TL;DR: In this article, the DISS facility is described, followed by an explanation of the main control problem, and control schemes for one of the three operating modes, the once-through mode, are discussed, including system models, feedforward blocks, and PI blocks.
Abstract: This article describes the DISS facility, followed by an explanation of the main control problem. The control schemes for one of the three operating modes, the once-through mode, are then discussed, including system models, feedforward blocks, and PI blocks. Finally, experimental results and conclusion are presented.

TL;DR: A higher CR score is associated with better performance in almost all tests employed and has a significant contribution to performance on verbal fluency, behavioral spontaneity, reasoning, divided and complex attention, and working memory functions, which are mainly related to the dorsolateral prefrontal area.
Abstract: The main objective of this research was to establish the relation between age, cognitive reserve (CR), and attentional and executive functions. One hundred and sixty healthy participants aged 20 to 65 years old completed a wide battery of frontal-lobe tasks using classical tests that assess planning and control of movement, problem solving, and inhibition of automatic response, visuomotor tracking, focused and sustained attention, shifting, spontaneity and reasoning. The total sum of the score in premorbid IQ (by means of the Weschsler Adult Intelligence Scale Vocabulary subtest), educational level, and type of profession was used as a proxy of CR. Subjects were divided into groups of low or high CR. Multiple linear and logistic analyses revealed that age is a predictor of the 20Q Test, Terman Merril's Picture task, Similarities, Digit Span (backward), Trail-Making Tests, Porteus Maze Trace, the "A" Letter Cancellation Test, and reciprocal inhibition. CR is a predictor of the Controlled Oral Word Association Test, Trail-Making Tests A and B, Digit Span (forward), and Similarities. In conclusion, a higher CR score is associated with better performance in almost all tests employed. But it has a significant contribution to performance on verbal fluency, behavioral spontaneity, reasoning, divided and complex attention, and working memory functions, which are mainly related to the dorsolateral prefrontal area.

TL;DR: The multiresidue method has been applied to the analysis of 178 vegetable samples, as a part of the monitoring programme of the Association of Producers and Exporters of Fruits and Vegetables of Almería and quality control systems applied during the assays have demonstrated a good performance and stability with time.
Abstract: A multiresidue method is described for determining 55 organophosphorus and organochlorinated compounds and pyrethroids commonly used in crop protection. Pesticide residues are extracted from samples with a mixture of ethyl acetate and sodium sulfate, obtaining a final preconcentration of 1 mg sample (ml extract)−1. No additional clean-up steps are necessary. Analysis is performed by gas chromatography by using a combination of positive chemical ionisation (PCI) and electron impact (EI) ionisation modes and tandem mass spectrometry (GC-PCI/EI-MS-MS). Good sensitivity and selectivity of the method are obtained with limits of detection (LODs) ranging from 0.07 to 4.21 μg kg−1 in all the cases, except for methamidophos, permethrin, cypermethrin and difenconazol. Average recoveries between 52 and 114% are obtained and good linearity is observed in the studied ranges (r
0.994). The RSD values are ⩽29% in all the cases. The

TL;DR: In this paper, the effect of inoculating three native Nfixing species (Nostoc commune, Scytonema hyalinum, and Tolypothrix distorta), individually and as a consortium, on soil properties from three different semiarid ecosystems in southeast Spain was analyzed.
Abstract: In recent years, soil inoculation with cyanobacteria has become one of the most promising biotechnological strategies for restoring soil functionality in degraded drylands because of their critical role in increasing soil fertility and preventing erosion. Nevertheless, in order to fully exploit this biotechnology on a large scale, it must still be shown whether inoculated cyanobacteria are capable of developing in soils with different physicochemical properties, and new candidates adapted to desert conditions must be explored. To evaluate the potential of cyanobacteria for restoring soil functions of degraded dryland soils, in this laboratory study, we analyzed the effect of inoculating three native N‐fixing species (Nostoc commune, Scytonema hyalinum, and Tolypothrix distorta), individually and as a consortium, on soil properties from three different semiarid ecosystems in southeast Spain. The biocrust colonization was monitored by determining chlorophyll a content (the typical surrogate used for biocrust biomass). Other methodologies, such as the analysis of soil spectral response and image classification were also applied for cover estimation of the biocrust. After 3 months, all inoculated soils showed cyanobacteria cover of up to 50%, lower albedo and higher chlorophyll a content. Cyanobacterial inoculation also improved soil functions, as they promoted a significant gain in total organic carbon and total nitrogen in all soils. Among inoculation treatments, Nostoc commune and the mixture of all three species promoted the most cyanobacteria coverage, chlorophyll content, and surface darkening, as well as organic carbon and total nitrogen gains in the soil, highlighting their excellent performance in biocrust development.
