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. The Tristan-Gough-Walvis Ridge (TGW) hotspot track, extending from the active volcanic islands of Tristan da Cunha and Gough through a province of guyots and then along Walvis Ridge to the Etendeka flood b

The globally increasing contents of microplastics (MP) in ecosystems have become a serious environmental problem with far-reaching and at present unpredictable consequences for both aquatic life and human well-being. Until recently, most research on MP focused on marine ecosystems. Research on the occurrence of MP has lately started to focus on freshwater environments. This comprehensive and criti

Changes in land cover and land use (LULC) are one of the main drivers of erosion and runoff. How ever, most research has relied on short-term observations and only focused on one or two land cover types. We investigated the long-term trade-off between common agricultural land covers (sugarcane, pasture, and soybean), runoff, and soil loss rates. We compared these to native forest (wooded Cerrado)
