    NATIONAL INCOME, WELFARE, AND THE ENVIRONMENT (1978)

    Notes: This article explores the assumptions underlying present definitions of national income in its principal uses, and considers the alterations that would be needed to allow for the inclusion of environmental quality. A numerical example illustrates the impact of alternative measures. The discussion concludes that if we want national income to conform more closely to theoretical concepts of welfare indices, then we need to include a proxy for those environmental services that would not be completely free goods if it were possible to overcome their inherent non-marketability. The least unsatisfactory proxy would be the spending on environmental protection.

    Notes: Summary Background Although skin is typically the first site of involvement of acute graft-versus-host disease (GVHD), most standard recommended staging and grading criteria allow enrolment of patients with involvement of GVHD target organs other than the skin in studies analysing risk factors for acute GVHD after stem cell transplantation (SCT). Objectives To determine the risk factors for developing histologically confirmed acute cutaneous GVHD in patients who underwent allogeneic SCT for different haematological disorders. Methods This retrospective study was based on review of clinical files and databases from 300 consecutive patients with several haematological disorders who received allogeneic SCT between 1 January 1984 and 31 December 1999 at Hospital Universitario de la Princesa, Madrid, Spain. Variables evaluated included diagnosis of haematological disorder, age and gender (donor and recipient), HLA matching, female donor to male recipient, donor and recipient viral serology (cytomegalovirus), conditioning regimen, GVHD prophylaxis, blood counts at day of engraftment, mortality, cause of death, and survival at 100 days, 5 years and 10 years following SCT. Results In multivariate analysis, risk factors for acute cutaneous GVHD were type of haematological disease (P = 0·006), HLA disparity (P = 0·006), number of transplants per patient (P = 0·017), conditioning regimen (P = 0·001), and GVHD prophylaxis (P = 0·025). Survival rates did not differ significantly for cases and controls. Conclusions Risk factors for acute cutaneous GVHD were a diagnosis of chronic myeloid leukaemia, HLA disparity, receipt of more than one SCT, conditioning regimens including total body irradiation, and GVHD prophylaxis regimens other than ciclosporin plus methotrexate. Other common risk factors for acute GVHD without specific target organ involvement showed no significant association with the risk for developing acute GVHD affecting the skin as primary target organ.

    Notes: Six of 19 psychrotrophic bacteria common in milk and meat hydrolyzed large amounts of p-nitrophenyl-glycosides during 48 hr in minimal growth broth at 20°C. Four of the 19 were inactive against the four glycosides used in the screening tests, and nine were weakly active. In tests of the six active cultures against 11 p-nitrophenyl-glycosides, strains of Enterobacter had more glycosidase activity than strains of Pseudomonas, β-anomers were hydrolyzed more rapidly than α-anomers, more p-nitrophenol was released from the β-D-galactoside than from other substrates, there was activity against the D form but not the L form of fucoside, and p-nitrophenyl-β-D-glucoside was hydrolyzed at about the same rate by each culture.

    Notes: Abstract Estimates of the extra earnings for jobs with higher risks of death are used in cost-benefit studies involving risk changes. Because of this use, the magnitude and stability of the estimated coefficient are important. Part of the current study closely reproduces the 1982 study by Marin and Psacharopoulos to check on the stability. We also examine the robustness of the estimate to the inclusion/exclusion of non-fatal risks and other relevant characteristics. While the magnitude of the coefficient has increased from the earlier study, the coefficient is robust to other changes in the specification. This yields a “value of life” figure of £9.7 million.

    Notes: Abstract: Proton-π0 coincidences have been measured at the beam energy of 180A MeV in the reaction Ar+Ca studied by TAPS at SIS/GSI. In the proton-π0 invariant mass spectrum we observe a significant excess of strength above the background obtained by event mixing. We attribute this signal to the strength distribution N Δ of the Δ baryonic resonance. No correlation is observed in the case of deuteron-π0 coincidences. Assuming isotropic emission of π0 and Δ+ from a midrapidity thermal source and isospin symmetry, we determined the global N Δ/N πratio of 0.79 ±0.30(stat) ±0.2(syst). This value indicates that most pions produced at subthreshold energy in heavy-ion reaction are mediated by the Δ-resonance.

    Inelastic interactions of protons with photoemulsion nuclei at 4·5 GeV/c (1981)

    Topics: Physics
    Notes: Abstract In inelastic collisions of protons with photoemulsion nuclei at 4·5 GeV/c, data have been obtained on multiplicity of shower particles, energy spectrum of fast secondary protons with (2·5±0·1) GeV average energy, and energy spectrum of produced charged pions with (640±±50) MeV average energy. The multiplicity, angular distributions, and energy of particles arising from splitting target-nuclei are also determined: the proton spectrum is approximated by the power dependenceE -γ withγ=1·4±0·1. The distribution of protons andπ-mesons over rapiditiesy=0·5 In[(E+p)/(E−p)] have been obtained. The average multiplicity for secondary particles coincide with the predicted values given by the cascade-evaporation model.

    Comparative role of phosphate in soil or inside the host on the formation and effects of endomycorrhiza (1978)

    Notes: Summary Non-mycorrhizal plants grown 5 weeks in a low-phosphate soil with different amounts of soluble P were transplanted to soil also with different levels of phosphate and inoculated with VA mycorrhiza. The intensity of mycorrhizal infection as affected by the interaction of differents levels of phosphate in soil and in the host was examined after a further 8 weeks. In the soil with no added phosphate mycorrhizal infection was not affected by the initial P content of the plants. When 0.8 or 1.5 g K2PO4 was given per kg soil both the external and the internal P negatively influenced the infection. In some conditions a P content that was supraoptimal for infection was not for plant growth. The critical P concentration in plants depends on the age of the host. An interaction between P and N as a factor contributing to phosphate ‘toxicity’ is discussed.

    Notes: Abstract New experimental data on proton-nucleus interactions in emulsion at primary momentum 4.5 GeV/c are presented and discussed. The data are systematically compared with predictions of the cascade-evaporation model. The directions of development of the cascade-evaporation model in a region of incident momenta are considered, and some suggestions are made for giving it more precision.

    Description / Table of Contents: Verhalten von ferritischem Stahl Irn ML-1 NatriumkorrosionskreislaufDer ferritische Stahl AISI 430 wurde 6000 h bei 500 und 570 °C im ML-1 Natriumkreislauf ausgelagert. Die Proben wurden zur Auswertung der Korrosions- und Ablagerungseffekte nachuntersucht. Zusätzlich zu den Gewichtsänderungsmessungen und metallographischen Techniken wurden Oberflächenanalysen mit der Glimmentladungsspektrometrie und der AUGER-Elektronenspektrometrie sowie das Rasterelektronenmikroskop mit Röntgen-Analyse herangezogen.Korrosion und Ablagerung beeinflußten etwa 0,01 mm dünne Schichten, die Gewichtsverluste waren denen der austenitischen Stähle vergleichbar. Der Stahl wurde durch Natrium nicht entkohlt. Auf den Oberflächen hatten sich Sauerstoff enthaltende Verbindungen gebildet. In der Zone der Abströmung wurden auch metallische Ablagerungen, die an Nickel reich waren, beobachtet.
    Notes: The ferritic steel AISI 430 has been exposed up to 6000 hours at 500 and 570 °C in the ML-1 sodium loop. The specimens were examined to evaluate the corrosion and mass transfer phenomena. Additional to weight change measurements and metallographic techniques surface layer analyses by Glow Discharge Optical Spectrometry and AUGER Electron Spectrometry and also scanning electron microscopy with Xray analysis were applied.Corrosion and deposition influenced about 0.01 mm thin layers, weight losses were comparable to those of austenitic steels. The steel was not decarburized by the sodium. On the surfaces oxygen containing compounds have formed. In the down-stream area also metallic deposits rich in nickel were observed.
