The inductively coupled plasma optical emission spectrometry (ICP-OES) is recognized as a robust method for the determination of different elements in liquid and solid samples. However, for metals determinations from solid samples, digestion is required in order to dissolve the analytes into liquid solution. It was the aim of this paper to validate the ICP-OES method for determination of metals from zeolite samples after acid digestion. The suitability of three digestion procedures using wet digestion with mineral...

The cause of the explosion is the thermal energy delivered by the flammable/ fuel ignition source. The action of the ignition source on the flammable medium can be direct or indirect. The most common of the direct sources of ignition are open flames and electric and mechanical sparks. These sources release their energy into the environment, which, if it contains flammable substances in appropriate proportions, is initiated. This is followed by a chain of fuel oxidation reactions and by the propagation of a flame f...

Water in general and especially drinking water, is becoming an increasingly scarce commodity in the Central Europe region due to the climate change. For a human, water is a bare necessity of life. The necessary amount of water to maintain human life is several litres a day. However, in a modern way of life, daily water consumption is usually over 100 litres. This amount accounts only for the personal consumption. To ensure the operation of national economy, consumption must be much higher. There are two ways how t...

The deformation process developing in the rock mass causes an increase in strains that may result in rockbursts. In this paper the data obtained by the PSInSAR technique covering the northeastern part of the Upper Silesian Coal Basin were used. The aim of this pap...

ANALYSIS OF THE DYNAMIC INTERACTION OF AN AGRICULTURAL MACHINE WITH THE ENVIRONMENT

(STEF92 Technology, 2018-06-20, Alina Ovanisof)

Show more

Using vibration processing techniques in tilling is convenient due to design simplicity of the involved devices, as well as to efficiency reasons, such as soil compaction reduction. However, depending on the design of the agricultural machine and on the working regime, such methods can affect the environment, the comfort of the human operator and even his health. The paper studies some effects of the vibrations of an agricultural machine with an eccentric rotating mass, transmitted to the soil and to the human ope...

ANALYSIS OF THE POSSIBILITY OF SELECTING GREEN FACADES IN THE DECISION MAKING PROCESS

(STEF92 Technology, 2018-06-20, Michał Juszczyk)

Show more

Fa?ade, as an external finishing of a building, gives the building its original character, obtained due to the choice from variety of forms and freedom in shaping. The decision to use a particular fa?ade system depends on the type of the object, the investor's requirements and financial possibilities, and the designer's creativity. This paper?s aim is to present the procedure of analysis that leads to a choice of the fa fa?ade system for a public building, including criteria such as: cost, technical parameters, ae...

ANALYSIS OF THE PRESENT AND NEAR FUTURE WIND CONDITIONS IN THE WESTERN SIDE OF THE BLACK SEA

(STEF92 Technology, 2018-06-20, Daniel Ganea)

Show more

The aim of the presented paper is to analyze the 10-meter wind (U10) conditions of the western part of the Black Sea during the present and near future interval. More precisely, 10 locations were studied. Regarding the geographical location, the points of interest are located in the range 40oN to 47oN and 27oE to 34oE as follows: 2 points are near to the Ukraine?s coast line, 3 to Romania?s coast line, 2 to Bulgaria?s coast line and 3 to Turkey?s coast line. Thus, for analyzing the wind conditions during the prese...

ANALYSIS OF TREATMENT SCENARIOS FOR RECYCLING AND REUSING OF WASTEWATER

(STEF92 Technology, 2018-06-20, Elena-Adriana Jarcu)

Show more

Because of the limited resources of water and increasing demand for it, solutions for wastewater recycling and reuse have become of great interest. Wastewater can be recycled for the same purpose or can be reused for other purpose, but first it must to be treated. In this paper some scenarios of using Sequential Batch Reactors treatment of wastewater were investigated with the purpose of reusing or recycling in small-sized residences like chalets or guest houses. Simulations were done using BioWin, which is a powe...

ANCIENT MIDDLE-CARBONIFEROUS FLORA OF THE ORULGAN RANGE (NORTHERN VERKHOYANSK) AND JUSTIFICATION OF AGE BYLYKAT FORMATION

(STEF92 Technology, 2018-06-20, A. N. Kilyasov)

Show more

The most ancient Late Paleozoic flora of the Verkhoyansk is known only on the western slope of the Orulgan Range, where relatively abundant complex of the Early-Middle Carboniferous vegetative remains was identified in the Bylykat Formation by N.A. Shvedov in sixties of the last century. The Bylykat Formation was defined as the lowest stratigraphic unit of the Verkhoyansk terrigenous complex, exposed in the core of the Orulgan anticlinorium [8]. Volume, division into subformations and stage belonging of this predo...
