Текущая пандемия COVID-19 показала, что у принимающих решения органов власти отсутствуют инструменты, которые бы позволяли принимать обоснованные решения по введению карантинных мер, проведению/отмене массовых мероприятий в зданиях. Зачастую это приводит к введению либо избыточных (что вызывает ухудшение экономической ситуации), либо недостаточных мер (что приводит к ухудшению эпидемиологической ситуации). В настоящей статье дано описание математической основы и базовых принципов создания программного комплекса для оценивания вероятности заражения вирусной инфекцией, передающейся воздушно-капельным путем, в зданиях с массовым пребыванием людей The current COVID-19 pandemic has shown that decision-making authorities lack tools that would allow them to make informed decisions on the introduction of quarantine measures related to either holdingor canceling mass events in buildings. Often this leads either to the introduction of excessive (which leads to a worsening of the economic situation) or insufficient measures (which leads to a worsening of the epidemiological situation). This article describes the mathematical basic principles aimed at creating a software package for assessing the likelihood of contracting a viral infection transmitted by airborne droplets in massively occupied buildings. Evaluation of the likelihood of COVID-19 infection in public places is possible based on a joint analysis of the results of the people movement simulation, air circulation and the spread of aerosols from a carrier of the infection, taking into account the applied methods of protection (masks, ventilation). It is required to develop methods for assessing the danger of COVID-19 infection from a carrier of the virus and the methods of protection used (masks, ventilation) in specific public places. Simultaneously, the movement of people in accordance with the mode of operation, air movement (including ventilation systems) and the spread of respiratory aerosols needs to be accounted for

The majority of the knowledge and philosophy of African roots find a great discrimination in public places in Brazil, rarely we see schools take in consideration those questions, popular knowledge and ways of living of those who follow those religions of African roots. Take in account that reality and seeking for changing it, the members of Abassá of goddess Òsùn of Idjemim, Paulo Afonso - BA, Bahia took the initiative of producing an animated stop motion movie about the Òrìṣà Òsùn. In this short motion “Òpárà de Òsùn: when everything is born” (2018) we can see the language of animation cinema being used to tell stories of Òrìṣàs like of a way clamouring the religiosity from people from traditional places and also a way of facing religious racism. In this work, we will present the process of production of a short motion, that took in consideration the bio system Caatinga and of the Sao Francisco river as a scenery of some events, staring from the sonorities and images produced by the people in the Terreiro and including the poetic language (could it be sounding and visual or spoken). From those elements, we reflect about the role played by this short movie on the empowerment of children and territorially as didactic and educative space.

<p>Whangarei City has a dying Commercial Centre. This has resulted from population shifts that have occurred over time. Significant issues have driven movement of people toward much larger cities (seeking better economic, cultural and social outcomes) and more spacious urban fringes (seeking improved environmental outcomes). The Whangarei CBD incorporates both the dying Commercial Centre and a thriving Town Basin which is the centre for Arts and Recreation within the city. The two areas are a juxtaposition. The investigation reveals reasons why two such contrasting areas exist and defines a design solution that seeks to resolve this and leverages the success of the Town Basin to revive the Commercial Centre. The aim of this thesis is to investigate ways that architecture can be used to invigorate Whangarei’s dying Commercial Centre by creating a place of activity, engagement and informal learning and by re-establishing the important connection Whangarei has with its river as well as other positives within the city.   Thesis objectives:  • Identify the reasons for the decline of the Commercial Centre and the success of the Town Basin and how a connection can be established between the two.  • Establish a beating heart within the dying Commercial Centre and provide a life source in the form of people movement into the centre from all parts of the city.  • Provide dynamic spaces which encourage informal learning, social interaction, playfulness and creativity that will engage the people of Whangarei including youth and children.  • Use the natural environment as a means of engaging people of all ages by weaving together water, a restored ecology and architecture.</p>

Economic and social progress in our practice depends upon the sustained interest and the effort of the individual physician. Courage and faith are necessary foundations for action in this critical year of decision, and there is every reason to believe that the new generation of pediatricians has every qualification necessary to continue the quest for better health among children. His adventure in "practical idealism" will not be an easy one. But, fortified by the assurance of his noble heritage of accomplishment and adherence to high standards, he will accept the challenge of the future with a deep sense of responsibility. He will keep faith with those who have gone before, and attempt to retain the confidence and trust of the people as did our fathers, by holding high the banner of service. The price of success in this undertaking involves a determination to reach our objectives regardless of adverse circumstances, concentration on the immediate problems, and by long range plans for fulfilling our obligations to the children of America. Frustration and differences of opinion are inevitable. Changing conditions require flexibility in our adaptation to existing needs. Let us keep our eyes upon the stars, but our feet upon the ground! Our responsibilities are great. The Dean of the School of Medicine at the University of Wisconsin, Dr. William S. Middleton, recently stated the challenge in these words: "Make no small plans; they have no magic to stir man's soul!" Medicine progresses, even in a troubled world. Changes in governments, in laws and controls, have not interfered with this progress. Civilizations of the past have been destroyed by the decay and infamy and greed within their own structure. Let us renew our faith in the simple basic principles, which have characterized the growth and development of the Academy for 22 years.

This chapter tells the story of public speaking in Russia from the imposition of greater restrictions on the public sphere in 1867 through to the eve of Alexander II’s assassination in 1881. It shows that in this period the focus of the Russian public switched from the zemstvo to the courtroom, where a number of high-profile trials took place (and were reported, sometimes in stenographic detail, in the press). The chapter examines the careers and profiles of some of Russia’s leading courtroom orators. It also explores the activities of the Russian socialists (populists), in particular the ‘Going to the People’ movement of 1873–4 and later propaganda efforts in the city and the courtroom. It ends by considering the intensification of public discourse at the end of the 1870s: the Russo-Turkish War saw a surge of patriotic mobilization, but at the same time the populist adoption of terrorism seized public attention.

In public places, the high pedestrian density is one of the direct causes leading to crowding and trample disaster, so it is very necessary to investigate the collective and evacuation characteristics for pedestrian movement. In the occupants’ evacuation process, the people-people interaction and the people-environment interaction are sufficiently considered in this paper, which have been divided into the exit attraction, the repulsion force between people, the friction between people, the repulsion force between human and barrier, and the attraction of surrounding people. Through analyzing the existing models, a new occupant evacuation cellular automata (CA) model based on the social force model is presented, which overcomes the shortage of the high density crowd simulation and combines the advantages that CA has sample rules and faster calculating speed. The simulating result shows a great applicability for evacuation under the high density crowd condition, and the segregation phenomena have also been found in the bidirectional pedestrian flow. Besides these, setting isolated belt near the exit or entrance of underpass not only remarkably decreases the density and the risk of tramper disaster but also increases the evacuation efficiency, so it provides a new idea for infrastructure design about the exits and entrances.

The author describes the preparation and implementation of mass rallies marking the beginning and the end of the Italian invasion of Ethiopia (October 1935 – May 1936) in Italy’s province of Istria. Relying on official regime representation of these events through the writing of the regime-affiliated press and confidential documents, the paper discusses the main organizational and ideological features of the mass rallies, with an emphasis on the manner in which the fascist authorities prepared them and the way they were presented in the press. Throughout the war, mass rallies and events of public ritual contributed to the homogenization of the Italian people, culminating in May 1936 with oceanic assemblies celebrating the victory, and achieving the closest state of unity of the people with the Fascist regime. The country-wide preparations for the “General Assembly of the Forces of the Regime” (Adunata generale delle forze del regime) that marked the beginning of the Italian invasion of Ethiopia were strictly implemented in the Province of Istria in line with the regime’s expectations, and the general population was urged to participate in the mass demonstrations that were believed to have been marking the events of utmost historical significance. The preparations for the Assembly went to the minimal detail, ensuring the participation of every Fascist Party member in the event, while the local daily journal Corriere Istriano motivated the wide masses for this huge event. The Gathering took place in the late afternoon of October 2nd 1935, and both archival documents and the press (focusing on the provincial capital of Pula) emphasized the alleged utmost euphoria and enthusiasm that the event provoked, especially in its dimension of adoration of the Italian leader Benito Mussolini. The gatherings in the so-called “Radiant African May” (Maggio radioso africano) in Istria in 1936 formed an incessant period of mobilization and celebration from May 5th (after the announcement of the capture of the Ethiopian capital Addis Ababa) up to May 10th (after the proclamation of the Empire). In contrast to the initial grand adunata on October 2nd 1935, these gatherings were more hastily prepared but were again ideologically organized and controlled from the government’s centre in Rome. Two main gatherings (May 5th and May 9th) involved the listening to Mussolini’s speeches through speakers put in public places, one of which was the huge Roman-era Amphitheatre in Pula. Besides that, the gatherings followed an already established pattern of forming processions and playing music that captivated the people gathered until early morning hours. The events occurred in the whole Province, and local police were asked to report to the Prefecture in Pula in detail about the gatherings on each locality.

This study has aimed to develop a method for simultaneous extraction and determination by liquid chromatography and mass spectrometry (LC-MS/MS) of glyphosate, aminomethylphosphonic acid (AMPA), shikimic acid, quinic acid, phenylalanine, tyrosine and tryptophan. For the joint analysis of these compounds the best conditions of ionization in mass spectrometry and for chromatographic separation of the compounds were selected. Calibration curves and linearity ranges were also determined for each compound. Different extraction systems of the compounds were tested from plant tissues collected from sugarcane (Saccharum officinarum) and eucalyptus (Eucalyptus urophylla platiphylla) plants two days after the glyphosate application at the dose of 720 g a.e. ha-1. The plant material was dried in a forced air circulation drying oven and in a lyophilizer, and subsequently the extractions with acidified water (pH 2.5), acetonitrile-water (50:50) [v/v] and methanol-water (50:50) [v/v] were tested. To verify the recovery of the compounds in the plant matrix with acidified water as an extracting solution, the samples were fortified with a solution containing the mixture of the different analytical standards present so that this one presented the same levels of 50 and 100 μg L-1 of each compound. All experiments were conducted with three replicates. The analytical method developed was efficient for compounds quantifications. The extraction from the samples dried in an oven and using acidified water allowed better extraction levels for all compounds. The recovery levels of the compounds in the fortified samples with known amounts of each compound for both plants samples were rather satisfactory.

SmartCoat is a novel technology with titanium dioxide (TiO2) nanoparticles, isopropyl alcohol, and distilled water as the active ingredients. TiO2, along with water and oxygen, generates highly reactive OH radicals that can neutralize bacteria and other microorganisms and remove volatile organic compounds (VOCs). Smart coat requires air circulation and a light source for its catalytic activity. The efficacy of TiO2 in industrial setups and dental devices has been documented. The present study aimed to evaluate the efficacy of TiO2 in preventing microbial growth in an operating theater (OT) where maximum sterility is desired to prevent sepsis and nosocomial infections. Among the four operating theaters, two were selected. Periodic swab samples taken over a period of nine months from OT 3 (Smart coated) and OT 4 (Control) showed minimal variations in terms of microbial growth in the processed swabs. The findings were statistically analyzed using a paired-sample t-test. The computed value of ‘t’ i.e., 2.084 was lower than the critical value of 3.18 at 3 deg of freedom (df) and hence was not significant. The null hypothesis cannot be rejected (p=0.129>0.05) at the 5% level of significance. SmartCoat with TiO2 was not effective in preventing microbial growth on biomedical devices in the OT. The product may not be suitable for operating theaters unless it is supplemented by other sterilization procedures. However, it can be used in other healthcare settings and in public places.
