    Community College students account for over 40% of all undergraduates in the US as well as the majority of minority students attending undergraduate courses. With issues in the geosciences such as; being the least diverse of all major STEM fields, an increasing number of retiring geoscientists, and a projected geoscience job growth not matching the number of geoscience graduates, the geoscience community needs to look at community colleges as a solution to these issues. A key factor for students entering and excelling in the geoscience is the opportunity for formative undergraduate field experiences. Formative field experiences go beyond one-day field excursions by incorporating field projects, interactive learning, and community building between participants in regions students are unfamiliar with. Unfortunately, these types of formative experiences often require logistics and resources that are not available or known to community college faculty. In order to build a framework for implementing formative field experiences by community colleges a two-week "field exchange" between two community colleges with different geological, social, and cultural settings was conducted. Supported with a supplemental grant from NSF, the "Border to Beltway" program provided 11 students from El Paso Community College and another 13 from Northern Virginia Community College with two one-week regional geology field trips: First, to West Texas in March 2014, and second, to the mid-Atlantic region in May 2014. Students were selected based on academic standing, non-traditional (minority, female, over 35, veteran) status, and interest in geology. Qualitative data collected from participants regarding the implementation of the field exchange include; student perception of geology before and after exchange, challenges students faced in the field or traveling for the first time, quantity and quality of projects given, and working with others from different backgrounds.

    We present the results of analysis of airborne pollution of green stands along the Minsk Beltway by components of deicing agents (chlorine). We used laser spectral analysis for rapid determination of chlorine. Comparison of the analysis results for accumulation of salt components in samples collected from trees along the Minsk Beltway with control samples showed that the chlorine content is 3.7-5.5 times higher than the control values. The degree of pollution depends on the position of the trees on the forest edge relative to the highway, which is confirmed by reliable correlation coefficients.

    @@ Despite the rhetoric of the past 18 months, few in the nation's capital really believed the Beltway lobbyist would disappear overnight just because a new President vowed to change business-as-usual in Washington and Congress heightened scrutiny. Yes, lobbyists now must heed stringent new disclosure rules; the gift-giving and golf outings have largely vanished. But the influence game rolls on in Obama's Washington.

    The problem of the reconstruction of the order of sequence elements in de novo sequencing of linear and cyclic peptides is reduced to the known turnpike and beltway problems, the latter of which having no polynomial time algorithm in the general case. A new simple approach is proposed to solve both problems. It is based on sequential removal of redundancy from the inputs. For the error-free inputs that simulate mass spectra with accuracy to [Formula: see text] Da, the size of inputs decreases from [Formula: see text] to [Formula: see text]. In this way, exhaustive search can be almost completely removed from the algorithms, and the number of steps to reconstruct a sequence is in direct ratio to the input size, [Formula: see text].

  11. Monitoring ground subsidence in urban environments: M-30 tunnels under Madrid City (Spain

    Full Text Available Big cities improvement usually requires the construction of large underground infrastructures, in order to ensure proper communication and optimize urban use. Monitoring ground subsidences is therefore one of the main challenges in changing urban environments. The "Madrid Río" project (2003-2008 is an effort to reclaim the riverfront land and improve the busy M-30 beltway that involved the construction of 7.93 km of tunnels underneath the southern center of Madrid City. This paper presents a remote-sensing approach to monitor ground subsidences induced by tunneling excavation.  The Persistent Scatterers Interferometry technique (PSI was used to estimate subsidence and displacement time series from Synthetic Aperture Radar images, acquired between August 2003 and April 2008 from ENVISAT.  Remote sensed results were compared to traditional extensometric measures, fitting adequately for selected sectors. Spatial analysis of displacements allowed evaluating impacts of tunneling on surrounding buildings and facilities, highlighting critical areas. The availability of a spatial distribution of displacements in a time series allowed analyzing longitudinal, cross-sectional and temporal dynamics. The main limitations during this work were the heterogeneous spatial distribution of Persistent Scatterers, the absence of measurement points in work areas, the threshold for velocity detection and low temporal resolution of ENVISAT images. Nevertheless, these limitations of DInSAR for monitoring infrastructures are overcome by actual satellites, being a complementary technique with an exceptional added value and temporal analysis capability.

    The US Department of Energy (DOE), through its contractor Martin Marietta Energy Systems, Inc., has constructed a storage facility, the Chestnut Ridge Borrow Area Waste Pile (CRBAWP), for mercury-contaminated soil excavated from the Oak Ridge Civic Center properties and the Oak Ridge Sewer Line Beltway. Excavation of the soil from the Civic Center began in September 1984 and was completed in early 1985. Similar soils from other areas of the city were added to the pile until 1987. Approximately 3000 yd{sup 3} are stored at the present time. An Interim Status RCRA permit was initially sought for this facility. Samples from the waste pile passed the Extraction Procedure Toxicity Test (EP Tox). The Tennessee Department of Health and Environment (now the Tennessee Department of Conservation-TDC) denied the permit based on their conclusion that the waste was not a RCRA-regulated waste. On September 25, 1990 the Toxicity Characteristic Leaching Procedure (TCLP) superseded the EP Tox test. TCLP tests are not proposed to satisfy a request by TDC and to make a final determination of the nature of the soils in order to close the CRBAWP as a solid waste disposal facility under Tennessee State rule 1200-1-7-.04. The objectives of this work are to summarize existing site information and detail actions necessary to sample and characterize soils from the waste pile as hazardous or nonhazardous per the Toxicity Characteristic Leaching Procedure (TCLP). Within the scope of this plan, a site investigation will be discussed; a field sampling plan will be described in terms of sampling locations, procedures, and quality assurance; and ancillary activities such as waste management, data management, and health and safety will be outlines. 15 refs., 7 figs., 2 tabs.

    Full Text Available La Cité internationale universitaire de Paris a été créée immédiatement après la première guerre mondiale pour favoriser les échanges et la rencontre entre les étudiants du monde entier. Conformément à la convention conclue en 1921 entre la Ville et l’Université de Paris, elle a été édifiée en bordure du parc Montsouris, sur des terrains situés à l’emplacement des anciennes fortifications de Thiers. Dès 1928, le rythme accéléré des constructions pose avec une certaine acuité le problème de l’extension du domaine. Celle-ci s’effectue par étapes durant l’Entre-deux-guerres, notamment aux dépens de la commune voisine de Gentilly. Mais dès le début des années cinquante, le projet de création du boulevard périphérique marque, pour la Cité internationale, la fin des possibilités d’agrandissement à partir du « site historique » du boulevard Jourdan. Aujourd’hui, la Cité se densifie et se développe « hors les murs ».The Cité internationale universitaire de Paris was created immediately after the First World War in order to encourage exchanges between university students from around the world. According to the 1921 convention established between the city and the University of Paris, the Cité was built along Montsouris Park, on lots previously occupied by the Thiers fortifications. Starting in 1928, the rapid development of the Cité made it necessary to extend the site. Between the two world wars, segments of the neighboring town of Gentilly were progressively annexed. But in the early 1950s, projects for the creation of a boulevard périphérique – beltway – made further extension impossible. Today, construction continues, both on-site and outside the walls of the historical Cité.

    Racist police brutality has been systemic in Prince George's County, Maryland. The victims include African Americans, the mentally challenged, and immigrant populations, creating a complex and uneven public health impact. Three threads characterize the social movements and intervention since 1970. First, a significant demographic shift occurred as African Americans became the majority population in the late 1980s when the first Black county executive was elected in 1994. Despite the change in political leadership, police brutality remained rampant. Lower-income households located close to the District of Columbia and "inside the beltway" experienced the most police brutality. In 2001, The Washington Post revealed that between 1990 and 2000, Prince George's police shot and killed more citizens per officer than any of the 50 largest city and county law enforcement agencies in the country, 84 % of whom were black. Of the 147 persons shot during the 1990s, 12 were mentally and/or emotionally disturbed; 6 of these shootings were fatal. Second, resistance to police brutality emerged in a variety of political formations throughout the period, especially in the late 1990s. Sustained community pressure prompted the Department of Justice (DOJ) to open a civil rights investigation of the police department in November 2000. To avoid a potential federal lawsuit, the county leadership negotiated a memorandum of agreement (MOA) with the DOJ to enact policy reforms, part of which called for supplementing the departmental mobile crisis team, comprised of mental health care professionals, to respond to all cases involving mentally challenged citizens. Third, the incomplete process of change subsequent to the ending of DOJ oversight suggests a continued challenge to social movements opposing police brutality. This study focuses on the effectiveness of the MOA along with the activism of the People's Coalition for Police Accountability (PCPA) in reforming a culture of police brutality

    The Lawrence Livermore National Laboratory (LLNL) Bioinformatics group has recently taken on a role in DTRA's Transformation Medical Technologies (TMT) program. The high-level goal of TMT is to accelerate the development of broad-spectrum countermeasures. To achieve this goal, there is a need to assess the genetic engineering (GE) approaches, potential application as well as detection and mitigation strategies. LLNL was tasked to coordinate a workshop to determine the scope of investments that DTRA should make to stay current with the rapid advances in genetic engineering technologies, so that accidental or malicious uses of GE technologies could be adequately detected and characterized. Attachment A is an earlier report produced by LLNL for TMT that provides some relevant background on Genetic Engineering detection. A workshop was held on September 23-24, 2010 in Springfield, Virginia. It was attended by a total of 55 people (see Attachment B). Twenty four (44%) of the attendees were academic researchers involved in GE or bioinformatics technology, 6 (11%) were from DTRA or the TMT program management, 7 (13%) were current TMT performers (including Jonathan Allen and Tom Slezak of LLNL who hosted the workshop), 11 (20%) were from other Federal agencies, and 7 (13%) were from industries that are involved in genetic engineering. Several attendees could be placed in multiple categories. There were 26 attendees (47%) who were from out of the DC area and received travel assistance through Invitational Travel Orders (ITOs). We note that this workshop could not have been as successful without the ability to invite experts from outside of the Beltway region. This workshop was an unclassified discussion of the science behind current genetic engineering capabilities. US citizenship was not required for attendance. While this may have limited some discussions concerning risk, we felt that it was more important for this first workshop to focus on the scientific state of
