Podcast Radiofónico de Entretenimiento Edición Especial “El Desguace Literario”

El presente proyecto creativo titulado “Podcast radiofónico de entretenimiento edición especial El Desguace Literario” propone, a modo de contenido en formato audio, una serie de espacios locutados cuya temática principal es la literatura, presentado, a su vez, en un programa radiofónico de 120 minutos aproximadamente de duración. Para entender mejor a qué nos estamos refiriendo exactamente y apoyándonos en el diccionario Oxford de lengua inglesa, podríamos definir “ podcast ” como: “ A digital audio file made available on the Internet for downloading to a computer or mobile device”, cuya traducción al castellano sería: Archivo de audio digital disponible en Internet para su descarga en ordenador o servicio móvil.No obstante, la razón de ser de este proyecto es, como indica su nomenclatura, la de crear un podcast de radio. Por tanto el objetivo principal de dicho proyecto es, en primer lugar, la garantía de que este seguirá estando disponible en la plataforma de almacenamiento y gestión correspondiente, en este caso Ivoox, para su escucha o descarga futura, pudiendo acceder a él en el momento elegido por el usuario, siendo esta una de las principales carácteristicas del servicio “podcast” Una vez planteado el formato y su disposición al público, avanzamos hasta el objetivo central siendo este la temática. Esta edición o este espacio, a diferencia del resto de capítulos de “El Desguace”, gira en torno a la literatura, por tanto todas las secciones y contenidos que en ella se traten abordarán la vida y obra de algunos de los más famosos literatos de nuestra historia.Universidad de Sevilla.

Neuraminidase-activated microglia compromise the viability of ependymocytes

Neuraminidase (NA) is a sialidase present in the envelope/wall of some virus/bacteria responsible for brain infections, such as flu, mumps or meningitis. The intracerebroventricular injection of NA in the rat brain provokes ependymal detachment and death, and an acute inflammatory process. Although inflammation reverses, ependymal lining is not regenerated. Complement system activation within the CSF contributes to ependymal damage, but is not the only cause (Granados-Duran et al, 2016). Here we aimed to investigate if microglial activation might also play a role. For this purpose we used pure isolated ependymocytes (Grondona et al, 2013) and ventricular wall explants, which were co-cultured with microglial cells, both in basal conditions and with agents that induce microglial activation: NA, LPS, or Pam3CSK4 (synthetic lipopeptide). The viability of the ependymal cells was assessed by trypan blue exclusion. The viability of isolated ependymocytes was reduced when NA or LPS were added to the culture, compared to controls without additives. In the absence of microglia, NA or LPS did not compromise viability significantly, indicating that microglia was involved in ependymocytes death. The addition of NA to cultured explants reduced ependymocytes viability only when microglial cells were present in the culture; a similar reduction was observed when LPS or Pam3CSK4 were added. Conversely, explants cultured in the absence of microglia did not suffer a significant decrease in ependymocytes viability upon NA addition to the medium. We hypothesized that cytokines released by activated microglia, such as IL1β or TNFα, could mediate ependymocytes death. RT-PCR performed in RNA obtained from pure ependymocytes confirmed the presence of IL1β and TNFα receptors in ependymal cells. Nevertheless further experiments are required to confirm this hypothesis. We conclude that microglia activated by NA mediates, at least in part, ependymal cell death, what might be relevant for neuroinflammatory diseases mediated by NA bearing virus/bacteria.Universidad de Málaga.

Perfectionism and affect as determinants of self-perceived motor competence in primary school children

The aim of this study was to analyze the primary school students’ perception of their motor competence in the area of Physical Education, with respect to the affective domain and improvement. The sample consisted of 428 primary school students aged between 8 and 12 years (M=10.43; SD=0.837) (Castilla La Mancha, Spain). Perceived motor competence (PMC) was measured by the Perception of Competence Questionnaire (POC); perfectionism was measured by the three subscales of the Child Perfectionism Questionnaire, and, finally, affectivity was assessed by the PANAS (Positive and Negative Affect Schedule) questionnaire. Positive correlations were obtained between all the dimensions of the PMC and self-improvement (p<.05). Significant gender differences were found in the PMC dimension Peers and Self-Experience, with higher scores in males (p<.05). Differences were also found in the PMC dimension Peers as a function of weight status, being lower in the overweight group (p<.05). Age was related to self-experience being higher the older one was (p<.05). A model was generated that explained 23.7% of PMC with the total dimension of self-improvement and weight status. Three distinct profiles, called high, medium and low self-improvement, were detected. These groups in turn showed an analogy in perceived motor competence, high, medium and low, the result also obtained in the regression analysis (p<.05). These results extend the relationship between perceived motor competence and self-improvement in primary school children and are potentially of interest to the fields of education and psychology

Agent Programming in Ciao Prolog

The agent programming landscape has been revealed as a natural framework for developing “intelligence” in AI. This can be seen from the extensive use of the agent concept in presenting (and developing) AI systems, the proliferation of agent theories, and the evolution of concepts such as agent societies (social intelligence) and coordination

Kinetic synergistic effect in co-pyrolysis of Eucalyptus globulus with high and low density polyethylene

The pyrolysis of Eucalyptus globulus (EG) with different blends of high density polyethylene (HDPE) and low density polyethylene (LDPE) by thermogravimetry has been studied. ASTM-E1641-16 standard method has been used to evaluate the kinetics during the pyrolysis of the studied blends. For all feedstocks (EG, HDPE and LDPE) and blends studied, the relative content (%) of the volatile organic compound has been determined by GC–MS analysis. Different synergistic effects on the activation energy of EG blends with HDPE and LDPE have been found. EG-HDPE blends showed a minimum activation energy (Ea) (125 kJ mol−1) at the 80% EG–20% HDPE ratio, while the minimum Ea value for EG-LDPE blends was found at the 60% EG–40% LDPE ratio (135 kJ mol−1) has been identified. To test which components exert a greater synergistic effect, mixtures of HDPE and LDPE with the main components of eucalyptus (cellulose, hemicellulose and lignin) have also been studied. However, no synergistic effects on the pyrolysis of cellulose have been detected. Moreover, in hemicellulose and lignin with both types of polyethylene mixtures, a significant decrease in Ea has been appreciated. The lowest Ea values for 60% cellulose–40% HDPE (167 kJ mol−1) and 60% lignin–40% HDPE (140 kJ mol−1) has been calculated. On the other hand, minimum values for 40% cellulose–60% LDPE (166 kJ mol−1) mixture and for 40% lignin–60% LDPE (168 kJ mol−1) mixture have been detected. Thus, the decrease in both Ea and the Arrhenius pre-exponential factor on the eucalyptus-polyethylene blends to the presence of hemicellulose and lignin can be attributed. Moreover, during the co-pyrolysis of HDPE-EG mixtures, n-paraffins, ketones, phenols and sugars are the main VOCs identified. In contrast, in LDPE-EG mixtures, only n-paraffins (55%) and olefins (44%) have been identified.This study received financial support from Green Asphalt project (ref. 802C1800001) co-funded 80% by FEDER European Programme and 20% by the Regional Government of Andalusia (Agency for Innovation and Development of Andalusia (IDEA) and (Operational Programme FEDER Andalusia 2014–2020, Project UHU–1255540), Spain.

Ultrasound extraction optimization for bioactive molecules from Eucalyptus globulus leaves through antioxidant activity

Antioxidant products present a very high added value and are demanded in the market. The optimization of their extraction is a high-stakes matter for both economic and environmental points of view. Ultrasound extraction has been considered one of the most promising methods, so the relative importance of key parameters may have decisive economic significance. For this reason, different parameters that have influence on the extraction capacity such as ultrasound power, time, temperature, pH and % ethanol in water have been studied to know the relationships between the independent parameters and their influence on the extraction from Eucalyptus globulus leaves. An experimental Box-Behnken factorial design and subsequent analysis by neural networks have been used. The relative influence of each parameter varies according to the nature of the extracted compound. In this regard, the higher capacity of extraction of the selected antioxidant compounds by means of the variation of the operation conditions can be facilitated. For all the studied compounds, temperature has been the most important parameter for their extraction. The relative content (%) of bioactive compounds (terpenes) in the optimized Eucalyptus globulus extract has been performed by GC–MS analysis

Optimization of bioactive compounds by ultrasound extraction and gas chromatography - mass spectrometry in fast-growing leaves

Fast-growing crops are of great economic importance in the production of paper pulp and energy. The commercialization of the bioactive components from underutilized parts could provide additional value to these crops. In the present study, chromatography gas coupled to mass spectrometry triple quadrupole (GC–MS/MS) and ultrasound extraction technique was used in the bioactive compounds determination in fast-growing crops leaves. Twenty-one terpenes and eight polyphenolic bioactive compounds were studied. Prior to GC–MS/MS, polydimethylsiloxane (PDMS) - stir bars preconcentration and trimethylsilane (TMS) derivatization steps were used for terpenes and polyphenolic compounds, respectively. Several parameters (pH, temperature, ethanol–water mixtures, ultrasound power, and ultrasound time) of the extraction step were optimized by central composite experimental design. Ethanol content, ultrasound power, and ultrasound time were the parameters that most influence the extraction efficiency of terpenes in biomass residues, while for polyphenolic compounds it was temperature and ultrasound time. The optimal ultrasound extraction conditions for terpenes were 60% ethanol, pH 4, 80 W, 40 ºC, and 15 min, whereas for polyphenolic compounds they were 60% ethanol, pH 4, 120 W, 50 ºC, and 15 min. The detection limits (LOD) were in the range of 0.200–3.02 µg kg−1 and 7.9–540 µg kg−1 for terpenes and polyphenolic compounds, respectively. The developed analytical method was applied to twelve fast-growing leaves (Leucaene (diversifolia and leucocephala), Eucalyptus (globulus and urograndis), Populus (I214 and AF2), Prosopis (alba and juliflora), Robinia, Tagasaste, Ulmus pumila, and Paulownia). Eucalyptol was the mayor terpene present in all the plants studied, while chlorogenic and quinic acid were the mayor phenolic compounds.This study was supported by the Ministry of Economy and Competitiveness (Spain), as well as by the National Research Program Oriented to the Challenges of Society (Project PID2020-112875RB-C21 funded by MCIN/AEI /10.13039/501100011033), and the Ministry of Innovation, Science and Business of the Government of the Junta of Andalusia (Spain), the Operative Program is framed within FEDER Andalusia 2014–2020 (Project UHU-125540).

Root length density (RLD) of oil palm (Elaeis guineensis Jacq) in a haplic Luvisol in Chiapas, Mexico

The tight relationship between root architecture and uptake capacity of soil water and minerals, is well established. Support roots, generally long-lived, perform support functions such as transportation and food storage. Absorbing roots, thin and short-lived, absorb nutrients and regulate plant metabolism. Roots distribution in the soil profile is crucial for plant development. It optimizes resource usage and ensures a prompt response to seasonal changes. This work aimed to study the vertical distribution of the root system of nine-year-old oil palms in a haplic Luvisol, low fertility, moderately acidic, with Nitrogen (N) and Potassium (K) deficiency, average content of Phosphorous (P), and medium to low Cation Exchange Capacity (CEC). Using the cylinder method, soil samples were collected every 10 cm and down to 150 cm of soil depth, from each cardinal side of three soil profiles. The results showed that oil palms had good root development. Most roots (73%) were found in the first 30 cm of soil, with a predominance of fine roots (78%). At 50 cm in depth, fine roots represented 88%, thin roots, 67% and medium roots, 94%. Further study should assess root length density at 15, 20, 25, and 30 years. Highlights - Haplic luvisols are optimal soils for oil palm cultivation due to their depth (&gt; 150cm), over 50% base saturation, and pH of 5.5-6.6. - Root length density (RLD) decreased as soil depth increased. Although most oil palm roots are found in surface horizons, roots can still be found at depths of up to 1.5-5 m. - The highest number of oil palm roots (73%) was found in the first 30 cm, with 78% of fine roots. - Fine roots were distributed throughout the entire soil profile, evidencing  high nutrient-absorption and metabolic activities.The tight relationship between root architecture and uptake capacity of soil water and minerals, is well established.
