Bucharest is Romania’s capital,and in the north of this town from Romania it is a place located in Baneasa and on this surface it is intended to be built a construction having offices and administrative offices destination. Ensable wich make the object of study consists of two buildings and I decide that the cooling beams are a very good solution for air conditioning because they perform two functions : heating and cooling. These cooling beams are two types : active beam and passive beam.Both of them are very useful,but the difference between them is this one : For passive chilled beams, the heat transfer is done by radiation and convection, while in case of active chilled beams, heat transfer is enhanced because of recirculated air that is driven within the phenomenon of induction by introducing fresh air via a heat exchanger.

Solid Waste Management (SWM) has becoming a great problem for urban areas. Although directly transferring waste to landfill are is the cheapest solution, it is difficult to manage landfills due to some environmental problems. Therefore, reduction of solid wastes by means of recycling is needed. Benefits of recycling include recovery of valuable materials and volume reduction in landfill. Zonguldak Municipal and Medical Landfill Site have been operating since 2008. This facility also contains packaging wastes collection and separation plant. Nevertheless, recycling has not been started in Zonguldak city centre, except Bülent Ecevit University Farabi Campus. In this study, we investigated the cost of waste recycling in Zonguldak city centre. Total recyclable waste amount is calculated as 16876 kg/day. We found that 247 containers are required to temporarily store recyclable waste. Total cost of waste containers is 176605 TL (46844.8 €). Yearly recyclable waste transportation cost is 273567.5 TL, which is equal to 72564.3 €. The costs of new recycling waste containers require new investment; however, transportation cost is not a new expense. We only separated the transportation cost of recycled material from transportation of total wastes.

Written by Özgür ZEYDAN, Beste Nur KARAKAYA

Turkey, as a European Union (EU) candidate country, is harmonising the air quality limits to meet EU standards. For this reason, PM10 limit value is being reducing in yearly intervals till 2019 when daily PM10 limit value of 50 µg/m3 will be met.On the other hand, as the limit value decreases, the air quality of Turkish cities are being considered as polluted. The aim of this paper is to present the PM10 exceedance events in Turkey between 2014 and 2016. The daily measured PM10 concentrations were obtained from National Air Quality Monitoring Network of Turkey. We calculated the number of exceedance events. Then, we created thematic maps to evaluate the PM10 exceedances both spatial and temporal. There is an increasing trend in total number of cities where the PM10 threshold is exceeded. Moreover, there exist a decreasing trend in the number of cities in which no PM10 exceedance events occurred.It would be difficult for Turkey to meet EU PM10 standards in 2019 unless certain precautions are applied. At the end of the paper, there are some suggestions to reduce PM10 emissions and to meet threshold value.

Written by Özgür ZEYDAN, Burçin SUNAR, Zümrüt DANIR

Climate Change is the most important and the most complex environmental problem. There are two ways to deal with climate change: mitigation of Greenhouse gases (GHG) emissions and adaptation to new climatic conditions. To achieve mitigation goals, accurate quantification of GHG is required. For this reason, GHG emission inventories are prepared. In order to calculate all GHG emissions in the same unit (carbon dioxide equal) Global Warming Potential (GWP) is used. Adapting to new climatic conditions is more difficult. It must be known that, which sectors will be affected from climate change. Vulnerabilities of sectors are important in climate change adaptation. In this article, we firstly gave information about GWP. Then, GHG emission inventories of European Union member states and Turkey are represented and evaluated for the years 1990 and 2014. Finally, climate change vulnerabilities of certain European Union countries and Turkey are discussed. We mainly focused on the vulnerabilities of agriculture, forestry, water resources and human health sectors as a result of temperature and precipitation changes under the influence of man-made climate change.

LIDAR FOR GROUND SURFACE MAPPING IN FOREST ENVIRONMENTS

Published in Scientific Papers. Series "Journal of Young Scientist", Vol. 5
Written by Mihnea CĂŢEANU

Remote sensing enables the recording of accurate geomorphological data with the capability to efficiently cover large areas. However, the presence of vegetation makes the use of remote methods for terrain mapping difficult. LiDAR can be a solution for forestry projects, as the laser pulses can cross the entire forest canopy and reach the soil underneath. LiDAR data is stored as 3D point clouds containing the pulse returns from the ground or various objects above it (such as power lines, buildings or vegetation). In order to interpolate an accurate Digital Terrain Model (DTM), the points coresponding to the ground returns have to be extracted from the initial point cloud. This process is called ground-filtering or simply filtering. This paper aims to provide a performance analysis of multiple algorithms for LiDAR data classification. Algorithm performance is reviewed for the case of mountainous terrain, characterised by moderate and steep slopes and forest vegetation of a generally high consistency. Our findings suggest that the Lasground-new algorithm implemented in the Lastools software package provides the most accurate results, with a Root Mean Square Error of elevation values for the study site of 0.34 metres (with over 80 percent of the area having an elevation error of less than 0.20 metres) and an average RMSE for the field plots of 0.66 metres. Free algorithms such as Maximum Local Slope or gLidar provide relatively similar results in terms of RMSE. taking into account the difficult test conditions (topographically complex surface with dense canopy cover) we consider LiDAR data to be a possible solution for collecting geomorphological data for forestry applications, as long as a sampling of elevation at finer scales is not required.

DIRECT GEOREFERENCING USING UNMANNED AERIAL VEHICLES (UAVs)

Published in Scientific Papers. Series "Journal of Young Scientist", Vol. 5
Written by Constantin Răzvan CREŢESCU

Unmanned Aerial Vehicles (UAVs) have become an attractive data acquisition platform in photogrammetric applications. As we know, the fundamental photogrammetric and remote sensing problem is the determination with high accuracy of the attitude, the position and the intrinsic geometric characteristics of the sensor. At the beginning, the aerial photogrammetric systems had a fairly low accuracy position, but today’s, the new aerial photogrammetric systems allow the real-time determination of all parameters of exterior orientation with a good enough accuracy. Because of this, the advantage is that we can achieve direct georeferencing without needing to determine the coordinates of ground's control points, before or after the photogrammetric flight. In this paper I present some practical results of so called direct georeferencing of digital images, using of direct measurements of the image’s exterior orientation parameters by a GNSS/IMU system. This application is achieved by the aid of the collinearity concept, and just for a good accuracy estimation of the method, I have used few ground control points.

Hydro tehnical structures are part of the strategic structures of great importance in terms of environmental protection, due both to their environmental impact and potential environmental hazards. The reason for their importance policy is twofold: on the one hand, water resources controlled by these structures are of vital importance for sustainable regional development (water supply for the population, agriculture, power generation, etc.), and on the other hand hydro tehnical structures presents one of the greatest dangers given the energy potential of their destruction (dams, dikes) or potential hazards (ponds, wastewater). The paper shows the importance of monitoring the behaviour of hydro tehnical structures and to establish the vertical displacements towards the base and previous slice of instalment.

This paper aims to present some aspects regarding the cadastral work in Italy. Cassini-Soldner is a afilactic projection, from the deformation point of view, that is arbitrary, usually from arbitrary was passed to equidistant (preserves the distances on a direction). The Soldner method was designed in 1809 in Germany. It uses as orientation ellipsoid the Bessel ellipsoid (1841). In terms of surface projection is a transverse cylindrical, the cylinder's axis is perpendicular to the pole’s axis and the cylinder’s tangent is at the origin meridian. The origin of the system is on the equator, the X axis is oriented on the north and the Y axis is oriented on the east. Unlike Cassini-Soldner projection, the Gauss-Kruger projection is a conform projection from the point of view of deformations (preserves the angles).

The temperature is one of the most important climatic factors when it comes to land reclamation. The aim of this paper is modelling the average annual temperature for the year 2015 in Romania, in order to have information regarding the recorded values within the perimeter of the Horticultural Research Station, Cluj-Napoca. For the study area, a complex database will be created using spatial analysis specific factors. Spatial distribution of air temperatures is influenced by altitude, respectively there is a dependency between these two factors: air temperature decreases as the altitude increases. Thus, utilizing the data from the meteorological stations, the analysis aims to realize with the help of G.I.S. (Geographic Information Systems) techniques a map containing the average annual temperature for the year 2015 within the study area. The results obtained by this study indicate a temperature between 9.9 and 10.7oC.

MONITORING OF THE FREEZING DANUBE DELTA BASED ON SENTINEL-1/2 IMAGERY

Published in Scientific Papers. Series "Journal of Young Scientist", Vol. 5
Written by Giulia-Laura PANTEA, Anca-Simona LACUSTEANU

In January 2017, extremely low temperatures caused the freezing of the Danube Delta, leading to the complete isolation of some villages for a couple of weeks. The area was monitored from space, based on images acquired by Sentinel-1 and Sentinel-2, two satellite missions launched in the frame of the European Programme Copernicus. Sentinel-1 is equipped with a C-band synthetic aperture radar, while Sentinel-2 has a multi-spectral optical sensor acquiring data in 13 spectral bands. The spatial resolution of the GRD (Ground Range Detected) Sentinel-1 products used in this study is 10 meters, while the spatial resolution of the MSI (Multi-Spectral Instrument) Sentinel-2 products is 10 m, 20 m and 60 m, depending on the spectral band (B2, B3, B4, B8 – highest resolution, B5, B6, B7, B8a, B11, B12 – medium resolution and B1, B9, B10 – lowest resolution). The Sentinel-1/2 satellites collect complementary information that can be used for the frequent monitoring of vast areas, given the fact that each mission is composed of a pair of satellites (Sentinel-1A/B and Sentinel-2A/B). Sentinel-2B was launched on the 7th of March 2017 and it is currently in the commissioning phase. The present study aims at promoting the usefulness and adequacy of satellite data for monitoring the situation on the ground, especially when the area is not accessible by other means.

GLOBAL WARMING - TRUE STORY OR URBAN LEGEND?

Written by Anca BARCU

Global warming has been a controversial factor with polarizing supporters for many years. Initially, claims were made that global warming was a myth, given the relative short span of observed climate, but nowadays more and more scientists believe that global warming is a fact and this paper aims to prove that. From shrinking ice in Antarctica, acidification of oceans or CO2 emissions effects to temperature graphs, there is ample evidence that there are snowballing effects that will impact Earth mid to long term. More than 97% of climate experts agree that anthropogenic actions are determining a steady increase in global temperatures, with compounding effects on the environment.

Written by Maxim COROCHII

The degradation phenomena of river bank after afforestation still persists. The tree stands were established in 1998, and 1999. The method used for river bank stability was to establish tree stands mixed with unplanted stripes. The aim of research is to determine the water holding capacity of soil, due to the related events regarding water in soil. The phenomena of water moving through hydrophilic porous materials are conditional for land properties. Due to the aspect of mixed afforestation method, it was observed a difference opposite with expectations: water hold capacity should be very good (higher than 50% of dry soil weight) in tree stands. The mean of water holding capacity, determined in laboratory conditions, for soil located at the edge of tree stand is 19.47% of dry soil weight, and for soil located in the unplanted stripe is 30.53% of dry soil weight.

REMOVING HEAVY METALS FROM THE SOIL WITH PHYTOREMEDIATION

Published in Scientific Papers. Series "Journal of Young Scientist", Vol. 5
Written by Halil Burak ERTÜRK, Nizamettin ÖZDOĞAN

In recent years, urbanization, industrialization, population, domestic and industrial productions are increasing. However, organic and inorganic wastes are released into the ecosystem. Mining, urban or industrial solid, gas and liquid waste, pesticide and artificial fertilizer use, paint industry and car exhaust gases cause excessive release of heavy metals in nature. Some activities of heavy metals accumulate in there sulting soil. This accumulation is not just about soil and ecosystem. At the same time affects the food chain also human and animal health. These polluted soils are the most difficult work in terms of environmental engineering. The high costs of clean-up activities of contaminated soil have limited the use of classical disposal technologies limited.
Environmental engineers have also developed phytoremediation and bioremediation techniques to remove these toxic elements. The phytoremediation technique is more preferrable in this field, because of its environmental friendly properties and cost.The ability of hyperacumulator plants to absorb large amounts of toxic elements in their bodies mad ethese plant spreferrable in clean up activities. One of the most important advantages of the phytoremedical technique is that it provides in-situtreatment and it requires very few extra efforts to remove the pollution. In addition, phytoremediation does not harm natural resources. However, the phytoremediation technique can only be use in shallow regions in water, soil and sediment. Another short coming of their technique is that plants can not show their efficacy in very short time in highly polluted areas. For this reason, the phytoremediation technique can only be used at low levels of contaminated sites. In this review, the effects of heavy metals in the soil, the applications of the phytoremediation technique to remove heavy metals from the soil and the prosandcons of these methods have been studied.

Published in Scientific Papers. Series "Journal of Young Scientist", Vol. 5
Written by Alexandra-Maria GEORGESCU, Andreea DESPA

A novelty of our time is that humanity faces a global phenomenon whose consequences are still hard to assess by scientists, this phenomenon is global warming. Some people still doubt its existence however not only is it a real event but it is much more complex and urgent than it is considered to be. In the following reference we will evaluate if the phenomenon is favourable, dangerous or neutral for the global ecosystem. The idea of saving the planet may seem utopian, but it is necessary to think about the need to maintain a stable and beneficial climate in order to have an ideal habitat for human beings for as long as possible.
In this reference we also intend to describe the "fight" between those involved in climate campaigns versus climate skeptics / industrial groups. The ultimate goal would be to influence the audience and implicit, on climate policy making.

The river deposits transportation prognosis is required to draft the improvement planning of the torrential hydrographic basin, considering that the basin torrential potential shall be established based on this hydrological dimension, together with the retention capacity of the transversal hydro-technical works and with an estimation of the hydrological and anti-erosion efficiency of all the measures and works which are to be applied within the basin. The hydrographic network of the torrential basin Gurghiu is mostly dominated by the river deposits erosion and transportation. In order to calculate the annual average transportation the method advanced by R.Gaspar and by A. Apostol was used, a method which is conceived for the specificity of the torrential basins of our country. To draw a conclusion, based on the previously made calculations, the annual volume of the basin river deposits is of 130 m3/year. The bank deposits retention in the earthworks shall determine a stabilization of the river beds in the hydrographic works emplacement region, thus reducing its slope and depositing the alluvial deposits quantities.

Written by Beata KACZMAREK, Ewelina WERNER

The aim of this article is to present possibility of use of a metal detector, homing objects by generating a magnetic field, to identify unknown mass graves from the time World War I and World War II.
Mass graves are usually located in difficult, usually wooded area. Therefore they are inaccessible to the majority of archaeological methods such as aerial photography. Detecting the mass graves using a detector in this case is the best solution, because inside the graves are often found metal knives, buttons from uniforms, badges, or other such items.
For the prospecting research will be helpful VLF model which after appropriate setting detects a specific kind of metal.

Written by Ştefan PETRESCU, Roxana MUSTĂŢEA, Iosif NICORICI

In horticulture, recent technological advances has inevitably led to studies and research conducted on plants interactions with the environment, and further to the development of new theories and assumptions regarding the plants ‚senses’. A large part of the experiments conducted worldwide represents those that aim to understand the effects of music on plant growth, in various stages of development. In this context, the present paper aims to describe the influence of different types of music on the germination of Beta vulgaris L.var.cicla L. seeds. The seeds were divided into three groups (five seeds in each group), one subject to the experimentation and two control groups. Two control groups were chosen in order to establish if any differences could be noticed according to their proximity to the music source. The observations were taken twice a day, for 28 days, the total period of the experiment. Notes, photos, measurements for a better and fair description of the experiment have been taken. The results where rather unpredictable, proving the effect of music on plants in an unexpected way.

STUDIES REGARDING THE INFLUENCE OF MUSIC ON THE WHEAT PLANTS GROWTH

Published in Scientific Papers. Series "Journal of Young Scientist", Vol. 5
Written by Mihai Adrian RACHIERU, Irina IACOB, Maria CRISTEA

The positive effect of music not only on humans, but also on animals and plants is well known for a long time, being used in music therapy. Studies have shown that a harmonious musical concert stimulates songbirds from forests. Moreover, monkeys, depending on the nature of music they listen to, could cheer or fall into melancholy. If music is a mean of relaxation or even healing for people, which is its effect on plants? The current paper aims at answering this question, by presenting the results of an experiment that studied the biological effects of different genres of music on the wheat plants growth. The Triticumaestivum seeds were placed into three pots and the humidity, temperature and damping program were kept constant. One of the pot was set as the control group, the other two being subjected to the following musical compositions: Havasi - Rise of the instruments and Led Zeppelin’s tracks for 2 and a half hours a day. The experiment lasted 6 weeks, during which plants height was measured weekly and change in leaves color was visually estimated. The obtained results were in accordance with the literature data: both classical and rock music affect living biological systems, those exposed to classical music being higher and brighter than either the control group or those exposed to rock music.

This article aims to present the multiple perspectives that compete in defining public perception over global warming and the impact that several endogoenous and/or exogenous factors have on it. Due to the overwhelming amount of existing information, often conflicting and vague,we have confined ourselvesto try to identify common patterns - elements and differences in the discourse on global warming of different actors that have agreat impact on public opinion. We consulted materials provided by scientists, activists, politicians and public media and we have also aligned ourselves to previous research and studies on the controversy aroused by the subject of global warming in order to better graspthe complex relation between existing arguments and counterarguments and how theyaffect public opinion. In the conclusion section, we bring to attention some of the most relevant factors of confusion and misinterpretation that we have identified as leading to a continous dynamic of the public perception over global warming, thus contributing to a general state of confusion and insecurity.

Written by Robert STAN, George TOMA, Cătălin RADU

This article is based on a scientific report made by the Intergovernmental Panel on Climate Change of the European Commission. The information in the report shows that global warming is still ongoing and its effects are becoming clearer from year to year. It is good to know these things, but it is important to understand the causes: people are the main cause of climate change; less ice means more heat and the growing level of carbon dioxide in atmosphere has bewildering effects on creatures of seas and oceans. We bring into question the opinion of some political figures who are or have been skeptical about the warnings of scientists. In conclusion, the present paper doesn’t aim to form a general opinion, but rather to stimulate a debate.

Written by Vasile TIGANASU

The water system from arboretum is part of a complex project of landscaping (improvement) into the University of Agronomical Sciences and Veterinary Medicine of Bucharest (UASVMB) campus area. The aim is to valorise the park by harmonizing the natural space with the anthropogenic one. The water system consists of two reservoirs at different levels. Those are connected by a channel with a trapezoidal section and a pipeline that transports the water from the downstream lake to the upstream lake using a pump for water recirculation. The lack of natural water sources and the local soil high permeability imposed a waterproofing solution in order to reduce water loss. The channel path intersects an alley used by pedestrians and having auto traffic. For overpass it, there was built a bridge of reinforced concrete. The project in its entirety improves the landscape and social life of both students and employees of UASVMB and also of the people who visit the park for recreation.

Written by Mihai FRINCU, Corina DUMITRACHE

The aim of this paper was to understand how nitrogen cycle evolving through early experimental aquaponic system due to growth of nitrification bacteria such as Nitrozomonas and Nitrobacter. In this respect, it was design an aquaculture system, with different composition of fish species: Carassius auratus (10 pieces) and Hypostomus plecostomus (2 pieces). After we’ve found that the nitrogen cycle was established, we’ve chosen the suitable plants for the hydroponic system. The fishes were fed by organic meal; it was used a feeding rate ratio for design calculations of (0,6 grams /day) and the feed input was kept relatively constant. The pH was controlled on a daily basis (pH was maintained constant by addition of calcium carbonate) and oxygen dissolved (that has been kept constant by using a proper pump). Nitrogen forms (ammonium - NH4, nitrite - NO2 and nitrate - NO3) were determined on a daily basis as well and in the same time with pH measurement, in order to make correlations between evolution of nitrogen concentrations and nitrification bacteria growths. After 30 days of experiment it was found that ammonium - NH4 concentrations are directly and significantly correlated with nitrite -NO2 concentrations (the Pearson correlation factor is r = 0.74). It means that Nitrosomonas bacteria formed an effective biofilm. After 10 days from initiation of aquaculture experiment we also observed that nitrate concentrations values are correlated with nitrites concentrations values (which demonstrates the Nitrobacter growing). The correlation coefficient is negative (r = - 0.75) because in the absence of plants, the nitrates were accumulated in water. In conclusion, according to experimental data, the ammonium- NH4 and nitrite -NO2 concentrations are stabilized after 30 days, reaching values which are lower than legislation in force imposing.

Written by Marian Iosif GOMBOŞ

Natural honey was tested as a corrosion inhibitor for bronze in a simulated acid rain solution as Na2SO4and NaHCO3 (pH 5).Electrochemical investigations (potentiodynamic polarization and impedance measurements) showed that honey exert a protective effect against corrosion bronze and, in some cases inhibiting its effectiveness exceeds 93% at concentration level as low as 500ppm. Potentiodynamic polarization method indicates that honey acts mainly as a mixed-type inhibitor with predominantly control of thecathodic reaction. The presence of honey significantly decreases the values of corrosion current density. Electrochemical impedance spectroscopy shows that the inhibition efficiency increases with the increases of honey concentration.

The aim of this article is to present the research, which identified the prehistoric human’s relation to the natural resources that can be used repeatedly. For thousands of years human have been learning how to rationally manage nature reserves. The most interesting evidence of the prehistoric “recycling” is clay tablets with Linear B writing which were used in the administrative centre of one of Europe’s oldest civilizations – Mycenaean. It had been developed from about the seventeenth to twelfth century BC in the area of Greece. Clay tablets were not only made of a material that was used again, but they also contained inscriptions showing that Mycenaeans would mend and use again several of metal elements. “Recycling” could be used for the same reason for which we do it today as well – for the reasonable management of scarce non-renewable resources.

Written by Anamaria-Georgeta MĂRGINEAN

The aims of the present paper was to investigate the possibility of using the electrocoagulation method (EC) for the removal of Ni2+ and Cr3+ ions from the wastewaters generated at an electroplating plant from Transylvania area. In he investigated wastewater samples, the concentration of Ni2+ and Cr3+ significantly exceeds the maximum consent limits established by Romanian Standard NTPA001/2002. The influence of the varying operating parameters, such as the applied current intensity (4,5 and 6 A), electrode material (Fe and Al) and the contact time (10 to 60 minutes) on the heavy metals removal was investigated. The results showed that the removal of the metals from electroplating wastewaters solution increases with increasing current density and operating time. Using iron electrodes, over 99.64% of nickel and 99.39% of chromium ions were removed efficiently by conducting the EC treatment at current intensity of 5A, pH of 8.09 and EC time of 60 min. By using aluminium electrodes, the removal efficiency of Ni2+ was 98.21%, at pH 6.02, a current intensity of 5A and an operation time of 60 min.
