Transitional analysis for multi-objective operative improvement of reformate quality and hydrogen production from a naphtha catalytic reforming process.

The hydrogen produced ( ) in the Catalytic Naphtha Reforming (CNR) is important in quantity and quality, for the feedback of the process and for supplying the hydrotreatment processes in current refineries. In this work it is presented a study by process simulation using ® for finding operative transitional modes that simultaneously improve quality of the reformate and hydrogen production of the CNR. The operative conditions that were studied correspond to the recirculation ratio of hydrogen/hydrocarbon ( ), with values between 2 and 6, and the temperature (), between 450 and 525 °C, in order to determining the best operative transitional route from the initial operative state to a local improved state, applying the method of superposition of response surfaces and criteria assessment of improvement in quality and quantity of hydrogen produced.

Regional and cellular organization of the autism-associated protein UBE3A/E6AP and its antisense transcript in the brain of the developing rhesus monkey.

Angelman syndrome (AS) is a neurogenetic disorder caused by mutations or deletions in the maternally-inherited allele, leading to a loss of UBE3A protein expression in neurons. The paternally-inherited allele is epigenetically silenced in neurons during development by a noncoding transcript (). The absence of neuronal UBE3A results in severe neurological symptoms, including speech and language impairments, intellectual disability, and seizures.

Mathematical modeling for operative improvement of the decoloration of Acid Red 27 by a novel microbial consortium of and : A multivariate sensitivity analysis.

In this work, it is presented a first approach of a mathematical and kinetic analysis for improving the decoloration and further degradation process of an azo dye named acid red 27 (AR27), by means of a novel microbial consortium formed by the fungus and the bacterium . A multivariate analysis was carried out by simulating scenarios with different operating conditions and developing a specific mathematical model based on kinetic equations describing all stages of the biological process, from microbial growth and substrate consuming to decoloration and degradation of intermediate compounds. Additionally, a sensitivity analysis was performed by using a factorial design and the Response Surface Method (RSM), for determining individual and interactive effects of variables like, initial glucose concentration, initial dye concentration and the moment in time for bacterial inoculation, on response variables assessed in terms of the minimum time for: full decoloration of AR27 (R = 2.

Dimensions of reading: a study of the beliefs of language and literature preservice teachers.

This study aims to analyze the beliefs that future Language and Literature teachers hold regarding reading. This work is part of a broader research endeavor focused on the reading habits and practices of teachers in training and their role as prospective mediators since the way in which they perceive reading significantly impacts the mediation processes they undertake in their teaching practices to cultivate readers. To achieve these objectives, a multiple case study is conducted, involving interviews with 1st-year students ( = 15), 3rd-year students ( = 15), and 5th-year students ( = 15) enrolled in Language Pedagogy programs across three universities affiliated with the Chilean Council of Rectors.

The NR3C1 gene expression is a potential surrogate biomarker for risk and diagnosis of posttraumatic stress disorder.

Posttraumatic Stress Disorder (PTSD) is an anxiety disorder which occurs after a traumatic event. The NR3C1 gene codes for the Glucocorticoid Receptor, which participate in the Hypothalamic-Pituitary-Adrenal (HPA) axis and is altered in PTSD patients. To evaluate whether the NR3C1 gene expression in peripheral blood could be useful as a diagnosis biomarker, a total of 32 PTSD patients and 59 healthy controls were analyzed with quantitative RT-PCR.
