Ratios for urban discharge and recipient flow during different time intervals are presented and discussed. The quality of the urban discharge is illustrated through pollutographs.-Authors

Extreme environmental conditions make soils of the hyper-arid Atacama Desert one of the most hostile habitats for life on the planet. During the short intervals of moisture availability that occur, it remains unresolved how soil microorganisms physiologically respond to such dramatic environmental changes. Therefore, we simulated a precipitation event – without (H2O) and with (H2O + C) labile carb

This study investigated differences and similarities in outcomes of analyses based on phenomenography and variation theory. We used the same data for both analyses to highlight the assumptions of each approach. Participants were 198 students (grades 7–9) who provided written answers to the question ‘What is learning?’. The phenomenographic analysis identified qualitatively different categories rep

English is today learnt in multitudes of settings worldwide, making it difficult to characterize relationships between motivation and context in generalized terms (Ushioda 2013). In settings where students have extensive encounters with English outside school, a reluctance to invest effort in formal learning has been observed. To investigate ways in which out-of-school encounters impact on motivat

Transitions to low-carbon energy technologies and other forms of climate mitigation tend to involve disempowerment and environmental injustices of various kinds. This paper argues that such tendencies are inherent in the social rationale of technological systems promoted by the logic of the world market. The production and operation of technological artifacts are imbued with economic rationality a

Background: A growing body of evidence shows that prenatal exposure to phthalates affects child development. Since many phthalates have been shown to alter endocrine signaling, they may influence reproductive development, neurodevelopment, and child behavior. Indeed, a few studies reported associations between prenatal phthalate exposure and gender-specific play behavior. However, evidence for thi

Context. Cool stars, such as M giants, can only be analyzed in the near-infrared (NIR) regime due to the ubiquitous titanium oxide features in optical spectra of stars with Teff<4000 K. In dust-obscured regions, the inner bulge and Galactic center region, the intrinsically bright M giants observed in the NIR are an optimal option for studying stellar abundances and the chemical evolution of stella

Parkinson’s Disease (PD) is a neurodegenerative and progressive disorder characterised by intracytoplasmic inclusions called Lewy bodies (LB) and degeneration of dopaminergic neurons in the substantia nigra (SN). Aggregated α-synuclein (αSYN) is known to be the main component of the LB. It has also been reported to interact with several proteins and organelles. Galectin-3 (GAL3) is known to have a

Advancement of the maxilla may increase the distance between the soft palate and the posterior pharyngeal wall in patients with cleft lip and palate, implying a risk of velopharyngeal dysfunction. The aim was to evaluate long-term speech outcome in a consecutive series of patients treated with distraction osteogenesis (DO). Fourteen out of the 16 patients agreed to participate. A long-term speech

Bone mineralization involves a complex orchestration of physico-chemical responses from the organism. Despite extensive studies, the detailed mechanisms of mineralization remain to be elucidated. This study aims to characterize bone mineralization using an in-vivo long bone fracture healing model in the rat. The spatio-temporal distribution of relevant elements was correlated to the deposition and

Acoustophoresis has become a powerful tool to separate microparticles and cells, based on their material and biophysical properties, and is gaining popularity in clinical and biomedical research. One major application of acoustophoresis is to measure the compressibility of cells and small organisms, which is related to their contents. The cell compressibility can be extracted from the acoustic mob

Portugal's real income per head grew by a factor of eight during the second half of the twentieth century, a period of fast convergence towards Western European living standards. We use a new sample of about 3,400 infants and children living in Lisbon to document trends in the prevalence of stunting and wasting between 1906 and 1994. We find that stunting and wasting fell quickly from around 1950,

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

The understanding of small cell lung cancer (SCLC) biology has increased dramatically in recent years, but the processes that allow SCLC to progress rapidly remain poorly understood. Here, we advocate the integration of rapid autopsies and preclinical models into SCLC research as a comprehensive strategy with the potential to revolutionize current treatment paradigms.

Hur nådde fossildriven teknik Egypten på sin väg mot global dominans? Denna avhandling presenterar en socioekologisk historia av energiteknologier i förkoloniala Egyptens jordbruksproduktion (1820-talet-76). Den placerar dem i 1800-talet, början på Kapitalocenens epok; och i Egyptens fall är detta samtidigt en del av Storbritanniens fossila imperiums uppkomst. Denna avhandling behandlar hur ångmasHow did fossil-fuelled technology find its way to Egypt on its way to global dominance? This thesis presents a socioecological history of energy technologies in agrarian production in pre-colonial Egypt (1820s – 76). It situates them in the nineteenth century, understood as the beginning of the epoch of the Capitalocene; and in Egypt’s case, this is simultaneously part of the rise of Britain’s fos

Using a data set of 1.1 million speeches drawn from UK House of Commons debates during 1997–2017 and a combination of automated and manual content analysis, this study addresses three interrelated questions. First, to what extent are minoritised women constitutively represented in parliamentary debates? Second, which MPs do so? Third, how do MPs’ race and gender affect how they represent minoritis

Within the Anabar shield in the northern part of the Siberia, Late Precambrian mafic igneous units are widespread, which form dyke swarms of different ages of different trends. This paper presents new data on the composition, structure and U-Pb dating of the E-W trending Kengede dyke swarm. Three new U-Pb ID-TIMS baddeleyite ages (1496±7, 1494±3 and 1494±5 Ma) were obtained from three dykes, indic

Popular Abstract in SwedishEn av de viktigaste forskningsfrågorna inom matematikutbildning handlar om förståelse. Det huvudsakliga syftet med den här avhandlingen har varit att nå insikt i olika förståelseformer i skolmatematik och former av lärandeidentiteter i två lärandemiljöer. Avhandlingens specifika fokus var flexibla sätt att urskilja delar och avgränsa helheter och undersöka hur lärande inA central question in mathematics education research concerns understanding. The main objective of the present thesis has been to obtain insights into flexible modes of knowing in school mathematics in two school class contexts, and how these relate to modes of being a learner in these contexts, with specific focus on learners’ flexible ways of discerning parts and delimiting wholes, and how they
