Aruncus Dioicus
''Aruncus dioicus'', known as goat's beard, buck's-beard or bride's feathers, is a flowering herbaceous perennial plant in the family Rosaceae, found in Europe, Asia, and eastern and western North America. It is the type species of the genus ''Aruncus''. It has alternate, pinnately compound leaves, on thin, stiff stems, with plumes of feathery white or cream flowers borne in summer. The Latin specific epithet ''dioicus'' means "having the male reproductive organs on one plant, and the female on another". Description The species is from tall, with compound leaves consisting of 3 or 5 leaflets. Very small, 5-petaled white or cream flowers are displayed in showy panicles, blooming in late spring to early summer. Male and female flowers are borne on different plants. The flower spikes rise high above the plant, adding to the showiness of the species. Plants with male flowers have a showier bloom than the ones with female flowers.

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the '' Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the par ...

Korea National Arboretum
Korea National Arboretum () is an over-500-year-old arboretum located in Pocheon city of Gyeonggi Province of South Korea. It is widely known as "Gwangneung Forest ()" by the public. It is designated as UNESCO World Network of Biosphere Reserve and the country's 11th natural monument. Its history can be traced back to Joseon Dynasty. The planting of large forests started during the reign of Sejo of Joseon. He and Queen Jeonghui designated the area for a tomb which later named ''Gwangneung.'' Their tomb is one of Royal Tombs of the Joseon Dynasty, a UNESCO World Heritage Site. Following the construction of the tomb, it and its surrounding areas were designated as royal forest and kept under strict protection which lasted throughout post-Joseon history. The area was devastated during the Korean war. From 1983 to 1987, the central government went under project to develop the area as an arboretum with a forest museum. Upon its completion in 1987, it was finally open to the general pub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black ...

Jurkat Cells
Jurkat cells are an immortalized line of human T lymphocyte cells that are used to study acute T cell leukemia, T cell signaling, and the expression of various chemokine receptors susceptible to viral entry, particularly HIV. Jurkat cells can produce interleukin 2, and are used in research involving the susceptibility of cancers to drugs and radiation. History The Jurkat cell line (originally called JM) was established in the mid-1970s from the peripheral blood of a 14-year-old boy with T cell leukemia. Different derivatives of the Jurkat cell line that have been mutated to lack certain genes can now be obtained from cell culture banks. Examples of derivatives * The JCaM1.6 cell line is deficient in Lck activity due to the deletion of part of the ''LCK'' gene (exon 7) from the ''LCK'' transcript. * J.RT3-T3.5 cells have a mutation in the T cell receptor beta chain locus precluding expression of this chain. This affects the cells in several ways; they do not express surface C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cytotoxicity
Cytotoxicity is the quality of being toxic to cells. Examples of toxic agents are an immune cell or some types of venom, e.g. from the puff adder (''Bitis arietans'') or brown recluse spider (''Loxosceles reclusa''). Cell physiology Treating cells with the cytotoxic compound can result in a variety of cell fates. The cells may undergo necrosis, in which they lose membrane integrity and die rapidly as a result of cell lysis. The cells can stop actively growing and dividing (a decrease in cell viability), or the cells can activate a genetic program of controlled cell death (apoptosis). Cells undergoing necrosis typically exhibit rapid swelling, lose membrane integrity, shut down metabolism, and release their contents into the environment. Cells that undergo rapid necrosis in vitro do not have sufficient time or energy to activate apoptotic machinery and will not express apoptotic markers. Apoptosis is characterized by well defined cytological and molecular events including a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friuli
Friuli ( fur, Friûl, sl, Furlanija, german: Friaul) is an area of Northeast Italy with its own particular cultural and historical identity containing 1,000,000 Friulians. It comprises the major part of the autonomous region Friuli Venezia Giulia, i.e. the administrative provinces of Udine, Pordenone, and Gorizia, excluding Trieste.

Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars. Similar awards The award should not b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Temperateness
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arct ...
