Sesenta y cinco años después, este artículo recoge imágenes inéditas de ese mismo espacio tomadas durante una visita a la cubierta realizada durante el período de ejecución del plan de rehabilitación de Notre-Dame du Haut llevado a cabo entre los años 2022 y 2024. Con el fin de analizar el vacío comprendido entre las dos láminas de hormigón que conforman la cubierta, así como la relación que establece dicho vacío tanto con los espacios interiores de la capilla como con el paisaje exterior, la reflexión teórica que acompaña a las imágenes aportadas se sirve de la metáfora como herramienta para su desarrollo, permitiendo así que el lenguaje preserve la naturaleza sugestiva de este espacio oculto. Siguiendo esta premisa, los elementos arquitectónicos reconocibles en la cubierta de la capilla —trampillas, huecos de ventilación, chimeneas, vigas o pasos de mantenimiento— se transforman en los órganos de la anatomía de una ballena. La exploración de estos elementos desvela la forma en la que en el envés oculto de Ronchamp también reside la obra de arte.","PeriodicalId":49915,"journal":{"name":"LC GC Europe","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135198936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photodiode array (PDA) and mass spectrophotometric (MS) detection was necessary to facilitate peak tracking or identification of components in the sample mixture to build retention models. Retention time prediction accuracies of < 0.3% were obtained from a two-dimensional gradient time vs. temperature model when the initial gradient conditions were maintained. However, anomalous retention predictions were observed when higher %B initial gradient conditions were employed. Polar analytes in the sample mixture that started to migrate down the column in the dwell volume of the UHPLC system produced inaccurate retention time predictions if an inappropriate dwell volume was used in the retention model. An iterative dwell volume estimation was demonstrated to generate more accurate retention time predictions than when a practically determined dwell volume was used. However, to obtain good predictions the analyst should endeavour to use initial chromatographic conditions that promote focusing of all analytes on top of the column (that is, retention factor > 10).","PeriodicalId":49915,"journal":{"name":"LC GC Europe","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135349000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
