Remote sensing techniques were used to detect the heat islands over the Romanian region, based on multi-temporal Meteosat Second Generation, Land Surface Analysis Satellite Applications Facility/ Land Surface Temperature products (MSG LSASAF/LST). A method was proposed for the rapid and accurate mapping of heat island areas based on the combinational use of normalized land surface temperatures. In order to do it, the IDL routines developed locally have been used. It was studied 2976 LSA-SAF/LST images acquired dur...

Investigations of explosive consolidation technology of nano sized Al, ultra-disperse Ni and Ti powder compositions are discussed. The mixtures of ultra-disperse Ti (Ni) - nano sized (<50nm) Al powder compositions were consolidated to full or near-full density by explosive-compaction technology. The emulsion and ammonium nitride based industrial explosives were used for generation of shock waves. To form ultra-fine grained NiAl and TiAl intermetallides with different compositions, ultra-disperse Ni and Ti particle...

In order to prepare minimal feature vectors to be used in a Content Based Image Recognition (CBIR) system, we are proposing methods that can accurately identify the main colors contained in a digital image. The methods use the “LAB” color space properties that allow for all the colors of the same intensity or luminance “L” to be placed uniformly in the same “ab” plane. Basically, RGB images are first preprocessed: trimmed, scaled and transformed in the LAB color space. Then (a,b) pairs, corresponding t...

The authors while examining the real estate market for estimating the market value of real estate have defined the areas directly affecting the state of the ecosystem. Using a very simple and inexpensive test, they identified anomalies at the fiscal level of state and estimated negative effects of legislation on the ecosystem. The main research tool was a comparative approach in estimating the value of the property.

In this work, samples were taken from Koyunagili Lignites Company Washing Plant feed and were subjected to extensive research to determine the floatability of lignite fines.

Continental intraplate magmatism commonly leads to formation of subvolcanic complexes, for which it is important to characterize their mantle sources. It is necessary to distinguish between the effects on the mantle signature of fractional crystallization and the assimilation processes during magma ascent and its residence in the crust before the final emplacement. Elucidation of these processes requires besides information on Sr and Nd isotopic ratios also detailed geochemical data, especially information on conc...

For the purpose of defining location of points, coordinates that described according to a reference systems are using which parameters has defined already. In surveying, the base element is ground control points with their known coordinates in a reference system. In every kind of surveying project, new coordinates are determining by using coordinates of ground control points. Because of this, the projects realized by using points which have low spatial accuracy and ground control point’s location errors will be ...

Hydrogeological features of the quaternary sediments lies in different assumption for the emergence of freatic accumulations of groundwater and the ability to power or, conversely, to some extent seal underlying aquifers. Effect of the opencast mining on activities of quaternary sediments is significant and consists primarily in a drainage effect. In places, where the overburden works crossed saturated parts of the quaternary cover, there is a sudden drainage of aquifers. This water vents are regularly cause unres...

A review of available drought analysis is given, with focus on the studied region. Temporal and spatial var...

In connection with high basicity requirements for current agglomerates it is necessary to keep their iron content. This requirement can be met by increasing the content of concentrates in sinter mixtures. It is important to clarify the limit of the concentrate addition or volume in current sinter charges. For this purpose in view laboratory sintering tests were performed to investigate the effect of sintering ores and concentrates on the agglomeration process and its products. The main charge components were mixed...

When infrastructural routes pass through sites with a long-term natural balance, landslide processes may be instigated. The reason is the human intervention. The scale of this intervention is usually sufficient to break the balance border between the admissible human intervention and nature. Crossing this frontier is followed by increased expenditures and termination of construction activities. The subject of this paper covers not only the measures for the ecological balance to be efficiently restored. Attention i...

The X-ray electron probe microanalysis (EPMA) technique is developed for cassiterites and minerals of Ta and Nb. The phase and chemical composition of rare metal pegmatite cassiterites of the East Sayan Belt and their inclusions of Ta and Nb minerals were studied using the EPMA technique. The results of cassiterite investigations showed, that niobium and tantalum are contained both in isomorphous form, substituting the tin in the matrix of mineral and as mineral inclusions of columbitetantalites.

The mineralogical analysis is a highly effective method of prospecting diamond-hosting rocks. The main goal of investigating kimberlites rocks, the primary source of diamonds, is to examine the mineral composition of kimberlites. The microprobe analysis is currently the principal method to define the compositions of megacryst minerals from kimberlite rocks. In addition, determination of the groundmass mineral composition is important for evaluating the diamond potential of kimberlites. This paper presents results ...

An ultrasonic sound wave has been used in rock mechanics to determine rock properties for many years. Because it is a relatively simple, low-cost and non-destructive testing method compared to others. Water content, porosity, and cracks in the rocks structure are some of the most important parameters for P and S-wave speed. In Rocks, under uniaxial compression stress, the account of space inside the compressed rock is reduced while an ultrasonic sound waves speed is increased. However, after a certain level of com...

Waste management is common problem for many countries in world and landfill site selection is a necessary issue for waste management in fast-growing regions. Likewise, appropriate landfill site selection should be performed for each municipality in Turkey because municipal solid wastes are major problem for especially drinking water basins. The main objective of this study is to selection of a landfill site in the Yalva\cc Basin. The basin is located at east of the Egirdir Lake which is the second largest fresh wa...

Landscape fragmentation, a process where biotopes are separated into different parts by a creation of a barrier, is a key issue of landscape ecology nowadays. Separated landscape patches gradually lose their potential to fulfil their original function. There is general effort to develop universal model or set of indicators for fragmentation measurement. In the CR we carried out research project “Integration of landscape fragmentation issue into the decision-making processes” leading by the Ministry of by the M...

The aim of the Bologna Process is to promote the European system of higher education worldwide, remove obstacles to student and academic mobility within Europe, and bring increased career opportunities for students and teachers in the European employment market. Since 2003 Russia has been involved in the Bologna process. Perhaps the task seems to be extremely ambitious. But we hope it will help us to change the situation with foreign languages acquisition for the better. A significant number of educational experim...

Lead (Pb) mobility in soils and hence its availability for plant uptake may be influenced by several soil properties, some of which are modified by sludge application. It is therefore imperative to understand how these modified properties affect Pb concentrations in different geochemical fractions of sludge-amended soils. Vertisols are common in arid- and semi-arid areas and are used extensively for agriculture. This study aimed at determining the relationship between selected soil properties (pH, organic matter (...
