Multicriteria Optimization in Water Resources Distribution Problem

A multicriteria problem on the distribution of water resources between four reservoirs with respect to electricity production in three countries is considered. The reservoirs are connected in a unique water system. The water inflow to one of the reservoirs is considered as the result of water releases from the others at previous time. The problem is to choose water releases which would provide maximum of the electricity in each country and minimum of fluctuations of the water levels in reservoirs as well. The multicriteria non-linear programming system DISO/PC-MCNLP is used for the solution of the problem

First results of the renewed Uragan-2M torsatron

The results of experimental investigation on the vacuum magnetic surfaces in the l=2 torsatron with an additional toroidal field Uragan-2M at wide varying operation parameters are presented. Also the first results on the wall conditioning in the Uragan-2M with the ECR and RF discharges in atmosphere of hydrogen in steady-state mode at low magnetic field, plasma production and heating with RF power are described.Представлено результати експериментального дослідження вакуумних магнітних поверхонь в l=2 торсатроні з додатковим магнітним полем Ураган-2М для широкої зміни операційних параметрів.

Synthesis of C-29-phosphonium derivatives of 3,28-diacetoxylup-20(29)-en-30-oic acid

© 2020, Springer Science+Business Media LLC. 3β,28-Diacetoxylup-20(29)-en-30-oic acid (obtained via oxidation of betulin diacetate) enters the addition reaction with P—H-phosphonium salts (triarylphosphonium trifluoroacetates) under mild conditions to afford β-carboxyalkylphosphonium salts. Structure and composition of the resulting compounds were confirmed by NMR and IR spectroscopy, mass spectrometry, and elemental analysis

3,28-Diacetoxylup-20(29)-ene-30-oic Acid and Its ω-Bromoalkyl Esters

© 2020, Pleiades Publishing, Ltd. Abstract: A convenient procedure has been developed for the synthesis of3β,28-diacetoxylup-20(29)-en-30-oic acid via oxidation of 3β,28-di-O-acetylbetulin with selenium dioxide in aqueousethanol on heating, followed by oxidation of 3β,28-diacetoxylup-20(29)-en-30-althus formed with sodium chlorite in tert-butyl alcohol. The alkylation of3β,28-diacetoxylup-20(29)-en-30-oic acid with 1,3-dibrompropane and1,5-dibromopentane in boiling acetonitrile in the presence of potassiumcarbonate afforded the corresponding ω-bromoalkyl esters in high yields
