Functional inequalities for generalized inverse trigonometric and hyperbolic functions
2014
Various miscellaneous functional inequalities are deduced for the so-called generalized inverse trigonometric and hyperbolic functions. For instance, functional inequalities for sums, difference and quotient of generalized inverse trigonometric and hyperbolic functions are given, as well as some Gr\"unbaum inequalities with the aid of the classical Bernoulli inequality. Moreover, by means of certain already derived bounds, bilateral bounding inequalities are obtained for the generalized hypergeometric ${}_3F_2$ Clausen function.
Comparing Conservation Value Maps and Mapping Methods in a Rural Landscape in Southern Finland
2015
We tested to what extent conservation value maps are different if the valuation and mapping method is changed. We compared 66 different conservation value and 4 different ecosystem service maps. Using remote sensing and other georeferenced data, we produced 2 different habitat type maps, which were 50 % similar. We valued each mapped habitat type based on rarity corrected potential number of vascular plant species and naturalness using 6 different valuation alternatives. We mapped habitat type connectivity and complementarity using 2 main approaches. The habitat type valuation alternatives were quite similar, but if the habitat type naturalness was taken into account, differences were large…
Iron and pH regulating the photochemical mineralization of dissolved organic carbon
2017
Solar radiation mineralizes dissolved organic matter (DOM) to dissolved inorganic carbon through photochemical reactions (DIC photoproduction) that are influenced by iron (Fe) and pH. This study addressed as to what extent Fe contributes to the optical properties of the chromophoric DOM (CDOM) and DIC photoproduction at different pH values. We created the associations of Fe and DOM (Fe-DOM) that cover the range of loadings of Fe on DOM and pH values found in freshwaters. The introduced Fe enhanced the light absorption by CDOM independent of pH. Simulated solar irradiation decreased the light absorption by CDOM (i.e., caused photobleaching). Fe raised the rate of photobleaching and steepened…
Dynamic Sustainability. Sustainability Window Analysis of Chinese Poverty-Environment Nexus Development
2015
Sustainability Window is a new analysis tool for assessing the sustainability of development simultaneously in all of its three dimensions (environmental, economic, and social). The analysis method provides information of the maximum and minimum economic development that is required to maintain the direction of social and environmental development towards more sustainable targets. With the Sustainability Window method it is possible to easily analyze the sustainability using different indicators and different time periods making comparative analyses easy. The new method makes it also possible to analyze the dynamics of the sustainability and the changes over time in the width of the window.…
A Cluster Analysis Approach to Profile Men and Women’s Volley Positions in Professional Tennis Matches (Doubles)
2021
(1) Background: Tennis ball tracking technology allows the aquirement of novel and reliable data about several performance indicators, such as volley positions. This information is key to understand match dynamics in doubles tennis and to better help preparing players for the demands they will face in match play. As such, the purpose of this study was to describe and compare the different types of volley positions in men’s and women’s doubles professional tennis. (2) Methods: Ball tracking data were collected for 46 women (Billie Jean King Cup) and 96 men’s doubles matches (Davis Cup). The variables used were the distance to the net, the distance to the centre of the court and the height of…
Maallistuneet Madonnat ja 1800-luvun lopun käsityksiä materiaalisuudesta
2017
Edvard Munch (1864-1944) ja Axel Gallén (Akseli Gallen-Kallela) (1865-1931) tutustuivat toisiinsa Berliinissä vuonna 1895, jolloin he pitivät yhteisnäyttelyn Ugo Barroccio -taidegalleriassa. Yhteisnäyttelyssä taiteilijat esittelivät muun muassa omat versionsa madonna-aiheesta. Gallénin materiaalikuvauksessaan yksityiskohtainen ja vertauskuvallisuudessaan renessanssihenkiseksikin luonnehdittu, äitiyden onnea henkivä Madonna-teos sisältää runsaasti visuaalisia viitteitä Vienan Karjalaan, suomalaisen kansallismytologian alkulähteille. Taiteilija oli tehnyt häämatkansa Vienan Karjalaan pari vuotta ennen teoksensa valmistumista ja kuvasi teoksessaan vaimonsa Maryn ja tyttärensä Impi Marjatan. Mu…
Task-Specific Organic Salts and Ionic Liquids Binary Mixtures: A Combination to Obtain 5-Hydroxymethylfurfural From Carbohydrates
2019
The increase in energy demand and depletion of fossil fuels are among major issues of modern society. Valorization and transformation of raw materials in products of industrial value represents a challenge. This justifies the growing interest of scientific research towards the identification of suitable media and methodologies able to pursue above goals, paying attention to matter of sustainability. On this subject, we studied sulfonic-acid functionalized diimidazolium salts as catalysts for the conversion of fructose and sucrose to 5-hydroxymethylfurfural (5-HMF) in an ionic liquid mixture. In general, using these salts allowed us to obtain 5-HMF in good yields from both substrates in mild…
“La tonadilla a la Barcelona del darrer terç del Set-cents més enllà de la Casa de Comèdies"
2014
Resum: Encara que el monopoli oficial dels espectacles teatrals a la Barcelona del Set-cents era en mans de l’Hospital de la Santa Creu, és sabut que l’afició dels barcelonins pel teatre anava més enllà de la Casa de Comèdies gestionada per aquesta entitat. En el present article es mostren diversos casos que manifesten l’interès del públic barceloní per la tonadilla, gènere lírico-escènic breu importat a la Ciutat Comtal per imitació dels teatres madrilenys. Aquest interès ultrapassava l’escenari de la Casa de Comèdies, amb un curiós comerç dels textos i la possibilitat d’una pràctica privada. D’aquesta manera s’observa com aquest gènere importat pogué arrelar entre el públic barceloní, esp…
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
“Terve uni on kasvatuksella hankittavissa”. Nukkumisen ohjeistaminen 1800-1900-luvun vaihteen suomalaisissa terveysohjeissa
2017
Artikkelissa tarkastellaan sitä, miten nukkumista ohjeistettiin 1800-luvun lopun ja 1900-luvun alkukymmenten suomalaisessa terveysvalistuksessa ja mitä hyvän unen avulla tavoiteltiin. Artikkelissa kysytään myös, ketkä nukkumisohjeita laativat, kenelle ne oli suunnattu ja millaisesta ajattelutavasta ne kumpusivat. Unihygienia eli nukkumiseen ja liittyvät ohjeistukset olivat osa kansainvälistä hygienialiikettä, joka oli vahvimmillaan juuri 1800-luvun loppupuolella. Ne liittyvät myös suomalaiseen sivistyneistön kasvatusprojektiin, jonka tavoitteena oli vahva, terve ja siveellinen kansa. Artikkelin tutkimuslähteinä ovat terveysoppaat, terveydenhoitoalan lehdet ja nukkumiseen liittyvät ohjeistuk…
