Catalytic synthesis of high-density C20-C38 isoparaffins
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19621. A study was made of the catalytic dimerization of five oiefins, namely C10-C19 trisubstituted ethylene derivatives, and the products of the hydrogenation of these dinners were prepared. 2. In the course of the dimerization partial isomerization of the dimers occurred. 3.

Thermal Stability of Carbinofullerenes C38, C62, and C64
Physics of the Solid State, 2020The thermal stability of recently predicted carbinofullerenes C38, C62, and C64 was examined using the molecular dynamics method. Their decomposition channels and temperature dependences of the lifetime were characterized. The activation energies and frequency factors in the Arrhenius law were determined.

Synthesis of the C38–C54 spiroketal segment of halichondrin B
Tetrahedron Letters, 2012Abstract Stereoselective synthesis of the C38–C54 segment of a marine metabolite halichondrin B comprising KLM and N rings with a C44 spiroketal including 10 chiral centers is described. The salient features of the synthesis are Carreira’s addition, Sharpless asymmetric dihydroxylation and double alkylation of TosMIC strategy and double vinyl ...

Colicin V38 and Microcin C38 Produced by Escherichia coli Strain 38
Avian Diseases, 1997Escherichia coli strain 38, an isolate from turkeys, has been previously shown to produce one or more broad-spectrum bacteriocins against other related enteric bacteria. Using a collection of E. coli strains that synthesized well-characterized colicins or microcins, along with a set of colicin/microcin-insensitive mutants, we were able to classify the ...

Die letzten und besten der australischen Dampfschnellzugloks waren die 30 „C38“- Pazifiks der New South Wales Government Railways, gebaut zwischen 1943 und 1949. Die Konstruktionsarbeiten begannen zwar schon vor dem Krieg, aber die meisten von ihnen konnten erst nach Kriegsende geliefert werden.

Kinetic investigation of C38 steel corrosion in concentrated perchloric acid solutions
Materials Chemistry and Physics, 2010The corrosion behaviour of steel at various concentrations of perchloric acid was studied by weight loss method in temperature range from 298 to 323 K. Results obtained show that corrosiveness of acid increases with its concentration and temperature. The logarithm of corrosion rate was plotted against the acid concentration and values of Hammett Ho and

Abstract C38: HNF4a regulates progression and molecular subtype of pancreatic ductal adenocarcinoma
Cancer Research, 2019Abstract Pancreatic ductal adenocarcinoma (PDAC) is an extremely aggressive malignancy in which the vast majority of patients succumb to disease. Transcriptomic analysis has identified two major molecular subtypes of PDAC, classical and basal-like.

[A new multi-channel LDR/MDR-afterloading-system (Inter-Pal-C38)].
Strahlentherapie und Onkologie : Organ der Deutschen Rontgengesellschaft ... [et al], 1990The methods of temporary interstitial implantation of iridium-192 seed chains have been applied in Erlangen for two years in many cases of squamous cell carcinoma in the head and neck area, the cervix uteri or the anal duct. The afterloading procedure which at the beginning had to be performed manually involved partially considerable radiation ...
