This document discusses several electrocardiogram (ECG) findings:
1. A right bundle branch block with left axis deviation can indicate bifascicular block. T wave inversions in V1-V3 can be due to right bundle branch block or previous anterior wall myocardial infarction.
2. Brugada Syndrome Type 2.
3. Very rapid atrial fibrillation with a wide QRS indicates Wolff-Parkinson-White syndrome due to an accessory pathway with aberrant conduction.
This document describes a presentation given by imacat (Yang Shih-Ching) about creating mosaic art and stop-motion animations using spreadsheets in OpenOffice Calc. The presentation demonstrates creating a mosaic version of the iPod advertisement using 256 frames and calculating average colors with Java. It also discusses an approach by Villeroy that stores color values in cells and paints them faster using OpenOffice BASIC macros. The presentation concludes by demonstrating a full mosaic version of the Gangnam Style music video created over 10 spreadsheet documents and concatenated into one video.
1. The top 3 animals that kill the most humans are mosquitoes, people, and tsetse flies. Mosquitoes kill approximately 1 million people per year by transmitting diseases like malaria. People themselves prove to be the best at killing other humans on a daily basis. Tsetse flies spread African sleeping sickness, affecting 500,000 people and killing 80% of those infected.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help boost feelings of calmness, happiness and focus.

St. Philomena is a young virgin and martyr whose tomb was discovered in the ancient catacombs of St. Priscilla in Rome in 1802. She is credited with countless miracles and intercessions since. According to her story revealed to three people, she was martyred at age 13 after refusing to marry Emperor Diocletian and remaining faithful to her vow of virginity to Jesus Christ. Despite many tortures, she survived through divine intervention. She was eventually beheaded and attained glory in heaven. Her devotion has spread rapidly around the world in modern times.

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.

5. Hvorfor
• Fordi Tetraethylsilikaters effektivitet og potentiale til stabilisering af
sedimenter ikke hidtil er blevet undersøgt systematisk på baggrund af
forsøg med forskellige sedimenttyper med kendt sammensætning.
• For at skabe et bedre grundlag for udarbejdelse af praktiske
konserveringsforslag til stabilisering af arkæologiske sedimenter og
præparater, hvor essentielle aspekter, såsom antal af imprægneringer,
væskeforbrug, økonomi og tidsforbrug inddrages.
Fra et specifikt arkæologisk sediment til en bredere undersøgelse…

17. Specialets hovedkonklusioner (I)
TEOS & LER
• Ingen af de fire produkter var i stand til at imprægnere sedimenttypen ”Ler”
• Det var muligt at imprægnere sedimentblandinger med et vist lerindhold
(Harpet muld og Plantemuld, samt de lerede ”originale” arkæologiske sedimenter)
TEOS & SAND/GRUS/SEDIMENTBLANDINGER
• Dybtgående imprægnering var mulig med de tre TEOS – Syton X30 ikke velegnet!
• Resulterede i forøget sammenhængskraft/hårdhed/styrke
18. Specialets hovedkonklusioner (II)
TEOS & geldeponering (styrkeforøgelse)
• Mængden af den deponerede gel er afgørende for at opnå en effektiv
stabiliserende imprægnering af de porøse sedimenter.
• Da det er gelen, der fungerer som en udfyldende strukturel og ”cementerende”
binder.

19. VURDERING AF TEOS
Tetraethylsilikater har et stort potentiale til stabilisering af et bredt
udvalg af porøse sedimenter - og til strukturel stabilisering af
”originale” arkæologiske sedimenter og præparater.
20. Nye undersøgelser af TEOS & tyndslib
Med fokus på de modificerede TEOS-typer
Samarbejde med Knud Botfeldt og Jørn Bredal-Jørgensen, KADK
Tak til Konservatorskolens Forskningsudvalg for bevilling til tyndslibsanalyser
21. TEOS´s ”attraktive” egenskaber
Mange års erfaringer fra brug indenfor stenkonservering
Relativ lav viskositet og overfladespænding
God indtrængningsevne
God affinitet med silikat
Polymerisering til fast amorft hydreret siliciumdioxid; silica gel
Gelen deponeres tredimensionelt i den porøse struktur
Stenmaterialet opnår forøget ”hårdhed”/”styrke”
Stenmaterialets naturlige farvemætning og glans bibeholdes
Stenmaterialets diffusionsåbenhed bibeholdes
22. TEOS´s ”uattraktive” egenskaber
• De kommercielle TEOS-produkter er sundhedsskadelige og
lokalirriterende på væskeform.
• De kommercielle TEOS-produkter er yderst brandfarlige på
væskeform.
• Under ”afhærdningen” dannes der sundhedsskadelige
ethanoldampe.

23. TEOS´s grundlæggende præmis
• Konsolidering med TEOS er en irreversibel proces.
• Hænger uløseligt sammen med det egentlige formål;
At opnå en dybtgående og holdbar strukturel konsolidering
med god kemisk affinitet, som er forankret ensartet i det
porøse materiales tredimensionelle struktur.
