When performing quality assurance, software engineers are confronted with commonand recurring defects. To detect these defects, they typically exercise their knowl-edge and experience to create test cases or use test selection strategies encapsulatingknowledge in experience. For such test selection, there is at least anecdotal evidenceof its effectiveness. The problem is its usa...

“Quality is never an accident; it is always the result of intelligent effort” [10]. In the process of making quality software product, it is necessary to have effective defect prevention process, which will minimize the risk of making defects /errors in software deliverables. An ideal approach would involve effective software development process with an integrated defect prevention process. Thi...

We report 127 cases who have had elective operation on cranium because of skull bone defect during 1984-1989. Usually repair of skull bone defect and preserving normal anatomy were the major therapeutic goals. 10, II In these cases a new surgical technique is described which can successfully accomplish these goals in a single but staged operative procedure.

Reconstructing scalp defects can be challenging for a plastic surgeon. For this purpose, different procedures such as primary repair and coverage with skin grafts or flaps can be considered. Sometimes, the external table of the skull can be removed completely to the diploic space. At the same time or after the formation of granulation tissue, the diploic space can be covered with split-thicknes...

The defect containment measure is traditionally used to provide insight into project success (or lack thereof) at capturing defects early in the project life cycle, i.e., the time when defect repair costs are at their minimum. Although the measure does provide insight into the effectiveness of early defect capture techniques (such as peer reviews), defect containment in its most common form (pe...

we have reviewed the medical records of 40 patients with disseminated (bacille calmette-guerin) bcg from 1996 to 1999 in the immunology department of the children hospital, medical center, tehran university. these patients are divided in to 3 groups: 1. patients who had disseminated (bacille calmette-guerin) bcg after vaccination and their diagnosis was chronic granulomatous disease. 2. patient...

the purpose of the present randomized clinical trial study was to compare the effectiveness of bovine porous bone mineral (bpbm) with and without plasma rich in growth factors (prgf) in the treatment of mandibular class ii furcation defects.in seven patients, nine pairs of symmetric buccal or lingual mandibular class ii furcation defects were treated. in each patient, one defect received bpbm (...

color -blindness is the inability to perceive differences between some color that other people can distinguish. using a literature search , the results indicate the prevalence of color vision deficiency in the medical profession and its on medical skills. medical laboratory technicians and technologists employees should also screen for color blindness. this research aimed to study color blindne...

In this paper, an atomistic based finite element model is developed to investigate the influence of topological defects on mechanical properties of graphene. The general in-plane stiffness matrix of the hexagonal network structure of graphene is found. Effective elastic modulus of a carbon ring is determined from the equivalence of molecular potential energy related to stretch and angular defor...
