AbstractCharacteristics of aqueous cement suspensions and the packing nature during setting were investigated as keys controlling the microstructure and density of a cement paste. The theological properties of the paste were studied as functions of hydration and setting; these properties are influenced by a variety of external factors, which are discussed. The objective of this paper is to sketch a new atomistic approach to a group of rheological phenomena which are as interesting from a scientific viewpoint as they are important for technology. The experiments were carried out by a HAAKE rheometer and an acoustic ultrasonic system. At different flow state, the acoustic emission signal generated from micro-structure is transformed due to wave propagation and due to the transducer response. The scientific information obtained through this study is expected to contribute the establishment of concept of setting processing. The measurements of flow properties relating to flocculation and coagulation were evaluated with respect to the effects of processing conditions on structure development in cement paste.

Abstract. This study examines the effect of interactivity on the attribution of responsibility for the character’s actions in a violent video game. Through an experiment, we tested the hypothesis that identification with the main character in Grand Theft Auto IV mediates the effect of interactivity on attributions of responsibility for the main character’s antisocial behavior. Using the framework of the fundamental attribution error, we demonstrated that those who actually played the game, as opposed to those who simply watched someone else playing it, identified with the main character. In accordance with the theoretical expectation, those who played the game and came to identify with the main character attributed the responsibility for his actions to external factors such as “living in a violent society.” By contrast, those who did not interact with the game attributed responsibility for the character’s actions to his personality traits. These findings could be viewed as contrasting with psychological research suggesting that respondents should have distanced themselves from the violent protagonist rather than identifying with him, and with Iyengar’s (1991) expectation that more personalized episodic framing would be associated with attributing responsibility to the protagonist.

This study aims to analyze how strategic management in the Firta Collection Boutique to develop its business, especially in providing services to customers. The method used in this research is a qualitative method that includes Marketing Mix (4P Analysis) and SWOT Analysis, to find out what external factors are opportunities or threats to the Firta Collection Boutique. The results of the study show that the strategies adopted by the Firta Collection Boutique are still inappropriate and need to use other strategies. Changes in the external environment have continued to increase so that it is an opportunity and anticipates threats by utilizing strengths and minimizing weaknesses by innovating and improving approaches and gaining customer trust in product quality, in order to compete in the fashion sector.

The paper is devoted to the role of the global financial market in the development of Russian big business. It proves that terms and standards posed by this market as well as opportunities it offers determine major changes in Russian big business in the last three years. The article examines why Russian companies go abroad to attract capital and provides data, which indicate the scope of this phenomenon. It stresses the effects of Russian big business’s interaction with the world capital market, including the modification of the principal subject of Russian big business from integrated business groups to companies and the changes in companies’ behavior: they gradually move away from the so-called Russian specifics and adopt global standards.

The article considers current problems of Russia´s science. Special attention is paid to external factors that negatively influence its effectiveness including considerable lag in public management sector. The issues of opposing higher education sector to the Russian Academy of Sciences (RAS) are also discussed. A number of indicators of the Russian science and its academic sector effectiveness are presented. The expediency of comparing scientific results with R&D expenditures is shown. The problems connected with using bibliometric methods are discussed. Special attention is paid to the necessity of preserving and further developing Russian science including RAS.

Among the compounds able to efficiently inhibit the amyloid aggregation of proteins and decompose the amyloid aggregates that cause neurodegenerative diseases, of particular interest are dendrimers, which represent individual macromolecules with the hypercrosslinked architectures and given molecular parameters. This short review outlines the peculiarities of the antiamyloid activity of dendrimers and discusses the effect of dendrimer structures and external factors on their antiamyloid properties. The potential of application of dendrimers in further investigations on the aggregation processes of amyloid proteins as the compounds that exhibit the remarkable antiamyloid activity is evaluated.

Blocking is undesired adhesion between two surfaces when subjected to pressure and temperature constraints. Blocking between two coated paperboards in contact with each other may be caused by inter-diffusion, adsorption, or electrostatic forces occurring between the respective coating surfaces. These interactions are influenced by factors such as the temperature, pressure, surface roughness, and surface energy. Blocking potentially can be reduced by adjusting these factors, or by using antiblocking additives such as talc, amorphous silica, fatty acid amides, or polymeric waxes. We developed a method of quantifying blocking using a rheometer. Coated surfaces were put in contact with each other with controlled pressure and temperature for a definite period. We then measured the work necessary to pull the two surfaces apart. This was a reproducible way to accurately quantify blocking. The method was applied to determine the effect external factors have on the blocking tendency of coated paperboards, i.e., antiblocking additive concentration, film thickness, temperature, and humidity.
