High uncertainties are common in detailed quantification of the N budget of agricultural cropping systems. The process-based CoupModel, integrated with the parameter calibration method known as Generalized likelihood uncertainty estimation (GLUE), was used here to define parameter values and estimate an N budget based on experimental data from an organic farming experiment in south-west Sweden. Da
Popular Abstract in English Research has shown the Ugandan construction industry to be, primarily, an informal sector dominated by unskilled labour contracted mainly on minor building works such as alterations and renovations. Within such a context, the industry has also received negative publicity due to increasing quality failures on sites – commonly referred to as shoddy work. Some reasons citeResearch has shown the Ugandan construction industry to be, primarily, an informal sector dominated by unskilled labour contracted mainly on minor building works such as alterations and renovations. Within such a context, the industry has also received negative publicity due to increasing quality failures on sites – commonly referred to as shoddy work. Some reasons cited for these failures include
The World Health Organization has a standardized tool to assess surgical capacity in low- and middle-income countries (LMICs), but it is often resource- and time-intensive. There currently exists no simple, evidence-based measure of surgical capacity in these settings. The proportion of cesarean deliveries in regard to the total operations (C/O ratio) has been suggested as a way to assess quickly
We study the mechanical failure of cemented granular materials (e.g., sandstones) using a constitutive model based on breakage mechanics for grain crushing and damage mechanics for cement fracture. The theoretical aspects of this model are presented in Part I: Tengattini et al. (2014), A thermomechanical constitutive model for cemented granular materials with quantifiable internal variables, Part
Technology foresight studies have become an important tool in identifying realistic ways of reducing the impact of modern energy systems on the climate and the environment. Studies on the future cost development of advanced energy technologies are of special interest. One approach widely adopted for the analysis of future cost is the experience curve approach. The question is, however, how robust
Freshwater blooms of cyanobacteria (blue-green algae) in source waters are generally composed of several different strains with the capability to produce a variety of toxins. The major exposure routes for humans are direct contact with recreational waters and ingestion of drinking water not efficiently treated. The ultra high pressure liquid chromatography tandem mass spectrometry based analytical
This study examined mortality and predictors of death in 1,396 primary amphetamine users (85% males) who were interviewed with the Addiction Severity Index in the Swedish criminal justice system during 2000-2006 and followed through 2008. Forty-nine clients deceased (standardized mortality ratio 4.1 [3.0-5.4]), at least 84% of deaths were violent or drug-related (12% suicides), and Cox regression
Aims: The aim of this study was to determine the incidence of neonatal morbidity in extremely preterm infants and to identify associated risk factors. Methods: Population based study of infants born before 27 gestational weeks and admitted for neonatal intensive care in Sweden during 2004-2007. Results: Of 638 admitted infants, 141 died. Among these, life support was withdrawn in 55 infants becaus
Background: In juvenile idiopathic arthritis (JIA), the trend towards early therapeutic intervention and the development of new highly effective treatments have increased the need for sensitive and specific imaging. Numerous studies have demonstrated the important role of MRI and US in adult rheumatology. However, investigations of imaging in JIA are rare, and no previous study has been comparing
In this study doctoral students in psychology and social anthropology/ethnology were interviewed as to their selection of research problem for their Ph.D. thesis. From the perspective of activity theory it is suggested that the research problem can profitably be seen as the object of activity in research. Graduate students’ selection of a research problem was analyzed as a process occurring over t
Background Primary hyperparathyroidism (pHPT) is associated with an increased mortality attributable to cardiovascular disease (CVD), suggested to be alleviated by surgery. The exact mechanism of the beneficial influence of parathyroidectomy on survival is unknown. Furthermore, studies suggest that there is no increased mortality compared to the mortality rate in the general population during rece
Maternal intrauterine enterovirus infection during pregnancy increases the risk for the offspring to develop type 1 diabetes mellitus. Type 1 diabetes mellitus and autoimmune thyroiditits (AIT) are closely linked. A common pathogenetic factor is possible. The objective of this study was to investigate a possible association between maternal enterovirus infection during pregnancy and the developmen
n the current study, we address the underlying mechanism for the selective generation of gut-homing T cells in the gut-associated lymphoid tissues (GALT). We demonstrate that DCs in the GALT are unique in their capacity to establish T cell gut tropism but in vivo only confer this property to T cells in the presence of DC maturational stimuli, including toll-like receptor-dependent and -independent
The possibility of using pervaporation for the recovery of natural aroma compounds in the food industry has been widely recognised. The aim of this study was to build a bridge between experimental studies of multi-component systems and potential applications of pervaporation in the food industry. Therefore, a novel process simulation of pervaporation has been developed for multi-component mixtures
The first stories about Kluskap, the culture hero of the Mi’kmaq in eastern Canada, were written down at the end of the 19th century. The romantic epoch and the environmental failures of industrialism had generated a growing interest for the “Indian”, who seemed to inherit the continent’s authentic “poetry of the Volk” and harbour deep wisdom about nature. The first written literature about Kluska
A calculation scheme with significant modifications and improvements for determining the ionization balance and the ion temperature evolution in an electron beam ion trap (EBIT) is presented. The scheme is applied to thorium, tantalum and oxygen ions using a specific set of EBIT operating parameters. The results of the calculation are compared to experiment and previous calculations. Rates for the
Objective: Pain measurement is a necessity in pain treatment but can be difficult in young children. The aim of this study was to evaluate the validity and reliability of the Behavioural Observational Pain Scale (BOPS) as a postoperative pain measurement scale for children aged 1-7 yrs. The scale assesses three elements of pain behaviors: facial expression, verbalization, and body position. Design
An integrated process for purifying a 6.1 kilo base pair (kbp) plasmid from a clarified Escherichia coli cell lysate based on an ultra/diafiltration step combined with polymer/polymer aqueous two-phase system and a new type of chromatography is described. The process starts with a volume reduction (ultrafiltration) and buffer exchange (diafiltration) of the clarified lysate using a hollow fibre me
We outline here a simple method to prepare polymeric surfaces of controlled surface topography on the micrometer scale, via assembly and arrest of microgel particles, for use in a range of biological applications to modify cell adhesion and spreading. In previous work by other groups, it has transpired that topography on the nanoscale is unlikely to be useful for this purpose, as roughness on this
