Characteristic cutting tool wear mechanisms analysis
No full textTema ovog rada su tvrdi metali uključivo njihov kemijski sastav, mikrostuktura, svojstva, mehanizmi trošenja i područje primjene. Najzahtjevnija primjena tvrdih metala je za alate koji se koriste za obradu odvajanjem čestica. Ovisno o materijalu, uvjetima rada i načinu rada na reznoj oštrici javljaju se određeni oblici trošenja. Matematičkim putem trošenje je gotovo nemoguće detektirati i kvantificirati. Stoga se danas velika pažnja posvećuje eksploatacijskim ispitivanjima te je u eksperimentalnom dijelu rada provedeno ispitivanje trošenja jednoreznim alatom u približno realnim radnim uvjetima kako bi se razmotrilo koji se oblici trošenja najčešće javljaju kod reznih alata. Radi se obradi tokarenjem pri čemu je rezna pločica od tvrdog metala, a kao obradak koristi se trupac od sivog lijeva. Nakon obrade, kamerom se snimaju određene površine rezne oštrice te se pomoću odgovarajućeg računalnog programa mjere oštećenja na prednjoj i stražnjoj površini reznog alata. Razmatranjem rezultata mjerenja dolazi se do zaključka koji su mehanizmi trošenja dominantni na tvrdo-metalnoj reznoj pločici.The topic of this paper are hard metals including their chemical composition, microstructure, properties, wear mechanisms and application area. The most demanding application of hard metals is for tools used for particle separation processing. Depending on the material, operating conditions and operation of the cutting blade there are certain forms of wear. Mathematical wear is almost impossible to detect and quantify. Therefore, great attention is paid today to the exploitation tests and in the experimental part of the work, a one-tool wear test was carried out in roughly realistic working conditions to consider which forms of wear most often occur in cutting tools. It is machined by turning, whereby the cutable is made of hard metal, and as a grain is used a gray cast iron. After processing, the camera captures certain areas of the cutting blade and uses the appropriate computer program to measure the damage to the front and back surface of the cutting tool. Considering the measurement results, it comes to the conclusion that the wear mechanisms are dominant on the hard-metal cutting plate

The sociocultural construction of urban wasteland: Mapping of the Antwerp Southside
No full textAny process of growth, decline and transformation can be understood from a spatial reading, unraveling the traces left on the ground and observing elements temporarily unable to adapt to the flow of time: wasteland. The concept of wasteland is an artificial ‘construction’ usually linked to the idea of (un)productivity. As society changes, the productive use of land changes through time. This chapter aims to reveal the cumulative alternation of western perception in land use value. The means to read this shift is the historical cartographic analysis on the Southside of Antwerp (Belgium). As constructions of reality, maps are loaded with intentions and interpretations of the culture in which they are produced. In particular, the historical mapping of wastelands generated by industrial and agricultural production focuses on understanding the evolution in interpreting fundamental issues such as time, processes and changes related to land ownership.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care.

Before the very elaboration of the collection "What All", the paper explains the time and the area in which the collection belongs, its origin and division. In addition, poetry is elaborated, highlighting the latest division of poetry and poetry for children, poetry in general, its emergence and the emergence of children's poetry, in which the Collection of Songs belongs as well. In addition to poetry, the paper deals with dialect and slang, specifically about colloquialism, based on language, style and dialect in which the Collection is written. Furthermore, the paper turns to the understanding of reading itself and the source of children's and adults' motivation to read literature works (e. g. the Collection of Songs) and also, the importance of reading to children. After that, the work proceeds to the elaboration of the Collection of Songs, first based on the life and work of the author of the Collection - Nikolina Manojlović Vračar, and then on the concept of the Collection, the division, its main theme, i. e. the verbs that pervade the whole Collection, experience the Collection and its purpose to children. The text of the Collection is elaborated according to the rhyme, the verse, and the strings, and their rules, and, in this way, gives a comparable number of examples. In addition, poetic images and stylistic figures are also elaborated with numerous examples and quotes. At the very end of the paper, the illustrations of the Collection, which were designed by the author herself, are enclosed with a few examples illustrating the illustrations, where they can be found, and how they fit into the story of the Collection itself
A LABYRINTH OF LITERARY FICTION AND LIFE REALITY
No full textThe subject of this short review is the literary-theoretical and literary-critical analysis and interpretation of “Always with Me” by the literary debutant Nikolina Kostovska. It is a contemporary Macedonian novel published this year (2021) and within its structure the author leads us through a labyrinth of three interconnected stories that are presented in three narrative units of the novel: “Prologue”, “First Part” and “Second part”. This narrative labyrinth in the novel is realized with a postmodernist game in which the boundaries between fiction and faction are relativized through three narrative units in its content: fiction in fiction, fiction as literary reality and fiction as life reality. In this review, the stated specifics of the novel will be analyzed in details, which will show that “Always with Me” by Kostovska is a successful and significant novelistic achievement in Macedonian contemporary literature.
Keywords: novel, Nikolina Kostovska, fiction in fiction, post-modernistic prose, Macedonian contemporary literature
Comparison of women characters in the oral and author fairy tales of Ivana Brlić-Mažuranić and Vladimir Nazor
No full textU završnom radu opisuje se lik žene u hrvatskim usmenim i autorskim bajkama Ivane Brlić-Mažuranić i Vladimira Nazora. U usmenim bajkama ističu se rodne uloge, posebice patrijarhalni odgoj i način života žene. Žene su vrlo često bile prikazivane i kao glavni krivci za nesreću koja se dogodila, smatralo se kako su upravo one glavni uzrok svakom zlu pa ih se zbog toga često kažnjavalo batinama. Takve primjere pronalazimo u knjizi Hrvatske bajke koju je priredio Jozo Vrkić (1997). Nekoliko bajki iz knjige interpretirano je s detaljnijim osvrtom na ženske likove. Ponešto drugačiju situaciju zatičemo u autorskim bajkama s početka 20. stoljeća kada se hrvatska bajka najljepše ostvarila u djelima Vladimira Nazora, Ivane Brlić Mažuranić, Jagode Truhelke i Josipa Cvrtile (Pintarić 2008: 15). Likovi Ivane Brlić Mažuranić ponekad pogriješe, ali je njihova ljepota upravo u tome da iz te spoznaje izrastaju obraćeni i ponovo rođeni. Ženki likovi detaljno su opisani u njenim najpoznatijim bajkama. Istaknut je snažan utjecaj majčinstva, roditeljstva, ženske ustrajnosti, ljubavi i hrabrosti koje su odlika njenih žena. To je posebice istaknuto u bajkama „Ribar Palunko i njegova žena“ u kojoj pratimo aktivnu borbu ženskog lika u želji ponovnog okupljanja vlastite obitelji te „Šumi Striborovoj“ u kojoj čarolija i raskoš šume nestaju pred snagom i ustrajnošću ženskog (majčinskog) identiteta. S druge strane u Nazorovim bajkama nema klasičnog sukoba između dobra i zla te zaslužene nagrade i kazne. Opisani su njegovi ženski likovi koji su ustrajni u borbi za dobrobit svih. Likovi su usko povezani s prirodom, posebice životinjama. Njegova gušćarica Anka, Halugica i Koraljica najsvijetliji su primjer tome.The following graduate thesis is describing the character of women in the oral and author fairy tales of Ivana Brlić- Mažuranić and Vladimir Nazor. In oral fairy tales, gender roles, especially patriarchal education and upbringing and the way of life of women, are emphasized. Women are commonly represented as the main culprits for the misfortune that happened, and it is believed that they are the main cause of every evil. That is why they were often beaten. Such examples are found in the book Hrvatske bajke by Jozo Vrkić (1997). Several fairy tales from the book were interpreted with a more detailed look at female characters. Something different situation is found in author fairy tales from the beginning of the 20th century when croatian fairy tales were best performed in the works of Vladimir Nazor, Ivana Brlić Mažuranić, Jagoda Truhelka and Josip Cvrtila (Pintarić 2008: 15). The characters from authoress Ivana Brlić Mažuranić fairy tales sometimes make mistakes, but that is why at the end they become wiser and born again. The female characters in her most famous fairy tales are explained in details. The main highlight is on the strong influence of motherhood, parenthood, female perseverance, love and courage that are the characteristics of her women characters. This is especially noted in the fairy tale Palunko i njegova žena where we follow the brave struggle of a woman's character to reunite her own family and the Striborova Šuma where the magic and the beauty of the forest disappear with the strength and perseverance of the female mother's identity. On the other hand, in Nazar's fairy tales, there is no classic conflict between good and evil and deserved reward and punishment. His female characters are fighting for the wellbeing of everyone. The characters are closely related to nature, especially to animals. His Anka, Halugica and Koraljica are the best examples
Analiza imidža Zorana Milanovića u hrvatskoj javnosti
No full textKroz ulogu predsjednika stranke, premijera pa u konačnici i predsjednika Zoran Milanović postao je dio hrvatske svakodnevice. Autorica istražuje imidž Zorana Milanovića jer je on postao znatno prepoznatljiva ličnost zbog svojih navedenih uloga. Često je u fokusu medija, što znači da su njegov imidž i način kroz koji se percipira u javnosti postali važno pitanje. Autorica želi dublje razumjeti kako javnost vidi Zorana Milanovića, kako se on sam predstavlja na društvenim platformama i medijima te kako se njegov imidž oblikuje u hrvatskoj javnosti. Cilj ovog rada je odgovoriti na pitanje percepcije Zorana Milanovića u hrvatskoj javnosti, kao i utvrditi ključne čimbenike njegova imidža. Provedenim istraživanjem utvrđeno je da je imidž Zorana Milanovića zasnovan na njegovoj retorici u kojoj se ne libi prekršiti norme uobičajenog političkog govora. Rad donosi pregled dostupne stručne literature na temu političkog komuniciranja i imidža.Through the role of party president, prime minister, and ultimately head of state, Zoran Milanović became an integral part of Croatian everyday life. The author investigates the image of Zoran Milanović because he has become a significantly recognizable personality due to his aforementioned roles. He is often discussed and written about in the media, which means that his public image and the way he is perceived by the public have become an important issue. The author wants to understand more deeply how the public sees Zoran Milanović, how he presents himself on social platforms and the media, and how his image is shaped in the Croatian public. The aim of this paper is to answer the question of the perception of Zoran Milanović in the Croatian public, as well as to determine the key factors of his image. The conducted research showed that the image of Zoran Milanović is based on his rhetoric, in which he does not hesitate to violate the norms of ordinary political speech. The paper provides an overview of the available professional literature on the topic of political comedy and image
