Cultures of Mycobacterium tuberculosis grown under oxygen depletion conditions enter into a state of nonreplicating persistence that may reflect a physiologically latent state. When these cultures were harvested and injected intranasally into mice, no bacteria could be recovered from the lungs for about 3 weeks, but after that evidence of regrowth was observed. Preimmunization of mice with a pa...

Distribution, abundance, habitat selection, and activity of bats in Wayne National Forest, Ohio, were studied during the winters and summers of 1979 and 1980. Methods included winter surveys of abandoned mines and mist netting of riparian sites in summer. Four species of bats were found hibernating in 23 of 65 coal mine shafts examined, and big brown bats, Epteskus fuscus, were most abundant. M...

Time history response analyses of horizontal hybrid wooden structures with RC core on one or both sides are conducted considering the elasto-plasticity part Wayne-Stewart model as hysteretic characteristics. Then, by comparing results static analyses, effects amplification and eccentricity verified, consistency load-carrying capacity calculation, such setting structural characteristics factor D...

A 68-year-old male patient has history of severe emphysema and esophageal achalasia. He was admitted to the intensive care unit with acute on top of chronic hypercanic respiratory failure and right lower lobe pneumonia. The patient improved after treatment for aspiration pneumonia with antibiotics and supportive measures. Figure 1 is an anteroposterior (AP) view of the chest showing bilateral b...

A point light source flickering on and off during a sac-cade projects a pattern onto the retina. The perceived pattern differs from the retinal pattern, with this difference reflecting the perisaccadic shift of spatiotopic coordinates. Hershberger (1987) characterized the perceptual pattern as a phantom array, fixed in space, with the sequential order of the flashes creating an impression of ap...

1.1 Statement (Matijevic–Roberts type theorem (MRTT)). Let C be a class of noetherian local rings. Let R be a noetherian Z-graded ring, and P its prime ideal. Let P ∗ be the prime ideal generated by the all homogeneous elements of P . If RP ∗ ∈ C, then RP ∈ C. Clearly, the truth of the statement depends on the choice of C. Nagata conjectured the Matijevic–Roberts type theorem for the case that ...

In the abstracts that follow the author who presented the paper is marked with an *. The last two abstracts were poster demonstrations and the remainder were clinical papers. The X-ray quiz was won by Mr. D. Halpin of Torbay and the SWOC Prize certificate was won by Miss D. Eastwood of Bristol. The Pridie Memorial lecture entitled "South West Orthopaedics 1948-91" was given by Mr. A. H. C. Ratliff
