    Notes: Purpose - The paper addresses the effect friendly and friendship relationships among members of innovation teams on the performance of the teams. Design/methodology/approach - The members of innovation teams may develop friendly and friendship relationships over time. In our study, we focus on the effect of the frequency of such non-work relationships on team performance. For this research, we collected full network data on non-work relationships in a sample of 44 innovation teams and investigate how these "friendly and friendship networks" affect the performance of innovation teams. Findings - As result turns out that the frequency of friendly ties has positive as well as negative consequences on team performance, whereas the frequency of friendship ties positively relates to the performance. Research limitations/implications - The results indicate the importance of informal relations for the performance of innovation teams. Further, it is shown that friendly and friendship relations have different theoretical and practical implications. Future research can overcome the limitations of the presented research by concentrating on larger sample sizes and longitudinal research designs. Practical implications - Building on the results of the study managers can better orchestra innovation teams focussing not only on formal but also on informal contacts. The main practical implication is to strive for friendship contacts and to avoid too strong friendly contacts. Originality/value - The study adds knowledge to the research on informal relationships and performance two-fold. First, the findings testify that friendly and friendship contacts are different and not part of the same dimension, and there is strong evidence for the importance of informal contacts.

    Notes: Abstract Inelastic and elasticJ/ψ (3097) photoproduction on Li6 are measured at a mean γ energy of 90 GeV in an open spectrometer. TheJ/ψ are identified by their decays intoμ + μ − ore + e −. A signal of ψ′(3685) intoμ + μ − andJ/ψπ + π − is also seen. The inelastic cross-section withZ=E ψ/Eγ〈0.9 is compared in shape and magnitude with the colour singlet model of photon-gluon fusion.

    Topics: Biology , Medicine
    Notes: Summary We have produced a small library of colonic mucosa and colorectal carcinoma reactive monoclonal antibodies (MoAbs) by immunizations with extracts of human colon cancer tissue and a human colon cancer cell line. Hybridoma supernatants were tested on (normal and neoplastic) human tissues by immunoperoxidase methods to evaluate organ or tissue specificity. Initial biochemical characterization of the target antigens was performed by gelpermeation chromatography, Western blotting and competition assays. Based upon the immunoreactivity patterns and the characteristics of the antigen four groups of MoAbs could be distinguished. The first group concerns the antibodies PAR-LAM 3, 9 and 10. These antibodies react with an 87 kDa protein moiety in high molecular weight (2–5×106 Da) glycoproteins. In intestinal and colon mucosa these antibodies showed diffuse binding with goblet cells. In colon carcinoma decreased reactivity with these MoAbs was found. The second group consists of antibodies PARLAM 8, 12 and 13. These antibodies react with large (〉5×106 Da) glycoproteins, most likely with carbohydrate epitopes. By immunohistochemistry in normal colon mucosa the antibodies all show granular supranuclear reactivity with goblet cells. These antibodies show increased reactivity with colon adenomas and adenocarcinomas. A third group is formed by PARLAM 2, which also reacts with a large (〉5×106 Da) glycoprotein, showing a granular distribution in goblet cells. In colon carcinomas more extensive expression is found than in normal colonic mucosa. Finally, the fourth group consists of PARLAM 11, which also reacts with a large (〉5×106 Da) glycoprotein, located in the brush border of colonic columnar cells. These antibodies might be useful tools for the analysis of the expression of mucin related glycoproteins in normal, preneoplastic and neoplastic colon mucosa.

    Notes: Abstract Bana, or Low Amazon Caatinga is an evergreen sclerophyllous woodland. It occurs on bleached quartz sands in the lowlands of SW Venezuela, where it occupies relatively small ‘islands’ amidst Tall Amazon Caatinga which is exclusively developed on tropaquods. There is an outer vegetation belt about 20 m in width in which trees over 10 m in height occur (Tall Bana); its structure and floristic composition resemble Tall Amazon Caatinga. Low Bana (maximum tree height usually below 5 m) follows next. The central part is occupied by Open Bana in which even lower trees are very widely spaced. Destructive phytomass sampling was carried out for chemical analyses in seven plots along a 150 m line across the zonation. The total dry matter of living plants including roots of Tall Bana (30–32 kg/m2) compares rather well with 41 kg/m2 in Tall Amazon Caatinga. This is only 9–14 kg/m2 in Low Bana, and 4–6 kg/m2 in Open Bana. The average root % of total phytomass increases from 41% in Tall Bana to 63% in Low Bana, and is 88% in Open Bana. Average total dry dead above-ground phytomass (including standing trees and stumps) declines from 1 kg/m2 in Tall Bana to 0.2 kg/m2 in Open Bana. An accumulation of dead matter in Low and Open Bana, relative to the above-ground phytomass of living plants, is noted and this contrasts with the general absence of raw humus in the soil. Eighty-two species of woody plants (dbh≥1 cm) were recorded on the total plot area (640 m2); 90% of the species are also known to occur in Tall Amazon Caatinga. The species number declines from 59 in Tall Bana to 18 in Open Bana. Mesophylls sensu strictu dominate in Tall Bana, while notophylls are dominant in Low and Open Bana. Herbaceous species are less numerous: most of them belong to the Araceae, Bromeliaceae, Orchidaceae, Droseraceae, Eriocaulaceae and Xyridaceae.

    Interaction of hydrological systems and eutrophication of the Loosdrecht Lakes (1986)
    Springer
    Aquatic ecology 20 (1986), S. 17-25

    ISSN: 1573-5125
    Keywords: Loosdrecht Lakes ; hydrology ; water transport ; eutrophication
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The history of eutrophication of the Loosdrecht Lakes system and the differences in trophic state of the compartments of this system are described from a hydrological point of view. Groundwater movement was found to be of paramount importance. This groundwater transport induced a horizontal surface water transport with concomitant biomass from Loosdrecht Lakes to Lake Breukeleveen, which explains partly the more eutrophic situation in the latter lake. The article summarizes several internal WOL-reports (ENGELEN and KAL, 1985; HETTLING, 1985a, b; KUHNEL, 1985; TEUNISSEN, 1985).

    ISSN: 1434-601X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Excitation-energy sharing has been studied in the20Ne+54Fe reaction at 11 and 15 MeV/nucleon using projectile-like fragment-α correlations. Since the dominant part of the correlation can be described by sequential decay, primary excitation distributions were obtained. An unexpected strong asymmetry in the excitation-energy sharing is observed.

    Description / Table of Contents: Crystal Structure, F.I.R., and Raman Spectra of GaCrSe3The crystal structure of GaCrSe3 oP20 was determined by single crystal X-ray methods (final R = 1.6% for 949 observed reflections, I 〉 2σI). GaCrSe3 crystallizes in the orthorhombic space group Pnma with Z = 4 (CuTaS3 type) and a = 1011.82(7), b = 373.45(3), and c = 1239.2(1) pm. The structure is built up on rectangular columns in [010] of edge shared GaSe4 tetrahedra and CrSe6 octahedra of the sequence (GaSe4)(CrSe6)2(GaSe4) in [101] and [101], respectively, which are connected via the corners in such a manner that channels in [010] of trigonal prismatic cavities are formed. The single crystals were grown by vapour phase transport method using I2 as transporting agent. The f.i.r. and Raman spectra of GaCrSe3 as well as a group theoretical treatment of the phonon modes are reported. In the ternary system Ga2Se3-Cr2Se3, monoclinic Ga1,3Cr0,7Se3 and hexagonal CrGa1,66Se4 (FeGaS4-type) have been established additionally to the orthorhombic GaCrSe3.
    Notes: Die Kristallstruktur der bisher nicht beschriebenen Verbindung GaCrSe3oP20 wurde anhand von Einkristalldaten bestimmt (R = 1,6% für 949 beobachtete (I 〉 2σI) Reflexe). GaCrSe3 kristallisiert in der orthorhombischen Raumgruppe Pnma mit Z = 4 (CuTaS3-Typ) sowie a = 1011,82(7), b = 373,45(3) und c = 1239,2(1) pm. Der Struktur liegen rechteckige Säulen in [010] aus kantenverknüpften CrSe6-Oktaedern und GaSe4-Tetraedern der Folge (GaSe4)(CrSe6)2(GaSe4) in [101] bzw. [101] zugrunde, die über die Ecken der Oktaeder- und Tetraederbaueinheiten so verknüpft sind, daß in [010] angeordnete Kanäle mit trigonal-prismatischen Lücken gebildet werden. Die Darstellung von Einkristallen des GaCrSe3 erfolgte durch Gasphasen-transport mit Iod. Das FIR- und Ramanspektrum des GaCrSe3 sowie die Schwingungsabzählung der Gitterschwingungen dieses Strukturtyps werden mitgeteilt. Neben dem orthorhombischen GaCrSe3 existieren im System Ga2Se3-Cr2Se3 monoklines Ga1,3Cr0,7Se3 und hexagonales CrGa1,66Se4 (FeGa2S4-Typ).
