Physical therapists practicing in inpatient acute care settings in the United States work in a 21st century health care system that requires professional competence in clinical reasoning and decision making. For doctor of physical therapy (DPT) students, the development of confidence in the patient evaluation and the professional skills necessary for managing the inpatient environment can be challenging.The studys purpose was to understand whether the early exposure of students to inpatient settings informed their understanding of the thought processes and actions of experienced clinicians during client interactions.A qualitative design was used.Thirty-three DPT students working in inpatient settings were recruited from 15 unique inpatient hospital (acute care and rehabilitation) facilities with a convenience sampling technique. Reflective data were collected for 1 month with clinician-facilitated discussion boards.Four themes emerged: environment, communication, evaluation, and client-therapist interaction. The themes informed a conceptual model depicting the observation by DPT students of factors that influenced interactions between clients and experienced clinicians in inpatient settings. Reflection on the what, the how, and the why that informed clinical decisions enabled students to recognize the situated nature of evaluation and treatment approaches.The use of a sample from 1 year of a DPT program at one university reduced the generalizability of the results.Limited research has examined student perceptions of the interactions of experienced clinicians with clients in inpatient acute care settings. More research is needed to understand the impact of exposing students to the thoughts and actions of therapists working in such settings earlier within DPT curricula.

Quantum well infrared photodetectors (QWIPs) are well known for their stability, high pixel-pixel uniformity and high pixel operability which are quintessential parameters for large area imaging arrays. In this paper we report the first demonstration of the megapixel-simultaneously-readable and pixel-co-registered dual-band QWIP focal plane array (FPA). The dual-band QWIP device was developed by stacking two multi-quantum-well stacks tuned to absorb two different infrared wavelengths. The full width at half maximum (FWHM) of the midwave infrared (MWIR) band extends from 4.4-5.1 μm and FWHM of the long-wave infrared (LWIR) band extends from 7.8-8.8 μm. Dual-band QWIP detector arrays were hybridized with direct injection 30 μm pixel pitch megapixel dual-band simultaneously readable CMOS read out integrated circuits using the indium bump hybridization technique. The initial dual-band megapixel QWIP FPAs were cooled to 68 K operating temperature. The preliminary data taken from the first megapixel QWIP FPA has shown system NEΔT of 27 and 40 mK for MWIR and LWIR bands, respectively. © 2010 IEEE.

South African environmental, water and consulting company GCS's Max Karen and Andrew Johnstone examine a number of factors that are key to developing sustainable water boreholes. The drilling industry has expanded greatly in Africa, over the past 20 years, especially in the water-supply sector. The objective of providing people, especially poor rural and urban dwellers, with water is of course a noble and vital objective. The key factors that are damaging the long-term functionality and sustainability of water-supply boreholes in Africa are all issues that are known and in many cases have easy solutions.

The successful results of a Global Food Security Project supported by the National Geospatial-Intelligence Agency (NGA), the National Aeronautics and Space Administration (NASA), the United States Department of Agriculture (USDA) and other government entities led to the development of a pilot project where these data experts are coordinating and sharing their expertise with the private sector-to perform project work which requires extremely difficult computational analytics with high volume satellite imagery such as, NOAA-TRMM, NASA-MODIS, NCEP, Air Force-AFWA, AWIFS, SPOT-Veg provided by the USDA and PET datasets which consist of raster and vector data (100's of gigabytes per country). The data have been placed in a secure, interoperable cloud at the Rocky Mountain Supercomputing Centers, Inc. running Microsoft HPC Server 2008 and SQL Server Enterprise with the latest edition of ESRI ArcGIS. The scalable solution is being used to complete high-fidelity analytics: Time series analysis, change detection, correlation analysis for geoprocessing and geostatistics. The outcomes of the project can change earth observation monitoring forever by allowing this same processing for the entire globe, using all the data sets in an interoperable, real-time environment, whether we are looking at Global Food Security issues, Water Resource Management, Provincial Reconstruction or any other application requiring real-time management of multiple input variables these predictive models will save precious resources - time and money - and most importantly provide enormous societal benefit.

The purpose of this study was to determine the effects of prolonged standing on gait characteristics in children with spastic cerebral palsy. Six children with spastic cerebral palsy participated in this study with an average age of 6.5 years (SD 2.5, range 4.09.8 years). A reverse baseline design (A-B-A) was used over a 9-week period. During phase A, the children received their usual physical therapy treatment. During phase B, children received the prolonged standing program three times per week, in addition to their usual physical therapy treatment. During phase A2, children received their usual physical therapy treatment. Gait analysis and clinical assessment of spasticity were performed before and after each phase. Analysis of variance (ANOVA) for repeated measurements was used to test for changes in gait measures across the four measurement sessions. Friedman's was used to test for changes in muscle tone (Modified Ashworth Scale) across the four measurement sessions. Stride length (p <.001), gait speed (p <.001), stride time (p <.001), stance phase time (p <.001), double support time (p <.003), muscle tone (p <.02), and peak dorsiflexion angle during midstance (p <.004) improved significantly following the intervention phase. The results of this study demonstrate that the gait pattern of children with cerebral palsy classified as level II or III on the Gross Motor Functional Classification System (GMFCS) improved by a prolonged standing program. However, these improvements were not maintained at 3 weeks. Further research is necessary with larger sample sizes to replicate these findings and determine specific "dosing" for standing programs to create long-lasting functional effects on gait.

This Small Business Innovation Research Phase I project will create a microcarrier with immobilized growth factors for adherent cultured cells. This advancement in cell culture biomaterials promises to remove the variability associated with growth factors in liquid media while increasing cell culture workflow efficiency. The project is to identify an efficient reaction mechanism for coupling protein, including animal serum and purified fibroblast growth factor (FGF), to the surface of a previously developed magnetic alginate microcarrier. The resulting product is anticipated to have significant benefits over traditional flask culture methods and will provide enabling technology to next generation drug discovery and therapeutics as primary and stem cells become the cell types of choice. The broader impact/commercial potential of this project is the use of immobilized growth factors to advance the basic understanding of cell-substrate interactions. Currently, the major cost for culturing primary and stem cells is the cell growth media, which contains costly purified growth factors. Reducing the amount of growth factors necessary for culture will directly reduce the cost per cell. Furthermore, this product will prove valuable for therapeutic applications including cell-based therapies in which cGMP growth factors would be especially costly. Finally, a growth factor-conjugated microsphere will be a useful basic research platform for understanding the role of "immobilized" growth factors in vivo, which is important for creating bio-scaffolds and regenerative implants.
