The aim of the study was to compare the overall total phenolic compounds content and antioxidant properties of spices (oregano, thyme and rosemary) from ecological and conventional cultivation. The antioxidant activity of the obtained spice extracts was estimated with the use of radical tests (DPPH and ABTS), binding and reduction of metal ions, accelerated Rancimat test and based on the spectrophotometric method. The obtained results indicate that spice extracts from ecological cultivation are characterized by a higher, overall total phenolic compound content compared to spice extracts grown in a conventional system. Ecological spice extracts showed better antioxidant properties than conventional spices in most tests. The results of the statistical analysis show a positive correlation between the total content of polyphenols and the antiradical activity of the extracts. The negative correlation was found between the content of polyphenols and the Rancimat test and the chelating activity. It seems that the usage of organic spice extracts in food production could be considered as natural antioxidants, reducing fat oxidation processes to a greater extent than with conventional cultivations.

Beer consumption constitutes a significant portion of alcoholic beverage consumption in Poland. The growing interest in this product has prompted the exploration of solutions that not only affect production technology and costs but also influence the sensory and physicochemical attributes of the beverage. Incorporating unmalted raw materials is one such solution. This research aims to conduct a comparative analysis of haze formation in malted beers and beers with unmalted barley additions, considering diverse storage conditions and production scales. The results revealed that light has a more significant effect on turbidity formation than temperature. In the variants in which the impact of light on haze formation was investigated, the values of the average number of total particles were in the range of 130 (unsweetened laboratory under ultraviolet) to 1025 (unsweetened commercial under ultraviolet). The effect of temperature on haze formation was significantly less. In most cases, the average number of total particles was no greater than 200, with the highest result obtained being 300 (commercial malted under forced aging). Based on the study, it was concluded that, regardless of the scale of production, ultraviolet radiation causes significant haze formation in beer.

The palaeoecology of fossiliferous shales, belonging to the upper part of the Dobruchna Brachiopod Shale Member (= set XIV) of the Skały Formation (northern Holy Cross Mountains), was studied quantitatively in a succession in the transient (1989) trench A, 5.6 m thick, near the village of Skały. The top-Eifelian strata, recording the carbonate crisis during the global Kačák Bioevent, are well known for having a particularly diverse brachiopod fauna. The four brachiopod assemblages, recognised herein, were mainly controlled by the evolving bottom-sediment properties of the outer carbonate ramp basin. Soft, unstable substrates were inhabited by the poorly-diversified Poloniproductus assemblage, associated with a distinctive, ‘incumbent’ set of largely semi-infaunal, generalist species. The pioneer community, as a result of progressive consolidation of bioclast-enriched sediment, evolved toward a more diverse biota. This consequent stabilisation of the substrate resulted in the progressive growth of crinoid thickets or bryozoan-dominated biostromes and patches, associated with rich, subordinate, sessile and vagile benthos. In this stage, diverse brachiopod assemblages were dominated by the pedunculate, eurytopic, ribbed spiriferide Eleutherokomma or specialized orthides (Aulacella, Costisorthis) in the Dobruchna Mbr, and by the expansive, large, free-lying orthotetide Xystostrophia in the overlying set XV of the Skały Fm The cyclic ecological replacement, with the characters of ecological succession in the final phase, was evidently stimulated by an irregular transition from soupy muds to a mosaic of bioclast-rich and firmer, biogenic sediments, within the cyclic pattern of distal tempestite sedimentation. The three episodes of variously reduced deposition rate, recorded in the more diverse benthos, culminated in the pioneer bryozoan/coral reef growth and abundance of epibionts, alternating with times of destructive storm activity and deposition from suspension clouds in the muddy habitats.

The pits that left after exploitation of solid rock minerals are extremely interesting geological objects. They contain records of ancient processes that led to the exposure of rock formations, allowing the timing of these processes. The data obtained from abandoned quarries can be used for scientific studies, but it can also be applied in all activities aimed at popularizing knowledge about a biotic nature. Therefore, these localities should be under legal protection or at least secured against devastation, which often faces considerable difficulties. The Geological Museum has undertaken actions aiming at the protection of abandoned quarries, most often in the form of projects dedicated to geotourism management and creating geotourist trails. These projects are a chance to save important geosites from devastation, overgrowing by vegetation, or fading into oblivion. The article presents case studies of successfully managed old quarries, as well as failed attempts.

Tradycje przemysłu wapienniczego sięgają odległych czasów. Wapno, jako spoiwo zapraw budowlanych i farb używane jest już od kilku tysiącleci. Stare piece wapienne i towarzyszące im wyrobiska spotykane na Wyżynie Krakowsko-Częstochowskiej (a zwłaszcza w jej północnej części) doskonale nadają się do zagospodarowania i wykorzystania w przyszłości jako miejsca edukacyjne ułatwiające poznanie i zrozumienie wielu procesów kształtujących powierzchnię Ziemi, w tym poprzez gospodarczo-przemysłową działalność człowieka. Znane są już ciekawe, krajowe przykłady dostosowania obiektów przemysłu wapienniczego do realizacji funkcji rekreacyjno-poznawczych. Najwięcej jest ich w Sudetach. Autorzy referatu mają nadzieję, że w nieodległej przyszłości dołączy do nich przynajmniej jeden z jurajskich wapienników z okolicy Olsztyna, Rudnik, Częstochowy, Złotego Potoku, Mstowa, Kusiąt lub Choronia.

The traditions of the lime industry date back to distant times. Lime has been used as a binder of building mortars and paints for several millennia. Old lime kilns and the accompanying excavations found in the Kraków-Częstochowa Upland (especially in its northern part) are perfect for development and future use as educational places facilitating the knowledge and understanding of many processes shaping the Earth's surface, including economic and industrial activities of humans. Interesting local examples of adapting lime industry facilities aimed at enhancing recreation and cognitive functions are well recognized. Most of them are in the Sudetes. The authors of the paper hope that in the near future one of the Jurassic lime kilns in the vicinity of Olsztyn, Rudnik, Częstochowa, Złoty Potok, Mstów, Kusiąt or Choroń will also soon become recognizable.

Wytyczne zawarte w biuletynie wydanym przez Europejskie Stowarzyszenie Producentów Laminatów Podłogowych (EPLF) [12] w 2013 r. wymusiły na producentach konieczność wprowadzania nowych podkładów spełniających kryteria określone w specyfikacji technicznej. Najnowsze oczekiwania rynku skierowane są na innowacyjne produkty, które są w stanie spełnić jednocześnie większość parametrów, które wcześniej często się wykluczały. Z naszej wiedzy wynika, że w polskim piśmiennictwie fachowym nie ma opracowania na temat materiałów podkładowych pod laminowane pokrycia podłogowe. W artykule przedstawiono podstawowe informacje o tego typu materiałach oraz wyniki badań nowych, warstwowych podkładów, napełnianych odpadowymi materiałami bitumicznymi, które potwierdzają możliwość opracowania materiałów podkładowych spełniających wymagania EPLF [12].

The guidelines of the European Producers of Laminate Flooring (EPLF) [12], published in its technical bulletin of 2013, have compelled manufacturers to adopt new underlayments that meet technical specification criteria. Today’s consumers demand innovative products that meet the majority of the specifications once thought to be mutually contradictory. To our best knowledge, Polish trade literature is yet to include a work on underlay materials for laminate floor coverings. An introduction to the article provides basic information on such materials. Its experimental part outlines the findings of studies on newly-developed underlayment materials. Studies on such complex multilayered underlayments fitted with bituminous waste demonstrate it is feasible to develop underlay materials that satisfy EPLF requirements [12].
