Abstract
This paper presents a technique of controlling the process of oil filling of polymer and composite materials, which allows automated determination of volumetric heating of a polymer or composite sample for the purpose of drying. The differentiation of the obtained results, presented in graphical form, made it possible to quickly analyze the dynamics of temperature changes in the thickness of the material, the change of which determines the rates and time of impregnation to a certain depth of the body of the polymer or composite sample in figure 1. According to the developed methodology, studies of the impregnation of the oil filler of a mixture of M8-B motor oil and hexane were carried out. For each experiment, time dependences of the impregnation rate were obtained. Based on the work carried out, the optimal proportion of a mixture of hexane and engine oil and the most favourable temperature conditions were determined. At the end of the research, the assumption about the possibility of using this technique for the purpose of its industrial use in the technology of oil filling of antifriction products made of polymer and composite materials was confirmed.

Abstract
The use of advanced simulation has become increasingly more important in the planning, design, and assessment phases of future fusion plasma diagnostics, and in the interpretation of experimental data from existing ones. The design cycle of complex reflectometry systems, such as the ones being planned for next generation machines (IDTT and DEMO), relies heavily on the results produced by synthetic diagnostics, used for system performance evaluation and prediction, both crucial in the design process decision making. These synthetic diagnostics need realistic representations of all system components to incorporate the main effects that shape their behavior. Some of the most important elements that are required to be well modelled and integrated in simulations are the wave launcher structures, such as the waveguides, tapers, and antennas, as well as the vessel wall structures and access to the plasma. The latter are of paramount importance and are often neglected in this type of studies. Faithfully modelling them is not an easy task, especially in 3D simulations. The procedure herein proposed consists in using CAD models of a given machine, together with parameterizable models of the launcher, to produce a description suited for Finite Difference Time Domain (FDTD) 3D simulation, combining the capabilities of real-world CAD design with the power of simulation. However, CAD model geometric descriptions are incompatible with the ones used by standard FDTD codes. CAD software usually outputs models in a tessellated mesh while FDTD simulators use Volumetric Pixel (VOXEL) descriptions. To solve this interface problem, we implemented a pipeline to automatically convert complex CAD models of tokamak vessel components and wave launcher structures to the VOXEL input required by REFMUL3, a full wave 3D Maxwell FDTD parallel code. To illustrate the full procedure, a complex reflectometry synthetic diagnostic for IDTT was setup, converted and simulated. This setup includes 3 antennas recessed into the vessel wall, for thermal protection, one for transmission and reception, and two just for reception.

Abstract
Rock-Eval pyrolysis and kinetics are widely used to evaluate hydrocarbon generations. Due to heterogeneity of shale, even a series of samples come from the same drill core rock will have a wide range of total organic carbon (TOC). It is important to select propriate TOC samples to acquire Rock-Eval and kinetic parameters. However, influence of different TOC levels to Rock-Eval and kinetics are still not well known. In this study, different samples with different TOC of 3.87%, 13.59%, 18.17%, 23.93%, 25.93% and 35.35% taken from one drill core were selected and analysed. And all samples are prepared to 4mm grain-size samples for Rock-Eval pyrolysis to reflect hydrocarbon generation and expulsion in realistic conditions. The results show that generation rate gradually decreases from 0.0064 to 0.0053 mg/g·s−1 when TOC increase from 13.59 to 35.35%. And the samples with 35.35% and 25.53% TOC show highest transformation ratio, while the samples with 3.87% show the lowest transformation ratio. In addition, the samples with 3.87% TOC only shows one main activation energy peak (56Kcal/mol). Yet the samples with 35.35% TOC shows three activation energy peaks (53, 54, 56Kcal/mol). With increasing of TOC levels of samples, percentage of main activation energy decrease from 69.43 to 25.96 and 29.62%. Therefore, generation rate of high TOC shale will decrease and transformation ratio will increase. And hydrocarbon generation and expulsion of high TOC samples need lower action energies.

Abstract
The agribusiness sector as the basis of regional development and economic development is an important factor in improving the welfare of rural communities especially in border regions Indonesia-Malaysia. The amount of potential economic based on natural resources in the border regions is not matched the ability of human resources in term of utilization and management This study aims to improve the Krayan rice farming entrepreneurship performance. In the data collection, a total sample of 200 farmers purposive sampling method were used. The model based collected data was developed using the structural equation model and assisted by the AMOS program. The results showed that overall, the entrepreneurial intention model fulfilled the norms of the model fit (Chi-Square: 68.333; Probability: 0.398; RMSEA: 0.013; GFI: 0.956; AGFI: 0.930; CFI: 0.998) which means the developed model was appropriate with the existing empirical conditions. The entrepreneurship variable has a great influence in shaping the performance of farmers with a coefficient value of 0.992 which proves that entrepreneurship is an intermediary variable to increase human resources in the border region, especially for adan rice farmers in Krayan district, Nunukan district.

Abstract
Chrysanthemum (Chrysanthemump) is a one of the most popular cutting flower commodities in Indonesia. The beauty of colors and variations in the shape of flowers and the low level of withering cause Chrysanthemum to be in great demand. The polyploid chrysanthemum has some superior properties but the growth rate and flowering time is slow due to colchicine. The study aimed to determine the influence of the concentration of the cytokinins in the growth and productivity of chrysanthemum polyploid genotypes. The experimental design as used Split Plot Design consists of 2 factors and 2 replications. The first factors were concentration of the cytokinin (Si, i are 1,…,4) as a main plot with different levels about 0, 1, 2,3, 4 ml L−1 of cytokinin solutions, respectively. The second factorswere the third generation of the polyploid chrysanthemum (G) genotype as a sub plot with 4 genotype, namely: g0 = KRA0, g1 = KRA1, g2 = KRA2, and g3 = KRA3. Based on the experiments and analysis results, it was found that the treatment of 3 ml L−1 of the cytokinin solution produced 16 shoots while the polyploid chrysanthemum genotype KRA2 gave the best response to the number of shoots at 12 WAP compared to other polyploid chrysanthemum genotypes.

Abstract
Queuing is an important component of a process in service. Queues are formed in a company or institution due to customers. Disorderly queues are a big problem for all concerned. Where, disorderly queues occur at University Prima Indonesia at the time of tuition payment so that the campus has to carry out a crowded queue process and students have to stand waiting for the next call resulting in less effective and efficient even waste of energy for students and employees. This research designed a system of tuition payment queues using the First In First Out (FIFO) algorithm which aims to reduce the time students are queuing at the checkout at the time of tuition payment so as not to wait too long so that the time of students and campus employees is not wasted too much and reduce the crowded queue time. The result of this study is an android-based tuition payment system, which is useful for reducing student build up when paying tuition. Thus it can be said that the calculation result of P0 queue has a result of 0.25%, and the number of customers 3 people, the average customer in the queue has a value of 2.25, the total customer time is 20 minutes, and the average customer time in the row is 15 minutes, the server busy time is 0.75, and the server’s empty time is 0.25%.
Circular economy and resilience: convergences and deviations in the case of agri-food supply chains

Published: November 2021

Abstract
Agri-food supply chains have a multitude of roles for the mankind. Among others, they encompass the primary, secondary and tertiary sectors of the economy; they are responsible for feeding the planet; they are associated with various environmental and social impacts. Therefore, their operation, efficiency and performance are crucial in many contexts. In this paper we investigate the transitions of agri-food supply chains towards two different goals: circular economy and resilience. Circular economy has been a focal priority in the EU and global agenda, which aims at redefining the patterns that have been associated with linear economy models in order to meet environmental, social, and economic challenges of our era. On the other hand, supply chain resilience is the capacity of supply chains to be prepared for unexpected risk events, act and recover promptly to probable disruptions, and return to their original position or move to a better ideal condition. In particular, we focus on the enablers and barriers for both goals and identify possible convergences and deviations. The former are expected to lead to win-win opportunities, whereas the latter will lead to trade-offs.

Published: November 2021

Abstract
One of the main parameters for the design of cigarettes is filter ventilation. As filter ventilation increases, the concentrations of Tar, Nicotine and CO (TNCO) emissions decrease. This work examines the correlation between filter ventilation and TNCO emissions, using the data of the cigarettes notified in the French market. The average values of filter ventilation, pressure drop with open and close vents and also of TNCO emissions remain quite constant during the three years examined (2018-2020). A mathematical model linking the value of filter ventilation with the values of TNCO emissions is developed. According to this model, the values of filter ventilation estimated from this model show a very good agreement with the measured values in the case of cigarettes with filter ventilation higher than 50%. Now such model could be established for lower ventilation values. These results show that the proposed model can be effectively used to correlate filter ventilation with TNCO emissions, in the case of ventilation values higher than 50%.

Authors: Avramidou M , Manika S 
Published: November 2021

Abstract
The concept of urban resilience, either as a response to the effects of climate change or as a need to address the emerging challenges of the pandemic crisis, plays an important role in the modern forefront of urban policies. This article focuses, in the light of climate change, on the prospects of the adoption of the principles of urban resilience in the design of urban outdoor spaces, initially creating a clear framework for their definition. In order to achieve this, the article proceeds to the evaluation of successful European and Greek examples of urban open spaces in which the assurance of urban resilience is achieved through the application of bioclimatic design. Emphasis is placed on the factors of sunlight, ventilation, the role of water and greenery, and the properties of surface coating materials in urban outdoor spaces. Then the study area is analyzed, with qualitative and quantitative assessment of the factors that affect the outdoor environment.

Published: November 2021

Abstract
Urban heat island (UHI) is a phenomenon that affects the urban microclimate. Land use, urban geometry, cover materials, vegetation, the water element and human activities are the most important factors that affect the UHI. This research focused on the study and analysis of the urban microclimate of three sections of a commercial street area that differ in their morphology. The first area includes a stream near the road, the second area includes the purely commercial part of the street and the third area includes the fringes of a hill in (Thessaloniki, “Toumpa”, Gr Lampraki Street). Using the Envimet V4 program, three simulations were performed for the selected study areas for the hottest day of the previous year, August 1, 2020. The values with the largest variations in all three areas were those of relative and specific humidity and finally air speed. The air temperature was higher in relation to the suburban area (UHI) and did not show significant differences in the three study areas. This leads us to the conclusion that the urban morphology, orientation and geographical location of the three study areas played the most important role in shaping the urban microclimate. Finally, is suggested one alternative scenario for optimizing the microclimate in the most burdened area of the three.

Published: November 2021

Abstract
Climate change is an ongoing fact with evident impacts on earth, humanity and our heritage. The management and protection of heritage from the effects of climate change should be taken into consideration, so as to act dynamically and immediately, since the effects of climate change are rapidly evident in all aspects of life. The objective of this research is to study the vulnerability of the ancient Greek Theatre of Dionysus, as it forms a monument with embedded heritage values exposed to the climate change. This case study is the tangible result of a particular cultural and historic research, bearing historic knowledge, cultural meanings via a recognizable architectural structure and it reflects the conjunction of culture with society and nature. Materiality and its pathology combined with the condition of the natural landscape and the altering pattern of cultural tourism can lead to the study of climate change imprint on this kind of heritage, which should be examined as a wholeness of culture and nature. The uniqueness in the Theatre’s identity and historic path deserves interpretation of the effects of climate change, so as to manage adaptation, proactive planning, mitigation and dissemination of the discovered results.

Published: November 2021

Abstract
The case of cultural resources, and in particular of archaeological sites, is one of the key elements of the anthropogenic environment that is affected by climate change and needs protection. At the same time, it is a field of analysis allowing the understanding of the interactions and interconnections of natural and socio-economic systems in time and in different spatial scales, thus providing useful information on the phenomenon of climate change and on how to respond and adapt to it [1]. However, the related scientific research, policies and actions are still limited, as only in the last decade [2] there has been an (albeit ever-increasing) interest in this field. The main objective of this paper is to codify protection policies and to identify a typology of actions for major archaeological sites with tourist interest in Greece, in order to identify a framework for spatial planning to meet the challenges of reducing the effects of climate change such as: the adoption of an integrated design approach to the protection of cultural heritage rather than a traditional conservation approach; linking the cultural heritage with the natural environment; Bridging existing gaps and redefining cultural heritage in dynamic and spatial terms for both climate change adaptation and also emergency preparedness and disaster risk reduction.
Investigation of climate change impacts on hydropower generation: the case of a run-of-river small hydropower plant in North Western Greece
Authors: Skoulikaris C , Kasimis K 
Published: November 2021

Abstract
Services and uses arising from surface water‘s availability, such as hydropower production, are bound to be affected by climate change. The object of the research is to evaluate climate change impacts on energy generation produced by run-of-river small hydropower plants with the use of future river discharges derived from two up-to-date Regional Climate Models. For doing so, the hydropower simulation model HEC-ResSim, calibrated and validated over real power data, was used to simulate the generated energy in the two future periods of 2031-2060 and 2071-2100. The future river discharges in the case study area are derived from the hydrological model E-HYPE that uses as forcing the climatic variables of the CSC-REMO2009-MPI-ESM-LR and KNMI-RACMO22E-EC-EARTH climate models under two Representative Concentration Pathways, namely RCP4.5 and RCP8.5. The research outputs demonstrate a decrease of the generated energy varying from 2.86% to 25.79% in comparison to the reference period of 1971-2000. However, in most of the simulated scenarios the decrease is less than 10.0%, while increased energy production is projected for one of the scenarios. Overall, it can be concluded that the case study run-of-river small hydropower plant will be marginally affected by climate change when the decrease of the relevant river discharges is up to 10-15%.
Evaluation of decoupling of GDP and CO2 emissions in EU-15
Authors: Bekaliyev A , Junissov A , Kakimov Y , Poulopoulos S G 
Published: November 2021

Abstract
Generally, economic growth is accompanied by an increase in energy consumption, which consequently leads to higher levels of greenhouse gas emissions. These, in turn, are the causes of global warming, which is one of the most acute environmental problems nowadays. Decoupling occurs when environmental pressure can be decreased without the negative effect of the economic growth of a country. This study is focused on the investigation of the decoupling of the economy and environmental pressure. The analysis was carried out for EU-15 countries for the period between 1990 and 2014. For the evaluation of decoupling the Tapio decoupling elasticity method was used. This method provides the extent of decoupling of the economy and environmental pressure for each country. The economy was measured in terms of gross domestic product (GDP), while the environmental pressure was represented by CO2 emissions from the public electricity and heat generation sector. The EU-15 countries were classified into three groups depending on the individual reduction targets following Kyoto Protocol. Group I had high values of reduction targets ranging from -28% to -12.5%, Group II had moderate values of reduction targets situated between -7.5% and 0%, and Group III had mild values of reduction targets from +4% to +27%. The results of this analysis show that there is strong fluctuation of the extent of decoupling between GDP and CO2 emissions for each country in the specified period. Therefore, there are no clear patterns of decoupling intensity that can be observed. However, it is important to notice that in almost every country the decoupling between GDP and CO2 emissions was either strong or weak. This study has shown that generally most of the countries achieved some extent of decoupling between the growth of the economy and the pressure on the environment. The countries that showed the decoupling of more than 80% of the specified period are Luxemburg, Ireland, and Italy. For most of the countries, the decoupling was deteriorated by the financial crisis of 2008. Another possible reason for the decrease in decoupling is the extensive use of renewable energy resources. While their application lowers the CO2 emissions, the high production and operation costs constrict the growth of the economy. Sweden, Finland, and Denmark had such situation.

Published: November 2021

Abstract
In the dawn of innovative digital tools for communication and information exchange the civil society has apparently taken a step forward into this new direction. This paper explores the process for enhancing E-participation in environmental planning and making relevant government decision-making democratically accountable. Environmental issues are dealt in the civil society context with reflexivity that incorporates lay and local knowledge. The case study emphasizes on the BLN e.V e-participation platform “Umwelt-Beteiligung-Berlin” and discusses the extent and impact of Environmental Associations involvement in sustainable environmental planning. BLN e.V was created as a hub for all Berlins registered Nature conservation/Environment protection associations as well as citizens’ initiatives on environmental projects. The platform was developed in cooperation with the nature conservation associations recognized in Brandenburg and Lower Saxony. BLN working group is supported by volunteers in the Federal Ecological Volunteers Service (ÖBFD). The paper analyses the case study impact and concludes by discussing how the concept can be proliferated on EU, national, regional and local level and the prospects of future research.
