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

Let B be a Banach space and F any family of bounded linear functionals on B of norm at most one. For x ∈ B set || x || = supΛ∈F Λ (x) (||· || is at least a seminorm on B). We give probability estimates for the tail probability of S* n = max1≤ k≤ n ||Σk j=1 Xj || where {Xi}n i=1 are independent symmetric Banach space valued random elements. Our method is based on approximating the probability that

On Gotland medieval ruins and unfinished churches bear witness of a Golden Age, which suddenly was interrupted. With the enormous chancel ofKällunge as a point of departure I ask, why medieval Gotland declined. Hitherto the explanations have been a shift in the transit trade in the late 13th C., the civil war between Visby and the countryside in 1288, the Pla- gue of 1350, the invasion by the Dan
