Background Biomass-derived jet fuel is an alternative jet fuel (AJF) showing promise of reducing the dependence on fossil fuel and greenhouse gas emissions. Hydroprocessed esters and fatty acids (HEFA) concept is also known as one of the pathways for producing bio jet fuel. HEFA fuel was approved by the American Society for Testing and Materials in 2011, and can be blended up to 50% with conven...

motor units (mus) reflect the function of the central nervous motor system. thus, the estimated mu number is a good option to investigate the functional movement disorder in the parkinson’s disease (pd). the purpose of this study was to compare the estimated mus number in the medial gastrocnemius (mg) muscle of the normal rats and those with the parkinsonism. the mg muscle of two age-matched gr...

background and purpose: considering the obstacles against the implementation of ethical decisions by nurses, experiencing moral distress is one of the major issues in this profession. moral distress could have negative effects on the physical and mental health of nurses, quality of patient care and performance of health organizations. given the importance of addressing moral distress in working...

as renewable energy increasingly penetrates into power grid systems, new challenges arise for system operators to keep the systems reliable under uncertain circumstances, while ensuring high utilization of renewable energy. this paper presents unit commitment (uc) which takes into account the volatility of wind power generation. the uc problem is solved with the forecasted intermittent wind pow...

Hydroprocessing has become the main technology for the production of API Group II and III base oils. One of the key properties is viscosity index for Group II and III base oils. The effect of wax content in hydrocracker unconverted oil on viscosity index and yield was studied in a 400 kton/year hydroisomerization dewaxing plant at a total pressure of 15 MPa, a feed rate of 38 ton/hour, and a ga...

abstract background: most of the patients admitted in the intensive care units (icus) require an endotracheal tube and mechanical ventilation. in order to clear and maintain patency of the airways, endotracheal suctioning is required. therefore, the least detrimental way of endotracheal tube suctioning which can diminish the complications should be selected. the present study aimed to compare t...

abstract background: while critical care nurses are vulnerable to burnout because of the complex nature of patients’ health problems, working in critical care areas has become even more complicated by shift working schedules. this study aimed to determine the relationship between fixed and rotating shifts and burnout in a sample of critical care nurses working in critical care areas. materials ...

background craniosynostosis results from premature closure of one or more cranial sutures, leading to deformed calvaria and craniofacial skeleton at birth. postoperative complications and outcome in intensive care unit (icu) is related to surgical method and perioperative management. this study determined the perioperative risk factors, which affect outcome of patients after craniosynostosis su...

malaria is a parasitic disease that is starting to be encountered in intensive care units (icu) worldwide, owing to increasing globalisation. severe malaria caused by plasmodium falciparum , is characterised by cerebral malaria, acute renal failure, hypoglycaemia, severe anaemia, splenomegaly and alveolar oedema. we present the case of a 25-yr old male patient who presented to the emergency dep...
