Intracytoplasmic inclusions containing Chlamydia psittaci were isolated by a newly established method. Infected L-cells at 20 h after infection were suspended in 0.25 M sucrose-tris(hydroxymethyl)aminomethane buffer containing ethylene-diaminetetraacetic acid, homogenized in a Dounce tissue grinder, and filtered through a 2,000-mesh screen. Isolated inclusions were stabilized in 5% bovine serum...

In this paper we study three aspects of (P(M)/ ∼), the set of Murray-von Neumann equivalence classes of projections in a von Neumann algebra M. First we determine the topological structure that (P(M)/ ∼) inherits from the operator topologies on M. Then we show that there is a version of the center-valued trace which extends the dimension function, even whenM is not σ-finite. Finally we prove th...

abstractintroduction: previous investigations have shown that protein malnutrition can alters the structure and function of some areas of hippocampal formation. we investigated the effect of protein malnutrition on amygdaloid projections to the ca1 hippocampal area. in this study we investigated level and pattern of distribution of efferent projections from amygdala to hippocampus in the rat by...

The method of periodic projections consists in iterating projections onto m closed convex subsets of a Hilbert space according to a periodic sweeping strategy. In the presence ofm ≥ 3 sets, a long-standing question going back to the 1960s is whether the limit cycles obtained by such a process can be characterized as the minimizers of a certain functional. In this paper we answer this question i...

Abstract Extreme storms cause extensive beach-dune erosion and are typically considered to enhance coastal due sea-level rise. However, extreme can also have a positive contribution the nearshore sediment budget by exchanging between lower upper shoreface and/or adjacent headlands, potentially mitigating some adverse rise impacts. Here we use three high-resolution morphological datasets of stor...

conclusion despite multiple exposures, ed control is more effective if wss is performed using apmdr in the aec mode. results using apmdr, the mean number of exposures was 6.1 for ap and 6.5 for lat projections. lat projections required more exposures (6.55%) than ap projections. the mean ed was 0.6276 msv (ap) and 0.6716 msv (lat). the mean ed for lat projections was 0.6061 msv in automatic exp...

Abstract. Digital tomography deals with the problem of reconstructing an image from its projections. The image may or may not be reconstructible uniquely. The effective reconstruction also depends on the kind of projections taken. We consider the simplest two-dimensional case in which we have a 2D matrix and the projections are orthogonal. The matrices which are not uniquely reconstructible are...

This work intends to define the resolution requirements for near-field projections in a psycho-physical study design evaluate participants’ perception under influence of different ambient lighting levels and various viewing distances. The variation distances relates daytime critical urban environments. application increases popularity communication- or safety-relevant projections, such as autom...

For a finite positive Borel measure μ on the unit circle, let D(μ) be associated harmonically weighted Dirichlet space. A shift invariant subspace M recognizes strong approximate spectral cosynthesis if there exists sequence of subspaces M_k, with codimension, such that orthogonal projections onto M_k converge in operator topology to projection M. If is sum atoms, then we show admits cosynthesis.
