Heavy metal pollution is a major environmental problem that can affect productivity, quality of the finished product andthe quality of human health. Since the 1990s, heavy metal pollution proves to be a problem in some major wine regions.In recent decades several anthropogenic activities have caused a remarkable release of trace metals into agriculturalsoils. Some trace elements (copper, zinc and manganese) are essential to plant growth and are called micronutrients.These elements are also heavy metals, and are toxic to plants at high concentrations.The objective of the present research is to evaluate Mn, Zn, Al, Cr and Cu (mg/100g) contents in the canes ofgrapevines of two local varieties, Royal Feteasca and Merlot grown in two private vineyards located near Craiova,namely Breasta and Simnic, an also their concentrations in soils. Canes and soil samples were collected in April andMay 2014. For samples analyses were used the following equipments: mass spectrometer with inductively coupledplasma, flame atomic absorption spectrometer - Avanta, Milestone microwave digestion system.Determined values for Royal Feteasca variety were higher for vines located in Breasta vineyard, except aluminumcontent which was higher in Simnic vineyard. For Merlot variety, the values measured were considerably higher forvines located in Simnic vineyard. Following the interpretation of the results obtained, it can be concluded that theresults of all metal concentrations in analyzed soils are higher in Simnic vineyard than in Breasta.

Romania has a long-standing tradition of mining, particularly within the Apuseni mountains area. Unfortunately, thereare various negative consequences which occur as a direct and indirect result of this process, such as acid minedrainage and heavy metal pollution of air, soils, surface and underground waters. This paper proposes an integrativeand interdisciplinary strategy for the depollution of acid mine drainage and heavy metal contaminated areas in theApuseni Mountains, Romania. We aim to view the reported problems within the designated area, which occur as aresult of ore exploitation, from various perspectives (environmental science and engineering, medicine, veterinarymedicine). Secondly we aim to provide a plan of action for depollution. Specifically we will focus on: the treatment oftailing ponds and surface waters, soil remediation, greening of heaps of debris, mine closure, stabilization andrehabilitation. We wish to focus on efficient, technologically easy to implement solutions, which preferably use natural,indigenous materials.

The paper refers to the monitoring of vertical displacements of rockfill (riprap) dams, displacements caused by theprocess of material compaction of dams. In order to monitor the vertical displacement, on the weir crest and bermssituated on the downstream-side were placed tracking markers. To determine the vertical displacements was used aDNA 03 level and DNA levelling invar staff. Measurements processing was done rigorously through the method ofconditional measurements and indirect measurements. The case study was conducted on the Belis Fantanele dam usingthe measurement periods of May to October 2013, respectively from March to November 2014. The maximum recordedvalue of compaction is 312 mm on the RN10 landmark located on the dam weir crest.

This article aims to emphasize the deformation state of a masonry wall, for four situations of masonry reinforcementwith polymeric grids. Polymeric grids are referred as seismic reinforcement solutions in the following masonry codes:Eurocode 8, and Romanian codes P100 and CR6. Polymeric grids can be used for confinement and reinforcement ofmasonry with bricks and mortar due to the properties of grids and mortar, and due to the cooperation betweenreinforcement and mortar that is anchorage.The masonry is an elasto-plastic material, to which characteristic curve σ-ε strain-deformation has a characteristicaspect. Deformation energy is represented by the surface determined between the σ-ε curve and the axis ε.The total specific deformation ε corresponding to a compression stress σ can be decomposed in two parts, one elasticεe, which is cancelled after the removal of external action, and the other plastic, remanent, εp.The case study present a comparative dynamic analysis of deformations state in structural masonry panels (softdiaphragms) in the following situations: plain, reinforce , confined and reinforced+confined masonry with polymer grids.

Determination and classification of plant patterns with satellite images is most suitable method for preparation ofsource inventory. The use of high resolution satellite imagery is quite widespread for separation of land use types. Pixelbased classification methods are widely used to classify images. The choice of classification methods in satellite imagesdirectly affects the success of the research. In recent years, the use of object-based classification method to determinethe plant pattern as parcels is being investigated. In this study, we present an example to determine the crop pattern asparcels using pixel and object based classification methods.The study was conducted in Isparta-Turkey. Quickbird-2 satellite image, ERDAS and e-Cognition Developer Trial 8.8software were used. Maximum likelihood and Isodata algorithms of Pixel-based classification methods and,multiresolution segmentation operator of object-based classification methods were used to classify satellite imagery.Object-based classification method was determined to be more successful than pixel-based classification method, basedour analyses.

The work hereby describes the setting up of database and its role within a GIS project. As already known, monitoringand management activities for a certain territory imply a significant amount of data as well as related processing andanalysis means. In such context, it is particularly important for both farming landowners and agricultural managementdecision-makers to determine the quality of soils and especially those affected by erosion decay processes. Availabilityof a descriptive database is critical for a GIS to work well. An attribute value (descriptive) database is connected to thespatial database to enable query. It is well known that the cultures structure and culture anti-erosion systems are two ofthe main factors on which agricultural management approach for slope land plots depends. The study hereby presentsthe many advantages of a GIS system for territorial management, and particularly for potentially erosive land. It isimportant to set up a database as complete as possible, that users can easily manage in order to be able to take the bestdecisions regarding “eco-friendly agricultural policy”.

Hippophae rhamnoides is a shrub whose fruit is of special importance for the essential elements that it contains:sugars, organic acids, proteins, oils, beta - carotene, trace elements, vitamins, fatty acids, amino acids, etc. For thisreason, this fruit is used for direct food but, most often, in pharmaceutical industry. Although it is not a waterpretentious fruit in the climatic conditions of Central Moldavian Plateau where extremely drought periods randomlyalternates with water excess periods, overcoming them in principle, we can’t achieve high yields, without interferingwith irrigation works. In this context, the paper presents conceptual aspects and the technical implementation of a dripirrigation system on a slope terrain, of 20 hectares, located near Iasi. The irrigation system has, as a source, thephreatic water taking from an open basin, dug at the heal base, in which the water infiltrates through the borders. Fromthis pond, the water goes to a pit, from where, using a water motor pump, the water goes to a superior attitude where itis placed another open pond, having its bad and margins covered up with a impermeable membrane. The second pondhave two functions: storing up and warming the water. The water transmission and distribution system consist of 60irrigation pipes, 9 transmission pipes and 1 adduction pipe made of 4 sections with diameters that vary between 32 and225 mm. The total number of drippers is 33000, they are the type of drippers with counterbalance pressure so that auniform distribution of water to all Hippophae rhamnoides rows should be ensure (15). The pressure uniformity to theupstream end of the irrigation pipes was accomplished by a rigorous hydraulic design which it is presented in thepaper. The described system was designed by the authors and, in 2014, it was operational.

Predicting seismic response of structures to future earthquakes contains a large dose of uncertainty. This is primarilydue to inability to know exactly the characteristics of future earthquakes, and in the second simplifying assumptionsused to calculate the structural response. One of these simplifications is that current design methods used elasticcalculation, while the response of several structures under the action of an earthquake is inelastic.

Located in a temperate – continental area the Romania’s mainland is influenced in the last period by the worldwideclimate changes: extreme weather conditions (high temperatures and prolonged dryness, rainfall accompanied bystorm) what have as effects: increasing the risk of desertification, floods, forest fires, erosion, landslides, flash floods,snow squall etc. As precipitation effects have resulted leakage liquid and solid, in particular on slopes without forests,which led to the submission of material eroded in river beds. Concentrating leaks have resulted in an increase in flowsof the volume and speed both water on slopes as well as the network of sinks and intensify torrential erosion processes.Floods have been accompanied by intense processes of erosion of the banks causing subsidences or land slides. Theother vessel types were excessive transport have clogged hydrological collecting network and as a result, havediminished the ability of transit of liquid flows, increasing frequency and flood, with negative implications for waterquality and social and economic activity. The paper, address an integrated approaches cause-effect by analysing riverPutna’s basin following aspects: analysis of risks and their main causes of, any effects on the ecosystems, vulnerabilityof water resources, measures to reduce their impact on water resources.
