Question One

The portable fire extinguishers play a significant role in putting out the fires that break out within the buildings. In essence, these devices act as a first aid response to the fires and help prevent the destruction of properties as well as loss of lives. The thorough inspection, testing, and servicing of these firefighting devices in buildings is highly recommended under the Australian regulations. The inspection checklists help ensure that the portable fire extinguishers are ready for use if they are ever needed. The following assessment checklist is for the on-site inspection of the portable aerosol fire extinguisher located ...

Increased erythropoietin production Increased heart rate Increased cardiac output Enhancement in oxygen extraction The answer for this question is b. increased heart rate. A reduction in tissue oxygenation as happens in anemia stimulates increased production of erythropoietin through a complex feedback mechanism. Increased production of erythropoietin enhances erythropoiesis in anemia. Increased extraction of oxygen in anemia is a compensatory mechanism that is mediated by an increase in 2, 3-diphosphoglycerate concentrations. Increased cardiac output is the main hemodynamic compensatory mechanism in anemia that aims to increase blood flow to the body organs. An increase in heart rate ...

The single-celled parasite, Plasmodium falciparum, causes malaria, was responsible for 214 million cases and 438,000 deaths globally in 2015, of which 88% of cases and 90% of deaths occurred in sub-Saharan Africa. The morphology of P. falciparum is characterized by numerous rings (young trophozoites) and the absence of mature trophozoites and schizonts. In a P. falciparum blood smear, multiple infected erythrocytes appear more often than in other species and the rings of the parasite in the blood smear tend to be smaller than other species. Distinctive crescent-shaped gametocytes appear late in the infection. In vitro cultivation of P. ...

Abstract

Among the remarkable flight accidents, Saudia Flight 163 case holds a special place, both due to the death toll and due to the fact that it did not involve a crash at all. The disaster that took away lives of all passengers and crew members at the turn of 1980s was thoroughly investigated and recognized as the second deadliest aircraft accident (at that time) after Ermenonville air disaster involving Turkish Airlines flight 891 (Witkin, 1981). While the deadly incident happened after the safe emergency landing of the plane, the main reason of Flight 163 tragedy is human factor. The ...

Introduction

Fire is described as the visible result of an oxidation process in the chemical reaction known as combustion. Combustion occurs between an oxidant (source of fuel) and oxygen which results in the release of heat and the source of fuel being converted into another form (Grimwood et al., 2010). When heat is released, light is produced either as a flame or glowing. The fuels which bring about combustion are mainly organic compounds like hydrocarbons which may be in the solid, liquid, or gaseous phase. The part of the fire which is visible is known as the flame. It is ...
