Green concrete is a form of eco-friendly composite material that is manufactured using waste material as one of its components. Guinea corn husk ash (GCHA) and waste metalized plastic (WMP) are all by-products that are nuisance to the environment. It is important to understand their influence on workability and mechanical properties of self-compacting concrete (SCC). In this study, the influence of waste metalized plastic fibre (WMPF) and Guinea corn husk ash (GCHA) on workability and mechanical properties of SCC was investigated. The concrete was designed to attain a characteristic strength of 40 N/mm2. The chemical composition of the GCHA was determined by X-Ray Fluorescence (XRF) method. Properties studied include slump flow test on fresh concrete in addition to compressive strength, direct tensile strength and microstructure of the hardened concrete. Seven concrete mixtures containing 0% - 1.5% WMPF of size 2mm width by 20mm length were cast. A second batch of concrete mixes containing the same fibre dosages and 5% GCHA as substitute of Ordinary Portland cement (OPC) were also cast. All concrete cast were cured and tested for 7-days, 28-days and 91-days for both compressive and direct tensile strengths. The result show that there was a reduction of slump flow due to inclusion of WMPF and GCHA in all the concrete mixes. Also, the compressive strength of both mixes reduced with the increase in the fibre content. There was an enhancement of the direct tensile strength due to inclusion of WMPF. The compressive strength of 5% GCHA-based concrete reduced at 7 and 28 days curing period and witnessed a high gain of strength at 91-days curing period. In conclusion, the compressive strength of both OPC-based and 5% GCHA-based concretes without fibre were found to be 52.42 N/mm2 and 58.27 N/mm2 respectively at 91 days of curing.

The Renewal of Traditions and Their Transformation Using an Example of Whitsuntide Ceremonies in Moravia and Silesia
Authors:   Národní ústav lidové kultury, Blažek Jan
Published: June 2024

The ceremonial chase after the king and the processions of young girls called Little Queens began to disappear from the customary year in Moravia and Silesia in the mid-nineteenth century. Yet these rituals attracted the interest of the prominent ethnographers of the late nineteenth century – František Bartoš, Čeněk Zíbrt and Lucie Bakešová, and in the twentieth century, of e.g. Václav Frolec who studied the Ride of the Kings, and Zdenka Jelínková who was interested in dance suites of the Little Queens. The first documented transformation of these rituals dates back to the period of official bans on skirmishes between Rides of Bachelors (during Pentecost) or carolling, the second one to the 1880s when the rituals began to be performed as part of the folklore movement. They are continuously revived as annual traditions (inspired by ethno-cultural customs). The present study deals with the disappearance and renewal and especially the transformation of boys’ ceremonial horseback processions and girls’ door-to-door processions in the historical territory of Moravia (and in one locality in Opava Silesia), based on participant observation, interviews with informants, and study of literature and sources.

The study deals with the transformation of traditional folk culture in the suburban zones and the participation of the municipality in the preservation of a living cultural heritage in its periphery. Settlements around Bratislava try to preserve their genius loci. They find inspiration in local traditional culture that is transformed into new forms and functions. The first part of the study explains the Bratislava Self-Governing Region’s support to the living cultural heritage. The second part focusses on periodic events in the public space, which have the character of festivals and in which the inspiration by the local traditional culture can be clearly identified. The conclusion of the study includes an analysis of these events in terms of cultural policy, participants, current functions and forms, commodification, and the degree to which the authenticity of the tradition is maintained.

Authors:   Etnografický ústav Moravského zemského muzea, Poláková Jana
Published: June 2024

The material report deals with a specific door-to-door procession, called a dudlačka, which takes place in the village of Lužná in the Vsetín area in the evening and night hours on Easter Sunday. It can be concluded from reports published in the professional litera- ture that the custom disappeared already in the 1940s. However, the field research con- ducted in 2018 and 2023 confirmed its continuity and high viability. The treatise presents a basic description of the custom in the past and present and its transformations, using various sources (archives, literature, field research).
The Lighthouse of EU Law Shines on the Polish Constitutional Tribunal
Authors: Spieker Luke Dimitrios
Published: June 2024

Last week, legal scholars from all over the world met in Freiburg at the ConTrans conference. On the one end of the spectrum, scholars like Woijcech Sadurski advocated for a revolutionary approach, simply dismantling the current Tribunal and re-building it from scratch. On the other end stands Adam Bodnar, who stressed the importance of legality in the transition process. In my view, EU law shines a possible way ahead – it can justify disregarding the Tribunal’s decisions and empower ordinary courts to assume the Tribunal’s jurisdiction. Eventually, this would lead to a decentralised constitutional review.

Quality Economic Growth: Is It Possible to Achieve by An Archipelago Area?
Authors: Telaumbanua Ya'aman
Published: June 2024

The purpose of this study, the researcher uses descriptive and verifiable analysis methods. Verifiable analysis through panel data regression analysis, by choosing the best approach from the Common Effect Model, Fixed Effect Model or Random Effect Model. The research variables consisted of natural resource factors (F_SDA) in the primary sector which were proxied from the contribution of the agriculture, forestry and fisheries sectors as well as the mining and quarrying sector to GDP, Foreign Investment (FDI), Government Expenditure (Blj_P), Average School Length (R_LS), Population Growth (Pert_Pduk) as free variables and Economic Growth (Pert_Ek) and Employment Opportunity Rate (TKK). Secondary data was obtained from BPS, the Ministry of Finance of the Republic of Indonesia, SatuData of the Ministry of Manpower. The type of data is panel data that was studied during the time period 2010 to 2019. The results of the study show that relatively high economic growth in areas with archipelagic characteristics does not have an impact on increasing employment opportunities. The F_SDA and FDI variables have no effect on economic growth in archipelagic areas, the Blj_P variables are influential and significant, while Pert_Pduk have an effect but not significantly on economic growth in archipelagic areas. The human resource factor variable that is proxied from the average of a long time (R_LS) has an effect but is negative and significant on economic growth in the archipelago. Overall, from this study, it was found that economic growth in the archipelago during the period from 2010 to 2019 was not of good quality.

The Emerging Issue of Using Rice Straw-Derived Carbon Material in Detecting Abused Weight Medication
Authors: Đỗ Mai Nguyễn
Published: June 2024

In this work, the experimental test is concentrated on developing a modified electrode – RTAC-modified GCE. RTAC or activated carbon extracted from rice straw would be applied to modify the bare GCE. This modified electrode would detect an abused pharmaceutical in feedstock - Terbutaline (TEB). The electrochemistry method employed in the test is a differential pulse anodic stripping voltammetry (DP-ASV). The DP-ASV analysis outcomes described that TEB would be determined with good selectivity and high sensitivity on RTAC/GCE, expressing a defined peak at 515 mV. The LOD – limit of detection and LOQ – limit of quantitation of TEB in this paper were calculated to be 0.237 µM and 0.782 µM, leading to the RTAC/GCE application in detecting TEB being ensured. It could be understood that the employed sensor is optimal to apply to find the analyte due to its fabulous selective and sensitive properties.
