A two-stage polyethylene glycol (PEG)-phosphate aqueous two-phase system was used for purification of a highly thermostable and alkaline active recombinant xylanase. Response surface methodology (RSM) and artificial neural network (ANN) have been used to develop predictive models for simulation and optimization of purification process. Effects of pH, PEG molecular weight, concentrations of phospha
Research on (verbo-) pictorial metaphors and other rhetorical figures is primarily focused on the genre of advertising, leaving other genres under-investigated. In this study, we focus on street art, a visually perceived cross-cultural medium used to address sociopolitical issues. This genre typically combines two interacting semiotic systems – language and depiction – and is thus a form of polyse
The shortfalls in the quality, quantity, and reliability of agriculture performance data are neither new nor confined to Sub-Saharan Africa (SSA). It is, however, a more dire challenge given the overwhelming importance of agriculture in the economies of most countries in the region in terms of food security and poverty reduction. While farmers’ self-reported (SR) data on crop outputs and farm size
Removing obstacles to e-commerce in the Single Market and ensuring effectivetaxation in the context of the digital economy has been high on the political agendaboth in the European Union and beyond. Recently the VAT rules on cross-border ecommerce have gone through a thorough modernisation with a package of newprovisions in the EU VAT legislation coming into effect as of 2019 and 2021.

To improve the management of the European eel (Anguilla anguilla) in freshwater, it is essential to define important lotic habitats. Electrofishing data from 289 wadeable, hard-bottom sites in 69 Swedish coastal rivers and streams, originally surveyed for salmonid monitoring, were used to evaluate the effects of sampling- and habitat-related factors on eel occurrence. Probability of eel occurrence
Objective This study investigates various kinds of knowing that European parents use when caring for their children with congenital adrenal hyperplasia (CAH). Methods Semi-structured qualitative interviews with 20 parents of 22 children with CAH. Results Parents emphasized the importance of knowing what CAH is and what support their child needs, but also knowing how to cope and make sense of the
BACKGROUND: Biopsies are routinely obtained in the workup of large colorectal polyps before endoscopic resection. OBJECTIVE: This study aimed to examine how reliable biopsies are in terms of reflecting the true histopathology of large colorectal polyps, in the clinical routine. DESIGN: This is a retrospective study. SETTINGS: Data from patients undergoing polypectomy of large colorectal polyps at
To date, little is known about the effects of violence on the educational outcomes of adolescents in disadvantaged communities in South Africa. In response, self-report data were collected from a socioeconomically disadvantaged sample of 503 adolescents aged 10 to 18 participating in a child abuse prevention trial in the Eastern Cape. Adolescents were purposively selected in the trial. This study
This article explores the similarities between the two most successful Swedish films of the past years. Through a focus on the two elderly protagonists the article discusses how the films acknowledge challenges in these men’s lives and in both contemporary and past society, but effectively repackage any serious issue in a form that remains palatable to audiences in Sweden and internationally. Them
Hemoglobin (Hb)-based oxygen carriers (HBOCs) have been engineered to replace or augment the oxygen carrying capacity of erythrocytes. However, clinical results have generally been disappointing, in part due to the intrinsic oxidative toxicity of Hb. The most common HBOC starting material is adult human or bovine Hb. However, it has been suggested that fetal Hb may offer advantages due to decrease
Control of nutrients, mainly nitrogen (N) and phosphorus (P), plays a significant role in preventing cyanobacterial blooms (harmful algal blooms (HABs)). This study aims at evaluating changes in the risk of the occurrence of cyanobacterial blooms and advancing the understanding of how nitrogen and phosphorus affect the growth of cyanobacteria in a eutrophic lake, Lake Vombsjön, in southern Sweden.
The analysis of stable isotopes assisted in identifying that groundwater in the Punata alluvial fan is mainly recharged by heavy flash floods, and the recharge from rainfall is of less importance. In addition, the hydrochemical analysis identified the Pucara River as the main source of recharge. Other streams in the north and northwest of the fan do not seem to contribute to the recharge. The hydr
Home care services are an important part of the Swedish social welfare system. Considering the size of the sector and the increasing future needs for home care, due to growing elderly populations, it is worrisome that problems in terms of injuries, sick leave and staff turnover appear common in this occupation. A problem for managing the situation is, however, that the current knowledgebase is fra
Stomatopods have an elaborate visual system served by a retina that is unique to this class of pancrustaceans. Its upper and lower eye hemispheres encode luminance and linear polarization while an equatorial band of photoreceptors termed the midband detects color, circularly polarized light and linear polarization in the ultraviolet. In common with many malacostracan crustaceans, stomatopods have
