A camera attached to the erosion bridge is important, which is used to take photographs ...

Currently, the most advanced countries in terms of green thinking and production are Scandinavia, Switzerland, the Netherlands, Australia and New Zealand. The Baltic States also have adopted a joint Climate Declaration with a commitment to climate neutrality. The global production and consumption of plastics have doubled over the last two decades, yet only approximately 30% of plastic waste is recycled and reused, while the rest ends up in the environment. We all must play a role in protecting the environment at h...

The effect of pressurized hydrogen on pipeline walls is an important phenomenon that can cause damage to the integrity of the pipeline structure during transport and storage of gases. Hydrogen can penetrate the wall of metallic pipelines (alloy steel or carbon steel) and cause cracking or rupture of the material, which can lead to pressure loss or even serious effects (explosions, fires). The embrittlement of the metal by hydrogen is a phenomenon of degradation of the mechanical properties of the metal, as a resul...

The wealth of the bowels of Kazakhstan has not yet been exhausted, there are promising areas that are currently insufficiently studied, especially at depth. The reason for the insufficient knowledge of geological structures in depth is the lack of a theoretical basis for geological research and justification for the forecast of prospect for minerals. In this regard, geology faces the question of creating a scientific approach for predicting new prospect areas, especially at depth. Our analysis shows that the princ...

A type of protection represents specific measures applied to equipment to avoid ignition of a surrounding explosive atmosphere. Flameproof enclosure -d- consists in placing the parts that could ignite an explosive atmosphere inside of an enclosure that can withstand the pressure developed during an internal explosion of an explosive mixture and which prevents the explosion transmission to the explosive atmosphere surrounding the enclosure. Increased safety -e- represents a type of protection that consists in apply...

Blasting and mechanical excavation systems are the main methods used in the excavation of rocks masses in mining and construction works. Mechanical excavation is insufficient in the case of very hard rocks masses. Therefore, blasting is widely preferred for the excavation of hard rock masses. Environmental parameters such as ground vibrations, air-shock and fly-rock occur due to blasting. The magnitude of these parameters depend on the explosive per delay, distance between the measurement- and blasting points, geo...

Natural zeolites, a family of hydrated aluminosilicates, are important raw materials for micro and nano technologies due to their molecular-sieve, ion-exchange and catalytic properties. Their porous crystalline framework is built from alternating SiO4 and AlO4 - tetrahedra forming cages and channels, and improvement of zeolite performance is possible by thermal and chemical treatment. The influence of hydrochloric acid and calcination on heulandite-containing tuff from the Georgian Dzegvi-Tedzami deposit was studi...

A common practice under modern conditions in urban planning is the tendency of urban areas to grow, which is usually at the expense of agricultural areas. This, both in a global aspect and specifically for Bulgaria, is a particularly relevant problem due to the extremely important ecosystem functions of soil resources and the fact that they are an extremely slowly renewable natural resource. The assessment of ecosystems condition and their services is a suitable approach as an additional study on the effects of ch...

n the EU's perspective, energy efficiency is one of the most effective ways to reduce energy consumption and contribute to the fight against climate change. Recent studies have shown that energy efficiency alone is not sufficient to achieve sustainable development goals. The real challenge is to combine energy efficiency with energy sobriety. This work aims at raising a debate about the relationship between energy efficiency and energy sobriety and at studying how the principle of sobriety works. In particular, th...

It is known that since the signing of the Amazon Coop...

A genuine and urgent need is to prevent and treat bacterial diseases primarily caused by germs that have developed antibiotic resistance. These factors led to several studies focusing on alternate or supplementary antimicrobial methods. With the expectation that, unlike antibiotics, they will be effective without causing resistance, researchers are becoming increasingly interested in antimicrobial substances made from natural resources, such as plant extracts, essential oils, and peptides. The present study invest...

Firstly, this paper is focused on the analysis of runoff and erosion conditions in the chosen locality, which is in the South Moravian Region of the Czech Republic. The analysis was made using geographic information systems, mainly the ArcGIS Pro software program. Water erosion endangers more than fifty percent of arable land in the Czech Republic. Unfortunately, there is no systematic protection of the majority of soil erosion-threatened areas that would prevent further losses. One of the main causes of this is t...
