Wolfgang Finkelnburg
Wolfgang Karl Ernst Finkelnburg (5 June 1905 – 7 November 1967)[1] was a German physicist who made contributions to spectroscopy, atomic physics, the structure of matter, and high-temperature arc discharges. His vice-presidency of the Deutsche Physikalische Gesellschaft 1941-1945, was influential in that organization’s ability to assert its independence from National Socialist policies. F

Wolffia Sp. For Space BLSS.
Plants in the genus Wolffia have a cosmopolitan distribution, populating the lentic ecosystems in almost all the continents except the Antarctic and Arctic regions. Wolffia is a genus of plants with 11 species and including both the fastest-growing angiospermand the smallest flowering plants(a). As is the case for other species in the family, plants in the genus Wolffia consist of a single physical unit termed frond, or thallus, and interpreted as a leaf and stem in an embryonic stage of development.

Wolf Population Management
Wolf population management should be guided by knowledge on abundance, demographic and genetic structure, and reproduction. Such information is relevant both locally and internationally if populations of protected species inhabit areas shared by several states.

Wolf Distribution
Wolf distribution is the species distribution of the wolf (Canis lupus). Originally, wolves occurred in Eurasia above the 12th parallel north and in North America above the 15th parallel north. However, deliberate human persecution has reduced the species' range to about one-third, because of livestock predation and fear of wolf attacks on humans. The species is now extirpated (made locally extinct) in much of Western Europe, Mexico, and the contiguous United States , and completely from the British Isles and the Japanese archipelago. In modern history, the gray wolf occurs mostly in wilderness and remote areas, particularly in Canada , Alaska, the Northern United States, Europe and Asia from about the 75th parallel north to the 12th parallel north. Wolf population declines have been arrested since the 1970s, and have fostered recolonization and reintroduction in parts of its former range, due to legal protection, changes in land-use and rural human population shifts to cities. Competition with humans for livestock and game species, concerns over the danger posed by wolves to people, and habitat fragmentation pose a continued threat to the species. Despite these threats, because of the gray wolf's relatively widespread range and stable population, it is classified as Least Concern on the IUCN Red List. In Africa the population of wolves is limited to the northern regions with the African golden wolf (Canis lupaster) north of the Sahara and the Ethiopian wolf (Canis simensis) in Ethiopia.

Wolbachia
Wolbachia is an intracellular bacterium that occurs in arthropods and in filarial worms. First described nearly a century ago in the reproductive tissues of Culex pipiens mosquitoes, Wolbachia is now known to occur in roughly 50% of insect species, and has been considered the most abundant intracellular bacterium on earth. In insect hosts, Wolbachia modifies reproduction in ways that facilitate spread of the microbe within the host population, but otherwise is relatively benign. In this “gene drive” capacity, Wolbachia provides a tool for manipulating mosquito populations. In mosquitoes, Wolbachia causes cytoplasmic incompatibility, in which the fusion of egg and sperm nuclei is disrupted, and eggs fail to hatch, depending on the presence/absence of Wolbachia in the parent insects. Recent findings demonstrate that Wolbachia from infected insects can be transferred into mosquito species that do not host a natural infection. When transinfected into Aedes aegypti, an important vector of dengue and Zika viruses, Wolbachia causes cytoplasmic incompatibility and, in addition, decreases the mosquito’s ability to transmit viruses to humans.

Woke
Woke (/ˈwoʊk/) as a political term of African American origin refers to a perceived awareness of issues concerning social justice and racial justice. It is derived from the African-American Vernacular English expression "stay woke", whose grammatical aspect refers to a continuing awareness of these issues. By the late 2010s, woke had been adopted as a more generic slang term broadly associated with left-wing politics, socially liberal causes, feminism, LGBT activism, and cultural issues (with the terms woke culture and woke politics also being used). It has been the subject of memes, ironic usage and criticism. Its widespread use since 2014 is a result of the Black Lives Matter movement.

WO3 and Ionic Liquids -2
The possibility of using an IL to enhance WO3 dispersion on an inorganic support, ensuring the formation of composites with a very large number of exposed catalytic sites, is reported. In addition, in some cases the IL was demonstrated to be able to direct the morphology of WO3 particles.
