During maintenance, software systems undergo continuous correction and enhancement activities due to emerging faults, changing environments, evolving requirements, making this phase expensive time-consuming, often exceeding the initial development costs. To understand manage under maintenance better, several maintainability measures have been proposed. The Maintainability Index is commonly used...

Siempre se ha venido señalando que la escultura vallisoletana sufrió un periodo de acusada decadencia durante el siglo XVIII, afirmación matizable sin duda debe al escaso conocimiento y falta investigación misma, dado escuela contó con maestros tan destacados como Pedro Ávila (1678-1755), Sierra (1702-1761) Felipe Espinabete (1719-1799). Hoy presentamos a interesantísimo escultor, casi desconoc...

Abstract Microorganisms have been reported to induce settlement in various marine invertebrate larvae but their specificity of inductive capacities for the coral remains poorly understood. In this study, we isolated 56 microbial strains from crustose coralline alga (CCA) Hydrolithon reinboldii using five different media either with or without additional antibiotics and/or spiked CCA extract. We...

Levansucrase (EC 2.4.1.10) was purified approximately 40-fold from the extracellular culture fluid of Erwinia herbicola NRRL B-1678. The purified enzyme in its native form occurred as an aggregate. Poly(acrylamide) gel electrophoresis in the presence of sodium dodecyl sulfate showed an active monomer having a molecular weight of 48,000. The enzyme had a K m for sucrose of 28mM and a pH optimum ...

The HADES first level trigger is studied for the system p+Ni at a beam energy of 2 AGeV. The timing properties of the trigger signal are reported. The efficiency loss due to deadtime is specified. A trigger requirement of a time overlap window with the start detector is described. The trigger rates for different overlap windows are given.

When a software system evolves, new requirements may be added, existing functionalities modified, or some structural change introduced. During such evolution, disorder may be introduced, complexity increased or unintended consequences introduced, producing rippleeffect across the system. JHotDraw (JHD), a well-tested and widely used open source Javabased graphics framework developed with the be...

BACKGROUND Influenza can cause significant morbidity and mortality in subjects at high risk for complications, including the elderly (age >or=65 years) and those with chronic respiratory, cardiovascular, or metabolic conditions. Effective prophylaxis can significantly reduce the disease burden in this population. Previous studies conducted primarily in non-high-risk subjects have reported the e...
