Ciudadanías del saber constructo dinámico emergente complejo Acercamiento del concepto ciudadanía desde la antigüedad hasta nuestros diasitulo del capitulo
Authors: Carvajal Arias Andres 
Published: March 2023

El concepto ciudadanías se ha configurado como una categoría de reconocimiento que aborda un universo conceptual el cual a través de los tiempos ha comportado distintas modificaciones de nivel contextual a pesar de estos cambios su raíz se encuentra predeterminada bajo una connotación de orden determinista suscrita en un paradigma de orden occidental que imposibilita una acertada ramificación de reconocimiento y de articulación sobre otras posibles génesis de transfiguración sobre esta categoría nominal.
En orden de dar no solo una revisión conceptual sobre esta categoría sino de tejer nuevas posibilidades de comprensión y actuación reticular sobre esta categoría (ciudadanías planetarias) en apoyo de las (reformas del pensamiento) desarrollo macro-conceptual de Edgar Morín y el estudio de las nuevas ciencias (ciencias de la vida) se realiza esta investigación con el fin de potenciar nuevos universos conceptuales suscritos a sociedades complejas que no sinteticen sino amplíen nuevas configuraciones sistémicas de multiplicidad en donde el reconocimiento se da de orden modular.
En consonancia con el pensamiento de la complejidad y la constitución de nuevas epistemes de orden científico social (epistemologías de la complejidad y epistemologías del sur) en donde se traslucida nuevos horizontes de comprensión con el objetivo de abordar y aplicar la lógica del tercero incluido sobre los fenómenos de estudio surge esta investigación.
Investigación que busca no dar respuestas de certitud sino constituir nuevos espacios de narrativa en donde el saber y el conocimiento científico interactúan de orden inter-retro-activo.
The Celestial Reference Frame at K Band: Imaging. I. The First 28 Epochs

Published: March 2023

Abstract
We present K-band (24 GHz) images of 731 compact extragalactic radio sources with submilliarcsecond resolution, based on radio interferometric observations made with the Very Long Baseline Array of 10 telescopes during 29 day long sessions spanning from 2015 to 2018 and recorded at 2048 Mbps. Many of these sources are imaged with submilliarcsecond resolution for the first time at frequencies above X band (8 GHz). From each of the K-band images, we derive the following source properties: peak brightness, core and total flux density, the ratio of peak and core to total flux (compactness measure), radial source extent, structure index, source size, and jet direction. The vast majority of sources are imaged at multiple epochs, providing insights into their temporal behavior. The use of K band was motivated by the fact that the sources are generally intrinsically more compact at higher frequencies, as well as by the factor of 3 improvement in interferometer resolution relative to the historically standard S/X band (2.3/8.4 GHz) used for a large amount of reference frame and calibrator work. Lastly, as most of the sources imaged here are in the K-band component of the third International Celestial Reference Frame, these images serve to characterize the objects used in that International Astronomical Union standard.

Abstract
We report the results of a search for long-period (100 < P < 600 days) periodic variability in the SDSS Stripe 82 standards catalog. The SDSS coverage of Stripe 82 enables such a search because there are on average 20 observations per band in ugriz bands for about one million sources, collected over about 6 yr, with a faint limit of r ∼ 22 mag and precisely calibrated 1%–2% photometry. We calculated the periods of variable source candidates in this sample using the Lomb–Scargle periodogram and considered the three highest periodogram peaks in each of the gri filters as relevant. Only those sources with gri periods consistent within 0.1% were later studied. We use the Kuiper statistic to ensure uniform distribution of data points in phased light curves. We present five sources with the spectra consistent with quasar spectra and plausible periodic variability. This SDSS-based search bodes well for future sensitive large-area surveys, such as the Rubin Observatory Legacy Survey of Space and Time, which, due to its larger sky coverage (about a factor of 60) and improved sensitivity (∼2 mag), will be more powerful for finding such sources.
Radius-dependent Spin Transition of Dark Matter Halos
Authors: Moon Jun-Sung , Lee Jounghun 
Published: March 2023

Abstract
A numerical detection of the radius-dependent spin transition of dark matter halos is reported. Analyzing the data from the IllustrisTNG simulations, we measure the halo spin vectors at several inner radii within the virial boundaries and investigate their orientations in the principal frames of the tidal and velocity shear fields, called the Tweb and Vweb, respectively. The halo spin vectors in the high-mass section exhibit a transition from the Tweb intermediate to major principal axes as they are measured at more inner radii, which holds for both the dark matter and baryonic components. The radius threshold at which the transition occurs depends on the smoothing scale, R

f
, becoming larger as R

f
decreases. For the case of the Vweb, the occurrence of the radius-dependent spin transition is witnessed only when R

f
≥ 1 h
−1 Mpc. Repeating the same analysis but with the vorticity vectors, we reveal a critical difference from the spins. The vorticity vectors are always perpendicular to the Tweb (Vweb) major principal axes, regardless of R

f
, which indicates that the halo inner spins are not strongly affected by the generation of vorticity. It is also shown that the halo spins, as well as the Tweb (Vweb) principal axes, have more directional coherence over a wide range of radial distances in the regions where the vorticity vectors have higher magnitudes. The physical interpretations and implications of our results are discussed.

Abstract
The Dark Energy Spectroscopic Instrument (DESI) survey will measure large-scale structures using quasars as direct tracers of dark matter in the redshift range 0.9 < z < 2.1 and using Lyα forests in quasar spectra at z > 2.1. We present several methods to select candidate quasars for DESI, using input photometric imaging in three optical bands (g, r, z) from the DESI Legacy Imaging Surveys and two infrared bands (W1, W2) from the Wide-field Infrared Survey Explorer. These methods were extensively tested during the Survey Validation of DESI. In this paper, we report on the results obtained with the different methods and present the selection we optimized for the DESI main survey. The final quasar target selection is based on a random forest algorithm and selects quasars in the magnitude range of 16.5 < r < 23. Visual selection of ultra-deep observations indicates that the main selection consists of 71% quasars, 16% galaxies, 6% stars, and 7% inconclusive spectra. Using the spectra based on this selection, we build an automated quasar catalog that achieves a fraction of true QSOs higher than 99% for a nominal effective exposure time of ∼1000 s. With a 310 deg−2 target density, the main selection allows DESI to select more than 200 deg−2 quasars (including 60 deg−2 quasars with z > 2.1), exceeding the project requirements by 20%. The redshift distribution of the selected quasars is in excellent agreement with quasar luminosity function predictions.

Abstract
We present the first estimation of the energy cascade rate in Jupiter’s magnetosheath (MS). We use in situ observations from the Jovian Auroral Distributions Experiment and the magnetometer investigation instruments on board the Juno spacecraft, in concert with two recent compressible models, to investigate the cascade rate in the magnetohydrodynamic (MHD) scales. While a high level of compressible density fluctuations is observed in the Jovian MS, a constant energy flux exists in the MHD inertial range. The compressible isothermal and polytropic energy cascade rates increase in the MHD range when density fluctuations are present. We find that the energy cascade rate in Jupiter’s magnetosheath is at least 2 orders of magnitude (100 times) smaller than the corresponding typical value in the Earth’s magnetosheath.

Abstract
We report the second extragalactic pulsar wind nebula (PWN) to be detected in the megaelectronvolt–gigaelectronvolt band by the Fermi-LAT, located within the Large Magellanic Cloud. The only other known PWN to emit in the Fermi band outside of the Milky Way is N157B, which lies to the west of the newly detected gamma-ray emission at an angular distance of 4°. Faint, pointlike gamma-ray emission is discovered at the location of the composite supernova remnant (SNR) B0453-685 with a ∼4σ significance with energies ranging from 300 MeV–2 TeV. We present the Fermi-LAT data analysis of the new gamma-ray source, coupled with a detailed multiwavelength investigation to understand the nature of the observed emission. Combining the observed characteristics of the SNR and the physical implications from broadband modeling, we argue it is unlikely that the SNR is responsible for the gamma-ray emission. While the gamma-ray emission is too faint for a pulsation search, we try to distinguish between any pulsar and PWN component of SNR B0453-685 that could be responsible for the observed gamma-ray emission using semi-analytic models. We determine the most likely scenario is that the old PWN (τ ∼ 14,000 yr) within B0453-685 has been impacted by the return of the SNR reverse shock with a possible substantial pulsar component below 5 GeV.

Abstract
We present low-resolution optical spectra and classifications of 92 blue objects with mid-infrared excesses in the Large Magellanic Cloud. The majority of these objects were selected with the criteria of U − B < 0 and V < 17 from the potential young stellar object (YSO) candidates in Gruendl & Chu (GC09), which were identified based on Spitzer Infrared Array Camera and Multiband Imaging Photometer for Spitzer observations in conjunction with optical photometry from the Magellanic Clouds Photometric Survey. Many of the sample objects have ambiguous classifications. We examined the properties of these 92 objects using low-resolution optical spectra obtained with the SOAR 4.1 m Telescope at Cerro Pachon and the Blanco 4 m Telescope at Cerro Tololo Inter-American Observatory, supplemented by available photometric and imaging observations. We estimated the spectral types, temperatures, and luminosities of these objects from the optical to near-IR spectral energy distributions based on the photometric data, and further examined stellar absorption line features in the optical spectra to verify the spectral types. The interstellar/circumstellar environments, assessed from nebular line imaging observations and nebular lines detected in the stellar spectra, further helped constrain the nature of stars. Among these 92 objects, we confirm 42 stars as YSOs, and the remaining 50 objects as protoplanetary nebulae, post-AGB/RGB stars, blue evolved massive stars, stars with dust in vicinity, or uncertain classifications. Our results show that the photometric criteria in GC09 are generally effective in the initial selection of YSO candidates, and the low-resolution spectroscopy combined with environment assessment can be useful to better constrain the classifications and ameliorate most ambiguities.

V prispevku smo preučili, kako problematiko mladih dojemajo mladi. Izvedli smo anketo, ki smo jo nadgradili s ciljno usmerjenimi intervjuji. Mladi kot najbolj perečo opredeljujejo stanovanjsko problematiko, sledijo druženje, medosebni odnosi in vključevanje v družbo, problematika delovnih mest pa pri ocenjevanju kakovosti življenja v občini bivanja ni v ospredju, ji pa večji poudarek namenjajo pri predlogih rešitev. Podrobnejša analiza pokaže na razlike med posameznimi skupinami mladih: (1) med živečimi na podeželju in v mestu, (2) med dijaki in študenti ter delovno aktivnimi ter (3) med tistimi z rešenim stanovanjskim problemom in tistimi, ki stanovanjskega problema še nimajo rešenega. V primerjavi s predhodnimi študijami presenečajo zlasti problem medsebojnega druženja, sobivanja s starejšimi in vključevanja v družbo. //
Main problems of Slovenian youth: A study focusing on life quality, housing, and jobs
This study investigates how youth problems are perceived by young people themselves. We conducted a survey supplemented by targeted interviews. Young people mention housing as the most pressing problem for them, followed by socialization, interpersonal relationships, and integration into society. In contrast, jobs do not feature prominently in their evaluation of the quality of life in their municipality of residence; instead, they place more emphasis on finding a solution. A more detailed analysis shows differences between different groups of young people: (1) between those living in the countryside and those living in the city, (2) between students and those that are employed, and (3) between those that have found their own place to live and those still looking for a place. Compared to previous studies, the problems of socializing, intergenerational cooperation, and integrating into society are particularly surprising.
Prilaščanje pokrajine Sečoveljskih solin: naravna in kulturna dediščina
Authors: Topole Maja , Pipan Primož 
Published: March 2023

Prispevek preučuje neustrezno upravljanje solinske pokrajine kot dediščine. Predstavi Sečoveljske soline kot del kulturne pokrajine, ki se je verjetno začela razvijati že v antiki, pisni viri pa obstajajo od 13. stoletja dalje. Poudarek je na območju Fontanigge, Muzeju solinarstva, dediščinjenju srednjeveškega solinarstva, komercializaciji Sečoveljskih solin, dediščinjenju narave in biodiverzitete ter s tem povezani problematiki upravljanja srednjeveške solinarske dediščine na območju Fontanigge. Prepad med dediščinjenjem narave in dediščinjenjem kulture korenini tudi v strokovnem in uradnem poimenovanju, izhajajočem iz zakonodaje. Ključna ugotovitev je nesmiselnost umetnega ločevanja dediščine na naravno in kulturno, še posebej v primeru kulturne pokrajine, kjer bi morali biti zastopani tudi običaji in tradicije prebivalcev.
The appropriation of the Sečovlje saltpans landscape: natural and cultural heritage
The paper examines the inadequate management of the landscape as a cultural heritage. It presents the Sečovlje Saltpans and saltworks as part of the old cultural landscape, Fontanigge with the Museum of Salt Making and the heritage of medieval salt making, the commercialization of the Sečovlje Saltpans, the heritagization of nature and biodiversity, and the related conflict in the management of the medieval salt making heritage in the Fontanigge area. The gap between the heritagization of nature and heritagization of culture has its roots also in the professional and official naming resulting from the legislation. The main finding is the absurdity of the artificial Cartesian separation of heritage into nature and culture, especially in the case of the cultural landscape, where the customs and traditions of the inhabitants should also be represented.
Lozère, « pays des sources »
Authors: Fock-Chow-Tho Cécile 
Published: March 2023

Département de moyenne montagne, la Lozère est souvent comparée à un château d’eau alimentant trois bassins versants. L’eau est partout présente, abondante sur la Margeride et l’Aubrac, souterraine sur les causses. Sur les Cévennes s’accumulent des masses de pluies, violentes au printemps et à l’automne, renflouant régulièrement sources et cours d’eau malgré la chaleur méditerranéenne. L’eau est une richesse qu’il faut préserver mais aussi dompter. Le patrimoine bâti en lien avec cet élément est donc, de la même façon, omniprésent. S’il est souvent difficile à dater de manière absolue, il participe à la vie quotidienne des habitants, sans cesse entretenu, voire reconstruit. Le XIXe siècle marque un usage de l’eau démultiplié, avec l’ère industrielle. Le XXe siècle, avec l’utilisation intensive du béton, a modifié un certain nombre de paysages en créant digues et barrages.Cet article est volontairement thématique et non chronologique en raison des difficultés de datation de la plupart des ouvrages vernaculaires. Deux thèmes principaux y sont développés : la gestion de l’eau et l’eau comme vecteur économique. Sa gestion efficiente est essentielle et l’été qui vient de s’achever montre que le développement anarchique nuit à la ressource. La Lozère conserve encore beaucoup d’installations, certaines aujourd’hui inutilisées, mais d’autres encore en usage. Cet article dresse donc un panorama des plus intéressantes d’entre elles.

Published: March 2023

Depuis 2011, des travaux universitaires et des programmes de recherche sont menés en région Occitanie entre les Pyrénées centrales et la rivière Tarn, donnant lieu en 2021 à la création du projet collectif de recherche (PCR). Ce collectif interdisciplinaire, universitaire et associatif, étudie les relations Homme/Milieu sur le bassin versant de la Garonne amont, des Pyrénées centrales à Toulouse, autour de l’axe fluvial Garonne. Un aperçu des travaux du PCR est présenté autour de la zone d’atelier Boussens-Cazères qui permet d’apporter les premiers éléments de compréhension entre l’occupation et l’exploitation anthropique de l’espace fluvial avec les réponses et réajustements environnementaux, entre le XVe et le XIXe siècle.
PHENOTYPIC AND MOLECULAR DETECTION OF BIOFILM FORMATION IN METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS ISOLATED FROM DIFFERENT CLINICAL SOURCE IN ERBIL CITY
Authors: Ahmad Pishtiwan 
Published: March 2023

Abstract.
Background: Staphylococcus aureus is an important causative pathogen. The production of biofilms is an important factor and makes these bacteria resistant to antimicrobial therapy.
Objectives: the current study aimed to assess the prevalence of resistance to antibacterial agents and to evaluate the phenotypic and genotypic characterization of biofilm formation among S. aureus strains.
Methods: In this study, 50 isolates of Methicillin-resistant S. aureus (MRSA) and Methicillin-Susceptible S. aureus (MSSA) were included. S. aureus was identified by molecular and conventional methods. Antimicrobial resistance was tested with a disc diffusion method. The biofilm formation was performed through Microtiter plate method. Strains were subjected to PCR to determine the presence of nuc, mecA, icaA, icaB, icaC, and icaD gene.
Results: Of the total 50 S. aureus isolates, 32(64%) and 18(36%) were MRSA and MSSA respectively. A large number of MRSA and MSSA isolates showed resistance to Penicillin and Azithromycin and a lower number of MRSA and MSSA isolates showed resistance to Amikacin Gentamicin and none of the isolates was resistant to Vancomycin. The MRSA strains had significantly higher resistance against antibiotics than MSSA strains (P = 0.0154). All isolates (MRSA and MSSA) were able to produce biofilm with levels ranging from strong (31.25 %), (16.6%) to moderate (53.12%), (50%) to weak (15.6 %), (33.3% %) respectively. The MRSA strains had significantly higher ability of biofilm formation than MSSA strains (P = 0.0079). The biofilm encoding genes were detected among isolates with different frequencies. The majority of S. aureus isolates 42 (84%), were found to be positive for the icaA. The prevalence rates of the icaB, icaC, and icaD genes were found to be 37 (74%), 40 (80%) and 41 (82%) respectively.
Conclusions: The prevalence of biofilm encoding genes, which are associated with multidrug resistance in S. aureus strains, is high. Therefore, identification of epidemiology, molecular characteristics, and biofilm management of S. aureus infection would be helpful.
