Table olive wastewater as a potential source of biophenols for valorization : a mini review
2022
The table olive industry generates high amounts of wastewater annually during the alkaline treatment, fermentation, and washing steps of olives. High conductivity and salt content, as well as the high organic and biophenol contents of these waters, is a worldwide problem, especially in the Mediterranean region, which is the major table olive producing area. There is a wide variety of bioactives found in wastewater derived from table olive processing. The main compounds of table olive wastewater, such as those derived from phenolic, hydrocarbon, and sugar fractions, can be recovered and reused. In this review, the table olive manufacturing processes and the volumes and composition of wastewa…

Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements
2019
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral changes of individual animals and to the exclusion of species with long-range movements from areas with higher human impact. Global loss of vagility alters a key ecological trait of animals that affects no…
Improving Interpolants for Linear Arithmetic
2015
Craig interpolation for satisfiability modulo theory formulas have come more into focus for applications of formal verification. In this paper we, introduce a method to reduce the size of linear constraints used in the description of already computed interpolant in the theory of linear arithmetic with respect to the number of linear constraints. We successfully improve interpolants by combining satisfiability modulo theory and linear programming in a local search heuristic. Our experimental results suggest a lower running time and a larger reduction compared to other methods from the literature.
Water Consumption and Management in Schools in the City of Alicante (Southern Spain) (2000–2017): Free Water Helps Promote Saving Water?
2020
Studies on water in cities usually focus on household consumption. However, little attention has been given to non-household consumption and schools from a geographic perspective. The objectives of this research are to examine water consumption trends in schools in the city of Alicante (Southern Spain) between 2000&ndash
The relationship between stocking eggs in boreal spawning rivers and the abundance of brown trout parr
2015
Abstract Stocking with eggs has been widely used as a management measure to support degraded salmonid stocks. In Finland, Atlantic salmon and both sea-migrating and lake-migrating brown trout are stocked as eggs, alevins, fry, parr, and smolt, whereas trout are also stocked as mature fish. The aim of this stocking is to improve catches and to support collapsed spawning stocks. We assessed the success of stocking with brown trout eggs in a study of 17 Finnish boreal forest rivers, of which 9 were subject to egg stocking. All rivers contained some naturally spawning trout. In 16 rivers, including non-stocking years and unstocked rivers, egg stocking did not increase the total (wild and stocke…
Dynamic 2- and 3-connectivity on planar graphs
1992
We study the problem of maintaining the 2-edge-, 2-vertex-, and 3-edge-connected components of a dynamic planar graph subject to edge deletions. The 2-edge-connected components can be maintained in a total of O(n log n) time under any sequence of at most O(n) deletions. This gives O(log n) amortized time per deletion. The 2-vertex- and 3-edge-connected components can be maintained in a total of O(n log2n) time. This gives O(log2n) amortized time per deletion. The space required by all our data structures is O(n).
Pastaigas ar suni pilsētā: vienošanās par telpu un sociālā mijiedarbība
2021
Bakalaura darba "Pastaigas ar suni pilsētā: vienošanās par telpu un sociālā mijiedarbība" mērķis ir izpētīt desmit cilvēku, kuri ikdienā pastaigājas ar saviem suņiem Rīgas centrālajā daļā, neformālo praksi. Šīs tēmas nozīmīgums ir divējāds. Viens no iemesliem ir suņu adopcijas un iegādes pieaugums pandēmijas laikā, kas tiešā veidā attiecas uz vienošanās par telpu biežumu un intensitāti. Un otrs attiecas uz noteikumiem, kas ir spēkā, lai pārraudzītu šo praksi un to, kā tā īstenojas realitātē. Šī darba mērķis ir saprast, kā notiek tas, ka cilvēkiem, kuri pastaigājas ar suņiem, ir pastāvīgi jāvienojas par telpu, kā izskatās šīs telpas koplietošanas tikšanās un kā šī mijiedarbības prakse veido …
The effects of forest management on wood-inhabiting fungi occupying dead wood of different diameter fractions
2014
Forest management has caused severe ecological degradation throughout the Globe. One of its most prominent consequences is the drastic change in dead wood profile and consequently in the dead wood dependent biota. Wood-inhabiting fungi are, considering ecosystem functions, the most important species group utilizing dead wood, because they take care of majority of the decaying process. The earlier research focusing on the effects of forest management on wood-inhabiting fungi has strongly focused on large dead wood pieces (i.e. coarse woody debris, CWD), even though it has been shown that a major part of fungal diversity utilizes (also) small dead wood pieces (i.e. [very] fine woody debris, […
Els articles de Joan Fuster a 'Serra d’Or': «Restriccions mentals» (Primera sèrie: 1968-1973) i «Passar el dia, empènyer l’any» (Segona sèrie: 1978-1…
2021
La relació formal entre Joan Fuster i Serra d’Or, que durà, amb algun parèntesi enmig, vint-i-cinc anys (1959-1984), va donar com a fruit més de cent cinquanta articles. D’aquests, cent trenta van sorgir distribuïts equitativament en dues seccions: seixanta-cinc en la primera, «Restriccions mentals», que s’allargà des de l’abril de 1968 fins a l’agost de 1973, i seixanta-cinc més en la segona, «Passar el dia, empènyer l’any», que s’estengué des del febrer de 1978 fins al gener de 1984. Aquesta tesi doctoral té com a objectiu l’anàlisi literària d’aquest corpus d’articles tan delimitat. En primer lloc, s’hi realitza la justificació teòrica de l’adscripció de l’article literari en el gènere d…
