Chlorophyll fluorescence, photosynthesis and growth of tomato plants as affected by long-term oxygen root zone deprivation and grafting
2020
A greenhouse experiment was conducted to study the effects of the O2 root zone level and grafting on chlorophyll fluorescence, photosynthesis and growth of cherry tomato grown in a hydroponic system. Two O2 concentrations in the root zone, namely Ox (saturation level) and Ox- (2&ndash
Hybrids and allied species as potential rootstocks for eggplant: Effect of grafting on vigour, yield and overall fruit quality traits
2018
Abstract Grafting of fruiting vegetables is an effective technique to overcome pests and diseases in modern cropping systems and it is often used to improve yield and fruit quality. Eggplant is an important vegetable crop that benefits significantly from grafting. In this regards, the exploitation, valorization and breeding of new rootstock genotypes as possible substitute to those commonly used (Solanum torvum and tomato hybrids) would permit an intensive eggplant crop system in those situations where a rootstock rotation is required. In the present article, we study the effects of several potential rootstocks including both wild/allied species of eggplant [S. torvum (STO), S. macrocarpon …
Rootstock and Arbuscular Mycorrhiza Combinatorial Effects on Eggplant Crop Performance and Fruit Quality under Greenhouse Conditions
2020
The herbaceous grafting of fruiting vegetables is considered a toolbox for safeguarding yield stability under various distresses and for improving fruit quality. Inoculation with arbuscular mycorrhiza (AM) fungi seems also to be an efficient tool for increasing the assimilation, uptake and translocation of macroelements and microelements, for modulating plant secondary metabolism and for overcoming several forms of plant distress. The present work evaluated the combined effect of grafting the &ldquo
Associations between parental food choice motives, health-promoting feeding practices, and infants' fruit and vegetable intakes: the Food4toddlers st…
2020
Background: Parents influence their infants' diets and are the providers of healthy foods such as fruit and vegetables. Parental motives can influence infant's diets directly or through parental feeding practices. Objective: This study aimed to assess the associations between parental food choice motives and infants' fruit and vegetable intakes and to examine whether parental feeding practices mediated these associations. Design: A total of 298 parents participated in the Norwegian Food4toddlers study. Before the child's first birthday (mean age = 10.9 months), the parents completed an online baseline questionnaire. Five parental food choice motives were assessed: health, convenience, senso…
Pitfalls of hypothesis tests and model selection on bootstrap samples: Causes and consequences in biometrical applications
2015
The bootstrap method has become a widely used tool applied in diverse areas where results based on asymptotic theory are scarce. It can be applied, for example, for assessing the variance of a statistic, a quantile of interest or for significance testing by resampling from the null hypothesis. Recently, some approaches have been proposed in the biometrical field where hypothesis testing or model selection is performed on a bootstrap sample as if it were the original sample. P-values computed from bootstrap samples have been used, for example, in the statistics and bioinformatics literature for ranking genes with respect to their differential expression, for estimating the variability of p-v…
Rammefaktorenes betydning for mat- og helseundervisningen på 1.–4. trinn
2021
Mat og helse har kompetansemål etter 4. trinn i norsk grunnskole, men få studier har sett på betydningen av rammefaktorer for undervisningen i mat og helse på barnetrinnet. I denne studien undersøker vi læreres og skolelederes oppfatninger av rammefaktorer og forskjeller mellom skolenes rammefaktorer, som lærerkvalifikasjoner, timeplanfestet undervisning, organisering, budsjett og utstyr. Data ble samlet inn gjennom 24 kvalitative intervju, fordelt på 9 med skoleledere og 15 med mat- og helselærere. Intervjuene ble gjennomført på 12 utvalgte praksisskoler fra alle landsdeler i Norge. Til tross for kort undervisningserfaring og manglende studiekompetanse i faget opplever både lærere og lede…
Changes in breaststroke swimming performances in national and international athletes competing between 1994 and 2011 -a comparison with freestyle swi…
2014
Abstract Background The purpose of the present study was to analyse potential changes in performance of elite breaststroke swimmers competing at national and international level and to compare to elite freestyle swimming performance. Methods Temporal trends in performance of elite breaststroke swimmers were analysed from records of the Swiss Swimming Federation and the FINA (Fédération Internationale de Natation) World Swimming Championships during the 1994–2011 period. Swimming speeds of elite female and male breaststroke swimmers competing in 50 m, 100 m, and 200 m were examined using linear regression, non-linear regression and analysis of variance. Results of breaststroke swimmers were …
Sex-related differences and age of peak performance in breaststroke versus freestyle swimming
2013
Abstract Background Sex-related differences in performance and in age of peak performance have been reported for freestyle swimming. However, little is known about the sex-related differences in other swimming styles. The aim of the present study was to compare performance and age of peak performance for elite men and women swimmers in breaststroke versus freestyle. Methods Race results were analyzed for swimmers at national ranked in the Swiss high score list (during 2006 through 2010) and for international swimmers who qualified for the finals of the FINA World Swimming Championships (during 2003 through 2011). Results The sex-related difference in swimming speed was significantly greater…
Atlantin ylityksiä : amerikkalaisen kirjallisuuden- ja kulttuurintutkimuksen navigointia 1965-1995
2011
Teoriat muuttuvat paitsi aikaa myös paikkaa myöten. Kirjassa tutkitaan eurooppalaisen, varsinkin ranskalaisen teorian Atlantin ylityksiä. Millaisiksi eräät keskeiset teoriaotteet muotoutuivat yhdysvaltalaisessa yliopistomaailmassa ja kohdatessaan uudet poliittiset ja kulttuuriset haasteet? Tämän muotoutumisen vaikutukset näkyvät vuorostaan muualla. Ajanjakso on 1965–1995. "Korkean teorian" nousu liittyi kielelliseen käänteeseen ja perustojen horjumiseen, ja sen erilaisten muotojen ja myös vastustamisen tarkastelu ulottuu kielen merkityksiä hajottavasta retorisuudesta valtarakenteiden marxilaiseen analyysiin, afrikkalaisamerikkalaiseen feminismiin ja "orientalismin" symboliseen tuottamiseen …
Bērnu sadzīves iemaņu veidošanās ģimenē
2015
Maģistra darba tēma ir “Bērnu sadzīves iemaņu veidošanās ģimenē”. Sadzīves iemaņas palīdz bērnam darboties patstāvīgi, ievirza bērnu “pieaugušo darbā”. Sadzīves iemaņas attīsta bērna fiziskās, intelektuālās un tikumiskās spējas. Šīs iemaņas tiek apgūtas caur bērnu praktisku darbošanos kopā ar pieaugušo vai patstāvīgi, caur rotaļām, kā arī ar pieaugušo parauga palīdzību. Maģistra darba mērķis ir teorētiski un praktiski izpētīt 2 – 3 gadus vecu bērnu sadzīves iemaņu veidošanās iespējas ģimenē.
