Národní úpravy směrnice č. 96/71/ES ve vybraných členských státech EU
Authors: Martin Štefko , Joklová Kateřina , Kotrčová Šárka
Published: January 2025

This paper analyses the Posted Workers Directive 96/17EC (hereinafter “the Posted Workers Directive”) as it was implemented in Belgium, France, Italy and the United Kingdom. The Posted Workers Directive itself is not a subject of this paper. However, the author focuses on said national law systems and studies different states’ approaches how the said directive was introduced in legal practice. The Posted Workers Directive is a compromise enacted in order to settle a conflict between two important interests. On one hand, there are companies established in an EU Member State that are awarded contracts in other EU Member States. These companies enjoy the freedom to provide services. Therefore, they have right to relocate their employees to the host EU Member State to fulfil the contract. On the other hand, the host state’s trade unions (and other subjects) claim that service providers take advantage of cheaper labour standards in their own states to win a contract in the host state, to the detriment of employment in the host state. Hence, there is a clash of the freedom to provide services and the host state’s social policy.
How can be seen on French Implementation of the Posted Workers Directive Jed (potential) problems connected with foreign service providers on French territory to highly protective national regulations. On the contrary, the United Kingdom has shown to be reluctant in introduction of any new statute which would set forth rules for employees relocated in accordance with the Posted Workers Directive. The financial crises may change the opinion of the United Kingdom Government but so far the United Kingdom’s labour market has no problems with activity of foreign employees relocated by foreign service providers. In fact, the United Kingdom approach is not a liberal approach to foreign service providers and their employees relocated to the United Kingdom’s territory. Using the concept of public law, the government insists on application of a large part of national employment law. The example of two other EU Member States, Belgium and Italy, demonstrates that every EU Member state implemented the Posted Workers Directive in its own way. However, there is one feature common to all surveyed states. Every EU Member State used the Posted Workers Directive to protect their local interests and differences. Nevertheless, the Posted Workers Directive is one of several secondary acts that harmonise national choice of law rules of EU Member states. The unification of national law of conflict is a step to the harmonisation of the whole employment law.

„Iliada” Homera widziana oczyma ilustratorów – Johna Flaxmana i Stanisława Wyspiańskiego
Authors: Kossak-Nowocień Hanna
Published: January 2025

This paper is a contribution to studies into the reception of ancient literary works, focusing on the reception of one of the greatest masterpieces of antique literature, The Iliad. Homer’s epic has repeatedly inspired both other ancient authors and artists of later periods. This was also the case with two exceedingly versatile artists, John Flaxman and Stanisław Wyspiański. Rather than go into analytical comparisons of the scenes they recreated, this study attempts to highlight the professional approach of both artists to their commissions, outline their respective techniques and the manner in which they envisioned the stories they would subsequently depict.

Authors: Wang Guanglian , Zhu Zhenxin , Sun Zhengang , Yang Zhiqi
Published: January 2025

This study was to analyze the effect of triptolide (TPL) on proliferation, apoptosis, and the relationship between TPL and the Janus kinase/signal transducer and activator of transcription signaling pathway in hepatoma cells. HepG2 cell line was selected as the experimental object and divided into control, low-dose TPL, medium-dose TPL, and high-dose TPL group. The control group did not receive any drug treatment, while the low, medium, and high-dose groups were treated with TPL at concentrations of 0.02, 0.05, and 0.10 μM, respectively. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide, flow cytometry, and western blot were used to detach the TPL effect and mechanism. The cell proliferation inhibition rate in each dose group of TPL was lower than that in the control group, and the inhibition rate of cell proliferation increased with the increase of TPL dose (P < 0.05). The apoptosis rate of TPL in each dose group was higher than that in the control group, and the apoptosis rate increased with the increase of TPL dose (P < 0.05). The expression of phosphorylated Janus kinase 1 (p-JAK1) and phosphorylated signal transducer and activator of transcription 3 (p-STAT3) protein in cells of each dose group of TPL was lower than that in the control group, and the expression of p-JAK1 and p-STAT3 protein decreased with the increase of TPL dose (P < 0.05). The apoptosis rate of 10 ng/mL transforming growth factor-beta + high-dose group was reduced than that in the high-dose group, and the expression of p-JAK1 and p-STAT3 protein was higher than that in the high-dose group (P < 0.05). The activity of B-cell lymphoma/leukemia-2-associated X protein (Bax) protein and cysteine aspartic acid protease (Caspase)-3/9 in TPL cells at each dose was raised than that in the control group, and the expression of B-cell lymphoma/leukemia-2 (Bcl-2) protein was decreased than that in the control group. With the increase of TPL dose, the activity of Bax protein and Caspase-3/9 increased, and the Bcl-2 protein decreased (P < 0.05). As an anti-liver cancer agent, TPL inhibits the proliferation of hepatocellular carcinoma cells and promotes apoptosis. The mechanism may involve inhibiting Janus kinase 1/signal transducer and activator of transcription 3 pathway and activation of apoptosis-related pathways.

Authors: Beumer Prieto Blanca , Moreno-Parro Isabel , Sufrate-Vergara Berta , Fabre-Estremera Blanca , Buño Soto Antonio , Fernández-Calle Pilar , Díaz-Garzón Marco Jorge
Published: January 2025

Objectives

Cardiac biomarkers are useful for the diagnostic and prognostic assessment of myocardial injury (MI) and heart failure. By measuring specific proteins released into the bloodstream during heart stress or damage, these biomarkers help clinicians detect the presence and extent of heart injury and tailor appropriate treatment plans. This study aims to provide robust biological variation (BV) data for cardiac biomarkers in athletes, specifically focusing on those applied to detect or exclude MI, such as myoglobin, creatine kinase-myocardial band (CK-MB) and cardiac troponins (cTn), and those related to heart failure and cardiac dysfunction, brain natriuretic peptide (BNP) and N-terminal brain natriuretic pro-peptide (NT-proBNP).

Methods

Thirty athletes participated, providing monthly fasting blood samples over 11 months. Samples were analyzed using chemiluminescent immunoassays and statistical analyses were conducted using the classical ANOVA method, a linear mixed model and a Bayesian approach.

Results

The study observed significant gender differences in biomarker concentrations, with higher BNP and NT-proBNP in females and higher myoglobin and CK-MB in males. Physical activity within 24 h before sampling notably affected CK-MB, myoglobin, and hs-cTnI variability. The BV estimates demonstrated high individuality for most biomarkers, suggesting their potential for personalized monitoring. The study also revealed substantial heterogeneity for NT-proBNP and BNP within the population.

Conclusions

These findings underscore the importance of considering gender-specific reference intervals and the impact of recent physical activity when interpreting cardiac biomarkers in athletes. The study delivers new BV estimates for CK-MB and myoglobin while emphasizing the need for tailored clinical assessments in athlete populations.

Published: January 2025

This paper presents a comparative study on the calibration of magnetometer sensors, focusing on three methods: the least square method, the ellipsoid fitting method, and a proposed sequential method. The effectiveness of the first two methods is investigated, and their results are compared with the outcomes achieved through the application of the sequential method. Practical data is utilized to demonstrate the advantages of the proposed method. Through this research, insights are provided into the performance and limitations of the least square and ellipsoid fitting methods, while highlighting the superior capabilities of the sequential method. The results show that the sequential method inherits the capabilities of both method and leads to a more reliable calibration.
Optical branched flow in nonlocal nonlinear medium
Authors: Zhao Tongxun , Wang Yudian , Peng Ruihan , Wang Peng , Ye Fangwei
Published: January 2025

When light propagates through a randomly correlated, slowly varying medium, it generates optical branched flow. Previous studies have demonstrated that the self-focusing effect in optical media can accelerate the appearance of the first branching points and sharpen the filaments of branched flow. In this study, we investigate the influence of the nonlocality of the nonlinear response on branched flow. We find that, due to its averaging effect, as the range of nonlocality increases, the first branching point shifts to a greater distance, and the flow structures broaden, thus nonlocality ultimately restores the branched flow to its linear condition. We have developed a semi-analytical formula and confirmed the screening of the self-focusing effect on branching flow by nonlocality.

Published: January 2025

Objectives

β-thalassemias, caused by mutations in HBB, are hereditary blood disorders that impose a significant global health burden. Detecting these mutations through accurate genetic analysis is essential. This study aimed to create a panel of cell type reference materials for β-thalassemia genetic testing using prime editing (PE), a flexible and precise genomic editing method.

Methods

PE3 systems were designed to target specific HBB mutations, including single nucleotide variants (SNVs) (−32 (C>A), CD 17 (A>T)), insertions (CD 14/15 (+G), CD 71–72 (+A)), and deletions (CD 31 (−C), CD 41/42 (−TTCT)). HEK293T cells were edited to carry these mutations. Sanger sequencing was performed to confirm the accurate introduction of homozygous and heterozygous mutations. The cell lines were further verified using commercial reverse dot-blot hybridization and melting curve assays.

Results

We successfully constructed 12 stable HEK293T cell lines carrying the intended homozygous or heterozygous HBB mutations using PE3 systems. No off-target mutations in the HBB were detected by Sanger sequencing in these stable cell lines, even after more than 10 weeks of culturing. Additionally, all target mutations were accurately and consistently detected using two reverse dot-blot hybridization kits and one melting curve assay kit.

Conclusions

The 12 stable cell lines exhibited accurate and stable HBB mutations, making them valuable reference materials for β-thalassemia genetic testing. PE3 systems show potential for generating a comprehensive panel of HBB mutations, particularly those that are clinically rare.

THE EFFECT OF GARMENT CUTTING ON FIBER LENGTH RETENTION IN WOOL-BLEND OFFCUTS WITH RESPECT TO THEIR FUTURE USE IN RECYCLED YARN PRODUCTION
Authors: Basho Megi , Chavoshi Ava , Cebulla Holger
Published: January 2025

The growing demand for sustainable textile production highlights the importance for effective recycling of pre-consumer textile waste, particularly wool and wool blends. Production highlights the importance of recycling pre-consumer textile waste to minimize the environmental impact. While many studies focus on fiber recycling, few investigate the root cause of the fiber shortening during the cutting and shredding process. This study investigates how cutting fabric impacts fiber retention in recycled yarn production, focusing on three common knit patterns—Rib 1x1, Double Jersey, and Interlock. Using a 70% wool and 30% silk blend, the study identifies optimal cutting dimensions to minimize fiber loss during recycling. Experimental analyses of fabric samples (1–10 cm lengths) revealed that cuts of approximately 7 cm effectively preserved fiber lengths across all patterns, with confidence intervals demonstrating consistent retention. Image processing techniques further categorized leftover materials, enabling their allocation to specific spinning processes (short-staple, medium-staple, and long-staple). The findings contribute to optimizing recycling processes, improving fiber retention, advancing circular economy practices in textile production, and hold potential for practical implementation in automated recycling systems and enhanced yarn production workflows.

Authors: Gani Abdul Rasyid Fakhrun , Hastuti Utami Sri , Sulisetijono Sulisetijono , Setiowati Frida Kunti
Published: January 2025

This research trains the students’ ethnomedicine literacy by using project-based learning and augmented reality assistance and evaluating the learning effectiveness. The research method used was a non-randomized control group pretest-posttest design, and a problem-based learning model was used as a control class. This research evaluates students' ethnomedicine literacy using descriptive statistical data analysis, n-gain scores, and ANCOVA tests. The research results showed differences in ethnomedicine literacy with an ANCOVA significance value of 0.08 between the experimental and control classes. Both classes showed increased ethnomedicine literacy, but the n-gain score for the experimental class was greater than that of the control class. Students' ethnomedicine literacy is higher in the experimental class because there are learning activities that empower ethnomedicine literacy, such as students are trained to be broad-minded, have positive attitudes and behavior related to ethnomedicine studies, working on simple manufacturing projects based on student research to get closer to the environment and society, and using AR as a simulation for testing the antibacterial power of medicinal plants. This research concludes that AR-assisted project-based ethnobotany learning is proven to be able to increase students' ethnomedicine literacy. This research can be helpful as a learning design reference to empower ethnomedicine or other literacy in biology.

Published: January 2025

The case method and team-based projects in the mechanics course are designed to help science teacher candidates master the principles of mechanics. This study aims to analyze the readiness and constraints of technological integration in implementing the case method and team-based projects in the mechanics course of the natural science education program. The study was conducted using a survey method with respondents or samples consisting of two lecturers teaching the mechanics course, 64 pre-service science teachers, and an analysis of the mechanics course documents in the Science Education Study Program at a state university in Central Java, Indonesia. Data collection techniques for this study were carried out using a blended approach (online and face-to-face), a Google Forms questionnaire, online interviews (zoom meeting), and document review. Data analysis was carried out using the triangulation method, which combines various predetermined data and sources, including data from the mechanics course lecturers and students and the lecture tool documents. The results indicate that the readiness for implementing the case method and team-based project in the mechanics course is supported by a good understanding from lecturers and students and adequate resources. The student’s understanding of the approaches used by the lecturer obtained concept approach (71.40%), direct instruction model (85.70%), and discussion method (78.60%). In its implementation, the case method follows the theory and expectations in the mechanics lectures in the curriculum documents. Meanwhile, team-based projects still need improvement and development in their application to the mechanics course. The skills trained in the mechanics course are still limited to critical thinking skills, communication, and collaboration. Generic science skills have been trained but have not been specifically labeled, and creative thinking skills have not been technically facilitated to be trained. The carrying capacity of the learning environment is quite good based on ICT. However, it is still dominated by PowerPoint presentations and virtual lab applications, while coding blocks and AR-VR have not yet been developed. The conclusion indicates that while there is strong readiness and adequate resources for implementing the case method and team-based projects in the mechanics course, significant constraints exist in developing creative thinking skills, generic science skills, and consistency in applying learning models. Specific improvements are needed in the practical application of team-based projects and the integration of ICT that can assist mechanics lectures, such as coding blocks and AR-VR technology. It is recommended to enhance comprehension of the case method and team-based projects among lecturers and students and to advance technological integration, especially focusing on AR-VR and coding blocks.

Published: January 2025

Differences in students’ cognitive style aspects allow for differences in students’ conceptions of their understanding of Newton’s laws. This study aims to determine the profile of students’ conceptions in-depth based on their cognitive styles. This research used a qualitative method with a descriptive phenomenological design involving cognitive style tests with GEFT (Group Embedded Figured Test) on 30 students to be categorized based on their cognitive styles. From the 30 participants, three strongly field-dependent and three strongly field-independent students were selected. Six selected students were diagnosed using a four-tier diagnostic instrument for their understanding and conceptions. Semi-structured interviews were also conducted to investigate the students’ conceptions in depth. This study concludes that field-independent (FI) students frequently display an inclination toward analytical thinking by self-exploring. However, they frequently experience difficulties in analyzing concepts without a solid foundation in physics, which can result in certain theoretical misconceptions. Conversely, field-dependent (FD) students can receive a broader range of information but demonstrate difficulties in analytical tasks, such as interpreting graphs and establishing causal relationships between physical quantities, which can result in correlational misconceptions. To rectify this misconception, it is imperative to implement a bespoke pedagogical strategy that integrates efficacious elucidations, tangible exemplifications, structured scaffolding, inquiry, and methodical practical exercises.

The aim of this study was to determine the effect of authentic inquiry project practicum on Nyale in improving critical and creative thinking skills of prospective science teacher students. The method used was experimental research method with one group pretest postest. The research subjects involved science education students of one of the universities in Sumba in the 2023/2024 academic year who contracted animal anatomy and physiology courses. The instrument used in this research was a critical and creative thinking skills test. The results of the Wilcoxon test showed that in experimental classes 1 and 2 there was an effect of practicum on the critical and creative thinking skills of prospective science teacher students as evidenced by the Asymp. Sig. (2-tailed) 0.000 < than 0.05. In addition, the N-gain test results showed an increase in critical thinking skills before and after practicum in experimental classes 1 and 2 with moderate categories. While the N-gain test of creative thinking skills showed an increase in the creative thinking skills of prospective science teachers in the moderate category for experimental class 1 and in the low category for experimental class 2. From the results obtained, it can be concluded that the authentic inquiry project practicum on Nyale is effective in improving the critical and creative thinking skills of prospective science teachers.

Wnt7a-Cre is a commonly used driver for generating uterine epithelial conditional knockout mice, such as epiERα
−/− (Esr1

f/−

Cre/+
) and epiPR
−/− (Pgr

f/−

Wnt7a

Cre/+
). We noticed that epiERα
−/− females, but not epiPR
−/− females, have prolonged plugging latency, which is the duration between continuous cohabitation and detection of the first vaginal plug (a sign of mating). Mating occurs in proestrus and/or estrus stages of the estrous cycle. Vaginal cytology detected estrous cyclicity in all mice examined, although epiERα
−/− mice had leukocyte-dominant vaginal cytology throughout the estrous cycle and their estrous cyclicity appeared less regular. Estrous cyclicity and mating activity are regulated by the hypothalamic–pituitary–ovarian axis, in which kisspeptin plays essential roles. ERα and PR are expressed in the rostral periventricular area of the ventricle (RP3V) and arcuate nucleus (ARC) kisspeptin neurons in the hypothalamus. It has been reported that Esr1

Kiss1-Cre mice lack estrous cyclicity, while Pgr

Kiss1-Cre mice have normal estrous cyclicity at two months old, and Wnt7a is highly expressed in ARC. The prolonged plugging latency in epiERα
−/− mice could be contributed by the deletion of ERα in Wnt7a-positive cells in ARC. Wnt7a-Cre was also used to generate uterine epithelial RhoA-deficient mice, epiRhoA

Комплексы сетчатокрылых изучались в 2022-2023 гг. с помощью приманочных ловушек на местах пожаров 2021 г., через 12-13 лет после пожара 2010 г. и на не подвергавшихся пожарам участках в Мордовском заповеднике. Оказалось, что сильные пожары, при которых уничтожается вся или почти вся растительность, по-разному влияют на разные экологические группы сетчатокрылых. Они благоприятны для хортобионтых златоглазок (например, Chrysopa abbreviata, Ch. walkeri, Ch. commata) и опушечных видов (например, Apertochrysa prasisaи A. ventralis), в результате чего их численность возрастает. Но такие пожары очень неблагоприятны для дендробионтов, особенно таких видов, как Nineta alpicola, N. vittata и Chrysotropia ciliata, которые могут исчезать в местах пожаров или очень долго не могут восстановить свою численность.

We examined neuropteran assemblages of the Mordovia Nature Reserve collected in 2022 and 2023 using bait traps at the site of 2021 and 2010 fires and in areas not exposed to these fires. We found that the fires, in which almost all vegetation was destroyed, had different effects on different ecological groups of Neuroptera. Fires were favorable for chortobiont (herb-dwelling) species (e. g., Chrysopa abbreviata, Ch. walkeri, Ch. commata) and species preferring forest edges (e. g., Apertochrysa prasisa and A. ventralis) which increased their numbers. Such fires were, however, very unfavorable for dendrobiont (tree-dwelling) species, especially e. g., Nineta alpicola, N. vittata and Chrysotropia ciliata, which disappeared from burned areas or were unable to restore their numbers in this time.
ИЗУЧЕНИЕ ЛЕСОВОССТАНОВИТЕЛЬНЫХ СУКЦЕССИЙ НА РАЗНЫХ СТРУКТУРНЫХ УРОВНЯХ (НА ПРИМЕРЕ ПОСЛЕПОЖАРНЫХ СУКЦЕССИЙ В ЛЕСАХ СИХОТЭ-АЛИНЯ)

На основе известных положений системного подхода рассматриваются некоторые узловые вопросы сукцессионных преобразований на биогеоценотическом (экосистемном), фитоценотическом, микроценотическом и популяционном структурных уровнях на примере послепожарных сукцессий в широколиственно-кедровых и темнохвойно-кедровых лесах Сихотэ-Алиня. В исследованиях на биогеоценотическом уровне использованы индикационные методы, основанные на анализе градиентов ведущих факторов среды по блокам индикаторных видов и региональным экологическим шкалам. Основное внимание на фитоценотическом уровне изучения сукцессий уделено вопросам видового и ценотипического состава сообществ. На микроценотическом уровне рассматривали вопросы преобразования основных элементов мозаики фитоценозов (синузий и микроценозов) и их эквивалента в биогеоценозах (парцелл). На популяционном уровне устанавливали онтогенетические состояния растений разных видов и возрастную структуру ценопопуляций, рассмотрена динамика всхожих семян, находящихся в латентном онтогенетическом состоянии в подстилке и почве.

Based on the well-known provisions of the general theory of systems, some key issues of successional transformations at the biogeocenotic (ecosystem), phytocenotic, microcenotic and population structural levels are considered on the example of post-fire successions in broad-leaved Korean Pine and dark coniferous Korean Pine forests of Sikhote-Alin. In research at the biogeocenotic level, long-term regime observations of individual environmental factors were used, as well as indicative methods based on the analysis of gradients of leading environmental factors by groups of indicator species, blocks of diagnostic species according to the Brown-Blanke ecological and floristic approach and regional ecological scales. The main attention at the phytocenotic level of the study of successions was paid to the issues of spatial structure, species and cenotypic composition of communities, dynamics of the number and productivity of communities. At the microcenotic level, the issues of transformation of the main elements of the mosaic of phytocenoses (synusions and microcenoses) and their equivalents in biogeocenoses (parcels) are considered. Ontogenetic states and the age structure of cenopopulations were established at the population level.
