Factors affecting the production of putrescine from agmatine by Lactobacillus hilgardii X1B isolated from wine
2008
Aims: To elucidate and characterize the metabolic putrescine synthesis pathway from agmatine by Lactobacillus hilgardii X1B. Methods and Results: The putrescine formation from agmatine by resting cells (the normal physiological state in wine) of lactic acid bacteria isolated from wine has been determined for the first time. Agmatine deiminase and N-carbamoylputrescine hydrolase enzymes, determined by HPLC and LC-Ion Trap Mass Spectrometry, carried out the putrescine synthesis from agmatine. The influence of pH, temperature, organic acids, amino acids, sugars and ethanol on the putrescine formation in wine was determined. Conclusions: Resting cells of Lact. hilgardii X 1B produce putrescine …
Regulation of hdc expression and HDC activity by enological factors in lactic acid bacteria.
2008
Aims: The aim of this work was to study the influence of enological factors on the histidine decarboxylase gene (hdc) expression and on histidine decarboxylase enzyme (HDC) activity in Lactobacillus hilgardii, Pediococcus parvulus and Oenococcus oeni. Methods and Results: Cell extracts and whole cells were used. Glucose, fructose, malic acid and citric acid diminished the hdc expression. Ethanol did not increase hdc expression or activity in cells, but increased HDC activity. Temperature and pH had effect on the activity of HDC but not on hdc expression. Tartaric acid and l-lactic acid, and sulphur dioxide (SO2) had no effect on enzyme synthesis and activity. Bacterial species differ in t…
Kasvisten, hedelmien ja marjojen syömisen lisääntyminen ryhmäohjauksessa
2017
Tämän tutkimuksen tarkoituksena oli selvittää Keski-Suomen alueella toteutettuun ryhmäohjaukseen osallistuneiden ryhmäläisten kasvisten syömistä 12 kuukauden aikana. Tavoitteena oli tutkia tuoreiden kasvisten, kypsennettyjen kasvisten sekä hedelmien ja marjojen käyttöä ja niiden syönnissä tapahtunutta muutosta. Lisäksi selvitettiin, miten sukupuoli, paino, painoindeksi, vyötärönympärys ja elämäntilanne ovat yhteydessä kasvisten syömiseen sekä miten yksilön aikomus muuttaa ruokakäyttäytymistä vaikuttaa itse muutoksen tekemiseen. Tutkimus on osa Keski-Suomen alueella toteutettua ryhmäohjausta (2011-2016) ja tutkimusaineisto kerättiin kyselylomakkeella alku- (0 kk), väli- (6 kk) ja loppumittau…
Regional metacommunities in two coastal systems: spatial structure and drivers of plant assemblages
2014
Aim Biogeographical patterns in metacommunities are still poorly understood, and different processes are expected to occur in different habitats. We analysed the regional plant metacommunities of coastal habitats to test whether (1) the influence of space and climate differs between two habitats differentiated along the seashore–inland gradient, and (2) regional variation in species composition of these habitats can be ascribed to different metacommunity paradigms. Location The entire coast of the Iberian Peninsula, south-western Europe. Methods We collected data on the plant species composition of coastal sites on sand dunes across 3000 km of coastline. The sites were classified into two h…

2016
Maģistra darba mērķis ir noskaidrot, vai velosipēdistu riskanta braukšana ir saistīta ar naivajiem priekšstatiem par fizikas likumiem. Pētījumā piedalījās 123 respondenti vecumā no 17 līdz 57 gadiem. Pētījumā tika izmantotas metodikas: Velosipēdistu uzvedības aptauja, modificēta, par pamatu ņemot Finstras un kolēģu (Feenstra et al. ,2011) izveidoto “Jauniešu velosipēdistu uzvedības aptauju” (Adolescent Cycling Behavior Questionnaire (ACBQ). Modifikāciju veica Eniņa, 2012, un Naivās fizikas uzdevumi ar grafisko attēlojumu no pētījuma „Naivas teorijas par kustību” (Naive Theories of Motion, McCloskey, Department of Psihology, John Hopkins University, 1982) sagatavoja Mališeva,2012.

L'attuazione della direttiva sulla vendita dei beni di consumo nel diritto italiano
2004
Il saggio si concentra sull'impatto della drettiva 1999/44 CE nel diritto italiano a ridosso del recepimento e della orginaria scelta di novellare la disciplina codicistica della vendita con l'inserimento degli artt. 1519 bis e seguenti. L'esito ricostruttivo di maggiore evidenza risiede nella decisa riconduzione della responsabilità del venditore fuori dall'ambito della garanzia e nell'area della responsabilità contrattuale; i rimedi offerti al compratore- consumatore si iscrivono entro il consueto rapporto da genus a species che nel codice civile italiano caratterizzala disciplina generale dell'inadempimento contrattuale e le sue "deviazioni" in aderenza ai divertsi tipi contrattuali.
LA VENDITA DI BENI DI CONSUMO TRA OBBLIGAZIONE E GARANZIA
2006
Il saggio affronta il tema della natura del vincolo del venditore di beni di consumo e si traduce in una riflessione sulle caratteristiche dell'obbligazione e della garanzia come istituti alternative per attribuire rilevanza giuridica ad un interesse. L'attenzione si sposta poi sull natura e sul contenuto dei rimedi previsti dal sistema gerarchico, affrontando il problema, ben poco esplorato, dell'enforcement dei rimedi ripristinatori
The Effects of General and Mobile Online Shopping Skilfulness and Multichannel Self-Efficacy on Consumer Showrooming Behaviour
2022
Although showrooming behaviour is a characteristic aspect of modern omnichannel retailing, our understanding of its antecedents remains limited. In this study, we aim to address this gap in prior research by examining how showrooming behaviour is affected by three different kinds of perceived consumer capabilities: general online shopping skilfulness, mobile online shopping skilfulness, and multichannel self-efficacy. The examination is done by utilising data from 1,024 Finnish consumers, which was collected with an online survey in 2021 and is analysed with structural equation modelling (SEM). In summary, we find mobile online shopping skilfulness to have a strong positive effect on showro…
Using AI to personalise emotionally appealing advertisement
2019
Personal data and information collected online by companies can be used to design and personalise advisements. This chapter extends existing research into the online behavioural advertising by proposing a model that incorporates artificial intelligence and machine learning into developing emotionally appealing advertisements. It is proposed that big data and consumer analytics collected through AI from different sources will be aggregated to have a better understanding of consumers as individuals. Personalised emotionally appealing advertisements will be created with this information and shared digitally using pragmatic advertising strategies. Theoretically, this chapter contributes towards…
Usage of Facebook- and Anonymous Forum–Based Peer Support Groups Online and Their Influence on Perceived Social Support Types in Weight Loss
2016
This paper contributes to the discussion on health behavior change support systems by examining one of the persuasive software features, social support. The paper studies the influence of structural social support on functional social support types in the online environment. Specifically, the paper examines the frequency of using two different kinds of online social platforms (online forums and Facebook groups) that are used to facilitate peer social support in weight loss and their influence on perceived functional social support types (emotional, informational, and instrumental). The results show that frequent use of Facebook based support peer group facilitates perceived emotional, infor…
