Diabetes Melitus merupakan penyakit metabolik kronis tidak menular, dengan karakteristik hiperglikemi yang terjadi karena kelainan sekresi insulin, kerja insulin atau keduanya yang tidak dapat disembuhkan tetapi dapat dikendalikan. Kadar gula darah merupakan kadar glukosa dalam darah dengan nilai >126 mg/dl dalam keadaan puasa dinyatakan kadar gula darah tinggi/kencing manis yang juga sering disebut Diabetes Melitus (Corwin, 1997). Kadar gula darah yang tinggi dan berlangsung lama dapat menimbulkan komplikasi yaitu kelainan mikrovaskuler seperti retinopati, nefropati, jantung koroner dan kelainan makrovaskuler seperti stroke, jantung sistemik dan gangren. Komplikasi diabetes dapat mengenai berbagai organ tubuh dan jaringan diantaranya adalah kerusakan ginjal yang ditandai dengan adanya albumin urin karena penurunan filtrasi glomerulus ginjal dan gangguan respon imunitas. Kondisi kadar gula darah melebihi normal memicu terjadinya peningkatan radikal bebas pada berbagai sel tubuh termasuk jumlah sel neutrofil (Tjokoprawiro, 2006). Kegiatan pengabdian pada masyarakat ini berupa penyuluhan tentang, faktor risiko penyakit diabetes melitus, tanda dan gejala penyakit diabetes melitus serta pengaturan intake makanan yang mengandung gula bagi setiap masyarakat yang memiliki risiko untuk terjadinya Penyakit diabetes melitus dan bagi masyarakat yang menderita diabetes melitus. Selain itu juga dilakukan penyuluhan tentang penggunaan alat “glukosa-test” untuk memeriksa kadar gula darah sewaktu kepada masyarakat Kelurahan Aryo Kemuning, Siring Agung, pemeriksaan kadar glukosa darah sewaktu dan konsultasi sekitar penyakit diabetes melitus.

Polytropic Behavior of Solar Wind Protons Observed by Parker Solar Probe
Authors: Nicolaou Georgios , Livadiotis George , Wicks Robert T. , Verscharen Daniel , Maruca Bennett A. 
Published: September 2020

Abstract
A polytropic process describes the transition of a fluid from one state to another through a specific relationship between the fluid density and temperature. The value of the polytropic index that governs this relationship determines the heat transfer and the effective degrees of freedom during a specific process. In this study, we analyze solar wind proton plasma measurements, obtained by the Faraday cup instrument on board the Parker Solar Probe. We examine the large-scale variations of the proton plasma density and temperature within the inner heliosphere explored by the spacecraft. We then address the polytropic behavior in the density and temperature fluctuations in short time intervals, which we analyze in order to derive the effective polytropic index of small-scale processes. The large-scale variations of the solar wind proton density and temperature, which are associated with the plasma expansion into the heliosphere, follow a polytropic model with a polytropic index ∼5/3. On the other hand, the short-scale fluctuations, which are potentially associated with turbulence, follow a model with a larger polytropic index. We investigate possible correlations between the polytropic index of short-scale fluctuations and the plasma speed, plasma β, and the magnetic field direction. We discuss candidate mechanisms leading to this behavior including energy transfer and possible mechanisms restricting the effective particle degrees of freedom at smaller scales.

Abstract
For the active T-Taur star RW Aur A we have performed long-term (∼10 yr) monitoring observations of (1) jet imaging in the [Fe II] 1.644 μm emission line using Gemini-NIFS and VLT-SINFONI; (2) optical high-resolution spectroscopy using CFHT-ESPaDOnS; and (3) V-band photometry using the CrAO 1.25-m telescope and AAVSO. The latter two observations confirm the correlation of time variabilities between (A) the Ca II 8542 Å and O I 7772 Å line profiles associated with magnetospheric accretion, and (B) optical continuum fluxes. The jet images and their proper motions show that four knot ejections occurred at the star over the past ∼15 yr with an irregular interval of 2–6 yr. The timescale and irregularity of these intervals are similar to those of the dimming events seen in the optical photometry data. Our observations show a possible link between remarkable (ΔV < −1) photometric rises and jet knot ejections. Observations over another few years may confirm or reject this trend. If confirmed, this would imply that the location of the jet launching region is very close to the star (r ≲ 0.1 au) as predicted by some jet launching models. Such a conclusion would be crucial for understanding disk evolution within a few astronomical units of the star, and therefore possible ongoing planet formation at these radii.

Abstract
Recent analysis of the second data release of Gaia has revealed a number of new stellar streams surrounding the Milky Way. It has been suggested that one of these streams, Gjöll, is associated with the globular cluster NGC 3201, but thus far the association has only been based on kinematics of the stream stars. In this work we identify five likely stream members in the Gaia data that are bright enough for high-resolution spectroscopic follow-up with the Harlan J. Smith telescope at McDonald Observatory. One star is ruled out as a member based on its radial velocity. Abundance analysis of the remaining four kinematic members reveals a good chemical match to NGC 3201 for two of the stars, driven by their similar Al and α-element abundances. Of the remaining two, one shows no chemical similarity to NGC 3201 and is likely an unassociated Milky Way halo field star, while the other exhibits a similar Al abundance but has somewhat lower α-element abundances. The chemical tagging of stars in the Gjöll stream to NGC 3201 confirms this association and provides direct proof of the hierarchical formation of the Milky Way.

Abstract
We report a search for the diatomic hydrides SiH, PH, and FeH along the line of sight toward the chemically rich circumstellar envelopes of IRC+10216 and VY Canis Majoris. These molecules are thought to form in high-temperature regions near the photospheres of those stars, and may then further react via gas-phase and dust-grain interactions leading to more complex species, but have yet to be constrained by observation. We used the German Receiver for Astronomy at Terahertz Frequencies spectrometer on the Stratospheric Observatory for Infrared Astronomy to search for rotational emission lines of these molecules in four spectral windows ranging from 600 to 1500 GHz. Although none of the targeted species was detected in our search, we report their upper limit abundances in each source and discuss how they influence the current understanding of hydride chemistry in dense circumstellar media. We attribute the nondetections of these hydrides to their compact source sizes, high barriers of formation, and proclivity to react with other molecules in the winds.

Published: September 2020

Abstract
The detection of biosignatures on a planetary surface is of high scientific interest, and enantiomeric excesses of organic molecules are one such signature. Enantiomeric excesses can be detected by their polarizing effects on transmitted light. As part of instrument development work for a microscopic imager, the Cold Lightweight Imager for Europa (C-LIFE), we assess the potential of polarization measurements to quantify enantiomeric excesses. We investigated the optical rotation of the amino acids serine and phenylalanine for a range of enantiomeric abundances. Measurements were made with mixtures of serine and phenylalanine as well as Europa-relevant salts to determine how well these combinations can be detected. We also conducted a small number of measurements on samples of bacteria taken from glacial environments. We found that concentrations greater than 10−3 M are needed to detect serine and concentrations greater than 10−4 M are needed to detect phenylalanine, with larger concentrations needed for smaller enantiomeric excesses. Salts do not have a significant effect on the optical rotation. Optical rotation of bacterial samples were detected at concentrations >106 cells ml−1. Systematic errors in our polarization detector limited our sensitivity to optical activity changes of ∼0.008°, leading to an inability to distinguish enantiomeric abundances separated by 5%, but tests show that improvements to our laboratory technique can yield a factor of 20 improvement in sensitivity.
Colliding in the Shadows of Giants: Planetesimal Collisions during the Growth and Migration of Gas Giants
Authors: Carter Philip J. , Stewart Sarah T. 
Published: September 2020

Abstract
Giant planet migration is an important phenomenon in the evolution of planetary systems. Recent works have shown that giant planet growth and migration can shape the asteroid belt, but these works have not considered interactions between planetesimals. We have calculated the evolution of planetesimal disks, including planetesimal–planetesimal collisions, during gas giant growth and migration. The numbers, locations, and impact velocities of these collisions depend on the specific growth and migration path. We find that giant planet growth alone has little effect on impact velocities, and most of the planetesimals scattered by growing giants do not undergo collisions. In contrast, we find that giant planet migration induces large numbers of high-velocity collisions between planetesimals. These impacts have sufficient velocities to cause shock-induced vaporization for both water ice and silicate components of planetesimals and to cause disruption of the bodies. New bodies may form from impact debris. Collisional evolution reduces the efficiency of planetesimal implantation into the asteroid belt. A small fraction of the largest planetesimals implanted into the asteroid belt would have been processed via collisions. We identify important consequences of planetesimal collisions that have not been considered in planet accretion models. The prevalence of high-velocity collisions during giant planet migration, and their potential links to the properties of meteorites and the formation of chondrules, makes impact vaporization a critically important phenomenon. The consequences of vaporizing planetesimal constituents require further detailed study. New collision outcome models for impacts within the nebula, and models for new planetesimal formation are needed.

Pages, images, paysages (François Chauveau, Fables choisies mises en vers par M. de La Fontaine )
Authors: Leplatre Olivier 
Published: September 2020

Dans les éditions originales des Fables de La Fontaine, chaque apologue est habituellement précédé de sa gravure. François Chauveau a profité de cet emplacement privilégié qui fait se succéder le lisible au visible pour développer son univers graphique et imaginaire propre. Ainsi, appuyée en particulier sur un renforcement du cadrage qui confère à ses illustrations leur forte autonomie, la lecture de Chauveau procède d’une herméneutique originale qui met à distance, dépasse, oublie même éventuellement le sens moral ou allégorique de la fable. Ses compositions réagissent d’abord à la puissance d’image des récits inventés par La Fontaine et, singulièrement, aux suggestions de paysages qu’ils lui inspirent.
La Mothe Le Vayer, précepteur royal. Relecture d’une trajectoire sociale
Authors: Georges Louis 
Published: September 2020

Parmi les libertins dits érudits, François de La Mothe Le Vayer a souvent passé pour le représentant typique de la duplicité sociale, à la fois libre penseur accusé d’incroyance et précepteur royal fidèlement attaché à la cour. Ce travail cherche à saisir le lien entre la marginalité intellectuelle et la centralité politique de La Mothe Le Vayer en étudiant sa trajectoire comme acteur social. Il approche le préceptorat royal par des sources notariées et monarchiques qui permettent de situer le phénomène libertin dans la société parisienne, de décrire la proactivité des savants dans le système des charges et de comprendre l’activation conjoncturelle d’une relation de patronage construite dans le temps long.
L’expertise au prisme du contrôle du juge
Authors: Chevallier Jacques 
Published: September 2020

Passant par le prisme du contrôle juridictionnel, l’expertise acquiert une portée nouvelle : de stratégie politique, laissée à la discrétion des gouvernants, elle devient une contrainte juridique, sanctionnée par les juges. L’obligation faite aux décideurs politiques de sacrifier à l’exercice et la prise en compte par le juge lui-même des données de l’expertise confèrent désormais à celle-ci une place de choix dans le cycle de production du droit.
Vie et mort de l’État plateforme
Authors: Jeannot Gilles 
Published: September 2020

L’article analyse les représentations et pratiques qui président au projet d’État plateforme, en vogue en France entre 2014 et 2019. Ce projet recouvre plusieurs composantes : le rééquilibrage de l’ open data de la transparence vers l’innovation, le rêve – déçu – de voir des startups spontanément proposer des services administratifs et, surtout, une pratique alternative pour l’informatique autour de microprojets portés par les « startups d’État » et autour de dispositifs légers d’échange de données (API). La mise à l’écart de la notion traduit un retour à des formes plus classiques de standardisation des projets informatiques. « État plateforme » peut être considéré comme une tentative de renouveler l’approche de l’innovation et de la gestion dans l’administration, tentative qui fait écho à l’introduction du « digital » dans les entreprises privées.
Les mobilisations de travailleuses du sexe dans les années 2010 contre la croisade morale abolitionniste
Authors: Devillard Valérie , Le Saulnier Guillaume 
Published: September 2020

Les mobilisations de travailleuses du sexe en faveur de la reconnaissance de leur « métier » ont pour enjeu la représentation des prostituées, de leur condition et de leur activité. Elles s’opposent aux représentations glamourisées ou misérabilistes propagées par les médias mainstream. Elles participent d’un travail de représentation, ici saisi au prisme de photographies de manifestations de rue des années 2010, où s’observe un changement de cadrage interprétatif de la figure de la prostituée.
Poétique de l’engagement sur les plateformes. Figures de la mobilisation et styles de contenus
Authors: Gomez-Mejia Gustavo 
Published: September 2020

Cet article propose une approche poétique des contenus engagés qui animent et font circuler les mobilisations sociales sur les plateformes. Par-delà les ambiguïtés de la notion d’« engagement » en contexte numérique, le but est d’étudier des expressions idéologico-politiques. À partir d’une analyse sémiologique de matériaux français et latino-américains collectés via Twitter et Facebook depuis 2018, l’auteur s’intéresse aux styles de contenus publiés afin de répertorier les principaux procédés créatifs des mobilisations sur les réseaux.
Action convergence of operators and graphs
Authors: Backhausz Ágnes , Szegedy Balázs 
Published: September 2020

AbstractWe present a new approach to graph limit theory that unifies and generalizes the two most well-developed directions, namely dense graph limits (even the more general

$L^p$
limits) and Benjamini–Schramm limits (even in the stronger local-global setting). We illustrate by examples that this new framework provides a rich limit theory with natural limit objects for graphs of intermediate density. Moreover, it provides a limit theory for bounded operators (called P-operators) of the form

$L^\infty (\Omega )\to L^1(\Omega )$
for probability spaces

$\Omega $
. We introduce a metric to compare P-operators (for example, finite matrices) even if they act on different spaces. We prove a compactness result, which implies that, in appropriate norms, limits of uniformly bounded P-operators can again be represented by P-operators. We show that limits of operators, representing graphs, are self-adjoint, positivity-preserving P-operators called graphops. Graphons,

$L^p$
graphons, and graphings (known from graph limit theory) are special examples of graphops. We describe a new point of view on random matrix theory using our operator limit framework.
