A simulation of the impact of waste batteries on ecosystem reliability
(AGH University of Science and Technology Press, 2020) Petrov, Oleksandr; Pogrebennik, Volodimir Dmitrovič; Šibanova, Alla Mikolaïvna; Ruda, Marìâ Vìtalìïvna
In order to assess the impact of a battery's multi-element composition on the state of the environment, a new approach is proposed through the determination of the reliability of ecosystems, one which makes it possible to obtain quantitative indexes of the stability and losses of natural ecosystems. These data can be used as indicators of the state of the environment, and hence as the assessment of an environmental component important for determining the actual impact of the multi-element composition of batteries. On the basis of such indicators, which can be obtained using the SimaPro software, it is possible to calculate thresholds beyond which negative phenomena occur, as well as to predict and simulate situations, to carry out the mapping of sources of risks, and to monitor changes. This will allow the causes of these changes to be identified or to determine the factors that slow down or retard the approach of ecosystems to a critical state, i.e. to develop preventive measures to avoid disasters. The eco-indicator 99 is one such method that allows us to accept a single estimate for a whole product - the so-called ecological index. It is the sum of all individual eco-points or partial indexes for all life-cycle processes. The computational procedure is carried out by summing up the results of weighing the phases of the life cycle.

Amber cockroaches, wood decomposers, dinosaur dung, clean Mesozoic ground and eusociality
(Wydawnictwa AGH, 2014) Vršanský, Peter
Among unresolved enigmas of ancient terrestrial ecosystems functioning, the origin of social life, wood decomposition, provisioning of dinosaur dung and cleanness of Mesozoic ground belong to most important ones (Zherikhin 2002).

Blattaria assemblage from J/K sediments of Chernovskie Kopi in Transbaikalian Russia
(Wydawnictwa AGH, 2014) Barna, Peter
The J/K fossil site Chernovskie Kopi in Transbaikalian Siberia (Russia) yielded insect fossils of 15 orders (Vassilenko 2005), descendants of the order Blattaria - the earliest termites (Vršansky & Aristov 2014), and insect trace-fossils (Sukatcheva & Vassilenko, 2011).

Logistics costs in the waste disposal system on the example of a steel mill
(AGH University of Science and Technology Press, 2011) Zwolińska, Bożena; Michlowicz, Edward
An industrial waste management system is a set of processes enabling space-time transformations along with quantity and quality changes aiming at the reduction of negative influence of the industry on the ecosystem. One of the ways of controlling the destructive impact of waste on the environment is recycling. There is no type of residue that cannot be reutilized having suitable technologies and financial resources. An important part of a company's development strategy is the profit and expenditure account. This article presents the overall costs generated within the waste management system of a full production cycle steel mill. The costs have been grouped by objects according to the criteria of main logistics processes realized within the waste management system.

Weathering of siderite in the polar conditions
(Wydawnictwa AGH, 2014) Figura, Paulina; Manecki, Maciej; Rzepa, Grzegorz
Rapid retreat and thinning of glaciers perturb balance of polar ecosystems. These processes influence global climate (Anderson et al. 2000, Płonka 2009).
