under the Creative Commons Attribution 3.0 License.Historical literature may constitute a valuable
source of information to reconstruct sea-level changes. Here,
historical documents and geological records have been combined
to reconstruct Caspian sea-level (CSL) changes during
the last millennium. In addition to a comprehensive literature
review, new data from two short sediment cores were
obtained from the south-eastern Caspian coast to identify
coastal change driven by water-level changes and to compare
the results with other geological and historical findings.
The overall results indicate a high-stand during the Little Ice
Age, up to −21m (and extra rises due to manmade river
avulsion), with a −28m low-stand during the Medieval Climate
Anomaly, while presently the CSL stands at −26.5 m.
A comparison of the CSL curve with other lake systems and
proxy records suggests that the main sea-level oscillations
are essentially paced by solar irradiance. Although the major
controller of the long-term CSL changes is driven by climatological
factors, the seismicity of the basin creates local
changes in base level. These local base-level changes should be considered in any CSL reconstruction

Izteleuova: ORCID 0000-0002-7631-5223ENG: The purpose of the paper is to assess the competitiveness of road and rail transport for the transportation of perishable foods in the Republic of Kazakhstan. The study analyzed food consumption and production, as well as the transport network of the Republic of Kazakhstan. An assessment was made of the costs of transporting perishable foods by road, as well as by rail in railway cars and container trains. The modes of transportation were established, and it was found that the transportation of fresh food products in container trains is competitive with road transportation. The scientific novelty of the work is that it improves the method for assessing the competitiveness of road and rail transport for the transportation of fresh food products. The proposed method differs from existing ones in that it takes into account the loss of consumer value of food products over time while also considering the presence of competition by sources when choosing a type of transport. The practical value of the work is that it establishes the types of food products and directions of their transportation, the performance of which is advisable to carry out by container trains in the Republic of Kazakhstan.UKR: Метою роботи є оцінка конкурентоспроможності автомобільного та залізничного транспорту для перевезення швидкопсувних продуктів харчування в Республіці Казахстан. В ході дослідження було проаналізовано споживання та виробництво продуктів харчування, а також транспортну мережу Республіки Казахстан. Проведено оцінку витрат на перевезення швидкопсувних продуктів харчування автомобільним транспортом, а також залізничним транспортом у вагонах і контейнерних поїздах. Встановлено види перевезень і виявлено, що перевезення свіжих харчових продуктів у контейнерних поїздах є конкурентоспроможними порівняно з автомобільними перевезеннями. Наукова новизна роботи полягає в тому, що в ній удосконалено метод оцінки конкурентоспроможності автомобільного та залізничного транспорту при перевезенні свіжих харчових продуктів. Запропонований метод відрізняється від існуючих тим, що враховує втрату споживчої цінності продовольчих товарів з часом, а також наявність конкуренції за джерелами при виборі виду транспорту. Практична цінність роботи полягає в тому, що в ній встановлені види харчових продуктів і напрямки їх перевезень, виконання яких доцільно здійснювати контейнерними поїздами в Республіці Казахстан.Rzeszow University of Technology, Rzeszów, Poland; ALT University named after M.

Mechanical analysis of vibratory conveyor mechanism
No full textThe paper describes some of the basics of kinematics and dynamics of vibratory conveyor drive. Featured are dynamic modes of material that is being transported. Presented are the optimum material handling, and most rational mode. Introducing the empirical dependence transport speed as a function of angle bending conveyor, amplitude of oscillation of the transport container, the oscillation frequency excitation angle at which operates the actuating force and the coefficient mode of operation of the conveyor. Featured are some of the drive vibratory conveyors, and especially the operation of electromagnetic vibratory conveyor. In this paper is studied a vibratory conveyor that is placed on an elastic base. Using the closed contours method it was determined the system that needs to be solved to obtain graphical representation for the generalized coordinates determining the position of the mechanical system elements. The shaking conveyor represents the chase hanged or supported to the fixed section. The chase commits oscillating motions hereupon the cargo which is in the chase, migrates concerning to the chase. The nature of the flow and its parameters are determined by the nature of the oscillating committed by the chase. Justifying the dynamic parameters of the vibratory conveyor and a study of the strain-energy. Installation causes fluctuations fixed tray. Uniformly distributed load on the tray acts in each element of the mechanism. On the basis of the program MSC Adams investigated the strain-energy and kinetic-energy of each link mechanism with results and calculations

Intellectual Property Protection for AI-generated Creations Europe, United States, Australia and Japan.
No full textThis book explores the intersection between artificial intelligence and two intellectual property rights: copyright and patents. The increasing use of artificial intelligence for generating creative and innovative output has an impact on copyright and patent laws around the world. The book aims to map and analyse that impact. The author considers how artificial intelligence systems may aid, or in some cases substitute, human creators and inventors in the creative process. It is from this angle that the copyright and patent regimes in four jurisdictions (Europe, United States, Australia and Japan) are investigated in depth. The author describes how these jurisdictions look at works and inventions generated through a process where artificial intelligence is present or prevalent, and examines how copyright and patent regimes should adapt to the reality of artificially intelligent creators and inventors.As the use of artificial intelligence to generate creative and innovative products becomes more common, this book will be a valuable resource to researchers, academics and policy-makers alik
