A Comparative Phytochemical Analysis of Olive Oils Derived From Two Underexplored Tunisian Cultivars: Chemchali and Fougi

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study represents the first comprehensive investigation into the valorization of two rare olive cultivars, Chemchali and Fougi, cultivated in southern Tunisia. The main objectives were to assess the quality of their virgin olive oils (VOOs) by analyzing their chemical composition, sensory profile, quality indices, and physicochemical ...

Precision spectroscopy of helium [PDF]

The sixteenth international conference on atomic physics, 1999
Accurate Quantum-Electrodynamics (QED) tests of the simplest bound three body atomic system are performed by precise laser spectroscopic measurements in atomic Helium. In this paper, we present a review of measurements between triplet states at 1083 nm (23S-23P) and at 389 nm (23S-33P).

The Helium Question [PDF]

Science, 1979
Helium appears indispensable for certain energy-related uses that may be important 50 years from now, when helium-bearing natural gas, a much cheaper source than air, may be exhausted. Present demand, however, is lower than productive capacity, and much helium is being dissipated into the atmosphere as natural gas is burned for fuel.
