Overview of the Spirit Mars Exploration Rover Mission to Gusev Crater: Landing site to Backstay Rock in the Columbia Hills

2006

Spirit landed on the floor of Gusev Crater and conducted initial operations on soil covered, rock-strewn cratered plains underlain by olivine-bearing basalts. Plains surface rocks are covered by wind-blown dust and show evidence for surface enrichment of soluble species as vein and void-filling materials and coatings. The surface enrichment is the result of a minor amount of transport and deposition by aqueous processes. Layered granular deposits were discovered in the Columbia Hills, with outcrops that tend to dip conformably with the topography. The granular rocks are interpreted to be volcanic ash and/or impact ejecta deposits that have been modified by aqueous fluids during and/or after…

Vertical profiling of convective dust plumes in southern Morocco during SAMUM

2011

Lifting of dust particles by dust devils and convective plumes may significantly contribute to the global mineral dust budget. During the Saharan Mineral Dust Experiment (SAMUM) in May–June 2006 vertical profiling of dusty plumes was performed for the first time. Polarization lidar observations taken at Ouarzazate (30.9°N, 6.9°W, 1133 m height above sea level) are analyzed. Two cases with typical and vigorous formation of convective plumes and statistical results of 5 d are discussed. The majority of observed convective plumes have diameters on order of 100–400 m. Most of the plumes (typically 50–95%) show top heights <1 km or 0.3DLH with the Saharan dust layer height DLH of typically 3–…

Oppressive Faces of Whiteness in Walter Mosley’s Devil in a Blue Dress

2018

Walter Mosley’s Devil in a Blue Dress contributes significantly to the literary debate on the definition of whiteness. The socio-historical construction of whiteness emerging from the novel is amplified by white imagery dovetailing with the claims made about white people directly. For the African American first person narrator, Easy Rawlins, living in post-World War II Los Angeles, whiteness mostly spells terror. The oppressive faces of whiteness consist in the following trajectories: property relations, economic exploitation, labour relations, the legal system, different miens of oppressive white masculinity denigrating blackness, spatial dynamics of post-World War II Los Angeles and the w…

Self-similar focusing with generalized devil's lenses

2011

[EN] We introduce the generalized devil's lenses (GDLs) as a new family of diffractive kinoform lenses whose structure is based on the generalized Cantor set. The focusing properties of different members of this family are analyzed. It is shown that under plane wave illumination the GDLs give a single main focus surrounded by many subsidiary foci. It is shown that the total number of subsidiary foci is higher than the number of foci corresponding to conventional devil's lenses; however, the self-similar behavior of the axial irradiance is preserved to some extent.

Twin axial vortices generated by Fibonacci lenses.

2013

Optical vortex beams, generated by Diffractive Optical Elements (DOEs), are capable of creating optical traps and other multifunctional micromanipulators for very specific tasks in the microscopic scale. Using the Fibonacci sequence, we have discovered a new family of DOEs that inherently behave as bifocal vortex lenses, and where the ratio of the two focal distances approaches the golden mean. The disctintive optical properties of these Fibonacci vortex lenses are experimentally demonstrated. We believe that the versatility and potential scalability of these lenses may allow for new applications in micro and nanophotonics.

Patto col diavolo e conversione nel «Theophilus» e nel «Basilius» di Rosvita di Gandersheim

2019

Questo documento esplora il tema del "patto con il diavolo" in due brevi poemi agiografici, "Teofilo" e "Basilius", composti circa nel 960 dalla suora sassone Hrotsvitha di Gandersheim. In queste poesie, il tema in questione è strettamente legato alla "conversione", un argomento che Hrotsvitha affronta spesso nelle sue opere. This paper explores the theme of the “pact with the devil” in two hagiographical short poems, «Theophilus» and «Basilius», composed about 960 by the Saxon nun Hrotsvitha of Gandersheim. In these poems, the theme in question is strictly related to the “conversion”, a topic that Hrotsvitha frequently deals with in her works. Cet article interroge le thème du “pacte avec …

I nomi dei venti in Sicilia tra toponomastica, geomorfologia e “mondo magico”. Possibili itinerari di ricerca

2014

Il sistema anemonomastico siciliano appare leggibile su due livelli: da un lato i nomi dialettali dei venti ripropongono in larga misura quelli presenti nell’italiano tramontana, maestrale, greco, scirocco, libeccio, dall’altro si rileva un numero impressionante di anemonimi rifatti su un toponimo e, più spesso, sull’etnico corrispondente, se il paese che dà il nome al vento è situato lungo la direzione da cui esso spira. Ciò è particolarmente evidente per i nomi dei venti “freddi”. Per essi, mediante una ricerca su una piccola porzione del territorio siciliano le Madonie , è stato possibile raccogliere almeno due anemonimi di origine toponimica in ciascuno dei centri indagati. Mediante lo …
