Latviešu studentu korporācijas Fraternitas Lettica saime ierodas Rīgas Meža kapos uz profesora Aleksandra Būmaņa kapakmeņa atklāšanu
1991
The Latvian Student fraternity Fraternitas Lettica, accompanied by its guard of honour, arrives at the Riga Forest Cemetery to participate in the unveiling of the tombstone of its member, Alfrēds Būmanis, Latvian lawyer and professor of law at the Faculty of Economics and Law of the University of Latvia. The unveiling of the tombstone coincides with the collapse of the USSR and the restoration of Latvia's independence.
Effect of Hormones on Sucrose Uptake and on ATPase Activity of Citrus sinensis L. Osbeck Leaves
1994
Carbohydrate accumulation in young, fully expanded leaves of Citrus sinensis L. Osbeck is affected by the presence of the fruitlet on the shoot. Previous work gave evidence that gibberellins may be involved in this 'fruit effect'. In the present work we have studied the effect of gibberellic acid (GA3) on 14C-sucrose uptake by leaf discs and whether its action could be due to a modulation of the plasma membrane ATPase, which maintains the H+ gradient that drives H+/sucrose co-transport. The effect of GA3 on 14C-sucrose uptake depended on the osmolarity of the assay medium. At 300 mOsm a reduction in the uptake rate was observed. The inhibitory effect of the hormone disappeared after preincu…
Hormone directed sucrose transport during fruit set induced by gibberellins in Pisum sativum
1987
A new system has been developed to study hormone-directed transport in intact plants during parthenocarpic fruit set induced by gibberellins. Gibberellic acid (GA3) and gibberellin A1 (GA1) applied to unpollinated ovaries of pea (Pisum sativum L. cv. Alaska) promoted sucrose transport from the leaf to the site of hormone application. In vivo experiments showed an early (30 min) accumulation of [14C]-sucrose in ovaries of pea stimulated by gibberellins. This activation of sucrose transport appears to be mediated by gibberellins (GA1, GA3), increasing both loading of phloem with sucrose in the leaf (source) and sucrose unloading in the ovary (sink). The ability of pea tissue segments to take …
On the gonality and the slope of a fibered surface
2018
Abstract Let f : X → B be a locally non-trivial relatively minimal fibration of curves of genus g ≥ 2 . We obtain a lower bound of the slope λ ( f ) increasing with the gonality of the general fiber of f. In particular, we show that λ ( f ) ≥ 4 provided that f is non-hyperelliptic and g ≥ 16 .
Automorphisms of $mathbb{A}^{1}$-fibered affine surfaces
2011
We develop technics of birational geometry to study automorphisms of affine surfaces admitting many distinct rational fibrations, with a particular focus on the interactions between automorphisms and these fibrations. In particular, we associate to each surface S of this type a graph encoding equivalence classes of rational fibrations from which it is possible to decide for instance if the automorphism group of S is generated by automorphisms preserving these fibrations.
Tacitus on Titus? Visit to the Temple of Venus at Paphos
2020
This article deals with Titus? visit to the temple of Venus at Paphos in the second book of Tacitus? Historiae. I argue that apart from its other literary intentions already mentioned by scholars, this digression implicitly connects Titus not only with Aeneas but also with Julius Caesar. Titus? affair with Berenice that recalls Caesar?s affair with Cleopatra, Tacitus? allusions to Lucan?s De Bello Civili where Caesar?s visit to the tomb of Alexander the Great is described, the ?????Motiv and fortuna?s favour that characterise both Roman generals, all contribute to connect Titus with Caesar and allow the reader to view a parallel between the Flavian and the Julio-Claudian dynasty.

Identidad y desarrollo en los bereberes de Marruecos: transformaciones y contradicciones entre los Ait Haddidou
2005
Los Ait Haddidou son un grupo étnico bereber de carácter tribal que habitan en el Valle del Assif Melloul, región ubicada en el Alto Atlas Oriental de Marruecos. Este área se ha caracterizado por el aislamiento en el que han permanecido durante largo tiempo sus habitantes. Los Ait Haddidou han conformado su identidad a lo largo de todo un proceso histórico, que fundamentalmente se ha caracterizado por su enfrentamiento al poder central del Estado (apoyado éste principalmente por los grupos de origen árabe que habitan en el país). El Estado ha empleado diversas estrategias para debilitar la unidad y fuerza de este grupo tribal con el fin de poder extender así mejor su dominio en la región, e…
The genesis of data-driven decision-making in the world of soccer tactics : deciphering the potential of big data
2021
Master's thesis in Information systems (IS501) Arguably, soccer is a more fluid sport than other popular sports such as baseball, American football, and cricket, which explicitly require more discrete ‘plays.’ Moreover, with twenty-two players always committed, it has more moving elements than basketball or ice hockey. From a mathematical perspective, this signifies that soccer has more degrees of freedom than these other sports, making it difficult to evaluate the game using one or a small number of metrics. Over time, this challenge has been made exceedingly more difficult within the soccer community. The availability of data has increased much more rapidly than the scientific advancement…
Flerkanals multimedia over IP
2001
Masteroppgave i informasjons- og kommunikasjonsteknologi 2001 - Høgskolen i Agder, Grimstad Denne diplomoppgaven tar for seg multimedia over IP ved bruk av videokonferanse. To møterom blir forsøkt innredet med høykapasitets videokonferanseutstyr med flere parallelle videokanaler. Ideen er å benytte disse til å øke den sosiale nærheten og unnvike kikkehullseffekten, slik at man kan utnytte dette til å skape bedre rammer for kreativt samarbeid på tvers av lange distanser. Vi diskuterer oppstilling av utstyr med bruk av et godt videokonferanseverktøy, måter å øke muligheten for øyekontakt og det å kunne henvende seg til den enkelte i et møte. Vi rapporter enkelte brukererfaringer og lærdommer …
Ontological representation of texts, and its applicationsin text analysis
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad For the management of a company, the need to know what people think of their products or services is becoming increasingly important in an increasingly competitive market. As the Internet can nearly be described as a digital mirror of events in the ”real“ world, being able to make sense of the semi structured nature of natural language texts published in this ubiquitous medium has received growing interest. The approach proposed in the thesis combines natural language processing and ontologies to represent elements in texts and relations between them. These relations are used to determine what terms …
