Development and management of software product families is an emerging and important area of software engineering, whereas product configuration of traditional, i.e., mechanical and electronic, product families has a slightly longer history as a specific area of research and business. This paper describes work in progress on the management of configurable software product families. Solutions to...

We have measured the left ventricular (LV) end-systolic (ES) pressure-area product in 30 patients under general anaesthesia. We multiplied systolic arterial pressure with the ES cavity area obtained by transoesophageal echocardiography, and compared the product with M-mode derived ES wall stress before and during cardiovascular treatment. To attain appropriate mean arterial pressure during majo...

Introduction By expanding markets and diversifying products from the desired local product, "One Village, One Product" strategy, taking advantage of the regionchr('39')s potential in the competitive market.  Utilizing the "One Village, One Product" brand, as a global product, demonstrates pride in local culture as well as an effective economic strategy, which is intended for the development of...

  Background: This study has aimed to measure the patient dose in entire spine radiography by EOS system in comparison with the digital radiography. Methods: EOS stereo-radiography was used for frontal and lateral view spine imaging in 41 patients in a prospective analytical study. A calibrated dose area product (DAP) meter was used for calibration of the DAP in EOS system. The accuracy and pr...

Minimal self-replicating systems typically consist of three components: a product molecule, and two substrate molecules that become joined to form another product molecule. An important characteristic of self-replicating systems is the ability of the product to catalyze the formation of additional product, resulting in autocatalytic behavior. Recent advances in the area of self-replication have...

Mesoporous  MgO  microstructures  were  synthesized  using magnesium  acetate  tetrahydrate,  ammonium  oxalate  monohydrate and  Pluronic  F127  via  heating  at  40  °C  for  24  h  and  subsequent calcination. The mesoporous structure of magnesium oxide with the specific  surface  area  of  47m2 /g,  pore  volume  0.30  cm3 /g  and  the average pore size 24 nm is produced. According to ...
