Related to assuring the sustainability of our human society the technical field is playing an important role, beside the environmental and socio-economic field. Taking into account the technical field in connection with the social one, special attention has to be paid to the field of cartography. This is becoming more relevant than ever regarding assuring the sustainable development on a regional level because of the need of land property clarifications. A lot of progress has been made in the last years in the fie...

Digitization and publication of old globes on the Internet allows the public a detailed inspection of globes that are normally encountered only in a limited way. In the collections of memory institutions two forms of globes can be found. In the first case there are the classic spherical globes placed in decorative stands. In the second case the globes are stored as a set of globe prints. Such globe prints usually consist of a series of globe gores and two polar caps. This paper deals with the issue of creating dig...

Hydraulic fracturing is a widely used in the hydrocarbon production industry to stimulate oil and gas flow from traditional and shale formations. This technique is one of the essential elements of borehole mining technologies and is designed for controlled impact on the rock mass during the development of solid, liquid and gaseous mineral resources. The creation of a system of traversing cracks in the rock mass that are parallel to each other is of great practical interest for many geotechnical issues such as impr...

Heavy-metal pollution of forest soils around closed mines represents an important environmental concern and we measured the contamination level in the forest plants. The waste material generated by the now-abandoned ore-processing plant of Tarni?a-Suceava, Romania, situated in the Eastern Carpathians, contain large amount of heavy metals, aluminum, and arsenic. The high risk of environmental contamination of sterile dumps is amplified by their susceptibility to airborne, hydromechanical and hydrochemical transport...
