About the Influence of SiO2 on the Temperature Behaviour of Ruthenate Based Thick Film Resistors

open access: yesActive and Passive Electronic Components, 1987
Substituting glass by SiO2 in thick film resistors results in a small increase of R□, a decrease of dR□/dT and an increase of d2R□/dT2 (at room temperature).

Genome-wide multi-parametric analysis of H2AX or γH2AX distributions during ionizing radiation-induced DNA damage response [PDF]

open access: yes, 2013
Background: After induction of DNA double strand breaks (DSBs), the DNA damage response (DDR) is activated. One of the earliest events in DDR is the phosphorylation of serine 139 on the histone variant H2AX (gH2AX) catalyzed by phosphatidylinositol 3 ...

Synthese und Eigenschaften eines neuen heterozyklischen Systems, des Imidazo[2.1-c]-as-triazins

open access: yesCHIMIA, 1969
By ring fission of 2-amino-3-phenacyl-oxazoliumhalogenides with hydrazines produces in a fast reaction the new system of 1.4-dihydroimidazo[2.1-c]-as-triazines. The reactivity and characteristic fluorescence properties of these compounds are described.

Studying DNA Double-Strand Break Repair: An Ever-Growing Toolbox [PDF]

open access: yes, 2020
To ward off against the catastrophic consequences of persistent DNA double-strand breaks (DSBs), eukaryotic cells have developed a set of complex signaling networks that detect these DNA lesions, orchestrate cell cycle checkpoints and ultimately lead to ...

Untersuchungen zum Reaktionsverhalten von N,N-disubstituierten Thioharnstoffen gegenüber Dicyanimid (DCI)

open access: yesCHIMIA, 1974
N,N-disubstituted thioureas react with dicyanimide in a simple reaction to form derivatives of the 4H-1.3.5-thiadiazine. The N,N-dimethyl-, N,N-diethyl- and N,N-di-n-propyl-thiourea react under formation of derivatives of S, S'-bis-guanyl ...

How (not) to think of the ‘dead-donor’ rule [PDF]

open access: yes, 2018
Although much has been written on the dead-donor rule in the last twenty-five years, scant attention has been paid to how it should be formulated, what its rationale is, and why it was accepted.

Über Reaktionen von Dicyanimid (DCI) mit N,N'-disubstituierten Thioharnstoffen

open access: yesCHIMIA, 1974
The reaction of dicyanimide with symmetrical disubstituted thioureas in absolute alcohol in presence of hydrogen chloride gives in good yields derivatives of the 1.3.5-thiadiazine.
