Public debt sustainability in Serbia before and during the global financial crisis

We have analyzed the behaviour of primary fiscal balance and public debt in Serbia before and in the aftermath of the global financial crisis. The results of our analysis are: i) public debt to GDP ratioexhibits (near) unit root behaviour with an overall upward time trend; ii) the response of primary fiscal balance to public debt has been insufficient to mean revert the upward trend in government debt; iii) the efforts of the Serbian government to repay the debt principal after the fiscal rule breach have not been persistent, providing empirical support to the fiscal fatigue hypothesis; iv) the government budget constraint has deteriorated since the beginning of the global financial crisis; v) the response of primary fiscal balance to public debt from the onset of the global financial crisis has dropped more severely in comparison to other European economies

Fiscal Reaction to Interest Payments-the Case of Serbia

We focus on the response of primary fiscal balance to interest payments and borrowing costs on Serbian public debt before, during and in the aftermath of the global financial crisis. Our analysis reveals: i) policy makers financed up to 50% of each percentage point increase in interest payments to GDP ratio with new public debt issuance; ii) the government has responded to rising interest payments and borrowing costs by reducing primary fiscal balance from the onset of the global financial crisis; iii) the response of primary fiscal balance to interest payments mimics the response of primary fiscal balance to the costs of borrowing; iv) fiscal austerity measures adopted after the breach of fiscal rule for public debt have been insufficient to stabilize fiscal policy stance in Serbia

INFLUENCE OF THE NUMBER OF PREVIOUS CAESAREAN SECTIONS ON LOWER UTERINE SEGMENT STATE

Determining the lower uterine segment (LUS) state before vaginal delivery and after Caesarean section, including pregnant women with more than one Caesarean section, may be an important step towards prevention from still high maternal and neonatal morbidity and mortality that follow uterine rupture. In pregnant women with one or more previous Caesarean sections, ultrasonic measuring of thickness and estimating the LUS integrity can objectively show the state of uterine scars. The aim of this study was to determine the influence of several previous Caesarean sections on the LUS state in term pregnant women. The prospective study included 62 pregnant women with one or more previous Caesarean sections – the examined group, and 50 pregnant women without Caesarean section – the control group, that after the 37th week of pregnancy had undergone the transvaginal ultrasonic measuring of the thickness of the LUS muscular tissue. In 57 pregnant women from the examined group delivered with another Caesarean section, we estimated, intraoperatively, the LUS integrity in the scar area. On the same occasion, in the scar area, the presence of defect – partial or complete was detected. The research pointed out that the average LUS thickness in the examined group – 1.92±0.95mm was statistically significantly lower compared to the control group – 2.68±0.97mm (p<0.001). The average LUS thickness in 52 examined women with one Caesarean section was 1.92±0.97mm, and in 9 women with two Caesarean sections the average thickness was lower – 1.78±0.82mm, which does not represent a statistically significant difference (p=0.85). In one pregnant woman with three Caesarean sections, the LUS thickness was 3.30mm. We registered the total of 13 pregnant women with a defect in the Caesarean section scar area (12 partial and 1 complete defects), in 12 women after one Caesarean section and in 1 woman after two Caesarean sections. The research results show that women with previous Caesarean section have significantly thinner LUS, compared to the group of pregnant women without scars. With the increasing number of previous Caesarean sections, the LUS thickness decreases, but the difference is not statistically significant. Intraoperatively, the presence of certain LUS classes compared to the number of previous Caesarean sections is not significantly different. Furthermore, the increase in the number of Caesarean sections does not involve a statistically significant increase in the frequency of Caesarean section scar defects, which is in accordance with other authors’ results

UTJECAJ SKLADIŠTENJA NA VIGOR I SADRŽAJ ULJA U SJEMENU KUKURUZA, SOJE I SUNCOKRETA

The study aimed to examine the changes in seed vigor and oil content in different genotypes of maize, soybean and sunflower over three years (2002-2005) in two type storage conditions differed in terms of air temperature and humidity: 25°C/75% and 12°C/60%, respectively. Affected by storage longevity, on an average, seed vigor decreased by 13.5% in maize and by 26.5% in both soybean and sunflower, respectively. Seed oil content decreased by 0.58% in maize, 1.68% in soybean and 8.04% in sunflower. Differences in seed vigor and oil content affected by storage longevity were significant among tested crops and genotypes into crop. Storage longevity was negatively associated with seed vigor and oil content. At storage conditions by 12°C/60%, decline of seed vigor was less by 7% (maize), by 11% (sunflower, soybean) and decreasing of seed oil content was less for 0.25% (maize), 0.53% (soybean) and 1.75% (sunflower) than in storage conditions by 25°C/75%. In summary, the lowest seed quality losses were in maize, followed by soybean and the highest ones in sunflower. Decreasing seed quality losses is possible with providing suitable storage conditions, particularly for soybean and sunflower.Istraživanjem je utvrđen utjecaj uvjeta skladištenja dorađenog nezaprašenog sjemena hibrida kukuruza i suncokreta te sorata soje na vigor i sadržaj ulja nakon skladištenja od 36 mjeseci (2002.-2005.) u dva tipa skladišta različite temperature i vlage zraka (S1: 25°C/75% i S2 12°C/60%). Nakon skaldištenja, vigor sjemena je umanjen za 13,5% kod kukuruza, 26,5% kod soje i 27,1% kod suncokreta. Sadržaj ulja u zrnu je umanjen za 0,58% kod kukuruza, 1,68% kod soje i za 8,04% kod suncokreta. Duljinom skladištenja umanjen je vigor i sadržaj ulja. U uvjetima skladišta S1 je manje umanjenje vigora za 7% (kukuruz), 11% (suncokret, soja), kao i manje umanjenje sadržaja ulja za 0,25% (kukuruz), 0,53% (soja) i 1.75% (suncokret) u odnosu na uvjete skladištenja u skladištu S2. Kakvoća sjemena je tijekom skladištenja ovisna o vrsti kultivara, genotipu i uvjetima skladištenja

RESPONSES OF THE IONOSPHERIC D-REGION TO PERIODIC AND TRANSIENT VARIATIONS OF THE IONIZING SOLAR Lyα RADIATION

Solar radiation has the most important role in periodical variation of terrestrial atmospheric properties. Under unperturbed ionospheric conditions, the solar Lyα line has a dominant influence on ionization processes in the lowest ionospheric layer, the so called D-region. In this paper, we present periodical and transient variations in influences of the Lyα radiation on this ionospheric layer. In the case of periodical lower ionospheric changes we consider diurnal, seasonal and solar cycle variations and show analysis of acoustic and gravity waves induced by solar terminator. Influences of solar flares and eclipses on this atmospheric layer are analyzed as examples of sudden ionospheric disturbances. For decades, Very Low Frequency radio signals (3 – 30 kHz) are successfully used as a tool for monitoring of changes in the lower ionosphere, based on radio wave propagation through Earth-ionosphere waveguide along given trajectories and registration of their physical parameters (amplitude and phase delay). For the analysis conducted in this paper, we used records of the VLF DHO signal, emitted on 23.4 kHz frequency from transmitter in Germany and received in Serbia

Relishes: The new pickled vegetables

There have been an increasing interest of consumers for a ide variety of pickled vegetable products worldwide. Regarding the regional vegetable supplies and relatively poor assortment of ready-to-use products, the need to broaden the offer of domestic pickled vegetables at the market came out. In this work recipes for different vegetables, spices and condiments were developed. The best graded samples were analyzed for their main chemical composition (dry matter, proteins, oils and fats, total acidity, total sugars, sucrose, starch, cellulose, pH) and energy- values
