BACKGROUND/AIM Although post-tonsillectomy hemorrhage is one of the most frequent and potentially life-threatening complications, there is no generally accepted classification of post-operative bleeding intensity. The aim of this study was to evaluate the intensity of post-tonsillectomy hemorrhage according to the five-grade classification. METHODS A total of 408 consecutive patients, aged 2 ...

UNLABELLED Although a large collection of classification software packages exist in R, a new generic framework for linking custom classification functions with classification performance measures is needed. A generic classification framework has been designed and implemented as an R package in an object oriented style. Its design places emphasis on parallel processing, reproducibility and exten...

We analyze the problem of fully implementing a social choice set in ex post equilibrium. We identify an ex post monotonicity condition that is necessary and—in economic environments—sufficient for full implementation in ex post equilibrium. We also identify an ex post monotonicity no veto condition that is sufficient. Ex post monotonicity is satisfied in all single crossing environments with st...

both at11th edition of the international classification of diseases (icd-11) and in fifth edition of the diagnostic and statistical manual of mental disorders (fifth edition-dsm-5), have pointed out that attitudes and quality of sleep can be seriously impaired by post-traumatic stress disorder (ptsd). the present study was conducted to compare hostility and sleep disorders among nursing student...

background: mental disorders may lead to several complications in adolescents’ people whose compensation is very difficult and sometime impossible. they are prone to emotional problems. therefore, knowing prevalence of diseases and valid statistical technique is necessary to plan for prevention and control of diseases. methods: in this cross-sectional study; direct, synthetic, and post-stratifi...

We study what kind of equilibria of which mechanisms are ex post renegotiation-proof (EPRP), i.e., robust against the possibility of ex post renegotiation under a variety of renegotiation procedures, and which social choice functions are EPRP implementable. In complete information environments with two agents only budget balanced Groves allocations are EPRP implementable, while with three or mo...

introduction: application of light transmitting posts to restore greatly damaged endodontically treated teeth has been increased. it is suspected that light intensity decreases as it passes throughout different materials. this can reduce the degree of conversion required for adequate bond strength throughout the length of these posts. the objective of this study was to evaluate the amount of li...

statement of problem: currently there are three recognized theories about the diameter of prepared dowel space in endodontically treated teeth. diameter of the dowel is commonly contributed to the root fracture. purpose: this study used a 3 dimensional (3d) finite element method to predict stress distribution in endodontically treated central maxillary tooth with cast post and core with various...

It is shown that under the post-Newtonian approximation the Einstein equations can be reduced to the standard Maxwell-type field equations in a medium; in such a context the Cerenkov emission by a neutral particle gives large energy loss while the particle moves at faster than the phase speed of waves in the medium. It has often been noted that magnetism can be understood as the consequence of ...

Simulated data were used to investigate the relationships between image properties and change detection accuracy in a systematic manner. The image properties examined were class separability, radiometric normalization and image spectral band-to-band correlation. The change detection methods evaluated were post-classification comparison, direct classification of multidate imagery, image differen...
