EARLY EUROPEAN WOMEN IN SEISMOLOGY
Authors: BUFORN ELISA 
Published: May 2024

ABSTRACT
Inge Lehmann is the best-known European woman seismologist, but she is not an isolated case. The presence of women seismologists in Europe has a long tradition, with the earliest women researchers appearing at the beginning of the 20th century in the United Kingdom, Denmark, the former USSR, and France. After World War II, women seismologists in Europe had an important presence. Their names are present in the lists of participants in seismological international meetings (IASPEI or ESC), where information about these women and their roles in these institutions can be found. This paper concentrates on the presence of women seismologists in Europe in the 1920–1970 period. After the 1970s, the number of women in seismology has increased considerably.
MINING PENCILS, SCULPTING GRAPHITE: THE SIBERIAN EXPEDITION OF J.-P. ALIBERT (1844–1857) AND THE EVOLVING 19TH CENTURY EUROPEAN VISUAL AND MATERIAL CULTURE RELATED TO EARTH SCIENCES
Authors: NAPOLITANI MADDALENA 
Published: May 2024

ABSTRACT
This article explores, through a case study of Jean–Pierre Alibert's (1820–1905) expedition in Siberia (1844–1857), the relationship established between Earth sciences, mining, and visual arts during the second half of the 19th century. Alibert was a French businessman who discovered an important deposit of graphite in Siberia. He then built a mine to exploit this material which was in high demand to produce pencils. When Alibert returned to Europe in 1857, he created an album of gouaches to commemorate his expedition, and he offered some sculptures composed of graphite and nephrite jade to important scientific institutions in Paris as trophies of the expedition. While a few written sources are available, I will directly question these visual and material sources to situate this case study within the context of its time, and of Earth sciences’ progress and technical achievements, to shed light on the phenomena that characterized the quest for a renewed scientific visual language related to Earth sciences.
ARTURO ISSEL (1842–1922): THE MAN FROM GENOA BEHIND THE TYRRHENIAN STAGE OF THE PLEISTOCENE
Authors: HISTON KATHLEEN 
Published: May 2024

ABSTRACT
Arturo Issel (1842–1922) introduced the regional Tyrrhenian stage of the late Pleistocene in 1914. This still stands within modern stratigraphic classification as an Italian Marine Stage for the Mediterranean Sea marking the base of the Late Pleistocene underlining the scientific importance of Issel's research within the geological sciences. This paper provides a short overview of the career and the wide-ranging interests of this Italian geologist and naturalistic traveller in order to provide a context to the knowledge and research experience behind his stratigraphic work. As university professor in Genovese society during the late nineteenth and early twentieth centuries, he played an important role in scientific instruction, exploration and research contributing to the popularization of science through museum collections and publications and in the application of such knowledge within public office both in Liguria and within Italy. He formed part of the Italian delegation at International Geological Congresses and held membership of the most outstanding geological societies and scientific academies of the time.

Published: May 2024

This essay discusses how productions of Shakespeare’s plays that transcend various geographical, national, and linguistic boundaries have influenced the theatrical-political discourse in East-Central Europe in the twenty-first century. It focuses primarily on the work of four internationally-established directors: Andrei Şerban (Romania), Jan Klata (Poland), David Jařab (Czech Republic), and Matei Vișniec (Romania), whose works have facilitated interregional cultural exchange, promoting artistic innovation and experimentation in the region and beyond. Among the boundary-crossing productions analysed in detail are Vișniec’s Richard III will not Take Place, Jařab’s Macbeth – Too Much Blood, Klata’s Measure for Measure, and Serban’s Richard III. The essay also notes that while there has been a relative scarcity of Shakespearean productions in this region engaging closely with gender and race inequalities, productions such as Klata’s African Tales or Vladimír Morávek’s Othello manage to work with these politically charged topics in subtler but still productive ways. The essay concludes that the region’s shared historical experience of totalitarian regimes followed by the struggles of nascent democracies, provides a fertile ground for a diverse and internationally ambitious Shakespearean theatre.

Published: May 2024

This collectively authored position paper discusses “hybrid” Shakespeares in Central and Eastern Europe, focusing on productions that offer formal experimentation and transnational perspectives. While their contexts remain regional, they provide an insight into how Shakspeare has been mobilised regionally. The paper consists of four distinct parts, each considering Shakespeare in a hybrid form: in opera, dance and musical theatre as well as puppetry in the transnational, regional context. The general discussions of Shakespeare’s presence/appropriation in these art forms are followed by case studies that illustrate the significance of hybridity that characterises Shakespeare in the Central and Eastern European transnational context. Our brief analyses and selected case studies suggest a need for a detailed study of Shakespeare and performative arts in Central and Eastern Europe that would concentrate on the transgressive impulse these theatrical blends realised through formal experiment and artistic innovation.

Major Traffic Safety Reform and Road Traffic Injuries Among Low-Income New York Residents, 2009–2021
Authors: Dragan Kacie L. , Glied Sherry A. 
Published: May 2024

Objectives. To evaluate the effects of a comprehensive traffic safety policy—New York City’s (NYC’s) 2014 Vision Zero—on the health of Medicaid enrollees. Methods. We conducted difference-in-differences analyses using individual-level New York Medicaid data to measure traffic injuries and expenditures from 2009 to 2021, comparing NYC to surrounding counties without traffic reforms (n = 65 585 568 person-years). Results. After Vision Zero, injury rates among NYC Medicaid enrollees diverged from those of surrounding counties, with a net impact of 77.5 fewer injuries per 100 000 person-years annually (95% confidence interval = −97.4, −57.6). We observed marked reductions in severe injuries (brain injury, hospitalizations) and savings of $90.8 million in Medicaid expenditures over the first 5 years. Effects were largest among Black residents. Impacts were reversed during the COVID-19 period. Conclusions. Vision Zero resulted in substantial protection for socioeconomically disadvantaged populations known to face heightened risk of injury, but the policy’s effectiveness decreased during the pandemic period. Public Health Implications. Many cities have recently launched Vision Zero policies and others plan to do so. This research adds to the evidence on how and in what circumstances comprehensive traffic policies protect public health.

Published: May 2024

Summary
PT PHR as a leading energy company has a vision to become a world-class energy company. The BNG field is part of the area of work of PT PHR Zone 4 whose main production is natural gas and the plan is to be commercialized as a sale of gas. The gas produced from the BNG field has a CO2 content of 18% so it does not meet the specification of the limit set in the Agreement for the Sale of Gas between the PHR and the Consumer which amounts to 8% CO2 contents so that the gas from BNG fields are blending with gas from the MSB fields which have a low CO2 concentration to be further distributed to consumers mixing gas from both such fields has a content of CO2 at a figure of 4-6% that is still below the limit Gas sale and purchase requirements (PJBG), the problem will occur in 2027 where the production of gas of BNG field will increase, while the forecast of deliverable gas field MSB is expected to decrease to 50% from 2024 so the content of the gas mixing will exceed the limit. (PJBG). To meet the requirement of sale, a study in the selection of CO2 Removal Technology Unit is required to be installed to complete the Production Facility in the BNG field area. The author uses methodologies empirically and according to the field conditions to effective research goals. The writer uses a conceptual study framework. Quantitative data is obtained from data within the company, while qualitative data comes from discussions with the team and based on journals or studies that have been previously compiled. In addition, data from some kind of literature is also used in analysing the selection of gas-sweetening technologies. All necessary information and data are further analyzed in accordance with the conceptual framework. To ensure that the recommended operations management strategy is carried out through technical analysis, a study of mathematical models is conducted using some tested business strategy tools.

Published: May 2024

Abstract

The squid, Sepioteuthis lessoniana, is a remarkable fishery product which is exported by many nations for use in industrial production or human consumption. This study focused on the synthesis of silver nanoparticles (AgNPs) from squid ink (SI) and its wide range of applications. The formation of the nanoparticles was confirmed through UV-Visible spectroscopy, FT-IR, XRD, SEM with EDAX, DLS, and Zeta potential analysis. The results showed a strong absorbance peak at 407nm, the presence of various functional groups, a nanocrystalline structure with a crystalline size of 17.56 nm, spherical shaped particles with an average size of 76 nm, and the presence of the highest % mass of Ag and uniformly dispersed particles, respectively. The bioactivity of the synthesized squid ink silver nanoparticles was analyzed through antibacterial, antioxidant, anticancer, and toxicity studies. The dye degradation assay was also analyzed as a means of wastewater treatment for different industrial dyes. The antibacterial activity showed the highest zone of inhibition of 24mm at a concentration of 100 µg/ml against Escherichia coli, followed by other tested strains. The nitric oxide radical scavenging assay showed the highest antioxidant activity (92%) at a concentration of 100µg/ml. The cytotoxic ability of SI-AgNPs against the MDA-MB-231 breast cancer cell line revealed an IC50 value of 4.52 µg/ml. Toxicity study revealed a dose and time-dependent activity with the LC50 value of 5.090 and 3.303 mg/ml for 24 and 48 hours, respectively. The successful degradation of dyes by SI-AgNPs is attributed to the cooperative action of the electron relay system with Ag as a catalyst and SI as a catalytic support. These findings indicate that SI-AgNPs is a novel potential product that should be further studied to improve its pharmacological, biomedical, and environmental applications.
A semi-analytical and numerical approach for solving 2-D and 6-D nonlinear and complex functionally graded tubular systems
Authors: Dai Liming , Foroutan Kamran 
Published: May 2024

Abstract

This study delves into nonlinear vibratory responses of functionally graded (FG) tubes subjected to transverse loads, considering material properties that vary with temperature. A refined beam model established for the tubes satisfies the stress boundary conditions on inner and outer surfaces of the tubes. The nonlinear vibration equations for these functionally graded tubes are meticulously derived with employment of the Zhang–Fu high-order shear deformation beam model, the von Kármán equation, and Hamilton’s principle. The proposed approach is applied to address externally excited nonlinear FG tube systems, encompassing both the 2 degrees of freedom (DOF) single-mode systems and 6 DOF multi-mode systems. Utilizing Galerkin’s method, the resulting discretized nonlinear governing equations allow for the analyses of single and multi-mode tubular system behavior. In solving for the tubular system, an approach implementing the P-T method is managed to be implemented, which yields a continuous semi-analytical solution throughout the entire time domain considered. The approach also demonstrates the advances on the development of a genuinely new computational method with broad impact. In comparison to the widely used Runge-Kutta (R-K) method, the proposed approach demonstrates superior efficiency, accuracy, and reliability, especially for highly nonlinear and complex systems like the FG tubular systems.

Published: May 2024

Abstract

Background
Little guidance exists on best practices for implementing and sustaining wastewater-based surveillance (WBS) for SARS-CoV-2 in carceral settings. To ensure alignment with priorities of stakeholders, we aimed to understand the perspectives of persons with lived experience (PLE) of jail who were incarcerated during the height of the COVID-19 pandemic on infection control.
Methods
We recruited two PLE at each of four jails: Cook County (IL), Fulton County (GA), Middlesex County (MA), and Washington DC. Focus Group Discussion (FGD) guides followed the Consolidated Framework for Implementation Research (CFIR). Two FGDs focusing on lived experience with jail infection control protocol and WBS were conducted, and six Key Informant (KI) interviews followed to gain insights on communicating WBS results. We used a combination of deductive thematic analysis based on CFIR constructs and inductive analysis to capture emergent themes.
Results
Themes from FGDs included: (1) variable experiences with COVID-19 infection control protocols including intake processes, individual testing, isolation and quarantine, (2) the perceived attitudes of fellow residents and staff surrounding COVID-19 mitigation in a carceral setting; and (3) perceived benefits and challenges involving WBS implementation and messaging. KIs emphasized 1) The importance of straightforward health messaging and trustworthiness in the communication of WBS results, 2) Support for enhanced health education around outbreaks, and 3) Receptiveness to WBS being used as a tool to measure common infectious agents (i.e., influenza) but hesitancy regarding its application to conditions such as HIV and illicit drug use. PLE articulated support of robust infection control programs and receptiveness to expanding WBS if conducted in a non-stigmatizing manner.
Conclusion
Perspectives from PLE can help shape the infection control programs for future outbreaks and inform the expansion of WBS implementation in carceral facilities. It will be important to consider the voices of current and former residents, as receivers of care, to promote an environment conducive to comprehensive infection control. In addition to having infection control programs consistently execute set protocols and educate all stakeholders, PLE identified collaboration between jail staff and residents, and clear communication around program expectations as priorities. Findings from this qualitative study can be shared with jail decision makers and the perceived engagement of stakeholders can be measured.
