Determining accurate rates of benthic nitrogen (N) removal and retention pathways from diverse environments is critical to our understanding of process distribution and constructing reliable N budgets and models. The whole-core 15N isotope pairing technique (IPT) is one of the most widely used methods to determine rates of benthic nitrate-reducing processes and has provided valuable information on
BACKGROUND: Many countries lack sufficient medical doctors to provide safe and affordable surgical and emergency obstetric care. Task-sharing with associate clinicians (ACs) has been suggested to fill this gap. The aim of this study was to assess maternal and neonatal outcomes of caesarean sections performed by ACs and doctors. METHODS: All nine hospitals in Sierra Leone where both ACs and doctors
I kapitlet diskuteras vilka litteraturhistoriska föreställningar om arbetarlitteratur som styr dagens svenska arbetarlitteratur. Dagens varianter skildrar i stor utsträckning samhällets trasproletariat och tycks därmed ha mer gemensamt med exempelvis Maksim Gorkijs noveller från 1890-talet än med trettiotalets klassisk-kanoniska svenska arbetarskildringar. Hur kan det komma sig? Vad säger denna li
The selection pressures that drive flight feather morphology are poorly understood. Using a phylogenetic comparative approach and data from 178 species of birds, we investigated whether both position along the wing length and flight feather length affected vane structure. We found that barb density was lower on distal primaries than on proximal primaries of the leading feather vane. In contrast, oThe selection pressures that drive flight feather morphology are poorly understood.

The exegetical subjects have a particular interdisciplinary role within academia, implying that their responsibilities and significance are – and should be – under constant debate. In his article, church historian Joel Halldorf, argues for the overt use of theological interpretations (in the narrow sense of "normative theology") in the exegetical discipline.

Central sensitization is a condition in which there is an abnormal responsiveness to nociceptive stimuli. As such, the process may contribute to the development and maintenance of pain. Factors influencing the propensity for development of central sensitization have been a subject of intense debate and remain elusive. Injury-induced secondary hyperalgesia can be elicited by experimental pain model
Aim: To study health-related quality of life (HRQoL) in children with idiopathic clubfoot (IC) and the influence of sex, clubfoot laterality and neurodevelopmental difficulties (NDD) on HRQoL. Methods: A cross-sectional questionnaire-based study in Stockholm and Skåne Counties, Sweden, of 106 children with IC born 2004–2007 (mean 9.4 ± 0.6 years) and a general population sample of 109 schoolchildr
Today, more than ever, ‘Spaceship Earth’ is an apt metaphor as we chart the boundaries for a safe planet1. Social scientists both analyse why society courts disaster by approaching or even overstepping these boundaries and try to design suitable policies to avoid these perils. Because the threats of transgressing planetary boundaries are global, long-run, uncertain and interconnected, they must be
This work evaluates the performance and emissions of the series hybrid vehicle concept powered by a gasoline partially premixed internal combustion engine. To do so, experimental data was collected from a Volvo VED-D4 Euro 6 four-cylinder compression ignition engine running under gasoline partially premixed combustion. Two series hybrid vehicle models were developed in GT-Power®, which were fed wi
Abstract in Undetermined This paper deals with limitations on control system performance due to load disturbances, measurement noise, actuator saturation and system dynamics. Simple problems which capture the essence of the problem are formulated and solved. The results make it possible to quickly explore a design problem for preliminary assessment before attempting to do massive computations.

One aspect of tombs and burials in the BA Aegean in general that has not received much notice is that of color (hue and shine). Were certain hues more predominant than others? Was this significant? Was the presence (or absence) of shine of importance? Following a discussion of ‘what is color?’, the study and results of the colors of the finds from Late Bronze Age tombs at three sites in the Greek
The linear quadratic optimal control problem under quadratic constraints is an optimization problem over a generally non-convex set. Yakubovich [8] and Megretski [4] have studied this problem, and they show how it may be translated into a two-stage, convex optimization problem. In this paper we study the linear quadratic control problem under quadratic constraints for generalized first-order syste
Using satellite remote sensing data for observing vegetation seasonality is an important approach to estimate phenology and carbon uptake of land vegetation. The successful launch of Sentinel-2B in 2017 initiated full operation of the Sentinel-2 twin satellites, and they now provide 10 - 60 m spatial resolution satellite data at 5 days temporal resolution worldwide, releasing approximately 3.2 TB
OBJECTIVE: To assess health-related quality of life (HRQOL) in a large multicenter cohort of children and young adults with Marfan syndrome participating in the Pediatric Heart Network Marfan Trial.STUDY DESIGN: The Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core Scales were administered to 321 subjects with Marfan syndrome (5-25 years). PedsQL scores were compared with healthy popul
