With the increasing consumption of hemp seed products, it is important to establish whether biological samples from consumers contain trace cannabinoids that could mistakenly be attributed to cannabis abuse. Thus, we analyzed whether the cannabinoids, 11-nor-9-carboxy-tetrahydrocannabinol, cannabidiol, and cannabinol, can be detected in the urine of ...

Stress sensitivity of coal samples in terms of anisotropy
Journal of Coal Science and Engineering (China), 2013The permeability and porosity of coal seams are anisotropic, and the variation of confining stress may induce deformation in coal samples. In order to study these characteristics, experiments and model analyses were conducted to understand the behaviors of anisotropic stress sensitivity of lean coal samples.

A technique for long-term storage of clay samples
Canadian Geotechnical Journal, 1986This note describes a technique for sealing and storing clay samples so as to prevent aging effects during long periods of storage. It also gives the results of a study carried out on samples stored from 3 to 8 years, which prove the efficiency of that technique; the liquid limits, the liquidity indices, and the pH values remained constant during ...

Long-term conductivity decrease in polyacetylene samples
Synthetic Metals, 1985Abstract Investigations of the conductivity decrease of polyacetylene samples doped with iodine, AsF 5 and FeCl 3 , respectively, and stored under various conditions (laboratory atmosphere, dry and humid air, vacuum, argon, argon at −30 °C) are reported.

Dynamical Sampling with a Burst-like Forcing Term
2019 13th International conference on Sampling Theory and Applications (SampTA), 2019In this paper we consider the problem of recovery of a burst-like forcing term in the framework of dynamical sampling. We introduce the notion of a sensing limit of a collection of samples with respect to a semigroup and indicate its fundamental role in the solvability of the problem.

Analysis of long term samples in Tore Supra
Journal of Nuclear Materials, 1995Abstract Long term samples have been installed on the inner wall in Tore Supra to monitor the surface modification of the graphite tiles. Surface analyses have shown a very low metallic impurity concentration (∼ 10 16 at/cm 2 ) dominated by stainless steel compounds.

How Long to Air Sample? Practical Considerations for Short-Term Air Sampling
Health Physics, 2011Transportable (e.g., "giraffe") air samplers can be used for both short-term "grab-sampling" situations involving a few minutes to several hours, as well as for long-term retrospective air sampling situations that typically last a week. It is the short-term coverage situation which begs the question: "how long a sampling time is adequate?" The basis ...

Gibbs Sampling for Long-Term Survival Data with Competing Risks
Biometrics, 1998Many researchers use the 5-year survival probability as a measurement of cure for long-term survival data. In addition to this probability, a mixture model with possibility of cure provides a predictive probability of cure given that a patient has survival to a period of time.
