Background and Aim: Expanded program on immunization is one of the strategic universally accepted methods for control of childhood diseases including poliomyelitis. Oral Polio Vaccine (OPV) which consists of live attenuated poliovirus is considered as appropriate and most convenient tool for nation-wide vaccination. Polio virus is sensitive to heat, so OPV should be kept frozen and transferred ...
A TCP-targeted low-rate denial of service (LDoS) attack exploits the vulnerabilities TCP congestion control mechanism. The most widely used algorithm, CUBIC, increases resilience to LDoS. This paper explores high-potency patterns LDoS attacks against CUBIC under RED queue management scenario, and develops two models, D- S-models maximize potency (i.e., damage-to-cost ratio). Theoretical analyse...
for evaluation the stability and potency of anthrax vaccine prepared in razi vaccine and serum research institute in iran, samples of different batches of vaccine were kept at 4-8 °c (refrigerator), 20-25 °c (room temperature) and 37 °c (incubator).the viable spores/ml of vaccines were determined using plate–counting method before and after holding at different temperatures monthly. vaccine pot...
This paper describes the use of an automatic classifier to model group potency levels within software development projects. A set of machine learning experiments that looked at different group characteristics and various collaboration measures extracted from a team’s communication activities were used to predict overall group potency levels. These textual communication exchanges were collected ...
Potency control of inactivated rabies vaccines for human and veterinary application is usually undertaken by vaccination-challenge tests (e.g. the mouse potency test). For practical and ethical reasons there is an urgent need to replace in vivo potency control procedures, at least in part, by reliable methods of in vitro potency testing. Quantitative ELISA systems for potency control were devel...
objective: this study designed to test the antibacterial potency of enrofloxacin (enr) and essential oils from zataria multiflora boiss (zeo) and trachyspermum copticum (teo)on aeromonas hydrophila. material and methods: the antibacterial potency of test compounds was determined by several methods including the inhibition zone diameter determination, microbroth dilution method and colorimetric ...
A convenient standard microbiological potency determination test for the antidandruff shampoos was developed by adopting the pharmacopoeial microbiological assay procedure of the drug nystatin. A standard curve was drawn consisting of the inhibition zone diameters vs. logarithm of nystatin concentrations in international units using the fungus Saccharomyces cerevisiae (yeast) strain National Co...
