Gallery character of porous space in the STI-type zeolite structure

The existence of a specific gallery type of zeolite framework is confirmed. It has been found that similar to HEU-type, STI-type framework can be represented as a layered structure in which two impermeable to water molecules and exchange cations aluminum-silicate layers, separated by diortho-groups, confined gallery-type of porous free space, which is available for extra-framework components migration in all directions in the plane of the interlayer.

Interaction of the junction station of JSC «Russian railways» and non-public tracks of the oil refining complex

The article looks upon the features of interaction between the junction station of JSC «Russian Railways» and the tracks of non-public use of the oil refining complex. Technological maps of oil products loading are given, broken down into operations. The analysis of the main characteristics of the existing electric pumps of loading platforms is made with indication of types of cargo and selection of volumes of oil products loading on pointloading and gallery-type overpasses on certain days, taking into account loading in winter and summer periods. The order of loading time in winter and summer is determined. Based on the obtained data, a correlation analysis was performed to determine the statistical relationship between the two values. The identified dependencies allow the customer to predict and adjust production plans depending on the volume of loading by the nomenclature of oil cargo, the time of direct loading, the time of year, infrastructure factors and available technical means, and have reserves for improving the efficiency of interaction between the junction station and non-public tracks in terms of increasing the volume of loading of oil cargo in the future.

Pengaruh Model Pembelajaran Kooperatif Tipe Gallery Walk terhadap Hasil Belajar Pada Pelajaran Ekonomi Kelas X di SMA Negeri 1 Perbaungan

<p><em>This study aims to determine the effect of cooperative learning gallery walk type on learning outcomes of class X1 students in SMA Negeri 1 Perbaungan as well as an overview of student learning outcomes after the application of the learning model. This study used a Pre-Experimental Research Design The one Pretest-posttest Design group with a population of all students in class X1 Perbaungan 1 High School, amounting to 30 students. Because the population is relatively small so that samples are taken as much as 100% of the population, the number of samples in this study are 30 students (One Experimental Class). Data collection is done by using questionnaires, tests, observations, and documentation. The data analysis technique used is descriptive statistical analysis and inferential statistical analysis. The results showed that the walk gallery type cooperative learning model had a correlation of 0.782 in the medium category with a simple regression analysis equation Y = -12.507 +1.641X. The results of hypothesis testing with SPSS obtained tcount = 6.640 and ttable of 2.048 with a calculated value abel t table with a value of 6.640 </em>³<em>2.048 with a significance value of 0.000 so H1 is accepted and H0 is rejected, this indicates that the influence of the gallery walk type cooperative learning model on results studying class X1 Negeri 1 Perbaungan students. The magnitude of the contribution of the influence of the learning model is 61.2 percent, while 38.8 percent is influenced by other factors that have not been studied in this study.</em></p>

Shooting Galleries and HIV Disease: Variations in Places for Injecting Illicit Drugs

Three types of shooting galleries—places where people inject illicit drugs—are identified, based on the authority relations that organize them. Shooting gallery distribution within Chicago is linked to variations in neighborhood political economies. Risk for the transmission of human immunodeficiency virus (HIV) and the potential for risk reduction vary according to gallery type.
