Popular Abstract in Swedish I avhandlingen redovisas undersökningar av näringsdynamiken hos fem olika lövträdsarter (ask, björk, bok, ek och lind) vilka jämförs med gran, som är ett mycket undersökt trädslag ur närings-synvinkel. Målsättningen med studierna var att klargöra de olika trädslagens näringstillstånd under likartade förhållanden, deras inverkan på och samspel med marken, samt deras näriThis thesis considers several important aspects of nutrient dynamics and allocation in adult stands of Swedish forest tree species (Quercus robur L., Tilia cordata Mill., Fraxinus excelsior L., Betula pendula Roth., Fagus sylvatica L. and Picea abies (L.) Karst) planted on the same soils. Differences between species in macro- (N, P, K, Ca, Mg, S), and micro- (B, Cu, Fe, Mn, Zn) nutrient levels in

We extend our earlier work on the massive O(N) non-linear sigma model to other observables. We derive expressions at leading order in the large N expansion at all orders in the loop expansion for the decay constant, vacuum expectation value, meson meson scattering and the scalar and vector form factors. This is done using cactus diagram resummation using a generalized gap equation and other recurs

One option for coping with wasteful uses of fresh water in landscape irrigation is to use the treated greywater(GW). In the present study, an evaluation of a simple treatment system for reusing GW to irrigate green areas,trees, and ornamentals all over the campus in Tafila Technical University (TTU), Jordan, is presented. After 12 months of using the treatment system, the necessity for using fresh

This article gives an overview of some ethical problems raised in connection to nutritional genomics, especially the use of knowledge from nutrigenomics as a basis for personalised nutrition after a genetic test.

The high temperature CaO/SO2 reaction was studied using four Swedish limestones and one dolomite as sorbents. The measurements were carried out in a vacuum thermogravimetric analysis (TGA) apparatus in order to investigate the intrinsic reaction mechanism. The reaction was found to be fast at the beginning due to the surface reaction, while the subsequent stage was controlled by the product layer

The association between psychosocial work conditions, unemployment, and generalized trust was investigated. The health survey in Skane is a cross-sectional postal questionnaire study with a 59% participation rate. A total of 5,180 persons that belonged to the work force and the unemployed were included. Logistic regression models were used to investigate the associations between psychosocial facto
