Untold Narratives and Reimagined Histories: The Work of Dawoud Bey and Titus Kaphar
Authors: nemeth jeanne , Willcox Libba
Published: August 2023

This article provides high school art room activities that address the past, contemplate the present, and encourage teaching for change. The authors introduce two contemporary artists, Dawoud Bey and Titus Kaphar, whose work embraces the idea of untold narratives and juxtapose their artwork to instigate difficult but necessary conversations about America’s racial past and present. Bey’s photographic narratives and Kaphar’s innovative paintings unveil truths and histories of Black American culture that have long been neglected. Each juxtaposition is accompanied by background information, discussion questions, and ideas designed to engage students in critical dialogue about race and racism. These conversations are followed by creative writing, and artmaking processes encouraging students to learn from our histories to reimagine our present.

Objectives

Myxomas are the most common primary tumors of the adult heart and should be considered in the differential diagnosis of intracavitary cardiac masses, along with thrombi and vegetations.

Methods

We report a case of a 64-year-old obese, hypertensive woman, who presented with dyspnea on moderate exertion as well as fatigue. The patient was admitted to our hospital after the discovery on transthoracic echocardiography of an intracardiac mass, which was highly suggestive for a left atrial myxoma.

Results

On admission, the patient presents no abnormalities on physical exam, with blood tests showing only slight deviations in the lipid profile. The ECG presents a normal sinus rhythm of 80/min with two premature ventricular contractions and a premature atrial contraction. Transthoracic echocardiography revealed the presence of a well-defined, pediculated, left atrial mass attached to the interatrial septum, measuring 25/17 mm, with no apparent interference in mitral valve motion. We supplemented our investigations with the use of transesophageal echocardiography which further defined the dimensions and location of the tumor, while also showing the presence of an atrial septal aneurysm associated to two small atrial septal defects measuring 6 mm and 7 mm respectively, with a left to right shunt. Cardiac CT examination confirmed the benign aspect of the mass and offered important anatomical elements, useful in preoperative planning. The patient was, therefore, admitted to our Cardiovascular Surgery department, where a successful surgical resection of the tumor was performed, without any local or systemic complications. The differential diagnosis of this mass included intracavitary thrombi, vegetations, as well as other histological subtypes of benign or malignant tumors, while the presence of an atrial septal defect, which represents a possible source of paradoxical emboli, provided an additional challenge.

Conclusions

This complicated case stands out due to its particular echocardiographic appearance and emphasizes the importance of a comprehensive evaluation in both the differential diagnosis and preoperative assessment.

A book is the result of someone's work in the form of a collection of papers containing articles intended for publication. One of the benefits of books is that they can open people's horizons and can educate reason, thoughts and faith. Indonesia is ranked 60 out of 61 countries with reading interest problems causing low public interest in reading. One of the factors that can be taken into consideration for interest in reading in Indonesia is the difficulty in finding books to read because the many kinds of books in circulation make it difficult for readers to decide which books to read, besides that readers only want to read books with the best reputation. The purpose of creating a book recommendation system is to make it easier to find fiction-type books to read. The data used in this design are book data and rating data from Kaggle. This design uses one of the recommendation system methods, namely collaborative filtering. Collaborative filtering is a recommendation method that calculates similarity between items by users to make choices.

PERAN HIDRASI KULIT DAN PERBAIKAN SAWAR KULIT PADA XEROSIS DAN PRURITUS DI USIA LANJUT
Authors: Wijayadi Linda Julianti , Wardoyo Aryananda Haris
Published: August 2023

Pendahuluan: Proses penuaan kulit menyebabkan perubahan kulit pada usia lanjut. Terjadi penurunan kadar hidrasi dan perubahan sawar kulit yang akan bermanifestasi pada perubahan struktur kulit dan menimbulkan xerosis serta pruritus. Metode Penelitian: Literatur dikumpulkan secara elektronik maupun tertulis dari PubMed, Sinta dan buku ajar dermatologi geriatrik dengan total 46 literatur berbahasa Inggris maupun Indonesia. Hasil dan Pembahasan: Pada kulit usia lanjut terjadi penurunan kemampuan kulit untuk mempertahankan air pada stratum korneum, sehingga menyebabkan penurunan kadar hidrasi kulit. Proses diferensiasi sel kulit pada usia lanjut lebih lambat dibandingkan usia muda, hal ini menyebabkan terganggunya permeabilitas kulit dan penurunan fungsi sawar kulit. Perubahan fisiologis tersebut dapat diperberat dengan adanya penyakit metabolik pada usia lanjut berupa diabetes melitus. Tatalaksana xerosis dan pruritus dapat berupa topikal dan oral yang bersifat simptomatik dengan tujuan meningkatkan hidrasi kulit dan menunjang struktural sawar kulit. Kesimpulan dan Saran: Peran hidrasi dan sawar kulit sangat penting dalam menjaga kelembaban kulit pada orang usia lanjut. Penurunan fungsi sawar kulit dan kadar hidrasi kulit dapat disebabkan oleh karena faktor ekternal maupun internal, sehingga dibutuhkan tata laksana yang komprehensif pada kulit orang usia lanjut untuk menjaga kadar hidrasi kulit dan sawar kulit.

During the vertical descent and landing of a launcher first stage with the aid of retropropulsion, commonly two main propulsive deceleration maneuvers are performed: the reentry burn in high altitudes at hypersonic to supersonic speeds and the landing burn shortly before touchdown at transonic to subsonic speeds. In the frame of the EU-funded H2020 project Retro Propulsion Assisted Landing Technologies (RETALT), the unsteady aerodynamics of those retropropulsion phases were studied. This paper presents results of experiments performed in the Hypersonic Wind Tunnel Cologne on the hypersonic reentry burn. The exhaust plume was simulated with pressurized air. Proper orthogonal decomposition was performed on high-speed schlieren videos, and spectral analyses of the time histories of the resulting modes were compared to the frequency content found in high-frequency pressure measurements. Dominant frequencies were found in the proper orthogonal decomposition modes for one and for three active engines. In the pressure measurements, dominant frequencies could only be observed for three active engines. The normalized pressure fluctuations are in the range of 0.002–0.012. Additionally, a good scaling of the pressures on the base area and in the wake of the configuration with the total pressure downstream of the bow shock could be confirmed, in the sense that the ratio of the local surface pressure to the total pressure downstream of the bow shock match for varying freestream Mach numbers.

OBJECTIVE: To develop a new patient-reported outcome measure (PROM) assessing TENDINopathy Severity of the Achilles (TENDINS-Achilles) and evaluate its content validity.

DESIGN: Mixed-methods, modified Delphi.

METHODS: We performed 1 round of semistructured one-on-one interview responses with professionals and patients, for initial item generation. This was followed by 1 round of survey responses for professionals and a final round of semistructured one-on-one interviews with patients. The work culminated in a PROM to quantify Achilles tendinopathy severity under the core health domain of disability. Participants identified 3 subdomains contributing to the severity of disability of Achilles tendinopathy: pain, symptoms, and functional capacity.

RESULTS: All 8 patient participants invited to participate were enrolled. Forty professional participants (50% women, six different continents) were invited to participate and 30 were enrolled (75% response rate). Therefore, a total of 30 professionals and 8 patients were included within this study. Following 3 rounds of qualitative or quantitative feedback, this study has established the content validity of TENDINS-A (good relevance, comprehensibility, and comprehensiveness) as a new PROM to assess the severity of Achilles tendinopathy, which assesses aspects of pain, symptoms, and functional capacity.

CONCLUSION: TENDINS-A has established content validity and is appropriate for use with clinical and research populations. We recommend users interpret TENDINS-A results cautiously, until further testing evaluates the most appropriate scoring scale, reliability, construct validity, criterion validity, and responsiveness of TENDINS-A. Until these psychometric properties are established, we suggest using TENDINS-A alongside existing tools. J Orthop Sports Phys Ther 2024;54(1):70-85. Epub 24 August 2023. doi:10.2519/jospt.2023.11964

Adsorption of glycerol is the first step in many catalytic reactions to transform glycerol that was formed as biodiesel byproduct into valuable products. Among many feasible catalysts, Cu seems to be a good choice due to its abundance and cost consideration, though extensive studies are needed to evaluate the performance of Cu catalysts on glycerol transformation. Density functional theory (DFT) calculations and van der Waals corrected calculations (DFT-D3) were therefore performed in this work to study the adsorption of glycerol on the three most abundant copper surfaces: Cu(111), Cu(100), and Cu(110). Inclusion of the van der Waals interactions resulted in higher adsorption energies and shorter Cu-O bond distances. The most favorable adsorption location was determined to be the Cu(110) long bridge site. The strongest adsorption is the atop site on the Cu(111) and the hollow site on the Cu(100), though the other adsorption sites are also very favorable.

A new curved π-conjugated molecule-1-fluorosumanene (1) was designed and synthesized which possesses one fluorine atom on the benzylic carbon of sumanene. This compound is able to exhibit bowl inversion in solution, leading to the formation of two diastere-omers 1endo and 1exo with different dipole moment. Experimental and theoretical investigation revealed energetical relationship among 1exo, 1endo and solvent to realize the control of exo:endo ratio in the single crystals of 1 by the correct choice of the crystalliza-tion solvent. Significantly, the molecular dynamics (MD) simulations revealed that 1exo positively worked for elongation of the stacking structure and the final exo:endo ratio was affected by the relative stability difference between 1endo and 1exo derived by solv-ation. Such controllable exo:endo ratio of 1 realized the preparation of unique materials showing totally different dielectric response from the same molecule 1 just by changing crystallization solvent.

Electrochemical experiments and theoretical calculations have shown that Pd-based metal hydrides can display good performance in the CO2 reduction reaction (CO2RR). To explore higher-performance catalysts, Pd-based alloy hydrides PdxM1–xHy are studied in this work. Our previous work on doped-PdH showed that doping Ti and Nb into PdH can improve the CO2RR activity, suggesting that the Pd alloy hydrides with better performance are likely to be found in the Pdx Ti1–xHy and PdxNb1–xHy phase space. However, the complex nature of the compositional and structural phase space that includes different compositions of alloy hydrides, different concentrations of the metal element and H of alloy hydrides, different adsorption sites, and different adsorbates, makes it intractable to screen out the stable and active PdxM1–xHy catalysts using density functional theory (DFT) calculation. Herein, an active learning cluster expansion (ALCE) surrogate model equipped with Monte Carlo simulated annealing (MCSA), a CO* filter and a kinetic model are used to identify promising Pdx Ti1–xHy and PdxNb1–xHy catalysts with high stability and superior activity. Finally, 24 stable and active candidates of Pdx Ti1–xHy and 6 active candidates of PdxNb1–xHy are found using our approach. Among them, the Pd0.23Ti0.77H, Pd0.19Ti0.81H0.94 and Pd0.17Nb0.83H0.25 display superior current densities of approximately 5.1, 5.1 and 4.6 μAcm−2 at −0.5V overpotential, respectively, which are significantly higher than that of PdH at 3.7 μAcm−2. Their free energy diagram shows that their HOCO* binding is not too weak, while their CO* binding is not too strong, resulting in enhanced activities. The statistical analysis shows that the binding energies are mainly contributed by the elements Ti/Nb and H. Hence, three candidates, Pd0.23Ti0.77H, Pd0.19Ti0.81H0.94, and Pd0.17Nb0.83H0.25, are recommended in this work.

Electric fields play a key role in enzymatic catalysis and can enhance reaction rates by 100,000-fold, but the same rate enhancements have yet to be achieved in thermochemical heterogeneous catalysis. Herein, we probe the influence of catalyst potential and interfacial electric fields on heterogeneous Brønsted acid catalysis. We observe that variations in applied potential of ~360 mV lead to a ~100,000-fold rate enhancement for 1-methylcyclopentanol dehydration catalyzed by carbon-supported phosphotungstic acid. Mechanistic studies support a model in which the interfacial electrostatic potential drop drives quasi-equilibrated proton transfer to the adsorbed substrate prior to rate-limiting C-O bond cleavage. Large increases in rate with potential are also observed for the same reaction catalyzed by Ti/TiOyHx and for the Friedel Crafts acylation of anisole with acetic anhydride by carbon-supported phosphotungstic acid. This work highlights the important role interfacial electrochemical potential can play in Brønsted acid catalysis.

Published: August 2023

Purpose: The Management Control System (MCS) has a crisis of meaning nowadays. Moreover, banking institutions with the highest risk level with liquid assets require a more comprehensive MCS. This research aims to develop an MCS concept that can be applied in traditional financial institutions as a more humane control system.
 
Theoretical framework: This study provides a critique of the legitimacy theory related to MCS. An institution exists to gain legitimacy, but with a flawed control system, organizations practice creative accounting to gain a trust.
 
Design/Methodology/Approach: This is qualitative research with a case study in one of the traditional banking institutions in Bali called Village Credit Institutions (LPD). The research paradigm uses postmodernism by adopting Lyotard's views using the binary opposition synergy methodology.
 
Findings: The study results found that the construction of MCS was more suitable for use in the traditional banking sector. Organizations must pay attention to a sense of family, open management, and communication to create a sustainable organization. Have a good harmonious relationship with God, humans, and the environment.
 
Research, practical & social implications: The practical implication that can be contributed to this research is implementing a culture-based control system in traditional financial institutions. A control system formed from people's habits can create absolute goal congruence.
 
Originality/Value: This research produces a form of construction of a new model in MCS that has never existed before to create harmony with humans, the environment, and God.
