This paper develops the mechanical and durable samples of C50 high-performance concrete, studies properties, crack resistance, sulfate attack frost impermeability concrete with different mineral admixtures powder fly ash, obtains best admixture ash to improve performance concrete. The results show that doping effect is when ratio prepared 3:2. With increase in powder–fly admixture, slump expans...

The coupling to light mesons leads to large widths and shifts of the energy of the excited states in the baryon spectrum from the predictions of the constituent quark model with three valence quarks. This coupling may be modelled by admixtures of sea-quark qqq(qq̄) configurations in the resonances. A schematic flavor and spin dependent interaction model, similar to the one which reproduces the l...

In this paper, we present the results of complex experimental studies gas admixtures and vertical structure aerosol in atmosphere over Lake Baikal September 2021, performed onboard research vessel (RV) Akademik V.A. Koptyug. Measurements near-water atmospheric layer were carried out using local control means, i.e., chemiluminescent analyzers. The fields sensed a multifrequency polarization aero...

BACKGROUND Significant precipitation produced by the dilution of diazepam (DZP) injection with an infusion fluid is a great concern for the clinical practice. In this study, the precipitation behavior under different conditions was investigated. METHOD For the sample preparation, DZP injections (Horizon injection and Cercine injection) were diluted with various infusion fluids (Saline, 5% glu...

A self-compacting concrete (SCC) is the one that can be placed in the form and can go through obstructions by its own weight and without the need of vibration. Since its first development in Japan in 1988, SCC has gained wider acceptance in Japan, Europe and USA due to its inherent distinct advantages. Although there are visible signs of its gradual acceptance in the North Africa through its li...
