A potentially explosive atmosphere exists when a mixture of air, gases, vapours, mists or dust combines in a way that can ignite under certain operating conditions. Hydrogen is the special gas in this context. Those who have knowledge of the properties and flammability of hydrogen will recognize that hazards due to explosive atmospheres must be assessed more and more frequently as the element is utilized, and, if necessary, appropriate protective measures must be taken. In this kind of atmosphere, special attentio...

The removal and collection of dust particles from the air discharged into the atmosphere by industrial plants processing, transporting and storing dusty materials is an important objective for employers to prevent air pollution according to environmental legislation and employee safety regulations. Where the dust in question is flammable and may generate an explosive atmosphere, measures must be taken to prevent explosion and/or limit the effects of explosion. To this end, proper assessment of the risk of explosio...

The continuous development of human society from a technical-economic point of view is closely related to the increase in energy consumption. However, this implies the rapid depletion of existing fossil fuels and an accelerated increase in global pollution. At the moment, to counteract these impediments, one of the most important sources that can be used for the purpose of energy production, without having a negative impact on the environment, is hydrogen. Due to the fact that, when mixed with air, hydrogen can ge...

A significant seismic sequence started on 13 Feb. 2023 at 14:58 GMT with a mainshock of 5.2 ML located at 17 km depth and at 14 km distance NW from Targu Jiu city. The first shock was followed by 16 aftershocks with magnitudes between 2.1 and 3.4 after which a second mainshock of magnitude 5.7 was triggered next day, 14 Feb., at 13:16 GMT. The largest acceleration at the second shock (105.25 cm/s2) was recorded at Gura Zlata station as well. The seismic events hypocenters are established by several methods. First ...

Many processes involving dusts, suspended or accumulated, have the potential to lead to fire, explosion or decomposition in the presence of oxygen and an ignition source. The risk of dust explosions increases as more and more products take the form of dusts or require the use of dusts during manufacture. In spite of extensive research and development to prevent and mitigate dust explosions in the process industries, this phenomenon continues to represent a constant hazard to industries including manufacturing, usi...

Unfortunately, soil is a non-renewable resource that fulfills several vital functions such as food/biomass production, storage, filtration and transformation of mineral or biological substances, source of biodiversity and habitats, etc. Due to the development of industrial activities outside the localities, in many areas the soil is degraded. Among these degradation processes can be mentioned degradation of organic matter, contamination, soli salting, and erosion. This paper is dedicated to the presentation of the...

The Vrancea zone, located in Romania, at the sharp bend of the Southeastern Carpathians, is a well-defined seismic region in a continental convergence area with unique properties and generating the most destructive subcrustal earthquakes in Europe. The seismicity is concentrated in a confined, high-velocity, focal volume at 60–200 km depth range. The increasing number and quality of waveforms digitally recorded in the last time by the National Institute for Earth Physics (NIEP) provide the opportunity to better co...

The Bistrita River was the first river harnessed for hydropower purposes in Romania, starting with 1960. Currently, on this river, 29 hydropower plants with different capacities are functioning, producing about 10% of the entire Romanian electric energy from hydro. Many of them were realized in series, in cascade. In the present paper, the area of Pangarati, Vaduri, Batca Doamnei, and Reconstructia hydropower lakes was analyzed. Of these, three are Nature Reservations, Nature 2000, RAMSAR sites. The lakes being re...

The risk assessment of an organization is stipulated in international standards and in a variety of international and national laws and reglementations. In the context of the obvious environmental problems and incidents with disastrous effects for the environment of the past 50 years, industrial and business environment recognizes the importance of environmental risk management and its applied. In the process of the environmental risk management, the risk assessment and risk treatment plays a crucial role in the c...

The focal mechanism and rupture directivity for intermediate-depth earthquakes occurred in the Vrancea source (Romania) are determined using FMNEAR algorithm [1]. The method is based on the waveform inversion of near-source seismic waveforms and on a linear finite source model. When the FMNEAR algorithm is started the first parameters that are determined are the moment magnitude (Mw), the double couple focal mechanism (strike, dip, rake) and the distribution of seismic moment along strike. This provides a first or...

The emergence and development of the internal combustion engine began in the 18-th century in England. But the first patent for a piston engine with compression ignition was achieved by Rudolf Diesel in year 1892 [1]. The engine use coal powder as fuel. The most used vegetable oil as a fuel and peanut oil. In the year 1859 in Pennsylvania was first released at the amount of crude oil that has been refined for kerosene and gasoline. Because a large quantity of by-products remained unused, Rudolf Diesel using a frac...

This paper reports the preparation of novel polymer membranes by phase inversion at room temperature (25 пїЅC), using acrylonitrile, acrylic acid, dimethyl sulfoxide and small amount of medicinal plant extract. We investigated the structure of the resulting membranes through Fourier Transform Infrared (FT-IR) spectroscopy and SEM microscopy. Also was determined the water content. FTIR-ATR spectra show that the peak at 1723 cm-1 shifted to lower wave number when medicinal plant extract (1715 cm-1) is added in the p...
