Blasting operations associated with in-pit ramp construction in open-pit mines generate gaseous emissions originating from both explosive detonation and diesel-powered drilling and loading equipment. The research object of this study is the ramp construction process in an operating open-pit quarry, and the objective is to comparatively evaluate gaseous emissions across alternative blasting scenarios to support emission-aware operational decision-making. Five realistic blasting scenarios are assessed using a combined methodology that integrates laboratory fume index data for ANFO, emulsion explosives, and dynamite with diesel-emission estimates derived from non-road mobile machinery inventory factors. Laboratory detonation tests provide standardized upper-bound emission potentials for COx and NOx, while drilling and loading emissions are quantified using a fuel-based inventory approach. The results show that the dominant contribution to total mass emissions arises from diesel combustion during drilling and loading, consistent with studies on real-world non-road mobile machinery inventory factors. Detonation fumes, although chemically concentrated and relevant for short-term exposure risk, represent a smaller share of the mass-based emission budget. Among the explosive types, bulk emulsions consistently exhibit lower toxic-gas emission indices than ANFO, attributable to their more uniform microstructure and a moderated reaction temperature. Dynamite demonstrates the lowest fume potential but is operationally less scalable for large open-pit patterns due to manual loading. Uncertainty analysis indicates that both laboratory-derived fume indices and diesel emission factors introduce systematic variability: laboratory tests tend to overestimate detonation fumes, while inventory-based diesel estimates may underestimate real-world NOx and particulate emissions. Notwithstanding these limitations, the scenario-based framework developed here provides a robust basis for comparative evaluation of blasting strategies during ramp construction. The findings support increased use of emulsion explosives and emphasize the importance of moisture management, field-integrated gas monitoring, and improved characterization of diesel-equipment duty cycles.

Odour emissions from wastewater infrastructure represent a significant environmental and social challenge in urban areas. This study evaluates the odour impact of a municipal wastewater pumping station using an integrated field-based approach that combines sensory observations, chemical measurements and meteorological data. Field olfactometry and on-site gas monitoring were applied over a two-year campaign covering different operational and seasonal conditions. The results indicate that odour perception is strongly influenced by hydrogen sulphide concentration, air temperature and wind speed, with short-term high-intensity episodes playing a disproportionate role in odour nuisance. To support integrated interpretation, a Synthetic Odour Index (SOI) was developed to consolidate chemical, sensory and microclimatic information into a single numerical indicator, extending existing odour indices by explicitly integrating field-based sensory and meteorological data. The SOI showed a moderate but statistically significant association with odour intensity (r ≈ 0.3) and effectively differentiated low- and high-nuisance conditions. The proposed methodology demonstrates the value of combining field measurements with integrated data analysis for assessing and managing odour emissions from urban wastewater pumping stations and provides a practical basis for operational monitoring and odour mitigation strategies.

This article aims to analyze the positioning of contemporary jewelry production in two main aspects: design, and art; each with its own qualities and peculiarities. In other words, what is attempted is to find the place occupied by the production of jewelry nowadays, between design, (since it uses a design approach, and aims to serve a consumer market), and art, (since it is directly related to artistic practice, as it allows freedom of elaboration and confection by its creator). Thus, it is considered to analyze contemporary jewelry, pointing out points of convergence and divergence between design practice and artistic production, in search of a product that satisfies its user, meeting both their needs and their desires.

In the examinations of the Program for International Student Assessment (Pisa), there are questions that assess the student's ability to estimate areas of a region of the plane, where the boundary is not given only by straight line segments, using the information contained in a map. Motivated by these problems, we present a didactic sequence to introduce, in High School, rudimentary notions of the Integral Calculus, with the aid of the software of dynamic geometry GeoGebra, so that we can obtain the estimates. We also show that through the knowledge about integration processes, students of the last stage of Basic Education can develop some specific skills and abilities of Mathematics and its technologies described in the National Curricular Common Base (BNCC).

In the Polish sector of the Magura Nappe, along the front of the Pieniny Klippen Belt, strongly tectonized calcareous flysch up to 1000 m thick is exposed. Previously these deposits, composed of thin- to thick-bedded flysch, with a packet of Łącko-type marls, have been included into several Paleocene/Eocene formations, e.g., the Szczawnica Formation. This formation contains a poor assemblage of agglutinated foraminifera and a relatively rich assemblage of calcareous nannoplankton, with abundant reworked species. The youngest species give evidence of the NN2 Zone (Lower Miocene). Additionally, in three profiles (Szlachtowa, Knurow and Waksmund) of the Kremna Fm., Early Miocene foraminifera have been recognized. This research documented that during the Burdigalian, at the front of Central Western Carpathians, there still existed a residual marine basin probably up to 100 km wide. These deposits also contain thick packages of exotic carbonate conglomerates derived from the SE, previously regarded as the Jarmuta Formation.

Pytanie badawcze tekstu sprowadza się do rozważań nad możliwością aplikacji teorii postkolonialnych w przypadku postsowieckiej Gruzji. Krytyka postkolonialna niemal ominęła sferę postsowiecką, pozostawiając ogromną przestrzeń polityczną w monopolu idei interpretacji przez badania systemowo-tranzycyjne. Przez rozważania nad potencjalnymi limitacjami dla możliwości przepisania teorii w odmiennych uwarunkowaniach politycznych autor próbuje rozwinąć szerszą perspektywę dla interpretacji socjopolitycznych procesów w postsowieckiej Gruzji. Przypadek Gruzji jest interesujący dla teorii postkolonialnych, gdyż zgodnie z hipotezą Gruzja podlega dwoistości postkolonialnego doświadczenia. Z jednej strony podlega procesom dependencyjnym ze strony byłego hegemona, z drugiej w ten sam sposób (jako kolonialny dzierżawca przemocy) postrzegana jest przez mniejszości etniczne w „lokalnym” imperium. Zatem, używając nomenklatury postkolonialnej, tekst stara się zredefiniować transformacyjne i postkolonialne doświadczenie Gruzji.
