Financing of current account deficit in new member states and Croatia
Radmila Jovanevi
Zbornik Radova Ekonomskog Fakulteta u Rijeci : ?asopis za Ekonomsku Teoriju i Praksu , 2008,
Abstract: The aim of this paper is to analyze the transition results in the countries of the last wave of accession to the European Union. After they joined the EU, the average productivity growth dropped in the fi rst year, but later this was overcome. While the rate of GDP growth rose in most NMS countries, current account deficits remained very high and foreign direct investments were not capable of covering current account defi cits in all NMS countries. Both the rising external debt in many NMS countries and the accumulation of household debts resulting from fast credit growth create a risk in most countries. The comparative analyses show that some governments need to work at sustainable economic policies to keep infl ation under control and reduce external vulnerability. The conclusion of the paper is that regardless of the availability of EU funds, national investment policy will have considerable impact on the real growth of the economy.
Authoritarianism as an element of social character and a factor of gendered social interaction

Filozofija i Dru?tvo , 2003, DOI: 10.2298/fid0323171j
Abstract: The immediacy of daily encounters with gender roles, as well as the specific features of authoritarian mediation in their social shaping, make an analysis of gendered social interaction indispensable. In this paper the analysis is centered on the concept of social character, with special emphasis on authoritarianism as a continuous determinant of the transformation of natural sex into social construct of gender. It is precisely the authoritarian personality type that is the basis for alienated gender, dominated by sexism, a “natural” belonging to the private or the public sphere of social life, suppression of individual human capacities, and reduction of choice. After a review of the theoretical conceptions of social character and authoritarianism, a historical-comparative analysis of authoritarianism is offered, where the latter is seen as an element of the social character within the perspective of the typology traditional - modern - postmodern society. It is argued in conclusion that, in spite of certain emancipatory achievements, men and women still tend to escape into the security of authoritarian alienation. Feminist theory remains a basic source for reflecting on these processes; therefore the author pleads for a wider acceptance of feminist insights as contributions to establishing a postmodern, interpretive “sociology in a new key”.

Glasnik Srpskog Geografskog Dru?tva , 2011, DOI: 10.2298/gsgd1103091k
Abstract: ajka ka is a geographical region in Serbia. It is southeastern part of Ba ka, located in the Autonomous Province of Vojvodina. ajka ka is characterized by suitable tourist-geographical position, a plenty of natural values and various cultural-historical inheritance. These characteristics enable a lot of opportunities for developing sports and recreational activities This paper presents the results collected in the field research about the attitudes of local people about opportunities for development sports-recreational tourism in ajkaska, as well as involving local community in this process. Initially, the survey was carried in Sajkaska and provided data about the participation of the local communities in the sport tourism development in Sajkaska Involving local community in this process is most easily done through the development of different forms of sports-tourist movements and tourism education programs of local population of ajka ka. As long as sport tourism development in Sajkaska is well planned and monitored, it can be an effective means of local economic growth, cultural affirmation and environmental protection without compromising a region’s unique attractions.
Epistaxis in patients with hereditary hemorrhagic teleangiectasia

Medicinski Pregled , 2006, DOI: 10.2298/mpns0610443j
Abstract: Introduction. Spontaneous recurrent epistaxis is the most common clinical manifestation of hereditary hemorrhagic teleangiectasia (HHT). It occurs in more than 90% of HHT patients and is the most distressing symptom. Nasal teleangiectasias tend to increase with age both in size and number, so epistaxis is heavier and more frequent. For patients with mild to moderate disease, there are many adequate treatment options. For those with severe disease, most treatments offer just a hemorrhage-free interval. Experienced otorhinolaryngologists who treat epistaxis in these patients often use the adage "to do as little as possible for as long as possible". Management of acute epistaxis. The recommendations for the management of acute epistaxis include: compression, use of topical antifibrinolytics, laser therapy, argon plasma coagulation therapy, fibrin sealant spray or gelatin sponge soaked in adrenaline. In cases of heavy acute epistaxis, an epistaxis balloon combined with artery ligation and/or embolization is the most effective treatment. Nasal packing and electrocauterisation should be avoided to prevent further trauma to the blood vessels. Treatment of recurrent epistaxis. Management of recurrent epistaxis includes topical application of laser energy (argon, Nd: YAG, KTP/532 and diode, not CO2), argon plasma coagulation in combination with 0.1% estriol ointment, caustics, antifibrinolytics, bleomycin and sclerosing substances. Systemic estrogen-progesterone at doses used for oral contraception may eliminate bleeding in women with heavy epistaxis. Systemic antifibrinolitics (used with extreme precaution) and septal dermoplasty give good results. The only method which successfully and permanently solves the problem of severe refractory epistaxis in hereditary hemorrhagic teleangiectasia is closure of the nasal cavities. .
The voice of patients with laryngeal carcinoma after oncosurgery

Abstract: The voice of patients indicated for surgical procedures in treating of dysphonia is already damaged before the operation. The problem, which exists at the level of glottis patients usually try to solve by compensative mechanisms. The quality of voice after the interventions in larynx depends on the type and width of resection, disturbance of physiological phonation mechanisms, and ability to establish optimal phonation automatism. The damage of laryngeal structure, especially its glottic part and vocal cords as its central part, no matter if they are just fibrous or they are partially or totally absent, leads into the development of substitutive phonation mechanisms. The most frequent substitutive mechanisms are: vestibular, ventricular, and chordoventricular phonation. There are some variations of these phonation mechanisms, which are conditioned not only by applied surgical technique, but as they are also individual characteristics, they can be the consequence of applied rehabilitation methods. The diagnosis of voice condition before and after the oncosurgical procedure is done by: laryngostroboscopy, subjective acoustic analysis of voice, and objective acoustic analysis of voice (sonography or computer analysis of acoustic signal). The most of laryngeal carcinomas appear in glottic region, so the function of phonation imposes itself as the objective parameter to measure the quality of life after the oncosurgery of larynx. That is the reason why according to the priority, it is just behind the principle of "oncologic radicalism". Phonation as the most complex laryngeal function seems to have secondary importance. All known operative techniques, especially partial resections, have the preservation of phonation as their goal.

Abstract: The basic applicability of the UPD theory of Gerischer et al. has been confirmed in the case of lead and thallium deposition on copper and silver single crystals, but it was shown also that this is only one of the important factors. It was established that the effect of substrate structure on the mechanism of the UPD monolayer formation plays an important role in the addition to the effect of electronegativity difference between the substrate and depositing atoms. An effect of changing the concentration of depositing metal and specifically adsorbing anion were found and attributed to the changes in the electronegativity of the substrate and underpotential layer as a result of changing the electrode potential. It was conclusively proven by the analysis of the peaked current-time transients obtained by potential step measurements and the very sharp voltammetry peaks, that first order 2D phase transformations are possible in UPD systems. It was also found that the L.S.V. peaks reflecting such processes must not be expected to be free from the influence of slow kinetics. It was established that the 2D crystalline metal-like phases with the closest-packed epitaxial structure exist as a stable, final product in UPD. Moreover, the possibility of higher order 2D transformations in UPD has been given strong support by the evidence of gradual monolayer density change with increasing driving force. Lead UPD on vitreous carbon was found to be the result of substrate reconstruction induced by the repeated deposition and dissolution leading to surface condition changes favoring deposition of the first layer. UPD monolayers on copper and silver surfaces always preceded OPD and had a profound effect on its nucleation overpotential (making it very small indeed) or even changing its character from 3D into 2D (in the case of vitreous carbon substrate). It was also shown that lead and thallium OPD on copper and silver single crystals starts off by charge transfer controlled instantaneous 3D nucleation and subsequent growth of 3D centers. Finally, the results obtained in the experiments performed have shown that electrochemical techniques can prove very suitable in the study of 2D phase transformation kinetics and that their further employment in this field should prove particularly rewarding.

Abstract: The over potential deposition of thallium onto carefully chemically polished single crystal copper (111), (110) and (100) electrode from sulfate and perchlorate solutions have been investigated using single and double potential step techniques. It appears that the different anions used did not change the current-time response characteristics significantly. The charge corresponding to UPD monolayers of thallium (≈210·10-6 Ascm-2 for the first, and ≈400·10-6 Ascm-2 for both, first and second, monolayers on all three orientations of the copper substrates used) were observed under the initial falloff seen on the current-time transients obtained at very short times, preceding the currenttime relationships for the overpotential deposition. Indication of a rising i-t transient reflecting bulk thallium deposition on Cu(111) and Cu(100) were usually observed at η=-9mVvs.Tl while an over potential of η=-10mVvs. Tl was needed for similar effects on Cu(110). The observed i vs. t2 linearity is characteristic to 3D instantaneous nucleation and further growth of 3D centres. The results show no appreciable 3D nucleation occurring until the UPD monolayers were completed. It must be concluded, therefore, that thallium over potential deposition on copper single crystal surfaces starts with a charge transfer controlled 3D instantaneous nucleation and proceeds by 3D growth. After some time the individual 3D centres overlap and the rate of increase of current falls off until finally the limiting current is reached. Similarly to the cases of lead deposition on Ag18 and Cu30 crystals, bulk deposition of thallium commences only after the two UPD close-packed thallium monolayers have been completed on the underlying substrate. Formation of the two UPD thallium close-packed monolayers, in the case of copper (111), (110) and (100) substrates, is an essential precursor to thicker thallium deposits their influence on the initiation of the over potential deposition and its growth mechanism, was shown to be very significant.

Abstract: The underpotential deposition and dissolution of thallium onto carefully chemically polished single crystal copper (111), (110) and (100) electrode surfaces from acetate, sulphate and perchlorate solutions have been investigated using single and double potential step techniques. It appeared that the different anions used did not change the current-time response characteristics significantly. Current-time responses to the potential steps applied strongly resemble those observed in the case of thallium underpotential deposition on silver single crystals [1]. The characteristics of i-t transients obtained by single potential step suggest very fast 2D crystal growth processes taking place. Sharp linear voltammetry peaks, which are observed for both thallium and lead deposition on Cu(111) [3,8] and on Ag(111) [1,3], probably always indicate nucleative phase formation processes but the rate of the lattice growth step will vary from system to system. Comparison of the obtained results with those for lead underpotential deposition [8-13] on Cu(111), (110) and (100) suggests that, in the present case, the rate of the 2D lattice building process for both thallium underpotential monolayers formed on three copper single crystal surfaces examined is so fast that it becomes controlled by diffusive processes; this will probably be surface diffusion [24,25] initially and, at longer times planar bulk diffusion. Double pulse experiments did not help significantly in attempts to obtain i-t transients capable of providing data suitable for showing conclusively the occurrence of 2D crystal formation processes. A similar situation occurred also with silver substrates [1].

Abstract: We report on the study of the intensities of several gamma lines emitted after the inelastic scattering of neutrons in $^{56}$Fe. Neutrons were produced by cosmic muons passing the 20t massive iron cube placed at the Earth's surface and used as a passive shield for the HPGe detector. Relative intensities of detected gamma lines are compared with the results collected in the same iron shield by the use of $^{252}$Cf neutrons. Assessment against the published data from neutron scattering experiments at energies up to 14 MeV is also provided.
