- Abstract:
- ... Clay-cellulose biocomposite (CCB) was synthesized in the present study. Spin and pressure-induced heating was applied to aggregate exfoliated clay tubules and cellulose using polyethylene glycol as an intermediate. The synthesized CCB was modified in the presence of NaOH at high temperature to obtain negative surface charge on the adsorbent. Physico-chemical properties of CCB were evaluated using ...

- Abstract:
- ... Several isolates of an unknown oomycete resembling the genus Aphanomyces were obtained into laboratory culture from samples of noble crayfish (Astacus astacus) in 2016–2017. The crayfish were kept in cages in connection with a study on an eventually persistent crayfish plague infection in a small Finnish lake, following an acute episode of the disease in 2010. Despite the close resemblance of the ...

The aim of this work is (i) to review the recent studies on weather and climate change in Finnish Sápmi and to present the literature review findings alongside our survey on the observations made by local reindeer herders on the same phenomena, and, further, (ii) to review the impacts of climate change on the ecosystem services (ES) in Finnish Sápmi. The focus of the study is on the impacts of cli ...

One can let several samples represent the same population over larger areas, or alternatively model the dynamics of each sampling location in continuous space. We analysed the spatio-temporal population dynamics of six phytoplankton taxa in the Baltic Sea applying multi ...

- Abstract:
- ... The phytopathogen Phytophthora cactorum infects economically important herbaceous and woody plant species. P. cactorum isolates differ in host specificity; for example, strawberry crown rot is often caused by a specialized pathotype. Here we compared the transcriptomes of two P. cactorum isolates that differ in their virulence to garden strawberry (Pc407: high virulence; Pc440: low virulence). De ...

However, the levels of heavy metals in ants’ nests and explicit individual-level responses towards heavy metals have not been revealed. We found that red wood ants Formica lugubris accumulate high and correlated values of such heavy metals as Al, Cd, ...

This study presents two hypothetical challenges: (1) the actors in the Finnish food chain do not have a common community that would cover the entire food chain from primary producers to the consumers of organic food and that would, by communal effort, enhance the development of the organic food chain, and (2) a fairer share of power among the food chain actors would enable the development of the o ...

This article presents a newly developed model of the Finnish food chain and suggests changes to enable the government goals for organic food and its production to be reached, as well as to better answer consumer demands for organic food. The current food chain causes negative externalities and that creates the urgent need for remodelling the food chain activity. The approach is taken by proposing ...

Since fuel conversion is limited by mass and heat transfer and the rates of chemical reactions inside the particle, the optimal model would produce the internal conditions as a function of location. As rigorous 1D, 2D and 3D fuel conversion models presented in the l ...

One reason is that organic products do not meet the quality requirements of consumers, and another that consumers have been left out of food chain planning and decision-making for food selection.

The batch adsorption experiments showed that WDAS can adsorb 200 (±9.0) mg of uranium(VI) per g of WDAS. The maximum adsorption of uranium(VI) was achieved even at an acidic initial pH of 2.7 which increased to a pH of 4.0 in the equilibrium state. ...

Snow depths declined, and temperatures increased significantly ov ...
