Performing operational release planning, re-planning and risk analysis using a system dynamics simulation model

Software release planning takes place on strategic and operational levels. Strategic release planning aims at assigning features to subsequent releases such that technical, resource, risk and budget constraints are met. Operational release planning focuses on the development of a single software release. Its purpose is to assign resources to feature development tasks such that total release durati

The use of N-terminal pro-brain natriuretic Peptide to evaluate vascular disease in elderly patients with mental illness.

BACKGROUND: Serum N-terminal pro-brain natriuretic peptide (NT-proBNP) is regarded as a sensitive marker of cardiovascular disease. Vascular disease plays an important role in cognitive impairment. METHOD: In 447 elderly patients with mental illness, serum NT-proBNP level and the presence or absence of vascular disease according to the medical record were used to categorize patients in different

The cost of vacuum-assisted closure therapy in treatment of deep sternal wound infection.

Objectives. Surgical sites infections are very expensive and the total costs for coronary artery bypass grafting (CABG) surgery followed by deep sternal wound infection (DSWI) with conventional therapy are estimated to be 2.8 times that for normal, CABG surgery. Promising results have been reported with vacuum-assisted closure (VAC) therapy in patients with DSWI. This study presents the cost of VA

Notes on Formal Deformations of Hom-associative and Hom-Lie Algebras

The aim of this paper is to extend to Hom-algebra structures the theory of formal deformations of algebras which was introduced by Gerstenhaber for associative algebras and extended to Lie algebras by Nijenhuis-Richardson. We deal with Hom-associative and Hom-Lie algebras. We construct the first groups of a deformation cohomology and give several examples of deformations. We provide families of Ho

Survey of the management of acute pancreatitis in surgical departments in Sweden.

Objective: Several international guidelines concerning the treatment of acute pancreatitis has been published during the last decades. However, Scandinavian guidelines are still lacking. The aim of the present study is to identify current treatment strategies for acute pancreatitis in Sweden and to evaluate if there is a need for improvement and the role of guidelines. Material and methods: A qu
