abstract = {Mitochondrial coenzyme Q (mtQ) of the inner mitochondrial membrane is a redox active mobile carrier in the respiratory chain that transfers electrons between reducing dehydrogenases and oxidizing pathway(s). mtQ is also involved in mitochondrial reactive oxygen species (mtROS) formation through the mitochondrial respiratory chain. Some mtQ-binding sites related to the respiratory chain can directly form the superoxide anion from semiubiquinone radicals. On the other hand, reduced mtQ (ubiquinol; mtQH2) recycles other antioxidants and directly acts on free radicals, preventing oxidative modifications. The redox state of the mtQ pool is a central bioenergetic patameter that alters in response to changes in mitochondrial function. It reflects mitochondrial bioenergetic activity and mtROS formation level, and thus the oxidative stress associated with the mitochondria. Surprisingly, there are few studies describing a direct relationship between the mtQ redox state and mtROS production under physiological and pathological conditions. Here, we provide a first overview of what is known about the factors affecting mtQ redox homeostasis and its relationship to mtROS production. We have proposed that the level of reduction (the endogenous redox state) of mtQ may be a useful indirect marker to assess total mtROS formation. A higher mtQ reduction level (mtQH2/mtQtotal) indicates greater mtROS formation. The mtQ reduction level, and thus the mtROS formation, depends on the size of the mtQ pool and the activity of the mtQ-reducing and mtQH2-oxidizing pathway(s) of respiratory chain. We focus on a number of physiological and pathophysiological factors affecting the amount of mtQ and thus its redox homeostasis and mtROS production level. © 2023 The Author(s).},

abstract = {Background: This paper explains the concept of the Industrial Internet of Things (IIoT) and highlights the benefits of its adoption. The purpose of the study was to identify and evaluate practices and approaches of organisations toward the implementation of IIoT solutions in the packaging industry in Poland. Methods: The results are based on non-sensitive quantitative data collected with the use of a survey questionnaire method and CATI (Computer Assisted Telephone Interview) as a data collection technique. Participants completed anonymous survey questionnaires, with responses analysed collectively without the identification of individuals. No continuous tracking or observation methods were used, and the data did not include personal information such as health, genetics, beliefs, or political views. Results: The results reveal that companies within this industry are not early adopters of IIoT, but they are rather digitally immature, with a poor degree of IIoT implementation, poor degree of quality systems digitisation, and no plan towards transformation to enterprise systems such as MRP, ERP, or CRM. The application of IIoT has potential for improvement. The paper outlines the analysis of organisational culture in terms of supporting innovation and continuous improvement, showing that the level of support is moderate, however, the bigger company is, the more supporting the organisational culture it has. Conclusions: Data reveal that the application of IIoT solutions in the packaging industry in Poland is still not very common. Poor adoption of IIoT may be related to fear of technology, budgetary issues, or lack of qualified staff. Although digitisation already changed the software and the hardware side of organisations, most of them are not digitally mature enough to be able to take advantage of the fourth industrial revolution, which can be a strategic advantage for early adopters. © Wyższa Szkoła Logistyki, Poznań, Polska.},

abstract = {This study aimed to identify differences in organic matter (OM) composition and origin in the main depositional subenvironments within the floodplain of a meandering river in a temperate climate zone. The study analysed organic-rich sediments found within different facies (side bars; natural levees; crevasse splays; palaeochannels; flood basins; and alluvial fans). Quantitative macrofossil analysis of the OM present in proximal floodplain sediments pointed to a dominance of amorphous OM (AOM), the average proportion of which comprised up to 60% of the total OM. During floods, the most significant phenomenon is the deposition of wood and leaf debris; however, these debris are subject to rapid decomposition in sandy layers and, as a result, do not contribute much to the total OM composition. Root and epidermis remain accumulated in situ and, with an average share of more than 10% of the total OM, are an important part of the more fine-grained alluvial layers. The other components were no more than bioindicators. The proximal floodplain is characterised by sponge spicules in the alluvia and mycelia in the epipedons. In addition, diatom remains are often recorded in the flood layers. The average AOM content in the OM found within the distal floodplain was approximately 40%, although a significantly higher proportion of this component was recorded in flood basin sediments. The accumulation of rhizodermis, epidermis, wood, and periderm (with shares ranging from 5% to 22% of the total OM) plays an important role. Less common components that are of indicative value within the distal zone include the remains of mosses, Cladocera, and sporomorphs. OM within the distal floodplain has high preservation potential, and the sediments in this zone are crucial for carbon sequestration processes in river valleys. © 2022 The Author},

abstract = {Over the last decades, we have witnessed an increasing interest in food-related products containing vegetable oils. These oils can be obtained either by extraction or by mechanical pressing of different parts of plants (e.g.; seeds; fruit; and drupels). Producers of nutraceuticals have ceaselessly searched for unique and effective natural ingredients. The enormous success of argan oil has been followed by discoveries of other interesting vegetable oils (e.g.; pomegranate oil) containing several bioactives. This work describes the pomegranate fruit extract and seed oil as a rich source of conjugated linolenic acid as a metabolite of punicic acid (PA), deriving from the omega-5 family (ω-5). Through the chemical characterization of PA, its nutritional and therapeutic properties are highlighted together with the physiological properties that encourage its use in human nutrition. We analyzed the composition of all fatty acids with beneficial properties occurring in pomegranate seed oil using gas chromatography (GC) with flame-ionization detection (FID) analysis combined with Fourier transform infrared spectroscopy (FTIR). Pomegranate seed oil mainly consists of 9,11,13-octadic-trienoic acid (18:3), corresponding to 73 wt % of the total fatty acids. Nine components were identified by GC in PSO, varying between 0.58 and 73.19 wt %. Using midinfrared (MIR) spectroscopy, we compared the composition of pomegranate seed oil with that of meadowfoam seed oil (MSO), which is also becoming increasingly popular in the food industry due to its high content of long chain fatty acids (C20-22), providing increased oil stability. From the results of FTIR and MIR spectroscopy, we found that punicic acid is unique in PSO (73.19 wt %) but not in MSO. © 2022 by the authors.},

abstract = {Wet chemistry methods are traditionally used to evaluate the quality of a coffee beverage and its chemical characteristics. These old methods need to be replaced with more rapid, objective, and simple analytical methods for routine analysis. Near-infrared spectroscopy is an increasingly popular technique for nondestructive quality evaluation called a green technology. Our study aimed to apply near-infrared spectroscopy to evaluate the quality of coffee samples of different origin (Brazil; Guatemala; Peru; and Congo). Particularly, we analyzed the roasting time and its effect on the quality of coffee. The colorimetric method determined a relation between the coffee color and the time of roasting. Partial least squares regression analysis assessed a possibility of predicting the roasting conditions from the near-infrared spectra. The regression results confirmed the possibility of applying near-infrared spectra to estimate the roasting conditions. The correlation between the spectra and the roasting time had R2 values of 0.96 and 0.95 for calibration and validation, respectively. The root mean square errors of prediction were low – 0.92 and 1.05 for calibration and validation, respectively. We also found a linear relation between the spectra and the roasting power. The quality of the models differed depending on the coffee origin and sub-region. All the coffee samples showed a good correlation between the spectra and the brightness (L* parameter), with R2 values of 0.96 and 0.95 for the calibration and validation curves, respectively. According to the results, near-infrared spectroscopy can be used together with the chemometric analysis as a green technology to assess the quality of coffee © 2022, Wójcicki.

abstract = {In the Odra and Osob³oga River valleys in the vicinity of the town of Krapkowice, a system of morphological levels is present which is exceptionally extensive compared to other such systems in southern Poland. The extent, origins and chronology of these levels have been the subject of many controversies. In the light of current research, the terraces, which are situated on average 14.5-13, 12-10, 8-6, 6-4 and 3-1 metres above the river level, were formed in the post-Wartanian interval. The main factor driving their development was erosion, which compensated for the effects of large-scale aggradation that had occurred during the anaglacial phase of the Odranian Glaciation (MIS 8) dated to 261 ±15 ka. The impact of climatic conditions on the trends towards fluvial erosion or accumulation was only of secondary importance. According to OSL dating, successive phases of vertical stabilisation of the valley floor occurred ~118.8 ±8.3, 87.7 ±5.7 and 42.0 ±2.0 ka. In the meantime, erosion intensified, which resulted in the formation of lower terrace levels. During the climatic minimum of the Upper Plenivistulian (21.5 ±1.5 ka), under conditions of the delivery of sheet-wash-generated sediment, the aggradation of distal reaches of the Odra River valley was locally marked. During the Late Vistulian and Holocene, erosive tendencies continued, which were reflected by the fact that the surfaces of subsequent inset alluvial fills were situated ever lower. In the light of dating results, it can be concluded that during the colder periods correlated with the Rederstall Stadial (MIS 5b) and with the Hasselo Stadial (MIS 3), a braided river was present in the river valleys examined, which was most probably accompanied by permafrost. During the Eemian Interglacial (MIS 5e), during the Late Vistulian Interstadials and in the Holocene, it was a meandering river. © 2020, Polish Geological Institute. All rights reserved.},

abstract = {During litho-stratigraphic studies of deposits in small mires in the upper basin of the Oder River, mid-Holocene hiatuses identified by the presence of horizons of strongly decomposed peat (HSDP), were identified at four sites. Radiocarbon dating results indicate long (103 years) breaks in peat accumulation and the dates obtained from the underlying layers of deposit are inconsistent with the pollen record. In order to explain these discrepancies, an attempt was made to recreate the conditions of HSDP formation under the influence of endo-and exogenous factors determining peatland productivity. In the light of macrofossil analysis, the development of HSDP during the Atlantic and Subboreal periods, when the humidity of habitats decreased, occurred at an advanced stage of development of swamps with Alnetea glutinosae forest communities. The gradual rise in water levels in the mires that started in the Subboreal period and intensified during the Subatlantic period was recorded as a slow shift in vegetation towards non-forest, sedge-moss communities belonging to the Magnocaricion alliance or the Scheuchzerio-Caricetea nigrae class. One consequence of the mechanism of HSDP formation is the existence of limitations on the dating of the duration of the dry phase owing to the presence of organic matter of different ages in the degraded peat layer. The determination of the age of wet phases offers better prospects. In the light of radiocarbon dating, which is essentially in line with the pollen analysis results, the transition towards positive peatland productivity occurred between ca. 9th century BC and 7th century CE. © 2016 K.J.

abstract = {The analysis of the positive feedback between landslides and erosion requires determination of the precise temporal and spatial relations between events of colluvium delivery and fluvial erosion. In our study we use decennial datasets on the occurrence of landsliding and erosion achieved through dendrochronological methods. Four sites covering areas of landslide slopes and adjacent valley floors with stream channels were studied. Landsliding on slopes was dated from the tree-ring eccentricity developed in stems tilted due to bedrock instability. Erosion in channels was dated using the wood anatomy of roots exposed by erosion of the soil cover. Analysis of the temporal relations between dated landsliding, erosion and precipitation record has revealed that two types of repeating sequences can be observed: (1) rainfall→landsliding→erosion; (2) rainfall→erosion→landsliding. These sequences are an indication of the occurrence of slope-channel positive feedback in the sites studied. In the first type, landsliding triggered by rainfall delivers colluvia into the valley floor and causes its narrowing, which in turn causes increased erosion. In the second type erosion triggered by rainfall disturbs the slope equilibrium and causes landsliding. Landsliding and erosion, once triggered by precipitation, can occur alternately in years with average precipitation and reinforce one another. Bidirectional coupling between landsliding and channel erosion was shown notably through the effects of channel shifting and forced sinuosity and by increased erosion of the slopes opposite the active landslides. Observations also suggest that the repetition of sequences described over longer periods of time can lead to a general widening of the valley floor at the expense of slopes and to a gradual change of the valley cross-profile from narrow, V-shaped into a wide flat-bottomed. Thus landsliding-erosion coupling/positive feedback was recognized as an important factor shaping hillslope-valley topography of the mid-mountain areas studied. © 2014 John Wiley & Sons, Ltd.},

In such circumstances, deposit sequences usually begin with aquatic detrital sediment (gyttja), or possibly brown-moss or reed peat. These deposits normally pass into sedge-reed peat and then alder peat. If the accumulation of organic-rich deposits was initiated by paludification, alder peat appears in the lowest sections of the fens. In the upper parts of the sequences, apart from wood peat, organic deposits dominated by sedge remains are also present.

abstract = {The work examines the timing and environmental conditions of floodplain sedimentation in the valleys of the upland Kłodnica and piedmont Osobłoga rivers in the Upper Odra River basin. A distribution of 52 14C-ages shows relatively high floodplain sedimentation at the Late Glacial-Holocene transition, more stable floodplain environments since the Early (in the Kłodnica Valley) and Middle Holocene (in the Osobłoga Valley) and a gradual increase in floodplain deposition in the Late Holocene (since <3.4kyr BP). Organic matter [OM] and mineral matter [MM] fluctuations were correlated with variables responsible for the activation of erosion (i.e. vegetation changes; human impact and hydrological events) as well as factors affecting the local record of sedimentation (i.e. valley morphology; hydrologic conditions and episodes of local erosion). A clear relationship is shown between an increase in alluviation and climate- or human-induced extension of unforested areas. The deposition of mineral-rich sediments increases rapidly during periods characterized by non-arboreal pollen values exceeding approximately 8% in pollen diagrams. On the other hand, the results obtained do not confirm significant interactions between Holocene changes in forest composition and alluviation. Despite the settlement of agrarian groups, the sedimentary record of human activity in the Osobłoga catchment is very poor during the Neolithic and early Bronze Age. A large-scale alluviation of the Osobłoga and Kłodnica valleys was initiated during the settlement of people of the Lusatian culture from the middle Bronze Age and escalated in the early Middle Ages and Modern Times. The deposition of products of soil erosion was limited to between ca. 1.9-1.2kyrBP, probably due to demographic regression during the Migration Period. Comparison of OM/MM fluctuations with phases of increased fluvial activity does not show a relationship between Holocene wetter phases and catchment sediment yield. Sedimentary episodes in the Upper Odra basin also show a low degree of correlation with the probability density curve of the 14C-ages. The results obtained in the Kłodnica and Osobłoga valleys indicate a strong to moderate correlation between the spatial distribution of the study sites and the origin of MM-rich deposits, but a weak correlation between the spatial distribution of the study sites and TOC content. Such a pattern suggests that OM/MM fluctuations relate predominantly to the changes in sediment yield, although morphological conditions have a significant impact on the capture potential of sedimentary basins during phases of alluviation. Additionally, high OM content is not a simple function of an increase in wetness of the sedimentary environment. On the other hand, hydrologically-conditioned hiatuses as well as erosion episodes impoverish the sedimentary record, complicating the consideration on the geochronology of deposits and making it difficult to calculate reliable accumulation rates. However, they do not reduce the value of OM/MM fluctuations as an indicator of alluviation events for a preserved series of sediments. © 2012 Elsevier B.V.},

abstract = {The goal of studies in the Ruda and Kłodnica valleys was to establish denudation intensity corresponding to phases of farming and breeding economy. Research was aimed at defining chronology of sedimentation of overbank, proluvial fan and sheetwash deposits. It was affirmed that (1) denudation at the end of the Bronze Age and during the Hallstatt and Roman Periods of the Iron Age reached relatively low intensity in comparison to population density at that time, (2) strong increase of denudation occurred in the older part of the Early Middle Ages in spite of demographic regress at that time, (3) the highest denudational rate was noticed throughout historical times. Additionally, studies show that proluvial fan and sheetwash deposits can be treated as indicators of the close neighborhood of a settlement. Overbank deposits can record shifts occurring in a larger distance from deposition zone, though their extension and thickness decrease along with distance growth from the area transformed under influence of human activity.},

The formation of the inset alluvial fills by a meandering river started during the Early Holocene at the latest; however, the absence of a clearly developed system of large Late Vistulian palaeomeanders is notable within the analysed reach of the valley. Mid- and Late Holocene alluvial series were deposited by a river that exhibited a tendency to decrease in channel sizes. Nevertheless, large meanders were formed again in historical times. Oxbow fills in the Odra River valley are dominated by mineralogenic deposits. Their sedimentation can be correlated with the accretion of overbank and colluvial sheets in the valley floor. In the light of radiocarbon chronology, a relationship between Neolithic and subsequent phases of settlement in the catchment and the intensive deposition of these sediments cannot be ruled out.},

abstract = {Lithological analyses and radiocarbon dating were used to elucidate the patterns and controls of Late Quaternary valley floor development of the Kłodnica River, the Upper Odra Basin. The research results were discussed with data obtained from valleys of rivers draining piedmont basins and highlands of southern Poland. In consequence, five stages of morpho-sedimentary evolution of the Kłodnica valley were distinguished. In the Late Vistulian a large-scale deposition of channel alluvium took place in the conditions of high river discharges. This sedimentary style probably still existed in the Early Pre-Boreal as long as open grass communities survived in the Kłodnica catchment. The next phase, in the Late Pre-Boreal and Boreal, is characterized by a significant increase in accumulation rate of biochemical facies. The considerable restriction of minerogenic deposition was connected with widespread of forest and gradual limitation of the river discharges. The third stage began at the decline of the Boreal and was defined by decrease of accumulation rate or even biogenic accumulation break. Synchronously, periodic increases of fluvial activity were noticed in the form of cutoffs of meander loops and overbank deposition in oxbows. The beginning of the fourth period took place not earlier than in the Early Sub-Boreal. This stage was distinguished by renewed peat growth/increase in biochemical accumulation rate and periodic increase in alluviation, generally taking place in the conditions of low channel-forming flows. The latest phase (from the Middle Sub-Atlantic till now) is characterized by common initiation of slope deposition and a rapid increase in fluvial sedimentation, especially overbank and tributary fan facies. An increase in minerogenic deposition occurred in response to human impact, which became more significant from the Roman Period and occurred on a large scale from the early Middle Ages. Older settlement phases, including intense settlement from the Hallstatt Period, were not clearly recorded in the Kłodnica valley fill.},

abstract = {Research was conducted in valleys of sinuous rivers that drain medium-high mountain, foreland basin and upland areas, where loose Quaternary deposits predominate. The cyclic pattern determined for deposits of the oxbow sedimentary subenvironment in the Upper Odra Basin can be expressed as a few alternative sequences. The best-developed cycle occurring on a relatively high level of probability, is represented by the unilateral transition from channel to overbank deposits and upwards-bilateral oscillations between overbank and biochemical, as well as biochemical and slope deposits. In the first stage, oxbow filling processes are usually determined by autocyclic factors (resulting from spatial relations between abandoned channels and the active channel). As a consequence, overbank and/or biochemical sediments usually overlie channel deposits. Later, allocyclic processes could easily dominate autocyclic processes. In these cases, overbank, slope and late-Holocene alluvial fan deposits were delivered to oxbow basins as a result of the influence of outside factors such as climate or human impact. In the Upper Odra catchment, facies succession in the sequences of deposits infilling abandoned channels was mainly determined by climatic factors (in the Late Vistulian; early and mid-Holocene) and anthropogenic factors (in the late Holocene; especially in the last dozen centuries or more). The course of sedimentary processes conditioned by climate and human activity was modified by orographic factors associated with spatial relations among abandoned channels and both the active channel as well as valley slopes. However, the geological structure had a smaller influence on the course of sedimentary processes in the oxbows. The diversity of bedrock lithology in the individual drainage areas determined the thickness and lithological features of the given series of deposits but not the facies succession. © 2006 Edward Arnold (Publishers) Ltd.},

abstract = {The article presents results of research on the mechanism of filling abandoned river channels, considering an environmental background. Sequences of sedimentary fills of palaeochannels of different ages were analysed. The research was carried out in the Ruda, Kłodnica and Osobłoga valleys, which belong to the Upper Odra fluvial system (southern Poland). It was assumed that palaeochannels may have been filled with deposits of the following facies: overbank [ob], slope [s], alluvial fan [af], aeolian [e], and biochemical [bc]. Channel facies [ch] was the starting point in the analysis. Facies analysis proved that typical sequences for palaeochannels of older generation were: [ch] → [bc] ⇆ [ob] in the Ruda valley, [ch] → [bs] → [s] or [ch] → [ob] ⇆ [bc] → [s] in the Kłodnica valley, [ch] → [ob] → [s/af] or [ch] → [ob] ⇆ [bc] → [s/af] in the Osobłoga valley. Typical sequences for palaeochannels of younger generation were: [ch] → [ob], or more rarely (in the Ruda and Kłodnica valleys) [ch] → [ob] → [bc]. Facies analysis showed that depositional processes taking place in palaeochannels were strongly independent in relation to oxbow development phases. Irrespective of whether accumulation occurred in subaquatic, telmatic or terrestrial conditions, environmental variables (climate; geology; relief and human activity) have had major influence on the facies record within valley floors. In the considered catchments the origin of deposits infilling the palaeochannels were mainly conditioned by following factors: climatic (in the Late Vistulian and the older and middle of Holocene) and anthropogenic (in the late Holocene; especially in the last few centuries). The course of climatically or anthropogenically conditioned sedimentation was modified by topographic factors. The appearance of biochemical facies [bc] and, in some cases, of overbank facies [ob] in the sequences of palaeochannel fills may be related to external factors (mainly climatic) affecting the whole drainage area. Deposits of slope facies [s], alluvial fan facies [af], and overbank facies [ob] containing charcoals are the effect of denudation processes of local extent. These processes are often initiated by deforestation, mainly as a result of river catchment management. Their intensity depends on relief characteristics of the valley reach considered.},

abstract = {Present climatic conditions of the Fan Mountains are conducive to physical weathering, which leads to intensive production of limestone coarse debris covers. In the Fan Mountains, being an example of glaciated mountain systems, two altitudinal belts (cryonivo-glacial and fluvio-denudational) have been distinguished. Within the cryonivo-glacial belt, the most intensive transfer of weathered materials occurs as a result of glacial and gravitational (rapid mass wasting) transport systems' activity. In effect of these processes slope covers are formed, characterized by an open work texture and in the case of rockfall deposits additionally fractional grading. Covers of the same structure are common also within the fluvio-denudational belt. In this zone, rapid mass wasting performs a function of dominant transport system within slopes' boundaries. In humid periods, debris flows and landslides are additionally of significant importance as an agent of weathered materials transport. As an effect of older deposits redeposition by landslides, unsorted, matrix-supported colluvial covers are formed. During average hydrometeorological conditions, the individual Fan Mountains transport systems show a far-reaching independence. Deposition of glacial denudation products occurs within the zone of Kulikalon-Dušacha postglacial lakes proceeded only by proglacial rivers' short-distance transport. Rapid gravitational movements' deposits are accumulated in foot zone of steep slopes and they are not directly transferred to the channel system. Periodically, in humid conditions especially in the spring, glacial, denudational, and fluvial systems are linked. In these conditions, alluviation of slopes by debris flows has been observed.},

abstract = {The investiations in the Ruda valley (the Subcarpathians Depressions, south Poland) indicate the lithological differentiation of the deposits infilling two generations of the palaeomeanders - the older and younger ones. This fact enabled to distinguish two phases of the Holocene activity of the Ruda channel. The palaeomeanders date by the radiocarbon method to 6 690 ± 100 BP, 6 010 ± 120 BP and 5 680 ± 120 BP document the older phase, characterised by the stability of the relief and hydrological conditions within the Ruda drainage basin. The palaeomeanders are infilled mainly with the organic deposits. The Ruda channel activity was much reduced, however the silty intercalations indicate the episodes of the limited flood influence on the oxbows. The sandy-gravely intercalations existing within the palaeomeander deposits are of less interpretational significance as they exhibit the local processes only. The younger Holocene phase of the Ruda channel activity initiated in the early Middle Ages and has been characterised by the violent increase in the intensity of the valley-modelling processes. The palaeomeanders of this period are infilled with the overbank lithofacies. The increase in the river bed load was most probably conditioned by the rural colonisation of the Ruda drainage basin. The growth of the river competence as well as the bed load was responsible for the intensified erosional possibilities, which is well documented in the river alluvia. This effected in the decrease in the present-day meander sizes and resulted in the formation of the terrace succession creating the lower level of the Holocene valley floor.},
