Marta Estrada
Marta Estrada Miyares (born 1946) is a Catalan researcher, with a career in oceanography and marine biology. Her most prominent studies are based on the physiological characterization and ecological impact of algae and phytoplankton. Career Marta Estrada's parents were both amateur archaeologists. She was born in Granollers, where she started her studies in the town's public elementary school. She later moved to Barcelona, where she followed her education in Institut Verdaguer. She graduated with Honours and a brilliant academic record both in Biological Sciences (1968) and Medicine and Surgery (1970) at the University of Barcelona. At the end of her bachelor's studies, in 1969, she was awarded with the Prize for the most outstanding graduate of her BSc degree, the National Graduation Award and the Llaç de l' Orde Civil d'Alfons X el Savi, a Spanish award for excellence in the education, science and research fields. Prior to that, in 1968, she received a scholarship to deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granollers, Catalonia
Granollers () is a city in central Catalonia, about 30 kilometres north-east of Barcelona. It is the capital and most densely populated city in the comarca of Vallès Oriental. Granollers is now a bustling business centre, having grown from a town dominated by Catalonia's textile industry that was prominent during the 19th Century. However, in the southern portion of the municipality, the Palou area retains the agricultural characteristics of the past. Granollers forms a conurbation with Canovelles, Les Franqueses del Vallès and the district of La Torreta in La Roca del Vallès. The city is crossed by the Congost river, a tributary of the Besòs. It is considered to be the other jewel of the Barcelona metropolitan area. It is around 25 km north-east of the centre of Barcelona. History Spanish Civil War During the Spanish Civil War, in May 1938, the Bombing of Granollers was carried out by Italian bombers, resulting in 100-200 civilian fatalities. Notable land ...

Primary Production
In ecology, primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide. It principally occurs through the process of photosynthesis, which uses light as its source of energy, but it also occurs through chemosynthesis, which uses the oxidation or reduction of inorganic chemical compounds as its source of energy. Almost all life on Earth relies directly or indirectly on primary production. The organisms responsible for primary production are known as ''primary producers'' or autotrophs, and form the base of the food chain. In terrestrial ecoregions, these are mainly plants, while in aquatic ecoregions algae predominate in this role. Ecologists distinguish primary production as either ''net'' or ''gross'', the former accounting for losses to processes such as cellular respiration, the latter not. Overview Primary production is the production of chemical energy in organic compounds by living organisms. The main source of this energy is su ...

Nitrate
Nitrate is a polyatomic ion A polyatomic ion, also known as a molecular ion, is a covalent bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero. The term molecule may or may no ... with the chemical formula . salt (chemistry), Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. Almost all inorganic nitrates are solubility, soluble in water. An example of an insoluble nitrate is bismuth oxynitrate. Structure The ion is the conjugate acid, conjugate base of nitric acid, consisting of one central nitrogen atom surrounded by three identically bonded oxygen atoms in a trigonal planar arrangement. The nitrate ion carries a formal charge of −1. This charge results from a combination formal charge in which each of the three oxygens carries a − charge, whereas the nitrogen carries a +1 charge, all these adding up to formal c ...

Biomass (ecology)
The biomass is the mass of living biological organisms in a given area or ecosystem at a given time. Biomass can refer to ''species biomass'', which is the mass of one or more species, or to ''community biomass'', which is the mass of all species in the community. It can include microorganisms, plants or animals. The mass can be expressed as the average mass per unit area, or as the total mass in the community. How biomass is measured depends on why it is being measured. Sometimes, the biomass is regarded as the natural mass of organisms ''in situ'', just as they are. For example, in a salmon fishery, the salmon biomass might be regarded as the total wet weight the salmon would have if they were taken out of the water. In other contexts, biomass can be measured in terms of the dried organic mass, so perhaps only 30% of the actual weight might count, the rest being water. For other purposes, only biological tissues count, and teeth, bones and shells are excluded. In some appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Washington
The University of Washington (UW, simply Washington, or informally U-Dub) is a public research university in Seattle, Washington. Founded in 1861, Washington is one of the oldest universities on the West Coast; it was established in Seattle approximately a decade after the city's founding. The university has a 703 acre main campus located in the city's University District, as well as campuses in Tacoma and Bothell. Overall, UW encompasses over 500 buildings and over 20 million gross square footage of space, including one of the largest library systems in the world with more than 26 university libraries, art centers, museums, laboratories, lecture halls, and stadiums. The university offers degrees through 140 departments, and functions on a quarter system. Washington is the flagship institution of the six public universities in Washington state. It is known for its medical, engineering, and scientific research. Washington is a member of the Association of American Universiti ...

Algal Bloom
An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. The term ''algae'' encompasses many types of aquatic photosynthetic organisms, both macroscopic multicellular organisms like seaweed and microscopic unicellular organisms like cyanobacteria. ''Algal bloom'' commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest. Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution), entering the aquatic system and causing excessive growth of algae. An algal bloom affects the whole ecosystem. Consequences range from the benign feeding of higher trophic levels to more harmful effects like blocking sunlight from reaching other organ ...

Institute Of International Education
The Institute of International Education (IIE) is a 501(c) organization which focuses on international student exchange and aid, foreign affairs, and international peace and security. IIE creates programs of study and training for students, educators and professionals from various sectors. The organization says its mission is to "build more peaceful and equitable societies by advancing scholarship, building economies and promoting access to opportunity". History The institute was established in 1919 at the cessation of World War I. Nobel Peace Prize winners Nicholas Murray Butler, president of Columbia University, Elihu Root, former secretary of state, and Stephen Duggan, Sr., professor of political science at the College of the City of New York (and IIE's first president) formed the Institute of International Education with the idea that educational exchange would incite understanding between nations. IIE president Stephen Duggan influenced the U.S. government to create a new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
