Using Google Tag Manager for embed codes on blog – how?

Hi,

I want to learn Google Tag Manager for placing codes on my rebuilt site. The types of codes I want to include are the typical copy-paste and embed codes like:
– Google Analytics
– Add This (social bookmarking icons appearing above the article)
– Disqus (commenting system)
– …potentially others as well

My dilemma is:

I know that Google Tag Manager can include sitewide codes (like: everywhere on the site), such as Google Analytics, which are invisible anyway. But: can I chose where a…

Does every sheaf embed into a quasicoherent sheaf?

Question. Let $ X$ be a scheme. Let $ \mathcal{E}$ be a sheaf of $ \mathcal{O}_X$ -modules. Is there always a quasicoherent sheaf $ \mathcal{E}’$ together with a monomorphism $ \mathcal{E} \to \mathcal{E}’$ ?

Remark. The coherator yields a way to find a quasicoherent sheaf together with a morphism to $ \mathcal{E}$ . But I’m interested in finding a quasicoherent sheaf together with a monomorphism from $ \mathcal{E}$ .

Motivation. There is a way to set up the theory of sheaf cohomology for quasicoherent sheaves without injective or flabby resolutions. If any sheaf of modules would embed into a quasicoherent one, we might be able to extend this development to arbitrary (not necessarily quasicoherent) sheaves of modules.
