A bstract We study gravitational collapse for the Starobinsky R 2 model, a particular example of an f ( r ) theory, in spherically symmetric spacetime. add massless scalar field as matter content to work Einstein frame, where additional arises due conformal transformation. As general relativity, depending on initial data, we found that gravity and physical can collapse, forming black hole, whic...

The low-molecular weight beta-trace protein constitutes about seven per cent of the total protein content in human cerebrospinal fluid. Within the central nervous system the protein is found predominantly in white matter and fractions enriched in glial cells. Immunofluorescence studies on sections of monkey brains show that beta-trace protein is particularly localized to cells such as astrocyte...

OBJECTIVES To study the value of assessing renal masses using different methods in parameter approaches and to determine whether BOLD MRI is helpful in differentiating RCC from benign renal masses, differentiating clear-cell RCC from renal masses other than clear-cell RCC and determining the tumour grade. METHODS Ninety-five patients with 139 renal masses (93 malignant and 46 benign) who unde...
