Fluorite-structured oxides constitute an important class of materials for energy technologies. Despite their high level of structural symmetry and simplicity, these materials can accommodate atomic disorder without losing crystallinity, making them indispensable for uses in environments with high temperature, changing chemical compositions, or intense radiation fields. In this contribution, we present a set of simple rules that predict whether a compound may adopt a disordered fluorite structure. This approach is closely aligned with Pauling’s rules for ionic crystal structures and Goldschmidt’s rules for ionic substitution.

The accretion disks are now supposed to be the main driving source of the active astrophysical phenomena. Even the electron-positron pair plasma will be created at the surface of the sufficiently luminous disk. While the effect of radiation drag which causes in the intense radiation fields around the accretion disk is examined recently. Then, we numerically consider the radiative accelerated pair-winds, which blow off from central luminous accretion disk surrounding a black hole, taking into account radiation drag of the order of v/c.

A high level of acceptance and adoption is necessary to facilitate the widespread utilization of renewable energy technologies for cooking, as such utilization is essential for displacing the population’s massive dependence on fossil fuels and solid biomass. Economic and demographic aspects have been the focus of recent literature in exploring the adoption phenomenon of biogas technology. However, literature to date has given little attention to the behavioral factors and the perceptions of the end-users. Our study does not only include behavioral factors, but it employs a hybrid model to explore the continued attentions of users based on their post-adoption beliefs and performance expectations. Using a survey conducted in Pakistan in 2017, the study conducts a multivariate analysis through structural equation modeling to measure the effect of pre- and post-adoption beliefs and expectation on adoption and the continuing intention of households towards biogas technology. Results show that the acceptance of the households towards biogas technology is highly influenced by their perceptions on the benefits, as well as their trust in the technology. The perceived cost and risk attached to the technology are found to be negatively correlated with the acceptance. Households’ intentions to continue the use of biogas technology is highly influenced by the satisfaction level of the users of biogas technology. With the integrated model of adoption and continuation, the study illustrates the dynamic process in obtaining a deeper understanding of a user’s behavior to better formulate the policies for increasing the rate of technology adoption.

Case Data

Grounded in the dynamic capabilities perspective, our study addresses the question of how information technology outsourcing capabilities can interact with other IT strategic capabilities to enable organizational agility through the ongoing reconfiguration of IT solutions. To answer our question, we built on the notion of microfoundations that undergird the high-level dynamic capabilities of sensing, seizing, and reconfiguring. Adopting a theory elaboration approach, we studied the case of a firm evolving in a turbulent environment, which had outsourced the quasi-totality of its IT services and had a mature IT architecture. From the case data, we specify two types of microfoundations: repeatability-related microfoundations (i.e. processes) and ability-related microfoundations (i.e. IT department structure, skills, simple rules, and communications) that undergird either information technology outsourcing dynamic capabilities or IT architecture dynamic capabilities. We propose a model that outlines how the interaction between repeatability-related microfoundations, supported by ability-related microfoundations, enables the reconfiguration of IT solutions. Our study also elucidates how a firm can follow a logic of opportunity enabled by their IT outsourcing and IT architecture dynamic capabilities.

The radiative winds from a geometrically thin accretion disk are studied. The effect of radiation drag which causes in the intense radiation fields around the accretion disk is examined recently. Then, we numerically consider the radiatively-accelerated accretion-disk winds which consist of ionized gas particles, taking into account radiation drag of the order ofv/c.

Rolling Technology

The Institute of Metal Forming and Safety Engineering has developed technology for manufacturing grade X80 pipeline plates according to European standard EN 10208-2. Experimental chemical compositions ensuring a high level of yield strength have been developed. The article describes a method for selecting chemical composition [1]. The advancement of rolling technology takes much time and many calculations. Thus, using numerical simulations provides a possibility of a theoretical analysis of the plates made from new materials [4], [5]. Preliminary studies [1] have disclosed a large volume of deformations during the rolling process, which causes the distortion of rolls and generates heavy loads. For the theoretical analysis of rolling plates, Forge 2008® was used. The paper presents the obtained results of energy analysis and strength parameters displayed in Figure 1. The article considers a total amount of pressure on metal rollers and changes in the rolling moment.

The purpose of research focused on post-slaughter evaluation of meat productivity and meat quality the Kazakh White-headed breed when introduced into the diet of feed additives BioDarin. Presents the results of the control slaughter heifers 18 months old as well as the results of studies of morphological and chemical compositions of the carcass. The research was conducted post-slaughter evaluation of meat productivity and meat quality of heifers of Kazakh White-headed breed when introduced into the diet of feed additives BioDarin. Scientific and economic experiment was carried out on the basis of JSC AIC «Alga+» Tuimazinsk district of the Republic of Bashkortostan. For the experiment there were formed 4 groups of heifers of Kazakh white-headed breed: group I – control; group II heifers in addition to the basic diet received a feed additive in a dose of 0.5 kg per 100 kg of grain mixture, the animals of group III received 1 kg of the feed additive per 100 kg of grain mixture, peers IV groups received 1.5 kg of a grain mixture. Among the studied groups, heifers of the III experienced group receiving feed additive at a dose of 1.0 kg per 100 kg of grain mixture, had a high level of meat productivity. It was found that meat products of the best quality was got also from animals of group III.
