Frederick Blackman
Frederick Frost Blackman FRS (25 July 1866 – 30 January 1947) was a British plant physiologist. Frederick Blackman was born in Lambeth, London to a doctor. He studied medicine at St. Bartholomew's Hospital, graduating MA. In the subsequent years, he studied natural sciences at the University of Cambridge and was awarded DSc. He conducted research on plant physiology, in particular photosynthesis, in Cambridge until his retirement in 1936. Gabrielle Matthaei was his assistant until 1905. He was elected in May 1906 a Fellow of the Royal Society, his candidature citation reading "Fellow of St John's College, Cambridge. Ex-Lecturer and now Reader in Botany in the University." He has made distinguished investigations in plant physiology. In 1921 he was awarded the Royal Medal and in 1923 delivered the Croonian lecture.

Lambeth
Lambeth () is a district in South London, England, in the London Borough of Lambeth, historically in the County of Surrey. It is situated south of Charing Cross. The population of the London Borough of Lambeth was 303,086 in 2011. The area experienced some slight growth in the medieval period as part of the manor of Lambeth Palace. By the Victorian era the area had seen significant development as London expanded, with dense industrial, commercial and residential buildings located adjacent to one another. The changes brought by World War II altered much of the fabric of Lambeth. Subsequent development in the late 20th and early 21st centuries has seen an increase in the number of high-rise buildings. The area is home to the International Maritime Organization. Lambeth is home to one of the largest Lusophone, Portuguese-speaking communities in the UK, and is the second most commonly spoken language in Lambeth after English language, English.

People From Lambeth
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Dorothea Pertz
Dorothea Frances Matilda "Dora" Pertz FLS (14 March 1859 – 6 March 1939) was a British botanist. She co-authored five papers with Francis Darwin, Charles Darwin's son. She was made a Fellow of the Linnean Society, among the first women admitted to full membership. Biography Dora Pertz was born in London on 14 March 1859 to Georg Heinrich Pertz and his second wife, Leonora Horner, daughter of Leonard Horner, who was a progressive intellectual and an adamant supporter of Darwinism, a fact he noted in his final address. She grew up in a family where women were well-educated and intellectually active; one of her aunts was the botanist Katharine Murray Lyell, who was a biographer of Charles Lyell, her brother-in-law. Through family connections she met many prominent naturalists including Darwin. Pertz spent most of her youth in Berlin, where her father was Royal Librarian, though they visited England each year. After her father's death in 1876, Pertz moved to Florence wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jstor
JSTOR (; short for ''Journal Storage'') is a digital library founded in 1995 in New York City. Originally containing digitized back issues of academic journals, it now encompasses books and other primary sources as well as current issues of journals in the humanities and social sciences. It provides full-text searches of almost 2,000 journals. , more than 8,000 institutions in more than 160 countries had access to JSTOR.

Bowen, president of Princeton University from 1972 to 1988, founded JSTOR in 1994. JSTOR was originally conceived as a solution to one of the problems faced by libraries, especially research and university libraries, due to the increasing number of academic journals in existence. Most libraries found it prohibitively expensive in terms of cost and space to maintain a comprehen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name ''photosynthesis'', from the Greek ''phōs'' (), "light", and ''synthesis'' (), "putting together". Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth. Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromoph ...

Limiting Factor
A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system. The limiting factor is in a pyramid shape of organisms going up from the producers to consumers and so on. A factor not limiting over a certain domain of starting conditions may yet be limiting over another domain of starting conditions, including that of the factor. Overview The identification of a factor as limiting is possible only in distinction to one or more other factors that are non-limiting. Disciplines differ in their use of the term as to whether they allow the simultaneous existence of more than one limiting factor which (may then be called "co-limiting"), but they all require the existence of at least one non-limiting factor when the terms are used. There are several different possible scenarios of limitation when more than one factor is present. The first scenario, called ''single limitation'' occurs when only one factor, the one with maximum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
