Concrete consumes millions of tons of cement, which causes global warming as cement factories emit huge amounts of carbon dioxide into the atmosphere.Thus, it is essential to explore alternative materials as a substitute of OPC, which are eco-friendly and at the same time cost-effective.Although there are different options available to use industri
Purpose: To describe an unusual case of bilateral acute retinal necrosis (ARN) that was caused by varicella zoster D3 virus in one eye and Epstein-Barr virus in the fellow eye.Observations: A 67-year-old immunocompromised man presented with ARN in the left eye following a dermatomal vesicular rash, with an aqueous sample positive for varicella zost
The article presents the results of research and analysis of specialization of agricultural organizations of the Chelyabinsk region for the period from 2006 to 2017, which according to the population ecology of organizations has advantages in Floor Lamp stable or specific environments.To study the specialization of the organizations of the agro-ind
Shading greenhouse may be an effective method to achieve a suitable environment for crop growth and to enhance crop yield and quality in places or seasons where there is high light intensity.Therefore, solar radiation levels may modify the biomass accumulation and bromatological composition.Different solar radiation levels (100%, 70% and 50% of ava
This article presents a study of the backward bending mode of a simply supported rotating Rayleigh CLEAN COFFEE DARK ROAST beam with internal damping.The study analyses the natural frequency behaviour of the backward mode according to the internal viscous damping ratio, the slenderness of the beam and its spin speed.To date, the behaviour of the na
