Published: April 2021

BackgroundNews media coverage of antimask protests, COVID-19 conspiracies, and pandemic politicization has overemphasized extreme views but has done little to represent views of the general public. Investigating the public’s response to various pandemic restrictions can provide a more balanced assessment of current views, allowing policy makers to craft better public health messages in anticipation of poor reactions to controversial restrictions.ObjectiveUsing data from social media, this infoveillance study aims to understand the changes in public opinion associated with the implementation of COVID-19 restrictions (eg, business and school closures, regional lockdown differences, and additional public health restrictions, such as social distancing and masking).MethodsCOVID-19–related tweets in Ontario (n=1,150,362) were collected based on keywords between March 12 and October 31, 2020. Sentiment scores were calculated using the VADER (Valence Aware Dictionary and Sentiment Reasoner) algorithm for each tweet to represent its negative to positive emotion. Public health restrictions were identified using government and news media websites. Dynamic regression models with autoregressive integrated moving average errors were used to examine the association between public health restrictions and changes in public opinion over time (ie, collective attention, aggregate positive sentiment, and level of disagreement), controlling for the effects of confounders (ie, daily COVID-19 case counts, holidays, and COVID-19–related official updates).ResultsIn addition to expected direct effects (eg, business closures led to decreased positive sentiment and increased disagreements), the impact of restrictions on public opinion was contextually driven. For example, the negative sentiment associated with business closures was reduced with higher COVID-19 case counts. While school closures and other restrictions (eg, masking, social distancing, and travel restrictions) generated increased collective attention, they did not have an effect on aggregate sentiment or the level of disagreement (ie, sentiment polarization). Partial (ie, region-targeted) lockdowns were associated with better public response (ie, higher number of tweets with net positive sentiment and lower levels of disagreement) compared to province-wide lockdowns.ConclusionsOur study demonstrates the feasibility of a rapid and flexible method of evaluating the public response to pandemic restrictions using near real-time social media data. This information can help public health practitioners and policy makers anticipate public response to future pandemic restrictions and ensure adequate resources are dedicated to addressing increases in negative sentiment and levels of disagreement in the face of scientifically informed, but controversial, restrictions.

Introducción: La evaluación holística para competencias clínicas estomatológicas puede ser una buena herramienta para identificar rupturas entre objetivos de instrucción y su método de enseñanza.Objetivo: Proponer un diseño de evaluación holística como investigación evaluativa de tipo formativo, ecológico, naturalista, integrador para competencias clínicas del estomatólogo.Método: En un estudio de tipo educativo, experimental, prospectivo, comparativo, se analizó con métodos mixtos el alcance de una evaluación holística utilizando 8 indicadores. La muestra fue organizada por grupos (n = 4), alumnos (n = 72), docentes (n = 35) como grupos de interés involucrados en el proceso de enseñanza. Se instrumentó con observación etnográfica y entrevista a profundidad en los grupos de estudiantes y un cuestionario validado (alpha de Cronbach = .8660) aplicado al personal docente clínico.Resultados: Los grupos evaluados holísticamente incrementaron los tratamientos (Ts = 8.38, p = 0.001). El promedio grupal fue semejante (Ts = .235, p = 10). Relación pacientes tratados-tiempo clínico diario (4 horas cci = 0.586, p = .01). Actualización docente = 8.5%. Se realizó el análisis sintagmático del discurso del alumnado que reveló tiempo insuficiente, conflicto docente, evasión de responsabilidades, expectativas sobre calificaciones. El análisis mostró incongruencias entre administración-organización escolar, perfiles docentes inadecuados, y de ingreso insuficiente/dudoso. Expuso la ruta crítica del aprendizaje de competencias clínicas, los docentes desconocen/confunden los objetivos de los cursos clínicos y el proceso evaluativo.Conclusiones: La propuesta es efectiva para el logro del aprendizaje de las competencias clínicas. La metodología de tipo mixto permite una mejor interpretación del fenómeno y facilita la toma de decisiones.

Published: April 2021

Traditional Malay house is undergoing a lot of changes and threatened by modernization where its function, form and structure are affected. A lot of traditional Malay houses today are not considered as original vernacular houses where they are transformed and modernized into mixed design types between traditional and recent modern design. This paper aims to clarify modernization and alteration done, and new internal usage of selected four traditional Malay houses in two heritage villages: Kampung Banda Kaba and Kampung Sidang Seman, in Malacca. Interviews and field investigations were carried out at the selected houses that chosen based on the existing of original structure such as rumah ibu, rumah dapur and raised floor. Findings showed that all four traditional Malay houses had created a new usage style where the owners had altered and extend their houses based on their current needs and lifestyles.

Published: April 2021

Abstract

OBJECTIVE
To describe a modified approach to neurologic examination of African pygmy hedgehogs (Atelerix albiventris).

ANIMALS
12 adult hedgehogs (7 males and 5 females).

PROCEDURES
Aspects of the standard neurologic examination of dogs and cats were evaluated for use with awake hedgehogs, and modified approaches to evaluating their normal behavior and mentation, select cranial nerves and refexes, and gait were then identified. Behavioral analysis and gait analysis were performed by using video recordings of hedgehogs in a novel environment. Performability and repeatability of all feasible aspects of the neurologic examination were assessed.

RESULTS
Most aspects of the standard neurologic examination could be successfully performed, with repeatable results. However, certain aspects, especially those evaluating the pelvic limbs, were more difficult to perform successfully or were less repeatable. All hedgehogs lacked a menace response but displayed a contraction of the frontodorsalis muscle. Facial sensation testing was unreliable.

CONCLUSIONS AND CLINICAL RELEVANCE
The entire standard neurologic examination could not be performed in hedgehogs. However, many aspects could be performed, and together they provided baseline data for neurologic examination of this species.

Abstract

OBJECTIVE
To compare the rate of postoperative dehiscence on the basis of intraoperative anastomotic leak test results (ie, positive or negative for leakage or testing not performed) between dogs that underwent hand-sewn anastomosis (HSA) or functional end-to-end stapled anastomosis (FEESA) of the small intestine.

ANIMALS
131 client-owned dogs that underwent 144 small intestinal anastomoses (94 FEESA and 50 HSA).

PROCEDURES
Medical records were searched to identify dogs that had undergone a small intestinal anastomosis (HSA or FEESA) from January 2008 through October 2019. Data were collected regarding signalment, indication for surgery, location of the anastomosis, surgical technique, the presence of preoperative septic peritonitis, performance of intraoperative leak testing, development of postoperative dehiscence, and duration of follow-up.

RESULTS
Intraoperative leak testing was performed during 62 of 144 (43.1%) small intestinal anastomoses, which included 26 of 94 (27.7%) FEESAs and 36 of 50 (72.0%) HSAs. Thirteen of 144 (9.0%) anastomoses underwent dehiscence after surgery (median, 4 days; range, 2 to 17 days), with subsequent septic peritonitis, including 10 of 94 (10.6%) FEESAs and 3 of 50 (6.0%) HSAs. The incidence of postoperative dehiscence was not significantly different between FEESAs and HSAs; between anastomoses that underwent intraoperative leak testing and those that did not, regardless of anastomotic technique; or between anastomoses with positive and negative leak test results. Hand-sewn anastomoses were significantly more likely to undergo leak testing than FEESAs. Preoperative septic peritonitis, use of omental or serosal reinforcement, preoperative serum albumin concentration, and surgical indication were not significantly different between anastomotic techniques.

CONCLUSIONS AND CLINICAL RELEVANCE
Performance of intraoperative anastomotic leak testing, regardless of the anastomotic technique, was not associated with a reduction in the incidence of postoperative anastomotic dehiscence.

Wind Speed Distribution Direct Approximation by Accumulative Statistics of Measurements and Root-Mean-Square Deviation Control
Authors: Romanuke Vadim 
Published: April 2021

Abstract
In order to accurately estimate wind farm output and subsequently optimise it, a method of wind speed distribution approximation is suggested. The method is based on period-by-period accumulation of wind speed measurements, transforming them into empirical probabilities, and observing the moving approximation to the expected power produced by the wind turbine or entire wind farm. A year is a minimal term during which wind statistics are to be accumulated. The sufficient validity and reliability of the wind speed distribution approximation is supported by controlling root -mean-square deviations and maximal absolute deviations with respect to the moving average of the expected power. The approximation quality can be regulated by adjusting constants defining the requirements to the moving deviations.

Published: April 2021

Abstract
During the past decade, attacks by grey seals on fishing nets in the Baltic Sea have caused considerable loss of fish catch and damage to fishing gears. One of the approaches to reduce the number of seal attacks on fishing nets is to use acoustic deterrent devices (ADDs). Unfortunately, most of the commercially available ADDs are not well suited to the deployment in the sea and require considerable additional investments. The objective of the present research is to develop a compact and cost-efficient ADD for deployment in the sea environment. This paper is devoted to the design of acoustic signals for a prototype ADD. Signals from other experimental and commercially available ADDs are studied and compared. Moreover, limitations imposed by the underwater environment, transducers, battery power, and fish hearing are analysed and considered during the development of signal patterns. The results of tests conducted in an artificial reservoir and in the sea are presented.
Using heat as a potential groundwater Tracer through Stratigraphically Complex Media at the Victor Diamond Mine Site
Authors: Walker Cara 
Published: April 2021

The Victor Diamond Mine site near Attawapiskat, Ontario will begin mine development in the fall of 2007. The area around the site is characterized by two to three meters thick patterned peatland, which in turn is underlain by sand and silt, variable marine clay, and a large limestone bedrock aquifer. Bioherms, which are large, fractured limestone rocks that extend upward from the bedrock, to the surface in some cases, are complicating features to consider in the mine development planning. There is concern thatdewatering the aquifer for open pit mining may lead to disruptions in the surface peatlands due to draining through the bioherms. Dewatering the aquifer could impact the hydrological and ecological balance of the peatland, but the magnitude of the effect depends on the characteristics of the connections between the peatland and the underlying materials, which are currently unknown. A five year research program has commenced at the site to gain insight to the material behaviour and to study changes at the site asdevelopment progresses. This project will analyze the potential to use heat as a tracer for groundwater movement, and to integrate the findings into the long­term monitoring plan. Heat tracing may be used to test hypotheses for water movement at the site, and to detect areas of particular concern during dewatering. It is expected that collecting ormation about the site in this way and implementing monitoring plans will prevent, or at least anticipate, significant changes in the peatland ecosystem.
Body Modification and Popular Culture
Authors: Hogue Tarah 
Published: April 2021

Contemporary North America is obsessed with the body. Popular culture abounds with references to the body: from products for the body (hair care, teeth whitening products, clothing, etc.), to representations of the body (the black body, the gay body, the thin body). All of these things combine to create discourses surrounding the body, which are appropriated and then commodified in Western culture (a process known as hegemony). This is hugely significant to the formation of identity because the body underscores identity, and to modify the body is to negotiate in some way with identity. Plastic surgery, piercing, and tattooing are all practices of body modification that have been appropriated hegemonically by popular culture. The film Western Eyes explores the practice of plastic surgery within popular culture, and deals with the ways in which two women negotiate the discourses surrounding the practice. Tattooing and piercing are practices that mark the body in a different way than plastic surgery, and although they have been appropriated by popular culture, can still be discussed as important signifiers of identity and the body. Other more extreme practices, such as suspension, may completely resist the narratives of popular culturethat surround the body. In any case, it is clear that body modification is a complex issue that entwinesdiscourses of identity, the body, and popular culture. Although body modification is largely wrapped up in the production of ideal norms, there are ways to disrupt these narratives, which are important places of resistance of popular culture.
Fracta-­like Microreactor for Hydrogen Production
Authors: Gerson Jonas 
Published: April 2021

A catalyst micro­channel reactor using Cu/Alumina as the catalyst was designed in order to produce hydrogen from methanol in order to provide a fuel source to a hydrogen fuel cell to meet a power demand of 100W. To do this a branched channel micro­reactor design was employed. The reasoning for this was that the increased pressure drop due to the branching network and increased surface area of the reactor would produce a greater hydrogen yield then that of a straight channel reactor. The branched channel reactor showed a 10% greater hydrogen yield then that of the straight channel under three different conditions which the initial flow rate of methanol was varied. The final design of the reactor to meet the 100W power demand was a stack of 48 single branch disk units, each 17.5 mm in diameter, 1 mm thick, a constant channel depth of 250 µm, and a outlet channel width of 100 µm

Published: April 2021

Background. Middle ear neoplasm is a rare pathology accounting for about 0.7% total head and neck tumours. The article describes the clinical presentation, diagnostic methods and surgical treatment for neoplasms of mastoid process, a quite rare tumour localisation.Clinical Case Description. Patient G., 66 yo, was admitted to a otorhinolaryngological unit with a preliminary diagnosis of left mastoid neoplasm and complaints of non-transient headache on the left and slight hearing loss in both ears. The symptoms have been persisting since childhood. Laboratory tests without abnormalities. Voluminous invasive neoplasm of left temporal bone mastoid in CT. Left mastoidectomy with mastoid neoplasm resection was performed routinely, with a histological examination of surgical material. Benign angiofibroma in morbid histology. Definitive diagnosis: neoplasm of left mastoid. Relief from headache and overall improvement were reported by the patient in two months after surgery.Conclusion. Benign mastoid angiofibroma is a rare tumour in terms of localisation and morphology reluctant to diagnosis in an asymptomatic form. We suggest computed tomography as the main diagnostic and surgery — as main treatment method in this pathology. The disease has a life-favourable prognosis.
Blood and cell infiltrate neutrophilic leucocytes As inflammation markers in chronic endometritis: A prospective non-randomised controlled trial
Authors: Slavinsky A. A. , Chuprinenko L. M. , Verevkina V. S. , Sevostyanova E. S. 
Published: April 2021

Background. Inflammation declares itself with the presence of cellular tissue infiltrate, which composition reflects the inflammation type. Chronic inflammation is predominated by mononuclear cell infiltration with a certain amount of neutrophils, which role and significance are not fully understood to date.Objectives. Assessment of the infiltrated neutrophil count at various chronic endometritis severity and its dependency on the functional and metabolic activity in neutrophilic leucocytes in peripheral blood.Methods. This prospective non-randomised controlled trial estimated the CD45+ leucocyte and activated CD16b+ neutrophil counts in inflammation infiltrate using immunohistochemistry protocols. Cell counts per section 1 mm2 were measured with computer morphometry. The content of and NADPH oxidase activity in activated neutrophilic leucocytes in venous blood were estimated with a nitroblue tetrazolium reduction test.Results. The study included 40 women with a history of chronic endometritis (CE) divided in two cohorts by endometrial biopsy data, with inactive (n = 25) and active CE (n = 15). A control cohort comprised 20 women with no signs of CE. The inactive CE cohort had higher counts of CD45+ leucocytes and activated CD16b+ neutrophils in infiltrate compared to control. Higher content of activated neutrophilic leucocytes with higher NADPH oxidase activity were found in peripheral blood. Morphological exacerbation markers of EC were associated with sharper peaks of CD45+ and CD16b+ cell counts in infiltrate and an elevated functional metabolic activity in circulating neutrophilic leucocytes. A strong direct correlation was revealed between blood activated neutrophil and endometrial CD16b+ neutrophil counts, as well as NADPH oxidase activity in blood neutrophils and infiltrate CD16b+ cell counts.Conclusion. Even minor morphological markers of exacerbated endometrial inflammation are accompanied by the elevated infiltrate counts of both total CD45+ leucocytes and activated CD16b+ neutrophils. The functional metabolic activity of peripheral blood neutrophilic leucocytes is interlinked with the inflammatory infiltrate cell composition and reflects severity of chronic endometrial inflammation.
