OBJECTIVE--To describe the characteristics of patients attending their general practitioners
and complaining of fatigue or being "tired all the time." DESIGN--Prospective study of cohort …

… The argon plasma reaches temperatures of 8000–10000 K and thus can easily ionize
elements that have lower ionization energies than argon (15.76 eV). The ionization efficiency of …

As a preliminary investigation towards obtaining composite carbon nanotube composite
adsorbents for CO 2 capture, in this study chitosan was impregnated onto the surface of multi-…

BACKGROUND: Few prospective studies have been carried out in primary care on patients
presenting with tiredness. AIM: A study was undertaken to describe patients whose main …

As a preliminary investigation towards obtaining carbon nanotube composite adsorbent for
CO 2 capture, in this study CO 2 adsorption performance of three commercial carbon …

… The granulite is made up mostly of K-feldspar (up to 93%) and garnet relatively rich in pyrope
(~ 30 molar %), which has been partly replaced by biotite during the retrograde stages of …

We introduce and propose zircon M257 as a future reference material for the determination
of zircon U‐Pb ages by means of secondary ion mass spectrometry. This light brownish, …

The LA ‐ ICP ‐ MS U‐(Th‐)Pb geochronology international community has defined new
standards for the determination of U‐(Th‐)Pb ages. A new workflow defines the appropriate …

We investigated the Neoproterozoic–early Paleozoic evolution of the Gondwanan margin of
the north-central Andes by employing U-Pb zircon geochronology in the Eastern Cordilleras …

… The major-element chemistry is, in many respects, similar to that of the segregated granite
from the same section (SK12, Table 2), excepting K 2 O abundances that are much higher in …
