Shelf-life estimation of recombinant hepatitis B vaccine using R software in comparison with WHO manual protocol
Introduction: Pharmaceutical companies as well as food and cosmetics manufacturers are legally required to provide a shelf-life label on their products packaging as part of their stability study report. There are different recommended software like R software package and SAS which can perform as shelf-life estimating tools for analyzing the data achieved by the stability testing of drugs and va...
متن کاملBayesian Spatial NBDA for Diffusion Data with Home-Base Coordinates
Network-based diffusion analysis (NBDA) is a statistical method that allows the researcher to identify and quantify a social influence on the spread of behaviour through a population. Hitherto, NBDA analyses have not directly modelled spatial population structure. Here we present a spatial extension of NBDA, applicable to diffusion data where the spatial locations of individuals in the populati...
متن کاملSimultaneous RP-HPLC and UV Spectroscopic Method Development and Validation for Estimation of Ibandronate Sodium in Bulk and Pharmaceutical Dosage Form
The present study describes a simple, accurate, precise and cost effective UV-Vis Spectroscopic and RP-HPLC method for the estimation of Ibandronate sodium (IBN). The determination of Ibandronate sodium (IBN) was performed by both UV and RP-HPLC method using 215 nm as the determination wavelength. The drug was dissolved in NaOH solution (0.1N NaOH) for estimation in UV and in distilled water fo...
متن کاملA New Cost Model for Estimation of Open Pit Copper Mine Capital Expenditure
One of the most important issues in all stages of mining study is capital cost estimation. Determination of capital expenditure is a challenging issue for mine designers. In recent decade, quite a few number of studies have focused on proposing estimation models to predict mining capital cost. However, these efforts have not achieved to a predictor model with reliable range of error. Both of ov...
متن کاملTheory of home range estimation from displacement measurements of animal populations.
A theory is provided for the estimation of home ranges of animals from displacement measurement procedures. The theoretical tool used is the Fokker-Planck equation, its characteristic quantities being the diffusion constant which describes the motion of the animals, and the attractive potential which addresses their tendency to live in restricted regions, e.g., near their burrows. The measureme...
