The materials of the scientific discussion contain basic ideas, pronounced by Russian and foreign participants in the International scientific discussion on the subject of “Communication regimes in Latvia, Lithuania and Estonia”. The discussion was held by the National Research Institute of Communication Development (НИИРК). The Study of communication regimes, held by НИИРК based on author’s methods revealed the following in Latvia, Lithuania and Estonia: rigid regulation of all segments of communication and information content , bodies of self-government included ( having the opportunity to align contacts independently, for example, in the border areas), control over the communication participants taken at random, under the pretext of providing informational security, especially mass media and NGO; strive for the consolidation of the society on the basis of articulating of threats to the national identity and threats to ethnic national self-consciousness; dominating of the Russian threat to national security in information discourse; conscious policy of narrowing the Russian language informational, educational and socializing space; incomplete inclusion in the European information discourse and selective compliance with the principles of the EU relative to communication and information (codex of practices relative to misinformation); the beginning of the compaction of communication space by alternative actors, who appeared as a result of mistrust for the acting government and as a result of impossibility to realize their needs. In the course of the debates it was discussed: institutionalization of the countries communication regimes: role of historically shaped and contemporary practices in Latvia, Lithuania, Estonia; actors models of communication regimes in Latvia, Lithuania, Estonia; role of political institutes, mass media, institutes of civil society and business in shaping communication regimes; peculiarities of communication regimes relative to separately taken groups of the population, mass media, neighboring countries.

In metal-mechanic industry, lubricants are applied to improve products’ quality and tools useful life, while reducing friction and wear, also removing the generated heat during the material processing. Tribological evaluations are performed varying the water content of two widely used lubricants in automotive metal-forming operations. Evaluations are first performed to determine the optimal lubricant dilutions, followed by reinforcement of 2D-nanostructures of hexagonal Boron Nitride (h-BN). Tribological characterization under extreme pressures (EP) are performed with a four-ball tribometer according to the Institute for Sustainable Technologies –National Research Institute (ITeE-PIB) Polish method under scuffing conditions. The optimized concentrations are determined for Ecodraw and Montgomery lubricants, representing a 28% and 3% improvement in pressure loss limit at 1:8 and 1:6 concentrations, respectively. Block-on-ring tribotest is used to determine the coefficient of friction (COF) of the optimized lubricant dilutions and h-BN nanolubricants, which represent ~10% improvement. These results could be attributed to diverse factors such as a layering mechanism of the 2D nanostructures, soft van der Waals forces between 2D h-BN layers, and the deposition of h-BN on the worn surface, decreasing the shearing stress and COF. Finally, thermal conductivity evaluations showed an enhancement by 30% and 15% with addition of h-BN, demonstrating the potential of 2D nanostructures for improving the efficiency on antiwear and thermal transport.

Western Prasat Top is located in the south-west quadrant of Angkor Thom. The Central, South, and North Sanctuaries, and the uposathāgāra are divided by sīmā stones and, along with a laterite boundary, form the temple precinct. In order to study the history of Western Prasat Top, the Nara National Research Institute for Cultural Properties (NABUNKEN), in collaboration with the Apsara National Authority (APSARA), began surveying in 2003. Our discoveries from the North Sanctuary have contributed new and important evidence to understanding the history of the late Angkor period. We will discuss this unearthed evidence from the perspectives of archaeology, archaeological science and iconography. ប្រាសាទតុបខាងលិចសិ្តជៅទិសនិរតីននប្រាសាទរាយនព័ អតីតប្ក្រុងអង្គរធំ។ បរជិ េណប្រាសាទតុបមានតួបម៉ ក្ណ្តា ល ខាងត្បូង និងខាងជ􀈹ើង ប្ពមទាងំ ជ􀈳ឿនឧជរាសថ (ប្ពរះេហាិ រ) ដែលមានសន្លឹក្សីមា៉ ថ្មភក្ជ់ ្្ រះមានប្រាបំ ីទិសជ􀉒ើយមានជាក្ប្មាលរបងប្ពំថ្មរាយជប្ក្ៀមពទព័ ្ធ􀈹ុំេញិ ដែលបជងើតក រានជាទប្មងប្់ រាសាទ។ ជែើម្សី ិក្សា􀈳្រះៗពីប្បេតិប្តា រាសាទតុបខាងលិច េទិ យាសា្ នប្សាេ ប្ជាេជាតិណ្រ៉សប្មាបស់ ម្តិេតា ប្ធម ៌ (NABUNKEN) រានស􀉒ការជាមយួ អាជាញា ធរជាតិអប្សរ ដែ លរានចាបជ់ ្ើមតា ជធើក្វ ិច្ចស􀉒ប្បតិបតិកាតា រប្សាេប្ជាេជៅឆ្នា ំ ២០០៣។ ការសិក្សាប្សាេប្ជាេជនរះរក្ជ􀈵ើ ញេតុ្មយួ ចំនួនជៅតួបម៉ ខាងជ􀈹ើងដែលជាភសុតាតាងែស៍ ំខាន ់ ក្ុងនា ការរមួ ចំដណក្រក្ជ􀈵ើញរបក្គំជ􀉒ើ ញថី្ម និង ជែើម្ដី សវងយល់អំពីប្បេតិសាតា សសតានាសមយព័ ចុងជប្កាយននអាណ្ចប្ក្អង្គរ។ ជយើងនលឹងពិ្ក្្ សាអំពីភសុតាតាងទាងំ អមបាលមានដែលរានរក្ជ􀈵ើញឲ្យរានសុី􀈹ជប្រៅ ជៅជលើទស្សនៈននបុរណេទិ យា,េ ទិ យាសាសសតាបុរណេទិ យា និងជទេក្ថា។

Jelen tanulmány a nemzetközi tudományos versenyképességet méri a rendészettudományi profillal rendelkező intézmények körében. A nemzetközi tudományos szemléletváltásba jól illeszkedik az egyre kiéleződő verseny, mind a kutatók egyéni, mind az intézmények és országok szintjén. A nemzetközi tudományos szemléletváltás legjelentősebb folyamata a tudományos munka „piacosodása”, melynek keretében a szerzők megélhetésüket kötik a kutatómunkához. A folyamat jelentős eleme a nemzetközi rangsorok, különösen a jelen tanulmányunk vizsgálati kereteit adó nemzetközi egyetemi rangsorok felértékelődése a tudományos teljesítmény mérhetővé válásával. A vizsgálatba hat intézményt vontunk be: Central Police University, College of Policing, Israel Police, National Research Institute of Police Science, Royal Canadian Mounted Police, Shandong Police College. Eredményeink azt mutatják, hogy a vizsgált intézmények összes publikációinak 79%-a folyóiratközleményként jelenik meg, ezt a konferenciaközlemények és review típusú közlemények követik. A társadalomtudományi közlemények 266 darabbal a hatodik legaktívabb tudományterületként jelennek meg a publikációs tevékenységben, melyet az orvostudományi közlemények vezetnek 1088 közleménnyel. A publikációs aktivitást tekintve megállapíthatók a bevont szerzők körében legnépszerűbb tématerületek is, melyet a „Gyilkosság; Sorozatgyilkos; Gyilkosok” tématerület vezet. A társszerzői hálózat elemzésekor egy igen aktív és erőteljes tudományos együttműködés rajzolódik ki a vizsgált intézmények szerzői körében. Az ehhez a társszerzői hálózathoz való csatlakozás a hazai, főleg Nemzeti Közszolgálati Egyetem központú rendészettudományi kutatók számára prioritás a nemzetközi versenyképesség eléréséhez.

I have been working on research in data management for the last 40 years. I like my job and my research institution (Inria, the French national research institute for computer science), which have offered me great opportunities to learn a lot, do good work, get to know smart and nice people and overall feel useful. However, since the early days of my mid-career, the research environment, including academia and industry, has certainly become more complex, making the move from junior (or pre-tenure) researcher to senior researcher quite challenging. Based on my experience, I review some of the main questions and challenges and give some hints on how to deal with them. I'll sometimes use stories and anecdotes to illustrate the point.

This study examined the nature of postharvest losses of rice in Makurdi Local Government Area of Benue State. The study specifically examined the stages of the postharvest losses of rice. A sample of 399 rice producers were drawn in Makurdi using the Taro Yamane formula. Quantitative data collection techniques were used to elicit information from respondents. The findings from the study revealed that, the nature postharvest losses of rice start from harvest to consumption stage, with threshing recording the highest loss of 27%. However, the total losses from all the stages are between 37%-40%. The study therefore recommended sensitization of farmers through the relevant agricultural agencies on postproduction of rice, establishment of reserves for the preservation of rice, linking farmers with agro-processing equipment available in state or those at national research institute at an affordable price, plus farmers to take advantage of cooperatives to benefit from agricultural projects establish by the government.

Natural gas is the basic fossil fuel in the global economy. According to the information published by Polskie Górnictwo Naftowe i Gazownictwo SA in the document Company Presentation, gas consumption in 2018 amounted to 19.7 billion m3. Due to the fact that the domestic reserves of natural gas are increasingly depleted, the demand for natural gas will be satisfied by growing imports. Balancing gas demand will require precise knowledge of the volume of domestic natural gas production. On the other hand, every year the Polish Geological Institute – National Research Institute (PIG – BIP) publishes Balance of mine resources in Poland. According to the publication on the state of resources as of December 31, 2018, 298 natural gas fields have been documented in Poland, 5 in the Baltic Sea region, 35 in Carpathians, 105 in Carpathian Foreland and 153 in Polish Lowland. The balance presented by PIG – BIP for 2018 showed the state of natural gas contingent resources in the amount of 139.93 billion m3 (total balance resources). The volume of industrial reserves of natural gas deposits as at December 31, 2018 was 66.64 billion m3. It should be emphasized that all data published in the Balance of mine resources in Poland are given in normal cubic meters. Therefore, the data published by PIG – BIP do not take into account the actual calorific value of natural gas produced from various fields. Starting from 2014, the basic accounting unit in Poland is the energy unit (kWh). Due to the introduction of the settlement in energy units, the value of 1 m3 of nitrogen-rich gas produced from the fields located in the Lowland region is lower than the value of gas produced from the Carpathian Foreland fields and the Carpathians. The average calorific value of gas produced from the Lowland fields is about 8.0 kWh/m3, while the average calorific value of gas produced from the rest of the Foreland is about 11.2 kWh/m3. The main goal of this article was to make a forecast of gas production from domestic deposits based on the Balance of mine resources in Poland published by the Polish Geological Institute –National Research Institute. The forecast of gas extraction from domestic deposits was made for the years 2020–2030. The production forecast was prepared for each gas-bearing region separately. In order to adjust the reported volumes to the applicable energy units, the gas production forecast for the Lowland fields was converted into high-methane gas production.
