Opis:: Bartłomiej Lis
For various reasons, large storage vessels rarely attract the attention of pottery specialists. It is quite remarkable that prehistoric pithoi from the Greek mainland have not received a thorough treatment so far, in contrast to their Cretan or Cypriot counterparts. The article attempts to fill partially the gap and to show the potential of such a study for approaching wider issues of social, economic, and political developments of LBA/EIA Central Greece. The majority of the pithoi derive from the site of Mitrou. Fragments from two other sites located nearby—the settlement of Kynos and the sanctuary at Kalapodi—complete our dataset. The outstanding characteristic of these pithoi is their size and decoration, consisting of designs made by impressions of a toothed tool. Macroscopic analysis of fabrics supports the existence of several workshops serving more than a single site. Various lines of interpretation of the distributional pattern and the sudden rise of this type of pithos (and pithoi in general) at the LBA/EIA transition are suggested and elaborated.

Quantitative and Qualitative Composition of Bacterial Communities of Malting Barley Grain and Malt during Long-Term Storage. Agronomy. 2020; 10(9):1301. https://doi.org/10.3390/agronomy10091301 ; (https://www.mdpi.com/2073-4395/10/9/1301)
Opis:: In the grain samples of three malting barley varieties harvested in 2016, and in the malt made from them, we observed microbial changes during storage. Analyses were performed after 0, 3, 6, and 9 months of storage in floor warehouses and silos. We monitored microbial changes based on the quantitative determination of microorganisms using a plate dilution method and qualitative determination of microorganisms, where we identified a particular species of bacteria using the MALDI-TOF MS Biotyper instrument (Bruker Daltonics, Bremen, Germany). Based on the quantitative determination of microorganisms, we found that the total plate counts of microorganisms was higher in malts than in barley grains. The storage period had the greatest impact on the number of coliform bacteria, which gradually increased with the growing months in storage. The number of lactic acid bacteria in barley grains with the growing months in storage and malt produced from them decreased slightly, and the content of the sporulating bacteria in all the samples fluctuated slightly. Differences in the numbers of observed microorganisms were negligible during storage between floor warehouses and silos. In the samples of barleys, the most commonly identified species were Pantoea agglomerans, which was also present in malt samples but did not belong to the dominant species. A diverse species representation appeared in the samples, whereas predominating species belonged to the Enterobacteriaceae family.

Opis:: Establishing green and reliable energy resources is very important to counteract the carbon footprints and negative impact of non-renewable energy resources. Metal-organic frameworks (MOFs) are a class of porous material finding numerous applications due to their exceptional qualities, such as high surface area, low density, superior structural flexibility, and stability. Recently, increased attention has been paid to surface mounted MOFs (SURMOFs), which is nothing but thin film of MOF, as a new category in nanotechnology having unique properties compared to bulk MOFs. With the advancement of material growth and synthesis technologies, the fine tunability of film thickness, consistency, size, and geometry with a wide range of MOF complexes is possible. In this review, we recapitulate various synthesis approaches of SURMOFs including epitaxial synthesis approach, direct solvothermal method, Langmuir-Blodgett LBL deposition, Inkjet printing technique and others and then correlated the synthesis-structure-property relationship in terms of energy storage and conversion applications. Further the critical assessment and current problems of SURMOFs have been briefly discussed to explore the future opportunities in SURMOFs for energy storage and conversion applications.

Tytuł:: The Obligation of Strategic Gas Storage Introduced in Poland as an Example of a Public Service Obligation Relating to Supply Security: A Question of Compliance with European Law
Autorzy:: Mordwa, Maria
Wydawca:: Center for Antitrust and Regulatory Studies
Opis:: Michał Mijal
This paper presents the system for the strategic storage of gas imposed by the Act on Fuel Reserves and evaluates its compliance with the relevant provisions of EU law, in particular the so-called 2nd and 3rd Internal Energy Market Packages. Unlike the case of legislation on strategic oil stocks, EU legislation on gas does not impose on Member States any obligation to maintain strategic reserves of gas. Furthermore, Member States are obliged to implement common rules establishing an internal market in natural gas including Third Party Access (TPA) to storage facilities. However, Member States are allowed to impose on undertakings operating in the gas sector, in the general economic interest, public service obligations which may relate to supply security, and EU law recognizes the contribution of gas storage to the security of supply. Thus, the objective of this article is to evaluate whether the Act on Fuel Reserves as well as the amendments to it proposed by the Polish Ministry of the Economy are in line with the relevant provisions of EU law. The analysis includes the position of the Court of Justice presented in several judgements as regards the concept of public service obligations.

Opis:: This work describes the use of commercially available starch as a binder for the preparation of conductive glue and electrode materials. It is demonstrated that starch can be successfully implemented as a binder in energy storage systems with non-aqueous electrolytes. These devices are characterized by a stable cycle life (for 50,000 cycles) at a nominal voltage of 2.5 V. Moreover, the use of starch-based conductive glue improves the electrochemical performance, especially reducing the internal resistance of the device. Starch-bound electrodes display lower equivalent distributed resistance (EDR) values than electrodes using carboxymethylcellulose (CMC) as the binder. This is due to the noticeably lower pore clogging by starch. An electric double-layer capacitor (EDLC) in organic electrolyte (1 mol L−1 TEABF4 in ACN) at a nominal voltage of 2.5 V can reach a specific power and energy of 100 kW kg−1 and 12 Wh kg −1, respectively. This study shows that starch-based conductive glues and electrode materials can be incorporated in EDLC systems.

Opis:: Sylwia Chudy
The aim of this study was to determine the effect of the duration of vacuum storage on oxidation of cholesterol and fatty acids, as well as on sensory properties of dried milk and egg mixed powder in comparison with whole milk powder and egg powder. Determination of the contents of fat and water, peroxide value and sensory evaluation were done according to American Oil Chemists’ Society and ISO official methods. The application of vacuum packaging did not protect powders against progressing changes in lipids. Composition of the powders determined their oxidation stability and formation of oxycholesterols, hydroperoxides, the value of the browning index, as well as sensory properties. After production and during storage of mixed powders, the evaluated indeces had values between those recorded for milk powder and egg powder. On the basis of these findings, it can be concluded that the analysed milk-egg powder retained its good sensory attributes up to the 12th month of storage in spite of physical and chemical changes taking place.

Wydawca:: World Congress on Education (WCE-2015)
Opis:: The paper outlines the basic tenets of the information storage and processing theory, comparing it to other cognitive development theories. The authors present results of studies regarding the phenomenon of intelligence and applies them to characterize intellectual processes as they occur in children with significant or severe aural impairments. The presented research lasted for approximately one year and was based on a series of tests, applying the deductive and autocreative learning model as well as the assumption that assimilation of information may be described in probabilistic terms. Test results and conclusions enable the authors to formally assess that revalidation activities based upon information processing theories may significantly improve the effectiveness of teaching. The presented research proves also that aurally impaired children possess similar mental skills as their unimpaired counterparts.

Opis:: Edible insects are more and more widely researched and presented as a good source of nutrients. Among the available raw materials, cricket powder (CP), obtained from roasted and crushed crickets, deserves attention because it can be used as an ingredient in many food products. The aim of this study was to determine the effect of CP addition on the physical and sensory properties of extruded corn snacks. In the extrusion process, five variants of corn snacks were produced with 2%, 4%, 6%, and 8% additions of CP, and with 8% CP and 2% baking powder. Snacks without CP addition were used as a control (R). The study also evaluated the storage life of the manufactured snack products based on their sorption properties. It was found that increasing the CP content in snacks has a significant effect on their characteristics, with a lower expansion ratio as the result of the higher CP content in the extrudates. CP increased the solubility and decreased the water absorption of the snacks. Color changes were also observed in the produced snacks. The more CP in the recipe, the darker the end product. In addition, the color parameters a* and b* were shifted towards red and blue in cross-sections of snacks with higher percentages of CP. According to the sensory analysis, CP additions up to 6% allow for obtaining sensory-attractive snacks. Statistical analysis of the results showed that the snack parameters, expansion ratio, and water absorption index are of the greatest importance for sensory acceptance. Therefore, when planning the incorporation of CP into this type of product, special attention should be paid to obtaining extrudates with appropriate parameters.

Tytuł:: Different views on tree interception process and its determinants
Autorzy:: Klamerus-Iwan, Anna
Wydawca:: Instytut Badawczy Leśnictwa
Opis:: Przemysław Szmit
The subject of the study is the process of interception by plants defined as the process of retaining rainfall water on plant surface, counting retention by individual plant parts or the vegetation cover as the whole. In the quantitative approach, interception capability of plants may be compared to a reservoir, the capacity of which is determined mostly by the surface of plants. Among many approaches to describe interception processes, a lot of attention has been focused on research concerning the forest vegetation with reference to atmosphere – forest stand – soil balance. Hence, in the present paper interception issues are addressed in view of forest ecosystems. The emphasis is also put on the methods and results of studies carried out under laboratory conditions. . Up-to-date literature on interception is abundant. The authors tackling this issue regularly define their own variable and complex sets of terms. This paper is an attempt to review and organize knowledge presented in existing literature on the subject.

Tytuł:: Hydrological properties of bark of selected forest tree species. Part 2: Interspecific variability of bark water storage capacity
Autorzy:: Ilek, Anna

Wydawca:: Committee on Forestry Sciences and Wood Technology of the Polish Academy of Sciences and the Forest Research Institute in Sekocin Stary
Opis:: The subject of the present research is the water storage capacity of bark of seven forest tree species: Pinus sylvestris L., Larix decidua Mill., Abies alba Mill., Pinus sylvestris L., Quercus robur L., Betula pendula Ehrh. and Fagus sylvatica L. The aim of the research is to demonstrate differences in the formation of bark water storage capacity between species and to identify factors influencing the hydrological properties of bark. The maximum water storage capacity of bark was determined under laboratory conditions by performing a series of experiments simulating rainfall and by immersing bark samples in containers filled with water. After each single experiment, the bark samples were subjected to gravity filtration in a desiccator partially filled with water. The experiments lasted from 1084 to 1389 hours, depending on the bark sample. In all the studied species, bark sampled from the thinnest trees is characterized by the highest water storage capacity expressed in mm H2O · cm-3, while bark sampled from the thickest trees – by the lowest capacity. On the other hand, bark sampled from the thickest trees is characterized by the highest water storage capacity expressed in H2O · cm-2 whereas bark from the thinnest trees – by the lowest capacity. In most species tested, as the tree thickness and thus the bark thickness and the coefficient of development of the interception surface of bark increase, the sorption properties of the bark decrease with bark depth, and the main role in water retention is played by the outer bark surface. The bark of European beech is an exception because of the smallest degree of surface development and because the dominant process is the absorption of water. When examining the hydrological properties of bark and calculating its parameters, one needs to take into account the actual surface of the bark of trees. Disregarding the actual bark surface may lead to significant errors in the interpretation of research results.
