Development Gap

The aim of the paper was to estimate the structural development gap in Polish agriculture at the regional level (provinces) and to assess the unification process of economic structure of farms. The economic structure of farms was determined on the basis of the value of Standard Output (SO). The research was conducted based on EUROSTAT data for the period 2005-2013. In order to estimate the structural development gap in agriculture the procedure proposed by Karol Kukuła was used. This procedure is based on the regional structural analysis methods and requires the indication of the exemplar structure - the standard province). The standard province was identified with the use of Hellwig synthetic measure. It was found that the biggest structural development gap of farms was observed in the southern-east region of Poland. At the same time, in provinces from this region of Poland the structural development gap compared to wielkopolskie province served as a standard province increased in the years 2005-2013.

Abstract This paper presents the results of the analysis of the porous structure of biochars produced from biomass, namely eucalyptus, wood chips, pruning waste and rice husk. The structural analysis was carried out using the BET, the t-plot, the NLDFT and the LBET methods, which yielded not only complementary information on the adsorptive properties of obtained biochars from these materials, but also information on the usefulness of the structural analysis methods in question for the research into an effect of the technology of carbonaceous adsorbent preparation.

Development of probabilistic structural analysis methods for hot engine structures is a major activity at Lewis Research Center. It consists of three program elements: (1) composite load spectra methodology, (2) probabilistic structural analysis methodology, and (3) probabilistic structural analysis application. Recent progress includes: (1) quantification of the effects of uncertainties for several variables on High Pressure Fuel Turbopump (HPFT) turbine blade temperature, pressure, and torque of the Space Shuttle Main Engine (SSME), (2) the evaluation of the cumulative distribution function for various structural response variables based on assumed uncertainties in primitive structural variables, and (3) evaluation of the failure probability. Collectively, the results demonstrate that the structural durability of hot engine structural components can be effectively evaluated in a formal probabilistic/reliability framework.

An example of the application of probabilistic structural analysis to welds is presented below. . The same methodology can be used for probabilistic structural analysis of parent metals in tank structures and other structural components such as supports. The methodology is based on a stress vs. strength model. The results may be used for a comparative analysis of candidate weld process improvements. The model can be incorporated into a probabilistic risk assessment which includes the undesirable impacts of weld failure.
