Formaldehyde as Screen Printing Indoor Pollutant
The presence of formaldehyde in indoor air samples has been detected in five screen printing facilities of Novi Sad, Serbia. Air was sampled five times during one working week for each screen printing facility. The sampling was conducted continuously during 4 hours. The concentrations of formaldehyde were determined by UV-VIS spectrometry at 580 nm. The average concentrations of formaldehyde we...
متن کاملInfluence of Substrate and Screen Thread Count on Reproduction of Image Elements in Screen Printing Authors
The printing plate and its characteristics in the conventional printing techniques have a significant impact on print quality and image appearance. In screen printing, a weave of screen mesh i.e. a number of threads per cm, is the most important characteristic of the printing plate, hence the most relevant factor which defines printing quality. Print quality itself is a complex term that includ...
متن کاملSCREEN : Flat Syntactic and Semantic Spoken Language
Previous approaches of analyzing spontaneously spoken language often have been based on encoding syntactic and semantic knowledge manually and symbolically. While there has been some progress using statistical or connectionist language models, many current spoken-language systems still use a relatively brittle, hand-coded symbolic grammar or symbolic semantic component. In contrast, we describe...
متن کاملScreen Printing Process Design of Experiments for Fine Line Printing of Thick Film Ceramic Substrates
Screen printing has been the dominant method of thick film deposition because of its low cost. Many experiments in industry have been done and many models of the printing process have been developed since the 1960’s. With a growing need for denser packaging and a drive for higher pin count, screen printing has been refined to yield high resolution prints. However, fine line printing is still co...
متن کاملScreen-Printing Fabrication and Characterization of Stretchable Electronics
This article focuses on the fabrication and characterization of stretchable interconnects for wearable electronics applications. Interconnects were screen-printed with a stretchable silver-polymer composite ink on 50-μm thick thermoplastic polyurethane. The initial sheet resistances of the manufactured interconnects were an average of 36.2 mΩ/◽, and half the manufactured samples withstood singl...
