Shuttle Electrical Power Analysis Program (SEPAP); single string circuit analysis report
An evaluation is reported of the data obtained from an analysis of the distribution network characteristics of the shuttle during a spacelab mission. A description of the approach utilized in the development of the computer program and data base is provided and conclusions are drawn from the analysis of the data. Data sheets are provided for information to support the detailed discussion on each computer run

Positioning the Library Talk as a Form of Informal Public Communication of Science
One way of increasing the public’s engagement with science is informal science communication, or science encounters that are informal, voluntary and unstructured. This paper focuses specifically on one such type, the library talk. It examines the motivations for presenting such talks and questions whether these talks serve as PUS or PES(T) experiences

Quantification of apolipoprotein E receptors in human brain-derived cell lines by real-time polymerase chain reaction
Apolipoprotein (apo) E4 is a risk factor for Alzheimer's disease (AD) and other neurodegenerative diseases, compared to wild-type apoE3. The mechanism(s) is unknown. One possibility, demonstrated in peripheral tissue cell lines, is that apoE stimulates nitric oxide synthase (NOS) via a receptor-dependent signalling pathway and that apoE4 generates inappropriate amounts of nitric oxide (NO) compared to apoE3. Prior to biochemical investigations, we have quantified the expression of several candidate receptor genes, including low-density lipoprotein-receptor (LDL-r) family members and scavenger receptor class B, types I and II (SR-BI/II), as well as the three NOS isoenzymes and protein kinase B (Akt), in 38 human cell lines, of which 12 derive from brain. Expression of apoE receptor 2 (apoER2), a known signalling receptor in brain, was readily detected in SH-SY-5Y and CCF-STTG1 cells, common models of neurons and astrocytes, respectively, and was highest in H4 neuroglioma, NT-2 precursor cells and IMR-32 neuroblastoma cells. Transcripts of the other lipoprotein receptors were widely, but variably, distributed across the different cell types. Of particular note was the predominant expression of SR-BII over SR-BI in many of the brain-derived cells. As the C-terminus of SR-BII, like apoER2, contains potential SH3 signalling motifs, we suggest that in brain SR-BII functions as a signal transducer receptor. (c) 2004 Elsevier Inc.

The Pursuit of Advil and Blow Pops
“Excuse me sir, where’s the Advil?” I ask politely as I walk, for the first time, into the Quik Mart across the street from the Colonial Hall apartments.
“Over there.” A middle-aged Indian man declares, apparently suspicious of my request to alleviate my cramps.
I smile back anyway, hoping that his face is permanently in a suspicious glance that makes me uncomfortable to go anywhere but the aisle in front of him. [excerpt
Avionics test bed development plan
The plan is for a facility for the early investigation and evaluation of new concepts for the control of large space structures, orbiter attached flex body experiments, and orbiter enhancements. This plan outlines a distributed data processing facility that will utilize the current JSC laboratory resources for the test bed development. The future studies required for implementation, the management system for project control, and the baseline system configuration are described
Avionics test bed development plan
A development plan for a proposed avionics test bed facility for the early investigation and evaluation of new concepts for the control of large space structures, orbiter attached flex body experiments, and orbiter enhancements is presented. A distributed data processing facility that utilizes the current laboratory resources for the test bed development is outlined. Future studies required for implementation, the management system for project control, and the baseline system configuration are defined. A background analysis of the specific hardware system for the preliminary baseline avionics test bed system is included
