Promotion of Social Policies – an Investment in the Future: Canada – European Union – Baltic States – Nordic Countries
2009
This volume represents presentations, discussions and research papers in conjunction with the Forum for a Comparative Dialog- an Investment in the Future. The Forum was held in Riga at the University of Latvia on November 6-8, 2008 and was organised by the Centre for European and Transition Studies at the University of Latvia and Capilano University, Canada.
Higher Education from a Longitudinal and Life Course Perspective
2015
International audience; This symposium brings together scholars from across Canada, Europe, and the United States to explore how longitudinal and life course research can be used to study higher education. Highlighting both qualitative and quantitative research, we will explore aspects of social reproduction, inequality, stratification, wellbeing, and school-to-work transitions.

Ion-exchange fibers and drugs: an equilibrium study
2001
The purpose of this study was to investigate the mechanisms of drug binding into and drug release from cation-exchange fibers in vitro under equilibrium conditions. Ion-exchange groups of the fibers were weakly drug binding carboxylic acid groups (-COOH), strongly drug binding sulphonic acid groups (-SO(3)H), or combinations thereof. Parameters determining the drug absorption and drug release properties of the fibers were: (i) the lipophilicity of the drug (tacrine and propranolol are lipophilic compounds, nadolol is a relatively hydrophilic molecule), (ii) the ion-exchange capacity of the fibers, which was increased by activating the cation-exchange groups with NaOH, (iii) the ionic streng…
Retention of vanadium (V) by three Finnish mineral soils
1994
Summary Retention of V(V) by three Finnish mineral soils from 10−4m and 10−5m sodium vanadate solutions was investigated at room temperature in the pH range 2.3–7.5. In adsorption experiments, 0.02 m KCl was used as ionic medium, and the samples were left to equilibrate for 72 h. The solid: solution ration was 1:100 (m: v). Maximum adsorption occurred at pH ∼4, where 70–80% of the added V (350–400 μg g−1 from 10−4m solution and 35–40 μg g−1 from 10−5m solution) was retained by each soil. Retention was significant even at pH 6, where adsorption of a similar anion, molybdate, is negligible. Desorption of the retained V was measured by adding 50.0 cm3 of 0.02 M KCl into weighed soil samples an…
Solidago canadensis un Heracleum sosnowskyi ēterisko eļļu herbicidālā un fungicidālā iedarbība
2022
Strauja invazīvo augu sugu izplatīšanās tiek uzskatīta par vienu no galvenajiem bioloģiskās daudzveidības samazināšanās virzītājspēkiem, kā rezultātā tiek traucēta ekosistēmu pakalpojumu nodrošināšana, kas rada negatīvas ekoloģiskās sekas, ekonomiskus zaudējumus un kaitējumu cilvēka veselībai. Invazīvo augu sugu ierobežošana ir dārga un bieži vien ekonomiski neizdevīga, kā arī ķīmiskā ierobežošana var radīt draudus cilvēkam, tāpēc izdevīgāk būtu šīs sugas ilgtspējīgi izmantot, vienlaikus cenšoties nepieļaut jaunu invazīvo augu sugu ienākšanu Latvijā. Latvijā izplatītāko invazīvo augu sugu Sosnovska latvāņa un Kanādas zeltslotiņas augu daļas ir bagātas ar ēterisko eļļu, kurai var būt herbici…
Towards Axiomatic Basis of Inductive Inference
2001
The language for the formulation of the interesting statements is, of course, most important. We use first order predicate logic. Our main achievement in this paper is an axiom system which we believe to be more powerful than any other natural general purpose discovery axiom system. We prove soundness of this axiom system in this paper. Additionally we prove that if we remove some of the requirements used in our axiom system, the system becomes not sound. We characterize the complexity of the quantifier prefix which guaranties provability of a true formula via our system. We prove also that if a true formula contains only monadic predicates, our axiom system is capable to prove this formula…
Letters in Arabic sent from the Nasrid Court. A diplomatic analysis
2018
El trabajo aplica las técnicas de la ciencia Diplomática a la correspondencia enviada desde la corte nazarí de Granada a monarcas y señores de los reinos de Aragón y Castilla. Por razones de coherencia y espacio, se centra únicamente en las misivas redactadas en árabe. El objetivo es establecer sus caracteres extrínsecos (tamaño y color del papel, tipo de letra, características del sello, presencia o no deʽalāma) e intrínsecos (manera de dirigirse al destinatario, manera de presentarse, saludos, tipo de datación tópica y crónica), comprobar si con el paso del tiempo hubo evolución en las fórmulas y si se refleja en éstas la categoría social de remitente y destinatario. Las fuentes empleadas…
