Data processing activities at the MAGIC site

open11siMAGIC is a system of two imaging atmospheric Cherenkov telescopes located on the Canary Is- land of La Palma. The fast processing of the data at the observation site plays an essential part in the operation of the telescopes and has continuously improved since the beginning of the exper- iment. The on-site computing can be divided into three major contributions: the MAGIC online analysis (MOLA), providing preliminary real time analysis results; the on-site analysis (OSA), providing final data products at the end of each observation night; and the Data Check (DC), a daily check on the performance of the telescope’s subsystems and the quality control of the data observed during the previous night. We present the status of the system, including the latest upgrades and details on its performance.openFidalgo, David; Nievas-Rosillo, Miguel; Babic, Ana; Contreras, Jose-Luis; Doro, Michele; Godinovic, Nikola; Hrupec, Dario; Lorca, Alejandro; Moralejo, Abelardo; Satalecka, Konstancja; Will, MartinFidalgo, David; Nievas Rosillo, Miguel; Babic, Ana; Contreras, Jose Luis; Doro, Michele; Godinovic, Nikola; Hrupec, Dario; Lorca, Alejandro; Moralejo, Abelardo; Satalecka, Konstancja; Will, Marti

Extended duration lunar lander

Selenium Technologies has been conducting preliminary design work on a manned lunar lander for use in NASA's First Lunar Outpost (FLO) program. The resulting lander is designed to carry a crew of four astronauts to a prepositioned habitat on the lunar surface, remain on the lunar surface for up to 45 days while the crew is living in the habitat, then return the crew to earth via direct reentry and land recovery. Should the need arise, the crew can manually guide the lander to a safe lunar landing site, and live in the lander for up to ten days on the surface. Also, an abort to earth is available during any segment of the mission. The main propulsion system consists of a cluster of four modified Pratt and Whitney RL10 rocket engines that use liquid methane (LCH4) and liquid oxygen (LOX). Four engines are used to provide redundancy and a satisfactory engine out capability. Differences between the new propulsion system and the original system include slightly smaller engine size and lower thrust per engine, although specific impulse remains the same despite the smaller size. Concerns over nozzle ground clearance and engine reliability, as well as more information from Pratt and Whitney, brought about this change. The power system consists of a combination of regenerative fuel cells and solar arrays. While the lander is in flight to or from the moon, or during the lunar night, fuel cells provide all electrical power. During the lunar day, solar arrays are deployed to provide electrical power for the lander as well as electrolyzers, which separate some water back into hydrogen and oxygen for later use by the fuel cells. Total storage requirements for oxygen, hydrogen, and water are 61 kg, 551 kg, and 360 kg, respectively. The lander is a stage-and-a-half design with descent propellant, cargo, and landing gear contained in the descent stage, and the main propulsion system, ascent propellant, and crew module contained in the ascent stage. The primary structure for both stages is a truss, to which all tanks and components are attached. The crew module is a conical shape similar to that of the Apollo Command Module, but significantly larger with a height and maximum diameter of six meters

Fixed combinations of glaucoma medications

The first line treatment in the management of glaucoma is topical medical therapy. Many patients with glaucoma require multiple medications for adequate intraocular pressure control. For patients who need multi-dose regimens to control intraocular pressure, fixed combinations offer convenience, efficacy and safety. This review summarizes the role, efficacy, mechanism of action and indications for use of modern fixed combination of topical glaucoma medications. The review shows the advantages and disadvantages of a prescribing fixed combination in daily clinical practice
