Abstract:

Optimized Planning and Scheduling of Pressure Equipment Inspections at Comah Establishments.In a process establishment, where the legislation on the control of major accidents hazard (COMAH) is enforced, the operator's duties include the implementation of a Safety Management System, which addresses all the procedures significant for safety. A critical issue of the SMS is the planning and the scheduling of mechanical integrity inspections on pressure equipment. This is due to high number of components — including pipes, unfired and fired vessels, pumps and valves, — which could require different technical and organization procedures for testing or inspection. Usually, mechanical integrity inspections may request higher resource use than other safety related activities. The paper presents a model for inspection planning and scheduling, in order to integrate safety issues with other technical and economical issues.

Abstract:

“De-energise to trip” is a long established principle because of the danger of common cause failures. Although there is little published on this topic, it is covered in the section “Protection systems (trips and interlocks)” in the HSE Technical Measure Document for COMAH sites, but the quality of UPS, diagnostics etc. is now very different from the last century. As well as the obvious effects of architecture, failure modes and frequency on the number of spurious trips and failures to dangers, we have also studied the relationships between design policies, (for example, overrides and diagnostic coverage), testing policies, repair policies, operating policies and their effects on common cause failures. The effects of different policies on spurious trips and failures to danger would be illustrated with practical examples from the energy industry: oil and gas production and power stations.

Abstract:

Abstract Coma is one of the most common ocular higher order aberrations and highly affects the quality of image. It is assumed that corneal aberrations are balanced by internal (lenticular) aberrations so that retinal image quality may not have great impact. However, during accommodation, the shape, position, and curvature of the crystalline lens changes which might disrupt this balance between internal and corneal aberration. This study aimed to investigate the effect of accommodation on primary coma ( C 3 − 1 and C 3 1 ) and secondary coma ( C 5 − 1 and C 5 1 ) in relaxed and accommodated eyes. Zernike coefficients were measured in 53 subjects with Hartmann-Shack aberrometer both at the central and peripheral retina up to 30° off-axis in horizontal and vertical meridians. The process was repeated with 2.50 D accommodation stimulus and comas were compared with and without accommodation. Root-mean-square of total coma was also assessed. With accommodation, vertical comas changed to more negative value and horizontal comas changed to more positive values in most of the off-axis positions. In contrast, the secondary vertical comas became less negative and secondary horizontal comas became more negative with accommodation in most of the off-axis fixations. Thus, the results showed that accommodation affects coma which depends up on position of the fixation.

Abstract:

We present the first observations of outbursting comet C/2015 ER61 (PANSTARRS) with the Multi-Unit Spectroscopic Explorer (MUSE). The comet was observed on April 9, 2017, only five days after it underwent a significant outburst during which the total brightness increased by a factor of ~7.5. Based on the MUSE observations, we produce simultaneous maps of the CN, C2, NH2 comae, and the dust coma. In turn, we applied image enhancement techniques in order to reveal features in the coma. By comparing the coma morphology for the dust and CN, C2, and NH2, we investigate the release mechanism of those gas species in the coma of comet ER61. We present evidence that NH2 could be released by icy or organic-rich dust grains.

Abstract:

ABSTRACT Remote and in situ observations of cometary gases have revealed the presence of a wealth of complex organic molecules, including carbon chains, alcohols, imines, and the amino acid glycine. Such chemical complexity in cometary material implies that impacts by comets could have supplied reagents for prebiotic chemistry to young planetary surfaces. However, the assumption that some of the molecules observed in cometary comae at millimetre wavelengths originate from ices stored inside the nucleus has not yet been proven. In fact, the comae of moderately-active comets reach sufficient densities within a few thousand kilometres of the nucleus for an active (solar radiation-driven) photochemistry to ensue. Here, we present results from our latest chemical-hydrodynamic models incorporating an updated reaction network, and show that the commonly-observed HC3N (cyanoacetylene) and NH2CHO (formamide) molecules can be efficiently produced in cometary comae as a result of two-body, neutral–neutral, gas-phase reactions involving well-known coma species. In the presence of a near-nucleus distributed source of CN (similar to that observed by the Rosetta spacecraft at comet 67P), we find that sufficient HC3N and NH2CHO can be synthesized to match the abundances of these molecules observed previously in Oort cloud comets. The precise coma origins of these (and other) complex organic molecules can be verified through radio interferometric mapping observations, for example using the Atacama Large Millimeter/submillimeter Array.

Abstract:

Abstract There was an unprecedented opportunity to study the inner dust coma environments, where the dust and gas are not entirely decoupled, of comets 45P/Honda–Mrkos–Pajdus̆áková (45P/HMP) from 2016 December 26 to 2017 March 15, and 46P/Wirtanen from 2018 November 10 to 2019 February 13, both in visible wavelengths. The radial profile slopes of these comets were measured in the R and HB-BC filters most representative of dust, and deviations from a radially expanding coma were identified as significant. The azimuthally averaged radial profile slope of comet 45P/HMP gradually changes from −1.81 ± 0.20 at 5.24 days preperihelion to −0.35 ± 0.16 at 74.41 days postperihelion. Contrastingly, the radial profile slope of 46P/Wirtanen stays fairly constant over the observed time period at −1.05 ± 0.05. Additionally, we find that the radial profile of 46P/Wirtanen is azimuthally dependent on the sky-plane-projected solar position angle, while that of 45P/HMP is not. These results suggest that comets 45P/HMP and 46P/Wirtanen have vastly different coma dust environments and that their dust expansion properties are distinct. As evident from these two comets, well-resolved inner comae are vital for detailed characterization of dust environments.

Abstract:

The rate of accumulation of malonic dialdehyde was increased, the activities of superoxide dismutase, NADP-dependent glucose- 6-phosphate, malate, isocitrate dehydrogenases and glutathione reductase decreased, and the levels of diene conjugates decreased in the hemispheres and brain stem of rats subjected to 7-9 hypoglycemic comas. The activities of neutral and acid proteases were increased in the stem structures. The detected changes indicate an oxidative stress developing in the nerve tissue after repeated hypoglycemic exposures. Such changes appear after glucose arrest of hypoglycemic coma and can be important in the pathogenesis of posthypoglycemic encephalopathy.

Abstract:

AbstractThere are a number of studies describing the gross range of morpho-anatomical variability in epiphyticTillandsiaspecies, but the interspecific variation in seed traits remain largely unexplored, although these play an important role in determining dispersal and establishment success. In order to evaluate interspecific variation in seed morphology, anatomy and germination, we sampled sixTillandsiaspecies from the Yucatan peninsula, Mexico, distributed along a precipitation gradient. We studied morpho-anatomical traits (seed length, seed mass, ratio of coma to seed, ratio of embryo to endosperm), seed terminal velocity in still air, and performed histochemical analyses and germination trials under controlled conditions.Tillandsia recurvatadiffers from the other five species in the structure of the plumose coma; it was the only species lacking an endosperm and showed distinct seedling development. Among the species, bigger seeds were related to longer comas, and had higher germinability. Overall, seed terminal velocity was invariably slow, compared with reports of other anemochorous species, suggesting a high dispersal potential. Taxonomical and ecological implications of our results are discussed.

Abstract:

Our knowledge of the volatile composition of comets has advanced considerably since the last IAU Astrochemistry Symposium, in large part due to the apparition of comet Hale-Bopp and its study with both new ground-based instruments and from spacecraft. Some 23 or 24 coma molecules are now known which are probably, at least in part, volatile constituents of the nucleus. Relative abundances have been measured for rarer isotopomers of molecules containing 13C, 15N, 34S, and D, and significant isotopic fractionation is observed for D-containing species. There are striking similarities in both relative abundances of molecular constituents and in isotopic fractionation between material in dense interstellar clouds and that in cometary comae. Whether this indicates that cometary nuclei consist of relatively unprocessed interstellar matter is less clear, since the observed coma composition is not simply related to the nuclear composition, and since recent chemical models of the outer solar nebula mimic interstellar chemistry in important respects.

Abstract:

AbstractWe investigated comets active at large heliocentric distances using observations obtained at the 6-m BTA telescope (SAO RAS, Russia). Long-slit and photometric modes of the focal reducer SCORPIO were used. Two of the comets, 29P/Schwassmann-Wachmann 1 (SW1) and C/2002 VQ94 (LINEAR) were observed to be emission rich. Detection of CO+ and N2 + emissions in the comae of these comets is evidence that they were formed in the outer regions of the Solar System or in a pre-solar interstellar cloud in a low temperature environment with T ~ 25K. The ratio of N2+/CO+ is equal to 0.011 and 0.027 for SW1 and LINEAR, respectively. Comet LINEAR is the most distant object in the Solar System (7.332 AU) for which CO+ and N2+ are measured. The photometric maximum of the isolated CO+ coma in comet LINEAR is shifted by 1.4 arcsec (7.44 × 103 km) relative to the photometric maximum of the dust coma. This shift deviates from the sunward direction by 63 degrees.

Abstract:

The phrase ὑγρòν ὓδωρ in Anacreontic 33.22 requires more explanation than has until now been offered: the parallel passages cited by M. L. West in his edition (Carmina Anacreontea, Leipzig, 1984), namely Ovid, Ars Am. 3.224, ‘nuda Venus madidas exprimit imbre comas’ and Her. 18.104, ‘madidam…imbre comam’, present the same image, but with quite a different vocabulary, whilst Patricia A. Rosenmeyer (The Poetics of Imitation: Anacreon and the Anacreontic Tradition, Cambridge, 1992, p. 80) regards it only as an example of tautology characteristic of the Anacreontic corpus. But it is by no means unique, and, both for this reason and in the context of the nature of the whole poem, it is capable of further elucidation.

Abstract:

(1) Background: The prevalence of diabetes in elderly people is frequently high. When occurring in the elderly, diabetes is often accompanied by complications and comorbidities, at least one in 60% and four or more in 40% of older people with diabetes. As far as short-term complications among the elderly are concerned, hypoglycemia and hyperglycemic crises prove to be frequent. The aim of this study was to investigate the difference in hospitalization for short-term diabetes complications in patients below and over 85 years of age. (2) Methods: Data were collected from hospital discharge records (HDRs) of all hospital admissions that occurred in Abruzzo Region, Italy, from 2006 to 2015. Only diabetic patients aged over 65 years were included. Outcomes included were diabetic ketoacidosis, hyperosmolar coma, hypoglycemic shock, iatrogenic hypoglycemic coma, and other diabetic comas. (3) Results: During the study period, 144,376 admissions were collected, 116,305 (80.56%) of which referred to patients below 85 years. Those aged over 85 years were significantly associated to all short-term diabetes-related complications with the exception of ketoacidosis. (4) Conclusions: In older diabetic patients, the avoidance of short-term diabetes complications are a greater concern than in younger patients. Diabetes management among very elderly patients should be tailored accordingly to patient characteristics.

Abstract:

Context. From August 2014 to September 2016, Rosetta escorted comet 67P/Churyumov-Gerasimenko (67P) during its journey around the Sun. One of the aims of Rosetta was to characterize cometary activity and the consequent formation of dust flux structures in cometary comae. Aims. We characterize and quantify the submicrometer- to micrometer-sized dust flux that may be shaped in privileged directions within the coma of 67P inbound to and outbound from perihelion. Methods. The in situ dust-measuring instrument GIADA, part of the Rosetta/ESA payload, consisted of three subsystems, one of which was the Micro Balance Subsystem (MBS), composed of five quartz crystal microbalances. From May 2014 to September 2016, MBS measured the submicrometer- to micrometer-sized deposited dust mass every 5 min. Results. We characterized the submicrometer- to micrometer-sized dust mass flux in the coma of 67P. The anti-sunward and the radial direction are preferred, and the flux is higher in the anti-sunward direction. The measured cumulative dust mass in the anti-sunward direction is 2.38 ± 0.04 × 10−7 kg, and in the radial direction, it is 1.18 ± 0.02 × 10−7 kg. We explain the anti-sunward dust flux as the effect of nonuniform gas emission between the night- and dayside of the nucleus, which acts in combination with the solar radiation pressure. We compared the cumulated dust mass of particles ≤5 μm with particles ≥100 μm. The retrieved ratio of ≈2% implies a differential size distribution index of ≈−3.0, which confirms that particles of size ≥0.1 mm dominate the dust coma cross-section of 67P during the entire orbit. Conclusions. Submicrometer- to micrometer-sized dust mass flux measurements were made for the first time from the arising of cometary activity until its extinction. They indicate that these particles do not provide a substantial optical scattering in the coma of 67P with respect to the scattering caused by millimeter-sized particles. In addition, MBS data reveal that the measured dust flux is highly anisotropic: anti-sunward plus radial.

Abstract:

Speech therapy can be part of the care pathway for patients recovering from comas and presenting a disorder of consciousness (DOC). Although there are no official recommendations for speech therapy follow-up, neuroscientific studies suggest that relevant stimuli may have beneficial effects on the behavioral assessment of patients with a DOC. In two case studies, we longitudinally measured (from 4 to 6 weeks) the behavior (observed in a speech therapy session or using items from the Coma Recovery Scale—Revised) of two patients in a minimally conscious state (MCS) when presenting music and/or autobiographical materials. The results highlight the importance of using relevant material during a speech therapy session and suggest that a musical context with a fast tempo could improve behavior evaluation compared to noise. This work supports the importance of adapted speech therapy for MCS patients and encourages larger studies to confirm these initial observations.

Abstract:

AbstractThree topics are briefly reviewed to examine evidence for the nature of dust grains and grain alteration by physical processes related to mainly sublimation. Namely, (1) a change of dust flux detected by in situ dust measurements beyond ~ 2 AU from the Sun suggests a disappearance of volatile ices due to sublimation below this distance, (2) an elongation angle dependence of Doppler shifts observed in the zodiacal light can be explained by the introduction of a dependence of the orbital velocity on the radiation pressure forces acting on the grains, taking into account a variation of dust structure with heliocentric distance, and (3) the variation of color temperature observed in cometary coma suggests a loss of carbon content from cometary dust grains due to sublimation. This piece of evidence agrees with the generation of carbon-bearing molecules from extended sources, as infered from observations in cometary comae.

Abstract:

ABSTRACTComets may be our best probes of the physical and chemical conditions in the outer regions of the solar nebula during that crucial period when the planets formed. The volatile composition of cometary nuclei, in particular, can be used to decide whether comets are the product of a condensation sequence similar to that invoked to explain the compositions of the planets and asteroids, or if comets are simply agglomerations of interstellar grains which have been insignificantly modified by the events that shaped the other bodies in the solar system. Although cometary nuclei are not generally accessible to observation, observations of cometary comae can illuminate at least some of the mysteries of the nuclei provided one has a detailed knowledge of the excitation conditions in the coma and also has access to basic atomic and molecular data on the many species present in comets. This paper examines the status of our knowledge of the volatile composition of cometary nuclei and discusses how these data are obtained.

Abstract:

ObjectiveTo review our experience with patients with spontaneous intracranial hypotension (SIH) and coma because, although disorders of consciousness may complicate SIH, no comprehensive study of such patients has been reported.MethodsUsing a prospectively maintained registry, we identified all patients with SIH in whom coma developed. Patients or their caregivers/families were contacted for follow-up. Patients were compared to a cohort of patients with SIH without coma.ResultsThe mean age of the 12 men and 3 women with SIH was 56.2 years (range 34–72 years) at the time of onset of coma. In one-third of patients, coma developed after craniotomy for subdural hematomas or for an unrelated intracranial pathology. Imaging showed brain sagging, including bilateral temporal lobe herniation, in all 15 patients and brainstem edema in 8 patients (53%). Overall, coma was reversible in 7 of 15 patients treated with epidural blood patches, in 2 of 4 treated with percutaneous glue injections, and in 6 of 6 treated surgically. Only 1 patient had residual neurologic deficit related to coma (Glasgow Outcome Scale score 4 [moderate disability]). Compared to patients with SIH without coma (n = 568), those with coma were older, more often were male, and more often underwent surgery.ConclusionsComa in SIH is rare, reversible, and invariably associated with brain sagging. Coma due to SIH may be refractory to the usual percutaneous procedures, and surgical closure of the CSF leak may be required to regain consciousness.

Abstract:

Context. Gas-phase sodium, silicon, potassium, and calcium were previously identified in mass spectra recorded in the coma of comet 67P/Churyumov-Gerasimenko, the target of the European Space Agency’s Rosetta mission. The major release process for these atoms was identified as sputtering by the solar wind. More recently, remote observations of numerous comets over a range in heliocentric distances revealed the presence of metal atoms of iron and nickel that had been released either from the nucleus or from a distributed source with a short scale length. Sputtering, however, has been dismissed as a major release process due to the attenuation of the solar wind in the comae of some of the observed targets. Aims. We investigated the presence of refractory species in the gas phase of the coma of 67P/Churyumov-Gerasimenko. This investigation includes a period close to perihelion when the solar wind was likely absent from the near-nucleus region due to the increased cometary activity. Additionally, we extended our search to iron and nickel. Methods. We analyzed in situ data from the Rosetta/ROSINA Double Focusing Mass Spectrometer DFMS. Results. We found that gas-phase silicon was present throughout the Rosetta mission. Furthermore, the presence of sodium and iron atoms near the comet’s perihelion confirms that sputtering cannot be the sole release process for refractory elements into the gas phase. Nickel was found to be below the detection limit. The search for parent species of any of the identified gas phase refractories has not been successful. Upper limits for a suite of possible fragment species (SiH, SiC, NaH, etc.) of larger parent and daughter species have been obtained. Furthermore, Si did not exhibit the same drop in signal as do common cometary gases when the spacecraft is pointed away from the nucleus. The combined results suggest that a direct release of elemental species from small grains on the surface of the nucleus or from small grains in the surrounding coma is a more likely explanation than the previous assumption of release via the dissociation of gaseous parent molecules.

Abstract:

In the Coman case, the European Court of Justice was asked whether the term "spouse" - for the purpose of EU law - includes the same-sex spouse of an EU citizen who has moved between EU Member States. The ECJ answered this question affirmatively, holding that a refusal to recognise a same-sex marriage and the resultant refusal to grant family reunification rights to a Union citizen who moves to another Member State, would constitute an unjustified restriction on the right to free movement that Union citiyens enjoy under EU law. This case comment analyses the judgment, arguing that the Court's pronouncement is a very welcome first step towards marriage equality at a cross-border level in the EU. At the same time, the case poses a number of important questions, which will only be answered in case law and practice in the years to come.
