Number Of Births

<p>The theories developed to explain the beginning of labor are usually considered outside the possible exogenous influence. In the literature, there are prerequisites for the study of the impact of meteorological factors on the initiation of delivery. The paper presents data on the dependence of the birth rate on meteorological environmental factors (atmospheric pressure, its gradient, temperature and humidity, wind speed) in a temperate continental climate of Western Siberia (Barnaul). The data recorded during 1998 (1,154 data) and within the climatic seasons are analyzed. For the purpose of verification of the received regularities, the repeated analysis is carried out on the material of data of 2014 (2145 data) on the basis that unlike a number of years which divided 1998 and 2014, environmental factors were the closest and typical for Barnaul climate. Conclusions were made on the results of the two replications based on these 1998 and 2014. With the help of dispersion analysis, it is shown that the key factor affecting the rate of delivery is the daily drop in atmospheric pressure in the direction of its reduction. Peculiarities of influence of meteorological factors on the frequency of births in different climatic seasons of the year. In particular, it was found that in the winter climatic period the number of births is most affected by meteorological factors, which include air temperature, atmospheric pressure, baric trend, air humidity. Possible mechanisms of observed phenomena are analyzed. It is assumed that one of the possible mechanisms of influence on the initiation of labor can be stressful corticotrophin-releasing secretion of hypothalamic factors, which, connected to the placental hormone, which is considered the "molecular clock" of pregnancy, its concentration increases and exceeds a certain threshold acts as a trigger to run the process of delivery ( Stefano et al., 2015). The second, the most probable factor influencing childbirth may be short-term changes in atmospheric pressure: it is possible the direct mechanical action of external barometric shifts on the volume of internal closed air-containing cavities, in particular, gas bubbles in the intestine, the swelling of which, when the atmospheric pressure decreases, can increase the pressure in the fetal bubble.</p>

The Relationship

Introduction. The impact of weather factors on the occurrence of exacerbations of diseases in meteodependent people is currently one of the actively studied problems of medicine. The aim of the study was to identify the relationship between exacerbations of diseases of the cardiovascular system with the meteorological situation to substantiate the need for preventive and informational work with meteodependent patients. Material and research methods. The study used daily data on the number of patients with cardiovascular diseases seeking medical care at Voronezh City Polyclinic No. 18 and daily information on weather conditions for 2018. The ratio of the average number of cases of medical assistance requests on days unfavourable for meteorological factors to the average number of cases of medical assistance requests per day during the year was calculated. Using software (Statistica Base V6.1), a correlation analysis of the relationship between the number of medical requests and meteorological factors was carried out. Results. It has been established that the appealability of patients with cardiovascular diseases for medical care on days unfavourable for meteorological factors is 1.1-2.0 times higher than the average annual indicator. The most informative characteristic of the six meteorological indicators taken into account in the study (average daily, minimum, maximum ambient air temperature; temperature drops by more than eight °C per day; atmospheric pressure; atmospheric pressure drops by 12 mm Hg per day or more) is a sharp drop in atmospheric pressure during the day, with which statistically significant (p <0.05) correlates the number of cases of patients with cardiovascular diseases seeking medical help. Conclusion. In medical institutions providing primary health care, it is advisable to single out separate groups of patients with meteorological dependence for dynamic observation and conduct information work with them to mitigate the severity of the course of diseases of the cardiovascular system on days unfavourable according to meteorological indicators.

The Impact

The emergence of a novel human coronavirus, SARS-CoV-2, has become a global health concern causing severe respiratory tract infections in humans. Human-to-human transmissions have been described with incubation times between 2-10 days, facilitating its airborne spread via droplets. The impact of environmental factors on the coronavirus disease 2019 (COVID-19) outbreak is under consideration. We therefore reviewed the literature on all available information about the impact of environmental factors on human coronaviruses. Temperature, humidity and other environmental factors have been recorded as environmental drivers of the COVID-19 outbreak in China and in other countries. Higher temperatures might be positive to decrease the COVID-19 incidence. In our review, the analysis of 23 studies show evidence that high temperature and high humidity reduce the COVID-19 transmission. However, further studies concerning other environmental (namely meteorological) factors role should be conducted in order to further prove this correlation. As no specific therapies are available for SARS-CoV-2, early containment and prevention of further spread will be crucial to stop the ongoing outbreak and to control this novel infectious thread.

Abstract COVID-19 has taken the world by storm, with the majority of nations still being challenged by the novel coronavirus. The present work attempts to evaluate the spread of COVID-19 in India using the Susceptible-Exposed-Infectious-Removed (SEIR) model to establish the impact of socio-behavioural aspects, especially social distancing. The impact of environmental factors like temperature and relative humidity (RH) using statistical methods, including Response Surface Methodology (RSM) and Pearson’s correlation, is also studied on numbers of COVID-19 cases per day. Here we report the resultant changes of lockdowns-unlocks initiated by the Government of India for COVID-19, as against the scenario of total lockdown. The phased unlocks and crowded gatherings result in an increase in the number of cases and stretch the mitigation timeline of COVID-19 spread, delaying the flattening of the curve. The SEIR model predictions have been fairly validated against the actual cases. The daily spread of COVID-19 cases is also fairly correlated with temperature in Indian cities, as supported by well-established causation of the role of higher temperatures in disrupting the lipid layer of coronavirus, but is greatly undermined by the key factor of social distancing and gets confounded with other multiple unknown co-varying environmental factors. However, the analysis couldn’t clearly establish the role of RH in affecting daily COVID-19 cases. Hence, it becomes essential to include environmental parameters into epidemiological models like SEIR and to systematically plan controlled laboratory experiments and modeling studies to draw conclusive inferences, assisting policymakers and stakeholders in formulating comprehensive action plans to alleviate the COVID-19 spread.

The Impact

With the increasing pace of global warming, it is important to understand the role of meteorological factors in influenza virus (IV) epidemics. In this study, we investigated the impact of temperature, UV index, humidity, wind speed, atmospheric pressure, and precipitation on IV activity in Norway, Sweden, Finland, Estonia, Latvia and Lithuania during 2010–2018. Both correlation and machine learning analyses revealed that low temperature and UV indexes were the most predictive meteorological factors for IV epidemics in Northern Europe. Our in vitro experiments confirmed that low temperature and UV radiation preserved IV infectivity. Associations between these meteorological factors and IV activity could improve surveillance and promote development of accurate predictive models for future influenza outbreaks in the region.

We studied the impact of meteorological factors including atmospheric pressure, relative and absolute humidity, air temperature, wind speed, and precipitation quantity on COVID-19 incidence and mortality rates in Moscow during the first wave of the pandemic from 1st April to 25th June 2020 using a correlation analysis. The calculations created new scientific knowledge about the effects of fluctuations in average daily values of weather parameters on the dynamics of the COVID-19 pandemic and demonstrated their statistical significance. We established that meteorological factors had a greater influence on the incidence than on mortality from the novel coronavirus disease. Atmospheric pressure and wind speed had the strongest effect on incidence and mortality rates of Muscovites while air temperature and precipitation quantity demonstrated the least impact. Correlation coefficients of 0.50–0.70 enabled us to assert that the meteorological factors start influencing the incidence and mortality 6 to 8 weeks before the disease onset. Based on empirical data, we also estimated that the most likely period between the disease onset and death of COVID-19 patients ranged from 8.63 to 22.13 days, the average being 12.63 days. The resulting statistical patterns demonstrate high convergence with actual data and international experience and allow determination of the degree of influence of meteorological conditions on the development of the COVID-19 pandemic in different periods and prognosis of the worst scenarios in the city enabling appropriate and timely preventive measures.

The Impact

The analysis of competition policy under economic crisis is motivated by the fact that competition is a key factor for the level of productivity. The latter, in its turn, influences the scope and length of economic recession. In many Russian markets buyers' gains decline because of the weakness of competition, since suppliers are reluctant to cut prices in spite of the decreasing demand. Data on prices in Russia and abroad in the second half of 2008 show asymmetric price rigidity. At least two questions are important under economic crisis: the 'division of labor' between pro-active and protective tools of competition policy and the impact of anti-crisis policy on competition. Protective competition policy is insufficient in transition economy, especially in the days of crisis it should be supplemented with the well-designed industrial policy measures which do not contradict the goals of competition. The preferable tools of anti-crisis policy are also those that do not restrain competition.

Optimal Conditions

The surfaces of building materials of hydrotechnical constructions undergo the process of algae biofouling. The degree of damage depends on the environmental factors that are affect-ed by the level of anthropogenic load areas. Modeling the biofouling process of concrete with algae under laboratory conditions has allowed determining their impact on the building ma-terial, accompanied by changes in chemical and mineralogical composition of the surface of products. The microscopic examination of sample’s surfaces and evaluation of the effective-ness of various ions leaching from building materials shows the results of "algal attack" relat-ed to the acceleration of biodegradation of materials under the influence of aggressive meta-bolic products, mechanical action neoplasms, creating optimal conditions for the development of subsequent aerobic microbial decomposers. To clarify the nature of chemical processes in the system “algocenosis – concrete” the changes of chemical and phase (mineralogical) com-position of the surface layer of concrete sample were studied. The effect that algae produce on hydraulic engineering constructions is due to the fact that these organisms, belonging to phototrophs and standing at the beginning of the food chain, initiate new microbial growth.
