Leachate is a liquid waste product of the processes in solid waste landfills with meteoric waters seeping. A number of substances are dissolved by washing with meteoric water and other substances resulting from the processes of fermentation of organic waste components. Leachate treatment is essential to reduce mainly the organic and nitrogen content in the leachate. The initial solution applied to the purge unit-Glina was a biologic reverse osmosis in two steps (osmosis layout). An aeration lagoon has been designed and proposed to be installed as pilot in Glina. The leachate provides the food for the bacteria and the aeration system provides the oxygen. The results are suggesting that this lagoon technology can be economic to install and simple to run.

In Turkey, the demand of table grapevine rootstocks is increasing day by day since the value of table grapevine rootstocks increase. On the other hand, production of table grapevine does not meet the demands of market since grapevine rootstock production efficiency is low. So, its production efficiency must be increased. Nowadays, hydroponics system is becoming a quite common and alternative method as compared to traditional farming systems of cultivation of soil, because hydroponics systems offer a wide range of advantages such as high capacity of production, high quality of products and also reduce the use of pesticides as compared to the traditional methods of cultivation. Grapevine variety namely, Yalova Cekirdeksizi has been taken in summer growing season and used its green cuttings as living material in this research work. The obtained cuttings were transplanted to different pots in three different time periods (15th of June, July and August in the year 2015). Grapevine rootstocks were placed to the pots having the dimension of 22 cm in width, 72 cm in length and 17 cm in depth. Each pot in the experiment possessed the same amount of fertilizer and the drip irrigation system has been applied. A microcontroller (PIC16F84) device has been used as an automated controller for supplying the water to the experimental trials. The irrigation system has been comprised with three main parts i.e., submersible pump, power suppliers (12 volt DC) and some other connected apparatus. In this experiment, a time based closed loop hydroponics system has been used aimed to test the performance of the automated hydroponics system for the growth of grapevine rootstocks. Consequently, the system took over the all irrigation procedures successfully throughout the entire growing season.

Green Power Sustainable Food and Euro-Atlantic Romania, integrated and globalized, based on eco-bio-economy, represents a new direction of development that should mark the transition to a new sustainable social market economy, a smarter, greener economy , in which our prosperity is due to innovation, better use of resources and the knowledge to be a key factor. They are also the principles underlying the EU Strategy 2020 and the European bioeconomical Strategy 2030, developed in Germany through which the European Union aims to accelerate progress towards a knowledge economy, but an environmentally friendly economy. Metabolic energy as specific form of nutritional energy by externalizing the productive potential of feed is running photosynthesis so a specific form of solar enrgie obviously fall in global concept of'' green power''.We believe that Sustainable Food Green Power as a new original concept launched in the Postdoctoral School, is based entirely on complex use of various forms of green energy (solar, wind, hydropower, geothermal energy, etc..), And how to meet specific food production based on eco-bio-social and rural economy (according to the strategies of social inclusion objective of the Lisbon 2030) is actually a confirmation of theoretical and practical aspects and analytical synthesis that the authors have found the-over the years the scientific organization (management) and recovery (marketing) and sometimes record high yields recorded continuously for agro-pedo­climatic conditions of ecozona Cezieni Olt County.

This study was carried on to determine the effect of different irrigation regime on winter wheat crop and water-use efficiency (WUE). For this purposes the experiment was conducted with 4 different irrigation treatment which was I1; Rainfed, I2; Full irrigation (irrigate when calculated soil water depletion is 60 mm) I3; Limited irrigation (2 irrigation maximum) one at tillering and another at grain filling, I4; No irrigation after establishment until heading, after which irrigation when soil water depletion is 60 mm below field capacity at Saraykoy Research Station in Murted Basin. The experimental design was completely randomized block design with four replications. Soil moisture was measured with neutron probe. At the end of the research study conducted during the wheat growth period for the years 2009-2010 and 2010-2011, in average wheat yield was found to be 3.35 t ha-1, 4.54 t ha-1, 4.22 t ha-1and 4.31 t ha-1respectively according to the plots (I1, I2, I3, I4). The highest yield was obtained from the full-irrigation plot while the lowest yield was obtained from the no-irrigation plot. No statistically significant difference was found between the plots subjected to the irrigation treatments while a difference of P < 0.05 was obtained between the no-irrigation and full-irrigation plots. Average harvest index values were found to be respectively 29%, 31%, 32%, 31% and 32% again according to the plots. A significant negative correlation was found between grain yield, total harvested biomass and the WUE. The results presented in this work suggest that the amount of soil water content affects grain yield and water use efficiency. It might be recommended that irrigation concentrated in the after heading period increase WUE in Central Anatolia Region of Turkey. Crop water stress index is a useful tool for detecting crop water stress.

The paper consists of the calculation of drinking water demand for water supply of the villages from Barlad hydrographic basin. We took into account a total of 137 parishes in 6 counties (Vaslui, Bacau, Galati, Iasi, Neamt, Vrancea), 3 municipalities (Vaslui, Barlad and Tecuci) and two cities (Husi and Negresti). The total number was 647 735 inhabitants. The calculation of drinking water demand was done taking into account the distribution of the number of inhabitant for each parish, municipality and town according to the population census conducted in 2013 and also by respecting the Romanian standard STAS-SR 1343/1-2006 regarding to the calculation of drinking water demand for urban and rural areas. This yields to the following flow of drinking water demand for the resident inhabitants in the territory of Barlad catchment: Qzimed = 94575.57m3/day, Qzimax = 135178.03 m3/day, Qorarmax = 13963.91 m3/day. The annual volume of drinking water demand is 34525.024 thousand m3. During the calculus no account was taken of the water required for fire blow out.

Irrigation management is one of the key factors for the sustainability of irrigated agriculture. There has been a good number of performance indicators developed for the assessment of irrigation schemes. DSI (State Hydraulic Works) datas for 5 years (2011-2014) were used to calculate indicators of irrigated agricultural output. The most important one among them is the four basic comparative performance indicators related output to unit land and water. These “external” indicators provide the basis for comparison of irrigated agriculture performance. Comparative indicators are the output per cropped area ($/ha), output per unit command ($/ha), output per unit irrigation supply ($/m3), and output per unit water consumed ($/m3). In this paper, obtained the data that regarding irrigated cropped area, production, which are the output of the irrigated area in terms of gross or net value of production measured at local prices, command area, diverted irrigation supply, volume of water consumed by ET. This data were used to calculate comparative indicators. This study, in three climatic zones (Continental, Mediterranean and Black Sea) fourteen irrigation schemes, more than 20.000 ha of command area for each scheme, were assessed. Irrigation schemes were classified with regard to crop pattern. As a result of the study, based on the 2011-2014 years output per unit command area, output per cropped irrigated area, output per unit irrigation supply, output per unit water consumed were determined as 1040-7669 US$/ha, 2387-10129 US$/ha, 0.13-1.38 US$/m3, and 0.60-2.29 US$/m3, respectively. Calculated comparative indicators compared with each irrigation scheme's crop pattern and climatic zone. In addition, results compared with irrigation schemes in similar climatic zone with similar crop pattern. In conclusion, it was determined that crop pattern is the most effective factor to success of irrigation schemes.

Lemna sp. have an important role indifferent aspect of aquatic ecosystems serving as a food source, by providing shelter to fish and aquatic invertebrates, changing water quality by regulating oxygen balance, nutrient cycles, and accumulating heavy metals.The aim of present study was to investigate a new found species of Lemna in Bulgarian water reservoirs regarding their protein content and bioaccumulation of heavy metals. Two water bodies located on the territory of South East Bulgaria –Tvardica Dam Lake with growing L. minuta and Nikolaevo fishpond with growing L. valdiviana were studied. Crude protein, lipid, ash contentin two species of Lemna were analysed. The heavy metal in water andaquatic plants was determined on an atomic absorption spectrometer (AAS) "A Analyst 800" - Perkin Elmer. The highest quantity of protein was measured in L. minuta (26.42%), which was 8.71% more compared to L. valdiviana (24.12). The concentrations of metals in the L. minuta and L. valdiviana followed a downward trend: Mn>Fe>Zn>Cu>Ni>Cr>Pb>Cd. The series of bioaccumulation is in descending order: Mn>Fe>Cu>Zn>Cr> Cd>Pb>Ni for L. minuta, and Mn>Fe>Zn>Cu>Cd>Pb>Cr>Ni for L. valdiviana.

Rose oil processing wastes (ROPW) resulted from water distillation process from petals of R. damascena Mill, which is a by-product of rose oil producing industry leads to environmental problems such as odor and visual pollution. Since these wastes are rich in organic matter, it could be considered as a briquetting material to produce bioenergy. A hydraulic press was used for briquetting process in this study. Two different hexagonal dies with the height of 150 mm were used. No binding material was mixed with ROPW. The resultant briquettes were full hexagonal briquettes with the height of 100 mm and the outer diameter of 60 mm and hollow-core hexagonal briquettes with the height of 100 mm and the outer diameter of 80 mm with 20 mm inner diameter of central hole were produced. All briquettes were stored under ambient conditions for 7 days before testing. Shattering resistance, abrasive resistance, air humidity resistance, water intake resistance tests, thermo-gravimetric analysis, and flue gas emissions (CO2, CO, SO2, and NOX) were performed. The results were discussed in the paper.

The paper presents the analysis of collapse and damage state to some special buildings during recent severe surface earthquakes, The presented irregular reinforced concrete buildings (with irregular distributions of mass, stiffness, strength, geometrical configurations), especially the setback structures and tall structures, have exhibited a poor seismic performance. Through graphical representations of response spectra obtained from records, it is revealed that most of the damage occurred to buildings due to exceeding the code requirements, the level of accelerations and to the spectral composition, unusual to the surface earthquakes, which justify the shown interest. Comparative analysis of numerical data is shown in order to put into evidence the effects of surface earthquakes on buildings. It must be accepted that an important role in the overall behaviour of the presented buildings had the higher modes of vibration and shaking time, beyond the technical aspects. What is noticeable, also, are the long periods of motions, although the earthquakes are of surface. The more accelerograms recorded are, we find that the possible values may be higher than those from design codes and sometimes the codes provisions are taken from other design rules (with other local features).
