That is quite enough reasons to use as starting material for a new series of compounds with other biomolecules such as monosaccharides after simple modification. The target molecules show biological activity. So, the current work is aiming to improve the activity and the properties of the benzo indole by attaching with a naturally occurring, and biodegradable compounds represented by 2-deoxy-2-amino -d-glucose and 6-deoxy-6-amino-d-glucose to synthesis both mono and di-saccharides derivatives of benzo indole. Two steps synthesis were used for mono-saccharide derivatives and three steps for di-saccharide derivatives, the first is the functionalization of 1,1,2-trimethyl-1H-benzo[e]indole [1] via the reaction with POCl3 to produce 2-(1,1-dimethyl-1H-benzo[e]indol-2(3H)-ylidene) malonaldehyde [2] with two aldehydes reaction centers, while in the second step the latter was coupled with sugar via amino groups to get the two monosaccharide derivatives [3,5], while the disaccharides molecules [4,6] taken one more step with harder conditions to overcome the steric hindrance at the other reaction center. The purity and characterization of the target molecules was confirmed using spectroscopy methods including 1H NMR and 13 NMR. The synthesized compound shows a good biological activity as antibacterial antifungal. 2023-01-01T00:00:00Z http://148.72.244.84/xmlui/handle/xmlui/16345 Title: Preface: International Conference on Innovations in Science, Hybrid Materials and Vibration Analysis IC-ISHVA 2022 Authors: رعد عبد الكريم حمدان Abstract: The Stirling engine is a kind of reciprocating internal combustion engine. It converts heat into mechanical work and the motor has low vibration, emissions, and noise. The Stirling engine works with any external heat source such as biomass, solar energy, and industrial waste. It was studied some parameters affecting the performance of the engine. Among these parameters studied in this work is the study of the effect of hot source temperature, charge pressure, and engine speed to know the effect of these parameters on the engine’s performance, and which one has the most effect on the operation of the engine. The effect of variables on the performance of the STE-1008 Gamma Stirling engine was studied. The engine contains three types of heat exchangers: heater, cooler, and regenerator. The heater is made of 20 stainless steel tubes with an 8-millimeter internal circumference apiece. The cooler is a finned aluminum heat exchanger with 144 internal fins, each with a cross-sectional area of 1 mm by 10 mm. The regenerator is fitted with a diameter of 31 µm and a volumetric porosity of 90%. The parameters considered are the temp. of the hot source, charging pressure, and engine speed. Nitrogen was used as a working fluid. Results showed that Nitrogen at 800 °C with 2 bar charge pressure gives 630 W while air gives 570 W. 2023-01-01T00:00:00Z http://148.72.244.84/xmlui/handle/xmlui/16305 Title: Preface: International Conference on Innovations in Science, Hybrid Materials and Vibration Analysis IC-ISHVA 2022 Authors: رعد عبد الكريم حمدان, Al-Tamimi, R.
