EXPERIMENTAL MILLING TESTS OF CUTTING TOOLS AT STAINLESS STEEL
The article is focused on the issue of cutting tools for group of materials M, according to ISO 513, more specifically the area of stainless steel machining. The main objective is to do a practical comparison of selected milling cutters and their inserts at machining of the world's leading manufacturers as Pramet Tools, Mitsubishi, Sandvik and Seco. Experimental testing is focused on functional cutting tests at machining which aim is to test and check significant methods as technique of chip formation during cutting, trajectory of chips leaving, shape and size of chip, tool’s operation in cut (noisiness, vibration) or tool’s operation in cut at various axial depths of cut. Selected tests will be performed on the milling centre Kovosvit MAS MCV 1270 Power, and stainless steel X2CrNiMo1712-2 will be selected as machined material.

Rational Design, Synthesis and Evaluation of γ-CD-Containing Cross-Linked Polyvinyl Alcohol Hydrogel as a Prednisone Delivery Platform
This study describes the in-silico rational design, synthesis and evaluation of cross-linked polyvinyl alcohol hydrogels containing γ-cyclodextrin (γ-CDHSAs) as platforms for the sustained release of prednisone (PDN). Through in-silico studies using semi-empirical quantum mechanical calculations, the effectiveness of 20 dicarboxylic acids to generate a specific cross-linked hydrogel capable of supporting different amounts of γ-cyclodextrin (γ-CD) was evaluated. According to the interaction energies calculated with the in-silico studies, the hydrogel made from PVA cross-linked with succinic acids (SA) was shown to be the best candidate for containing γ-CD. Later, molecular dynamics simulation studies were performed in order to evaluate the intermolecular interactions between PDN and three cross-linked hydrogel formulations with different proportions of γ-CD (2.44%, 4.76% and 9.1%). These three cross-linked hydrogels were synthesized and characterized. The loading and the subsequent release of PDN from the hydrogels were investigated. The in-silico and experimental results showed that the interaction between PDN and γ-CDHSA was mainly produced with the γ-CDs linked to the hydrogels. Thus, the unique structures and properties of γ-CDHSA demonstrated an interesting multiphasic profile that could be utilized as a promising drug carrier for controlled, sustained and localized release of PDN.
