Within the framework of the new socio-developmental paradigm, the doctrine of planning and the realization of residential buildings in Slovenia has also been changing. Based on an analysis of typical examples of "constructing for the market" we have established that nowadays the economic performance of the investment and the formal technological norms are exclusively prevalent among the project's starting points. To improve the conditions, suitable tools will have to be efficiently introduced into the national legislation. Source

Laboratory and in-situ shear tests of walls strengthened with Carbon FRP (Fiber Reinforced Polymer) strips and Glass FRP grid were compared to the results of different calculation models for masonry with FRP. Tests on new and old solid brick specimens showed an increase in shear strength and ultimate displacement. The best results were obtained with horizontally and horizontally-vertically epoxy-bonded strips and modified cement mortar grid configurations, worse with diagonal strips due to peeling failure. ACI and CNR calculation approaches showed the best agreement with experimental results. Source

The paper introduces the issue of man-made climate change as well as social, political and technological development that led to the construction and spread of the ideas about the ability of geo-engineering inter entions to mitigate expected climate changes. At the same time geo-engineering, defined as large-scale environmental engineering able to counteract the changes in atmospheric chemistry, is observed together with the concept of risk society as well as technological attempts to resolve contemporary problems that are at least partially of socio-cultural and not only of technical or natural origin. The central part of the paper presents an overview and categorization of specific geo-engineering techniques considering their mechanisms, supposed theoretical efficiency to reduce global warming and possible unintended negative consequences. The paper also discusses the potential of mentioned geo-engineering techniques for purposeful adversarial use in the sense of dual-use technology. The concluding part summarizes the findings from the analysis and identifies geo-engineering techniques that involve the least risk. The paper also discusses the position of technology and risk in risk society, as well as possible dangers of the commercialization of geo-engineering that might, through post-academic models of science, lead to the normalization and implementation of those geo-engineering techniques that have the highest potential for side effects.

During operation, bridge condition is decreasingdue to various effects. The condition is described by "condition rating coefficient", determined byvisual assessment Condition of Slovenian state road bridge network is analyzed. The condition rating database is structured with respect to traffic load, climate zone, structural material, structural type and bridge element Changes of condition rating coefficientwith timeare presented and analyzed. Results show that climate and exposure to water are the most important parameters influencing the condition of bridges. Challenges related to assessment methodology are identified and discussed.
