description: Nowadays, protecting the environment and reducing harmful emissions is an increasingly discussed topic. One way to reduce vehicle emissions, especially for individual car traffic, is to use a hybrid drive. The advantages of the electric drive and the classic combustion engine are used here. By combining both types of drive, a synergetic effect is achieved, where both drives can be used in optimal operating mode. The aim of the experiment was to demonstrate the benefit of a hybrid vehicle in real driving. The operating parameters of the Lexus LX400h hybrid vehicle was compared to a conventional lowclass vehicle Škoda Fábia 1.2 HTP with a classic SI engine. The experiment took place on a route including typical urban, extra-urban and motorway traffic condition. During experiment, the engine operating parameters and CO, CO2, HC and NOX emissions were measured. The results show that the emission production and fuel consumption of the hybrid vehicle are significantly lower in urban traffic condition than the vehicle with classic internal combustion engine. On the contrary, in motorway conditions, the hybrid vehicle must use both drives, as higher performance is required to overcome higher driving resistances and therefore achieves higher fuel consumption and higher emissions than a conventional vehicle.

description: We present a general framework for performing "bold-line" diagrammatic Monte Carlo calculations based on using an analytical partial resummation as a starting point for stochastically summing all diagrams. As an example we solve the one orbital Anderson model using the non-crossing approximation as a starting point. We assess the accuracy of the method by using it to solve the equations of single-site dynamical mean field theory. We establish the validity of the starting approximations and show that the bold method provides a very accurate treatment of the Mott-insulating phase.

description: For successful implementation of the Precision Apiculture (Precision Beekeeping) approach, immense amount of bee colony data collection and processing using various hardware and software solutions is needed. This paper presents standalone wireless hardware system for bee colony main parameters monitoring (temperature, weight and sound). Monitoring system is based on Raspberry Pi 3 computer with connected sensors. Power supply is granted by the solar panel for reliable operation in places without constant source for power. For convenient data management cloud based data warehouse (DW) is proposed and developed for ease data storage and analysis. Proposed data warehouse is scalable and extendable and can be used for variety of other ready hardware solutions, using variety of data-in/data-out interfaces. The core of the data warehouse is designed to provide data processing flexibility and versatility, whereas data flow within the core is organized between data vaults in a controllable and reliable way. Our paper presents an approach for linking together hardware for bee colony real-time monitoring with cloud software for data processing and visualisation. Integrating specific algorithms and models to the system will help the beekeepers to remotely identify different states of their colonies, like swarming, brood rearing, death of the colony etc. and inform the beekeepers to make appropriate decisions/actions. This research work is carried out within the SAMS project, which is funded by the European Union within the H2020-ICT-39-2016-2017 call.

description: It is shown in this paper that the light field distribution in a band gap within periodic structures for one-dimensional photonic crystal fibers is described by a decaying factor multiplied by a periodical function that has the same period length as the one of the medium or has double the period length of the medium, depending on the sign of the trace of eigen value matrix. This fundamental property is applicable to any 1D planar periodic structures, no matter how many layers a unit cell has, what the contrast of refractive indices is, and whether the dielectric parameters in individual layers are homogeneous or inhomogeneous; it plays a significant role in understanding of numerical results in a number of previously published research works. It is also shown that, similar to the refractive index guidance in conventional optical fibers, the photonic band gap guidance is also a form of total internal reflection.

description: Background: Venous thromboembolism (VTE) is a notable but often ignored cause of disability and death. Improved public awareness of the symptoms and risks associated with VTE reduces the burden of disease. Aim: We aimed to determine the awareness of VTE among the general population. Methods: We conducted a population-based study using a pre-tested, pre-validated Ipsos-Reid questionnaire between October 2019 to March 2020. The questionnaire was distributed to consenting adults in the capital cities of Enugu and Ebonyi states of South-Eastern Nigeria to determine their awareness and knowledge of the symptoms and risk factors of VTE. Results: A total of 284 adults participated with a mean age of 32.73 ± 10.33 years and majority (70.8%) had a post-secondary education. While majority were aware of other medical conditions like a heart attack (96.1%), stroke (97.2%), diabetes (98.2%), HIV/AIDS (98.6%), cancer (97.2%) and malaria (98.2), just a few of the subjects were aware of thrombosis (41.5%) and DVT (33.8%). Less than half (42.4%) correctly described DVT as a blood clot in the vein and 13.7% of the respondents knew what PE feels like. A minority of them knew the risk factors of VTE included hospital stay (19.0%), surgery (37.2%), cancer (31.6%), pregnancy (31.6%) and old age (29.6%). Age and gender showed no statistically significant association with awareness of VTE, p value, 0.491 and 0.287, respectively. Conclusion: The awareness of VTE in the general population is low. Public awareness programs should be a public health priority to reduce morbidity and mortality associated with VTE.

description: The intrusion of infectious diseases in everyday life forces humans to reassess their attitudes. Indeed, pandemics are able catalyze rapid transitions in scientific knowledge, politics, social behaviors, culture and arts. The current Coronavirus diesease-19 (COVID-19) outbreak has driven an unprecedented interest toward the influenza pandemic of 1918. The issue is whether history can predict our best preventive response and future scenarios. The aim of this review is to highlight the parallelism between the two pandemics. Starting from epidemiology and clinical features, but further focusing on social and cultural issues, it is possible to unreveal great similarities. Their outbreak pattern lead to hypothesize a similar duration and death burden in absence of effective vaccines or innovative treatments for COVID-19. Thus, then as now, preventive medicine represents the first and most effective tool to contain the course of the pandemic; being treatments available only supportive. Contemporary, both pandemics shared the same pattern of narration (e.g. scapegoating) and the same impact on minorities in high-income countries. Furthermore, visual art did not wait to respond with Graffiti art playing in 2020 the role that Expressionism movement had during the Spanish flu and photography capable to document both catastrophic scenarios. Thus, it is possible to find a lot of clinical and social similarities between the two pandemics. Nevertheless, if the Spanish flu was not unforseen, COVID-19 spillover was partially predictable and its global impact will not be overshadowed by a major crisis such as World War I.

description: We demonstrate 'differential dynamic microscopy' (DDM) for the fast, high throughput characterization of the dynamics of active particles. Specifically, we characterize the swimming speed distribution and the fraction of motile cells in suspensions of Escherichia coli bacteria. By averaging over ~10^4 cells, our results are highly accurate compared to conventional tracking. The diffusivity of non-motile cells is enhanced by an amount proportional to the concentration of motile cells.
description: 4 pages, 4 figures. In this updated version we have added simulations to support our interpretation, and changed the model for the swimming speed probability distribution from log-normal to a Schulz distribution. Neither modification significantly changes our conclusions
Health warning messages on cigarette packs: how young smokers process it
Creators: name: Allahverdipour, Hamid
Publisher: name: Journal of Preventive Medicine and Hygiene
Year: 2021

description: Background: One of the major smoking prevention strategies has been to educate the public and increase people’s awareness, using health warning messages. However, many young people continue smoking without paying attention to health risk messages on cigarette packets in Iran. Hence, this study was conducted to examine the processing route of anti-smoking messages and influencing cognitive factors by using the Elaboration Likelihood Model. Study design: A case-control study. Methods: The non-probability sample for the cross-sectional study consisted of 387 tobacco smokers in the age range of 18 to 30 years old. This study was conducted between July and November of 2018 in Tabriz, Iran. A researcher-designed questionnaire was used for the purpose of data collection. No causal inferences were drawn due to the non-experimental nature of the study. Results: It was found that tobacco smokers often processed the health warning messages through the central route. Perceived severity, smoking abstinence self-efficacy, and psychological dependence were predictors of message processing through the central route. The results supported the conceptual model of cognitional predictors of the processing route. Conclusions: To design and execute effective health warning messages to quit smoking, it is recommended to consider cognitive factors as a means to enhance critical thinking about the content of the health warning message.

Astrometric Microlensing by Local Dark Matter Subhalos

description: High-resolution N-body simulations of dark matter halos indicate that the Milky Way contains numerous subhalos. When a dark matter subhalo passes in front of a star, the light from that star will be deflected by gravitational lensing, leading to a small change in the star's apparent position. This astrometric microlensing signal depends on the inner density profile of the subhalo and can be greater than a few microarcseconds for an intermediate-mass subhalo (Mvir > 10000 solar masses) passing within arcseconds of a star. Current and near-future instruments could detect this signal, and we evaluate SIM's, Gaia's, and ground-based telescopes' potential as subhalo detectors. We develop a general formalism to calculate a subhalo's astrometric lensing cross section over a wide range of masses and density profiles, and we calculate the lensing event rate by extrapolating the subhalo mass function predicted by simulations down to the subhalo masses potentially detectable with this technique. We find that, although the detectable event rates are predicted to be low on the basis of current simulations, lensing events may be observed if the central regions of dark matter subhalos are more dense than current models predict (>1 solar mass within 0.1 pc of the subhalo center). Furthermore, targeted astrometric observations can be used to confirm the presence of a nearby subhalo detected by gamma-ray emission. We show that, for sufficiently steep density profiles, ground-based adaptive optics astrometric techniques could be capable of detecting intermediate-mass subhalos at distances of hundreds of parsecs, while SIM could detect smaller and more distant subhalos.

description: Introduction. The Hypertension is a major risk for cardiovascular disease. Several studies have connected dairy consumption with lower blood pressure (BP). However, these have not considered the Latin American population. Aim. The aim of this study was to examine the relationship between consumption of full-fat or low fat/fat free dairy products and high blood pressure in Chilean adults. Methods. Cross-sectional study containing data from 3,807 adults between 20 and 98 years old from the National Health Survey (NHS) of Chile 2016-2017. The NHS is a nationally representative survey covering all 15 regions of Chile. Information on lifestyle, food frequency, and socio-demographics was collected using standardized questionnaires. Anthropometric and blood pressure measurements were taken by trained fieldworkers. Statistical analyses examined the association between the consumption of low fat/fat free dairy products or whole/full-fat dairy products with high blood pressure (defined as >160/90mmHg). Unadjusted associations were examined using X2 test and logistic regression models were adjusted for confounding variables. Results. Consumption of low fat/fat free dairy products (compared with whole/full fat dairy products) was protectively associated with high blood pressure in the unadjusted model (OR: 0.76, CI 95% 0.64-0.91). However, after adjustment for confounding variables, this association was attenuated (OR: 0.88; IC95% 0.71-1.08). Conclusion. We found limited evidence that the type of dairy products consumed is associated with high blood pressure in the Chilean population.

Local polynomial Lₚ norm regression
Creators: name: Tazik, Ladan
Publisher: name: University of British Columbia
Year: 2022

description: The local least-squares estimator for a regression curve cannot provide optimal results when non-Gaussian noise is present. Theoretically and empirically, there is evidence that residuals often exhibit distributional properties different from that of a normal distribution, so it is worth considering estimation based on other norms. It is suggested to use Lₚ-norm estimators to minimize the residuals when residuals have non-normal kurtosis. This thesis proposes local polynomial Lₚ-norm regression, which replaces weighted least-square estimation with weighted Lₚ norm estimation for fitting the polynomial locally. We investigate the performance of our proposed method when data depart from the normal distribution. Our technique shows good improvement on both simulated and real-life data compared to locally weighted least squares. Our study shows that our method can be a practical alternative to ordinary weighted least-squares when fitting local polynomials and can generalize well to regression data following different error distributions, including normal.

description: In this paper, we examine a supply chain consisting of a manufacturer and retailer where the manufacturer undertakes greening efforts in terms of pack-size reduction and transportation cost reduction. The retailer decides on shelf-space allocation for the product. Both the players benefit from the greening efforts of the manufacturer. In such a setting, we examine strategic decisions of the players and compare and contrast the performance of the decentralised supply chain with the centralised supply chain. We also examine the effect of collaborative mechanisms by modelling two contracts in which the retailer offers a transportation cost reduction effort based contract and a two-part tariff contract. We find that the decentralised supply chain leads to lower greening efforts and shelf-space allocation decisions. We also find that the contracts improve pack-size reduction effort, transportation cost reduction effort and shelf-space allocation, while also improving the profitability of individual players. The findings demonstrate a scope for supply chain collaboration between manufacturer–retailer pairs in this setting. The paper uniquely combines three critical elements in supply chains, namely, product design, transportation and retailing decisions, and aims to provide insights into the decision making of players considering environmental waste and pollution. The paper also reflects consumer behavior and trade-offs that the supply chain players face.

description: Recently Gliozzi has shown that, under certain conditions, it is possible to derive the Dirac-Born-Infeld action for an abelian gauge field of a D-brane. Also, the action turns out to be invariant with respect to a non-linear realization of the full Poincaré group. A crucial role is played by the transformation properties of the gauge field under the non-linear realization. The aim of this note is to point out that these transformation properties are derived directly from the gauge fixing of the diffeomorphisms of the brane and the necessary compensating reparametrization when one performs a Lorentz transformation.

description: Background: Saudi Arabia ranks the 4th country in the world in incidence rate of Type 1 Diabetes (T1D). It is usually diagnosed in children and teens. Managing T1D at school is important for children's short- and long-term health. Little is known about how much teachers are compatible to support students with diabetes in schools in northern Saudi Arabia. The aim of this study was to assess factual knowledge about T1D among teachers in public female elementary schools. Materials and methods: A cross-sectional survey approached teachers in 18 schools, systematically randomized among female elementary schools in Hail region (n=177). Results: A completed 504 questionnaires were received. Among all, 220 (43.7%) reported ever having a student/s with T1D in their classrooms. About one third (32.5%) reported that their schools conducted training programs regarding T1D, however, only 10.8% who attended such programs. Of the participants, only one in four who reported self-efficacy in recognizing signals of hypoglycemia in a diabetic student. Regardless that the participant attained an overall fair knowledge score (13.20 ± 3.81 on 20-point scale; 66.0%), yet, just 27.3% who attained a score (≥80%) considered compatible with being an effective support person for students with diabetes. Factors found to have independent positive association with teacher’s good knowledge were: received training (aOR 3.38; p<0.001), have/ever had diabetic student/s in his class (aOR 2.02; p=0.002), the teacher himself is diabetic or have a near contact diabetic person (aOR 2.35; p=0.001), family history of diabetes (aOR 1.84; p=0.015), and if the teacher can inject insulin (aOR1; p=0.003). Conclusion: Teachers in elementary schools in our region need to improve their knowledge about diabetes in children, especially recognizing and management of diabetic emergencies. Pre-service and ongoing professional learning are crucially needed to empower teachers with factual knowledge and self-confidence in helping students with diabetes.

Fatigue mitigation for position controlled floating offshore wind turbines
Creators: name: Saunders, Brendan
Publisher: name: University of British Columbia
Year: 2023

description: Improving the efficiency of electricity generation is an important component of reducing the cost of electricity. When using wind turbines to generate power, grouping them together results in losses in efficiency due to the wake effect. In order to counter those losses, it has been proposed that wind turbines in a floating offshore wind farm be dynamically repositioned to reduce wake interactions between turbines. However, this relocation strategy has raised concerns that fatigue may be increased. In response to these concerns, this thesis investigates the changes in lifetime fatigue at the tower base caused by adding position control to a Floating Offshore Wind Turbine (FOWT). The primary goal of this thesis is to answer the questions of how much the fatigue damage changes and how much the fatigue can be reduced. Building on previous works, a position controller is designed as a Proportional-Derivative (PD) controller which adjusts nacelle yaw in order to position the turbine in the crosswind direction. Then, the controller is tested with simulations in order to assess how the fatigue changes with its inclusion. Based on these results, a fatigue reducing controller is designed. This controller uses the Linear Quadratic Regulator (LQR) structure with the states in the model chosen based on the fatigue results of the position controller. Finally, the system with both position control and fatigue reduction is tested using the same environmental conditions as the position controller. When analyzing the effectiveness of the controllers with respect to fatigue, the results are compared to a baseline controller that has been designed for power capture. The results indicate that further tuning of the position controller is needed to improve station keeping, however, the controller is still reasonably successful at maintaining steady-state position. The position control goal also does not have a substantial impact on fatigue, but increases were noted in the side-to-side direction at the tower base. The fatigue controller shows success in reducing the increase in side-to-side fatigue. As well, the fatigue controller reduced lifetime fore-aft fatigue at the tower base by between 37 and 43 percent compared to the baseline.

description: We use entanglement to investigate the transition from vortex liquid phase to vortex lattice phase in weakly interacting rotating Bose-Einstein condensate (BEC). Ground state entanglement spectrum is analyzed to distinguish these two different phases. For the torus geometry, the low-lying part of ground state entanglement spectrum, as well as the behavior of its lowest level change clearly when the transition occurs. For the sphere geometry, the disappearance of entanglement gap in the conformal limit (CL) can indicate this transition. We also show that the decrease of entanglement between particles can be regarded as a signal of the transition.

description: We propose a scale dependent analytic approximation to the exact linear growth of density perturbations in Scalar-Tensor (ST) cosmologies. In particular, we show that on large subhorizon scales, in the Newtonian gauge, the usual scale independent subhorizon growth equation does not describe the growth of perturbations accurately, as a result of scale-dependent relativistic corrections to the Poisson equation. A comparison with exact linear numerical analysis indicates that our approximation is a significant improvement over the standard subhorizon scale independent result on large subhorizon scales. A comparison with the corresponding results in the Synchronous gauge demonstrates the validity and consistency of our analysis.

description: Background: Understanding of predictive factors for tobacco use initiation among adolescents is critical for effective intervention and prevention. In this regard, we aimed to determine the profile, examine associated factors, and show the regional disparities in the use of tobacco products among the youth in Ghana. Method: The study used the 2017 Ghana Global Youth Tobacco Survey (GYTS) to obtain tobacco-related information among adolescents in Junior High Schools across the country. The study used a 2-stage cluster randomized sampling technique to obtain nationally representative data. Weighted univariate and multivariate logistic regression analysis was used to assess the association of participant’s characteristics and use of tobacco. Results: Of 6039 targeted respondents, 5664 (93.8%) participated, - 2707 males, 2929 females, and 28 missing with gender. From the unadjusted analysis, age (p=0.001), pocket money (p<0.001), and exposure to SHS at home (p<0.001) were significantly associated with tobacco use. In the adjusted analysis, age (p=0.002), pocket money (p<0.001), exposure to SHS at home (p<0.001), and being taught about the dangers of tobacco use (p=0.043) were significantly associated with tobacco use. The regional disparities in the use of any tobacco product were 28.3%, 7.0%, and 4.8% in the Savanna/northern zone, middle/forest zone, and Coastal zone respectively. Conclusion: Multiple factors including age, pocket money, exposure to secondhand smoke (SHS) are identified to be associated with tobacco use among the youth in Ghana. Promoting anti-smoking campaigns in early adolescence, as well as programs targeting early tobacco use can guard the youth against initiating tobacco use.

description: The generic acceleration model for ultra high energy cosmic rays, which has been introduced in {\tt 1006.5708 [astro-ph.HE]}, suggests various types of electromagnetic interactions between cosmic charged particles and the different types of the plasma fields, which are assumed to have general configurations, spatially and temporally. The well-known Fermi acceleration mechanisms are also included in the model. Meanwhile Fermi mechanisms in non-relativistic limit adhere first- and second-order of $β$, the ratio of particle's velocity relative to the velocity of the stellar magnetic cloud, in the plasma field sector, $β$ does not play any role, i.e. zero-order. In the relativistic limit, the orders of Fermi acceleration are only possible, when applying the corresponding conditions, either elastic scatterings or shock waves. Furthermore, it is found that the coefficients of $β$ are functions of the initial and final velocities and the characteristic Larmor radius.

description: Deformations of quantum field theories which preserve Poincaré covariance and localization in wedges are a novel tool in the analysis and construction of model theories. Here a general scenario for such deformations is discussed, and an infinite class of explicit examples is constructed on the Borchers-Uhlmann algebra underlying Wightman quantum field theory. These deformations exist independently of the space-time dimension, and contain the recently studied warped convolution deformation as a special case. In the special case of two-dimensional Minkowski space, they can be used to deform free field theories to integrable models with non-trivial S-matrix.

description: Introduction We sought to identify determinants of preventive practice against COVID-19 at work among primary healthcare professionals in Sabah, Malaysia. Method This was a cross-sectional study involving healthcare workers of the Penampang and Putatan districts of Sabah, Malaysia. A total of 167 health professionals from primary healthcare settings took part in this study via a self-administered questionnaire. Independent t-test and Analysis of Variance were used to determine differences in preventive practice for categorical independent variables. Pearson product-moment correlation was applied to assess the relationship between Job Satisfaction, burnout, and preventive practice. Subsequently, predictors of preventive practice at work among healthcare workers in Sabah were identified through Binomial Logistic Regression. Results The prevalence of good preventive practice among health professionals at work was 71.3%. There was no difference in preventive practice between professions. Almost all participants reported having good personal protective equipment compliance and hand hygiene practice at work. Marital status, average sleep hours, job satisfaction, and pandemic-related burnout were identified as significant predictors of preventive practice at primary healthcare facilities. Conclusions The outcome of this study is beneficial to the healthcare organization. It can serve as a useful guide to tackle issues related to poor preventive practice against COVID-19 at work for health professionals.

description: Introduction: Considering the high prevalence of sexual dysfunction among women and the role of quality of sexual life in women's life and health, in addition to the important role of sexual function evaluation in measuring quality of life, this study aimed to determine the effect of female sexual function on the quality of sexual life. Material and Methods: This research was a descriptive and cross-sectional. The population of this study was 420 women from Qazvin in 2020, who were selected by multi-stage sampling. The data collection tool was a demographic questionnaire and Persian version of the Female Sexual Function Assessment questionnaire (FSFI) and Sexual Quality of Life Questionnaire (SQOL-F). Data were analyzed using SPSS 23, and descriptive statistics and logistic regression were applied. Results: The mean (SD) of sexual function score (83.4) was 56.21 out of 36, therefore, it was at an unfavorable level. Also, the mean (SD) score of sexual quality of life (21.19) was 71.59 out of 108 (moderate). The results of logistic regression test showed that the variables of sexual function, age and level of education of women were the factors affecting the quality of women's sexual life (p <0.05). Conclusions: Young women with lower sexual function, and lower level of education had lower quality of sexual life. Hence, it is necessary to pay more attention to these women in designing educational programs for improving the quality of their sexual life.

description: Introduction: Legionella spp. is a potential pneumonia causing pathogen, which can be transmitted to humans from water-supplying systems. Immunocompromised but also healthy individuals can be vitally threatened. Both, hot and cold-water supplying systems must be considered as transmission sources and therefore a periodic surveillance has to be performed in public buildings according to local legislations. During a routine surveillance, a hazardous colonization was detected within the cold-water supplying system at University Hospital Knappschaftskrankenhaus Bochum, Germany. Applied architectural measures remained unsatisfying in the reduction of legionella contamination of the cold-water distributing system. Methods: Adapted to an analysis of risks, effort and benefit, the superheat and flush procedure was applied twice with a time interval of 6 months. Results were evaluated concerning the efficiency and the sustainability and statistically analyzed. Results: While 33 out of 70 samples had a higher legionella count than the legal threshold of 100 CFU/100 mL (CFU - Colony Forming Units) before the first disinfection was carried out, this number could be reduced to 1 out of 202 samples after the first intervention. Additionally, in contrast to previously published studies, the effect was long-lasting, as no relevant limit exceedance occurred during the following observation period of more than two years. Conclusion: The superheat and flush disinfection can provide an economic and highly effective measure in case of legionella contamination and should be shortlisted for an eradication attempt of affected water-supplying systems in hospitals.

description: We construct a class of generalized phase coherent states indexed by points of the unit circle and depending on three positive parameters "gamma","alpha" and "epsilon" by replacing the labelling coefficients of the canonical coherent states by circular Jacobi polynomials with parameter "gamma". The special case "gamma" = 0 corresponds to well known phase coherent phase states. The constructed states are superposition of eigenstates of a one-parameter pseudoharmonic oscillator depending on "alpha" and solve the identity of the state Hilbert space at the limit "epsilon"->0+. Closed form for their wavefunctions are obtained in the case "alpha" = "gamma" + 1 and their associated coherent states transform is defined.

description: BACKROUND Cases of COVID-19 infection have increased sharply in Europe since August 2020, and the WHO and THL recommend the use of respirators in situations where keeping distance is not possible. The purpose of this study was to evaluate the impact of the use of respirators on infection cases and viral deaths in European countries. METHODS COVID-19 cases and related deaths in 29 countries relative to population were searched through the WHO database on 15.10.2020. Recent 14-day cases in relation to the population were retrieved from the European Center for Disease Prevention and Control's website, covering the period from 1 to 14 October 2020. Information related to the use of respirators was retrieved from the IHME database of the University of Washington at two time points, 1.6.2020 and 1.10.2020. RESULTS The proportion of people using of respirators at 1.6.2020 correlate negatively to the reported cases of disease (Rs=-0.528) and to deaths (Rs=-0.553). No significant correlation was found for recent cases or mortality. 1.10.2020 The situation did not correlate with cases or mortality. Countries with at least 60% respirator use did not differ from other countries. CONCLUSIONS Long-term use of respirators appears to reduce disease incidence and death in the population.
