ANALYZING STUDENTS' ABILITIES AS PROSPECTIVE TEACHERS OF MATHEMATICS IN CONSTRUCTING PROOFS: A STUDY OF GEOMETRY AND ALGEBRA
Authors: Widadah Soffil , Juniati Dwi 
Published: January 2024

Mathematical proof demands accuracy and precision in formulating correct and logical arguments. Students need to develop their ability to produce accurate and precise proofs. This study aims to analyze the ability of prospective mathematics teachers in constructing geometry and algebraic proofs. The research subjects were 8 prospective mathematics teacher students, four male and four female. This descriptive qualitative research begins with giving tests to research subjects, then we conduct interviews. The results showed that male students were better at compiling geometry proofs than compiling algebraic proofs. While female students are better at compiling algebraic proofs than geometry. This is due to the spatial ability of men better than women. When compiling geometry proofs apply procedural proofs, syntactic proofs, and semantic proofs. When compiling algebraic proofs only apply procedural proofs. Female students when compiling geometry proofs only apply procedural proofs. When compiling algebraic proofs, they apply procedural proofs and syntactic proofs.
Legacies of Leadership
Authors: Lemke Christiane 
Published: January 2024

Abstract
Leaving office after 16 years as German chancellor, Angela Merkel has multifold and complex legacies. While Merkel's leadership style has frequently been described as cautious in domestic politics, her role in international relations is often characterized as that of an active defender of liberal international norms and values. Yet she was also responsible for some of the most controversial decisions regarding Europe, often raising questions about Germany's commitments and goals. This article explores her foreign policy and her role in the European Union through a gender-sensitive lens. It examines the scope and significance of her leadership based on three case studies to allow for a differentiated analysis: the Eurozone crisis, the migrant crisis, and the COVID-19 crisis.
Pandemic Politics in the Federal Republic
Authors: Patton David F. 
Published: January 2024

Abstract
This article assesses the distinctiveness of the COVID-19 pandemic's impact on German party politics. To do so, it compares and contrasts the politics of the pandemic with those of four other historic crises—the catastrophic flooding of August 2002; the 2008–2009 global financial crisis; the European Union's sovereign debt crisis; and the refugee influx of 2015–2016. It examines the extent of a “rally-round-the flag” effect; how political parties framed the crisis in terms of solidarity; and the impact of retrospective assessment and voting on crisis management. The article finds that the political consequences of the coronavirus pandemic on the whole resembled past patterns, notwithstanding the unprecedent nature of the 2020–2021 crisis.
Dealing with Radical Right Parties in Distinct Arenas
Authors: Heinze Anna-Sophie , Lewandowsky Marcel 
Published: January 2024

Abstract
In this article, we develop and apply a typology of formal and substantive party responses to the radical right in three arenas: parliament, party competition, and the media. We argue that these provide distinct environments for parties’ scope of action, which is why responses must always be understood in the light of their respective context. Empirically, we focus on the case of the Federal Republic of Germany and illustrate the usefulness of our model by analyzing the responses of the largest conservative and social democratic mainstream parties in the Bundestag (CDU/CSU and SPD) to the Alternative for Germany (AfD) between 2017 and 2022. Although both coalition partners have primarily excluded the AfD at the formal and substantive level, we find crucial differences in their response patterns between the arenas and highlight future research perspectives.

Objectives. To investigate the swelling of the main types of rubbers used in the rubber industry in carbon dioxide in a supercritical state (SC-CO2), in order to assess the possibility of obtaining elastomeric materials with porous structures using fluid technology, based on them.Methods. The process of swelling of rubbers in SC-CO2 and subsequent foaming was carried out according to a specially developed technique using the original installation. This is a high-pressure apparatus with transparent windows, allowing for the use of an optical technique to directly measure the geometric dimensions of samples during swelling and foaming using a digital video camera. The study of the porous structure of foamed rubbers was carried out using scanning electron microscopy.Results. The study established experimental curves of the swelling kinetics in SC-CO2 of isoprene, butadiene, styrene butadiene, ethylene propylene, chloroprene, ethylene acrylate, siloxane, and organofluorine rubbers. The influence of temperature and pressure on the rate and equilibrium degree of swelling was studied. The diffusion coefficients of SC-CO2 in rubbers of various chemical natures were also determined.Conclusions. It was shown that the equilibrium swelling degree of rubbers in SC-CO2 depends on the chemical nature of rubbers. It does not correlate with the value of their solubility parameters, changes directly proportional to the diffusion coefficient and increases with increasing temperature and pressure. It was found that irrespective of the degree of swelling in SC-CO2, all the rubbers studied are intensively foamed at a sharp pressure drop. The size of the pores formed is tens of microns: significantly smaller than the size of pores formed when chemical pore formers are used.

Authors: Dyachenko A. N. 
Published: January 2024

Objectives. To study the technological features of a new fluoride technology for the production of titanium dioxide by the decomposition of titanomagnetite concentrate with ammonium fluorides.Methods. The chemical species of the titanium and iron components in the fluorination of titanomagnetite concentrate and sublimation separation of components were determined by means of X-ray powder diffraction analysis and inductively coupled plasma mass spectrometry. The kinetics of sublimation of the titanium component by the thermal decomposition of ammonium hexafluorotitanate was experimentally studied.Results. The products of the fluorination of titanomagnetite concentrate with ammonium bifluoride are compounds (NH4)2TiF6 and (NH4)3FeF6, as proven by chemical analysis and X-ray powder diffraction analysis. The subsequent sublimation separation of the titanium component produced the target product: a mixture of ammonium fluorotitanates. The desublimation of the titanium-containing fraction gave an NH4TiF5–(NH4)2TiF6–(NH4)3TiF7 mixture, the titanium content of which is 30.6% and the content of impurities (Fe, V, Si) is a minimum (0.45%). The activation energy of the heterogeneous reaction and the rate-limiting step of the process were also determined.Conclusions. A high-purity titanium product (a mixture of ammonium fluorotitanates) is obtained. This is a valuable commercial product for the industrial production of titanium dioxide pigment from titanomagnetite concentrate and ilmenite.

Peer assessment is a fundamental activity aiming to involve students to participate actively in their own learning processes. In the context of EFL online learning, the peer assessment was conducted in the online mode as well. This study aimed to: 1) compare studentsâ€™ attitudes in doing an online peer assessment in two different conditions of anonymity, 2) explore studentsâ€™ perceptions of the anonymous and identifiable online peer assessment. Â Seventy students of the English language education department in a private university participated in this study. Assigned to two different conditions, i.e anonymous and identifiable online peer assessment, the students were engaged in a Workshop activity, which was an asynchronous Moodle-based online peer assessment. Each student assessed three peersâ€™ works as well as provide feedback comments. A questionnaire with close-ended and open-ended questions was used to investigate the studentsâ€™ attitudes as well as perceptions of the different peer assessment formats. An independent samples t-test was performed to compare the attitude scores of both groups. The result indicated that students in the anonymous group showed a slightly better attitude compared to those in the identifiable group, yet the difference was not significant (t = 1.164, p > .05). From the questionnaire result, it was also found that the students in the anonymous group had more positive perceptions towards online peer assessment activity. These findings imply that while the anonymous online peer assessment is more favoured by learners, it might not be able to guarantee positive development in studentsâ€™ overall aspects of attitudes.

Introduction. Despite modern advances in research into the risk of development, immunological control and treatment options for lung cancer (LC), it is the leading cause of death from cancer. Tobacco smoking remains the predominant risk factor for the development of lung cancer, especially one of its aggressive subtypes, squamous cell lung cancer (SCLC). Benzo[a]pyrene, a component of cigarette smoke, promotes the activation of the aryl-hydrocarbon receptor (AhR). AhR regulates the expression of many oncogenes, including PD-L1, the positive status of which is an indication for immunotherapy, one of the main treatment strategies for SCLC. However, to improve the effectiveness of treatment of SCLC, further search for new diagnostic, prognostic and therapeutic markers is necessary. MicroRNAs (miRs), which are highly stable and present in biological fluids, can act as such markers.Objective. Search for microRNAs that could potentially serve as diagnostic markers or therapeutic targets for SCLC. For this purpose, microRNAs were selected whose promoter regions contain AhR binding sites or whose target is PD-L1.Materials and methods. A biocollection of tumor and conditionally normal lung tissue samples (n = 40) was collected at the thoracic department of the Novosibirsk Clinical Oncology Dispensary. The relative levels of selected miRNAs were examined using real-time reverse transcription-PCR (RT-PCR) technique.Results. The levels of miR-342 and miR-181a in SCLC tissues were reduced by 3 times relative to conditionally normal tissue. The expression of miR-181a and miR-155 is associated with tumor size (lower levels in tumors larger than 3 cm) and the presence of metastases in the lymph nodes (3- and 2-fold lower levels in cases with metastases). The level of miR-146a decreased by 3 times in patients with metastatic lesions of lymph nodes. A significant relationship between the levels of miR-93, miR-181a and miR-155 and the expression status of PD-L1 was also found.Conclusions. The expression profile of miR-146a, miR-93, miR-181a and miR-155 differs in SCLC patients depending on PD-L1 status and the presence or absence of lymph node metastases.
