Transformacija domova za stare i novi strateški oblici u arhitekturi

The demographic features of Serbia are characterized by an intensive process of population ageing. At the same time, nursing homes are organizationally, conceptually and ecourbarchitecturally outdated, lacking in both accommodation capacity and the space necessary for all the residential functions. Therefore, it is high time a national effort was aimed at transformation of these facilities. The goal of this paper is to formulate different guidelines for establishing and defining a concept in designing new elderly care facilities and reconstructing the existing ones, as well as to introduce innovative forms of dwellings striving to keep the elderly in their homes as long as possible. The guidelines are a result of long-standing practice in developed countries around the world: the USA, Sweden, Denmark, the Netherlands and Finland

Медији и криминалитет - криминолошки аспект

The relationship between media and crime is a very complex and complicated problem that has not been systematically treated in our literature. It is undisputed that the media have a dominant influence on the shaping attitudes in public opinion on all important social issues, and so on crime as a negative social phenomenon. Most of the stereotypes and misconceptions about certain aspects of the criminal phenomenon are largely the result of the media image of these phenomena. The subject of the dissertation is exploration how media represents criminal phenomenon, assuming that there is exaggeration in coverage of violent crime that can affect the shaping of human behavior in a negative direction. In addition to violent crimes, taking into account the specificity of media coverage in the country, as well as public opinion regarding the problem of crime in general, the subject of the dissertation is also a study of the phenomenon of corruption. Inadequate media reporting on certain aspects of criminal phenomenon may result in the creation of moral panic that is by nature the most relates to the problem of violence, but the study has focused primarily on the moral panic that the media in Serbia, create in connection with certain forms of violent crimes such as domestic violence, pedophilia, rape or bullying of children and young people. The research topic is also the impact of media reporting on the courts in the context of conducting criminal proceedings because they are the most common in media reports. Also, inadequate reporting of a criminal incident can have serious consequences for the outcome of criminal proceedings. Bearing in mind that in work it is problematised three aspects of the media and crime (media construction of crime, media creation of moral panic and relationship between the media and the criminal justice) each are analyzed separately in part of the basic aim of the study which corresponds to the description and understanding of the phenomena. This is done by applying appropriate research procedures, methods, and associated research technique in the case of Serbia.Однос медија и криминалитета представља веома комплексну и сложену проблематику која до сада није систематски обрађивана у нашој литератури. Неспорно је да медији имају доминантан утицај на формирање ставова у јавном мњењу о свим битним друштвеним питањима, па тако и о криминалитету као негативној друштвеној појави. Већина стереотипа и погрешних схватања о појединим аспектима криминалног феномена су добрим делом последица медијске слике о овим појавама. Предмет дисертације је истраживање начина медијског представљања криминалног феномена, уз претпоставку да постоји пренаглашена покривеност насилничког криминалитета која може утицати и на обликовање људског понашања у негативном смеру. Поред насилничког криминалитета, узимајући у обзир специфичност медијског извештавања у нашој земљи, као и став јавног мњења по питању проблема криминалитета уопште, предмет дисертације је и истраживање феномена корупције. Неадекватно медијско извештавање о појединим аспектима криминалног феномена за последицу може да има настанак моралне панике која се по природи ствари највише односи на проблем насиља, па је истраживање усмерено претежно на моралну панику коју медији у Србији стварају у вези с појединим облицима насилничког криминалитета попут насиља у породици, педофилије, силовања или насилничког понашања деце и младих односно тзв. „вршњачког насиља“. Предмет истраживања је и утицај медијског извештавања на судове у контексту вођења кривичних поступака јер су они најзаступљенији у медијским извештајима. Такође, неадекватно извештавање о неком кривичном догађају може имати озбиљне последице по исход кривичног поступка

Temperature and Al3+ influence on electrophoretic mobility of porcine pepsin

The influence of temperature and different concentrations of Al3+ on pepsin electrophoretic mobility was investigated. The increase of Al3+ concentrations causes the decrease the electrophoretic mobility of enzyme. Also the increase of temperature induced the same effect. The influence of both temperature and Al3+ ion concentrations is additive.Physical chemistry 2006 : 8th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 26-29 September 200

Testing the toughness of polypropylene filled with glass powder

Svrha rada je da se polimerni otpad prikaže kao sirovina ili na drugi način iskoristljiv materijal dobijen djelimičnim razdvajanjem komunalnog otpada. U radu je obrađena mogućnost ponovne upotrebe polipropilena recikliranjem uz dodatak staklenog praha, sa stanovišta žilavosti usljed udarnog opterećenja. Ispitivane su standardne epruvete, napravljene od osnovnog materijala - polipropilena i uz dodatak 0%, 5%, 10%, 15%, 20%, 25% i 30% staklenog praha granulacije manje od 0,5 mm, kroz šest ciklusa prerade. Izmjerene vrijednosti dale su mogućnost formiranja obrazaca promjene žilavosti posmatranog materijala sa različitim sadržajem stranog tijela, kroz cikluse prerade, što može pomoći u daljim istraživanjima i analizama.The purpose of this paper is to show polymer waste as a raw material or otherwise usable material derived from a partial separation of communal waste. This paper describes the possibilities of polypropylene re-use through recycling with addition of glass powder, from the point of view of toughness caused by impact load. Standard test specimens, made of basic material - polypropylene, with addition of 0%, 5%, 10%, 15%, 20%, 25% and 30% of glass powder with granulation less than 0,5 mm, have been tested through six processing cycles. The measured values gave a possibility of forming patterns for changes of the observed material with different content of additives, through processing cycles, which can be helpful in further research and analysis

Modulation of Functional Characteristics of Mesenchymal Stromal Cells by Acellular Preparation of Porcine Hemoglobin

Exploring the potential usage of the acellular preparation of porcine hemoglobin (PHb) isolated from slaughterhouse blood as a cell culture media component, we have tested its effects on the functional characteristics of stromal cells of mesodermal origin. Human peripheral blood mesenchymal stromal cells (PB-MSCs) were used in this study as a primary cell model system, along with three mouse cell lines (ATDC5, MC3T3-E1, and 3T3-L1), which represent more uniform model systems. We investigated the effect of PHb at concentrations of 0.1, 1, and 10 μM on these cells’ proliferation, cycle, and clonogenic and migratory potential, and found that PHb’s effect depended on both the cell type and its concentration. At the lowest concentration used (0.1 μM), PHb showed the least evident impact on the cell growth and migration; hence, we analyzed its effect on mesenchymal cell multilineage differentiation capacity at this concentration. Even under conditions that induce a specific type of MSC differentiation (cultivation in particular differentiation media), PHb modulated chondrogenic, osteogenic, and adipogenic differentiation, making it a potential candidate for a supplement of MSC culture. Through a model of porcine hemoglobin, these findings also contribute to improving the knowledge of extracellular hemoglobin’s influence on MSCs in vivo

Kinetics of heat denaturation of pepsin in a strong acid media

Heat aggregation of pepsin, in a strong acid media; involve the stage of nucleation, and the stage of growth of aggregates. The initial parts of the kinetic curves of aggregation were followed via monitoring the increase of absorbance (A) and were linearized as {dA/dt; t} and {A; t 2 } functions. The slope of these curves is proportional to the product rate constant of reversible denaturation and the rate constant of growth of aggregates. Addition of Al3+ ions display a lag period whose appearance is caused by intramolecular predenaturational changes in the pepsin molecule.Physical chemistry 2004 : 7th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 21-23 September 200

Uticaj zeolita na hemijski sastav mleka kod krava muzara domaće šarene rase

Milk yield and milk chemical composition are largely affected by the quality of dairy cattle diet. The chemical composition of milk is dependent upon a large number of factors, including breed, diet, care, housing system, stage of lactation, etc. Milk composition is primarily a breed-specific trait. This study was conducted over a period of 15 months, involving Serbian Spotted dairy cattle. The experimental animals were assigned to three groups, each receiving different levels of supplemental zeolite. The control group comprised cows that received no zeolite supplement. Experimental Groups I and II were fed compound feeds supplemented with 4% and 2% zeolite, respectively. Milk samples were analysed for the contents of milk fat, proteins, fat-free solids and lactose, and density. The results obtained suggest that zeolite supplementation affects milk chemical composition, depending on the zeolite level present in livestock feed.Najveći sadržaj mlečne masti u mleku je izmeren kod krava I-O grupe 4,62%, zatim kod K-grupe 4,28% i najmanji kod II-O grupe 4,26%. Statistički signifikantnih razlika u sadržaju mlečne masti među grupama je bilo (P (lt) 0,05). Nivo proteina u mleku krava bio je u intervalu od 3,34% kod krava II-O grupe do 3,51% kod krava kontrolne grupe. Krave K-grupe imaju najveći prosečni sadržaj proteina u mleku ali i najveće varijacije u ovoj osobini. Na osnovu sadržaja proteina u mleku statistički značajnih razlika između grupa nije bilo (P>0,05). Prosečne vrednosti gustine mleka bile su u opsegu od 31,21% kod krava IIO grupe do 33,00% kod krava K-grupe. Kao i kod prethodne osobine i ovde je najmanja prosečna vrednost merene osobine bila kod krava II-O grupe (31,21), sa isto tako, najmanjim koeficijentom varijacije među grupama (3,01). Kod ove osobine uočene su statistički značajne razlike među grupama (P (lt) 0,05). Najveći sadržaj SMBM u mleku imale su krave K-grupe sa iznosom od 9,56%, a najmanju krave II-O grupe 9,11%. Najveće variranje ove osobine je kod krava K-grupe, a najmanje kod krava I-O grupe sa iznosom od 2,51%. Sadržaj SMBM u mleku pokazao je statistički značajne razlike (P (lt) 0,05). Sadržaj laktoze u mleku krava bio je u intervalu od 5,01% kod krava II-O grupe do 5,26% kod krava K-grupe. Krave I-O grupe imale su količinu laktoze koja se nalazila između ove dve grupe. Sadržaj laktoze u mleku krava između grupa pokazao je statistički značajne razlike (P (lt) 0,05). Dodavanje zeolita ('Tufozel') imalo je uticaja na hemijski sastav mleka kod ispitivanih krava muzara

Non-essential activation of pepsin by Al3+ “in vitro”

The in vitro effect of Al3+ ions on pepsin activity at pH 2, via kinetic parameters was evaluated. Kinetic study showed that Al3+ ions increase the maximal velocity (Vmax) rather than apparent affinity for substrate (KS) implying the non-competitive nature of activation which indicated that aluminium was a non-essential activator of partial non-competitive type.Physical chemistry 2008 : 9th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 24-28 September 200
