One of the most puzzling passages of Vergil's Aeneid is the last lines of book VI where Aeneas and the Sibyl leave the underworld through the gate of ivory, the gate of false dreams. "Few passages of the Aeneid have given rise to more controversies and divergence of judgement" (Brooks Otis). In this article we analyse the linguistic context and propose a new solution to the problem.
PURPOSE: To determine if the curve length, curve form, and location of the lower-end vertebra can identify the type of scoliosis. METHODS: Standing posteroanterior and lateral radiographs of 78 women and 27 men with scoliosis aged 8 to 32 years were retrospectively analysed. Parameters measured were (1) the curve length (the number of vertebrae in the main curve), (2) the curve form (C-form, inver
Expressions are derived for photoemission, which allow experimental electron energy loss data to be used for estimating losses in photoemission. The derivation builds on new results for dielectric response and mean free paths of strongly correlated systems of two-dimensional layers. Numerical evaluations are made for Bi2Sr2CaCu2O8 (Bi2212) by using a parametrized loss function. The mean free path
Recent findings have implicated the gut microbiota as a contributor of metabolic diseases through the modulation of host metabolism and inflammation. Atherosclerosis is associated with lipid accumulation and inflammation in the arterial wall, and bacteria have been suggested as a causative agent of this disease. Here we use shotgun sequencing of the gut metagenome to demonstrate that the genus Col
BACKGROUND: Different generic quality of life instruments such as the Nottingham Health Profile (NHP) and the Short Form 36 Health Survey (SF-36) have revealed conflicting results in patients with chronic lower limb ischaemia in psychometric attributes in short-term evaluations. The aim of this study was to compare the NHP and the SF-36 regarding internal consistency reliability, validity, respons
Ruxolitinib, a novel inhibitor of Janus kinases 1 and 2, was recently approved for the treatment of myelofibrosis but, recently, attention has been drawn to potential side effects and especially opportunistic infections and virus reactivations. EBV reactivation has not previously been reported to occur in association with Ruxolitinib.
A newly developed aluminium-polymer-laminated steel reflector for use in solar concentrators was evaluated with respect to its optical properties, durability, and reflector performance in solar thermal and photovoltaic systems. The optical properties of the reflector material were investigated using spectrophotometer and scatterometry. The durability of the reflector was tested in a climatic test
The single-aliquot regenerative-dose (SAR) protocols used in retrospective dosimetry for optically stimulated luminescence measurements have been mainly developed for archaeological and geological dating of quartz and feldspar. The aim in this study is to find a read-out protocol that can generate the most reproducible signal for household salt (NaCl) at absorbed doses below 100 mGy. The relation
This paper questions assumptions about the importance of group processes for the learning outcome in PBL groups. It is argued that previous research has downplayed the occurrence and importance of such processes. Through an empirical study with collective Group Diaries in 12 PBL group of approx. 70 students over one term., the occurrence of 67 hindering incidents is demonstrated. The most frequent
A differential two-wire communication link with a 3-level asynchronous protocol is introduced. The proposed 3-level code contains information of both data and clock. Since only one edge is needed for each bit, the bandwidth of a link is efficiently utilized. The power consumption is reduced by the low-swing differential two-wire link and is further reduced by a 3-level code. The speed of the proto
OBJECTIVE: To explore the characteristics and outcome of patients after stroke admitted to early supported discharge (ESD) services, and to investigate changes over time. STUDY POPULATIONS: Patients admitted between June 1997 and September 1998 and participating in a follow-up study (n = 87) and all patients admitted in 2005-06 (n = 226). Background populations: All stroke cases in Malmö alive 3 m
The properties of the arterial vasculature depend to a large extent on the activities of smooth muscle cells, which, in turn, are determined by their extracellular environment. During pathological conditions, such as atherosclerosis, this interaction is altered. In close proximity to medial smooth muscle cells are basement membrane components, such as different isoforms of laminin. These proteins
Partial wh-movement does not exist in the modern Scandinavian languages. It is however found in Old West Scandinavian texts, but not in Old East Scandinavian texts. In this article it is argued that there is a correspondence between attested partial wh-movement and the possibility of deleting the complementizer corresponding to English that. Although complementizer deletion is possible in all mode
