This study investigates the bond behavior of corroded reinforcing steel confined with carbon fiber reinforced polymer (CFRP). Corrosion of steel reinforcement in reinforced concrete structural elements could pose a significant problem that may result in loss of structural capacity and even failure. Very few studies have investigated the performance of the bond in corroded confined specimens. The conclusions from these studies suggest that the confinement prevents the reduction of bond strength even after considerable deterioration. Results reported in this paper provide quantitative information regarding the effectiveness of CFRP confinement. Bond tests were conducted on pull-out specimens with 10, 13, 19, and 25 mm [#3, #4, #6, and #8] diameter steel bars corroded to various levels and confined with CFRP. The primary independent variables investigated were: four bar sizes, various levels of corrosion and number of CFRP layers used for confinement. The results indicate that confinement can be effectively used to prevent the degradation of bond strength even at the highest levels of corrosion (12% mass loss) evaluated in this study. The loss of strength for unconfined specimens reached as high as 80%. As expected, confinement was more effective in bars with larger relative rib area. Confinement was also effective in maintaining the ductility. © 2011 Elsevier Ltd All rights reserved. Source

Power-pulsed lavage is a common adjunct to surgical wound debridement, although few studies have examined the effect of this technique in lower extremity wounds. Fifty-five consecutively enrolled patients underwent 73 surgical debridements with power-pulsed lavage, and specimens were obtained for Gram stain and culture and sensitivity analyses before and after lavage. A number of risk factors were analyzed in regard to a successful outcome, which was defined as the absence of any organisms observed on the immediate postlavage culture. The incidence of a successful outcome was 69.86%, and debridement plus power-pulsed lavage statistically significantly decreased bacteria between the immediate prelavage and immediate postlavage specimens, for Gram stain (P = .0004) and culture (P = .005) analyses. Generalized estimation equations provided fully adjusted effect estimates that revealed a decreased likelihood of observing success if the patient's age was 85 years or older, or if rare or many organisms, or gram-negative rods, were present on the immediate prelavage Gram stain; whereas an increased likelihood of success was observed if the patient's body mass index was indicative of normal weight, and if few bacteria were noted on the immediate prelavage culture specimen. Based on these results, we concluded that power-pulsed lavage can be effective in decreasing the presence of bacteria in lower extremity wounds, and an awareness of the patient characteristics and microbiological factors associated with the persistence of bacteria may be helpful to surgeons treating such wounds. © 2010 American College of Foot and Ankle Surgeons.

We describe a novel neuroinformatic platform, the BAMS2 Workspace (http://brancusi1.usc.edu), designed for storing and processing information on gray matter region axonal connections. This de novo constructed module allows registered users to collate their data directly by using a simple and versatile visual interface. It also allows construction and analysis of sets of connections associated with gray matter region nomenclatures from any designated species. The Workspace includes a set of tools allowing the display of data in matrix and networks formats and the uploading of processed information in visual, PDF, CSV, and Excel formats. Finally, the Workspace can be accessed anonymously by third-party systems to create individualized connectivity networks. All features of the BAMS2 Workspace are described in detail and are demonstrated with connectivity reports collated in BAMS and associated with the rat sensory-motor cortex, medial frontal cortex, and amygdalar regions. © 2014 Wiley Periodicals, Inc.

IMPORTANCE Hospitalist physicians face increasing pressure to maximize productivity, which may undermine the efficiency and quality of care. OBJECTIVE To determine the association between hospitalist workload and the efficiency and quality of inpatient care. DESIGN, SETTING, AND PARTICIPANTS We conducted a retrospective cohort study of 20 241 admissions of inpatients cared for by a private hospitalist group at a large academic community hospital system between February 1, 2008, and January 31, 2011. EXPOSURES Daily hospitalist workload as measured by relative value units and patient encounters from the hospitalist billing records. MAIN OUTCOMES AND MEASURES The main outcomeswere length of stay (LOS), cost, rapid response team activation, in-hospital mortality, patient satisfaction, and 30-day readmission rates. Key covariates included hospital occupancy and patient-level characteristics. RESULTS The LOS increased as workload increased, particularly at lower hospital occupancy. For hospital occupancies less than 75%, LOS increased from 5.5 to 7.5 days as workload increased. For occupancies of 75%to 85%, LOS increased exponentially above a daily relative value unit of approximately 25 and a census value of approximately 15. At high occupancy (>85%), LOS was J-shaped, with significant increases at higher ranges of workload. After controlling for LOS, cost increased by 111 for each 1-unit increase in relative value unit and 205 for each 1-unit increase in census across the range of values. Changes in workload were not associated with the remaining outcomes. CONCLUSIONS AND RELEVANCE Increasing hospitalistworkload is associated with clinically meaningful increases in LOS and cost. Although our findings should be validated in different clinical settings, our results suggest the need formethods to mitigate the potential negative effects of increased hospitalist workload on the efficiency and cost of care. © 2014 American Medical Association.

Flexible packaging, particularly multilayer barrier and pouch packaging, has significant advantages and is expanding rapidly. Flexible packaging is ecologically advantageous due to low use of materials and energy, low carbon footprint and GHG emissions, and reduction in food waste. However, it is still under attack by environmental groups because of difficulty of economic mechanical recycling, so that it presently mostly ends up in landfill. The food, packaging and recycling industries are responding strongly to this attack with programs to educate consumers on sustainability advantages and to obviate landfilling by: Development of new barrier materials and package designs. Development of improved collection, marking and sorting methods. Development of economic new recycling and recovery methods including delamination processes and conversion to energy, fuel and downstream chemicals. Implementation of these various potential routes will depend on local and national logistical, economic and political situations, not just technological factors. Source
