There is a current pandemic of a new type of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The number of confirmed infected cases has been rapidly increasing. This paper analyzes the characteristics of SARS-CoV-2 in comparison with Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), Middle East Respiratory Syndrome Coronavirus (MERS-CoV) and influenza. COVID-19 is similar to the diseases caused by SARS-CoV and MERS-CoV virologically and etiologically, but closer to influenza in epidemiology and virulence. The comparison provides a new perspective for the future of the disease control, and offers some ideas in the prevention and control management strategy. The large number of infectious people from the origin, and the highly infectious and occult nature have been two major problems, making the virus difficult to eradicate. We thus need to contemplate the possibility of long-term co-existence with COVID-19.

Background: There is a current worldwide outbreak of a new type of coronavirus COVID-19. The number of confirmed infected cases is rapidly increasing. Method: This paper analyzes the characteristics of COVID-19 in comparison with Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), Middle East Respiratory Syndrome Coronavirus (MERS-CoV) and influenza. Diagnostic data for foreign citizens evacuated from Wuhan were collected and compiled. Current prevention and control strategies have been analyzed. Results: COVID-19 is similar to SARS-CoV and MERS-CoV virologically and etiologically, but similar to influenza in epidemiology and virulence. The prevalence rate in Wuhan was inferred to be close to 1%. The comparison provides a new perspective for the future of the disease, and offers some advice in the prevention and control management strategy. Conclusion: The large number of patients and the strong occult nature are two big problems, making the virus difficult to eradicate. We need to contemplate the possibility of long-term co-existence with COVID-19.

The article is devoted to major events in the history of the post-Soviet economy, their influence on forming and development of modern Russia. The author considers stages of restructuring, market reforms, transformational crisis, and recovery growth (1999-2011), as well as a current period which started in2011 and is experiencing serious problems. The present situation is analyzed, four possible scenarios are put forward for Russia: “inertia”, “mobilization”, “decisive leap”, “gradual democratic development”. More than 30 experts were questioned in the process of working out the scenarios.

A new type of composite voided slab, the TUBEDECK (TD), which utilizes the structural function of profiled steel decks, has recently been proposed. Previous studies have confirmed that the flexural strength of TD slabs can be calculated based on the full composite contribution of the steel deck, but for long-span flexural members, the deflection serviceability requirement is often dominant. Herein, we derived a novel deflection prediction approach using the results of flexural tests on slab specimens, focusing on TD slabs. First, deflection prediction based on modifications of the current code was proposed. Results revealed that TD slabs exhibited smaller long-term deflections and at least 10% longer maximum span lengths than solid slabs, indicating their greater efficiency. Second, a novel rational method was derived for predicting deflections without computing the effective moment of inertia. The ultimate deflections predicted by the proposed method correlated closely with the deflection under maximum bending moments. To calculate immediate deflections, variation functions for the concrete strain at the extreme compression fiber and neutral axis depth were assumed with predictions in good agreement with experiments. The proposed procedure has important implications in highlighting a new perspective on the deflection prediction of reinforced concrete and composite flexural members.

The publication includes V.Ya. Bryusov’s letters to his fiancée I.M. Runt (1876 –1965) from June 9 to September 9, 1897. 11 correspondences, including the final telegram sent from Kursk, were written and sent from Aachen (Germany), Moscow and several Ukrainian localities. The letter 10 is accompanied by the full text of I.M. Runt’s only surviving letter to Bryusov, sent from Moscow to the village of Bolshye Sorochintsy and received by the poet a few months later at home. The relationship between the young people before the wedding were complicated. While the poet was preparing for the wedding in Moscow, he summed up the past contacts with “mes amantes”, and his state of mind was painful. Shortly before meeting his future wife, Bryusov broke up with the former governess of his family E.I. Pavlovskaya, who was terminally ill. A few days before the wedding he decided to go to say goodbye to Pavlovskaya to her homeland, Ukraine. In his letters to the future wife the poet tried to smooth out the tension of the situation, perhaps anticipating that he would be bounded with I.M. Runt 30 Литературный факт. 2021. № 2 (20) by a long-term relationship, where life and literature are closely interconnected. The letters are published for the first time.

Successful long-term plans for gardens require creativity and objectivity and need to include the insight of the horticultural teams caring for them. Garden plans take different forms and there are rival schools of thought about the merits of using external consultants or authoring exclusively in house. This essay makes the case for a ‘third way’, blending the skills of internal and external teams, and shows how the past can inspire the future.

We live in an age characterized by increasing environmental, social, economic, and political uncertainty. Human societies face significant challenges, ranging from climate change to food security, biodiversity declines and extinction, and political instability. In response, scientists, policy makers, and the general public are seeking new interdisciplinary or transdisciplinary approaches to evaluate and identify meaningful solutions to these global challenges. Underrecognized among these challenges is the disappearing record of past environmental change, which can be key to surviving the future. Historical sciences such as archaeology access the past to provide long-term perspectives on past human ecodynamics: the interaction between human social and cultural systems and climate and environment. Such studies shed light on how we arrived at the present day and help us search for sustainable trajectories toward the future. Here, we highlight contributions by archaeology—the study of the human past—to interdisciplinary research programs designed to evaluate current social and environmental challenges and contribute to solutions for the future. The past is a multimillennial experiment in human ecodynamics, and, together with our transdisciplinary colleagues, archaeology is well positioned to uncover the lessons of that experiment.

The end of the story is all you care about. So, let’s get that out of the way first. Penelope Jane was born on March 23rd. She was healthy. The trauma of that day still resonates within my body, called into being through subsequent visits to the hospital and a review of my own medical records from that day. A life-threatening fever and 9 hours of pushing led to a powerfully negative birth experience, one that I am consistently told to just forget. After she had a weeklong stay in the neonatal intensive care unit (NICU), I have a healthy daughter. In this article, I use auto/archeology as a tool to examine my own medical records and the affective traces of my experience in the hospital to call into question Halberstam’s advocacy of forgetting as queer resistance to dominant cultural logics. While Halberstam explains that “forgetting allows for a release from the weight of the past and the menace of the future” I hold tightly to my memories of that day. This article marks the disconnects between an advocacy of forgetting and my own failure of childbirth and offers a new perspective that embraces the queer potentiality of remembering trauma.

In this paper the impact of adopting the euro in Croatia is analysed using experiences of other countries which have passed through this process in the last decade and which are comparable with Croatia in many aspects. The process of adopting a currency different from the one that has been used for more than twenty years presents a very important economic question for each country. In this period preceding to adopting the euro, there is an opportunity to analyse this process in the countries which went through it in the past. The result of this paper shows the impacts of adopting the euro in the European countries. The selected countries, which are adequate for analysing the effects of adopting the euro, are: Portugal, Ireland, Greece, Spain, Slovenia, Slovakia, Estonia, Lithuania and Latvia. These countries have been selected for different reasons. The majority of these countries have some similarities with Croatia, which are shown in this paper via relevant economic indicators. These results are significant for Croatia and show a positive influence on the Croatian market on a long-term basis. This paper is relevant and has a practical basis both for Croatia and other countries which will go through this process in the future.

On 1 July 1981 the Chinese Communist Party celebrated the sixtieth anniversary of its foundation. To mark this occasion, the Party itself issued a statement summing up the experience of recent decades. It seems an appropriate time for outsiders as well to look back over the history of the past 60 years, in the hope of grasping long-term tendencies which may continue to influence events in the future.

The article describes the development of Czech policy after 1989 and the controversies it caused. It first looks at the ambiguous nature of the communist welfare state and then proceeds to outline the theoretical alternatives. After early and energetic changes in the system, stagnation set in around the mid-1990s. Despite some problems, the current performance of the system is satisfactory, but its outlook in terms of long-term efficiency is unsatisfactory, as it will generate a rising debt into the future. In particular, the disadvantaged situation for families, the insufficient work motivation, and the frozen pension system are all causes for concern. The political shift to the right after 2006 ushered in reform measures and new reform plans. While reforms are necessary, their feasibility is uncertain owing to the fragility of the Czech political scene.
