The value of tourist destinations in the management of regional development

Ericsson’s Region IPR & Licensing (RIPL) receives about 3000 thousands Invention Disclosures (IvDs) every year submitted by researchers as a result of their R&D activities. To decide whether an IvD has a good business value and a patent application should be filed; a rigorous evaluation process is carried out by a selected Patent Attorney (PA). One of most important elements of the evaluation process is to find prior art similar, including similar IvDs that have been evaluated before. These documents are not public and therefore can’t be searched using available search tools. For now the process of finding prior art is done manually (without the help of any search tools) and takes up significant amount of time. The aim of this Master’s thesis is to develop and test an information retrieval search engine as a proof of concept to find similar Invention Disclosure documents and related patent applications. For this purpose, a SOLR database server is setup with up to seven thousand five hundred (7500) IvDs indexed. A similarity algorithm is implemented which is customized to weight different fields. LUCENE is then used to query the server and display the relevant documents in a web application

Состояние Шапшальского центра оледенения (Восточный Алтай) в 2015 году

Catalogues and maps of glaciers (for 2015) of Shapshal Glacier Center, located in the eastern part of the Russian Altai, have been created based on the first field glaciological observations and space images interpretation. In total 123 glaciers with the total area of 14.07 km2 have been allocated. In comparison with the data from the Glacier Inventory of the USSR (1955–1965), the total area of the glaciers has decreased by more than 2 times. The lower limit of glacier development is 2475 m, to the south-east of the region it rises by 1 km, the height of the firm line rises from 2860 m to 3460 m, respectively. Small glaciers prevail (70% of glaciers have an area less than 0.1 km2, the area of the largest glacier is 0.9 km2). In terms of quantity and area, cirque glaciers predominate, there are no valley glaciers. The largest numbers of glaciers have northern and northeastern exposure, with the largest areas of glaciers concentrated on the north-eastern slopes. The highest glaciation intensity has been detected on the eastern slope of the Skalistiy Ridge and the northeastern slope of the southern part of the Shapshalsky Ridge in the upper reaches of the Chon-Khem River, which are optimal for glaciers by a combination of mountain heights and position relative to moisture-bearing atmospheric flows. To the west of these areas, intensity of glacierization decreases due to lower mountain heights, to the east – due to lower precipitation. In general, with low (0.1 km−1 and less) intensity of glacierization, the Shapshal Centre is an area of dispersed glaciation, most glaciers of which are on the verge of disappearance.Получены новые карты и каталог ледников мало исследованного Шапшальского центра оледенения на Восточном Алтае. По состоянию на 2015 г. здесь насчитывалось 123 ледника суммарной площадью 14,07 км2. По сравнению с данными 1955–1965 гг. суммарная площадь ледников сократилась более чем вдвое. Преобладают малые каровые ледники северо-восточной и северной экспозиций. Площади ледников и интенсивность оледенения убывают с северо-запада на юго-восток

PROCESSING OF SULFURIC-ACID SOLUTIONS OF URANIUM IN SITU LEACHING WITH HIGH CONTENT OF CHLORINE

The processing of sulfuric-acid solutions after uranium in situ leaching with high content of chlorine was studied. The precipitation by different methods allows to obtain uranium con-centrates with high quality according to ASTM C967-13

Сокращение ледников Восточного Алтая (Шапшальский центр) после максимума малого ледникового периода

Based on the analysis of remote data and field observations, we reconstructed the glaciation of the Shapshal Center (Eastern Altai) for the maximum of the Little Ice Age (LIA) and by the state of the glaciers as of 2001. At the maximum of the LIA, glaciation was represented by 358 glaciers with a total area of 84.43 km2. It was found 87% reduction of the total area of glaciers in the interval from the LIA maximum to 2015. During the reduction, valley glaciers disintegrated and glaciers in the Kargy River basin disappeared. The moraines of the LIA have low lake coverage (0.17% of area), therefore a probability of their breakthrough is low. We obtained data on the retreat of the Mushtuk Glacier (№ 78), the largest one of the Shapshal center, in five time slices from the LIA maximum. The highest retreat rates were reconstructed in the interval 1989–2001, but in the interval 2010–2016 the average rates decreased to 5 m/year. Changes in the mass balance index of the Mushtuk Glacier between from 1961 to 2018 were calculated. A sharp decrease in the mass balance in the 1990s and stabilization of values at a low level after 2001 were found. According to the calculations, the response time of the Mushtuk Glacier was about 9 years. If the current climatic conditions persist, there is reason to assume stabilization of glaciers in the coming years.Реконструированы ледники малоисследованного Шапшальского центра оледенения на Восточном Алтае в максимум малого ледникового периода, проанализирован характер их последующего сокращения. Детально рассмотрено сокращение крупнейшего ледника Шапшальского хребта по пяти временным срезам c 1955 по 2019 г. Проведены расчёты индекса баланса массы ледника и времени его климатического отклика

Evolution of microstructure and crystallographic texture during dissimilar friction stir welding of duplex stainless steel to low carbon-manganese structural steel

Electron backscattered diffraction (EBSD) was used to analyze the evolution of microstructure and crystallographic texture during friction stir welding of dissimilar type 2205 duplex stainless steel (DSS) to type S275 low carbon-manganese structural steel. The results of microstructural analyses show that the temperature in the center of stirred zone reached temperatures between Ac 1 and Ac 3 during welding, resulting in a minor ferrite-to-austenite phase transformation in the S275 steel, and no changes in the fractions of ferrite and austenite in the DSS. Temperatures in the thermomechanically affected and shoulder-affected zones of both materials, in particular toward the root of the weld, did not exceed the Ac 1 of S275 steel. The shear generated by the friction between the material and the rotating probe occurred in austenitic/ferritic phase field of the S275 and DSS. In the former, the transformed austenite regions of the microstructure were transformed to acicular ferrite, on cooling, while the dual-phase austenitic/ferritic structure of the latter was retained. Studying the development of crystallographic textures with regard to shear flow lines generated by the probe tool showed the dominance of simple shear components across the whole weld in both materials. The ferrite texture in S275 steel was dominated by D 1, D 2, E, E¯ , and F, where the fraction of acicular ferrite formed on cooling showed a negligible deviation from the texture for the ideal shear texture components of bcc metals. The ferrite texture in DSS was dominated by D 1, D 2, I, I¯ , and F, and that of austenite was dominated by the A, A¯ , B, and B¯ of the ideal shear texture components for bcc and fcc metals, respectively. While D 1, D 2, and F components of the ideal shear texture are common between the ferrite in S275 steel and that of dual-phase DSS, the preferential partitioning of strain into the ferrite phase of DSS led to the development of I and I¯ components in DSS, as opposed to E and E¯ in the S275 steel. The formations of fine and ultrafine equiaxed grains were observed in different regions of both materials that are believed to be due to strain-induced continuous dynamic recrystallization (CDRX) in ferrite of both DSS and S275 steel, and discontinuous dynamic recrystallization (DDRX) in austenite phase of DSS

SULFURIC ACID LEACHING OF URANIUM FROM SOLID RADIOACTIVE WASTE OF URANIUM PRODUCTION

The process of leaching of uranium from radioactive waste using sulfuric acid is investi-gated. It has been established that with an increase in the process temperature and an excess concentration of acid in the leach solution, the degree of uranium extraction increases to 98%
