System Dynamics (SD) is a method that allows for integrated modelling of technical as well as managerial aspects responsible for the dynamic complexity of systems. Therefore, simulation of SD models can also be a tool for problem analysis within software organisations. In this paper, experience with SD modelling of software processes and projects within Siemens is reported. Special focus is put on

This paper addresses the question whether a connection exists between subject omission and discourse anchorage in early Swedish child language. By analysing data from three Swedish children, I investigate whether previous mentioning in the discourse affects the occurrence of subject omission. A Danish study by Hamann & Plunkett (1998) reported that no connection between subject omissions and d

Solid tumors are less oxygenated than their tissue of origin. Low intra-tumor oxygen levels are associated with worse outcome, increased metastatic potential and immature phenotype in breast cancer. We have reported that tumor hypoxia correlates to low differentiation status in breast cancer. Less is known about effects of hypoxia on non-malignant cells. Here we address whether hypoxia influences

A new method to deal with nonorthogonalities in transition calculations has been implemented and tested. Large-scale transition calculations using the multiconfiguration Hartree-Fock (MCHF) method have been performed for the resonance line of B II at 1362 Angstrom. In these calculations the orbital sets of the initial and final-state wavefunctions have not been assumed to be equal but have been op

This thesis contains four independent studies that analyze various aspects of the nexus of inequality, globalization, and health with the aim to build our knowledge so some of the empirical relationships connecting these three concepts. Using data on four welfare attributes in Zambian households, Chapter 2 explores three approaches to evaluate multidimensional inequality. The examination indicate

In this paper an approach to extreme event control in wastewater treatment plant operation by use of automatic supervisory control is discussed. The framework presented is based on the fact that different operational conditions manifest themselves as clusters in a multivariate measurement space. These clusters are identified and linked to specific and corresponding events by use of principal compo

Kalkutfällning är en vanlig typ av missfärgning av fasader. Ibland kan det tyckas vara slumpmässigt vilka fasader som drabbas. Det finns emellertid vissa omständigheter som styr uppkomsten av kalkutfällning. Med kännedom om dessa kan riskerna för kalkutfällning minskas avsevärt. Detta kräver dock omsorg vid såväl materialval som utförande.

PURPOSE: The aim of this study was to examine the effects of persulphate on the nasal mucosa and on the immune cells in hairdressers suffering from bleaching powder associated rhinitis (BAR) versus subjects with rhinitis not previously exposed to bleaching powder. METHODS: Fifteen hairdressers (S) with BAR, 14 without symptoms (WS) and 12 atopics (A) with rhinitis but without exposure to bleaching

Omsorg kring barn studeras oftast utifrån föräldrars perspektiv och utifrån antaganden om kärnfamiljen som omsorgens nav. Vad händer om vi istället tar utgångspunkt i barns berättelser om omsorg? Vilka omsorgspraktiker och –relationer framträder då?

Neisseria meningitidis is a normal commensal of human mucous membranes that is no longer considered to be restricted to the nasopharynx. Due to the practice of oral sex, the mucous membranes of the cervix, urethra or anus have become a potential infection site for this bacterium. Inserting an intrauterine device (IUD), can alter the protective barrier of the endocervical mucosa, allowing for bacte

Artikeln beskriver ett nytt sätt att syntetisera tröghetsnavigeringssystem. Systemet är baserat på en princip för vertikalindikering, som uppfanns av författarna 1959. Ett komplett navigeringssystem enligt den nya principen har utvecklats och byggts av Philips Teleindustri i Stockholm. Detta system har genomgått en omfattande testning i flygplan. De första testflygningarna utfördes med ett litet t
