Preservative Approach to Study Encased Archaeological Artefacts

We propose a workflow based on a combination of computed tomography, 3D images and 3D printing to analyse different archaeological material dating from the Iron Age, a weight axis, a helical piece, and a fibula. This workflow enables a preservative analysis of the artefacts that are unreachable because encased either in stone, corrosion or ashes. Computed tomography images together with 3D prin...

Denim Sandblasting and Silicosis: Two Case Reports

Background: Silicosis is one of the oldest recorded occupational lung diseases, known since the time of Hippocrates and the ancient Egypt. It is an untreatable illness characterised by irreversible and progressive fibrotic reaction in the lung tissue caused by inhaling silica dust crystals with aereodynamic diameters of 0.5-5.0 micron diameter. It is a significant cause of mortality in the deve...

Behavior of Castellated I Beams Encased in Concrete

Five methods are introduced for design of castellated I beams encased in concrete. One of the methods, plastic analysis, is thoroughly explained and the relevant equations are developed. Eight castellated I beams encased in concrete are made and tested. The theoretical design methods are all compared with the test results and the safety factor for each method is calculated. The results show tha...

Pneumothorax in the cases with silicosis due to denim sandblasting

Amaç: Bu çalışmada kot taşlama işine bağlı silikozisin akut ve hızlandırılmış formlarında seyreden sekonder spontan pnömotoraks olguları bildirildi. Ça­lış­ma­ pla­nı:­Çalışmaya son beş yıl içerisinde taşlanmış kot pantolonu üreten küçük işyerlerinde çalışan ve silikozise bağlı sekonder spontan pnömotoraks gelişen yedi erkek hasta (ort. yaş 20.4 yıl; dağılım 17-23 yıl) dahil edildi. Pnömotoraks...
