This paper presents a case study on the factors that influence the initial adoption of Open Source Software (OSS) in a large South African organization when implementing an OSS PBX platform. The theoretical foundation for this research draws on a number of academic frameworks and models, thus not only providing a practical illustration but also validating their usefulness in guiding OSS adoption.

During limb development, expression of the TALE homeobox transcription factor Meis1 is activated by retinoic acid in the proximal-most limb bud regions, which give rise to the upper forelimb and hindlimb. Early subdivision of the limb bud into proximal Meis-positive and distal Meis-negative domains is necessary for correct proximo-distal (P-D) limb development in the chick, since ectopic Meis1 ...

Background. Pulmonary nocardiosis (PN) is an uncommon infection often seen in immunocompromised patients. Definitive diagnosis depends on identification of the organism by culture in a patient with a clinical presentation suggestive of PN. As Nocardia can grow slowly and other infections can present similarly in the immunocompromised patient, we sought to find the performance of respiratory sam...

A continuum thermomechanochemical model of the behavior of a plastic-bonded explosive PBX 9501 formulation consisting of the energetic crystal octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine HMX embedded in a polymeric binder is developed. Our main focus is on the study of the ↔ phase transformations PTs in crystalline HMX under a complex pressure-temperature path. To reproduce the pressure-te...

OBJECTIVE Accuracy of biopsy scheme depends on different parameters. Prostate-specific antigen (PSA) level and digital rectal examination (DRE) influenced the detection rate and suggested the biopsy scheme to approach each patient. Another parameter is the prostate volume. Sampling accuracy tends to decrease progressively with an increasing prostate volume. We prospectively observed detection c...
