In this paper, we mainly seek conditions on which the geometric properties of subclasses of biholomorphic mappings remain unchanged under the perturbed Roper-Suffridge extension operators. Firstly we generalize the Roper-Suffridge operator on Bergman-Hartogs domains. Secondly, applying the analytical characteristics and growth results of subclasses of biholomorphic mappings, we conclude that the generalized Roper-Suffridge operators preserve the geometric properties of strong and almost spiral-like mappings of typeβand orderα,SΩ⁎(β,A,B)as well as almost spiral-like mappings of typeβand orderαunder different conditions on Bergman-Hartogs domains. Sequentially we obtain the conclusions on the unit ballBnand for some special cases. The conclusions include and promote some known results and provide new approaches to construct biholomorphic mappings which have special geometric characteristics in several complex variables.

For many years, an increasing number of diagnosed atopy and skin problems have been observed. For people affected by the problem of atopy, the selection of skin care products, including cosmetics, is extremely important. Cleansing cosmetics, due to their ability to cause skin irritations and disturb the hydrolipidic barrier, can increase problems with atopic skin. New solutions to reduce the effects of these products on the skin are very important. In this work, the effect of ectoine on the properties of anionic surfactants was analyzed. Based on model systems, analysis of the effect of ectoine on the irritating effect of four anionic surfactants and their ability to solubilize model sebum was performed. Antioxidant activity was also evaluated, and cytotoxic studies were performed on cell cultures. It was shown that the addition of ectoine to the anionic surfactant solutions improves its safety of use. After introducing ectoine to the surfactant solution, a decrease of irritant potential (about 20%) and a decrease in the ability to solubilize of model sebum (about 10–20%) was noted. Addition of ectoine to surfactant solutions also reduced their cytotoxicity by up to 60%. The obtained results indicate that ectoine may be a modern ingredient that improves the safety of cleansing cosmetics.

Methodological Comparison

AbstractThis contribution aims at an original comparison of development analysis with Elinor Ostrom and Esther Duflo from a methodological standpoint, scrutinising their relationship to theory and their operative research strategies. Both perspectives are investigated as case studies for a broader discussion about significant trends in economics and social sciences. Duflo and the J-PAL's approach illustrates – in its own way – new trends and some blind alleys in contemporary forms of mainstream economics, whereas Ostrom and the Bloomington school point towards the marked theoretical and methodological reflexivity of institutionalism, its sensitivity to historical diversity and openness towards social sciences. Distinct social philosophies and episteme are at stake displaying a great divide between two brands of realism and pragmatism, two relationships to development, expertise and knowledge. The paper also contrasts Duflo's methodological monism and mechanistic piecemeal analysis with Ostrom's methodological pluralism and adaptive complex systems analysis.
