Determinants of health-related quality of life in people with Human Immunodeficiency Virus, failing first-line treatment in Africa

Background: Antiretroviral treatment improves health related quality of life (HRQoL) of people with human immunodeficiency virus (PWH). However, one third initiating first-line treatment experience virological failure and the determinants of HRQoL in this key population are unknown. Our study aims to identify determinants of among PWH failing antiretroviral treatment in sub-Saharan Africa. Methods

Joint optimization of land carbon uptake and albedo can help achieve moderate instantaneous and long-term cooling effects

Both carbon dioxide uptake and albedo of the land surface affect global climate. However, climate change mitigation by increasing carbon uptake can cause a warming trade-off by decreasing albedo, with most research focusing on afforestation and its interaction with snow. Here, we present carbon uptake and albedo observations from 176 globally distributed flux stations. We demonstrate a gradual dec

Making sense of chemical equilibrium : productive teacher-student dialogues as a balancing act between sensemaking and managing tension

Navigating the observational, symbolic, and theoretical knowledge domains of chemistry is crucial for chemistry sensemaking. However, this has been shown to be particularly challenging for students of chemistry. In order to reach government standards for sensemaking in the chemistry subject, it is important to investigate how chemistry teachers can sustain sensemaking practices in their classrooms

Extending StringSpinner to handle vector-meson spin

Quark spin effects in hadronization were recently included in the PYTHIA 8 Monte Carlo event generator for the simulation of the deep inelastic scattering (DIS) process off a polarized proton or neutron target. The spin effects were activated via the external StringSpinner package, which is based on the string+P03 model of polarized hadronization, and were restricted to the production of pseudosca

The Dual Role of Insurance in Input Use: Mitigating Risk Versus Curtailing Incentives

Insurance can encourage the use of risk-increasing inputs, but it can also decrease people's incentives to exert effort when the latter is difficult to monitor. This effort reduction can be associated with a decrease in the use of effort-complementary inputs. I study a model of risk-sharing that allows for both effects of insurance on input use and use the latest ICRISAT panel to structurally esti

Concomitant interfacial spin fractal transformation and exchange bias in a magnetic shape memory alloy

Small-angle neutron scattering is used to study the exchange bias effect in Mn50Ni40Sn10. The martensitic transformation is found to be responsible for the nanometer-scale spin clusters (SCs) inside the low-temperature ferromagnetic (FM) martensite phase. The magnetic field dependences of the SCs and FM domains exhibit an asymmetry that characterizes the exchange bias. We find that the surface geo

Neutron adiabaticity and its impact on data analysis, illustrated for polarized GISANS

The significance of neutron spin adiabaticity in the data analysis of polarized Grazing Incidence Small Angle Neutron Scattering (GISANS) is discussed, with the aim of minimizing the number of simulation parameters of complex magnetic models within the neutron scattering cross-section. We illustrate how an estimate of the neutron polarization direction and adiabaticity can be obtained by magnetic

Polarisation Development at the European Spallation Source

To meet the ever-increasing user demand, eleven of the fifteen European Spallation Source (ESS) instruments under construction aim to offer polarised neutrons for user experiments. They include an imaging instrument, a SANS instruments, two reflectometers, three diffractometers, and four spectrometers. In conjunction with in-kind contributions and instrumentation grants, the ESS Polarisation Proje

“Meme-Ing” Peace in Northern Ireland : Exploring the Everyday Politics of Internet Memes in Belfast Riots

How do Internet memes about political violence in postwar Belfast speak to or against the peacebuilding process in Northern Ireland? Our findings demonstrate three dominant ways in which memes engage with such violence: (a) poking fun at violence, (b) poking fun at rioters, and (c) normalizing violence. Memes poking fun at violence destabilize the banal nationalism underpinning the conflict in Nor

Beyond "Volute Capitals" : Materials, Meaning, and Adaptations of a Phoenician Motif

The stylized volute motif is attested throughout the Levant and in areas of Phoenician settlement or cultural influence. Much of the debate of this motif has focused on the volute’s appearance in Israelite monumental architecture (the so-called Proto-Aeolic capital). This article provides a fresh discussion of the motif’s depiction within Phoenician art and iconography through various media, inclu

Making and Breaking Gender Inequalities in Work

This timely book expertly analyses the persistence of gender inequalities in work. Despite the progress made through frameworks regulating work and employment relations, the COVID-19 pandemic exposed and exacerbated gender divides in labour markets. The authors present innovative ways to promote gender equality in a variety of industrial relations systems, welfare state models and labour market se

Grain legume-cereal intercropping enhances the use of soil-derived and biologically fixed nitrogen in temperate agroecosystems. A meta-analysis

Grain legumes are known for their benefits to deliver ecosystem services on provisioning of protein-rich food and feed, reducing greenhouse gas emissions through the symbiotic nitrogen fixation function and diversification of cropping systems. Intercropping is an agroecological practice in which two or more crop species are grown simultaneously in the same field, thereby maximizing the use of reso

Cropping system diversification is a key factor in developing more sustainable cropping and food systems. The agroecological practice of intercropping, meaning the simultaneous cultivation of two or more species in the same field, has recently gained renewed interest as a means of ecological intensification in European agricultural research. We discuss some recent research developments regarding 1

Multiscale multiphase simulations at the gas channel/gas diffusion layer interface inside polymer electrolyte fuel cells

A computational fluid dynamic model describing a straight channel, relevant for water removal inside a PEFC, is developed. A volume of fluid (VOF) approach is used to investigate the two-phase interface resolved flow behavior inside the gas channel including the gas diffusion layer (GDL) surface. The size and contact angle of the liquid inlet at the interface are calculated with the lattice Boltzm

Analysing Tortuosity for Solid Oxide Fuel Cell Anode Material : Experiments and Modeling

Solid oxide fuel cells (SOFCs) directly convert chemical energy to electricity with high electrical efficiency. It involves gas transport through the porous electrode to the three-phase boundaries (TPB). The tortuosity of gas transport relates the bulk diffusion of gas in free space to the effective diffusion coefficient of gas migrating through a porous material. Therefore, determining the tortuo
