Insurance Market
Opis:
The insurance sector in Poland has been developing in certain conditions of macro-economic environment. The process in which the phenomena in the insurance market takes place is determined by the speed of development of the whole economy. The dynamics of the development may be seen in the size of GDP, in the size of foreign trade and in the level of foreign investments. The macroeconomic indicators confirm the continuing economic growth. This affects the development of the market in a favourable way because it means that there is a large demand for insurance products. The increasing demand is a strong stimulus of the further market development. Good forecasts of the economic development encourage foreign investors to deposit capital in Poland. The insurance sector is also an attractive place for foreign investments. The conditions of activity of the insurance market have been determined by law regulations that are based on the directives of the European Union. Although the level of development of the Polish insurance market is still lower than in many countries of the European Union the currently perceived tendencies lead to a decrease of the existing disproportions.

Opis:
The last financial crisis affected the SMEs sector in different countries at different levels and strength. SMEs represent the backbone of the economy of every country. Therefore, they need bankruptcy prediction models easily adaptable to their characteristics. In our analysis we verified hypothesis: including information about macroeconomic conditions significantly increases the effectiveness of the bankruptcy model. The data set used in our research contained information about 1,138 SMEs. All information was taken from the financial statements covering the period 2002-2010. The sample included enterprises from sectors: industry, trade and services. Selected financial ratios were used to build the model and the macroeconomic variables were added: GDP, inflation, and the unemployment rate. Logistic regression as the research method was applied. In our study we showed that the incorporation of the macro variables improved the prediction of the SMEs bankruptcy risk.

Opis:
Energy efficiency (EE) of wireless telecommunications has become a new challenge for the research community, governments and industries in order to reduce CO2 emission and operational costs. EE of base stations (BSs) in cellular networks is a growing concern for cellular operators to not only maintain profitability, but also to reduce the overall negative impact to the environment and economic issues for wireless network operators. In this paper, a framework focuses on the Area Energy Efficiency (AEE) evaluation of LTE BSs is presented. The parameters affect on the AEE and the coverage area of LTE BS in different scenarios are investigated. AEE analysis has been done using a few key performance indicators including transmit power, bandwidth, load factor with the assumption of different scenarios (urban, suburban and rural). The simulation results show that the LTE BSs have better AEE in an urban environment for cell radius less than 750 m compare with the suburban and rural environments. Furthermore, it is obvious that there is a strong influence of traffic load, BW and transmission power on AEE of LTE network. On the other hand, AEE increases significantly as the BW size increases. Finally, it has been shown that the AEE of LTE macro BS decreases with increasing the percentage of traffic load for all scenarios.

Opis:
The research was carried out in the morainic areas and in river valleys in NE Poland, where seven sites located in the macroregion of Masurian Lakeland were selected. Thirteen soil profiles representing the following organic soils were studied: earth-covered murshic soils (OMnm), murshic peat soils (OTmu), hemic murshic soils (OMhe) and sapric murshic soils (OMsa). The aim of the research was to investigate the content of selected macro- and microelements in surface formations of organic soils and to determine the influence of sedimentation processes on their spatial distribution. In terms of quantity, the analyzed macro- and microelements can be arranged as follows: Ca > Al > Fe > K > Mg > Na > P > Mn > Zn > Pb > Cr > Ni > Cu > Co. Organic soils situated in the depressions had various degrees of silting with mineral sediments from the nearby areas. Along with erosive waters, deluvial material rich in minerals was flowing along the morainic slopes. Therefore, mineral-organic formations (AO) located in the ecotone zone between mineral and organic soils had the highest content of total Mg – 4.85 g kg-1, K – 5.94 g kg-1, Al – 24.87 g kg-1, Fe – 17.77 g kg-1, Zn – 0.066 g kg-1, Cr – 0.046 g kg-1, Ni – 0.025 g kg-1, Pb – 0.060 g kg-1. The highest content of total calcium, manganese, iron, copper and cobalt was found in mineral-organic formations (AO) and strongly silted murshes (Mtsz). The contents of calcium and sodium were significantly positively and the contents of other macro- and microelements were significantly negatively correlated with the amount of organic matter, organic carbon and total nitrogen.

An article entitled Words Mean. Words Look. Words Sell (Themselves) focuses on three issues: dominance of the use of English loanwords over attempts to create their Polish equivalents (as a result of which a product, a process, an event, or an artefact promoted by the English-speaking culture is adopted together with its name), a trend whereby words (and titles composed of words) become images (through a choice of font, a non-standard use of lowercase and uppercase letters, or an inclusion of non-letter characters, e.g. parentheses), and ascribing to words present in micro-acts a promotional function, advertising the entire product – a text. The trends discussed in the article are not new, but it is their intensity level that is new.

Opis:
Various apple rootstock genotypes may affect fruit tree nutrition. The plant nutritional status has a significant impact on the growth and yield of apple trees. The experiment was conducted in 2007-2015, at the Experimental Station in Samotwór near Wrocław, south-western Poland. During the nine-year study, the impact of different rootstocks (M.26, B.7-35, B.396, ARM 18, M.9, B.491, P 16, B.146 and PB-4) on the nutritional status, growth and yield of ‘Mutsu’ apple trees was investigated. Samples of leaves were collected for the analysis of macro– and microelements in the second half of July in 2009-2011. The study showed an ambiguous influence of rootstock on leaf macro-and microelement composition. This effect differed depending on a year. The results of the average content of the analysed components showed no effect of a rootstock on P, Mg, Mn and Zn concentrations in the leaves. M.26 rootstock resulted in the lower copper level (a significant difference when compared to B.7-35, M.9, B.146 and B.491). Trees on B.491, M.26 and B.7-35 rootstocks were worse stocked in boron than apple trees on ARM-18, M.9 and B.396. In comparison with stronger growing rootstocks, trees on PB-4 were characterised by the low content of calcium. Trees on B.7-35 rootstock grew the most, while the ones grafted on PB-4 showed the weakest growth and had the smallest fruits. The highest number of root suckers was observed for trees grafted on B.7-35 and ARM 18. Until the ninth year after planting, the largest yield was obtained from trees on B.396. In the present study, this rootstock proved to be the best for the ‘Mutsu’ cultivar

The aim of the paper is to compare reactions of two stock markets, the German and the French, to releases of macroeconomic fundamentals emanating from Germany and the U.S. We examine the reaction of intraday returns and volatility of the CAC40 and the DAX indices to macroeconomic surprises. We find that both American and German macroeconomic releases cause an immediate response in returns and volatility of the German and the French stock market sampled at a five-minute frequency. The reaction to the American macroeconomic surprises is stronger than to the German ones.

Opis:
Additional sound sources are used as actuators in the vast majority of active noise reduction systems. One of the possible opportunities to extend the field of applications of active noise reduction systems is using active structures of variable sound insulation. The paper presents an analysis of ways of reducing noise with a structure of variable sound insulation consisting of a metal plate, active elements (Macro Fiber Composite), and a control system. The paper presents results of acoustic radiation simulations and measurements of sound intensity generated by the structure under the influence of stimulation by an acoustic wave. Simulations of mechanical vibrations and acoustic radiation for the plate were performed with the finite element method and ANSYS software. Simulation results made it possible to select locations for gluing the active elements and sensors. Analyses of the sound pressure level in the space to which the plate is radiating made it possible to determine dominant frequencies in the characteristics and, as a result, indicate vibration modes that can be reduced. Sound intensity measurements were performed with a three-way probe of USP mini Microflown. Results of simulations and measurements show that it is possible to achieve an improvement of the insulating power of a metal plate by approx. 10 dB.

Opis:
Circular economy (CE) is an interesting approach by many countries to address global environmental problems while gaining economic benefits. The implementation of CE is expected to minimize the use of resources and materials, thus contributing to sustainable development. Much literature has discussed CE assessment indicators and their evaluation, however to date, no single indicator has been proposed that can comprehensively measure the macro level of CE implementation. This study aims to develop a CE index to measure CE implementation at macro levels. In addition, it provides an overview of the impact of CE implementation on the financial, social, and environmental aspects of the economy. To this end, first, an in-depth literature review and descriptive analysis is conducted to identify existing global CE indicators and classify them into financial, social, and environmental categories based on available primary and secondary data. Then, the CE index is constructed using a mathematical equation by considering the CE framework, a single indicator of each aspect as a variable, and the variable’s weighting. Finally, the CE index is applied to evaluate the level of CE implementation of CE in Indonesia at macro level. This index is expected to be a valuable tool for measuring CE implementation and therefore improving CE performance.

Soil amendment usage can substantially modify soil structural and hydraulic properties, with the aim of improving its water, air and nutrition management along with crop growth. The purpose of the present study was to investigate the physical changes in soil through different plant growing stages caused by biochar addition to silt loam soil. This research focused on changes in structural stability, and macro- and microaggregate stability. The soils were amended with different amounts of biochar (control with 0, BC0.5 with 0.5%, BC2.5 with 2.5%, and BC5.0 with 5.0% biochar, by weight). Capsicum annuum L. were planted at a two-four leaf stage. Soil samples were taken at 6, 10 and 12 weeks after planting. The results showed increasing macroaggregate stability values with increasing biochar addition; however, higher values were also detectable in control treatments over time. Increased microaggregate stability values were observed during the plant maturing phase and the decrease, which occurred during fruit development was more pronounced. The largest microaggregate stability value was observed in the case of BC2.5 among all treatments, which corresponded better to plant growth rather than to the amount of added biochar. It was also found that the laser diffraction method is a suitable alternative technique to the sieve-pipette method for analysing biochar and biochar-amended soil particle size distribution and structure.

Opis:
Magnetorheological elastomers (MREs) are the materials with rheological properties which can be rapidly and reversibly changed in a continuous way by the applied magnetic field. They are the solid analogues of magnetorheological fluids (MRFs) consisting of magnetically permeable particles (such as iron) added to a viscoelastic polymeric material prior to crosslinking. In the paper different approaches to numerical modelling of the magnetorheological elastomers (MREs) structures are presented. The methods of the MRE micro- and macrostructural FE simulations are taken into consideration. The first approach is connected with the microstructural behaviour of the iron particles situated in the pure elastomer and subjected to the mechanical or magnetic load. The second approach is related to global material properties consideration and macrostructural behaviour modelling. The paper shows that there are many ways of such new materials structure behaviour modelling. All the FE analyses always need to be verified with the experiments as well as for macro- and micro scale material reactions, properties and phenomena describing.
