Simple and cheap methods for the study of building stone deposits for the production of blocks of commercial size can be used to make geological work more efficient. However, physical processes in a massif are hard to understand when doing geophysical research, and the effect of microstructural parameters, mainly the microfracturing of rocks, on geophysical field indices is poorly understood. The authors have studied the impact of microfracturing on the physico-mechanical properties on coarse- to giant-grained rap...

The heliostat structure and shape must deliver the essential rigidity to accurately reflect solar radiation onto the target under several working conditions. Therefore, the aim of this study is to investigate the effect of various rectangular heliostat shape aspect ratios ? =L/W on the spiral layout performance considered by keeping the same heliostat area. Here ?L? and ?W? are the length and width of the rectangular heliostat shape respectively. A combination of an-inhouse developed computer code based on the vec...

This paper focuses on a study regarding the use of waste in constructions: such as blast furnace slag from ironworks, as a by-product of the iron oxide reduction reactions by carbon monoxide resulting from coke burning. The slag is used in cement-based mortar mixtures under two forms: as granulated and ground slag powder under 63 ?m and non-granulated slag as an 0/4 mm aggregate resulting from solid slag, processed in crushing equipment and then sorted according to the standards on mortar and concrete aggregates. ...

Salinity is one of the major environmental stress factors for crops that adversely affect plant growth and development. High concentrations of salt in the soil cause ion toxicity, osmotic stress, oxidative stress, nutrient deficiencies and imbalances perturbing important physiological and biochemical processes. To minimize the effects of salinity, the plant develops a large array of responses involving a complex enzymatic and non-enzymatic antioxidant system, ion transport and compartmentalization of deleterious i...

According to the Aridity Index (R), at the level of the Eastern Romanian Plain have been identified certain areas of aridity intensity, differentiated from the West to the East as a result of the degree of continentalism increasing, which also led to a specific geobotanic zoning (the forest area, the interference between the forest-steppe, ante-steppe and steppe). The degree of vegetation coverage is an objective indicator of susceptibility of soil and/or land to degradation processes, which are manifested on larg...

The current article makes a comparison between the Web Mercator and Mercator projections, the former being frequently used for web mapping and visualisation applications. Web Mercator shows some significant differences from the Mercator projection: the Earth is approximated to a sphere, it is not conformal and the rhumb lines are not represented as straight lines on the plane. Both map projections were compared here with one another for representing Romania. Through Web Mercator, a shift to the North was found whe...

Cross-dipole acoustic logging traditionally uses to study the anisotropy of the formation acoustic properties. The method is based on comparing the velocities of fast and slow shear waves and calculating the anisotropy coefficient. In the anisotropic formation, the flexural wave is splitting into two modes. The amplitude of cross-components XY and YX will be non-zero and significant in the anisotropic zones of the formation. There are several approaches to assessing the presence of anisotropy in a formation. As a ...

Geomonitoring of a mining infrastructure has a crucial impact on company?s proper functioning and safety. For many years one of the most popular monitoring methods in Poland was to measure the tangent directions at multiple levels of a slim construction such us headframe or chimney (bisector intersection). Modern methods contain also GNSS measurements. However, the best method to generate a true shape is TLS measurement and 3D model preparation. Analysing such model, it is possible to determine not only the maxima...

Romanian forest and vinicultural ecosystems were strongly affected by climatic changes, especially during the last two decades. The main changes manifested in the health state of these ecosystems were analysed based on data from national monitoring, forest management plans, as well as from national forest statistics (in the case of forests). Furthermore, harmful insects were inventoried and captured with adhesive yellow traps and analysed together with moths captured with traps containing Atrabot synthetical sexua...

With the rapid development of Turkey?s petroleum industry, oil production, the way of burning crude oil to produce steam, need to change. Heavy oil reservoir with thin layer or edge water is unsuitable for thermal recovery. Electric heating leads to considerable electrical consumption. Low injection water temperature decreases reservoir temperature and increased crude oil viscosity. The prolonged temperature difference break up reservoir pore throat cement and framework minerals. To improve high-capacity channel c...
