Montreal
Montreal ( ; officially Montréal, ) is the second-most populous city in Canada and most populous city in the Canadian province of Quebec. Founded in 1642 as '' Ville-Marie'', or "City of Mary", it is named after Mount Royal, the triple-peaked hill around which the early city of Ville-Marie is built. The city is centred on the Island of Montreal, which obtained its name from the same origin as the city, and a few much smaller peripheral islands, the largest of which is Île Bizard. The city is east of the national capital Ottawa, and southwest of the provincial capital, Quebec City. As of 2021, the city had a population of 1,762,949, and a metropolitan population of 4,291,732, making it the second-largest city, and second-largest metropolitan area in Canada. French is the city's official language. In 2021, it was spoken at home by 59.1% of the population and 69.2% in the Montreal Census Metropolitan Area. Overall, 85.7% of the population of the city of Montre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robin Reed (biologist)
Robin Elizabeth Reed (August 1, 1956 – July 23, 2022) was an American professor of cell biology at the Harvard Medical School. Her research considered the molecular mechanisms that underpin neurodegenerative disease. Early life and education Reed was born on August 1, 1956, in Akron, Ohio, to Nancy Nobel Reed and Lawrence Andrew Reed. She was an equestrian, taking part in both dressage and show jumping. Reed was an undergraduate at Hiram College in Ohio, where she majored in biology. She joined Yale University as a technician, where she took advanced science courses to prepare herself for doctoral research there. For her PhD, she worked in the laboratory of Sidney Altman and was the first to clone and sequence the RNA gene. Altman acknowledged her contributions to science in his Nobel Prize lecture. Reed moved to Harvard University for postdoctoral research, where she started working on pre-RNA splicing with Tom Maniatis. Reed characterized the branchpoint sequence in mamm ...

Enterobacteria Phage T4
Escherichia virus T4 is a species of bacteriophages that infect ''Escherichia coli'' bacteria. It is a double-stranded DNA virus in the subfamily ''Tevenvirinae'' from the family Myoviridae. T4 is capable of undergoing only a lytic lifecycle and not the lysogenic lifecycle. The species was formerly named T-even bacteriophage, a name which also encompasses, among other strains (or isolates), Enterobacteria phage T2, Enterobacteria phage T4 and Enterobacteria phage T6. Use in research Dating back to the 1940s and continuing today, T-even phages are considered the best studied model organisms. Model organisms are usually required to be simple with as few as five genes. Yet, T-even phages are in fact among the largest and highest complexity virus, in which these phage's genetic information is made up of around 300 genes. Coincident with their complexity, T-even viruses were found to have the unusual base hydroxymethylcytosine (HMC) in place of the nucleic acid base cytosine ...

Acridine
Acridine is an organic compound and a nitrogen heterocycle with the formula C13H9N. Acridines are substituted derivatives of the parent ring. It is a planar molecule that is structurally related to anthracene with one of the central CH groups replaced by nitrogen. Like the related molecules pyridine and quinoline, acridine is mildly basic. It is an almost colorless solid, which crystallizes in needles. There are few commercial applications of acridines; at one time acridine dyes were popular, but they are now relegated to niche applications, such as with acridine orange. The name is a reference to the acrid odour and acrid skin-irritating effect of the compound. Isolation and syntheses Carl Gräbe and Heinrich Caro first isolated acridine in 1870 from coal tar. Acridine is separated from coal tar by extracting with dilute sulfuric acid. Addition of potassium dichromate to this solution precipitates acridine bichromate. The bichromate is decomposed using ammonia. Acridine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Collective Farming
Collective farming and communal farming are various types of, "agricultural production in which multiple farmers run their holdings as a joint enterprise". There are two broad types of communal farms: agricultural cooperatives, in which member-owners jointly engage in farming activities as a collective, and state farms, which are owned and directly run by a centralized government. The process by which farmland is aggregated is called collectivization. In some countries (including the Soviet Union, the Eastern Bloc countries, China and Vietnam), there have been both state-run and cooperative-run variants. For example, the Soviet Union had both kolkhozy (cooperative-run farms) and sovkhozy (state-run farms). Pre-20th century history A small group of farming or herding families living together on a jointly managed piece of land is one of the most common living arrangements in all of human history, having co-existed and competed with more individualistic forms of ownership (as ...

Białystok
Białystok is the largest city in northeastern Poland and the capital of the Podlaskie Voivodeship. It is the tenth-largest city in Poland, second in terms of population density, and thirteenth in area. Białystok is located in the Białystok Uplands of the Podlachian Plain on the banks of the Biała River, by road northeast of Warsaw. It has historically attracted migrants from elsewhere in Poland and beyond, particularly from Central and Eastern Europe.

Immigration To Canada
According to the 2021 Canadian census, immigrants in Canada number 8.3 million persons and make up approximately 23 percent of Canada's total population. This represents the eighth-largest immigrant population in the world, while the proportion represents one of the highest ratios for industrialized Western countries. Following Canada's confederation in 1867, immigration played an integral role in helping develop vast tracts of land.Cheatham, Amelia. 2020 August 3.What Is Canada's Immigration Policy? ''Council on Foreign Relations''. During this era, the Canadian Government would sponsor information campaigns and recruiters to encourage settlement in rural areas; however, this would primarily be only towards those of European and Christian backgrounds, while others—particularly Buddhist, Shinto, Sikh, Muslim, and Jewish immigrants—as well as the poor, ill, and disabled, would be less than welcome.Belshaw, John Douglas. 2016.Post-War Immigration" Ch. 5 §11 in ''Canadi ...
