The German Wikipedia (German: deutschsprachige Wikipedia) is the German-language edition of Wikipedia, a free and publicly editable online encyclopedia. Founded in March 2001, it is the second-oldest, after the English Wikipedia, and with 2,459,141 articles, at present (2019) the fourth-largest edition of Wikipedia by number of articles, behind the English Wikipedia and the mostly bot-generated Swedish Wikipedia and Cebuano Wikipedia. It has the second-largest number of edits behind the English Wikipedia and over 260,000 disambiguation pages. On 7 November 2011, it became the second edition of Wikipedia, after the English edition, to exceed 100 million page edits.

It is the third edition, behind the English Wikipedia and the French Wikipedia by depth and by number of active users. It is the fourth edition, behind the English Wikipedia, the Spanish Wikipedia and the French Wikipedia by number of users. On 21 March 2019 the German Wikipedia went offline to inform users about the situation of the European Union's copyright law reformation, the Directive on Copyright in the Digital Single Market, which has been voted on in the European Parliament on 27 March 2019. Opponents of the reformation were concerned about the restriction of fundamental rights including a free press and the freedom of speech and arts.

X-Ray Emission Spectroscopy

Kevin Burrus, also known as Kevin UltraOmni (born 1958) is an American mentor, speaker, LGBTQ activist, and film producer who founded the ball culture House of Omni in 1979–which was renamed the House of UltraOmni in 1990–and has chapters across the country. He has become an authority on ball culture and has spoken in interviews about the movement. Omni is also the assistant director for the documentary How Do I Look NYC, produced by Wolfgang Busch which aims to correct misperceptions about ball culture.

In X-ray emission spectroscopy (XES), X-ray line spectra are measured with a spectral resolution sufficient to analyze the impact of the chemical environment on the X-ray line energy and on branching ratios.This is done by exciting electrons out of their shell and then watching the emitted photons of the recombinating electrons. It is possible to differentiate between.: The first XES experiments were published by Lindh and Lundquist in 1924

A loudspeaker is an electroacoustic transducer; a device which converts an electrical audio signal into a corresponding sound. The most widely used type of speaker in the 2010s is the dynamic speaker, invented in 1924 by Edward W. Kellogg and Chester W. Rice. The dynamic speaker operates on the same basic principle as a dynamic microphone, but in reverse, to produce sound from an electrical signal. When an alternating current electrical audio signal is applied to its voice coil, a coil of wire suspended in a circular gap between the poles of a permanent magnet, the coil is forced to move rapidly back and forth due to Faraday's law of induction, which causes a diaphragm (usually conically shaped) attached to the coil to move back and forth, pushing on the air to create sound waves. Besides this most common method, there are several alternative technologies that can be used to convert an electrical signal into sound. The sound source (e.g., a sound recording or a microphone) must be amplified or strengthened with an audio power amplifier before the signal is sent to the speaker. Speakers are typically housed in a speaker enclosure or speaker cabinet which is often a rectangular square box made of several forms of wood, or sometimes plastic. The enclosure's materials and design play an important role in the quality of the sound. The enclosure generally must be as stiff and non-resonant as practically possible. Where high fidelity reproduction of sound is required, multiple loudspeaker transducers are often mounted in the same enclosure, each reproducing a part of the audible frequency range (picture at right). In this case the individual speakers are referred to as "drivers" and the entire unit is called a loudspeaker. Drivers made for reproducing high audio frequencies are called tweeters, those for middle frequencies are called mid-range drivers, and those for low frequencies are called woofers. Extremely low frequencies (16Hz-~100Hz) may be reproduced by detached subwoofers. Smaller loudspeakers are found in devices such as radios, televisions, portable audio players, computers, and electronic musical instruments. Larger loudspeaker systems are used for music, sound reinforcement in theatres and concert halls, and in public address systems.

It is possible to differentiate between.:
* non-resonant XES (XES) 1.
* -measurements 2.
* Valence-to-Core (VtC/V2C)-measurements 3.
* ()-measurements
* resonant XES (RXES oder RIXS) 1.
* XAS+XES 2D-measurements 2.
* high-resolution XAS 3.
* 2p3d RIXS 4.
* Mössbauer-XES-combined measurements The first XES experiments were published by Lindh and Lundquist in 1924 In these early studies, the authors utilized the electron beam of an X-ray tube to excite core electrons and obtain the -line spectra of sulfur and other elements. Three years later, Coster and Druyvesteyn performed the first experiments using photonexcitation. Their work demonstrated that the electron beams produce artifacts, thus motivating the use of X-ray photons for creating the core hole. Subsequent experiments were carried out with commercial X-ray spectrometers, as well as with high-resolution spectrometers. While these early studies provided fundamental insights into the electronic configuration of small molecules, XES only came into broader use with the availability of high intensity X-ray beams at synchrotron radiation facilities, which enabled the measurement of (chemically)dilute samples.In addition to the experimental advances, it is also the progress in quantum chemical computations, which makes XES an intriguing tool for the study of the electronic structure of chemical compounds.
