Comcast, joined by Deputy Attorney General: Transportation, Real Estate & Construction Division for the Commonwealth of Virginia, Stephen A. Cobb and school administrators, recognized the students at a special event held Thursday, May 18, at the Virginia State Capitol. Fifty-nine recipients of the 2017 Virginia Leaders and Achievers® scholarships received $1,000 scholarships. Chrinique Christian, a senior at Matoaca High School in Chesterfield County was awarded a $10,000 Comcast Founders Scholarship – instituted in honor of Ralph J. Roberts, Founder and Chairman Emeritus of Comcast Corporation – for a total of $69,000 awarded this year to Virginia high school students. "It is an honor to be a part of an event that celebrates such exceptional young adults," said Cobb.  "These high school seniors have proven to be leaders in their communities, and the Comcast Leaders and Achievers Scholarship program is giving them the recognition they deserve. I look forward to following these students' successes in the years to come." "Our Leaders and Achievers Scholarship winners are committed to academic excellence and community service," said Mary McLaughlin, Senior Vice President of Comcast's Beltway Region. "We are honored to recognize their achievements, and are excited to support them as they continue their educational journeys." The Comcast Leaders and Achievers Scholarship Program provides scholarships to students who strive to achieve their full potential, who are catalysts for positive change in their communities, who are involved in their schools, and who serve as models for their fellow students. The philosophy behind the program is to give young people every opportunity to prepare for the future and to engage them in their communities. The program also demonstrates the importance of civic involvement, and the value placed on civic involvement by the business community. Since 2003, Comcast has awarded nearly $800,000 in Leaders & Achievers Scholarships to more than 760 students in Virginia.  This year, the program will award more than $2 million in scholarships to more than 2,000 students across the country to help them pursue higher education.  Visit here to learn more.

Since the large amplitude 2007 outburst which heated its accreting, pulsating white dwarf, the dwarf nova system GW Librae has been cooling to its quiescent temperature. Our Hubble Space Telescope ultraviolet spectra combined with ground-based optical coverage during the third and fourth year after outburst show that the fluxes and temperatures are still higher than quiescence (T = 19,700K and 17,300K versus 16,000K pre-outburst for a log g = 8.7 and d = 100pc). The K wd of 7.6 ± 0.8km s-1 determined from the C Iλ1463 absorption line, as well as the gravitational redshift implies a white dwarf mass of 0.79 ± 0.08 M . The widths of the UV lines imply a white dwarf rotation velocity v sin i of 40km s-1 and a spin period of 209s (for an inclination of 11deg and a white dwarf radius of 7 × 108cm). Light curves produced from the UV spectra in both years show a prominent multiplet near 290s, with higher amplitude in the UV compared to the optical, and increased amplitude in 2011 versus 2010. As the presence of this set of periods is intermittent in the optical on weekly timescales, it is unclear how this relates to the non-radial pulsations evident during quiescence. © 2012.

We report Galaxy Evolution Explorer NUV and optical follow-up observations of the cataclysmic variable V455 And at 3years past its large amplitude dwarf nova outburst. Orbital and superhump variations are evident in the NUV and optical light curves. We clearly detect the spin along with a photometric variation that we tentatively attribute to non-radial pulsations in the Discrete Fourier Transforms at both wavelengths. The increased amplitude of the spin and pulsation in the NUV versus the optical implies an origin near the white dwarf. The shorter pulsation period after outburst is indicative of a white dwarf that remains hotter than at quiescence. © © 2012. The American Astronomical Society. All rights reserved.

Hydrothermal reaction of copper nitrate and aromatic dicarboxylate precursors with the conformationally flexible and very long-spanning dipyridylamide ligand propane-1,3-diylbis(piperidine-4,1-diyl)bis(pyridin-4-ylmethanone) (4-ppbp) has generated three coordination polymers and a threaded-loop supramolecular complex. {[Cu(tere)(4-ppbp)(H2O)]·1.5H2O}n (1, tere = terephthalate) and {[Cu(iph)(4-ppbp)(H2O)]·2H2O}n (2, iph = isophthalate) both display slab motifs built from interdigitated (4,4) grid layers. {[Cu2(phda)(phdaH)2(4-ppbp)2]·6H2O}n (3, phda = 1,4-phenylenediacetate) possesses a 4-connected 658 cds network with self-penetration of 8-membered circuits. {[Cu2(phtH)2(4-ppbp)2(H2O)4](NO3)2·H2O}n (4, pht = phthalate) manifests ring-like dinuclear coordination complex cations with anionic phtH ligands projecting into supramolecular tubes with an inner diameter of approximately 12 Å. Dehydration and thermal degradation properties of these new materials are discussed. We also report the crystal structure of the recrystallized dipyridylamide, 4-ppbp·2H2O. © 2015 Elsevier B.V.

Hydrothermal reaction of zinc nitrate, aliphatic dicarboxylic acids, and the long-spanning hydrogen-bonding capable tethering ligand bis(4-pyridylmethyl)piperazine (4-bpmp) has produced seven coordination polymer solids that were characterized via single-crystal X-ray crystallography. [Zn(suc)(4-bpmp)(H2O)2]n (1, suc = succinate) shows 2D + 2D → 3D mutually inclined interpenetrated parallel coordination polymer layers with (4,4) grid topology. {[Zn2(dms)2(4-bpmp)]·2H2O}n (2, dms = 2,2-dimethylsuccinate) exhibits 1-D [Zn2(dms)2]n ribbons featuring {Zn2(OCO)2} dimeric units pillared into 2-D by 4-bpmp ligands. {[Zn(glu)(4-bpmp)]·6H2O}n (3, glu = glutarate) manifests a 3-fold interpenetrated 3-D 66 diamondoid topology with embedded C(10)A(4) water chains. [Zn(22dmg)(4-bpmp)]n (4, 22dmg = 2,2-dimethylglutarate) and [Zn(33dmg)(4-bpmp)]n (5, 33dmg = 3,3-dimethylglutarate) both display stacked zig-zag (4,4) grid layered topologies, and do not entrain any co-crystallized water molecules. Reduction of the steric hindrance by using 3-methylglutarate (3mg) afforded {[Zn(3mg)(4-bpmp)]·3H2O}n (6), which also displays a (4,4) grid topology, but with embedded R(4)A(2) water molecule hexamers connecting to three different layer motifs. [Zn(adp)(4-bpmp)]n (7, adp = adipate) possesses a system of 5-fold interpenetrated diamondoid nets. Thermal and luminescent properties of these materials are discussed herein. © 2014 Elsevier B.V.

The article describes a live e-mission activity when year 10 students formed an Emergency Response Team to ensure the safety of the residents of Montserrat as they face a volcanic eruption and a hurricane. The e-mission activity from the National Space Center in Leicester involves students working together as an emergency response team to ensure the safety of the islanders of Montserrat. The activity supported a year 10 unit of work looking at the impacts of volcanic eruptions and how they are monitored. The evacuation team had a large map of the island showing the towns and roads. They had to use information from the mission commander at the Space Center, via the webcam, and input from the other teams to decide which parts of the island were in danger and where the residents should be evacuated to.

In the title co-crystal, C25H32N4O2C14H10O5, molecules are connected into supramolecular chains aligned along [102] by O-H⋯N hydrogen bonding. These aggregate into supramolecular layers oriented parallel to (20-1) by C-H⋯O interactions. These layers then stack in an ABAB pattern along the c crystal direction to give the full three-dimensional crystal structure. The central chain in the dipyridylamide has an anti-anti conformation. The dihedral angle between the aromatic ring planes is 29.96(3)°. Disorder is noted in some of the residues in the structure and this is manifested in two coplanar dispositions of one statistically disordered carboxylic acid group.
