What’s another year? The lengthening training and career paths of scientists
Authors: Cheng Stephanie D.
Published: May 2023

Lengthening doctorate and post-doctorate training allow science, technology, engineering, and mathematics (STEM) Ph.Ds. to persist in high-intensity academic research environments at the cost of significant lifetime earnings. Using the largest longitudinal survey of U.S. Ph.D. recipients, I construct career paths for 135,599 STEM research doctorate holders over six job types and two employment statuses. Examining Ph.D. cohorts in four major STEM fields from 1950 to the present, I find evidence that the increasingly prevalent postdoctoral position allow STEM Ph.Ds. to remain in high-intensity academic research positions, albeit not necessarily on the tenure-track. However, these research opportunities come with an approximately $3,700 deduction in annual earnings per postdoctoral year. Taken together, STEM Ph.Ds. must weigh the non-pecuniary costs of remaining in academic research with this earnings loss to determine if postdoctoral positions are a worthwhile investment.
Evaluation of health care professionals’ knowledge, attitudes, practices and barriers to pharmacovigilance and adverse drug reaction reporting: A cross-sectional multicentral study
Authors: Khan Zakir , Karatas Yusuf , Hamid Syed Muhammad
Published: May 2023

Background

Healthcare professionals’ involvement and reporting of adverse drug reactions are essential for the success of a pharmacovigilance program. The aim of this study was to assess healthcare professionals (medical doctors, pharmacists, nurses, dentists, midwives, and paramedics) current knowledge, attitude, practices, and barriers regarding pharmacovigilance and adverse drug reactions reporting in multicentral healthcare settings.

Methods

A cross-sectional face-to-face survey was conducted among currently working healthcare professionals in various hospitals in ten districts of Adana province, Türkiye from March to October 2022. A self-administered, pretested questionnaire (Cronbach’s alpha = 0.894 for knowledge, attitudes and practices variables) was used for data collection. The questionnaire’s final draft included five sections (sociodemographic/general information, knowledge, attitude, practices, and barriers) with 58 questions. The collected data was analyzed in SPSS (version 25) using descriptive statistics, the chi-square test, and logistic regression.

Results

Of the total 435 distributed questionnaires, 412 completed the entire questionnaire, yielding a 94% response rate. The majority of healthcare professionals (60.4%; n = 249) had never received pharmacovigilance training. Among healthcare professionals 51.9% (n = 214), 71.1% (n = 293) and 92.5% (n = 381) had poor knowledge, positive attitudes and poor practices, respectively. Only 32.5% of healthcare professionals kept the record of an adverse drug reaction and only 13.1% reported adverse drug reactions. The profession (medical doctors, pharmacists, nurses, dentists, midwives, and paramedics) of healthcare professionals and a lack of training were predictors of poor adverse drug reaction reporting (p < 0.05). A statistically significant difference in healthcare professionals and knowledge, attitude and practices scores was also observed (p < 0.05). The main barriers which were supposed to discourage adverse drug reactions reporting by the healthcare professionals were higher workload (63.8%) followed by thinking that a single adverse drug reaction report makes no impact (63.6%) and lack of a professional atmosphere (51.9%).

Conclusion

In the current study, most healthcare professionals had poor knowledge and practice, but they had a positive attitude toward pharmacovigilance and adverse drug reactions reporting. Barriers to under-reporting of adverse drug reactions were also highlighted. Periodic training programs, educational interventions, systematic follow-up of healthcare professionals by local healthcare authorities, interprofessional links between all healthcare professionals, and the implementation of mandatory reporting policies are critical for improving healthcare professionals knowledge, practices, patient safety and pharmacovigilance activities.
Primary and reproductive healthcare access and use among reproductive aged women and female family planning patients in 3 states
Authors: Fuentes Liza , Douglas-Hall Ayana , Geddes Christina E. , Kavanaugh Megan L.
Published: May 2023

Public funding plays a key role in reducing cost barriers to sexual and reproductive health (SRH) care in the United States. In this analysis, we examine sociodemographic and healthcare seeking profiles of individuals in three states where public funding for health services has recently changed: Arizona, Iowa, and Wisconsin. In addition, we examine associations between individuals’ health insurance status and whether they experienced delays or had trouble in obtaining their preferred contraception. This descriptive study draws on data collected between 2018 to 2021 in two distinct cross-sectional surveys in each state, one among a representative sample of female residents aged 18–44 and the other among a representative sample of female patients ages eighteen and older seeking family planning services at healthcare sites that receive public funding to deliver this care. The majority of reproductive-aged women and female family planning patients across states reported having a personal healthcare provider, had received at least one SRH service in the preceding 12 months, and were using a method of birth control. Between 49–81% across groups reported receiving recent person-centered contraceptive care. At least one-fifth of each group reported wanting healthcare in the past year but not getting it, and between 10–19% reported a delay or trouble getting birth control in the past 12 months. Common reasons for these outcomes involved cost and insurance-related issues, as well as logistical ones. Among all populations except Wisconsin family planning clinic patients, those with no health insurance had greater odds of being delayed or having trouble getting desired birth control in the past 12 months than those with health insurance. These data serve as a baseline to monitor access and use of SRH services in Arizona, Wisconsin, Iowa in the wake of drastic family planning funding shifts that changed the availability and capacity of the family planning service infrastructure across the country. Continuing to monitor these SRH metrics is critical to understand the potential effect of current political shifts.
Parental supervision positively impacts children’s economic prospects two decades later: A prospective longitudinal study
Authors: McGinnis Ellen W. , Halvorson-Phelan Julia , Shanahan Lilly , Guangyu Tong , Copeland William
Published: May 2023

Importance

Upward income mobility is associated with better health outcomes and reduced stress. However, opportunities are unequally distributed, particularly so for those in rural communities and whose family have lower educational attainment.

Objective

To test the impact of parental supervision on their children’s income two decades later adjusting for parental economic and educational status.

Design

This study is a longitudinal, representative cohort study. From 1993–2000, annual assessments of 1,420 children were completed until age 16, then followed up at age 35, 2018–2021, for further assessment. Models tested direct effects of parental supervision on child income, and indirect effects via child educational attainment.

Setting

This study is an ongoing longitudinal population-based study of families in 11 predominately rural counties of the Southeastern U.S.

Participants

About 8% of the residents and sample are African American and fewer than 1% are Hispanic. American Indians make up 4% of the population in study but were oversampled to make up 25% of the sample. 49% of the 1,420 participants are female.

Main outcomes and measures

1258 children and parents were assessed for sex, race/ethnicity, household income, parent educational attainment, family structure, child behavioral problems, and parental supervision. The children were followed up at age 35 to assess their household income and educational attainment.

Results

Parental educational attainment, income, and family structure were strongly associated with their children’s household income at age 35 (e.g., r = .392, p < .05). Parental supervision of the child was associated with increased household income for the child at age 35, adjusting for SES of the family of origin. Children of parents who did not engage in adequate supervision earned approximately $14,000 less/year (i.e., ~13% of the sample’s median household income) than those who did. The association of parental supervision and child income at 35 was mediated by the child’s educational attainment.

Conclusion and relevance

This study suggests adequate parental supervision during early adolescence is associated with children’s economic prospects two decades later, in part by improving their educational prospects. This is particularly important in areas such as rural Southeast U.S.
‘Insider news’ on Russian Telegram: Resembling truth, proximity and objectivity
Authors: Belinskaya Yulia
Published: May 2023

This article explores a new style of journalism identified in the contents of 21 public Telegram channels from the second half of 2020. The case follows the poisoning of the Russian oppositionist Alexei Navalny as part of a broader research programme on the Russian public sphere. The qualitative analysis of the data provides insight into the use of Telegram as a source for ‘insider news’. This article distinguishes the linguistic peculiarities of the texts, such as markers of orality, and contrasts them with various modes of virtual journalism. The article proposes a model of a three-way proximity-building as a feature of a new journalism style. The article contributes to understanding the dynamics of the Russian public sphere and its overspill beyond the Russian territory and the institutional media outlets.
The Independent Press Standards Organisation and accuracy: A comparative study of complaints-handling procedures in four UK newspapers
Authors: Dagoula Chrysi , Katsirea Irini , Harrison Jackie
Published: May 2023

This study examines the attitudes of four Independent Press Standards Organisation (IPSO)-regulated UK newspapers towards redressing inaccuracies in their print editions. It analyses the ways in which the Daily Mail, the Daily Telegraph, The Times and The Sun dealt with complaints in order to assess their attitudes towards the editorial standard of accuracy. Further, this study aims to evaluate IPSO’s impact on the newspapers’ complaints-handling processes throughout 2016, more than a year after its establishment, at a time when its regulatory arsenal had been consolidated and put into practice. We found that there was no evidence of any binary opposition in a spectrum of quality/popular press reflected in the sample newspapers’ respective attitudes and responses toward IPSO’s complaints-handling standards on matters of inaccuracy. Furthermore, our evaluation of the position, timing and wording of the published corrections of all four newspapers did not confirm a marked difference in the extent to which they were prepared to demonstrate their accountability to their readers by drawing published inaccuracies to their attention. IPSO has contributed to more systematic complaints handling but more needs to be done. Our findings are of wider relevance beyond the specific period under investigation.

Isak Dinesen’s weird voodoo novel
Authors: Mortensen Peter
Published: May 2023

With its awkward generic shifts, odd repetitions, confusing spatial dislocations, unstable characters and inconclusive supernatural horrors, I here argue, bilingual Danish author Isak Dinesen’s The Angelic Avengers weirds our experience of living in a familiar, predictable and rule-governed universe. In my analysis, I especially foreground Dinesen’s use of West Indian voodoo, which is a prominent weirding device largely overlooked by the novel’s relatively few critics. Dinesen, I argue, wrote her novel amidst a widespread international voodoo and zombie vogue, tapping into popular representations of Caribbean witchcraft in nonfiction, pulp fiction and film. In The Angelic Avengers, I argue, Dinesen appropriates voodoo themes and characters, to conjure the presence of ominous agencies that trouble enlightened reason’s ability to explain and master the world.
Epidemic of affect: Contagious anxiety and cinematic metaphor in She Dies Tomorrow (2020)
Authors: Kirby Jennifer
Published: May 2023

Although written before the COVID-19 pandemic, Amy Seimetz’s She Dies Tomorrow is widely regarded as speaking to collective social anxiety. In the film, Amy is convinced that she will die the next day. She tells her friend, Jane, who becomes convinced that she too will die. Everyone that Jane tells catches the conviction and it spreads like a virus. This article offers an alternative reading, analysing the film as a meditation on (horror) cinema as a vehicle for affective bodily contagion. Filmic images and sounds are intangible and do not physically touch viewers yet can nevertheless carry affect that makes bodies respond to and sometimes replicate what is shown on screen. Similarly, in She Dies Tomorrow, an intangible idea causes affective response and mimesis, as well as audio-visual hallucinations. The article explores how contagious anxiety might be spread through cinematic objects, drawing from affect, phenomenology and object-oriented ontology (OOO). Finally, it explores the film’s engagement with both Derrida’s spectrality of cinema and the nature of the horror genre.
The horrors of capitalism in Reza Abdoh’s The Law of Remains (1991)
Authors: Hann Louisa
Published: May 2023

Reza Abdoh’s The Law of Remains (1991) is a play replete with violence, cruelty, murder and gore. While many critics view the playwright’s horror-inflected plays as reflective of an Artaudian philosophy that attempts to uncover the essential human ‘truth’ underlying societal ills, I view The Law of Remains as an exercise in dialectical horror. That is, a play that harnesses the grammar of gore and excess to critique capitalism’s disempowering and rapacious qualities while highlighting how consciousness of such qualities could galvanize positive opposition to oppression. In this article, I examine some of the play’s key moments of horror through a Marxist lens to uncover an anti-capitalist structure of feeling that lay in stark opposition to dominant neo-liberal forces in the early 1990s.
Arc analysis: Redefining character arcs for ‘constant’ characters
Authors: Mullins Anthony
Published: May 2023

A frequent assumption made in Anglo-American screenwriting manuals asserts that in most, if not all, ‘successful’ screen stories, the protagonist goes through a significant emotional transformation, sometimes referred to as a ‘character arc’. However, many classic, highly profitable and critically acclaimed feature films centre on protagonists who are emotionally ‘constant’, in that they do not appear to emotionally transform. As a result, these otherwise successful narratives have either been omitted from analysis or their analysis has been distorted to fit the orthodox yet vaguely defined understanding of a character arc. In this article, I will outline a new model of character arcs called ‘Arc Analysis’ that, by taking account of both the ‘internal’ and ‘external’ worlds of the protagonist, has the capacity to accurately describe the arcs of emotionally ‘constant’ characters. I will demonstrate the Arc Analysis model using an analysis of Jaws (1975), a highly successful film that, I will argue, features a protagonist who does not emotionally transform and, as a result, is frequently misinterpreted. Furthermore, I will, using the key components of Arc Analysis, propose a new and more precise definition of a character arc.

O potencial do turismo se baseia nos recursos naturais e culturais incorporados à localidade. No entanto, o papel do turismo no desenvolvimento local ainda não atingiu o potencial máximo. Os principais desafios são maior assertividade do governo local, melhorias de infraestrutura e serviços, colaboração entre os atores e a participação social. A pesquisa destaca a importância do turismo para a diversificação da economia rural e orienta os gestores e instituições com propostas voltadas para impulsionar a revitalização do meio rural.
The adverse psychological impacts of digital technology: critiquing Schulman’s this beautiful life from postmodern insights
Authors: Adhikary Ramesh Prasad
Published: May 2023

This study aims to examine the psychological effects of digital technology on individuals by analyzing the characters of Jake and Daisy in This Beautiful Life. It also focuses on how the postmodern trend of imbibing the ethos and spirit of late capitalist consumer culture and the commodification of subjectivity put extreme pressure on individuals, leading to their disintegration and degeneration. The study uses the theoretical ideas and insights of leading postmodern theorists, such as Arthur Kroke and David Kroke, to analyze the harmful effects of the postmodern trend of simulating double identity in excess. It explores the causes of the psychic deviations and disintegration of Jake and Daisy within the postmodern context. This research is a qualitative analysis of the novel by using a postmodern theoretical framework to analyze the characters of Jake and Daisy and their actions and choices in the novel. The study finds that the harsh psychological effects of digital technology are evident in the characters of Jake and Daisy. Their unrestrained involvement in the postmodern trend of imbibing the ethos and spirit of late capitalist consumer culture leads to the degeneration and decadence of their psychic integrity. Meanwhile, Daisy's mundane and monotonous life leads her to construct fantasies in her mind, leading her to embark on a sporadic spree of murdering her close friends. The study concludes that the postmodern trend of imbibing the ethos and spirit of late capitalist consumer culture and the commodification of subjectivity have a detrimental effect on individuals' psychological well-being. The lack of postmodern trend to erase the boundary between the normal and the abnormal exacerbates the situation, leading individuals to become cruel and violent.
Assessment of the water quality of Bar-Bula Village well waters, Tafawa Balewa local government area, Bauchi State, Nigeria
Authors: Ogham Chidi J. , Dabak Jonathan D. , Jaryum Kiri H.
Published: May 2023

There was a report of health challenges in our study area due to the consumption of water from wells sited in the community. The research was aimed at assessing the water quality parameters of the wells consumed by the villagers towards providing information on the possible health implication(s) of its consumption. Two sampling sites were selected, well 1 and well 2, which were hitherto the sole sources of water in the village. Physicochemical and microbiological quality parameters of samples were done in order to assess their conformance with the specification of Nigerian Standard for drinking water quality (NIS 554-2015). The results indicated that all physical water quality parameters have their mean concentration values below the maximum permissible limits, except colour which had total mean concentrations of 16.5 ± 0.65 TCU and 15.3 ± 0.65 TCU for well 1 and well 2 respectively, are relatively above the allowable unit range of 15 TCU (NIS-554-2015). The water quality assessment of wells also revealed high concentration of Cadmium (0.11 mg L-1 and 0.16 mg L-1, for well 1 and 2 respectively as against 0.003 mg L-1 specified by standard) and Magnesium (185 mg L-1 and 105 mg L-1 for well 1 and 2 respectively as against the maximum permissible limit of 20 mg L-1 specified by the standard). The microbial values of samples fall below the maximum permissible limit prescribed by the NIS standard. From the study, it was concluded that the presence of Cadmium in the well waters indicated that the water is unfit for consumption.
The pragmatics of figures of speech in teacher - student conflicts: An analysis of selected EFL classroom exchanges in Secondary Schools
Authors: Hagbe Edwige Damaris
Published: May 2023

The present article analyses the use of figures of speech in situations of conflict in the EFL classroom; it seeks to report how these linguistic devices are exploited by EFL teachers and students to perform a variety of acts during classroom exchanges. In a corpus of 70 EFL teacher student exchanges, we have appraised the use of figures of speech by EFL teachers and students in conflict situations in order to derive semantic and pragmatic meanings from the language choices. As a matter of fact, the present article focusses on figures of comparison as well as figures of exaggeration as used by classroom actors in the context of disagreement with a view to identifying the speech acts they perform in class. By means of direct class observation, 70 EFL classes were observed, recorded and transcribed; the analysis of the selected relevant data was done in accordance with the theory of speech acts and the politeness theory by Austin and Searle 1962 as well as Leech 1983. The findings revealed that in situations of conflict, figures of comparison and exaggeration served the purpose of performing face threatening acts which are undeniable conflict markers.

Set up of a Microbial Fuel Cell for the Treatment of a Garden Compost Leachate: Impact of the External Polarizing Electric Resistance Upon the Chemical Oxygen Demand Removal
Authors: Laaz Imene , Kameche Mostefa , Innocent Christophe
Published: May 2023

Microbial fuel cells (MFCs) are new and growing renewable energy devices. They transform chemical products into electricity with the help of microorganisms (enzymes, bacteria, microbes, etc.) acting as biocatalysts. They are nowadays displaying technological development since they concomitant simultaneously the wastewater treatment and the electric power generation. These two novelties incite researchers in the field, the utilization of this promising technology. As a matter of fact, a bioelectrochemical fuel cell has been elaborated and set up for garden compost leachate treatment. Following a previous study on the microbial anode formed from wastewater under the application of an electric potential either positive or negative by using chronoamperometry. In this work, we propose the simple method of connecting the two electrodes (anode and cathode) by electrical resistance, to flow a current. The impact of the polarizing electric load on the achievement of the MFC has therefore been studied. Moreover, the chemical oxygen demand (COD) removal for the MFC running for 7 days has been also investigated. It decreased and showed simultaneously an increase in the cell voltage. Thus, the effects of the external load on the current and power generation, as well as on pollutant removal, have been studied by modifying each time the external load. The external polarizing resistance (EPR) was increased from 1 to 10 kΩ, to assess the pollutant decay of the organic matter contained in the wastes. As a result of this, the voltage was increased, whilst the current was decreased, with increasing values of the EPR. The results have been discussed with respect to the type and the predominant microorganisms (electrogenic/fermentative) being involved during the generation of the electric current. This new technology is very promising for converting waste into electricity by offering a way to clean up the polluted environment.

GRAFISMO: UMA ESTRATÉGIA DE ENSINO E APRENDIZAGEM
Authors: Boeira Luciana
Published: May 2023

O processo de aquisição do conhecimento pelo homem é uma atividade complexa do pensamento a qual envolve faculdades mentais tais como a imaginação, o raciocínio e a memória. Por tamanha complexidade, é comum que surjam obstáculos difíceis de vencer impedindo o sujeito a conhecer. Um das primeiras dificuldades é a não visualização dos novos conteúdos pela imaginação – pois ocorre uma escuridão cognitiva. O grafismo é uma técnica de estudos que foi sistematizada e teorizada para auxiliar os estudantes das engenharias a enfrentar este obstáculo e assim chegar de fato ao conhecimento. Como produto pedagógico da Tese Imaginação e Grafismo uma estratégia aplicada aos discentes de Ciências Exatas e Tecnológicas da Universidade Federal do Recôncavo da Bahia, esta técnica de estudos foi aplicada como uma estratégia de ensino e aprendizagem e verificada através de uma pesquisa-ação de abordagem qualitativa. Após a verificação e análise dos dados coletados através de dois ciclos de ação da pesquisa, constatou-se que a execução do grafismo pelos estudantes durante o processo de aquisição do conhecimento e resolução de problemas de engenharia: auxilia e promove a superação da escuridão cognitiva através da ilustração, visualização e organização gráfica dos elementos do objeto do conhecimento; direciona o movimento do pensamento; auxilia na ascensão do conhecimento e estimula o exercício da imaginação. Extrapolando os aspectos empíricos, a estratégia de ensino e aprendizagem grafismo apresentou e validou entendimentos tais como: levar o estudante à percepção do saber é uma forma de estímulo a busca por saber mais e, desta maneira, uma forma de estimular o desenvolvimento de sua autonomia intelectual.
Integrity Assessment of Wall Distorted of Buried Gas Pipeline
Authors: Herucakra Wira , Adnyani Luh Putri , Megantoro Lukytoardi
Published: May 2023

In the oil and gas industry, the pipeline is the main mode to transport the product and can be applied for long-distance transportation; hence some pipe segments may be buried underground. Buckling as the main cause of pipeline deformation and failure is often found at the in-service buried pipeline during inspection activity. Changes in laying conditions such as design and operational parameters, human activity and geological movement can affect the redistribution of deformation that may lead to pipe buckling. This paper presents a methodology that integrates inspection results and finite element analysis for the distorted wall of the pipeline. Inspection reported anomaly cases of wall distorted at buried gas pipeline, and the result will be used to do stress analysis using finite element analysis. Three different conditions within the different treatment of bedding conditions were assessed: pipe buried on uncompacted soil, pipe buried with rock bedding, and pipe buried in compacted soil. The result shows that the deteriorated pipe can be considered acceptable when buried in compacted soil. This condition may be used for further action and consideration, such as a mitigation strategy to maintain the safety and integrity of the deteriorated pipe.

The high cost of certification and the low pass percentage in welding certification are common issues for beginner welders. The use of Augmented Reality (AR) technology is expected to solve these issues. The results of the penetrant, bending, and tensile tests showed that the welder who had used the AR welding machine produced better welding specimens than before they practiced using the AR welding machine. The penetrant test after beginner welder practiced using the AR welding machine produces rounded defects with a defect size of 1,44 mm (accepted by ASME Section V), whereas before they practiced using the AR welding machine it produces defects that cannot be accepted by the criteria. The maximum open discontinuity length in the bending test on the welded specimen after welder practiced using the AR welding machine is 2,90 mm (accepted by ASME Section IX), whereas the bending test before welder practiced using the AR welding machine is not accepted by the citeria. The tensile test results after welder practiced using the AR welding machine were 410,00 and 455,66 N/mm2 for the maximum tensile stress. This value exceeds the minimum tensile strength of SA-36 carbon steel, which is 400 N/mm2. When compared to the specimen before the welder practiced using the AR welding machine, the modulus of elasticity produced after the welder practiced using the AR welding machine is also smaller, indicating that the material has better elasticity. Based on the results of the tests, it can be seen that the AR welding machine can be used for the implementation of competency certification because the quality of the weld results is better, there are fewer risks (sparks, eye irritation, and burns), and the use of welding consumables is reduced

In recent years, marine survey operations such as survey operations for underwater communication cables and tsunami early warning systems have become an annual activity involving research vessels in Indonesia. Along with the increasing age of the ship, it will be followed by a decrease in the performance of the machinery system. Maintenance of the machinery system is carried out to maintain the desired performance by ship users. However, with a large number of machinery system equipment and limited resources, an analysis is needed to prioritize which equipment or components need regular maintenance and monitoring activity. By classifying all assets into a hierarchical form and performing a risk-based criticality analysis, equipment will be prioritized based on the probability of failure and the level of consequence. By determining the probability of failure of a component based on historical data and reference failure data, and determining the consequences for health safety (HS), production (P), Environment (E), and Containment (Cn), the risk would be obtained. From this analysis obtained as many as 766 equipment and components consisting of 38 rotary equipment, 45 static equipment, 196 piping components, and 487 instruments. The risk analysis obtained as many as 23 (3%) of equipment in H (high), 138 (18%) in the M (medium) condition, and 605 (79%) in the L (low) condition. The criticality results determined that 161 (21%) equipment in H & L conditions would be carried out planned maintenance and 605 (79%) equipment in low condition would be carried out unplanned maintenance.

Published: May 2023

The characteristics of the passengers have a significant impact on how the evacuation procedures are carried out. During an evacuation, the amount of time it takes depends on how quickly passengers move. There is a correlation between age and travel speed, but not always. As a result of this problem, a significant number of passengers were unable to make it to the assembly point in time for the evacuation, which may have resulted in fatalities. An evacuation simulation will be carried out aboard passenger ships in the event of a fire. This research will employ agent-based modeling to perform the simulation, and it will include modifications for day and night, as well as for the number of emergency stairs used. The findings of this study are the simulation times for the evacuation of passengers and crew for each scenario, with the shortest time for evacuation occurring during the daytime with operational emergency stairs, clocking in at 36.51 minutes, and the longest time for evacuation occurring during the night with damaged emergency stairs, clocking in at 47.43 minutes. Both times are given in minutes. According to the findings, the evacuation circumstances satisfied the standards set by the IMO, which demanded that the entire amount of time spent evacuating be less than or equivalent to sixty minutes

Poor high-temperature stability (HTS) and weak microwave absorption performance (MAP) are a major restriction for wave-absorbing materials in elevated temperature ambient. Consequently, the Stöber process and the sol–gel method are first devised and used to create multi-core/shell SiO2@Al2O3 nanostructures (MCSNs) on Ti3AlC2 (TAC). The MCSNs with a thickness of 135–215 nm raise the starting oxidation temperature of the matrix by 400°C. Furthermore, the weight gain drops from 17.44 to 2.32% within 1 h at 800°C. The effective absorption bandwidth with a reflection loss (RL) ≤ −10 dB of the MCSNs-coated TAC is 3.25 GHz (8.68–11.27 and 11.63–12.29 GHz) at a thickness of 2.0 mm, which is 4.7 times that of the matrix. The minimum RL is reduced by a factor of 2.77 from −10.68 to −29.55 dB. The enhanced MAP is due to the introduced multiple reflection events and scattering mechanism as well as the enhanced electronic polarization, interface polarization, and polarization relaxation. The growth of the MCSNs provides a reference for the design and preparation of bifunctional materials with good HTS and MAP.

Published: May 2023

Objectives

This research compared the curative effect and safety of camrelizumab plus tyrosine kinase inhibitors (TKIs) combined with transcatheter arterial chemoembolization (TACE) to those of camrelizumab plus TKIs for the treatment of intermediate-advanced hepatocellular carcinoma (HCC).

Methods

From January 2019 to July 2021, 47 patients with intermediate-advanced HCC were included in this retrospective study. After screening, 44 eligible patients were split into two arms: the camrelizumab + TKI + TACE arm (n=28) and the camrelizumab + TKI arm (n=16). The primary endpoints were overall survival (OS) and progression-free survival (PFS), while tumor response and adverse events (AEs) served as secondary endpoints.

Results

The median OS was 12.60 months for the 44 patients. The median PFS (p=0.0248, 7.20 vs. 3 months), objective response rate (ORR) (21.43 vs. 6.25%) and disease control rate (DCR) (57.14 vs. 18.75%) were better for patients in the camrelizumab + TKI + TACE arm than in the camrelizumab + TKI arm. After correcting for the effects of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and total bilirubin (TBil) levels, the treatment effect of the camrelizumab + TKI + TACE arm (HR=0.330, 95% CI=0.130–0.880, p=0.026) was still superior. The common AEs in the two groups included reactive cutaneous capillary hyperplasia (n=17), myelosuppression (n=19) and liver dysfunction (n=12). However, AEs of grade ≥3 were equal between the groups.

Conclusions

Camrelizumab + TKI + TACE therapy was more effective than camrelizumab + TKI therapy for intermediate-advanced HCC, and toxicity was manageable.

Objective

Worldwide, gastric cancer (GC) is one of primary reasons for cancer-related deaths. However, the pathogenic mechanism underlying GC remains to be fully understood. MicroRNAs are momentous regulators of diverse biological progression in cancer. Even though the ability of miR-219a-1-3p to inhibit malignant progression in pancreatic cancer have been previously reported, its role in GC remains to be elucidated.

Methods

Quantitative real-time PCR (qRT-PCR) was performed to measure miR-219a-1-3p expression levels in collected GC samples (n=98) and paired nearby non-tumor tissues. Cell proliferation, migration, and invasion assays were then conducted to explain the biological influences of miR-219a-1-3p in vitro. In vivo effects were confirmed by subcutaneously injecting miR-219a-1-3p overexpressing MGC-803 cells into nude mice. Methylation-specific PCR was employed to evaluate the CpG island upstream methylation condition of miR-219a-1-3p in collected clinical tissues (n=22), GC cell lines and GES-1 cells. GC cells were supplemented with 5-aza-2′-deoxycytidine to identify the miR-219a-1-3p expression changes using qRT-PCR.

Results

The miR-219a-1-3p expression was obviously suppressed in GC tissues relation to nearby non-tumor tissues, along with in GC cell lines in comparison to GES-1. Moreover, in vivo and in vitro functional evaluations indicated the function of miR-219a-1-3p in inhibiting the malignant characteristics of GC cells. Mechanistically, MiR-219a-1-3p expression was partly regulated utilizing DNA hypermethylation in GCs. In addition, overexpression of miR-219a-1-3p inhibited PI3K/AKT signaling.

Conclusions

MiR-219a-1-3p might function as a tumor suppressor in GC, and our investigation creates a foundation to diagnose of GC.
