Con enfoque de aprendizaje global: reflexionando sobre un cambio de paradigma en el modelo de comprensión por generaciones en la Educación para el Desarrollo Global. (2014)

En este articulo se propone una mirada diferente sobre la Educacion para el Desarrollo (EpD),
basada en la actualidad en el paradigma de generaciones (Korten, 1987; Ortega, 1994; Mesa,
2000). Para ello se hace un breve estudio sobre ventajas e inconvenientes en el modelo actual
y las definiciones que lo describen. A continuacion se revisa la mision de la EpD en base a una
metafora de planos y herramientas. Despues hace una aproximacion critica a las practicas en
base a la comprension y presupuestos que manejan del aprendizaje. Desde ahi elabora una
nueva aproximacion a la EpD basada en niveles emergentes que parten de la practica reflexiva
y basada en cinco elementos progresivos, volviendo a analizar el modelo de generaciones y
estableciendo relaciones y diferencias. Todo ello se concreta en un “enfoque de aprendizaje
global”, que sobrepasa las dimensiones clasicas de la EpD y pretende ayudar a pensar de una
manera mas cohesionada y coherente sus practicas y dilemas, asi como se encaje, en la mejora
de la educacion, la cooperacion al desarrollo y la sociedad en general.

Relation Between Certain Skimmilk Constituents and the Yield of Cottage Cheese (1957)

A study of the factors influencing the yield of cheese indicated there was no difference in the recovery of solids in cheese with either acid or rennet coagulation, when proper manufacturing methods were used. Recovery of total solids in cheese from milk containing 8.92% solids was 32.2%, and from that containing 9.71% solids, 38.8%. Bquations were developed to show the relationship between casein, milk solids, and yield of cheese. Editor.

Characterization and Growth-Depressing Activity for Chickens of Several Natural Phenolic Materials (1975)

Several natural phenolic materials were analyzed for gallic acid and were further characterized for dialyzability and flavonoid content. These materials were added to a diet and fed to broiler strain chicks for 4 weeks. The depression in growth caused by these phenolic materials was compared with that of tannic acid on a gallic acid equivalency basis. The activities relative to tannic acid (congruent to 100) were as follows: methyl gallate, 195; valonia, 117; wattle, 114; allepo tannic acid, 107; eucalyptus, 105, myrobalan, 98; tara crystals, 76; mangrove, 72; quebracho, 39; gallic acid, and ellagic acid, O. It was impossible to clearly relate the growth depressing activity of the materials to hydrolyzability or relative content of smaller phenols.
Density Estimation by Total Variation Penalized Likelihood Driven by the Sparsity ℓ1 Information Criterion (2010)

Abstract. We propose a non-linear density estimator, which is locally adaptive, like wavelet estimators, and positive everywhere, without a log- or root-transform. This estimator is based on maximizing a non-parametric log-likelihood function regularized by a total variation penalty. The smoothness is driven by a single penalty parameter, and to avoid cross-validation, we derive an information criterion based on the idea of universal penalty. The penalized log-likelihood maximization is reformulated as an ℓ1-penalized strictly convex programme whose unique solution is the density estimate. A Newton-type method cannot be applied to calculate the estimate because the ℓ1-penalty is non-differentiable. Instead, we use a dual block coordinate relaxation method that exploits the problem structure. By comparing with kernel, spline and taut string estimators on a Monte Carlo simulation, and by investigating the sensitivity to ties on two real data sets, we observe that the new estimator achieves good L1 and L2 risk for densities with sharp features, and behaves well with ties.

Carbon-Supported Pd-Co Alloy Electrocatalysts for Methanol Tolerant Oxygen Reduction (2007)

Carbon-supported Pd-Co bimetallic nanoparticle electrocatalysts of different Pd/Co atomic ratios were prepared by a modified polyol reduction. An activity comparison of the oxygen reduction reaction (ORR) on Pd-Co alloy catalysts with the same Pd loading, the same fcc disordered structure and a similar particle size has been made. Both composition and structure of Pd-Co alloys have a significant influence on the ORR. The change in the ORR activity with different Pd/Co compositions is correlated to their structural parameter. The maximum ORR activity for Pd2Co/C catalyst heat-treated at 500 oC is attributed to an optimal alloy composition and to a favorable Pd-Pd mean interatomic distance caused by alloy formation. Moreover, the Pd-Co alloy catalyst exhibited much higher ORR activity than the Pt/C catalyst in the presence of methanol, thus it may function as a methanol-tolerant ORR catalyst in a direct methanol fuel cell.
Equipos docentes : innovación docente en la Universidad Politécnica de Cartagena (2012-2013) (2013)

El proyecto de Equipos Docentes de la Universidad Politécnica de Cartagena (UPCT) empezó a funcionar en 2009-2010, al amparo del Programa de Redes de Investigación en Docencia Universitaria del Vicerrectorado de Ordenación Académica de nuestra Universidad. En la actualidad, el proyecto depende del Vicerrectorado de Profesorado e Innovación Docente. Aunque en algunas universidades un “equipo docente” es cualquiera de las comisiones de coordinación docente horizontal o vertical de sus titulaciones, en la UPCT se emplea esta denominación, creemos que con toda propiedad, para referirse a equipos de innovación docente, es decir a grupos de trabajo constituidos de forma voluntaria que se dedican a reflexionar sobre distintos aspectos de la actividad docente, a intercambiar experiencias y a mejorar la praxis docente de sus integrantes. Desde el curso pasado disponen de un reglamento de régimen interno que regula su funcionamiento y su reconocimiento por parte de la UPCT.
Anti‐Tumour Necrosis Factor‐α Therapy in Heart Failure: Future Directions (2006)

The elevated level of tumour necrosis factor-alpha (TNF-alpha) in patients with heart failure has triggered interest in investigating the role of TNF-alpha in the pathogenesis of heart failure. Both clinical and experimental evidence has suggested that high levels of TNF-alpha occur in heart failure and lead to progression of left ventricular dysfunction. In addition, it has been documented that inhibition of TNF-alpha reverses its deleterious effects in heart failure. A number of clinical trials have been initiated to investigate the effect of anti-TNF-alpha therapy in patients with heart failure. The discouraging results of recent clinical trials of anti-TNF-alpha therapy in patients with heart failure have raised a number of questions about the role of TNF-alpha in heart failure. The present review critically analyzes the reasons of failure of anti-TNF-alpha therapy in heart failure. Moreover the potential approaches for the development of new anti-TNF-alpha therapy has been discussed which may open new vista of the management of heart failure.
C-Type Lectin-Like Receptors of the Dectin-1 Cluster: Ligands and Signaling Pathways (2013)

Innate immunity is constructed around genetically encoded receptors that survey the intracellular and extracellular environments for signs of invading microorganisms. These receptors recognise the invader and through complex intracellular networks of molecular signaling, they destroy the threat whilst instructing effective adaptive immune responses. Many of these receptors, like the Toll-like receptors in particular, are well-known for their ability to mediate downstream responses upon recognition of exogenous or endogenous ligands; however, the emerging family known as the C-type lectin-like receptors contains many members that have a huge impact on immune and homeostatic regulation. Of particular interest here are the C-type lectin-like receptors that make up the Dectin-1 cluster and their intracellular signaling motifs that mediate their functions. In this review, we aim to draw together current knowledge of ligands, motifs and signaling pathways, present downstream of Dectin-1 cluster receptors, and discuss how these dictate their role within biological systems.

Carbonized‐MOF as a Sulfur Host for Aluminum–Sulfur Batteries with Enhanced Capacity and Cycling Life (2019)

Abstract The rechargeable aluminum–sulfur (Al–S) battery is a promising next generation electrochemical energy storage system owing to its high theoretical capacity of 1672 mAh g −1 and in combining low‐cost and naturally abundant elements, Al and S. However, to date, its poor reversibility and low lifespan have limited its practical application. In this paper, a composite cathode is reported for Al–S batteries based on S anchored on a carbonized HKUST‐1 matrix (S@HKUST‐1‐C). The S@HKUST‐1‐C composite maintains a reversible capacity of 600 mAh g −1 at the 75th cycle and a reversible capacity of 460 mAh g −1 at the 500th cycle under a current density of 1 A g −1 , with a Coulombic efficiency of around 95%. X‐ray diffraction and Auger spectrum results reveal that the Cu in HKUST‐1 forms S–Cu ionic clusters. This serves to facilitate the electrochemical reaction and improve the reversibility of S during charge/discharge. Additionally, Cu increases the electron conductivity at the carbon matrix/S interface to significantly decrease the kinetic barrier for the conversion of sulfur species during battery operation.
Attention-based Context Aggregation Network for Monocular Depth Estimation (2019)

Depth estimation is a traditional computer vision task, which plays a crucial role in understanding 3D scene geometry. Recently, deep-convolutional-neural-networks based methods have achieved promising results in the monocular depth estimation field. Specifically, the framework that combines the multi-scale features extracted by the dilated convolution based block (atrous spatial pyramid pooling, ASPP) has gained the significant improvement in the dense labeling task. However, the discretized and predefined dilation rates cannot capture the continuous context information that differs in diverse scenes and easily introduce the grid artifacts in depth estimation. In this paper, we propose an attention-based context aggregation network (ACAN) to tackle these difficulties. Based on the self-attention model, ACAN adaptively learns the task-specific similarities between pixels to model the context information. First, we recast the monocular depth estimation as a dense labeling multi-class classification problem. Then we propose a soft ordinal inference to transform the predicted probabilities to continuous depth values, which can reduce the discretization error (about 1% decrease in RMSE). Second, the proposed ACAN aggregates both the image-level and pixel-level context information for depth estimation, where the former expresses the statistical characteristic of the whole image and the latter extracts the long-range spatial dependencies for each pixel. Third, for further reducing the inconsistency between the RGB image and depth map, we construct an attention loss to minimize their information entropy. We evaluate on public monocular depth-estimation benchmark datasets (including NYU Depth V2, KITTI). The experiments demonstrate the superiority of our proposed ACAN and achieve the competitive results with the state of the arts.
Precision temperature reference for microwave radiometry (Short Papers) (1973)

The calibration of microwave radiometers is normally achieved by replacing the antenna with a cooled reference termination and then applying corrections for ohmic and reflective losses of the antenna, and for the nonideality of the reference termination. The uncertainty in this correction is the dominating factor in the precision of many high-quality radiometers, and for some applications it is unacceptably large. An alternative is to point the antenna at a target of known temperature. To the extent that this temperature is known and the target is reflectionless and encompasses the full view of the antenna, the calibration is ex'act and no further corrections are required. A target suitable for high-precision radiometry has been developed that has an accurately known radiometric temperature, a very low reflection coefficient, and whose geometry is well suited to the calibration of horn antennas. The essence of the temperature reference is described. A piece of porous microwave absorber having a convoluted surface for a low reflection coefficient is fitted with a cap of nonporous plastic foam whose mating surface is the inverse of that of the absorber. The microwave-absorbing material is then soaked with the chosen cryogen, the nonporous cap forcing the liquid to conform to the shape of said absorbing material. This procedure 1) ensures that the temperature at which the microwaves are absorbed (and therefore thermally emitted) is exactly that of the cryogen, and 2) avoids the reflection that would be produced by the dielectric discontinuity of a plane surface of cryogen.

BitAV: Fast Anti-Malware by Distributed Blockchain Consensus and Feedforward Scanning (2016)

I present the design and implementation of a novel anti-malware environment called BitAV. BitAV allows for the decentralization of the update and maintenance mechanisms of the software, traditionally performed by a central host, and uses a staggered scanning mechanism in order to improve performance. The peer-to-peer network maintenance mechanism lowered the average update propagation speed by 500% and is far less susceptible to targeted denial-of-service attacks. The feedforward scanning mechanism significantly improved end-to-end performance of the malware matching system, to a degree of an average 14x increase, by decomposing the file matching process into efficient queries that operate in verifiably constant time.
Identification of specific protein carbonylation sites in model oxidations of human serum albumin (2006)

Human serum albumin (HSA) was subjected to oxidative stress and the locations of the resulting protein carbonyls were determined using mass spectrometry in conjunction with a hydrazide labeling scheme. To model oxidative stress, HSA samples were subjected to metal-catalyzed oxidation (MCO) conditions or treated with hypochlorous acid (HOCl). Oxidation led to the conversion of lysine residues to 2-aminoadipic semi-aldehyde residues, which were subsequently labeled with biotin hydrazide. Analysis of the tryptic peptides from the samples indicates that the oxidations are highly selective. Under MCO conditions, only two of the 59 lysine residues appeared to be modified (Lys-97 and Lys-186). With HOCl, five different lysine modification sites were identified (Lys-130, Lys-257, Lys-438, Lys-499, and Lys-598). These results strongly suggest that the preferred site of modification is dependent on the nature of the oxidant and that the process relies on specific structural motifs in the protein to direct the oxidation. The high selectivity seen here provides insights into the factors that in vivo drive the selective carbonylation of specific proteins in systems under oxidative stress.
POWER TRANSFER TO HIGH SPEED VEHICLES (1992)

The final report summarizes work performed in the assessment and analysis of power transfer techniques to high speed vehicles. The objectives of the research were to determine the optimum power transfer technique for two power levels at high speed and to prepare a preliminary design of the optimum power transfer technique. The power levels are 'hotel' power and drive power. The investigation was restricted to power transfer techniques of contact and non-contact types. It is recommended that power be transferred by air-core transformer action between the stationary guideway and the moving vehicle across the full air gap. The direct current power is inverted locally by semiconductor switches operating at 1 kHz. Power factor correction is performed by a capacitor on-board the vehicle. According to a design example, approximately 1 MW can be transferred per coil across the full air gap (100 mm)) per meter of vehicle sidewall. Therefore, 40 MW can be transferred by coils on both sides of a 20 m vehicle. The major advantage of the technique is non-contact high power transfer independent of vehicle speed. The overall economics of the technique are competitive with other systems. Moreover, the concept provides performance no other concept can provide at any price.
Hydroxy-urea protects erythrocytes against oxidative damage (2000)

Hydroxy-urea (OH-U) is used to treat sickle cell anemia by increasing hemoglobin fetal-fraction. It has been suggested that the sickle cell mutations lead to the formation of unstable HbS and release of iron, which can result in lipid peroxidation (LPO), and eventual cell damage. Since oxidative processes might be involved in pathogenesis of sickle cell disease, we investigated the antioxidant property of OH-U in a red blood cell (RBC) model. Intact RBCs or RBC membranes were exposed to t-butyl hydroperoxide (t-BHP, 0.75 mM) or iron (ferrous sulfate; 100 microM) at 37 degrees C for 60 min in the presence or absence of OH-U (1.25 mM). The extent of oxidative damage was measured by LPO (as thiobarbituric acid reactive substances, TBARS), hemoglobin oxidation (as percent of methemoglobin, metHb %), and decrease in the activities of membrane-bound Na+/K+-ATPase and Ca2+-ATPases. Our results show that OH-U inhibited t-BHP-induced LPO in fresh RBC membranes significantly (P <0.01). OH-U significantly inhibited t-BHP-mediated LPO (P <0.01) and metHb formation (P <0.01) in intact RBC. Also, OH-U inhibited iron-induced LPO and metHb formation in intact RBC (P <0.01). In addition, OH-U blocked t-BHP-mediated changes in membrane ATPase activities. Furthermore, OH-U blocked iron-mediated hydroxyl radical generation in a dose-dependent fashion. In conclusion, the observed antioxidant properties of OH-U might contribute to its therapeutic action in sickle cell disease.

Studies on the chemical control of psychrophilic bacterial spoilage of fish. 3 - The effect of chemical preservatives on the growth of psychrophilic bacteria isolated from marine fish (1981)

Dehydroacetic acid and ammonia were found to be very effective in checking the growth of all the cultures at all concentrations tried. The two nitrofuran derivatives namely, semicarbazone and AF-2 were fairly effective, semicarbazone being more effective than AF-2. Sodium nitrite was found to be totally ineffective against the cultures at all concentrations tried.
L-Asparagine auxotrophs of Saccharomyces cerevisiae: genetic and phenotypic characterization (1978)

L-Asparagine auxotrophy in Saccharomyces cerevisiae is the result of mutation in each of two unlinked cistrons, ASN1 and ASN2. Mutation in only one of these cistrons yields growth indistinguishable from that of wild-type cells under a variety of nutritional stresses. Relatively high concentrations of L-asparagine are required to permit maximal growth of the auxotrophs, and the amino acid requirement cannot be satisfied by a variety of other amino acids that serve as nitrogen sources for cell growth. Although reversion of the mutations can occur, haploid populations of cells containing only low frequencies of prototrophs can be maintained easily. In diploid cells heteroallelic for certain combinations of alleles of the two genes, mitotic recombination gives rise to prototrophic cells that accumulate to high frequency in populations of the cells.
