A method for repeatable loading of propranolol hydrochloride as a model drug onto the ion exchanger Amberlite TM IRP69 was developed and different parameters for the loading process were evaluated due to their impact of the extent of loading. It was found that the extent of loading in equilibrium is widely independent of the experimental method used. However, a magnetic stirrer comminutes the i...

BACKGROUND Oral candidiasis is an infection caused by a yeast-like fungus called Candida. Various methods can be used to isolate Candida from the oral cavity. However, it is difficult to correctly and satisfactorily diagnose oral candidiasis because currently no microbiological or laboratory standards based on samples from the oral cavity are available. The aim of this study is to establish a r...

A reliable and sensitive analytical method was developed for simultaneous determination of deoxynivalenol(DON), 3-acetyldeoxynivalenol (3-ADON), 15-acetyldeoxynivalenol (15-ADON), fusarenon X (FUS-X), and masked deoxynivalenol (deoxynivalenol-3-glucoside, D3G) in formula feed, concentrated feed, and premixed feed products. The method was based on an improved sample pretreatment with the commerc...

The validity of estimating the solid phase diffusion coefficient, D s , of a lithium intercalation electrode from impedance measurement by a modified electrochemical impedance spectroscopy ~EIS! method is studied. A macroscopic porous electrode model and concentrated electrolyte theory are used to simulate the synthetic impedance data. The modified EIS method is applied for estimating Ds . The ...

This paper focuses on the finite element based fatigue life prediction of lower suspension arm, subjected to variable amplitude loading. The objectives of this study are to predict fatigue life of the lower suspension arm using stress-life and strain-life methods, to investigate the effect of the mean stress. The lower suspension arm was developed using computer aided design software. The finit...

BACKGROUND Cerebrospinal fluid (CSF) has been used to identify biomarkers of neurological disease. CSF protein biomarkers identified by high-throughput methods, however, require further validation. While Western blotting (WB) is well-suited to this task, the lack of a validated loading control for CSF WB limits the method's accuracy. NEW METHOD We investigated the use of total protein (TP) as...

Sensitive shells are a class of constructions with specific and perhaps unintuitive responses to different loading scenarios. There new emerging applications for capsules open cavities, as the designs optimised maximise payload, sensitivity has be taken into account. Concentrated loads induce singularities that propagate along characteristics surfaces. Perforation patterns do not have strong ef...
