STUDI EKSPERIMEN OIL FLOW VISUALIZATION PADA AIRFOIL NACA 0012 DENGAN TRAPEZOIDAL VORTEX GENERATOR MENGGUNAKAN OPEN CIRCUIT SUBSONIC WIND TUNNEL
Authors: Hariyadi Setyo , Aldo putra Habibie 
Published: May 2020

Pada pembuatan suatu pesawat terbang, suatu analisis sebelum terbang terhadap kinerja aerodinamika dari pesawat tersebut sangat diperlukan, terutama untuk daerah dimana metoda analitik/empirik tidak dapat menjangkaunya seperti perkiraan CLmax, karakteristik stall dan lain-lainnya. Satu hal penting yang harus diperhatikan dalam pendesainan suatu pesawat yaitu pemilihan airfoil dan modifikasinya. Modifikasi airfoil dilakukan untuk menunda separasi aliran dan meningkatkan performa airfoil, salah satunya dengan vortex generator. Hal ini dapat diindikasikan dengan tertundanya separasi aliran yang melintasi permukaan atas dari airfoil.
Topik yang dikaji dalam penelitian ini adalah aliran melintasi airfoil NACA 0012 dengan penambahan vortex generator. Tujuan penelitian ini adalah untuk membandingkan karakteristik aliran fluida dengan dan tanpa penambahan vortex generator. Profil vortex generator yang digunakan adalah trapezoidal vortex generator dengan konfigurasi straight dan ditempatkan pada x/c = 20% arah chord line dari leading edge. Variasi yang digunakan adalah bilangan Reynolds (Re) dan sudut serang (α) pada airfoil. Kecepatan freestream yang digunakan yaitu kecepatan 10 m/s dan 20 m/s, pada sudut serang (α) 0°, 4°, 10°, 12°, 15°,dan 17°.
Dari penelitian ini didapatkan performa aerodinamika dan fenomena aliran di sekitar airfoil. Perihal ini ada peningkatan performa aerodinamika pesawat dari sudut serang 0° sampai sudut serang 12° terbukti dengan meningkatnya kecepatan transisi dari laminar boundary layer menjadi turbulent boundary layer.

Published: May 2020

We report results of computational study of a newly designed cyanidin based molecular structure, P02, as efficient sensitizers for dye sensitized solar cells (DSSCs). To design this P02, widely used promising natural dye sensitizer cyanidin [1] is combined with α-cyanocinnamic acid and the resultant structure is computationally simulated by using SPARTAN’10 software package [2].The moleculer geometries, electronic structures, absorption spectra and deprotonation enengies of newely designed organic sensitizer are investigated through density functional theory(DFT) and time-dependent density functional theory(TDDFT) approach using GAUSSIAN’09W software package [3]. Furthermore DFT and TDDFT computational calculations are performed on cyanadin too, as reference. The solvation effect in ethanol are included in all calculations.The computational studies on the new dye have shown broadening of the absorption spectra in visible region with significant shifting towards a longer wavelength compared to the cyanidin. Our computational study results indicated that the new dye P02 should exhibit better performance as a sensitizer due to its improved optical properties.
Comparison of generalized non-data-driven lake and reservoir routing models for global-scale hydrologic forecasting of reservoir outflow at diurnal time steps
Authors: Gutenson Joseph L. , Tavakoly Ahmad A. , Wahl Mark D. , Follum Michael L. 
Published: May 2020

Abstract. Large-scale hydrologic forecasts should account for attenuation
through lakes and reservoirs when flow regulation is present. Globally
generalized methods for approximating outflow are required but must contend
with operational complexity and a dearth of information on dam
characteristics at global spatial scales. There is currently no consensus on
the best approach for approximating reservoir release rates in large spatial
scale hydrologic forecasting, particularly at diurnal time steps. This
research compares two parsimonious reservoir routing methods at daily steps: Döll et al. (2003) and Hanasaki et al. (2006). These reservoir routing
methods have been previously implemented in large-scale hydrologic modeling
applications and have been typically evaluated seasonally. These routing
methods are compared across 60 reservoirs operated by the U.S. Army Corps of
Engineers. The authors vary empirical coefficients for both reservoir
routing methods as part of a sensitivity analysis. The method proposed by
Döll et al. (2003) outperformed that presented by Hanasaki et al. (2006)
at a daily time step and improved model skill over most run-of-the-river
conditions. The temporal resolution of the model influences model
performances. The optimal model coefficients varied across the reservoirs in
this study and model performance fluctuates between wet years and dry years,
and for different configurations such as dams in series. Overall, the method
proposed by Döll et al. (2003) could enhance large-scale hydrologic
forecasting, but can be subject to instability under certain conditions.
Very high-resolution modelling of submesoscale turbulent patterns and processes in the Baltic Sea
Authors: Onken Reiner , Baschek Burkard , Angel-Benavides Ingrid M. 
Published: May 2020

Abstract. In order to simulate submesoscale turbulent patterns and processes
(STPPs) and to analyse their properties and dynamics, the Regional
Ocean Modeling System (ROMS) was run for June 2016 in a subregion of
the Baltic Sea. To create a realistic mesoscale environment, ROMS with
500 m horizontal resolution (referred to as R500) is one-way nested
into an existing operational model, and STPPs with horizontal scales
<1 km are resolved with a second nest of 100 m resolution
(R100). Both nests use 10 terrain-following layers in the vertical.
The comparison of the R500 results with a satellite image shows fair
agreement. While R500 is driven by realistic air–sea fluxes, the
atmospheric forcing is turned off in R100 because it prevents the
generation of STPPs and blurs submesoscale structures. Therefore, R100
provides deep insight into ageostrophic processes and associated
quantities under quasi-adiabatic conditions that are approximately met
in no-wind or light-wind situations. The validity of the results is
furthermore limited to the selected region and the time of the year.
STPPs evolve rapidly within a about a day. They are characterized by
vertical speeds of 𝒪(10) m d−1 and relative vorticities
and divergences reaching multiples of the Coriolis parameter. Typical
elements of the secondary circulation of two-dimensional
strain-induced frontogenesis are identified at an exemplary front in
shallow water, and details of the ageostrophic flow field are
revealed. The conditions for inertial and symmetric instability are
evaluated for the whole domain, and the components of the tendency
equation are computed in a subregion. While anticyclonic eddies are
generated solely along coasts, cyclonic eddies are rolled-up streamers
and found in the entire domain. A special feature of the cyclones is
their ability to absorb internal waves and to sustain patches of
continuous upwelling for several days, favouring plankton growth. The
kinematic properties show good agreement with observations, while some
observed details within a small cyclonic eddy are only partly
reproduced, most likely due to a lack of horizontal resolution or
nonhydrostatic effects.

Abstract. Today, coastal cities worldwide are facing major changes
resulting from climate change and anthropogenic forcing, which requires
adaptation and mitigation strategies to be established. In this context,
sedimentological archives in many Mediterranean cities record a
multi-millennial history of environmental dynamics and human adaptation,
revealing a long-lasting resilience. Founded by the Phoenicians around 3000 years ago, Cádiz (south-western Spain) is a key example of a coastal
resilient city. This urban centre is considered to be one of the first
cities of western Europe and has experienced major natural hazards during its
long history, such as coastal erosion, storms, and also tsunamis (like the
one in 1755 CE following the destructive Lisbon earthquake). In the framework of an international, joint archaeological and
geoarchaeological project, three cores have been drilled in a marine
palaeochannel that ran through the ancient city of Cádiz. These
cores reveal a ≥50 m thick Holocene sedimentary sequence. Importantly,
most of the deposits date from the 1st millennium BCE to the 1st
millennium CE. This exceptional sedimentary archive will allow our
scientific team to achieve its research goals, which are (1) to reconstruct
the palaeogeographical evolution of this specific coastal area; (2) to trace
the intensity of activities of the city of Cádiz based on archaeological
data, as well as geochemical and palaeoecological indicators; and (3) to
identify and date high-energy event deposits such as storms and tsunamis.
Langage et Travail: une dynamique de « double anticipation » pour la formation professionnelle

En formation professionnelle, la question se pose du retour d’expérience. Qu’est-ce que nous apprend le travail, non seulement en termes de savoirs à mobiliser dans l’action, mais aussi dans la gestion des épreuves au moment d’agir, quand il faut tenir compte de ce qui vient d’arriver et de ce qui s’annonce, des initiatives que les autres sont en train de prendre, des enjeux de l’action collective, des risques que l’on doit soi-même assumer en responsabilité ?Pour rendre compte de toute cette richesse, il faut comprendre pourquoi il est si difficile de « dire son travail » et imaginer un dispositif capable d’inciter chacun à se prêter à l’exercice. C’est le double objectif du présent article.
Safeguarding the Dynamic Legal Position of Children: A Matter of Age Limits?

Safeguarding the Dynamic Legal Position of Children: A Matter of Age Limits?
In this article a critical reflection upon age limits applied in the law is provided, in light of the tension that exists in international children’s rights law between the protection of children and the recognition of their evolving autonomy. The main research question that will be addressed is to what extent the use of (certain) age limits is justified under international children’s rights law. The complexity of applying open norms and theoretically underdeveloped concepts as laid down in the UN Convention on the Rights of the Child, related to the development and evolving capacities of children as rights holders, will be demonstrated. The UN Committee on the Rights of the Child struggles to provide comprehensive guidance to states regarding the manner in which the dynamic legal position of children should be applied in practice. The inconsistent application of age limits that govern the involvement of children in judicial procedures provides states leeway in granting children autonomy, potentially leading to the establishment of age limits based on inappropriate – practically, politically or ideologically motivated – grounds.

Gewezen EU-werknemer behoudt verblijfsrecht bij werkloosheid na twee weken werken
In deze zaak geeft het Hof van Justitie voor het eerst uitleg aan artikel 7 lid 3 onder c Richtlijn 2004/38/EG. De taalkundige onduidelijkheid in deze bepaling leidde in de zaak Tarola tot de vraag of een werknemer die na twee weken te hebben gewerkt onvrijwillig werkloos wordt, de status als werknemer behoudt. Het Hof van Justitie antwoordt hier bevestigend op waarbij nog eens wordt bevestigd dat het Hof van Justitie streeft naar een interpretatie van het begrip werknemer waar zo veel mogelijk personen onder vallen.HvJ 11 april 2019, zaak C-483/17, ECLI:EU:C:2019:309 (Neculai Tarola/Minister for Social Protection)

De ACM leidraad tariefafspraken zzp’ers: de ACM vs. Europees kartelverbod?
Met de publicatie van de Leidraad tariefafspraken zzp’ers beoogt de Autoriteit Consument & Markt (ACM) duidelijkheid te scheppen over de verenigbaarheid van zulke afspraken met het mededingingsrecht. Aangezien zzp’ers in de regel worden gezien als onderneming, vallen onderlinge afspraken over prijzen in beginsel onder het kartelverbod. De ACM signaleert de zorg dat zzp’ers door concurrentie onder het bestaansminimum uitkomen. Zij heeft in de Leidraad drie volgens haar toepasselijke uitzonderingen op het kartelverbod geformuleerd. Daarnaast kondigt de ACM aan het kartelverbod niet te zullen handhaven ten aanzien van afspraken die het door het kabinet beoogde minimumloon voor zzp’ers van 16 euro per uur vastleggen. Of dit minimumloon er komt en wat het voor deze toezegging betekent als dit niet het geval is, zal moeten blijken.Artikel 6 Mededingingswet en artikel 101 Verdrag betreffende de Werking van de Europese Unie

Beperkingen van het verblijfsrecht van EU-burgers en hun familieleden in de lidstaten van de EU: Uit het oog, maar niet uit het hart?
Het recht van vrij verkeer en verblijf van EU-burgers en hun familieleden in de EU wordt geregeld door de Burgerschapsrichtlijn. Dit recht is echter niet absoluut en kan worden geweigerd of ingetrokken wanneer een EU-burger onvoldoende inkomsten heeft om voor zichzelf en voor zijn familie te zorgen. Familieleden die geen EU-nationaliteit bezitten, hebben een recht om te verblijven in een gastlidstaat, wanneer zij hun familielid, die EU-burger is, begeleiden of zich bij deze EU-burger voegen. In de twee zaken die in dit artikel centraal staan, worden deze twee voorwaarden voor het verblijfsrecht van EU-burgers en hun familieleden door het Hof van Justitie nader uitgelegd.HvJ 2 oktober 2019, zaak C-93/18, ECLI:EU:C:2019:809 (Ermira Bajratari/Secretary of State for the Home Department)HvJ 10 september 2019, zaak.

Una mirada a una ciudad sin planificación: patrones en la forma de los barrios informales en la ciudad de Manta, Ecuador
Authors: Pico Alonso Karen 
Published: May 2020

En Ecuador distinguimos cuatro periodos en los que se desencadenan procesos migratorios importantes. En éstos adquieren protagonismo formas de ocupación heterodoxas, respondiendo a la urgente necesidad de vivienda y desencadenando un proceso de expansión urbana incontrolada en distintas ciudades del país. En Manta esta expansión se da principalmente en el lado suroriente con la aparición de “invasiones”, que fueron fomentadas por el clientelismo mediante la autoconstrucción y el fraccionamiento del suelo al margen de la legislación. Ante un desarrollo urbano donde predominaron las iniciativas individuales, que acabaron pautando el crecimiento y la orientación del trazado urbano, cabría una mirada pertinente para hallar un orden y unos patrones en la composición del plano irregular, y comprender las “reglas” de este fenómeno.
In Ecuador we identify four periods in which important migratory processes are triggered. In these, forms of heterodox occupation take center stage, responding to the urgent need for housing and unleashing a process of uncontrolled urban expansion in different cities of the country. In Manta, we observe this expansion mainly on the southeastern side, composed of several "invasions" promoted by political clientelism through self-construction and fractioning of the land outside the legislation. In the face of such growth, dominated byindividual initiatives that ended up regulating the development and orientation of the urban layout, a more adequate look should be taken to find order and patterns within this irregular plane, and to understand the "rules" of this phenomenon.
Más allá del Agua: desarrollo urbano de la Comarca Lagunera México después de la regulación del río Nazas
Authors: Barrios Avalos Juan José 
Published: May 2020

Las tres ciudades principales en la Comarca Lagunera; Torreón, Gómez Palacio, y Lerdo, se emplazan sobreel curso bajo del río Nazas en el semi-desierto del noroeste mexicano. Entre 1946 y 1968 se construyen, una serie de presas y canales para regular el caudal del río. Este sistema de regulación permitió administrar el aguapara riego agrícola, reducir las inundaciones en zonas anegables en la ribera y proporcionar agua potable a las ciudades de la Comarca. Sin embargo, también propició la desaparición de la corriente de agua en el cursobajo del río en la ribera de las tres ciudades, y la desecación de la Laguna de Mayrán en la desembocadura del Nazas. En este sentido se observa que, el sistema de regulación también alteró y condicionó hasta hoy en día, las lógicas de desarrollo urbano de Torreón, Gómez Palacio y Lerdo y su relación paisajística con el territorio.
Comarca Lagunera’s three major cities are Torreon, Gomez Palacio, and Lerdo. All three cities are located in the downstream course of the Nazas River in the semi-desert of the Mexican northwest. In order to regulate the flow of the Nazas River, a series of dams and canals were built over a twenty year period between 1946and 1968. The system permitted the administration of water for agricultural irrigation, the reduction of floodingin floodplain areas on riverbanks, and access to drinking water for local populations. Unfortunately,consequences of this system included water recession in the downstream course of the riverbanks in thesethree cities, and the drying of Mayran’s Lagoon at the mouth of the Nazas. Urban growth of Torreon, GomezPalacio, and Lerdo was permanently altered, as was the cities’ landscape relationship with the territory — a direct result of the construction of this regulation system.
Súper-diversidad y comercio local: las huellas de la gentrificación y de la migración transnacional en el centro de Santiago
Authors: Catalán Hidalgo René 
Published: May 2020

La presente investigación aborda las transformaciones materiales de los espacios comerciales del centro de Santiago, a partir del concepto de súper-diversidad. Hablar de súper-diversidad en una ciudad del Sur Global como Santiago, implica incluir los fenómenos de gentrificación y de migración transnacional, siendo ellos y su desarrollo en la ciudad, claves para comprender un proceso reciente como el de la súper-diversificación. Para lograr este fin, se creó el Indicador de Potencial de Gentrificación el que permitió identificar la zona específica de Santiago, que corresponde a un polígono del Barrio Lira, el cual se abordó en la segunda etapa. Posteriormente se empleó análisis visual con fotografías tomadas en el barrio e imágenes obtenidas desde Google Street View, contraste que permite analizar las transformaciones recientes de los espacios comerciales de la zona seleccionada, de una perspectiva de la súper-diversificación de la ciudad de Santiago.
This research addresses the material transformations of the commercial spaces of the center of Santiago, using the concept of super-diversity. Talking about super-diversity in a city of the Global South such as Santiago, involves including the phenomena of gentrification and transnational migration, being these concepts and their development in the city, keys to understanding a recent process such as super-diversification. To achieve this aim, the Gentrification Potential Indicator was developed, these allowed the identification of the specific area of Santiago to be addressed in the second stage, which corresponds to a polygon of the Lira Neighborhood. Subsequently, visual analysis was used with photographs taken in the neighborhood and images obtained from Google Street View, a contrast that allows the analysis of recent transformations of the commercial spaces of the selected area, from a perspective of the super-diversification of the city of Santiago.
Updates to Medicare's Quality Payment Program That May Impact You
Authors: Cardona Diana M. , Peditto Stephanie , Singh Loveleen , Black-Schaffer Stephen 
Published: May 2020

Context.—
Within Medicare's Quality Payment Program, and more specifically the Merit-based Incentive Payment System, pathologists stand to potentially lose or gain approximately $2 billion during the initial 7 years of the program. If you or your group provides services to Medicare beneficiaries, you will likely need to comply with the program.

Objective.—
To avoid potential reductions in Medicare reimbursement, pathologists need to understand the requirements of these new payment programs.

Data Sources.—
Each year the Centers for Medicare & Medicaid Services publish a Final Rule detailing the program requirements and updates. 2020 marks the fourth reporting year for the Merit-based Incentive Payment System. Performance this year will impact 2022 Medicare Part B distributions by up to ±9%.

Conclusions.—
By staying up to date with the ever-evolving Merit-based Incentive Payment System requirements, pathologists will be better equipped to successfully comply with this relatively new payment system, reduce the burden of participating, understand the reporting differences of the various performance categories, and thereby be able to maximize their scoring and incentive potential.
Developing Pathology Measures for the Quality Payment Program—Part II: Overcoming Challenges With Data Capture to Maximize Reimbursement
Authors: Kelley James , Patil Pallavi , Kennedy Angela , Singh Loveleen , Peditto Stephanie , Cardona Diana M. 
Published: May 2020

Context.—
Quality measures are a cornerstone in measuring physicians' performance within the Centers for Medicare & Medicaid Services' Quality Payment Program (QPP). Clinicians' performance on quality measures and other categories within the QPP determines Medicare part B payment adjustments. Driven by evidence-based clinical practice guidelines, quality measures should focus on high-priority facets of health care, support a desired patient outcome, and address an area with evidence of a gap or variation in provider performance.

Objective.—
To meet the goals of the QPP, a broad array of quality measures must be developed that allows pathologists the flexibility to choose activities and measures most meaningful to their practice and patient population while also trying to mitigate the challenges of implementation and data collection.

Design.—
In this second manuscript of the series, we present the development of additional College of American Pathologists–developed quality payment measures for use in the QPP. We also discuss the relationship of quality measure reporting with reimbursement and the challenges with capturing data for quality reporting.

Results.—
The College of American Pathologists identified 23 new measures for quality performance reporting that reflect rigorous clinical evidence and address areas in need of performance improvement.

Conclusions.—
Development of quality measures is a necessary and ongoing effort within the College of American Pathologists. Increased awareness about pathology-specific issues in measure development and reporting is essential to ensuring pathology's ability to demonstrate value and meaningfully participate in the QPP.
