For generalized inversion, non L2-norm inversions have been widely used in geophysical inversion to obtain sharp and blocky models. However, problems such as the boundary of anomaly body obtained by inversion is not clear enough and the recovered residual susceptibility value is far less than or greater than the true susceptibility generally exist. In this paper a new 3D magnetic inversion approach based on residual node susceptibility is proposed. The residual node susceptibility model comes from residual block s...

In this research aim to determine the vulnerability of Moscow city using a geospatial based vulnerability index for sustainable development of the city. We use urbaniz...

Building a telecommunications system based on routers allows you to use traffic prioritization to improve the quality of user traffic, regardless of network technology. This new feature, compared to networks built entirely on hubs, is a consequence of the fact that routers buffer packets before they are sent to another port. The router usually leads for each input and output port not one but several queues, each queue having its own processing priority. The efficiency of the network depends on the capacity of the ...

The evaluation of the behaviour of natural stone applied in the built heritage of the historical centre of Porto city, Northwestern Portugal, classified World Heritage by UNESCO in 1996, has been carried out using a multidisciplinary approach in order to characterize both the rock that constitutes the main body of the building and the deterioration processes that have developed on the stone as a consequence of environmental and anthropogenic factors. Among an extensive and monumental historical heritage, built wit...

In parallel with technological and scientific developments in the world, people's choice on the materials is changing. In the light of these developments, mankind's environmental awareness is also increasing and thus the people aim to live in natural environments. In recent years, natural stones have started to be used widely especially inside and outside of the buildings in big cities in Turkey and the world. The low block efficiency of rocks caused to move the production of artificial stone in the construction s...

The irregularity of rock joints in rocky terrains contributes considerably to better mechanical stability of these terrains. The assessment of the stage of surface irregularities (asperities) of jointed surfaces in rock massifs plays an important role when shear strength of rock joints are evaluated. For this purpose it is necessary to analyze morphology of surface reliefs of rock joints. The digital replicas of surface reliefs are ideal tools for such a morphology analysis. This paper describes a new method for d...

Joints in rocky massifs usually form a space network that is hidden under the surface of terrains. Although normally invisible, same parts of such networks may emerge when excavation work is running in terrains. The irregularity of joint rock surfaces are characterized by joint rock coefficients that serve for computations of shear strength of these joints. This is important for evaluation of the mechanical stability not only the rock joints themselves but also for the mechanical stability of rock massifs that are...

This paper is a sequence that is part of the extensive analysis of the Danube Delta genesis. Sacalin island is a territory formed in the Black Sea, a short distance from the Romanian coast, in the south of the Saint Gheorghe branch of the Danube Delta, the main source of transport for alluviums. The history of this new territory is relatively recent. The first mention was in 1771. In 1856, Captain Thomas Spratt made a new map, in which the island of Sacalin appeared with two submerged nuclei. In 1924, Romanian res...

Erythromycin (E), a hydrophobic macrolide antibiotic, is prescribed for the treatment of acute bacterial infections, such as respiratory, urine, skin, and mouth infections. The main disadvantage of ER is its poor water solubility (2 mg/mL) that limits both formulation using hydrophilic bases and skin permeability. Cyclodextrins (CDs) are biocompatible cyclic oligomers of glucose, with a hydrophobic core and a hydrophilic exterior. CDs are used to improve the bioavailability of drugs by increasing their solubility ...

Generally speaking, a software interface may refer to a wide range of different types of interface at different levels: an operating system may interface with pieces of hardware. Nevertheless software interface can be use in order to extract a specific desired data format from a certain amount of data volume. In surveying, once with the topographic electronic equipment evolution, the possibility of getting field data measurements has very much increased as much as data volume but also as data quality. One of the m...

At uranium ore deposits surface waters and local streams are important for the environment. Because these are affected by uranium-bearing acid mine drainage and dissolved uranium is moderated by dilution and sorption uptake by stream sediments. Depend on the mineral alteration and in the case of the iron existence, acid drainage forms in the streams. In this case surface waters and streams become a significant mechanism for mobilization of suspended uranium particles. The aim of this study is to assess the acid mi...

The technology of microbial fuel cells (MFC) makes it possible to obtain electricity by eliminating and utilizing wastewater components [7]. The promising biological agents in the MFC are microbial associations. The presence of strains of different species of microorganisms allows consortia to consume a much wider range of compounds. Multicomponent makes them more resistant to negative environmental influences. An example of such associations is the sludge of treatment facilities. As part of most wastewater enteri...

Generally, there are 3 basic approaches to fire modelling. The oldest one is full scale modelling, than the small-scale modelling and finally PC simulation modelling such as FDS. If we compare the basic properties of these three approaches, we can compare following criteria. The most important is accuracy, relative costs, professional competence, time of preparation and very important is also the number of possible iterations within a short time period. The highest accuracy still belongs to full-scale models. Full...

Coal mining causes undesirable terrain subsidence due to caving in of the overlying rocks into the already excavated space. Subsidence deforms the terrain, damages structures on the surface and water flows, which results in the formation of inaccessible wetlands and swamps, and these areas need to be reclaimed. The problem of large flooded areas as a result of mining activities also concerns an area known as пїЅKozinecпїЅ, which is located between KarvinпїЅ and Doubrava in the Czech Republic. That territory has lo...
