The Shuttle Orbital Maneuvering System P-V-T Propellant Quantity Gaging Accuracy and Leak Detection Allowance for Four Instrumentation Conditions [PDF]

open access: yes
The shuttle orbital maneuvering system (OMS) pressure-volume-temperature (P-V-T) propellant gaging module computes the quantity of usable OMS propellant remaining based on the real gas P-V-T relationship for the propellant tank pressurant, helium.

First Report of Nephrocalcinosis in Aquacultured Brazilian Sardine (Sardinella brasiliensis Steindachner, 1879)

open access: yesJournal of Fish Diseases, Volume 49, Issue 4, April 2026.
ABSTRACT While nephrocalcinosis (kidney stones) is uncommon in wild teleost fish, various environmental and nutritional factors could lead to its occurrence in aquacultured fish. This study presents the first documented case of kidney stones in aquacultured Brazilian sardine (Sardinella brasiliensis). During necropsy, eighteen hard, white kidney stones

Återvändo : Om kriget, om flykten och om att återvända

open access: yes, 2016
Under 1990-talet lämnade 2,2 miljoner människor sina hem på grund av Bosnienkriget. En stor andel flydde utomlands, många till Sverige men en stor andel blev också internflyktingar inom landets gränser. Över tjugo år har gått sedan kriget officiellt avslutats och en del av de som tidigare flytt har nu återvänt till det som kom att bli efterkrigstidens,

Generalized OM-Bisimulation

open access: yesInformation and Computation, 1995
AbstractHistory preserving bisimilarity and maximality preserving bisimilarity take full account of the interplay between causality and branching, and they are congruences w.r.t. action refinement for suitable classes of Petri nets. But even for finite safe Petri nets they are based on possibly infinite transition systems, and it is not obvious how to ...

Clonal Stabilization Reveals a DAO/3MST‐Expressing MDCK Subpopulation With Robust d‐Cysteine‐Mediated H2S Production

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
A subpopulation of MDCK (NBL‐2) cells, an epithelial cell line derived from the normal kidney, expresses DAO and 3MST. The DAO/3MST‐expressing cells are progressively eliminated during passaging; however, clonal isolation enables the establishment of sublines that maintain stable H2S production. Clonal cells co‐expressing DAO and 3MST therefore provide

Error Analysis of the Shuttle Orbital Maneuvering System P-V-T Propellant Gaging Module. Mission Planning, Mission Analysis and Software Formulation [PDF]

open access: yes
An investigation of the shuttle orbital maneuvering system (OMS) pressure-volume-temperature (P-V-T) propellant gaging module has revealed that the gaging errors due to the combined effects of random instrumentation measurement errors, propellant loading

Uprated OMS Engine Status-Sea Level Testing Results [PDF]

open access: yes
The current Space Shuttle Orbital Maneuvering Engine (OME) is pressure fed, utilizing storable propellants. Performance uprating of this engine, through the use of a gas generator driven turbopump to increase operating pressure, is being pursued by the ...

Berättelser om skolan, berättelser om kön

open access: yesKulturella Perspektiv – Svensk etnologisk tidskrift, 1998
The fact that boys often take more place in school, and therefore get more of the teachers' time, is well documented. This article deals with questions concerning the meaning of physical and verbal space in the classroom situation. What does it mean for the construction of gender?

Drømmen om byen, drømmen om vesten - drømmen om "Eldorado"

open access: yes, 2006
Avhandlingen er basert på feltarbeid utført i Agadir, Marokko fra 1. desember 2004 til 1. juni 2005. Hovedtema er arbeidsledighet i den tredje verden, og feltets målgruppe er unge arbeidsløse. Marokkos innbyggertall oversteg 33 millioner i 2005, hvorav 60 % var under 25 år, definert som et ”ungdomsproblem”.
