Cement is a silicone-based hydraulic binder, obtained by fine grinding of its components: clinker, limestone, gypsum, blast furnace slag, possibly grinding additives, but also other components such as kiln dust (CKD). The clinker is the most important component of cement, which is a granular material obtained by burning a powdery mixture of limestone and clay, with possible correction additives, in a furnace at 1450oC. The milling of clinker and other cement components is accomplished by means of ball mills with t...

The documents of the general cadastre may result from the centralized and selective take over of the data and all the cadastral records from the specialized cadastre, regarding the immovable assets that are their object of activity. These selectively taken elements use to update the general cadastre after the end of its introduction into an administrative territory. One of the main steps for completing the general cadastre is the realization of the real estate cadastre. This article presents the way in which the d...

The paper presents a study on water quality, which can be influenced by biological, physical and chemical parameters of water. Water quality has the purpose of identifying the direction of water use for both domestic and industrial purposes and is of particular importance to humans and living organisms. In addition to the human factors that have a major impact on water quality (both for surface and for groundwater), there are also natural factors and anthropogenic activities. The purpose of the study is to analyze...

In recent years we have observed a rapid increase in the demand for rare earth elements (REEs), related to industry intensive development in the field of new technologies. The biggest producer of REEs is China, which provides global markets with more than 83% of the whole amount of rare earth elements. It is worth mentioning that China has access to rich deposits of REEs, accounting for ca 37% of these metals resources available all over the world. For this reason, alternative possibilities to obtain rare earth el...

[1] Starting from the fact that the activity in the area of ?icleni - Romania is an activity of exploiting petroleum products, which ...

In the last decades, transport and handling equipment sites have became progressively pronounced in areas that were recently lacking transport services. In many cases, transport services are not provided in mountain areas and in areas that have not been significantly affected by anthropogenic impacts yet. Local natural materials and asphalt mixtures are used for road construction, in which it causes road movement. Used asphalt mixtures are made up of mixtures of various organic substances, usually aromatic nature,...

The research aim is to identify the effect of a surface forest fire on the productivity and viability of Scots pine (Pinus sylvestris L.) in a 23-year-old stand.

There is environmental quality as a one of the factors determining the quality of life in EU countries. EU countries use a combination of different tools of economic policy to ensure environmental (as well as economic) quality. However, environmental protection cannot be implemented without financial support. The most important tools of economic policy, already traditional used, are economic tools, which could improve the quality of the environment and quality of life. Environmental protection has become a part of...

Nowadays, protection of any sensitive electric equipment against any type of overvoltage (including lightning applied on power networks) is a big challenge for the power electronics domain. The most advanced and reliable devices used in order to perform this operation are metal oxide varistor based surge-arresters. These polycrystalline ceramic varistors are made of a mixture of different metal oxides, where the main ingredient (more than 80-90% as mass concentration) is the ZnO. The real improvements of these dev...

The paper examines the exposure of mountain creeks towards illegal waste disposal practices related to the lack of waste collection services in rural areas of Romania prior to EU accession and the low waste collection efficiency following the closure of rural wild dumps in 2009-2010. The paper estimates the amounts of household waste uncollected and disposed in selected small Carpathian rivers in the North-East development region. The expansion of built-up areas along the water courses leads to waste dumping pract...

Occupational health and safety is an important work discipline that must be included in the working life. Especially, developed countries have been able to place this discipline in working life, while developing countries have still problems. These problems take place both in terms of legislation and practice. The situation is similar to that of developing countries, in Turkey. The construction sector is in line with the development status of a country. The construction sector contributes both directly and indirec...

The paper highlights the necessity to implement a system for collection and storage of meteoric waters from the households in populated centers. For the proper functioning and operation of the sewerage system, the regional water - channel operator requires that the meteoric waters from each property should be solved separately. The solution adopted for meteoric waters consists in their use inside the household or their infiltration into the soil. The rainwater from the roofs of the buildings and from the yards wil...

The worlwide ascending demographic development automatically determined a growing demand of meat and other derived products from animals raised in livestock farms. Therefore, taking into consideration the fact that, every year, the need for animals food has increased, every compound feed factory (CFF) aims to obtain diversified formulas of final products, depending on the breed and the age of the animals that will be fed. To resist on the competitive market with this profile of production, all compound feeds facto...

This paper addresses an analysis on atmospheric pollution done by road vehicles. The substance emitted by vehicles that are present in the air, depending on their quantity and concentration, affects our health, generates discomfort and alters the environment. Global warming, or the greenhouse effect, since a certain period of time, is increasing from year to year. The recent increasing in registrations of vehicles which work on conventional fuels from the past few years (diesel oil, petrol) have led to a worrisome...

From a structural optimization point of view, the design of steel lattice towers begins with choosing from various alternatives to develop the geometry of the incorporated trusses. The biggest challenge is to find optimal geometry based on experience. In contrast to some structures that are generally intuitive to construct, (e.g. common buildings structures), the same design for the tower structures is frequently built for several times. Thus, cost savings and performance improvements obtained by structural optimi...

Segmentation of badly structured images is a complex task for different models of artificial intelligence systems. The given work presents algorithmic solutions for intercellular relations measurement in peripheral blood. There has been proposed hybrid algorithm, allowing to distinguish three classes of formed elements: ?erythrocyte?, ?leukocyte? and ?not erythrocyte and not leukocyte?. The algorithm provides for two-level processing of the image. Analysis of geometric attributes of image segments and their colour...

Autostereoscopy is a method for effective visualization of three-dimensional models with the help of ordinary imaging techniques. It allows achieving the 3D object observation without the need for special goggles, displays or other equipment. The Method itself is using rapidly alternating images of given object taken from defined angles, mimicking the position of the human eyes. Such animation induces a sense of depth. Autostereoscopy can be applied to a static image or even dynamic video materials. Firstly, we ha...
