The development of instrumentation for sequential injection analysis with a "lab-at-valve" (SIA-LAV) micro-extraction system is presented. The extractive determination of an anionic surfactant using methylene blue was selected as a model. Sample, reagents and organic solvent were sequentially aspirated into an extraction coil connected to the center of a selection valve, where extraction took p...

Microbiological characterization of frescos in four different locations (Collegio degli Augustali, Casa del Colonnato Tuscanico, Casa dello Scheletro and Casa del Gran Portale) of excavation sites of Herculaneum was carried out. The use of infrared thermography allowed detecting sample points on frescos with greatest moisture not visible to the naked eye, resulting in structural damage. The mic...

Background: In mammalian spermatozoa, motility is one of the most important parameters for evaluating the quality of the semen. From a functional point of view, motility is strongly related to the spermatozoa’s ability to manage its energy status, Thus, modulation of energy status could be translated into significant changes in motility patterns. The aim of the present study was to evaluate xyl...

BACKGROUND Little is known about the regulation of sperm motility, which is an important predictor of male fertility. However, both testicular and post-testicular factors may be involved, although the impact of the latter has been relatively poorly investigated. METHODS In semen samples from 301 young men from the general Swedish population (mean +/- SD age 18.2 +/- 0.4 years), we assessed sp...

For speech segregation, a recurrent blind separation model (BSS) is tested together with a Computational Auditory Scene Analysis (CASA) model, which is based on the localisation cue and the evaluation of the Time Delay Of Arrival (TDOA). The test database is composed of 332 binary mixture sentences recorded in stereo with a static set-up. These are truncated at 1 second for the simulations. For...

As an emerging discipline, Component-Aware System Architecting (CASA) takes advantage of the composition of reusable heterogenous architectural components developed by different people, at different time. CASA can also collaborate with component-aware requirements elicitation to strengthen component-aware requirements’ claims. However, CASA does not come for free, one of many challenges facing ...
