As a result of urbanization and economic prosperity, which has accelerated the generation of municipal solid waste (MSW) along with its organic fraction, the management of MSW is a challenge faced by urban centres worldwide, including the European Union (EU) and Canada. Within a concept of waste recovery, the source separation and on-site treatment of urban organic waste (UOW) can resolve some ...

Intravascular catheters (IVCs) are the most frequently used medical devices in hospitals. However, they are associated with life-threatening IVC-related bloodstream infection (IVC-BSI), which is one of the main hospital-acquired infections, and continue to be associated with morbidity, mortality and additional medical cost. Most published studies focus on measuring the rate of IVC-BSIs and addr...

OBJECTIVES Bedside ultrasonography (US) measurement of the inferior vena cava (IVC) and aorta (Ao) may be useful in objectively assessing children with dehydration. The objectives of this study were 1) to compare the IVC and Ao diameters (IVC/Ao) ratio of dehydrated children with controls and 2) to compare the IVC/Ao ratio before and after intravenous (i.v.) rehydration in children with dehydra...

OBJECTIVES Inferior vena cava ultrasound (IVC-US) assessment has been proposed as a noninvasive method of assessing volume status. Current literature is divided on its ability to do so. The primary objective was to compare IVC-US changes in healthy fasting subjects randomized to either 10 or 30 mL/kg of intravenous (IV) fluid administration versus a control group that received only 2 mL/kg. M...

Security is the main concern in wireless communications. Future vehicles may use wireless Inter-Vehicle Communication (IVC) networks to exchange data among each other. IVC networks provide drivers with updated information on traffic and road conditions for efficient and safe driving. The main challenges in designing secure IVC networks are vehicle authentication and data integrity. Vehicle auth...

Thrombosis of Inferior Vena Cava (IVC) following filter insertion can occur in up to 30% of the cases. The optimal management of such cases is unknown. We describe a simple and less expensive method of achieving successful recanalization of the IVC in a 40 year old hypertensive man who developed recurrent pulmonary embolism after his orthopedic treatment. An IVC filter was inserted, which devel...

BACKGROUND The need for patient transport for inferior vena cava (IVC) filter placement impacts patient safety, comfort, charges, and nursing care. Bedside, ultrasound-guided IVC filter placement may offer an acceptable, cost-effective alternative. METHODS Prospective cohort study of 55 consecutive trauma patients requiring IVC filter placement. During a 13-month period (August of 1995-Septem...

Our earlier experiments in small composters (220 l) indicated the favourable effect of ash from co-incineration of sorted dry waste on the composting of catering waste. The aim of this new study was to clarify further, at a scale of 10 m3, the feasibility of using similar ash as an additive in composting. Source-separated catering waste was mixed with bulking agent (peat and wood chips) and fue...
