Oak wood has been highly praised since the Middle Ages for its strength and durability. This is one of the densest naturally occurring materials; it has good folding qualities despite its natural durability and has a high tannin content which makes it resistant to insects and pests. It is durable, impregnates easily, resists moisture absorption and thanks to its aesthetics and resistance, it is recommended as an excellent feedstock for the furniture industry and beyond, it is often used to manufacture floors, stairs, exterior and interior joinery, interior architectural elements, natural or stained plywood, boards, tiles, ornaments turners, profiles, barrels and it should be continuously promoted because it is a renewable and sustainable raw material. The oak stands have a significant position in the Romanian forests (18% of the country’s total forest area) and in the European ones; they are perhaps more appreciated now than in the past, not only for the particular structural qualities of the wood, but also because they contribute to the biological wealth of the forest ecosystems and for how they participate to the conservation of biodiversity creating an environment that helps to fulfil the social demands. Due to the present-day high market demand, the recent wood industry development and the multiple available transport options, oak wood is imported and exported at a high rate. It would be desirable to promote only those oak raw materials which originate from certified forest areas which are sustainably managed, where forest ecosystem services as well as certified wood chains of custody are promoted. That is why we need to identify, study and monitor the areas which are suitable for obtaining valuable forest stands with Quercus robur (pedunculate oak), Quercus petraea (sessile oak) or Quercus frainetto (Italian oak), and to ensure their growth by applying a sustainable forest management.

The purpose of this paper is to identify the perception of consumer on organic products in Romania market in November 2016. The methodology used was a simple survey which was done on 201 respondents from Galati, Romania, who answered to different questions in order to identify their perception and needs on organic products. The questions are closed questions with multiple options of answers. As a conclusion, Romanian consumers seem to be interested in consuming organic products because of their health benefits and taste, versus conventional products. First option in preference of organic products is fruits and vegetables followed by meat products. The survey showed us that organic products are easy recognized on the market after their specific labelling.

In the last years, zeolites have been researched for a variety of agricultural and environmental applications because possess unique properties: cation-exchange, adsorption, and molecular sieving. Zeolite can be used as soil conditioners, amendments, remediation agents in contaminated soils with heavy metals et all. Because commercially zeolites are expensive the researches have as objectives synthesis of new materials from different materials. These materials are raw or wastes, for example power plant ash, and can to be used effectively in soil applications if understand effects of these in soils or soil-like systems.The aim of this study is synthesis and characterization of zeolitic materials synthesized from power plant ash. Two different zeolite materials, rich in zeolite phases, K–cabazite were obtained from power plant ash, using 3 M KOH solutions at atmospheric pressure, temperature below 90°C and contact time of 4 and 8 hours.New materials were analyzed for their composition and properties. The synthesized products provide a significant increase of CEC (cation exchange capacity) and the high ability to adsorb heavy metal ions (over 39 mg gí1). Because synthesized materials have high cation -exchange capacities that can be used as cation-exchange in a soil. The high cation-exchange capacities determined several researches for using of materials for lead and copper removal from soil.

The gold mining activity performed in the past in Romania has led to the pollution of the environment, the degradation of large areas of land and currently represents a significant risk to human health. As a result of the gold mining activities performed in Almasu Mare area, there were large sterile dumps and gold mine galleries that continue to give their mark on the quality of the environment and human health through the amount of heavy metals in the soil and the sterile material improperly deposited, the water that comes out of the underground to the contaminated surface and which flows into the rivers in an uncontrolled way. This paper brings details of cadmium soil pollution in the studied area. The results obtained in the analysis of cadmium concentrations through the AAS spectrometry show that the analysed soil exceeds the admissible limits provided by the legislation in force, and the sterile material collected from the sterile dumps reflects values of the Cd concentration in the interval 10.7 – 22.6 mg/kg. Due to the high concentrations present in the soil and sterile material analysed, soil remediation interventions are required in the area.

The experiment was conducted over three years: 2009, 2010 and 2011, in five locations: Fundulea, Calaraúi county; Valu lui Traian, Constanta county; Sarichioi, Tulcea county; Cazasu, Braila county and Caracal, Olt county. These locations were selected as being representative for corn cropping area from South Romania. Eight corn hybrids (F475M, Olt, Paltin, F376 from Fundulea Institute and PR35F38, PR37Y12 , PR36V74, PR37F73 from Pioneer) were tested using two levels of water regime: irrigated with 800 3/ha and non-irrigated. The study showed that the 2009 was less favorable for corn crop in all testing areas, comparing with 2010 and 2011 which were favorable for corn crop. In the case of non-irrigated corn trials the yield was influenced by the climatic conditions of the year, while in the case of irrigated corn trials, the yield was much higher and stable. The hybrid PR36V74 had the highest yield in all irrigated and non irrigated testing locations. Average yield of the hybrids over three years varied between 93.8 q/ha (F475M) and 130,3 q/ha (PR36V74) in non-irrigated conditions, while in irrigated conditions average yield increased significantly by applying of 800 m3/ha varying between 101.2 q/ha (F475M) and 155,9 q/ha (PR36V74).

Sulphur is the fourth major essential nutrient element, after nitrogen, phosphorus and potassium, involved in biogeochemical cycles in nature. Sulphur is essential in all organisms because it is an integral part of major metabolic compounds, such as amino acids (methionine and cysteine), and it is an active component of numerous co-factors and prosthetic groups (Fe–S clusters, sulpholipids, glucosinolates, vitamins, etc), which are involved in metabolic processes of organisms. Medical research appears to confirm the validity of the use of sulphurous spring waters as therapeutical and preventive remedies for a large variety of diseases. In order to evaluate the quality of sulphurous water, samples have been taken of the Sulphurous Springs in Jibou. The objectives of this study were to determine physical and chemical properties (pH, electrical conductivity, salinity, redox potential) of some sulphurous water samples of Jibou area, and also to determine the microbiota involved in S biogeochemical cycle. The physical analysis showed that the sulphurous water of Jibou falls within the very weakly acidic reaction class, and the salinity was 0.2% in all samples. The aerobic heterotrophic bacteria show a maximum value in the sample 4 (2630x103 bacteria/ml). The microbial sulphurous community was detected in all water samples. This information should improve our understanding on adaptation mechanisms of bacteria involved in the sulphur cycle in correlation with physical-chemical parameters.

This research was conducted in hydraulic laboratory of Irrigation Department, Suleyman Demirel University, Isparta, Turkey. Different water temperatures (20, 30, 40 and 50°C) and operating pressure (80-200 kPa) were applied to determine emitter discharge equations (q= kHx), standard temperature discharge index (TDI, standard temperature is 20°C), coefficient of manufacturing variation (CV) and uniformity parameters such as Christiansen uniformity (Cu) and emission uniformity (CUE). On-line pressure compensating emitter with 2 Lh-1 discharges at system pressure of 100 kPa according to the manufacturer recommended, was used. Emitters were placed at 20 cm interval on the laterals with 16 mm diameter. Discharge equations related to temperatures were obtained as q=2.01H0.00, q=1.96H0.00, q=1.61H0.04 and q=1.54H0.05 respectively. Increased water temperature decreased the emitter discharge. The rate of emitter discharge decreased average 2.5% by increasing of water temperature from 20 to 50°C. TDI values decreased with increasing of water temperature (p<0.001). CV, Cu and CUE values of the emitters under different water temperatures ranged between 0.027-0.033, 97.3-98.5% and 89.2-96.7%, respectively.

The real estate development, the increase in the number of constructions made in the past years brings a complex problem, that of urban agglomeration, and implicitly all other problems deriving from it, environmental, social and economic issues. At the base of real estate development and the default of urban development is the system of cadastre and land book. By the very object of activity „the immovable” the cadastre and the urbanism activity are closely related. The aim of this study, is to find the method that brings together cadastre and urbanism information, to make the best decisions by the authorities responsible for these activities but also by citizens who want to achieve certain investment.

Drought refers to a temporary decrease in water availability, for example, when it doesn’t rain over a long period of time. On the other hand, water scarcity occurs when the demand for water exceeds the available sustainable resources. Most European countries are affected by the consequences of water scarcity, droughts and land degradation caused by water resources over-exploitation and exacerbated by climate change. The satellite systems present a wide range of new capabilities that can be used to assess and monitor the actual conditions of agro­ecosystems since information can be obtained on remote, wide area, non-destructive and/or real-time bases. Remote sensing data with low spatial resolution and high temporal resolution provide a useful tool for the monitoring of the vegetation activity from global to regional and local scale. The agricultural vegetation condition monitoring is currently possible, ranging from medium spatial resolution satellite derived - products, with daily revisit (NOAA­AVHRR, SPOT-VEGETATION, etc.) to high and very-high spatial resolution, offered by environmental satellites (LANDSAT, SPOT, FORMOSAT, IKONOS, QuickScat etc.) with longer revisit period. The most important parameters are: vegetation indices, maximum greenness during the growing season, total greenness during the growing season, fraction of photosynthetically active radiation and leaf area index.The study is focused on vegetation state assessment based on satellite derived products for drought monitoring (drought duration and intensity). This paper is based on the analysis of several vegetation indexes (NDVI, NDWI, etc) and biophysical parameters (LAI, fAPAR, land surface temperature, etc).The study area is focused on agricultural region situated in the western part of Romania, in the Romanian downstream of Mures River.

The paper aimed to determine the rate of change in swelling behaviour and liquid limit of clayey soils when exposed to natural seawater with respect to distilled water. The four clayey soil samples were gathered with different mineralogy and plasticity characteristics and tested to determine liquid limit and swelling characteristics in the presence of distilled water, tap water and seawater. The seawater effect is most noticed on the swelling behavior for montmorillonitic soils which have high plasticity.
