This study aimed at exploring how the organizational culture can contribute in adopting Total Quality Management (TQM) in the organization. A case study was conducted at the Salt complex in El Outaya, Biskra State and the questionnaire was used to collect data. The study found that the organizational culture (organizational values, organizational behavior and the artifacts) contributes in adopt...

Reliable attenuation correction methods in PET require accurate determination of the attenuation map (μmap), which represents the spatial distribution of linear attenuation coefficients (LACs) at 511 keV for the region under study. Since CT image pixel intensities are directly related to the LAC of the corresponding tissue calculated from the effective CT energy, the μmap at 511 keV can be dire...

Biofilms, organic matter, iron/aluminum oxides, and clay minerals bind toxic heavy metal ions and control their fate and bioavailability in the environment. The spatial relationship of metal ions to biomacromolecules such as extracellular polymeric substances (EPS) in biofilms with microbial cells and biogenic minerals is complex and occurs at the micro- and submicrometer scale. Here, we review...

Introduction: The issue of metal artifact and its reduction is as old as the clinical use of computed tomography itself. When metal objects such as dental fillings, hip prostheses or surgical clips are present in the computed tomography (CT) field of view (FOV), make severe artifacts that reduce the image quality and accuracy of CT numbers. They can lead to unreliable ...
