Oláh
"Vlach" ( or ), also "Wallachian" (and many other variants), is a historical term and exonym used from the Middle Ages until the Modern Era to designate mainly Romanians but also Aromanians, Megleno-Romanians, Istro-Romanians and other Eastern Romance-speaking subgroups of Central and Eastern Europe. As a contemporary term, in the English language, the Vlachs are the Balkan Romance-speaking peoples who live south of the Danube in what are now southern Albania, Bulgaria, northern Greece, North Macedonia, and eastern Serbia as native ethnic groups, such as the Aromanians, Megleno-Romanians and the Timok Romanians. The term also became a synonym in the Balkans for the social category of shepherds, and was also used for non-Romance-speaking peoples, in recent times in the western Balkans derogatively. The term is also used to refer to the ethnographic group of Moravian Vlachs who speak a Slavic language but originate from Romanians. "Vlachs" were initially identified and des ...

In Europe, Romanian is rated as a medium level language, occupying the tenth position among thirty-seven official languages.

To distinguish it within the Eastern Romance languages, in comparative linguistics it is called '' Daco-Romanian'' as opposed to its closest ...

Korban Olah
A burnt offering in Judaism ( he, קָרְבַּן עוֹלָה, ''qorban ʿōlā'') is a form of sacrifice first described in the Hebrew Bible. As a tribute to God, a burnt offering was ''entirely'' burnt on the altar. This is in contrast to other forms of sacrifice (entitled ''zevach'' or ''zevach shelamim''), which was ''partly'' burnt and ''most'' of it eaten in communion at a sacrificial meal. During the First Temple and Second Temple periods, the burnt offering was a twice-daily animal sacrifice offered on the altar in the temple in Jerusalem that was completely consumed by fire. The skin of the animal, however, was not burnt but given to the priests respective of their priestly division. These skins are listed as one of the twenty-four priestly gifts in Tosefta Hallah.

It is structurally related to benzene, with one methine group replaced by a nitrogen atom. It is a highly flammable, weakly alkaline, water-miscible liquid with a ...; alcohols react with this reagent to give alkyl fluorides: It acts as a stabilized, less volatile form of hydrogen fluoride. It is used in the fluorination of steroids and in deprotection of peptides.Review of use in organic synthesis: G. A. Olah et al., J. Fluorine Chem. 33, 377–396 (1986). Instead of hydrogen fluoride, several other fluorinating agents can be used, such as diethylaminosulfur trifluoride (DAST).

He was also awarded the Priestley Medal, the highest honor granted by the American Chemical Society and F.A. Cotton Medal for Excellence in Chemical Research of the American Chemical Society in 1996. After the Hungarian Revolution of 1956, he emigrated to the United Kingdom, which he left for Canada in 1964, finally resettling in the United States in 1965.
