Single deletions of the amino acids valine, tryptophan, threonine, histidine and isoleucine had no significant effect on weight gain but the deletion of lysine alone significantly reduced weight gain and caused fin erosion and mortality. Deletion of arginine reduced weight gain (P&lt;.05), but did not cause mortality or fin erosion. Feeding graded levels of each of these two amino acids showed that the minimum lysine requirement for maximum growth was about 6.1% of protein, and the minimum arginine requirement was between 5.4 and 5.9% of protein.

Several of these possibilities are discussed in terms of the rock cycle. The mineralogy of clays neoformed in the weathering environment is a function of solution chemistry, with the most dilute solutions favoring formation of the least soluble clays. After erosion and transportation, these clays may be deposited on the ocean floor in a lateral sequence that depends on floccule size. Clays undergo little reaction in the ocean, except for ion exchange and the neoformation of smectite; therefore, most clays found on the ocean floor are inherited from adjacent continents.

From the resulting dispersion relations we find that the spurious modes in elevation are associated with zero frequency and large wave number (wavelengths of the order of the nodal spacing) and consequently are zero-velocity modes. The spurious modal behavior is the result of the finite spatial discretization. By means of an artificial compressibility and limiting argument we are able to resolve the similar problem for the Navier-Stokes equations. The relationship of this simpler analysis to alternative consistency arguments is explained. This modal approach provides an explanation of the phenomenon in question and permits us to deduce the cause of the very complex behavior of spurious modes observed in numerical experiments with the shallow water equations and Navier-Stokes equations.

Using a simulation model which couples the hydrology of a conjunctive stream aquifer system to a behavioral-economic model which incorporates farmer behavior in such a system, we have investigated the economics of an area patterned after a reach of the South Platte Valley in Colorado. The results suggest that under current economic conditions the most reasonable groundwater pumping capacity is a total capacity capable of irrigating the available acreage with groundwater. Installing sufficient well capacity to irrigate all available acreage has two benefits: (1) this capacity maximizes the expected net benefits and (2) this capacity also minimizes the variation in annual income: it reduces the variance to essentially zero. As pumping capacity is installed in a conjunctive use system, the value of flow forecasts is diminished.

Rare-earth abundances for both basalts and andesites are particularly enriched in light rare-earth elements. High-Al basalts are more enriched than the \"low-Al\" basalt and have values comparable to the andesites. Labradorite and labradorite-pyroxene andesites all have negative Eu anomalies and hornblende andesites all have negative Ce anomalies. The former is probably due to changing plagioclase composition during fractionation and the latter to late-stage hydration of the magma. Least-squares mixing models indicate that neither high-Al nor \"low-Al\" basalts are likely sources for labradorite/labradorite-pyroxene andesites. High-Al basalts are considered to result from fractionation of olivine and clinopyroxene from a garnet-free peridotite at the top of the mantle wedge. Labradorite/labradorite-pyroxene andesites are mainly associated with an older NW-trending arc. The source is likely to be garnet-free but it is not certain whether the andesites result from partial melting of the top of the subducting plate or a hydrated lower portion of the mantle wedge. Pyroxene low-Si andesites probably result from cumulation of pyroxene and calcic plagioclase within labradorite-pyroxene andesites, and hornblende andesites by late-stage hydration of labradorite-pyroxene andesite magma. Olivine andesites, low-Si andesites and \"low-Al\" basalts are related to the NNE-trending Taupo-Hikurangi arc structure. Although the initial source material is different for these lavas they have probably undergone a similar history to the labradorite/labradorite-pyroxene andesites.

Temperatures ranged from 80–100°C at the outer edges of the cylinders to 250–300°C in central, drilled holes which housed the heating coils. The measured permeabilities of the granite cylinders decreased by as much as two orders of magnitude in experiments of 1–3 weeks' duration. The amount of permeability decrease varied directly with temperature and inversely with the rate of fluid flow. The compositions of the fluids discharged from the granites were functions of temperature and flow rate as well as mineral composition, with dissolved silica concentrations showing trends different from those of the other analyzed species. Fluids from experiments run at higher temperatures but at much lower initial rates of fluid flow had higher concentrations of most ions but substantially lower dissolved silica contents. In contrast, an increase in temperature at similar rates of fluid flow resulted in higher silica concentrations. In the experiments, the distilled water acquired enough dissolved materials at high temperatures to become supersaturated with respect to several minerals at the low-temperature edges of the cylinders. Some of this material, particularly silica, was deposited along grain boundaries and microfractures, causing the observed permeability decreases. The very low rates of fluid flow in some high-temperature experiments significantly increased the rates of SiO</span><sub>2</sub><span>&nbsp;precipitation and reduced dissolved silica concentrations relative to other species in the discharged fluids.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0016-7037(83)90267-3","issn":"00167037","usgsCitation":"Moore, D., Morrow, C., and Byerlee, J., 1983, Chemical reactions accompanying fluid flow through granite held in a temperature gradient: Geochimica et Cosmochimica Acta, v. 47, no. 3, p. 445-453, https://doi.org/10.1016/0016-7037(83)90267-3.","productDescription":"9 p.","startPage":"445","endPage":"453","numberOfPages":"9","costCenters":[],"links":[{"id":221354,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"47","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f593e4b0c8380cd4c2c8","contributors":{"authors":[{"text":"Moore, Diane E. 0000-0002-8641-1075","orcid":"https://orcid.org/0000-0002-8641-1075","contributorId":106496,"corporation":false,"usgs":true,"family":"Moore","given":"Diane E.","affiliations":[],"preferred":false,"id":360480,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Morrow, C.A.","contributorId":99977,"corporation":false,"usgs":true,"family":"Morrow","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":360479,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Byerlee, J.D.","contributorId":69982,"corporation":false,"usgs":true,"family":"Byerlee","given":"J.D.","affiliations":[],"preferred":false,"id":360478,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
