Objectives

Carpal tunnel syndrome (CTS) stands as the most prevalent upper extremity entrapment neuropathy, with a multifaceted etiology encompassing various risk factors. This study aimed to investigate whether anthropometric measurements of the hand, grip strength, and pinch strength could serve as predictive indicators for CTS through machine learning techniques.

Methods

Enrollment encompassed patients exhibiting CTS symptoms (n = 56) and asymptomatic healthy controls (n = 56), with confirmation via electrophysiological assessments. Anthropometric measurements of the hand were obtained using a digital caliper, grip strength was gauged via a digital handgrip dynamometer, and pinch strengths were assessed using a pinchmeter. A comprehensive analysis was conducted employing four most common and effective machine learning algorithms, integrating thorough parameter tuning and cross-validation procedures. Additionally, the outcomes of variable importance were presented.

Results

Among the diverse algorithms, Random Forests (accuracy of 89.474%, F1-score of 0.905, and kappa value of 0.789) and XGBoost (accuracy of 86.842%, F1-score of 0.878, and kappa value of 0.736) emerged as the top-performing choices based on distinct classification metrics. In addition, using variable importance calculations specific to these models, the most important variables were found to be wrist circumference, hand width, hand grip strength, tip pinch, key pinch, and middle finger length.

Conclusion

The findings of this study demonstrated that wrist circumference, hand width, hand grip strength, tip pinch, key pinch, and middle finger length can be utilized as reliable indicators of CTS. Also, the model developed herein, along with the identified crucial variables, could serve as an informative guide for healthcare professionals, enhancing precision and efficacy in CTS prediction.

Published: April 2024

Central nervous system (CNS) tumors, due to their unique locations, pose a serious threat to human health and present challenges to modern medicine. These tumors exhibit notable epidemiological characteristics across various ethnicities, regions, and age groups. This study investigated the trend of disease burden of CNS tumors in China from 1990–2019 and predicted the incidence and death rate from 2020–2030. Employing data from the 2019 Global Burden of Disease (GBD) database, we utilized key indicators to scrutinize the disease burden associated with CNS tumors in China. The analysis employed the Joinpoint model to track the trend in disease burden, calculating both the annual percentage change (APC) and average annual percentage change (AAPC). Additionally, the Matlab software facilitated the creation of a gray model to forecast the incidence and death rate of CNS tumors in China spanning from 2020 to 2030." In 2019, the age-standardized incidence rate, prevalence rate, death rate, and disability-adjusted life years (DALYs) associated with CNS tumors in China were among the high level in the world. The standardized prevalence rate and DALYs of CNS tumors in China residents showed a stable fluctuation trend with age; however, age-standardized death and incidence rate demonstrated a generally upward trend with age. In China, the age-standardized prevalence and incidence rate of males were lower than those for female residents, while the age-standardized death rate and DALYs among males surpassed those of females. From 1990–2019, the age-standardized prevalence and incidence rate of CNS tumors in China exhibited an increasing trend. The age-standardized death rate and DALYs showed a contrasting trend. According to the gray model’s prediction, incidence rate of CNS tumors would continue rising while the death rate is expected to decline in China from 2020–2023. The burden of CNS tumors in China has shown an upward trajectory, posing significant challenges to their treatment. It is necessary to pay attention to tertiary prevention, start from the perspective of high-risk groups and high-risk factors to reduce the burden of disease, and achieve "early detection, early diagnosis, and early treatment".

This study tackles the complex task of integrating wind energy systems into the electric grid, facing challenges such as power oscillations and unreliable energy generation due to fluctuating wind speeds. Focused on wind energy conversion systems, particularly those utilizing double-fed induction generators (DFIGs), the research introduces a novel approach to enhance Direct Power Control (DPC) effectiveness. Traditional DPC, while simple, encounters issues like torque ripples and reduced power quality due to a hysteresis controller. In response, the study proposes an innovative DPC method for DFIGs using artificial neural networks (ANNs). Experimental verification shows ANNs effectively addressing issues with the hysteresis controller and switching table. Additionally, the study addresses wind speed variability by employing an artificial neural network to directly control reactive and active power of DFIG, aiming to minimize challenges with varying wind speeds. Results highlight the effectiveness and reliability of the developed intelligent strategy, outperforming traditional methods by reducing current harmonics and improving dynamic response. This research contributes valuable insights into enhancing the performance and reliability of renewable energy systems, advancing solutions for wind energy integration complexities.
The geography of corporate fake news
Authors: Darendeli Alper , Sun Aixin , Tay Wee Peng
Published: April 2024

Although a rich academic literature examines the use of fake news by foreign actors for political manipulation, there is limited research on potential foreign intervention in capital markets. To address this gap, we construct a comprehensive database of (negative) fake news regarding U.S. firms by scraping prominent fact-checking sites. We identify the accounts that spread the news on Twitter (now X) and use machine-learning techniques to infer the geographic locations of these fake news spreaders. Our analysis reveals that corporate fake news is more likely than corporate non-fake news to be spread by foreign accounts. At the country level, corporate fake news is more likely to originate from African and Middle Eastern countries and tends to increase during periods of high geopolitical tension. At the firm level, firms operating in uncertain information environments and strategic industries are more likely to be targeted by foreign accounts. Overall, our findings provide initial evidence of foreign-originating misinformation in capital markets and thus have important policy implications.

Published: April 2024

Remimazolam’s rapid onset and offset make it an innovative sedative for use during regional anesthesia. However, its respiratory safety profile is not well understood. We compared the continuous infusion of remimazolam with commonly used sedatives, propofol and dexmedetomidine, after regional anesthesia. In this retrospective study, the incidence of apnea (>10 seconds) was assessed in patients who underwent orthopedic surgery under regional anesthesia and received moderate to deep sedation using continuous infusion of remimazolam (group R: 0.1 mg/kg in 2 minutes followed by 0.5 mg/kg/hr). The incidence was compared with that of propofol (group P: 2–3 μg/mL target-controlled infusion) and dexmedetomidine (group D: 1 μg/kg in 10 minutes followed by 0.4–1 μg/kg/hr). Propensity score weighted multivariable logistic regression model was utilized to determine the effects of the sedative agents on the incidence of apnea. A total of 634 (191, 278, and 165 in group R, P, and D) cases were included in the final analysis. The incidence of apnea was 63.9%, 67.3%, and 48.5% in group R, P, and D, respectively. The adjusted odds ratios for apnea were 2.33 (95% CI, 1.50 to 3.61) and 2.50 (95% CI, 1.63 to 3.85) in group R and P, compared to group D. The incidence of apnea in patients receiving moderate to deep sedation using continuous infusion of remimazolam with dosage suggested in the current study was over 60%. Therefore, careful titration and respiratory monitoring is warranted.
Using Museum collections to assess the impact of industrialization on mussel (Mytilus edulis) calcification
Authors: Melbourne Leanne A. , Goodkin Nathalie F.
Published: April 2024

Mytilus edulis is a commercially and ecologically important species found along the east coast of the United States. Ecologically, M. edulis improves water quality through filtration feeding and provides habitat formation and coastal protection through reef formation. Like many marine calcifiers, ocean warming, and acidification are a growing threat to these organisms—impacting their morphology and function. Museum collections are useful in assessing long-term environmental impacts on organisms in a natural multi-stressor environment, where acclimation and adaptation can be considered. Using the American Museum of Natural History collections ranging from the early 1900s until now, we show that shell porosity changes through time. Shells collected today are significantly more porous than shells collected in the 1960s and, at some sites, than shells collected from the early 1900s. The disparity between porosity changes matches well with the warming that occurred over the last 130 years in the north Atlantic suggesting that warming is causing porosity changes. However, more work is required to discern local environmental impacts and to fully identify porosity drivers. Since, porosity is known to affect structural integrity, porosity increasing through time could have negative consequences for mussel reef structural integrity and hence habitat formation and storm defenses.
Both religious and secular ethics to achieve both happiness and health: Panel data results based on a dynamic theoretical model
Authors: Zagonari Fabio
Published: April 2024

This paper evaluates the direct and indirect impacts (and their interactions) of individual and social ethics from (primary, secondary, tertiary) education and religion (Buddhism, Christianity, Hinduism, Islam, Judaism) on health and happiness in alternative religious contexts (majority and minority religions) and for alternative education policies (gross enrolment and per-student expenditure). It also specifies the time lag for the short-run indirect impact (and its size) of happiness on health and the long-run equilibria of both happiness and health. The statistical results show that there is no religious or secular ethics with beneficial impacts on both happiness and health at both the individual and social levels. Next, education policies have similar impacts on both happiness and health in all religious contexts, while most religious ethics have larger beneficial impacts on health and happiness if coupled with social and individual education policies, respectively. Combined statistical and analytical results show that the largest short-run indirect impact of happiness on health occurs after 4 years, where 1 out of 10 points of happiness produces approximately 3 additional years of healthy life expectancy at birth. Next, the long-run equilibria of both happiness and health are globally stable and are achieved after 8 years through oscillation dynamics.
The significant object: The artistic imaginary of Madeira Island embroidery
Authors: Nolasco Ana
Published: April 2024

In this article, I reflect on the way in which the memory of the disappearance of embroidery – as a manufacturing activity and, as a consequence, as the genus of social fabric and socio-economic relations – fosters the construction of a local identity and feeds the creation of a new symbolic language. I analyse how the division between the ‘traditional’ and the ‘contemporary’ is the result of a western culture that creates a sharp divide in time wherein everything that precedes it is in the past, and therefore fixed. Following this line of thought, craftsmanship has been associated with the traditional (i.e. unchanging), and art or design with the contemporary. By mapping the evolution of the Madeiran embroidery imaginary, I argue that this division is a historical construct. Seeing the embroidery as both an art and a craft enables a process of reinterpretation and invention, which enhances the creation of new imaginaries and alternative futures.
Material, gesture and touch: Ingrid Murphy, the playful ceramicist
Authors: Potter Gemma
Published: April 2024

As a ceramicist, Ingrid Murphy’s work explores the material culture of ceramics and human connection through technological intervention. This article discusses the key themes of ‘ceramics as interface’ and ‘augmented ceramics’ seen through much of Murphy’s practice. Murphy centres her work around the audience experience, subverting our relationship with the domestic and familiar. Through employing and exploiting aspects of digital technology, Murphy sees the objects she creates as ‘vehicles for naughtiness’, inserting herself physically and virtually into digital 3D scans of commonplace historical ceramic objects. Having exhibited work internationally, Murphy uses physical computing and technology employed within the Internet of Things (IoT) to connect viewers of her pieces through object-to-object communication. The notion of ‘ceramics as interface’ is explored further by exploiting the conductive qualities of gold lustre and liquid graphite, effectively turning her pots into capacitive touch sensors that generate interactive soundscapes that respond to gesture and physical interaction with resonant sound. The unexpected and delightful experiences that result from interacting with these objects typify Murphy’s work and playful approach to ceramics.
Ink Sack (for Bridget)
Authors: Pickering Kate
Published: April 2024

This contribution deploys experimental writing as part of a visual art practice to take up themes of embodied practices of writing, writing as a practice of care and writing/reading as affective, immersive flow. It weaves a personal account of the loss of my Ph.D. supervisor and friend, the curator, writer and scholar Bridget Crone into liquid experiences from my past, and quotes from Bridget’s text ‘Deep sea squid: A phase problem’ (2013) to consider writing as reparative in the face of grief. My writing method both refers to liquidity and is liquid in form, water and ink flowing across boundaries of different bodies, places and times. ‘Ink Sack’ also reproduces the tentacular reach of Bridget’s influence: her ‘Deep sea squid’ text was the inspiration for the artist Anna Barham in her 2013 work Double Screen (Not Quite Tonight Jellylike), which Bridget then responded to in her essay on Barham’s work Talking Squid (2013).
0ctoGANN: A fiction
Authors: Roberts Maggie
Published: April 2024

0ctoGANN is an experimental fiction, operating through multi-sensory imagination, that draws on my experiences of freediving in the Great African Kelp Forest off the coast of Capetown – home to the common octopus – together with an ongoing commitment to refiguring AI. The writing emerges from imagining into the lifeworld of the octopus, made possible by my immersion in the ocean flows and surges. It is a call to (western) human-centric perspectives to embrace knowledge-gathering through embodied intelligence, and to consider how AI might be trained on the decentralized distributed somatic tendencies of the octopus rather than on current corporate marketing/surveillance agendas. It is also a paean to this protean, incoherent (to humans) and experimental creature, living in a constant state of change and fluidity. 0ctoGANN is certainly an expression of hope for the contemporary world, though not necessarily human.
La tergiversación de las fuentes literarias en la filmografía de Jesús Franco: de la adaptación al cine
Authors: Casares Carmona Esther
Published: April 2024

Entre la profusión de acercamientos teóricos de la cinematografía con respecto de la literatura se plantea esta tesis. En particular, sobre las reescrituras fílmicas del cineasta Jesús Franco, el más prolífico cineasta español con un total de ciento ochenta y ocho títulos. Los mecanismos de transferencia que explican el paso del texto escrito, base de varias películas del conocido cineasta, hasta llegar al producto final contemplado por el espectador en la pantalla. La bibliografía en torno al tema de la adaptación es considerable y sigue en aumento; sin embargo, no se ha tratado hasta el momento la reescritura cinematográfica en Jesús Franco, de ahí la razón de que esta tesis pueda resultar un tema de estudio novedoso con posibilidades de ulteriores líneas de investigación. Esta tesis podría englobarse dentro del área del cine de terror con la figura central de Jesús Franco, por representar un gran exponente del cine gótico español debido a la utilización sistemática del género, cuyas fuentes principales encuentran su origen en el cine y sobre todo en la novela gótica anglosajona. Las fuentes literarias en la filmografía de Jesús Franco son transgredidas para crear una película completamente diferente no sólo con respecto de la obra literaria sino también de la forma de hacer cine que realizaban otros autores coetáneos a Jesús Franco que a diferencia de Franco -que vivía y rodaba en Estados Unidos- vivieron y realizaron películas en España en plena censura.

Objetivo: Descrever a distribuição espacial e temporal da oferta de fonoaudiólogos na Atenção Primária à Saúde (APS) e de atendimentos individuais e atividades coletivas no Núcleo Ampliado de Saúde da Família e Atenção Básica (NASF-AB) e os impactos com a pandemia de Covid-19 nas Unidades da Federação (UFs) do Brasil entre 2016 e 2021. Método: Estudo ecológico, descritivo, com dados secundários, no qual foram calculadas taxas de fonoaudiólogos na APS e de atendimentos individuais e atividades coletivas no NASF-AB. As taxas foram representadas espacialmente em mapas coropléticos, com Análise Exploratória de Dados Espaciais pelo software QGIS. Foi verificada a evolução da oferta das taxas entre 2019 e 2020 e realizada a análise descritiva dos tipos de atividades coletivas registrados. Resultados: Observou-se variabilidade nas taxas ao longo dos anos, com maiores desempenhos nas UFs das regiões Nordeste e Sudeste e menores amplitudes nas UFs da região Norte. Entre 2019 e 2020, houve declínio nacional na evolução das taxas, acompanhado por reduções mais expressivas no Ceará (-16,82%), para a oferta de fonoaudiólogos na APS; no Acre (-93,99%), para os atendimentos individuais; e em Roraima (-97,20%), para as atividades coletivas. O atendimento em grupo foi a atividade coletiva predominante no Brasil, enquanto a mobilização social foi a menos exercida. Conclusão: Os resultados apontam discrepâncias na oferta das taxas de fonoaudiólogos na APS e de atendimentos individuais e atividades coletivas no NASF-AB e singularidades na distribuição dessas atividades entre as UFs. A pandemia ocasionou efeitos acentuados nas ações de fonoaudiólogos no NASF-AB.
La Unión Europea dentro de la OMC: ¿paradigma de liderazgo geopolítico en las relaciones internacionales?
Authors: Baena Rojas José Jaime
Published: April 2024

Desde la configuración del sistema multilateral de comercio se ha promovido la disminución de los obstáculos y la no discriminación al comercio entre los Estados miembros. No obstante las rondas de negociaciones en el régimen del GATT (del inglés General Agreement on Tariffs and Trade), y dentro de la Organización Mundial del Comercio (OMC), que han apuntado a reducir el proteccionismo injustificado además de crear normas comerciales acordes con las prácticas actuales, se ha tendido a presentar diversos reveses de consenso. Es en este sentido que ciertos acuerdos comerciales, que subsecuentemente dan origen a organizaciones internacionales, toman más notoriedad como herramientas de regulación complementaria y terminan restando preeminencia al multilateralismo de la OMC. Este es el caso de la Unión Europea (UE) que no solo comparte su génesis con la OMC tras el fin de la Segunda Guerra Mundial, sino que además ha logrado dar sobresalientes pasos, consolidándose incluso como un paradigma de liderazgo geopolítico. Es así como este trabajo orienta el estudio a una metodología multidisciplinar que desde lo jurídico e histórico caracteriza la influencia político-comercial de la UE como integración económica dentro del comercio internacional. Para ello, se consideran las disputas registradas dentro del Órgano de Solución de Diferencias (OSD) y se identifican también los acuerdos comerciales que esta ha firmado con otros países. Lo anterior evidencia su influencia como actor determinante, además de referente categórico, para la cooperación internacional y la gobernanza global, dado su impacto directo en la dinámica del comercio mundial y en las relaciones internacionales contemporáneas.

Weighted estimates for product singular integral operators in Journé’s class on RD-spaces
Authors: Zheng Taotao , Xiao Yanmei , Tao Xiangxing
Published: April 2024

An RD-space 𝑀 is a space of homogeneous type in the sense of Coifman and Weiss with the additional property that a reverse doubling property holds in 𝑀.
In this paper, firstly, the authors give the Plancherel–Pôlya characterization of product weighted Triebel–Lizorkin spaces and product weighted Besov spaces on RD-spaces and make some estimates for the product singular integral operators in Journé’s class on these function spaces.
As a result of these conclusions, they present some sufficient conditions for the boundedness of product singular integral operators on the product Lipschitz spaces and product weighted Hardy spaces.
Secondly, by the boundedness of lifting and projection operators, they also obtain that the dual spaces of the product weighted Hardy spaces are product weighted Carleson measure spaces.
Using the idea of dual, the authors obtain the weighted boundedness of singular integral operators on the product weighted Carleson measure spaces.
Defining “Romans” in the Late Antique Near East: Some Preliminary Thoughts on the “Romans” in Sūrat al-Rūm
Authors: Kavvadas Nestor
Published: April 2024

In the opening lines of the sūrah named after the “Romans,” Q Rūm 30, the qurʾānic preacher expresses his solidarity with the “Romans” who had then been defeated by the Persian army. In seeking to better understand these verses, one may start with the question: Who exactly are the “Romans” here? “Roman” was a broad, multifaceted term, as Yannis Stouraitis has lately pointed out, based mainly on sources written after the seventh century and stemming from the Greek-speaking “West” of the Byzantine Empire. In this study, using mainly Syriac sources but also some hitherto unnoticed Greek testimonies coming from the Near East, this semantic variability of the word “Roman” is shown to further expand when going East. Like in most Syriac sources, “Romans” in Q Rūm primarily means members of the Byzantine army (and state apparatus), be they ethnic Greeks, Syrians, or Arabs. At the same time, the “Romans” of this sūrah are all inhabitants, all “citizens” of the Byzantine Empire – not just its armies and magistrates. This latter sense corresponds to the broader sense in which “Romans” is used not only in Syriac, but also in Greek sources (and in other languages of the Late Antique Near East). That broader sense is one that we find in a definition by the Damascene Sophronios of Jerusalem, according to whom “Roman” is anyone “stemming from a city subject to the Romans.”

Another qurʾānic passage that refers to the Byzantines (though without naming them), which has very much to do with the same geopolitical context of the Byzantine-Persian wars, Q Māʾidah 5:17, seems to criticize a “Byzantine” confidence in the invincibility of Christ and Mary. Why does the Qurʾān chose to name the Romans when expressing solidarity with them, yet leave them unnamed when criticizing them? Could it be the case that this difference between naming the “Romans” and leaving them unnamed is somehow meant to show that the solidarity with the “Romans,” as declared expressis verbis in the Sūrat al-Rūm, concerns the entire Byzantine world whereas the sharp criticism in al-Māʾidah is not general in the same sense?

Objectives

Prevalence of diabetes distress and mental health comorbidities among adolescents with type 1 diabetes (T1D) is high. Despite recommendations for routine psychosocial risk assessment, there is little guidance for their implementation. This study aims to describe the implementation and baseline outcomes of the Mind Youth Questionnaire (MY-Q), a validated psychosocial screening tool for health-related quality of life (QoL) including mood, among adolescents living with T1D.

Methods

Adolescents aged 13–18 years completed the MY-Q from October 1, 2019–April 1, 2023. Baseline characteristics, MY-Q results including categories flagged positive (noting possible areas of concern), debrief duration, and frequency of social work or mental health referral were collected and analyzed using descriptive statistics.

Results

A total of 343 adolescents (mean age 15.3 years; 52 % female) completed a baseline MY-Q. Median overall MY-Q debrief time (IQR) was 10.0 min (6.0, 20.0). About 290 (84.5 %) adolescents had at least one of seven categories flagged, most commonly “Family” (61 %). About 30 % of adolescents had “Mood” flagged, and 2.9 % of adolescents were referred to mental health following debrief.

Conclusions

Without the need for additional resources, implementation of the MY-Q in a pediatric tertiary care diabetes clinic successfully identified QoL issues and mental health concerns among adolescents with T1D.

Objectives

Sickle cell disease (SCD) occurs in 2.8 % of our Jamaican antenatal population with homozygous HbSS being most associated with adverse maternal and perinatal outcomes.

Methods

A retrospective comparative analysis of HbSS, HbSC and HbSβThal pregnancy outcomes at the University Hospital of the West Indies (UHWI) between January 2012 and December 2022 was conducted.

Results

Of 120 patients (138 pregnancies), obesity occurred in 36 % (20/56) of the ‘non-HbSS’ group, i.e. HbSβThal (55 %, 5/9) and HbSC (32 %, 15/47) combined vs. 9.7 % of the HbSS (8/82). HbSS patients had more crises requiring transfusions, acute chest syndrome (ACS), maternal ‘near-misses’ (OR=10.7, 95 % 3.5–32.3; p<0.001), hospitalizations (OR 7.6, 95 % CI 3.4–16.9; p<0.001), low birth weight (LBW) neonates (OR 3.1, 1.1–8.9; p=0.037) and preterm birth (OR=2.6, 1.2–5.8; p=0.018) compared to HbSC and HbSβThal. Low dose aspirin was prescribed in 43 %. Logistic regression showed those NOT on aspirin (n=76) had more miscarriages (22 v. 2 %), were LESS likely to have a live birth (75 v. 95 % (0.2, 0.04–0.57, p=0.005)), but surprisingly had fewer painful crises (28 v. 46 % (0.5, 0.03–0.9, p=0.03)).

Conclusions

HbSS women had a 10-fold excess of maternal near-misses. Additional research may further clarify the effects of aspirin on pregnancy outcomes as related to SCD genotypes.
Non-integrated conditionals as speech-event modifiers: evidence from Romance
Authors: Munaro Nicola

Capitalizing on the basic distinction between central and peripheral adverbial clauses, the main aim of this contribution is to shed some light on certain left-right asymmetries in the distributional properties of integrated and non-integrated (concessive) conditional clauses in standard Italian, drawing indirect evidence from multiple complementizer constructions in (early) Romance. By exploring the distribution of preposed central conditional clauses in multiple complementizer constructions in some early Italo-Romance varieties and in modern Ibero-Romance, I argue, following previous analyses, that this kind of adverbial clauses occupy a topic-related specifier position within the left periphery of embedded clauses; similarly, in modern Italian and in some Italo-Romance varieties, central (concessive) conditional clauses may undergo fronting to the specifier of a functional projection situated within the higher Topic field, but crucially below the Force node. I claim that, unlike central conditionals, non-integrated addressee-oriented conditional clauses should be analyzed as sentential speech event modifiers generated within the specifier of a speech-act related projection in the left-periphery above the Force node of the main clause, which accounts for their peculiar distributional properties.
Insight on the properties of multi-walled carbon nanotubes reinforced nitrile rubber composites cured by ionizing radiation or peroxide: a comparative study
Authors: El-Nemr Khaled F. , Radi Hamdi , Khalaf Aman I. , Hamdy Eman M.
Published: April 2024

A comparative study was carried out between ionizing radiation and dicumyl peroxide (Dicup) as two different curing systems for nitrile rubber (NBR) reinforced with different concentrations of multi-walled carbon nanotubes (MWCNTs). Upon ionizing irradiation, the tensile strength (TS) of the composites increases with increasing absorbed dose up to 50 kGy and then decreases with increasing absorbed dose. TS also increases with increasing of MWCNTs content up to 0.75 phr (part per hundred part of rubber). TS values are decreased in the case of Dicup curing as compared with radiation curing. Other characterizations were made, such as the Differential Scanning Calorimeter (DSC), Fourier transform infrared spectroscopies (FTIR), and morphological characterization, which give further implications for the good compatibility between MWCNTs and NBR phases. A study of the effect of fuel on NBR/MWCNTs composites showed that the composites cured by Dicup had lower values for swelling in fuels when compared with others that were cured by radiation.

Published: April 2024

Iron oxide nanoparticles have found wide applications in different fields of biomedicine and advanced catalytic applications. Several studies have suggested using iron oxide nanoparticle (Fe2O3-NPs) be a potential candidate for antibacterial activity assessment. Iron oxide nanoparticles, apart from being available extensively and cheap, also plays a vital part in multiple biological processes, making it an interesting choice of selection. The aim of the present study revolves around synthesis and characterization of iron oxide Fe2O3-NPs, followed by assessment of its antimicrobial activities and its catalytic behaviour. Synthesis of Fe2O3-NPs was performed by co-precipitation approach, and commercial iron oxide samples were studied for the comparison. The silver nanoparticles were also doped to the iron oxide nanoparticles and studied for the synergic effect. The samples characterization was done by UV-visible, X-ray diffraction (XRD), Scanning electron microscopy (SEM) with EDS and transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), Raman Spectroscopy (RAMAN). Antimicrobial activity was checked by agar diffusion assay against Gram positive and Gram negative bacteria. The electrode performance of the iron oxide samples was done by cyclic voltammetry to explore their application in the energy storage and sensor.
The Work of Citrus
Authors: Freese Lauren M.
Published: April 2024

American artist Elsie Lower Pomeroy’s career can be considered in two phases: her precise scientific watercolors of fruit varietals for the United States Department of Agriculture (USDA) and her extensive body of work featuring California life, landscape, and agriculture. A strong interest in agriculture and nature persisted throughout Pomeroy’s varied career and led to her series of five watercolor paintings of the Southern California citrus industry, completed in 1937. Pomeroy leveraged rhythmic abstraction and her knowledge of citriculture to bridge art and agriculture. The series contrasts the dangers of industrial orange cultivation with the economic and culinary upside, especially for the wealthy growers who profited from the labor depicted. Furthermore, while the series incorporates skills and knowledge from the artist’s USDA training, it represents a clear departure from pomological illustration, a genre closely associated with women, in favor of genre scenes that feature revealing portrayals of the danger of industrial citrus.
“Turn Back the Noisy Wheels of Progress”
Authors: Lorimer Michelle
Published: April 2024

The interests of Euro-American people who supported assimilation campaigns and participated in heritage tourism converged in Southern California in the early 1900s. The visual culture illustrated in postcards created an alternative sense of place. It was based in Native exploitation that promoted modernization and celebrated assimilation programs. Local promoters, tourists, and new residents displaced Indigenous people from active roles in the cultural heritage. Promoters and tourists used sites imbued with Native life, such as the Sherman Institute and the California missions, to popularize romanticized histories of the region. While intended to be visually pleasing, postcards from Southern California in the late 1800s and early 1900s represented a socially constructed history that ignored the realities of these contested sites. Using appeals to nostalgia to frame superficial narratives of vanishing Native American cultures, boosters created a market for collectors that capitalized on cultural tourism. Together, this visual culture and the physical landscape of many of Southern California’s tourist sites attempted to publicize the success of Native assimilation. This visual culture highlighted the climate of the time, when writers and promoters applauded progress toward Americanization and brought those views to wide audiences.
Biden’s CHIPS and Science Act in Historical Perspective
Authors: Estruth Jeannette Alden
Published: April 2024

In August 2022, the CHIPS Act made headlines across the country with its monumental subsidy numbers and dizzying policy provisions. But what does CHIPS mean in historical context? And in particular, what does the act mean for California, and what does California’s past tell us about CHIPS’s future? This article introduces the reader to recent technology policy history, and writes into the present moment to place the act’s elements in context and explain how it may shape public investment, climate legislation, wealth inequality, foreign policy, the jobs economy, the environment, military spending, and even a Green New Deal.
Mahler’s Contralto Voice
Authors: Kramer Lawrence
Published: April 2024

Mahler’s use of the contralto voice in his Second and Third Symphonies and in Das Lied von der Erde is commonly observed but little examined. The contralto sound in the “Urlicht” movement of the Second Symphony and the “Midnight Song” of the Third remains to be thought through; so does the return of the contralto a decade later in Das Lied. Why this voice? What expressive and cultural force does it bear? And why does Mahler in the Third Symphony and again in Das Lied explicitly assign a female voice to a male narrator? The starting point for answers to these questions is the unique status of the contralto voice in Mahler’s musical world. Between roughly the 1820s and the 1920s, this rarest of all voice types enjoyed a transcendental mystique. Traces of its elevation, linked to its rarity, persist into the present, as does the descriptive language that the voice attracts. The transcendental character of the contralto, however, did not lead from the earth but to it. This is the case even in the “Urlicht” movement, which might seem to go the other way. And “lead” is a key term: the voice belongs to an unforeseen guide who leads the listener to a more acute sense of earthly existence. Mahler’s model here was almost surely the contralto role of Erda—a guide who loses her own way—in Wagner’s Ring cycle. But Mahler changes the contralto’s gender, or, more exactly, makes the contralto guide a hybrid being who belongs to no gender, much like the angels in Rainer Maria Rilke’s near-contemporaneous Duino Elegies of 1912–22.
Mahler Making Love: Mengelberg’s Adagietto
Authors: McClary Susan
Published: April 2024

We are accustomed to hearing the Adagietto from Mahler’s Fifth Symphony played as an elegy, appropriate for state funerals and the like. But Wilhelm Mengelberg, once Mahler’s assistant, claimed that the movement was composed as a love letter to Alma, and his performance offers an almost-too-explicit scenario of love making. In this article, I will return to Mengelberg’s argument for this interpretation, then examine the ways his performance decisions produce simulations of erotic interactions. But his reading raises questions concerning historical performance practices: how prevalent were Mengelberg’s tempo fluctuations and portamenti in the early twentieth century? To what extent should these practices inform our readings of other repertories of the time? And why might later conductors have chosen the elegaic mode, despite the fact that they thereby obscure what might be an important trace of Mahler’s erotic sensibilities?

Published: April 2024

Bis vor Kurzem war die Begebung elektronischer Aktien in Deutschland nicht möglich. Durch die Verabschiedung des Gesetzes zur Finanzierung von zukunftssichernden Investitionen (Zukunftsfinanzierungsgesetz – ZuFinG) hat sich dies geändert. Dieses sieht die Möglichkeit vor, elektronische Aktien (eAktien) zu begeben. Damit ist ein großer Schritt in Richtung Digitalisierung des Kapitalmarktes in Deutschland getan. Im Detail werfen die neuen Regelungen zur eAktie aber dennoch Fragen auf.

Der vorliegende Beitrag beschreibt den Weg von der „klassischen“ verbrieften Aktie zur nunmehr funktionell verbrieften, elektronischen Aktie und ordnet die eAktie in das bestehende aktienrechtliche und wertpapierrechtliche System ein. Sodann beleuchtet der Beitrag die Möglichkeiten der Übertragung und Verfügung über die eAktie aus rechtlicher und praktischer Perspektive, bevor abschließend ein Exkurs zum viel beachteten Verbot der Krypto-Inhaberaktie erfolgt.

Objectives: The present study aims to study the prevalence and association of anemia with random blood glucose levels and other anthropometric indices in a sample of young female students from the University of Hail (UOH) in Hail City, KSA. Methodology: A sample of 400 female college students was enrolled and body composition was measured by using the bioelectrical impendence technique. Random blood glucose levels (RCBG) were measured using One Touch® Ultra® (Lifescan Johnson & Johnson, Milpitas, USA). The study population was divided into two RCBG groups: low RCBG group (<110 mg/dl) and high RCBG group (>110 mg/dl) and Hb: normal Hb group (> 12 g/dl) and anemic group (<12 mg/dl). Pearson correlation, chi-square analysis, and linear regression analysis were used to examine associations between variables. T-test was used to check to mean differences. Results: Around 79 percent of the study population were having low RCBG (<110 mg/dl) while 21 percent were observed to have high RCBG (>110 mg/dl). Around 69 percent of the study population were having normal Hb levels while 31 percent were observed to have anemia as defined by low Hb levels. T–test results indicate that there are significant differences in mean values for all studied anthropometric variables, RCBG with HB groups. The mean RCBG value was significantly higher for the anemia group as compared to the Normal Hb group. Pearson correlation indicated the associations for Hb were positive and highly significant for studied anthropometric variables while the relationship with RCBG was significantly negative. Odd’s ratio indicated that there is a higher risk of 1.8 times for the anemic group to have high RCBG as compared to the normal Hb group. In linear regression analysis, for RCBG values, Hb and Haemaetocrit explained 14.1 % of the variance; while Hb, Haemaetocrit, and Visceral fat together explained 15.7 % of the variance. Conclusion: In the present study, Hemoglobin and hematocrit were identified as useful tools in predicting risk for diabetes even in the young Saudi female population. Diabetes and anemia relationship could be casual. However, future studies with larger sample sizes are required to obtain more conclusive results.
