Factors Associated with Nurses’ Intention to Leave Their Jobs after the Fukushima Daiichi Nuclear Power Plant Accident

We conducted a survey among nurses who were working at the Fukushima Medical University Hospital at the time of the Fukushima Daiichi Nuclear Power Plant accident to clarify the factors associated with their intention to leave their jobs during the radiation emergency. We asked 345 nurses (17 men and 328 women) about their intention to leave their jobs after the accident. We also asked about relevant factors including the participants\u27 demographic factors, living situation, working status, and knowledge of radiation health effects. We found that living with preschoolers (OR=1.87, 95%CI: 1.02-3.44, p=0.042), anxiety about life in Fukushima City after the accident (OR=5.55, 95%CI: 1.18-26.13, p=0.030), consideration of evacuation from Fukushima after the accident (OR=2.42, 95%CI: 1.45-4.06, p=0.001), consideration of the possible radiation health effects in children (OR=1.90, 95%CI: 1.02-3.44, p=0.042), and anxiety about relationships with colleagues in the hospital after the accident (OR=3.23, p=0.001) were independently associated with the nurses\u27 intention to leave their jobs after the accident. On the other hand, the percentage of nurses with knowledge on radiation health effects was relatively low among those who had the intention to leave the job and among those who did not have the intention to leave the job after the accident, with no significant differences between the two groups. Our results suggest the need for an education program for nurses regarding radiation health effects

The look of the con: Eleven thoughts on the historical absence of subtitles in film analysis

This article considers the lack of dialogue between Audio-Visual Translation and Film & Media Studies, despite the fact that both disciplines clearly have shared interests in the content of audio-visual texts. The apparent lack of any developed and consistent overlap between these areas of study is the starting point for a series of eleven ‘thoughts' that identify commonalities and differences in how film and television texts might be studied and analysed. Inspired and led by the specific example of a scene from Ocean’s Eleven (2001), the article explores the potential for interdisciplinary research collaborations through ideas of authorship, genre, history, technology, industry labour, and reception and audience studies. While identifying areas where different theories might clash or complicate collaboration, the article also highlights potent areas where shared experience and different perspectives could enrich both fields

Elaboration of a new compositional kinetic schema for oil cracking

International audienceThe aim of this work is to get new insights into oil cracking mechanisms. The investigation was focused on the thermal stability of the heavy chemical classes such as the C14+ saturates, C14+ aromatics, and the polar fraction (resins + asphaltenes). Artificial maturation was performed in closed pyrolysis system in the temperature range 300375 C for following a large range of conversion for the three initial chemical classes. Pyrolysis products are described as H2S, C1, C2, C3C4 gases, C6C14 saturates, C6C14 aromatics, C14+ saturates, C14+ aromatics, NSOs and prechar. In a first step, the total C14+ aromatics of the initial oil was isolated and artificially matured. They generated a significant part of saturated compounds and new heavy aromatics which were assumed to be methylated structures. The proportion of initial and produced aromatics was determined based on the decrease of the hydrogen content. Then, a kinetic model was elaborated for their specific bulk and compositional kinetic parameters which was taken as an initial guess when optimising the global kinetic model for the total C14+ oil. A tentative global kinetic model for the total C14+ oil was elaborated which well simulated laboratory experiments for both global conversions and yields of generated products. When this model is used for extrapolating laboratory results to natural reservoirs assuming a geothermal heating rate of 2 C/Ma, predicted oil thermal behavior is not in contradiction with observed field data. Indeed, aromaticity is decreasing above 140 C whereas, the yield of C14+ saturates starts to decrease above 170180 C. However this comparison is only qualitative since this model was not integrated into a real case study in which the full process of generationexpulsion and oil cracking must be totally described. The reverse relative thermal stability of the C14+ saturates and aromatics between laboratory and geological conditions is explained by the large difference of A and E of the two chemical classes. Finally, this model was elaborated on a Type II oil only and needs to be tested also on other oils of different chemical composition, either paraffinic or enriched in NSOs

Separation and Characterisation of the C

The purpose of this work is to isolate and characterise the light fraction of Safaniya, a conventional nonbiodegraded type II crude oil. This fraction is devoted to perform a kinetic study on the thermal stability of the light aromatic fraction of crude oil. The light cut <250°C, corresponding to the C15- components, was obtained by fractionated distillation. This cut contains saturated and aromatic hydrocarbons. Kinetic studies on the thermal stability of aromatics require to separate the aromatic fraction without any trace of saturated compounds and derive detailed information on its composition. We have therefore developed a method permitting to achieve a clear-cut separation of these two families. Liquid phase chromatography on activated silica gel column was thus optimised for separating a complete and pure aromatic fraction, in large enough amounts for characterisation and all subsequent kinetic studies. Thereafter, Preparative High Performance Liquid Chromatography (PHPLC) of an aliquot was used to separate the aromatic compounds according to aromatic ring number into monoaromatics, indenes, diaromatics and biphenyls. Detailed molecular characterisation of the aromatic sub-fractions thus obtained was achieved by Gas Chromatography coupled to Mass Spectrometry (GC/MS). Then, individual aromatic compounds were quantified by GC-FID. These compounds are benzene, C1-C7 benzenes, naphthalene, C1-C7 naphthalenes, indane, C1-C4 indanes, indene, C1-C7 indenes, C1-C3 tetralins and and sulphur-containing aromatics (methyl- and ethylbenzothiophenes). The detailed knowledge thus derived on the composition of different class and its relative abundance in the total C15- aromatics will allow following its temporal evolution during subsequent pyrolysis experiments

Expertises croisées dans la dégénérescence maculaire liée à l'âge. Focus sur la physiopathologie, l'angiogenèse, les données pharmacologiques et cliniques [Review and expert opinion in age related macular degeneration. Focus on the pathophysiology, angiogenesis and pharmacological and clinical data].

Age related macular degeneration (AMD) is a pathological aging of the macula, brought about by the interaction of genetic and environmental factors. It induces geographic atrophy of the retina and/or choroidal neovascularization. In the latter, abnormal vessels develop from the choriocapillaris, with the involvement of VEGF (vascular endothelial growth factor). The VEGF family includes several factors, including VEGF-A, B, C, D, F and PlGF (placental growth factor). Their biological properties and their affinities to the VEGFR1, VEGFR2 and VEGFR3 receptors found on endothelial cells differ. Exudative AMD involves mainly VEGF-A and VEGF-R2. Anti-VEGF agents used in ophthalmology (ranibizumab, bevacizumab and aflibercept) are designed to primarily target this pathway. In vitro, all have sufficient affinity to their ligands. Their therapeutic efficacy must therefore be judged based on clinical criteria. In clinical practice, the minimum number of injections required for a satisfactory result appears to be comparable with all the three. The few available studies on therapeutic substitutions of anti-VEGF compounds suggest that some patients may benefit from substituting the anti-VEGF in cases of an unsatisfactory response to an initial molecule. Although local side effects, including increased risk of geographic atrophy, and systemic effects, including vascular accidents, have been suggested, these risks remain low, specially compared to the benefits of the treatment. Differences in safety between anti-VEGF are theoretically possible but unproven

Mechanical properties of rat cardiac skinned fibers are altered by chronic growth hormone hypersecretion.

Chronic growth hormone (GH) hypersecretion in rats leads to increased isometric force without affecting the unloaded shortening velocity of isolated cardiac papillary muscles, despite a marked isomyosin shift toward V3. To determine if alterations occurred at the level of the contractile proteins in rats bearing a GH-secreting tumor (GH rats), we examined the mechanical properties of skinned fibers to eliminate the early steps of the excitation-contraction coupling mechanism. We found that maximal active tension and stiffness at saturating calcium concentrations (pCa 4.5) were markedly higher in GH rats than in control rats (tension, 52.9 +/- 5.2 versus 38.1 +/- 4.6 mN.mm-2, p &lt; 0.05; stiffness, 1,105 +/- 120 versus 685 +/- 88 mN.mm-2.microns-1, p &lt; 0.01), whereas values at low calcium concentrations (pCa 9) were unchanged. In addition, the calcium sensitivity of the contractile proteins was slightly but significantly higher in GH rats than in control rats (delta pCa 0.04, p &lt; 0.001). The crossbridge cycling rate, reflected by the response to quick length changes, was lower in GH rats than in control rats (62.0 +/- 2.6 versus 77.4 +/- 6.6 sec-1, p &lt; 0.05), in good agreement with a decrease in the proportion of alpha-myosin heavy chains in the corresponding papillary muscles (45.5 +/- 2.0% versus 94.6 +/- 2.4%, p &lt; 0.001). The changes in myosin heavy chain protein phenotype were paralleled by similar changes of the corresponding mRNAs, indicating that the latter occurred mainly at a pretranslational level. These results demonstrate that during chronic GH hypersecretion in rats, alterations at the myofibrillar level contribute to the increase in myocardial contractility observed in intact muscle
