This paper gives examples of how long-term experiments can be used t o improve our understanding of sustainable farming systems. Rothamsted conducts more than 20 long-term (>20 years) experiments in south-eastern England; several were started in the middle of the last century. Some have continued with minor changes, others have been modified considerably t o ensure their continuation and relevance. Examples are given of the effect on soils and crop yields of organic matter, the availability of P, and acidification. The use of archived material in addressing problems not even considered when the experiments began is also discussed. Long-term experiments are essential in determining the factors affecting soil fertility and sustainable production. In many cases, effects may only be observed or interactions become apparent over an extended time. Full use should be made of existing experiments and data; in particular, those on different soil types and under different climatic conditions should be compared so that the information is valuable to farmers, advisers, legislators, and other scientists in both the local and wider community.

Summary This article elaborates on the issue of recognition and enforcement of foreign arbitral awards in the Russian Federation. It is common knowledge that foreign companies seeking R&E in Russia suffered damage because of the broad interpretation of Russian public policy in the past decades. However, it is uncertain how the present judicial development appears like and where it will lead in the future. The article specifically considers two basic ideas on the issue at hand: one is slightly critical (Karabelnikov) while the second is rather optimistic in regard with the recent development (Zykov). The main goal is to introduce the issue to the respective readers and to try to inflame a discussion.

The article outlines some human factors affecting the operation and safety of passenger air transport given the massive increase in the use of the VLA. Decrease of the impact of the CO2 world emissions is one of the key goals for the new aircraft design. The main wave is going to reduce the burned fuel. Therefore, the eco-efficiency engines combined with reasonable economic operation of the aircraft are very important from an aviation perspective. The prediction for the year 2030 says that about 90% of people, which will use long-haul flights to fly between big cities. So, the A380 was designed exactly for this time period, with a focus on the right capacity, right operating cost and right fuel burn per seat. There is no aircraft today with better fuel burn combined with eco-efficiency per seat, than the A380. The very large aircrafts (VLAs) are the future of the commercial passenger aviation. Operating cost versus safety or CO2 emissions versus increasing automation inside the new generation aircraft. Almost 80% of the world aircraft accidents are caused by human error based on wrong action, reaction or final decision of pilots, the catastrophic failures of aircraft systems, or air traffic control errors are not so frequent. So, we are at the beginning of a new age in passenger aviation and the role of the human factor is more important than ever.

Car ownership is one of the key factors affecting travel behaviour and thus also essential in terms of sustainable mobility. This study examines car ownership and how people’s willingness to own a car may change in the future, when considering the effects of public transport, Mobility as a Service (MaaS) and automated vehicles (AVs). Results of two citizen surveys conducted with representative samples (NAV-survey = 2036; NMaaS-survey = 1176) of Finns aged 18–64 are presented. The results show that 39% of respondents would not want or need to own a car if public transport connections were good enough, 58% if the described mobility service was available and 65% if all vehicles in traffic were automated. Hence, car ownership can decrease as a result of the implementation of AVs and MaaS, and higher public transport quality of service. Current mobility behaviour has a strong correlation to car ownership, as respondents who use public transport frequently feel less of a will or need to own a car than others. Generally, women and younger people feel less of a will or need to own a car, but factors such as educational level and residential location seem to have a relatively low effect.
