Microbial immobilization is a promising strategy for various applications, including environmental remediation and bioprocess engineering. However, the efficacy of immobilization largely depends on the characteristics of the carriers. Biomass wastes are renewable and abundant resources that can be subjected to hydrothermal carbonization (HTC) for hydrochar production, a resulting carbonaceous material with a porous structure. This porous architecture offers extensive surface area and facilitates the colonization a...

This study aimed to investigate carbon storage dynamics in pure pine, oak, and mixed forests within a one-hectare area. Tree samples were collected to measure their weight, size, and density. Each type of forest was estimated how much carbon is hold per hectare. The findings revealed significant differences in carbon storage capacities among them. Pure oak forests emerged as the top carbon reservoirs, with 57% of their trees' mass comprising carbon. Pure pine forests followed closely with 51% carbon storage. Inter...

This paper presents a multidisciplinary approach to analyzing data from Telegram for early warning information regarding cyber threats. With the proliferation of hacktivist groups utilizing Telegram to disseminate information regarding future cyberattacks or to boast about successful ones, the need for effective data analysis methods is paramount. The primary challenge lies in the vast number of channels and the overwhelming volume of data, necessitating advanced techniques for discerning pertinent risks amidst th...

The geometric levelling of the highest order has been the main method for many scientific and engineering tasks for more than 150 years. One of them is the monitoring of the recent vertical movements of the Earth-s crust. In order to understand the low of accumulation of the discrepancies in levelling lines, many investigators have planned and performed various experiments and analysis through the years. As a result, the systematic effects of many sources of measurement errors have been studied, and partly or full...

Carbon emission has increasingly become a topic of the day. Carbothermic reduction processes and energy generating units have for years used generic carbonaceous materials contributing to high carbon pollution. Ongoing investigations are showing good prospects. This paper corroborates a comprehensive review on the potential of biochar as an innovative and sustainable alternative to traditional carbon sources in pyrometallurgical processes, addressing the environmental ithreats caused by fossil fuel use, such as gr...

Lava tubes are natural underground structures formed by volcanoes during magmatic eruption events. Their exploration has aroused undeniable interest in the scientific community because of their potential as future habitats capable of hosting human missions in the Solar System. Indeed, there are significant topographic features that indicate the existence of lava tubes on the Moon and Mars, offering natural shelter and environmental insulation for permanent planetary settlements. The article summarizes the geologic...

This paper presents the monitoring of an eroding phenomenon (gully) near Ciurila, Cluj County, Romania, using UAV (Unmanned Aerial Vehicle) and GNSS (Global Navigation Satellite System) technologies. In this sense, the monitoring results through sustainable and non-invasive technologies are presented, following four cycles of observations, carried out between June 2019 and April 2021. The paper aims to present the advantages and limitations of such a study, as well as the importance of monitoring erosion phenomena...

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 ...

The research uses monthly water flow in river watersheds within Danube-s river basin - Ogosta, Iskar, Yantra and Rusenski Lom rivers, as pilot basins. The water flow indicators describe river flow regime and hydrological streamflow characteristics. Our article describes the determination of environmental flow limits on surface water abstractions in Bulgaria. Monthly river flow is characterized by annual variability due to climate factors and anthropogenic impacts. Furthermore information from hydrometric stations ...
