In this brief note, we prove the following two Artin-Schreier curves are supersin-gular.

a fast and simple modified quechers (quick, easy, cheap, rugged and safe) extraction method based on spiked calibration curves and direct sample introduction was developed for determination of benzo[a]pyrene (bap) in bread by gas chromatography-mass spectrometry single quadrupole selected ion monitoring (gc/ms-sq-sim). sample preparation includes extraction of bap into acetone followed by clean...

      In this study, 60 composite samples of dill and onion from two different cultivated areas in Khozestan province, Iran, were collected and analyzed for the presence and determination of lead and cadmium by flame atomic absorption spectrometry. Samples were burned according to AOAC at 450 °C, and the residue was dissolved in nitric acid. Lead and Cadmium contents were determined using calib...

The data points in Figure 4c are not affected, however the fitting curves are. These can be readjusted by modifying the fitting parameters to take into account the increased temperature. This can be done by altering the thermal expansion co-efficient from 114*10−7K−1 (20–40 °C) to 119*10−7K−1. The fitting parameter, n, remains as 0.84 by slightly decreasing the empirical calibration constants (...

OBJECTIVE Our objective was to validate the Pediatric Index of Mortality (PIM) and PIM2 scores in a large cohort of children from a developing country. DESIGN Prospective observational study. SETTING Pediatric intensive care unit of a tertiary care teaching hospital. PATIENTS All children aged <18 years admitted between June 2011 and July 2013. MEASUREMENTS AND MAIN RESULTS We evaluated...

Cucumber is one of the main vegetables in Iranian food basket. A wide range of pesticides are used for crops protection during the cultivation of vegetables such as cucumber due to heavy pest infestation. Analysis of pesticide residues in food and other environmental commodities have become essential requirement for consumers, producers, and food quality control authorities. This study was aime...

A multiple-curve Heath-Jarrow-Morton (HJM) forward rate model driven by time-inhomogeneous Lévy processes is presented. In this approach to model spreads between curves for different tenors, credit as well as liquidity risk is taken into account. Deterministic conditions are derived to ensure the positivity of spreads and thus the monotonicity of the curves for the various tenors. Valuation for...
