STS-3 medical report
The medical operations report for STS-3, which includes a review of the health of the crew before, during, and immediately after the third Shuttle orbital flight is presented. Areas reviewed include: health evaluation, medical debriefing of crewmembers, health stabilization program, medical training, medical 'kit' carried in flight, tests and countermeasures for space motion sickness, cardiovascular profile, biochemistry and endocrinology results, hematology and immunology analyses, medical microbiology, food and nutrition, potable water, shuttle toxicology, radiological health, and cabin acoustic noise. Environmental effects of shuttle launch and landing medical information management, and management, planning, and implementation of the medical program are also dicussed
Shuttle OFT medical report: Summary of medical results from STS-1, STS-2, STS-3, and STS-4
The medical operations for the orbital test flights which includes a review of the health of the crews before, during, and immediately after the four shuttle orbital flights are reported. Health evaluation, health stabilization program, medical training, medical "kit" carried in flight, tests and countermeasures for space motion sickness, cardiovascular, biochemistry and endocrinology results, hematology and immunology analyses, medical microbiology, food and nutrition, potable water, Shuttle toxicology, radiological health, and cabin acoustical noise are reviewed. Information on environmental effects of Shuttle launch and landing, medical information management, and management, planning, and implementation of the medical program are included
Social change, migration and pregnancy intervals
Maternity histories from residents of a Pacific Island society, Tokelau, and migrants to New Zealand, are analysed using life table techniques. Inter-cohort differentials in patterns of family formation were found in the total Tokelau-origin population. The process of accelerated timing and spacing of pregnancies was more pronounced among migrants who tended to marry later, be pregnant at marriage, have shorter inter-pregnancy intervals at lower parities and to show evidence of family limitation occurring at higher parities. These results point to the significance of changing patterns of social control on strategies of family building
Proton radiation damage study of the next generation of swept charge devices
The first generation of Swept Charge Device (SCD) the e2v technologies plc CCD54 was used in the Demonstration of a Compact Imaging X-ray Spectrometer (D-CIXS) launched in 2003 and again in the Chandrayaan-1 X-ray Spectrometer (C1XS) instrument currently in orbit around the Moon. The main source of decreased energy resolution in both cases is proton damage, from trapped and solar protons respectively. This paper presents the results from an experimental study to evaluate the performance of the next generation of SCD the CCD234 and CCD236 irradiated with a 10 MeV equivalent proton fluence of 3.0?108 protons.cm-2, demonstrating the factor of two increase in radiation hardness when compared to the CCD54. In particular the increased dark current, decrease in energy resolution and the degradation of charge transfer efficiency (CTE) are described
Response of Thompson Seedless grapes to prebloom thinning
Paired treatments with and without application of GA at bloom were applied to Thompson Seedless vines that were
cluster-thinned at prebloom, and berrythinned at shatter,
cluster-thinned and berry-thinned at prebloom, or
cluster-thinned and berry-thinned at shatter stage following bloom.
Unsprayed clusters from vines that were cluster-thinned at prebloom or cluster- and berrythinned at prebloom stage were very compact. All combinations of thinning that included applications of GA at bloom produced clusters that were looser than the corresponding unsprayed clusters. GA increased berry size, and clusters that received GA usually had fewer shot berries than did corresponding unsprayed clusters.
Prebloom thinning increased the number of berries per cm. of lateral, but applications of GA at bloom greatly decreased the amount of set.
A reduction of flower shatter occurred as a results of prebloom thinning
Overview on sugar metabolism and its control in Lactococcus lactis - The input from in vivo NMR
The wide application of lactic acid bacteria in the production of fermented foods depends to a great extent on the unique features of sugar metabolism in these organisms. The relative metabolic simplicity and the availability of genetic tools made Lactococcus lactis the organism of choice to gain insight into metabolic and regulatory networks. In vivo nuclear magnetic resonance has proven a very useful technique to monitor non-invasively the dynamics of intracellular metabolite and co-factor pools following a glucose pulse. Examples of the application of this methodology to identify metabolic bottlenecks and regulatory sites are presented. The use of this information to direct metabolic engineering strategies is illustrated. (c) 2005 Federation of European Microbiological Societies. Published by Elsevier B.V. All rights reserved

A comparative study of proton radiation damage in p- and n-channel
It has been demonstrated that p-channel charge coupled devices (CCDs) are more radiation hard than conventional n-channel devices as they are not affected by the dominant electron trapping caused by the displacement damage defect the E-centre (phosphorus-vacancy). This paper presents a summary of the results from a comparative study of n-channel and p-channel CCDs each type operated under the same conditions. The CCD tested is the e2v technologies plc CCD47-20, a 1024 ? 1024 frame transfer device with a split output register, fabricated using the same mask to form n-channel and
p-channel devices. The p-channel devices were irradiated to a 10 MeV equivalent proton fluence of 4.07?1010 protons.cm-2 and 1.35?1011 protons.cm-2, an n-channel CCD was irradiated to a 10 MeV equivalent proton fluence of 1.68?109 protons.cm-2, however due to time constraints the n-channel device was not characterised, n-channel comparisons are instead made using a CCD02. As expected the p-channel CCD demonstrated improved radiation tolerance when compared to the n-channel CCD, at -90 ?C there is an approximate ×7 and ×15 improvement in tolerance to radiation induced parallel and serial CTI respectively for equivalent pixel geometries
Growing Scale-Free Networks with Tunable Clustering
We extend the standard scale-free network model to include a ``triad
formation step''. We analyze the geometric properties of networks generated by
this algorithm both analytically and by numerical calculations, and find that
our model possesses the same characteristics as the standard scale-free
networks like the power-law degree distribution and the small average geodesic
length, but with the high-clustering at the same time. In our model, the
clustering coefficient is also shown to be tunable simply by changing a control
parameter - the average number of triad formation trials per time step.Comment: Accepted for publication in Phys. Rev.
