Reinforced concrete elements of the Zagorsk-2 pumped storage station structure had got into unexpected stress-strain state after unequal settlement and bending of the structure crosswise of the flow as a result. Cracks emerged in the load bearing rei

Lack of knowledge about the causes of fatigue often leads to ignoring this symptom in rheumatoid arthritis (RA). The severity of fatiguein patients with RA can be significantly reduced by actively using non-pharmacological treatment strategies.Aim. T

A frequency domain approach to the E-pulse radar target discrimination technique is introduced. This approach allows the interpretation of E-pulse phenomenon via the E-pulse spectrum. The discrete E-pulse and its relation to continuous E-pulse are sh

Radiation emitted by tunable cw CO2 and CO lasers was frequency-converted to the ultraviolet range (300 nm) in potassium vapor by parametric mixing using pump radiation exciting two-photon resonances 8S1/2, 9S1/2, and 7D3/2,5/2 in the potassium atom.
