The Wide-field Spectroscopic Telescope (WST) Science White Paper

The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial concept as well as the corresponding science cases. WST will feature simultaneous operation of a large field-of-view (3 sq. degree), a high multiplex (20,000) multi-object spectrograph (MOS) and a giant 3x3 sq. arcmin integral field spectrograph (IFS). In scientific capability these requirements place WST far ahead of existing and planned facilities. Given the current investment in deep imaging surveys and noting the diagnostic power of spectroscopy, WST will fill a crucial gap in astronomical capability and work synergistically with future ground and space-based facilities. This white paper shows that WST can address outstanding scientific questions in the areas of cosmology; galaxy assembly, evolution, and enrichment, including our own Milky Way; origin of stars and planets; time domain and multi-messenger astrophysics. WST's uniquely rich dataset will deliver unforeseen discoveries in many of these areas. The WST Science Team (already including more than 500 scientists worldwide) is open to the all astronomical community.

TREATMENT OF HYPOTROPHIC HEMS

The problem  of treatment of patients with cicatricial defects of a skin concerns one of actual sections  of medicine. The new method of treatment of hypotrophic hems by a beam of the laser from  a long wave of 540  nanometers, duration of impulses 1 - 2 nanoseconds (a mode  of generation Q – sw),  energy  of an impulse  (50  - 150 мДж)  and  frequency of following of an impulse (1-4 Hz) is offered. Its influence on microcirculation of a bottom of a hem that promotes reduction of depth of a hem, improvement of its consistence is proved. At use of a method healing  passes  during  30 – 38 days,  with formation a normotrophic hem, skin color restoration
