Description: With the growing complexity of engineered systems, reliability has increased in importance throughout the twentieth century. Initially developed to meet practical needs, reliability theory has become an applied mathematical discipline that permits a priori evaluations of various reliability indices at the design stages. These evaluations help(More)
1-Vinylpyrrole-2-carbaldehydes react with acetylene at atmospheric pressure in a NaOH/EtOH/DMSO system at 7-10 °C to afford 2-(1-hydroxypropyn-2-yl)-1-vinylpyrroles in 53-94% yield. Thus, the first base-mediated direct ethynylation of pyrrolecarbaldehydes with free acetylene under modified conditions of the Favorsky reaction has been implemented to pave an(More)
Being asked to write a paper about Boris Vladimirovich Gnedenko, we decided to present the material in two parts: Ekaterina Gnedenko writes biographical notes from the angle of his research achievements and Igor Ushakov writes rather personal reminiscence. Gnedenko himself told about his life in the book of his memoirs [1].
