Abstract Concerns over global warming and the need to reduce carbon emissions have prompted development of novel energy recovery systems. During urban driving, a significant amount is lost due continuous braking, which can be recovered stored. The flywheel storage system efficiently recover store vehicle's kinetic during deceleration. In this study, Computational Fluid Dynamics (CFD) model was ...

Human physiology changes are often amplified in disease states and may be altered when a patient is mechanically ventilated. Normally, systolic blood pressure is slightly lower during inspiration than expiration due to the change in intrathoracic pressure. Pulsus paradoxus is a phenomenon in which the difference in systolic blood pressure (BP) between inspiration and expiration is more than 10 ...

AIM To examine the effect of intermittent positive pressure ventilation (IPPV) on plasma arginine vasopressin concentration (pAVP) in preterm neonates. METHODS Thirty five neonates were classified, at the time of blood sampling, into three groups: unstable ventilated; stable ventilated; and stable non-ventilated. A modification of an extraction method for pAVP was developed for use in studies...

Inhaled bronchodilators are routinely administered to mechanically ventilated patients to relieve dyspnea and reverse bronchoconstriction. A lower percentage of the nominal dose reaches the lower respiratory tract in a mechanically ventilated patient than in a nonintubated subject, but attention to device selection, administration technique, dosing, and patient-ventilator interface can increase...

The care of the mechanically ventilated patient is at the core of a nurse's clinical practice in the Intensive Care Unit (ICU). Published work relating to the numerous nursing issues of the care of the mechanically ventilated patient in the ICU is growing significantly. Literature focuses on patient assessment and management strategies for patient stressors, pain and sedation. Yet this literatu...

schwannoma is a benign encapsulated slow-growing tumor that originates from schwann cells of the peripheral nerve sheath. it usually occurs in the head and neck; however, it is rare in the oral cavity. the tongue is the most common site of intraoral schwannomas, followed by the floor of the mouth, palate, gingiva, vestibular mucosa, lips and mental nerve area. we report a rare case of schwannom...

Well-designed ventilated air-spaces behind external claddings in the building envelope can potentially reduce thermal energy flow entire wall structure. In this study, impact of dynamic thermo-hydraulic behavior naturally cavity on performance lightweight and heavyweight assemblies with traditional passive active (i.e., BIPV) facades is investigated. A numerical transient 2-D model validated ag...

The New Zealand Building Code contains minimum durability requirements for components. For roof structures the requirement is 50 years if component structural or 15 it not. Metal claddings are very common in Zealand, and spaces typically not deliberately ventilated. Recently, a number of roofs failing to meet their requirement, lack deliberate ventilation contributory factor some cases. In this...

spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. spindle cell neoplasms can affect the oral cavity. in the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. this article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology.  ...
