Stop Glorifying Fashion Piracy: It is Time to Enact the Innovative Design Protection Act
Get PDFThe current low-IP regime in the United States fails to provide adequate protection for fashion designs. Multiple bills had been proposed in Congress to extend copyright protection to fashion designs, but none of these was passed. Proponents of the “Piracy Paradox” doctrine suggest that unregulated copying is paradoxically beneficial to fashion designers and can foster innovation. This paper shows that the doctrine reflects a clear misunderstanding of fashion theories and how fashion trends are formed. It further argues that the fashion industry requires a diverse portfolio of inspired works rather than line-by-line knockoffs to foster trend formation. The Innovative Design Protection Act is a well-thought-out bill that can maximize the welfare of fashion designers, copyists, and the public. Congress needs to extend limited sui generis copyright protection to fashion designs that can prohibit fashion piracy without interfering with the production of inspired works
CHOREOGRAPHIC DEVICES 1
Get PDFChoreography is no longer simply the art of making dances: complex models of the choreographic are increasingly tasked to investigate and animate the intersecting spatial, corporeal, affective and informational dimensions of being entangled with the world.
What kind of choreographic arrangements can we compose to put diverse thinkers and practitioners in relation to one another? What kinds of time spaces can be plotted, imagined and enacted, when the symposium itself is choreographed and takes shape as a sequence of sessions, each brought to life by different hosts? Through contributions and interventions by over 30 international protagonists from across an expanded ecology of practices, this multi-format symposium speculates on the affordances of choreographic (re-)arrangements and their complex forms of co-production, and tests how organisational formats, material assemblages, and modes of being alongside each other, might be choreographed otherwise.
Choreographic Devices assembles contributors operating across multiple disciplinary boundaries, including Murat Adash (artist), Edwina Ashton (artist), D.

Vertical distribution of radiocesium in soil deposits on the contaminated areas after the Fukushima Daiichi Nuclear Power Plant accident
Get PDF2017 Fall.Includes bibliographical references.An accident at the Fukushima Daiichi Nuclear Power Plant (FDNPP) occurred on March 11, 2011 which resulted in an environmental contamination with the radiocesium species 134Cs and 137Cs. Vertical distribution of radiocesium is important as it impacts the area dose rate. The vertical distribution of radiocesium is sensitive to wash-off by surface runoff, wind resuspension, and soil to plant transfer. Soil core samples were extracted to develop soil profiles. The purpose of this research is to study the vertical distribution of radiocesium in different soils contaminated after the accident, and to characterize the mechanisms by which the element moves through the soil. The results were compared to data on radiocesium vertical migration observed in Fukushima contaminated area for the year 2015 (Konoplev et al. 1992; Konoplev et al. 2016). The hypothesis is that reliable predictions of future soil contamination can be made based on the results from our soil samples. Predictions regarding radiocesium movement in soils will assist and improve remediation efforts in the Fukushima District. The vertical distribution of radiocesium was found to have a rate of movement of up to 12 cm/y in fluvisol type soils of Inkyozaka, 1 cm/y in andosol soils (Funasawa) and 3 cm/y in terrestrial regosol soils (Kashiramori). The results compared well with previous studies. Movement of radiocesium in Fukushima soils is most likely due to the high precipitation rate, combined with the weak bonding of cesium to fluvisol type soils

Modificación del almidón, nanoalmidón y su aplicación en lodos de perforación
Get PDF1 recurso en línea (75 páginas) : ilustraciones color, figuras, tablas.Starch is a naturally occurring polymer with unique physicochemical properties and yet some key structural properties of starch that can be modified to meet specific requirements. The transition from starch to nano-starch and subsequent chemical modification provides a variety of benefits such as greater thermal stability and lower biodegradability. The preparation of potato starch nanoparticles (NPA) were prepared with combined methods of acid hydrolysis and sonication, after the NPA was made two modifications, a copolymer of potato starch nanoparticles grafted with polyacrylamide by free radicals, using persulfate of potassium (PSP), as initiator and carboxymethyl nano-starch of potato using potassium hydroxide as the activating agent and monochloroacetic acid as the esterifying agent, the two preparations were carried out by microwave irradiation. The true size of the nanoparticles could not be determined by SEM, because it presented agglomerations, the NPA obtained were amorphous, which indicated that the ultrasound affected the crystalline zones of the starch. The confirmation of the modification of the potato starch nanoparticles was observed by the presence of new bands in the infrared spectrum (FTIR), for the copolymer in 3191 and 1649 cm-1, the presence of the NH group and C = O respectively, and for the carboxymethyl nano-starch the presence of the carbonyl group at 1595 and 1406 cm-1. Finally, the grafted copolymer NPA-i-PAM (MCI-2) and carboxymethyl nano-starch potato (CMNPA), prepared above, were added and added to a water-based bentonite mud (8%), where an increase in viscosity was observed and decreased filtrate loss by 45 and 32% respectively, which indicated that these products could be used as additives in drilling muds as viscosifying and filtering reducing agents.El almidón es un polímero de origen natural con propiedades fisicoquímicas únicas y sin embargo, algunas propiedades estructurales claves del almidón que pueden modificarse para satisfacer requisitos específicos. El paso del almidón a nanoalmidón y posterior modificación química proporciona una variedad de beneficios como mayor estabilidad térmica y menor biodegradabilidad. La preparación de nano partículas de almidón de papa (NPA) se realizó mediante métodos combinados de hidrolisis acida y sonicación, posteriormente a las NPA se le realizaron dos modificaciones, un copolímero de nanopartículas de almidón de papa injertado con poliacrilamida mediante radicales libres, usando persulfato de potasio (PSP), como iniciador y carboximetil nanoalmidón de papa usando hidróxido de potasio como agente de activación y ácido monocloroacético como agente esterificante, las dos preparaciones se realizaron mediante irradiación de microondas. El tamaño de real de las nanopartículas no logro ser determinado por SEM, debido a que presentaba aglomeraciones, las NPA obtenidas fueron amorfas, lo que indico que el ultrasonido afecto las zonas cristalinas del almidón. La confirmación de la modificación de las nanopartículas de almidón de papa se observó mediante la presencia de nuevas bandas en el espectro infrarrojo (FTIR), para el copolimero en 3191 y 1649 cm-1, la presencia del grupo N-H y C=O respectivamente, y para el carboximetil nanoalmidón la presencia del grupo carbonilo en 1595 y 1406 cm-1. Finalmente se tomo el copolimero injertado NPA-i-PAM (MCI-2) y carboximetil nanoalmidón de papa (CMNPA), preparados anteriormente y se añadieron a un lodo bentonita base agua (8%), donde se observó un aumento en la viscosidad y disminuyo la perdida de filtrado en un 45 y 32 % respectivamente, lo que indicaron que estos productos podrán ser utilizados como aditivos en los lodos de perforación como agentes viscosificantes y reductores de filtrado.Bibliografía: páginas 70-74.MaestríaMagíster en Químic
Variación espacial de las concentraciones de PM10 Y PM2.5 en las principales vías de la ciudad de Barranquilla
Get PDFUrban atmospheric particulate material (PM) is a highly important pollutant due to the effects it generates on people's health and the environment. The presence of PM in urban areas varies spatially, so high or low concentrations can be found in different areas of the same city. In this study, a HAL-HPC601 particle counter and a Garmin Oregon 350 GPS were used at a height of 1.60 m in the execution of mobile monitoring to understand the dynamics of the particulate matter and identify hot spots on the main roads of the city of Barranquilla, 9 mobile monitoring were carried out in the months of July and August 2019, carried out on business days between 2:00 p.m. and 5:00 p.m. with a total distance traveled of 35.9 km, obtaining highresolution maps of the PM10 and PM2.5 concentrations along the monitoring route (Vía 40, Calle 30 and Avenida Circunvalar) to represent the spatial variability of PM concentrations. In concentration data analysis, outliers were identified through standard deviation analysis. The results show that the points with the highest concentration of PM10 and PM2.5 were recorded in Calle 30, an area with high traffic congestion, with average concentration results of 68.49 ± 54.28 µg / m3 for PM10 and 16, 66 ± 4.19 µg / m3 for PM2.5. This section of the road has the largest number of traffic lights and photo detection cameras. Particulate matter tends to concentrate on stretches of high-traffic roads in close proximity to likely sources, such as intersections, pedestrian crossings, slow-speed roads, and areas of vehicular congestion. Commercial and industrial areas are associated with high concentrations of particulate matter, it is likely that they are the result of the report in the set of fixed and mobile sources. However, since all the sampling was carried out on public roads, and very close to the source, some high measurements are attributed to traffic congestion and heavy vehicles.El material particulado atmosférico (PM) urbano es un contaminante de gran importancia por las afectaciones que genera a la salud de las personas y al medioambiente. La presencia del PM en zonas urbanas varia espacialmente, por lo que pueden encontrarse altas o bajas concentraciones en diferentes zonas de una misma ciudad. En este estudio, se utilizó un contador de partículas HAL-HPC601 y un GPS Garmin Oregón 350 a una altura de 1,60 m en la ejecución de monitoreos móviles para comprender la dinámica del material particulado e identificar puntos calientes en las principales vías de la ciudad de Barranquilla, fueron realizados 9 monitoreos móviles en los meses de julio y agosto de 2019, realizados en días hábiles entre las 14:00 y 17:00 horas con una distancia total recorrida de 35,9 km obteniendo mapas de alta resolución de las concentraciones de PM10 y PM2.5 a lo largo de la ruta de monitoreo (Vía 40, Calle 30 y Avenida Circunvalar) para representar la variabilidad espacial de las concentraciones de PM. En el análisis de los datos de concentración, se identificaron los datos atípicos a través del análisis de la desviación estándar. Los resultados evidencian que los puntos con mayor concentración de PM10 y PM2.5 fueron registrados en la Calle 30, zona con alta congestión vehicular, con resultados promedios de concentración de 68,49 ±54,28 µg/m3 para el PM10 y de 16,66 ±4,19 µg/m3 para el PM2.5. Este tramo de la vía posee el mayor número de semáforos y cámaras de foto detección. El material particulado tiende a concentrarse en los tramos de carreteras con mucho tráfico en las proximidades a fuentes probables, como intersecciones, cruce de peatones, vías con baja velocidad y sectores de congestión vehicular. Las zonas comerciales e industriales se relacionan con altas concentraciones de material particulado, es probable que sean el resultado del aporte en conjunto de fuentes fijas y móviles. Sin embargo, dado que todo el muestreo se realizó en vías públicas, y muy cercano a la fuente, algunas mediciones altas se atribuyen a la congestión vehicular y los vehículos pesados
