The Effect of Bialaphos on Ammonium-Assimilation and Photosynthesis II. Effect on Photosynthesis and Photorespiration

1989

Abstract The application of bialaphos (phosphinothricyl-alanyl-alanine) effects a quick photosynthesis inhibition under atmospheric conditions (400 ppm CO2, 21% O2). However, under conditions (1000 ppm CO2, 2% O2) under which photorespiration cannot occur there is no photosynthesis inhibition. In the previous investigation it could be shown that bialaphos splits in plants into phosphinothricin and alanine. The inhibition of glutamine synthetase through freed phosphinothricin results in an NH4 +-accumulation and a decrease in glutamine. With the addition of glutamine, photosynthesis inhibition by bialaphos can be reduced. An NH4 +-accumulation takes place under atmospheric conditions as well…

Le combat de Victor Schoelcher contre la légalité de l'esclavage : l'abolition de 1848

2009

How has the French State been able to maintain slavery for more than fifty years after the Déclaration des droits de l'homme et du citoyen of 1789? The slave was considered, in a legal scope, not as a person but as a « movable », he was considered as an object that could be bought, sold, mutilated and tortured! Abolished for the first time in 1794, reinstated in 1802 by Napoleon Bonaparte, slavery would definitively disappear in France only in 1848, thanks to Victor Schoelcher's (1804-1893) decisive action. This great humanist, by a tireless fight, managed to impose an immediate abolition – and not a progressive one as in Britain – showing that if this institution was certainly legal, it wa…

Victor Schoelcher, abolitionniste et républicain : approche juridique et politique de l'oeuvre d'un fondateur de la République

2000

The aim of this judicial and political analysis is to reveal Victor Schoelcher's decisive influence in the fight for equal rights and for the republic, in the French mainland as well as in its colonies. His well known fight against slavery was just a part of his humanist defense of the republican principles : Liberty, Equality, Fraternity. Schoelcher truly was a founder of the republic, taking part in the barricade insurrections against the 1851 coup and fighting against any kind of slavery or absolutism. His work addressed many aspects of our society, among which : - Slavery and the colonies (legal status of slaves, emancipated slaves and of the colonies) - Rights and liberties of men and …

L'abolitionnisme de Victor Schoelcher, un humanisme mâtiné de colonialisme et de moralisme

1999

Although this title might be somewhat provocative, there is no intent to be anti-schoelcherist. The aim is not to diminish Victor Schoelcher's considerable achievements, but to fight against the unanimous preconceptions that have transformed this man into a myth. By studying the legal and political consequences of his proposals and his engagements, we have underlined not only the extent and complexity of his work for the Republic - that has been little known up to now, though Schoelcher ought to be considered to be one of the fathers of the Republic - but his contradictions too. Schoelcher was so sure of the virtues of the republican values of the mother country, that his fight, albeit huma…

Cambios en el comercio exterior de los países del este. La difícil reinserción en Europa

1999

Changes in the foreign trade of the countries of the East. The difficult assimilation into Europe. The direction of the trading lines of the post-communist countries has been modified by the political and economical changes of the countries of the East of Europe, the dismantling of the COMECON, as well as by the disintegration of the USSR and the detente in the international relationships. During the forty years that the COMECON was prevailing, that region centred its attention on the USSR, but nowadays the East looiks at the West, concretaly at the European Union and more exactly at Germany. The composition of the imports and exports reveals the marked dependence on Central and Eastern Eur…

L‐Aspartate as a high‐quality nitrogen source in Escherichia coli : Regulation of L‐aspartase by the nitrogen regulatory system and interaction of L‐…

2020

Escherichia coli uses the C4-dicarboxylate transporter DcuA for L-aspartate/fumarate antiport, which results in the exploitation of L-aspartate for fumarate respiration under anaerobic conditions and for nitrogen assimilation under aerobic and anaerobic conditions. L-Aspartate represents a high-quality nitrogen source for assimilation. Nitrogen assimilation from L-aspartate required DcuA, and aspartase AspA to release ammonia. Ammonia is able to provide by established pathways the complete set of intracellular precursors (ammonia, L-aspartate, L-glutamate, and L-glutamine) for synthesizing amino acids, nucleotides, and amino sugars. AspA was regulated by a central regulator of nitrogen meta…

Acculturation Orientations among Russian Youth in Finland

2023

Despite the fact that much academic attention has been directed to the acculturation of immigrants in Finland, the need to more fully understand how immigrants cope with acculturation is timely. Since the Russian-speaking immigrants represent the biggest immigrant group in Finland, this chapter explores the acculturation orientations among Russian immigrant youth approached from the angle of the festive culture. The findings are based on the data of ethnographic observation and qualitative interviews (n 16) conducted in the central part of Finland. To capture the nuances of dynamic acculturation experiences, the authors applied a bottom-up methodological approach which gives voice to young …

Socially phobic clients' self-descriptions, treatment progress and reflexivity in short-term cognitive-constructivist group psychotherapy

2017

The aim of the research was to get information about different kinds of clients with social phobia and their therapeutic progress in cognitive-constructivist group psychotherapy. The aim was also to offer relevant information to clinicians working with socially phobic clients on how they could help the progress of the successful therapeutic change process of socially phobic clients, especially in early phases of the therapy when clients are developing a reflexive stance toward their own problematic experiences. Study I supported the view that negative self-image is central to social phobia, but this ranged from total piteousness to relatively few negative feelings of insufficiency. Three su…

Nitrogen uptake and nitrogen fertilizer recovery in old and modern wheat genotypes grown in the presence or absence of interspecific competition

2015

Choosing genotypes with a high capacity for taking up nitrogen (N) from the soil and the ability to efficiently compete with weeds for this nutrient is essential to increasing the sustainability of cropping systems that are less dependent on auxiliary inputs. This research aimed to verify whether differences exist in N uptake and N fertilizer recovery capacity among wheat genotypes and, if so, whether these differences are related to a different competitive ability against weeds of wheat genotypes. To this end, 12 genotypes, varying widely in morphological traits and year of release, were grown in the presence or absence of interspecific competition (using Avena sativa L. as a surrogate wee…
