Safety monitoring is of particular importance for building structures at the end of their lifetime what could endanger the health and lives of people. The use of geodetic robotic measuring stations enables the automated acquisition of coordinate data on the spatial position in the key locations of the monitored building construction and from them to evaluate geometric deformations in real time. This concerns the monitoring of large roof structures of sporting arenas, particularly in winter under snowfall impact, o...

One of the natural gas advantages, as primary energy source, is the opportunity to store it in large volumes under the same state as it is used by the final customers, without being subject to any state modification or conversion in another energy type. Gas depleted reservoirs are the first candidates for turning into underground storages, as the storage process is closest to the production process, but also due to the availability of a large amount of data which makes the reservoir to be well defined and also due...

Renovated historical army barracks have been turned into residential buildings, administrative and educational facilities, museums, even churches. Depots, garages and warehouses facilitate entrepreneurs and freight forwarders. Airports serve the needs of civilian and leisure aviation. While these functions have all been successfully introduced into historical post-military architecture, saving it from demolition and vacancy, t...

Romania has an important rail network, of public use, consisting of about 10764 km of railway, some of which are affected by instability phenomena. Although the percentage of areas affected by instability in the entire network is insignificant, railway sections have some peculiarities, any difference in the order of the centrimetres appearing at the upper level of the rail can lead to the closing of the line, with important financial consequnce. The surface, affected by the instability phenomen was about 4,000m2, ...

Numerous errors and misinterpretations concerning the group refractive index of air are present in fields of geodesy and metrology. Many historical methods (e.g. Barrell and Sears, Edl?n) are still in a frequent use even if they are considered obsolete and inaccurate from today?s perspective. The goal of this paper is to interpret and evaluate Ciddor and Hill procedures which were published in Applied Optics in 1996, 1999 and 2002. Along a simplified method, articles by Ciddor and Hill from 1996 and 1999 were reco...

The determination of bitumen dosages for asphalt mixtures using empirical or semi-empirical methods (the specific surface method being the most well-known) no longer meets national or international technical standards. Most countries require the use of methods for determining the optimum binder content by laboratory tests grouped, usually, on several levels according to the Marshall or Superpave mix design. Romanian technical standards in this field are European and national standards, which unequivocally impose w...

The Intersect Drilling method is a modern drilling technique for HDD (Horizontal Directional Drilling), giving a completely new dimension to Horizontal Directional Drilling technology. Its creation was mainly due to the need for drilling in difficult conditions, where drilling with the use of only one drilling device is often impossible or ineffective and could end in the failure of the entire project. To cope this it is necessary to apply modern solutions in this technology. One such solution is the Intersect Dri...

In the process of growing organic products farms face many problems including the need to treat phytopathogens without fungicides or to increase yields without mineral fertilizers. In organic farming, agents of biological control as well as nonconventional organic fertilizers can be used to achieve these goals. One of the main problems with biocontrol agents is that their survival after introduction into soil may be very different since it depends on many biotic and abiotic factors in soil ecosystems. The problems...

Preservation at positive temperatures is limited in time. The common technique to reduce metabolism is by reducing the temperature below ambient, using refrigeration or cryogenics. Therefore, these methods are used to preserve biological matter (cells, tissues, organs, vegetables, fruits etc.). Preservation at negative temperatures is possible with limitations in time and imposes also other biotechnological challenges. Long term preservation below freezing temperatures is not successful yet for organs and tissues....
