OBJECTIVE We tested whether the continuous monitoring of dynamic compliance could become a useful bedside tool for detecting the beginning of collapse of a fully recruited lung. DESIGN Prospective laboratory animal investigation. SETTING Clinical physiology research laboratory, University of Uppsala, Sweden. SUBJECTS Eight pigs submitted to repeated lung lavages. INTERVENTIONS Lung recr...

Damage to building load-bearing members (especially columns) under explosions and impact are critical issues for structures, given that they may cause a progressive collapse remarkably increase the number of potential victims. One best ways deal with this issue is provide values safe protective distance (SPD) structural verify, so amount damage (probability exceedance low damage) cannot exceed ...

This study performed a fluid/material coupled numerical simulation of the first stage non-spherical collapse bubble near wall and investigated stress state inside elastic material according to change in stand-off distance γ between wall. The relationship behavior propagation waves was confirmed for typical modes: pancake-shaped mode at = −0.3, hemispherical 0, microjet 0.3 < 1.0, detaching &...

To assess the performance criteria of the reinforced-concrete, five-storey residential buildings common in Iran, an &#10experimental study in the structural laboratory of the University of Tehran has been conducted. The test program includes cyclic and monotonic load tests of six beams that represent three-to-five storey buildings with rigid frame structures. Using definitions given in FEMA-356...

Chloroacetaldehyde (CAA) is a chlorination by-product in finished drinking water and a toxic metabolite of a wide variety of industrial chemicals (e.g. vinyl chloride) and chemotherapeutic agents (e.g. cyclophosphamide and ifosfamide). In this research, the cytotoxic mechanisms of CAA in freshly isolated rat hepatocytes were investigated.CAA cytotoxicity was associated with reactive oxygen spec...

Fifty percent of trauma patients who present sepsis-like syndrome do not have bacterial infections. This condition is known as systemic inflammatory response syndrome (SIRS). A unifying factor of SIRS and sepsis is cardiovascular collapse. Trauma and severe blood loss cause the release of endogenous molecules known as damage-associated molecular patterns. Mitochondrial N-formyl peptides (F-MIT)...
