Upotreba beskontakne metode za ocjenu kvalitete površine drva nakon visokobrzinskog blanjanja

This paper presents the method of surface quality evaluation at high-speed milling of wood. The effects of specific parameters of machining on the surface quality are described and results are presented of experiments carried out on selected tree species, where the effects of specific parameters on the surface quality were noted. The surface quality is evaluated by a non-contact method using a confocal sensor (CLA), which processes the results of the roughness measurement, Talysurf CLI 1000. It can be concluded that this method could actually be used for the evaluation of the surface quality.U radu se analizira metoda za ocjenu kvalitete površine drva nakon visokobrzinskog blanjanja.

Sledování prevalence výskytu dekubitů u 65letých a starších mužů a žen ve vztahu ke kategoriím bmi hospitalizovaných na interním oddělení

Dekubity jsou stále celosvětovým onemocněním, jejichž riziko vzniku je zvýšeno jak podváhou, tak obezitou, ovšem obezita je u populace oproti podvýživě častější a počet lidí s nadváhou či obezitou stále roste. Cílem výzkumu bylo zjistit vztah mezi výskytem dekubitů a jednotlivými kategoriemi BMI u 65letých a starších pacientů (n=122, 51,6 % žen, 48,4 % mužů) hospitalizovaných na interním oddělení. Data byla získána ze zdravotnické dokumentace a z nemocničního informačního systému nežádoucích událostí a z vlastního antropometrického měření. Do výzkumného vzorku byli zařazeni pacienti, kteří splňovali vstupní kritéria (věk nad 65 let, vzniklý dekubitus, hospitalizace na interním oddělení). Ze zjištěných výsledků vyplývá, že vyšší četnost dekubitů byla zaznamenána u pacientů s nadváhou (34,6 %). Nejčastější lokalizací dekubitu jak u mužů, tak u žen byla oblast kosti křížové (66,91 %). Z výsledků vyplývá potřeba více vyspecifikovat rizikové faktory v souvislosti s antropometrickými ukazateli pro snížení výskytu dekubitů, popř. zamezení zhoršování jednotlivých stupňů proleženin

Habitat preferences and functional traits drive longevity in Himalayan high-mountain plants

Plant lifespan has important evolutionary, physiological, and ecological implications related to population persistence, community stability, and resilience to ongoing environmental change impacts. Although biologists have long been puzzled over the extraordinary variation in plant lifespan and its causes, our understanding of interspecific variability in plant lifespan and the key internal and external factors influencing longevity remains limited. Here, we demonstrate the concurrent impacts of environmental, morphological, physiological, and anatomical constraints on interspecific variation in longevity among > 300 vascular dicot plant species naturally occurring at an elevation gradient (2800–6150 m) in the western Himalayas. First, we show that plant longevity (ranging from 1 to 100 years) is largely related to species' habitat preferences. Ecologically stressful habitats such as alpine and subnival host long-lived species, while productive ruderal and wetland habitats contain a higher proportion of shorter-lived species. Second, longevity is influenced by growth form with monocarpic forbs having the shortest lifespan and woody shrubs having the highest. Small-statured cushion plants with compact canopies and deep roots, most found on cold and infertile alpine and subnival soils, had a higher chance of achieving longevity. Third, plant traits reflecting plant adaptations to stress and disturbance affect interspecific differences in plant longevity. We show that longevity and growth are negatively correlated. Slow-growing species are those that have a higher chance of reaching a high age. Finally, higher longevity was associated with high leaf carbon and phosphorus, low root phosphorus and nitrogen, and with large bark-xylem ratio. Our findings suggest that plant longevity in high elevation is intricately determined by a combination of habitat preferences and growth form, as well as the plant growth rate and physiological processes.publishedVersio

Polypyrrole nanotubes and their carbonized analogs: Synthesis, characterization, gas sensing properties

Polypyrrole (PPy) in globular form and as nanotubes were prepared by the oxidation of pyrrole with iron(III) chloride in the absence and presence of methyl orange, respectively. They were subsequently converted to nitrogen-containing carbons at 650 °C in an inert atmosphere. The course of carbonization was followed by thermogravimetric analysis and the accompanying changes in molecular structure by Fourier Transform Infrared and Raman spectroscopies. Both the original and carbonized materials have been tested in sensing of polar and non-polar organic vapors. The resistivity of sensing element using globular PPy was too high and only nanotubular PPy could be used. The sensitivity of the PPy nanotubes to ethanol vapors was nearly on the same level as that of their carbonized analogs (i.e., ~18% and 24%, respectively). Surprisingly, there was a high sensitivity of PPy nanotubes to the n-heptane vapors (~110%), while that of their carbonized analog remained at ~20%. The recovery process was significantly faster for carbonized PPy nanotubes (in order of seconds) compared with 10 s of seconds for original nanotubes, respectively, due to higher specific surface area after carbonization. © 2016 by the authors; licensee MDPI, Basel, Switzerland

Global maps of soil temperature

Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic variables at a 1-km2 resolution for 0–5 and 5–15 cm soil depth. These maps were created by calculating the difference (i.e. offset) between in situ soil temperature measurements, based on time series from over 1200 1-km2 pixels (summarized from 8519 unique temperature sensors) across all the world\u27s major terrestrial biomes, and coarse-grained air temperature estimates from ERA5-Land (an atmospheric reanalysis by the European Centre for Medium-Range Weather Forecasts). We show that mean annual soil temperature differs markedly from the corresponding gridded air temperature, by up to 10°C (mean = 3.0 ± 2.1°C), with substantial variation across biomes and seasons. Over the year, soils in cold and/or dry biomes are substantially warmer (+3.6 ± 2.3°C) than gridded air temperature, whereas soils in warm and humid environments are on average slightly cooler (−0.7 ± 2.3°C). The observed substantial and biome-specific offsets emphasize that the projected impacts of climate and climate change on near-surface biodiversity and ecosystem functioning are inaccurately assessed when air rather than soil temperature is used, especially in cold environments. The global soil-related bioclimatic variables provided here are an important step forward for any application in ecology and related disciplines. Nevertheless, we highlight the need to fill remaining geographic gaps by collecting more in situ measurements of microclimate conditions to further enhance the spatiotemporal resolution of global soil temperature products for ecological applications
