Educación, Estado y política en Uruguay: Del imaginario estatista al ascenso de los corporativismos (o la nostalgia de la hegemonía)
Authors: Marrero Adriana , Cafferatta Graciela 
Published: September 2021

En este artículo se intenta mostrar uno de los –tal vez ines­-perados– efectos perversos de la prédica neoliberal de los años ochenta, que consiste no ya en el retiro del Estado como educador, sino en la erosión de su legitimidad para la construcción del espacio público como un lugar donde se diriman los conflictos de intereses, a través de su articulación en la producción de una hegemonía que logre superar la simple puja corporativa. El trabajo examina la coyuntura educativa actual, marcada por un conflicto donde predomina el peso de las corporaciones, en el contexto del ascenso de un gobierno de izquierdas y sobre el tras­-fondo de la trayectoria histórica del Uruguay, caracterizada por el papel clave del Estado no solo para la conducción e impulso de políticas sociales y educativas de avanzada sino mucho antes, para la constitución misma de la nacionalidad «oriental». Luego de un rápido repaso por algunos hitos claves del proceso histórico, el artículo se centra en las políticas educativas aplicadas desde la restauración democrática a mediados de la década de 1980, en la resistencia a la liberalización y a la implementación de líneas de política en el momento actual, para concluir, que la educación uruguaya, detenida y en declive, parece estar naufragando en una lógica de disputa entre un gobierno que ha abandonado su rol propositivo en cuanto a un proyecto educativo inclusivo y hegemónico, y unos sindicatos que no logran llegar al momento en que «la conciencia de que los propios intereses corporativos, en su desarrollo actual y futuro, superan los límites de la corporación» (Gramsci, 1972).

Abstrak
Algoritma kriptografi dapat digunakan untuk mengamankan citra. Salah satu algoritma kriptografi yang dapat digunakan untuk mengenkripsi citra adalah algoritma Serpent. Namun, algoritma Serpent memerlukan proses enkripsi dan dekripsi yang lama. Selain itu, pengenkripsian saja tidaklah cukup karena akan menimbulkan kecurigaan sehingga informasi akan rentan dicuri. Maka diperlukan teknik steganografi seperti metode Integer Wavelet Transform (IWT). Citra rahasia akan dienkripsi terlebih dahulu dengan menggunakan metode Modified Serpent, dimana modifikasi Serpernt mengubah proses transformasi substitusi byte (DES S-box) menjadi list bilangan prima 257 yang memiliki 128 generator untuk digunakan sebagai kunci di setiap putarannya. Pada proses penyisipan dengan metode IWT, perlu ditentukan posisi bit dan piksel pada cover image yang akan disisipkan sebuah pesan. Untuk menentukan posisi tersebut, maka digunakanlah fungsi chaos. Setelah itu, dapat dilakukan proses ekstraksi terhadap citra stego yang dihasilkan pada proses penyisipan untuk memperoleh kembali bit yang tersimpan didalamnya. Kumpulan bit tersebut dapat didekripsi sehingga akan diperoleh kembali citra rahasia semula.

Abstract
Statistical studies of cataloged object properties are central to astrophysics. But one cannot model those objects’ population properties without the sample’s selection function, the quantitative understanding of which objects could have ended up in such a catalog. As didactic introductions to this topic are scarce in the astrophysical literature, we provide one here, addressing the following questions: What is a selection function? On what arguments
q
should it depend? Over what domain must a selection function be defined? What simplifying approximations can be made? And, how is a selection function used in “modeling”? We argue that volume-complete samples, limited by the faintest objects, reflect a highly suboptimal selection function, needlessly reducing the number of bright and usually rare sample members. We illustrate these points by a worked example: github.com/gaia-unlimited/WD-selection-function, deriving the space density of white dwarfs (WDs) in the Galactic neighborhood as a function of their luminosity and color, Φ0(M

Abstract
For the first time, we present the simultaneous detection and characterization of three distinct phases at >105 K in z = 0 absorption using deep Chandra observations toward Mrk 421. The extraordinarily high signal-to-noise ratio (≥60) of the spectra has allowed us to detect a hot phase of the Milky Way circumgalactic medium (CGM) at

107 K coexisting with a warm-hot phase at 1.5 ± 0.1 × 106 K and a warm phase at 3.0 ± 0.4 × 105 K. The warm-hot phase is at the virial temperature of the Galaxy, and the warm phase may have cooled from the warm-hot phase, but the supervirial hot phase remains a mystery. We find that [C/O] in the warm and warm-hot phases, [Mg/O] in the warm-hot phase, and [Ne/O] in the hot phase are supersolar, and the hot and the warm-hot phases are α-enhanced. Nonthermal line broadening is evident in the warm-hot and the hot phases, and it dominates the total line broadening. Our results indicate that the >105 K CGM is a complex ecosystem. It provides insights on the thermal and chemical history of the Milky Way CGM and theories of galaxy evolution.

Abstract
We perform a deep, wide-field imaging survey of nearby galaxies using Hα and broadband filters to investigate the characteristics of star formation in galaxies. Motivated by the finding that star formation rates (SFRs) derived from Hα fluxes in dwarf galaxies are systematically lower than those inferred from far-ultraviolet (FUV) fluxes, we attempt to determine whether the same trend exists in the extended disks of two star-forming galaxies. We perform spatially resolved photometry using grid-shaped apertures to measure the FUV and Hα fluxes of star-forming regions. We also perform spectral energy distribution (SED) fittings using 11 photometric data points (FUV-to-MIR), including data from the literature, to estimate the local properties such as internal attenuation of individual star-forming clumps. Comparing SFRFUV and SFRHα
, which are converted from the Hα and FUV fluxes corrected for the local properties, we find that SFRHα
/SFRFUV tend to decrease as the SFR decreases. We evaluate possible causes of this discrepancy between the two SFRs by restricting parameters in the SED fitting and conclude that deficient Hα fluxes in the extended disks of galaxies are tightly correlated with recent starbursts. The strong and short starburst, which has been rapidly suppressed over the last 10 Myr, seems to induce a significant discrepancy between the SFRHα
and SFRFUV. In addition, the recent bursts in the extended disks of galaxies appear to have occurred azimuth-symmetrically, implying that these were likely triggered by gas accretion or internal processes rather than external perturbation.

Published: September 2021

Background: Oral cancer is one of the most common type of head and neck cancer, with a 5 year survival rate of < 50%. One of the major problems of oral cancer include the late stage of disease at the time of diagnosis. Mirror image biopsy is a new technique that can be used for detection of early changes in the oral mucosa. Aim of the study: To histologically assess the reflect copy biopsy occupied from clinically usual observing mucosa at consistent contralateral anatomical place to the main lesion in patients identified with tongue squamous cell carcinoma to notice any indication of arena alteration in oral mucosa. Materials and methods: Seven patients diagnosed with squamous cell carcinoma of the tongue underwent reflect copy biopsy from clinically usual observing mucosa at consistent contralateral anatomical place to the main lesion. The reflect copy biopsy example were exposed to histopathological check. Results: of the seven patients included, four were male and three were female, with an age range from 45 years to 64 years (median 54.5 years). One of the biopsies revealed severe dysplasia and six-revealed hyperplasia of the epithelium. Conclusion: Mirror image biopsy is a useful tool to detect the early field changes in oral mucosa in order to prevent further progression to oral cancer.

Published: September 2021

Objective: To evaluate and compare the effect of implant supported versus implant retained removable partial denture restoring Kennedy's class I cases on the supporting structures by measuring modified gingival index and probing depth for abutment teeth and implants.
Subjects and Methods: Twelve patients; who had Kennedy class I mandibular partially edentulous ridge extending distal to the first or second premolar, were selected from the outpatient clinic, Prosthodontics Department, Faculty of Dentistry, Minia University. The patients were classified into two equal groups; according to the implant superstructures either dome shaped abutment or ball and socket attachment. Each Patient of both groups had two implants in second molar position (one in each side) and received removable partial denture of the same design. Patients were followed up for one year clinically. Group I: Six patients received RPD supported by dome shaped short abutments. Group II six patients received RPD retained by ball and socket attachments.
Results: Results revealed that, there was no statistically significant difference between the two groups regarding modified gingival index and probing depth around the abutment teeth and implant abutment.
Conclusion: The use of dome shaped abutment or ball and O-ring attachment have the same effect on gingival index and probing depth around natural abutments and implants in Kennedy class I mandibular situations.
Ce que « se laver » signifie : histoire de pratiques et d’expériences
Authors: Richelle Sophie 
Published: September 2021

Tout au long du XX e siècle, les normes d’hygiène d’ablution totale se répandent dans l’ensemble de la société, mais les salles de bains privatives restent durablement l’apanage des plus aisés. Face au manque d’infrastructures disponibles, les bains publics sont une réponse collective à ces nouvelles nécessités. Parmi eux, les bains-douches des charbonnages, qui font l’objet de cet article, constituent un cas d’étude exceptionnel. Dans une histoire sociale des mines encore à faire, ils sont un observatoire inédit de la construction de nos rapports aux corps, à leur hygiène et à leur propreté, ainsi que des différenciations sociales et genrées qui les traversent dans des sociétés ouvrières en voie de transformation au XX e siècle.
La transition numérique des structures œuvrant au service de l’intérêt général peut-elle augmenter leur impact social ?
Authors: Sibieude Thierry , Leclerc Élise 
Published: September 2021

Quelles sont les conditions de la maximisation de l’impact, et notamment sa pérennisation, du mécénat de compétence tech au profit des organisations dont la mission relève directement et prioritairement de la gestion du bien commun au service de l’intérêt général ? Telle est la question de recherche que la Fondation Devoteam a posée à l’ESSEC au moment de la mise en place de son programme #TechFor-People, afin de s’assurer de la pertinence de ce programme pour répondre aux besoins sur le long terme des structures de l’ESS (Économie Sociale et Solidaire) en transformation digitale. Afin de répondre à cette problématique l’ESSEC a réalisé une évaluation d’impact social fondée sur les cadres théoriques de la théorie du changement et de la théorie des parties prenantes, avec l’analyse de besoin, une collecte de données qualitatives ex-ante ainsi qu’une collecte de données quantitative ex-ante et ex-post. L’analyse de ces collectes révèle une dichotomie spécifique aux structures de l’ESS utilisant le programme que nous avons catégorisées en Tech Driven d’une part, ou Tech Powered d’autre part, avec des besoins et des conditions de pérennisation spécifiques en fonction de la catégorie qui leur correspond.

Cold-pressed cactus pear seed oil: Quality and stability
Authors: De Wit M. , Motsamai V.K. , Hugo A. 
Published: September 2021

Cold-pressed seed oil from twelve commercially produced cactus pear cultivars was assessed for oil yield, fatty acid composition, physicochemical properties, quality and stability. Large differences in oil content, fatty acid composition and physicochemical properties (IV, PV, RI, tocopherols, ORAC, % FFA, OSI and induction time) were observed. Oil content ranged between 2.51% and 5.96% (Meyers and American Giant). The important fatty acids detected were C16:0, C18:0, C18:1c9 and C18:2c9,12, with C18:2c9,12, the dominating fatty acid, ranging from 58.56-65.73%, followed by C18:1c9, ranging between 13.18-16.07%, C16:0, which ranged between 10.97 - 15.07% and C18:0, which ranged between 2.62-3.18%. Other fatty acids such as C14:0, C16:1c9, C17:0, C17:1c10, C20:0, C18:3c9,12,15 and C20:3c8,11,14 were detected in small amounts. The quality parameters of the oils were strongly influenced by oil content, fatty acid composition and physicochemical properties. Oil content, PV, % FFA, RI, IV, tocopherols, ORAC and ρ-anisidine value were negatively correlated with OSI. C18:0; C18:1c9; C18:2c9,12; MUFA; PUFA; n-6 and PUFA/SFA were also negatively correlated with OSI. Among all the cultivars, American Giant was identified as the paramount cultivar with good quality traits (oil content and oxidative stability).
Batoko plum (Flacourtia inermis) peel extract attenuates deteriorative oxidation of selected edible oils
Authors: Wedamulla N.E. , Wijesinghe W.A.J.P. 
Published: September 2021

The oxidation of oils has an adverse effect on the organoleptic properties and shelf-life of stored oils. Flacourtia inermis is one of the underutilized fruits grown in Sri Lanka with promising antioxidant properties. F. inermis peel extract (FIPE) was used to retard rancidity in edible oils. The efficacy of added FIPE (500, 1000, 2000 ppm) on sunflower oil (SO) and virgin coconut oil (VCO) was monitored at 3-day intervals at 65 ± 5 °C against a positive control (α-tocopherol at 500 ppm level) using Free Fatty Acid (FFA) and Peroxide Value (PV). Oils without FIPE were used as the control. Antioxidant efficacy (IC50) and Total Phenol Content (TPC) of FIPE were determined by DPPH assay and the Folin-Ciocalteu method. Fourier transform infrared spectroscopy was used to monitor the oxidative stability. The IC50 value and TPC of FIPE were 227.14 ± 4.12 µg·mL-1 and 4.87 ± 0.01 mg GAE/g extract, respectively. After 21 days, VCO (control) sample exhibited significantly (p < 0.05) higher FFA and PV than the treatments. FIPE exhibited comparable results with α-tocopherol. Conclusively, FIPE had strong antioxidant properties and thus, could be used as an alternative to α-tocopherol to improve the oxidative stability of virgin coconut oil and sunflower oil. However, only minor differences in the FTIR spectra were detected in treated and untreated virgin coconut and sunflower oil samples after 21 days storage at 65 ± 5 °C.

Authors: Yeung Meredith T 
Published: September 2021

Aims:
To investigate the acceptability and feasibility of a four-station multiple mini-interview (MMI) model for admission selection into the four allied health undergraduate programs in Singapore.

Methods:
From 2015 to 2017, applicants to the four allied health undergraduate programs (physical therapy, occupational therapy, diagnostic radiography, and radiation therapy) at a university in Singapore underwent a four-station MMI. In 2017, interviewers of the MMI were polled using a 7-point Likert scale survey. Descriptive statistics were performed to analyze the quantitative portion of the survey, while content analysis and thematic description were applied to the qualitative data.

Results:
Data was collected from 79 interviewers. The majority agreed that the MMI was a fair process for applicants (83.5%), a good way of assessing interest and potential to become healthcare professionals (78.5%), and tested more aspects of the applicants than the traditional interviews (72%). They concluded that the MMI format was structured, objective, rigorous, unbiased, and assessed a valid range of competencies (67%).

Conclusion:
This study assessed and established the acceptability and feasibility of the MMI for undergraduate admissions to the allied health programs in Singapore.

COVID Bedfellows
Authors: Malone Erin D , Brown Abby L , Spence Susan J 
Published: September 2021

Background:
Prior to the fall of 2020, clinical skills and anatomy were considered separate courses with minimal overlap other than being offered to the same cohort of students. We had included clinical skills practice in anatomy labs on an intermittent and variable basis. Many of the skills were included only if time and faculty or staff availability permitted. The coronavirus disease 2019 (COVID-19) pandemic made us think differently, particularly as the anatomy space was one of our largest rooms.

Methods:
Anatomy and clinical skills shared space and content during the 2020–2021 school year in an effort to meet physical distancing and other biosafety requirements required by the state and University.

Results:
Students were maintained in a single space and were engaged for a longer period of time, making their commute and biosafety steps worthwhile while simultaneously opening up other spaces for distanced teaching needs. The goal of one skill/day for motor skill learning was maintained despite a challenging laboratory teaching schedule. Certified veterinary technicians taught both the anatomy and the skills portion, showcasing the value of their training and freeing faculty for other responsibilities.

Conclusion:
This teaching and learning combination led to an enhanced understanding of procedure-related anatomy; direct anatomy application to veterinary work; opportunities for recall, transfer, and supervised practice; and optimized staff and space utilization.
