Environmentally friendly sonocatalysis promoted preparation of 1-thiocarbamoyl-3,5-diaryl-4,5-dihydr
Pizzuti, L.; Piovesan, L. A.; Flores, A. F. C.; Quina, F. H.; Pereira, C. M. P.; ; An efficient and green synthesis of thiocarbamoyl-3,5-diaryl-4,5-dihydro-1H-pyrazoles via the condensation of chalcones with thiosemicarbazide in ethanol and KOH under ultrasound irradiation is reported. The products were isolated in good yields after short reaction times.;

Pizzuti, L.; Martins, P. L. G.; Ribeiro, B. A.; Quina, F. H.; Pinto, E.; Flores, A. F. C.; Venzke, D.; Pereira, C. M. P.; ; An ultrasound-assisted preparation of a series of novel 3,5-diaryl-4,5-dihydro-1H-pyrazole-1-carboximidamides that proceeds via the efficient reaction of chalcones with aminoguanidine hydrochloride under clean conditions is described.;
Small-scale photovoltaic-powered reverse osmosis plant without batteries: Design and simulation
Riffel, D. B.; Carvalho, P. C. M.; ; A small-scale photovoltaic (PV) powered reverse osmosis (RO) plant is designed to operate at variable flow/ pressure conditions for stand-alone applications in equatorial areas to desalinate brackish water. Two operation strategies for a PV array of 165 Wp (3 modules of 55 Wp) are simulated and compared: Plant 1 uses two modules for the RO…;
Transient modeling of an adsorber using finned-tube heat exchanger
Riffel, D. B.; Wittstadt, U.; Schmidt, F. P.; Núñez, T.; BELO, F. A.; LEITE, A. P. F.; Ziegler, F.; This paper presents a heat and mass transfer simulation of an adsorber, taking into consideration the geometry of the heat exchanger and the diffusion in the adsorbent medium. The model is validated by experimental data of different adsorbents, volume flows and temperatures. All data were collected in an adsorber test bench at Fraunhofer ISE. As…;
Insights from KPMG?s European Knowledge Management Survey 2002/2003
Gerard Kok, S. J. ; Preface KPMG\'S KNOWLEDGE MANAGEMENT SURVEY 2002/2003 Recently KPMG Knowledge Advisory Services conducted a detailed survey on knowledge management among top 500 organisations in the United Kingdom, France, Germany and the Netherlands. The aim of the survey is to act as a benchmark for the current state of knowledge management in the European profit and non-profit…;
Knowledge Management in Poland 2004
Mariusz Strojny; In the Knowledge Economy, knowledge is the most valuable asset and the only source of sustainable competitive advantage. Increasingly, what organisations know determines the degree of business success. The question we need to face now is how to turn the vision into reality: how to make optimum use of the knowledge that the organisation possesses…;
The Agile Scaling Model (ASM): Adapting Agile Methods for Complex Environments
Scott W. Ambler; The Agile Scaling Model (ASM) defines a roadmap for effective adoption and tailoring of agile strategies to meet the unique challenges faced by a system delivery team. The first step to scaling agile strategies is to adopt a disciplined agile delivery lifecycle which scales mainstream agile construction techniques to address the full delivery process, from…;
Clinical Assessment and Management of Obesity in Individuals With Spinal Cord Injury: A Review
Suparna Rajan, PhD; Marguerite J. McNeely, MD, MPH; Catherine Warms, PhD, RN; Barry Goldstein, MD, PhD; Background: Diagnosing and managing obesity in individuals with spinal cord injury (SCI) remain challenging. Methods: Literature on the epidemiology, impact, and management of obesity in individuals with SCI was reviewed. Findings: Although nearly 66% of individuals with SCI are either overweight or obese, little guidance is available to measure and monitor obesity in the clinical…;
Physical capacity in wheelchair-dependent persons with a SCI: critical review of literature
JA Haisma, L. V. D. W.; JBJ Bussmann; ; Study design: Review of publications. Objective: To assess the level of physical capacity (peak oxygen uptake, peak power output, muscle strength of the upper extremity and respiratory function) in wheelchair-dependent persons with a spinalcord injury (SCI). Setting: Erasmus MC, University MedicalCentre Rotterdam, The Netherlands. Methods: Pubmed (Medline) search of publications from 1980 onwards. Studies were…;
Treadmill training after spinal cord injury: It?s not just about the walking
Audrey L. Hicks, PhD;* Kathleen A. Martin Ginis, PhD; Abstract—Body weight-supported treadmill training (BWSTT) is being used throughout the world as a method for improving functional ambulation after spinal cord injury (SCI). This therapy, however, is very labor-intensive, and recent evidence suggests that it may not be superior to other more conventional forms of rehabilitation for improving locomotor ability. Recognizing that the value of…;
Body Mass Index and Body Composition Measures Dual X-Ray Absorptio in Patients Aged 10 to 21yrs SCI
Craig M. McDonald, MD; Allison L. Abresch-Meyer, BS; Mindy Dopler Nelson, MS; Lana M. Widman, MS; Background/Objective: To determine the body composition of adolescents with spinal cord injury (SCI) and to assess whether established cutoff values for obesity determined by body mass index (BMI) are valid for this population. Methods: Sixty patients, aged 10–21 years, with traumatic SCI (50 with paraplegia and 10 with tetraplegia) were compared with 60 gender-, age-,…;
A Comparison of Hydrostatic Weighing and Air Displacement Plethysmography in Adults With Spinal Cord
Jody L. Clasey, P.; Clasey JL, Gater DR Jr. A comparison of hydrostatic weighing and air displacement plethysmography in adults with spinal cord injury. Arch Phys Med Rehabil 2005; 86:2106-13. Objectives: To compare (1) total body volume (Vb) and density (Db) measurements obtained by hydrostatic weighing (HW) and air displacement plethysmography (ADP) in adults with spinal cord injury (SCI);…;
Physical capacity and race performance of handcycle users
Thomas W.J. Janssen, PhD, FACSM; Annet J. Dallmeijer, PhD; Lucas H.V. van derWoude, PhD; Abstract—The purpose of this study was to determine physical capacity, gross efficiency (GE), and physical strain (PS) of 16 male handcycle users during a 10K race, and to relate these to race performance. All subjects used a handcycle system attached to their own wheelchair and were classified into a group with (A1/A2; N=10) and without…;
