Dimensões do instante: mídia, narrativas híbridas e experiência urbana
Authors: Gomes Renato Cordeiro 
Published: March 2023

As transformações da modernidade produzem um clima de superestimulação, que modifica a percepção humana, condicionada pelo excesso de estímulos exteriores e pelas novas tecnologias. Tal fenômeno relacionase à fixação do instante da vida urbana, captado em meio ao ambiente de sensações fugazes, em face do caráter efêmero da modernidade. Com base nessas premissas, busca-se estudar as relações entre tecnologias, instante e metropolização, ou seja, entre mídia e vida urbana. Privilegia-se o início do século XX, no Brasil, que passava pelo processo de modernização, a partir do projeto republicano. Nesse contexto, destaca-se a imprensa escrita, em especial a crônica de João do Rio, cuja coluna “Cinematographo” da Gazeta de Notícias revela como o diálogo com o cinema afeta a produção do discurso e do gênero que fixa o instante
do cotidiano do Rio de Janeiro em transformação. Essa mesma analogia com o cinema condiciona o relato de viagem a cidades européias que Alcântara Machado escreveu para o Jornal do Comércio de São Paulo, em 1925. A experiência urbana é, então, representada em narrativas híbridas que a mídia impressa veicula. Esse cinema escrito ganha novo sentido quando é rearticulado em outro suporte material, como o livro.

ABSTRACT
The transformations in modernity trigger an air of overstimulation that modifies human perception, conditioned by the excess of exterior stimuli and new technologies. This phenomenon is related to the fixation of the instant in urban life, captured in the midst of fugative sensations due to the ephemeral character of modernity. Based on these standpoints, this text aims to study the relations between technologies, instant and metropolization, that is, between media and urban life. As a priority, we examine the beginning of the 20th Century, in Brasil, which was undergoing the process of modernization based on its republican project. Within this context, we highlight the written press, specially the João do Rio chronicles, whose column “ Cinematographo” at the paper Gazeta de Notícias reveals how the dialogue with the cinema affects discourse and genre production that fixes the everyday instant of transforming Rio de Janeiro. The same analogy with the cinema conditions the travel tales to european cities written by Alcântara Machado for the Jornal do Comércio from São Paulo, in 1925. The urban experience is, then, represented by hibrid narratives that the media presents. This type of written cinema acquires a new meaning
when it is re-articulated in a new material form such as the book .
Keywords: Technologies; instant and modernity; metropolization and urban

Published: March 2023

The article presents studies of double-sided solar modules in Kazakhstan. To conduct an experimental research of double-sided solar modules efficiency in the climatic conditions of Central Kazakhstan we have created an experimental solar power plant (SPP) located on the territory of Karaganda State Technical University. The solar power plant consists of four photovoltaic modules of KZ PV 270 M72 type and four photovoltaic modules of FSM-185D type. The rotary system was not used; solar panels are southward (directed to the south). The comparison was made with the solar power plant without orientation system which uses four photovoltaic modules of KZ PV 270 M72 type produced by Astana Solar LLP.
The statistical analysis of information with an assessment of parameters of distribution and criteria for processing of results of scientific experiment is carried out. The correlation and regression analysis is performed. The least square method (coefficient calculation) is used in data processing. We have developed the computational model simulating the SPP by means of which the theoretical averaged values of energy amount generated in kWh/day have been obtained, and the actual values have been received by in-use measurements of SPP parameters within a year. The results of this work showed that the use of double-sided solar modules in Kazakhstan is very promising and can be a decisive factor for their widespread use with the tendency to lower prices.

Published: March 2023

The paper studies the penetration of nitrogen, oxygen, hydrogen, carbon, argon and krypton into copper, nickel, molybdenum, titanium, aluminum, iron and different steels under the action of spark discharges in various media based on radioactive indicators using step-by-step radiometric analysis, macro-, micro-, electron-microscopy and activation autoradiography, Mössbauer and Auger spectroscopy, secondary ion-ionic emission, X-ray diffraction and X-ray microanalysis. The study describes distribution features of penetrating atoms and their concentration profiles. Phase composition of near-surface layers is also determined. It is shown that supersaturated solid solutions of iron in copper and copper in iron are formed during simultaneous iron and oxygen penetration in copper and spinel (Fe6Cu3O4)4. Diffusion of iron and carbon results in supersaturated solid solutions of iron and carbon in copper, copper and carbon in iron, graphite and cementite. Inert gases and nitrogen form solid solutions with copper. Phase composition of near-surface layers in Fe is determined. Iron dioxide FeO, a carbon solid solution in iron with fcc lattice γ-Fe, tetragonal martensite and cementite, two iron (III) hydroxide FeOOH modifications, a supersaturated solid solution of nitrogen and nitride Fe4N, solid solutions of inert gases in iron are formed in the diffusion zone. Simultaneous interaction of molybdenum with iron (the anode material) and various gases results in the formation of substitutional solid solutions of iron in molybdenum and molybdenum in iron, a small amount of interstitial solid solutions of nitrogen and carbon in molybdenum and nitrogen in iron, interstitial phases: molybdenum nitrides and carbides and traces of nitrides of iron (Fe4N, Fe2N) and Fe1,9Mo (λ) phases in the form of needles. Treatment of nickel with a nickel anode in the nitrogen medium promotes formation of a solid solution of nitrogen and nitride Ni3N in the matrix with preserved hexagonal symmetry and lattice parameters that are characteristic of this phase under equilibrium conditions. Atoms of oxygen, nitrogen, carbon and argon are present in the interstitial solid solutions in treatment of nickel in ambient air; however, oxides are not found even on the surface (in the layer ~200 nm). Interaction of titanium with atmospheric gases leads to formation of a solid solution of nitrogen, oxygen, carbon, hydrogen and argon in titanium and titanium nitride Ti2N (ε). Simultaneous saturation of the titanium surface with nickel and nitrogen in the interaction zone causes formation of phases in the following order: nickel nitride; a solid solution of nitrogen and titanium in nickel and a solid solution of both alloying elements in titanium.

Introduction: Water, energy, and the environment are three important elements of sustainable development. Production of potable water using desalination technologies powered by renewable energy systems could help solve water scarcity in remote areas with shortages of water or conventional energy sources, or in large cities with air pollution. Hybridization of solar and wind could increase the sustainability and availability of renewable energy sources and reduce energy costs. Additionally, hybridization of reverse osmosis (RO) and MSF could increase efficiency and desalinated water quality and decrease desalinated water cost. Materials and Methods: The research method in this paper is based on modeling, computer simulation, and optimization with MATLAB software, and manufacturing and evaluating the plant at the Tarbiat Modares University Renewable Energy Laboratory. Results: The process of manufacturing the MSF system, solar panel structure, and wind turbine was explained and modeling and optimization results were presented. Testing results of the plant were mentioned, as were the produced power of wind turbine simulated and plant performance evaluated under the environmental conditions of the Tehran region. The rate of fresh water production under changing feed water salinity was evaluated and the real costs of fresh water produced ($/m3) were estimated. At the end of this section, model results and test results were compared. Conclusion: Hybridization of RO and MSF systems with wind and solar energy resources led to increased system reliability and flexibility and higher produced drinking water quality. The desalinated water cost was 1.35 $/m3 in theory and 1.5 $/m3 for actual conditions. Hybridization of wind, solar, RO, and MSF showed proved the best choices to minimize water cost compared to fossil fuel RO or MSF, wind RO, wind MSF, solar RO, solar MSF, or fossil fuel RO-MSF. Hybridization of RO and MSF would result in better economics and operation characteristics than those corresponding to MSF. Water cost can be reduced by 23 to 26% of that of a sole MSF process and the amount of desalinated water produced by the hybrid RO-MSF system is much greater than that of MSF. A comparison of theory outputs and experimental test results showed very good agreement between measured and model data. The test results of the manufactured hybrid solar-wind RO-MSF justified theory results.

Relevance of research. In order to reduce energy losses, an accurate and timely forecast of the amount of consumed electricity is necessary. Accurate forecasting of electrical loads of industrial enterprises and their divisions (productions, workshops, departments etc.) allows planning of normal operating conditions, concluding contracts for the electricity supply with the electricity supply company under more favorable conditions, and improving the electricity quality, which ultimately affects the final cost of the products produced by an enterprise. So far, more than 150 forecasting methods of electrical loads have been developed. Usually, the most convenient one is selected based on the forecaster experience by creating and analyzing several forecasting models in order to identify the best. Therefore, in order to simplify the forecasting procedure, it is necessary to develop the methodology for forecasting analysis. This methodology should enable canceling forecasting algorithms that will create lower quality forecasts. The main objective is to develop the methodology for making a forecasting analysis of power consumption on the example of a pumping station of an enterprise with a continuous cycle of work to increase the efficiency of energy consumption and implementation of energy-saving measures. Objects of research: the process of forecasting electrical loads of a pumping station of the enterprise with a continuous cycle of work. Methods of research: fundamental principles of the theory of electrical engineering, statistical methods for power consumption forecasting, the method for detecting the trend of radio signals, and fractal analysis of time series. Research results. The methodology for forecasting analysis of power consumption, which makes it possible to apply the most appropriate methods to forecast the operational power consumption, is developed. For the first time, the radio signal trend detection method is applied to identify the trend of electrical loads. The variation ranges of the fractal parameters of time series of electrical loads are established depending on the variation coefficient of the time series for different periods of time. The Brown method of exponential smoothing that is used to forecast the electrical loads, in the case of identifying the smoothing constant α is in the beyond set ( ), is further improved. The regularity of changes in the fractal parameters of time series of power consumption of a pumping station with an increase in the time series duration and their field of application are explained.

Objective: Physical inactivity is linked to chronic illnesses and disabilities among workers, especially those in high demanding jobs like teachers. Despite the global prominence of sedentary behaviour research, studies drawing the relationships between physical inactivity and multimorbidity among working teacher populations in low-and middle-countries remain untapped. This study assessed the sedentariness and health status of primary school teachers in Cape Coast Metropolis in Ghana.
Method: This cross-sectional survey employed 1109 primary school teachers from the Cape Coast Metropolis in the Central Region of Ghana, using convenient sampling method.
Results: Generally, the teachers were highly sedentary and reported poor health status. Other results showed no difference in sedentariness across gender, t (1107) = -0.32, p &gt; .05. However, female teachers suffer more pain and discomfort, [t (1103.51) = - 3.07, p &lt; .05, anxiety and depression, [t (1099.56) = - 2.85, p &lt; .000,)], and poor health status [t (1107) = 2.14, p &lt; .05, than their male counterparts. Also, pain and discomfort, anxiety and depression, health status and years of work significantly predicted sedentariness among the teachers, F (4, 1104) = 5.966, p=.00, R = .145, R2 = .029, adjusted R2 = .018.
Conclusion: The findings suggest that individualized or personalized interventions are urgently needed to promote regular physical activity to improve the health status and reduce associated complications on the health and well-being, especially among the female primary school teachers. Given the health risks of sedentary lifestyle, behavioral interventions at the person-level (i.e., individualized- routine weekly physical activity programmes) and built environmental restructuring (e.g., creation of walkways to encourage regular walking) could be done to physical activity behavior among teachers within the Cape Coast Metropolis, and perhaps beyond.

Published: March 2023

Abstract
Background: The annual incidence of out-of-hospital cardiac arrest (OHCA) Worldwide is around 55 per 100,000 inhabitants, with an average of 8% survival rate at hospital discharge. Immediate bystander cardiopulmonary resuscitation (CPR) and early defibrillation have proven to be one of the main factors associated with improved survival after OHCA. The rate of bystander CPR and the use of automated external defibrillators (AEDs) vary between countries. Throughout the World, various public health policies and strategic initiatives on bystander CPR and AED education and training have been implemented influencing the number of OHCA survivors and their subsequent quality of life. The aim of our study was to explore medical and dental students’ self-reported competence towards basic life support with an automated external defibrillator (BLS/AED) employment in real OHCA situations after standardised CPR education and training in low-income country.
Methods: Final medical and dental students were surveyed after completion of the BLS/AED course by an anonymous questionnaire composed of questions about demographic data, attitudes toward BLS/AED education and training, alongside students' self-reported competence towards BLS/AED employment in real OHCA situations.
Results: Medical and dental students demonstrated a positive attitude towards BLS/AED education and training (P<0.001). However, there was great uncertainty in willingness to perform BLS/AED in real OHCA situations, mainly due to causing potential harm to the victim (P<0.001).
Conclusion: Our study has important implications for the early management of OHCA in low-income country. Although our students exhibited a positive attitude towards BLS/AED education and training, still the majority of students feel less confident in applying BLS/AED in real-life situations, due to the potential to cause greater harm. For the prospective standardised CPR education and training programs we strongly suggest further demystification of potential harms complementary to BLS/AED performance to advance OHCA survivor rates and their subsequent quality of life.

Abstract
Introduction: While lifelong and strict adherence to gluten-free diet (GFD) is essential for the successful treatment of celiac disease (CeD), only 30-50% of patients are able to maintain a good adherence to GFD. We determined factors influencing the adherence to GFD at various ecological levels including intra-personal, inter-personal, organizational, community and system-based levels in adult patients with CeD.
Methods: A questionnaire to assess the adherence was developed and it was administered in the CeD clinic to patients with CeD on GFD for >1 year. Adherence to GFD was assessed in a subset of patients (n=320) using Celiac Disease Adherence Test (CDAT).
Results: Overall, 978 patients [median age: 29 years; females: 592] with CeD on GFD were recruited. They reported many barriers to adherence to GFD including intra-personal barriers such as lack of knowledge about GFD (19%), inadequate financial resources (27.2%) and lack of self-motivation/confidence (55.3%); inter-personal barriers such as intake of gluten-containing food upon forceful insistence of friends/family (23.4%); organizational barriers such as high cost (70.8%) and non-availability of GF-food products (48.6%); community-based barriers like consumption of gluten-containing food at religious occasions/festivals (11.1%) and social occasions (27.2%); and system-based barriers such as non-referral to dietitian for counseling (21.9%). As per CDAT, 204 (63.7%), 73(22.8%) and 43(13.4%) patients had good, average, and poor adherence to GFD, respectively.
Conclusions: Non-referral to a dietitian for counseling, irregular follow-up visits, unavailability of flour mill, non-supportive family/friends, high cost and limited availability of GF-food are the most common barriers to adherence to GFD. There is a need to create infrastructure and develop strategies to overcome these diverse barriers at various levels of ecosystem and thereby facilitate better adherence to GFD.

Abstract
Background: A minority of American youth meet CDC physical activity (PA) recommendations; children in the Bronx face additional structural barriers to engaging in PA. The B'N Fit Power expansion draws on pilot programming to increase the proportion of middle school students who engage in one hour of daily PA. The COVID-19 pandemic presented additional obstacles, including increased food insecurity and suspension of organized PA programming. This research aimed to evaluate differences in baseline target behavior attainment before and after the start of the COVID-19 pandemic to inform future programming to help children reduce their risk of obesity.
Methods: Afterschool program leaders at three Bronx public schools collected demographic and target behavior data at baseline and attendance data throughout the school year.
Results: During the 2016-2017 and 2017-2018 school years, 76 students enrolled and completed one year of programming, which was administered at a single site (61% Hispanic, 46% female). Of these, 76 (100%) completed a baseline target behaviors questionnaire. During the 2021-2022 school year, 417 students enrolled and completed one year of programming at one of the three sites (70% Hispanic, 48% female). 89 (21%) completed a baseline target behaviors questionnaire. Participants surveyed after the start of the COVID-19 pandemic reported drinking more sugar-sweetened beverages (Median=3 daily, IQR 2-5), sleeping less (Median=8 hours daily, IQR 6-9 hours), and consuming fast food more frequently (Median=1 time weekly, IQR 0 times weekly-2 to 3 times weekly) than those surveyed prior to the start of the pandemic. The number of PA hours completed each week trended toward significant decline (Median=3, IQR 2-5, p=0.09) in students tracked after the start of the pandemic .
Conclusions: The attainment of several target behaviors among school children linked to the reduction of childhood obesity declined during the COVID-19 pandemic. These findings can be applied to enhancing existing real-world afterschool PA programming.

Published: March 2023

Abstract
Background and Aims: Despite a huge body of evidence on the link between dietary intake and pattern of sleeping, the findings are controversial. The current study aimed to summarize earlier findings on the association between adherence to Mediterranean diet and pattern of sleeping.
Methods: We systematically searched in PubMed, Scopus and Google Scholar to find out relevant publications appeared up to February 2023. No restrictions on language and time of publication were applied. Duplicate citations were removed. Observational studies assessing the association between adherence to MD and sleep pattern were included in this systematic review.
Results: A total of 12 observational studies in which consumption of Mediterranean dietary pattern was the main exposure and one of sleep disorders was an outcome variable were included. Out of these studies, two were cohort studies and ten others had a cross-sectional design. Included studies consisted of 13,396 participants. Usual dietary intakes was assessed using validated Food Frequency Questionnaire, and diet history. The remaining three studies did not report methods of measuring habitual dietary intakes. Adherence to MD was evaluated by KIDMED questionnaire, PREMED, alternate Mediterranean (aMed) questionnaire, MEDAS questionnaire, MedDietScore, MEDI-LITE score, modified Mediterranean Diet Score (mMDS) and Mediterranean food pattern (MFP). Pattern of sleeping was examined as sleep quality, sleep duration, sleep latency, sleep efficacy, sleepiness, sleep disturbance, taking a nap and some other sleep disorders.
Conclusion: In conclusion, findings of published studies highlight the importance of consumption of Mediterranean diet for better sleep quality.
