Galileovo delo Dialog o dveh glavnih sistemih sveta, ptolemajskem in kopernikanskem iz leta 1632, »kopernikanski manifest« in eno najslavnejših del iz zgodovine znanosti, je pomemben mejnik v zgodovini človeške misli. V njem trije sogovorniki, pronicljivi Salviati, pošteni Sagredo in preprosti aristotelik Simplicij v štiridnevnem pogovoru razpravljajo o obeh sistemih sveta ter pretresajo njune prednosti in slabosti. Galileo v Dialogu obravnava tri glavne teme. Najprej skuša pokazati, da na Zemlji izvedljivi poskusi ne morejo pokazati niti njene negibnosti niti njenega gibanja. Nato preučuje nebesne pojave (Sončeve pege, gore na Luni ...), da bi utrdil »kopernikansko hipotezo«. In nazadnje predlaga »duhovito domislico« o plimovanju morja, ki ga je mogoče pojasniti, samo če dopustimo, da se Zemlja giblje.

Titan, the largest of Saturn's moons, shares remarkable similarities with Earth. Its thick atmosphere is composed primarily of nitrogen; it features the most complex organic chemistry known outside of Earth and, uniquely, hosts an analog to Earth's hydrological cycle, with methane forming clouds, rain and seas. Using the latest data from the ongoing Cassini-Huygens missions, laboratory measurements and numerical simulations, this comprehensive reference examines the physical processes that shape Titan's fascinating atmospheric structure and chemistry, weather, climate, circulation and surface geology. The text also surveys leading theories about Titan's origin and evolution, and assesses their implications for understanding the formation of other complex planetary bodies. Written by an international team of specialists, chapters offer detailed, comparative treatments of Titan's known properties and discuss the latest frontiers in the Cassini-Huygens mission, offering students and researchers of planetary science, geology, astronomy and space physics an insightful reference and guide.

In Global Navigation Satellite Systems (GNSS), the on-board clocks are a key component from which timing and navigation signals are generated. This thesis reviews the performance of the first Passive Hydrogen Maser (PHM) launched by the Galileo system in 2008; and demonstrates how the new PHM can be consider as the best clock in space, pushing the physical clock error contribution below the noise floor of geodetic time transfer capabilities. Furthermore, overall GNSS clock peformance is reviewed

The search for knowledge on cellular and molecular mechanisms involved in skeletal muscle mass homeostasis and regeneration is an exciting scientific area and extremely important to develop therapeutic strategies for neuromuscular disorders and conditions related to muscle wasting. The mechanisms involved in the regulation of skeletal muscle mass and regeneration consist of molecular signaling pathways modulating protein synthesis and degradation, bioenergetics alterations and preserved function of muscle stem cells. In the last years, different kinds of stem cells has been reported to be localized into skeletal muscle (satellite cells, mesoangioblasts, progenitor interstitial cells and others) or migrate from non-muscle sites, such as bone marrow, to muscle tissue in response to injury. In addition, myogenic progenitor cells are also activated in skeletal muscle wasting disorders. The goal of this research topic is to highlight the available knowledge regarding skeletal muscle and stem cell biology in the context of both physiological and pathological conditions. Our purpose herein is to facilitate better dissemination of research into skeletal muscle physiology field.
