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.

2. Projekt støttet af Kulturministeriets Forskningspulje:
Rituelt måltid eller hverdagskost? Nye naturvidenskabelige analyser
af Tollundmandens mave-tarmindhold
6. (Årbøger 1951)
Helbæks konklusioner vedr. Tollundmandens
sidste måltid (Helbæk 1951; 1959):
• Spist 12-24 timer inden sin død
• Grød af korn og frø fra 20 forskellige
plantearter
• Ingen spor af kød
+ æg fra piskeorm
7. Ny undersøgelse
Opnå indsigt i:
• Et moseligs sidste måltid
• Kvantificere planteingredienserne
• Lede efter hidtil uregistrerede ingredienser
• Undersøge tilstedeværelsen af ukrudtsfrø/tærskeaffald
• Håndtering og tilberedning af fødevarer
• Helbred og sanitære forhold i jernalderen
8. Metoder
Analyse af:
• Makrofossiler
• Pollen
• NPP’er
• Lipider
• Proteiner

16. Tollundmandens sidste måltid
Byggrød tilsat lidt frø fra bleg
pileurt og hør – og fisk
Korn OG frø var gruttet inden
tilberedningen
Var det et almindeligt måltid??
