Effects of Packaging on Shelf-Life and Quality of Minimally Processed Fennel
2011
Fennel is not a widespread product among minimally processed vegetables, due to the fast deterioration mainly caused by browning of the cut surfaces, even during cold storage. In order to extend the shelf-life of fresh-cut fennel, the influence of different packaging techniques was studied. Sliced fennel, dipped in citric acid solution (0.5 %), was placed in polystyrene trays, sealed with PE film or vacuum packaged in PE bags and stored up to 14 days at 4°C. During this period weight loss, soluble solid content, pH, color and firmness were evaluated. Minimally processed fennel packed in sealed trays and coldstored at 4°C, extended its shelf life to 14 days maintaining acceptable quality. Fe…

Eutrophication reduces the nutritional value of phytoplankton in boreal lakes
2019
Eutrophication (as an increase in total phosphorus [TP]) increases harmful algal blooms and reduces the proportion of high-quality phytoplankton in seston and the content of ω-3 long-chain polyunsaturated fatty acids (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) in fish. However, it is not well-known how eutrophication affects the overall nutritional value of phytoplankton. Therefore, we studied the impact of eutrophication on the production (as concentration; μg L−1) and content (μg mg C−1) of amino acids, EPA, DHA, and sterols, i.e., the nutritional value of phytoplankton in 107 boreal lakes. The lakes were categorized in seven TP concentration categories ranging from ultra…
Foliar fertilization in ‘Nocellara del Belice’ olive trees
2008
Eight-year-old olive trees of ‘Nocellara del Belice’ grown in central Sicily were treated with five different types/combinations of organic and mineral foliar fertilizers. Floral 20-20-20 (mineral N, P, K, and microelements; FLO), Alga (extract of brown algae; ALG), FLO+ALG, Azomin (organic N, amino acids and peptides; AZO), Supernat93 (organic N and K, distillation residue; SUP), and water (CONTROL) were applied four times during summer and fall 2002. Yield and trunk circumference were measured during fall 2002, whereas other vegetative and reproductive parameters were measured during spring-fall 2003. AZO and SUP trees produced more than CONTROL and ALG ones, whereas only AZO trees showed…
Productive and vegetative responses of 'Gala' and 'Fuji' apple trees under controlled irrigation strategies
2008
We investigated the productive and vegetative responses of ‘Gala’ and 'Fuji' apple (Malus domestica Borkh.) trees to deficit irrigation and partial rootzone drying under the dry climate of central Sicily. Soil water tension (SWT), stomatal conductance, yield, fruit quality, fruit growth, and shoot extension of conventionally irrigated trees (CI), where drip emitters on both sides of each tree were left open, were compared to that of partial rootzone drying (PRD) trees, where only one side of the rootzone was irrigated for the entire season (receiving 50% of the CI irrigation water), and to that of deficit irrigated (DI) trees, where drip emitters on both sides of the rootzone were deliverin…
Granice języka a granice językoznawstwa
2016
Kwestię granic języka i lingwistyki autor rozważa, odwołując się do tzw. pełnej teorii naukowej. W złożonej hierarchiczno-sieciowej strukturze tej teorii można wyróżnić trzy poziomy; bazę filozoficzną, interpretacyjny obraz świata oraz część empiryczną. A następnie skupia uwagę na tej bazie, tj. na założeniach ontologicznych i epistemologiczno-aksjologicznych teorii języka. Wyróżnia cztery sposoby istnienia rzeczywistości językowej (konkretne teksty, system językowy, indywidualną i zbiorową świadomość językową), które pozostają we wzajemnych relacjach. Omawiając współczesną sytuację poznawczą w naukach humanistycznych i społecznych, przywołuje pojęcie paradygmat i zwrot oraz wskazuje na dom…
Possible influence of Zoophycos bioturbation on radiocarbon dating and environmental interpretation
2002
Abstract In paleoenvironmental studies of marine sediments bioturbation is often neglected and/or only treated as a diffusion-like process affecting only the uppermost sediment with decreasing intensity with depth. Deep dwelling animals, like the Zoophycos producing animal, however, affect the sediment composition by transporting material over vertical distances of up to 1 m below the seafloor. In Arabian Sea sediment cores 70KL, 64KL and 57KL a significant downward transport of particles by Zoophycos can be observed. Within the Zoophycos burrows the faunal composition of both planktonic and benthic foraminiferal assemblages as well as the isotopic signature of foraminiferal carbonate diffe…
Non-thermal pressure support in X-COP galaxy clusters
2018
Galaxy clusters are the endpoints of structure formation and are continuously growing through the merging and accretion of smaller structures. Numerical simulations predict that a fraction of their energy content is not yet thermalized, mainly in the form of kinetic motions (turbulence, bulk motions). Measuring the level of non-thermal pressure support is necessary to understand the processes leading to the virialization of the gas within the potential well of the main halo and to calibrate the biases in hydrostatic mass estimates. We present high-quality measurements of hydrostatic masses and intracluster gas fraction out to the virial radius for a sample of 12 nearby clusters with availab…
Success factors of game industry crowdfunding campaigns
2017
Tutkimuksen tarkoituksena oli selvittää mitkä ovat pelialan joukkorahoituskampanjoiden menestystekijöitä. Aiempaan joukkorahoitukseen sekä pelialaan keskittyneiden tutkimusten perusteella luotiin teoreettinen malli kuvaamaan tärkeimpiä menestystekijöitä ja niiden suhteita. Tätä mallia testattiin haastattelemalla kolmen eri joukkorahoituskampanjan perustajia. Aiemman teorian sekä haastattelujen perusteella selvisi, että pelialan joukkorahoituskampanjoilla on kuusi selkeää menestystekijää: kampanjan palkkiot, kampanjan tavoitteet, kampanjan sekä tuotteen laatu, projektitiimi, joukkorahoittajien luoma yhteisö sekä suoritetut esivalmistelut. Tutkimustuloksia ja niiden perus…
Density flow over networks: A mean-field game theoretic approach
2014
A distributed routing control algorithm for dynamic networks has recently been presented in the literature. The networks were modeled using time evolution of density at network edges and the routing control algorithm allowed edge density to converge to a Wardrop equilibrium, which was characterized by an equal traffic density on all used paths. We borrow the idea and rearrange the density model to recast the problem within the framework of mean-field games. The contribution of this paper is three-fold. First, we provide a mean-field game formulation of the problem at hand. Second, we illustrate an extended state space solution approach. Third, we study the stochastic case where the density …
