Resveratrol concentration in ‘Vranac‘ wines

Red wine is the main source of resveratrol. It occurs in both, isomeric (trans- and cis-) and in its glucosides forms. The grapevine variety, climate, conditions and duration of wine storage, and phytosanitary conditions of grape are some of the factors  that influence content of resveratrol. This study analyzed trans- and cis-resveratrol isomers concentrations and trans-resveratrol-3-O-glucoside and cis-resveratrol-3-O-glucoside concentrations among three clone candidates and population of autochthonous Montenegrin grapevine variety ‘Vranac’. Data from period of three years were collected and analyzed with UPLC-MS/MS. Results showed no statistically significant difference (p = 0.169) in concentration of resveratrol among three clone candidates and population of grapevine variety ‘Vranac’

Origin and characterization of Montenegrin grapevine varieties

Viticultural tradition in Montenegro dates back before the Roman period. Viticulture and winemaking of Montenegro is still mainly based on autochthonous grapevine varieties ('Vranac', 'Kratošija', 'Krstač' and 'Žižak'). Relevant historical data concerning the origin of Montenegrin grapevine varieties, as well as Montenegrin germplasm characterization reviews are reported in this paper. The available literature data indicate a long tradition and an important breeding history of grapevine evaluation in Montenegro, especially concerning 'Vranac' and 'Kratošija'. Through international projects, by ampelographic analysis and DNA profiles, the originality of 'Vranac', 'Žižak' and 'Krstač' varieties was confirmed, while it was found that 'Kratošija' has the same genetic profile as 'Primitivo', 'Zinfandel' and 'Crljenak Kaštelanski'. According to the literature and to the exploration in vine growing regions, it can be concluded that Montenegro has a very rich grapevine germplasm, yet not investigated enough. Further works on Montenegrin germplasm will contribute to the better evaluation of the grapevine genetic resources of Montenegro, and, therefore, to the enrichment of grapevine diversity in Europe

Guiding principles for identification, evaluation and conservation of Vitis vinifera L. subsp. sylvestris

Conservation of grapevine genetic resources is an important and long lasting task. Here, partners of the InWiGrape Activity of the European Cooperative Programme for Plant Genetic Resources have proposed a set of descriptors that will assist in identification, conservation and study of genetic resources of Vitis vinifera L. subsp. sylvestris. A distribution map of Vitis vinifera L. subsp. sylvestris populations in Europe was produced, with on-line access through the European Vitis Database. The several different aspects of conservation of Vitis vinifera L. subsp. sylvestris including bibliographical references, identification in the wild, in situ and ex situ conservation have been discussed. The descriptors and the map will assist different stakeholders, working on biodiversity and ecosystems in more effective conservation of wild grapevine genetic resources

Future research priorities for climate friendly transport: agenda creation, consultation and results analysis

Research funding and innovation processes are key instruments to reduce greenhouse gas (GHG) emissions from transport. On the basis of scientific breakthroughs in recent years, the explosion in knowledge on transport sector is set to deliver a continuous stream of new applications. REACT is one of the FP7 projects that contributes to the development of a European-wide strategy on climate-friendly transport research funding based on a review of research themes’ importance. A Strategic Research Agenda (SRA) was set up, in order to define research priorities, develop future roadmaps, and suggest targets that can be actually achieved in the field of climate friendly transport. The SRA future vision is inspired by the EU strategic objectives towards 2020, e.g. shares the same targets for carbon reduction. The SRA has been built taking into account the current EU research programs on transport and mobility, analyzing the research agendas of selected European Technologies Platforms, and considering the points of view of different key stakeholders (market players, academics, policy makers, publics) through a consultation process. The consultation process has been articulated into three phases, characterized by different consultation procedures: 1. Expert validation of structure and initial; 2. Expert consultation, involving high profile experts and key–players in climate friendly transport; 3. Open consultation, a less detailed consultation but open to the wider public. REACT SRA considers all research areas in transportation that tackle the GHG emission problem, considering not only research on technology related aspects but also on policy, economy and social issues. The methodology for data analysis synthesizes results; it also considers and evaluates the level of certainty bound to responses received. A set of evaluations provides a general picture of the research priorities to be considered. Different ranks have been allocated according to weighting criteria that have been defined in numerous consultations with the experts. The identification of the most promising research areas is anticipated to give an indication to the European Commission of the research topics recommended for strategic financial support in the next decades

Pickup and delivery problem with transshipment for inland waterway transport

Inland waterway transport is becoming attractive due to its minimum environmental impact in comparison with other transportation modes. Fixed timetables and routes are adopted by most barge operators, avoiding the full utilization of the available resources. Therefore a flexible model is adopted to reduce the transportation cost and environmental impacts. This paper regards the route optimization of barges as a pickup and delivery problem (PDP). A Mixed Integer Programming (MIP) model is proposed to formulate the PDP with transshipment of barges, and an Adaptive Large Neighborhood Search (ALNS) is developed to solve the problem efficiently. The approach is evaluated based on a case study in the Rhine Alpine corridor and it is shown that ALNS is able to find good solutions in reasonable computation times. The results show that the cost is lower when there is more flexibility. Moreover, the cost comparison shows that transshipment terminals can reduce the cost for barge companies.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport Engineering and Logistic
