Aleijadinho, the 'Baroque Hero,' and Brazilian Nationality
Authors: De Grammont Guiomar 
Published: July 2024

ABSTRACT: This article discusses the various discourses that established Antonio Francisco Lisboa, known as “Aleijadinho,” as a cultural hero who anticipated a supposed “Brazilian cultural identity.” This myth, constructed as a biographical fiction in the nineteenth century, was later re-appropriated as historical evidence in a number of programs in the history of thought regarding the arts and letters in Brazil. In the nineteenth and twentieth centuries, these programs proposed their own interpretations of the works attributed to Aleijadinho, mobilizing notions of race, environment, psychology, art and politics that were not documented at the time of the works’ creation. This article is concerned with the material, institutional and rhetorical conditionings of artistic production in the eighteenth century, in order to provide evidence for the argument that the term “Baroque,” and the psychologizing and expressive categories associated with it in many of these discourses, are in fact external to the actual effective practices of Luso-Brazilian artists at that time.
KEYWORDS: Aleijadinho; Baroque; History of Brazilian Art; Cultural Hero; Nationalism
RESUMO: Este texto faz referência aos discursos de vários gêneros que, desde o século XIX, produziram Antônio Francisco Lisboa, “o Aleijadinho”, como um herói cultural ante-cipador da suposta “identidade cultural brasileira”. O mito assim construído como ficção biográfica no século XIX foi reapropriado como evidência histórica, posteriormente, em diversos programas da história do pensamento sobre artes e letras no Brasil. Nos séculos XIX e XX, propuseram interpretações das obras atribuídas ao Aleijadinho, mobilizando noções raciais, ambientais, psicológicas, artísticas e políticas não documentadas no tempo do artífice. O texto trata de condicionamentos materiais, institucionais e retóricos da produção artística no século XVIII, para evidenciar que o termo “barroco” e as categorias psicologistas e expressivas a ele associadas em muitos desses discursos são exteriores às práticas efetivas dos artífices luso-brasileiros desse tempo.

Published: July 2024

El empleo de las redes sociales para emitir comunicados de prensa ha supuesto un cambio en las rutinas periodísticas. Debido a ello, las deportistas han comenzado a utilizarlas como medios a través de los que difundir sus propias informaciones, lo que ha provocado que se conviertan en fuentes directas de información. El objetivo de esta investigación es analizar la conversación social ante el comunicado de denuncia que publicó la jugadora Jennifer Hermoso en la red social X tras el beso no consentido del expresidente de la Real Federación Española de Fútbol, Luis Rubiales, en la final del Mundial de Fútbol Femenino de 2023. Se estudió si las respuestas al comunicado de Hermoso fueron mayoritariamente positivas o negativas, así como los aspectos puestos en valor por los usuarios y usuarias en su respuesta a la publicación de la jugadora. Para la extracción y recopilación de las respuestas se ha empleado la herramienta Twitter Replies Exporter y para el estudio de estas, se ha utilizado el análisis de contenido. Los resultados muestran que la respuesta a la publicación de la deportista ha sido mayoritariamente positiva, pese a que los mensajes negativos han sido, fundamentalmente, insultos con grados de negatividad elevados. El análisis efectuado muestra que el movimiento #SeAcabó, iniciado espontáneamente en X como reacción a la agresión de Rubiales, implica un cambio en el discurso social, ya que manifiesta una respuesta de apoyo generalizada ante la denuncia pública de discriminación y violencia en el deporte femenino.

Authors: Kim Jong-Kil , Kim Do-Yeon , Oh Jong-Sung , Ko Dong-ill , Lee Kwang-Bok 
Published: July 2024

Background: Surgical treatment for Freiberg disease (also known as avascular necrosis of the metatarsal head) has not been completely defined. This retrospective study evaluated short-term outcomes after arthroscopic treatment of Freiberg disease.
Methods: From 2015 to 2019, 13 patients (15 feet) diagnosed as having Freiberg disease were enrolled for arthroscopic surgery. Feet were divided based on the Smillie classification system (two with stage I, eight with stage II, three with stage III, one with stage IV, and one with stage V). Arthroscopic interventions, including synovectomy, debridement, chondroplasty, microfracture, and loose body removal, were performed without considering the Smillie classification stage. Radiologic outcomes were evaluated by radiography (preoperatively and 3, 6, and 12 months postoperatively) and magnetic resonance imaging (preoperatively and 12 months postoperatively). Clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) lesser metatarsophalangeal (MTP)–interphalangeal score and the visual analog scale (VAS) score. The MTP joint range of motion was measured using a goniometer preoperatively and postoperatively.
Results: Radiologic studies showed no evidence of osteonecrosis progression in postoperative 12-month radiographs of any patients. Postoperative 12-month magnetic resonance images showed reduction of bone marrow edema, irregularity of subchondral bone, and cartilage defects in all patients. Significant improvements in AOFAS and VAS scores occurred at all postoperative time points compared with preoperative scores (P = .001). The MTP joint range of motion also showed improvement at last follow-up (P = .001).
Conclusions: Arthroscopic surgery for Freiberg disease showed excellent clinical outcomes, MTP joint range of motion, and short-term outcomes regardless of stage (Smillie classification) in radiologic evaluation.

Published: July 2024

Background: Nail excisions are indicated for onychocryptosis and nail spicules. They are technically demanding and require a refined skill set. We aimed to characterize practice patterns of US providers performing nail excisions.
Methods: We conducted a retrospective analysis of Medicare provider use and payment data, part D, for all claims of partial or complete nail/nail matrix excision with/without nail plate removal/destruction (current procedural terminology code 11750). High performers were defined as providers performing annual nail excisions 2 standard deviations above the mean. We analyzed demographic risk factors for nail excision high performers, including practice location, years of experience, household median income, practice type, and provider gender. Statistical analysis was conducted in SAS v9.4, with values of P < .05 considered statistically significant.
Results: Providers (n = 32,279) and high performers (n = 942) performed mean 34.7 and 173 nail excisions annually. Unsurprisingly, podiatrists constituted 99.7% of all nail excision performers. Providers in the South versus Midwest and Northeast were more often nail excision high performers (odds ratio [OR], 1.95; P < .0001, and OR, 1.46; P < .0001). Solo versus group practitioners were more likely, respectively, to be nail excision high performers (OR, 2.15; P < .0001). With linear regression analysis, for every 10-year increase in years of provider experience, there was an increase of 1.2 nail excisions annually per provider (P < .0001). For every $100,000 increase in household median income of practice location, there was a decrease of 9.9 nail excisions annually per provider.
Conclusions: Southern podiatrists, podiatrists with more years of experience, solo practitioners, and those practicing in regions with lower household median incomes were more likely to perform higher numbers of nail excisions. Identifying performance trends among podiatrists can help podiatrists understand how their performance of nail excisions compares to other podiatrists across the country.

Published: July 2024

Background: Foot pain is a common presentation, and management is generally geared toward pressure offloading. Although several pressure offloading devices exist on the market, the search for the optimal device is ongoing.
Methods: We recently developed PopSole, an inexpensive, simple, balanced offloading insole focused on reducing targeted foot pain. We conducted a prospective validation study of patients with foot pain lasting longer than 6 months to assess the durability and efficacy of the device with follow-up scheduled at 2 weeks, 4 weeks, 2 months, and 3 months. Patient-reported outcomes were collected using multiple validated surveys. Fifteen patients were enrolled in this study.
Results: At 4 weeks, pain, function, and quality of life across all surveys showed statistically significant improvement. For the 6 patients with long-term outcomes (3 months), patients reported improvement in their pain, function, and quality of life across all surveys, which were significant in the Mayo survey (P = .018), the Manchester Foot Pain and Disability Index (P = .014), the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale (P = .032), the Foot and Ankle Ability Measure activities of daily living (P = .009), and the Pittsburgh foot survey (P = .01); the Foot and Ankle Ability Measure sports approached statistical significance (P = .058).
Conclusions: The PopSole is a durable and effective device to relieve foot pain, improve function, and improve quality of life for up to 3 months of use.
IoT-based Facial Recognition Door Lock with Push Button Combination
Authors: Syarifuddin  , Syam Husain , Syafar Faisal 
Published: July 2024

A common issue in many households is the management of door keys, which can often be lost, damaged, or forgotten. This problem can be particularly frustrating when family members arrive home to find they cannot enter their residence. One potential solution to this problem is the implementation of a facial recognition system, which can be used by multiple family members to gain access to their home. The proposed system utilizes an intelligent minicomputer with a dual function, serving as both a Central Processing Unit (CPU) and a monitor screen display connected via an HDMI to VGA adapter. Additionally, the system incorporates a RealVNC Viewer (Virtual Network Computer) as a remote desktop application, accessible via a laptop or Android device. The primary aim of this research is to develop a facial recognition system that can unlock a house door by detecting and matching the user's face with stored data. The minicomputer, acting as a microcontroller, captures the user's face through a camera and compares it with the photo database. If a match is found, the system grants access and displays information on the Android device, indicating whether the user is known or unknown. This study employs a Research and Development (R&D) approach to enhance the effectiveness and security of home control systems using an internet network and Android devices. The system successfully detects facial objects within the camera's range, with the detection point area turning left, right, or focusing towards the front of the rectangular frame. The buzzer indicator sounds when the door lock is open. The system has been tested with multiple users, with local detection distance and over a well-validated network.

Published: March 2014

AbstractThe Visible Infrared Imaging Radiometer Suite (VIIRS) is the next‐generation polar‐orbiting operational environmental sensor with a capability for global aerosol observations. The VIIRS aerosol Environmental Data Record (EDR) is expected to continue the decade‐long successful multispectral aerosol retrieval from the NASA's Earth Observing System Moderate Resolution Imaging Spectroradiometer (MODIS) for scientific research and applications. Since the launch of the Suomi National Polar‐orbiting Partnership (S‐NPP), the VIIRS aerosol calibration/validation team has been continuously monitoring, evaluating, and improving the performance of VIIRS aerosol retrievals. In this study, the VIIRS aerosol optical thickness (AOT) at 550 nm EDR at current Provisional maturity level is evaluated by comparing it with MODIS retrievals and measurements from the Aerosol Robotic Network (AERONET) and the Maritime Aerosol Network (MAN). The VIIRS global mean AOT at 550 nm differs from that of MODIS by approximately −0.01 over ocean and 0.03 over land (0.00 and −0.01 for the collocated retrievals) but shows larger regional biases. Global validation with AERONET and with MAN measurements shows biases of 0.01 over ocean and −0.01 over land, with about 64% and 71% of retrievals falling within the expected uncertainty range established by MODIS over ocean (±(0.03 + 0.05AOT)) and over land (±(0.05 + 0.15AOT)), respectively. The VIIRS retrievals over land exhibit slight overestimation over vegetated surfaces and underestimation over soil‐dominated surfaces. These results show that the VIIRS AOT at 550 nm product provides a solid global data set for quantitative scientific investigations and environmental monitoring.

AbstractAn efficient synthetic strategy for the unique class of pyrazolo[1,2‐a]cinnolines was developed through a rhodium‐catalyzed oxidative coupling of N‐aryl‐1H‐pyrazol‐5(4H)‐ones with internal alkynes. This protocol features use of the pyrazolone function in the substrate as an intrinsic directing group, hexafluoroisopropyl alcohol (HFIP) as the solvent, and mild reaction conditions as well as a wide substrate scope.magnified image
Molekulare CuII‐O‐CuII‐Komplexe: Stille Wasser sind tief
Authors: Haack Peter , Limberg Christian 
Published: March 2014

AbstractDie Forschung zur O2‐Aktivierung an ligierten CuI‐Ionen wird durch ihre biologische Relevanz und die Suche nach effizienten Oxidationskatalysatoren getrieben. Ein in diesem Zusammenhang selten beobachteter Reaktionspfad ist die ungewöhnliche Bildung von CuII‐O‐CuII‐Einheiten: Ein einzelner, zwischen zwei CuII‐Ionen gebundener Oxoligand erfährt eine beträchtliche Elektronendichte, die Cu2O‐Komplexe sehr reaktiv und somit nur schwer zugänglich macht. Daher – und auch wegen der scheinbar fehlenden biologischen Bedeutung – wurden bisher nur wenige solche Verbindungen synthetisiert und charakterisiert. Kürzlich jedoch wurden CuII‐O‐CuII‐Einheiten als aktive Spezies für die selektive Oxidation von Methan zu Methanol sowohl auf der Oberfläche eines kupferhaltigen Zeoliths als auch im aktiven Zentrum der Methanmomooxygenase diskutiert. Dieser Kurzaufsatz soll einen Überblick über den aktuellen Wissensstand bezüglich niedermolekularer Systeme bieten, mit einem Fokus auf ihren spektroskopischen Eigenschaften und Reaktivitäten.
Synthesis and characterization of high‐molecular weight aliphatic polyesters from monomers derived from renewable resources
Authors: Kong Xiaohua , Qi Hong , Curtis Jonathan M. 
Published: March 2014

ABSTRACTA series of high‐molecular weight aliphatic polyesters have been synthesized, at temperatures of < 200°C, through a polycondensation reaction between 1,4‐butanediol and three diacids of different chain length (succinic acid, azelaic acid, and sebacic acid). All the polyesters obtained have a bio‐based content of 100% and number average molecular weight in the range of 28,000–116,000 Da. These average molecular weights are about 5–10 times higher than those of most reported aliphatic polyesters synthesized through similar reaction routes but at temperatures > 230°C. The over‐heating phenomenon, i.e., the observation of thermal degradation behavior of these polyesters at 230°C is reported. The crystallization behavior, mechanical properties, and enzymatic hydrolysis rate of the polyesters obtained are characterized. Poly(butylene succinate) (PBSu) shows the highest crystallinity and melting temperature, but the lowest thermal stability and slowest potential rate of enzymatic biodegradation rate compared with poly(butylene azelate) and poly(butylene sebacate). © 2014 Wiley Periodicals, Inc.

Structural characterization of hydrophilic polymer blends/montmorillonite clay nanocomposites
Authors: Sengwa Ram Jeewan , Choudhary Shobhna 
Published: March 2014

ABSTRACTThe nanocomposite films comprising polymer blends of poly(vinyl alcohol) (PVA), poly(vinyl pyrrolidone) (PVP), poly(ethylene oxide) (PEO), and poly(ethylene glycol) (PEG) with montmorillonite (MMT) clay as nanofiller were prepared by aqueous solution casting method. The X‐ray diffraction studies of the PVA–x wt % MMT, (PVA–PVP)–x wt % MMT, (PVA–PEO)–x wt % MMT and (PVA–PEG)–x wt % MMT nanocomposites containing MMT concentrations x = 1, 2, 3, 5 and 10 wt % of the polymer weight were carried out in the angular range (2θ) of 3.8–30°. The values of MMT basal spacing d001, expansion of clay gallery width Wcg, d‐spacing of polymer spherulite, crystallite size L and diffraction peak intensity I were determined for these nanocomposites. The values of structural parameters reveal that the linear chain PEO and PEG in the PVA blend based nanocomposites promote the amount of MMT intercalated structures, and these structures are found relatively higher for the (PVA–PEO)–x wt % MMT nanocomposites. It is observed that the presence of bulky ester‐side group in PVP backbone restricts its intercalation, whereas the adsorption behavior of PVP on the MMT nanosheets mainly results the MMT exfoliated structures in the (PVA–PVP)–x wt % MMT nanocomposites. The crystallinities of the PEO and PEG were found low due to their blending with PVA, which further decreased anomalously with the increase of MMT concentration in the nanocomposites. The decrease of polymer crystalline phase of these materials confirmed their suitability in preparation of novel solid polymer nanocomposite electrolytes. © 2014 Wiley Periodicals, Inc. J. Appl.

AbstractThe reaction of 4‐chloro‐1,2‐dimethyl‐4‐supersilylsila‐1‐cyclopentene (2 a) with Li[NiPr2] at −78 °C results in the formation of the formal 1,4‐addition product of the silacyclopentadiene derivative 3,4‐dimethyl‐1‐supersilylsila‐1,3‐cyclopentadiene (4 a) with 2,3‐dimethyl‐4‐supersilylsila‐1,3‐cyclopentadiene (5 a). In addition the respective adducts of the Diels–Alder reactions of 4 a+4 a and 4 a+5 a were obtained. Compound 4 a, which displays an s‐cis‐silacyclopentadiene configuration, reacts with cyclohexene to form the racemate of the [4+2] cycloadduct of 4 a and cyclohexene (9). In the reaction between 4 a and 2,3‐dimethylbutadiene, however, 4 a acted as silene as well as silacyclopentadiene to yield the [2+4] and [4+2] cycloadducts 10 and 11, respectively. The constitutions of 9, 10, and 11 were confirmed by NMR spectroscopy and their crystal structures were determined. Reaction of 4‐chloro‐1,2‐dimethyl‐4‐tert‐butyl‐4‐silacyclopent‐1‐ene (2 c) with KC8 yielded the corresponding disilane (12), which was characterized by X‐ray crystal structure analysis (triclinic, P$\bar 1$). DFT calculations are used to unveil the mechanistic scenario underlying the observed reactivity.
Thermal‐Induced Formation of a Three‐Dimensional Nanoplasmonic Sensor from Ag Nanocubes with High Stability and Reusability

Published: March 2014

AbstractNanoplasmonic sensors based on the localized surface plasmon resonance (LSPR) of noble metal nanoparticles have many advantages, such as real‐time detection, no need for reagent labelling, and no use of complicated equipment. However, the nanoplasmonic sensors with two dimensional structures usually suffer from a low LSPR signal and thus low sensitivity due to the low density of the nanoparticles. In addition, complicated surface functionalization is always required to suppress the non‐specific binding of the analyst to the substrate of the sensor, because the two types of surface, that is, metal and substrate surfaces, are simultaneously exposed to the reaction medium. To overcome these problems, an innovative thermal‐induced method has been proposed in the present work, to construct three dimensional (3D) nanostructure of Ag nanocubes on both surfaces of the substrate by using the unique amphiphilic property of 2‐diethylaminoethanethiol. The prepared nanoplasmonic sensor is highly sensitive due to the high density of 3D structure of the nanoparticles and the low non‐specific binding since only one type of surface is exposed. To enhance the stability of the sensor, a thin SiO2 overlayer was formed on the surface without using an additional coupling agent. Furthermore, the NiII‐nitriloacetic acid (NiII‐NTA) complex was covalently bound on the surface, so that the regeneration and reuse of the sensor becomes easy. Therefore, the easy fabrication, high stability, and good reusability of this 3D LSPR sensor makes our method competitive for the development of nanoplasmonic sensors.
A One‐Pot O‐Phosphinative Passerini/Pudovik Reaction: Efficient Synthesis of Highly Functionalized α‐(Phosphinyloxy)amide Derivatives

Published: March 2014

AbstractA one‐pot O‐phosphinative Passerini/Pudovik reaction has been developed, based on reacting aldehydes, isocyanides, and phosphinic acids followed by the addition of second aldehydes to form the corresponding α‐(phosphinyloxy)amide derivatives. This is the first reported instance of a Passerini‐type, isocyanide‐based multicomponent reaction using a phosphinic acid instead of a carboxylic acid. The nucleophilicity of the phosphinate group allows a subsequent catalytic Pudovik‐type reaction, affording the highly functionalized α‐(phosphinyloxy)amide derivative in high yield. A wide range of aldehydes and isocyanides are applicable to this reaction.
