Spring 2018 - UHCL Physics and Space Science Seminar Series
Our distinguished Physics Lecture Series takes place once per year during the spring semester. World Renowned Scientists speak on a variety of Physics and Space Science topics. These talks, aimed at a general audience, are appropriate for anyone from high-school students to practicing scientists. These talks are free and open to the public. Our spring seminar series exposes a general audience to ongoing research in Physics and Space Science. This seminar takes place every week during the spring semester, in conjunction with the Research Project and Seminar class (PHYS 6838) and the Modern Physics Research Seminar class (PHYS 4732). These talks are open to the public. Continuing education credits are available.
To register, visit our online registration (under Professional Development click the "Physics Seminar Series" link). For assistance,
call the Center for Educational Programs at 281-283-3530. If you are not pursuing
a credit, you are still welcome to attend at no charge. All talks take place Monday
evenings in SSCB 1100 they start at 7 p.m.
University credit is available for the series in two ways. Non-physics majors can receive class credit by signing up for PHYS 4732. Students can earn continuing education certificates through this series. The cost is $15 per individual seminar, $40 for any three seminars, or $99 for the entire series.

Biologic Modifiers of Radioresponse
Heath Skinner, Assistant Professor of Radiation Oncology, The University of Texas MD Anderson Cancer Center
The most developed of these being proton-based radiation, although other heavy ion therapies, such as carbon and helium are being developed. While technologic advances in the therapeutic delivery of radiotherapy have been dramatic over the past several decades, biologic modulators of radioresponse are comparatively underdeveloped. There is currently only 1 FDA-approved biologic agent to improve tumor response to radiation. Similarly, there is only 1 radioprotector in clinical use. Improved understanding of radioresponse is both key to improving the therapeutic use of radiation to treat malignancy as well as to potentially mitigate damage due to long term occupational exposure.
In this presentation, I will give a brief overview of the utilization of therapeutic radiotherapy followed by a discussion of the current development of novel biologic radiomodulators.

The Weather on the Moon and the Mystery of the Swirls
Georgiana Kramer, Staff Scientist, LPI
The lunar swirls, however, break these rules.
In addition to their sinuous shapes, lunar swirls are optically bright, spectrally immature, and associated with magnetic anomalies (the Moon has no global magnetic field).
There are two competing hypotheses to explain the lunar swirls:
Using orbital spectroscopic data from Clementine, Kaguya, and Chandrayaan-1, Dr. Georgiana Kramer demonstrated that: 1) despite having spectral characteristics of being immature, the lunar swirls are not freshly exposed surfaces, 2) swirl surfaces are regions of retarded weathering while regions adjacent to swirls experience accelerated weathering, and 3) maps of OH abundance show the lunar swirls are depleted in OH relative to their surroundings. These conclusions support the hypothesis that the magnetic anomalies redirect solar wind ions, thereby slowing the process that darkens the lunar soil.
Studying lunar swirls is more than just studying a lunar phenomenon: the swirls provide a laboratory to study the solar wind, space weathering, and complex electromagnetic interactions in the Solar System.
Spacecraft Charging: Hazard Causes, Hazard Effects, Hazard Controls
Steven Koontz, ISS System Manager for Space Environments
In this paper ISS charging measurements with numerical modeling of ISS charging processes
are compared. ISS is a large metallic structure and flight through the geomagnetic
field at orbital speed dominates ISS charging. Collection of ionospheric electrons
by the large 160V PV arrays is the next largest contributor. Charging by auroral electrons
is detectable but makes a relatively minor contributions. Finally we report the observation
of short duration (~ 1 sec) rapid charging peaks associated with shunt/un-shunt operations
of the 160V PV arrays, a phenomena not predicted before flight. ISS spacecraft charging
environments are radically different from those encountered at higher altitudes in
Earth’s magnetosphere and in cis-Lunar space. A brief review of those charging environments
and an assessment of the applicability of ISS spacecraft charging management and experience
to future human spaceflight programs beyond LEO is presented.
