Estimation of line properties in the copper access network

The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. This forces a deployment of the DSL transceivers in cabinets closer to the customers with a jo

Hepatocyte growth factor in cerebrospinal fluid differentiates community-acquired or nosocomial septic meningitis from other causes of pleocytosis.

Due to anatomical restrictions, the inflammatory response to intracerebral bacterial infections exposes swollen brain tissues to pressure and ischemia, resulting in life-threatening damage. Rapid diagnosis and immediate empirical antibiotic therapy is highly important. However, diagnosing meningitis in patients after neurosurgery is complicated, due to brain tissue damage and changes in cerebrospi

Early intervention in management of very preterm growth-restricted fetuses : 2-year outcome of infants delivered on fetal indication before 30 gestational weeks

OBJECTIVES: To describe the outcome of growth-restricted fetuses with absent or reversed end-diastolic flow (ARED) in the umbilical artery delivered on fetal indication before 30 gestational weeks.METHODS: Between 1998 and 2004, 42 fetuses with intrauterine growth restriction (IUGR) and ARED in the umbilical artery were delivered liveborn by Cesarean section on fetal indication before 30 gestation

Biological effects of a disposable, canisterless negative pressure wound therapy system.

Objective: Recent developments of negative pressure wound therapy (NPWT) systems have focused on making pumps smaller, lighter, and more portable. The recently introduced PICO system manages wound fluid through a highly breathable film within the dressing, thereby negating the need for a canister, which allows greater mobility and patient concordance. The aim of this study is to compare the biolog

On some Nonlinear Aspects of Wave Motion

In the first part of this thesis we consider the governing equations for capillary water waves given by the Euler equations with a free surface under the influence of surface tension over a flat bottom. We look for two-dimensional steady periodic waves. The problem is first transformed to a nonlinear elliptic equation in a rectangle. Using bifurcation and degree theory we then prove the existence

von Langenbeck procedures at 14 months or Wardill at 18 months for primary repair of cleft palate in adult Swedish patients with bilateral complete cleft lip and palate: A study of facial growth.

We compared facial growth in patients with bilateral complete cleft lip and palate (BCLP) in whom the palate had been repaired by the von Langenbeck procedure at the age of 14 months (L-14), or by the Wardill procedure at 18 months (W-18). A total of 151 unaffected subjects were used as a reference group. Thirty-six adult patients, 26 in the L-14 group, and 10 in the W-18 group, were investigated

Metoder för bestämning av njurfunktion. Vad har vi att erbjuda idag?

Bestämning av njurens förmåga att koncentrera urin är sedan länge ett väsentligt prov på njurfunktion vid tubulointerstitiell njursjukdom, t ex kronisk pyelonefrit. Desmopressintest är det främsta, men inte enda, testet för att bedöma njurarnas koncentrationsförmåga. Isotopundersökningar av njurarna utmärks av att de är enkla och skonsamma för patienten och utan kontraindikationer. Ofta kompletter

Cancer risk in patients hospitalized with polymyalgia rheumatica and giant cell arteritis: a follow-up study in Sweden.

Objectives. Studies reporting cancer risk after PMR and GCA are few, but it remains an issue of both concern and controversy. We examined the overall and specific cancer risks among Swedish subjects following hospitalization for these diseases. Methods. PMR and GCA patients were identified from the Swedish Hospital Discharge Register and by linking them with the Cancer Registry. Follow-up of patie

Against Truthmaker Necessitarianism

This paper is an argument against Truthmaker Necessitarianism — the doctrine that the existence of a truthmaker necessitates the truth of the proposition it makes true. Armstrong’s sufficiency argument for necessitarianism is examined and shown to be question begging. It is then argued in detail that truthmaking is a matter of grounding truth and that grounding is a dependency relation that neithe
