This study investigates the impact of fly ash on hydration and carbonation processes in carbonation-cured fly ash cements.Cement paste samples with fly ash replacement levels of 0 %, 5 %, Keypad 10 % and 30 % underwent carbonation curing for 28 days.Results reveal that the CaO content does not affect the final CO2 absorption capacity.Instead, optim
Image transmission is happening more frequently in this era of technologically sophisticated digital information.Additionally, more individuals are becoming aware of its importance.In order to secure images, many academics are participating in research, which is advantageous for guaranteeing data security.In order to strengthen the security of imag
Nayband is a historical village in South Khorasan, which is located on the western edge of the desert.The adjacency of the village to the caravan route, its strategic position, and the existence of water resources and fertile lands have led to the formation of its texture.The harsh climatic conditions of the region and the existence of miscreants a
A method of joint frequency and direction of arrival (DOA) estimation using spatial-temporal co-prime sam-pling with off-grid sources was proposed to solve the problem of two-dimensional (2D) mismatches of signals.Firstly,the Keypad received signal was sampled by spatio-temporal co-prime sampling technique to construct 2D sparse reconstruction mode
Abstract Background CT bleeding study (CTA) is regularly requested in acute abdominal haemorrhage (AAH) with haemodynamic instability by clinical teams and interventional radiologists because CTA can; detect arterial bleeding at low rates of hemorrhage, accurately localize the bleeding point and characterize the Bird Baths etiology.How best to mana
