Complex lake ecosystem models can assist lake managers in developing management plans counteracting the eutrophication symptoms that are expected to be a result of climate change. We applied the ecological model PCLake based on 22 years of data from shallow, eutrophic Lake Søbygaard, Denmark and simulated multiple combinations of increasing temperatures (0–6 ◦C), reduced external nutrient loads...

Thirty-one strains of Rhizobium leguminosarum were screened for their ability to fix nitrogen (effectiveness) on lentils (Lens esculenta). Fluorescent antibodies prepared against four of the most effective strains (NZP 5400, Hawaii 5-0, Nitragin 128A12, and Nitragin 128C53) and one other effective strain, Nitragin 175P1, were strain specific. NZP 5400, Hawaii 5-0, and Nitragin 128A12 were selec...

The abundance and relevance ofAccumulibacter phosphatis (presumed to be polyphosphate-accumulating organisms [PAOs]), Competibacter phosphatis (presumed to be glycogen-accumulating organisms [GAOs]), and tetrad-forming organisms (TFOs) to phosphorus removal performance at six full-scale enhanced biological phosphorus removal (EBPR) wastewater treatment plants were investigated. Coexistence of v...

Two studies were conducted utilizing 270 chickens to evaluate the efficacy of yeast culture (YC) for both broiler and layer ayian types. In the first experiment, three dietary levels (0, 1.25, 2.50 percent) of YC were included in a nutritionally complete ration and fed to 14-day-old broiler chicks for 8 days. Body weight gain, feed consumption (g) and feed efficiency were not influenced by yeas...

Small preterm infants often develop osteopenia with or without rickets and with or without fraewres. Whether these Ilone abnormalities all form part of the same disease process with a wide spectrum of presentation or whether each abnormality represents a different disease is as yet unclear. Bone mineralization depends largely on adequate supplies of calcium and phosphate. The normal intra-uteri...

The sheet resistance, effective carrier concentration, and Hall mobility of in situ boronand phosphorus-doped polycrystalline Si0.822yGe0.18Cy films are presented for carbon contents between 0% and 4%. Phosphorus and boron doping levels of 4310 and 2310 cm were achieved for the nand p-type layers, respectively, and remained largely unaffected by carbon content. The phosphorus-doped films showed...

We report high-resolution infrared absorption spectra of the neutral donors phosphorus and lithium, and the neutral acceptor boron, in isotopically pure 28Si crystals. Surprisingly, many of the transitions are much sharper than previously reported in natural Si. In particular, the 2p(0) line of phosphorus in 28Si has a full width at half maximum of only 4.2 microeV, about 5 times less than the ...
