This paper introduces a recent work by a joint effort between Air Products and Sikama International on alpha trials of a production-scale furnace for flux-free wafer bump reflow based on electron attachment (EA).
A novel hydrogen activation technology based on electron attachment (EA) is developed for fluxless soldering at ambient pressure and normal soldering temperature. The technology has a potential to be used for a list of applications in the electronics packaging industry.
In this paper we demonstrate a recursive method for obtaining the moments of the generalized hyperbolic distribution. The method is readily programmable for numerical evaluation of moments. For low order moments we also give an alternative derivation of the moments of the generalized hyperbolic distribution. The expressions given for these moments may be used to obtain moments for special cases such...
Neutralizing antibody responses elicited during infection generally confer protection from infection. Hepatitis C virus (HCV) encodes two glycoproteins E1 and E2 that are essential for virus entry and are the major target for neutralizing antibodies. To assess whether both glycoproteins are required for the generation of a neutralizing antibody response, rodents were immunized with a series of glycoproteins...
We initially evaluated in mice the ability of naked DNA encoding intracellular forms of the E1E2 envelope proteins from HCV to induce antibody responses and compared the responses induced with the same plasmid adsorbed onto cationic poly (lactide co-glycolide) (PLG) microparticles. Although naked DNA was only able to induce detectable responses at the 100μg dose level, making this approach impractical...
