A reflection on women’s strength in Perempuan Luka Kalis Kecewa
No full textMadihah, who was the top SPM student in 2008, reached a remarkable milestone earlier this year with the publication of two of her latest books. As a young and promising author in Malaysia, her first work was a co-authored book with Ummu Hani Abu Hassan, titled Catatan Hati Nik Nur Madihah – Kesusahan Bukan Penghalang Kejayaan, published in 2009. Her second book, Noktah Terjahit, was released in 2017, followed by her third book, Denai Cinta, in 2023.
In 2025, Madihah achieved double success when her books Perempuan Luka Kalis Kecewa and Kemelut: Konflik Perasaan Sering Dilalui Pelajar hit the bookstores in April and May, respectively. To maintain a clear focus, this article serves only as a review and reflection on Perempuan Luka Kalis Kecewa. Insha Allah, once this task is completed, I will address the issues explored in Kemelut in a separate article
Techno-economic analysis of a geothermal district heating system
No full textGeotermalna energija je idealna tehnologija za povećanje udjela obnovljivih izvora u proizvodnji električne i toplinske energije. Povijesno je bila ograničena na geološki aktivnija područja, ali se napretkom prvenstveno ORC tehnologije ostvaruje mogućnost primjene na izvorima s relativno niskom temperaturom termalne vode. Korištenje geotermalne energije u svrhu grijanja sve više postaje mogućnost čak i kod izvora s niskim temperaturama. Nove energetski visokoučinkovite zgrade ne zahtijevaju visoke temperature u sustavu grijanja pa se toplinske potrebe mogu zadovoljiti i iz niskotemperaturnih izvora. Ukoliko zgrade nisu niskoenergetske ili je kombinacija zgrada raznih energetskih karakteristika što je i najčešći slučaj, postoji mogućnost korištenja geotermalnih dizalica topline samostalno ili u kombinaciji s nekom drugom tehnologijom. U sklopu ovog rada su razmatrana moguća tehnička rješenja primjene geotermalne energije u svrhu proizvodnje električne i toplinske energije. Razmatrane su dvije lokacije (Rečica i Lanište) i za svaku je izrađeno nekoliko tehničkih rješenja. Prikazuje se proračun CTS-a i njegovih komponenata te geotermalnog binarnog ORC-a. Određivanje toplinskog opterećenja je provedeno stupanj – sat metodom, a radna karakteristika svake komponente sustava je modelirana pripadajućom funkcijom. Kako bi se odredila najbolja kombinacija instaliranih snaga pojedinih komponenata, provedena je tehno – ekonomska analiza. Za slučaj lokacije „Rečica“ su napravljene 4 varijante korištenja izvora: izgradnja binarnog ORC postrojenja i CTS-a u obližnjim naseljima, izgradnja binarnog ORC postrojenja i spoja na CTS grada Karlovca, samo opskrba CTS-a u Karlovcu te izgradnja samo ORC postrojenja. Na lokaciji „Lanište“ je napravljeno također 4 varijanta: izgradnja novog CTS-a i opskrba putem geotermalne dizalice topline, kombinacija geotermalne dizalice topline i kotla s električnim grijačem, kombinacija geotermalne dizalice topline i kotla na prirodni plin, kombinacija geotermalne dizalice topline i kotla na biomasu. Na lokaciji „Rečica“ su svi scenariji s izuzetkom scenarija izgradnje ORC-a i novog CTS-a u naseljima Rečica i Luka Pokupska profitabilni s unutarnjim stopama povrata iznad 20 %. Najprofitabilniji je scenarij izgradnje geotermalnog ORC postrojenja. Scenariji razmatrani na lokaciji Lanište nisu isplativi unutar 15 godina te je potrebno uložiti nepovratna sredstva ili povećati cijenu toplinske energije. Najbolji od projekata na toj lokaciji je kombinacija geotermalne dizalice topline koja radi u baznom opterećenju te kotla na prirodni plin koji pokriva vršna opterećenja.Geothermal energy is reliable renewable energy source. It has historically been limited to usage only on geologically active locations, but with the advancements in ORC technology, it has become viable to use relatively low temperature heat sources. New highly energy efficient buildings do not require high water temperature in their heating systems. Therefore, it is possible to use lower temperature heat sources. The most common case when designing district heating network is combination of buildings with differing thermal properties. In that case, additional heat source may be required to provide desired temperature of heating water. This can be geothermal heat pump standalone or in combination with electric heater, natural gas boiler or biomass boiler. In this thesis, two possible locations (Rečica and Lanište) were analyzed for usage of geothermal energy in electricity and heat generation. Few technical solutions were made for each of them. This thesis describes the procedure of designing DH network with all of its components and geothermal binary ORC. Yearly heat load distributions were made by using the degree – hour method. Each component of the facility is described with mathematical function. For each scenario techno – economic analysis has been made. It shows which scenario is better and worth investing and also enables comparison between various scenarios. At the site “Rečica”, four scenarios were made: use of geothermal energy solely for electricity generation with ORC, combination of ORC and new district heating system in nearby towns Rečica and Luka Pokupska, combination of electricity generation in ORC and supply of existing district heating system in Karlovac City and only supply of DH in Karlovac. Four scenarios were also made for the second location, “Lanište”: New district heating system based on geothermal heat pump, on combination of geothermal heat pump and electric heater, combination with the natural gas boiler and combination with biomass boiler. All of the scenarios at the site “Rečica” with exception of new ORC and DH in Rečica and Luka Pokupska are profitable with internal return rate above 20 %. The most profitable scenario is the one which includes electricity generation in geothermal ORC facility. At the site “Lanište”, none of the scenarios are profitable within 15 years. However, they can be made profitable with the application for EU funding or by increasing heat prices. The best scenario at this site is combination of geothermal heat pump for covering the base load with natural gas boiler for peak demand
Modern and Site Specific. The Architecture of Gino Valle 1946-2003
No full textThis edition makes available for the first time in English the only critical
monograph dedicated to the work of Gino Valle, realized with Luka Skansi with an enormous support of Piera Valle and Pietro Valle. Since his
early buildings in the 1950s at Udine in Friuli, northeast Italy, Gino
Valle has been recognized by
international critics as Joseph Rykwert (author of a Foreword to the
book) and Reyner Banham as one of the most original and creative
European architects of the post-war period. His artistic talent,
associated with a great intellectual curiosity and a genuine passion for
new construction systems, led Valle to develop an architectural work
that was resolutely open and multiform. His buildings make valuable
contributions to debates about the relationship between new architecture
and historic surroundings, between industrial and open landscape, urban design and architectural intervention
Tehno-ekonomska analiza centraliziranog toplinskog sustava baziranog na geotermalnoj energiji

Totalitarianism on Screen in the Light of H. Arendt's Political Thought
No full textU ovom radu autor nastoji dokazati komplementarnost političke teorije i filma odnosno pokazati kako se zajedničkim promatranjem spomenutih medija stvara kompleksnija slika razmatranog fenomena. Kako bi dokazao tezu, on analizom filmova Šoa, Šaulov sin i Raj utvrđuje njihove filozofsko-teorijske potencijale te na njihovom primjeru istražuje međudjelovanje političke teorije i filma. Budući da je u analizi filmova fokus na prikazu totalne dominacije na filmu, autor, prije same interpretacije, sažeto prikazuje političku teoriju Hanne Arendt koja identificira upravo totalnu dominaciju kao vrhunac totalitarne vladavine. Ipak, totalnu dominaciju nije moguće razumjeti per se. Stoga, rad prezentira instrumente i preduvjete koji su omogućili nastanak i održanje totalitarizma, a samim time i totalne dominacije. Prema Arendt, totalna dominacija je projekt koji pomoću ideologije i terora uništava čovjeka kao biće slobode. Autor na samom početku rada postavlja širi okvir koji omogućuje bolje shvaćanje moći, djelovanja, slobode i politike. Točnije, svih onih karakteristika koje krase čovjeka kao biće slobode, a koje totalna dominacija nastoji uništiti. Autor dokazuje kako navedeni filmovi posjeduju filozofsko-teorijski potencijal te da arendtijanska interpretacija stvara nova filmska značenja i dimenzije. Također, rad pokazuje kako filmovi ilustracijama transformiraju kompleksne teorijske koncepte u jednostavnije i razumljvije oblike. Autor zaključuje kako su politička teorija i film uistinu komplementarni te ističe važnost ovakvog pristupa i potiče daljnja istraživanja u ovom području.In this paper, the author tries to prove the complementarity of political theory and film. In other words, he tries to show how the joint observation of the mentioned media creates a more complex picture of the considered phenomenon. To prove the thesis, the author analyzes films Shoah, Saul's Son and Paradise, brings to light their philosophical-theoretical potential and explores the interaction between political theory and film. Because film interpretation is based on the depiction of the total domination in film, the author, before analyzing, summarizes Hannah Arendt's political theory, which identifies total domination as the zenith of totalitarian rule. Total domination cannot be understood per se, therefore, the paper presents the instruments and preconditions that enabled the emergence and maintenance of totalitarianism and thus total domination. According to Arendt, total domination is a project that uses ideology and terror to destroy man as a being of freedom. At the very beginning of the paper, the author sets a broader framework that enables a better understanding of power, action, freedom and politics. All those traits characterize man as a being of freedom and total domination seeks to destroy them. The author shows that these films have philosophical-theoretical potential and that the Arendtian interpretation creates new cinematic meanings and dimensions. Also, the paper shows how films use illustrations to transform complex theoretical concepts into simpler and more understandable forms. The author concludes that political theory and film are complementary, emphasizes the importance of this approach and encourages further research in this area

Comparison of different configurations of the energy system of the Republic of Croatia in energy transition
No full textRepublika Hrvatska, kao članica Europske Unije i potpisnica Pariškog Klimatskog Sporazuma ima obvezu pridonijeti svjetskom naporu ograničavanja porasta prosječne globalne srednje temperature za 2 °C, a poželjno i unutar 1,5 °C. Konkretan cilj ovih ograničenja je postupno smanjivanje emisija stakleničkih plinova te dostizanje klimatski neutralnog energetskog sustava do 2050., što se u slučaju Hrvatske planira postupnim smanjenjem korištenja fosilnih goriva uz povećanje proizvodnje iz varijabilnih obnovljivih izvora energije (VOIE).
Uz povećanje korištenja OIE, potrebno je provoditi mjere povećanja energetske učinkovitosti, naročito u stambenom sektoru, te uvođenje međusobne povezanosti između sektora potrošnje koji se počinju oslanjati na isti energetski vektor. Hrvatska u ovom smislu ima i prednost nepovoljne demografske situacije čime se olakšavaju napori prema tranziciji energetskog sustava te se osim uz primjenu mjera energetske učinkovitosti i uz negativan prirodni prirast, smanjuje potrošnja energije.
Također, dodatan cilj koji se ostvaruje u ovom radu je dostizanje energetske nezavisnosti Republike Hrvatske što kao rezultat ima povoljne učinke na stabilnost i pouzdanost energetskog sustava, a i eliminira negativnu tržišnu bilancu sa zemljama izvoznicama fosilnih goriva.
U ovom radu se razmatra izgradnja proizvodnih kapaciteta iz VOIE uz istovremeno smanjivanje kapaciteta termoenergetskih postrojenja te implementacije mjera fleksibilnosti i pohrane energije. Primjenom navedenih promjena u energetskom sustavu, dolazi se do samoodrživog sustava s visokim udjelom obnovljivih izvora energije. Također, postižu se ukupni godišnji troškovi nižeg iznosa u usporedbi s baznom godinom kako u ukupnom iznosu, tako i po stanovniku, uz gotovo nultu emisiju stakleničkih plinova i tek neznatno višom potrošnjom biomase.
Sve u ovom radu korištene tehnologije već su danas prepoznate kao izrazito obećavajuće i moguće za skoru primjenu. Razmatrajući brzinu napretka i poboljšanja određenih tehnologija, uvode se pretpostavke smanjenja troškova. Ipak, na primjeru tehnologija poput električnih baterija je vidljiva određena mjera odstupanja brzine poboljšanja tehnologije, tj. projicirana poboljšanja su često podcjenjivala stvarna poboljšanja, što dodatno pridonosi smanjenju godišnjih troškova, a time i isplativosti sustava.The Republic of Croatia is a member of the European Union and a signatory state to the Paris Climate accords. With signing of Paris Climate accords, it has taken over an obligation to take part in the global effort with the goal of limiting the increase of average global mean temperature by 2 °C, and preferably within 1,5 C. The means of reaching this goal are presented in gradual decrease of greenhouse gas emissions with the goal of reaching net zero emissions energy system by the year 2050. Republic of Croatia plans to achieve this goal with the gradual decrease of fossil fuel use while at the same time increasing generation from renewable energy sources.
In addition to increasing the use of renewables, there is also a necessity to implement energy efficiency measures, especially in the housing sector, and to introduce cross-sector linkages between consumption sectors that are beginning to rely on the same energy vector. In a sense, Croatia has somewhat of the advantage due to unfavorable demographic situation, which facilitates efforts towards the transition of the energy system and, in addition to the application of energy efficiency measures, also acts to reduce energy consumption.
Additional goal achieved in this paper is the achievement of Croatia’s energy independence which reflects favorably on the stability and reliability of the energy system and eliminates the negative trade balance with fossil fuel exporting countries as well.
This thesis discusses the construction of variable renewable energy generation capacities, while reducing the capacity of thermal power plants. At the same time, flexibility options and energy storage technologies are being implemented. The self-sufficient energy system with high share of renewable energy sources is achieved with the application of said technologies. Results show that total annual costs are lower compared to the base year, both in total and per capita, with almost zero greenhouse gas emissions and only slightly higher biomass consumption.
All the technologies considered in this thesis are already recognized as highly promising and applicable in a near future. Considering the rate of improvement, the assumptions of cost reduction of considered technologies are introduced. However, technologies such as electric batteries show a certain measure of deviation in the rate of technology improvement. For example, projected improvements often underestimated the actual improvements, which further contributes to reducing total annual costs and thus the cost-effectiveness of the system
La linea analitica: Dardi, lʼarte e lʼesposizione
No full textBased on archival research conducted at the Archivio Progetti at IUAV in Venice, the essay (and the exhibition “La linea analitica: I musei e gli allestimenti di Costantino Dardi”, Archivio Progetti, Iuav, 12.11. > 13.12.2013) is the first historical and scientific survey on the exhibition designs by Costantino Dardi, the renowned Italian architect of the 1970s and 1980s, author of the scenography for Peter Greenaway’s “The Belly of an Architect”.
Across the various exhibition contexts in which he operated, Dardi nurtured a strongly critical approach to the relationship with space: he did not limit himself to merely an expressive or representative level, but rather assumed an analytical attitude. This attitude produced new and always original operations: as results of a critical and creative analysis of space, his projects often became spatial installations in themselves. Dardi’s work found its optimal expression in the relationship between the exhibition display and its context, whether the latter was a museum, an archaeological site, an urban space or a landscape. This particular sensitivity derives from his wide and updated knowledge of visual culture, which in the context of contemporary Italian architectural milieu was quite original. Although perfectly positioned within the Italian architectural culture of the ‘60s and ‘70s, Dardi nevertheless emerges as an anomalous exponent, primarily for his in-depth and articulated knowledge of the Italian and international art scenes. It was precisely contemporary art research (Flavin, Burden, Judd) that strongly influenced his analytical sensitivity as well as design
