Spectroscopic studies have demonstrated that nearly all Galactic globular clusters (GCs) harbour multiple stellar populations with different chemical compositions. Moreover, colour-magnitude diagrams based exclusively on Strömgrem photometry have allowed us to identify and characterise multiple populations along the RGB of a large number of clusters. In this paper we show for the first time that S

Popular Abstract in Swedish PAX FÖR MANETER! Evolutionen är den process som format det liv vi ser omkring oss. Ända sedan Darwins tid har man känt till att arter och djurgrupper uppstår genom att det finns en variation mellan individer och att då tillgångarna begränsas (såsom mat eller utrymme) blir det de bäst anpassade som överlever och fortplantar sig. Flercelliga djur har funnits på jorden i kDuring the course of evolution animal complexity and diversity is generated. The last couple of years it has become increasingly clear that morphologically diverse animals share a great deal of their genomic contents, and it must be the expression of regulatory genes in new setting, rather than the generation of new genes, that are fundamental for the generation of diversity. Basal phyla hold a ke

Impacted, morselized bone allografts are used with good clinical results in revision of hip prostheses with loosening and osteolysis. The impacted bone graft appears radiographically to remodel, but histological analyses have shown a heterogeneous picture with a mixture of living and dead bone. Thus, complete remodeling of the graft may be neither a prerequisite nor a cause of the good clinical re

The authors retrospectively studied 43 patients suspected of having internal hemorrhoids at double-contrast barium enema examination. At endoscopy, 24 patients (56%) had internal hemorrhoids, four (9%) had other pathologic lesions in the rectum without evidence of hemorrhoids, and 15 (35%) had no reported abnormalities in the rectum. Internal hemorrhoids were found at endoscopy in 10 of 20 patient

The EU Blue Growth agenda is being implemented at a time when European coastal fisheries and traditional fishing communities are struggling to survive or have already vanished from areas where they used to flourish. Driven by the strong conviction that current disadvantaged and vulnerable coastal fishers still have a central role to play in rural development, local level initiatives are calling fo

The objective of this paper is to build a model of how tacit knowing is externalised and becomes reflected external knowledge. Knowledge Management (Nonaka, 1991, 1994; Nonaka, Toyama, & Konno, 2000) is an important field in Business Administration. Based on the model provided by Nonaka and his colleagues (Nonaka, 1994; Nonaka & Takeuchi, 1995; Nonaka et al., 2000) researchers and practiti

The past years have seen an unprecedented growth in the ICT economy that has fundamentally altered business models and consumer cultures. Many of the changes this has implied are specifically relevant for tourism, a sector that perhaps more than any other is exposed to and implicated in digital innovation, consumer-business interrelationships, and platform reliance. Most studies of the digitalizat

Typhoon Haiyan hit the Philippines on 8th November 2013 destroying more than 1 million houses and affecting mostly the poor. This paper discusses user involvement in housing recovery from a capability perspective. The paper also analyses possibilities for extension of the housing solutions. Based on the Sphere handbook and the theoretical framework, a Model for user involvement in evolutionary hou

Affluent blood flow through a complicated net of vessels supplies skeletal bone tissue with oxygen and nutrients. Due to accidental events or physiological processes, the blood supply might be deficient or even disrupted, and the healthy bone decays in a process that, for the hip location, is denoted as osteonecrosis of the femoral head (ONFH) or avascular femoral head necrosis. Early diagnosis is

The first model to predict chloride ingress into concrete was presented by Collepardi in 1970, in Italian! That model was used for some 20 years for design of concrete structures before it was realized that the main parameter, the apparent chloride diffusion coefficient, is not a material property! Since then the Collepardi model has been significantly improved and developed into more or less soph

Society is becoming increasingly dynamic and complex, and therefore more vulnerable. It is thus important that society is resilient in order to be able to protect citizens and critical functions in the wake of disasters. It has been suggested that disaster risk reduction (DRR) is key in establishing resilience, and that adequate capacity in DRR is vital to reduce the effects of disasters. DRR and
