The objectives of the present work are to develop technologies for the electrodeposition of mixed oxide nanocomposites with electrocatalytic activity towards the oxidative degradation of organic compounds. Oxidation of organics in the potential region of O2 evolution is supposed to proceed through the oxidation of water to hydroxyl radicals, which then may either be further oxidized to give molecular oxygen or interact with organic molecules in an oxygen-transfer reaction. Therefore, the ideal electrode material m...

Blast pattern design has direct influence on the time consumption and construction cost of drilling and blasting of tunnels. Tunnel blasting is more complicated operation than open pit blasting because the only free surface that initial breakage can take place toward is the tunnel face. The most important operation in the tunnel blasting procedure is to create an opening in the face with the intention of develop another free surface in the rock. This is the function of the cut holes. The cuts can be classified in ...

A significant element characterizing a lasting development in Braila Plain region, but also in any other similar area, would be an environment factor i.e. the water, with an increasing importance when considered against the high dryness background. Generally speaking, both the consumed water and the consumption structure reflect the quality and quantity of water resources and, implicitly, the economic potential of the region at issue. As for Braila Plain, here there is a paradox to be considered : even if the regi...

The climate, morphometric and lythological conditions confer certain peculiarities upon the waters resources of the northern-eastern Romanian Plain. One can say about the Braila Plain hydrographic network that it is poor and this is due to the discharge, situated under the value of 1 l/sqkm, but also to the very low relief energy. The allochthone rivers : the Danube, Siret, Buzau and Calmatui are affected by the refief climate conditions and also by the size and the geographic position of the hydrographic basins.

Gole-Gohar iron ore has located in IRAN. Reduction of costs at this mine is too effective for mining benefits. One of the important parameter about these costs is the pit slope support with control blasting operations. In this project, we try to use the buffer blasting method for suitable pit walls. Buffer blasting is a method that uses the faults for smoothness of pit walls. In this method, we do not use the control holes. So, by using the buffer holes, the control blasting operation will be suitable. Besides, th...

The treatment of natural rock, as well as construction aggregates and ornamental rock creates a great amount of residues, which are usually grain sized under 100 $\mu$m and with chemical and mineralogical composition modified due to processing. Therefore these materials have a composition with a variable content of rock, accompanied with other components as iron particles, clayey materials, flocculants, etc. These contaminants limit the application of those wastes. It is necessary therefore, the search of a proces...

Wetlands are important habitats consisting in true biodiversity pools. Human pressure had a continuous negative impact during time, i.e. significant changes, or more, irreversible, where the area of oligothrophic bogs has been reduced. Our observations have been carried in Tinovul Mare–Poiana Stampei Natural Reserve, situated in Dorna Depression (The Oriental Carpathians) at 910 m altitude, with 677 ha. This is the largest peat bog in Romania. The main goal is focused on all biotic and abiotic factors which are ...

This paper presents the outcome of the study on the compaction and consolidation behaviour of class F fly ash of Talcher Thermal Power Station (TTPS)of India for stowing in the underground mines.

Mine ventilation has a key role to improving underground working conditions. Ventilation is required to clear dust, gas and toxic fumes from blasting and removing exhaust fumes from diesel equipments and also required for cooling the workplace for miners in deep hot mines. Ventilation systems need to take many possible modern mining scenarios into account, and costly infrastructure is needed to serve future ventilation and cooling requirements. To enable the practical and economical design of mine ventilation syst...

Vlasina lake in Southeast Serbia is classified as an Area of Distinct Land Use. Due to high environmental protection standards, the Master Plan of the area forsees the need for high levels of protection from waste water, storm water, and sediment. The storm waste water and sediment management system implies infrastructure that consists of open channels and gutters, leading to detention basins. Prior to release into the lake, storm water and sediment from the immediate lake bank area are treated and managed within ...

It is generally agreed that education in environmental pollution and protection of the environment should begin at the primary school level. It can even be argued that teaching about the environment at the primary school level is a national duty. In recent years Turkey is paying greater attention to the threats of global warming and environmental pollution as part of their adaptation process to EU laws and regulations. In this study we tried to determine the cognitive and affective levels of primary education stud...

The uniaxial compressive strength (UCS) is one of the important input parameters used in rock engineering designs of underground spaces, or rock blasting, drilling, slope stability, excavation rate and many other civil and mining operations. Although, the method is relatively simple, it is time consuming and expensive; also, it requires well prepared rock cores. Therefore, indirect tests are often used to predict the UCS, such as Schmidt hammer, point load index and sound velocity. Besides, these indirect tests ca...

Sediment transport rates are a function of flow hydraulics, bed composition, and upstream sediment supply. Open-channel flow problems are relatively more difficult to solve than those of closed-conduit because the shape and size of a natural channel vary in a wide range from rivulets to large rivers. While the artificial (manmade) channel has a regular geometric shape, the cross-sectional shape of natural channels may be very irregular. In a movable boundary channel the cross section undergoes deformation due to s...

The truck and shovel transportation system is the most important part of the open pit mining operation because a considerable amount of the total mining costs is related to it. Reducing the transportation cost has a great impact on reduction of the total cost. One method to reduce the cost per ton in transportation systems is the optimization of the truck–shovel assignment. In this paper, software has been developed for optimal assignment of N trucks to M shovels with different grades of the minerals, based on m...

Slope failure occurring at projected slope operations at open pit mines can lead the workers safety to dangerous positions. In some cases the rock disturbances which may be thought about that, they lead slope failures around the open pit mine operation develop physiological problems among the mine workers. The main aim of this work to determine if the conditions of critical slopes in open pit mines can be monitored through the electrical resistivity methods. The depths of sliding at selected slope were analyzed by...

The world is being polluted rapidly in recent years. Pollution, which can stem from both natural and artificial causes, has a detrimental effect on our health and the environment. People’s contribution to the pollution cannot be emphasized enough. Technological development also plays an important role in environmental pollution. Extravagant uses of technology and people’s lack of sensitivity to the damages of technology cause pollution to increase in an uncontrollable rate. Pollution causes both global warming...

This work began with the hypothesis that buildings are designed and built to enhance the quality of our life. Many buildings fail to perform adequately and cause illness and productivity losses to the occupants.
