ± 6.9 years compared with 74.5 ± 6.1 years (p < 0.001) for female patients and 77.3 ± 6.8 years and 74.2 ± 5.9 years (p < 0.001) for male patients; were more likely to be White at 94.0% compared with 92.7% (p < 0.001) for female patients and 95.1% compared with 93.8% (p = 0.046) for male patients; and had higher mean Elixhauser comorbidity index at 2.6 ± 2.2 compared with 2.3 ± 2.0 (p < 0.001) for female patients and 2.8 ± 2.4 compared with 2.4 ± 2.1 (p < 0.001) for male patients. In adjusted analyses, female patients in the CJR bundled payment model were more likely to have cemented fixation compared with female patients not in the CJR model (odds ratio [OR], 1.11 [95% confidence interval (CI), 1.05 to 1.16]; p < 0.001), whereas male patients in the CJR bundled payment model were less likely to have cemented fixation compared with male patients not in the CJR model (OR, 0.91 [95% CI, 0.83 to 0.99]; p = 0.029). Conclusions: In the bundled environment, surgeons were more likely to choose cemented femoral fixation for elderly female patients. This may be due to in-bundle surgeons being more risk-averse and avoiding cementless fixation in patients at risk for fracture or implant-related complications. Further research is needed to directly examine the impact of the bundle on surgeon decision-making.

Context-Based Multiscale Unified Network for Missing Data Reconstruction in Remote Sensing Images

Missing data reconstruction is a classical yet challenging problem in remote sensing images. Most current methods based on traditional convolutional neural network require supplementary data and can only handle one specific task. To address these limitations, we propose a novel generative adversarial network-based missing data reconstruction method in this letter, which is capable of various reconstruction tasks given only single source data as input. Two auxiliary patch-based discriminators are deployed to impose additional constraints on the local and global regions, respectively. In order to better fit the nature of remote sensing images, we introduce special convolutions and attention mechanism in a two-stage generator, thereby benefiting the tradeoff between accuracy and efficiency. Combining with perceptual and multiscale adversarial losses, the proposed model can produce coherent structure with better details. Qualitative and quantitative experiments demonstrate the uncompromising performance of the proposed model against multisource methods in generating visually plausible reconstruction results. Moreover, further exploration shows a promising way for the proposed model to utilize spatio-spectral-temporal information. The codes and models are available at https://github.com/Oliiveralien/Inpainting-on-RSI.
Development of a wheelchair propulsion laboratory

The measurement of handrim wheelchair propulsion characteristics and performance in the field is complicated due to the non-stationary nature of wheelchair driving. In contrast, the laboratory provides a constrained and standardisable environment to conduct measurements and experiments. Apart from wheelchair treadmills, dynamometers or ergometers for handrim wheelchairs are often custom-made, one-of-a-kind, expensive, and sparsely documented in the research literature. To facilitate standardised and comparable lab-based measurements in research, as well as in clinical settings and adapted sports, a new wheelchair ergometer was developed. The ergometer with instrumented dual rollers allows for the performance analysis of individuals in their personal handrim wheelchair and facilitates capacity assessment, training and skill acquisition in rehabilitation or adapted sports. The ergometer contains two servomotors, one for each rear wheel roller, that allow for the simulation of translational inertia and resistive forces as encountered during wheelchair propulsion based on force input and a simple mechanical model of wheelchair propulsion. A load cell configuration for left and right roller enables the measurement of effective user-generated torque and force on the handrim and the concomitant timing patterns. Preliminary results are discussed.
