The difference in the heating penetration characteristics of product processed in retort by steam-air application and water immersion was studied. Fresh milkfish (Chanos chanos) packed in dry pack and in oil medium, both in flexible pouches, was thermal processed to minimum F0 value of 7.77 at 121.1°C. Heat penetration values were recorded for each minute of processing with the aid Ellab (TM 96...

Background: The stratum corneum (SC) forms a difficult physical barrier for drugs to pass through the skin. Several strategies were developed to overcome this barrier. Optimization of topical drug formulations by selected excipients may facilitate the penetration of drugs through the SC into the viable skin cells and ultimately into the systemic circulation. Methods: Here, both the influence of...

The ability of nanoparticles to penetrate the stratum corneum was the focus of several studies. Yet, there are controversial issues available for particle penetration due to different experimental setups. Meanwhile, there is little known about the mechanism and determinants of their penetration. In this paper the penetration of four model gold nanoparticles of diameter 6 and 15 nm, differing in...

Cooperative ITS is enabling vehicles to communicate with the infrastructure to provide improvements in traffic control. A promising approach consists in anticipating the road profile and the upcoming dynamic events like traffic lights. This topic has been addressed in the French public project Co-Drive through functions developed by Valeo named Green Light Optimal Speed Advisor (GLOSA). The sys...

We estimate the effect of Internet on volume of trade in a major distributed marketplace. From 1997 to 2007, a period during which residential Internet use tripled, Internet increased the volume of used cars traded in California by 7.2 percent. This implies a substantial welfare gain due to reductions in market frictions of approximately $43 million per year relative to 1997 Internet penetratio...

According to literature, penetration pricing is the dominant pricing strategy for network effect markets. In this paper we show that diffusion of products in a network effect market does not only vary with the set of pricing strategies chosen by competing vendors but also strongly depends on the topological structure of the customers' network. This stresses the inappropriateness of classical "i...

Much of recent Trade theory focuses on heterogeneity of firms and the differential impact trade policy might have on firms with different levels of productivity. A common problem is that most firm level dataset do not contain information on output prices of firms which makes it difficult to distinguish between productivity differences and differences in market power between firms. This paper de...

Data on macroscopic superconducting anisotropy of MgB 2 are reviewed. The data are described within a weak coupling two-gaps anisotropic s-wave model of super-conductivity. The calculated ratio of the upper critical fields γ H = H c2,ab /H c2,c increases with decreasing temperature in agreement with available data, whereas the calculated ratio of London penetration depths γ λ = λ c /λ ab decrea...
