Introduction. Acute aortic dissection is an urgent surgical disease. Often, due to hemodynamic instability, that is an indication for emergent surgical intervention. Majority of surgeons uses Femoral or Axillary artery as arterial inflow site forextracorporal circulation. Both approaches have disadvantages that potentially may cause devastating complications. Some of them have been described in literature such as inadequate flow on heart- lung machine, retrograde dissection and malperfusion syndrome. Aim of study. Aim of study is to show, that by using transventricular cannulation we are eliminating all technical problems and lowering peroperative morbidity and mortality. Method: Between 1996 - 2006 at Institute for Cardiovascular Disease "Dedinje" 107 patients were operated for acute ascending aortic dissection Femoral artery was used for arterial cannulation in 91 patients. Last 16 patients were operated by using transventricular approach to establish extracorporeal circulation. We used retrograde cerebral perfusion in 21 cases at the beginning of our experience. Results. In group of patients where transapical cannulation was used, no neurological incidents were noticed. We didn't have any other problems related to extracorporeal circulation or placement of arterial cannula. Is this series we had only one death case. Patient passed away on eight postoperative day due to multiorgan insufficiency. Conclusion. Transapical cannulation is very simple and safe method for quick establishment of extracorporeal circulation. It always gives patient sufficient antegrade, physiological flow on heart-lung machine. This is the way to minimize possibility of malperfusion syndrome and to significantly diminish risk of neurological complication. By using this method all negative effects of other cannulation sites will be avoided.

Breast cancer is really one from tumor with highest mortality in this country as well as in the word. For early detection of the loco-regional breast cancer and disease confirmation, many diagnostic procedures were recommended with aims to help in decision for surgery treatment. This comparative study reported data by clinical analyses, ultrasonography, mammography and histological findings obtained after ex tempore biopsy, in 59 women with breast cancer aged from 16 to 69. The highest incidence of cancer was obtained in women over 61 years of age, although high rate of breast cancer was found in aging between 21 to 50 years. The fibroadenoma were founded in 40.68%, while malignant carcinoma ductale in 13.55% of all cases. Correlation between applied analyses for fibroadenoma was found in 86.05% cases, while in malignant lesions this percentage was highest (93.33%). Apart of these methods applied for early diagnosis in general hospital and obtained statistical significance in diagnosis, new techniques based on molecular level (hormone receptor status) must be used.

Published: December 2008

Vocal fold mass removal techniques were significantly modified back in 1970s by Hirano's laminar vocal structure and physiology of phonation works, as well as Titze's vibratory vocal cycle works. New methods were to come. Removing the lession by maximum preservation of vocal laminar microstructure (lamina propria and epithelium) and minimal damage of surrounding normal vocal tissue, was pointed out. Microflap technique is based on presenting the superficial layer of lamina propria with the lesion and removing the lession without damage of the mucosa. Preserving of the mucosal layer provides the shield for vibratory substructures. There are two elementary approaches for microflap: lateral and medial. Lateral microflap technique enables better identification of vocal ligament and lowers the risk of it's injury, particularly when scars and tightly adherent lessions are present. This technique has been used in case of big or diffuse lesions, such as vocal oedema or vocal lygament identification difficulties (e.g. vocal scarification). Medial microflap technique seems to be appropriate in removing smaller, localized lessions, such as cysts and vocal polyps. Our 45 patients experience is presented in this article , in 30 patients lessions were removed by lateral microflap technique (46 vocal cords in total), while 15 patients were treated by medial microflap technique. The outcome was assumed by endovideolaryngostroboscopic analysis of glottal occlusion and mucosal wave prior and following to the procedure. Reinke oedema management results were analysed separately.

Published: December 2008

Introduction: Chronic venous insufficiency (HVI) is manifested by the progressive signs of venous stasis. This disorder is treated by: compressive bandaging, medicaments, sclerotherapy, surgery, etc. Aim: Prospective study of the effects of semisynthetic diosmin (clinical signs, quality of life, local biochemical parameters) on patients with HVI to whom no other method of treatment has previously been administered. Method applied: This prospective study analyzed the presence of risk factors and personal history of 80 patients with HVI. Diagnosis of HVI was based on the clinical appearance and the color duplex scan. Each patient's clinical signs (pain, edema, feeling of heaviness and tightness in the lower leg), quality of life (physical, social, and psychological), and CEAP stage were assessed prior to and 30 days after the treatment with Phlebodia 600?. For 15 patients with unilateral varicose veins, local values of lactates and gas analysis were taken under the conditions before and following the static load, and venous control samples were taken from the healthy leg. The acquired data were processed by means of descriptive statistics, while the significance of nonparametric features was measured by Wilcoxon test. Results: HVI is somewhat more frequent among females than among mails, on the left than on the right leg, and at the average age of 52.3+ 10.5. The patients with HVI are basicly engaged in professions with static load and have positive family history. The patients mainly started medical treatment 12.5+8.6 years after the first symptoms of the disease. Clinical improvement was recorded on the state of 65/80 patients. After the treatment numerical values of some of the clinical signs were statistically lower compared to the values before the administration of semisynthetic diosmin: oedema (0.94:1.50), pain (1.10:1.84), feeling of heaviness (1.20:1.96), and tightness (1.14:1.78). After the administration of the tested medication, parameters of physical, social, and psychological quality of life were significantly improved (p<0,0001), accompanied with significantly improved (p<0,0001) CEAP stage of HVI (3.00:3.40). Local biochemical parameters had not been significantly changed. Conclusion: Administration of semisynthetic diosmin during 30 days results in significant improvement of clinical signs, quality of life and CEAP stage of HVI.

In Phoniatric Dpt. everyday practice we try to keep specific multidisciplinary approach to the communication disorders, that includes an expert team using modern technology. Over the last six years we have treated 110 singers (3% of all new cases) and the results of their diagnostic and therapeutic management are presented here. There were 67 women and 43 men, 41 were smokers and 69 nonsmokers. The singing genres included 24 pop, 41 folk, 8 ethnic, 29 choral and 8 opera singers. The therapy success was compared with the demographic parameters, level of education and music genres across the subjects. A precise history, clinical examination, endovideolaryngostroboscopy and multidimensional computer analysis of voice and speech was carried out by two phoniatricians, two logopeds, two nurses and one clinical psychologist. Additional consultations were carried out by audiologists, allergists, endocrinologists, chest physicians, gastroenterologists and neurologists where necessary. We suggest that the gold standard is conservative therapy, with phonosurgery if conservative measures fail. We also suggest that an annual systematic examination is optimal in preventing disease in professional singers.

Published: December 2008

Fractures, and especially pseudoarthroses of the scaphoid bone, are a great problem in orthopedic surgery, because the failure percentage is remarkably high (20- 30%) even with the top modern treatment methods. Use of grafts, especially well-vascularized ones, along with good fixation, has improved treatment outcomes, but the failure and complication percentages remain high. In the pilot study, we present the first five patients with the pseudoarthrosis of the scaphoid bone, male, of 26.8 years of average age (from 22 to 34 years old), in whom the method of extrafocal fixation, with distraction and compression, was applied. The fracture healing was achieved in all patients after an average period of 87 days (from 60 to 100 days), with the healing time also including a minimum of a month of physical therapy, after the fixator was removed. The result was evaluated using the Mayo wrist score, and from the preoperative 26 points, 82 points were achieved.

The use of psychoactive substances causes various consequences and is harmful for all organs. Some of the health consequences among intravenous drug users are HIV infections, hepatitis C, local tissue infections after drug injection, family, professional and social consequences. Through the world various harm reduction programs are established in order to educate drug users about safer drug injecting techniques, with the use of sterile needles and materials for disinfection of the drug injecting area. Authors presented epidemiological data, consequences on extremities after non sterile drug injecting and accidental burns, harm reduction programs as well as other guidelines in this field. In three case reports of intravenous drug addicts with surgical complications on the extremities and burns, surgical and anaesthesiological approaches were described. Special emphasis was given to preoperative preparations and the postoperative treatment as well as social- psychiatric aspect.

Foreign bodies of the nose are relatively frequent in pediatric population, while in the adults, they are usually seen in disturbed persons. Overlooked nasal foreign bodies may be singled out as a special entity. They become rhinolites over time with latent period of several decades. Our paper illustrates an overlooked foreign body in the nose - i.e. encrusted plastic bead which, after the asymptomatic period of 48 years, induced the unilateral mucopurulent and ichorous secretion from the nose. Rhinolite should be suspected if radiological diagnostics detected calcified mass in the nose together with unilateral nasal symptomatology. Surgical removal of rhinolite results in complete management of such problem. This case indicates the significance of medical history data and examination of nasal cavity in any adult patient with unilateral nasal symptomatology which is refractory to conservative treatment. Computerized tomography of paranasal sinuses is an important adjunct diagnostic tool in indefinite cases. Nevertheless, it often happens that only the extraction of rhinolite indicates the diagnosis that is not usually suspected in adult persons.

Published: December 2008

Methylene blue is a dark green crystal. In medicine it is used as water or alcohol solution. Methaemoglobinemia, hypotension, septic shock are some of many diseases that are treated with methylene blue. In surgery methylene blue is used in diagnostic procedures such as a fistula detection or detection of the parathyroids glands, and for the delineation of certain body tissues during surgery. In patient with normal renal function methylene blue is appearing in urine in a few minutes after intravenous administration. In our patient who was 70 year old we remarked interesting phenomena after we instillation methylene blue into the fistila channel during local treatment of hip osteomyelitis. Methylene blue appeared in urine two days after local treatment, coloring the urine light green and color elimination time was prolonged in few days. These parameters induced as to suspect in renal failure. That was proved after urological, laboratory and radiology examination.

Published: December 2008

The object of the study was to investigate the process conditions relevant for the pentyl octanoate production with the lipase from Candida rugosa immobilized on Sepabeads EC-EP carrier. This is an epoxide-containing commercial polymethacrylic carrier with suitable characteristics for enzyme immobilization. The immobilized lipase suitable for pentyl octanoate synthesis has been prepared by a direct lipase binding to polymers via their epoxide groups. The enzymatic activity was determined by both hydrolysis of olive oil in an aqueous system and esterification of n-pentanol with octanoic acid in a low aqueous system. The influence of several important reaction parameters such as temperature, initial water content, initial substrate molar ratio, enzyme loading and time of adding of molecular sieves in the system is carefully analyzed by means of an experimental design. Production of the ester was optimized and an ester production response equation was obtained, making it possible to predict ester yields from known values of the five main factors. Almost complete conversion (>99%) of the substrate to ester could be realized, using lipase loading as low as 37 mg/g dry support and in a relatively short time (24 h) at 45?C, when high initial substrate molar ratio of 2.2 is used.
Vibrations of cracked reinforced and prestressed concrete beams
Authors: Huszár Zsolt
Published: December 2008

The dynamic behaviour of bent reinforced concrete beams in elastic range is significantly influenced by cracks caused by former loads. Considering this fact a more accurate calculation of the eigenfrequencies of the beams is available. Experiments have shown that the features of vibration differ from the results obtained by the well-known linear model, if cracked zones exist. The cause of this phenomenon is that the bending rigidity of the cross-sections in the cracked range depends on the sign of the actual bending moment. Therefore the vibration shows non-linear characteristics in the elastic range as well. The dynamic behavior of bent prestressed concrete beams is similar. The dynamic characteristics of prestressed beams besides cracks is influenced also by the intensity and eccentricity of the axial force. For a detailed investigation of the problem, experiments and non-linear analysis were performed. On the basis of these the virtual eigenfrequencies of the non-linear vibrations were determined.

Virtuality in architecture: From perspective representation to augmented reality
Authors: Cahtarevic Rada
Published: December 2008

Notion of virtuality correlates mainly to visual aspects of space, presuming that basic qualities of physical space can be simulated by graphics, providing not just visual illusion of the third dimension of real space, but psychological involvement and transfer of the spectator into the space of the picture, giving him the sense of the spatial location and presence. Creation of virtual space that could be perceptually sensed and by virtual presence modified and shaped, explored and experienced, is not just result of advanced computer technology, but could be traced through history of spatial representations, that was based mainly in artistic and architectural practice. Architecture, being leading field that synthesize representation, construction and sense of spatial creation, had to be involved in explorations of multidimensional complex network of dynamic informational space, that is revealed in its real and virtual dimension as unique universe. Real-time experience in virtual space allow access in the alternative dimension to every open mind, giving him possibilities to play and work, to construct and represent, search, explore and express, augmenting reality into the complex network of information flow between visible and invisible space.

Published: December 2008

The goal of this paper is to test the topical and possible application of sustainable development principles in the protected areas. The sustainable development is observed as a goal and the flexible mechanism for reaching the consensus set by the fundamental postulates of the Agenda 21, among all the relevant factors in the decision making and enforcement of regulations. It is unquestionable that the spatial planning possesses the necessary integrative potentials for management of changes, long term time horizon and the catalytic position in reconciliation of public, social and private interest. The road towards sustainability is a long and complex process, because it requires the change of the way of thinking and behavior of all the social factors, that is, establishment of the understanding the environmental effect of the development is as important as the economic one. The main guidelines of this reconciliation must be the vision and the aims of preservation of natural resources, but not as the ultimate requirement of the authorities, but as the argument-supported and articulated public interest. This paper refers to the Spatial plan of the special area of Sicevo gorge through the review of basic regimes of natural resources protection, restrictions and prohibitions. It also pays attention to the measures which will allow to achive sustainability of development as well as apply protective regimes.
Complex analytic signals applied on time delay estimation
Authors: Velickovic Zoran , Pavlovic Vlastimir
Published: December 2008

In this paper, we present the concept of the time delay estimation based on the transformation of real sensor signals into analytic ones. We analyze the differential time delay values obtained using real seismic signals, simulated complex analytic signals and simulated complex analytic signals with real parts coming from real seismic signals. The simulation results indicate that the application of complex analytic signals leads to reliable computation of the differential time delay. The influence of specific signal parameters on spectral coherence threshold in systems for passive localization and proposed methods for lowering the threshold is analyzed. The computation of all differential time delays with respect to the reference sensor (geophone) is based on the application of Generalized Cross-Correlation (GCC) applied on corresponding analytic signals. The difficulties to select a peak of cross-correlation function that corresponds to true differential time delay when dealing with real signals are significantly reduced if GCC is applied on analytic signals. The efficiency of the proposed technique on differential delay estimation is performed on deterministic and real-life signals.
Gerade-ungerade symmetry breaking in HD: States close to N=2 dissociation limit
Authors: Grozdanov Tasko
Published: December 2008

We review the consequences of the gerade-ungerade symmetry breaking in HD molecule. A particular attention is devoted to electronic states close to n=2 dissociation limit. The effects of the breakdown of the Born-Oppenheimer approximation are discussed. For the description of the molecular dynamics the formulation of the coupled-sates method is given. The method is applied to calculations of loosely bound states in the outer well of the II'1?g potential. The results are in excellent agreement with experimental data and calculations based on a semi-empirical potential.
The determination of low energy electron-molecule cross sections via swarm analysis
Authors: Dujko S. , White R.D. , Petrovic Z.Lj.
Published: December 2008

In this paper we discuss the swarm physics based techniques including the Boltzmann equation analysis and Monte Carlo simulation technique for determination of low energy electron-molecule cross sections. A multi term theory for solving the Boltzmann equation and Monte Carlo simulation code have been developed and used to investigate some critical aspects of electron transport in neutral gases under the varying configurations of electric and magnetic fields when non-conservative collisions are operative. These aspects include the validity of the two term approximation and the Legendre polynomial expansion procedure for solving the Boltzmann equation, treatment of non-conservative collisions, the effects of a magnetic field on the electron transport and nature and difference between transport data obtained under various experimental arrangements. It was found that these issues must be carefully considered before unfolding the cross sections from swarms transport data.
Low-energy electron driven processes in ices: Synthesis reactions and surface functionalization
Authors: Martin I. , Amiaud L. , Azria R. , Lafosse A.
Published: December 2008

Low-energy electrons, and subexcitation energy electrons in particular, have the ability to induce efficiently chemical modifications within condensed molecular films and at substrate surfaces. By taking advantage of the Dissociative Electron Attachment (DEA) process, which leads to selective bond cleavages, the induced reactivity can be controlled solely by the electron energy. Two illustrative examples of induced reactivity and substrate functionalization achieved by low-energy electron processing of condensed molecules studied by means of High Resolution Electron Energy Loss Spectroscopy (HREELS) are reviewed, and special interest is given to the possibility of proposing overall reaction mechanisms. The resonant decarboxylation reaction in condensed films of trifluoroacetic acid CF3COOH induced by electrons at ~1 eV involves the formation of the transient species [CF3COOH]#- and the further formation of CO2 by a concerted mechanism. Diamond substrate functionalization by CH2CN organic groups through Cdiam-C and Cdiam-N bonds is performed by 2 eV electron irradiation of condensed acetonitrile CH3CN and involves reactants formed by DEA, that are neutral radicals H? and molecular anions [H2CCN]-.

Published: December 2008

The Getic and Supra-Getic are palaeogeographic units in SE Serbia and SW Bulgaria. Based on the presence (in Eastern) or absence (in Western) of Lower Jurassic marine deposits, the Getic is divided into Eastern and Western. In the Eastern Getic, the Lower Jurassic sedimentation in SE Serbia is represented by the Vidlic Clastites covered by the Lukanja Coal Beds, Lukanja Quartz Sandstones, Lukanja Brachiopods Beds, Lukanja Marlstones, Lukanja Belemnitic-Gryphaean Beds and Lukanja Cephalopod Limestones; in SW Bulgaria, the sedimentation commenced with the Tuden Formation, followed by the Kostina Formation and the Ozirovo Formation with a few members. The Middle Jurassic in SE Serbia commenced with the Senokos Siltstones and Shales and the Gulenovci Beds, while in SW Bulgaria with black shales (the Etropole Formation), followed by marls and clayey limestones of the Bov Formation. The Middle Jurassic sediments are represented in the Western Getic of SE Serbia by the Kurilovo Clastites and the Kurilovo Limestones (synonym to Gumpina Limestones of KRA?TNER & KRSTIC 2003); in the Supra-Getic of SE Serbia they are formed by the Jerma Clastites and Jerma Limestones (synonym of the Gumpina Limestones). In SW Bulgaria the Middle Jurassic sediments are represented by the sandstones of the Gradets Formation and by the bioclastic limestones of the Polaten Formation. During the Callovian (Middle?) started the formation of a carbonate platform with micritic limestones. In SE Serbia, it is Basara Limestones, Vidlic Limestones, Beljanica and Zdrelo Limestones, and in SW Bulgarian, the Belediehan Formation of Callovian-Kimmeridgian p.p. age. Characteristic for the Supra- Getic is the formation of a few grabens with specific sedimentation: the Svetlya Graben (the Zhablyano and Ozirovo Formations) and the Lobosh Formation; the Treklyano Graben (the Dobridol and Sredorek Formations), and out of it - the Methohya and Sredorek Formation. During the Callovian-Kimmeridgian p.p., in the Svetlya Graben was sedimented the Lobosh Formation, horizontally passing into the Javorets and Gintsi Formations. During the latest Kimmeridgian-Tithonian commenced a big facial diversification: on the Getic in SE Serbia sedimented reef or sub-reef limestones (the Crni Vrh and Kucaj Reef Limestones), while in SW Bulgaria, the Slivnitsa Formation. On the Supra-Getic in SE Serbia formed Luznica Flysch and in SW Bulgaria pre-flysch of the Neshkovtsi Formation and siliciclastic flysch of the Kostel Formation.

Published: December 2008

Quality protein maize (QPM) contains the opaque-2 gene along with numerous modifiers for kernel hardness. Therefore, QPM is maize with high nutritive value of endosperm protein, with substantially higher content of two essential amino acids - lysine and tryptophan, and with good agronomical performances. Although QPM was developed primarily for utilization in the regions where, because of poverty, maize is the main staple food, it has many advantages for production and consumption in other parts of the world, too. QPM can be used for production of conventional and new animal feed, as well as for human nurture. As the rate of animal weight gain is doubled with QPM and portion viability is better, a part of normal maize production could be available for other purposes, such as, for example, ethanol production. Thus, breeding QPM is set as a challenge to produce high quality protein maize with high yield and other important agronomical traits, especially with today's food and feed demands and significance of energy crisis.

Published: December 2008

Popping volume and yield are traits caused by several heredity factors. It is difficult to obtain superior genotypes for both traits but it is possible to develop genotypes with good popping volume and satisfactory yield. The hybrid ZPPL2 x ZPPL5 was superior in yield, heterosis and SCA for both yield and popping volume. As inbred ZPPL4 in all combinations has a good value for popping volume could be concluded that this inbred may be used as parent in further crosses. Analysis of variance of the combining ability indicating significant SCA effect for grain yield, and significant both GCA and SCA effects for popping volume. Therefore it can be stated that yield is influenced by non-additive and popping volume by both additive and non- additive gene effects. Analysis of variance of genetic components for popping volume indicates that the additive as well as dominant components significantly affected the inheritance of this trait in popcorn. The objective of this study was to evaluate heteorsis and combing ability for grain yield and popping volume in dialalel set of six maize inbred lines.

Authors: Dimitrijevic Miodrag , Petrovic Sofija , Gustafson Perry
Published: December 2008

A sample of 139 varieties of common wheat (Triticum aestivum L.), predominantly Serbian winter wheat varieties originated in the Institute of Field and Vegetable Crops in Novi Sad, has been examined for presence of 1BL/1RS wheat-rye translocation. Two genotype groups consisted of varieties possessing and lacking the translocation have been compared. Stem rust, leaf rust, powdery mildew as well as, winter hardiness were studied. The influence of 1BL/1RS translocation was also studied in a light of wheat seed storage protein (glutenin and gliadin) genetic background composition. Genotypes having the translocation appeared to be more tolerant to stem rust, and leaf rust, but more susceptible to powdery mildew. These effects were slightly modified depending on the examined genetic background, but the effect of the rye 1RS translocated chromosome arm was the main cause for the observed differences.

Published: December 2008

The determination of Exserohilum turcicum virulence factors and resistance responses of three sets of maize inbred lines (four differential, eight isogenic and 22 commercial inbreeds) to three isolates of this pathogen under greenhouse conditions were studied. The maize inbreeds were selected according to previous testing of resistance based on lesion types in 194 inbreeds under field conditions of plant inoculation with the E. turcicum race 0 (designated as the isolate MRI-Et). The standard procedure was applied to obtained isolates MRIZP-1747 and MRIZP-1416 from resistant and susceptible lesion types, respectively. These lesions were developed on the same leaf of a plant of the experimental hybrid no. 163/99 grown in a nursery at Zemun Polje during 1999. The third isolate (MRIZP-1435) was isolated from a leaf sample originating from the location of Srbobran in which the occurrence of northern corn leaf blight (NCLB), caused by Exserohilum turcicum, was intensive. Based upon virulence/avirulence of three isolates of E. turcicum on differential maize inbred lines, it was found out that the isolate MRIZP-1747 could be classified as race 0, whereas isolates MRIZP-1416 and MRIZP-1435 could be classified as race 1. These are the first results that confirm the presence of race 1 of E. turcicum in Serbia. Not including differential lines, 22 and six lines were resistant to race 0 and race 1, respectively, while eight and five lines were resistant and susceptible to both races, respectively. All isogenic lines not containing the Ht gene were susceptible to both races 0 and 1.

Sweet maize differs from maize of standard grain quality by many important traits that affect the ear appearance, and especially by traits controlling taste. The ear appearance trait encompasses the kernel row number, configuration, row pattern (direction and arrangement), seed set, kernel width and depth, ear shape and size. The quality of immature kernels is controlled by genes by which sweet maize differs from common maize. In order to obtain high-ranking and high-quality yields, it is necessary to provide the most suitable cropping practices for sweet maize hybrids developed at the Maize Research Institute, Zemun Polje. The adequate sowing density is one of more important elements of correct cropping practices. The objective of the present study was to determine the effect of four sowing densities in four ZP sweet maize hybrids of different FAO maturity groups on ear qualitative traits and yields obtained on chernozem type of soil in Zemun Polje. The observed traits of sweet maize (ear length, kernel row number, number of kernels per row, yield and shelling percentage) significantly varied over years. The higher sowing density was the higher yield of sweet maize was, hence the highest ear yield of 9.67 t ha-1 , on the average for all four hybrids, was recorded at the highest sowing density of 70,000 plants ha-1. The highest yield was detected in the hybrid ZP 424su. The highest shelling percentage (67.81%) was found in the hybrid ZP 521su at the sowing density of 60,000 plants ha-1. Generally, it can be stated that sweet maize hybrids of a shorter growing season (FAO 400) could be cultivated up to 70,000 plants ha-1, while those of a longer growing season (FAO 500) could be grown up to 60,000 plants ha-1. In such a way, the most favorable parameters of yields and the highest yields can be obtained.

Because proximity measures occur in pairs where both, similarity and dissimilarity measures exploit the same type of information, companion classification and ordination techniques can be applied. They complement each other in analysis of genotype by environment interaction (GxE) data. Choice of method, companion diagnostics and graphical presentation are required within each of methodologies. By clustering of 12 genotypes into 5 groups, 96.26% of variability for genotypes contained in original data is kept. By applying same analysis for environments, 96.45% of variability contained in original data matrix is kept with grouping of 31 environments into 11 groups. Caused by genotypes and environments grouping 78.10% of GxE variability contained in original data matrix remained in analysis of such two-way reduced data. Based on shown results, it is not possible to define smaller growing regions. Clustering of environment can be useful not only for defining mega environments but also for smaller growing regions defining only in combination with some of additional analysis (AMMI, discrimination analysis, correspondent analysis etc.). In such kind of analysis experience of investigator would be of great importance. Choice of test sites for breeding programme can be made based on obtained grouping to a limited extent (rather for restructuring existing test sites network in order to obtain 'better' information with same number of test sites then for its rationalization with number of test sites decreasing).
Highways, roadblocks and empires
Authors: Hayden Robert
Published: December 2008

'Building the Balkans' requires the construction of infrastructures, especially highways. In this paper, I look at the construction and obstruction of highway systems in the Balkans as concrete manifestations of metaphors of incorporation and separation. While the infrastructure is mainly tangible, the roadblocks, largely due to ideological positions, are often intangible but very real, and are created as much by the European Union and the US as by the peoples of the Balkans themselves. The basic argument is that infrastructures connect people better than ideologies do, and that putting 'values' before more practical linkages (which both the EU and the US are doing) hinders the establishment of normal links between the Balkans peoples. Finally, I add a few words of anticipatory nostalgia for Balkans diversity that may well be threatened by the region's incorporation into the unifying structures, and ideologies, of the European Union.
Nostalgia matters: Nostalgia for Yugoslavia as potential vision for a better future
Authors: Palmberger Monika
Published: December 2008

Nostalgia for Yugoslavia is a social phenomenon which prevails in present-day Mostar as well as elsewhere in the Yugoslav successor states. Even if attempts are made by the elites of local politics to erase traces of the Yugoslav past (especially in Croat dominated West Mostar), a good part of Mostar's population still nostalgically remembers that period. Until recently, nostalgia has been neglected as a subject of research in the social sciences and has been acknowledged - if at all - only as a phenomenon oriented towards the past. Recent studies, however, have emphasized a utopian character of nostalgia. It is particularly interesting to further investigate this aspect in the context of post-socialism. This paper discusses the selected narratives of two women whom I encountered during my fieldwork conducted between 2005 and 2008, and their relationship to Yugoslavia. It is shown that differences in their narratives can be related to their nationality and family backgrounds, but to the same degree - if not more so - to their age and the stage in life they are in. At the end of the paper I shall tackle the question whether nostalgia for Yugoslavia can hold as a potential vision for a better future and, if so, under which conditions.
The rights and duties of post-adolescent daughters: Daughters' and parents' accounts
Authors: Kuhar Metka
Published: December 2008

The article deals with the conceptualisation and negotiation of post-adolescent daughters' rights and duties in their families of origin. More and more young Europeans and particularly many young Slovenians are staying with their parents in the post-adolescence period (and even later) or come home from their university city every weekend. This means that two adult generations live together in the same household; so they have to negotiate the rights and duties of the younger generation in different areas, from very personal domains (e.g. appearance) to more far-reaching life decisions (e.g. the post-study life situation, moving out of the parental home). The study provides at least a partial insight into the processes involved in the negotiation of rights and duties in families with post-adolescent daughters. The data stem from semi-structured interviews conducted in autumn 2006 in Slovenia with 70 first-born post-adolescent girls and both of their biological parents. The respondents answered closed- and open-ended questions referring to four vignettes suggesting controversial situations. The answers allow a view of the conceptualisations of post-adolescents' rights and duties, the distribution of decision-making power and the way of dealing with such situations. The results show that post-adolescent daughters are very dependent on their parents in various areas. It turned out that the contemporary Slovenian family with post-adolescent daughters is prepared to negotiate: patterns of intrafamilial communication range from the traditionally grounded commanding pattern where children have to obey unequivocally (but less than 10% of parents resort to the bare use of authority), to an open, active negotiation pattern where the balance of power is more equal and the achievement of consensus is very important.
Perception of victim treatment by police and courts: A study among university students in India and Japan

Previous research has established that the perception of victim treatment is influenced by a number of factors such as socio-demographic characteristics, economic status of the people, prior victimization and so on. Against this background, a study was conducted to examine the factors influencing the perception of victim treatment by police and courts. Data were collected using a structured questionnaire from a sample of 725 students from the city of Chennai (India) and 715 students from the city of Mito in Japan. The results revealed that while some of the factors such as gender, age, religion and community of the respondents have significantly influenced the perception of victim treatment, the effects of place of stay, nativity and income on the perception of victim treatment were not found to be significant.

Published: December 2008

This paper presents an on-going research project that aims to identify possibilities for wider use of evaporative cooling in process industry, especially the use of evaporative fluid cooler units. Experimental study is performed on small scale evaporative fluid cooler, while the correlation based model has been carried out to explore the detailed heat and mass transfer processes inside this unit. Numerical integration of mathematical model is executed by new approach, based on differential, collocation Simpson method. Proposed models have been verified by comparing the computed results with those obtained by the experimental measurements. The results of research will enable the creation of more comprehensive simulation software, with wider range of operating and construction parameters.
