Water Resources management in Zambia and Zimbabwe. Report from study trip 1992

Two researchers, Mr. Hans Olav Ibrekk and Mr. Jan Sørensen from Norwegian Institute for Water Research (NIVA), visited Zambia and Zimbabwe for two weeks in April/May 1992 to undertake a comparative study on water resources management. The study was financed by the Norwegian Ministry of Foreign Affairs and the Norwegian Institute for Water Research as part of a program to improve Norwegian environmental scientist's competence with regard to development aid co-operation. The report is divided in the three main, 2)Zambia and 3)Zimbabwe. Part two, on Zambia also contains a list of concrete project ideas/proposals for planned R & D co-operation between the Zambian National Council for Scientific Research (NCSR) and the Norwegian Institute for Water Research (NIVA)/State Pollution Control Authority (SPCA).Norwegian Ministry of Foreign Affair

Vannbruksplanlegging. Status og erfaringer

Målet med evalueringen var å identifisere forhold som kan forklare hva som bidrar til å styrke vs. svekke vannbruksplanene som styringsredskap slik at senere planarbeider kan dra nytte av disse erfaringene. For å evaluere de utførte vannbruksplanene i Norge ble det sendt ut et spørreskjema til alle vassdragsforvalterne i miljøvernavdelingene. Siden slutten av 70-tallet er det utført ca. 65 vannbruksplaner i Norge. Planenes mulighet til å styre utviklingen i nedbørfeltet avhenger i stor grad av koblingen til det ordinære plansystemet i henhold til Plan- og bygningsloven. Et kritisk punkt er organiseringen av planarbeidet. Svak organisering synes å være den viktigste årsaken til manglende oppfølging og gjennomføring.Miljøverndepartementet (MD

Comparison between theoretically and experimentally determined electronic properties:applications to two-photon singlet oxygen sensitizers

A series of oligo-phenylenevinylenes are investigated by spectroscopic measurements and calculations with the aim to rationalize the correlation between the electronic structure of the molecules and their efficiency as two-photon singlet oxygen sensitizers. The band-shape functions of selected two-photon absorption processes are analyzed and the corresponding spectra are deconvoluted. This analysis allows for a comparison between calculated and measured two-photon absorption cross sections where a reasonable agreement is found
