The final product is Cyberchase Fractions Quest—a math game based on the storyline of PBS children's television series, Cyberchase. In the game, students in grades 3 and 4 will apply learning fractions within three contexts: areas and regions (such as shapes), sets (groups of objects), and on a number line. The game will identify specific areas where students struggle and will introduce challeng ...

With this Phase I funding, the project team will develop and test a prototype of a hardware and web-based social and behavioral intervention to improve self-regulation (SR) of students in grades 3 to 5. The prototype will include a wearable wristband that gently vibrates from time to time during the school day to prompt students to indicate their level of SR (e.g. level of focus, attention, self-c ...

Chemical warfare agents (CWAs), such as nerve agents and mustard agents, pose serious threats to our warfighters and civilians. Current formulations of dermal medical countermeasures to CWAs can be absorbed through the skin causing systemic toxicities to the patients. These formulations are limited by the FDA for use only in small area of intact skin, which severely restricts the usefulness of the ...

Vadum will develop Chemical, Heterogeneous sensor fusion Incident awareness Module (CHIME)asoftware module that will ingest data from a large number of asynchronous, heterogeneous and multi-tiered sensors to automate the process of estimating the source attributes of a chemical or biological release. CHIME generates estimates from a continuous stream of raw sensor data with successive estimates al ...

Identifying the correct size of a full facepiece respirator for an individual requires a significant degree of skill. Furthermore, the fit assessment procedure is time consuming due to the series of tasks required to calculate the fit factor, a measure of the quality of fit. The Chemical and Biological Defense (CBD) program needs a quicker, less manually intensive, and more reliable method to sele ...

Military respirator masks provide the Warfighter with life critical protection against chemical, biological, radiological, and nuclear (CBRN)threats. To ensure the safety, comfort, and effectiveness of the American Warfighter, it is essential that every Warfighter be assigned arespirator that is properly sized and fitted. However, current methods for sizing and fitting respirators depend on manual ...

Physical Sciences Inc. (PSI) proposes to develop a dual-mode, nanometer-scale, 3D optical imaging system that combines tomographic digitalholographic microscopy (T-DHM) with infrared (IR) absorption spectroscopy. The proposed sensor will be capable of generating high data rate,sub-wavelength axial/lateral resolution, 3D structural images with simultaneous and complementary functional information o ...

The skin is the first line of defense against chemical warfare agents including nerve agents and toxic industrial chemicals, providing a possible barrier or delay to systemic distribution. Some chemicals also can act directly on the skin including the vesicants sulfur mustard and lewisite. Early and rapid skin decontamination is extremely important following exposure to CWAs and TICs because it de ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

Having achieved or exceeded all goals and objectives of the Phase I research program, BioScale has thus demonstrated feasibility of a multiplexed, immuno-electromechanical pathogen detection method. In Phase II, BioScale proposes to advance this research by assembling a complete assay system that integrates discrete, commercial off the shelf (COTS) sample preparation subcomponents with the propri ...
