1. Review of magnetic nanomaterials for the electrochemical sensing of antibioticsJosip Radić, Lidija Fras Zemljič, Sara Perša, Olivija Plohl, 2025, pregledni znanstveni članek Opis: Antimicrobial resistance (AMR) is increasing worldwide. This is due to the widespread and often uncontrolled release of antibiotics into surface water, drinking water, and the food chain. The traces of antibiotics (ng/L to μg/L) bioaccumulate, disrupt ecosystems, and accelerate AMR, yet regulatory monitoring remains inadequate. Sensitive analytical methods for the detection and quantification of antibiotics at trace levels in complex matrices are therefore essential. Conventional techniques, i.e., liquid or gas chromatography, mass spectrometry, and capillary electrophoresis, offer high accuracy but are associated with costly instrumentation, lengthy workflows, and extensive sample preparation. Electrochemical sensors based on advanced nanomaterials, particularly magnetic nanoparticles (MNPs), have attracted considerable interest due to their advantages in sensitivity and selectivity, wide linear dynamic ranges, extremely low limits of detection (LOD) and quantification (LOQ), low instrument cost, and rapid response. This review provides a critical overview of recent advances in MNP-based electrochemical platforms for antibiotic detection. The focus is on wet-chemical synthesis routes, modification approaches, and strategies for integrating magnetic nanocomposites into electrodes. Synergistic improvements through hybrid architectures are emphasized, combining MNPs with carbon nanomaterials, biopolymers, metal–organic frameworks, and molecularly imprinted polymers. Trends over the last five years have shown that applications in environmental monitoring, food safety, and drinking water are increasing. We summarize the key performance metrics, outline the current technical bottlenecks, such as long-term stability and large-scale manufacturing, and provide an outlook for the future. Taken together, these developments position MNP-based electrochemical sensors as versatile, highly effective tools for curbing antibiotic pollution and slowing the advancement of AMR.

2. Supply chain integrity : addressing ethical concerns in agricultural supply chainsPaul Mukucha, Thulani Dube, Divaries Cosmas Jaravaza, 2025, izvirni znanstveni članek Opis: Ethics has become a trending phenomenon in most disciplines as a result of the sustainability wave enshrined in the United Nations Sustainability Goals (SDGs). In business circles procurement ethics have become topical as a result of the rising malpractices whose ripple effects have far reaching economic, social and environmental consequences. In the agricultural supply chains procurement ethics have been called to question due to outcries from the tobacco contract farmers whose livelihoods are affected by supplier development washing in the form of exorbitantly priced contract farming inputs. The unethical practice of supplier development washing in the form of exorbitantly priced tobacco contract farming inputs has some ripple effects which this study sought to determine. Twenty-five contracted tobacco farmers were interviewed and the results indicated that farmers subjected to tobacco merchants’ unethical conduct tend to practice contractor switching, side marketing, become insolvent, and indulge in unorthodox cost cutting measures. The study recommended that the regulatory authorities should intervene to bring sanity to the tobacco supply chains through enforcing contract farming mechanisms that reflect genuine supplier development.

3. Vpliv varjenja na mehanske lastnosti jekla SA 500 : magistrsko deloRene Peklar, 2025, magistrsko delo Opis: Magistrsko delo obravnava vpliv varjenja na mehanske lastnosti jekla SA 500 z dodajnim materialom EZ - MIG 307 Si. Uporabljen osnovni material spada med protibalistična jekla, ki imajo dobre mehanske lastnosti, zlasti trdnost in trdoto. Ker varjenje degradira osnovni material, bomo analizirali njegov vpliv na mehanske lastnosti. Izvedli smo natezni preskus, instrumentiran Charpyjev preskus in merjenje trdote po Vickersu. Z omenjenimi mehanskimi preskusi smo potrdili, da ima osnovni material visoko trdnost in trdoto, vendar je dokaj krhek. Z vnosom toplote (varjenjem) se ta krhkost odpravi in material postane bolj žilav, vendar se mu drastično zmanjšata trdnost in trdota.
Ključne besede: Protibalistično jeklo, avstenitni nerjavni dodajni material, varjenje, mehanski preskusi zvarnih spojev.

5. The loss of a close person – intersections between law and psychology : case of Polish lawMarlena Drapalska-Grochowicz, 2023, izvirni znanstveni članek Opis: The Polish legislator allows for compensation for the harm suffered due to the death of close person resulting from a tort (for example, a car accident). The basis for such claims is Article 446 § 4 of the Polish Civil Code, which contains a vague expression “the closest family member.” Courts must therefore determine whether and how someone was close to someone. The language of the judicial justifications indicates that the courts do not determine proximity solely based on legal criteria. In this publication, I will analyze court decisions in which the scope of the vague expression “the closest family member” has been adjudicated. The analysis aims to establish the legal understanding of closeness in the indicated case and to determine whether and how references to psychology support it.
Ključne besede: close person, legal closeness, grief, law and psychology, material closeness

7. Izdelava lutk v vrtcu iz odpadnega materiala : diplomsko deloSabina Kos, 2025, diplomsko delo Opis: Diplomsko delo z naslovom Izdelava lutk v vrtcu iz odpadnega materiala je sestavljeno iz teoretičnega in praktičnega dela.
V teoretičnem delu smo na podlagi strokovne literature predstavili teoretična izhodišča, ki zajemajo emocionalni in socialni razvoj od tretjega do četrtega leta, vlogo lutk v tem obdobju, vrste lutk in načine ustvarjanja in uporabe lutk v vrtcu. Predstavili smo okoljsko vzgojo v vrtcu Lenart ter uporabo odpadnega materiala v vrtcu.
V praktičnem delu smo s pomočjo štirih priprav, ki so vključevale štiri etape, in sicer pobudo, načrtovanje, izvedbo, sklepno fazo, načrtovali projektno delo v vrtcu Lenart s končnim ciljem izdelave lutk iz odpadnega materiala. Otroci so bili vključeni v vse etape. V sklepni etapi smo na pobudo in predlog otrok izdelane lutke animirali skozi dialoge, ki so potekali med simbolno igro. Otrokom smo želeli predstaviti uporabnost odpadnega materiala in jim predstaviti možnosti za izdelavo lutke iz odpadnega materiala. Zastavljeni cilji projektnega dela v diplomski so bili doseženi. Otroci so izdelali lutko iz odpadnega materiala, pri tem so bili ustvarjalni in motivirani. V zadnji sklepni etapi so se preizkusili v animaciji izdelanih lutk in s tem ustvarjali svoje zgodbe.

8. Reading adapted texts of young adult fiction and reading motivation of pupils with speech and language disordersNika Vizjak Puškar, Tina Vršnik Perše, Dragica Haramija, 2025, samostojni znanstveni sestavek ali poglavje v monografski publikaciji Opis: The research studied how reading of adapted young adult fiction effects reading motivation of Slovene elementary school pupils with speech and language disorders. The research involved 50 pupils from the last three years of elementary school. Typically, pupils with these disorders do not enjoy reading during adolescence, as texts that would be suitable to their age and interests in terms of content are most often incomprehensible or linguistically too demanding for them. For the purpose of the research, we adapted two complete works of Slovene literature into an easy-to-read form (passages version in easy language). Pupils intensively read the adapted texts and also looked at the originals. This had positive effects both on their comprehension of the literary texts as well as their reading motivation. The results of the research demonstrated that adapted texts positively influence the reading motivation of pupils and their perception of literature.

9. Razvoj novih 2D avksetičnih struktur z uporabo genetskega algoritma : magistrsko deloJernej Kojzek, 2025, magistrsko delo Opis: V magistrski nalogi so predstavljeni razvoj in rezultati optimizacije novih 2D avksetičnih struktur z uporabo genetskega algoritma in metode končnih elementov. Razvita je optimizacijska zanka, s katero se strukture generirajo, simulirajo in ocenijo. Osnovna celica se v strukturo zloži po vnaprej določenem vzorcu. Mehanski odziv struktur je določen z linearno elastičnimi simulacijami, pri čemer se kot obremenitev uporabi pomik. Ker vse generirane strukture ne izkazujejo avksetičnega obnašanja, se za ločevanje dobrih in slabih uporabi matematična ocena.
Ključne besede: avksetični material, genetski algoritem, metoda končnih elementov, topološka optimizacija

10. In-plane deformation behavior and the open area of rotating squares in an auxetic compound fabricPolona Dobnik-Dubrovski, Nejc Novak, Matej Borovinšek, Matej Vesenjak, Zoran Ren, 2022, izvirni znanstveni članek Opis: A conventional compound fabric was used to develop a modern, multifunctional material
with an auxetic behaviour and a tailored open area for particle filtration. Such material was produced
using traditional textile technology and laser cutting, to induce a rotating squares unit geometry. The
behaviour was investigated of three different rotating unit cell sizes. The laser slit thickness and the
length of the hinges were equal for all three-unit cells. The tensile properties, Poisson’s ratio and
auxetic behaviour of the tested samples were investigated, especially the influence of longitudinal
displacement on the fabric’s open area and the filtered particle sizes (average and maximum). Results
show that the developed compound fabric possesses an average negative Poisson’s ratio of up to
−1, depending on the applied auxetic geometry. The larger rotating cell size samples offer a higher
average negative Poisson’s ratio and a higher breaking strength due to the induced slits. The findings
highlight the usefulness of patterned cuts in conventional textile materials to develop advanced
auxetic textile materials with tailored geometrical and mechanical properties.
