Mariner 6 and 7 pictures show that craters are the dominant landform on Mars and that their occurrence is not correlated uniquely with latitude, elevation, or albedo markings. Two distinct morphological classes are recognized: small bowl-shaped and large flat-bottomed. The former show little evidence of modifications, whereas the latter appear generally more modified than hmar upland craters of...

INTRODUCTION The Molecular Adsorbent Recycling System (MARS) is used to treat patients with liver failure. Observational data suggest that citrate anticoagulation during MARS is feasible. Comparative studies on the optimal anticoagulation regimen during MARS are lacking. The aim of the current study was to evaluate two heparin-free anticoagulation regimens. METHODS We performed a prospective ...

Providing a reliable service in a continuously running real-time system is problematic. MARS (MAintainable Real-time System) o ers correct and timely responsiveness by design and ease of maintenance by design of a new fault-tolerant distributed real-time system with active redundancy. Several unconventional techniques are implemented in the operating system of MARS. It is based on a time rigid ...

Posthepatectomy liver failure (PHLF) represents the single most important cause of postoperative mortality after major liver resection, yet no effective treatment option is available. Extracorporeal liver support devices might be helpful, but systematic studies are lacking. Accordingly, we aimed to assess the safety and feasibility of the Molecular Adsorbent Recirculating System (MARS) in patie...

Among the worlds beyond Earth potentially accessible to man in the foreseeable future, only the planet Mars falls within the known parameters of life. Given the present and potential range of human technological capabilities, in the relatively near future it may be possible to profoundly modify environmental and ecological conditions on Mars by a process that has come to be known as terraformat...

The serm morphological, spin-axial, polar antipodal congruencies of Earth, Mars, Venus, extremely unlikely to have happened randomly, are concentric with hemispheric dichotomies, consistent with super huge impact tectonogenesis, otherwise inexplicable. The hemispheric dichotomies of Mars and Venus must be the effects of super huge impacts centred at what more or less were during Johnstonian imp...

The Mars Pathfinder, Mars Surveyor ’98, and Mars Surveyor ’01 lander designs all utilize charged coupled device (CCD)-based cameras to conduct scientific investigations, assist with navigation of surface rovers and/or confirm sample acquisition and delivery by robotic arms (RAs). The extreme temperature and pressure environment of the Martian surface, the vibration and shock experienced during ...

Introduction: The detection of methane in the Martian atmosphere (1-4) and the probability of the existence of liquid water during the early history of Mars (5-10) prompted enthusiasm about plausible life forms on Mars. The half-life of methane in a planetary atmosphere is about 300 years (11), so in order to be detected on Mars, methane would need to be replenished continuously. Several potent...
