THE PCA OF PHYTOMINING: PRINCIPLES, CHALLENGES AND ADVANCES

There is a number of commercially valuable elements whose concentration in the crust of the earth is too low for an economic mining with traditional approaches. However, phytotechnologies which take advantage of the capacity of certain plant species to take up these elements from the soil solution and accumulate them to large amounts in their biomass can be used for an economic winning of various metals and metalloids. This specific use of phytoextraction which has already been as one technology in the phytoremediation of contaminated sites is called “phytomining”

STUDYING THE POSSIBILITY OF USING RED-BROWN CLAY FOR RECLAMATION OF COAL WASTE DUMPS

The coal mining industry, as the source of the main fuel resource and the main energy resource, has particular importance for Ukraine. The largest coal regions of Ukraine include Donetsk, Lviv-Volynskyi and Dnipropetrovsk brown coal ponds. Their total area is 3% of the total area of Ukraine

BIOAVAILABILITY OF ELEMENTS FOR EFFECTIVE PHYTOREMEDIATION AND PHYTOMINING: THE ROLE OF RHIZOSPHERE PROCESSES

The success of phytoremediation (especially phytoextraction) and phytomining depends heavily on the bioavailability of target elements, which, among others, is a function of soil mineral phases, soil organic matter, pH and redox potential. The use of soil additives which, e.g., change soil pH or increase the amount of chelating compounds, has been propagated in the past in order to desorb the target elements from the soil matrix. These additives, however, may have negative environmental consequences by causing leaching of toxic elements from the soil due to enhanced mobility in the soil solution. For this reason less dangerous alternatives are necessary which use the natural capacity of plants to increase availability of target elements in their root environment

SHORT-TERM EFFECT OF DISPERSION OF RESIDUAL SLUDGE ON THE SOIL EUCALYPTUS CAMALDULENSIS DEHNH, TIARET (ALGERIA)

Silvicultural upgrading of sewage sludge is an alternative to current solutions. It presents a lower risk of contamination of the human food chain than its use in agriculture. In this context, the use of forest plantations can offer many advantages

Ecomining as a pattern of integrated approach towards sustainable mining

This paper briefly describes the Educational Project “EcoMining: Development of Integrated PhD Program for Sustainable Mining & Environmental Activities” (2019–2022), which is being implemented between Dnipro University of Technology (DUT, Ukraine) and Technical University Bergakademie Freiberg (TU BAF, Germany) under support of German Academic Exchange Service (DAAD)

Fine-scale vertical position as an indicator of vegetation in alkaligrasslands – Case study based on remotely sensed data

tVertical position is an important driver of vegetation zonation at multiple scales, via determining abioticenvironmental parameters, such as climate, soil properties and water balance. In inland alkali landscapes,elevation is a key factor for understanding patterns of salt accumulation and water table which is thereforeconsidered a good indicator of alkali vegetation types. Remote sensing techniques offer viable solutionsfor linking elevation data to vegetation patterns by providing an elevation model of extended areas.Our goal was to test the relationships between fine-scale differences in vertical position and vegetationpatterns in inland alkali landscapes by vegetation data collected in the field and elevation data generatedusing airborne laser scanning (ALS). We studied whether vertical position influences vegetation patternsat the level of main vegetation groups (based on alliances) or even at the level of associations. Our studysites were situated in a lowland alkali landscape in Hortobágy National Park (East-Hungary). We groupedthe associations into four main vegetation groups: loess grasslands, alkali steppes, open alkali swards andalkali meadows. Even though we detected a very limited range (121 cm) in the vertical position of the mainvegetation groups, they were well separated by their vertical positions. At the level of associations, a moredetailed elevation-based distinction was also possible in many cases. The revealed elevation–vegetationcorrelations show that high-resolution mapping based on ALS remote sensing techniques is an idealsolution in complex lowland areas, such as alkali landscapes. Our findings suggest that in other typesof lowland landscapes, characterised by elevation differences, the applied method might hold a greatpotential as a supporting tool for vegetation mapping

BGSU University Admissions System: Campus Training Module

The purpose of this project was to create an online training module to acquaint faculty and staff at Bowling Green State University with the University Admissions System and provide them with an overview of the functionality and resources available to them for their recruitment needs. Delivered through the Canvas environment, the course offers flexibility in content delivery through a variety of methods including documents, videos, quizzes and encouragement of self-exploration, in an attempt to accommodate a myriad of learning styles. Upon completion of each section, users should feel empowered to navigate UAS and utilize the data to drive their recruitment goals and initiatives. Subject matter experts, from the BGSU Office of Admissions, were asked to review the content and appropriateness of the course in relation to the project’s objectives. The overall response was positive and reassuring of the training’s fulfillment of those goals. This feedback supports the plan to allow new UAS users to enroll in the course as they gain access to the system and to prioritize the upkeep of the content as UAS expands and additional departments rely on its resources. Recommendations included additional areas for course content development and a frequently asked questions section for general inquiries most commonly posed by departments around campus

The Preeminent Biblical Role of the Father: A Qualitative Action Research Project

Fathers have a biblical role to teach their children commandments, statutes, judgments, and God\u27s Law. The father\u27s duty to teach his children should be handed down from generation to generation. The assumption is that fathers do not teach their children as God commanded. When fathers do not teach their children, they risk becoming an absentee father which leads to fatherlessness, ultimately ending in a broken home. To address this issue and offset this risk, a qualitative action research project was conducted. This intervention implemented two small group training sessions for fathers with children ages six and under. The sessions were applied in two six-week courses. Using a triangulation method, data was collected in six questionnaires, two surveys, and two interviews. A follow-up interview was completed one month after the course. Questionnaires discovered who, what, when, where, why, and how fathers taught. Surveys gathered background information on each participant\u27s spiritual formation status. The triangulation method cross-checked and confirmed that prior to the course, fathers had not taught their children. The purpose educated fathers in their preeminent biblical role to teach their children God\u27s Law. The goal for teaching fathers their role, duty, and responsibility helped them avoid the pitfalls of becoming an absentee father, fatherlessness, and a broken home. In fulfilling the thesis, children gained in spiritual formation, fathers became more spiritually mature, and families were strengthened in God\u27s Law. This project is duplicable. Other churches or groups can follow this model to strengthen families in Christ
