Resonance-enhanced laser-induced breakdown spectroscopy was used to increase the elemental sensitivity of laser-induced breakdown spectroscopy. In resonance-enhanced laser-induced breakdown spectroscopy, two lasers are used. The first laser creates a plasma, and the second laser re excites the most …

This bachelor thesis reports on a study conducted at the research institute IMARES in the Netherlands. It focused on plastics ingested by northern fulmars (Fulmarus glacialis) around the North Sea region as a contribution to a better understanding of the fulmar in its role as an indicator for marine …

A high resolution infrared spectrum of species formed in a nitrogen-hydrogen plasma expansion was recorded. A cavity ring down detection scheme was used to record a rotationally resolved spectrum in the region from 3300 cm-1 to 3380 cm-1. Using the relative intensities and line positions it was determined …

Single Fiber Reflectance spectroscopy (SFR) can be used to determine tissue optical properties such as scattering and absorption. The SFR technique employs a semi-empirical modal, which contains a parameter that is dependent on the fiber numerical aperture, NA . However, the NA is a wavelength dependent …

Microencapsulation of cells is a promising approach to prevent rejection in the absence of immunosuppression. Clinical application, however, is hampered by insufficient insight in factors influencing biocompatibility of the capsules in humans. In the present study we exposed alginate-based capsules prepared …

To investigate whether oxygen consumption and blood flow at rest and after exercise are lower in the affected arm of patients with repetitive strain injury (RSI) compared to controls, and lower in the healthy nonaffected forearm within patients with unilateral RSI. RSI is considered an upper extremity …

The reaction of the alkyl complexes Cp*2LnCH(SiMe 3)2 (Ln = Y 1-Y, Ce 1-Ce, La 1-La; Cp* = η5-C5Me5) and Me2Si(η 5-C5Me4)2LnCH(SiMe3) 2 (Ln = Ce 5-Ce) with 1-methylalk-2-ynes CH3C≡CR (R = Me 3a, Et 3b, nPr 3c, tBu 3d, SiMe3 3e, Ph 3f, C6H4Me-2 3g, C6H3Me 2-2,6 3h, C6H3iPr2-2,6 3i, C6F5 3j) affords the …

Seven new 1,3,5-cyclohexyltricarboxamide-phenylalanine derivatives were synthesized in order to investigate the effect of the amino acid chirality on the gelating properties of these small molecules in water. Gelation tests have shown that enantiomerically pure homochiral 1,3,5-cyclohexyltricarboxamide-L-phenylalanine …

Mycotoxins are small (MW approximately 700), toxic chemical products formed as secondary metabolites by a few fungal species that readily colonise crops and contaminate them with toxins in the field or after harvest. Ochratoxins and Aflatoxins are mycotoxins of major significance and hence there has …
