Endemic plant species are usually more vulnerable to anthropogenic threats and natural changes and, therefore, hold a higher extinction risk.The preservation of these species is a major concern on a worldwide context and in situ protection alone will not guarantee their conservation.Ex situ conservation measures must be undertaken to support the co
We investigate barely buff gelish the cooling phenomenon of a mechanical oscillator in a double-coupled cavity optomechanical system.Our model includes two single-mode optical cavities.The left cavity is an optomechanical system with an optical parametric amplifier, and the right cavity is a standard optical cavity.The two optical cavities couple w
Aiming at improving the corrosion resistance of AZ31 magnesium alloy in 3.5% (mass fraction) NaCl solution, the effects liftmaster expansion board of CeO2 concentration and ultrasonic and non - ultrasonic assisted processes on chemical conversion film of AZ31 magnesium alloy prepared in the mixed bath of 0.300 mol/L Na2MoO4+0.120 mol/L NaF +
Within latest decades cast-in-place construction of residential houses has been actively developed.Works on erection of cast-in-place frame of the building are normally performed by phases, which results in a necessity to perdieme lingerie arrange construction joints of concreting.In accordance with regulatory documents, it is allowed to arrange co
