Proximate composition and physicochemical analyses were carried out on the seed and Sesame oil (Sesamum indicum L.). The results showed that the seed contained 5.7% moisture, 20% crude protein, 3.7% ash, 3.2% crude fiber, 54% fat and 13.4% carbohydrate. The seeds were found to be good sources of minerals. ± 4.21 mg/100g).The physical properties of the oil(More)
The combination of liquid chromatography and mass spectrometry (LC-MS) has been established to complement gas chromatography (GC)-MS in the analysis of non-volatile and labile drugs in complex materials. The possibilities of LC-MS in the pharmaceutical industry for the analysis of drug substances and dosage forms, metabolism studies and the elucidation of(More)
At the University of Twente, a 14.5 K hydrogen-based sorption cooler is under development. It can be used as a stand-alone 14.5 K cooler, or as a precooler, e.g., in combination with a 4 K helium-based sorption cooler. The advantage of sorption coolers is the absence of moving parts and, as a result, their vibration-free operation and, potentially, a very(More)
The introduced electrospray (ESP) technique combined with quadrupole mass spectrometry (MS) was applied for the trace residue detection (10 ppb) of commonly administered beta-lactam antibiotics in bovine milk. Because of the widespread use of penicillin G, ampicillin, amoxicillin, cephapirin, cloxacillin, and ceftiofur in veterinary medicine, these six(More)
In this paper, we introduce a charge integrator as a read-out system for piezoelectric cantilever sensors. The charge integrator is used to monitor the surface charge induced by piezoelectric materials as a function of mechanical stress. This technique improves the response of piezoelectric cantilever sensors in low frequency measurements which makes them(More)
Lactose crystallization and color changes in formulas containing beta-lactoglobulin and gelatinized starch were investigated. Model infant formulas were prepared by colyophilization of 3 components (lactose, beta-lactoglobulin, and gelatinized starch). A mixture design was used to choose the percentage of each mixture component. These formulas were stored(More)
The aim of this study was to investigate the applicability of the distance correction parameter (DCP) integrated to the case-based prediction system CONSTUD to reduce the effect of spatial autocorrelation of training data in machine learning process. To achieve this, calculated similarity between observations is decreased by the so-called distance(More)
