Radon gas. Environmental concentration measures and remediation actions in exposed buildings

The main contribution to the radiological impact from natural radiation received by general population is due to the emission of radon (222Rn). The objective of this project is the study of radon gas as a radioactive element in our buildings (existing and future constructions) to avoid its influence in interior rooms. The proposed methodology reflects different aspects of natural radioactivity in buildings, their sources, their control criteria and regulatory framework; aspects related to the presence of radon in our constructions, entryways, measurement methodology for indoor environmental concentration are studied; other protection solutions and remediation measures in both existing buildings and new construction projects are analyzed. In conclusion, the paper presents previous evaluation tools, the analysis of existing concentration and the choice of the most appropriate mitigation / remediation measures depending on each case, through the establishment of different architectural proposals to plan actions against radon where necessary.

La aplicación de stop-motion en arquitectura: materia y luz

Se inicia un análisis de los procesos de trabajo de stop-motion porque ayudan a comprender las diferentes escalas en arquitectura donde las maquetas se convierten en futuros prototipos de infraestructuras de edificios o de paisaje. Stop motion es una técnica de animación fotograma a fotograma de objetos estáticos mediante la manipulación de figuras de plastilina en entornos fijos con cambios de luz, color y sonido. Igual que dicha técnica reúne lo mejor del rodaje tradicional -story board, escenografía, fotografía, personajes, iluminación- la animación de maquetas de interiores sintetiza micro-procesos de mayor repercusión -habitaciones con cambios de humedad, de temperatura, de ventilación y de iluminación- incorporando efectos especiales que son procesados digitalmente en post-producción. Se construyen varios prototipos de habitación con parámetros fijos como el tamaño y la posición de la cámara y otros variables como los materiales, los personajes y la iluminación. Representan un mundo en miniatura que intenta aportar un acercamiento sensorial y atmosférico analizando la magia y la fantasía que Junichirô Tanizaki describe en la penumbra de las construcciones tradicionales japonesas y estudiando las imperfecciones de los escenarios que Tim Burton manipula en su películas de animación con una textura que las tecnologías digitales no pueden igualar. El objetivo es utilizar una escala micro para realizar unos modelos interiores donde las condiciones atmosféricas están controladas y reducidas, y tomar datos que se podrían aplicar a un proceso de modelado a escala intermedia para testar prototipos de edificios como el túnel de viento; o, finalmente, a una escala macro con maquetas de un sector de la costa o de un río donde los fenómenos meteorológicos son los protagonistas para simular inundaciones y diseñar futuras medidas de prevención y seguridad.

III. Diary, 1799

This diary, which John Henry Tudor titled A Registry of College Adventures, documents his life as a student at Harvard College. The entries describe his daily activities and notable events, including trips to the theater, hunting outings to "shoot Robbins," adventures with other students in local taverns, visits with his family in Boston and at the family estate, Rockwood, and the illumination of Cambridge in honor of George Washington's birthday. Tudor created and recorded a humorous classology, describing his peers at Harvard in a sometimes scathing manner, and also recorded information about those obliged to leave the College, usually following pranks or other unacceptable behavior. He also recounts his own involvement in pranks and other antics, which he believed to be the only antidote to the dullness of college life, and in one entry he describes an evening when he and several friends "disguised [them]selves like Negroes" and wandered into scholars' rooms without detection. Tudor was a member of the Hasty Pudding Club and the Porcellian Club ("the Pig club") while at Harvard and describes club meetings in several entries. There are also more reflective and personal entries, describing Tudor's feelings about his aging grandmother, his brother William's departure for Holland, and his desire for a "wife who shall make [him] happy[,] an affectionate dog [and] a farm & garden."

Draft of law related to the settling of chambers after Commencement, 1742

One-page handwritten draft of a law created by the president and tutors requiring juniors to inform the Faculty of their intent to stay in dormitory rooms following Commencement. The document is undated and unsigned, but appears to be in the hand of President Edward Holyoke, and has a note in shorthand in the left margin. The text is included in College Book IV and was presented at a meeting of the Harvard Corporation on September 6, 1742.

Front elevation and floor plans for first and second floors, ink and wash on paper, [ca. 1812]

Drawing by Charles Bulfinch of proposed plans for University Hall which were later rejected. Includes sketches of the front exterior view of the University Hall, and separate floor plans for the ground and second floors. Bulfinch designed a ground floor with a chapel and four dining halls each holding 100 students, a second floor with a gallery in the chapel and three rooms over the dining halls for public examinations and meetings of the Corporation and Overseers; and a basement under the halls intended for a kitchen under the dining halls and recitation rooms under the chapel.

Sketchbook contains four drawings of elevations and floor plans of University Hall. Includes floor plans for the ground floor and second story. Also contains exterior sketches of side view and end view and principal entrance. Each drawing is accompanied by notes indicating the scales measurements and designated rooms in Floor plan sketches.
