The capacity of one material synthesized from ash to remove Cu2+ from aqueous solutions was evaluated. Adsorption kinetics measurements were performed at 298, 308 and 323 K and thermodynamic parameter was calculated. The adsorption process was found to be feasible and spontaneous due to negative value of Gibbs free energy (-6.91 kJ mol- 1 at 25 °C). Kinetic studies have been carried out to evaluate Cu2+ adsorption using a number of three parametric equations: the pseudo first order, pseudo second order and intra-particle diffusion model equations. Results obtained showed that for all the studied temperatures the adsorption process follows a pseudo second order kinetic model, which demonstrates that the chemical adsorption process is predominantly.

The paper deals with the phenomena developed when along the surface of Earth to the well known Coriolis force some reactive forces are opposed. Since, usually at that level, the Coriolis force is a weak one only long lasting interactions become of practical interests. Regarded from this perspective the Coriolis force is first mechanically defined. Its actions in horizontal and vertical planes are further detailed. The conversion law of energy from an inertial system to a non-inertial one is also presented. As a tribute to History of Science the existence of Coriolis force is proved by the Foucault pendulum. Reactive forces to the Coriolis one are usually developed by engineering works like the protection walls of river banks. For such works the Coriolis force acts as a long lasting disturbing action. Like gravity it is a permanent action, but horizontally directed. During the long service of the works, due to imminent soil deformations some structural damages could occur. According to the clause 2.5 of Eurocode 1 the durability of engineering works should be evaluated. The Coriolis force is a determinist entity while the durability is a probabilistic one. As it was already shown in our paper [6] in 2011, this requirement can be reached with the aid of the Mathematical Theory of Reliability only. Considering several computing schemes for reactive forces, the paper is suggesting a range of numerical values for the risk factor. By including in durability analysis the influence of Coriolis force the results are more reliable and faithful to reality.

3D Laser Scanning is providing a detailed, reliable, and accurate solution to many surveying and measurement problems, and has become well adopted for complex applications, like plants and other facilities, where accurate threedimensional detail is critical for efficient design and construction projects. Terrestrial laser scanners deliver a dense point-wise sampling of an object’s surface. The most typical example is creation of a 3D As-built model. This paper describes a typical scanning project from field-to-finish . In many respects, laser scanning follows the same general surveying process as other instruments: data is collected in the field, adjusted to the appropriate coordinate system, modelled and relevant features are extracted to produce 3D CAD drawings, 2D precise plans and elevation, etc.

The paper aims to emphasize the performance of confined masonry with polymer grids comparing to masonry with steel reinforcement, in terms of energy consumption, strength and stiffness. In the state-of-the-art there are two known types of masonry. The first type is the original brickwork, composed of burnt soil brick units bonded together with lime mortar. The second type is made of ceramic bricks burnt up to the point of vitrification, using cement mortar. There are important differences between the two types of masonry, which confer them different properties. Masonry is reinforced in order to increase its resistance to seismic activity. Original masonry can be reinforced with non-metallic, polymerbased reinforcements, while the modern masonry is reinforced with steel reinforcements. Energy consumption needed to produce a building will be carried out by calculating the embedded caloric energy that includes phases of production and transportation of materials: bricks, mortars and reinforcements. An ergonomic calculation will indicate the mechanical work needed for the construction of the two compared situations: original and modern reinforced brickworks. Increased elasticity and strengthen to earthquake in these two reinforcement situations is shown by a dynamic and modal analysis of structure with adequate software. The analysis will be made on two models taking into account requirement of seismic design code on plane and vertical irregularity.

This paper presents energy as an important factor for the development of the Danube Region and all the countries involved in the European Union for the Danube Region. Energy is one of the challenges all confront because of the high prices, unformed markets, low usage of the renewable sources, low efficiency and lack of connection between different countries. Trough this paper is highlighted the importance of the Danube Region from energy point of view. The Strategy for the Danube Region is a new way to overcome 20th century division and conflicts in the Region, and as an important impulse for overall socio-economic development. The involvement of non-EU countries in the Danube Region Strategy is a key priority to the macro-regional cooperation.

It has been said that something as small as the flutter of a butterfly´s wing can ultimately cause a typhoon halfway around the world. Chaos Theory effect can be applied in an actual climate change issue. Forests, fields, gardens, and natural areas are being replaced with concrete, bituminous and unnatural surfaces. Necessity of recovering green spaces and natural areas is becoming more critical. Questions of sustainability, improving quality of life, solving current ecological issues are goals urban and architecture community can solve. Key factor of not forgetting about nature we have been given is designing healthy green cities, covering building in plants, integrating wildness in cities, designing and constructing vegetative roofs, living walls, implementing green policies. Integrating nature to city may seem fashionable, expensive and not necessary. Microclimate and building´s ecological footprint is very high. Balance of artificial and natural environment is way how to maintain sustainability. Co-operation of landscape and dwelling is bringing nature to city. Green is one of the key elements in environmental strategy. Balance means minimizing of breaking close ecosystems. Designing one big artificial ecosystem that wouldn´t be destroying real natural ecosystem is the goal of this paper. Urban ecology and environmental issues need to become an integral of development, construction, policy and way people think. Green roofs and living walls offer solutions how to find a place for nature in designed world. Positive approach on local scale may cause positive worldwide impact. Like the flutter of a butterfly´s wing.
