Abstract

The viticulture, a traditional branch of the national economy, is closely related to climatic conditions because the Republic of Moldova territory represents the northern border of its territorial location. Therefore the knowledge of regional particularities of grapevine productivity formation in dependence of current agro-climatic conditions is of particular interest. Along with accelerated climate change in last decades over the Republic of Moldova territory, we find that are essential changes concerning agro-meteorological conditions, at the same time comprehensive researches that would reflect the actual impact of climate change on grapevine are limited. There are known researches, but in the context of changes that occur at regional level it is necessary to supplement permanently the database in order to elaborate an appropriate estimation of current climate conditions. The above reported facts show the importance of parameters influencing the grapevine productivity time and space study in Republic of Moldova.

Abstract

Stroke remain the third cause of death and a major cause of disability worldwide. Our modern time enemy, atherosclerosis, with his many faces, is strongly related with stroke and its major subtypes. Ischemic stroke account up to 80 % of all stroke. As a subtype of ischemic stroke, lacunar infarcts remain an important concern. Aim of this study is to correlate carotid disease findings with lacunar stroke. We studied a group of 129 patients with carotid disease, and we established a possible relationship with lacunar stroke. Ultrasonography findings were correlated with the presence of lacunar stroke, confirmed by CT scan. Our study demonstrate that carotid plaques number could be a good predictor for lacunar stroke risk. External carotid plaques number is strongly correlate with lacunar stroke presence.

Abstract

In the present conditions when the demographic pressure upon the environment is higher than ever, the humanity faces the challenge of sustainability. Namely the sustainability of human activities is important and nothing can assure it better than sustainable energy supplies. The European Union is the leading global power in terms of adjusting its policies to increase innovation to assure a sustainable growth of its energy sector as a key to an advanced economic system. The present research focuses on the impact of European Union policies on the sustainable development of its energy sector by analyzing quantitatively and qualitatively various indicators intended to offer a throughout insight. The results obtained focus on the identification of the main innovation paradigms; the description of the main modern environmental challenges, especially in the energy domain; the determination of the relation between innovation and energy sustainability, and its analysis at the level of European Union.

Abstract

In this study we aim to highlight the risk of excess rainfall over the Republic of Moldova territory, analyzing the magnitude and frequency of maximum diurnal, seasonal and annual rainfall. The research is based on data from three meteorological stations (Briceni, Chisinau and Cahul) for the period 1950-2015. The maximum rainfall analysis from the three stations in the republic indicates a decrease of maximum annual averages from north toward south. Regarding the frequency of rainfall excess that reach and exceed the threshold of 50 mm - stands south of the country, being influenced by Mediterranean Cyclones. In annual aspect, for all analyzed stations, the highest frequency rank the classes reaching values of 500-600 mm, each station having its peculiarities.
