J. J. Carlberg. (1935). Bestämning av pH-värdet i utspädda bikarbonatlösningar vid olika CO2-tryck. Acta Forestalia Fennica vol. 42 no. 3 article id 7320. https://doi.org/10.14214/aff.7320
English title: Analysis of pH in diluted bicarbonate solutions using different partial pressures of CO2.

The paper is a dissertation paper that describes analysis of pH in diluted bicarbonate solutions using different partial pressures of CO2. In the work, an equation was obtained from the balance equations of a base-bicarbonate-water system. Similarly, an equation was obtained to describe the relationship of partial pressure of CO2 and hydrogen ion concentration of a bicarbonate solution. This equation can be used to determine the bicarbonate concentration of a gas mixture.

The PDF includes a Finnish and German summary.

J. P. Norrlin. (1923). Lectio praecursoria, gehalten von J. P. Norrlin bei seiner Disputation am 13. Mai 1871. Acta Forestalia Fennica vol. 23 no. 2 article id 7101. https://doi.org/10.14214/aff.7101
English title: Lectio praecursoria (the opening presentation) of J. P. Norrlin at his public defence of a doctoral thesis on may 13th 1871.

The text is the opening presentation by the author at his public defence of his doctoral thesis on plant geography of Finland. The text discusses the principles that apply on plant geographical classification of earth with respect to characteristics of vegetation and gives an oversight on the plant geographical work conducted in Scandinavia.

English title: Academic dissertations and doctors in forestry sciences in Finland.

The study analyses Finnish academic dissertations in forestry sciences on the basis of number published and yearly trends, length, topic, sources of funding and guidance, and the doctoral candidates’ background and career development before and after disputation.

From 1912–1984, 131 dissertations in forest sciences were published. The majority of them were written in Finnish. The length averaged 151 pages. In general, the more rapidly the dissertation was prepared, the better grade it received.

The majority of doctors in forest sciences come from well-to-do families, in cities located in Southern Finland. They constitute 2–6% of the total number of graduating foresters. At the time of disputation their average age has been 36 years. Doctors have used job changes to improve their position in the hierarchy of their employing institutions.

The PDF includes a summary in English.
