Opis:
The present article describes selected aspects of investment casting technology for manufacturing of open-cell aluminium. The main focus is, among others, on the precursor thickening. Two groups of total 30 samples were produced, basing on open-cell polyurethane foam used as the precursor. Each of the two sample groups was thickened with a different type of suspension consisting of carbonaceous substances and organic binders. The influence of the coating mixture type was compared, leading to conclusions regarding the desired composition and fluidity of the suspensions. Both sample groups of the obtained open-cell aluminium had stochastic cell distributions, the average pore diameter was 5.2 mm and the PPI index was 8. The apparent densities were respectively: 0.485 g/cm3 and 0.312 g/cm3 , which reflected the impact of the precursor coating. Additionally, samples from both groups differed in quality.

Opis:
This paper describes a new hexactinosidan hexactinellid Guettardiscyphia zitti sp. n. on the basis of a detailed study of 279 specimens from 12 localities in the southern part of the Bohemian Cretaceous Basin. All the studied material comes from the basal Bílá Hora Formation (Lower Turonian). The geology and palaeontology of the sponge-bearing strata at studied locations exhibit identical palaeoenvironmental settings: 1 - transgressive character of sediments with low sedimentation rates, 2 - presence of submarine swells formed by crystalline basement, 3 - hemipelagic sedimentation below the storm-wave base, and 4 - the presence of proliferating diverse sponge faunas with subordinate accompanying macrofaunal remains.

Opis:
The use of commercial sponges in materials science has gained much recent attention. Their unique properties, namely a fibrous, rigid skeleton, thermal stability and resistance to acid and basic hydrolysis, have been the primary motivation to use them in the development of new composites. In this work, a simple method of immobilization of cobalt and silver cations, followed by their reduction using sodium borohydride, was successfully applied for the first time to obtain functionalized spongin scaffolds. Three different materials, labeled Co_spongin, Ag_spongin and Co-Ag_spongin, were prepared. Their morphological and physicochemical properties were explored using various techniques (SEM+EDS, TG/DTA, FTIR). The focal point of the research was the application of the resulting materials in the reaction of 4-nitrophenol reduction with sodium borohydride in water. It was found that all of the composites possess superior activity in the reduction of 4-nitrophenol, achieving high rate constants of 0.31 min-1 for Ag_spongin, 0.52 min-1 for Co_spongin and 0.86 min-1 for Co-Ag_spongin. Reusability tests showed that all of the composites could be reused five times. Additional structural analysis after catalytic application showed no visible changes in the morphology of the catalysts. The results indicate that spongin can be considered as a facile, cost-effective, renewable and environmentally friendly three-dimensional support for use in heterogeneous catalysis.

Opis:
The Anisian shallow-marine Karchowice Beds of the Upper Silesia represent reefal habitats and circum-reefal environments, where biological-mechanical interactions determine sedimentary processes and facies pattern. The purpose of this study was recognition of the interaction between biological and mechanical controls of carbonate deposition. Such interdependence resulted in considerable lateral variability of thickness and lithological features, observed at a distance of 25 km. The western part of the basin is dominated by proximal facies (reefal facies), whereas the eastern one represents distal facies (fore-reef). Sedimentary succession in the western area is twice as thick than the eastern one. It resulted from different rate of subsidence owing to block tectonics, controlled by reactivated ancestral Silesian-Moravian Fault. Small-scale synsedimentary faults confirm syndepositional tectonic activity in the region. Palaeogeographical position caused that the Upper Silesia was strongly affected by monsoon climate, generating storms. These storms contributed to episodic deposition, prevailing during the sedimentation of Karchowice Beds. However, most of time was represented by prolonged non-deposition periods, recorded as interstratal hiatuses, but also by forming of firmgrounds, micritization and coating of bioclasts or substrate recolonisation by organisms.

Opis:
Chitin of poriferan origin represents a unique renewable source of three-dimensional (3D) microtubular centimetre-sized scaffolds, which have recently been recognized as having applications in biomedicine, tissue engineering, and extreme biomimetics. The standard method of chitin isolation from sponges requires concentrated solutions of acids and bases and remains a time-consuming process (lasting up to seven days). Here, for the first time, we propose a new microwave-based express method for the isolation of chitinous scaffolds from the marine demosponge Aplysina aerophoba cultivated under marine farming conditions. Our method requires only 41% of the time of the classical process and does not lead to the deacetylation of chitin to chitosan. Alterations in microstructure and chemical composition due to the microwave treatment were investigated using various analytical approaches, including Calcofluor White staining, chitinase digestion, scattering electron microscopy, and Raman and ATR-FTIR spectroscopy. It was demonstrated that microwave irradiation has no impact on the chemical composition of the isolated chitin.

Opis:
The objective of this study was to determine the biodegradability of bioplastic materials – sponge cloths – available on the European market that are labeled as 100% biodegradable but not certified as compostable. The test was carried out in a controlled composting environment. The project length was 22 weeks. The emphasis was put on discovering whether the sponge cloths are biodegradable or not. Based on the results thereof it can be concluded that sponge cloths have not decomposed completely but their color has changed and that degradation and physical changes occurred. Samples A1, and A2 have not decomposed completely and exhibited very slow degradation rate. Sample B5 exhibited the highest degradation rate. Samples B3, B4 exhibited high degree of decomposition. The main conclusion from this study is that biodegradation of bioplastics materials strongly depends on both the environment in which they are placed and the chemical nature of the material.

Opis:
The article is focused on the problem of green infrastructure, which effectively helps to reduce the effects of floods and water deficit in cities. It presents examples of good practices implemented in China. In the end of 2014, China’s national government initiated the “sponge city” project. A “sponge city” is a city built around the concept of managing water in an ecologically sustainable way by imitating natural hydrological cycles in the city, which translates into the restoration of the ability to absorb, infiltrate, store and purify rainwater in urbanized, highly sealed spaces. In “sponge cities”, flood risk management is included in the mainstream of urban planning and has the appropriate legal framework. The intention is to improve urban resilience through rainwater capture, storage and use by means of green roofs, pavements made of permeable materials, tumbles, rigoles, retention ponds, water squares, rain gardens and creating wetlands parks.

Opis:
Part of the Oxfordian carbonate buildups in the southern part of the Kraków Upland is developed as pseudonodular limestones, which represent segment reefs. These limestones are composed of connected, rounded-oval to subangular carbonate pseudonodules. The pseudonodules, densely packed within the limestone, fall out easily under mechanical stress. The recently observed texture of pseudonodular limestones resulted from two stages of chemical compaction. During the first stage, in the Late Jurassic, high-amplitude and low-amplitude stylolites and dissolution seams were formed. The sites particularly favourable for the development of high-amplitude stylolites were the boundaries between already lithified fragments of the laminar, rigid microbial-sponge framework. The low-amplitude stylolites formed mainly in the intercalated wackestone-packstone, which was lithified somewhat later; hence, the dissolution seams originated at the contacts between the rigid microbial-sponge framework and the wackestonepackstone. After Early Cretaceous erosion, which decreased the burial load, Late Cretaceous sedimentation enabled the renewal of pressure dissolution. Thus, some low-amplitude stylolites evolved into dissolution seams. In stylolites composed of both low- and high-amplitude segments, dissolution proceeded at the bases of interpenetrating high-amplitude stylolite columns, with the simultaneous transformation of low-amplitude stylolite segments into dissolution seams. These seams, which formed at the initial stage of chemical compaction, were subjected in turn to further pressure dissolution, giving rise to the formation of horsetail structures. The vertical stress field, which triggered the pressure dissolution processes, presumably resulted in the formation of high-angle and vertical incipient tension gashes. At the beginning of the processes, these gashes remained closed. In the Cenozoic, under the extensional regime generated by overthrusting Carpathian flysch nappes, some high-angle and vertical dissolution seams and low-amplitude stylolites opened up, forming deformed dissolution seams and deformed stylolites. Under the same conditions, the high-angle and vertical tension gashes opened up as well. Subsequently, during the exposure period, unloading fractures developed, partly as a result of the opening of some subhorizontal and horizontal dissolution seams and stylolites. The unloading fractures, along with the already existing vertical and high-angle tension gashes, formed the network changing the limestone into pseudonodules of various shapes and sizes. The open spaces between the limestone fragments became local conduits for karst waters.

Opis:
Turbiditic silty and sandy intercalations in the Turonian Variegated Shale from the Silesian Nappe (Polish Outer Carpathians) contain numerous sponge spicules among siliciclastic fine-grained particles. The highest amount of spicule admixture is nearly 50%. In such layers, they create spiculitic sublitharenite microfacies. These sponge spicules contain forms belonging mostly to the Lithistida group (97% of morphotypes), with a small admixture of spicules from the Hexactinellidae group. Tetraclones with a high content of different types of triaenes dominate among desmas, what indicates the dominance of sponges from subfamily Tetracladina. The preservation state of spicules is generally poor. The Variegated Shale deposits that contain the sponge spicules were accumulated in a deep sea basin, below the calcium compensation depth. Most probably, the spicules were derived from loose material accumulated earlier in various parts of the basin slopes, from which they were exhumed and again redeposited by turbidity currents during the Turonian times.

Opis:
Mid-Cretaceous turbidites with large proportions of sponge spicules are widely distributed in the Silesian Nappe of the Outer Carpathians, giving rise to diversified types of sediments, from spiculites to spicule-bearing siliciclastics and calcarenites. Part of this succession, Middle–Late Cenomanian in age, was transformed into cherts. A microfacies study showed that these turbidite sediments underwent several stages of calcitization and silicification, which took place during Mid-Cretaceous times in different sedimentary environments, i.e., on a northern shelf bordering the Silesian Basin and on a deep sea floor. The first diagenetic changes were related to changes to the biotic components of the turbidite layers, dominated by siliceous sponge spicules. This process, which took place in the spiculitic carbonate mud on the shelves, was related to the calcitization of sponge spicules. Calcareous clasts and calcified skeletal elements also were corroded by bacteria. After transportation down the slope, the biogenic and siliciclastic particles were deposited below the carbonate compensation depth. Taphonomic processes on the basin floor and alternating phases of carbonate and silica cementations, recrystallization and dissolution occurred in these sediments and were related to the diversification in composition of successive turbidite layers. Silicification was related to the formation of quartz precipitates as fibrous chalcedony or microcrystalline quartz, which were derived from the earlier dissolution of amorphous silica, originating mostly from siliceous sponge spicules and radiolarian skeletons. However, a source of silica from hydrothermal vents was also possible. The initial silica precipitation could have taken place in a slightly acidic environment, where calcite was simultaneously dissolved. A number of silicification stages, visible as different forms of silica precipitate inside moulds after bioclasts, occur in the particular turbidite layers. They were related to changes in various elements of the pore-water profile after descending turbidity-current flows. A very low sedimentation rate during the Middle–Late Cenomanian in the Silesian Basin may have favoured the sequence of initial calcitization and silicification stages of the turbidite sediments.

Opis:
Drug sensitivity assay was performed using two human tumour celi lines: HeLa and Hep-2 cultivated in two-dimensional monolayer celi cultures and three-dimensional cultures on gelatine sponge SpongostanK. Two cytostatics with different mechanisms of anti-tumour action were used: cisplatin and etoposide. Chemosensitivity of tumour cells was assessed by counting the number of viable and nonviable cells (cytostatic and cytotoxic activity of drugs), by counting the number of apoptotic cells and by clonogenic assay of viable cells. We found that the clonogenic assay was morę sensitive than the other tests used, especially after long-term (7 days) treatment of tumour cells with cytostatics. A short (24h) treatment with cytostatics gave false results which were not confirmed after prolonged treatment with cytostatics. We suppose that short treatment tests should not be used for examination of the chemosensitivity of tumour cells isolated from patients. Tumour cells growing on SpongostanH were viable for a longer time than in monolayer cultures and exhibited chemosensitivity comparable to monolayer celi cultures despite of their multilayer growth on gelatine sponge.
Do badań wrażliwości na cytostatyki użyto dwie ludzkie linie nowotworowe: HeLa i Hep-2, hodowane w formie murawy dwuwymiarowej (płaskiej) oraz w formie przestrzennej, trójwymiarowej, na gąbce żelatynowej Spongostan". W badaniach użyto cytostatyki posiadające różny mechanizm działania przeciwnowotworowego, a mianowicie cisplatynę i etopozyd. Wrażliwość komórek nowotworowych na chemioterapeutyki określano ilością komórek przeżywających i martwych (cytostatyczne i cytotoksyczne właściwości leków), ilością komórek apoptotycznych oraz oceniano klonogenne właściwości komórek przeżywających. Stwierdzono, że ocena klonogennych właściwości komórek jest metodą bardziej czułą w porównaniu z innymi testami, szczególnie po długim (7-dniowym) kontakcie komórek z cytostatykami. Ocena krótkotrwałego (24-godz.) kontaktu komórek nowotworowych z cytostatykami dawała fałszywe wyniki, nie potwierdzone po długotrwałej inkubacji komórek z cytostatykami. Uważamy, że testy polegające na ocenie efektu krótkotrwałej inkubacji komórek z lekami nie powinny być stosowane do oceny wrażliwości na chemioterapeutyki komórek nowotworowych izolowanych od pacjenta. Komórki nowotworowe rosnące na Spongostanie” były żywe dłużej niż rosnące w hodowlach płaskich i pomimo wielowarstwowego wzrostu na gąbce żelatynowej wykazywały wrażliwość na leki porównywalną z hodowlami płaskimi.
