Long-Term Storage Considerations for Spacecraft Lubricants

Inertial Energy Storage for Spacecraft

The feasibility of inertial energy storage in a spacecraft power system is evaluated on the basis of a conceptual integrated design that encompasses a composite rotor, magnetic suspension, and a permanent magnet (PM) motorlgenerator for a 3-kW orbital average payload at a bus distribution voltage of 250 volts dc. The conceptual design, which evolved at the Goddard Space Flight Center (GSFC), is...

How Long Is Long-Term Data Storage?

In the context of archiving of physical documents, long-term storage has long been accepted to mean centuries. Digital documents are much more ephemeral, so archivists should be aware of the inherent limitations of the technologies available for preservation of digital data. This paper compiles the results of several studies on this subject, in addition to presenting new findings on what can be...

Short-Long-Term Memory Interaction with Underlearned Long-Term Storage.

Platelet Factor 3 Based-clotting Time Assay as a Quality Marker for Long-term Storage of Platelet Concentrates

Background: Platelets rapidly lose their qualities usually after 5 day of storage. Different standard methods have been recommended to check the quality of platelets during storage which some of them show better correlation with other quality markers during storage. The purpose of this study was to demonstrate if platelet factor 3 (PF3) assay could be an indicator of storage lesion and provide ...

PDE5 inhibitors: considerations for preference and long-term adherence.

INTRODUCTION Erectile dysfunction (ED) is a highly prevalent condition affecting nearly one in five men worldwide. The advent of phosphodiesterase type 5 inhibitors (PDE5i) has revolutionised the ED treatment landscape and provided effective, minimally invasive therapies to restore male sexual function. MATERIALS AND METHODS A pubmed search was performed of all English language articles from ...
