Background. Large-scale construction of industrial and transport facilities is underway in the Far North of Russia. The process involves more than 10,000 shift workers, and there was a Covid19 outbreak in this population. In order to contain the outbreak and prevent the spread of infection in this area the Russian Emergencies Ministry deployed an airmobile hospital.Purpose. The purpose is to present an experience of work with the mobile CT scanner as part of an airmobile field hospital deployed in the Far North of Russia to combat the Covid-19 outbreak.Materials and methods. On April 6, 2020, the construction site reported a “zero patient” who sought medical aid; the PCR test showed positive results of coronavirus. In the first half of April, over 300 rotation employees applied for medical care, most of them had a positive PCR test. On April 11, a state of emergency was declared in the construction site and, on April 17, 2020, airmobile hospital started operations. Its mission lasted 54 days. The mobile CT scanner (Brightspeed Elite Mobile, GE) was transported by land. The field hospital closely cooperated with the nearest medical institutions and the regional clinical hospital.Results. During its work the airmobile hospital examined 1,678 rotational workers and 408 employees of the Ministry of Emergency Situations of the Murmansk region, with 2,086 CT scans performed. The average age of the patients was 37.8 years, men predominated. In 91.2% of patients, fever was the first symptom of the disease. Blood saturation results ranged from 92% to 99%. The degree of lung involvement ranged from CT 0 to CT 4. During the work of the airmobile hospital, COVID-19 was diagnosed in 500 people, including 328 cases of mild form, 98 – moderate, 74 – severe, no mortalities.Conclusion. A positive experience of application of the mobile CT scanner as part of the AMH field hospital in unfavorable epidemiological conditions of the Far North of the Russian Federation was obtained. CT plays a key role in early detection of infection, differential diagnosis, and identification of complications. Determination of the severity of the disease based on CT data is crucial for patient routing.

Relevance. Based on the appeal of the Governor of the Murmansk region to the Operational Headquarters on preventing import and spread of a new coronavirus infection in Russia due to the aggravation of the epidemiological situation and in order to localize the spread of COVID-19, the Russian Emercom allocated forces and capabilities, including an airmobile hospital (AMH) and a temporary accommodation center, in the region. AMH was deployed at the industrial site of the Center for the construction of large-scale offshore facilities of NOVATEK-Murmansk LLC and subcontractors in Belokamenka village, where more than 10 thousand people worked and lived on a rotational basis.Intention. Summarize and analyze the experience of the AMH of Emercom of Russia under field conditions of an outbreak of the new coronavirus infection.Methodology. Daily reports on the activities of Emercom of Russia AMH were analyzed for the period from April 17, 2020 to June 12, 2020.Results and Discussion. Field camp deployment and functioning of Emercom of Russia AMH integrated into a regional medical and preventive institution are described. The data on admitted patients, scope and types of diagnostic tests are presented. It is shown that AMH as a separate outpatient diagnostic department of the Kolsky Central District Hospital should provide special and sanitary treatment, patient referrals and an algorithm of personnel activities, and also comply with antiepidemic measures. During the period of AMH activities in the field, 1678 shift workers got medical advice, 3086 diagnostic studies were carried out for shift workers and employees of the Emercom of Russia. COVID-19 was detected in 500 persons, including 328 cases of mild disease, 98 cases of moderate severity, and 74 severe cases, without case fatalities. The outbreak and spread of the new coronavirus (COVID-19) infection as an emergency in the subject of Russia and at the large industrial and construction site were brought under control.Conclusion. This experience will help improve the activities of the Emercom of Russia AMH under field conditions.

Background: Chest computed tomography (CT) is a recommended screening and assessment tool for patients with suspected coronavirus disease (COVID-19). However, CT units are currently not available in many temporary hospitals and centralized isolation places. Objectives: To delineate the workflow of mobile CT unit and evaluate its role in screening for COVID-19 infection in temporary hospitals and centralized isolation locations. Patients and Methods: Two hundred and twenty-three patients under medical observation in temporary centralized isolation were enrolled in this study. All patients underwent reverse-transcription polymerase chain reaction (RT-PCR) testing and mobile CT chest examinations. Communication, storage, and browsing of CT data were performed with 4G and cloud technology. Image quality and radiation dose were evaluated and compared with a commercial conventional 64-row CT scanner. Additionally, the sensitivity of initial chest CT and the initial RT-PCR for COVID-19 were compared. Results: CT examination of 223 patients was completed within 19 work hours. Communication, storage, and browsing of CT data via 4G and cloud technology were seamless. There were no significant differences in subjective image quality scores between groups (P > 0.05). COVID-19 pneumonia was eventually confirmed in 49 patients (21.97%). The sensitivity of initial chest CT was greater than that of the initial RT-PCR (85.71% and 67.35%, respectively) (P < 0.05). Conclusion: Screening suspected patients for COVID-19 by mobile CT in temporary hospitals and isolation points is a simple, efficient, and highly sensitive technique for early diagnosis and control of COVID-19.

AbstractThis paper investigates the consequences for inter-group conflicts of terrorist attacks. I study the 2015 Baga massacre, a large scale attack conducted by Boko Haram at the far North-East state of Borno, Nigeria, as a quasi-natural experiment and examine a set of attitudes in the aftermath of the event of Christians and Muslims throughout the country. Comparing individuals, outside the region of Borno, interviewed by Afrobarometer immediately after the massacre and those interviewed the days before within same regions and holding fixed a number of individual characteristics, I document that the informational exposure to the event rendered Christians less amiable to neighboring Muslims and Muslims less likely to recognize the legitimacy of the state. Nonetheless, Muslims increased their view of the elections as a device to remove leaders in office, event that took place 2 months later with the election of the challenger, Muhammadu Buhari. My findings indicate that terrorist attacks may generate a relevant and heterogeneous backlash across ethnic groups.

<p>For the coming ten years, the heart of Europe will turn into a gigantic construction site for works on one of the largest hubs of the continent: Antwerp. The Oosterweel Link is the project whereby the motorway ring around Antwerp is undergoing a metamorphosis to reinvigorate traffic flow and add living space to the City. The project had come to a standstill for several years as a result of protests by assertive citizens, but was given a second lease of life following a large-scale participation project.</p><p>To ensure its successful completion, unparalleled efforts are being made in the field and in the area of digitization. It is therefore with good reason that in Belgium the project is referred to as “the construction site of the century”.</p>

Computational simulation is a powerful tool for performance evaluation of computational systems. It is useful to make capacity planning of data center clusters, to obtain profiling reports of software applications and to detect bottlenecks. It has been used in different research areas like large scale Web search engines, natural disaster evacuations, computational biology, human behavior and tendency, among many others. However, properly tuning the parameters of the simulators, defining the scenarios to be simulated and collecting the data traces is not an easy task. It is an incremental process which requires constantly comparing the estimated metrics and the flow of simulated actions against real data. In this work, we present an experimental framework designed for the development of large scale simulations of two applications used upon the occurrence of a natural disaster strikes. The first one is a social application aimed to register volunteers and manage emergency campaigns and tasks. The second one is a benchmark application a data repository named MongoDB. The applications are deployed in a distributed platform which combines different technologies like a Proxy, a Containers Orchestrator, Containers and a NoSQL Database. We simulate both applications and the architecture platform. We validate our simulators using real traces collected during simulacrums of emergency situations.

<p>In June 2013, three consortia were awarded the three construction packages that constitute the whole Riyadh Metro Project in Saudi Arabia for a total of 6 lines and 180 kilometres.</p><p>International Bridge Technologies was in charge, as a subconsultant of Idom, of the complete structural scope of services for the 25.6 km of elevated viaduct that Riyadh Metro Package 2 comprises (Line 3, around 41.6 km, out of which 25.6 km are elevated). This scope consisted of the full range of services from conceptual tender design to final detailed design, including shop drawings production, construction engineering and construction site support.</p><p>The Line 3 elevated viaduct consists of a three-cells precast segmental box-girder with typical simply-supported spans of 37 m and special continuous spans of 50 m. Six long span structures with spans varying from 60 m to 95 m were required for the special crossings over existing interchanges. Typical and continuous spans are erected span-by-span with an overhead truss while long spans are erected in balanced cantilever with cranes on the ground or lifting frames on the deck.</p><p>The present paper is centred on the design of the elevated viaduct and presents the different structures with key features and how they were constructed to permit large scale standardisation and speed of construction. Some key design aspects are developed, in particular the design approach for the 3-cells box-girder as the most effective solution to satisfy the imposed aesthetic criteria. This paper also exposes the design approach adopted to produce a “design-for-demand” by relying as much as practically possible on a realistic modelling of the alignment and by limiting parametric design. This allowed for an optimisation of material quantities.</p>

The Zhdanovskoe copper-nickel sulfide ores deposit is located in the north-west of the Murmansk region and is a mineral raw material source for JSC «Kola MMC». The main mining method used is sublevel caving. In some areas, due to the complex shape of the ore bodies, the open stoping mining method is used which requires determining stable parameters of stopes and pillars. It is necessary to study the stress-strain state of the deposit to ensure safe mining conditions. One of the possible solutions is the modeling of the stress-strain state of rock mass using the finite element method, for example, CAE Fidesys, which is FEMbased software. The use of CAE Fidesys for solving geomechanics tasks allows creating models of individual excavation units to determine the stability of stopes and pillars, and large-scale models that include several ore bodies and areas of the host rock mass. The article considers solutions of both types of geomechanic tasks using CAE Fidesys for conditions of the Zhdanovskoe deposit.

Real time collaboration solutions are critical during a large scale emergency situation and necessitate the coordination of multiple disparate groups. Collaborative technologies may be valuable in the planning and execution of disaster preparedness and response. Yet, research suggests that specific collaborative technologies, such as group decision support systems, are not often leveraged for decision-making during real time emergency situations in the United States. In this chapter, we propose a theoretical model of the impact of disaster immediacy and collaboration systems on group processes and outcomes. Using a 3D model of the dimensions of space, time, and situation, we explore media richness and group polarization within the context of collaboration technologies and disaster situations. We also present the next generation of collaboration technology extensions in order to address the need for more contemporary decisional settings. This set of principles and theories suggest how collaborative technologies may be positioned to better manage future disasters.

Electronic Health Records (EHRs) are becoming the ubiquitous technology for managing patients' records in many countries. They allow for easier transfer and analysis of patient data on a large scale. However, privacy concerns linked to this technology are emerging. Namely, patients rarely fully understand how EHRs are managed. Additionally, the records are not necessarily stored within the organization where the patient is receiving her healthcare. This service may be delegated to a remote provider, and it is not always clear which health-provisioning entities have access to this data. Therefore, in this chapter the authors propose an alternative where users can keep and manage their records in their existing eHealth systems. The approach is user-centric and enables the patients to have better control over their data while still allowing for special measures to be taken in case of emergency situations with the goal of providing the required care to the patient.
