Karl Maximovich

Carl Johann Maximovich (also Karl Ivanovich Maximovich, Russian: Карл Иванович Максимович; 1827 in Tula, Russia – 1891 in Saint Petersburg) was a Russian botanist. Maximovich spent most of his life studying the flora of the countries he had visited in the Far East, and naming many new species. He worked at the Saint Petersburg Botanical Gardens from 1852 as curator of the herbarium collection, becoming Director in 1869.

History

Born a Baltic-German, his name at birth was Karl Ivanovich Maksimovich, but he changed it to the German version of his name for his scientific work. He graduated from the institution which is now University of Tartu, Estonia in (1850), he was a pupil of Alexander G. von Bunge.

From 1853-1857 he traveled around the world. He travelled with another Baltic-German Leopold von Schrenck to the Amur region in eastern Asia. From 1859 to 1864 he also he visited China, Korea and Japan. He arrived in Japan in late 1860, initially basing his operations in Hakodate. He traveled extensively in southern Japan and for much of 1862 including the region of Yokohama and Mount Fuji, he ended that year in Nagasaki. He also explored much of Kyūshū.

Adrian Sînă

Adrian Claudiu Sînă (born April 18, 1977), better known as Adrian Sina or simply Adi Sina is a Romanian singer-songwriter, record producer, radio DJ and entertainer. He is best known for creating, producing and singing in the dance group Akcent and also for writing and producing mainstream hit songs for himself and other international artists. He started out as a disc jockey in the 1990s and then created a group with his fellow musician Ramona Barta. He came to prominence as a member of Akcent with the song "Ultima varǎ" (The Last Summer) in 1999. His group was joined by Marius Nedelcu, Sorin Brotnei and Mihai Gruia. Together they scored multiple number-one hits both in Romania and throughout Eastern Europe, especially in the mid-2000s. Their albums have been certified multi-Platinum by the Uniunea Naţională a Producătorilor de Fonograme din România and were sold in millions of copies worldwide. Their signature song was "Kylie", released in 2005.

In the early 2010s, Sina decided to release himself in a solo career and co-opted various recording artists on his side. He started his own record label, Premium Artist (formerly known as Sisterhoodlive Records) and he recorded some solo hits, such as "Hold On", "I Can't Live Without You" or "Angel". In 2011 he was also on the judging panel of the Romanian X Factor where he coached the over 25s. In the meantime, he managed to produce and write several number-one and top-ten hits for up-and-rising artists such as boyband Maxim and songstress Lidia Buble. He released a single, entitled "Arde ceva" (Something Burning) which was released in 2013. Songs "Lacrimi curg" and "Tu m-ai dat gata" followed, and his latest release is a collaboration with Cojo, namely "Zile bune, zile rele".

Roton

In theoretical physics, a roton is an elementary excitation, or quasiparticle, in superfluid helium-4. The dispersion relation of elementary excitations in this superfluid shows a linear increase from the origin, but exhibits first a maximum and then a minimum in energy as the momentum increases. Excitations with momenta in the linear region are called phonons; those with momenta close to the minimum are called rotons. Excitations with momenta near the maximum are sometimes called maxons.

The term "roton" is also used for the quantised eigenmode of a freely rotating molecule.

Models

Originally, the roton spectrum was phenomenologically introduced by Lev Landau. Currently there exist different models which try to explain the roton spectrum, with a different degree of success and fundamentality. The requirement for any model of such kind is that it must explain not only the shape of the spectrum itself but also other related observables, such as the speed of sound and structure factor of superfluid helium-4. Microwave and Bragg spectroscopy has been conducted on helium to study roton spectrum.

Music video

A music video or song video is a short film integrating a song and imagery, produced for promotional or artistic purposes. Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie in marketing campaigns that allow them to become more than just a song. Tie ins and merchandising could be used in toys are marketing campaigns for food and other products. Although the origins of music videos date back to musical short films that first appeared in the 1920s, they came into prominence in the 1980s when MTV based their format around the medium. Prior to the 1980s, these works were described by various terms including "illustrated song", "filmed insert", "promotional (promo) film", "promotional clip", "promotional video", "song video", "song clip" or "film clip". Since the creation and increased popularity of YouTube, mainstream artists now promote new music videos by releasing trailers of short promos on the site for their upcoming song and music video. Consequentially, YouTube has been converted into a social media platform for celebrities and artists to market themselves to their fans and audiences.
