A frequency synthesizer applied to a 10/100Base-T ethernet transceiver is described. It can work adaptively in either a 10Mbps or 100Mbps mode and convert freely from on mode to another. Cascode current sources and differential delay cells are adopted to guarantee good performance. The circuit meets the requirements of both transmitter on rising/falling time and receiver on CDR so that additional

Hemiparasitic plants accumulate nutrients in their leaves and therefore produce high-quality litter with faster decomposition and nutrient release rates compared to non-parasitic litter. Higher levels of plant-available nitrogen (N) in the presence of hemiparasitic plants have been attributed to this 'litter effect', but effects on N dynamics in the soil remain unstudied. We tested the hypothesis

Popular Abstract in English Consumption of multimedia content is one of the main tasks we perform in our day-to- day lives, such as listening to music on an iPod or watching the news from an online steaming service. As technology has evolved and enabled easier access to different content (basically access anything anywhere), our consumption has grown. In only the last decades we have evolved from Multimedia has become one of the cornerstones of our 21st century society and, when combined with mobility, has enabled a tremendous evolution of our society. However, joining these two concepts introduces many technical challenges. These range from having sufficient performance for handling multimedia content to having the battery stamina for acceptable mobile usage. When taking a projection of w

A compilation of the applied experimental conditions when studying metal ion adsorption onto kraft fibres, and the resulting conclusion, revealed that the ionic strength conditions used during the experiments were an important dividing factor. At low ionic strengths, the conclusion has regularly been that the Donnan ion-exchange model could correctly predict the adsorption while, at higher ionic s

This article is a review of a book by the Swedish ethnologist Billy Ehn. The book gives a description and analysis of the events when four departments were integrated into one. The writing of the book resulted in a conflict that forced Ehn to resign as the dean of the newly created department. One reason for his resignation was that the staff of the department felt that they had not been properly

Adequate intravenous contrast media (CM) enhancement is crucial for evaluation of the coronary arteries.

Hairy cell leukemia is often reported as a disease of young males. The male predominance is strong, 4:1, but the median age in the Swedish national compulsory cancer registry is similar to that of follicular lymphoma, i.e. 62 years. The overall 6-year survival in the Swedish registry of patients diagnosed since 2000 is 80%, 93% of patients 60 years. The yearly risk of secondary cancers is 1.75%. C

Ventilation/perfusion single-photon emission computed tomography (V/Q SPECT) is the scintigraphic technique of choice for the diagnosis of pulmonary embolism and many other disorders that affect lung function. Data from recent ventilation studies show that the theoretic advantages of Technegas over radiolabeled liquid aerosols are not restricted to the presence of obstructive lung disease. Radiola
