Species integrity can be challenged, and even eroded, if closely related species can hybridize and produce fertile offspring of comparable fitness to that of parental species. The maintenance of newly diverged or closely related species therefore hinges on the establishment and effectiveness of pre- and/or post-zygotic reproductive barriers. Ecological selection, including predation, is often pres
In this study, a phosphorus (P) module containing the biogeochemical P cycle has been developed and integrated into the forest ecosystem model ForSAFE. The model was able to adequately reproduce the measured soil water chemistry, tree biomass (wood and foliage), and the biomass nutrient concentrations at a spruce site in southern Sweden. Both model and measurements indicated that the site showed s
Gunnarsson highlights how dialectics can shed light on the relation between love and dominance, foregrounding the crucial role that ontological tensions play in self–other relating. Drawing on Roy Bhaskar’s dialectical critical realist philosophy, she expands on Jessica Benjamin’s analysis of male dominance, as well as other feminist work, and elaborates on the necessity of living-with rather thanGunnarsson highlights how dialectics can shed light on the relation between love and dominance, foregrounding the crucial role that ontological tensions play in self–other relating.

Northern ecosystems are experiencing some of the most dramatic impacts of global change on Earth. Rising temperatures, hydrological intensification, changes in atmospheric acid deposition and associated acidification recovery, and changes in vegetative cover are resulting in fundamental changes in terrestrial-aquatic biogeochemical linkages. The effects of global change are readily observed in alt
Soil and water acidification was internationally recognised as a severe environmental problem in the late 1960s. The interest in establishing “critical loads” led to a peak in weathering research in the 1980s and 1990s, since base cation weathering is the long-term counterbalance to acidification pressure. Assessments of weathering rates and associated uncertainties have recently become an area of
The Arctic has warmed more than twice as fast as the global average since the late twentieth century, a phenomenon known as Arctic amplification (AA). Recently, there have been considerable advances in understanding the physical contributions to AA, and progress has been made in understanding the mechanisms that link it to midlatitude weather variability. Observational studies overwhelmingly suppo
Dissolved organic carbon (DOC) plays a key role in linking terrestrial and aquatic carbon cycles. Most of the work on soil and water DOC has been conducted in temperate watersheds. There is still a gap in knowledge on DOC dynamics within the tropics. This study assesses water extractable organic carbon (WEOC) in topsoils and describes the relationship between WEOC and land use/land cover (LULC), s
Purpose-The purpose of this paper is to address the issue of supply management coordination among a prominent contact lens company (customer), its carton supplier (first tier), and paperboard supplier (second tier). Adopting concepts within the theory of swift and even flow, the authors integrate the physical (material) and information flow among these supply partners to ensure higher productivity
Despite emergency and essential surgery and anaesthesia care being recognised as a part of Universal Health Coverage, 5 billion people worldwide lack access to safe, timely and affordable surgery and anaesthesia care. In Tanzania, 19% of all deaths and 17 % of disability-adjusted life years are attributable to conditions amenable to surgery. It is recommended that countries develop and implement N
PURPOSE: Major hurdles in oXHTx are the delayed xenograft rejection, the early perioperative cardiac xenograft dysfunction (PCXD) and the pig heart overgrowth, which were solved in this study with a costimulation blockade, a new non-ischemic cold preservation and a growth inhibition by anti-proliferative drugs. Aim was to achieve a 90-days-survival of minimal 60% (6 of 10 baboons) in this life-sup
Background: The present study aimed to examine the reliability and validity of the Italian version of the Autism Spectrum Disorder in Adults Screening Questionnaire (ASDASQ), a screening tool for autism spectrum disorder (ASD) among psychiatric outpatients. Methods: We recruited 340 subjects via an outpatient psychiatric service in Italy. Forty-eight had a diagnosis of ASD, confirmed after a compr
The focal company in this study is establishing a partnership style of’ relationships with a few selected suppliers. The article focuses on the driving forces behind such an initiative. It attempts to answer the questions why this company is trying to develop a closer working relationship with one of the selected suppliers, the supplier of corrugated board. The purpose of the article is thus to an
Popular Abstract in Swedish Att vatten är en otroligt viktig vätska för allt liv på jorden känner de flesta till; exempelvis består över hälften av människokroppen av vatten, och 70 procent av jordens yta är täckt av det. Att just denna till synes enkla kemikalie, vars molekyler består av två väteatomer och en syreatom, har en sådan unik betydelse är ingen slump, utan beror på att vatten har en raFluids composed of dipolar molecules are ubiquitous in nature, with water being the most prominent example. Due to their great importance and large complexity, a basic scientific understanding of the structure and thermodynamics of polar fluids is essential. In this thesis, simple polar model fluids are investigated with the aim of adding a bit to this understanding. In particular, the topics addr
Wetlands are often constructed to counteract eutrophication or brownification of downstream waters, although our understanding of their differences in efficiency and effects is still scarce. Therefore, we here used the upper and lower 95% confidence limits of the average retention capacity of 11 wetlands to represent efficient and inefficient wetlands, respectively. We then modelled future scenari
The spatial distribution pattern of jobs and housing plays a vital role in urban planning and traffic construction. However, obtaining the jobs-housing distribution at a fine scale (e.g., the perspective of individual jobs-housing attribute) presents difficulties due to a lack of social media data and useful models. With user data acquired from a location-based service provider in China, this stud
The purpose of this report is to evaluate the fire safety in the commercial center Gränby. The project has been carried out as a part of the student’s education. The bases for the evaluation are three fire scenarios which have strategically been placed in the commercial center. The scenarios are simulated in the fire modeling program CFAST. The results have been analyzed and implemented in the egr
Successful innovation strategy relies on experience gained from a complexity of understanding, anticipating and managing the global business environment. But, although much research has examined strategies of private sector organizations in Western economies, there are relatively few studies of innovation in public sector organizations of transitional and protected economic environments, such as I
The aim of this project was to investigate how the properties of high expansion foam is affected when filling large enclosures using portable foam generators. The properties are investigated both by collecting the Swedish rescue services experiences on the matter through a survey and by five full scale tests. The main conclusions of the project is the impact which the amount of openings have on th
The science of decision making is studied in many areas of science and engineering, for example within, computer science, automatic control theory, mathematics and neurophysiology. The aim of this text is to provide a very brief overview of some of the models and tools used within mathematical decision making. These models can be studied in terms of an agent that observes the world and takes decis
