This work presents an investigation of fundamental combustion properties, specifically laminar burning velocity and ignition delay time, Alcohol-to-Jet Synthetic Paraffinic Kerosene (AtJ-SPK). Used in blends, this fuel is a sustainable aviation that consists mostly two long-chained, highly branched alkanes. Laminar velocities were measured at preheat temperature 473 K pressures 1 3 bar using th...

The present paper contains experimental data obtained in a continuation of the study of the influence of protein on the activity of yeast invertase, when the latter catalyzes the hydrolysis of sucrose in solutions more acid than the pH optimum of the enzyme, 4.5. In an earlier paper’ it was pointed out that native proteins, in the more acid part of the pH range of the enzyme, increase the activ...

In this study, flue gas heat recovery potential was determined by using the measurements from boilers of buildings with solid fuel-fired district and central heating systems in Balikesir, Turkey. Potential terms energy savings were examined. The preheated water combustion air supplied to boiler analyzed. Thus, efficiency system increased, achieved providing fuel savings. order reduce temperatur...

Online compressor washing is a promising method of preventing/ recovering the effects fouling on blades. However, proper strategies need to be implemented for online effective since it conducted when engine in operation. This study presents an experimental investigation wash fluid preheating effectiveness suction wind tunnel cascade. Crude oil was uniformly applied cascade blade surfaces using ...

Homogenous charge compression ignition (HCCI) combustion is spontaneous multi-site combustion of a nominally premixed air/fuel mixture that exhibits high rate of pressure rise and short combustion duration. To avoid excessive pressure rise rate and knocking, HCCI engines are fueled with highly diluted mixture using a combination of excess air and/or EGR. HCCI combustion is attractive due to ...

Structural manipulation of the two dimensional graphene surface has been of significant interest as a means of tuning the properties of the nanosheets for enhanced performance in various applications. In this report, a straightforward and highly scalable method is presented to prepare bulk quantities of "holey graphenes", which are graphene sheets with holes ranging from a few to tens of nm in ...

Since Van Slyke (1) originally described a gasometric method for the determination of hemogIobin by analysis of the oxygen-combining power of blood, it has been the practice to saturate the blood with air at atmospheric pressure in a separate vessel and to transfer a sample of the aerated blood to the gas analyzing apparatus. A method is described here which requires less time, material, and ap...

Background: This study aimed to compare the effects of three different frying methods, namely air (AF), microwave (MF), and deep (DF) in corn oil, on moisture texture, as well content absorption carbohydrates acrylamide French fries. Materials Methods: For DF, fresh potatoes were fully dipped oil temperature was set at 160 °C for intervals 3, 5, 7 minutes. In MF, preheated 180 time 160, 180, 20...
