Moving Full STEAM Ahead

How do you move a traditional elementary school to a hands-on, interactive, STEAM focused school? At Hampton Elementary Charter, we offer our students a variety of STEAM Stations each day to build career awareness in the areas of science, technology, engineering, arts, and math. This presentation will cover the successes, scheduling, surveys, decisions, and challenges of moving a school and doing what\u27s right for students. The primary audience is elementary and middle school teachers and administrators. Participants will be given the opportunity to share ideas, plans, questions, struggles, and opportunities for STEM and STEAM programs

Aerosols from biomass burning over the tropical South Atlantic region: Distributions and impacts

The NASA Global Tropospheric Experiment (GTE) Transport and Atmospheric Chemistry Near the Equator-Atlantic (TRACE A) expedition was conducted September 21 through October 26, 1992, to investigate factors responsible for creating the seasonal South Atlantic tropospheric ozone maximum. During these flights, fine aerosol (0.1-3.0 μm) number densities were observed to be enhanced roughly tenfold over remote regions of the tropical South Atlantic and greater over adjacent continental areas, relative to northern hemisphere observations and to measurements recorded in the same area during Ac wet season. Chemical and meteorological analyses as well as visual observations indicate that the primary source of these enhancements was biomass burning occurring within grassland regions of north central Brazil and southeastern Africa. These fires exhibited fine aerosol (N) emission ratios relative to CO (dN/dCO) of 22.5 ± 9.7 and 23.6 ± 15.1 cm-3 parts per billion by volume (ppbv)-1 over Brazil and Africa, respectively. Convection coupled with counterclockwise flow around the South Atlantic subtropical anticyclone subsequently distributed these aerosols throughout the remote South Atlantic troposphere. We calculate that dilute smoke from biomass burning produced an average tenfold enhancement in optical depth over the continental regions as well as a 50% increase in this parameter over the middle South Atlantic Ocean; these changes correspond to an estimated net cooling of up to 25 W m-2 and 2.4 W m-2 during clear-sky conditions over savannas and ocean respectively. Over the ocean our analyses suggest that modification of CCN concentrations within the persistent eastern Atlantic marine stratocumulus clouds by entrainment of subsiding haze layers could significantly increase cloud albedo resulting in an additional surface radiative cooling potentially greater in magnitude than that caused by direct extinction of solar radiation by the aerosol particles themselves

Airborne observations of the tropospheric CO2 distribution and its controlling factors over the South Pacific Basin

Highly precise measurements of CO2 mixing ratios were recorded aboard both the NASA DC-8 and P3-B aircraft during the Pacific Exploratory Mission-Tropics conducted in August-October 1996. Data were obtained at altitudes ranging from 0.1 to 12 km over a large portion of the South Pacific Basin representing the most geographically extensive CO2 data set recorded in this region. These data along with CO2 surface measurements from the National Oceanic and Atmospheric Administration/Climate Monitoring and Diagnostics Laboratory (NOAA/CMDL) and the National Institute of Water and Atmospheric Research (NIWA) were examined to establish vertical and meridional gradients. The CO2 spatial distribution in the southern hemisphere appeared to be largely determined by interhemispheric transport as air masses with depleted CO2 levels characteristic of northern hemispheric air were frequently observed south of the Intertropical Convergence Zone. However, regional processes also played a role in modulating background concentrations. Comparisons of CO2 with other trace gases indicated that CO2 values were influenced by continental sources. Large scale plumes from biomass burning activities produced enhanced CO2 mixing ratios within the lower to midtroposphere over portions of the remote Pacific. An apparent CO2 source was observed in the NOAA/ CMDL surface data between 15° N and 15° S and in the lower altitude flight data between 8° N and 8.5° S with a zone of intensity from 6.5° N to 1° S. Inferred from these data is the presence of a Southern Ocean sink from south of 15° S having two distinct zones seasonally out of phase with one another.

Mrub_3015 is orthologous to the b2757 gene found in \u3cem\u3eEscherichia coli\u3c/em\u3e coding for casD

This project is part of the Meiothermus ruber genome analysis project, which uses a collection of online bioinformatics tools to predict gene function. We investigated the biological function of the gene Mrub_3015, which we hypothesize is a component of the CRISPR-Cas prokaryotic defense system. We predict that Mrub_3015 (DNA coordinates 3055550...3056245) encodes the the CRISPR-associated protein cas5, which is integral in maintaining the crRNA-DNA structure, keeping the complex from base pairing with the target phage DNA. Our hypothesis is supported by identical hits for Mrub_3015 and b2527 to the KEGG, Pfam, TIGRfam, CDD and PDB databases as well as a low E-value for a pairwise NCBI BLAST comparison. Both protein products are predicted to be localized in the cytoplasm. Finally, both proteins share numerous highly conserved amino acids, when compared to the consensus sequence of Pfam domains PF09704, PF18019, and PF00270

The adoption of mobile technology as a tool for situational crime prevention in Kenya

Conference paper presented at IST-Africa 2014 conference- MauritiusThe adoption of mobile technology in crime prevention has substantially grown across the world. However, this is not the case in Kenya, because the public still have to go from one police station to another to report crimes and to receive general services from the police. The crime records are usually recorded manually in police Occurrence Book (OB) and therefore determining the accurate crime trends and rates of reported crimes has proved to be a major hurdle in crime prevention for the Kenya police. This study aimed at developing a mobile application that would aid the Kenyan public to report crimes to the nearest police station, receive alerts on new crime spot areas, query information about arrested individuals and encourage community policing. The study also involved the development of a back-end web-based prototype that incorporated a digitised OB and a criminal database. The mobile Android application was tested on various devices and the test results ascertained. The study revealed that most users would use the mobile-police application because of convenience, reduced fear of victimization and ease of use.The adoption of mobile technology in crime prevention has substantially grown across the world.

Criminal Sovereignty: Understanding North Korea\u27s Illicit International Activities

This monograph examines Office Number 39’s origins, organizational structure, and activities in order to develop a more calibrated strategy and policy to meet the North Korean challenge. This monograph focuses on Office Number 39\u27s key illicit activities— to include manufacture and distribution of illegal drugs, the counterfeiting of U.S. currency, and the manufacture and distribution of counterfeit cigarettes. Finally, as Kim Jong-Il grows frailer, assessing how his successor may continue or alter Office Number 39’s activities is also examined.https://press.armywarcollege.edu/monographs/1348/thumbnail.jp

Out of the Shadows: A Young Woman\u27s Journey from Hiding to Celebrating her Identity

In April 2019 the UK government reported that little progress had been made to remedy social outcomes inequality between Roma and the wider population, recommending further recognition of Roma, for example in census data, to enable identification of Roma, their needs, and how to meet those needs. In this article we present an account of one Roma woman’s journey from hiding her identity to celebrating it. We expose five critical incidents that challenge and mould her sense of identity and career aspiration, with insights into her hopes and dreams as she reflects upon the barriers she faces and attempts to overcome. The narrative enhances understanding of the intersection of experience and ethnic identity formation, Marcella’s (pseudonym) case study emerges verbatim through quotes; we do not alter or correct her English. In our exploration, we follow the six classical steps recommended in case study analysis (Yin, 2009) and ground some of the key analytical concepts in Goffman’s theories of stigma (1963) and theatrical performances in everyday life. We conclude by identifying key parallels in her experience, relevant regardless of socioeconomic status to further debate on the nature of internalised shame, stigma, and class
