The authors make a valiant effort at extracting additional information about the properties of aerosol from measurements with optical particle counters (OPC), in particular the PCASP and the FSSP-300. In the end, the results are convincing and they have done a very nice job of constraining the uncertainties. The style of writing, however, is at times obtuse and difficult to understand. Examples...

Wafer-level packaging (WLP) is a next-generation semiconductor packaging technology that is important for realizing high-performance and ultra-thin semiconductor devices. However, the molding process, which is a part of the WLP process, has various problems such as a high defect rate and low predictability. Among the various defect factors, the die shift primarily determines the quality of the ...

this article is an overview of materials used for paper sizing to improve its packaging characteristics. sizing is an important way of cellulose fibers’ modification as a mean to increase its resistance to absorption or penetration of fluids, especially water. from the functional viewpoint, this definition is equal to reinforcement through application of chemicals on paper or cardboard’s surfac...

packaging is one of the most effective marketing instruments in selling most of the products, in particular the consuming products. due to the fact that most purchases particularly in department and chain stores are performed randomly and without a previous programming, packaging has a key role in attracting buyers and their selling products. a package with a charming and elegant design can be ...

The role of plastics and paper as food packaging materials is reviewed with a brief outlook on the historical background of food packages in general. The inherent properties of these food packages that should be considered by food processors are also discussed. The current efforts in meeting the needs of consumers in ensuring food’s quality with prolonged shelf life during storage and distribut...

A 120-base pRNA encoded by bacteriophage b29 has a novel and essential role in genomic DNA packaging. Six DNA-packaging RNAs (pRNAs) were bound to the sixfold symmetrical portal vertex of procapsids during the DNA translocation process and left the procapsid after the DNA-packaging reaction was completed, suggesting that the pRNA participated in the translocation of genomic DNA into procapsids....

Nonylphenols (NP) possess estrogenic activities and may cause increased risk of cancerous and reproductive abnormalities in several living organisms. Despite their harmful nature, NPs are used as additives in food packaging material, especially plastic, which is the main food contact material in today's packaging landscape. According to the fact that food packaging is one of the major potential...

Technical advances in RF and GaAs devices have generally outpaced those in device packaging. This disparity has created a situation where packaging technology can become a limiter to device performance. A process strategy is presented here for massively parallel creation of hermetic wafer scale packaging for RF devices.

in this study, shelf life properties of tomato powder under effect of air drying temperature were studied. the qualitative determination was observed that acceptance of color, aroma,flavor, and appearance at 70oc is better, so best temperature was 70oc for producing of tomato powder. tomato powder after drying ,were stored into three kind of packaging including thin cellophane, thick cellophane...
