compactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Prevalence of adenoma of gallbladder, ultrasonographic and histological assessment in a retrospective series of 450 cholecystectomy.
BACKGROUND Adenomyomas of the gallbladder are difficult to examine during standard ultrasound examination of the abdomen. They sometimes undergo malignant transformation and their optimal management still remains a problem. The authors have aimed to investigate the ultrasonographic and histopathological prevalence of gallbladder adenomyomas focusing on the diagnostic performance of ultrasound e...
متن کاملValue of contrast-enhanced ultrasound in the differential diagnosis between gallbladder adenoma and gallbladder adenoma canceration.
OBJECTIVES To investigate the value of contrast-enhanced ultrasound (CEUS) in the differential diagnosis between gallbladder adenomas and gallbladder adenomas canceration. METHODS CEUS data from 34 patients (25 patients with gallbladder adenomas and 9 patients with gallbladder adenomas canceration) were retrospectively analyzed, including the characteristics of contrast arrival time, time to ...
متن کاملMalignant transformation of liver adenoma: an analysis of the literature.
As adenoma in other locations, hepatic adenoma (HA) may transform into hepatocellular carcinoma (HCC) and hepatocyte dysplasia is most probably the intermediate step between both conditions. Malignant HA may appear as microscopic or macroscopic areas of HCC within the HA. These areas are typically well differentiated and without vascular extension or satellite nodules. AFP measurements are not ...
