Heat removalMelting unitSurfaceCalculationLead–bismuthTemperatureThe article presents a conceptual analysis of the feasibility of lead–bismuth coolant application for cooling the melting unit steel vessel designed for implementation of a new efficient radwaste reprocessing technique. In support of the lead...
melting ice or sublimations of frozen carbon dioxide. By melting ice, heat is transferred by convection from the warmer air inside a refrigerated space to the ice which absorbs 333.55 kJ/kg of heat, making the refrigerated space cooler than ambient. Moreover frozen ice carbon dioxide sublimes ...
Melting ice can also cause sea level to rise in the long term. Since 1993, sea level has risen at a rate of 3. 2 cm every 10 years, The Guardian reported. Some countries, such as Tuvalu (图瓦卢)in the South Pacific Ocean and Maldives(马尔代夫) in the Indian Ocean, ar...

A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate. In 2013, a lot of people were shocked by a news photo of a dead polar bear that was found on Norway’s Arctic island of Svalbard. According to the ...
1. The plum trees(梅树) are the first to flower even as the snow is melting (融化). They represent the promise of spring and a renewal of life. (2020 全国) ___2. Most employers do care about the personal appearances of their employees, because those people represent the companies to ...
In Ti–6Al–4V alloy-based structures manufactured using L-PBF, the residual stresses can reach up to a value of 250 MPa. Which can be relieved by heat treatment process around temperature of 800 °C [93]. Yang et al. (2021) observed high residual stress and dislocation density causing ...
The solution-diffusion mechanism (Favvas et al., 2017) is based on the solubility of specific gases and their diffusion in the membrane matrix. In this mechanism, each of the gases is absorbed and dissolved on the upstream surface of the membrane and moves across the membrane by diffusion. ...
