In this paper, new physical limitations on the extinction cross section and broadband scattering are investigated. A measure of broadband scattering in terms of the integrated extinction is derived for a large class of scatterers based on the holomorphic properties of the forward scattering dyadic. Closed-form expressions of the integrated extinction are given for the homogeneous ellipsoids, and t

INTRODUCTION: Complications after lumbar anaesthesia and epidural blood patch have been described in patients with congenital small spinal canal and increased epidural fat or epidural lipomatosis. These conditions, whether occurring separately or in combination, require magnetic resonance imaging for diagnosis and grading, but their clinical significance is still unclear. CASE PRESENTATION: A 35-y

Scand J Caring Sci; 2010 Parents' experience of living with a baby with infantile colic - a phenomenological hermeneutic study Background: About 10% of newborn babies have infantile colic which means that they cry more than 3 hours per day. The baby's crying risks disturbing the early parent-child interaction. Objective: This study aimed to illuminate the meaning of being a parent of a baby with i

Pancreatic cancer is a devastating disease with poor prognosis. It is characterized by a pronounced stromal reaction, which resists chemotherapeutics and effective tumor treatment. Pancreatic stellate cells (PSCs) are mainly responsible for this stromal reaction. Moreover, the cancer and stromal interaction seems to promote tumor proliferation. In this study, L49H37, a newly synthesized curcumin a

This paper is a contribution to the never settled debate on reference, negation and presupposition of existence in the linguistic/philosophical literature. Based on Swedish and English data, the discussion is an attempt to present a unified account of the opposing views put forward in the works of Aristotle, Frege (1892), Russell (1905) and Strawson (1950). The starting point is the observed asymm

OBJECTIVE: We compared extended and limited lymph node dissections performed during radical cystectomy with regard to impact on survival and time to recurrence in bladder cancer patients. METHODS: We analyzed 170 patients who underwent radical cystectomy for urothelial carcinoma between January 1997 and December 2005. From 1997 to 2000, 69 of the patients were subjected to limited lymph dissection

Managementböckerna fortsätter att strömma ut på marknaden. I mångfalden är det givet att man finner en och annan bra och en och annan dålig bok. Ingvar & Sandberg lanserar inte mycket nytt, utan förmår endast knyta an till en idag ganska kraftlös sociobiologisk trend. Bennis & Nanus bryr sig inte så mycket om trender. De har en självständighet i sitt sökande efter ledarskapets "själ"... Ja
