A coincidence scintillation spectrometer
The coincidence spectrometer consists of two scintillation spectrometers, each of which can be used as either a beta-ray or a gamma-ray spectrometer, depending on what crystals are used. The pulses from the first spectrometer are analyzed with a single channel analyzer. The pulses corresponding to a certain energy are picked out with the analyzer and are fed into one channel of a coincidence ci...
متن کاملSarcoidosis and spondyloarthritis: A coincidence or common etiopathogenesis?
Background: Sarcoidosis is a multisystem granulomatous disease. Co-existence with spondyloarthritis (SA) has been more described as an adverse effect of anti-TNF α therapy than an association. We report herein a case of a typical sarcoidosis confirmed by histological proofs and an advanced SA with a bamboo column. Case Presentation: A 48-years-old woman presented with inflammatory back p...
متن کاملCardiac Rhabdomyomas and Congenital Hypothyroidism: A Coincidence or Hamartia
Cardiac rhabdomyomas are the most common primary cardiac tumors in children. These tumors are generally asymptomatic, although they may be associated with neonatal tuberous sclerosis complex. Despite the fact that thyroid dysfunction rarely occurs in tuberous sclerosis, papillary adenomas (hamartomas) of the thyroid gland have been reported in a number of autopsies. Herein, we present the case ...
متن کاملA Lefschetz-type Coincidence Theorem
A Lefschetz-type coincidence theorem for two maps f, g : X → Y from an arbitrary topological space to a manifold is given: Ifg = λfg, that is, the coincidence index is equal to the Lefschetz number. It follows that if λfg 6= 0 then there is an x ∈ X such that f(x) = g(x). In particular, the theorem contains well-known coincidence results for (i) X,Y manifolds, f boundary-preserving, and (ii) Y ...
متن کاملOral Verrucous Carcinoma and Ameloblastoma: A Rare Coincidence
Introduction: Oral verrucous carcinoma (OVC) is a rare malignancy of the oral cavity that was first described by Ackerman. This tumor is a well-differentiated low-grade, slow growing cancer that is locally invasive without metastasis. Ameloblastoma is one of the most common odontogenic tumors, which originates from the odontogenic epithelium. Verrucous carcinoma along with central ambloblastoma...
