This paper investigates the complex dynamical behavior of a rigid block structure under harmonic ground excitation, thereby mimicking, for instance, oscillation system seismic excitation or containers placed on ship periodic acting sea waves. The equations motion are derived, assuming large frictional coefficient at interface between and ground, in such way that sliding cannot occur. In additio...

At the Sint Augustinus Hospital, Antwerp, Belgium, all children with cholesteatoma are operated by a canal wall up approach and immediate reconstruction with a rympano-osslcular allograft. In the majority of the cases, a second stage is performed after I year. This paper presents the results ofa retrospective review ofthe charts of 103 consecutive children treated between 7979 and 1995. The mea...

Diffuse unilateral subacute neuroretinitis (DUSN) secondary to raccoon roundworm (Baylisascaris procyonis) infection has been reported in rural and suburban areas of North America and Europe with extant raccoon populations. Here, we present a case of Baylisascaris-induced DUSN from the densely populated borough of Brooklyn in New York City and alert urban ophthalmologists to consider this etiol...

In 1928, Baló described a law student with an unusual fatal illness marked by aphasia and a right hemiplegia, with later optic neuritis and normal cerebrospinal fluid. At autopsy, he found a disease of the white matter characterised by foci varying in size from a lentil to that of a pigeon's egg and presenting gray softening and, in part, concentricity, where the medullary sheaths were destroye...

BACKGROUND AND OBJECTIVES In the present study, isolation of Streptomyces associated with marine sponges and its bioactive potential against fish and shellfish pathogens were assessed. The Streptomyces sp. were isolated from the marine sponges namely Callyspongia diffusa, Mycale mytilorum, Tedania anhelans and Dysidea fragilis collected from Vizhinjam port, situated in the South-West coast of I...

Obsessions and compulsions are mental experiences with a compelling quality which persistently intrude into consciousness. Although recognized by the patient as an abnormal and irrational product of his own mind, and resisted by him, he is incapable of expelling them. They may take the form of thoughts, images, fears, urges, desires, or acts. An obsessional illness is one where such symptoms do...

Subacute and chronic affections of the myocardium due to non-penetrating injuries have in the past been regarded as extremely rare. Traumatic rupture of the cardiac valves, papillary muscles, and chordc tendine are described in detail in most textbooks; yet isolated myocardial and pericardial lesions, though undoubtedly more common, are scarcely mentioned except in more recent manuals dealing w...

Raised plasma immunoreactive corticotrophin (ACTH) levels were found in five boys with the sex-linked disorder progressive leucodystrophy associated with adrenal insufficiency (Addison-Schilder's disease) and in a symptom-free brother of one of them. Similar ACTH concentrations were found using two antisera, one against the N-terminal part of the ACTH molecule and the other against the C-termin...

Municipalities may have various motives for decisions on the mode of their task execution. Empirical studies – based on both public choice and transaction costs theory have not yet provided a fully comprehensive explanation for municipal contracting out decisions. Therefore, we held interviews with Dutch municipal managers about the motives for the actual mode of service provision. This study p...

There are two conceivable readings for (1). Either (a) it refers to the party or (b) Peter only disliked the food. Discourse grammars like Segmented Discourse Representation Theory (SDRT) offer an explanation for this phenomenon. SDRT an extension ofDRT (Kamp and Reyle, 1993) describes a complex propositional structure of Discourse Representation Structures (DRSs) connected via discourse relati...
