Conodont dating of some Telychian (Silurian) sections in Estonia [PDF]

Estonian Journal of Earth Sciences, 2008
Several Telychian–Sheinwoodian strata exposed in Estonia are precisely dated using conodont biostratigraphy. The beds in the Valgu-1 section correspond to the uppermost Distomodus staurognathoides and Pterospathodus eopennatus ssp. n. 1 zones.

Positive end-expiratory pressure during resuscitation at birth in very-low birth weight infants: A randomized-controlled pilot trial

Pediatrics and Neonatology, 2018
Background: There is limited evidence of the effect of positive end-expiratory pressure (PEEP) during resuscitation soon after birth. Premature neonates may experience respiratory distress from surfactant insufficiency and providing PEEP after the very ...

Feasibility of titrating PEEP to minimum elastance for mechanically ventilated patients

Pilot and Feasibility Studies, 2015
BackgroundSelecting positive end-expiratory pressure (PEEP) during mechanical ventilation is important, as it can influence disease progression and outcome of acute respiratory distress syndrome (ARDS) patients.

Investigation of Moisture‐Induced Degradation Mechanisms and a Reviving Strategy for Sulfide‐Based Solid Electrolytes in All‐Solid‐State Composite Cathode

Advanced Energy Materials, EarlyView.
Moisture exposure induces the formation of reductive solid phases on argyrodite Li6PS5Cl, which destabilize Ni‐rich cathodes by extracting lattice oxygen and inducing surface reconstruction. A brief oxygen‐assisted annealing treatment quenches these reductive phases, restores interfacial stability, and enables effective regeneration and reuse of ...

Variation of poorly ventilated lung units (silent spaces) measured by electrical impedance tomography to dynamically assess recruitment

Critical Care, 2018
Background Assessing alveolar recruitment at different positive end-expiratory pressure (PEEP) levels is a major clinical and research interest because protective ventilation implies opening the lung without inducing overdistention.

Electrochemical and Thermal Interplay in Blended Cathodes for All Solid‐State Batteries

Advanced Energy Materials, EarlyView.
This work analyzes blended LFP‐NMC cathodes for all solid state batteries, revealing their balanced rate performance and enhanced thermal properties. Operando X‐ray diffraction studies uncovered lithiation gradients and asymmetric charging effects due to kinetic limitations.

Fine Tuning of Catalyst Active Sites to Access Advanced Ultrahigh‐Melting Polyolefins

Angewandte Chemie, EarlyView.
A redesign of the active site of the pyridylamido hafnium (Hf) catalysts can enhance the performance of this catalyst family and unlock previously inaccessible polymer structures. When the catalyst is precontacted with allyltrimethylsilane the active species is modified and the catalyst experiences a new life becoming able to polymerize sterically ...

Effect of supplementing oxygen with positive end expiratory pressure during elective caesarean section under spinal anaesthesia on foetus

Journal of Anaesthesiology Clinical Pharmacology, 2010
Background: It is known fact that pre-oxygenation with positive end-expiratory pressure (PEEP) improves the Partial pressure of oxygen (PO 2 ). In this regard not many studies have been done in pregnant women to know its effect on foetus.
