World production of pipes is mainly based on the standards of API. However, this does not obligate you to use exclusively for casing manufactured by API standards. The wells that will exploit the hydrocarbons and aggressive media, install the protective casing made of alloy steel not yet covered by API standards. Running casing operation holds a sp...

A steady increase in the number of dogs is a serious sanitary-epidemiological problem of urban areas. Those animals permanent contaminated those areas with faeces which present a significant health problem from human. Most frequent parasites are eggs of zoonotic helminthes Toxocara canis, Dipylidium caninum, Ancylostomidae spp., Taenia spp., Toxasc...

Implementation of major construction projects thanks are due to the technological development of materials and equipment to perform. Development of equipment for piles, allowed this type of structure a large application, as in the system of basic structural elements, as well as providing (temporary or permanent) construction site. Influences on the...

The state of stress around cavities of the revolving ellipsoidal shape (prolate or oblate) in the extreme cases of their degeneration is a very complex problem. Namely, the shape of cavities is defined by an appropriate curvilinear coordinate system, which contains hyperbolic and trigonometric functions. In this paper, the treatment of revolving el...

The landslide is located in the hinterland of water source "Studenac" in the local community Gornja Cadjavica near Bijeljina. The field where the triggered landslide occurred is conditionally stable slope. It is overgrown with forest trees and therefore it was not a subject of interest in terms of its stability until the water source and accompanyi...

The hydrogeological investigations are inevitable in the whole process in defining of engineergeological field characteristics and the drafting of landsllides rehabilitation project, but the main goal of these investigations is the groundwater quantities calculations in critical sections of landslides. For gain of exact input parameters for groundw...
