Chemistry
Chemistry is the scientific study of the properties and behavior of matter. It is a physical science within the natural sciences that studies the chemical elements that make up matter and chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during chemical reaction, reactions with other chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the prop ...

People From Wiesloch
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ...

Exsiccata
Exsiccata (Latin, ''gen.'' -ae, ''plur.'' -ae) is a work with "published, uniform, numbered set[s] of preserved specimens distributed with printed labels". Typically, exsiccatae are numbered collections of dried herbarium Biological specimen, specimens or preserved biological sample (material), samples published in several duplicate sets with a common theme or title, such as ''Lichenes Helvetici exsiccati'' (see figure). Exsiccatae are regarded as scientific contributions of the editor(s) with characteristics from the library world (published booklets of scientific literature, with authors/ editing, editors, titles, often published in Serial (publishing), serial publications like journals and magazines and in Serial_(literature), serial formats with fascicles) and features from the herbarium world (uniform and numbered collections of duplicate herbarium specimens). Exsiccatae works represent a special method of scholarly communication. The text in the printed matters/published book ...

Das Pflanzenreich
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many herbaria and is followed by writers of many manuals and floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He also illustrated ''Das Pflanzenreich'' (1900–1953), ''Die Pf ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
