    Photocopy of an advertising flier promoting a concert by the Washington, D.C. punk band, Rites Of Spring. The concert occurred on December 15, 1984 at Food For Thought, a restaurant/concert venue in Washington, D.C. The other bands on the bill were the Washington, D.C. punk bands Gray Matter and Grand Mal. The photocopy was made by D.C. artist, author, and musician Sharon Cheslow as part of the research for "Banned in D.C.," a book she co-authored with Cynthia Connolly and Leslie Clague

    Flier advertising State of Alert (S.O.A) concert at d.c. space, with Untouchables, Minor Threat, Type-O, Nurses, Fluffy Pig, and Wiggly Mittens, Washington, D.C., December 17-18, 1980. These concerts were also known as the Unheard Music festival. Within a year, S.O.A. vocalist Henry Garfield joined the influential California hardcore punk Black Flag and changed his last name to Rollins. He went on to a successful career as a musician, author, actor, television host and more. Guitarist Michael Hampton went on to play in the notable D.C. bands The Faith, Embrace, The Snakes, and Manifesto. These concerts were some of the first performances by Minor Threat. Fronted by vocalist Ian MacKaye (who went on to play in the bands Fugazi, Embrace, and The Evens), Minor Threat went on to become the definitive D.C. hardcore punk band

    Flood defenses Washington D.C.

    The United States of America have a safety standard for flood protection of 1/100 year. However the flood protections in the Washington D.C. do not comply with this requirement. During this study the levees in Washington D.C. area were analysed and it was found, that in order to comply with the 1/100 safety standard the levees in the NationalMall needs to be heighten by 0.5mand those near the Anacostia river by 1.5m. The safety standard of 1/100 imposed in the United States of America is not based on exact calculation, therefore another design method was applied, which uses an optimal safety level based on the damage cost of floods and investment cost of flood protections.The calculation of the optimal return period was based on the ’Standaardmethode 2017’ and it was found that the optimal return period at the NationalMall levee is 1/263 years. At the southern bank of the Anacostia river this optimal return period is 1/373 year. With these return periods new levees were designed in order to ensure the safety of the area of Washington D.C. There were two new levees needed around the National mall. The first was situated north of the Lincolnmemory along the Potomac river and the second replaces the temporary flood defence by the 2nd street SW and had an L-shape facing the Potomac river. The Anacostia levee was stretched on the East side in order to comply with the new 1/373 year safety standard. The old and new National mall levees needed a height of 3.5 m and those by the Anacostia needed a height of 8.5 m. It is important to take cautionwith these new levees as some houses needed to be removed. An attempt was made at modelling the above mentioned floods in ADCIRC to improve the accuracy of the design water levels and to verify the final design. However, the model showed instabilities, preventing the results from being used.Explanations for these instabilities are the incoming water not being properly ramped up, the large vertical gradients in shallow areas and the upstream and downstream boundaries being too close to each other.MP278Multidisciplinary Projec

    El carácter defensivo de Xochicalco (650-1100 d.C.). 43. Arqueología

    A partir del debilitamiento teotihuacano, alrededor del año 650 d.C., surgen varios sitios con características defensivas en toda Mesoamérica. Se ha considerado a Xochicalco como una ciudad de orden defensivo y militar, desde la primera vez que se visitó en 1777, dada la presencia de murallas, bastiones y fosos. Investigaciones recientes —aunadas a trabajos anteriores en una de las entradas principales a Xochicalco— ratifican que entre los años 650 y 1100 d.C., estos elementos arquitectónicos tuvieron una función defensiva, a pesar de que involucran diferentes áreas de actividad, incluyendo las de tipo ritual. La ciudad tenía todo previsto para efectuar la defensa ante un asalto, un ataque frontal o por los costados, la invasión, la escalada, el confinamiento, todo menos un conflicto interno que le llevaría a su total abandono

    A progression of strong bands in the 900--2200 \wn~ region are observed in the infrared laser photodissociation spectrum of \chem{Ar_3H^+}.\footnote{D.C. McDonald II, D.T. Mauney, D. Leicht, J.H. Marks, J.A. Tan, J.-L. Kuo, and M.A. Duncan, J. Chem. Phys. 145, 231101 (2016).} In this talk, computational studies were conducted to examine the structures, binding energies, and infrared spectra for \chem{Ar_nH^+} (n=2--3). We found that the minimum structure for \chem{Ar_2H^+} is linear and centrosymmetric, while \chem{Ar_3H^+} can be either T-shaped or linear.\footnote{J.A. Tan and J.-L. Kuo, J. Phys. Chem. A 124, 7726–7734 (2020).} A series of potential energy surfaces at the CCSD(T)/aug-cc-pVTZ level of theory and basis set was constructed and used for the calculation of anharmonic spectrum using discrete variable representation (DVR).\footnote{J.C. Light, I.P. Hamilton, and J. V. Lill, J. Chem. Phys. 82, 1400 (1985).} Anharmonic theory can reproduce the observed strong bands, which were associated with the core \chem{Ar_2H^+} ion. These bands are assigned as combination bands of the asymmetric Ar-\chem{H^+} stretch with multiple quanta of the symmetric Ar-\chem{H^+} stretch.Made available in DSpace on 2021-09-24T21:08:45Z (GMT).
