Anomalous Properties of Some Fluids − with High Relevance in Energy Engineering − in Their Pseudo-critical (Widom) Region

Recent results are shown about the peculiarities of the pseudo-critical region, with special emphasis on properties important for energy production and conversion. The property-map of some materials, which are relevant as model fluids or as working / cooling fluids in energy engineering (argon, methane, water and carbon dioxide) and their relative positions to various adiabats – influencing their stability through the anomalous properties – are presented. Some potential technological problems related to the existence of these anomalies are discussed

REVIEW AND CONTRIBUTION TO THE ODONATA FAUNA OF SĂLAJ COUNTY, ROMANIA

An annotated list of 17 Odonata species from Sălaj county, Romania, collected in 2014 and 2015 are given. Twelve species (Calopteryx virgo virgo (Linnaeus, 1758), Lestes viridis Vander Linden, 1825, Coenagrion pulchellum (Vander Linden, 1825), Ischnura pumilio (Charpentier, 1825), I. elegans pontica Schmidt, 1938, Aeshna affinis Vander Linden, 1823, A. cyanea (Müller, 1764), Cordulegaster heros Theischinger, 1979, Somatochlora meridionalis Nielsen, 1935, Libellula depressa Linnaeus, 1758, Orthetrum coerulescens coerulescens (Fonscolombe, 1837), Orthetrum brunneum (Fonscolombe, 1837)) are new records for the area. The occurrence of Cordulegaster heros Theischinger, 1979 is the most important result, the rare L. viridis and S. meridionalis are also worth to mention

Extramitochondrial OPA1 and adrenocortical function

We have previously described that silencing of the mitochondrial protein OPA1 enhances mitochondrial 27 Ca2+ signaling and aldosterone production in H295R adrenocortical cells. Since extramitochondrial OPA1 28 (emOPA1) was reported to facilitate cAMP-induced lipolysis, we hypothesized that emOPA1, via the 29 enhanced hydrolysis of cholesterol esters, augments aldosterone production in H295R cells. A few 30 OPA1 immunopositive spots were detected in �40% of the cells. In cell fractionation studies OPA1/COX 31 IV (mitochondrial marker) ratio in the post-mitochondrial fractions was an order of magnitude higher 32 than that in the mitochondrial fraction. The ratio of long to short OPA1 isoforms was lower in post-mito- 33 chondrial than in mitochondrial fractions. Knockdown of OPA1 failed to reduce db-cAMP-induced phos- 34 phorylation of hormone-sensitive lipase (HSL), Ca2+ signaling and aldosterone secretion. In conclusion, 35 OPA1 could be detected in the post-mitochondrial fractions, nevertheless, OPA1 did not interfere with 36 the cAMP – PKA – HSL mediated activation of aldosterone secretio
