Published: May 2021

Abstract
Pomace is the solid residue by-product resulting from the extraction of olive oil. Their high content of organic compounds gives them the possibility of being used also as green manure. We have tried this amendment approach on two varieties of cherry grown in the Tlemcen region. The Sunburst and the Black Bigarreau. Its use in combination with N.P.K fertilizers increases the carbon content of the soil, boosts the formation of May bouquets, and improves the water-holding capacity of the clay-humic complex. The results of this study showed that olive pomace used as a fertilizer, alone or in combination with N.P.K mineral fertilizers creates an advantage on the phenological and biochemical aspect, especially on the Black Bigarreau variety.
Resource Integration, Value Co-Creation, and Service-dominant Logic in Music Marketing: The Case of the TikTok Platform
Authors: Toscher Benjamin 
Published: May 2021

Abstract
It is a fact that the past research has explored service-dominant logic (S-D logic) and value co-creation in music marketing (Choi & Burnes 2013; Gamble & Gilmorex 2013; Gamble 2018; Saragih 2019), yet a key aspect of S-D logic, namely resource integration, is an unexplored territory and a promising phenomenon of study. A scattering of evidence demonstrates how actors, whether individuals or organisations, in the music industry are making value propositions and providing operand resources to users of platforms (Poell, Nieborg, & Van Dijck 2019), which may result in resource integration and commercial success at a quick pace and on a global scale. Using secondary data in an archival research approach (Welch 2000), this paper examines TikTok, a rapidly growing platform where users integrate short (e.g., under 15 s) clips of commercial music into user generated video content in which users dance to, lip-sync with, accept social challenges, integrate hashtags and create memes based on musical content. Further, there is a discussion on evidence about how music is being used by actors on TikTok in order to argue that (a) S-D logic (Vargo & Lusch 2016) is an insightful perspective through which one is able to understand music marketing; (b) music providers essentially make value propositions with their music that other actors, such as music consumers, can integrate into their lives through platforms like TikTok; (c) changes in technology affect such resource integration and how actors in the music industry can adapt to such change; (d) value-in-social-context (Edvardsson, Tronvoll, & Gruber 2010) is a driver of resource integration by users on the platform; and (e) this example of value created by users on TikTok is just one example of the many types of value which guide action and interaction on today’s music platforms. The discussion and analysis is concluded with several implications for research and practice.
Co-constitutive complexityUnpacking Google’s privacy policy and terms of service post-GDPR
Authors: Valtysson Bjarki , Jørgensen Rikke Frank , Munkholm Johan Lau 
Published: May 2021

Abstract
Google is the gateway to the Internet for billions of people. However, to use Google’s multiple platforms and services, users must accept Google’s terms. With the advent of the EU’s GDPR (General Data Protection Regulation), Google made significant changes to these terms. In this article, we scrutinise the intertextual relations between Google’s privacy policies and terms of service (ToS) and the GDPR – and the discursive co-constitutive complexity within and between these frameworks. We argue that the material and communicative articulation of Google’s privacy policies and ToS should be understood as deliberative data politics delimiting users’ agency, consent, and privacy. Furthermore, we emphasise complexity and the demands of reducing complexity as two opposing dynamics. While the GDPR required Google to make its terms and policies clearer and more understandable, ironically, in the process of accommodating GDPR’s demand of increased transparency, the discursive complexity of Google’s policies has in fact increased.
The effect of soil conditioners on the content of soluble carbohydrates, digestible protein and the carbohydrate–protein ratio in Lolium perenne and Dactylis glomerata

Published: May 2021

Abstract
A three-year field experiment (52.169°N, 22.280°E), in which each treatment was replicated three times, was set up in a randomised split-plot design in the autumn of 2011. The main experimental factors were soil conditioners with the trade names such as UGmax, Eko-Użyźniacz and Humus Active Papka, which were applied on their own and with mineral fertilisers. They were applied to the soil with two forage grasses: the Bora variety of Dactylis glomerata and Lolium perenne of the Info variety. The results were processed statistically with the multi-factor analysis of variance with a significance level of P≤0.05, whereas the differences between means were verified with Tukey’s test. The Statistica 12 program was used to do all the calculations. Compared to the control, soil conditioners (UGmax, Humus Active and Eko-Użyźniacz) did not reduce carbohydrate content in grass significantly. This proves that they can be applied to grass. Combination of mineral fertilisers with soil conditioners, relative to the control, resulted in about 15% increase in digestible protein content. Comparing all the plots, without the control, the ratio of non-structural carbohydrates to protein was the most favourable in the grass from plots where UGmax or nitrogen-phosphorus-potassium (NPK) fertiliser or a combination of both was applied.
Greenhouse gas emission from motor vehicles in Poland in 2015
Authors: Chłopek Zdzisław , Olecka Anna , Szczepański Krystian 
Published: May 2021

Abstract
The article presents the results of the inventory of greenhouse gas emissions from motor vehicles in Poland in 2015. The inventory was developed in accordance with the applicable guidelines for the annual greenhouse gas emission inventory (Decision 24/CP.19 of the Conference of the Parties to the United Nations Framework Convention on Climate Change) by the National Centre for Emissions Management and Balancing (KOBiZE) at the Institute of Environmental Protection – the National Research Institute. The national annual gas emissions from road transport are presented, including: carbon dioxide, methane and nitrous oxide along with emissions of the above gases converted into carbon dioxide equivalents. Carbon dioxide makes up the largest share in carbon dioxide emissions. This is particularly evident in the case of road transport – the emission of gases other than carbon dioxide (methane and nitrous oxide) is several orders of magnitude lower than the emission of carbon dioxide. Carbon dioxide emissions from road transport account currently for approximately 14% of the total carbon dioxide emission in Poland.
The role and significance of stingless bees (Hymenoptera: Apiformes: Meliponini) in the natural environment
Authors: Bąk-Badowska Jolanta , Żeber-Dzikowska Ilona , Gworek Barbara , Kacprzyk Wanda , Chmielewski Jarosław 
Published: May 2021

Abstract
This article refers to the biology and ecology of stingless bees (Meliponini), living in tropical and subtropical areas. Similar to honey bees (Apis mellifera), stingless bees (Meliponini) belong to the category of proper social insects and are at the highest level of social development. This group of insects comprises about 500 species and they are the most common bees pollinating the native plants in many tropical areas. Families of stingless bees are usually quite numerous, reaching up to 100,000 individuals. They are characterised by polymorphism, age polyethism and perennialism. This article presents the structural complexity of natural nesting of these tropical insects and their ability to settle in artificial nest traps. The main significance of stingless bees for humans is their role in the natural environment as pollinators, which is an essential factor influencing biodiversity.
Indicators of peat soil degradation in the Biebrza valley, Poland
Authors: Sienkiewicz Jadwiga , Porębska Grażyna , Ostrowska Apolonia , Gozdowski Dariusz 
Published: May 2021

Abstract
Peat mineralisation leads to net loss of CO2 to the atmosphere, as well as to release of other elements from the decomposed soil organic matter (SOM) to groundwater. This results in the degradation of peat soils and the ecosystems they support. Here we evaluated the practical indicatory suitability of the existing and proposed new indices for the assessment of peat soil degradation in the Biebrza river valley encompassing, unique on European scale, peatland ecosystems. We studied relationships between soil organic carbon (SOC) and total nitrogen (Ntot), dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) in a series of degraded peat soils in the Biebrza valley. Samples were taken from soils developed on peat deposits that varied in thickness and the degree of peat decomposition, from undegraded to highly mineralised peats. The relationships between changes in the SOC content and changes in the values of the remaining variables (SOM, Ntot, DOC, DON, C/N ratio), were statistically tested. Linear and non-linear regressions were used to establish the relationships amongst the variables examined. The losses of soil C and N occur independently and differ between stages of peat soil mineralisation. From our study, it results that the peat mineralisation intensity may be estimated based on the loss of SOC. We found that 1% loss of SOC corresponded to 1.028% loss of SOM, regardless of the degree of peat soil mineralisation, whereas SOM solubility, measured by the content of DOC, varied based on the intensity of peat soil mineralisation. The content of DOC decreased with the decrease in the SOC content, whereas the DOC/ SOC ratio increased depending on the intensity of peat decomposition. The C/N ratio is not a reliable indicator of peat mineralisation, because its values are driven not only by the nitrogen natively present in peat soils but also by nitrogen from external sources. The contents of SOC and Ntot did not decrease uniformly during peat decomposition because C and N show various mobility in the processes of SOM mineralisation. We found that the DOC/SOC ratio was most indicative of peat soil mineralisation intensity.

Published: May 2021

Abstract
The amount of used and worn out tires around the world reaches about 10 million tons. Rubber introduction to the environment in this shape is connected with its pollution, caused by tires’ chemical composition, which, apart from synthetic and natural rubber, contain soot as a filler, plasticizers having some amounts of polycyclic aromatic hydrocarbons and helping substances: activators, accelerator of vulcanization, cross-link means and homogenizers. The most important activator is zinc oxide. The aim of the conducted studies was to determine the influence of rubber rag added to the subsoil on the amount of yield, physiological state and the amount of taken zinc by maize (Zea mays). It was found that the rubber rag introduced into the soil caused an increase in the yield of maize and the plants growing on the soil with the highest amount of rubber rag showing higher efficiency photosynthetic apparatus than others. The zinc content in the aboveground parts of maize increased with the increase of rubber rag in the soil.
Innovative process solutions in the field of water decarbonisation as an element of integrated management in environmental protection – A case study
Authors: Kamiński Arkadiusz , Nadrowski Michał 
Published: May 2021

Abstract
Most waters in Poland are classified as medium or very hard. In case of industrial waters, their chemical composition and physical parameters play an essential role. The water ought to be soft and should not contain dissolved salts and gases. This water, which has not undergone a softening process, may cause damage to heating devices and boiler scale within a few years. Therefore, water softening is mainly used for heating and energy purposes. However, an important issue is technological processes in which water is used both as a product additive or as an agent in exchange of heat and mass [Reference Document…2001; Nawrocki, Biłozor 2000; Kiedryńska, Papciak, Granops 2006; Biłozor 2012].
The aim of the work was to determine the effect of changes in the proportion of decarbonised water in the process water stream on its parameters (oxidability, general hardness) and parameters of cooling water in water cycles. The possibility of limiting the consumption of raw water to the processes carried out on the premises of the plant and the possibilities of improving energy efficiency in the area of water and wastewater management with a variable stream of decarbonised water in the technological water was checked. It was found that the increase in the share of decarbonised water in the technological and cooling water stream is important in the implementation of process solutions in this area and has a positive effect on reducing costs related to the operational functioning of the water and wastewater management area.

Published: May 2021

Abstract

Aim. The aim of this paper is to present alternative ways for women with uterine factor infertility to achieve motherhood.

Material and methods. Analysis of professional literature including the issues of surrogate motherhood, uterine transplantation and ectogenesis.

Results. The infertility caused by uterine factor affects 3-5% of women in the world. There are also women who wish to conceive a baby out of their own genetic material, despite having a structurally abnormal uterus or lacking this organ altogether. Due to considerable advancements in reproductive medicine, the needs of such women can now be met via extracorporeal fertilisation and embryo implantation into the uterine cavity of another woman – surrogacy, or in special cases, via uterus transplantation. Another controversial concept is ectogenesis, i.e. technology which would allow for the growth of human embryos outside the mother’s body in an artificial uterus. The surrogate is considered when treatment and other reproduction methods have not worked well. This procedure is legal and accepted in some countries, while in others it is strongly opposed.

Conclusions. There is growing demand for accurate and modern diagnostic and therapeutic methods allowing for successful reproduction. The proposed solutions may seem unreal, but the results of the research carried out to embody them seem to be promising.
