This document discusses the degradation of plastics over time. It examines research on the breakdown of various plastic materials, such as polyethylene bottles and polystyrene cups, when exposed to different environmental conditions like weather, sediment, and heat over periods of 2 years. The research found that plastic type and environment significantly impact degradation rates, with thermal aging causing faster breakdown than weather or water exposure. Most plastics showed chemical changes within 24 months, with polyurethane breaking down most quickly. Cigarette butts were also examined and found to degrade into paper and acetic acid. Understanding plastic degradation can help address the global pollution problem.

This document discusses sustainable transport and packaging materials for artworks. It summarizes the risks involved in transporting cultural heritage like vibration, climate changes, theft and accidents. It outlines preventative measures like planning, confidentiality, gloves, experienced handlers, adequate packaging, labeling, fastening, couriers, supervision and equipment to control temperature and humidity. It also notes the dilemma between requirements for transporting art versus sustainable solutions. Different transport methods like trucks, planes, ships and trains are discussed in terms of sustainability. Finally, it provides examples of sustainable packaging and transport approaches like reusable crates, flexible packaging systems and virtual couriering.
1. The document provides guidance on practicing integrated pest management (IPM) in a calm and reasonable manner. It advises focusing IPM efforts on key areas like sanitation, exclusion of pests, and monitoring, rather than trying to inspect and treat everything.
2. Effective monitoring of pest populations involves using traps, record keeping, and identifying problem areas. Traps should be placed strategically and checked regularly.
3. Proper inspection is the foundation of any IPM program. Inspections should be routine and involve looking for pests, signs of pests, and conditions that could attract pests. Focus inspection on vulnerable areas and artifacts.
Art Barns Lolland is a new museum that will exhibit large-scale contemporary art installations across historic cultural sites on the Danish islands of Lolland-Falster. Visitors will experience over 250 years of cultural history and outstanding 21st century artworks through journeys across the islands. The museum aims to connect modern art with the islands' impressive architectural heritage.

22. (Jomsvikingernes Saga):
‘Knud opfostrede Sigurd Orm i Øjes søn og gav ham sit
eget navn og kaldte ham Hardeknud. Og Hardeknuds
søn var Gorm, der blev kaldt Gorm den Gamle eller
den mægtige’
SAXO: Hans søn Gorm, som fik tilnavnet den engelske
fordi han var født i England, besteg kongetronen der
på øen efter faderens død. ..for da han tog over fra
England til Dannmark for at ordne forholdene der,
kom et kort fravær til at betyde et langvarigt
tab…sådan greb han grådigt magten i to riger; men i
samme øjeblik han sikrede sig det ene, mistede han
uigenkaldeligt det andet, og han gjorde aldrig noget
alvorligt forsøg på at vinde det tilbage.
Var Gorm

Thyra?
23. Konkluderende
• Det sydjyske område har fra Kristi Fødsel været et magtmæssigt,
markant område, krigsmæssigt og kultmæssigt. Det nye fund fra
Vindelev fra 500-tallet underbygger dette i et langt tidsperspektiv.
• I yngre jernalder og vikingetid konsolideres det stærke, jyske islet.
• I 6-800-tallet ser vi kongelige haller (ved Erritsø), der peger på tætte
kontakter mod det sjællandske område, og stedet indgår angiveligt i
en del af Danmark (rejsekongedømme?)
• Fra 875-900-tallet – ser vi måske mere (syd)jysk autonomi. I 900-tallet
dukker Thyra op som en vigtig person, der er den der (ved giftemål)
hjælper det nye dynasti med Gorm i spidsen i Jelling til magten
