Perspektif Kakitangan Hospital Terhadap Hukuman Hudud
Authors: Awang Azarudin
Published: May 2020

Hudud Law is a punishment prescribed by Allah s.w.t to be used as a guide to Muslim countries governments in prosecuting cases involving crimes. In 2015, the government of Kelantan proposed and approved for the implementation of this law and the same intention is also to be implemented by the government of Terengganu. This issue has raised various negative and positive perceptions among the Malaysian Muslim or non-Muslim. This study used purposive sampling to investigate the perception of civil servants, especially among hospital staff in Terengganu specifically in its implementation. This study distributed a total of 200 self-administered questionnaires to hospital staff Hulu Terengganu. The data analysis employed IBMSPSS 20 to obtain mean, percentage and frequency to elaborate the findings. The study found that most of the respondents viewed that Hudud should be implemented with the aim to prevent formidable criminals. Thus, this study also serves to reject the claim that the Hudud law is not relevant for implementation in the future Abstrak Hukuman hudud merupakan hukuman yang telah ditetapkan oleh Allah S.W.T untuk digunakan sebagai panduan kepada para pemerintah di negara Islam dalam mengadili kes-kes yang melibatkan jenayah. Pada tahun 2015, kerajaan negeri Kelantan mengusulkan dan meluluskan untuk melaksanakan undang-undang ini dan hasrat yang serupa juga ingin dilaksanakan oleh kerajaan negeri Terengganu. Perihal ini menimbulkan pelbagai persepsi negatif dan positif sama ada dalam kalangan masyarakat Muslim atau bukan Muslim di Malaysia. Kajian ini adalah bersifat kajian bertujuan (purposive sampling) dan objektif kajian ini dijalankan ialah untuk mengkaji persepsi penjawat awam khususnya dalam kalangan kakitangan hospital di negeri Terengganu terhadap pelaksanaan hukuman hudud di negara ini. Kajian ini menggunakan metodologi kuantitatif dengan sebanyak 200 borang soal selidik telah diedarkan kepada kakitangan hospital Hulu Terengganu. Data-data diukur dengan IBMSPSS 20 dengan menggunakan min, peratus dan kekerapan bagi menerangkan hasil kajian. Hasil kajian mendapati kebanyakkan responden berpandangan hukuman hudud wajar dilaksanakan dengan tujuan menggerunkan penjenayah. Justeru, kajian ini juga berperanan bagi menjelaskan bagi menolak dakwaan bahawa hukum hudud tidak relevan dilaksanakan pada masa kini.

Stolyarov ; Association of Russian School Librarians ; Library Science Department of the International Informatization Academy ; Russian State Library ; Book Culture Research Center of the Russian Academy of Sciences ; National Library of Sakha Republic (Yakutia). – Moscow : RUSLA, 2019. – 416 p. [In Russian]

In his new book, Yury N. Stolyarov reconstructs the biography of Nikolay [Nikolas] Aleksandrovich Rubakin, the author of over 280 books and 300 articles. The monograph is based on the series of papers by Stolyarov published in professional periodicals. The author includes Rubakin’s biography beginning with his birth in the town of Oranienbaum (now (Lomonosov, Leningradskaya oblast, Russia) till his last days in Switzerland. Yu. Stolyarov portrays a person who had to emigrate, though his all life was wholeheartedly devoted to Russia. The author investigates into archival materials, publications by the scholar, his personal correspondence, which enabled Stolyarov to demonstrate political, social and cultural impacts on Rubakin’s life and vectors of his studies. In his book, Stolyarov emphasizes the scholar’s great contribution to the study of problems in library science and bibliology, i. e. the role of libraries in self-education, promotion of science knowledge among population groups, collection development, book selection for children, reading theory, etc. Yu. Stolyarov also focuses on bibliopsychology — an independent discipline, developed by N. Rubakin and won the support of the library community. The findings of bibliopsychology has been being still used globally.
The corporate library activities in the organization structure
Authors: Romanova E. S.
Published: May 2020

The paper is based on the revealed domestic publications and analysis of vast publications in the foreign professional periodicals. Internet-based resources, e. g. www-sites of diverse organizations were analyzed, and the data on efficient Russian corporate libraries was identified. The national library studies exclude corporate libraries from the traditional official library typology. The national classification system (Library Bibliographic Classification, LBC) as well, does not envisage typology for the corporate libraries. The author does not possess statistical data. Some experts relate the concept to “corporations”, others see the corporate libraries as former “technical” (sectoral, industrial) libraries. However, the analysis findings demonstrate that this term can be primarily related to the concept of “corporate culture”. The corporate libraries make part of corporations, financial and trade companies, banks, foundations, joint-stock companies, etc. The prerequisites of extensive uprise of these libraries in Russia emerged in 1990s. The few publications on the topic are discussed along with the information available from Internet resources. The author concludes that the corporate libraries belong to special libraries, and within the latter group, the corporate libraries should be separated. Both state-funded and non-government organizations have got the libraries within their structure. The author attempts to formulate the definition for the new type of libraries, examines their functions and characteristic features, staff and users. The examples of the place of these libraries within the organizational structure are provided.
The bibliometrical analysis of document flow within the topic “Research methods” (based on VINITI RAS Abstracts Journal “Informatics”)
Authors: Sbitneva G. I. , Dvorovenko O. V.
Published: May 2020

Today the scientific research has become of increased significance for the library activities. This calls for implementing new research methods. The Abstracts Journal “Informatics” was analyzed for the publications on “Research methods” for the 10-year period; the findings are discussed, i.e. the rise of interest methods in the library and information community toward applying research, positive dynamics of the document flow with the 10-year doubling period. Over 100 research methods are identified. Thematically, the stable part of the document flows make approximately one-fifth of the total volume. Twenty three methods are used most frequently. The subject headings for these methods demonstrate stability which means permanent interest toward these methods and stable vectors of research methods development. Metric methods are dominating, including those being used in the digital environment. The increase of subject headings efficiency evidences on their increasing relevancy. Mobile document flows characterize the newest research methods. These are the methods being borrowed from other fields and used occasionally in the library and information studies. “The research methods” topic appears to be a trending and a developing one. The core methods are defined. Nevertheless, the major part of the document flow remains decentralized and comprises many new vectors that, while being quite relevant, have not found their niche in the library science research.

Leitura como prática social: mediação de leitura em uma sequência didática em torno de Dom Quixote
Authors: Costa Juliane Alves Araújo , Mello Cláudio José de Almeida
Published: May 2020

A aplicação de estratégias de leitura e a utilização de métodos de ensino da literatura concebida como prática social tornaram-se, sobretudo com a disseminação a partir da década de 1980 no Brasil da concepção interacionista de linguagem e da teoria da Estética da Recepção, foco de interesse de professores e pesquisadores motivados em promover a leitura literária. Inserido nesse contexto acadêmico e pedagógico, este trabalho apresenta alternativas para o desenvolvimento da leitura literária como prática social na perspectiva do letramento literário, utilizando estratégias e mediação de leitura para trabalhar o desenvolvimento de capacidades implicadas no processo de aprendizagem. Como ilustração da reflexão teórico-metodológica, apresenta-se uma abordagem de leitura com uma sequência didática (SD) para o ensino fundamental que poderá ser adequada a contextos reais e colocada em prática por professores, tendo como texto modelo Dom Quixote de Miguel de Cervantes e várias adaptações dessa obra. Nessa proposta, as contribuições dos âmbitos teóricos favorecem a equalização do binômio cognição-fruição, fundamentais para a promoção da leitura literária a partir da escola. O objetivo é explicitar como uma aproximação com diferentes produções literárias e gêneros textuais, de forma comparativa, pode propiciar o prazer do texto por meio da vivência da experiência estética, por um leitor autônomo. Conclui-se que por meio de um trabalho de mediação de leitura alicerçado na perspectiva do letramento, os estudantes podem ser motivados a ler, produzir sentidos e apropriar-se do texto literário de forma crítica, envolvendo o seu contexto social, na esteira do pensamento de Cosson, Colomer, Munita e Manresa.
Identidade, letramento e dialogismo nas aulas de Língua Portuguesa do 5º ano do Ensino Fundamental I
Authors: Dimbarre Mirely Christina , Saleh Pascoalina Bailon de Oliveira
Published: May 2020

A escola é um ambiente em que as identidades ditas sociais são (re)negociadas constantemente por meio das relações dialógicas. Em outras palavras, nessa esfera os encontros e o entrecruzamento de diálogos constituem e orientam os enunciados de alunos e de professores, uma vez que a linguagem é constitutivamente dialógica e, com isso, produzem sentido(s), resposta(s) e outro(s) enunciado(s). Dessa forma, o presente artigo tem como principal objetivo analisar como as (re)negociações das identidades são desenvolvidas em duas turmas de 5º Ano, do Ensino Fundamental I, da Rede Pública da cidade de Ponta Grossa/PR, nos eventos de letramento que se deram durante as aulas de Língua Portuguesa. Esse recorte destaca as relações dialógicas e as questões de alteridade desenvolvidas nas aulas de Língua Portuguesa, observando como os alunos (re)negociam suas identidades sociais. Para situar as questões de letramento, buscamos aporte em autores como Kleiman e Street; de dialogismo em Bakhtin; e de identidade em Hall e Moita Lopes. A metodologia baseou-se na pesquisa etnográfica e, para gerar os dados, centrou-se nas observações, as quais foram anotadas em um diário. Assim, como resultados obtidos, constatou-se que alunos e professoras, imersos nas relações dialógicas e de alteridade, (re)negociam suas identidades a partir das esferas sociais de que participam e em que transitam.

Authors: Fuza Ângela Francine , Striquer Marilúcia dos Santos Domingos , Ohuschi Márcia Cristina Greco
Published: May 2020

O trabalho com as multissemioses e os mecanismos de persuasão do gênero discursivo anúncio publicitário é necessário no âmbito escolar, conforme a Base Nacional Comum Curricular, a fim de que o aluno possa participar da vida em sociedade em todos os campos que a constitui. Este artigo objetiva apresentar uma proposta teórico-metodológica de ordenação e sequenciação de perguntas de leitura para este gênero, destinada ao segundo ano do Ensino Médio, a estabelecer um diálogo entre as perguntas de leitura e o conceito de exauribilidade temática, discutido pelo Círculo de Bakhtin. A metodologia de ordenação e sequenciação divide as perguntas de leitura em pergunta de resposta textual, inferencial e interpretativa, ou seja, alicerça-se sobre uma ordem crescente de dificuldade, em vistas de levar o leitor à progressiva reflexão sobre o texto e sobre o tema. Os resultados demonstram que, por meio da referida metodologia, é possível um trabalho que leve o aluno a exaurir de forma relativa o tema que constitui um texto, expandindo as ideias sobre o tema, construindo contrapalavra. Ao mesmo tempo, evidencia-se um trabalho que leve o aluno a conhecer e considerar as multissemioses que formam o anúncio publicitário, na ligação inseparável para a construção dos sentidos das multilinguagens.

La literatura ha mostrado terapias para el tratamiento de los síntomas relacionados con situaciones de abuso sexual infantil en adolescentes, jóvenes y adultos. La presente revisión se enfocó en intervenciones para niños víctimas de abuso sexual con edades entre los tres y los doce años. Nos enfocamos en publicaciones en inglés, español, francés y portugués registradas en las bases de datos Science direct, Jstor, Proquest, Redalyc y Scielo. Los resultados mostraron mayor frecuencia de estudio de este tema en poblaciones norteamericanas y europeas, enfocadas en el tratamiento de síntomas o consecuencias en la salud mental tales como baja autoestima, depresión y ansiedad, actitud vital negativa, trastornos alimentarios, estrés postraumático y otras variables relacionadas como bajo rendimiento académico, conductas auto lesivas o suicidas. La terapia cognitivo comportamental individual y grupal y también su modalidad centrada en el trauma, cuenta con una frecuencia mayor de estudios que demuestran su efectividad para el tratamiento. Igualmente se identifican la terapia psicodinámica de juego, la terapia asistida por animales y la terapia de interacción padre-hijo. Se discute el papel que podría jugar las terapias de tercera generación como complementarias para el manejo de los síntomas o consecuencias del abuso sexual en niños.
Burnout among Academic Clinicians as It Correlates with Workload and Demographic Variables
Authors: Nassar Aussama K. , Reid Susan , Kahnamoui Kamyar , Tuma Faiz , Waheed Abdul , McConnell Meghan
Published: May 2020

Burnout syndrome (BOS) in academic physicians is a psychological state resulting from prolonged exposure to job stressors. It leads to a decline in overall job performance, which could result in misjudgment and serious clinical errors. The current study identifies the prevalence, as well as the potential demographic and workload variables that contribute significantly to BOS in academic clinicians. We distributed a modified version of the Maslach Burnout Inventory (MBI) scale to the academic clinicians in our institution; 326/900 responded, with 56.21% male and 43.46% female. The MBI scale comprised of three dimensions of burnout: emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA). Higher scores in EE and DP and lower scores in PA were associated with a higher risk for burnout. In considering the work-life of academic clinicians, this study used a modified version of the MBI to reflect three hypothesized sources of burnout: interactions with students/trainees, interactions with patients, and interactions with administration, as reflected in these three dimensions. Along both the EE and DP dimensions of the MBI, burnout was highest for interactions with administration (51% and 44.8%), moderate for interactions with patients (26.4% and 34.5%), and lowest for interactions with students (11.7% and 9.8%). The highest scores along the personal accomplishment component was found for interactions with students and patients (33.7% and 33.4%). Regression analyses identified several factors associated with higher scores on the EE and DP scales: younger age, surgical specialty, low academic rank, academic main practice, female gender, numerous night shifts, and living alone. Furthermore, higher patient volume contributed significantly to the increasing PA. This study suggests that administrative interaction contributes significantly to burnout amongst physicians, followed by patient care and trainees. Furthermore, surgeons, females, single, early career, and younger faculty staff members are at higher risk of suffering from burnout. Further studies are needed to characterize the nature of administrative interactions that contribute to burnout and to solidify other contributing variables.
“Smart Process” of Medical Innovation: The Synergism Based on Network and Physical Space
Authors: Zhang Ailian , Pan Mengmeng
Published: May 2020

Medical innovation has a profound impact on public health, and it is always of social concern to encourage innovation and enhance the value in health care delivery. Based on a sample of China’s listed firms in the medical industry from 2007 to 2018, this paper highlights the independent and mixed roles of informatization and high-speed rail in public medical innovation. The results show that informatization at network space and high-speed rail at physical space effectively promote the innovation of medical enterprises. In addition, “online” information technology and “offline” high-speed rail technology have a synergistic effect on medical innovation, especially in areas with a low level of innovation. The conclusion supports the positive significance of technology in the application of public health and proposes that the construction of smart society is very important to public health.
In-Hospital Mortality in Patients Receiving Percutaneous Coronary Intervention According to Nurse Staffing Level: An Analysis of National Administrative Health Data
Authors: Kim Yunmi , Kim Jiyun
Published: May 2020

The increasing incidence of ischemic heart disease is concomitantly increasing percutaneous coronary intervention (PCI) treatments. Adequate nurse staffing has enhanced quality of care and this study was conducted to determine the relationship between survival-related PCI treatment and the level of nursing staff who care for patients admitted to receive PCI. National Health Insurance claims data from 2014 to 2015 for 67,927 patients who underwent PCI in 43 tertiary hospitals were analyzed. The relationships of nurse staffing in intensive care units (ICUs) and general wards with survival after PCI were investigated using logistic regression analyses with a generalized estimation model. The in-hospital mortality rate in ICUs was lower in hospitals with first-grade nurse staffing {odds ratio (OR) = 0.33, 95% confidence interval (CI) = 0.23–0.48}, second-grade nurse staffing (OR = 0.55, 95% CI = 0.40–0.77), or third-grade nurse staffing (OR = 0.71, 95% CI = 0.53–0.95) than in hospitals with fifth-grade nurse staffing. Nurse staffing in general wards was not related to in-hospital mortality due to PCI treatment. This study found that nurse staffing in PCI patients requiring short-term intensive care significantly affected patient survival. An understanding of the importance of managing the ICU nursing workforce for PCI treatment is required.
Long-Term Exposure to Low-Dose Di-(2-ethylhexyl) Phthalate Impairs Cholesterol Metabolism in Hepatic Stellate Cells and Exacerbates Liver Fibrosis
Authors: Lee Chun-Ya , Suk Fat-Moon , Twu Yuh-Ching , Liao Yi-Jen
Published: May 2020

Phthalates are often added to plastic products to increase their flexibility. Di-(2-ethylhexyl) phthalate (DEHP) is one of the most common plasticizers. Previously, a major incident involving phthalate-contaminated foodstuffs occurred, where phthalates were deliberately added to foodstuffs as a substitute for emulsifiers, resulting in a threat to public health. DEHP exposure can cause liver damage and further lead to cancer; however, the effects of long-term exposure to low-dose DEHP on hepatic stellate cells (HSCs) and on liver fibrosis are still unclear. In this study, we showed that chronic exposure to low-dose DEHP results in an accumulation of cholesterol in HSCs by disturbing the cholesterol metabolism and enhancing endogenous cholesterol synthesis. In addition, long-term exposure to low-dose DEHP reduces the sensitivity of HSCs to platelet-derived growth factor BB (PDGF-BB)-induced proliferation by blocking the MAPK pathway. Dysfunction of mitochondrial respiration and induction of caspase 3/PARP-dependent apoptosis were observed in HSCs following chronic, low-dose exposure. The carbon tetrachloride (CCl4)-induced liver fibrosis mouse model showed that long-term administration of DEHP significantly promoted liver damage, inflammatory infiltration, cholesterol accumulation, and deposition of hepatic collagen. In conclusion, long-term exposure to low-dose DEHP may perturb the cholesterol metabolism in HSCs and accelerate liver damage and fibrosis.

Changes in Provision of Psychotherapy in the Early Weeks of the COVID-19 Lockdown in Austria
Authors: Probst Thomas , Stippl Peter , Pieh Christoph
Published: May 2020

Reducing personal contacts is a central measure against the spreading of the novel coronavirus disease (COVID-19). This troubles mental health, but also mental health care as treatments usually take place in personal contact and switching to remote treatments might be necessary in times of COVID-19. The present study investigated the question how the provision of psychotherapy changed in the early weeks of the COVID-19 lockdown in Austria and whether there were differences between the four therapeutic orientations eligible in Austria (psychodynamic, humanistic, systemic, behavioral). Psychotherapists (N = 1547) completed an online survey. They entered their number of patients treated on average per week (in personal contact, via telephone, via Internet) in the early weeks of the COVID-19 lockdown in Austria as well as (retrospectively) in the months before. The number of patients treated on average per week in personal contact decreased (on average 81%; p < 0.001), whereas the number of patients treated on average per week via telephone and via Internet increased (on average 979% and 1561%; both p < 0.001). Yet, the decrease of psychotherapies through personal contact was not compensated for by increases of remote psychotherapies (p < 0.001). No differences between the four therapeutic orientations emerged. Results imply an undersupply of psychotherapy in the COVID-19 lockdown and that further changes are necessary to cover the increased need for timely psychotherapy in times of COVID-19.

Mindfulness as a Protective Factor for Dissatisfaction in HCWs: The Moderating Role of Mindful Attention between Climate Stress and Job Satisfaction
Authors: Ramaci Tiziana , Rapisarda Venerando , Bellini Diego , Mucci Nicola , De Giorgio Andrea , Barattucci Massimiliano
Published: May 2020

With the aim of investigating the possible moderating effect of job control and dispositional mindfulness between different sources of organizational stress and job satisfaction, a correlational study was designed involving health care workers (HCWs). The following questionnaires were administered and completed by 237 HCWs: (1) Occupational Stress Indicator (OSI), to measure the sources of stress at work (managerial role, climate power, climate structure, internal relationships), and job satisfaction; (2) Mindfulness Attention Awareness Scale (MAAS) to assess the individual’s level of attention to what is taking place in the present; (3) Job Control Scale (JCS) to assess the perceived control at work. Hierarchical regression analyses were used to test the hypothesized relationships between variables; the results showed that, between the different sources of stress, the organizational climate dimension was negatively associated with job satisfaction; moreover, mindfulness attention moderated the relationship between climate stress and job satisfaction; unexpectedly, the interaction between job control and the organizational climate dimension was not significant in affecting job satisfaction. This study can provide useful information for Human Resources Management (HRM) practices regarding job and mental control interventions and empowerment, and possibly offer a new interpretation of the role of attention to what is happening in the present moment and autonomy between climate stressors and occupational satisfaction.
Robotics Utilization for Healthcare Digitization in Global COVID-19 Management
Authors: Khan Zeashan Hameed , Siddique Afifa , Lee Chang Won
Published: May 2020

This paper describes the evolving role of robotics in healthcare and allied areas with special concerns relating to the management and control of the spread of the novel coronavirus disease 2019 (COVID-19). The prime utilization of such robots is to minimize person-to-person contact and to ensure cleaning, sterilization and support in hospitals and similar facilities such as quarantine. This will result in minimizing the life threat to medical staff and doctors taking an active role in the management of theCOVID-19 pandemic. The intention of the present research is to highlight the importance of medical robotics in general and then to connect its utilization with the perspective of COVID-19 management so that the hospital management can direct themselves to maximize the use of medical robots for various medical procedures. This is despite the popularity of telemedicine, which is also effective in similar situations. In essence, the recent achievement of the Korean and Chinese health sectors in obtaining active control of the COVID-19 pandemic was not possible without the use of state of the art medical technology.
COVID-19 Outbreak in North Italy: An Overview on Dentistry. A Questionnaire Survey
Authors: Cagetti Maria Grazia , Cairoli Jean Louis , Senna Andrea , Campus Guglielmo
Published: May 2020

This survey assessed the symptoms/signs, protective measures, awareness, and perception levels regarding COVID-19 among dentists in Lombardy, Italy. Moreover, an analysis of the answers gathered in areas with different prevalence of the disease was carried out. All Lombardy’s dentists were sent an online ad hoc questionnaire. The questionnaire was divided into four domains: personal data, precautionary measures (before patient arrival; in the waiting room; in the operating room), awareness, and perception. Three thousand five hundred ninety-nine questionnaires were analyzed. Five hundred two (14.43%) participants had suffered one or more symptoms referable to COVID-19. Thirty-one subjects were positive to the virus SARS-CoV-2 and 16 subjects developed the disease. Only a small number of dentists (n = 72, 2.00%) were confident of avoiding infection; dentists working in low COVID-19 prevalence areas were more confident than those working in the Milan area and high prevalence area (61.24%, 61.23%, and 64.29%, p < 0.01 respectively). The level of awareness was statistically significantly higher (p < 0.01) in the Milan area (71.82%) than in the other areas. This survey demonstrated that dentists in the COVID-19 highest prevalence area, albeit reported to have more symptoms/signs than the rest of the sample, were the ones who adopted several precautionary measures less frequently and were the more confident of avoiding infection.
Cannabinoid Receptor Type 2: A Possible Target in SARS-CoV-2 (CoV-19) Infection?
Authors: Rossi Francesca , Tortora Chiara , Argenziano Maura , Di Paola Alessandra , Punzo Francesca
Published: May 2020

In late December 2019, a novel coronavirus (SARS-CoV-2 or CoV-19) appeared in Wuhan, China, causing a global pandemic. SARS-CoV-2 causes mild to severe respiratory tract inflammation, often developing into lung fibrosis with thrombosis in pulmonary small vessels and causing even death. COronaVIrus Disease (COVID-19) patients manifest exacerbated inflammatory and immune responses, cytokine storm, prevalence of pro-inflammatory M1 macrophages and increased levels of resident and circulating immune cells. Men show higher susceptibility to SARS-CoV-2 infection than women, likely due to estrogens production. The protective role of estrogens, as well as an immune-suppressive activity that limits the excessive inflammation, can be mediated by cannabinoid receptor type 2 (CB2). The role of this receptor in modulating inflammation and immune response is well documented in fact in several settings. The stimulation of CB2 receptors is known to limit the release of pro-inflammatory cytokines, shift the macrophage phenotype towards the anti-inflammatory M2 type and enhance the immune-modulating properties of mesenchymal stromal cells. For these reasons, we hypothesize that CB2 receptor can be a therapeutic target in COVID-19 pandemic emergency.
A Metric Learning-Based Univariate Time Series Classification Method
Authors: Song Kuiyong , Wang Nianbin , Wang Hongbin
Published: May 2020

High-dimensional time series classification is a serious problem. A similarity measure based on distance is one of the methods for time series classification. This paper proposes a metric learning-based univariate time series classification method (ML-UTSC), which uses a Mahalanobis matrix on metric learning to calculate the local distance between multivariate time series and combines Dynamic Time Warping(DTW) and the nearest neighbor classification to achieve the final classification. In this method, the features of the univariate time series are presented as multivariate time series data with a mean value, variance, and slope. Next, a three-dimensional Mahalanobis matrix is obtained based on metric learning in the data. The time series is divided into segments of equal intervals to enable the Mahalanobis matrix to more accurately describe the features of the time series data. Compared with the most effective measurement method, the related experimental results show that our proposed algorithm has a lower classification error rate in most of the test datasets.

Advanced thermoplastic composites manufacturing using laser assisted tape placement or winding (LATP/LATW) is a challenging task as monitoring and predicting nip point (bonding) temperature are difficult especially on curved surfaces. A comprehensive numerical analysis of the heat flux and temperature distribution near the nip point is carried out in this paper for helical winding of fiber reinforced thermoplastic tapes on a cylindrically shaped mandrel. An optical ray-tracing technique is coupled with a numerical heat transfer model in the process simulation tool. The developed optical-thermal model predictions were compared with experimental data available in literature to validate its effectiveness. The influences of winding/placement angle, mandrel curvature and tape width on the incident angles, the laser absorbed intensity, and the process temperature distribution are studied extensively using the validated model. Winding/placement angle has a considerable effect on the temperature distribution. Increase in winding angle results in a higher temperature for tape due to more reflections coming from the substrate. On the other hand, substrate temperature decreases as the winding angle increases due to a decrease in the laser incident angles based on the local surface curvature. An increase in mandrel curvature results in higher nip point temperatures for substrate and lower one for tape. Different mandrel sizes for 90 ° placement path do not have a strong effect on the substrate process temperature as for other winding angles because of less curvature change of the corresponding irradiated area. Tape width causes local temperature variations at the edges of the tape/substrate. In order to obtain the desired process temeprature during LATW or LATP processes, the laser intensity distribution on the tape and substrate surfaces should be regulated.

This research work analyses the influence of the use of by-products from a fluorite mine to replace the fine fraction of natural aggregates, on the properties of Ultra-High-Performance Fibre-Reinforced Concrete (UHPFRC). Replacing natural aggregates for different kinds of wastes is becoming common in concrete manufacturing and there are a number of studies into the use of waste from the construction sector in UHPFRC. However, there is very little work concerning the use of waste from the mining industry. Furthermore, most of the existing studies focus on granite wastes. So, using mining sand waste is an innovative alternative to replace natural aggregates in the manufacture of UHPFRC. The substitutions in this study are of 50%, 70% and 100% by volume of 0–0.5 mm natural silica sand. The results obtained show that the variations in the properties of consistency, compressive strength, modulus of elasticity and tensile strength, among others, are acceptable for substitutions of up to 70%. Therefore, fluorite mining sand waste is proved to be a viable alternative in the manufacturing of UHPFRC.

The application of ultra-precision shaft parts is widely used, such as the spindle core of the air bearing spindle in ultra-precision machine tools. The precision of the spindle core is extremely high, and it is very difficult to obtain directly by traditional Computer Numerical Control (CNC) machine tools but is mostly obtained by manual grinding, whose machining efficiency is greatly limited. Based on the deterministic figuring theory, this paper focuses on the ultra-precision roundness, optimizing the filtering parameters of the measurement error data and studying the generation mechanism of the removal function morphology; the shape of the removal function is adjusted by combining the analysis of the figuring ability and positioning error. Finally, the optimized removal function is used on an experimental steel shaft, the average roundness convergence ratio is 72% higher than that of the original removal function, and the roundness reaches a 0.1 μm level. The result shows that a reasonable filtering of measured data and the removal function adjusted for the surface feature can improve the efficiency and precision of deterministic figuring on shaft parts.
Effect of Stochastic Loading on Tensile Damage and Fracture of Fiber-Reinforced Ceramic-Matrix Composites
Authors: Li Longbiao
Published: May 2020

In this paper, the effect of stochastic loading on tensile damage and fracture of fiber-reinforced ceramic-matrix composites (CMCs) is investigated. A micromechanical constitutive model is developed considering multiple damage mechanisms under tensile loading. The relationship between stochastic stress, tangent modulus, interface debonding and fiber broken is established. The effects of the fiber volume, interface shear stress, interface debonding energy, saturation matrix crack spacing and fiber strength on tensile stress–strain curve, tangent modulus, interface debonding fraction and fiber broken fraction are analyzed. The experimental tensile damage and fracture of unidirectional and 2D SiC/SiC composites subjected to different stochastic loading stress are predicted. When fiber volume increases, the initial composite strain decreases, the initial tangent modulus increases, the transition stress for interface debonding decreases and the initial fiber broken fraction decreases. When fiber strength increases, the initial composite strain and fiber broken fraction decrease.
Reflection-Like Maps in High-Dimensional Euclidean Space
Authors: Huang Zhiyong , Li Baokui
Published: May 2020

In this paper, we introduce reflection-like maps in n-dimensional Euclidean spaces, which are affinely conjugated to θ : ( x 1 , x 2 , … , x n ) → 1 x 1 , x 2 x 1 , … , x n x 1 . We shall prove that reflection-like maps are line-to-line, cross ratios preserving on lines and quadrics preserving. The goal of this article was to consider the rigidity of line-to-line maps on the local domain of R n by using reflection-like maps. We mainly prove that a line-to-line map η on any convex domain satisfying η ∘ 2 = i d and fixing any points in a super-plane is a reflection or a reflection-like map. By considering the hyperbolic isometry in the Klein Model, we also prove that any line-to-line bijection f : D n ↦ D n is either an orthogonal transformation, or a composition of an orthogonal transformation and a reflection-like map, from which we can find that reflection-like maps are important elements and instruments to consider the rigidity of line-to-line maps.
Ammoniacal System Mechanisms for Leaching Copper from Converter Slag
Authors: Aracena Alvaro , Valencia Andrés , Jerez Oscar
Published: May 2020

In pyrometallurgical processes refining copper, the main source of loss in the conversion stage is from slag. This paper reports on research work treating converter slag containing high percentages of copper (36 wt%) using ammonium hydroxide at room temperature. Variables analyzed are solution pH, agitation, temperature, NH4OH concentration and particle size. Results showed that the hydronium ion resulting from ammonium hydroxide dissociation was the main oxidant of copper compounds in slag, such as CuO, Cu2O and Cu, with the exception of CuFeO2. The particles contain a large amount of microcracks (porosity) in their refractory structure (analyzed by compositional image capture (BSE)). Thus, the diffusion of the leaching solution through the microcracks making contact with the copper oxides would be allowed. Leaching mechanisms were corroborated by X-ray diffraction and scanning electron microscopy analysis. Increasing temperature and NH4OH concentration while decreasing particle size obtained higher copper recoveries, reaching values of 84.8%. Under the same conditions, the main impurity (iron) was minimal (<2%). Solution pH also affected slag leaching. Agitation of the solution positively affected the rate of copper extraction. Leaching kinetics of the leaching solution through the porosity formed in the slag was analyzed under the intraparticle diffusion model. The reaction order was 1.2 with respect to the concentration of ammonium hydroxide and the model was inversely proportional to the square of the particle radius. The activation energy obtained was 42.3 kJ/mol for temperature range 283 to 333 K.

Retinal implant devices are becoming an increasingly realizable way to improve the vision of patients blinded by photoreceptor degeneration. As an electrode material that can improve restored visual acuity, carbon nanotubes (CNTs) excel due to their nanoscale topography, flexibility, surface chemistry, and double-layer capacitance. If vertically aligned carbon nanotubes (VACNTs) are biocompatible with retinal neurons and mechanically robust, they can further improve visual acuity—most notably in subretinal implants—because they can be patterned into high-aspect-ratio, micrometer-size electrodes. We investigated the role of an aluminum (Al) underlayer beneath an iron (Fe) catalyst layer used in the growth of VACNTs by chemical vapor deposition (CVD). In particular, we cultured dissociated retinal cells for three days in vitro (DIV) on unfunctionalized and oxygen plasma functionalized VACNTs grown from a Fe catalyst (Fe and Fe+Pl preparations, where Pl signifies the plasma functionalization) and an Fe catalyst with an Al underlayer (Al/Fe and Al/Fe+Pl preparations). The addition of the Al layer increased the mechanical integrity of the VACNT interface and enhanced retinal neurite outgrowth over the Fe preparation. Unexpectedly, the extent of neurite outgrowth was significantly greater in the Al/Fe than in the Al/Fe+Pl preparation, suggesting plasma functionalization can negatively impact biocompatibility for some VACNT preparations. Additionally, we show our VACNT growth process for the Al/Fe preparation can support neurite outgrowth for up to 7 DIV. By demonstrating the retinal neuron biocompatibility, mechanical integrity, and pattern control of our VACNTs, this work offers VACNT electrodes as a solution for improving the restored visual acuity provided by modern retinal implants.

Background: The aim of this study was to investigate the pharmacokinetic (PK) and safety profile of high-dose vitamin D supplementation, comparing different schedules (daily, weekly, or bi-weekly) in an otherwise healthy vitamin D-deficient population. Methods: Single-center, open-label study on healthy subjects deficient in vitamin D (25 (OH)D < 20 ng/mL), randomized to receive cholecalciferol (DIBASE®, Abiogen Pharma, Italy) using three different schedules: Group A: 10,000 IU/day for eight weeks followed by 1000 IU/day for four weeks; Group B: 50,000 IU/week for 12 weeks, Group C: 100,000 IU/every other week for 12 weeks. Total cumulative doses were: 588,000 IU, 600,000 IU, 600,000 IU. The treatment regimens corresponded to the highest doses allowed for cholecalciferol for the correction of vitamin D deficiency in adults in Italy. Results: mean 25 (OH)D plasma levels significantly increased from baseline 13.5 ± 3.7 ng/mL to peak values of 81.0 ± 15.0 ng/mL in Group A, 63.6 ± 7.9 ng/mL in Group B and 59.4 ± 12 ng/mL in Group C. On day 28, all subjects showed 25 (OH)D levels ≥20 ng/mL and 93.1% had 25 (OH)D levels ≥30 ng/mL. On day 56 and 84, all subjects had 25 (OH)D levels ≥30 ng/mL. No serious adverse events occurred during the study. Conclusions: normalization of 25 (OH)D serum levels was quickly attained with all the studied regimens. A more refracted schedule provided a higher systemic 25 (OH)D exposure.
