Cutaneous leishmaniasis (CL) is known as tropical and subtropical neglected vector-borne disease in the Old World. Despite the fact that the Eastern Mediterranean Region and Tigris Basin are an endemic area of CL, unfortunately their bio-climatic and environmental variables are relatively poorly understood. The aim of the present study were determining the distribution of disease intwo endemic foci and comparison of variables in terms of CL epidemiology. For this purpose, extracted numbers of environmental variables from different sources and determined 3044 CL cases’ location information obtained from the ministry of health database to are used for modeling of the CL current probability of occurrence. The ecological niche model (ENM) analysis was used for this purpose. ENM analyses are made by using ArcGIS and MaxEnt softwares to explore the ecological conditions of the disease. Our results emphasized that CL current the area under the curve (AUC) value were found 0.868, 0.918 and 0.924 in Adana, Mersin (East Mediterranean Region) and Diyarbakir (Tigris Basin) respectively. Also, BIO1, BIO4, BIO5, BIO9, BIO10 and DEM were found related to the presence of native human cases of CL in East Mediterranean Region. BI O2, BIO4 and BIO11 were found to correlate with CL probable distribution in Tigris Basin. Consequently, there were relationship between temperature data and disease epidemiology for both areas. Also, comparison results of the study could be a reference to the health ministry's CL and vector control studies.

The paper aimed to present the advantages of realistic representation of a geographic area by combining optical and LiDAR data captured with UAVs. LiDAR data and aerial images, both captured with an UAV, have their own unique advantages and disadvantages and it is natural to integrate those two data sets for a good realistic representation of a geographic area in terms of horizontal and vertical accuracy. Compared with aerial images, LIDAR data provide more accurate height information but less accurate boundaries. Aerial images provide more extensive planimetric information such as high-resolution texture and colour information. Although 3D height information can be estimated from one or several images by the use of several photogrammetric methods, the height information extracted from aerial images is still relatively less accurate. The realistic representation of a geographic area in the virtual environment, was verified for validation in the Cernica Dam area, checking the spatial data sets used (LiDAR and optical). We used for data validation, the ground truth, given by GNSS measurements in the field, and the experimental results indicate that this combination improves the overall accuracy from 94% to 97%.

In the present paper the electro-kinetic depollution is compared with the thermal depollution. The need for a high degree of depollution for soils contaminated with liquid petroleum products is complemented by the economic need not to destroy the pollutant. The study contains a set of experimental data of laboratory activity to compare a new method of depollution with already known and industrially applicable methods. Thermal methods of depollution, combustion and desorption, are methods that have a high degree of depollution, but destroy the pollutant. Electro-kinetic depollution is based on physical principles that cause the migration of the pollutant for the purpose of collecting it without destroying it. The paper presents comparatively the degree of depollution rates achieved by the three methods and the costs obtained for them. In addition, for the electro-kinetic method particular attention has been given to both the recovery of pollutants and the properties of the water used in the process so that it does not become a new source of pollution.

In this study, it is aimed to produce pellets for use as solid biofuel from corn production wastes. Palletization of the biomass material increases volumetric heat value, reduces transport and storage costs, improves combustion properties, reduces emissions of particulate emissions, and produces a biofuel of the same size and shape. For this purpose, corn stalks were milled with a hammer mill and pellets were produced in an automatic feed pelletizing machine. Pellets produced from corn waste; hardness resistance, water absorption resistance, moisture content, ash content, equivalent moisture content, gas emission values released in the combustion result and calorific values which are important indicators of energy content have been determined. The upper calorific value of maize pellets with an average length of 17.28 mm and a diameter of 6.26 mm was determined to be 18.11 MJ/kg. The CO2, NO and NOx emission values of pellets from corn stalks were measured as 4.7 ppm, 38 ppm and 40 ppm, respectively. The evaluation of corn waste as pelletized solid biofuel will contribute to the prevention of agricultural land damage and environmental pollution as a result of the burning of residual vegetable waste from corn production.

Improving energy efficiency and reducing greenhouse gases is a central issue of the Europe energy strategy. The challenge of significant reduction in energy consumption is high. It can only be achieved if we all work together and share good experiences and practices. Recently in the livestock sector is highly relevant topic of the requirements for the breeding conditions of farm animals. These conditions are necessary for industrial methods of production and for poultry farming. They define health, ensure productivity and preserve the reproductive performance of farmed animals. The accumulation of products obtained in the process of birds breeding (heat, moisture, waste gases, etc.) in the premises may have a negative impact on the health of the birds. Correct determination of these products will result in the exact sizing of the ventilation and heating installations of poultry farms. This article identifies the incoming and outgoing heat flows from a broiler farm and proposes a methodology for determining the amount of energy required for heating the farm by providing the necessary zoo technical parameters for broilers breeding. The methodology has been developed on the basis of European and national regulations in the field of energy efficiency and in the field of veterinary medical requirements for livestock premises. The proposed methodology could be used for designing of heating and ventilation installations of poultry farms operating under different conditions.

Increasing energy efficiency and reducing greenhouse gases is a central issue in the European energy strategy. The challenge of significantly reducing in primary energy consumption is great. It can only be achieved if we all work together and share good experiences and practices. Vegetables are undoubtedly one of the healthiest foods with high energy content. They are rich in amino acids, easily digestible sugars, enzymes, minerals, vitamins, chlorophyll, organic water and other nutrients. Therefore, the production of fresh vegetables is a vital necessity, even in winter. Naturally, winter production of vegetables requires that they be grown in heated greenhouses. Energy costs for greenhouse heating and ventilation form a significant share of their total production costs. The purpose of this paper is to identify the incoming and outgoing energy flows from a glass greenhouse for vegetables production and to propose a methodology for defining the energy for the greenhouse heating while providing the necessary parameters of the environment for fresh vegetables growing.

The paper presents displacements and accelerations of two tower type buildings, one near the epicenter zone, Vrancea and one South of Bucharest (~150 km from epicenter zone). Displacements and accelerations were computed from the processed recorded accelerograms. Were used 3 “Triaxial Seismic Accelerometers” on 3 levels of each building. The displacements and accelerations on the analyzed structures were a result of Vrancea medium earthquakes between 2014-2017 years with magnitudes Mw ranging from 3.8 to 5.6 and depths between ~ 41 km to 147 km. A discussion of structural response was made concerning each building (one on 12 seismic events, the other on 6 ones and both on 4 that are common). The recorded data will contribute to a better understanding of the structures responses, even subjected to medium magnitude seismic events, and to the mitigation of seismic risk for densely populated areas.

The erosion generated by water, called synthetically water erosion, especially caused by the stream of water induces, the continuous change of the watercourse with significant imbalances of form and path, but also if it is the aquatic ecosystem, or a series of many others negative changes in the riparian areas of the minor riverbed, with material damage and sometimes clear loss of human lives. In time, constructive measures have been developed and applied, located in the riverbeds, to manage and minimize the impact of this phenomenon. The monitoring of the behavior of these works shows the beneficial effect on the limitation of erosion, but it also reveals the negative effects of the hydrodynamic action of the water on their structure and stability, eventually on their durability. The present paper proposes a synthetic analysis of the causes and ways of degradation of the main types of works used in engineering practice to limit the erosion of the watercourses. The analysis is based on an extensive documentary and field study carried out on concrete cases, on a series of rivers in the river basins of Moldova. The causes that led to the observed degradation are highlighted, respectively the solutions by which these shortcomings could be avoided in the future. It highlights the increased efficiency and the longer life of the new types of works used for this purpose, respectively the works based on the use of geocontainers.

This research aims to identify the manner in which orographically factors influence the horizontal precision of GPS coordinates. The study area is a mountainous region in the Bran locality, mainly covered with spruce forests. Data was collected using the Stop&Go method with post-processing, using two GPS receivers (Trimble Pro XH and Pro XT). Data was stratified considering the following criteria: orography (valley, slope, crest) and aspect (S-N, E-V). Field data was post-processed and the resulting precisions were analysed using the Statistica software. The influencing factors were analysed individually, but also in different combinations. The best accuracy was obtained for points located on crests, followed by points on slopes (which had a good precision) and finally points in valleys (which had acceptable or low precision).
