Predictive analysis of the value of information flow on the shop floor of developing countries using artificial neural network based deep learning.

To facilitate the continuous improvement of performance and the management of information flow (MIF) for production and manufacturing purposes on the shop floor of developing countries, there is a need to characterize information flow that will be shared during the process. MIF provides a key performance shop floor metric called the value of information flow (VIF). Previous methods have been used to analyze VIF in developed countries.

Superior vena cava tumoral thrombosis revealing a Burkitt's lymphoma and a lymphoblastic non-Hodgkin's lymphoma. A case report.

Superior vena cava thrombosis (SVCT) is a rare pathology, though of great significance since it implies the development of a malignant process. The most common etiologies are basically bronchopulmonary and mediastinal tumors. Observations involving 2 patients presenting with superior vena cava syndrome (SVCS) are reported in this study, in which radiologic investigations (chest roentgenogram, computed tomography scan of the thorax, and superior vena cavography) revealed thrombosis of the SVC disclosing in both cases a non-Hodgkin's lymphoma.

We propose through the retrospective analysis of this document, to explain the inefficiency of the action of chemo and radiotherapy on tumours with a high proliferation coefficient but which are however known to be highly sensitive as well as curable with chemo and radiotherapy. This study shows the technical conditions and dispositions for a better therapeutic approach in these tumours with a rapid growth.
