Lithium nuclear-magnetic-resonance in lithium acetate dihydrate, Li(CH3COO).2H2O

Li n.m.r, in single crystals of lithium acetate dihydrate is used to determine the quadrupole coupling parameters: (e2qQ/h) and r/. The orientations of the principal z, y and x components of the electric field gradient tensor are determined to be along the crystallographic b, a and c axes respectively. The parameters experimentally determined are (e2qQ/h)= 154"6 kHz; and i/= 0.9. This study indicates a tetrahedral configuration around the Li ion, confirming the recent X-ray and p.m.r, results.

Invariant magneto-electric coefficients and invariant piezomagnetic coefficients are obtained for all the magnetic crystal classes.

Venäjän politiikka ja perustuslaki : Tutkimus Venäjän perustuslakikäsitteistön kehityksestä 1900-luvulla

Constitutional politics in Russia, a conceptual history study of the constitutional rhetoric in the 20th century In April 2006 the Russian Constitution had its 100th anniversary. Following its late start, five constitutions have been adopted. The great number of constitutions is partly explained in my work by the fact that Russia s political system has changed many times, from one state system to another. From a monarchical state power, it changed first, with the October revolution, into the Russian Socialist Federal Soviet Republic, and after that, in 1924, into the Union of Soviet Socialist Republics. In 1991, the Russian Federation was established. The great number of constitutions can also be explained by the fact that in a one-party system, constitutional concepts became one of the most important instruments for introducing political programmes. When the political unity of the state was not only restricted by the Constitution, but also by the party ideology, the political debates concerning constitutional concepts were the key discussions for all the reformative pursuits of Soviet politics. It can be said that, in the Soviet Union, almost all political discourses dealt with constitutional concepts. In the context of restricted unity, the constitutional concepts were the most important tools to argue and create a basis for a new presentation and new political programmes. Thus, the basic feature of the Soviet political discourses has been a continuous competition regarding the constitutional concepts. By defining the constitutional concepts, a new, the political elites wanted especially to redefine, their own way, the traditional meanings of the October 1917 Revolution, and to differentiate them from those of the preceding period of power. From a methodological point of view, I argue that the Russian constitutional concepts make a conceptual historical approach very suitable, and change the focus on history. This approach studies history in contemporary contexts which follow after each other, and whose texts are the main research target. The picture of history is created through the interpretation of the original sources of contemporary contexts. Focusing on the dynamic and traditional characteristic of Russian constitutional concepts, I refer to a certain kind of value and the task of these concepts to justify and define the political and societal unity in every situation. This is done by combining the pursued future orientation of constitutional unity with the new acts of preservation of the traditional principles of the revolution. The different time layers of the constitutional concepts, the past, the present and the future, are the key aspects of storytelling in justifying the continuity and redefining the constitutional unity for the sake of reform. These aspects of constitutional concepts, in addition to all the other functions, have been the main elements of the argumentative structure of acting against opponents.

Puukaupan säännöt : Yksityismetsänomistajien ja metsäteollisuuden puukauppa Itä-Suomessa 1919 - 1939

The Finnish forest industry bought more than half of the timber used in factories and sawmills in the 1930s from non-industrial private forests (NIPF). This research investigates the rules conformed to this timber trade. The main research questions are: what were the rules that influenced the timber trade; and by whom they were set up? Attention is also paid to the factors which advanced the forest owners’ negotiation possibilities. A variety of sources were used: legal and company statutes, timber trade contracts, archives of the forest companies and organisations. Moreover, the written reminiscences collected by the Finnish Literature Society in the early 1970s were used to analyse the views of individual sellers and buyers. An institutional economics approach was applied as the theoretical framework of this study. In the timber trade the seller (forest owner) and the buyer (the employee of the forest company) agreed to the rules of the timber trade. They agreed about the amount and the price of the timber on sale, but also rules concerning, e.g., timber marking and harvesting. The forest companies had a strong control over the written contracts. Neither the private forest owners nor the forest organisations had much influence over these contracts. However, they managed to influence the rules which could not be found in the contracts. These written and unwritten rules regulated, for instance, the timber marking and measurement. The forest organisations such as Central Forestry Board Tapio (Keskusmetsäseura Tapio) and associations of forest owners (metsänhoitoyhdistykset) helped private forest owners in gaining more control over the timber marking. In timber marking, the forest owner selected trees to be included in the timber trade and gained more information, which he could use in the negotiations. The other rule, which was changed despite forest companies’ resistance, was the timber measurement. The Central Union of Agricultural Producers (MTK) negotiated with the Central Association of Finnish Woodworking Industries (SPKL) about changing the rules of the measurement practices. Even though SPKL did not support any changes, the new timber measurement law was accepted in the year 1938. The new law also created a supervisory authority to solve possible disagreements. Despite this the forest companies were still in charge of the measurement process in most cases. The private forest owners attained changes in the rules of the timber trade mainly during the 1930s. Earlier the relative weakness of the private forest organisations had diminished their negotiation positions. This changed in the 1930s as the private forest owners and their organisations became more active. At the same time the forest industry experienced a shortage of timber, especially pulp wood, and this provided the private forest owners with more leverage.

Mapping the common antigenic determinants in avidin and streptavidin

An epitope scan analysis of the whole sequence of avidin and core streptavidin using polyclonal antibodies to these two antigens reveal the presence of multiple common epitopes in both the proteins. These antigenic determinants consist mostly of either identical or similar residues. The antibody recognition sites in both antigens are shown to be localized to homologous regions.
