Hydrodynamic role of fish squamosal integument as an analog of the surfaces directly formed by the turbulent flow. Report 2: Hydrodynamic function of squamosal integument

The stream flowing round the slowly swimming squama free fish can be laminized with the aid of the external slime coat alone. The slime of the fish with well developed squamae can laminize the stream together with the squamatic integument. Adjustments preventing a loss of the slime during laminization are better developed in the fastest squama free fishes

Development of company’s management framework on the basis of value chain

Purpose: To achieve the highest performance, manufacturers tend to transform their management frameworks and develop growth strategies. Utilizing the value chain concept authors analyzed the elements of value chain in the context of fast moving consumer goods'(FMCG) environment. Design/Methodology/Approach: The study involves outputs of two expert surveys generating the Osterwalder's pattern as well as modelling the omnichannel environment and three basic standpoints - FMCG frameworks. Key success factors and their strength were evaluated. Findings: The results of the study form the methodological basis for improving the efficiency of management of trade companies. The findings indicate a certain similarity of the structure of the standard FMCG implementation systems selected by experts from distributor warehouses with the participation of structured retail and the implementation of standard FMCG through unstructured retail. At the same time, the business model used in the implementation of emotional FMCG with minimal participation of structured retail differs from the two similar options mentioned above in almost all parameters, excluding key activities. Practical implications: Recommendations on the structure of management systems (including the specifics of business models) could be used by manufacturers in the formation of value chains involving the three emerging branches of retail trade in consumer goods. Originality/Value: The structure of value chains based of key success factors on three emerging markets, as well as the features of values chains' management systems were first described.peer-reviewe

A stereodivergent asymmetric approach to difluorinated aldonic acids

A (bromodifluoromethyl)alkyne has been deployed in a stereoselective route to difluorinated aldonic acid analogues, in which a Sharpless asymmetric dihydroxylation reaction and diastereoisomer separation set the stage for phenyl group oxidation

Spin torque ferromagnetic resonance with magnetic field modulation

We demonstrate a technique of broadband spin torque ferromagnetic resonance (ST-FMR) with magnetic field modulation for measurements of spin wave properties in magnetic nanostructures. This technique gives great improvement in sensitivity over the conventional ST-FMR measurements, and application of this technique to nanoscale magnetic tunnel junctions (MTJs) reveals a rich spectrum of standing spin wave eigenmodes. Comparison of the ST-FMR measurements with micromagnetic simulations of the spin wave spectrum allows us to explain the character of low-frequency magnetic excitations in nanoscale MTJs.Comment: Also see: http://faculty.sites.uci.edu/krivorotovgroup
