Savremeni detalj u zoom-in-zoom-out tehnici - Bog i razmera

Considering both the visual and narrative character of architectural discourse it is possible to examine the capacity of a drawing as an autonomous form, but also as one assigned to it throughout the course of creation of new architecture. This paper's intent is to examine the place and the role of the architectural drawing of the detail within design research. Thematically different, the narratives are instruments used for creating a relationship between the project as a whole and its parts, while the detail defines the path from an idea to the realization of architecture, that is, from abstraction to concretization within the above-mentioned process. The notion of scalar imagination has been introduced in order to indicate the relationship between the traditional modernist understanding of the roles of detail and scale have, while the question of the real size of designed architecture has been moved aside. The scalar imagination reveals the relationships between the elements of architecture, while its visibility reveals the architect's ability to build the necessary information network while moving throughout the diverse levels of those relationships. The goal is to avoid vagueness of architecture represented by the drawing and favor the polyvalence of its meaning by presenting concrete information. In that sense, for the benefit of achieving clarity within the methodological approach, we researched the conditions of visibility within the relationship between the drawing and its meaning. Therefore, this paper focuses on the scale as a direct connection between the drawing of the detail and the continuity of the idea of architecture.Imajući u vidu i vizuelni i narativni karakter arhitektonskog diskursa moguće je ispitivati kapacitet koji crtež ima kao autonomna forma, ali i onaj koji mu se pretpostavlja tokom postupka stvaranja nove arhitekture. Namera je da se ovim radom ispita mesto i uloga crteža arhitektonskog detalja u istraživačkom projektovanju. Tematski odvojeno, narativi su instrumentalizovani kao konstruisanje odnosa između celine i delova projekta, dok se detaljem definiše put od ideje do realizacije arhitekture, odnosno od apstrakcije do konkretizacije unutar pomenutog postupka. Skalarna imaginacija pojmovno je uvedena kao veza između tradicionlno modernistički shvaćenih uloga detalja i razmere, dok je pitanje realne veličine projektovane arhitekture pomereno u stranu. Skalarana imaginacija je uzeta za manifestaciju odnosa između elemenata arhitekture, a njena vidljivost za sposobnost arhitekte da, krećući se kroz različite nivoe tih odnosa, gradi neophodnu mrežu informacija. Cilj je da se konkretnošću informacija izbegne zamagljenost crtežom predstavljene arhitekture u korist polivalentnosti njenih značenja. U tom smislu, zarad jasnoće metodološkog postupka, istraženi su uslovi vidljivosti veze između nacrtanog i označenog, a ovaj rad u fokus stavlja razmeravanje kao direktnu konekciju između nacrtanog detalja i kontinuiteta ideje o jednoj arhitekturi

U tezi, nakon kratkog pregleda dobro poznatih rezultata, posebna pažnja je posvećena savremenim doprinosima, gde je dat i pregled već objavljenih autorovih rezultata, kao i detaljan tretman novih dobijenih rezultata. Posebno je razvijena teorija lokalizacije Geršgorinovog tipa generalizovanih karakterističnih korena i pokazana je primena rezultata u problemima optimizacije bežičnih senzor mreža

Causes and effects of financial crises in global economy

The scientific and professional public today often wonders why the Great depression (Krugman) from 1929 is relevant to all the crises which later occured, thus relevant to the financial crisis of 2008. Certainly there are reasons why the Great depression (breakdown) from 1929 isalso relevant tothe major crisis from 2008. In both cases the government knew what should be done. In both occasions it refused to do so. In the spring of 1929 several strict words from a high position, higher discount rates and determined investigation of pyramid schemes of the time could lead to the fall of house of cards on the Wall Streetbefore its fall destroyed the entire economy.

Originally, the current crisis is related to living space, where the problem was not the lack of it, but rather its abundance. Financial crises that took place during the 20th century, and especially during 1970s (official beginning of the globalization of the world economy) were consequences of the implosion of property prices or large depreciations of national currencies on the foreign exchange market. In some cases foreign exchange crises led to bank crises in other cases it was vice versa. Huge amounts of fictive capital that circle around the planet create a possibility to flood the market. The beginning of globalization is marked by instability and occasional crises. The markets of shares, goods, estate and oil are instable. Financial bubbles always explode, simply because by definition a bubble consists of an unsustainable pattern of changing prices and money

GENTRIFICATION, CREATIVE CLASS AND PROBLEMS OF CONFLICT OF INTEREST IN CONTEMPORARY URBAN DEVELOPMENT

This paper considers modern city territories and analyzes neoliberal spatial city planning which is, among other things, mostly realized through gentrification. While explaining the modern transformation tendencies of cities the authors seek to find the link between the gentrification phenomenon and the rise of city inequality. In this context, marginality is not the result of economic underdevelopment but economic progress. The paper explores the reasons why contemporary urban politics leads to class segregation. The authors investigate a genetic connection of the capital and urbanization confirming Harvey’s paradigm that „capitalism is forced to urbanize in order to renew itself“. Furthermore, the paper investigates the relationship between creative class-creative city and to what extent it is reality and to what “a utopia for the chosen ones.

Unnecessary prescribing of antibiotics to healthy/asymptomatic school-age carriers of potentially pathogenic bacteria

Objectives: To re-draw attention to the unnecessary prescribing of antibiotics. ----- Methods: We monitored nasopharyngeal colonization by 3 potentially pathogenic bacteria, Streptococcus pyogenes, Streptococcus pneumoniae, and Haemophilus influenzae type b in 81 children between the ages of 6 and 7 years who attended the same primary school. The children's health status was also monitored, without using antimicrobial treatment for healthy/asymptomatic carriers. Nasopharyngeal swabs were collected on 6 occasions during autumn months, from mid-September to mid-December 2016. The children who fell ill during the study were treated at the Ear, Nose and Throat Clinic, Sisters of Mercy University Hospital Center, Zagreb, Croatia. ----- Results: Four hundred and sixty-three nasopharyngeal swabs were collected. Each child had at least one positive swab result. Bacterial colonization with Streptococcus pyogenes had the highest colonization rate. During the study, 83% of the children were healthy/asymptomatic carriers with no clinical signs of disease, while 17% became ill. The statistical results showed that the increase in all examined bacteria was statistically significant. ----- Conclusions: Our study results showed that positive bacterial findings in nasopharyngeal swabs from clinically healthy carriers were not an indication for antibiotic therapy

Application of Hybrid Density Functional Theory in Calculation of Edge-to-Face Interactions of Receptor-Ligand System

Our previously described research on docking analysis of a series of isosteric N4-arylpiperazines on a model of 5-HT1A receptor was used earlier to investigate interactions of different ligands with the receptor binding site. Due to the limitations of molecular mechanics (MM) methods, docking analysis failed to give precise results about interactions that influence binding affinity of the ligands, but we presumed that aromatic-aromatic interactions, or edge-to-face, to be more precise, play an important role in the binding process. In order to further elaborate on this hypothesis, ab initio approach was used to calculate possible edge-to-face interactions on a model system and correlate them to ligand affinity. Obtained results indicate that those dispersive interactions can show notable influence on the binding of the ligands to 5-HT1A receptor. Stabilization energies of modeled receptor-ligand complex, calculated using Becke's "half-and-half" hybrid DFT method showed strong correlation with the affinity of investigated ligands towards 5-HT1A receptor
