Observation of manganese nodules and encrustations in various lakes of Finland

The limnic ferromanganese ore concretions in some Finnish lakes are described. Their chemical and mineral compositions have been measured as have their natural surroundings - the latter by means of physico-chemical in-situ analysis. The sources of the nodules' contents are discussed, and a theory based on the calculated precipitation fields of the important ore minerals is presented for the ore formation.

(Tables, page 17-18), Chemical composition of ferromanganese concretions of the lakes of Northern Savolax in Eastern Finland

This paper discusses the occurrence of manganese-rich concretions in the lakes of Northern Savolax in Eastern Finland. The samples were collected in the summer of 1905 and left to dry for 2 months at room temperature. The quantity of H2O mentionned in the analysis was obtained by dessication at 155°C. The amount of Mn is calulated as MnO2 although other valences might be present in the samples. The contents in CO2 and organic substances was not determined. J. Aschan determined that as a general rule, in Finland the manganese rich lake deposits are rather associated with soft bottom sediments while the iron rich deposits are more assocaited with hard or sandy bottoms.

Average chemical composition of lake ores of Finland and North-Eastern Russia extracted in the late nineteen century

According to Solitander C. P., the extraction of lake ore from Eastern Finland lakes considerably rose in the 1870 - 1880 period in relation with the increasing demand from the ironworks being operated in the region. In St. Petersburg, Nicholas Putiloff, a business tycoon and State Minister owned the Haapakosken, Huutokosken and Oravin ironworks which were using 99% of lake ore for their supply. During this period the biggest production came from lake Sysmäjärvi in the Joroinen county with 3676 tonnes at an average concentration of 35.94% Fe, 4.55% Mn, 0.26% P and 0.04% S. The Värtsilä ironworks used the lake ore coming from 49 lakes, the biggest production coming from lake Loitimojärvi with 14535 tonnes of ore with a medium at concentration of 30.8% Fe. Möhkö ironworks took advantage of the 59 lakes, the largest of which was from lake Koitere with 4301 tonnes at 41.3% Fe. The Karttula ironworks were also significant in the consumption of ferromanganese lake ore.

Loadings of dissolved organic matter and nutrients from the Neva River into the Gulf of Finland – Biogeochemical composition and spatial distribution within the salinity gradient

We studied the loadings of dissolved organic matter (DOM) and nutrients from the Neva River into the Eastern Gulf of Finland, as well as their distribution within the salinity gradient. Concentrations of dissolved organic carbon (DOC) ranged from 390 to 840 μM, and were related to absorption of colored DOM (CDOM) at 350 nm, aCDOM(350), ranging from 2.70 to 17.8 m-1. With increasing salinity both DOC and aCDOM decreased, whereas the slope of aCDOM spectra, SCDOM(300-700), ranging from 14.3 to 21.2 μm-1, increased with salinity.

The Influence of Informational and Emotional Advertising Appeals on Advertising Effectiveness – Consumers’ Perspective on the Over-the-Counter Product Advertisements in Finland

Consumers face enormous amounts of promotional messages daily whereas the pharmaceutical companies among other industries spend considerable time and money developing effective advertising strategies. There are multiple possible ways to appeal the target customer in order to increase the effectiveness of the advertisement. In spite of the various possibilities to categorize persuasive communication, the informational and the emotional appeals are the typical approaches. This study assesses the influence of the informational and emotional advertising appeals on the advertising effectiveness in the context of OTCs in Finland. The research method applied in this study is a quantitative survey. The data consists of 461 responses from the target population of 18–80 years old Finnish speaking consumers. The results from the marketing research indicate that the positive correlations of the emotional appeals are much stronger than the positive correlations of the informational appeals relating to the advertising effectiveness. However, on average the Finnish consumers experience the OTC advertisements relying on the informational appeals more effective than the OTC advertisements relying on the emotional appeals. Furthermore, within emotional appeals there is a much greater variety in the experienced advertising effectiveness not providing as stabile and consistent experienced advertising effectiveness compared to the informational appeals. Thus, the OTC advertisement relying more on the emotional appeals are much more risky in terms of advertising effectiveness. There are also differences with the experienced advertising effectiveness between the Finnish consumer groups and the information can be utilised when designing tailored OTC advertisements. The Finnish men consider humorous advertisements more effective than the Finnish women. In addition, the people living outside Uusimaa Region experience higher advertising effectiveness with the advertisements relying more on the informational advertisements compared to the people living in Uusimaa Region. In similar vein, the people with lower education experience higher advertising effectiveness with the advertisements relying more on the informational advertisements compared to the people with high education. Additionally, the older generation perceive an OTC advertisement with a middle-aged celebrity more effective than the younger consumers
