Glass Fiber Reinforced Plastic composites have an increased application in recent days, due to its enhanced structural, mechanical and thermal properties. The heterogeneous nature of this kind of materials makes complications during machining operations. Drilling of holes in GFRP becomes almost unavoidable in fabrication. However, drilling is a common machining practice for assembly of componen...

Lead-acid batteries are commonly used as power sources for critical operations in the world. They find application air-traffic control towers, uninterruptible supplies (UPS), railroad crossings, military installations, hospitals, and weapons systems. also known automotive industrial batteries. consist of large amounts lead, sulphuric acid, plastics. The acid is tremendously irritant a carrier s...

When several treatments are available for evaluation in a clinical trial, different design options are available. We compare multi-arm multi-stage with factorial designs, and in particular, we will consider a 2 × 2 factorial design, where groups of patients will either take treatments A, B, both or neither. We investigate the performance and characteristics of both types of designs under differ...

The aim of this study is to prepare fluvastatin nanostructured lipid carriers (FLV-NLCs) in order to find an innovative way to alleviate FLV-associated disadvantages. The limitations include poor solubility and extensive first-pass metabolism, resulting in low (30%) bioavailability and short elimination half-life (1-3 hours). FLV-NLCs were prepared by hot emulsification-ultrasonication method. ...

BACKGROUND Despite its potential benefits over univariate, chemometrics is rarely utilized for optimizing sequential injection analysis (SIA) methods. Specifically, in previous vis-spectrophotometric SIA methods, chemometrically optimized conditions were confined within flow rate and reagent concentrations while other conditions were ignored. RESULTS The current manuscript reports, for the fi...
