nitrogen use efficiency and life cycle of root nodules in alfalfa after different mineral fertilization and soil cultivation practices were studied. field trial was conducted in the institute of forage crops, pleven, bulgaria on leached chernozem subsoil type and no irrigation. the next treatments were tested: i) for fertilization as follows: n0p0k0 (control); n60p100k80 (an accepted technology...

Diverticula are thought to arise from defects in the muscularis layer of the intestines (Fig. 35.1) and are related to abnormalities in muscle tone and increased intraluminal pressure; saclike protrusions eventually form at points of weakness. If stool is caught in these sacs, it becomes inspissated and hardened and causes abrasions of the mucosa that lead to inflammation, although the same end...

Radio continuum and polarization observations of the entire Cygnus Loop at λ6 cm wavelength were made with the Urumqi 25 m telescope. The λ6 cm map is analysed together with recently published maps from the Effelsberg 100 m telescope at λ21 cm and λ11 cm. The integrated flux density of the Cygnus Loop at λ6 cm is 90±9 Jy, which implies a spectral index of α = −0.40 ± 0.06 being consistent with ...

CM: Problem Management is a detailed problem management process model to be utilised within corrective maintenance. It has been developed at ABB and evaluated for its industrial relevance within 17 non-ABB organisations. In this paper, we present the evaluation results of CM: Problem Management. Our primary goal is to confirm its industrial relevance. Our secondary goal is to establish current ...
