A Scoping Study to Develop a Computational Fluid Dynamics Based Model to Predict Radiological Materials Packaging Temperatures within a Generic Staging Building

The objective of this work is to perform computational fluid dynamics simulations of a ventilated radiological-material-package staging building to determine the effect of including or excluding a variety of physical effects and computational methods on both the predicted package temperatures and required computational resources. The generic building contains 640 drum-packages containing heat-generating, radiological material supported on four racks that are eight levels tall. Additionally, there is a forced ventilation system, lighting, and insulated walls. Computational models were constructed that included or excluded (a) shelving, (b) effects of unsteadiness, and (c) radiation heat transfer. Simulations with each drum modeled separately were compared to simpler simulations with sets of four drums represented by an equivalent box-package. These models employed between 106 to 107 elements.Steady state simulations predicted package temperatures that were within 0.1°C of simulations that included transient effects and required only one-eighth the computational resources. Calculations that excluded shelving predicted temperatures within 0.6°C of simulations that included shelving and required one-fourth the computational resources. Excluding radiation heat transfer systematically increased temperatures by around 1.5°C but reduced computational resources by a factor of four. The box-package model reduced the computational resources by a factor of 3, but systematically predicted higher temperatures by around 1.1°C. These results will be used to develop an efficient computational fluid dynamics model to assess the ability of different staging building designs to prevent the temperature of package components from exceeding specified limits

Sky well

Since the era of Romanticism, landscape painting has fallen into three aesthetic forms of representation: the Pastoral, the Picturesque, and the Sublime. This last form celebrates the awe and fear that arises through human encounters with nature. Many contemporary critics dismiss the Natural Sublime, claiming either that technology has replaced nature as a source of the sublime, or that humankind’s present-day destruction of nature prevents our also standing in awe of it. I disagree with both arguments. To me, humanity’s disruption of Earth’s ecosystems does not impede an individual’s experience of exhilaration witnessing, say, a volcanic eruption. And modern technology has deepened our knowledge of nature—from the tiniest subatomic particles to the vast recesses of outer space—giving us countless new occasions for reverence. My work is a reinterpretation of the genre of landscape and the Natural Sublime. Though they appear representational, the works are actually highly abstracted spaces, devoid of spatial perspective. They also move away from the traditional picture plane as a framing device, and embrace ephemerality in both material and method. My newest works navigate between two spaces—the near and the far—and between two scales—the micro and the macro. They invite the viewer to move between a sense of visual stillness and one of motion. And by compressing disparate images (the night sky and the stony ground) into a single visual space, they offer a simultaneous experience of the temporal and the infinite. My work has a strong sense of tactility and has obviously been touched by hand many times. These works embody ideas about the ephemeral nature of existence, and the presence of the artist’s hand is meant to make these abstractions more accessible. The works are also highly detailed and evidence considerable labor, suggesting by analogy the time it has taken for the objects depicted—these stars and stones—to come into being. Meticulous hand work is complemented by the use of printmaking to create, through an indirect process, the highly varied texture and detail one sees in natural surfaces. My use of printmaking mimics nature in another way: each plate is printed just once; like a leaf, each print is a unique mark. My imagery explores objects we regard as permanent but are not, and this temporal quality is reflected in how my drawings are made. My work strives for the presence and visual weight of an object: I create an enveloping dark density in my drawings, which on a large scale, creates a kind of monument to nature. Along with this stately presence is a fragility and temporality embodied in the materials, in particular my use of paper. I am also experimenting with work that is ephemeral in that it is site-determined but not permanent, changing as it is installed in other sites. Through its immense scale, ephemerality, and lack of visual spatial perspective, my work separates itself from the aesthetics of pastoral and picturesque categories of landscape painting to participate in the contemporary conversation about representation, abstraction, and materiality, and to reinterpret the subject of the Natural Sublime in painting

Bistriopelma, un género nuevo con dos nuevas especies de Perú (Araneae: Theraphosidae: Theraphosinae)

Bistriopelma gen. nov. from the Andean region in Peru is here described, diagnosed and illustrated, together with two new species Bistriopelma lamasi sp. nov. as a type species and Bistriopelma matuskai sp. nov. This new genus differs from all other theraphosid genera, except the genus Phrixotrichus Simon 1889 (sensu Perafán & Pérez-Miles 2014) and the troglobite species Tmesiphantes hypogeus Bertani, Bichuette & Pedroso 2013, in the presence of two abdominal dorsolateral patches of the type III urticating setae. Bistriopelma gen nov. can be distiguished from Phrixotrichus by the different shape of spermathecae in females, consisting of two separate subparallel seminal receptacles in Bistriopelma gen. nov. but strongly divergent in Phrixotrichus and by the different morphology of male palpal bulb (embolus projecting retrolaterally from tegulum in Bistriopelma gen. nov. against posteriorly in Phrixotrichus); furthermore by the presence of basal spine on prolateral tibial apophysis, the absence of the type IV urticating setae and paired tarsal claws denticulate. Bistriopelma gen. nov. is separated from Tmesiphantes hypogeus by the position of the urticating seta patches (middle of abdomen in Bistriopelma gen. nov. and posterior half in Tmesiphantes hypogeus), the different shape of spermathecae (long separate seminal receptacles with subapical constriction in Bistriopelma gen. nov. and short, subtriangular and widely separated in Tmesiphantes hypogeus) and also in the extension of metatarsal scopulae. Additional comments and a distribution map of all species of this genus are provided.Se describe, diagnostica e ilustra Bistriopelma gen. nov. de la región andina de Perú, con dos nuevas especies Bistriopelma lamasi sp. nov., especie tipo, y Bistriopelma matuskai sp. nov.

Bistriopelma gen nov. se diferencia de Phrixotrichus en la morfología de la espermateca, estando compuesta en Bistriopelma gen. nov. de dos receptaculos seminales separados y subparalelos pero considerablemente divergentes en Phrixotrichus, en la morfología de los bulbos pedipalpales de machos (émbolo proyectándose retrolateralmente del tegulum en Bistriopelma gen. nov. contra posteriormente en Phrixotrichus); además en la presencia de la espina basal en la apófisis tibial prolateral, en la ausencia de las setas urticantes de tipo IV y en las uñas tarsales con dientes. Se diferencia de Tmesiphantes hypogeus en la posición de los parches de las setas urticantes (centro del abdomen en Bistriopelma gen. nov. y parte posterior en Tmesiphantes hypogeus), en la morfología de las espermatecas (receptáculos seminales prolongados y separados, subapicalmente estrechados en Bistriopelma gen. nov. y cortos, subtriangulares y considerablemente separados en Tmesiphantes hypogeus) y también en la extensión de las escopulas metatarsales. Se presentan comentarios adicionales y el mapa de distribucion de todas las especies de este género
