The Guilty Breast: A Fleshy Semiotics

The Guilty Breast: A Fleshy Semiotics takes up the subject of the nude female breast, from St. Augustine\u27s developing and a shifting semiotic theory of signs and the flesh in Christian doctrine through feminist theories and Foucault\u27s analysis of the scientific “Gaze†to the protests of breastfeeding on social media, such as Facebook and Instagram, and in the public sphere. The dissertation argues that boobs teach us how to see by examining the breast\u27s semiotic anatomy in five parts. “Chapter One: Nipple†asserts that breasts are both…and: maternal and sexual, subjective and objective, metaphoric and actual. “Chapter Two: Cleavage†juxtaposes St. Augustine with French feminist Hélène Cixous to reveal their shared life project of making “the sign†(and substance) of the guilty body—and by extension/ostension, female breasts—morally good. “Chapter Three: Milk†“mangles†and disrupts “the Gaze†of biological theory by dripping thirst, claiming that leaking itself is onto-epistemological. “Chapter Four: Areola†highlights social media\u27s censorship of breastfeeding to explore socially constructed borders. “Chapter Five: Ducts†investigates two political examples of breasts-as-weapon. “Chapter Six: Support†offers “breast semiotics†as a new hermeneutic by which to read nude female breast texts via the plurality of bodies and concludes with a visual example

Weak-Type estimates for the metaplectic representation restricted to the shearing and Dilation subgroup of SL(2, ℝ)

We consider the subgroup G of SL(2, ℝ) consisting of shearing and dilations, and we study the decay at infinity of the matrix coefficients of the metaplectic representation restricted to G. We prove weak-type estimates for such coefficients, which are uniform for functions in the modulation space M 1 . This work represents a continuation of a project aiming at studying weak-type and Strichartz estimates for unitary representations of non-compact Lie groups

Horocyclic harmonic Bergman spaces on homogeneous trees

The main focus of this contribution is on the harmonic Bergman spaces $\mathcal{B}_{\alpha}^{p}$ on the $q$-homogeneous tree $\mathfrak{X}_q$ endowed with a family of measures $\sigma_\alpha$ that are constant on the horocycles tangent to a fixed boundary point and turn out to be doubling with respect to the corresponding horocyclic Gromov distance. A central role is played by the reproducing kernel Hilbert space $\mathcal{B}_{\alpha}^{2}$ for which we find a natural orthonormal basis and formulae for the kernel. We also consider the atomic Hardy space and the bounded mean oscillation space. Appealing to an adaptation of Calder\'on-Zygmund theory and to standard boundedness results for integral operators on $L^p_\alpha$ spaces with H\"ormander-type kernels, we determine the boundedness properties of the Bergman projection

High Temperature Transformations in a Steel-TiCN Cermet

The influence of the carbon content on the microstructure, phase transformation and hardness of an iron-based cermet is studied. The cermet is constituted by a high-alloyed steel as matrix, and TiCN particles (50 vol.%) as reinforcement. The material is produced by conventional powder metallurgy techniques, that is, uniaxial pressing and sintering, and the carbon content is varied from 0 wt.% to 1 wt.%. The aim of the research is the understanding of the transformations undergone by the material with increasing C amounts when temperature is increased. For this purpose, the cermet is studied by mechanical spectroscopy (MS) and differential thermal analysis (DTA) and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and hardness measurements. The equilibrium phase diagram calculated by ThermoCalc software contributes to explain the differences found on phase transformations with respect to the C content of the cermet.The authors would like to acknowledge the financial support from the Spanish Ministry of Science and Innovation through the R&D Project MAT2009-14448-C02 and Regional Government of Madrid through the program ESTRUMAT-CM (Ref.

Clinical, Histological and Trichoscopic Correlations in Scalp Disorders

Trichoscopy is the term coined for the dermoscopic imaging of scalp and hair. This diagnostic technique, simple and noninvasive, can be used as a handy bedside tool for the diagnosis and follow-up of hair and scalp disorders. It allows the recognition of morphologic structures not visible by the naked eye and provides the clinician with a range of dermoscopic findings necessary for differential diagnosis. Trichoscopy observation can be broadly grouped as interfollicular patterns and follicular patterns. Recently, a third mixed class, called the follicular plus interfollicular pattern, has been introduced. Some of these features are specific to a certain scalp disease, while others can be found in many hair disorders. Although studies suggest that the use of trichoscopy can improve clinical accuracy, further investigation is needed. This review provides update information on the trichoscopic features of the most common scalp disorders, striving to show a histopathological and clinical correlation

Recent changes in macroalgae distribution patterns in the Orbetello lagoon (Italy)

This study related recent distribution changes in seven macroalgae taxa (Acetabularia acetabulum, Chaetomorpha linum, Cladophora sp., Gracilariopsis longissima, Spyridia sp., Ulva laetevirens, Valonia aegagrophyla) to spatial (basin) and temporal (time) trophic differences in a meso-eutrophic Mediterranean coastal lagoon (Orbetello, Italy). In July 2003 and July 2009, the coverage percentage (CP) of each considered taxon was measured in 38 stations equally distributed in the Western and Eastern lagoon basins. All data were analysed using SURFER v8.0 software along with ANOVA, ANOSIM and multivariate analyses to produce geostatistical spatial distribution maps and to estimate statistical probabilities for "basin" and "time" factors. Data from this study were integrated with data on phanerogams reported by Giovani et al. (2010)to evaluate changes occurring at a functional group level from 2003-2009 using the Ecological Evaluation Index (EEI). Observed macroalgae changes may have been due to lagoon management activities performed during the study period. The removal of direct nitrate inputs seems to have forced specie-specific shifts that were highly significant only in the Western basin. Statistically significant differences at the taxon level have been indicated for Spyridia sp. (basin and time) and Cladophora sp. (time) taxa. Other non-significant changes included a rarefaction of Chaetomorpha linumin the Western basin and Spyridia sp. in the Eastern basin, and an increase of Gracilariopsis longissima, C. linum and Valonia aegagrophyla in the Eastern basin. EEI application indicated a general improvement in water quality due to management measures applied in Western basin, whereas the Eastern basin evidences stability/slight degradation from 2003-2009

Dermoscopy and methyl aminolevulinate: A study for detection and evaluation of field cancerization

Actinic keratosis (AK) is a keratinocyte intraepidermal neoplasia UV light – induced that frequently appears in sun-exposed areas of the skin. Although historically AK was de fi ned as “ precancerous ” , actually it is considered as the earliest stage of squamous cell carcinoma (SCC) in situ. Since AKs can progress into invasive SCC, their treatment isrecommended. AKsrarely developasa singlelesion;usually multiplelesions commonly affect anen- tire area of chronically actinic damaged skin. This has led to the concept of “ fi eld cancerization ” , an area chroni- cally sun-exposed that surrounds peripherally visible lesions, in which are individualized subclinical alterations. One of the main principles endpoint in the management of AKs is the evaluation and the treatment of fi eld cancerization. In this view, in order to detect and quantify fi eld cancerization, we employed a method based on the topical application of methyl aminolevulinate (MAL) and the detection of the fl uorescence emitted by its metabolite Protoporphyrin IX (PpIX); then, considering the extension and the intensity of measured fl uores- cence, we create a score of fi eld cancerization. The results show that patients underwent to daylight PDT had a reduction of total score, from T0 to T2. Whereas in the group untreated we observed a stability of total score or a slightly worse. So, the method and the score used allows to evaluate with a good approximation the dimension of fi eld cancerization and show the modi fi cation of it after treatment

Approaches to ontology development by non ontology experts

Untrained users in the development of ontologies are challenged by the formal representation languages that underlie the most common ontology editing tools. To reduce that barrier, many efforts have gone in the creation of Controlled Languages (CL) translatable into ontology structures. However, CLs fall short of addressing a more profound problem: the selection of the most appropriate ontology modelling component for a certain modelling problem, regardless of the underlying representation paradigm. With the aim of approaching non ontology expert's difficulties in selecting the most appropriate modelling solution, we propose a Natural Language (NL) guided approach based on a repository of Lexico-Syntactic Patterns associated to consensual modelling solutions, i.e., Ontology Design Patterns. By relying on this repository, untrained users can formulate in NL what they want to model in the ontology, and obtain the corresponding design pattern for the modelling issue

A structural and mechanistic understanding of copper(II)-bis(oxazoline) catalysed asymmetric aziridination; an EPR and ENDOR investigation

X- and Q-band EPR/ENDOR spectroscopy was used to study the structure of a series of heteroleptic and homoleptic copper(II)-bis(oxazoline) complexes, based on the (−)-2,2′-isopropylidenebis[(4S)-4-phenyl-2-oxazoline] (1) ligand and bearing different counterions (chloride versus triflate); labelled [Cu(II)(1a-c)]. The geometry of the two heteroleptic complexes, [Cu(II)(1a)] and [Cu(II)(1c)], was found to depend on the choice of counterion. Formation of the homoleptic complex was only evident when the Cu(II)(OTf)2 salt was used whereas Cu(II)Cl2 inhibited the transformation from heteroleptic to homoleptic complex. The hyperfine and quadrupole parameters for the surrounding ligand nuclei were determined by ENDOR. Well resolved 19F and 1H couplings confirmed the presence of both coordinated water and TfO- counterions in the [Cu(II)(1a)] complex. The structure of other copper(II)-bis(oxazoline) derivatives, based on 2,2’- methylenebis[(4S)-4-phenyl-2-oxazoline] (2), and 2,2’-isopropylidenebis[(4S)-4-tertbutyl- 2-oxazoline (3) were then investigated using X- and Q-band EPR/ENDOR spectroscopy. Variations in the structures of the complexes as a function of different counterions were also investigated; for ligand 2, X = TfO-, Cl- and for ligand 3, X = TfO-, Cl-, SbF6 - (where X = counterion). Formation of the homoleptic complex was evident when the Cu(II)(OTf)2 and Cu(II)Cl2 salts were used with ligand 2, but only when using the Cu(II)(OTf)2 salt with ligand 3. The substituents on the chiral carbons of the oxazoline rings and on the bridging carbon backbone were found to affect the electron spin density of the structures. An X-band EPR investigation of the interaction of substrates (pyridine, iodobenzene, (diacetoxyiodo)benzene, styrene and PhI=NTs) with [Cu(II)(1a)] was also performed, before probing the [Cu(II)(1a)] catalysed asymmetric aziridination of styrene, with PhI=NTs as the nitrene source. Using EPR to monitor the course of the reaction after the addition of styrene + PhI=NTs revealed the formation of an additional paramagnetic species, for which the g/CuA parameters indicated a change to the equatorial environment of the Cu(II) centre. This was discussed within the context of the proposed reaction mechanism which suggests the involvement of a copper-nitrene intermediate
