Åsen is a village and former municipality in Nord-Trøndelag county, Norway. The former municipality constitutes the southern part of the present-day municipality of Levanger, bordering Stjørdal to the south.
The village of Åsen is located along the European route E6 highway and the Nordlandsbanen railway line with the Åsen Station. The village sits between the lakes Hammervatnet and Hoklingen. It is home to the Åsen Church. The 0.52-square-kilometre (130-acre) village has a population (2013) of 593. The population density is 1,140 inhabitants per square kilometre (3,000/sq mi).
The municipality of Aasen was established on 1 January 1838 (see formannskapsdistrikt). The spelling was later changed to Åsen. On 1 January 1962, Åsen was merged with Frol, Levanger, and Skogn to form a new, larger Levanger municipality. Prior to the merger, Åsen had a population of 1,939.
Thailand adopted the metric system on 17 December 1923. However, old Thai units are still in common use, especially for measurements of land.
Before metrication, the traditional system of measurement used in Thailand employed anthropic units. Some of these units are still in use, albeit standardised to SI/metric measurements. When the Royal Thai Survey Department began cadastral survey in 1896, Director R. W. Giblin, F.R.G.S., noted, "It so happens that 40 metres or 4,000 centimetres are equal to one sen," so all cadastral plans are plotted, drawn, and printed to a scale of 1:4,000. The square wa, ngan and rai are still used in measurements of land area.
The baht is still used as a unit of measurement in gold trading. However, one baht of 96.5% gold bullion is defined as 15.16 grams rather than the generic standard of 15 grams. The baht has also become the name of the currency of Thailand, which was originally fixed to the corresponding mass of silver.
The USGS DEM standard is a geospatial file format developed by the United States Geological Survey for storing a raster-based digital elevation model. It is an open standard, and is used throughout the world. It has been superseded by the USGS's own SDTS format but the format remains popular due to large numbers of legacy files, self-containment, relatively simple field structure and broad, mature software support.
A USGS DEM can be classified into one of four levels of quality. This is due to the multiple methods of data collection, and certainty in the data.
The USGS DEM format is a self-contained (single file) set of ASCII-encoded (text) 1024-byte (1024 ASCII chars) blocks that fall into three record categories called A, B, and C. There is no cross-platform ambiguity since line ending control codes are not used, and all data including numbers is represented in readable text form. There is no known binary analogue of the format, although it is common practice to compress the files with gzip.
Demai (Hebrew: דמאי) is the third tractate of Seder Zeraim ("Order of Seeds") of the Mishnah and of the Talmud. There is some debate as to the literal meaning and origin of the word. It is concerned mainly with laws related to produce where it is suspected that ma'aser rishon (the first tithe for the Levi), terumat ma'aser and ma'aser sheini (the second tithe) or ma'aser ani (the tithe for the poor), depending on the year of the Shemittah cycle, have not been properly separated in accordance with Num. 18:24-28. It consists of seven chapters and has a Gemara from only the Jerusalem Talmud.
DEM was the ISO 4217 currency code for the Deutsche Mark, former currency of Germany.
