Whether sources or sinks control wood growth remains debated with a paucity of evidence from mature trees in natural settings. Here, we altered carbon supply rate in stems of mature red maples (Acer rubrum) within the growing season by restricting phloem transport using stem chilling; thereby increasing carbon supply above and decreasing carbon supply below the restrictions, respectively. Chilling

This policy brief looks into the role of social norms to fight corruption in the school system in the Cau Giay district in Hanoi. An ongoing research project has conducted multiple ethnographic field studies in schools and included parents, teachers, and other school personnel in the research data. Their experiences and reflections are the core of this brief. The results show the existence of info

Urban green and blue infrastructure (GBI) and associated ecosystem services (ES) are increasingly recognized for their potential to address urban sustainability challenges. This has resulted in an increase in studies quantifying ES in cities. In this review, we analysed 850 peer-reviewed publications to characterize urban ES assessment in terms of geographical location, urban GBI type and methodol

Impalas are unusual among bovids because they have remained morphologically similar over millions of years-a phenomenon referred to as evolutionary stasis. Here, we sequenced 119 whole genomes from the two extant subspecies of impala, the common (Aepyceros melampus melampus) and black-faced (A. m. petersi) impala. We investigated the evolutionary forces working within the species to explore how th

Experiments using the Surface Force Apparatus (SFA) have found anomalously long-ranged charge–charge underscreening in concentrated salt solutions. Meanwhile, theory and simulations have suggested ion clustering to be a possible origin of this behavior. The popular Restricted Primitive Model of electrolyte solutions, in which the solvent is represented by a uniform relative dielectric constant, εr

Active vitamin D, 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)], plays a pivotal role in calcium homeostasis and bone metabolism. Circulating levels of 1,25(OH)(2)D(3) are thought to be dependent mainly on the activity of the renal cytochrome P450 enzyme 25-hydroxyvitamin D(3)-1alpha-hydroxylase (1alpha-hydroxylase), which is potently induced by PTH. However, 1alpha-hydroxylase activity or expressi

The purpose of the present article is to systematically investigate how people perceive collective threat and how such threat perceptions relate to political preferences. Existing threat taxonomies are mostly derived from top-down analyses and little attempt has been made to examine bottom-up how people spontaneously perceive threats. One area where this is of central importance is the relationshi

Objective Based on clinical experience gained over many years, the maximal haemostatic effect following administration of local anaesthetics containing epinephrine is generally believed to occur within 10 minutes. Surprisingly, it was found in a recent study, in which bleeding was quantified intraoperatively, that maximal haemostasis did not occur until 30 minutes. If this is indeed the case, the

The aim of the study was to identify changes in agricultural practices and periods of agricultural expansion and regression during the last 1,300 years in the South-Swedish Uplands. Sediments from the small lake of Skärpingsgölen (1.2 ha) were used to quantify land-cover at a local scale (c. 1 km radius) in 50-year intervals based on pollen analysis and the LOVE model (Local Vegetation Estimates).

BACKGROUND: Bacterial infection causes accumulation of neutrophils that release antimicrobial proteins including heparin-binding protein (HBP). In human airways, this neutrophil accumulation can be re-capitulated via intrabronchial exposure to lipopolysaccharide (LPS), a Toll-like receptor 4 (TLR4) agonist, that also causes a local increase in the neutrophil-mobilizing cytokine IL-26. Although LPS

Previous research has shown that language in job adverts implicitly communicates gender stereotypes, which, in turn, influence employees’ perceived fit with the job. In this way, language both reflects and maintains a gender segregated job market. The aim of this study was to test whether, and how, language in organizational descriptions reflects gender segregation in the organizations by the use

Local pseudorandom generators are a class of fundamental cryptographic primitives having very broad applications in theoretical cryptography. Following Couteau et al.’s work at ASIACRYPT 2018, this paper further studies the concrete security of one important class of local pseudorandom generators, i.e., Goldreich’s pseudorandom generators. Our first attack is of the guess-and

OBJECTIVE: The initiating events in the onset of pancreatitis are poorly understood. Possible candidates may be endogenous ligands, acting on receptors within ductal, acinar or stellate cells, which have previously been shown to cause a systemic inflammatory response syndrome. The aim of this study was to investigate whether acute pancreatitis could be induced by heparan sulphate (HS)infused into

Background and Aims: Results from prior studies of risk factors for intracerebral hemorrhage (ICH) are inconsistent. Few studies have investigated risk factors measured before the event and separately for different locations of ICH. We investigated risk factors for incident ICH in the population-based Malmö Diet and Cancer cohort. Method: Baseline information, assessed by a questionnaire and in a

Cities exhibit a rich and complex heterogeneity in people and activities. This poses a sizable challenge for planners when planning new neighbourhoods or the reconstruction of old ones as well as when considering the allocation of supply of and demand for amenities, e.g. kindergartens or health facilities. However, individual preferences may also exhibit common denominators that may provide struct

Ecosystem-based adaptation (i.e. the use of ecosystem services to adapt to climate change) and its mainstreaming into municipal planning to foster sustainable transformation is receiving increasing interest from both academic and governmental bodies. However, little is known about the pathways for its systematic implementation, or the extent to which it is already mainstreamed in municipal plannin

Populärvetenskaplig sammanfattning: Främmande gen ger fler skott Ibland händer det att arter i naturen byter gener med varandra. Frågan är hur det kan påverka deras förmåga att anpassa sig till sin miljö. Kan en extra gen till exempel få ett gräs att växa annorlunda, eller klara av torka bättre? Det är frågor vi försökt få svar på i den här studien—med hjälp av femhundra krukor gräs och ett växt

After the breakup of the Soviet Union Estonian economy found itself cut off from its main markets and production links. One major barrier in the economic transformation and diversification process that followed was the lack of necessary tacit productive knowledge in the country. Furthermore, local firms had no or only weak links to the global production and knowledge networks that function as impo

Denna studie ämnar öka kunskapen om hur kommunikativ likriktning mellan institutioner upprätthåller etablerade föreställningar om hållbar utveckling i samhället. Från ett socialkonstruktionistiskt perspektiv analyseras hur FN konstruerar diskurser kring hållbarhet i Agenda 2030 samt om dessa diskurser reproduceras i Helsingborgs stads hållbarhetskommunikation. Vidare undersöks hur hållbarhetsdiskuThe aim of this study is to increase the knowledge of how communicative standardisation between institutions upholds established notions about sustainable development in society. With a social constructionist approach, we analyse how sustainability discourses are constructed within the Agenda 2030, and if these discourses are reproduced in the sustainability communication of the city of Helsingbor

This thesis is a case study of the energy consumption of similar warehouses in different geographic locations. The purpose is to examine how to reduce the effect of the climate so that other parameters that control energy consumption in warehouse type buildings can be explored. Further the problem is explored with different organization that can come across such a problem. The rapport uses degree
