Tsunamis are unpredictable events and catastrophic in their potential for destruction of human lives and economy. The unpredictability of their occurrence poses a challenge to the tsunami community, ...as it is difficult to obtain from the tsunamigenic records estimates of recurrence rates and severity. Accurate and efficient mathematical/computational modeling is thus called upon to provide tsunami forecasts and hazard assessments. Compounding this challenge for warning centres is the physical nature of tsunamis, which can travel at extremely high speeds in the open ocean or be generated close to the shoreline. Thus, tsunami forecasts must be not only accurate but also delivered under severe time constraints. In the immediate aftermath of a tsunamigenic earthquake event, there are uncertainties in the source such as location, rupture geometry, depth, magnitude. Ideally, these uncertainties should be represented in a tsunami warning. However in practice, quantifying the uncertainties in the hazard intensity (
i.e.,
maximum tsunami amplitude) due to the uncertainties in the source is not feasible, since it requires a large number of high resolution simulations. We approximate the functionally complex and computationally expensive high resolution tsunami simulations with a simple and cheap statistical emulator. A workflow integrating the entire chain of components from the tsunami source to quantification of hazard uncertainties is developed here - quantification of uncertainties in tsunamigenic earthquake sources, high resolution simulation of tsunami scenarios using the GPU version of Volna-OP2 on a non-uniform mesh for an ensemble of sources, construction of an emulator using the simulations as training data, and prediction of hazard intensities with associated uncertainties using the emulator. Thus, using the massively parallelized finite volume tsunami code Volna-OP2 as the heart of the workflow, we use statistical emulation to compute uncertainties in hazard intensity at locations of interest. Such an integration also balances the trade-off between computationally expensive simulations and desired accuracy of uncertainties, within given time constraints. The developed workflow is fully generic and independent of the source (1945 Makran earthquake) studied here.
Technological process for the production of flour confectionery is quite laborious, especially if sponge dough method is used. This method is used for the production of various bakery products, such ...as buns, pies, open pies and many others, during the production of which the proofing process can last for an hour. Muffins have been chosen as the object of the research due to their great popularity among the population and their use as pieces for the further manufacture of various confectionery products.A lot of research has been done on the intensification of the production process of small-sized bakery and flour confectionery products. The authors of the article have investigated the use of ultrasonic processing at the stage of preparation of the dough, in connection with the known positive results of the application of sonochemical technologies in the production of bakery products. The aim of the work has been the experimental determination of the operating parameters of the ultrasonic installation to prove the effectiveness of its use at the stage of preparation of the dough.The tasks included to conduct an experimental study on the development of technology for the manufacture of muffins using ultrasonic processing at the stage of proofing the dough. The analysis of the obtained data has shown that due to the use of ultrasound it has been possible to reduce the fermentation time of the dough, to improve the taste and aromatic parameters of the products obtained during sensory analysis.
In the American society in the 19th century, still prevailingly Christian, proclamations of faithlessness and calls for a purely scientific worldview occasionally appeared. Religion was perceived as ...an obstacle to efforts toward scientific materialism. A leading representative and popularizer of such an attitude was the American humanist, thinker, orator and lawyer Robert Green Ingersoll, whose works have been translated into many languages, including Czech. Ingersoll became a very popular figure, inspiring freethought circles both in the United States and in Europe. As a keen critic of religion, he ranked among the key American advocates for free thought, humanism, and the propagation of scientific knowledge. The paper discusses his specific form of faithlessness (agnosticism rather than atheism) and introduces a typology categorizing strategies of his criticism of the religious worldview in the context of Czech intellectual and freethinking movement of the first third of the 20th century.
Sheep's wool and leather shavings tanned without chromium (III) salts would be suitable for fertilization in organic farming, where is the lack of easily accessible fertilizer nitrogen. This ...hypothesis was tested in a two-year field experiment growing asparagus at Rogelj organic farm in Kranj (Slovenia). The block designed experiment with three replicates comprised fertilization treatments with sheep's wool (W), leather shavings (L), cattle manure (FYM) and unfertilized (Ø). Doses of fertilizers were relevant to 0 (Ø), 140 (W1, L1), 280 (W2, L2, FYM) and 560 kg (W3, L3) N/ha. Fertilizers were dosed the first year before the start of the vegetation. Within the next year we followed their subsequent effect. The highest soil mineral N was found in the W2, which produced also the highest asparagus yield (nonsignificant) in the first year. On contrary, NO
-N content in the asparagus crop was small what reflects the good synchrony of N mineralization and consumption of N at W2. Treatments W and L released significantly more N in the next year than the same dose of nitrogen from FYM. The experiment showed that mainly sheep wool represents a quality alternative organic fertilizer.
Ovčja volna in ostružki usnja strojenega brez kromovih (III) soli bi bili lahko primerni za gnojenje v ekološkem kmetijstvu, kjer primanjkuje gnojil z lahko dostopnim dušikom. To hipotezo smo preverjali v dvoletnem poljskem poskusu z vzgojo špargljev na ekološki kmetiji Rogelj v Kranju. V bločnem poskusu smo v treh ponovitvah obravnavali gnojenje z ovčjo volno (W), ostružki usnja (L), govejim hlevskim gnojem (FYM) ter negnojeno (Ø). Odmerki gnojil so ustrezali 0 (Ø), 140 (W1, L1), 280 (W2, L2, FYM) in 560 kg (W3, L3) N/ha. Gnojila smo odmerili prvo leto pred začetkom vegetacije, v naslednjem letu pa spremljali njihov naknadni učinek. V tleh je bilo največ mineralnega dušika pri W2, tudi pridelek je bil največji, vsebnost NO
-N v pridelku špargljev pa je bila majhna, kar kaže na dobro sinhronost mineralizacije in porabe N. Obravnavanji W in L sta imeli tudi v naslednjem letu značilno večje sproščanje N kot enak odmerek dušika iz FYM. Poskus je pokazal, da predvsem ovčja volna predstavlja kakovostno alternativno organsko gnojilo.
