Abstract Composite thermoelectric materials based on layered calcium cobaltite Ca 3 Co 4 O 9 + δ doped with copper particles were synthesized by two-step sintering, and their microstructure, electrotransport properties studied. It was determined that the introduction of into ceramics improves sinterability at moderate sintering temperatures ( T sint ≤ 1273 K), leading to a decrease in porosity ...

Sunni exegetes repeatedly assert the authority of Qur’an to explain itself, and prophetic tradition (ḥadīth) or early interpretations when explanations cannot be found in Qur’an. Yet treatment that Queen Sheba receives by reveals that, contrary their assertions, they are influenced products cultural social milieux. This leads increasingly androcentric accretions exegetical depart noticeably fro...

We would like to provide a clarification to the reader about our article ‘‘Efficacy and Treatment Costs of Monotherapy with bDMARDs in the Treatment of Rheumatoid Arthritis in Patients Intolerant to or Inappropriate to Continue Treatment with Methotrexate’’ published in issue 33, pp 1360–1373. In Italy tocilizumab adheres to the payback system, so its ex-factory price does not include the ex-an...

[1] The water solubility in pyrope-rich garnet was determined between pressures of 5–9 GPa and temperatures of 1373– 1473 K under silica activity and oxygen fugacity similar to those expected in the Earth’s upper mantle. We found that pyrope-rich garnet has substantial water solubility up to 0.1 wt% under these conditions. In addition, the water content in garnet varied as a function of chemica...

Platelets are small anucleate blood cells that aggregate to seal leaks at sites of vascular injury and are important in the pathology of atherosclerosis, acute coronary syndromes, rheumatoid arthritis, cancer, and the regulation of angiogenesis. In all cases, platelet aggregation requires release of stored proteins from -granules. However, how proteins with potentially antagonistic functions ar...

The interplay of screw dislocations with carbon atoms is investigated in tungsten at high temperature using situ straining experiments a transmission electron microscope (TEM) and through ab initio calculations. When the enough to activate diffusion, above 1373 K, segregates core modifies their mobility, even for concentration as low 1 appm. TEM observations reveal reappearance Peierls mechanis...
