Published: January 2018

Introduction: Outpatient anesthesia for the minor day care surgical procedures requires a safe anesthesia and anesthetic agents. For this purpose two study solutions propofol with ketamine (ketofol) and propofol were compared. The comparison of the both agents were assessed, evaluated and discussed in this study. Methodology: This is prospective study of 100 adult patients of both sex aged between 18-60 years with ASA physical status class I and II who were operated in the Birat Medical College teaching hospital. This study was started after approval from the ethical committee of the hospital and after written and informed consent from all participants. All patients were randomly divided into two groups. Group A (n=50) received ketamine with propofol and Group B (n=50) propofol after intravenous sedation with 2 mg of midazolam and 1 mg of butorphanol. The main aim of this study was comparison of onset of sedation, respiratory and cardiac adverse events, level of sedation using Ramsey sedation scale, requirement of sedatives, recovery time, average cost of the sedatives and postoperative complications between the two groups. All collected data are analyzed using MS Excel office 2007 and for the data analysis IBM SPSS software was used.Results: In the both groups patients were comfortable with the either anesthetic agents. Onset of anesthesia was faster in Group A. Intraoperative sedation was measured using Ramsay sedation scale and was comparable. Recovery from sedation was assessed with AVPU scale and patient was shifted to postoperative room after the verbal response. Postoperative complications seen were nausea vomiting, severe pain, ketamine induced psychotomimetic effects and all of these were treated well and discharged on the same day from the hospital.Conclusion: The combination of ketamine and propofol for the sedation in minor surgical procedures has more advantages than the propofol alone. The combination is cost effective, has better sedation and hemodynamic stability, quick recovery and fewer side effects in the post operative room.

OBJECTIVEThe second-generation Pipeline embolization device (PED), Flex, has several design upgrades, including improved opening and the ability to be resheathed, in comparison with the original device (PED classic). The authors hypothesized that Flex is associated with a lower rate of major complications.METHODSA prospective, IRB-approved, single-institution database was analyzed for all patients with anterior circulation aneurysms treated by flow diversion. The PED classic was used from August 2011 to January 2015, and the Pipeline Flex has been used since February 2015.RESULTSA total of 568 PED procedures (252 classic and 316 Flex) were performed for anterior circulation aneurysms. The average aneurysm size was 6.8 mm. Patients undergoing treatment with the Flex device had smaller aneurysms (p = 0.006) and were more likely to have undergone previous treatments (p = 0.001). Most aneurysms originated along the internal carotid artery (89% classic and 75% Flex) but there were more anterior cerebral artery (18%) and middle cerebral artery (7%) deployments with Flex (p = 0.001). Procedural success was achieved in 96% of classic and 98% of Flex cases (p = 0.078). Major morbidity or death occurred in 3.5% of cases overall: 5.6% of classic cases, and 1.9% of Flex cases (p = 0.019). On multivariate logistic regression, predictors of major complications were in situ thrombosis (OR 4.3, p = 0.006), classic as opposed to Flex device (OR 3.7, p = 0.008), and device deployment in the anterior cerebral artery or middle cerebral artery as opposed to the internal carotid artery (OR 3.5, p = 0.034).CONCLUSIONSFlow diversion of anterior circulation cerebral aneurysms is associated with an overall low rate of major complications. The complication rate is significantly lower since the introduction of the second-generation PED (Flex).
Quelques réflexions sur l'origine des bourrelets montagneux des marges passives
Authors: Birot Pierre 
Published: January 2018

In spite of the scarcity of geophysical data, we tried to design some models, accounting for the existence of continental bulges along the oceanic passive margins. They are usually isostasically compensated, either beneath the lithosphere by hot asthenospheric currents — either in the lower crust, which is difficult to reconcile with the spreading motions in extension.
In both cases, one must explain the fact that the uplift is periodically interrupted to allow the development of planation surfaces.
Les relations entre la ville et l'industrie : formes anciennes et formes nouvelles
Authors: Bruyelle Pierre , Dezert Bernard 
Published: January 2018

The recent évolution of the relations between towns and industries is often characterized by :
-the trend to the desindustrialization of the anciently industrialized towns and areas through the partial or total disappearance of old industries which leads to the decline of employment, of population, and demands somme efforts of conversions ;
-the transferring of industries, wholesale... that were before inside the towns, out of the towns into the suburbs or into the outer industrial areas ;
-the frequent settlement out of the towns of new industries, that even avoid the anciently industrialized towns or regions (except the industries for conversion) ;
-a spatial dissociation between industries and towns, which implies new spatial, functional, demographic... relations.
Industries are not generally the major impulse of urban growth any more ; the evolution of the structure of the enterprise into national or multinational firms tends to privilege a few urban poles of superior level, at the expense of middle sized or little towns.
In this evolution, the town has little power over the decision and the settlement of enterprise, and finances the potentialities of reception.
The urban organization that is inherited from the First Industrial Revolution is consequently taken up anew. But, how efficient can be a policy of re industrialization of ancient industrial towns, inside a more global policy of urban or regional planning ?

La politique des sites d'accueil d'activités par le F.I.B.M.
Les «sites d'accueil d'activités» sont l'un des cinq domaines d'intervention du F.I.B.M. (Fonds d'Industrialisation du Bassin Minier) créé en 1984.
Sont présentés des résultats d'une enquête portant sur trois années de programmes (84-85-86) et qui concernent :
L'immobilier d'entreprise pour lequel prédominent les formes traditionnelles de sa production, avec en marge quelques éléments d'innovation (diversification, technologie, architecture...). La localisation qui se partage entre des pratiques de séparation activités/résidence et le souci d'intégration dans l'urbanisme existant. La concertation entre entreprises et aménageurs.
Le dynamisme économique, avec une forte proportion de créations dans les emplois implantés. Tandis que les établissements transférés sont aussi importants que ceux créés sur place. Les activités en continuité avec le tissu existant vise plutôt une réponse quantitative à la situation locale de l'emploi.
Le F.I.B.M. favorise une pratique décentralisée portée par des «projets».

French Air Transport and the European Community.
January 1, 1993 is the date when air transport will be liberalized in the twelve European Community countries and that is likely to initiate considerable changes in Europe civil aviation. As the appointed day draws nearer French policy regarding air transport, the regulations applying to it and its predominantly nationalized structures must be totally reversed. Therefore, it is not surprising that even the step-by-step transition process stired up bitter clashes between the French Government and its state-owned company on the one part and the Commission and Court of the European Communauty on the other part.
Subsequent Nonthermal Emission Due to the Kilonova Ejecta in GW170817
Authors: Asano Katsuaki , To Sho 
Published: January 2018

Abstract
The ejected material at the binary neutron star merger GW170817 was confirmed as a kilonova by UV, optical, and IR observations. This event provides a unique opportunity to investigate the particle acceleration at a mildly relativistic shock propagating in the circumbinary medium. In this paper, we simulate the nonthermal emission from electrons accelerated by the shock induced by the kilonova ejecta with a time-dependent method. The initial velocity and mass of the ejecta in the simulations are obtained from the kilonova observations in GW170817. If the ambient density is high enough (≥10−2 cm−3), radio, optical/IR, and X-ray signals will be detected in a few years, though the off-axis short gamma-ray burst models, accounting for the X-ray/radio counterpart detected at ∼10 days after the merger, imply low ambient density. We also demonstrate that the additional low-mass (∼10−5
M
⊙) component with a velocity of 0.5c–0.8c can reproduce the early X-ray/radio counterpart. This alternative model allows a favorably high density to detect the nonthermal emission due to the kilonova ejecta. Even for a low ambient density such as ∼10−3 cm−3, depending on the microscopic parameters for the electron acceleration, we can expect a growth of radio flux of ∼0.1 mJy in a few years.

We present a spectroscopic redshift catalog from the LAMOST Complete Spectroscopic Survey of Pointing Area (LaCoSSPAr) in the Southern Galactic Cap (SGC), which is designed to observe all sources (Galactic and extragalactic) by using repeating observations with a limiting magnitude of

fields. The project is mainly focusing on the completeness of LAMOST ExtraGAlactic Surveys (LEGAS) in the SGC, the deficiencies of source selection methods, and the basic performance parameters of the LAMOST telescope. In both fields, more than 95% of galaxies have been observed. A post-processing has been applied to the LAMOST 1D spectrum to remove the majority of remaining sky background residuals. More than 10,000 spectra have been visually inspected to measure the redshift by using combinations of different emission/absorption features with an uncertainty of

. In total, 1528 redshifts (623 absorption and 905 emission line galaxies) in Field A and 1570 redshifts (569 absorption and 1001 emission line galaxies) in Field B have been measured. The results show that it is possible to derive redshift from low S/N galaxies with our post-processing and visual inspection. Our analysis also indicates that up to one-fourth of the input targets for a typical extragalactic spectroscopic survey might be unreliable. The multi-wavelength data analysis shows that the majority of mid-infrared-detected absorption (91.3%) and emission line galaxies (93.3%) can be well separated by an empirical criterion of

Published: January 2018

Abstract
We present the “Galaxy Cluster Merger Catalog.” This catalog provides an extensive suite of mock observations and related data for N-body and hydrodynamical simulations of galaxy cluster mergers and clusters from cosmological simulations. These mock observations consist of projections of a number of important observable quantities in several different wavebands, as well as along different lines of sight through each simulation domain. The web interface to the catalog consists of easily browsable images over epoch and projection direction, as well as download links for the raw data and a JS9 interface for interactive data exploration. The data are presented within a consistent format so that comparison between simulations is straightforward. All of the data products are provided in the standard Flexible Image Transport System file format. The data are being stored on the yt Hub (http://hub.yt), which allows for remote access and analysis using a Jupyter notebook server. Future versions of the catalog will include simulations from a number of research groups and a variety of research topics related to the study of interactions of galaxy clusters with each other and with their member galaxies. The catalog is located at http://gcmc.hub.yt.

Abstract
TCRs recognize peptides on MHC molecules and induce downstream signaling, leading to activation and clonal expansion. In addition to the strength of the interaction of TCRs with peptides on MHC molecules, mechanical forces contribute to optimal T cell activation, as reflected by the superior efficiency of immobilized TCR–cross-linking Abs compared with soluble Abs in TCR triggering, although a dedicated mechanotransduction module is not identified. We found that the professional mechanosensor protein Piezo1 is critically involved in human T cell activation. Although a deficiency in Piezo1 attenuates downstream events on ex vivo TCR triggering, a Piezo1 agonist can obviate the need to immobilize TCR–cross-linking Abs. Piezo1-driven Ca2+ influx, leading to calpain activation and organization of cortical actin scaffold, links this mechanosensor to optimal TCR signaling. Thus, we discovered a hitherto unknown regulatory mechanism for human T cell activation and provide the first evidence, to our knowledge, for the involvement of Piezo1 mechanosensors in immune regulation.
Rôle épidémiologique des diverses espèces animales dans la contamination rabique de l’Homme en Europe
Authors: Blancou J. , Barrat J. 
Published: January 2018

Après un rappel historique sur le développement et l’évolution des différents types de rage en Europe, les auteurs établissent les critères qui distinguent les espèces vectrices des espèces victimes dans l’épidémie.
Ils indiquent quel est le rôle joué dans la contamination de l’Homme par les espèces vectrices d’une part (ex. : Renard et Chien domestique dans l’Europe du Sud, mais aussi Chien viverrin et Chauve-souris) et par les espèces victimes de l’autre (ex. : Chien dans l’Europe du Nord, Chat, Herbivores).
Ces indications sont fondées sur des données biologiques précises concernant les espèces à l’origine de ces contaminations, la fréquence et le titre du virus réexcrété dans leurs glandes salivaires, etc.
Les auteurs concluent au moindre danger direct présenté pour l’Homme par les espèces sauvages mais au rôle important de relais joué par les espèces domestiques notamment les chiens et les herbivores.
Vaccinologie et vaccinovigilance

Le concept actuel de la Vaccinologie recouvre un champ d’étude vaste et complexe relatif à l’application individuelle et collective des vaccins dans ses implications techniques, immunologiques, épidémiologiques, sociales, juridiques, déontologiques et éthiques, et dans la mise en jeu des responsabilités du vaccinateur, de l’institut producteur et de l’Administration.
Il assure l’émergence de la vaccinovigilance, qui concerne les rares événements inattendus ou indésirables observés dans les conditions habituelles d’emploi des vaccins.
Ainsi se trouve justifiée la proposition d’un comité spécialisé, sous l’égide des quatre Académies (Médecine, Pharmacie, Vétérinaire et Agriculture), composé d’experts et de praticiens, qui permettrait la permanente actualisation des règles générales et spéciales de la Vaccinologie.
