Hedvig Lovén
Hedvig Karolina Lovisa Santesson (née Lovén) was a Swedish botanist who made significant contributions to the field of plant respiration in the late 19th century. Early life Born on December 13, 1867, in Stockholm, Sweden, she was the daughter of , a Swedish physician and politician, and Elisabeth Johanna Emilia (née von Julin), who hailed from Finland. Scientific work Lovén pursued her education at a type of Scandinavian college known as Hogskola, where she developed a keen interest in botany. Between 1888 and 1892, Hedvig Lovén published three academic papers on botany and conducted extensive research on plant respiration Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which stores chemical energy in a biologically accessible form.

Monocotyledons
Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are flowering plants whose seeds contain only one embryonic leaf, or cotyledon. A monocot taxon has been in use for several decades, but with various ranks and under several different names. The APG IV system recognises its monophyly but does not assign it to a taxonomic rank, and instead uses the term "monocots" to refer to the group. Monocotyledons are contrasted with the dicotyledons, which have two cotyledons. Unlike the monocots however, the dicots are not monophyletic and the two cotyledons are instead the ancestral characteristic of all flowering plants. Botanists now classify dicots into the eudicots ("true dicots") and several basal lineages from which the monocots emerged. The monocots are extremely important economically, culturally, and ecologically, and make up a majority of plant biomass used in agriculture. Common crops such as dates, onions, garlic, rice, wheat, maize, and su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century Swedish Women Scientists
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm ...

Scientists From Stockholm
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1867 Births
There were only 354 days this year in the newly purchased territory of Alaska. When the territory transferred from the Russian Empire to the United States, the calendric transition from the Julian to the Gregorian Calendar was made with only 11 days instead of 12 during the 19th century. This change was made due to the territorial and Geopolitics, geopolitical shift from the Asian to the American side of the International Date Line.

Karolinska Institute
The Karolinska Institute (KI; ; sometimes known as the (Royal) Caroline Institute in English) is a research-led medical university in Solna within the Stockholm urban area of Sweden and one of the foremost medical research institutes globally. The Nobel Assembly at the Karolinska Institute awards the Nobel Prize in Physiology or Medicine. The assembly consists of fifty professors from various medical disciplines at the university. The current vice-chancellor of Karolinska Institute is Annika Östman Wernerson, who took office in March 2023. The Karolinska Institute was founded in 1810 on the island of Kungsholmen on the west side of Stockholm; the main campus was relocated decades later to Solna, just outside Stockholm. A second campus was established more recently in Flemingsberg, Huddinge, south of Stockholm. The institute also has a Centre for Reparative Medicine, consisting of two nodes, one in Stockholm and one in Hong Kong. The Karolinska Institute is Sweden's thir ...

Cell Fusion
Cell fusion is an important cellular process in which several uninucleate cells (cells with a single nucleus) combine to form a multinucleate cell, known as a syncytium. Cell fusion occurs during differentiation of myoblasts, osteoclasts and trophoblasts, during embryogenesis, and morphogenesis. Cell fusion is a necessary event in the maturation of cells so that they maintain their specific functions throughout growth. History In 1839, Theodor Schwann, in his '' Microscopical Researches,'' expanded upon the theory that all living organisms are composed of cells when he added that discrete cells are the basis of life. Schwann observed that in certain cells the walls and cavities of the cells coalesce ('' verschmelzen'') together. This observation provided the first hint that cells fuse. It was not until 1960 that cell biologists deliberately fused cells for the first time. To fuse the cells, biologists combined isolated mouse cells and induced fusion of their outer membrane ...

Leopold Kny
Carl Ignaz Leopold Kny (6 July 1841 – 26 June 1916) was a German botanist, notable as a specialist in research involving the morphology of fungi and cryptogams. He is best known for his production of botanical wall-charts, the ''Botanische Wandtafeln''. Early life Kny was born in Breslau on 6 July 1841. At the age of 17, Kny graduated from high school and began to attend the University of Wroclaw. Initially he studied business to follow his father's profession but he was inspired by Heinrich Göppert and Ferdinand Cohn, and he decided to devote himself to the study of botany. In 1860, he took up studies in Munich under the direction of Carl Nägeli. He completed his doctorate in Berlin, where he was a pupil of Alexander Braun He studied leafless liverworts and then went to Sicily and Madeira to recover his health. He began to collect algae samples from southern Europe for his studies. He habilitated in 1867.Kugler, Hans, "Kny, Leopold" in: New German Biography 12 (1979), p. 2 ...
