Published: December 2021

The current issues of climate change and high freshwater demand worldwide have promoted the implementation of wastewater reclamation technologies. This study aims to review the efficiency of the dissolved air flotation (DAF) technique in a wide variety of applications in the agricultural, industrial, domestic, and municipal sectors, which have high freshwater consumption worldwide. We made a systematic review of the DAF technique in wastewater treatment in 2015-2021. We reviewed six indexed databases and governmental statistical reports; we used the keywords: dissolved air flotation, microbubbles, wastewater treatment, and the main operating and design parameters involved in the effectiveness of the flotation process. Additionally, we conducted a review of the most common synthetic coagulant studies used with DAF, as well as natural coagulants that promise to mitigate current climate change. Finally, we discussed advantages, disadvantages, and potential future studies. DAF to have considerable potential for wastewater treatment, as well as for waste utilization. The generation of large quantities of DAF sludge is a breakthrough for clean energy production, as it allows the use of this waste for biogas production.

Latar Belakang. Iodium merupakan mikronutrien penting terutama bagi perkembangan otak janin dan anak. Iodium berperan untuk proses pertumbuhan dan perkembangan sebagian besar organ terutama otak. Konsumsi iodium yang rendah dalam jangka panjang merupakan salah satu faktor yang dapat menyebabkan gangguan akibat kekurangan iodium (GAKI). Tingkat pengetahuan mengenai GAKI dan garam beriodium berpengaruh terhadap ketersediaan dan praktik penggunaan garam beriodium. Pemerintah telah mengupayakan penanggulangan GAKI melalui fortifikasi garam dengan iodium. Tujuan. Penelitian ini bertujuan untuk menganalisis pengetahuan ibu tentang iodium dengan ketersediaan garam beriodium di rumah tangga dan faktor yang memengaruhinya. Metode. Penelitian ini merupakan penelitian cross-sectional. Data diambil dari 198 rumah tangga menggunakan teknik proportional stratified random sampling. Penilaian pengetahuan ibu dilakukan dengan menggunakan kuesioner dalam bentuk pertanyaan tertutup. Sementara itu, penilaian ketersediaan garam diperoleh dengan pengujian kandungan iodium (KIO3). Uji statistik yang digunakan adalah chi-square test/fisher’s exact test dan Mann Whitney U/Kruskal Wallis untuk mengetahui hubungan antar variabel. Hasil. Sebagian besar responden tinggal di daerah dataran tinggi (74,2%), berpendidikan SD (47,5%) dan bekerja sebagai petani (41,4%). Karakteristik lokasi geografi tempat tinggal responden berhubungan dengan pengetahuan responden mengenai GAKI serta dampak dan faktor risiko GAKI (p=0,023 dan p<0,001), sedangkan pekerjaan responden berhubungan dengan pengetahuan mengenai dampak dan faktor risiko GAKI (p=0,020). Tidak ada hubungan antara pengetahuan dengan pemenuhan syarat mutu kandungan KIO3 pada garam yang digunakan di rumah tangga. Namun ada kecenderungan responden yang mempunyai garam dengan KIO3 sesuai, lebih banyak pada responden dengan pengetahuan yang baik. Kesimpulan. Responden dengan pengetahuan baik lebih banyak yang memiliki garam dengan kadar iodium sesuai standar. Perlu adanya program edukasi mengenai GAKI, penggunaan dan penyimpanan garam beriodium, serta faktor penyebab penurunan kualitas garam di rumah tangga.

Građevni i urbanistički propisi u Hrvatskoj od 1956. do 1971. godine
Authors: Kahle Darko
Published: December 2021

U članku se opisuju i komparativno analiziraju građevni i urbanistički propisi u Hrvatskoj od 1956. do 1971., kad je načelno dovršen zakonodavni okvir jugoslavenskih i hrvatskih građevnih propisa. Analizirani propisi, koji su prvi put bili stručno publicirani u repetitoriju 1956. godine, ambivalentno su nastajali na službenoj negaciji građevnoga zakonodavstva Kraljevine Jugoslavije 1946. i neslužbenom korištenju većine ukinutih propisa sve do kraja 1960-ih. Kolokvijalno poznati pod suvremenim pojmom građevinska regulativa, analizirani propisi pokazuju određenu tehničku kompetentnost u člancima koji nisu zadirali u socijalističko društveno uređenje, ali i potpunu ovisnost o tom uređenju u ostalim paragrafima, poput procedura upravnoga
postupka ili toleriranja bespravne izgradnje.
Javna polemika Stipe Šuvara i Šime Đodana iz 1969. kao primjer borbe ideja u (trans)nacionalnom kontekstu
Authors: Badurina Marino
Published: December 2021

U radu se razmatraju povod, tijek i sadržaj intelektualne i političke debate između Stipe Šuvara i Šime Đodana koja se odvijala tijekom 1969.,
u uvjetima društveno-političkih, kulturnih i ekonomskih previranja u tadašnjoj socijalističkoj Hrvatskoj i Jugoslaviji. Glavno pitanje koje se eksplicitno i implicitno provlačilo kroz debatu bilo je: „Je li Hrvatska u Jugoslaviji eksploatirana?” No ta je rasprava bila višeslojna
i kompleksnija od toga. U njoj su se autori dotakli i međuodnosa nacionalizma i međunarodne ekonomske integracije unutar Jugoslavije, kao
i integracije Jugoslavije sa svijetom, odnosa ekonomije i kulture, emocionalnih i racionalnih argumenata u političkoj i ekonomskoj sferi, nacionalizma i demografije, modernizacije i nacionalne emancipacije, međudjelovanja procesa u istočnom, socijalističkom lageru i na Zapadu te
konsekvencija koje bi Jugoslavija i jugoslavensko društvo iz toga trebali povlačiti. U takvu složenijem iščitavanju njihove suprotstavljene pozicije (borba ideja) ne mogu se svoditi na dihotomiju socijalizam – nacionalizam i hrvatstvo – jugoslavenstvo.

Authors: Krawiec Monika , Furman Rafał
Published: December 2021

Celem pracy była identyfikacja punktów zwrotnych cen ropy naftowej w latach 2015 – 2019, do czego zastosowano test Perrona. Następnie podjęto próbę wskazania wydarzeń o charakterze geopolitycznym, które mogły być przyczyną istotnych zmian w strukturze trendu. Wykorzystano w tym celu, publikowane na portalach biznesowych, komentarze analityków oraz raporty surowcowe. Na tej podstawie oceniono, że w większości przypadków na notowania ropy naftowej w badanym okresie najbardziej wpływały problemy z nadwyżką podaży ropy naftowej w Stanach Zjednoczonych. Raporty informujące o zwiększającej się liczbie funkcjonujących platform wiertniczych w Ameryce Północnej oraz niski popyt na rynku paliwowym często powodowały długotrwałe obniżki cen na giełdach New York Mercantile Exchange (NYMEX) i Intercontinental Exchange (ICE).

Authors: Belic Dragoljub , Vojnovic Mirjana , Ristic Miroslav , Urbain Xavier , Defrance Pierre
Published: December 2021

Rate coefficients for electron-impact dissociation of O3+ to the O+ and O2+
fragments are calculated for the new, recommended cross section data set and
for various collisional conditions. Two sets of the cross section data,
measured recently by different experimental groups, are used. These cross
sections differ significantly with each other, but are renormalized and
optimized to the coherent data base. Rate coefficients for the ozone cation
fragmentation are determined using the Maxwellian and the non-thermal
electron energy distribution functions (EEDF). In the case of Maxwellian
distribution, mean electron energies cover the range from zero up to 2 keV.
Non-thermal electron energy distribution functions are adopted from the
recent electron observations by the 3-D plasma and energetic particles
experiment on the WIND spacecraft. The non-thermal rates are evaluated for
the mean electron energies from 4 to 80 eV. The role of the possible
contribution of electron-impact dissociation of O3+ to the Ozone layer
depletion has been emphasized.

A Unique 14th Century Seal Matrix from Giebło, Zawiercie District
Authors: Krudysz Leszek
Published: December 2021

A unique lead seal-matrix with majuscule legend: LUCIANI PRESBITERI belonging to a priest was found by the Romanesque castle church in Giebło. The name of its owner is mentioned in written sources from the years 1325–1327 as plebanus ecclesie de Kebel. As PRESBITER he probably didn’t enjoy all privileges that the collator usually bestows on a parish priest on his property. Possibly for that reason he had his matrix made in an easy-to-process material, infrequently used for such objects in this part of Europe. The use of this raw material suggests someone who tried avoid the high costs of making the item. Special attention is merited by the composition of a fleur-de-lis crowned with the cross engraved on the seal face that resembles a heraldic device. The repetition of a schematic lily flower on the reverse of the matrix shows the special importance of this sign (identified in medieval time with the Blessed Virgin Mary); this symbol was treated in this way by, for example, Cistercians. By presenting his name in the company of these symbols, Lucianus gave his seal strength and credibility.

Grunnskolelærere i musikk og deres kompetanse
Authors: Nielsen Siw Graabræk , Karlsen Sidsel
Published: December 2021

I denne artikkelen diskuteres kompetansen til lærere som underviser i musikk i den norske grunnskolen. Utgangspunktet er data hentet fra en spørreundersøkelse blant 293 lærere over hele landet. Undersøkelsen bygger på et Bourdieu-inspirert teoretisk rammeverk der det å ha tilgang til rike musikalsk-kulturelle ressurser forstås som potensielt utvidende for elevenes musikkrelaterte kapital på tvers av sosiale og kulturelle skillelinjer. Tidligere forskning viser at høy grad av faglig spesialisering hos musikklærerne er knyttet til mulighetene for å iverksette et rikt musikkfag for elevene. Lærerkompetansen i musikk i den norske grunnskolen har generelt blitt forstått som lav, men resultatene fra den rapporterte undersøkelsen viser et mer komplekst bilde av situasjonen. 
English abstract
English title: The competence of compulsory school music teachers. What is the situation in the Norwegian context?
This article discusses the competence of teachers teaching music in Norwegian compulsory education. It takes as its point of departure data gathered through a survey among 293 teachers located across the country. The theoretical framework is Bourdieu-inspired and emphasises access to rich musical and cultural resources as potentially enhancing for students’ music-related capital across social and cultural divides. Previous research shows that a high degree of subject-specific specialisation among music teachers is coupled with the possibilities of implementing a rich music subject for the students. While teacher competence in music in Norway has generally been understood as low, the findings from the survey reported here show a more complex picture of the situation.

Authors: Knigge Jens , Danbolt Ingrid , Hagen Liv Anna , Haukenes Siri
Published: December 2021

This study investigates the current situation regarding singing in Norwegian kindergartens. More specifically, how often kindergartens offer singing possibilities to children, in what situations singing is embedded, how valued singing is in such institutions, what singing methods and repertoires the teachers use, and whether teachers have certain underlying goals and beliefs connected to their use of singing. Furthermore, we are interested in whether there are contextual factors that influence the singing practice of a kindergarten/teacher. This exploratory cross-sectional study uses a webbased questionnaire, and the sample consists of 660 Norwegian kindergarten teachers. The statistical analyses cover standard descriptive and inferential statistics. The study’s main findings are as follows: (1) singing is highly valued in most kindergartens; (2) singing is done “very often” in most kindergartens, and the majority of teachers report that they sing with the children daily in a large variety of situations and using mainly Norwegian songs – however, the actual frequency and amount of singing depends on various factors; (3) one of the most important factors regarding singing praxis is musical expertise of teachers, regarding which most teachers rate themselves as below the population average; (4) the teachers mainly sing unaccompanied with the children; (5) they learn new songs mainly through streaming services; and (6) the teachers assume that singing leads to especially positive psychological, social, and cognitive effects on children.

Authors: Osmanović Zajić Jelena , Mamutović Anastasija , Maksimović Jelena
Published: December 2021

The challenges of contemporary education and teaching profession have resulted in an increased demand for the appropriate professional advancement and practice-based research. The action research is an approach that encourages teachers to manage and control their own work. This research was conducted with the purpose of being primarily beneficial for primary and secondary school teachers. The empirical research presented in this paper was based on the factor analysis, by which the research factors were extracted, as well as on the examination of the teachers’ attitudes towards methodological education, cognition and metacognition in teaching, reflexive practice, science education and lifelong learning in the context of the action research. The method used was descriptive together with the scaling technique and the five-level Likert scale (AISE) consisting of 29 items. The research was realized in 2020, and then retested in 2021. The number of 1021 teachers from the Republic of Serbia participated in this research. The research results showed statistically significant differences in the respondents’ responses related to the independent research variables: education cycle, teaching experience and the number of professional development seminars attended. The significance of action researches is reflected in the fact that the problems are resolved by the teachers themselves, not the scholars or academics who are not directly involved in teaching. Therefore, this research contributes to a greater motivation and support of teachers to raise their classroom activities and accomplishments to the level of a scientific research.

Choosing the technology for the construction of buildings in the Arctic conditions is stipulated by two important factors, namely, the remoteness of the facilities and the short period of the summer season, which actualizes the problem of reducing the mass of structures and making shorter the construction work duration. In addition, one should keep in mind other important factors, such as permafrost, strong winds and low temperatures. Such conditions of construction necessitate the use of building technologies and space-planning solutions using light metal structures and mineral wool slabs, as well as sandwich-type laminated panels. The unified nomenclature, compactness and relative lightness of the parts ensure high efficiency of construction in the remote territories of the Arctic zone of the Russian Federation. The first experimental construction experience in the Arctic has shown not only the comfort of space-planning solutions, but also the manufacturability of installation of load-bearing and enclosing structures of the erected residential and administrative complexes of the Arctic Trefoil type. The block-modular technology for the construction of dormitory buildings in the village of Tiksi (Yakutia), as well as the technology for the construction of buildings of the production and logistics complex «Arkhangelsk», erected using light steel structures, sandwich type panels and other pre-fabricated structures. A comparison analysis of pre-fabricated building systems according to the criterion of manufacturability has been carried out. There are proposed some fundamental solutions aimed at improving the installation technology of buildings in the Arctic conditions.

Published: December 2021

Welding industry is one of the leaders in the field of investments in the development of technologies and innovations aimed at ensuring functional cost-effectiveness, improving safety and speed of movement in the digital age. Ensuring the reliability and safety of the railway tracks requires the development of new scientific approaches to the use of welding technologies in the construction and operation of a high-speed railway. The main criterion for evaluating efficiency of the new approaches is the quality of the resulting welded joints and the productivity of the welding processes used. Rail connections should be made in such a way from a technical point of view that there are no restrictions during operation, the service life of the rails is not reduced, the percentage of defects does not increase, and the noise level is within the normal limits. The purpose of the study is to substantiate the cost-effectiveness and safety of the introduction of new contact welding technologies in Russia. Technical and economic analysis of welding methods is given, including using the rail welding machines — a new generation of equipment for the contact butt welding of high-strength rails during the construction and reconstruction of a high-speed railway. The Up-to-date technologies are based on the process of contact welding by pulsating reflow, on the one hand ensuring high productivity of the process, and on the other — reducing the influence of the human factor on it. This is achieved through a set of options for controlling the welding process, with online monitoring of the operational characteristics, with the software for storage and the possibility of using robotic welding in the future in the field of digital doubles and processing archived data based on the artificial intelligence as part of the implementation of Smart City projects.

The article is devoted to the study and development of the components of gas generator compositions based on the ammonium nitrate to improve safety of blasting operations. This is primarily due to the low cost of ammonium nitrate, low sensitivity to mechanical and detonation effects and a significantly lower content of harmful compounds in the combustion products compared to the analogues. PA-4 aluminum powder was used as fuel, carbon black powder — as a gas-forming agent. The effect was studied concerning different amounts of aluminum powder on the combustion characteristics of a gas generator composition based on the ammonium nitrate. Calculated and experimental data showed that it is unreasonable to introduce more than 5 % of aluminum into the composition. According to the results of the conducted study, a gas generator composition based on the ammonium nitrate was developed to increase blasting operations efficiency and safety. Laboratory and polygon studies confirmed the efficiency and safety of using gas generator compositions at the destruction of stone. Destruction of the stone occurred without scattering of individual fragments, formation, and propagation of an air shock wave. Thus, the urgent task is to ensure blasting operations safety using gas generator compositions, which will allow to eliminate the formation of harmful, toxic gases and the high explosive effect.

The subject of the study are the components of the corporate safety culture of a construction enterprise. The analysis was conducted related to the state of occupational safety, elements of its management system at one of the construction and installation trusts typical for the oil and gas industry (Surgut Construction and Installation Trust № 1 of «Surgutneftegas» PJSC). The existing problems in the field of occupational safety at the enterprise are considered, the level of maturity of the safety culture, the reasons for the deviant behavior of employees are determined. According to the Bradley Scale using the company DuPont Sustainable Solutions methodology, the enterprise is in a transition stage from a «dependent» to an «independent level». A number of the documents was developed and presented as a component of the safety culture elements. The package of documents is prepared in the form of an information notebook containing: «An act of the refusal to perform the work in case of danger to the life and health of an employee», «Procedure for the actions of an employee in case of danger to his life and health during the performance of work», «The procedure for the actions of engineering and technical employee in case of refusal of an employee to perform the work and execution of the «Act of refusal», «The list of violations of the occupational safety requirements, in the presence of which an employee has the right to refuse to perform the work in case of danger to his life and health». The algorithm of actions proposed in the prepared documents will allow the employees to refuse to perform the work in case of disputable situations on the legal grounds if there is a danger to their life and health. The recommendations presented in the paper will allow to create prerequisites for improving the level of safety culture, enhancing the teamwork in safety issues, and, in the future, the formation of an interdependent level of safety culture.

Aim: To evaluate the influence of L-carnitine on inflammatory markers and indicators of endothelial function in patients with acute myocardial infarction without the Q wave.Materials and Methods: 40 patients with verified diagnosis of AMI without Q-wave. All the patients were matched by sex, age, weight and duration of the underlying disease. The patients were randomized into 2 groups. The first group ofpatients were on a standard basic therapy and additionally administered L- carnitine at a dose 5g/day, II- group consisted of patients who did not receive drugs with metabolic action. In dynamics (on the 1st and 10th day of the treatment) the parameters of endothelium vasodilation and markers of inflammation were evaluated.Results: On the background of the basic therapy in both groups an improvement in endothelial function resulting in an increase of brachial artery diameter was observed. However, the L- carnitine vasodilator effect was more pronounced and persistent as compared to group II. In the dynamics, CRP levels and plasma fibrinogen were more pronounced in the Ist group.
