T FIRST fertilizer plats on this continent devoted to lawn grasses were started by the Rhode Island Agricultural Experiment Station. Sulphate of ammonia and nitrate of soda, alone and in combination, were used as the source of nitrogen. Superphosphate and muriate of potash were added to make a complete fertilizer. The plats were laid down in 1907 and were fertilized continuously until 1942, whe...

Abstract The 2D Online Bin Packing is a fundamental problem in Computer Science and the determination of its asymptotic competitive ratio has attracted great research attention. In a long series of papers, the lower bound of this ratio has been improved from 1.808, 1.856 to 1.907 and its upper bound reduced from 3.25, 3.0625, 2.8596, 2.7834 to 2.66013. In this paper, we rewrite the upper bound ...

BACKGROUND Sarcoidosis is an idiopathic granulomatous disease with pathologic and immunologic features similar to tuberculosis. Routine histologic staining and culture fail to identify infectious agents. An alternative means for investigating a role of infectious agents in human pathogenesis involves molecular analysis of pathologic tissues for microbial nucleic acids, as well as recognition of...

Endospores of Bacillus subtilis are enclosed in a proteinaceous coat which can be differentiated into a thick, striated outer layer and a thinner, lamellar inner layer. We found that the N-terminal sequence of a 25-kDa protein present in a preparation of spore coat proteins matched that of the Mn-dependent superoxide dismutase (SOD) encoded by the sod4 locus. sod4 is transcribed throughout the ...

wood resources, non-wood plants and recycled papers are the common raw materials of papermaking. shortage of raw materials, is a challenging problem in developing pulp and paper industry. in this study, cladophora green algae was used as a new source of cellulosic fiberfor pulping and papermaking.. cladophora algae was cooked with cold soda method and then was mixed with nssc pulp at 10,20 and ...

This paper describes the SODA scheduler for System S , a highly scalable distributed stream processing system. Unlike traditional batch applications, streaming applications are open-ended. The system cannot typically delay the processing of the data. The scheduler must be able to shift resource allocation dynamically in response to changes to resource availability, job arrivals and departures, ...

Results: The real price (inflated to 2006 US dollars) of soda and pizza decreased over time; the price of whole milk increased. A 10% increase in the price of soda or pizza was associated with a −7.12% (95% confidence interval [CI], −63.50 to −10.71) or −11.5% (95% CI, −17.50 to −5.50) change in energy from these foods, respectively. A $1.00 increase in soda price was also associated with lower...

Reduced reproductive success has contributed to lack of recovery of the endangered western North Atlantic right whale (Eubalaena glacialis). Here we examined the specific life history period from just before birth through the first year to estimate calf and perinatal losses between 1989 and 2003. The lower bound estimate (17 mortalities from 208 calving events) included documented calf mortalit...

Rainfall simulation experiments were conducted on annual grassland and coastal sage scrub hillslopes to determine the quantities of C and N removed by surface runoff in sediment and solution. Undisturbed coastal sage scrub soils have very high infiltration capacities (> 140 mm h(-1)), preventing the generation of surface runoff. Trampling disturbance to the sage scrub plots dramatically reduced...

The black liquor (BL) obtained by straw pulping can hardly be applied to conventional alkali recovery systems because of its high concentration silicon and viscosity. Soda-oxygen synchronously deposit silica on the surface cellulose reduce content viscosity BL remarkably. In this paper, BLs wheat soda-oxygen at different end points (pH < 10, 11.5 pH 12) soda-anthraquinone (soda-AQ) were obtaine...
