Diversifying crop rotations with temporary grasslands: potentials for weed management and farmland biodiversity
2010
Fruchtfolgen können dazu dienen, die kontinuierliche Selektion von Unkrautarten zu verhindern, die an eine bestimmte Kultur angepasst sind. Dies könnte dem Unkrautmanagement, der Einsparung von Herbiziden, und der Biodiversität dienen. Heutige, sehr einfache Furchtfolgen könnten durch mehrjährige Futterkulturen diversifiziert werden. Die Einflüsse solcher mehrjähriger Kulturen auf Unkräuter wurden in vier Ansätzen untersucht : 1) Vegetationsaufnahmen auf 632 Feldern in Westfrankreich zeigten, dass die Unkrautzusammensetzung zwischen mehrjährigen Futterkulturen und einjährigen Kulturen stark variiert. Der Vergleich von Feldern vor, während und nach mehrjährigen Futterkulturen legte nahe, das…
Periodontal Behavior Around Teeth Prepared with Finishing Line for Restoration with Fixed Prostheses. A Systematic Review and Meta-Analysis
2020
Background: The objective of this systematic review and meta-analysis was to analyze the periodontal behavior around teeth prepared with horizontal finishing crowns supporting fixed metal-ceramic and zirconia full coverage crowns and fixed partial dentures (FDPs). Materials and methods: An electronic search was conducted to locate relevant clinical trials in four databases: PubMed, Embase, Cochrane, and Scopus. A manual search was made in the reference sections of the articles identified for any additional articles. No restrictions were applied regarding year of publication or language. The following variables were considered in quantitative and qualitative analysis: probing pocket depth (P…
Neutron Radiography Visualization of Solid Particles in Stirring Liquid Metal
2015
Abstract This paper presents the analysis of the first dynamic neutron radiography experiment that visualized motion of solid particles in liquid metal, which was stirred by a system of four counter-rotating magnets. The paper also contains the quantitative results derived from neutron images: the distribution of particle concentration, number of admixed particles and velocities as functions of the magnet rotation speed.
El concurso de acreedores en persona física
2015
El propósito de dicha tesis doctoral ha sido doble, por un lado se han abordado los antecedentes históricos desde la época romana para entender bien el origen del concurso de acreedores que se utilizaba en supuestos de insolvencia de la persona física y su diferenciación de la quiebra y de la suspensión de pagos, ambos supuestos de insolvencia del comerciante que se regulaban en el Código Civil de 1889, en la LEC de 1881 y en el Código de Comercio de 1829 hasta que la Ley Concursal reguló en un solo cuerpo legal tanto la insolvencia de las personas físicas como de las personas jurídicas y tanto fueran comerciantes como no lo fueran. Y, por otro lado, se han estudiado las Leyes actuales, par…
Influence of bioremediation stimulators in soil on development of oat seedlings (Avena sativa) and their aminopeptidase activity
2015
Dobór technik bioremediacji jest bardzo ważny w oczyszczaniu gleby skażonej substancjami ropopochodnymi, która ma być wykorzystywanej rolniczo. Prezentowane wyniki wskazują, że na rozwój siewek owsa większy wpływ ma stosowana metoda bioremediacji niż poziom zanieczyszczenia węglowodorami. Z zastosowanych technik najbardziej przyjazne dla wegetacji owsa były te, w których wykorzystywano szczepionkę drożdżową.
The role of light in the emergence of weeds: using Camelina microcarpa as an example
2015
When modelling the emergence of weeds, two main factors are considered that condition this process: temperature and soil moisture. Optimum temperature is necessary for metabolic processes that generate energy for growth, while turgor pressure is necessary for root and shoot elongation which eventually leads to seedling emergence from the soil. Most emergence models do not usually consider light as a residual factor, but it could have an important role as it can alter directly or indirectly the dormancy and germination of seeds. In this paper, inclusion of light as an additional factor to photoperiod and radiation in emergence models is explored and compared with the classical hydrothermal t…
Use of Biostimulants for Organic Apple Production: Effects on Tree Growth, Yield, and Fruit Quality at Harvest and During Storage
2018
The experiment was conducted during two consecutive seasons (years 2016 and 2017) in an organic apple orchard of the cultivar Jonathan. Several biostimulants were tested (10 in total), including humic acids, macro and micro seaweed extracts, alfalfa protein hydrolysate, amino acids alone or in combination with zinc, B-group vitamins, chitosan and a commercial product containing silicon. Treatments were performed at weekly intervals, starting from the end of May until mid-August. The macroseaweed extract was effective in stimulate tree growth potential in both years, as shown by a significantly larger leaf area (+20% as compared to control) and by an higher chlorophyll content and leaf photo…
Early evolutionary colocalization of the nuclear ribosomal 5S and 45S gene families in seed plants: evidence from the living fossil gymnosperm Ginkgo…
2012
In seed plants, the colocalization of the 5S loci within the intergenic spacer (IGS) of the nuclear 45S tandem units is restricted to the phylogenetically derived Asteraceae family. However, fluorescent in situ hybridization (FISH) colocalization of both multigene families has also been observed in other unrelated seed plant lineages. Previous work has identified colocalization of 45S and 5S loci in Ginkgo biloba using FISH, but these observations have not been confirmed recently by sequencing a 1.8 kb IGS. In this work, we report the presence of the 45S–5S linkage in G. biloba, suggesting that in seed plants the molecular events leading to the restructuring of the ribosomal loci are much o…
Kooperatīva mācīšanās kā līdzeklis 7-12 gadu vecu bērnu kapoeiras kustību iegaumēšanai
2020
Šajā maģistra darbā autore pētīja, vai kooperatīvā mācīšanās uzlabo kapoeira horeogrāfiju atcerēšanos. Autore organizēja 9 video novērošanas sesijas 7-12 gadus veciem kapoeira audzēkņiem Capokids Capoeira Latvia organizētajās nodarbībās. Trīs bērnu grupas strādāja katrā no trim mācību organizācijas formām: indivīduāli, grupu darbs, un darbs pāros. Kopumā pētījumā piedalījās 53 bērni. Autore analizēja bērnu sasniegumus un pētīja uzvedību. Papildus uzmanība tika pievērsta bērniem ar augstu sasniegumu līmeni un bērniem ar dažādām vajadzībām. Autore secināja, ka kooperatīvā mācīšanās uzlabo capoeira horeogrāfiju, atcerēšanos un papildus nodrošina bērniem iespēju apgūt sociālās prasmes. Darba re…
The Basic Psychological Needs in Physical Education Scale in Filipino: An Exploratory Factor Analysis
2014
Fulfillment of students’ basic psychological needs in school physical education is essential for their optimal motivation and well-being. The present study aimed to: (1) translate the Basic Psychological Needs in Physical Education Scale (BPNPE Scale; Vlachopoulos, Katarzi, & Kontou, 2011) to Filipino, and (2) examine the reliability and validity of the Filipino version. Instrument translation was conducted using a committee-approach back-translation procedure. The Filipino version was then administered to 408 public high school students from Metro Manila during one of their PE classes. Results showed that internal consistency reliabilities of the subscales were adequate with alphas ranging…
