Multi-speed Europe? An Analysis of the Real Convergence within the European Union
Reaching an appropriate level of economic, social and territorial convergence has been a strategic goal for European policy and decision-makers. The author’s first assumption is that although in the early stages of the regional project, the Member States had similar growth and development levels, with the advancement of the integration process, the development asymmetries increased. In this paper, the authors stress the fact that the European decision-makers and researchers have become more and more interested to study if the Member States of the European Union meet the criteria for certain types of convergence: nominal, real, legal, structural and institutional. This paper brings to the fore-front the process of real convergence, trying to respond to the question if the Member States are catching-up, or are diverging. Moreover, taking into consideration the enlargement of the European Union with the countries from Central and Eastern Europe, we have studied the main trends within this group of countries. In this respect, we have calculated the σ and β convergence for three geographical clusters of countries: Central Eastern, North Western and Southern Europe. The results obtained show that the economies of the New Member States increased faster than those of the North-Western countries, experiencing a significant speed of convergence. In contrast, the North-Western countries recorded a negative pace in terms of convergence and significant discrepancies between them. In conclusion, the paper shows that the desiderate of real convergence becomes more and more difficult to achieve as while the Central and Eastern Europe states make important steps in reducing the disparities between them and also catching up with the European Union’s average, the Southern Europe countries are diverging.

AGROCHEMICAL CHARACTERIZATION OF SOILS FROM OLT COUNTY
In order to characterize from the agrochemical point of view the soils from Olt County, there were considered agrochemical studies conducted in the county by OSPA Olt in the period 2008-2012, on the entire surface of the county at all land use categories. In the period subject to the agrochemical study, soil samples were collected from agrochemicals plots with different surfaces according to usage and were analyzed: the pH, humus content, nitrogen, phosphorus and potassium. After analysis it was found that:- Soil humus content is low and very low to cca.48% of agricultural land, requiring large expenses with additional fertilization;-The presence of large areas of acidic soils (about 45% of agricultural land) limits yields per unit of area;- Low and very low-supply in mobile phosphorus (cca.57% of agricultural land) limiting production in all cultures and affects crop quality

Identifying jumps in financial assets: A comparison between nonparametric jump tests
We perform a comprehensive Monte Carlo comparison between nine alternative procedures available in the literature to detect jumps in financial assets using high-frequency data. We evaluate size and power properties of the procedures under alternative sampling frequencies, persistence in volatility, jump size and intensity, and degree of contamination with microstructure noise. The overall best performance is shown by the Andersen, Bollerslev, and Dobrev (2007) and Lee and Mykland (2008) intraday procedures (ABD-LM), provided the price process is not very volatile. We propose two extensions to the existing battery of tests. The first regards the finite sample improvements based on simulated critical values for the ABD-LM procedure. The second regards a procedure that combines frequencies and tests able to reduce the number of spurious jumps. Finally, we report an empirical analysis using real high frequency data on five stocks listed in the New York Stock Exchange
Efficiency of foliar fertilization on wheat production in conventional and conservation agriculture
The paper presents the leaves fertilization influence upon wheat yield in two experiments carried out in conventional
agriculture and conservative systems. The experimental fields comprised 6 leaves fertilizers variants and a control and
were laid out at SCDA Teleorman on a Haplic Phaeozem. Two treatments were applied with 1.25% leaves fertilizer on a
N90P40K0 agrochemical background proceeded from a complex 20-20-0 fertilizer, in the autumn, before sowing, and 50
kg N/ha Nitrocalcar, applied in the spring. Leaves fertilization, applied in the conservative system experiment, didn’t
bring forth a significant yield increase as compared to the control. Significant and distinctly significant increases of the
wheat yield were obtained in the conventional agriculture system, from 5,795 kg/ha in the control up to 7,373 kg/ha in the
Nutrifert S variant. The average conventional agriculture yield (6,978 kg/ha) was higher than the conservative agriculture
one (5,457 kg/ha) by 27.8%
Ethanol Administration Produces Divergent Changes in GABAergic Neuroactive Steroid Immunohistochemistry in the Rat Brain
The 5α-reduced pregnane neuroactive steroid (3α,5α)-3-hydroxypregnan-20-one (3α,5α-THP or allopregnanolone) is a potent positive modulator of GABAA receptors capable of modulating neuronal activity. In rats, systemic ethanol administration increases cerebral cortical and hippocampal levels of 3α,5α-THP, but the effects of ethanol on 3α,5α-THP levels in other brain regions are unknown. There is a large body of evidence suggesting that 3α,5α-THP enhances ethanol sensitivity, contributes to some behavioral effects of ethanol, and modulates ethanol reinforcement and motivation to drink. In the present study, we used immunohistochemistry (IHC) to determine ethanol-induced changes in cellular 3α,5α-THP expression in brain regions associated with ethanol actions and responses
