This study identifies the long lasting impacts of former cultivation on soils, seed banks and above-ground vegetation of limestone grasslands. We compared the resilience of three crop fields cultivated in the 19th century and abandoned (Abandoned Fields) with three grasslands which have never been cultivated (Old Grasslands). Grasslands were located in the Nature reserve of Grand-Pierre and Vitain valleys in France. Sites were identified using historical sources. Chemical and physical soil properties, above-ground vegetation and soil seed bank (0–10 cm and 10–20 cm) were studied. Data were analysed using a multivariate and univariate analyses to detect the effects/impacts of ancient cultivation. Our results clearly show that soil properties (e.g., calcium, carbonate, clay contents), above-ground vegetation (species diversity, moss and lichen cover) and seed bank (floristic composition, species-richness and diversity) are still impacted more than one century after their abandonment. Species richness of both above ground vegetation and seed bank are higher in old grasslands than in formerly cultivated fields. In the seed bank of the formerly cultivated soils we also found the presence of a very rare arable weed species (Althaea hirsuta) which has not been inventoried for a long time in the above-ground vegetation of the nature reserve. The resilience of formerly cultivated limestone grasslands might be influenced by the present management regime (site effect). Nevertheless, the resilience period of limestone grasslands is very long-more than one century-and return to an initial state might be difficult or impossible to reach.
During the architectural planning of modern, complex, block-structured, large-area located, but still landscape-harmonized health-care buildings, the key is the optimal positioning of the blocks and functions, simultaneously ensuring the most-effective backup-paths for any single transportation route failure in the buildings to speed up the operation, reduce the maintenance costs and especially to improve the satisfaction of the patients. Mathematical statements are to be solved with multiple serious challenges when formulating the positioning problem with resilience to the buildings for any single failure. An innovative graph representation referred as link doubling is presented where Minimal cost multi commodity flow problems could be solved.
Sustainable land use
and rational soil management, including an up-to-date soil moisture control
requires continuous actions. This permanent control may prevent, eliminate or
at least reduce undesirable soil processes and their harmful
economical/ecological/environmental/social consequences; utilizing the unique
soil characteristic, resilience, may satisfy the conditions for the “quality
maintenance” of this “conditionally renewable” natural resource. Control can be
efficient only on the basis of comprehensive risk assessment, impact analysis
and exact prognosis. These have to be the main research priorities! The
successful prevention, elimination or moderation of undesirable soil
degradation processes and extreme moisture regimes can be efficient only in a
well-coordinated multidisciplinary international cooperation in the Carpathian
Basin. The realization of the sustainability concept in the rational land use
and soil management gives reality for a better life: healthy, good quality
food, clean water and pleasant environment.

Eight descriptive sensory textural attributes of whole date fruit were evaluated by twenty trained panel members and correlated with sixteen physicochemical properties. All sensory parameters, except gumminess, significantly correlated (Ps<0.05) with pectin, crude fibre, and moisture content. In addition, sensory hardness, cohesiveness, elasticity, and resilience correlated significantly with length of whole fruit (P<0.05), sensory adhesiveness with glucose content (P<0.05), sensory chewiness with mass of whole fruit (P<0.05), and sensory gumminess with fructose, glucose, and total sugar content (P<0.10). Sweetness, however, correlated only with moisture content (P<0.05). CA and the biplot (i.e. including all products, their sensory texture and physicochemical attributes) generated through PCA recognized three groups of dates as hard-chewy, soft-(medium-chewy), and soft-(non-adhesive).
Different long-term experiments were carried on chernozem (Debrecen) and loamy (Hajdúböszörmény) soils. They included the most important agrotechnical, biological (hybrid) and agroecological (crop year, soil) factors in maize production. This paper evaluated the results of polyfactorial long-term experiments. For the maize the most favourable crop rotation was winter wheat (in a tri-culture) with an N 60–120, P2O5 60–70, K2O and 90–110 kg ha−1, and a density of 75–90,000 plants ha−1. The different input levels of maize crop management systems can modify an adaptive capacity to ecological conditions and the resilience of agro-ecosystems. The optimalization of agrotechnical elements reduces the harmful climatic effects. The yields of maize varied between 2–11 t ha−1 in extensive and 10–15 t ha−1 in intensive crop management systems, respectively.
Hungarian red clays are the result of soil formation from previous geologic periods. They were spread over areas which were dry during the Tertiary Period and were not covered by sediments. The climate of the Quaternary Period eroded them, so that today they can only be found in areas where they were protected against degradation or where their thickness and resilience could withstand the forces of erosion. Thus, red clays are fossil or relic products of soil formation. Since both their water regime and nutrient supply differ from soils formed in the Holocene, their economic importance is far from negligible; vineyards, forests and arable cultivation can be found on these areas. Their influence may be seen in more extensive territories where they were washed away, settled and became mixed with other soils.
