Encyclopaedia of Scientific Units, Weights and Measures Their SI Equivalences and Origins
FrancËois Cardarelli Encyclopaedia of Scientific Units, Weights and Measures Their SI Equivalences and Origins English translation by M.J. Shields, FIInfSc, MITI 13 Other Systems 3 of Units Despite the internationalization of SI units, and the fact that other units are actually forbidden by law in France and other countries, there are still some older or parallel systems remaining in use in several areas of science and technology. Before presenting conversion tables for them, it is important to put these systems into their initial context. A brief review of systems is given ranging from the ancient and obsolete (e.g. Egyptian, Greek, Roman, Old French) to the relatively modern and still in use (e.g. UK imperial, US customary, cgs, FPS), since a general knowledge of these systems can be useful in conversion calculations. Most of the ancient systems are now totally obsolete, and are included for general or historical interest. 3.1 MTS, MKpS, MKSA 3.1.1 The MKpS System The former system of units referred to by the international abbreviations MKpS, MKfS, or MKS (derived from the French titles meÁtre-kilogramme-poids-seconde or meÁtre-kilo- gramme-force-seconde) was in fact entitled SysteÁme des MeÂcaniciens (Mechanical Engi- neers' System). It was based on three fundamental units, the metre, the second, and a weight unit, the kilogram-force. This had the basic fault of being dependent on the acceleration due to gravity g, which varies on different parts of the Earth, so that the unit could not be given a general definition. Furthermore, because of the lack of a unit of mass, it was difficult, if not impossible to draw a distinction between weight, or force, and mass (see also 3.4). -
Tzeltal Ethnomycology: Naming, Classification and Use Of
TZELTAL ETHNOMYCOLOGY: NAMING, CLASSIFICATION AND USE OF MUSHROOMS IN THE HIGHLANDS OF CHIAPAS, MEXICO by AARON MICHAEL LAMPMAN (Under the Direction of Brent Berlin) ABSTRACT The Tzeltal Maya of Highland Chiapas have extensive knowledge of wild mushrooms in the local ecosystem. This dissertation examines the totality of Tzeltal ethnomycological knowledge through an analysis of patterns of nomenclature and classification, knowledge of mushroom ecology, and beliefs about mushroom nutritional, medicinal, and toxic properties. Research was conducted in communities in the municipalities of Oxchuc and Tenejapa. Methods included mycological collection, semi- structured interviews, pile sorts, triad tests, sentence substitution surveys and participant observation. The explanatory approach is ethnoecological, with a focus on the interaction between human cognition and domain features and how this interaction influences behavior. A total of 72 species were identified and are described herein. Of these, 30 species are utilized for food and medicine. The mushroom domain is perceived as a third kingdom that is independent of the plant and animal kingdoms. The kingdom includes two life-forms that are further subdivided into 4 covert complexes, and 51 folk genera, 4 of which are polytypic and include between 2 and 5 folk species. These categories are based on morphological similarities and dissimilarities, supporting the universal principles of folk classification as proposed by Berlin (1992). However, unique features of the mushroom domain such as small size, morphological similarity and toxicity make the use of mushrooms potentially dangerous. The Tzeltal deal with these features through the recognition of two special purpose folk categories based on utility that overlap and interact with the general purpose system of folk classification. -

Manuscripts & Special Collections Weights and Measures
Introduction - Weights and Measures - Skills Resources - Manuscripts & Special Collections- The University of Nottingham Manuscripts & Special Collections Weights and measures Deciphering units of weights, measurements, and money in historical documents can cause problems for researchers. Virtually every unit of measurement used up to the mid-twentieth century has now been replaced, or is being replaced, by decimal or metric measurements. A few old measurements are still in current use in the UK, such as pints and miles, but most people will now need to consult reference works in order to understand the measurements used in the past. The information provided within this skills unit aims to identify and explain some of the most common difficulties and pitfalls and to provide sources of assistance. It is concerned only with English and Welsh measurements. Researchers should check specialist publications and the Scottish Archives Network (SCAN) Weights and Measures Guide for information on Scottish measurements. Standardisation of weights and measures in England and Wales was a long and complicated process. The measurements referred to here are predominantly those used from the late sixteenth and early 17th centuries onwards, and those in force after the Weights and Measures Act of 1824. For medieval and earlier measurements, researchers should consult specialist Engraving of a pair of scales in a shop, from The Child's works. Arithmetic: A Manual of Instruction for the Nursery and Infant Schools (London: William S. Orr and Co., 1837) Imperial and Metric measurements Imperial measurements were derived from the measurements used by the Romans. Over time, measurements used by different countries began to vary. -
