The ontogeny of the pelturine olenid trilobite Leptoplastides salteri (Callaway, 1877) from the Shineton Shales, Shropshire, England, was first described in 1925 by Frank Raw. Since that time, scanning electron microscopy and other new technologies have revealed many more details of structure, of early developmental stages in particular, than were available to Raw. Whereas protaspides are not pres

This article presents two case studies, which are the result of the application of a gendered interpretative tool to the collections at the Victoria & Albert Museum (London) and the Vasa Museum (Stockholm). Objects and their gendered narratives within the museums’ collections were researched across their lifecycle, from commission and manufacture to consumption and display in a museum setting.

The adsorption of proteins is a very common phenomenon, happening almost always when a protein solution comes into contact with a solid. However, it is far from always clear what the results of adsorption will be in terms of adsorbed amount, protein orientation, and protein conformation. In this work, the adsorption of two proteins – histatin 5 and fibrinogen – has been studied using coarse-graineThe adsorption of proteins is a very common phenomenon, happening almost always when a protein solution comes into contact with a solid.

Abdominal and general adiposity are independently associated with mortality, but there is no consensus on how best to assess abdominal adiposity. We compared the ability of alternative waist indices to complement body mass index (BMI) when assessing all-cause mortality. We used data from 352,985 participants in the European Prospective Investigation into Cancer and Nutrition (EPIC) and Cox proport

Moth wings are densely covered by wing scales that are assumed to specifically function to camouflage nocturnally active species during day time. Generally, moth wing scales are built according to the basic lepidopteran Bauplan, where the upper lamina consists of an array of parallel ridges and the lower lamina is a thin plane. The lower lamina hence acts as a thin film reflector having distinct rMoth wings are densely covered by wing scales that are assumed to specifically function to camouflage nocturnally active species during day time.

Categorising people and housing situations is unavoidable in research and national and local statistics on homelessness, as well as in regulating and planning for interventions and supply and allocation of suitable accommodation. Despite different motives and original functions, however, these categories and the use of them are influenced by the political discourse, especially when they travel froCategorising people and housing situations is unavoidable in research and national and local statistics on homelessness, as well as in regulating and planning for interventions and supply and allocation of suitable accommodation.

The Partition of India and Pakistan in 1947 divided the western Himalayan region of Baltistan in two parts. Being subject to internal colonization and nation-making by the two postcolonial nation-states, the Balti community, like many other communities in the Himalayan region, has recently voiced demands of self-rule and experienced a cultural revival. The situation in Baltistan is here seen throu

In the evolution of bird migration, partial migration is assumed to be an important intermediate step between migration and residency. Partial migration is characterised by the existence of both migratory and resident individuals in a given population. Compared to regular migration, relatively little is known about partial migrants and their migratory performances. In my thesis, I have studied th

Popular Abstract in Swedish Avhandlingen har flera uppgifter, som på olika sätt hör ihop. Den första uppgiften går ut på att undersöka samvetskonflikter i det svenska samhället. I denna typ av konflikt är samvete och samvetsfrihet centrala begrepp och de är viktiga för att förstå och ta ställning i konflikterna. Den andra uppgiften blir därför att undersöka och förstå begreppet samvete och ge ett The aim of this study is to describe and analyse four conflicts and two concepts. Four conflicts of conscience found in Swedish society are studied in the second chapter. 2.2 - the state’s requirement that all male citizens do military service and the citizen’s right to refuse to do military service. 2.3 - obligatory course requirements and the college student’s right to refuse participation in c

Immediate and long-term microvascular effects of chondroitinase ABC, 200 unit/ml, were analyzed in ten hamsters. The immediate effects on the microcirculation were studied by vital microscopy following local injection in the cheek pouch. There were no detectable effects on the microvascular blood flow during the 60 minutes of observation for chondroitinase ABC or the control. A therapeutic concent

In a recent paper we presented a procedure for optimal analyticalcontrol of several deformable mirrors based on only the measured guidestar wavefronts. The expected performance was evaluated for variousguide star configurations using up to three deformable mirrors. Forsimplicity the guide stars were assumed to be infinitely distant. Inthis paper we address the effect of using laser guide stars in

Inspections are widely used in the software engineering community as efficient contributors to reduced fault content and improved product understanding. In order to measure and control the effect and use of inspections, the fault content after an inspection must be estimated. The capture-recapture method, with its origin in biological sciences, is a promising approach for estimation of the remaini

Polyhydroxyalkanoates (PHAs) are considered good candidates in replacing commercial petrochemical plastics in certain applications like single-use packaging since they are biodegradable, biocompatible and share similar properties with conventional plastics. PHA synthase (PhaC) is the key enzyme in PHA biosynthesis. There are four classes of PhaC, namely, class I, class II, class III and class IV,

Partially premixed combustion (PPC) is a promising way to achieve high thermal efficiency and low emissions, especially by using multiple injection strategies. The mechanisms behind PPC efficiency are still to be explained and explored. In this paper, multiple injections have been used to affect the gross indicated efficiency in an optical PPC engine modified from a Volvo MD13 heavy-duty diesel en

PURPOSE:: To describe riboflavin and ultraviolet light (UV) collagen crosslinking as an effective treatment for infectious keratitis. METHODS:: A 25-year-old previously healthy female contact lens user was diagnosed with unilateral severe keratitis with unclear pathogenesis, although the clinical presentation suggested acanthamoeba as the infectious agent. A 4-mm diameter, annular, semi-opaque inf

In the cell, stalled ribosomes are rescued through ribosome-associated protein quality-control (RQC) pathways. After splitting of the stalled ribosome, a C-terminal polyalanine 'tail' is added to the unfinished polypeptide attached to the tRNA on the 50S ribosomal subunit. In Bacillus subtilis, polyalanine tailing is catalyzed by the NEMF family protein RqcH, in cooperation with RqcP. However, the

The present research front of NbO2 based memory, energy generation, and storage thin film devices is reviewed. Sputtering plasmas contain NbO, NbO2, and NbO3 clusters, affecting nucleation and growth of NbO2, often leading to a formation of nanorods and nanoslices. NbO2 (I41/a) undergoes the Mott topological transition at 1081 K to rutile (P42/mnm), yielding changes in the electronic structure, whThe present research front of NbO2 based memory, energy generation, and storage thin film devices is reviewed.

We present new estimates of the living standards among the rural labouring classes in Sweden from 1750 to 1900. Starting with a database of more than 1,000 probate inventories of rural, landless and semi-landless people from the years 1750, 1800, 1850 and 1900, we study the development for crofters in particular. In a sub-sample of 120 probate inventories we map in great detail the material items

The Academic Profession in Swedish HigherEducation: Continuity and Change in the New CenturyThe purpose of this article is to describe the composition and internal stratification of the university teaching staff at Swedish higher education institutions. We show that four fault lines shape the higher education field in the 21st century. These are, firstly, the resource hierarchies both between old
