One of the main challenges facing the electronics manufacturing industry in solder paste printing for ultra-fine pitch surface mount and flip-chip assembly is the difficulty in achieving consistent paste deposit volumes from pad-to-pad. At the very small aperture geometries required for ultra-fine pitch and flip chip assembly, flow properties of the paste becomes one of the dominant factors in ...

Three kinds of taro paste were prepared with taro:water:sugar ratios of 1:0.33:1.4, 1:0.33:0.8 and 1:0.33:0.2. Results indicated that the paste with the highest sucrose concentration had the least hard texture. The retarding effect of sugar on hardness development and water mobility of the low concentration system was fructose > glucose > lactose > sucrose. The DSC characteristics showed that a...

This study aimed to evaluate by the intra-osseous implant technique the most commonly used materials for pulp therapy in pediatric dentistry: calcium hydroxide (CH), Guedes Pinto paste and CTZ paste, according to FDI (1980) and ANSI/ADA (1982) recommendations. Thirty guinea pigs, 10 for each material, divided into experimental periods of 4 and 12 weeks received one implant on each side of the l...

This study is a model of artificial perceptron neural network including three inputs to predict the Nusselt number and energy consumption in processing tomato paste shell-and-tube heat exchanger with aluminum oxide nanofluid. The Reynolds range 150–350, temperature 70–90 K, nanoparticle concentration 2–4% were selected as input variables, while corresponding considered target. has 3 inputs, 1 h...

BACKGROUND Copy and paste functionality can support efficiency during clinical documentation, but may promote inaccurate documentation with risks for patient safety. The Partnership for Health IT Patient Safety was formed to gather data, conduct analysis, educate, and disseminate safe practices for safer care using health information technology (IT). OBJECTIVE To characterize copy and paste e...

The copy-paste command is a fundamental and widely used operation in daily computing. It is generally regarded as a simple task but the process can become tedious when frequent window switching is required to copy-paste across different documents. Autocompletion is another popular operation aimed at reducing users’ typing effort. It contrasts to copy-paste by allowing for text completion withou...

Nano-TiO2 (NT) and nano-SiO2 (NS) were separately added in the cement paste to investigate the rheological property of fresh mixtures and mechanical strength in hardened state. The effects of different dosages and types of nano-particles on the properties of cement paste were studied. The results indicated that the rheological behavior of the fresh cement paste coincides with the Modified Bingh...
