“…For example, the European Union has called for the ratification and implementation of the "Best Available Techniques (BAT)" in industrial cement and lime production (Schorcht et al, 2013;Valderrama et al, 2012). The reference document proposes reduced fuel consumption, low organic raw materials selection, and the utilization of low carbon heating values to replace coal (Giner-Santonja et al, 2019;Schorcht et al, 2013). (Calvo et al, 2021).…”

This paper reviews the utilization of corn cobs ash (CCA) as pozzolanic, cementitious, and binary cementitious materials in concrete. CCA is the grey-to-brown, inorganic or heterogeneous residual material derived from the high- temperature incineration or combustion of corn cobs (CC). Despite the typical problematic nature of biomass ash, the chemical composition of CCA renders it a potential pozzolanic material. Therefore, numerous studies have critically examined the process technologies and operational conditions for CCA production and its application as a partial replacement for cement in concrete. Other studies have extensively characterized the physicochemical, morphological, microstructure, and thermal properties of CCA through various analytical techniques. Potential pozzolanic materials must meet the condition: SiO2 + Al2O3 + Fe2O3 ≥ 70%, according to ASTM C618, to which CCA complies satisfactorily. Hence, the use of CCA as a replacement for cement has been investigated over the years. Findings indicate that the partial replacement of cement with CCA decreases compressive strength, thermal conductivity, ultrasonic pulse velocity, and density of the hardened concrete at normal temperatures. Nevertheless, the thermal treatment (calcination) of CCA and extended curing enhances compressive strength owing to higher silica content and extended surface area. Besides, the partial replacement of cement with CCA enhances the insulation properties of mortar, which improves thermal comfort, costs and energy savings in buildings. Hence, the partial replacement of cement with CCA provides an environmentally friendly, low cost, and sustainable approach for valorizing CC residues whilst addressing CO2 emissions in construction.

“…A significant part of these papers addresses matters of sustainable environmental management and applications of modern pro-ecology technologies in technical engineering. For example, Ghimire and Kim [51] and Wang et al [52] raised the issue of using unconventional energy sources, while Giner-Santonja et al [53] studied pollution emissions to the air. The AHP method has also been used in studies concerning urban river systems [54], surface water quality assessment [55] and wastewater treatment plants [56].…”

Progressing urbanisation is one of the key causes of environmental degradation. This problem also applies to stormwater management. For this reason, drainage infrastructures should be designed in harmony with nature and the decision for selecting a specific stormwater management system solution must not be taken on an ad-hoc or single-perspective basis. The purpose of this paper is to identify the criteria for selecting the best solution for a problem involving the selection of a stormwater management system, and to present a method that will enable all relevant criteria to be taken into account in the decision-making process. The developed decision problem structure takes into account all criteria related to the construction and operation of stormwater infrastructure, and its individual elements were identified based on the analysis and synthesis of information regarding the principles of stormwater management in Poland. The presented approach will allow for the taking into account of all, often mutually exclusive, criteria determining the choice of the stormwater management system option. This, in turn, will make it possible to significantly simplify the decision-making process. The indicated criteria can form the basis for choosing the most favorable stormwater management system for both large urban catchments and individual facilities. Thanks to the considerable flexibility of the developed decision problem structure, its widespread application can contribute to improving the efficiency of stormwater management systems. An example of the developed model’s application in a decision-making process is presented, concerning the selection of a design variant of a single-family residential building’s stormwater management system in Poland. Four design variants were included in the analysis, and the Analytic Hierarchy Process was used as the tool to select the most favorable option. This study shows that nature-based solutions are the most beneficial decision stormwater management options.

“…The AHP method is a multi-criteria and multi-factor decision-making method that quantitatively analyzes qualitative problems. It can classify the various factors in the process of complex system problem processing in an orderly manner, and integrate the researcher's objective judgments with expert opinions, thereby achieving the importance analysis of elements through the pairwise comparison, and a wide range of applications in the engineering field [23][24][25][26]. The specific implementation steps are as follows.…”

The teacher-student (T-S) matching in colleges has not been studied in a thorough and systematic manner. It remains unclear how college T-S matching affects the knowledge innovation of graduate students. Therefore, this paper firstly analyzes the factors affecting the knowledge innovation of graduate students, and selects the T-S matching mode that promotes their knowledge innovation. Then, the promotion of knowledge innovation was investigated under the T-S matching. Finally, the authors quantified the importance of knowledge innovation among graduate students, and summarized the strategies and methods for cultivating innovation ability based on T-S matching. The research results provide a panoramic view of the cultivation of innovation ability among graduate students from the angle of T-S matching.
