Konferensbidrag (refereegranskat)abstract
- This is an EU-funded project related to cross boarder collaboration for educational purposes supported by information and communication technologies between Danish, Norwegian and Swedish schools. The project started in 2011 and extends to 2014 so this empirically dominated paper reports on early findings related to cross-border collaboration challenges. The aim of the project is to develop innovative cross-border teaching models by the means of user-driven, practice-based co-design processes between practitioners and researchers. In the first year, 18 classes from 13 schools in Denmark, Norway and Sweden in the Öresund-Kattegatt-Skagerack region participated. Organized in so called Nordic class-match groups (consisting of students and teachers from one class in each country) new cross-border teaching models are co-created, tested and evaluated in an iterative process. Since teaching models are subject dependent, the project develop teaching models in several subject domains, i.e. math, language, science and social studies / history. Heretofore findings show, however, that organizational and technical issues have superseded and squeezed out subject-oriented discussions due to surprisingly many practical issues that needed to be handled first. We have identified three major thresholds to overcome. The first is related to technical difficulties in schools when diverse IT systems are to be synchronized. The second threshold concerns scheduling coordination difficulties in order to allow synchronous cross boarder collaboration. The third threshold concerns linguistic and communication difficulties rooted in participants communicating in their respective Nordic language. Being able to communicate within Nordic languages are explicit learning goals in all three schools systems, and therefore part of the project aim and consequently all participants are expected to use their native languages when communicating. The next phase of the project is therefore to find solutions to these technical, organizational and linguistic barriers, and already now we see some barrier breaking models taking shape in the active network of Nordic teachers, students, school leaders, IT support teams and researchers.

Phosphorus efficiency of potato varieties differing in maturity type
- 2013
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The objective of the present work was to investigate the effect of phosphorus fertilization on yield and phosphorus uptake and to compare the phosphorus efficiency for six potato varieties. During 2011 and 2012, field experiments were conducted on soils containing low levels of available phosphorus. Phosphorus fertilizer was added in the amounts of 0, 30 and 60 kg phosphorus per ha. In 2011, soil heterogeneity was large and tuber yield was increased by phosphorus addition only as a mean over all varieties. In 2012, an improved tuber yield by phosphorus fertilization was observed for most varieties. The weight of the larger tuber fractions was generally increased by phosphorus fertilization. Phosphorus efficiency, calculated as tuber dry weight per unit of fertilizer phosphorus added, tended to be higher for late than for early or intermediate varieties. The results indicate that late varieties might be more suitable than earlier varieties for locations were the risk of nutrient losses is high.

Konferensbidrag (refereegranskat)abstract
- Callus from seven different elite embryogenic cell lines of Norway spruce originated from the controlled crossing conducted by Skogforsk (Forest Research Institute of Sweden) have been cryopreserved in liquid nitrogen using the slow freezing method with sorbitol (0.2 and 0.4 M) and DMSO (5% v/v) as cryoprotectants. Cooloing of samples was performed in a programmable freezer Cryo Med 7452. The cryovials were inserted at +4 degrees C and frozen at -0.3 degrees C/min to -16 degrees C. After 15 min at -16 degrees C, to avoid rapid cooling and crystal formation in the cells, the cryovials were further cooled to -35 degrees C at -0.3 degrees C/min. At the end of the freezing program the cryovials were transferred and stored in a CBS V1500 liquid nitrogen storage unit at -196 degrees C. After thawing and plating on proliferation medium, the recovered cells showed a short lag phase, after which they continued to grow. Lags in growth were also observed after the transfer to pre-maturation and maturation media. Somatic embryo maturation and plantlet regeneration occurred in all the tested embryogenic lines.
