A robust model-free controller for a three-phase grid-connected photovoltaic system based on ultra-local model
Authors: Boubakir Ahsene , Touil Sid-Ahmed , Labiod Salim , Boudjerda Nasserdine 
Published: December 2021

AbstractIn this paper, a robust model-free controller for a grid-connected photovoltaic (PV) system is designed. The system consists of a PV generator connected to a three-phase grid by a DC/AC converter. The control objectives of the overall system are to extract maximum power from the PV source, to control reactive power exchange and to improve the quality of the current injected into the grid. The model-free control technique is based on the use of an ultra-local model instead of the dynamic model of the overall system. The local model is continuously updated based on a numerical differentiator using only the input–output behavior of the controlled system. The model-free controller consists of a classical feedback controller and a compensator for the effects of internal parameter changes and external disturbances. Simulation results illustrate the efficiency of the controller for grid-connected PV systems.
Maximum production point tracking method for a solar-boosted biogas energy generation system
Authors: Chen Jialin , Yang Ruijiang , Xu Da , Zhou Bin , Jin Yifang 
Published: December 2021

AbstractLow biogas yield in cold climates has brought great challenges in terms of the flexibility and resilience of biogas energy systems. This paper proposes a maximum production point tracking method for a solar-boosted biogas generation system to enhance the biogas production rate in extreme climates. In the proposed method, a multi-dimensional R–C thermal circuit model is formulated to analyze the digesting thermodynamic effect of the anaerobic digester with solar energy injection, while a hydrodynamic model is formulated to express the fluid dynamic interaction between the hot-water circulation flow and solar energy injection. This comprehensive dynamic model can provide an essential basis for controlling the solar energy for digester heating to optimize anaerobic fermentation and biogas production efficiency in extreme climates. A model predictive control method is developed to accurately track the maximum biogas production rate in varying ambient climate conditions. Comparative results demonstrate that the proposed methodology can effectively control the fermentation temperature and biogas yield in extreme climates, and confirm its capability to enhance the flexibility and resilience of the solar-boosted biogas generation system.
Considerations for conducting and reporting digitally supported cognitive interviews with children and adults
Authors: Fry Abigail , Mitchell Sandra A. , Wiener Lori 
Published: December 2021

Abstract
Background
Cognitive interviewing is a well-established qualitative method used to develop and refine PRO measures. A range of digital technologies including phone, web conferencing, and electronic survey platforms can be leveraged to support the conduct of cognitive interviewing in both children and adults. These technologies offer a potential solution to enrolling underrepresented populations, including those with rare conditions, functional limitations and geographic or socioeconomic barriers. In the aftermath of the COVID-19 pandemic, the use of digital technologies for qualitative interviewing will remain essential. However, there is limited guidance about adapting cognitive interviewing procedures to allow for remote data capture, especially with children.

Methods
Synthesizing the literature and our research experiences during the COVID-19 pandemic, we examine considerations for implementing digitally supported cognitive interviews with children, adolescents, and adults. We offer recommendations to optimize data quality and empirical rigor and illustrate the application of these recommendations in an ongoing cognitive interviewing study to develop and refine a new pediatric PRO measure.

Results
Good research practices must address participant and researcher preparation for study-related procedures and should anticipate and pre-emptively manage technological barriers. Field notes should detail interview context, audio/video cues, and any impact of technological difficulties on data quality. The approaches we recommend have been tested in an ongoing cognitive interviewing study that is enrolling children/adolescents with cGVHD ages 5–17 and their caregivers [NCT 04044365]. The combined use of telephone and videoconferencing to conduct cognitive interviews remotely is feasible and acceptable and yields meaningful data to improve the content validity of our new PRO measure of cGVHD symptom bother.

Conclusion
Digitally supported cognitive interviewing procedures will be increasingly employed. Remote data collection can accelerate accrual, particularly in multi-site studies, and may allow for interviewer personnel and data management to be centralized within a coordinating center, thus conserving resources. Research is needed to further test and refine techniques for remote cognitive interviewing, particularly in traditionally underrepresented populations, including children and non-English speakers. Expansion of international standards to address digitally supported remote qualitative data capture appears warranted.

Abstract
Background
Electronic health records (EHR) data can be used to understand population level quality of care especially when supplemented with patient reported data. However, survey non-response can result in biased population estimates. As a case study, we demonstrate that EHR and survey data can be combined to estimate primary care population prescription treatment status for migraine stratified by migraine disability, without and with adjustment for survey non-response bias. We selected disability as it is associated with survey participation and patterns of prescribing for migraine.

Methods
A stratified random sample of Sutter Health adult primary care (PC) patients completed a digital survey about headache, migraine, and migraine related disability. The survey data from respondents with migraine were combined with their EHR data to estimate the proportion who had prescription orders for acute or preventive migraine treatments. Separate proportions were also estimated for those with mild disability (denoted “mild migraine”) versus moderate to severe disability (denoted mod-severe migraine) without and with correction, using the inverse propensity weighting method, for non-response bias. We hypothesized that correction for non-response bias would result in smaller differences in proportions who had a treatment order by migraine disability status.

Results
The response rate among 28,268 patients was 8.2%. Among survey respondents, 37.2% had an acute treatment order and 16.8% had a preventive treatment order. The response bias corrected proportions were 26.2% and 11.6%, respectively, and these estimates did not differ from the total source population estimates (i.e., 26.4% for acute treatments, 12.0% for preventive treatments), validating the correction method. Acute treatment orders proportions were 32.3% for mild migraine versus 37.3% for mod-severe migraine and preventive treatment order proportions were 12.0% for mild migraine and 17.7% for mod-severe migraine. The response bias corrected proportions for acute treatments were 24.8% for mild migraine and 26.6% for mod-severe migraine and the proportions for preventive treatment were 8.1% for mild migraine and 12.0% for mod-severe migraine.

Conclusions
In this study, we combined survey data with EHR data to better understand treatment needs among patients diagnosed with migraine. Migraine-related disability is directly related to preventive treatment orders but less so for acute treatments. Estimates of treatment status by self-reported disability status were substantially over-estimated among those with moderate to severe migraine-related disability without correction for non-response bias.

Published: December 2021

AbstractProgress towards the achievement of the 17 Sustainable Development Goals (SDGs) of the 2030 Agenda for Sustainable Development in many ways presupposes the utilisation of science, technology and innovation. Many sustainability-oriented projects across industries make use of space-based technologies and services to contribute to the Goals. Among others, satellite-based Earth observation, positioning, navigation and communication services are used in an array of sectors ranging from monitoring environmental conditions and changes to supporting search and rescue missions. In order to illustrate contributions to the SDGs, space agencies and other institutions have aligned their projects to the SDG framework. This study attempts a more holistic, aggregate mapping of such alignments to gauge which SDGs benefit the most and from space-based projects and technologies, as opposed to those benefiting the least. The results demonstrate that the number of contributing projects varies significantly across the Goal spectrum, as does the share of the various technologies involved, with particular focus on industrial development, hunger elimination, and improved healthcare. Nevertheless, the range of application of space-based technologies is wide and highlights the relevance of space to support the transition towards a sustainable future.

Published: December 2021

Abstract
Background
Comparison of serratus anterior plane block to different analgesic methods for anterolateral thoracic wall incisions. Meta-analysis was used to address this concern. Authors systemically searched the MEDLINE, EMBASE, PubMed, and Cochrane databases to identify all published randomized and prospective clinical trials, comparing the SAPB with other methods that used for analgesia in different thoracic surgical procedures and trauma.

Results
Ten studies were identified for inclusion in this study, involving a total of 735 patients. Meta-analysis showed that, compared with thoracic wall analgesia and PCA methods, the SAPB group resulted in a significant decrease in pain scores, significant decrease in consumption of analgesic drugs, and a significant decrease in the incidence of nausea and vomiting with no difference in the rate of hypotension.

Conclusions
The use of SAPB in cardiothoracic surgery and trauma is a safe and effective option for thoracic analgesia.

AbstractBackgroundThe purpose of this study is to develop a theory-driven understanding of the barriers and facilitators underpinning physicians’ attitudes and capabilities to implementing SARS-CoV-2 point-of-care (POC) testing into primary care practices.MethodsWe used a secondary qualitative analysis approach to re-analyse data from a qualitative, interview study of 22 primary care physicians from 21 primary care practices across three regions in England. We followed the three-step method based on the Behaviour Change Wheel to identify the barriers to implementing SARS-CoV-2 POC testing and identified strategies to address these challenges.ResultsSeveral factors underpinned primary care physicians’ attitudes and capabilities to implement SARS-CoV-2 POC testing into practice. First, limited knowledge of the SARS-CoV-2 POC testing landscape and a demanding workload affected physicians’ willingness to use the tests. Second, there was scepticism about the insufficient evidence pertaining to the clinical efficacy and utility of POC tests, which affected physicians’ confidence in the accuracy of tests. Third, physicians would adopt POC tests if they were prescribed and recommended by authorities. Fourth, physicians required professional education and training to increase their confidence in using POC tests but also suggested that healthcare assistants should administer the tests. Fifth, physicians expressed concerns about their limited workload capacity and that extra resources are needed to accommodate any anticipated changes. Sixth, information sharing across practices shaped perceptions of POC tests and the quality of information influenced physician perceptions. Seventh, financial incentives could motivate physicians and were also needed to cover the associated costs of testing. Eighth, physicians were worried that society will view primary care as an alternative to community testing centres, which would change perceptions around their professional identity. Ninth, physicians’ perception of assurance/risk influenced their willingness to use POC testing if it could help identify infectious individuals, but they were also concerned about the risk of occupational exposure and potentially losing staff members who would need to self-isolate.ConclusionsImproving primary care physicians’ knowledgebase of SARS-CoV-2 POC tests, introducing policies to embed testing into practice, and providing resources to meet the anticipated demands of testing are critical to implementing testing into practice.
Fly ash-based geopolymers: an emerging sustainable solution for heavy metal remediation from aqueous medium
Authors: Gupta Piyush , Nagpal Garima , Gupta Namrata 
Published: December 2021

Abstract
Background
The water supplies are hindered because aquatic resources have constrained with natural and man-made pollution activities in terms of releasing huge amounts of contaminants from different point and non-point sources across the globe. The industries like metal plating, batteries, paint, fertilizers, tanneries, textile industries, dyeing industries, mining operations, and paper industries discharge their effluents into the environment directly or indirectly, and hence, they are considered as the key sources of heavy metals contamination in water resources. Heavy metals are inorganic, non-biodegradable, persistent, and having a tendency to get accumulated in biotic and abiotic components of environment as compared to organic pollutants. Some heavy metal cations, for example, mercury, arsenic, cadmium, zinc, lead, nickel, copper, and chromium, are carcinogenic in nature and so, lethal. There are growing health concerns due to toxic impacts of heavy metals on every genre of ecosystem. To deal with the bottleneck situation, it is highly imperative to search a feasible solution for heavy metal remediation in water in context of preventing amalgamation of noxious contaminants in food web. Different methods are exercised for the remediation of such impurities from its solutions. One method, i.e. adsorption is found to be the simplest, economical, efficient, and eco-friendly in this context.

Main body
Geopolymers exhibit heterogeneous amorphous microstructure and wide surface area. The compatibility for depollution and the performance of these materials mainly depend upon their preparation methods, composition, and microstructure. Fly ash-based geopolymer may serve as a better alternate to various cost-effective adsorbents and it will be a proven environmentally viable, waste to money solution by consuming heaps of fly ash waste for the adsorbent modified by using fly ash. The possible utilization of wastes from several industries is a matter of concerned sustainability benefits. This study shows that fly ash-based geopolymers have the potential to cope up with the problems and risk factors associated with the fly ash waste management and it would be the utmost scientific panacea in the field of removing toxins from aqueous medium and maintain environmental health in the future.

Short conclusions
The literature available in different databases is very limited pertaining to heavy metal remediation using fly ash-based geopolymers. Keeping all the factors in mind, this article is an attempt to summarize relevant informations related to work done on fly ash-based geopolymers for treating aqueous solutions comprising heavy metals.
DESCARTES E A TANGENTE A UMA CURVA
Authors: Pitombeira João Bosco 
Published: December 2021

A determinação das tangentes a curvas foi importante no século XVII e os matemáticos que precederam Newton e Leibniz, entre eles Roberval, Sluse, Fermat e Descartes desenvolveram vários métodos para isso. Bem geral, o método de Descartes permite, em princípio, determinar as tangentes a qualquer curva algébrica , embora as dificuldades técnicas possam aumentar muito. A regra de Hudde permite reduzir essas dificuldade

ALÉM DAS FRONTEIRAS: ORALIDADE E ESCRITA EM CONTOS DE JOSEFINA PLÁ E ÁNGELES MASTRETTA
Authors: Cruz Betania Vasconcelos da , Moreira Maria Elisa Rodrigues , Botoso Altamir 
Published: December 2021

O objetivo deste artigo é apontar interrelações entre a escrita, a oralidade e a cultura em contos das obras Cuentos completos I e II (2014), de Josefina Plá, e Maridos (2009), de Ángeles Mastretta. As duas escritoras, em suas obras, buscam interpretar a diversidade latino-americana e, partindo do nacional, atingem o universal, pela incorporação de elementos que caracterizam os seus países de origem, tais como gírias, línguas específicas de determinados povoados (yopará e mixteco), objetos relacionados a uma determinada nação, gêneros/grupos musicais que caracterizam uma região/país (mariachis) no enredo de suas produções ficcionais. Como suporte teórico utilizamos as obras de Édouard Glissant (2005), Antonio Candido (2006), Rubén Bareiro Saguier. (2000), dentre outros. Em suma, as narrativas de Plá e Mastretta representam uma linguagem multimodal mesclando o oral e o escrito, revelando as identidades e particularidades do contexto cultural paraguaio e mexicano através do processo comunicativo que é a escrita.

PRESCRIÇÕES CURRICULARES DE HISTÓRIA PARA OS ANOS INICIAIS: DIÁLOGOS ENTRE BASE NACIONAL COMUM CURRICULAR E CURRÍCULO DE PERNAMBUCO
Authors: Ferreira Danielle Da Silva 
Published: December 2021

Refletimos aqui sobre a Base Nacional Comum Curricular (BNCC) e o Currículo de Pernambuco da disciplina História, na medida em que este é parte do processo de consolidação daquele. A partir da análise das prescrições como fonte, problematizamos a organização do ensino de História para os anos iniciais no estado. Destacamos as leituras de Young (2014), Silva (2011) e Apple (2011) sobre o currículo e para o ensino de História Oliveira e Freitas (2018), Rüsen (2012), Cooper (2006) (2012) e Oliveira e Caimi (2014). A pesquisa foi qualitativa (LAKATOS e MARCONI, 2007) e documental (GIL, 2002). Concluímos que o Currículo de Pernambuco dialoga com a BNCC, sendo ao largo mais um instrumento de sua afirmação, do que de adequações às perspectivas de regionalização do ensino de História.
