Sammendrag

Lecture at the DRIMON (www.drimon.no) Student Course in Durres, Albania, 14-18 September 2009. The lecture included overview of concepts related to IWRM, the EU Water Framework Directive, transboundary waters, and related issues.

Forsøk med oppfôring av kopplam etter to ulike strategier viser at produksjon av kopplam med bruk av melkeerstatning og kraftfôr generelt er lite lønnsomt. Det er beregnet et forventet "overskudd" per kopplam på bakgrunn av utgifter til melkeerstatning og kraftfôr de første syv ukene (tabell 1) og utgiftene til kraftfôr i beiteperioden fram til slakt. "Overskuddet" er beregnet til ca 173 kr og 53 kr hhv i 2007 og 2008. Det er i beregningene ikke tatt hensyn til alle utgifter som vaksiner, smokker, flasker, strø og arbeid. Det kan være aktuelt å se på andre former for framfôring som for eksempel en mer moderat tildeling av kraftfôr i beiteperioden (400-500 g per dyr per dag) og eventuelt bruk av annen type beite enn vanlig eng. Mer forskning må til før det er mulig å konkludere med lønnsomheten i norsk kopplamproduksjon.

28 oksekalver av rasen Hereford inngikk i et forsøk med intensiv oppfôring for slakting i en alder av ca 12 måneder i to forsøksledd. Det ble ikke funnet noen forskjeller i produksjonsresultater på kalvene i de to gruppene, men det ble funnet et merforbruk av kraftfôr for den ene gruppen. Det ble konkludert med at intensiv oppfôring av Hereford kalver til slakting når de er ca 1 år gamle er mulig.

This paper examines the relationship between external relations and innovation in small, knowledge-intensive Norwegian firms. Our findings indicate that external relations are beneficial for innovation. The analysis shows that it is necessary to treat innovation as more than a concept. Our independent variables related differently to product innovation, process innovation, and market innovation. We found that market participation in product development has a positive impact on product, process and market innovation. We also found that top management interaction with other firms had a positive effect on market innovation and that top management interaction with external R&D had a positive effect on product innovation. This finding probably indicates that access to R&D resources is vital for product development in the context of knowledge-intensive products. The results also show that participation in conferences and courses positively influences process and market innovation and that systematic environmental scanning positively influences product innovation.

The effects of timing of nitrogen (N) fertilization relative to the beginning of a 4-week floral-inducing short-clay (SD) period have been studied in 'Korona' strawberry plants under controlled environment conditions. Groups Of low fertility plants were fertilized with 100 ml of calcium nitrate solution for 3 days a week for a period of 3 weeks starting at various times before and at the beginning of the SD period, as well as at different times during the SD period. All plants, including SD and long day (LD) control plants, received a weekly fertilization with a low concentration complete fertilizer Solution throughout the experiment. Leaf at-ea. fresh and dry matter increments of leaves, crowns and roots, as well as leaf chlorophyll concentration (SPAD Values) were monitored during the experimental period. A general enhancement of growth took place at all times of N fertilization. This was paralleled by an increase in leaf chlorophyll concentration, indicating that the control plants were in a mild state of N deficiency. When N fertilization was started 2 weeks before beginning of the SD period, flowering was delayed by 7 days, and this was gradually changed to an advancement of 8 days when the same treatment was started 3 weeks after the first SD. The amount of flowering was generally increased by N fertilization although the effect varied greatly with the time of N application. The greatest flowering enhancement Occurred when N fertilization started I week after the first SD when the number of flowering crowns and the number of inflorescences per plant were more than doubled compared with the SD control, while fertilization 2 weeks before SD had no significant effect on these parameters. Importantly, the total number of crowns per plant was not affected by N fertilization at any time, indicating that enhancement of flowering was not due to an increase in potential inflorescence sites. No flowering took place in the control plants in LD. Possible physiological mechanisms involved and practical applications of the findings are discussed. (C) 2009 Elsevier B.V. All rights reserved.
