Although both ferromanganese and calcareous nodules are common in hydromorphic soils, their joint presence has rarely been evaluated.Studying their occurrence in soils forming toposequences may significantly contribute to a better understanding of their formation.We investigated the relationship between their formations in four soil profiles from a
Abstract Background Ependymomas are neuroectodermal tumors that grow from the ependymal cells of the ventricles or the central canal of the spinal cord.When the ependymoma is anaplastic, extramedullary, intradural Right Shroud and multifocal, it is a very rare anatomical entity, same as case described by us.Case presentation A 44-year-old man had b
Problem.When studying the work processes that occur in pneumatic or electropneumatic circuit of brake systems or pneumatic suspension systems of a wheeled vehicle, researchers use various expenditure functions on the basis of which they draw scientific conclusions and obtain scientific results, while they do not think about the fact that the functi
The state of the art in the evolution of plant viruses allows the genetic foundations of antiviral immunity in higher (including the most important crops) plants to be categorized as one of the most pressing issues of genetics and selection.According to the endosymbiotic theory, mitochondria descended from alphaproteobacteria that had been absorbed
The anadromous Atlantic salmon undergo a preparatory physiological transformation before seawater entry, referred to as smoltification.Key molecular developmental processes involved in this life stage transition, such as remodeling of gill functions, are known to be synchronized and modulated by environmental cues like photoperiod.However, little i
