What controls variation in carbon use efficiency among Amazonian tropical forests?

Why do some forests produce biomass more efficiently than others? Variations in Carbon Use Efficiency (CUE: total Net Primary Production (NPP)/ Gross Primary Production (GPP)) may be due to changes in wood residence time (Biomass/NPPwood), temperature, or soil nutrient status. We tested these hypotheses in 14, one ha plots across Amazonian and Andean forests where we measured most key components o

Direct comparison between in vivo and in vitro microsized particle phagocytosis assays in Drosophila melanogaster

The effects of micro and nanoparticles on the innate immune system have been widely investigated and a general lack of agreement between in vivo and in vitro assays has been observed. In order to determine the origin of these discrepancies, there is a need for comparing the results of in vivo and in vitro phagocytosis assays obtained using the same particles and same immune cells. Here, we establi

Sex Chromosome Evolution in a Hermaphrodite : Genetic and phenotypic relationships between sex roles

Svensk sammanfattningAvhandlingens syfte har varit att studera utvecklingen av en könskromosom i realtid genom att simulera dess framväxt i en hermafroditisk plattmask i laboratoriet. Jag gjorde detta genom att selektera på dels honlig fitness (fitness via ägg), dels hanlig fitness (fitness via spermier) med hjälp av en genetisk markör, som agerade som en könsbestämmande gen. Detta ska efterlikna Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. Sexually antagonistic alleles are a type of genetic variation that increases fitness for one sex while being detrimental for the other sex. Recombination arrest around the SDR and gen

Proteolytic signatures define unique thrombin-derived peptides present in human wound fluid in vivo

The disease burden of failing skin repair and non-healing ulcers is extensive. There is an unmet need for new diagnostic approaches to better predict healing activity and wound infection. Uncontrolled and excessive protease activity, of endogenous or bacterial origin, has been described as a major contributor to wound healing impairments. Proteolytic peptide patterns could therefore correlate and

Early Electroencephalography Suppression and Postnatal Morbidities Correlate with Cerebral Volume at Term-Equivalent Age in Very Preterm Infants

Background: Early brain activity is associated with long-term outcome. Establishing a relation also with postnatal brain growth may increase our understanding of early life influences on preterm brain development. Objectives: The aim of this study was to investigate whether early electroencephalography (EEG) activity in infants born very preterm is associated with brain volumes at term, and whethe

Secular trends in sickness absence among Swedish patients with ankylosing spondylitis and psoriatic arthritis

The aim was to investigate whether secular trends in sickness absence (SA) were present in patients with ankylosing spondylitis (AS) and psoriatic arthritis (PsA) receiving their diagnosis between 2002 and 2011. A repeated cross-sectional study design was used. Patients were identified in the Skåne Healthcare Register (SHR). A washout period of 18 months was applied. The general population seeking

Comparison of Mortality and Nonfatal Cardiovascular Events in Adults With Atrial Fibrillation With Versus Without Levothyroxine Treatment

Levothyroxine has been suggested to be cardiotoxic, but previous studies on the risk of cardiovascular events associated with levothyroxine treatment have been inconclusive. We aimed to study the association between levothyroxine treatment and all-cause mortality as well as cardiovascular events. Study population included all adults (n = 12,283) ≥ 45 years diagnosed with atrial fibrillation (AF) a

‘Youth-friendly’ characteristics of professionals in mental health settings

Adolescents have a unique developmental vulnerability to suicide, with youth presenting as the second most vulnerable group to suicide across the lifespan. Youth have been recognized as underserved mental health service recipients, with only one in six of those in need receiving care. Calls for innovative mental health services to better serve youth have been articulated for over a decade and the

Searches for transverse momentum dependent flow vector fluctuations in Pb-Pb and p-Pb collisions at the LHC

The measurement of azimuthal correlations of charged particles is presented for Pb-Pb collisions at sNN=2.76 TeV and p-Pb collisions at sNN=5.02 TeV with the ALICE detector at the CERN Large Hadron Collider. These correlations are measured for the second, third and fourth order flow vector in the pseudorapidity region |η| < 0.8 as a function of centrality and transverse momentum pT using two obser

Population Growth and Job Creation in Timor-Leste

Timor-Leste began its independence as one of the poorest nations in the world. Substantial progress has been made thereafter but the challenges for future development are numerous. High population growth and modest growth of GDP means that per capita income is declining and that the extent of poverty is increasing. For this situation to change, income opportunities other than those provided by sub

Foreign Firms and Chinese Employment

This paper examines the effect of foreign direct investment (FDI) on employment in the Chinese manufacturing sector. As one of the world's largest recipients of FDI, China has arguably benefited from foreign multinational enterprises in various respects. However, one of the main challenges for China, and other developing countries, is job creation, and the effect of FDI on employment is uncertain.

Material selection - A qualitative case study of five design consultancies

This qualitative case study aims at understanding when and how industrial designers, working in design consultancies, engage in activities that will influence material selection in the design process. While the extant literature presents material selection processes as a sequence of activities aimed at finding candidate materials, there is paucity of research on material criteria activities. Formu

The language of freedom and slavery in tacitus agricola

The Agricola has long been a popular object of study for the connection that it makes between the British narrative of resistance against Roman domination and the Roman narrative of resistance against imperial domination. However, no agreement has been reached on the question of how exactly the two narratives 'affect' each other. Simultaneously, while it has often been remarked that Tacitus' langu

From economic choice to social choice in coastal management : A critical assessment of the use of cost-benefit analysis in the evaluation of an erosion control project in Flagler County, Florida, U.S.A.

Sustainable development remains of general interest in both political and academic circles. Importantly, the approach to collective decision making adopted in pursuit of sustainable development has importance repercussions regarding what range of possible informational considerations get incorporated as relevant to a given choice exercise. The most dominant approach to environmental public policy
