GEOLOGY: A Fresh Look

Sedimentary Geology and Human Origins: a Fresh Look at Olduvai Gorge, Tanzania

Recent field work at Olduvai Gorge (Tanzania) using sedimentary geology, in particular high-resolution paleoenvironmental reconstruction and isotope geochemistry, has revealed that freshwater was in proximity to a number of the rich fossil sites in Beds I and II (, 2.0–1.0 Ma). This paper presents the first geological evidence for springs associated with archaeological sites in this semiarid ri...

A fresh look at preoperative body washing

National guidelines do not support preoperative body washing to reduce surgical site infections, instead recommending bathing or showering with soap. Yet preoperative body washing continues to be widely used in many hospitals across Europe. This paper suggests that existing trials of preoperative body washing, upon which guidelines are based, are dated and proposes a new investigation of preope...

Hyperglycemia-induced hyponatremia: a fresh look.

that require Zn2t Zincon and the standard ZnSO4 solution were from J.T. Baker; Tris (THAM) and sodium tetraborate were Fisher Certified. The 2-amino-2methyl-1-propanol was from Sigma (pfs, lot No. 14C-3610) as were the Good’s buffers 4-morpholineethanesulfonic acid (MES) and 2-[2-hydroxy-1,1bis(hydroxymethyl)ethyl]aminoethanesulfonic acid (TES). The other Good’s buffers, N,N-bis(2-hydroxyethyl)...

A fresh look into pulsating PG1159 stars

To improve the understanding of the pulsational instabilities of some of the PG1159-type pre-white dwarfs we performed detailed stability analyses on helium star evolutionary models. With the canonical chemical compositions, pulsational instabilities were encountered for all stellar masses considered (0.57, 0.63, 0.7 M⊙). The blue boundary agrees satisfactorily with observations. The red edge, ...
