Assessments of tracheal diameter (TD) are important to select proper endotracheal tubes. Previous studies have used X-ray and physical indices to estimate tracheal diameter but these may not reflect the actual TD. We compared TD measured by X-ray (TD-XP) and by computer tomography (TD-CT) in 200 patients. Also, we analyzed correlation of TD-CT with physical indices such as age, height, weight, ...

The resistance of tumor cells to chemotherapeutic agents, such as cisplatin,is an important problem to be solved in cancer chemotherapy. One of the mechanisms associated with cisplatin resistance is nucleotide excision repair (NER). There are two pathways in NER, transcription-coupled NER (TC-NER) and global genome NER (GG-NER). Here, we report that TC-NER-deficient cells [xeroderma pigmentosum...

Software organizations are progressively adopting the development practices associated with the Extreme Programming (XP) methodology. Most reports on the efficacy of these practices are anecdotal. This paper provides a benchmark measurement framework for researchers and practitioners to express concretely the XP practices the organization has selected to adopt and/or modify, and the outcome the...

Agile Software-Entwicklungsmethoden, und speziell Extreme Programming (XP), haben große Aufmerksamkeit unter Praktikern und Forschern auf sich gezogen. Dieser Artikel bietet eine Gesamtschau der bis jetzt bekannten, empirischen Erkenntnisse zu XP, mit dem Ziel, dem Praktiker fundierte Entscheidungshilfen zu bieten sowie die Lücken in der wissenschaftlichen Untersuchung aufzuzeigen. Verhältnismä...

Extreme Programming (XP) is an agile software development methodology defined through a set of practices and values. Although the value of XP is well-established through various real-life case studies, it lacks practices for project management. In order to enable XP for larger projects, we provide the rolling forecast practice to support product planning, and an optimization model to assist in ...
