Problems of energy security, diversification of energy sources, and improvement of technologies (including alternatives) for obtaining motor fuels have become a priority of science and practice today. Many scientists devote their scientific research to the problems of obtaining effective brands of alternative (reformulated) motor fuels. Our scientific school also deals with the problems of the rational use of traditional and alternative motor fuels.This article focused on advances in motor fuel synthesis using natural, associated, or biogas. Different raw materials are used for GTL technology: biomass, natural and associated petroleum gases. Modern approaches to feed gas purification, development of Gas-to-Liquid-technology based on Fischer–Tropsch synthesis, and liquid hydrocarbon mixture reforming are considered.Biological gas is produced in the process of decomposition of waste (manure, straw, grain, sawdust waste), sludge, and organic household waste by cellulosic anaerobic organisms with the participation of methane fermentation bacteria. When 1 tonne of organic matter decomposes, 250 to 500–600 cubic meters of biogas is produced. Experts of the Bioenergy Association of Ukraine estimate the volume of its production at 7.8 billion cubic meters per year. This is 25% of the total consumption of natural gas in Ukraine. This is a significant raw material potential for obtaining liquid hydrocarbons for components of motor fuels.We believe that the potential for gas-to-liquid synthetic motor fuels is associated with shale and coalfield gases (e.g. mine methane), methane hydrate, and biogas from biomass and household waste gases.

The research paper analyses the ongoing conflict between the residents of the Northern Netherlands and the central government regarding the compensation of damage caused by induced earthquakes and the gas-mining through the theoretical framework explaining relations between the periphery and the centre. The Groningen gas debate is an interesting case, as it shows the potential of change in the established power relationship between the periphery and the centre. the paper analyses the factors that led for this change and explains the change mechanism that is associated with the persuasive power of the local social movement. The paper contributes to the literature on environmental governance, energy transition, communication and political science.

ABSTRACT: Local homebuyers in the Groningen earthquake regionIr. Hieke T. van der KloetHanze University of Applied Sciences GroningenResearch Centre for Built Environment NoorderRuimteh.t.van.der.kloet@pl.hanze.nl0031-50-595-2015The earthquakes after the natural gas extraction in the Groningen region of the Netherlands have a significant impact on the housing market and sustainability of the communities in this region. Since the strongest earthquake around the community of Huizinge in August 2012, with an magnitude of 3.6 on the Richter scale, it became clear there is a relation between natural gas extraction and earthquakes due to soil subsidence. As a consequence houses in the region get damaged and after research it gets obvious housing prices decline and the region will become unattractive to potential buyers of houses, damaged or not. Therefore the Dutch Petroleum Company (NAM) since April 29th 2014 offers a compensation for the loss of the housing price before and after the earthquake of Huizinge to property owners who want to sell their home. They only get the compensation after a sales deal and only if they agree with the proposed compensation. Since the compensation for the decrease in house prices has been introduced, the number of participants of the regulation is lacking behind the actual sales of houses. Our study aims to contribute to the research on the consequences of earthquakes by natural gas mining on the real estate market in the northern part of the Netherlands, especially the Groningen region. First of all we want to declare why relatively a large part of the property owners (about 60% until 2015) don’t request for the compensation regulation. Our second question concerns the buyers of the (damaged) houses in the earthquake area. Why would they buy a home in a region full of risks? Who are these buyers? We use a mixed-method approach for data collection which leads to an analysis of a unique dataset on notarial deeds of house sales in nine municipalities in the Groningen earthquake region according to The Land Registry of the Netherlands during the period 2013 until the end of 2015 as well as discovering common patterns of interview results with residents and experts. First results show that the majority of the homebuyers originate from the local earthquake area in the Province of Groningen. Reasons why property sellers after the house sale don’t opt for the compensation regulation concerns the complexity of the regulation, the used valuation model and the expected long control time afterwards.From the first results we conclude that the Groningen earthquake region still has its attractiveness for local residents and buyers. Otherwise the regulation for compensation doesn’t reach enough property sellers in the nine municipalities of the Groningen earthquake region. Advise to the Dutch government should be to generously compensate the residents of the Groningen earthquake regions for the loss of value of their dwellings, damaged or not. This will help to improve the regional development and attractiveness of areas that are effected by earthquakes.

Er zijn veel instanties betrokken bij het oplossen van de problemen door de aardbevingen in Groningen. Dit systeem van aanpak is complex en zorgt voor veel belemmeringen. Dat vertellen professionals op verantwoordelijke functies in dit systeem. Zij ervaren ze hun werk als veeleisend en soms ‘gekmakend’. Voor dit onderzoek (in opdracht van de Nationaal Coördinator Groningen (NCG)) zijn 33 professionals geïnterviewd. Behalve bij NCG werken zij onder meer bij ministeries, provincie, gemeenten, Instituut Mijnbouwschade Groningen en Staatstoezicht op de Mijnen. De professionals kregen de vraag voorgelegd wat zij vinden van het functioneren van het systeem waarmee de aardbevingsproblematiek wordt aangepakt.

Immense beyond imagination, the untamed rainforests of western New Guinea represent a biodiversity hotspot, home to several unique species of flora and fauna. The territory’s astonishing beauty and diversity is underpinned by a stunning array of natural resources. The island is also home to many indigenous communities practicing hundreds of local languages and traditions and depending on their natural environment for maintaining their traditional livelihoods, identity and culture. The territory’s much-contested decolonization process in the 1950-60s led to widespread discontent among indigenous Papuans and gave rise to persistent dissent from Indonesian rule, routinely met with disproportionately violent action by Indonesian security forces. Adding to these longstanding colonial ills and grievances, indigenous Papuan communities also struggle to grapple with inequitable allocation of land and resources, extreme pollution and environmental degradation caused by the mining and palm oil sectors. In the meantime, climate-exacerbated weather events have become more frequent in the region creating new tensions by putting an additional strain on natural resources and thus leading to an increased level of insecurity and inequality. In particular, these challenges have a disproportionate and profound impact on indigenous Papuan women, whose native lands are deeply embedded in their cultural and ethnic identity, and who are dependent on access to land to carry out their prescribed roles. Displacement also puts women at further risk of violence. Adding to sexual violence and displacement experienced by indigenous Papuan women, the loss of traditional lands and resources has been identified as having a singularly negative impact on women as it impedes their empowerment and makes them vulnerable to continued violence. The Papuan experience thus serves as a timely illustration to exemplify how environmental factors, such as resource extraction and climate change, not only amplify vulnerabilities and exacerbate pre-existing inequalities stemming from colonial times, they also give rise to gendered consequences flowing from large-scale degradation and loss of the natural environment.

Een fles rode wijn per dag drinken is ongezond, maar een glas per dag reduceert mogelijk de kans op hartkwalen. Dit is een voorbeeld van ‘hormese’: het verschijnsel dat een agens dat in grote hoeveelheden schadelijk is, bij lage doses juist gezond is. Iets vergelijkbaars geldt voor zonlicht: lage doses worden geassocieerd met positieve gezondseffecten, hoge doses met verbranden en een hogere kans op huidkanker. Er zijn onderzoekers die zich op het omstreden standpunt stellen dat ook ioniserende straling hormetische eigenschappen heeft. In dit artikel gaan we nader in op de verschillende standpunten omtrent lage-dosiseffecten, de argumenten voor en tegen hormese en de consequenties van recente inzichten.

Valuation of heritage buildings is usually performed by architectural-historical experts, who use a typology of heritage values based on conservation philosophy. Increasingly, social and spirituality values are included in heritage assessment frameworks.What happens to valuation systems when external events influence the chances of survival of heritage buildings, such as earthquakes induced by gas extraction in the Netherlands? While the mining company uses a narrow economic perspective on value, the public fears for loss of character of their historic towns. New safety regulations constitute a new and even stronger threat to heritage buildings. Recently, a heritage assessment framework was published, to help with value assessments in the affected region. In this paper, we compare experts’ and laypersons’ values by analyzing the new assessment framework as well as public documents. We conclude that heritage value assessments should incorporate social values, including memories and symbolic meanings, to create a balanced valuation system.

Energy policies are vital tools used by countries to regulate economic and social development as well as guarantee national security. To address the problems of fragmented policy objectives, conflicting tools, and overlapping initiatives, the internal logic and evolutionary trends of energy policies must be explored using the policy content. This study uses 38,277 energy policies as a database and summarizes the four energy policy objectives: clean, low-carbon, safe, and efficient. Using the TextCNN model to classify and deconstruct policies, the LDA + Word2vec theme conceptualization and similarity calculations were compared with the EISMD evolution framework to determine the energy policy theme evolution path. Results indicate that the density of energy policies has increased. Policies have become more comprehensive, barriers between objectives have gradually been broken, and low-carbon objectives have been strengthened. The evolution types are more diversified, evolution paths are more complicated, and the evolution types are often related to technology, industry, and market maturity. Traditional energy themes evolve through inheritance and merger; emerging technology and industry themes evolve through innovation, inheritance, and splitting. Moreover, this study provides a replicable analytical framework for the study of policy evolution in other sectors and evidence for optimizing energy policy design

Background There currently is no field test available for measuring maximal exercise capacity in people with stroke. Objective To determine the feasibility, reproducibility and validity of the Shuttle Test (ST) to measure exercise capacity in people with stroke. Design Longitudinal study design. Setting Rehabilitation department, day care centres from a nursing home and private practices specialized in neuro rehabilitation. Subjects People with subacute or chronic stroke. Interventions A standardized protocol was used to determine feasibility, reproducibility and validity of the 10-meter Shuttle Test (10mST). Main measures Number of shuttles completed, 1stVentilatory Threshold (1stVT). Results The associations of the number of shuttles completed and cardiopulmonary capacity as measured with a portable gas analyser were r > 0.7, confirming good convergent validity in subacute and chronic people with stroke. Criterion validity, however, indicates it is not a valid test for measuring maximal cardiopulmonary capacity (VO2max). Only 60% of participants were able to reach the 1stVT. Higher cardiopulmonary capacity and a higher total score of the lower extremity Motricity Index contributed significantly to a higher number of shuttles walked (p = 0.001). Conclusions The Shuttle Test may be a safe and useful exercise test for people after stroke, but may not be appropriate for use with people who walk slower than 2 km/h or 0.56 m/s.
