OBJECTIVE: A prenatal diagnosis of the fetus for a mother of two previously deceased infants who died from the recently described autosomal recessive disease (OMIM 603358). The infants presented with intrauterine growth retardation, aminoaciduria, cholestasis, iron overload, severe lactic acidosis, and early death (GRACILE syndrome). STUDY DESIGN: DNA was extracted from the fibroblasts and tissue
The effect of the presence of water vapor on the reduction of nitric oxide with ammonia was investigated using vanadia on SiO2-TiO2 as a catalyst. The selectivity towards nitrogen is greatly increased upon addition of water. Repeated use at temperatures of 825 K causes sintering of the catalyst and loss of activity as well as selectivity towards nitrogen. The formation of nitrous oxide is preferen
Popular Abstract in Swedish Många material som ingår i tillverkade varor har kvar sina kvaliteter även när varorna är uttjänta. Men bara en liten del av dessa material återvinns idag på ett sätt som gör det möjligt att återanvända materialet för samma syfte och med bevarade egenskaper. I allmänhet har det industriella samhället fortsatt att praktisera en slit- och slängmentalitet, trots att det beMany anthropogenically-produced or beneficiated materials contained in “end-of-life” products retain a great proportion of the invested manufacturing work when discarded. Very few such materials are reconstituted and applied in new products at the same material inherent quality level as in their first lifetime – a process known as “closed-loop recycling”. In general, industrial society maintains a
The effect of pixel size on shape determination in screening digital mammography systems was studied using a shape identification task as the measured outcome. Ten microcalcifications on screen-films were digitised to a range of pixel sizes (2.5-200 μm) and extracted from computed radiography (CR) images (50 μm) acquired under equivalent imaging conditions. Fifteen observers attempted to identify
As shown in a companion paper the geometrical diameter of a hair strand is an important parameter for quantification of its trace element content after PIXE analysis. By analysing Rutherford backscattered protons simultaneously with PIXE analysis a reliable estimate of the hair diameter can be obtained. In this work the hypothesis that there exists a linearity between the geometrical diameter and
Distributions of tumor necrosis factor (TNF) and its soluble receptor forms, R55-BP and R75-BP, were analyzed in the cerebrospinal fluid of patients with severe acute or chronic central nervous system infections. Tuberculous infections were associated with high ratios of R55-BP and R75-BP to TNF, 27.2 and 28.0, respectively, suggesting a small biologically active fraction of TNF. The opposite was
Objectives: To describe the physiological properties of the peritoneal membrane in adult patients treated with peritoneal dialysis (PD) and to analyze the effects of patient characteristics and time. Design: Observational study. Setting: Department of Nephrology at the Sahlgrenska University Hospital. Method: Peritoneal function was analyzed by the Personal Dialysis Capacity (PDC) test, based on t
Residual masses are frequently found in patients with aggressive lymphomas, following therapy. A study was undertaken to determine whether initial tumour size, changes during treatment, or size of the residual mass could provide prognostic information. Computed tomography (CT) examinations were carried out before, midway and after completion of chemotherapy in 37 patients with aggressive lymphoma
Diabetic nephropathy is a common complication in diabetes mellitus. In addition to the risk of renal failure, patients with established nephropathy are at increased risk of proliferative retinopathy and cardiovascular disease. As the earliest prodrome of nephropathy is microalbuminuria, albumin excretion needs to be monitored with a reliable method in all diabetics. In the event of microalbuminuri
We consider an exhaustive polling system with three nodes in its transient regime under a switching rule of generalized greedy type. We show that, for the system with Poisson arrivals and service times with finite second moment, the sequence of nodes visited by the server is eventually periodic almost surely. To do this, we construct a dynamical system, the triangle process, which we show has even
Popular Abstract in Swedish Modellering och simulering är etablerade tekniker för att lösa designproblem inom många olika ingenjörsdiscipliner idag. Dedicerade språk, såsom Modelica, och effektiva mjukvaror finns också tillgängliga. I denna avhandling presenteras en språklig utvidgning av Modelica, Optimica, som är avsedd för formulering av dynamiska optimeringsproblem. För att demonstrera användnModeling and simulation are established techniques for solving design problems in a wide range of engineering disciplines today. Dedicated computer languages, such as Modelica, and efficient software tools are available. In this thesis, an extension of Modelica, Optimica, targeted at dynamic optimization of Modelica models is proposed. In order to demonstrate the Optimica extension, supporting sof
It is of increasing importance to develop efficient purification methods for recombinant proteins where the number of steps can be minimised. The aim has been to establish a method for predicting the partitioning of the wild-type target protein in an aqueous two-phase system, and with this as basis, develop fusion tags and optimise the phase system for enhanced partitioning of the target protein.
Spatial heterogeneity of hydraulic and sorptive processes may have a strong impact on the mobility of bacteria in porous soils. Whereas heterogeneity at the microscopic solid particle/interstitial pore scale has been conceptually addressed by dividing the porous material into two or more coexisting sorbing fractions, field-scale spatial variability has been approached by developing stochastic meth
Drawing on T. H. Marshall, the notion of social citizenship is applied in this article to the development of public care for the elderly in Sweden. Initially a historical résumé clarifi es the change of elder care in Sweden as a move from a residual arrangement with its roots in the poor laws of the nineteenth century to become, during the 1960s and 1970s, an institutionalized public s ervice c om
Byggnadsrelaterade faktorer påverkar innemiljön och brukarens upplevelse av innemiljön i form av hälso- och komfortbesvär. De viktigaste innemiljöområdena är enligt tidigare gjord kunskapssammanställning är termiskt klimat, luftkvalitet samt ljud- och ljusmiljön. Syftet med uppsatsen är att undersöka följande hypotes i en fallstudie: ”Brukare av kvalitetsmärkta nya byggnader upplever sin innemilThe purpose of this licentiate thesis is to investigate the following hypothesis in a case study: “Occupants of buildings with a quality labeled indoor Environment experience a better indoor environment than occupants of buildings with normal planning and construction.” The aim of the case study is to compare the outcome of using a quality system for indoor environment with a normal quality system
Popular Abstract in Swedish I avhandlingen utvecklas en begreppsapparat som syftar till att utvidga vetenskapens möjligheter att studera människors formaliserade praktik i såväl religiösa som profana sammanhang. Begreppet ritual blir en term att se och tänka med. Författaren applicerar sin begreppsapparat på de medeltida isländska släktsagorna där skapandet av allianser mellan personer är ett viktTo make it possible to classify an action as a ritual act we need to know exactly what constitutes it. In this thesis I try, with the aid from literature of the field called ritual studies and the sagas of Icelanders, to sort out what these constituent elements best should consist of if we want to use the term ritual as an analytical tool in the production of knowledge with scientific criteria.
