Microstructure and characteristic properties of dogfish skin gelatin gels prepared by freeze/spray-drying methods
2020
International audience; The effects of two pretreatments (microwaves or oven-drying) on the dogfish (Squalus acanthias) skin as well as two drying processes (freeze-drying or spray-drying) on the extracted gelatins were studied. Thus six types of gelatins were obtained, three of which were freeze-dried (FG) and the others were spray-dried (SG), from the untreated skin (US), microwaves-pretreated skin (MS) and oven-pretreated skin (OS). The highest yield (8.67%) was obtained for the OSFG, while the lowest one (3.06%) was measured for the OSSG. Interestingly, all gelatins exhibited relatively high protein (84.02-89.53%), and low lipid (0.50-1.71%) and ash (3.05-7.17%) contents. In addition, g…
Digital solutions transform the forest-based bioeconomy into a digital platform industry : a suggestion for a disruptive business model in the digita…
2018
With the notion that the transformation of the forest-based bioeconomy in recent years provides insightful suggestions not only on the bioeconomy, but on business innovation, this paper conducts an empirical analysis of the transformation and attempts to extract suggestions for a digital-solution-driven, disruptive business model in the digital economy. Notwithstanding the potential broad cross-sectoral benefits, the natural environment, locality constraints, and incessant challenge of distance have impeded the balanced development of the bioeconomy. However, driven by digital solutions, the bioeconomy has taken big steps forward in recent years. Digitalization has enabled real-time, end-to…
Le clausole generali
2021
The essay aims the fundamental issue of general clauses as particular type of rule. The analyze then focuses on the valutative nature of the general clauses e the process of their concretization, called "valutative integration". Finally, the study deals with the distinction between general clauses, principles and values.
Study of the morphological affinity between two species of benthic foraminifera from restricted environments: Rosalina douvillei (Cushman, 1928) and …
2020
A biometric comparison is carried out on selected tests of the foraminiferal species Rosalina douvillei (Cushman, 1928) and Trichohyalus aguayoi (Bermudez, 1935). The Rosalina douvillei specimens were recovered from the marginal marine Oligocene/Miocene site of Russingen (Mainz Basin, Germany), the lacustrine beds of the lower Miocene site of Bunol (Valencian Community, Spain) and the middle/ upper Miocene site of Fuendetodos (Aragon, Spain). The Trichohyalus aguayoi tests were collected in the current coastal lagoon of Torreblanca and recovered from Holocene cores sampled in the Peniscola marsh and in the coastal lagoon of l’Albufera de Valencia, all them in the Valencian Community (Spain)…
Motivational Challenges of Engineers Participating in an Online Upskilling Program
2022
The present powerful surge of available online learning platforms will provide employees with enhanced opportunities to rapidly develop their skills, regardless of time and place. Despite the potential, there are challenges for participants on online learning platforms to finalise the courses they engage in. The reasons for the high number of students dropping out before completion of the course are motivational, social, and technological. Studies show that large skill gaps exist among industry employees worldwide. It is often caused by the implementation of new technologies, digitalization, as well as increasing requirements on sustainability and resilience. E-learning provides a major opp…
Alusveden hapetuksen vaikutukset Vesijärven pohjaeläimistöön - vuoden 2012 tulokset
2013
[Johdanto] Tämän Lahden Vesijärveä koskevan pohjaeläinselvityksen tavoitteena oli selvittää vuonna 2010 aloitetun laajamittaisen alusveden hapetuksen vaikutuksia järven syvännepohjaeläimistön tilaan. Hapetuksen vaikutusten esiin saamiseksi hapetusvuosien tilaa verrattiin vuonna 2009 tehtyyn esiselvitykseen (Hynynen & Salmelin 2010), jossa selvitettiin Lahden Vesijärven pohjaeläimistöä ennen järven syvänteiden hapetusta sekä kahden ensim-mäisen hapetusvuoden tuloksiin (Hynynen 2011, Tolonen & Hynynen 2012). Lahden edustalla sijaitsevaa Enonselän syvännealuetta hapetetaan yhdeksällä päällysvettä alusveteen pumppaavalla hapettimella (Salmi et al. 2010). Hankkeista vastaa Lahden kaupungin tekni…
Alusveden hapetuksen ja PHOSLOCK-käsittelyn vaikutukset Kymijärven syvännepohjaeläimistöön - vuoden 2012 tulokset.
2013
[Johdanto] Tämä toinen Kymijärven syvännepohjaeläimistöä koskeva tutkimus toteutettiin syksyllä 2012. Tutkimuksen tarkoituksena oli selvittää järven kunnostustoimena toteutetun hapetuksen sekä kesällä 2012 suoritetun PHOSLOCK-käsittelyn vaikutuksia Kymijärven syvänteiden pohjaeläimistöön ja ekologiseen tilaan. Järven pohjoista Myllypohjan syvännettä on hapetettu kesästä 2008 alkaen hapekasta päällysvettä alusveteen pumppaavalla Mixox-hapettimella (Kukkonen 2011). Alkukesästä 2012 eteläisessä Lapinkiven syvänteessä on järven kunnostustoimena lisäksi toteutettu PHOSLOCK-käsittely, jossa bentoniittisaveen liitetyt lantaani kationit (La³⁺) sitovat pohjaan laskeutuessaan valtaosan veden reaktiiv…
On personalized adaptation of learning environments
2017
This work is devoted to the development of personalized training systems. A major problem in learning environments is applying the same approach to all students: i.e., teaching materials, time for their mastering, and a training program that is designed in the same way for everyone. Although, each student is individual, has his own skills, ability to assimilate the material, his preferences and other. Recently, recommendation systems, of which the system of personalized learning is a part, have become widespread in the learning environments. On the one hand, this shift is due to mathematical approaches, such as machine learning and data mining, that are used in such systems while, on the ot…
The eastern regions of Al-Andalus before the conquest by Catalonia-Aragon: An overview
2012
This article sets forth a highly schematic synthesis of current knowledge on the history of the eastern regions of Al-Andalus, particularly Tortosa, Valencia and the Balearic Islands, before they were conquered by the Crown of Aragon between the 12th and 13th centuries. After presenting the informational records on this region, we shall describe the main features in the construction of a society and a political order grounded on Arab-Berber immigrants and the creation of a new agrarian ecosystem. Finally, we shall offer observations of the nature of the legal power and the forms in which authority was exercised.
