We compared two consensus primer PCR human papillomavirus (HPV) genotyping methods for the detection of individual HPV genotypes and carcinogenic HPV genotypes as a group, using a stratified sample of enrollment cervical specimens from sexually active women participating in the NCI/Costa Rica HPV16/18 Vaccine Efficacy Trial. For the SPF(10) method, DNA was extracted from 0.1% of the cervical sp...

Superplasticforming (SPF) has become an important manufacturing method for aerospace and fuselage components. The basic reasons for the popularity of this process are reviewed and the compatibilityoffine-grained INCONELB alloy71 8SPF@ to superplasticforming are presented in this paper. The temperature limitations of current aluminum and titanium alloys employed in SPF parts for gas turbine comp...

Nonlinear stochastic dynamical systems are widely used to model physical processes. In many practical applications, the state variables are defined on a compact set of the state space, i.e., they are bounded or saturated. To estimate the states of systems with saturated variables, the Saturated Particle Filter (SPF) has recently been developed. This filter exploits the structure of the saturate...

RT-PCR for the detection of Newcastle disease virus (NDV) in allantoic fluids of SPF embryonated eggs as well as in tissues of SPF chickens infected experimentally is described. The method proved to be specific as all tested NDVs were detected and no cross reaction with other RNA viruses was observed. Sensitivity of the method was established at 10ELD50/0.1 ml. To detect NDV in chicken tissues,...

Recent researches present that packet-mode scheduling may provide overall performance advantages over cell-mode scheduling in input queueing switches. But one significant drawback of existing packet-mode schedulers is that they tend to result in longer waiting time of short packets, whose delay is critical to the performance of IP networks. To mitigate the problem, this paper proposes a simple ...

The Sun Protection Factor (SPF) is the most important data to quantify the effectiveness of a sunscreen, being universally accepted. The method is based on determining the minimum erythematous dose (MED), defined as the smallest amount of energy required for triggering the erythema, in areas of protected and unprotected skin. The SPF value is then calculated as the ratio between the MED of prot...

The coagulation of β-conglycinin (7S), glycinin (11S) and isoflavones induced by calcium chloride was investigated. Approximately 92.6% of the soymilk proteins were coagulated into the soymilk pellet fraction (SPF) after the addition of 5 mM calcium chloride. SDS-PAGE and two-dimensional electrophoresis analysis indicated that most of the 7S (α', α and β), 11S acidic (A1a, A1b, A2, A3 and A4) a...

We study algorithms for the minimum mean cycle problem, a parametric version of shortest path feasibility (SPF). The three basic approaches to the problem are cycle-based, binary search, and tree-based. The first two use an SPF algorithm as a subroutine, while the latter uses a parametric approach. When implementing the SPF-based methods, one has a choice of SPF algorithms and incremental optim...

Supernatant protein factor (SPF) and anionic phospholipids such as phosphatidylglycerol (PG) stimulate squalene epoxidase activity in rat liver microsomes by promoting ['Hlsqualene uptake as well as substrate translocation (Chin, J., and K. Bloch. 1984. J Biol. C h . 259: 11735-11738). This process is postulated to be membrane-mediated and not carriermediated. Here we show that treatment of PG ...
