Although originally developed for military purposes, Global Navigation Satellite Systems have become indispensable for an ever-growing range of civil and scientific applications such as cartography, cadastral and land information systems, transport systems, precision agriculture, self-driving vehicles, rescue missions, etc. The accuracy of positioning by means of GNSS, however, is affected by atmospheric distortions of the GNSS signals as well as by the characteristics of the receiver (e.g. number of channels, fir...

A study was made of the influence of ZSM-5 zeolite on the composition and properties of the products of fast pyrolysis of flax shives in the temperature range of 350-750 -C. Zeolite ZSM-5 increased the heat of combustion of gaseous products, as well as the content of methane, ethylene, hydrogen, and carbon dioxide, which is probably associated with the processes of cracking of volatile products passing through a layer of a catalyst heated to high temperatures. The synthesis and study of zeolite catalysts ZSM-5 con...

The main idea of the article is to assess the landscape potential for the use of renewable energy systems based on systematic and landscape-ecological approaches. In general, these approaches consist of the analysis of the features of landscape components and their impact on the redistribution of energy flows in the landscape, which in turn form the potential of renewable energy resources of each specific landscape contour. A systematic approach is to consider the holistic properties of a particular landscape in t...

State activity, first and foremost, must be aimed at the land resources effective management and protection against the human economic acti...

The aim of the article was to assess the importance of Natura 2000 sites in halting land take, given that the European Commission has set itself the target of reducing land take in the EU to zero by 2050. In the surveyed area, land take is primarily a consequence of the economic activities carried out and of their pace and intensity; the density of housing also puts pressure on the phenomenon through the permanent expansion of the built-up area of the settlements (the brown belt), especially in the economically ef...

Nature-based Solutions is an umbrella concept, gaining traction in recent years. It implies working with nature in order to simultaneously address multiple challenges humanity faces today, including biodiversity loss, climate change, food and energy insecurity. Nature-based Solutions are being applied across landscape types, including urban, rural, forest and protected areas. Combining nature-based solutions with landscape design, however, has predominantly been considered in cities. However, there is a great pote...

Ochre samples from three abandoned Sb deposits were collected in three different seasons and were characterized from the mineralogical, geochemical, and microbiological point of view. They were formed mainly by poorly crystallized 2-line ferrihydrite, with the content of arsenic in samples ranging from 0.7 wt.% to 13 wt.% and content of antimony ran...

The European Union and its Member States have set themselves to achieve climate neutrality across the EU by 2050. The agricultural sector is one of the emitters of greenhouse gases (GHG). To achieve its climate neutrality goals of reducing the increase in global temperature to below 2-C and limiting it to 1.5-C, the EU has adopted the Green Deal and the Farm to Fork Strategy based on it. These goals create the need for the development and implementation of innovations. The agricultural sector will experience sever...

Fish oils with a high content of polyunsaturated fatty acids (PUFAs) are gaining increasing interest in the food and nutraceutical industry, due to their important functional properties for human beings- health improvement. The most important PUFAs have at least two double bonds placed on the carbon chain. These include ?-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahaxaneoic acid (DHA). Microencapsulation is a technique used to protect the bioactive compounds from oxidative damage, to ensure their ...

The production of oil and gas includes drilling a number of wells for exploration or production activities. During drilling operations, large volumes of drilling fluids are used to facilitate the process. In Libya, after completion of drilling operations drill cuttings and waste drilling fluids are typically discharged close to the oil fields without treatment. This can result in negative ecological impacts on the surrounding environment e.g. through infiltration of toxic constituents into soils and underground wa...

Currently, many emphases are placed on the possibility of limiting excavation works in the event of water pipelines or sewage systems failure. For this purpose, various types of inspection and repair robots/manipulators are used, which can enter the installation's interior without the need to get into the pipe physically (e.g. with an excavator). Mobile robots allow you to diagnose the problem (or provide information on which section the failure occurred) and in some cases, to repair (unplug) the installation with...

Biomass is monitored in many agricultural studies because it is closely related to the growth of the crop. The technique of digital repeat photography that continuously capture images of a given area with an RGB or near-infrared enabled cameras, Phenocams, has been used for more than a decade mainly to estimate phenology. Studies have found a relationship between Phenocam data and above-ground dry biomass. In this context we investigate the modeling of barley fresh above and underground biomass with Green chromati...

Teichi bog is largest intact moss bog in the Baltics states. The article considers the hydrological exchange process of the bog and surrounding areas. It plays an important role in the ecosystem, as well as a factor in stabilizing the water level, as bog peat in its natural state contains 88%-97% water. It belongs to raised bogs, since its upper layer is located above the surrounding relief. Replenishment of water resources in the Teichi Nature Reserve occurs mainly due to precipitation. In turn, the bog with surf...
