syndrome (PRES) is a reversible syndrome accompanied by neurological and
radiological findings by Hynchy J et al. in 1996 . This syndrome is often referred with
hypertension, headache, confusion, convulsions, vomiting, and loss of vision.Two
hypotheses have been proposed for pathophysiology. The first being cerebral
hyperperfusion due to suddenly elevated blood pressure and the associated
vasogenic edema and the second endothelial dysfunction caused by endogenous and
exogenous toxins. It is clinically characterized by various neurological
findings which may develop acutely or subacutely. It can last for several hours or days and
weeks.Material
and method: This study was retrospectively performed between
Adiyaman University Faculty of Medicine Emergency Service between 2012-2017. Acute onset
neurological symptoms including headache, encephalopathy, seizure, visual impairment
or focal neurologic deficit, and five PRES cases with focal vasogenic edema on
brain imaging were included in the study. The cases were classified according to age, gender,
complaint of emergency service, chronic disease, pregnancy status, BBT, MR and
electroencephalographic (EEG) findings.Conclusion: As a result;
emergency headache, visual loss, loss of consciousness, and PRES in women and
pregnant women, especially those who are referred for convulsions.

This study aimed to identify The Youth Travel Characteristic, The Youth Travel Pattern and The Model of Youth Travel Pattern Development in Ambon island. This study used descriptive methods approach. Mean and frequencies are for analyzing respondents’ characteristics. Travel Pattern was analyzed by using GIS software. SWOT analysis was used to develop the Travel Pattern Model. The respondents were 100 youth travels at the age between 15 years - 30 years who visited Ambon City. The research sampling technique was convenience sampling. The questionnaires were distributed between June 2017 – July 2017. This study found that youth travelers who visited Ambon Island was dominated by young local tourists, under 26 years old, well educated, searched for cultural and social values. The main information sources during the trip were from friends or internet and they tend to plan their travel independently or with their family and friends rather then using travel agencies. The main trip driver is outdoor with leisure activities on the beach. This study also found out that security was the most influencing factor in determining travel itinerary of youth traveler. During the trip in Ambon Island, youth traveler was formed five travel pattern. The most travel pattern was formed by youth traveler was a single point. The study developed four youth travel pattern models to incrase the number of youth traveler visiting Ambon Island

Abstract
We present the molecular cloud properties of N55 in the Large Magellanic Cloud using 12CO(1–0) and 13CO(1–0) observations obtained with Atacama Large Millimeter Array. We have done a detailed study of molecular gas properties, to understand how the cloud properties of N55 differ from Galactic clouds. Most CO emission appears clumpy in N55, and molecular cores that have young stellar objects (YSOs) show larger linewidths and masses. The massive clumps are associated with high and intermediate mass YSOs. The clump masses are determined by local thermodynamic equilibrium and virial analysis of the 12CO and 13CO emissions. These mass estimates lead to the conclusion that (a) the clumps are in self-gravitational virial equilibrium, and (b) the 12CO(1–0)-to-H2 conversion factor,

, is 6.5 × 1020 cm−2 (K km s−1)−1. This CO-to-H2 conversion factor for N55 clumps is measured at a spatial scale of ∼0.67 pc, which is about two times higher than the

value of the Orion cloud at a similar spatial scale. The core mass function of N55 clearly show a turnover below 200

, separating the low-mass end from the high-mass end. The low-mass end of the 12CO mass spectrum is fitted with a power law of index 0.5 ± 0.1, while for 13CO it is fitted with a power law index 0.6 ± 0.2. In the high-mass end, the core mass spectrum is fitted with a power index of 2.0 ± 0.3 for 12CO, and with 2.5 ± 0.4 for 13CO. This power law behavior of the core mass function in N55 is consistent with many Galactic clouds.
Discriminaties bestrijden of diversiteit op de arbeidsmarkt promoten? Overzicht van een overheidsoptreden in het Brussels Hoofdstedelijk Gewest (1997-2012)
Authors: Tandé Alexandre 
Published: February 2018

Eind jaren 1990 treft het Brussels Hoofdstedelijk Gewest maatregelen in de strijd tegen discriminaties op de arbeidsmarkt op grond van etnische origine. In een sociohistorisch perspectief en op basis van mondelinge en geschreven bronnen schetst dit artikel de omstandigheden waarin dat overheidsbeleid tot stand komt, de experimentele acties van de eerste jaren en de wijziging van dat beleid in de jaren 2000. Tegelijk met zijn consolidatie (integratie van nieuwe maatregelen in het gewestelijk recht, oprichting van een Brusselse cel van diversiteitsconsultants) wordt het beleid tevens geheroriënteerd naar een nieuwe doelstelling: promotie van diversiteit. De strijd tegen discriminaties en de promotie van diversiteit worden weliswaar vaak voorgesteld als “de twee zijden van dezelfde medaille”, maar die twee doelstellingen kunnen ook een andere richting uitgaan of zelfs tegenstrijdig zijn. Een overzicht van de totstandkoming van dat Brussels beleid, van de evoluties en de impact ervan verstrekt dan toelichtingen bij de huidige antwoorden op twee grote uitdagingen in de Brusselse agglomeratie: de ongelijke toegang tot de arbeidsmarkt en de erkenning van de socioculturele diversiteit.
Marcinkiewicz Multipliers and Lipschitz Spaces on Heisenberg Groups
Authors: Han Yanchang , Han Yongsheng , Li Ji , Tan Chaoqiang 
Published: February 2018

AbstractThe Marcinkiewicz multipliers are
$L^{p}$
bounded for
$1<p<\infty$
on the Heisenberg group
$\mathbb{H}^{n}\simeq \mathbb{C}^{n}\times \mathbb{R}$
(Müller, Ricci, and Stein). This is surprising in the sense that these multipliers are invariant under a two parameter group of dilations on
$\mathbb{C}^{n}\times \mathbb{R}$
, while there is no two parameter group of automorphic dilations on
$\mathbb{H}^{n}$
. The purpose of this paper is to establish a theory of the flag Lipschitz space on the Heisenberg group
$\mathbb{H}^{n}\simeq \mathbb{C}^{n}\times \mathbb{R}$
that is, in a sense, intermediate between that of the classical Lipschitz space on the Heisenberg group
$\mathbb{H}^{n}$
and the product Lipschitz space on
$\mathbb{C}^{n}\times \mathbb{R}$
. We characterize this flag Lipschitz space via the Littlewood–Paley theory and prove that flag singular integral operators, which include the Marcinkiewicz multipliers, are bounded on these flag Lipschitz spaces.

AbstractChanging climate in northern regions is causing permafrost to thaw with major implications for the global mercury (Hg) cycle. We estimated Hg in permafrost regions based on in situ measurements of sediment total mercury (STHg), soil organic carbon (SOC), and the Hg to carbon ratio (RHgC) combined with maps of soil carbon. We measured a median STHg of 43 ± 30 ng Hg g soil−1 and a median RHgC of 1.6 ± 0.9 μg Hg g C−1, consistent with published results of STHg for tundra soils and 11,000 measurements from 4,926 temperate, nonpermafrost sites in North America and Eurasia. We estimate that the Northern Hemisphere permafrost regions contain 1,656 ± 962 Gg Hg, of which 793 ± 461 Gg Hg is frozen in permafrost. Permafrost soils store nearly twice as much Hg as all other soils, the ocean, and the atmosphere combined, and this Hg is vulnerable to release as permafrost thaws over the next century. Existing estimates greatly underestimate Hg in permafrost soils, indicating a need to reevaluate the role of the Arctic regions in the global Hg cycle.
Turbulent Kinematic Dynamos in Ellipsoids Driven by Mechanical Forcing
Authors: Reddy K. Sandeep , Favier Benjamin , Le Bars Michael 
Published: February 2018

AbstractDynamo action in planetary cores has been extensively studied in the context of convectively driven flows. We show in this letter that mechanical forcings, namely, tides, libration, and precession, are also able to kinematically sustain a magnetic field against ohmic diffusion. Previous attempts published in the literature focused on the laminar response or considered idealized spherical configurations. In contrast, we focus here on the developed turbulent regime and we self‐consistently solve the magnetohydrodynamic equations in an ellipsoidal container. Our results open new avenues of research in dynamo theory where both convection and mechanical forcing can play a role, independently or simultaneously.
On the Nocturnal Downward and Westward Equatorial Ionospheric Plasma Drifts During the 17 March 2015 Geomagnetic Storm

Published: February 2018

AbstractDuring quiet period, the nocturnal equatorial ionospheric plasma drifts eastward in the zonal direction and downward in the vertical direction. This quiet time drift pattern could be understood through dynamo processes in the nighttime equatorial ionosphere. The present case study reports the nocturnal simultaneous occurrence of the vertically downward and zonally westward plasma drifts over the Indian latitudes during the geomagnetic storm of 17 March 2015. After ~17:00 UT (~22:10 local time), the vertical plasma drift became downward and coincided with the westward zonal drift, a rarely observed feature of low latitude plasma drifts. The vertical drift turned upward after ~18:00 UT, while the zonal drift became eastward. We mainly emphasize here the distinct bipolar type variations of vertical and zonal plasma drifts observed around 18:00 UT. We explain the vertical plasma drift in terms of the competing effects between the storm time prompt penetration and disturbance dynamo electric fields. Whereas, the westward drift is attributed to the storm time local electrodynamical changes mainly through the disturbance dynamo field in addition to the vertical Pedersen current arising from the spatial (longitudinal) gradient of the field aligned Pedersen conductivity.
Variations of the Electron Fluxes in the Terrestrial Radiation Belts Due To the Impact of Corotating Interaction Regions and Interplanetary Coronal Mass Ejections
Authors: Benacquista R. , Boscher D. , Rochel S. , Maget V. 
Published: February 2018

AbstractIn this paper, we study the variations of the radiation belts electron fluxes induced by the interaction of two types of solar wind structures with the Earth magnetosphere: the corotating interaction regions and the interplanetary coronal mass ejections. We use a statistical method based on the comparison of the preevent and postevent fluxes. Applied to the National Oceanic and Atmospheric Administration‐Polar Operational Environmental Satellites data, this gives us the opportunity to extend previous studies focused on relativistic electrons at geosynchronous orbit. We enlighten how corotating interaction regions and Interplanetary Coronal Mass Ejections can impact differently the electron belts depending on the energy and the L shell. In addition, we provide a new insight concerning these variations by considering their amplitude. Finally, we show strong relations between the intensity of the magnetic storms related to the events and the variation of the flux. These relations concern both the capacity of the events to increase the flux and the deepness of these increases.

AbstractNew ionosphere and electrodynamics modules have been incorporated in the thermosphere and ionosphere eXtension of the Whole Atmosphere Community Climate Model (WACCM‐X), in order to self‐consistently simulate the coupled atmosphere‐ionosphere system. The first specified dynamics WACCM‐X v.2.0 results are compared with several data sets, and with the Thermosphere‐Ionosphere‐Electrodynamics General Circulation Model (TIE‐GCM), during the deep solar minimum year. Comparisons with Thermosphere Ionosphere Mesosphere Energetics and Dynamics satellite of temperature and zonal wind in the lower thermosphere show that WACCM‐X reproduces the seasonal variability of tides remarkably well, including the migrating diurnal and semidiurnal components and the nonmigrating diurnal eastward propagating zonal wavenumber 3 component. There is overall agreement between WACCM‐X, TIE‐GCM, and vertical drifts observed by the Communication/Navigation Outage Forecast System (C/NOFS) satellite over the magnetic equator, but apparent discrepancies also exist. Both model results are dominated by diurnal variations, while C/NOFS observed vertical plasma drifts exhibit strong temporal variations. The climatological features of ionospheric peak densities and heights (NmF2 and hmF2) from WACCM‐X are in general agreement with the results derived from Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC) data, although the WACCM‐X predicted NmF2 values are smaller, and the equatorial ionization anomaly crests are closer to the magnetic equator compared to COSMIC and ionosonde observations. This may result from the excessive mixing in the lower thermosphere due to the gravity wave parameterization. These data‐model comparisons demonstrate that WACCM‐X can capture the dynamic behavior of the coupled atmosphere and ionosphere in a climatological sense.
Breakpoint Forcing Revisited: Phase Between Forcing and Response
Authors: Contardo S. , Symonds G. , Dufois F. 
Published: February 2018

AbstractUsing the breakpoint forcing model, for long wave generation in the surf zone, expressions for the phase difference between the breakpoint‐forced long waves and the incident short wave groups are obtained. Contrary to assumptions made in previous studies, the breakpoint‐forced long waves and incident wave groups are not in phase and outgoing breakpoint‐forced long waves and incident wave groups are not π out of phase. The phase between the breakpoint‐forced long wave and the incident wave group is shown to depend on beach geometry and wave group parameters. The breakpoint‐forced incoming long wave lags behind the wave group, by a phase smaller than π/2. The phase lag decreases as the beach slope decreases and the group frequency increases, approaching approximately π/16 within reasonable limits of the parameter space. The phase between the breakpoint‐forced outgoing long wave and the wave group is between π/2 and π and it increases as the beach slope decreases and the group frequency increases, approaching 15π/16 within reasonable limits of the parameter space. The phase between the standing long wave (composed of the incoming long wave and its reflection) and the incident wave group tends to zero when the wave group is long compared to the surf zone width. These results clarify the phase relationships in the breakpoint forcing model and provide a new base for the identification of breakpoint forcing signal from observations, laboratory experiments and numerical modeling.
On the Decrease of the Oceanic Drag Coefficient in High Winds
Authors: Donelan Mark A. 
Published: February 2018

AbstractThe sheltering coefficient – prefixing Jeffreys' concept of the exponential wave growth rate at a gas‐liquid interface – is shown to be Reynolds number dependent from laboratory measurements of waves and Reynolds stresses. There are two turbulent flow regimes: wind speed range of 2.5 to 30 m/s where the drag coefficients increase with wind speed, and wind speed range of 30 to 50 m/s where sheltering/drag coefficients decrease/saturate with wind speed. By comparing model calculations of drag coefficients – using a fixed sheltering coefficient – with ocean observations over a wind speed range of 1 to 50 m/s a similar Reynolds number dependence of the oceanic sheltering coefficient is revealed. In consequence the drag coefficient is a function of Reynolds number and wave age, and not just wind speed as frequently assumed. The resulting decreasing drag coefficient above 30 m/s is shown to be critical in explaining the rapid intensification so prominent in the climatology of Atlantic hurricanes. The Reynolds number dependence of the sheltering coefficient, when employed in coupled models, should lead to significant improvements in the prediction of intensification and decay of tropical cyclones. A calculation of curvature at the wave crest suggests that at wind speeds above 56.15 m/s all waves––breaking or not––induce steady flow separation leading to a minimum in the drag coefficient. This is further evidence of the veracity of the observations of the oceanic drag coefficient at high winds.
Reconstruction of the 3‐D Dynamics From Surface Variables in a High‐Resolution Simulation of North Atlantic
Authors: Fresnay S. , Ponte A. L. , Le Gentil S. , Le Sommer J. 
Published: February 2018

AbstractSeveral methods that reconstruct the three‐dimensional ocean dynamics from sea level are presented and evaluated in the Gulf Stream region with a 1/60° realistic numerical simulation. The use of sea level is motivated by its better correlation with interior pressure or quasi‐geostrophic potential vorticity (PV) compared to sea surface temperature and sea surface salinity, and, by its observability via satellite altimetry. The simplest method of reconstruction relies on a linear estimation of pressure at depth from sea level. Another method consists in linearly estimating PV from sea level first and then performing a PV inversion. The last method considered, labeled SQG for surface quasi‐geostrophy, relies on a PV inversion but assumes no PV anomalies. The first two methods show comparable skill at levels above −800 m. They moderately outperform SQG which emphasizes the difficulty of estimating interior PV from surface variables. Over the 250–1,000 m depth range, the three methods skillfully reconstruct pressure at wavelengths between 500 and 200 km whereas they exhibit a rapid loss of skill between 200 and 100 km wavelengths. Applicability to a real case scenario and leads for improvements are discussed.
