Arranging anisotropic nanoparticles into ordered assemblies remains a challenging quest requiring innovative and Ingenuous approaches. The variety of interactions present in colloidal solutions of nonspherical inorganic nanocrystals can be exploited for this purpose. By tuning depletion attraction forces between hydrophobic colloidal nanorods of semiconductors, dispersed in an organic solvent, the
A simple and available method is proposed for the synthesis of cobalt-containing nanoparticles. This method comprises cobalt formate thermolysis in hydrocarbon oil without extra stabilizing ligands. The size, composition, and structure of the nanoparticles are determined by transmission electron microscopy, X-ray powder diffraction, and electron diffraction. The average particle size is 10-14 nm.
Gold nanoparticles are very interesting because of their potential applications in microelectronics, optical devices, analytical detection schemes, and biomedicine. Though shape control has been achieved in several polar solvents, the capability to prepare organosols containing elongated gold nanoparticles has been very limited. In this work we report a novel, simplified method to produce long, th
This paper describes the synthesis of binary nanoparticles consisting of a noble metal and a magnetic component. These heterostructures were produced by a seeded-growth approach in aqueous solution. FePt nanoparticles, as the magnetic component, were first synthesized in an organic medium, subsequently transferred into water, and finally used as seeds for the growth of the noble metal Au. This pro
In 1985 the County Administrative Board of Jämtland initiated a process to protect Storsjöodjuret (the Great Lake Monster). As other famous cryptids, the Monster has become a valuable resource in the process of cultural heritage, marketing and tourism. We apply Bateson’s theories of play (1972) and Goffman’s concept of frame (1974) to show how play offers a metacommunicative strategy to circumvent
Synthesis of nanocomposites based on the low density polyethylene (LDPE) with homogeneous dispersion of CeO2 nanoparticles is reported.

Mellan åren 1955 och 1957 utförde Märta Strömberg (sedermera professor i arkeologi) och Rolf Petré (som senare blev fil. lic. i arkeologi) arkeologiska undersökningar av Vätterydsgravfältet i norra Mellby socken (L1990:1893 / Norra Mellby 1:1) ...
In this paper we conjecture combinatorial Rogers-Ramanujan type colored partition identities related to standard representations of the affine Lie algebra of type C(1) ℓ, ℓ ≥ 2, and we conjecture similar colored partition identities with no obvious connection to representation theory of affine Lie algebras.
T2D is the most widespread endocrine disease. In conventional stimulus secretion coupling increased blood glucose is metabolized causing an increased intracellular level of ATP and closure of the KATP channels, and this, in turn, depolarizes the cell membrane leading to the opening of voltage-gated Ca2+ channels, the influx of Ca2+ and exocytosis of insulin granules. This model has become almost a
Background and Objective: Waste in clinical trials remains rife. We developed an economic model to predict the cost of trials based on input costs, duration, power, number of sites, recruitment eligibility and consenting rates. Methods: We parameterised the model for three proxy placebo-controlled surgical trials using data from a systematic review, a bespoke cost survey, and from the literature.
Att träna samspel mellan politik och förvaltning kan vara en god idé efter val. Ett sätt att göra detta är att diskutera case tillsammans. Med utgångspunkt i forskning om styrning av offentlig sektor och case pedagogikens fördelar diskuterar författarna vad som kan underlätta eller försvåra förverkligandet av politiska beslutPracticing interaction between politics and administration can be a good idea after elections. One way to do this is to discuss cases together. Based on research on governance and control of the public sector and the advantages of case pedagogy, the authors discuss what can facilitate or hinder the realization of political decisions
Many organisms have separate sexes, i.e., males and females. The presence of separate sexes causes sex-specific selection regimes and sexual antagonism, which can lead to sex differences in morphology, physiology, and behaviours. Sex and sex differences can be genetically governed and regulated by a pair of sex chromosomes (e.g., X and Y, or Z and W), on which there often are regions without recom
Background: Asthma is associated not only with lower health-related quality of life (HRQL) but also with psychological health and insomnia. The aim of this study was to investigate associations between HRQL, asthma symptoms, psychological status and insomnia in adults from three Nordic countries. Methods: This study comprised 2,270 subjects aged 29-55 from Sweden, Iceland and Norway. HRQL was meas
This chapter theorises the postwar city in order to enable its study. It first theorises the postwar as not the given and linear transition from war to a universal and objective peace, but rather as permeated by conflicts over peace(s) in which heterogeneous and subjective peace(s) strive to socio-politically order society in diametrically different ways. The city is then theorised as constituted
This chapter employs governmentality on postwar Mitrovica (Kosovo) to understand how different governing attempts structure the field of possible acts for collectives in its urban conflicts over peace(s). The first line of analysis explores how Belgrade uses its parallel institutions—which encompass everything from healthcare and education to undercover police and criminal networks—to enable, enco
This chapter first argues that urban conflicts over peace(s) in the postwar city should be studied through the acts, governing, and spaces underpinning them. It then theorises negotiating agency, governmentality, and relational space as concepts apt for analysing these dimensions. Negotiating agency sees acts are the result of open-ended and constantly on-going negotiations between the subject and
This chapter employs negotiating agency on postwar Mostar (Bosnia-Herzegovina) to understand acts come about in its urban conflicts over peace(s). The first line of analysis uses a feature film about the city to explore the negotiation between Slavko (who wants to act in line with the coexisting peace) and a world that enforces the ethnonational—Bosniak and Croat—peace(s). The generated insights o
This chapter discusses how Shared Reading (SR) can be used as a method when teaching university students in professional education. Drawing on experiences from both the Medical School and the Creative Writing Program, the chapter shows how SR can be used to enhance professional development in two different settings. In Medical School, SR is used to create a space for exploration of relational and
