Background Estimating the cumulative prevalence of SARS-COV-2 will help to understand the epidemic, contagion, and immunity to COVID-19 in vulnerable populations. The objective is to determine the extent of infection in the general population and the cumulative incidence by age group. Methods It was carried out with a longitudinal analytical study, in the population of the Lambayeque region, located in the north of Peru. The selection was carried out in multistages (districts, area, household, and finally choosing the interviewee within the house). Seroprevalence was estimated as a positive result of the rapid test whether it was positive IgM or positive IgG. An adjustment was made for the sampling weights used. Results The seroprevalence found in the region was 29.5%. Young people between 21 and 50 years old presented the highest seroprevalence frequencies. A total of 25.4% were asymptomatic. The most frequent complaint was dysgeusia and dysosmia (85.3% and 83.6%). Dysosmia (PR = 1.69), chest pain (PR = 1.49), back pain (PR = 1.45), cough (PR = 1.44), fever (PR = 1.41), general malaise (PR = 1.27) were associated factors with the higher the frequency of seropositivity for SARS-CoV-2. Reporting of complete isolation at home decreased the frequency of positivity (PR = 0.80), however, reporting having ARI contact (PR = 1.60), having contact with a confirmed case (PR = 1.51), and going to market (PR = 1.26) increased the frequency of positivity for SARS-CoV-2. Conclusion These results suggest that Lambayeque is the region with the highest seroprevalence in the world, well above Spain, the United States and similar to a study in India.

<p>The regional and global precipitation pattern is highly modulated by the influence of El Niño Southern Oscillation (ENSO), which is considered the most important mode of climate variability on the planet. In this study was investigated the asymmetry of the continental precipitation anomalies during El Niño and La Niña. To do it, a Lagrangian approach already validated was used to determine the proportion of the total Lagrangian precipitation that is of oceanic and terrestrial origin. During both, El Niño and La Niña, the Lagrangian precipitation in regions such as the northeast of South America, the east and west coast of North America, Europe, the south of West Africa, Southeast Asia, and Oceania is generally determined by the oceanic component of the precipitation, while that from terrestrial origin provides a major percentage of the average Lagrangian precipitation towards the interior of the continents. The role of the moisture contribution to precipitation from terrestrial and oceanic origin was evaluated in regions with statistically significant precipitation anomalies during El Niño and La Niña. Two-phase asymmetric behavior of the precipitation was found in regions such the northeast of South America, South Africa, the north of Mexico, and southeast of the United States, etc. principally for December-January-February and June-July-August. For some of these regions was also calculated the anomalies of the precipitation from other datasets to confirm the changes. Besides, for these regions was calculated the anomaly of the Lagrangian precipitation, which agrees in all the cases with the precipitation change. For these regions, it was determined which component of the Lagrangian precipitation, whether oceanic or terrestrial, controlled the precipitation anomalies. A schematic figure represents the extent of the most important seasonal oceanic and terrestrial sources for each subregion during El Niño and La Niña.</p>

The article investigates the impact of Great Britain on the evolution of colonialism in the late ХІХ and early ХХ centuries. It is analyzed the sources and scientific literature on the policy of the United Kingdom in the colonial question in the late ХІХ – early ХХ century. The reasons, course and consequences of the intensification of British policy in the colonial problem are described. The process of formation and implementation of London’s initiatives in the colonial question during the period under study is studied. It is considered the position of Great Britain on the transformation of the colonial system in the late XIX – early XX centuries. The resettlement activity of the British and the peculiarities of their mentality, based on the idea of racial superiority and the new national messianism, led to the formation of developed resettlement colonies. The war for the independence of the North American colonies led to the formation of a new state on their territory, and the rest of the “white” colonies of Great Britain had at the turn of the XIX-XX centuries had to build a new policy of relations, taking into account the influence of the United States on them, and the general decline of economic and military-strategic influence of Britain in the world, and the militarization of other leading countries. As a result, a commonwealth is formed instead of an empire. With regard to other dependent territories, there is also a change in policy towards the liberalization of colonial rule and concessions to local elites. In the late ХІХ – early ХІХ centuries the newly industrialized powers (Germany, Italy, and Japan) sought to seize the colonies to reaffirm their new status in the world, the great colonial powers of the past (Spain, Portugal, and the Netherlands) sought to retain what remained to preserve their international prestige, and Russia sought to expand. The largest colonial empires, Great Britain and France, were interested in maintaining the status quo. In the colonial policy of the United Kingdom, it is possible to trace a certain line related to attempts to preserve the situation in their remote possessions and not to get involved in conflicts and costly measures where this can be avoided. In this sense, the British government showed some flexibility and foresight – the relative weakening of the military and economic power of the empire due to the emergence of new states, as well as the achievement of certain self-sufficiency, made it necessary to reconsider traditional foreign policy. Colonies are increasingly no longer seen as personal acquisitions of states, and policy toward these territories is increasingly seen as a common deal of the international community and even its moral duty. The key role here was to be played by Great Britain, which was one of the first to form the foundations of a “neocolonial” system that presupposes a solidarity policy of Western countries towards the rest of the world under the auspices of London. Colonial system in the late ХІХ – early ХІХ century underwent a major transformation, which was associated with a set of factors, the main of which were – the emergence of new industrial powers on the world stage, the internal evolution of the British Empire, changes in world trade, the emergence of new weapons, general growth of national and religious identity and related with this contradiction. The fact that the First World War did not solve many problems, such as Japanese expansionism or British marinism, and caused new ones, primarily such as the Bolshevik coup in Russia and the coming to power of the National Socialists in Germany, the implementation of the above trends stretched to later moments.

The French jurist, Méderic Louis Élie Moreau de Saint-Méry (1750-1819), was driven into exile during the French Revolution by Robespierre's accession to power. From 1794 to 1798 Moreau lived in the United States. In the journal he kept during these years, he described American young girls as follows: American girls are pretty, and their eyes are alive with expression; but their complexions are wan, bad teeth spoil the appearance of their mouths, and there is also something disagreeable about the length of their legs. In general, however, they are of good height, are graceful, and, in enumerating their charms, one must not forget the shapeliness of their breasts. Philadelphia has thousands of beauties between fourteen and eighteen. To offer but a single proof: on the north side of Market Street, between Third and Fifth Street, on a single winter's day I saw four hundred young maidens promenading, each one of whom would surely have been followed in Paris, a seductive tribute that could be offered by perhaps no other city in the world. But these girls soon became pale, and an indisposition which is reckoned among the most unfavorable for the maintenance of the freshness of youth is very common among them. They have thin hair and bad teeth, and are given to nervous illnesses. The elements which embellish beauty, or rather which compose and order it, are not often bestowed by the graces. Finally, they are charming, adorable at fifteen, dried up at twenty-three, old at thirty-five, decrepit at forty or fifty.

The American poet Robert Frost famously mused on whether the world will end in fire or in ice. Nuclear weapons can deliver both. The fire is obvious: modern hydrogen bombs duplicate on the surface of the earth the enormous thermonuclear energies of the Sun, with catastrophic consequences. But it might be a nuclear cold that kills the planet. A nuclear war with as few as 100 hundred weapons exploded in urban cores could blanket the Earth in smoke, ushering in a years-long nuclear winter, with global droughts and massive crop failures. The nuclear age is now entering its seventh decade. For most of these years, citizens and officials lived with the constant fear that long-range bombers and ballistic missiles would bring instant, total destruction to the United States, the Soviet Union, many other nations, and, perhaps, the entire planet. Fifty years ago, Nevil Shute’s best-selling novel, On the Beach, portrayed the terror of survivors as they awaited the radioactive clouds drifting to Australia from a northern hemisphere nuclear war. There were then some 7000 nuclear weapons in the world, with the United States outnumbering the Soviet Union 10 to 1. By the 1980s, the nuclear danger had grown to grotesque proportions. When Jonathan Schell’s chilling book, The Fate of the Earth, was published in 1982, there were then almost 60,000 nuclear weapons stockpiled with a destructive force equal to roughly 20,000 megatons (20 billion tons) of TNT, or over 1 million times the power of the Hiroshima bomb. President Ronald Reagan’s ‘Star Wars’ anti-missile system was supposed to defeat a first-wave attack of some 5000 Soviet SS-18 and SS-19 missile warheads streaking over the North Pole. ‘These bombs’, Schell wrote, ‘were built as “weapons” for “war”, but their significance greatly transcends war and all its causes and outcomes. They grew out of history, yet they threaten to end history. They were made by men, yet they threaten to annihilate man’.

This chapter examines how ecumenical American Protestants sought to come to Europe’s “spiritual aid” through carrying out a “Marshall Plan for the Churches.” By the summer of 1947, these Protestant ecumenists were preparing to rebuild European churches, distribute material aid across the continent, and promote theological exchange across the Atlantic. All the while, they also sought to strengthen the standing of democracy and capitalism in Europe and, in particular, to bolster European spiritual defenses against communism. While German and European Protestants welcomed ecumenical aid, they also protested the Cold War interests of the United States. In particular, they challenged American ecumenists for contributing to the spread of what they deemed a new kind of American imperial order in the world. In response, a growing number of Europeans called on ecumenical Protestants across the North Atlantic to become a “third way” spiritual force between American democracy and Soviet communism.

AbstractWe examine reforecasts of flash droughts over the United States for the late spring (April–May), midsummer (June–July), and late summer/early autumn (August–September) with lead times up to 3 pentads based on the NOAA second-generation Global Ensemble Forecast System reforecasts version 2 (GEFSv2). We consider forecasts of both heat wave and precipitation deficit (P deficit) flash droughts, where heat wave flash droughts are characterized by high temperature and depletion of soil moisture and P deficit flash droughts are caused by lack of precipitation that leads to (rather than being the cause of) high temperature. We find that the GEFSv2 reforecasts generally capture the frequency of occurrence (FOC) patterns. The equitable threat score (ETS) of heat wave flash drought forecasts for late spring in the regions where heat wave flash droughts are most likely to occur over the north-central and Pacific Northwest regions is statistically significant up to 2 pentads. The GEFSv2 reforecasts capture the basic pattern of the FOC of P-deficit flash droughts and also are skillful up to lead about 2 pentads. However, the reforecasts overestimate the P-deficit flash drought FOC over parts of the Southwest in late spring, leading to large false alarm rates. For autumn, the reforecasts underestimate P-deficit flash drought occurrence over California and Nevada. The GEFSv2 reforecasts are able to capture the approximately linear relationship between evaporation and soil moisture, but the lack of skill in precipitation forecasts limits the skill of P-deficit flash drought forecasts.

Inland waterways provide more opportunities for the conservation and improvement of the environment and the provision of amenity, sports, and recreation, facilities than do any other means of transport. The demand for more space for leisure pursuits is world-wide, and is accompanied by a growing appreciation of the need for environmental quality and conservation of Nature in catering for this demand. Thus in seeking solutions to related leisure, environmental, energy, and transport problems, authorities everywhere are coming to recognize the unique potential of inland water in meeting the concerns and wishes of modern society.Britain, with an unparalleled exclusively amenity waterways network, leads the world in the amenity development and utilization of inland waterways. The United States is broadening its objectives to encompass amenity development within the framework of traditional commercial-priority development of its waterways. Canada has launched the most sweeping and spectacular amenity waterway corridor development in history. France has begun actively to promote ‘tourisme fluvial’, while the Netherlands is progressing with integrated planning to harmonize the interests of commercial navigation with recreation and Nature conservation. The projected waterways link between the North and Black Seas has fostered amenity waterway development by all states along the Danube. Russia, too, is beginning to cater to the requirements of increasing numbers of water-oriented leisure seekers. Many other countries, including Portugal, are looking to the development of navigable waterways for leisure pursuits to help solve mounting national problems.

With the rise of factory farming, milk is now almost an unnatural operation. The modern dairy farm can have hundreds, even thousands of cows. Today’s average dairy cow produces six to seven times as much milk as she did a century ago. Currently, the United States is the largest producer of milk in the world, followed by India and China. India being one of the largest milk producer around the world, has to import a part of Milk products and its exports are negligible in the World Export Share. This paper tries to examine the issues regarding ‘Export Performance of Dairy Industry of India’: Trends, Challenges and suggestions for improving the trade situation. The existing Literature has been reviewed accordingly comprising Trade Exports, Imports and the factors which are affecting the Milk Production in country. The Objectives of the study is to find out the reasons for the low per unit production, Imports and negligible exports. In Nutshell, it can be said that there are many unexplored areas in which researchers can explore the findings which can be helpful in achieving trade balance of the Indian Economy.

Background: Epilepsy is a chronic neurological disease with the highest incidence in the world, affecting 1.3% of the Brazilian inhabitants. On average, 10% of the world population can be affected by an epileptic seizure. Thus, knowledge of the epidemiology of hospitalizations for epilepsy enables better health planning. Objective: To analyze epidemiology of hospitalizations in Brazil’s regions in 2015-2019. Methods: It is an observational and retrospective study of the descriptive epidemiological profile, using data from the Hospital Information System (SIH/ DATASUS). Variables: year, region, age group, sex and color/race. Results: There were 263,881 hospitalizations from 2015 to 2019 in Brazil. The Southeast region has the highest hospitalization rates between 2015 and 2019, reaching 42.32% of the cases, while the North region has the smallest, adding 5.5% (n = 14,530). In the epidemiological profile of hospitalizations prevails: the male gender, with 57.65% (n = 152,134), surpassing in 36.14% the female gender, with 111,747; the age group of 1-4 years (n = 45,702), exceeding in 378,9% the age group greater than or equal to 80 years (n = 9,543); the brown race, with 36% (n = 94,091), followed by white (34.4%), black (3.8%), yellow (1.2%) and indigenous (0.14%). Conclusion:There was a higher prevalence of hospitalizations for male epilepsy, aged 1-4 years, brown race and in the Southeast region. Therefore, through this study, resolutive actions can be taken in the face of such problems.

After peace talks began in Paris, the female delegation of Nguyen Thi Binh, foreign minister of the Provisional Revolutionary Government (PRG) of South Viet Nam, spearheaded people's diplomatic efforts as Binh’s own poised, determined, and feminine presence on the world stage inspired countless women around the world. Complementing the PRG women's efforts, U.S. women activists continued to travel to Viet Nam—both North and South. The context of American women's activism had shifted in two significant ways, however. First, the incarceration of Vietnamese political prisoners in South Viet Nam in "tiger cages" came to light in July 1970. Second, the context of growing feminist sentiment colored the views of women peace activists. The U.S. military's complicity in the deplorable prison conditions in the South led women peace activists to perceive social inequalities in the United States as they also noted the distinguished positions of women in North Viet Nam. They came to describe Vietnamese women in the North as having gained "liberation" and claimed South Vietnamese society had actually deteriorated because of U.S. intervention.
