SALINAS - An implicit finite element structural dynamics code developed for massively parallel platforms

As computational needs for structural finite element analysis increase, a robust implicit structural dynamics code is needed which can handle millions of degrees of freedom in the model and produce results with quick turn around time. A parallel code is needed to avoid limitations of serial platforms. Salinas is an implicit structural dynamics code specifically designed for massively parallel platforms. It computes the structural response of very large complex structures and provides solutions faster than any existing serial machine. This paper gives a current status of Salinas and uses demonstration problems to show Salinas' performance

Transplanting the leafy liverwort Herbertus hutchinsiae : A suitable conservation tool to maintain oceanic-montane liverwort-rich heath?

Thanks to the relevant landowners and managers for permission to carry out the experiments, Chris Preston for helping to obtain the liverwort distribution records and the distribution map, Gordon Rothero and Dave Horsfield for advice on choosing experimental sites and Alex Douglas for statistical advice. Juliane Geyer’s help with fieldwork was greatly appreciated. This study was made possible by a NERC PhD studentship and financial support from the Royal Botanic Garden Edinburgh and Scottish Natural Heritage.Peer reviewedPostprin

Progress in the synthesis of sustainable polymers from terpenes and terpenoids

The imminent depletion of resources derived from fossil fuels is a major concern for today’s society. 300 Mt of polymers are used every year in the form of plastics, most commonly derived from fossil fuels, hence the necessity to find new materials based on renewable resources. This review explores the utilisation of monoterpenes and terpenoids – a family of abundant and inexpensive natural products – as promising renewable monomers. Terpenes can be directly used in polymerisations or converted into bespoke monomers through organic transformations. The use of terpenes for the production of renewable plastics has been a prevalent topic of research for the past few decades. Early research focused on cationic polymerisation of terpenes by way of their alkene moieties; however, more recently terpenes are being functionalised to incorporate handles for a larger range of polymerisation techniques. Herein an assessment of the future prospects for the use of these small functional molecules to synthesise novel and valuable renewable materials is presented

Overview of fetomaternal outcome in twin gestation

Background: Twin pregnancy, involving the presence of two fetuses in the uterus, has intrigued humanity across history. Key challenges presented by twin pregnancies include prematurity, low birth weight (LBW), intrauterine growth restriction (IUGR), birth trauma, asphyxia, and congenital anomalies. Preterm delivery poses the most significant risk, contributing to elevated perinatal mortality, neonatal morbidity, and long-term health issues for twins. Methods: Retrospective study at Smt NHL Municipal Medical College analyzed 80 twin pregnancies from July 2022 to January 2024. Data included patient demographics, complications, and neonatal outcomes, informing findings through data analysis. Results: In this study, the majority were under 30 years old (56%) and primigravida (68%), with 48% having a BMI over 30. Common complications included preterm labor (70%), pregnancy-induced hypertension (27.5%), and gestational diabetes (20%). Most twin pregnancies were dichorionic diamniotic (80%). Caesarean section rate was 47.5%. Deliveries mostly occurred between 33-36 weeks gestation, with cephalic-cephalic presentation being most common (40%). Neonatal complications were primarily prematurity (50%), resulting in high NICU admissions (62%) and a neonatal death rate of 13.76%. Conclusions: Multiple pregnancies require early diagnosis and vigilant care to reduce maternal and perinatal risks. Access to skilled healthcare providers and advanced facilities is crucial. Antenatal care must be strengthened for timely referrals. Ultrasonography aids early complication detection. Further advancements and awareness are essential for improved outcomes

Troubling the exclusive privileges of citizenship: mobile solidarities, asylum seekers, and the right to work

This article discusses asylum seekers and the right to work in the UK. Differential access to the labour market is one of the ways in which the state maintains a distinction between British citizens, who ‘belong’, and non-citizens who do not. While such a policy approach garners widespread support amongst the general public of citizens, it does not go uncontested. This article discusses a UK-based campaign, ‘Let Them Work’, which has sought to influence the government in extending the right to work to asylum seekers. In doing so, it demonstrates the ways in which the stratified regime of citizenship rights is contested politically, and explores how such contestation troubles the exclusive privileges of citizenship by enacting mobile solidarities from marginalised spaces

Critical perspectives on ‘consumer involvement’ in health research: epistemological dissonance and the know-do gap

Researchers in the area of health and social care (both in Australia and internationally) are encouraged to involve consumers throughout the research process, often on ethical, political and methodological grounds, or simply as ‘good practice’. This paper presents findings from a qualitative study in the UK of researchers’ experiences and views of consumer involvement in health research. Two main themes are presented in the paper. Firstly, we explore the ‘know-do gap’ which relates to the tensions between researchers’ perceptions of the potential benefits of, and their actual practices in relation to, consumer involvement. Secondly, we focus on one of the reasons for this ‘know-do gap’, namely epistemological dissonance. Findings are linked to issues around consumerism in research, lay/professional knowledges, the (re)production of professional and consumer identities and the maintenance of boundaries between consumers and researchers

Performative Work: Bridging Performativity and Institutional Theory in the Responsible Investment Field

Callon’s performativity thesis has illuminated how economic theories and calculative devices shape markets, but has been challenged for its neglect of the organizational, institutional and political context. Our seven-year qualitative study of a large financial data company found that the company’s initial attempt to change the responsible investment field through a performative approach failed because of the constraints posed by field practices and organizational norms on the design of the calculative device. However, the company was subsequently able to put in place another form of performativity by attending to the normative and regulative associations of the device. We theorize this route to performativity by proposing the concept of performative work, which designates the necessary institutional work to enable translation and the subsequent adoption of the device. We conclude by considering the implications of performative work for the performativity and the institutional work literatures
