Challenges in Engineering Education: Addressing Student Motivation
Full text linkLearning is a lifelong process. The saying 'You learn as long as you live' exists for a reason. Acquiring new
and unfamiliar knowledge, preparing for exams, completing assignments, and writing research papers can be
challenging and time-consuming. As educators, we always aim to give our best, simplifying complex concepts,
providing clear visual aids, and even offering simulations where possible. Our main goal is to engage students
effectively and maintain their attention throughout the learning journey. This is why the teaching materials provided by professors and the way they communicate to students are of great significance. In this paper, we will explore students' perspectives on teaching materials through a brief discussion, and we will draw conclusions to guide the future direction of the learning process
Современ пристап за одржливи практики во расителното производство
Full text linkДали има доволно храна во светот?
• Во 2020 година скоро 690 милиони луѓе или 8,9% од светската популација биле гладни.
• Зголемување на гладните за 10 милиони луѓе за една година и за речиси 60 милиони за пет години.
• Во 2019 година, близу 750 милионилуѓе - или скоро секој десетти човек во светот - биле изложени на сериозни нивоа на несигурност за достапност на храна.
• Околу 2 милијарди луѓе во светот немаа редовен пристап до безбедна, нутритивна и доволно хранаво 2019 година.
• Пандемијата COVID-19 може да додаде меѓу 83 и 132 милиони луѓе на вкупниот број на недоволно исхранети во светот во 2020 година во зависност од сценариото за економски раст.
• Нутритивниот статус на најранливите групи на население веројатно дополнително ќе се влоши поради здравствените и социо-економските влијанија на СОВИД-19.
• Светот не е на пат да постигне „нула гладни“ до 2030 година.

Sexual and domestic violence through the prism of adolescent literature
No full textThe subject of interest in the scientific article is the novel “Bela Sama” by the Macedonian writer Violeta Tancheva-Zlateva, published in 2023. The novel has a complex structural arrangement, because the narrative follows two generations within one family and all the joyful and beautiful events that occur, both in society and in the family. Hence, the author set herself the task of speaking out about some complex problems, which were otherwise shyly discussed in the past. Such is the problem of domestic and sexual violence. Tancheva-Zlateva speaks about this issue through the character of the girl Bela and her immediate family. The paper first examines domestic violence, patriarchal understandings related to the shame of speaking out publicly about violence, and then we also address sexual violence, which exists, most often hidden. Through a descriptive analysis of individual parts of the novel, the devastating impact of violent episodes within the family on a young person will be highlighted, and the need for open discussion about these bitter problems in society will be particularly emphasized
Distribution of Technology-Critical Elements in the Trepça Mine(Kosovo): Insights from Mineralogical, Geochemical and Microstructural Analyses
No full textThis study investigates the presence of Technology-Critical Elements in the Trepça mine (Stan Tërg, Mitrovicë), representing the first assessment of their distribution within this mining district. Samples were collected in all ore bodies (three samples per ore body) in horizons VIII-XI. Mineralogical, geochemical and microstructural haracterization was performed using X-ray diffraction (XRD), Inductively Coupled Plasma Mass-Spectrometry (ICP-MS), and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX). The analyses confirmed the presence of several Technology-Critical Elements,especially Bi, Co, Ge, W, Ga, In, Te and Sb, whose distribution, correlation with mineral phases and structure were also identified. XRD enabled the identification of mineral phases
while SEM-EDX provided structural and morphological characteristics of these mineral
phases. The ICP-MS results indicate significant variability in the distribution of these
elements. Bi reached extremely high concentrations (up to 2570.68 ppm in ore body 136),
well above the method detection limit (MDL = 0.01 ppm), whereas Co exhibited elevated
yet moderate concentrations that increased with depth, indicating a depth-dependent rise
in concentration. V, W, Sb and Sn also exhibited elevated concentrations. Peak enrichment levels were observed for Bi (up to 2750 ppm) in Horizon IX, Sb (up to 504 ppm) in Horizon XI, W (up to 308 ppm) in Horizon VIII, and In (up to 34,730 ppm) within selected ore bodies, indicating pronounced vertical geochemical zonation. The results demonstrate that selected ore bodies represent significant potential sources of Technology-Critical Elements,supporting future resources and strategic raw material assessment within the Trepça
mining district
Emphasis and Information Focus in English Cleft Constructions
No full textCleft constructions in English are syntactic structures in which a specific element of a sentence is extracted from its canonical position and placed within a separate clause in order to achieve greater emphasis. Commonly referred to as cleft sentences or cleft clauses, these constructions form complex sentences whose meanings could otherwise be conveyed by simpler structures. Their primary function is to bring a particular constituent into focus. In spoken discourse, this focusing effect is frequently reinforced by distinctive intonation patterns. Cleft sentences are widely used in English discourse to organize information by linking what is already known to the listener with newly introduced or highlighted content. Through the use of cleft constructions, speakers are able to direct attention to the most communicatively significant part of the message

Predictive analytical workflow for rapid structure elucidation and in silico toxicological qualification of an unidentified impurity in cefixime granules for oral suspension
Full text linkDuring in-use stability testing of cefixime granules for oral suspension, an impurity with a relative retention time of 0.19 was consistently detected and increased during storage. To ensure regulatory
compliance and patient safety, the impurity was structurally identified and toxicologically qualified. A laboratory-scale formulation
and commercial products were studied under refrigerated and
ambient conditions. The impurity was isolated by automated fraction collection and characterised by liquid chromatography-mass
spectrometry and tandem mass spectrometry. Kinetic evaluation
showed pseudo-first-order formation, with faster accumulation at
ambient temperature. The impurity was identified as a g-lactone
degradation product of cefixime, present as multiple stereoisomers
stabilised under acidic conditions. In silico toxicological assessment
using complementary platforms indicated no additional structural
alerts, no mutagenic potential, and negligible acute toxicity. The
impurity forms only after prolonged storage of reconstituted suspensions and is classified as an ICH M7 Class 5 impurity, requiring
no further genotoxicity testing. The applied analytical-computational workflow provides an efficient approach for impurity qualification in b-lactam antibiotics
