    A characteristic pattern of inflammatory pulmonary response was present in workers exposed to flock dust. The lesion is descriptively termed as lymphocytic bronchiolitis and peribroncholitis with lymphoid hyperplasia. The pulmonary response is suggestive of immunologic response to the flock dust. Furthermore, animal studies support the inflammatory ...

    Despite previous observations of adverse reproductive effects of toluene, including alterations of serum gonadotropins (luteinizing hormone, LH, and folliclestimulating honnone, FSH) in men, little is known regarding the mechanism of toxicity. We tested the hypothesis that toluene acutely suppresses pulsatile gonadotropin secretion by measuring LH ...

    At present, there is little knowledge concerning the shear strength of clays containing floating rock particles with concentrations from 0 to 30%. In practice, the effect of rock particles is typically disregarded in shear strength analysis. The two primary reasons for this are: 1) a lack of agreement concerning the influence of rock particles on m ...
