Anisotropic interactions in colloidal suspensions have recently emerged as a route for the design of new soft materials. Nonisotropic particles can form nematic, smectic, hexatic, and columnar liquid crystals. Although the formation of these phases is well rationalized when excluded volume is solely at play, the role of electrostatic interactions still remains unclear and even less so when particl

Medical X-ray imaging is the largest source of radiation exposure to the population from artificial sources. Computed tomography (CT) contributes with 50-80 % of that radiation. About 660 000 CT examinations (2005) are done in Sweden every year. A CT examination gives a mean effective dose of 5 mSv, which is about 10 times higher than for a corresponding conventional X-ray investigation. This pres

The lizard genus Egernia has been suggested as an excellent model system for examining the evolution of sociality as it exhibits considerable diversity in social organization both between and within species. To date the majority of work examining the factors responsible for the evolution of sociality within Egernia has advocated a broad scale approach; identifying the social structure of specific

The sentinel node biopsy (SNB) procedure is a multidisciplinary technique, invented to gain prognostic information in different malignant tumors. The aim of the present study was to study the cohort of patients with malignant melanoma, operated with SNB, from the introduction of the technique in Sweden, concerning the prognostic information retrieved and the outcome of the procedures. In Sweden al

Despite the fact that large welfare states are vulnerable to free-riding, the idea that universal welfare states lead to higher trust levels in the population has received some attention and support among political scientists recently. This paper argues that the opposite direction of causality is more plausible, i.e. that populations with higher trust levels are more prone to creating and successf

PURPOSE: To analyze reduction of intraocular pressure (IOP) by argon laser trabeculoplasty (ALT) in the Early Manifest Glaucoma Trial and factors influencing the effect of such treatment. DESIGN: Cohort study based on 127 patients from the treatment group of the Early Manifest Glaucoma Trial, a randomized clinical trial. METHODS: Patients randomized to the treatment arm of the Early Manifest Gla

In the early postwar period, improvements in life expectancy in many Western countries made health authorities, health scientists and politicians believe that social differences in mortality converged. The assumption was that inequality, when measured as death rates, was on steady decline, possibly even on the brink of disappearing. The question is then, how far back in time can social differences

New anatomical observations of the holotype skull of Plotosaurus bennisoni from the Maastrichtian Moreno Formation of California, U.S.A., are used as a framework to examine cranial kinesis in derived members of the Mosasaurinae. Enlarged posteromedial flanges of the frontal and extensive lateral contacts of the prefrontal and postorbitofrontal contributed to increased rigidity along the frontopari

In order to understand ritual in the past, archaeology has long relied on theories developed in other disciplines. While these theories, which often rely on written or oral information, have added many important dimensions to our interpretation of the archaeological record, they have often proven difficult to successfully articulate with the archaeological sources. Moreover, archaeology has tended

Even if outsourcing is a well-researched phenomenon, it can be stated that evaluation studies on IS outsourcing relationships are scarce. From a description of two IS outsourcing relationship cases, a set of les-sons learned are presented. A boundary spanning perspective is then used when evaluating these lessons learned in the client-supplier outsourcing relationships and thereby adding a “new” t

The Bologna process is a voluntary joint venture among 46 European countries, which has as its objective the creation of a European Higher Education Area (EHEA) by 2010. The EHEA will cover all of Europe including European Union newcomers Armenia, Azerbaijan, Georgia, Moldova, and Ukraine. Its aim is to allow for degrees and qualifications awarded in one country to be understood and recognized in

Environmental conditions, dispersal lags, and interactions among species are major factors structuring communities through time and across space. Ecologists have emphasized the importance of biotic interactions in determining local patterns of species association. In contrast, abiotic limits, dispersal limitation, and historical factors have commonly been invoked to explain community structure pat

Genetic predisposition for cardiovascular disease (CVD) is likely to be modified by environmental exposures. We tested if the associated risk of CVD and CVD-mortality by the single nucleotide polymorphism rs4977574 on chromosome 9p21 is modified by life-style factors.

A critical discussion of heritage politics and heritage studies

Building on a framework introduced by Chaney and Ossa (2013), we construct a task-based model of the firm’s choice of occupational inputs to examine how that choice varies with greater global engagement. We depart from Chaney and Ossa by assuming that more complex tasks are more costly to complete. Within the structure of our model, firms skew employment toward occupations engaged in more complex

Feather mosses utilize various sources of nitrogen (N): they absorb N deposited on leaf tissue, they host N-2 fixing cyanobacteria, and they are able to take up N directly from soil. In addition to their importance as primary producers in boreal ecosystems, feather mosses play a significant role in N cycling. However, estimates of their ability to take up N from soil in situ are scarce. Further, c

Obesity is a well-established risk factor for colorectal cancer (CRC), and accumulating evidence suggests a differential influence of sex and anthropometric factors on the molecular carcinogenesis of the disease. The aim of the present study was to investigate the relationship between height, weight, bodyfat percentage, waist- and hip circumference, waist-hip ratio (WHR), body mass index (BMI) and
