Since early times the civilization used to record and store their information about accumulated knowledge, everyday life necessities and other important things. Starting with clay tablets, stones and paper as a more advanced technology followed. Since that moment this trend made its way through centuries until nowadays, with new technological capabilities resulting in the form of digitalization. The paper discusses nuances of the terms, such as digitization, digitalization and digital transformation in scientific ...

In Kazakhstan, the main porphyry copper deposits are located in the Northern Balkhash region. The Konyrat, Aktogay, Aidarly, and Borly copper-porphyry deposits have been explored and exploited in this area. The main reserves of the country's copper raw materials are associated with these deposits. The Eastern Balkhash region is part of the North Balkhash ore zone. Previous studies on the Eastern Balkhash region focused on the Aktogay region and did not pay due attention to the southern part of the East Balkhash re...

Nature-based Solutions represent a set of powerful tools that are intended to reconcile often conflicting economic and nature conservation goals. Rapid infrastructure development threatens biodiversity globally. In this context application of Biodiversity Net Gain strategies start to gain traction. One possible approach to achieve the Net Gain outcomes is to apply Nature-based Solutions. It is, however, important to understand that application of the solutions does not guarantee biodiversity outcomes that could co...

In this regard a lot of debates have primarily started on a scientific level with the goal of finding the best strategies for trying to solve complex creat...

The European Green Pact launched a concerted strategy for a "circular", climate-neutral, resource-efficient, and resource-efficient economy. Yet globally, only about 20% of textiles are collected separately from the rest of the waste, with a truckload of textiles sent to incineration or landfill every second, and less than 1% of all textiles in the world are recycled into new textiles. In this context, the environmental impact (air, soil, water) due to the landfilling of these textile wastes is huge. In this regar...

Soil contamination near waste dumps is a complex problem, landfills are major contributors to environmental pollution, causing continuous degradation of land surfaces and significant environmental consequences. The challenge in question is to combat soil degradation and heavy metal pollution by implementing targeted soil protection measures and policies. Soil pollution disrupts the delicate balance of nutrients within the soil. This study focuses on assessing the impact of heavy metals by collecting soil samples i...

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...

In this work, I used the data from the geophysics portal of the Geological Institute of Romania (maps, sections), field measurements as well as the WGM 2012 model from the International Gravimetric Bureau. The measurements carried out in the south of the Southern Carpathians were represented by magnetometric measurements. Corroboration of geophysical information with geological and tectonic ones led to the confirmation of deep structures. The geological sources, which give geophysical samples specific to each geop...

Annually, a city with 500,000 inhabitants generates approximately 115.5 million cubic meters of wastewater. The treatment of this wastewater is efficiently managed using activated sludge, which comprises a diverse community of protozoa, infusoria, lower crustaceans, algae, and microorganisms. These organisms facilitate the effective treatment of large volumes of wastewater in treatment plants. However, the activated sludge proliferates by consuming organic materials in the wastewater, resulting in the accumulation...

Rapid urbanization increases the vulnerability of cities to natural hazards, especially earthquakes, as unplanned growth can aggravate structural risks and strain infrastructure. This research is based on a project -Automatic urbanization monitoring for risk assessment by remote sensing and Copernicus data- which aims to improve the detection of urban growth patterns and identify areas with increased seismic vulnerability. This project-s main goal is to develop and test a prototype for automatic urbanization monit...

Hydrogen combustion is presented as a potential solution to cover the heat demand with renewable energies. However, current technologies do not allow the combustion of pure hydrogen and it must often be mixed with fossil fuels. Carbon dioxide (CO2) has proven to be useful for stabilizing hydrogen combustion, as has methane (CH4). Therefore, this research proposes the use of biogas as a stabilizer of pure hydrogen combustion. For this purpose, experimental tests were carried out, burning a lean biogas (BG 50% CH4) ...

The aim of the paper is to highlight the potential of old mining regions for the development of geotourism. The region of Central Spis was known for its long-standing mining and industrial activity. In the 1990s, a decline regime began, mining activities gradually ceased and the mines were closed. The region subsequently experienced an economic and social decline. The mining areas, mining buildings and facilities have been preserved in the individual villages. Mining landforms are also preserved, both on the surfa...

The River Chorokhi delta is located in the southeastern part of the Black Sea, including Batumi city with its coastal part, which today is heavily washed away. Until the 90s of the 20th century, its litho- and morphodynamic peculiarities were mainly conditioned by the solid runoff of the Chorokhi River. Before the construction of dams in Turkey, its volume was 2.5 million m?/per year. In the last 25 years, due to the dams built in Turkey, solid runoff has been catastrophically reduced by 60 times. Also important w...

Accidental explosions and fires caused by combustible dust are some of the most significant threats in many industries where layers of combustible dust and clouds are formed as a result of technological processes. Combustible powders react with air oxygen in a process known as oxidation, which produces carbon dioxide, carbon oxide, water, and other gases whose contents depend on the temperature at which the oxidation occurs. The dust cloud is the main form of existence of combustible dust in the production area an...

The explosive atmosphere may be caused by flammable gases, vapors, or combustible dust. In the event that the material is combined with air in an adequate proportion, an ignition source is required to produce an explosion. Fuels and other liquids, as well as solvents from industrial items, release volatile vapors that can catch fire or explode when they come into contact with the air. At normal temperatures, flammable liquids can emit enough vapor to form combustible mixtures with air, heat, and often thick, black...

Coal mine spoil heaps are subject to reclamation processes in order to restore their environmental, social and economic functions. The reclamation may consist of placing soil layers (topsoil, TS) on the surface of the bare rock (carboniferous rock accompanying the coal seam) and then planting vegetation. However, waste rock (bare rock, BR) is usually left in place without overburden due to high costs. In both cases, there is a spontaneous succession of consisting vegetation of native and alien species. In this stu...

Nowadays, tourism represents a kind of environmental consumption, and tourists account for a significant proportion of consumption. Tourists therefore play an important role in developing or negatively affecting sustainable tourism. Eco-friendly accommodation, designed to reduce the negative environmental impacts of tourism become increasingly popular worldwide. Although the popularity of eco-friendly hotels has increased, the actual stays in such hotels are relatively short. The impacts of the tourism system on n...
