in this paper we study the existence of commuting regular elements, verifying the notion left (right) commuting regular elements and its properties in the groupoid g(n) . also we show that g(n) contains commuting regular subsemigroup and give a necessary and sucient condition for the groupoid g(n) to be commuting regular.
La grelina es principalmente un péptido secretado en el estómago que actúa sobre sistema nervioso central para regular metabolismo energético y las respuestas al estrés. En pollo disminuye la ingesta de alimentos se ha sugerido hormona liberadora corticotropina podría mediar esta respuesta. presente estudio estudia si anorexia inducida por intra-mesopallium involucrar activación del eje hipotal...
We give lower bounds on the largest singular value of arbitrary matrices, some of which are asymptotically tight for almost all matrices. To study when these bounds are exact, we introduce several combinatorial concepts. In particular, we introduce regular, pseudo-regular, and almost regular matrices. Nonnegative, symmetric, almost regular matrices were studied earlier by Ho¤man, Wolfe, and Ho¤...
intraepiphyseal location of an osteoid osteoma is extremely rare with few cases reported in the literature. they are often present with various atypical and nonspecific clinical features. synovitis of adjacent joint is common and along with chronic inflammation could be misinterpreted as rheumatoid arthritis. initial plain radiographs are often not diagnostic and further radiologic evaluation w...
AIM We studied several ultrasounds patterns concerning gallbladder, biliary tract and gallstones to identify some predictive signs of difficulties during LC. PATIENTS & METHODS 112 patients (24 females), 25-75 years old, upper abdomen operated patients not included. From 7 ultrasounds patterns 4 degrees of potential intra-operative difficulty (0-3) were obtained. During the operation 7 condit...
AIM The present study was aimed to investigate the relationship of udder shape, teat-end shape, teat length, and teat diameter with intra-mammary infection in Jersey crossbred cows under hot-humid climate. MATERIALS AND METHODS A total of 24 lactating Jersey crossbred cows were evaluated for udder shape (pendulous/regular) and teat-end shape (flat/inverted/pointed) by visual examination, whil...
In this article we study two different generalizations of von Neumann regularity, namely strong topological regularity and weak regularity, in the Banach algebra context. We show that both are hereditary properties and under certain assumptions, weak regularity implies strong topological regularity. Then we consider strong topological regularity of certain concrete algebras. Moreover we obtain ...
INTRODUCTION In acute ischemic stroke, imaging of the cranio-cervical vessels is essential for intra-arterial treatment selection. Fast, reliable and easy accessible imaging is necessary 24 hours a day, 7 days a week. Radiologists in training and non-expert readers often perform initial reviewing. In this pilot study, the potential benefit of adding 4Dimensional-CT Angiography (4D-CTA) to the p...
The yeast Saccharomyces cerevisiae exhibits sustained oscillations under noise-free controlled conditions in continuous cultures. The regular periodicity of the oscillations and synchrony between different metabolic variables may be described by mathematical models and model-based control. Large bioreactors, however, are prone to disturbances or noise in the feed stream, which may alter the osc...
