Background: Testing is imperative to validate the functionalities and safety of autonomous driving systems. Simulated scenario-based testing is commonly adopted for autonomous driving systems, which aims to construct various driving scenarios and validate the autonomous driving systems in simulation. Nevertheless, identifying relevant test scenarios, especially critical ones that expose hazards or
High flux, monolithic water purification filters based on polylactic acid (PLA) functionalised with fish scale extracted hydroxyapatite (HAp) were prepared by solvent-assisted blending and thermally induced phase separation (TIPS), followed by twin-screw extrusion into filaments and processed via three-dimensional (3D) printing. The printed filters with consistent pore geometry and channel interco
Vaccine hesitancy, defined as the reluctance or rejection in receiving a vaccine despite its availability, represents a major challenge to global health efforts aiming to control the ongoing COVID-19 pandemic. Understanding the possible factors correlated with COVID-19 vaccine hesitancy using a refined well-informed approach can be helpful to address the phenomenon. The current study aimed to eval
Escherichia coli BL21 (DE3) with a plasmid vector pET-22b (+) carrying xylanase coding gene isolated from an extremely thermophilic bacterium, Thermotoga sp. was used in this work for enhanced production of recombinant xylanase. The study was focused on optimization of lactose based induction for enhanced production of xylanase. Data collected from OFAT and DoE based trails indicated that initiati
A new 130 to 140 Ma mafic dyke swarm, is identified in western South Africa. It consists of the previously undated Cederberg dyke swarm (CDS), for which we report U-Pb ID-TIMS baddeleyite ages of 131.4 ± 4.5 Ma (Knersvlake subswarm) and 133.0 ± 1.5 Ma (Doring-Tanqua subswarm).40Ar/39Ar dates on these two samples and two additional dates of the Doring – Tanqua subswarm cluster between 128.5 ± 1.4 M
Coprophagy is a behavior where animals consume feces, and has been observed across a wide range of species, including birds and mammals. The phenomenon is particularly prevalent in juveniles, but the reasons for this remain unclear. One hypothesis is that coprophagy enables offspring to acquire beneficial gut microbes that aid development. However, despite the potential importance of this behavior
To ensure that cities and urban ecosystems support human wellbeing and overall quality of life we need conceptual frameworks that can connect different scientific disciplines as well as research and practice. In this perspective, we explore the potential of a traits framework for understanding social-ecological patterns, dynamics, interactions, and tipping points in complex urban systems. To do so
The ultramafic-mafic layered igneous Molopo Farms Complex straddles the border between South Africa and Botswana. Younger cover obscures this igneous complex and its country rocks, which are generally assigned to the Paleoproterozoic Transvaal Supergroup. The area intruded by the complex is characterized by abutting and contrasting successions of the upper Transvaal Supergroup (i.e., the Pretoria
This article examines Jerome’s use of bridal and military imagery in his writings to male and female ascetics. The metaphor of the “bride” and the “soldier” had been used in earlier Christianity to describe the Christian identity of the baptized person, and in the writings of Jerome and other fourth-century ascetic writers, these motifs came to be increasingly employed in discourses on the asceticThis article examines Jerome’s use of bridal and military imagery in his writings to male and female ascetics.

The notion of the “flesh” plays an important part in Jerome’s theology at large, and this is no less true of his anti-Pelagian polemics. Against what he presents as the Pelagian idea of apatheia, Jerome points out that due to our existence in the flesh, we cannot hope to be free from sin during our earthly lives. A central accusation against Pelagianism which Jerome expresses in this connection, iThe notion of the 'flesh' plays an important part in Jerome’s theology at large, and this is no less true of his anti-Pelagian polemics. In opposition to what he presents as the Pelagian idea of apatheia, Jerome claims that due to our existence in the flesh, we cannot hope to be free from sin during our earthly lives.

Many children in primary school listen and learn through their second language, often under noisy listening conditions. This thesis is based on assessments of 7 to 9-year-old primary school children (N=98) attending Swedish schools in areas of low socio-economic status where most students had immigration background. The overall aim of this thesis was to increase knowledge on how multitalker babble
Hotspot tracks (chains of seamounts, ridges, and other volcanic structures) provide important records of plate motions, as well as mantle geodynamics, magma flux, and mantle source compositions.
