Double-edged blinde, hemorrhagic or cardioembolic cognitive impairment

Journal of Geriatric Cardiology 2016年第8期13卷 724-726页

作者： Levent Cerit hatice kemal Aziz Gunsel Hamza Duygu Department of Cardiology Near East University Nicosia Cyprus

To the Editor I have read the article entitled ＂Cognitive function and adherence to antieoagulation treatment in patients with atrial fibrillation＂ by Jankowska-Polafiska, et al., with great interest. The investigators reported that cognitive impairment is an independent determinant of compliance with pharmacological therapy in elderly patients with atrial fibrillation （AF）.

In this study, an experimental study was carried out to determine the effects of adding different amounts of graphene oxide (GO) on engine characteristics to a single-cylinder diesel engine operating with 30% sesame oil (SO) + 70% diesel fuel mixture. After that, an optimization was carried out with response surface methodology (RSM) to determine optimum operating conditions at different engine loads. Experimental results showed that GO nanoparticle is a good addition for diesel–biodiesel blends to enhance the performance and reduce emissions. The most appropriate amount of GO is between 75 ppm and 100 ppm for the performance characteristics. The optimal amount of GO for power is 75 ppm, while for brake-specific fuel consumption (BSFC) and exhaust gas temperature (EGT) it is 100 ppm. In addition, the maximum GO amount of 100 ppm is the most suitable for carbon monoxide (CO) and hydrocarbon (HC), and 75 ppm GO amount is the most appropriate for nitrogen oxides (NOx). On the other hand, optimization results revealed that 100 ppm GO at 1950 W load was optimum conditions for all responses. The responses that emerged under optimum conditions were 1746.77 W, 968.73 g/ kWh, 259.8 ⁰C, 0.0603%, 23.13 ppm and 185.61 ppm for power, BSFC, EGT, CO, HC, and NOx, respectively. According to the validation study, the error between the optimum and experimental results is 4.69% maximum. According to the findings of study, it can be concluded that the RSM model can successfully model a singlecylinder diesel engine and thus save time, and money.
