Comparative toxicity studies using unconfounded exposures can prioritize the selection of sensitive sentinel test species and can refine methods for evaluating ecological risks of complex constituents like naphthenic acids (NAs), a group of problematic organic acids associated with crude oils and energy-derived waters. Unconfounded exposures of NAs can be prepared with relatively stable and rep...

All Fmoc (9-fluorenylmethoxycarbonyl) protected amino acids, NovaSyn TG Sieber resin, and coupling reagents (HOBt, 1-Hydroxybenzotriazole, HATU, 1-[Bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5b]pyridinium 3-oxid hexafluorophosphate, and PyBOP, (Benzotriazol-1-yloxy)tripyrrolidinophosphonium hexafluorophosphate) were purchased from Novabiochem. All solvents, used in the synthesis and purif...

In this study, total crocin was extracted from saffron stigmas using crystallization method. Ethanol 80% was selected as the best extraction solvent. Crystallization process was carried out in one and two steps at different temperatures. Ethanol 80% was used as crystallization medium. Crocin crystals obtained from the first crystallization had low purity and thus were subjected to the second cr...

This paper discusses an intercomparison campaign performed in the mixed radiation field at the CERN-EU (CERF) reference field facility. Various instruments were employed: conventional and extended-range rem counters including a novel instrument called LUPIN, a bubble detector using an active counting system (ABC 1260) and two tissue-equivalent proportional counters (TEPCs). The results show tha...

Kaolinite particles from two different sources (Fluka and Clay Minerals Society (CMS)) were examined with respect to their ability to act as ice nuclei (IN). This was done in the water-subsaturated regime where often deposition ice nucleation is assumed to occur, and for watersupersaturated conditions, i.e., in the immersion freezing mode. Measurements were done using a flow tube (the Leipzig A...

We discuss here Quantum molecular dynamics models (QMD) and Dual Parton Models (DPM and QGSM). We compare RHIC data to DPM–models and we present a (Cosmic ray oriented) model comparison. The emphasis of this contribution is to high energies, therefore, QMD non–relativistic models (E < 2AGeV) are not treated here. The first relativistic QMD model was RQMD [1]. This model is no longer supported s...
