We establish sharp estimates of the LqL_q-norms on any finite interval for the polynomials and splines and their derivatives with the help of local LpL_p-norms of these polynomials and splines.

Diuretics increase the urine volume and sodium excretion, and therefore, they are often used to remove the excess fluid from the body during various diseases, including hypertension, heart and kidney failure, nephrotic syndrome, cirrhosis, and a number of... see more

The objectives of this research are to assess the performance of engineering stu-dents when using mathematical competences to solve problems with derivatives, to analyze their difficulties, and to observe which secondary school contents are essential for ... see more

On the model of acute normobaric hypoxic hypoxia with hypercapnia the antihypoxic action of new derivatives of benzilic acid, namely – N-heterylamides of benzilic acid and products of their intramolecular cyclodehydration – thienolactams with five-, six- ... see more

Aim. To study the antihypoxic and antioxidant activity of 5,7-dihydro-1H-pyrrolo-[2,3-d]pyrimidine derivatives on the models of the experimental pathology.Materials and methods. The study of the antihypoxic activity of 5,7-dihydro-1H-pyrrolo-[2,3-d]pyrimi... see more

The results of screening of 2-(benzoyilamino)(1-R-2-oxoindolin-3-ylidene)acetic acid derivatives on the antihypoxic activity are presented in the article. It has been determined that under the conditions of acute hyp?baric hypoxia compounds 4, 14 and 15 h... see more
