Proximal aortic stiffening in Turner patients may be present before dilation can be detected : a segmental functional MRI study

Background: To study segmental structural and functional aortic properties in Turner syndrome (TS) patients. Aortic abnormalities contribute to increased morbidity and mortality of women with Turner syndrome. Cardiovascular magnetic resonance (CMR) allows segmental study of aortic elastic properties. Method: We performed Pulse Wave Velocity (PWV) and distensibility measurements using CMR of the thoracic and abdominal aorta in 55 TS-patients, aged 13-59y, and in a control population (n = 38; 12-58y). We investigated the contribution of TS on aortic stiffness in our entire cohort, in bicuspid (BAV) versus tricuspid (TAV) aortic valve-morphology subgroups, and in the younger and older subgroups. Results: Differences in aortic properties were only seen at the most proximal aortic level. BAV Turner patients had significantly higher PWV, compared to TAV Turner (p = 0.014), who in turn had significantly higher PWV compared to controls (p = 0.010). BAV Turner patients had significantly larger ascending aortic (AA) luminal area and lower AA distensibility compared to both controls (all p < 0.01) and TAV Turner patients. TAV Turner had similar AA luminal areas and AA distensibility compared to Controls. Functional changes are present in younger and older Turner subjects, whereas ascending aortic dilation is prominent in older Turner patients. Clinically relevant dilatation (TAV and BAV) was associated with reduced distensibility. Conclusion: Aortic stiffening and dilation in TS affects the proximal aorta, and is more pronounced, although not exclusively, in BAV TS patients. Functional abnormalities are present at an early age, suggesting an aortic wall disease inherent to the TS. Whether this increased stiffness at young age can predict later dilatation needs to be studied longitudinally

Reminiscences of East Greenwich

Address delivered before the East Greenwich Business Men’s Association by Henry E. Turner, April 11, 1892. Henry E. Turner, a member of the East Greenwich Business Men’s Association, recounts the early history of notable events and people of the town of East Greenwich, Rhode Island, during the first half of the 19thcentury.https://digitalcommons.providence.edu/ri_history/1005/thumbnail.jp

Advective collisions

Small particles advected in a fluid can collide (and therefore aggregate) due to the stretching or shearing of fluid elements. This effect is usually discussed in terms of a theory due to Saffman and Turner [J. Fluid Mech., 1, 16-30, (1956)]. We show that in complex or random flows the Saffman-Turner theory for the collision rate describes only an initial transient (which we evaluate exactly). We obtain precise expressions for the steady-state collision rate for flows with small Kubo number, including the influence of fractal clustering on the collision rate for compressible flows. For incompressible turbulent flows, where the Kubo number is of order unity, the Saffman-Turner theory is an upper bound.Comment: 4 pages, 1 figur

Review Article: Victor Turner, Liminality and Cultural Performance.

Victor Witter Turner (1920 – 1983), working with his wife Edith Turner, was an anthropologist deeply concerned with ritual both in tribal communities and in the contemporary developed world. His early fieldwork in African villages in the 1950s was typical of the career development of field anthropologists at that time. He developed a special interest in rituals, seeing these as social drama in addition to the religious expression of the sacred. He drew on the work of Arnold van Gennep (1960, originally 1908) on rites of passage (viz. birth, marriage, death and sometimes puberty initiation), translated into English in 1960: Turner focused on the concept of limen, ‘threshold’ and the term liminality. He later applied this to all performance, including the theatr

Analysis of Surface Collections from Areas A and B at the Sam Roberts Site (41CP8) on Prairie Creek, Camp County, Texas

The Sam Roberts site is a large ancestral Caddo mound center and habitation site on the floodplain of Prairie Creek, an eastward-flowing tributary to Big Cypress Creek, as well as on an upland landform south of the creek. Robert L. Turner, Jr.\u27s surface collections came from what he labeled Area A (in a plowed field in the floodplain) and Area B (in the uplands), several hundred meters apart. His notes with the collection also indicated that Caddo vessels had been plowed up in another cultivated field well to the east of Area A in the Prairie Creek floodplain. The two Turner surface collection areas appear to correspond to two of the five distinct subareas (AE) identified by Thurmond. Thurmond\u27s Area A is the same as Turner\u27s, and Thurmond describes it as a dense concentration or occupation debris on a floodplain rise adjacent to Prairie Creek, associated with a dark brown greasy soil. Large, dark outlines associated with concentrations of wattle-impressed daub may mark the locations of structures. Area A has a Late Caddo Titus phase component. Thurmond\u27s Area B is the same as Turner\u27s Area B, and this area is marked by an apparent Early or Middle Caddo settlement. Although unnoted by Turner, there was a Late Caddo, Titus phase mound and a midden deposit about 200 m west of Area A, also in the floodplain of Prairie Creek (Thurmond\u27s Area E). The mound (15.2 m in diameter and 1.1 min height) was built over a burned circular structure. Two radiocarbon dates on burned structural materials have median calibrated ages of A.D. 1567 and A.D. 1681; these dates, along with the brushed and brushed-punctated sherds recovered in the excavations, indicate that the Area E mound was built during Titus phase times, along with a number of other mounds in the Big Cypress Creek basin. Thurmond\u27s Area D may be at the same location where Turner noted vessels had been plowed up; this area also has Titus phase occupational remains. Thurmond\u27s Area Cis just east of Area B, and also represents an Early to Middle Caddo habitation area with substantial amounts of ceramic sherds. Finally, the recovery of Gary dart points from Area A indicates that there was a limited Woodland period use in this part of the Sam Roberts site

Cartesian Dualism and the Intermediate State: A Reply to Turner Jr

In this paper, I propose to analyse two objections raised by Turner Jr in his paper “On Two Reasons Christian Theologians Should Reject The Intermediate State” in order to show that the intermediate state is an incoherent theory. As we shall see, the two untoward consequences that he mentions do not imply a metaphysical or logical contradiction. Consequently, I shall defend an Intermediate State and I shall propose briefly one metaphysical conception of the human being able to reply to Turner Jr’s objections
