This paper is intended to show the importance of spatial accounting, the practicality ofmapping and illustration. To this end, biomass potential that can be grown on arable lands and the resulting indicators were studied on the example of the Tabi járás (Tabi district) of Hungary. The processed data was projected onto maps for mapping the absolute potential, but also specific indicators such as values per hectare or per capita. The results are plotted in equal intervals and along with natural fractures classification of the data. The results thus obtained emphasize the heterogeneity caused by spatial unevenness. Taking such information into account can improve the efficiency of state interventions, investments, developments and the decentralization of other decisions.

Background: Large-scale and population-based studies of heart failure (HF) incidence and prevalence are scarce in China. The study sought to estimate the prevalence, incidence, and cost of HF in China. Methods: We conducted a population-based study using records of 50.0 million individuals ≥25 years old from the national urban employee basic medical insurance from 6 provinces in China in 2017. Incident cases were individuals with a diagnosis of HF (International Classification of Diseases code, and text of diagnosis) in 2017 with a 4-year disease-free period (2013–2016). We calculated standardized rates by applying age standardization to the 2010 Chinese census population. Results: The age-standardized prevalence and incidence were 1.10% (1.10% among men and women) and 275 per 100 000 person-years (287 among men and 261 among women), respectively, accounting for 12.1 million patients with HF and 3.0 million patients with incident HF ≥25 years old. Both prevalence and incidence increased with increasing age (0.57%, 3.86%, and 7.55% for prevalence and 158, 892, and 1655 per 100 000 person-years for incidence among persons who were 25–64, 65–79, and ≥80 years of age, respectively). The inpatient mean cost per-capita was $4406.8 and the proportion with ≥3 hospitalizations among those hospitalized was 40.5%. The outpatient mean cost per-capita was $892.3. Conclusions: HF has placed a considerable burden on health systems in China, and strategies aimed at the prevention and treatment of HF are needed.

Herbaceous Perennial

Erodium tataricum is a herbaceous perennial multi-headed tap-root (caudex) plant. Hemicryptophyte. Endemic. The ontogenetic structure was studied in the shrub-herb-grass petrophytic steppe. Individuals of the species have four periods and ten ontogenetic states. It was revealed that the population is normal with an incomplete spectrum. In accordance with the classification of A. A. Uranova and O. V. Smirnova the population is definitive. According to the criterion of the absolute maximum, the population is young. The ontogenetic spectrum of the population is left-sided. A specific ontogenetic spectrum corresponds to a characteristic ontogenetic spectrum, i.e. biology of the species. According to the ontogenetic spectrum, the development of the population is characterized as sustainable. The peculiarity of Erodium tataricum is that on all aerial parts of the plant there is abundant pubescence, but in the old generative ontogenetic state, pubescence on the leaves decreases. Reproduction of the species is carried out by seed. In the subsenile ontogenetic state, senile particulation is possible.

Peak Phase

The Nigerian agricultural export sector has been through three different development phases: transition, peak, and de-agriculturalisation. Blending simple international trade theory with actual facts, this study supports the notion that production during the transition phase enjoyed a classical "vent for surplus" type of growth, involving increased utilisation of available factor inputs, which in turn produced increased per capita income. Coupled with the classical factors were several technological packages introduced to farmers in later years. These led to the attainment of output peaks mainly in the 1950s and 1960s. Finally. the study argues that the foundation for de-agriculturalisation was already laid during the peak phase when farmers were taxed heavily, and several agricultural projects were biased against them.

The absolute luminosity of most Be stars can be determined by using Balmer line narrow band photometry with an accuracy of about 0.4 mag. The few cases in which this method fails can be detected.

Abstract The aim of this paper is to analyze the convergence process among former Socialist countries, the Central and Eastern European (CEE), Western Balkan and Eastern Partnership countries. The relationships between the selected macroeconomic variables and per capita GDP growth rate are econometrically tested to support this research. The analyzed period is 2004-2016, with two sub-periods; 2004-2008 and 2009-2013. The subdivision is made to test if the recent financial crisis affected the absolute and conditional convergence process. The empirical findings support the economic convergence hypothesis. The results show that the recent financial crisis negatively affected only the absolute convergence process. The negative effects of the crisis on conditional convergence are not identified. The poorer countries in the analyzed group should do more to attract investment, as gross fixed capital formation has a clear positive impact on per capita growth in the examined sample of countries.
