BACKGROUND The aim of this study was to measure chest compression decay during simulated advanced life support (ALS) in a cardiac arrest manikin model. METHODS 19 paramedic teams, each consisting of three paramedics, performed ALS for 12 minutes with the same paramedic providing all chest compressions. The patient was a resuscitation manikin found in ventricular fibrillation (VF). The first s...

Intermittent drying is a satisfactory technique for drying of heat sensitive grains especially rough rice. This method consists of two separate stages applied intermittently: drying and tempering. In this work, intermittent drying of rough rice is investigated both theoretically and experimentally. In order to characterize this process; a multi-scale model consisting of macroscopic and microsco...

The mining industry raises many environmental problems in the ecosystem, one of which is emergence acid mine drainage. Because this issue, study was conducted to see performance dolomite adsorbents purifying drainage at iron ore Aceh Besar, Indonesia. adsorption Cu2+ metal ions using has best equilibrium result a contact time 15 minutes, efficiency reaches 92.97%, and absorption capacity 9.07 m...

sawdust of the most inexpensive and abundant most engrossing read and the ability to absorb heavy metals from water and wastewater types. on the other hand increased metal hexavalent chromium (cr6 +) in drinking water cause toxicity, and complications from it can be. so the purpose of this research, effects of the dosage absorbent sawduste, equilibrium time, the efficiency of absorption and cal...

the present study aimed to determine the effects of 12 weeks of aerobic exercise in different times of day on some cardiovascular risk factors in overweight men. 40 non-athletes, overweight men with an average age of 22.25±2.45 years old and bmi of 30.06±2.42 kg/m2 were randomly allocated to four groups of morning and evening aerobic training and control. morning and evening training groups per...

In this study, the adsorption of amoxicillin onto activated carbon was investigated. The effect of particle size and the effluent flow rate was discussed as well as the kinetics and isotherm of adsorption equilibrium. The isotherm equilibrium studies showed that the Langmuir model was appropriate for describing the adsorption equilibrium of amoxicillin onto the activated carbon. Furthermore, th...

Introduction: Graphene oxide (GO) sheets are carbon-networking nanomaterials offering excellent potential for drug delivery platforms due to hydrophobic interactions and high drug-loading efficiency. Superparamagnetic iron oxide nanoparticles can be used in certain applications such as cell labeling, drug delivery, targeting, magnetic resonance imaging and hyperthermia. Due t...

Background: Cadmium (Cd) is a heavy metal that is widely utilized in industries and contaminates soil and groundwater. There are several environmental problems related to cadmium, therefore, the technical and economic methods of removing Cd are of great importance. So this study was conducted to evaluate the efficiency of a type of plant to remove the Cd from aqueous environments. Methods: In t...
