Одной из особенностей государственного регулирования земельных ресурсов является установление ограничений в их использования. Это необходимое условие для соблюдения экологических и градостроительных норм, интересов общества и хозяйствующих субъектов. В связи с чем, следует говорить об актуальной задачи идентификации таких объектов, и, что самое главное, организации системы контроля за изменением их границ. Для Российской Федерации, несмотря на наличие огромных территорий, такие задачи актуальны для земель находящихся в интенсивном обороте и использовании. Современные методы получения материалов и данных об объектах местности, возможность их периодического обновления позволяю с максимальной оперативностью и минимальными затратами выявлять такие изменения. В данном исследовании продемонстрированы методы получения таких материалов и данных на примере объектов водного фонда, их значимость для установления ограничений в использовании прибрежных территорий. Также затронуты проблемы обновления картографической основы. Выявлены проблемы связанные с отсутствием стабильно работающей системы актуализации и верификации пространственных данных топографических карт различных масштабов. Хотя отчасти, такие процедуры, возможно, было бы, реализовывать на основе автоматизированных алгоритмов дешифрирования объектов местности. Тем самым, в целом, следует говорить о необходимости разработки и создания системы мониторинга границ природных и антропогенных объектов и явлений.
One of the features of state regulation of land resources is the establishment of restrictions in use. This is a requirement for compliance with environmental and planning regulations, social interests and business entities. In this connection, the identifi cation and documentation of such land resources is an essential task. In cases of constantly changing objects, the implementation of a system for monitoring the dynamic of their borders is important. Despite the existence of huge territories, land monitoring issues are relevant for the lands that are in intensive circulation and use in the Russian Federation. Modern methods based on remote sensing data of the Earth, their timely updating allow one to identify terrain feature changes at low cost and effi ciency. Methods of obtaining remote sensing data exemplifi ed be water resources, their importance for the establishment of restrictions in the use of coastal areas are demonstrated. The challenges of updating the cartographic base are considered in this article. Problems were identifi ed related to the lack of a stable system of updating and verifi cation of spatial data of topographic maps of different scales. Therefore, it is necessary to develop and establish a system for monitoring the changing boundaries of natural (anthropogenic) objects and activities on the land surface.

Представлены предварительные результаты анализа сейсмологической базы данных о временах вступлений сейсмических волн землетрясений. Показано, что соотношение между наблюденными (в интервале эпицентральных расстояний до 100 км) и теоретическими (рассчитанными в одномерной модели коры) временами пробега волн на северо-востоке Байкальского рифта характеризуется невязками, достигающими 34 с. Основная причина таких расхождений определяется трехмерной неоднородностью коры и зависимостью от глубины гипоцентров. Цель работы заключается в разработке методики составления априорной трехмерной модели среды, которая позволит получить более определенные сведения о распределении глубины очагов землетрясений и их связи с тектоникой земной коры рифтовой зоны.
The preliminary results of the analysis of the seismological database on the times of seismic waves of earthquakes are presented. It is shown that the difference between the observed (in the interval of epicentral distances up to 100 km) and theoretical travel time curves (calculated in a one-dimensional model of the crust) in the North-East of the Baikal rift is characterized by residuals reaching 34 s. The aim of the work is to develop a methodology for compiling a priori three-dimensional model of the environment for more reasonable information about the earthquake foci distribution and their relationship with the tectonics of the rift zone earths crust.

Переписка двух видных деятелей Русской Православной Церкви велась в 1873-1875 гг., когда о. Леонид занимался составлением Главной Описи обители, включавшей описи ее церквей, ризницы и книгохранилища. Протопресвитер Димитрий, настоятель Успенского собора Московского Кремля, проверял эту работу как член Конторы Святейшего Синода. Его письма свидетельствуют о внимательном, вдумчивом отношении к документам, представлявшим собой подробный реестр монастырского имущества. Замечания протопресвитера, отраженные в переписке, помогли усовершенствовать структуру Описи, которая до настоящего времени остается эталонным образцом для аналогичных исторических источников. Вместе с тем переписка содержит подробности жизни и служения о. Димитрия. Эти детали характеризуют личность протопресвитера, впитавшую лучшие черты русского православного духовенства XIX столетия.

Published: March 2022

Liquid smoke has been successful pabricated from mangrove Avicennia alba shell by pyrolysis method at a temperature of 400℃ for 3 hours. Liquid smoke was purified by adsorption using activated kaolinite as adsorbent. The test results showed that activated kaolinite could bring down the rancidness to become odorless and the color of liquid smoke from dark chocolate to gray colour. The composition of the liquid smoke compound was determined by using the Gass Chromatography-Mass Spectrophotometer (GC-MS) consists of 2-propanone (CAS) acetone 25.79% and furan, tetrahydro- of 10.37% and carbamic acid, monoammonium salt (CAS) ammonium carbamate of 58.46% . The LC50 value of pure liquid smoke ranging from 1000 ppm is an indication that it is not toxic and safe to use for food preservation. Activity test against the inhibition of microbial growth in fish meatballs, showed that ability. The higher the concentration of liquid smoke, the better the inhibition of microbial growth. Based on the results, it can be concluded that the liquid smoke produced from mangrove Avicennia alba shell purified by the activated kaolinite is very promising as a foodstuffs preservative

Photodegradation of phenol on TiO2-pillared-kaolinite was observed. Pillarization of kaolinite was conducted through intercalation of polyoxotitanium sol into clay suspension followed by calcination giving TiO2-kaolinite which showed an increase in specific surface area and total pore volume compared with the kaolinite. The analysis of XRD demonstrated no significant change on d-space of second order of kaolinite structure associated with 2q 26.61°, but diffractions with regard to 2q 25.3° and 48.0° interpreted for TiO2 anatase were seen on the diffractogram of TiO2-kaolinite. The significant decrease of phenol concentration was observed in the presence of both kaolinite and TiO2-kaolinite under UV illumination (hn ³ 365 nm) compare with the photoreaction without the kaolinite materials however the degradation rate of phenol on TiO2-kaolinite was faster than that on the kaolinite-only where 50% of phenol was consumed after 45 minutes of reaction. Kinetic study showed the photoreaction of phenol on TiO2-kaolinite follows the first order reaction with the reaction rate constant of 1.8 x 10-2 min-1.
