Tropical forest soils are a significant source for N2O and NO. Current estimates of N2O and NO emissions areuncertain due to the limited number of fieldmeasurements and model input data. Furthermore, considerable spatialand temporal variability exists due to variation of soil properties, vegetation characteristics and meteorology.Weused a process-based model (ForestDNDC-tropica) to estimate N2O an

The identification of carotid atheromatous plaques associated to a higher neurologic risk may be important in therapeutic decision making for asymptomatic patients and symptomatic patients with 50%-70% stenosis. The introduction of high-definition ultrasonography (HDU) and computer-assisted image analysis provides the possibility of a standard, objective and detailed characterization of the struct

A symposium held at Yarmouk University (YU), Jordan under the patronage of H.R.H. Prince Al-Hassan Bin Talal and in cooperation with Center for ME Studies at Lund University and Refugees, Displaced Persons, and Forced Migration Studies Center at YU. Speakers: Henry Diab - Leif Stenberg - Torsten Janson - Darcy Thompson - Khalid Al-Dabbas - Andrew Harber - Khalid Al-Wazani -

This paper examines the development of the role of a certain group of semi-officials, known as tongshi in Chinese, in Sino-Tibetan relations from the late-fourteenth century to the end of the eighteenth century, i.e. during the Ming and Qing dynasties, with particular reference to the part played by tongshi in events along the pre-modern Sino-Tibetan border. Tongshi were often Tibetans in Chinese

Compared to animals like ourselves, plants have a very flexible sexual life. Most plants are, for example, hermaphrodites with the potential capacity for reproduction by self-fertilization (or selfing). While selfing can provide several definite advantages for the individual plant, there is a downside; mainly the severe reduction in fitness due to inbreeding depression. To avoid the negative conse

Sustainability professionals are agents for change towards sustainable development. Such professionals require knowledge from a variety of disciplines, but also competencies to accomplish real-word change. This article evaluates an innovative course, Strategic Environmental Development, which immerses students in a real-life solution-oriented consultancy project in order to develop critical sustai

The ground and the excited state properties of the fullerene-linked quarter-thiophenes dyad were studied theoretically with the quantum chemistry method. To reveal the excited state properties of them in the vertical absorption process, the energies and densities of the HOMO and LUMO, the intramolecular charge transfer (ICT), locally excited (LE) are studied with transition density matrix, charge

The interaction between hydrogen peroxide and ozone has been studied in argon matrices using infrared spectroscopy. The spectra show that hydrogen peroxide forms a weak hydrogen bond to one of the end oxygens of ozone. A comparison is made with other ozone complexes.

The glacial unloading and resulting isostatic land uplift have together with hydro-isostasy, eustatic rise of sea-level and geoidal changes, ruled the shore displacement of Fennoscandia. Within the Baltic basin, periods of damming and shifts of outlet further complicated the shore displacement during the period studied, c. 12,200-8400 BP. Information on the Baltic history was derived from shorelin

We investigate correlations between geomagnetic activity indices, theNorth Atlantic Oscillation (NAO), and stratospheric geopotentialheights. It is shown that the correlation between the geomagnetic indexAp and the NAO index is high and significant since about 1970, that itis significant during winter only, that it was not significant beforeabout 1970, and that the correlations are dominated by qu

Objectives To obtain reference data representative of normal findings at anal endosonography in pregnant and non-pregnant women. To determine intraobserver and interobserver agreement in the detection of endosonographic anal sphincter defects in asymptomatic women. Methods Twenty-five non-pregnant nulliparous women and 25 non-pregnant parous women (age range, 20-67 years) and 47 pregnant women (a
