Nonhuman Animal Agency: Human and Free-Roaming Cats’ Coexistence in Spinut Neighbourhood in Split, through an Interdisciplinary Artistic Practice

This artistic research was a one-year Master Performing Public Space program at Fontys School of Fine and Performing Arts in Tilburg, Netherlands. Based on concepts of coexistence between nonhumans and humans, it creates new narratives with the models of utopia, symbiocene, empathy. The author, while observing a community of free-roaming cats, co-created a series of interspecies communication and utopian experiments with humans and cats. The work is inspired by the author’s close intertwining with nonhumans and continues her artistic practice based in anthrozoology. It exemplifies artistic co-creation with nonhumans, more-than-human public space geography and the potential of artistic research as a scientific discipline

Preparation and evaluation of properties of cast metallic foams with regular inner structure

Lately we encounter still more new applications of metallic foams, as well as possible methods of their manufacture. These metallic materials have specific properties, such as large rigidity at low density, in some cases high thermal conductivity, capability to absorb energy, etc. The work is focused on the preparation of these materials using conventional casting technology, which ensures rapid and economically feasible method for production of shaped components. In the experimental part we studied conditions of casting of metallic foams with a regular structure made of ferrous and non-ferrous alloys. For thus obtained castings we evaluated the achieved microstructure and mechanical properties, which determine the possible use of these materials. The samples were subjected to compression tests, by which we investigated deformation behaviour of selected materials and determined the value of energy absorption.Web of Science6231646164

OSMIŠLJAVANJE I IZRADA KARTONSKE AMBALAŽE ZA BOBIČASTO VOĆE

The production of packaging products is experiencing annual growth. Packaging is made from a broad spectrum of materials with different properties. The European Union adopted Directive (EU) 2019/904 on reducing and preventing the environmental impact of certain plastic products. This directive aims to encourage a circular economy among consumers and producers by ensuring that single-use plastic products are not be placed on the market when suitable and affordable, more sustainable alternatives are available. Despite regulations, disposable plastic packaging for food products remains prevalent in the market. This research focused on disposable packaging for berries. A conceptual solution was devised from sustainable material suited for the food industry, alongside creating a product prototype. Additionally, a comparative visual study was conducted to evaluate the storage quality of berries in different packaging solutions. The study also included a of a survey, to assess participants\u27 awareness of the environmental impact of plastic packaging and to identify preferences for more sustainable alternatives. The presence of numerous packaging solutions can leave consumers uncertain about the most sustainable packaging.Proizvodnja ambalažnih proizvoda raste na godišnjoj razini.

Lažna farmakorezistencija - stvarni problem

Pharmacoresistant epilepsy poses a great burden to patients, their families, and the whole healthcare system, with numerous social, economic, physical, and psychical consequences. Hence, it is a diagnosis that has to be made only in cases of high certainty, after all potential causes of epilepsy have been evaluated. One of the important causes of pharmacoresistant epilepsy is false pharmacoresistance, an entity that implies a condition in which poor disease control is not a consequence of the biology of the disease itself, antiepileptic drug inefficacy, and/or patient specificity. It is a consequence of human error and strongly depends on the experience of the treating physician, as well as on the attitude of the patient. Despite its ‘falseness’, this entity is accompanied by real consequences for the patient and his family, and at the same time, it delays appropriate treatment of the actual disease from which the patient is suffering. In order to introduce appropriate treatment and avoid unnecessary and harmful diagnostic procedures, false pharmacoresistance is a condition that has to be ruled out in any patient with difficult-to-treat seizures.Farmakorezistentna epilepsija, dijagnoza koju prate brojne društvene, ekonomske, fizičke i psihičke posljedice, predstavlja veliko opterećenje za bolesnike, njihove obitelji, ali i cjelokupni zdravstveni sustav. Stoga je farmakorezistentnu epilepsiju opravdano dijagnosticirati samo u slučajevima u kojima je liječnik siguran u dijagnozu nakon što su procijenjeni svi mogući uzroci. Jedan od uzroka farmakorezistentne epilepsije je takozvana lažna farmakorezistencija, entitet koji podrazumijeva stanje u kojem loša kontrola bolesti nije posljedica biologije same bolesti, antiepileptičkih lijekova i karakteristika bolesnika. Ona je posljedica ljudske pogreške i izravno ovisi o iskustvu liječnika koji liječi, ali i o stavu bolesnika prema liječenju. Unatoč „lažnosti“ ovaj entitet prate stvarne posljedice za bolesnika i njegovu obitelj, a istodobno odgađa odgovarajuće liječenje stvarne bolesti od koje bolesnik boluje. Kako bi se osiguralo uspješno liječenje te izbjegli nepotrebni i štetni dijagnostički postupci, lažna farmakorezistencija je stanje koje se mora isključiti kod svakog bolesnika s epileptičkim napadajima koji se teško kontroliraju

Influencing of foundry bentonite mixtures by binder activation

Although new moulding processes for manufacture of high quality castings have been developed and introduced into foundry practice in recent years, the green-sand moulding in bentonite mixture still remains the most widely used technology. Higher utility properties of bentonite binders are achieved through their activation. This contribution is aimed at finding a suitable activating agent. A number of sodium salts and MgO based agents has been chosen. In the framework of the experiment the swelling volume of chosen agents was tested and technological parameters of a bentonite mixture with a binder activated with the studied agents were determined.Web of Science55110

Proposal of method of removal of mould material from the fine structure of metallic foams used as filters

Metallic foams are materials that are subject of an ongoing research with the broad applicability in many different areas (e.g. automotive industry, building industry, medicine, etc.). These metal materials contain in their structure artificially created pores. These pores give them specific properties, such as: large rigidity at low density, high thermal conductivity, capability to absorb energy, etc. Since the discovery of porous metallic materials numerous methods of production have been developed. The aim of the paper is to introduce effective casting methods of manufacturing of metallic foams, namely cast metal filters from the aluminum alloy. Research deals with investment casting with use of pattern made of polymeric foam, which is used for production of metallic foam with open pores. The main disadvantage of this procedure consists in removing the mould material without damaging the fine structure of the cast filter. Plaster is used as the mould material and the most important result of this paper is the presentation of the effective procedure of plaster removal from the porous structure of cast filters.Piany metalowe są przedmiotem wielu badań gdyż znajdują szerokie zastosowanie w wielu dziedzinach np. produkcji samochodów. budownictwie czy w medycynie. W swojej strukturze zawierają sztucznie wytworzone pory, zapewniające uzyskanie specyficznych właściwości jak duża wytrzymałość, niewielka gęstość, wysokie przewodnictwo cieplne zdolność do absorpcji energii itp. Od czasu wynalezienia porowatych materiałów metalowych opracowano wiele metod ich wytwarzania. Celem opracowania jest wprowadzenie efektywnych metod odlewniczych produkcji pian metalowych, szczególnie ze stopów glinu. Studium zajmuje się precyzyjną metodą odlewania przy zastosowaniu modelu wykonanego z piany polimerowej stosowanej w produkcji piany z otwartymi porami. Główna niedogodność metody polega na trudności usuwania materiału formierskiego, bez naruszenia delikatnej struktury odlewanego filtra. Jako materiał formierski stosuje się gips i najważniejszym wynikiem pracy jest przedstawienie efektywnej procedury usuwania gipsu z porowatej struktury odlanego filtra.Web of Science59273072

Production of microreactor systems by additive manufacturing technology

Microreactor systems are reactors with three-dimensional structures which are under a millimeter in size. They are commonly fabricated by wet and dry etching, precision machining, laser treatment, blasting and lithographic tech- niques. Additive manufacturing technologies have been overlooked in this area. This paper presents a part of research related to fabrication of microstructured reactors (microreactors and millireactors) by using two additive manufac- turing technologies (fused filament fabrication and stereolithography). One example of static mixer used in a milli- reactor and one reactor designed for uniform droplet production are also presented

Using Constraints in Freight Volume to Identify Regional Needs for Roadway Infrastructure

Policy decisions on the allocation of funds among sub-national regions for transportation infrastructure, specifically for motorways, face budgetary constraints and problems of geographical allocation. The purpose of this research is to assist the policymakers in efficiently allocating resources. The objective of this research is to test the ability of a limited model to identify regions whose freight transport capacity is constrained by lack of motorway infrastructure. This paper conducts an analysis of the relationship between freight transport volume, indicators of the demand for goods, indicators of congestion, and the availability of motorways and class one roadways across regions to determine if a model based on available data may inform the policymakers to effectively use limited funds and avoid unnecessary construction. The NUTS3 regions in the Czech Republic are used to estimate a preliminary model that may be generalized for the use across countries. The analysis finds sufficient variability across regions in the marginal effect of motorways on freight transport to assist the policymakers in determining which regions face the most economically severe constraints, and to separate the effects of population density from the lack of infrastructure. Although the Czech Republic is a developed country, there is significant emphasis, due to the increasing volumes of transportation flows, on the analysis of transportation in relation with the land use.</p
