However, the procedure carries the dual risk of air (pneumothorax) or blood (hemothorax) filling the pleural cavity, increasing the risk of a collapsed lung and chest intubation. This work demonstrates the effectiveness of a polyurethane-based shape memory polymer foam as a biopsy tract sealant. The impact of diameter, length, pore size, and shape memory effect was evaluated to determine the ideal device design for tract sealing. Characterization in an in vitro benchtop lung model identified that diameter had the largest influence on sealing efficacy, while the length of the device had little to no impact. Finally, evaluation of deployment force demonstrated that devices fabricated from the shape memory polymer foams were easier to deploy than elastic foams. Following characterization, down-selected device designs were combined with radiopaque markers for use in image-guided based procedures. Furthermore, the introduction of the markers or sterilization did not impact the ability of the devices to seal the biopsy tract and led to a decrease in the deployment force. Overall, these results demonstrate the potential for polyurethane-based shape memory foam devices to serve as biopsy tract sealant devices that aim to reduce complications, such as pneumothorax, from occurring.","PeriodicalId":17968,"journal":{"name":"Latin American Antiquity","volume":"29 1","pages":"853-860"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10732340/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75417145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Former Jesuit vineyards with two of the largest enslaved African-descended populations in rural coastal Peru—the haciendas of San Joseph (San José) and San Francisco Xavier (San Javier)—and their annexes in Nasca's Ingenio Valley underwent dramatic transformations with the replacement of their grapevines with cotton and the introduction of new types of workers. Cantonese indentured workers were contracted beginning in the 1830s, and the majority-enslaved workforce was legally emancipated in 1854. Seasonally, highland Andean workers joined the demographically shifting permanent hacienda population. We use evidence from excavated midden contexts at San Joseph, San Xavier, and San Joseph's annex of Hacienda La Ventilla to explore these changing agroindustrial dynamics and worker well-being in the eighteenth and nineteenth centuries. Despite the transformations at the estates, we find that culinary practices developed by enslaved Africans and their descendants during the Jesuit administration, such as the preparation of one-pot meals and stews, continued into the republican era among Cantonese indentured laborers and wage workers of Indigenous, mestizo, and Cantonese origins. We argue that such strategies centered on foodways were a crucial aspect of worker self-care regimes and broader well-being.","PeriodicalId":17968,"journal":{"name":"Latin American Antiquity","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46016338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Este trabajo evalúa la variable intensidad en la ocupación humana en Laguna del Diamante en cinco segmentos temporales entre 2030 y 440 años cal aP. Estos segmentos se modelaron a partir de 14 fechados radiocarbónicos procedentes de tres sitios; la densidad de lascas proximales se evalúa como proxy de intensidad de ocupación. Se comparan los pulsos registrados arqueológicamente con la variabilidad ambiental vinculada a aumento/disminución de temperatura y humedad, de los últimos milenios en tres lagunas: Aculeo, Chepical y del Maule (33°-35°S). A partir de diversos indicadores —cobertura vegetal, extensión/disminución de la cubierta de hielo, cambios de la precipitación relacionados al sistema de vientos del oeste y su variabilidad debido a El Niño Oscilación del Sur— se observó en casi toda la secuencia una asociación positiva entre condiciones favorables y ocupaciones intensas. Se discute el registro de dos pulsos de mayor intensidad: entre 1200 y 1280 años cal aP, asociado con aumento de temperatura de verano e intensificación de precipitaciones; y entre 450 y 500 años cal aP, vinculado con condiciones frías y coincidente con la presencia incaica en el área.","PeriodicalId":17968,"journal":{"name":"Latin American Antiquity","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"56993242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
