Most energy and commodity markets exhibit mean-reversion occasional distinctive price spikes, which result in demand for derivative products protect the holder against high prices. To this end, paper we present a few fast efficient methodologies exact simulation of spot dynamics modelled as exponential sum Gaussian Ornstein-Uhlenbeck process an independent pure jump process, where latter one is...

To facilitate urine sample preparation prior to head-space gas-chromatographic (HS-GC) analysis. Urine samples containing one of the five solvents (acetone, methanol, methyl ethyl ketone, methyl isobutyl ketone and toluene) at the levels of biological exposure limits were aspirated into a vacuum tube via holder, a device commercially available for venous blood collection (the vacuum tube method...

Specimen transfer under controlled environment conditions, such as temperature, pressure, and gas composition, is necessary to conduct successive complementary in situ characterization of materials sensitive to ambient conditions. The in situ transfer concept is introduced by linking an environmental transmission electron microscope to an in situ X-ray diffractometer through a dedicated transmi...

Sorbent-TRACK is a new device developed to monitor adsorption and surface oxidation of pollutants under direct plasma exposure. It is based on direct transmitted Fourier Transformed Infrared (FTIR) spectroscopy. A pyrex reactor under controlled gas pressure and composition is inserted on the infrared beam of a commercially available Nicolet 5700 FTIR spectrometer. A substrate holder is located ...

Procedures involving phlebotomy are critical for obtaining diagnostic blood specimens and represent a well known and recognized problem, probably among the most important issues in laboratory medicine. The aim of this report is to show spurious hyperkalemia and hypocalcemia due to inadequate phlebotomy procedure. The diagnostic blood specimens were collected from a male outpatient 45 years old,...

We investigate the complexity of reactive sputtering highly conductive zinc oxide thin films in presence hydrogen at room temperature. report on importance precise geometric positioning substrate with respect to magnetron achieve maximum conductivity. examine electrical properties deposited thins based their position holder relative magnetron. By considering early reports by other researchers a...
