The mechanisms of carbon and nutrient removal in an open algal-bacterial biofilm reactor and an open bacterial biofilm reactor were comparatively evaluated during the treatment of centrates and domestic wastewater. Comparable carbon removals (>80%) were recorded in both bioreactors, despite the algal-bacterial biofilm supported twice higher nutrient(More)
The potential of a pilot high rate algal pond (HRAP) interconnected via liquid recirculation with an external absorption column for the simultaneous removal of H2S and CO2 from biogas using an alkaliphilic microalgal-bacterial consortium was evaluated. A bubble column was preferred as external absorption unit to a packed bed column based on its ease of(More)
Smartcards and PKCS #11 are an appealing solution for combined storage and certificate management at the enduser level. Many applications use PKCS #11 primitives for security reasons: a popular browser, like Netscape Navigator contain a PKCS #11 cryptographic module that plays a critical role in secure web surfing and e-mail signing and encryption.(More)
The aim of the study was to identify predictors associated with a lower likelihood of achieving a clinical remission 1 year after the first break of the illness. Participants were 174 consecutive subjects included in a first episode programme with no prior treatment with antipsychotic medication. Patients were assigned to haloperidol, olanzapine or(More)
This study investigated near-infrared spectroscopy (NIRS) to rapidly estimate physical and mechanical properties of No. 2 2 × 4 southern pine lumber. A total of 718 lumber samples were acquired from six mills across the Southeast and destructively tested in bending. From each piece of lumber, a 25-mm-length block was cut and diffuse reflectance NIR spectra(More)
Projecting multi dimensional data to a lower dimensional visual display is a commonly used approach for identifying and analyzing patterns in data. Many dimensionality reduction techniques exist for generating visual embeddings, but it is often hard to avoid cluttered projections when the data is large in size and noisy. For many application users who are(More)
We describe a combined macro and microscopic criteria for rapid presumptive differentiation between Mycobacterium tuberculosis complex (MTC) and nontuberculous mycobacteria (NTM) evaluated by two independent observers. This strategy achieved rapid MTC identification in most cases (95.8% expert observer and 91.6% novice observer) with significant savings(More)
MAPREX is a software application for process condition monitoring based on the Self-Organizing Map (SOM) neural network. It provides advanced monitoring tools in a highly versatile way, allowing to look for the causes of a system malfunction or the factors which have an influence in the final product quality in complex systems as a previous stage for(More)
