The coefficient of vertical permeability, P z'averaged 365 gpd per square foot. Computed drawdown for the pumped well, based on this value, differed by only a small amount from the observed drawdown. The coefficient of storage, determined from type curves for an image well system, averaged 0.20, typical of unconfined aquifers. Application of the method required a thorough knowledge of geohydrologic controls operating at the test site.Type of Medium: Electronic ResourceURL: -

ISSN: 1745-6584Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Energy, Environment Protection, Nuclear Power EngineeringGeosciencesNotes: Watercourse aquifer systems in many areas are adversely affected by wastes disposed into surface-water sources, resulting in either reduced streambed permeability, infiltration of wastes into the aquifer, or both. These conditions are illustrated at Lancaster, Ohio, where low streambed permeability in the vicinity of the municipal well field, resulting from the discharge of wastes to the Hocking River, seriously retards the infiltration of surface water and lessens the available yield of the wells. The wastes consist of brine and iron-laden effluent from the municipal treatment plant, discharged within the area of influence of the pumped wells to a stream already carrying much organic waste and other debris. Upstream from the discharge sewer, muck and organic debris have accumulated thickly on the streambed, while downstream from the sewer the streambed sediments have become tightly cemented by iron and other constituents in the waste water. There is evidence that, despite reduced streambed permeability, wastes have entered the aquifer and have materially contributed to declines in well efficiency and to recurring problems of well maintenance.Conditions such as those illustrated at Lancaster occur also at Dayton and are not uncommon elsewhere in Ohio. Indirect contamination of aquifers and adverse physical and chemical alteration of streambed sediments, resulting from surface-water waste disposal, may in many places pose a threat to the ground-water supply. This fact should not be overlooked in determining water-quality standards to be established under the Water Quality Act of 1965.Type of Medium: Electronic ResourceURL: -

Published 1983Staff ViewISSN: 1365-3180Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: In glasshouse experiments, the addition of four ‘pyridine herbicides’ (substituted picolinic and pyridyloxyacetic acids) to either diclofop-methyl or flamprop-methyl had little effect on wild oat (Avena fatua) control. This contrasts with the serious antagonisms which occur with 2, 4-D and 2, 3, 6-TBA. With wild and cultivated oat, l'-methylheptyl (4-amino-3, 5-dichloro-6-fluoro-2-pyridyl)oxyacetate (Dowco 433) was completely compatible with diclofop-methyl and flamprop-methyl, and there was evidence that its presence improved the control of wild oats. Picloram, 3, 6-dichloropicolinic acid and triclopyr had only slight effects on phytotoxicity. The control of cleavers (Galium aparine) by picloram, triclopyr and Dowco 433 was not significantly reduced by addition of flamprop-methyl.Preliminary metabolism studies suggest that picloram does not greatly increase the rate of diclofop detoxification as do 2, 4-D and 2, 3, 6-TBA, and the observed compatibility could well be a direct consequence of this.The absence in these greenhouse experiments of serious antagonism between the pyridine herbicides and diclofop-methyl or flamprop-methyl suggests that ‘tank mixes’ of these herbicides could be used for the control of both broad-leaved weeds and wild oats.Type of Medium: Electronic ResourceURL: -

A series of tests has been devised to investigate the properties of these materials. They have been tested for strength, flexibility, lamination, fatigue life and radiolucency. Their properties have been compared with those of plaster of Paris in order that the role of the newer materials can be defined. It is suggested that the tests described might form the basis of a standard from which user trials could be designed to appraise the value of these materials in clinical practice.Type of Medium: Electronic ResourceURL: -

ISSN: 1420-908XSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract We have previously reported histamine desensitization of human blood mononuclear leukocytes resulting in reduced cAMP responses to β-adrenergic agonists, histamine and prostaglandin E1. This heterologous desensitization occurred at low, micromolar histamine concentrations and was accompanied by elevation of cAMP-phosphodiesterase (PDE) activity in these cells. We have now investigated the activity of PDE in the lymphocyte and monocyte fractions of mononuclear leukocytes to determine the site of histamine effect. PDE activity per cell was higher in monocytes (0.075±0.070 units) than lymphocytes (0.026±0.08) units). Monocytes responded to 10−6 M histamine stimulation with a much greater increase in PDE activity (0.354±0.1 units) than did lymphocytes (0.047±0.015 units). Histamine receptor studies, using thiazolylethylamine and chlorpheniramine as H1-agonist and antagonist respectively and dimaprit and cimetidine as H2-agonists and antagonists respectively, indicated that the histamine stimulation of PDE activity is mediated predominantly through H1 histamine receptor in the monocytes and the H2 receptor in the lymphocytes. Previously histamine had been thought to increase cyclic AMP by acting on H2 receptors to activate adenylate cyclase. Our studies show that stimulation of H1 or H2 receptors by low histamine concentration can cause the opposite effect i.e. increased catabolism and a net reduction in cAMP levels. The localization of this effect predominantly to monocytes indicates a potentially important mechanism for histamine action on immune regulation.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1084Keywords: Key words: Magnetic resonance imaging ; cerebral ; Globus pallidus ; Chronic liver diseaseSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract. Cirrhotic patients are known to have abnormally high signal principally in the globus pallidus on non-contrast T1-weighted MRI. The purpose of this study was to relate MR changes to clinical and pathological features of chronic liver disease. We confirmed abnormally high signal in the globus pallidus on T1-weighted images in 25 of 28 patients with chronic liver disease, showing that it also occurs in patients who have not yet progressed to cirrhosis. Changes were seen in patients both with and without clinical portosystemic shunting. This abnormality is not responsible for hepatic encephalopathy. Cholestatic disease was more likely to produce marked changes than non-cholestatic disease. No statistically significant correlation was demonstrated between the severity of liver disease and the degree of MR abnormality. However, marked improvement in MR appearances was seen after successful liver transplantation.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0762Keywords: Key words House sparrows ; Immunity ; Testosterone ; Corticosterone ; Status signalling ; Immunocompetence handicap hypothesisSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Many bird species have patches of colour in their plumage, contrasting with their basic coloration, which are used to display and signal status to conspecifics. These are called ’badges of status’, because they are believed to be low-cost signals of social status. For a signalling system to be evolutionarily stable, cheating must be controlled. The conventional view is that there is frequent testing, which uncovers cheats. Recently, the immunocompetence handicap hypothesis (ICHH) suggested that signals may be dependent on testosterone for their development, with a cost being imposed through immune suppression. We report experiments on house sparrows (Passer domesticus) which show that testosterone significantly influences the size of the bib (a ’badge of status’). The ultimate effect of the testosterone manipulation was to impair antibody production, as predicted by the ICHH. However, testosterone manipulations also changed the levels of the ’stress hormone’ corticosterone. The level of corticosterone was also related to the degree of immunosuppression. After controlling for the effect of corticosterone, testosterone enhanced the birds’ ability to produce antibodies, counter to the ICHH. The hypothesis therefore must be modified. We suggest that testosterone has a dual effect: it leads to immunosuppression through a mechanism involving corticosterone but, conversely, leads to increased immunocompetence probably via dominance influencing access to resources.Type of Medium: Electronic ResourceURL: -

ISSN: 1439-6327Keywords: Salbutamol ; Ergogenic aid ; Oxygen uptake kinetics ; CyclingSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract The effect of salbutamol (S) on cycling performance was examined in 15 highly trained non-asthmatic male cyclists. A double-blind, randomized cross-over design was used with S or placebo (P) administered using a metered-dose inhaler and a spacer device 20 min before each testing session. The S dose was 400 μg (four puffs), which is twice the normal therapeutic level. Subjects were habituated to all the laboratory procedures in the week prior to actual data collection. The subjects performed four tests under S and P conditions on separate days over 2 weeks. These included measurement of maximal O2 uptake $$(\dot VO_{2max} )$$ (cycle ergometry) with assessment of pulmonary function before and after, a submaximal (90% of ventilatory threshold) square-wave work transition from a base of unloaded cycling, a 60-s modified Wingate test, and a simulated 20 km time trial. No significant differences were observed in any of the dependent variables related to aerobic endurance or cycling performance between the S and P conditions. These results support other findings that an acute dose (400 μg) of S has no performance-enhancing properties.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-3017Keywords: lead shot ; lead sinkers ; lead poisoning ; birds ; toxicity ; environmental fateSource: Springer Online Journal Archives 1860-2000Topics: Energy, Environment Protection, Nuclear Power EngineeringNotes: Lead shot ingestion is the primary source of elevated lead exposure and poisoning in waterfowl and most other bird species. For some species (e.g. Common Loons, Gavia immer), lead sinker ingestion is a more frequent cause of lead poisoning. In freshwater environments where recreational angling activity and loon populations co-occur, lead poisoning from ingestion of small (〈50 gram) lead sinkers or jigs accounts for 10–50% of recorded adult loon mortality, depending on the locations studied. Lead shot ingestion occurs in waterfowl, and in a wide variety of non-waterfowl species, including upland game birds, shorebirds, raptors, and scavengers. Where it has been explicitly studied in Canada and the US, lead poisoning mortality of bald (Haliacetus leucocephalus) and golden eagles (Aquila chrysactos) from eating prey animals with lead shot embedded in their tissues accounts for an estimated 10–15% of the recorded post-fledging mortality in these raptorial species. In addition to environments that experience hunting with lead shot, clay target shooting ranges, especially those in which the shotfall zones include ponds, marshes, lakes, rivers, beaches, or other aquatic-type environments, create a significant risk of shot ingestion and poisoning for waterbirds. Metallic lead pellets deposited onto soils and aquatic sediments are not chemically or environmentally inert, although tens or hundreds of years may be required for total breakdown and dissolution of pellets. Functional, affordable non-toxic alternatives to lead shot and sinkers are being currently produced, and additional such products are being developed. Several countries have successfully banned the use of small lead sinkers, and of lead shot for waterfowl and other hunting, also for clay target shooting, using a phasing-out process that gives manufactures, sellers, and users adequate time to adjust to the regulations.Type of Medium: Electronic ResourceURL:
