Clara Barton
Get PDFStamp honors Clara Barton, founder of the American Red Cross. First day covers are envelopes or postcards with a stamp canceled on the first day the stamp is available for purchase and use. Often the postmark is a special pictorial cancellation indicating the city and date of issue. First day covers often include a cachet or illustration on the envelope that explains or compliments the stamp.https://digitalcommons.fairfield.edu/firstdaycover/1081/thumbnail.jp
Probing the Deep End of the Milky Way with New Oscillating Kepler Giants
Full text linkThe Kepler mission has been a success in both exoplanet search and stellar
physics studies. Red giants have actually been quite a highlight in the Kepler
scene. The Kepler long and almost continuous four-year observations allowed us
to detect oscillations in more than 15,000 red giants targeted by the mission.
However by looking at the power spectra of 45,000 stars classified as dwarfs
according to the Q1-16 Kepler star properties catalog, we detected red-giant
like oscillations in 850 stars. Even though this is a small addition to the
known red-giant sample, these misclassified stars represent a goldmine for
galactic archeology studies. Indeed they happen to be fainter (down to Kp~16)
and more distant (d>10kpc) than the known red giants, opening the possibility
to probe unknown regions of our Galaxy. The faintness of these red giants with
detected oscillations is very promising for detecting acoustic modes in red
giants observed with K2 and TESS. In this talk, I will present this new sample
of red giants with their revised stellar parameters derived from
asteroseismology. Then I will discuss about the distribution of their masses,
distances, and evolutionary states compared to the previously known sample of
red giants.Comment: 5 pages, 4 figures, Proceedings of the KASC9-TASC2 meetin
Drying/encapsulation of red wine to produce ingredientes for healthy foods
Get PDFEpidemiological evidence indicates that moderate consumption of red wine reducesthe incidence of coronary disease, atherosclerosis, and platelet aggregation. Wine is very rich in antioxidant compounds because of their phenolic components.However, many people for ethnic, social or religious reasons do not consume wine. Drying/encapsulation of red wine in the presence of adequate carbohydrates leads to water and more than 99% of alcohol removal; a glassy amorphous microstructure is obtained in which the wine's phenolic compounds are entrapped. The resulting product is a free flowing powder which could be used for the polyphenol enrichment of healthy foods and/or drink powders, as well as in the pharmaceutical industry. The wine industry may take advantage of the dried/encapsulated red wine using as a raw material red wines which have littlecommercial value for different reasons; i.e. poor quality due to raw material, unfavourable climatic conditions, or wines that suffered some alteration during the wine making process. Dry encapsulated wine may be a new alternative to red wines that cannot be sold as such for different reasons, and open new opportunities to diversify wine products.Fil: Alvarez Gaona, Izmari Jasel.

A plasma wakefield acceleration experiment using CLARA beam
Get PDFWe propose a Plasma Accelerator Research Station (PARS) based at proposed FEL
test facility CLARA (Compact Linear Accelerator for Research and Applications)
at Daresbury Laboratory. The idea is to use the relativistic electron beam from
CLARA, to investigate some key issues in electron beam transport and in
electron beam driven plasma wakefield acceleration, e.g. high gradient plasma
wakefield excitation driven by a relativistic electron bunch, two bunch
experiment for CLARA beam energy doubling, high transformer ratio, long bunch
self-modulation and some other advanced beam dynamics issues. This paper
presents the feasibility studies of electron beam transport to meet the
requirements for beam driven wakefield acceleration and presents the plasma
wakefield simulation results based on CLARA beam parameters. Other possible
experiments which can be conducted at the PARS beam line are also discussed

Comparison of Compression Schemes for CLARA
Full text linkCLARA (Compact Linear Advanced Research Accelerator)at Daresbury Laboratory
is proposed to be the UK's national FEL test facility. The accelerator will be
a ~250 MeV electron linac capable of producing short, high brightness electron
bunches. The machine comprises a 2.5cell RF photocathode gun, one 2 m and three
5 m normal conducting S-band (2998MHz) accelerating structures and a variable
magnetic compression chicane. CLARA will be used as a test bed for novel FEL
configurations. We present a comparison of acceleration and compression schemes
for the candidate machine layout.Comment: 3 pages, 5 figures, IPAC 201
