Emigrate
Emigration is the act of leaving a resident country or place of residence with the intent to settle elsewhere (to permanently leave a country). Conversely, immigration describes the movement of people into one country from another (to permanently move to a country). A migrant ''emigrates'' from their old country, and ''immigrates'' to their new country. Thus, both emigration and immigration describe International migration, migration, but from different countries' perspectives. Demographers examine push and pull factors for people to be pushed out of one place and attracted to another. There can be a desire to escape negative circumstances such as shortages of land or jobs, or unfair treatment. People can be pulled to the opportunities available elsewhere. Fleeing from oppressive conditions, being a refugee and Asylum seeker, seeking asylum to get Refugee#Refugee status, refugee status in a foreign country, may lead to permanent emigration. Forced displacement refers to group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Pathology
Plant pathology or phytopathology is the scientific study of plant diseases caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Plant pathology involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Plant pathogenicity Plant pathogens, organisms that cause infectious plant diseases, include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. In most plant pathosystems, virulence depends on hydrolases and enzymes that degrade the cell wall. The vast majority of these act on pectins (for example, pectinesterase, pectate lyase, and pectinases). For microbes, the cell wall polysaccharides are both a food source and a barrier to be overcome. Many path ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refugee Camps
A refugee camp is a temporary settlement built to receive refugees and people in refugee-like situations. Refugee camps usually accommodate displaced people who have fled their home country, but camps are also made for internally displaced people. Usually, refugees seek asylum after they have escaped war in their home countries, but some camps also house environmental and economic migrants. Camps with over a hundred thousand people are common, but as of 2012, the average-sized camp housed around 11,400. They are usually built and run by a government, the United Nations, international organizations (such as the International Committee of the Red Cross), or non-governmental organization. Unofficial refugee camps, such as Idomeni in Greece or the Calais jungle in France, are where refugees are largely left without the support of governments or international organizations. Refugee camps generally develop in an impromptu fashion with the aim of meeting basic human needs fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intern
An internship is a period of work experience offered by an organization for a limited period of time. Once confined to medical graduates, internship is used to practice for a wide range of placements in businesses, non-profit organizations and government agencies. They are typically undertaken by students and graduates looking to gain relevant skills and experience in a particular field. Employers benefit from these placements because they often recruit employees from their best interns, who have known capabilities, thus saving time and money in the long run. Internships are usually arranged by third-party organizations that recruit interns on behalf of industry groups. Rules vary from country to country about when interns should be regarded as employees. The system can be open to exploitation by unscrupulous employers. Internships for professional careers are similar in some ways. Similar to internships, apprenticeships transition students from vocational school into the workf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Soviets invaded Poland on 17 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German–Soviet Frontier Treaty. The aim of the invasion was to disestablish Poland as a sovereign country, with its citizens destined for extermination. German and Slovak forces invaded Poland from the north, south, and west the morning after the Gleiwitz incident. As the Wehrmacht advanced ...

Rickettsia Prowazekii
''Rickettsia prowazekii'' is a species of gram-negative, obligate intracellular parasitic, aerobic bacilliform bacteria of class Alphaproteobacteria that is the etiologic agent of epidemic typhus, transmitted in the feces of lice. In North America, the main reservoir for ''R. prowazekii'' is the flying squirrel. ''R. prowazekii'' is often surrounded by a protein microcapsular layer and slime layer; the natural life cycle of the bacterium generally involves a vertebrate and an invertebrate host, usually an arthropod, typically the human body louse. A form of ''R. prowazekii'' that exists in the feces of arthropods remains stably infective for months. ''R. prowazekii'' also appears to be the closest semi-free-living relative of mitochondria, based on genome sequencing. History Discovery Henrique da Rocha Lima, a Brazilian doctor, discovered this bacterium in 1916. He named it after his colleague Stanislaus von Prowazek, who had died from typhus in 1915.
