AbstractThis article presents the main problems associated with cereal harvesting in sloping areas. The presented innovative aerodynamic system supporting the separating unit of combine harvester can be one of the ways to counteract the negative effects of harvesting machines work on slopes. The Monte Carlo numerical method, presented in this article, was applied in the optimization of an aerodynamic sieve separation process on an inclined terrain. The given variables are the transverse slope of separator α (of the sieve), longitudinal slope β and the output of the main and side fans. The Monte Carlo method makes it possible to determine an optimized set of parameters (α = 10°, β = 2.8°, δ = 9°), the output of the main fan (0.67 m3 s−1) and the output of the side fan (1.86 m3 s−1), allowing to obtain the best indicator values of 2.1% grain loss and 97.5% grain purity.

Insight Into

The game of baseball and its internal cryptic communication system has always been vulnerable to sign stealing. By systematically studying the signals of an opponent so as to decrypt and intercept opponent communications, one can garner valuable insight into future events and strategies. Such “theft of signals” can lead teams to frequently change their sign indicator, should they suspect it has been compromised. The current paper presents a theoretical process of “hot” sign indicator obfuscation whereby the pitcher and catcher use unique hot indicator values that are generated after each pitch via an algorithm derived from randomly changing situational and/or scoreboard data.

The Devil

When using indicator values to measure change over an interval of time, the general understanding of the factor being analysed may have been modified during the period under review. Altered definitions of ‘urban’, or ‘poverty’, provide common instances of this phenomenon. This article outlines a similar situation with respect to the ‘access to sanitation’ indicator as it features in the Development Bank of Southern Africa’s series of Development Reports. These publications are often referred to as a ready source of useful information. It is shown how an altered understanding of what constituted ‘sanitation’ in South Africa came to influence the relevant indicator values. This change, if not taken into account, could result in planning calculations yielding invalid conclusions. The article deals with the casual use of ready-to-hand indicators by non- specialist practitioners, and about how easy it is to be misled on occasion.

Macrophyte Index

One of the important tools to evaluate the ecological quality of surface water is the Macrophytes indices based on the bioindication capacity of aquatic plants. In Mediterranean rivers (France, Spain, and Portugal), the development of some macrophytes indices like l’Indice Biologique Macrophytes Rivières (IBMR), the biological metric score (BMS), as well as the Fluvial Macrophyte Index (IMF) are founded on the determination of the indicator values of the floristic reference lists. The aim of this study was to test the impact of the eco-Mediterranean differences (from one country to another) on the indicator taxa by comparing the indicator values of the Euro‐ Mediterranean macrophyte indices. With this in mind, we explore the possibility of the introduction of the Euro‐Mediterranean macrophytes-based indices in Morocco (i.e. the hydrological basin of Sebou (HBS)) as a part of a preliminary attempt to develop the first Afro-Mediterranean macrophyte index. We confirm that the ecological amplitude and species optima vary between Mediterranean ecoregions, and indicator taxa differ between countries: There are medium to small correlations between Mediterranean indices: IBMR/BMS (p = 0.000, R2 = 0.57), IMF/BMS (p = 0.000, R2 = 0.34), and IBMR/IMF (p = 0.000, R2 = 0.30). Five species exhibit major differences in indicator values: Zannichelliapalustris and Potamogetonpectinatus have more eutrophic indicator values in France (IBMR) than in Spain (IMF). Potamogetonnodosus, Amblystegiumriparium and Lycopuseuropaeus have broader ecological amplitudes in Portugal (BMS) than in France (IBMR) and in Spain (IMF), where it is restricted to eutrophic conditions. Furthermore, the three indicator systems include different indicator-taxon numbers. The comparison of the HBS elaborated list with the Euro‐Mediterranean indices revealed the low level of common taxa approximately 6.76% of all indicator species used in the French index (IBMR), 10.48% in the Portuguese index (IMF) and 12.38% in the Spanish index (BMS). These results show the inadequacy of the trophic indices approach with the HBS conditions and thus the need for the development of an index based on biotic indices approach.

In this study, I investigate the linkage between trends in key economic indicators (inflation, unemployment, and growth in gross domestic product) and government survival in 16 postwar European parliamentary democracies. The partial likelihood method, which allows for variation in indicator values over the lifetimes of individual governments, constitutes the basic analytic tool. The findings reveal overall causal roles for both inflation and unemployment, as well as important differences in these roles between socialist and bourgeois governments and between pre-oil crisis and post-oil crisis eras. Most significant, the introduction of these indicators to the analysis helps to resolve the debate between two rival explanations of governmental stability, the bargaining complexity hypothesis and the ideological diversity hypothesis, in favor of the latter.
