Analysis of Ties, Tie Systems, and Attachment Methods of Fibrous Sandals of Tsegi Phase (Pueblo III) Kayenta Branch, from Tsegi Canyon, Arizona

Christensen, Diana Law 01 May 1993 (has links)
Forty-three Pueblo III sandals and sandal fragments from four sites in Tsegi Canyon, Arizona, were analyzed to develop tie terminology, identify possible correlation of tie system to sandal construction, and identify characteristics for future tie research. Each piece of sandal tie cordage was analyzed for tie system type, tie attachment method, and tie cordage structure. Three overall tie systems were found: toe-heel tie systems (nine sandals), criss-cross tie system (one sandal), and side loop tie systems (fifteen sandals) Five additional sandals (narrow, two-warp plainweave construction) had possible toe-heel tie systems. Tie systems of six sandals were not distinguishable between toe-heel and criss-cross. Five sandals had unidentifiable tie fragments, and two sandals had no tie information. Terminology had to be developed for several tie components. Toe loops were found with a single loop (either intact or tied over the toe) and multiple loops (overlapping, adjacent, or parallel). Side loops were overlapping (continuous, mirror image, or reversing), adjacent, and parallel. Ankle/heel loops included single, double, and double intertwined horizontal loops (back of heel), and two vertical loops (side of heel). Loop variations for two-warp plainweave were through weft, around weft, flat loop, and upright loop. Numerous attachment methods were used for the toe, ankle/heel, and side loops, including sole knots and running stitches. Tie materials included four constructions of leaf: unprocessed leaf, S-twist leaf, Z-twist leaf, and plied leaf (Z-2S, S-2Z, Z-3S). Twelve constructions of yarn were identified, including two- and three-ply yarns of various twist combinations, re-plied yarn, and splicing. Toe-heel and criss-cross tie system sandals tended to have only one cordage type used on an individual sandal; side loop system sandals tended to have several cordage types used on an individual sandal. A comparison of tie system and sandal construction methods revealed that coarse-braided and two-warp plainweave sandals more frequently used the toe-heel system. Fine-braided and four-and five-warp plainweave sandals used the toe-heel and side loop systems nearly evenly. Markers for future tie researchers to examine include number of toe loops, types and attachment methods of toe and side loops, and style variations and attachments of ankle/heel loops.

No. of bitstreams: 1 Paulo Ricardo da Silva.pdf: 2807070 bytes, checksum: a396ead3497c7e6defcd09112e6c5043 (MD5) Previous issue date: 2015-07-17 / ] The species of stingless bee Melipona mandacaia is popularly known as mandaçaia and is native to northeastern Brazil. This study analyzed honey and geopropolis of mandaçaia. For honey were carried out pollen, physical and chemical analysis such as moisture, pH, free acidity, hydroxymethylfurfural, ash content, reducing sugars and water activity, amino acids, minerals and antiradical activity of four samples of honey. The major phenolic constituents of honey were extracted and analyzed by High Performance Liquid Chromatography Efficiency coupled to the Diode Array Detector (HPLC-DAD). Pollen analysis showed that the dominant pollen in honey samples was the plant species Mimosa arenosa (Fabaceae / Mimosoideae) ranging from 44.4% to 61.7%. The identified flavonoids quercetin, luteolin, and kaempferol acid derivatives: 3,4-dihydroxybenzoic, 1,2-dihydroxybenzoic, caffeic, cinnamic and ferulic were quantified. All honey samples showed the amino acid proline, alanine, serine and threonine. The minerals were the predominant calcium and potassium. All honeys showed scavenging activity of free radical front to DPPH and ABTS. For geopropolis of mandaçaia was determined to botanical origin, phenolics were quantified by HPLC-DAD and the antioxidant activity was determined by testing with DPPH, ABTS and beta carotene / linoleic acid system. Pollen analysis of nine samples geopropolis showed the presence of 25 types of pollen representing fifteen families. The Senna species (Leguminoseae) was the predominant pollen in eight of the nine samples. The phenol content in the geopropolis of mandaçaia were identified as caffeic acid, coumaric acid, trans-3-hydroxycinnamic acid, 4-methoxycinnamic acid and abscisic. All samples geopropolis showed antioxidant activity, except hexanic fractions that have been inactive for the free radical DPPH. / A espécie de abelha sem ferrão Melipona mandacaia é conhecida popularmente como mandaçaia e é nativa do Nordeste brasileiro. Neste estudo foi analisado o mel e a geoprópolis da mandaçaia. Foram realizadas as análises palinológicas, físico-químicas tais como umidade, pH, acidez livre, hidroximetilfurfural, teor de cinzas, açucares redutores e atividade de água, aminoácidos, minerais e atividade antirradicalar em quatro amostras de mel. Os principais constituintes fenólicos do mel foram extraídos e analisados por Cromatografia Líquida de Alta Eficiência acoplada ao Detector de Arranjo de Diodos (CLAE-DAD). A análise palinológica mostrou que o pólen predominante nas amostras de mel foi da espécie vegetal Mimosa arenosa (Fabaceae/Mimosoideae), variando de 44,4% a 61,7%. Os flavonoides identificados quercetina, luteolina, kampferol e os derivados de ácido: 3,4-dihidroxibenzoico, 1,2-dihidroxibenzoico, cafeico, cinâmico e ferúlico foram quantificados. Todas as amostras de mel apresentaram os aminoácidos prolina, alanina, serina e treonina. Os minerais predominantes foram o cálcio e potássio. Todos os méis apresentaram atividade sequestradora de radical livre frente ao DPPH e ABTS. A origem botânica da geoprópolis da mandaçaia foi determinada e os compostos fenólicos foram quantificados por CLAE-DAD e a atividade antioxidante foi determinada pelos testes com DPPH, ABTS e o sistema beta caroteno/ácido linoleico. A análise palinológica das nove amostras de geoprópolis mostraram a presença de 25 tipos de pólen representando quinze famílias. O tipo polínico Senna (Leguminoseae) foi o predominante em oito das nove amostras analisadas. Os fenólicos presentes na geoprópolis da mandaçaia foram identificados como sendo ácidos cafeico, cumárico, trans-3-hidroxicinâmico, abscísico e 4-metoxicinâmico. Todas as amostras de geoprópolis apresentaram atividade antioxidante, exceto as frações hexânicas que foram inativas para o radical livre DPPH.
