background: in vitro model studies are becoming increasingly popular for experimental research designs. they include isolation and expansion of cells of a particular tissue, such as the nervous tissue which contributes to understanding the underlying mechanisms in many pathologies. it enables  the scrutinization of intracellular signaling pathways responsible for cell death. objectives: in the ...

Introduction: Psychological stresses influence brain functions such as learning and memory. Environmental factors like types and durations of stress affect brain responsiveness. This study investigated the effects of two subchronic social and isolation stresses on learning, memory, adrenal glands weight and corticosterone levels in the hippocampus and frontal cortex. Methods: Eighteen male ...

The problem of fault detection and isolation in complex chemical/biochemical plants can be effectively addressed by a hierarchical strategy involving successive narrowing of the search space of potential faults. A bond graph network is one means of achieving a decomposition based on a separation of the physical domains such as mechanical, electrical, etc. In this work, bond graph theory is used...

At Schlumberger RPS, the application of the Goal/Question/Metric approach (GQM) and the Quality Improvement Paradigm (QIP) resulted in an enhanced ‘model-based GQM’. It customizes measurement to the organization and supports in the reuse of experience, by applying and maintaining reusable reference models. This ‘model-based GQM’ is a more formal method for the application of software measuremen...
