(EDP Sciences, 2020)Aims. Cometary globules, dense molecular gas structures exposed to UV radiation, are found inside HII regions. Understanding the nature and origin of these structures through a kinematic study of the molecular gas could ...
-
(IOP, 2022)We report the first 3D kinematical measurements of 88 stars in the direction of several recently discovered substructures in the southern periphery of the Large Magellanic Cloud (LMC) using a combination of Gaia proper ...

(IOP PUBLISHING LTD, 2012-05-20)We estimated the dynamical surface mass density Sigma at the solar position between Z = 1.5 and 4 kpc from the Galactic plane, as inferred from the kinematics of thick disk stars. The formulation is exact within the limit ...
-
(IOP Publishing, 2017)We use 3 mm multiline and continuum CARMA observations toward the first hydrostatic core (FHSC) candidate L1451-mm to characterize the envelope kinematics at 1000 au scales and investigate its evolutionary state. We detect ...
-
(Blackwell, 2017)West verging thrusts, synthetic with the Nazca-South America subduction interface, have beenrecently discovered at the western front of the Andes. At ~33°300S, the active San Ramón fault stands asthe most frontal of these ...

(Royal Society of Chemistry, 2015)© The Royal Society of Chemistry 2015.Carbon monoxide hydrogenation was studied over a γ-alumina-supported 1 wt% Rh catalyst by means of kinetic and in situ infrared measurements. The study was carried out at 200-300 °C, ...
-
(1998)Background: Induction of salivation is becoming increasingly popular in the assessment of salivary gland status. Various mechanical or pharmacological procedures are empirically used to produce salivation. Oral stimulation ...
-
(1984)The kinetic mechanisms of Escherichia coli phosphofructokinase-2 (Pfk-2) and of the mutant enzyme Pfk-2* were investigated. Initial velocity studies showed that both enzymes have a sequential kinetic mechanism, indicating ...
-
(1976)Functional micelles of hexadecyl(2-hydroxyethyl)dimethylammonium bromide (I) are better catalysts than hexadecyltrimethylammonium bromide (CTABr) for the alkaline hydrolysis of diethyl and di-n-hexyl p-nitrophenyl phosphate ...
-
(1965)Apyrase from potato extracts has been purified 200-fold by two different procedures; both procedures furnish an apyrase which splits ATP faster than ADP. By using P32-labeled substrates, it was possible to demonstrate that ...
-
(Biophysical Society, 2003)Fast Ca2+ release kinetics were measured in cardiac sarcoplasmic reticulum vesicles actively loaded with Ca2+. Release was induced in solutions containing 1.2 mM free ATP and variable free [Ca2+] and [Mg2+]. Release rate ...
-
(2003)The kinetic mechanism of rat liver hexokinase D (‘ glucokinase’) was studied under non-co-operative conditions with 2- deoxyglucose as substrate, chosen to avoid uncertainties derived from the co-operativity observed ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2000-03)The reaction between 2-p-methoxyphenyl-4-phenyl-2-oxazolin-5-one and 2,2,6,6-tetramethyl-1-piperidinyl-N-oxide (TEMPO) in benzene as the solvent generates quantitatively 4,4'-bis-[2-p-methoxyphenyl-4-phenyl-2-oxazolin-5-one]. ...
-
(1997)The sensitized photo-oxidation of boldine and its permethylated derivative, glaucine, has been studied in several solvents using steady-state kinetic methods. Values of kB, the total rate constant for the reaction between ...
-
(EDP Sciences, 2013)Context. It is well known that the kinetic temperatures, Tkin, of the molecular clouds in the Galactic center region are higher than in typical disk clouds. However, the Tkin of the molecular complexes found at higher ...
-
(1984)The number and nature of glucose-phosphorylating enzymes of rat intestinal mucosa were investigated by chromatographic, electrophoretic, and kinetic methods. Three fractions with glucose-phosphorylating activity were ...
-
(1999)St I is a toxin present in the Caribbean Sea anemone Stichodactyla helianthus which is highly hemolytic in the nanomolar concentration range. Exposure of the toxin to free radicals produced in the pyrolysis of 2,2′ ...
