BROILER CHICKENS AND THEIR HEALTH STATUS IN FARM: WINE WASTE, AN ADDED VALUE ON FEEDING
2023
Various key economic sectors of the National and Sicilian economy, in addition to contributing to the economic growth also cause a considerable production of waste which today are a problem both for companies then for the environment. For this reason, there is considerable interest in this waste and in the possibility of their reuse to extract bioactive molecules with added value, all in accordance with the objectives of the Blue Economy. In this regard, it has already been demonstrated that from the production waste of various economic sectors it is possible to obtain bioactive molecules with anticancer, antimicrobial, cosmetic, antioxidant and nutraceutical properties (Mauro et al., 2022)…
Sustainable Supercapacitors Based on Polypyrrole-Doped Activated Biochar from Wood Waste Electrodes
2023
The synthesis of high-performance carbon-based materials from biomass residues for electrodes has been considered a challenge to achieve in supercapacitor-based production. In this work, activated biochar has been prepared as the active electrode material for supercapacitors (SCs), and an effective method has been explored to boost its capacitive performance by employing polypyrrole (PPy) as a biochar dopant. The results for physicochemical characterization data have demonstrated that PPy doping affects the biochar morphology, specific surface area, pore structure, and incorporation of surface functionalities on modified biochar. Biochar-PPy exhibited a surface area of 87 m2 g−1, while pris…
Understanding English word formation : a study among 6th-grade pupils in Finnish comprehensive school

Äitiys, huostaanotto ja voimaantuminen
2015
This study explores mothers’ experiences of their children’s custody. The empirical data consists of twelve interviews with mothers with a child custody experience. Seven interviews were conducted twice, in years 2004 and 2008. The purpose of the dissertation is three-fold: 1) to clarify the construction of motherhood before and after the custody; 2) to define what kind of support the mothers received after the children had been placed outside home; and 3) to identify promotive and hindering factors for the empowerment of these mothers. As for the method, this phenomenological study drew on qualitative content analysis. This dissertation sheds light on the reasons for child custody, as expr…
The reasons why the leaders of political parties are replaced. The Polish case
2015
Artykuł podejmuje kwestię przyczyn zmian przywódców w polskich partiach politycznych. Pod uwagę wzięto dwa główne czynniki, które – zgodnie z przyjętymi w środowisku naukowym poglądami – w sposób decydujący warunkują czas trwania na stanowisku. Po pierwsze, przeprowadzono analizę formalnych procedur związanych z odwoływaniem liderów partii politycznych zawartych w statutach partyjnych. Po drugie, przedstawiono wpływ wyniku wyborczego (uzyskane głosy i fakt zawiązania bądź nie koalicji gabinetowej) na zdolność liderów do utrzymania się na stanowisku. Analiza objęła partie polityczne, które uzyskały mandaty w wyborach do Sejmu przeprowadzonychw2011 r., a więc Prawo i Sprawiedliwość, Platformę…
Neiromediatora serotonīna ietekme uz augļu mušu (Drosophila melanogaster) kustību lateralitāti
2022
Augļu mušu (Drosophila melanogaster) depresīvā uzvedības modeļa izpēte ar y-tipa labirinta metodi, var palīdzēt saprast depresīvās uzvedības pamatelementus. Augļu mušas ir labi pazīstams un plaši pielietojams modeļobjekts bioloģijas nozares pētījumos, ir zināms, ka serotonīna sintēzes cikls ir evolucionāri konservatīvs, līdzīgs visiem dzīvniekiem, tāpēc ir svarīgi apzināties kādus ķīmiskos līdzekļus vislabāk pielietot tālakos uzvedības pētījumos. Darba mērķis ir izpētīt vai selektīvie serotonīna inhibitori ietekmē augļu mušu Oregon R kustību lateritāti. Kopā pētījumā analizēti, selektīvā serototonīna atpakaļpiesaistes inhibitora escitaloprāma un, vielas ar antidepresīvām īpašībām, triptofān…
Socio-technical risk governance through dyadic risk dialogue : copper corrosion as a safety challenge in the geological disposal of spent nuclear fuel
2014
The risk of corrosion in oxygen-free water has become an issue of scientific controversy possibly even threatening the realisation of the final disposal of spent nuclear fuel in Finland and Sweden. In Sweden there has been extensive discussion about the issue since 2007, but only recently has this debate increased in Finland although the similar disposal concept (KBS-3) is applied in both countries. In this report, we analyse how the implementer, Posiva (a Finnish nuclear waste company), and the regulator, STUK (the Finnish Radiation and Nuclear Safety Authority), have been engaged in a dialogue on the risk of copper corrosion. For over thirty years the implementer and regulator have been e…
Reflektio-osaamisen kehittyminen lastentarhanopettajaopintojen aikana
2014
Kotamäki, Leevi. 2014. Reflektio-osaamisen kehittyminen lastentarhanopettajaopintojen aikana. Varhaiskasvatustieteen kandidaatintutkielma. Kasvatustieteiden laitos. Jyväskylän yliopisto. 30 sivua + liite. Julkaisematon. Tämän tutkielman tehtävänä oli selvittää lastentarhanopettajaopiskelijoiden reflektio-osaamisen kehittymistä opiskeluiden aikana. Reflektio-osaaminen on Karilan ja Nummenmaan (2001) mukaan yksi päiväkotityön ydinosaamisalue. Tutkielman teoriaosiossa esitellään päiväkotityön keskeiset osaamisalueet sekä käsitellään reflektiota, reflektiivisyyttä ja reflektiivistä toiminitaa. Tutkimus suoritettiin kyselytutkimuksena, johon opiskelijat vastasivat sähköpostilla. Vastauksia tuli …
Analysis of the Potential of an Increase in Yeast Output Resulting from the Application of Additional Process Wastewater in the Evaporator Station
2019
This paper reports the results of an analysis of process wastewater streams in the context of an increase in yeast production. This research is based on the analysis of data from the biggest yeast factory in Europe. The research presented in this paper involves the analysis of the influence of direction of additional wastewater into the evaporator station on yeast production. In the process wastewater, nitrogen is mainly present in organic forms. The analysis reported in this paper involves the concentration of total nitrogen in wastewater streams, as it is the main parameter applied to determine the amount of wastewater that can be applied in agricultural fields. Directing additional waste…
Miksi korkeakoulutettu maahanmuuttanut ei pääse yliopistoon? : yhdenvertaisuutta etsimässä
2021
Eri tulkinnat yhdenvertaisuudesta ja sen täyttymisestä vaikuttavat siihen, kenellä on pääsy yliopisto-opintoihin. Samaa kaikille -ajattelu rajoittaa tukitoimien kohdentamista tietylle ryhmälle ja sysää vastuun hakukelpoisuuden edellyttämien tietojen ja taitojen saavuttamisesta yksilölle itselleen. Nykyisellään yliopistojen toimintamallit ja rakenteet eivät mahdollista korkeakoulutettujen ja korkeakoulukelpoisten maahanmuuttaneiden sujuvia polkuja yliopisto-opintoihin. Polkujen mahdollistamisessa keskeisessä roolissa ovat alkuvaiheen ohjauksen ja neuvonnan määrä ja laatu sekä suomen, ruotsin tai englannin kielen kehittämisen tuki niin yliopisto-opintoja edeltävän koulutuksen kuin yliopisto-o…
