The presence of tetrahedral aluminum was the main factor contributing to the rapid synthesis, which also promoted the transformation from octahedral aluminum to tetrahedral aluminum structure unit, and further accelerated the formation of SSZ-13.

Maintenance of the individual patterns of gene expression in different cell types is required for the differentiation and development of multicellular organisms. Expression of many genes is controlled by Polycomb (PcG) and Trithorax (TrxG) group proteins that act through association with chromatin. PcG/TrxG are assembled on the DNA sequences termed PREs (Polycomb Response Elements), the activity of which can be modulated and switched from repression to activation. In this study, we analyzed the influence of transcriptional read-through on PRE activity switch mediated by the yeast activator GAL4. We show that a transcription terminator inserted between the promoter and PRE doesnt prevent switching of PRE activity from repression to activation. We demonstrate that, independently of PRE orientation, high levels of transcription fail to dislodge PcG/TrxG proteins from PRE in the absence of a terminator. Thus, transcription is not the main factor required for PRE activity switch.

In the paper the nature of Russian corruption is considered along the lines proposed by D. North, J. Wallis, and B. Weingast. The author considers patron-client networks as basic political and economic actors of the limited access order. The redistributive rent allocated within patron-client networks is not a corruption phenomenon. The main factor that is able to destroy patron-client networks and autonomous centers of power is the right to contestation (liberalization) according to R. Dahl. Realization of that right together with the right to participate in political life enables transition to the open access society.

The modern approaches and mechanisms of managing the organization knowledge being now the main factor of innovation processes are observed in the article. Functioning of such mechanisms is not simple and needs outsourcers in education and consulting. In order to make the management effective the interaction of the company with the outsourcer should sustain the process of permanent knowledge circulation.

The overall dimensions and mass of wind power units with capacities larger than 10 MW can be improved and their cost can be decreased by developing and constructing superconducting synchronous generators. The article analyzes foreign conceptual designs of superconducting synchronous generators based on different principles: with the use of high- and low-temperature superconductivity, fully superconducting or only with a superconducting excitation system, and with the use of different materials (MgB2, Bi2223, YBCO). A high cost of superconducting materials is the main factor impeding commercial application of superconducting generators. In view of the state of the art in the technology for manufacturing superconductors and their cost, a conclusion is drawn, according to which a synchronous gearless superconducting wind generator with a capacity of 10 MW with the field winding made of a high-temperature superconducting material (MgB2, Bi-2223 or YBCO) with the «ferromagnetic stator — ferromagnetic rotor» topology, with the stator diameter equal to 7—9 m, and with the number of poles equal to 32—40 has prospects for its practical use in the nearest future.

A Pdᴵᴵ-catalyzed, ligand-enabled gamma-C(sp3)–H arylation of free primary aliphatic amines and amino esters without using an exogenous directing group is reported. This reaction is compatible with unhindered free aliphatic amines, and it is also be applicable to the rapid synthesis of biologically and synthetically valuable unnatural α-amino acids. Large scale synthesis is also feasible using this method.<br>

The article deals with the skill of using symbols and emblems in the poetry of the poetess Halima Khudaiberdieva. Poetry is one of the highest forms of art, and its perception requires a high level,high taste, deep understanding from the reader. The article lists important aspects of the requirements for an original poem. It is emphasized that the main factor of mystery in the poem are symbols and allusions. Some examples from the poems of the poet are given and analyzed. Through this, an attempt was made to explore the artistic representations of the poet’s poetry

According to the National Energy Balance report released by the Energy Commission of Malaysia in 2016, the residential sector uses 21.6% of the total energy in Malaysia. Residents waste energy through inefficient energy consumption and a lack of awareness. Building occupants are considered the main factor that influences energy consumption in buildings, and to change energy consumption on an overall scale, it is crucial to change individual behaviour. Therefore, this study focused on analysing the energy consumption pattern and the behaviour of consumers towards energy consumption in their homes in the residential area of Batu Pahat, Johor. A self-administrated questionnaire approach was employed in this study. The findings of this study showed that the excessive use of air conditioners was a significant factor in the increasing electricity bills of homeowners as well as the inefficient use of electrical appliances. Also, this study determined the effect of awareness on consumer behaviour. This study recommends ways to help minimise energy consumption in the residential area.
