In this work, it is presented a dynamic model in order to simulate of the biological composting process, applied to the organic fraction of the municipal solid waste. The model was applied to small scale composting units (in-vessel type), processing household wastes composed of food wastes, yard wastes and paper wastes. The model is based in a continuous plug flow reactor for the solids and in ...

The biological stabilisation of the organic fraction of municipal solid waste (OFMSW) into a form stable enough for land application can be achieved via aerobic or anaerobic treatments. To investigate the rates of degradation (e.g. via electron equivalents removed, or via carbon emitted) of aerobic and anaerobic treatment, OFMSW samples were exposed to computer controlled laboratory-scale aerob...

OBJECTIVES The study evaluated the safety and efficacy of stent reconstruction of stenotic/occluded iliofemoral veins (IFV) and inferior vena cava (IVC). BACKGROUND Patients with congenital heart defects and stenotic or occluded IFV/IVC may encounter femoral venous access problems during future cardiac surgeries or catheterizations. METHODS Twenty-four patients (median age 4.9 years) underw...

RATIONALE Perfusion decellularization of cadaveric hearts removes cells and generates a cell-free extracellular matrix scaffold containing acellular vascular conduits, which are theoretically sufficient to perfuse and support tissue-engineered heart constructs. However, after transplantation, these acellular vascular conduits clot, even with anti-coagulation. Here, our objective was to create a...

Background: Neonatal intensive care unit (NICU)Conventionally, Central Venous Pressure (CVP) monitoring has beenused by intensivists to measure intravascular volume. However, it is an invasive procedure resulting in many complications. Non-invasive ultrasonographic measurement of inferior vena cava collapsibility index (IVC-CI) is a promising alternative. Therefore, this study wasconducte...

Abstract Penetrating traumatic injuries can present a challenging scenario due to the potential for multisystem involvement requiring swift collaboration between surgical specialities. We case of 66-year-old female who was stabbed in right posterior chest. CT revealed diaphragmatic injury, liver laceration involving segments 6/7 with active bleeding, and superior mesenteric artery (SMA) anterio...

Composting has traditionally been used as a form of slow rotting of farm-yard manures and vegetative wastes with the resultant humus product useful in agriculture (Balfour; Howard; Wistinghausen & Sattler). However, renewed interest and modern engineering involvement has resulted in an essentially new composting image emphasizing significant technological inputs (Hoitink & Keener, Biocycle; Ryn...
