Observations of the ultra-sharp-lined, chemically peculiar star chi Lupi taken by the Goddard High Resolution Spectrograph in echelle mode are presented. Thirty-six intervals of the spectral region between 1249 and 2688 Angstrom are covered with resolving powers in the range 75,000-93,000. Line identifications are provided, and the observed spectra are compared with synthetic spectra calculated us

The overall aim of this work was to increase our knowledge of newborn infants and their mothers, gain a better understanding of attachment and the infants' development and identify infants at risk for poorer emotional, social and cognitive development. An interdisciplinary approach was used. Six studies are included in the thesis. Non-nutritive sucking (NNS) and its relation to neurobehavioural st

Popular Abstract in Swedish Fall och frakturer hos äldre är ett vanligt förekommande och ökande hälsoproblem, som orsakar fysiska, sociala och psykologiska problem hos den enskilde och är kostsamt för samhället. Syftet med avhandlingen är att undersöka fallolyckor bland de patienter i åldern 65-74 år som kommit till ortopedklinikens akutmottagning, att undersöka reliabiliteten beträffande gångtestFalls and fractures in older people are a common and increasing health problem which causes physical, social and psychological problems for the individual and is costly to society. The aims of this thesis were to investigate accidental falls of patients aged 65 - 74 who attended an orthopedic emergency ward, to investigate reliability of the modified figure of eight (MFE) and compare it with other

Improving the quality of education is the goal of all pedagogical research. By using student surveys and course evaluations problem areas can be identified in most courses offered by universities. In this paper we perform a large-scale student survey in order to find the causes of, and remedies to, a widespread student dissonance in a mandatory course with over 100 students at Lund University. Our

Atrial natriuretic peptide (ANP) has a central role in regulating blood pressure in humans. Recently, microRNA 425 (miR-425) was found to regulate ANP production by binding to the mRNA of NPPA, the gene encoding ANP. mRNAs typically contain multiple predicted microRNA (miRNA)-binding sites, and binding of different miRNAs may independently or coordinately regulate the expression of any given mRNA.

Ever since the invention of the internal combustion engine, there has been an interest in optimizing the in-cylinder pressure to achieve reliable and efficient work output. With the use of in-cylinder pressure sensors, piezoelectric injector actuation, the possibility of multiple injection events and the increased availability of computation power, cycle-to-cycle, in-cylinder pressure optimization

Modelica allows systems to be described with reuseable components and with a high precision. To be able to use such complex models efficiently, high demands are set on tools that allow the user to extract the information needed from the models in a straight-forward manner. For this purpose, design-of-experiments techniques can be used to systematically analyze the complex models.In this paper, it

Lunds Universitets Historiska Museum har under det gångna året vidareutvecklat sin forskningsverksamhet och i samband med det tvåhundraårsjubileum som celebrerat museets långa historia och dess spännande framtid presenterat ett smakprov på Annette Frölichs sensationella fynd av kirurgiska instrument i Uppåkra. Det nystartade projektet, som heter »Läkekonstens Uppåkra», har nu kommit så långt att e

Background: Exposure to airborne particles has a major impact on global health. The probability of these particles to deposit in the respiratory tract during breathing is essential for their toxic effects. Observations have shown that there is a substantial variability in deposition between subjects, not only due to respiratory diseases, but also among individuals with healthy lungs. The factors d

Popular Abstract in Swedish Dieselmotorn, uppkallad efter sin uppfinnare Rudolf Diesel, patenterades 1892 och har sedan dess bidragit väsentligt till utvecklingen av samhället. Den viktigaste användningen är som kraftkälla i fordon och detta användningsområde ökar fortfarande. Andelen dieselmotorer i nyregistrerade personbilar i Västeuropa har nyligen passerat 50 %. För kommersiella fordon som lasThis project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. The results can be divided into two main categories: one about evaluations of optically accessible engines and one about studies of e

We studied the occurrence of arteriovenous (A-V) shunting in three experimental rat models, namely in rejecting allograft kidney, in uni- or bilateral ureteral obstruction, and in haemorrhagic hypotension. Isografted or sham-operated rats served as controls. Radiolabelled microspheres were injected into the renal artery and the increase in the amount of radioactivity in the lungs was considered to

Urgent structural change is required in higher education, to allow collaboration both within and across universities, so that achieving rapid sustainability transition can become not only the overarching but the main purpose of education, research and work in society. A review of the literature reveals that fragmentation caused by traditional hierarchical faculty and disciplinary organisation is a

An investigation into the implementation state of open standards in software is currently ongoing through the ISPRS/EuroSDR 'GeoBIM benchmark 2019' initiative, which kicked off earlier this year. The benchmark activity provides a way of assessing and comparing the functionality of different software packages in GIS and BIM in terms of their ability to handle standardised data (IFC and CityGML) and

In both the Geo and BIM domains, it is widely acknowledged that the integration of geo-data and BIM-data is beneficial and a crucial step in facing the multi-disciplinary challenges of our built environment. The result of this integration - broadly termed as GeoBIM - has a range of potential uses from district study to road safety. However, from the data perspective, this integration raises the qu

The aim of this paper is to present a proposal for a national building standard in Sweden. We define requirements for the proposed standard, e.g., it should support development of 3D city models, connect to building information models (BIM) and national registers and be based on a national classification system for the urban environment. Based on these requirements we develop an Application Domain

Partially Premixed Combustion (PPC) is an advanced combustion concept resulting in high efficiencies and low emission levels by the use of high levels of EGR and pilot injections. The main limitation of PPC to use in practice lies in the high pressure rise rate, which causes issues on engine noise and durability. In addition, soot emissions face with the overshoot problem during the transient oper
