Orientación espacial de la atención mediante conceptos temporales

Uno de los intereses centrales de la lingüística cognitiva es el estudio de la representación mental de los conceptos abstractos tal y como lo revela el análisis de patrones de uso del lenguaje. Una teoría dominante para explicar la representación mental de los conceptos abstractos es la teoría de la “Metáfora Conceptual” (Lakoff y Johnson, 1980, 1999; Johnson, 1987). Dicha teoría sugiere que la representación mental de los conceptos abstractos tiene sus bases en dominios concretos (p.ej., el espacio). Estos dominios concretos proceden de nuestras experiencias perceptuomotoras y actúan como unidades constituyentes de los conceptos abstractos (Mandler, 1992; Johnson, 1987). Se les denomina dominios fuente y los conceptos abstractos que toman prestada estructura y contenidos de ellos se llaman dominios objetivo.
Selection and optimization of extracellular lipase production using agro-industrial waste

The aim of this study was to isolate and select lipase-producing microorganisms originated from different substrates, as well as to optimize the production of microbial lipase by submerged fermentation under different nutrient conditions. Of the 40 microorganisms isolated, 39 showed a halo around the colonies and 4 were selected ( Burkholderia, Bacillus sp., Penicillium lanosum and Corynebac glutamyl ), where strains showing lipolytic halo Radius (R) / colony radius (r) ratio greater than 2.0 were selected. The results of submerged fermentation expressed as enzymatic activity revealed that the genera of microorganisms significantly influenced the enzymatic reaction, and lipase obtained from Burkholderia cepacia was the most promising, with activity of 0.0058 U.mL -1 . It was also observed in the optimization step of lipase production that the sodium nitrate content (NaNO 3 ) had a positive effect on enzyme production, and its increase was indicative of higher enzymatic activity. The addition of sources of organic nitrogen (corn steep liquor, p = 0.2398), carbon (soybean oil, p = 0.3379), magnesium MgSO 4 . 7H 2 O (p = 0.4189) and potassium KH 2 PO 4 (p = 0.8562) had no significant effects on the lipase production and could result in decreased production of extracellular lipases. Keywords: Burkholderia cepacia, hydrolytic enzymes, residue, submerged fermentation African Journal of Biotechnology , Vol. 13(4), pp. 566-573, 22 January, 2014
Occurrence, molecular characterisation, and pathogenicity of Neoscytalidium dimidiatum on citrus in Italy

During 2008 and 2009, a new disease was noticed in eastern Sicily (Italy) in two re-grafted citrus orchards (Citrus sinensis (L.) Osbeck) on sour orange rootstock. Symptoms consisted of blight of vigorously growing shoots and a sooty canker on shoots and rootstock trunks. A Scytalidium-like fungus was isolated consistently from symptomatic tissues on 2% potato-dextrose agar (PDA). The mycelium was composed of branched, septate, brown hyphae which disarticulated into 0-1-septate phragmospores. In culture it also produced a pycnidial synanamorph, with hyaline conidiogenous cells that were intermingled with paraphyses. Conidia were ellipsoid to ovoid, hyaline, with an acutely rounded apex, truncate base, initially aseptate, becoming brown and 2-septate at maturity, with the central cell darker than the end cells. Genomic DNA was extracted from mycelia of single-conidial isolates cultivated on 2% malt extract agar and the nuclear rRNA operon spanning the 3’ end of 18S rRNA gene, the internal transcribed spacers, the 5.8S rRNA gene, and a part of the 5’ end of the 28S rRNA gene was amplified and sequenced. On the basis of morphological characters and molecular data, the fungal isolates were identified as Neoscytalidium dimidiatum (Penz.) Crous & Slippers. Koch’s postulates were satisfied and confirmed the pathogenicity of the fungus. N. dimidiatum appears to pose a serious threat to re-grafted citrus orchards.
Minimization of Leakage Current of 6T SRAM using Optimal Technology

: Leakage components are very important for estimation and reduction of leakage current, especially for low power applications. This provides the motivation to explore the design of low leakage SRAM cells. High leakage currents in deep submicron regimes are becoming a major contributor to total power dissipation of CMOS circuits as the threshold voltage, channel length and gate oxide thickness are scaled. Memory leakage suppression is critically important for the success of power-efficient designs, especially for ultra-low power applications. As the channel length of the MOSFET reduces, the leakage current in the SRAM increases. One method is to reduce the standby supply voltage (VDD) to its limit, which is the Data retention voltage (DRV), leakage power can be substantially reduced. Also, lower operating voltage will lower the stability of SRAM cell. Two schemes are employed; one in which the supply voltage is reduced and the other in which the ground potential is increased. Microwind Simulations are performed with 65nm and 120nm CMOS technology process file and the leakage currents of all the cells And analysis of read speed of 6T SRAM cell are measured and compared. Simulation results revealed that there is a significant reduction in leakage current for this proposed cell with the SVL circuit reducing the supply voltage.
Modeling the evolution of the atmospheric boundary layer coupled to the land surface for three contrasting nights in CASES-99

Abstract The modeling and prediction of the stable boundary layer over land is a persistent, problematic feature in weather, climate, and air quality topics. Here, the performance of a state-of-the-art single-column boundary layer model is evaluated with observations from the 1999 Cooperative Atmosphere–Surface Exchange Study (CASES-99) field experiment. Very high model resolution in the atmosphere and the soil is utilized to represent three different stable boundary layer archetypes, namely, a fully turbulent night, an intermittently turbulent night, and a radiative night with hardly any turbulence (all at clear skies). Each archetype represents a different class of atmospheric stability. In the current model, the atmosphere is fully coupled to a vegetation layer and the underlying soil. In addition, stability functions (local scaling) are utilized based on in situ observations. Overall it is found that the vertical structure, the surface fluxes (apart from the intermittent character) and the surface tem.
IMPLEMENTING EMERGING HIGH PERFORMANCE COMPUTING AND DATA MANAGEMENT TECHNOLOGIES IN AGENT BASED SIMULATIONS

Increasing needs for larger and more sophisticated agent based simulations of urban areas prompted the U.S. Joint Forces Command to seek out and apply technologies largely developed for academic research in the physical sciences. The use of these techniques in experimentation is closely tied to the behavioral sciences and has been shown to be effective and stable. The authors set out their decade and a half experiences in implementing high performance computing hardware, software and user interface architectures to enable heretofore unachievable results at JFCOM. They focus on three advances: the use of general purpose graphics processing units as computing accelerators, the efficiencies derived from implementing interest managed routers in distributed systems, and the benefits of effective data management given the surfeit of information produced. Their goal is to inform their simulation colleagues as to the potential improvements and the pitfalls of utilizing these technologies to meet their own challenges.
Underwater Acoustics : ICA 2016-164 Numerical Study of Unsteady Supercavitation and Flow Induced Noise Propagation

Operation of hydraulic devices and underwater vehicles is often accompanied by occurrence of flow cavitation/supercavitation. Due to the transient and unstable nature of cavitation phenomenon, it is difficult to predict the evolution of unsteady cavitation/supercavitation. The current study is focused on the numerical investigation of supercavitating liquid flow perturbed by pressure wave with one-fluid cavitation model. It is observed that the supercavity will become unstable under the impact of pressure wave and may collapse or deform locally, depending on strength of perturbation. Collapse of supercavitation results in huge pressure surge, which may cause the material erosion, noise, vibration and efficiency loss of operating devices. Understanding of unsteady supercavitation is crucial for design and optimization of such devices. Separately, the supercavity inception/development and its sustainment through ventilated cavitation may result in turbulence and fluctuations at the water-vapor interface, which are major sources of hydrodynamic noise. Here, three main sources are investigated: flow generated noise due to turbulent pressure fluctuations around the supercavity, pressure fluctuations at the vapor-water interface and pressure fluctuations due to direct impingement of ventilated gas-jets. In this study, the near and far field noise contributions from each of the aforementioned sound sources are considered via the boundary integral method. BEM based acoustic solver was developed for computing flow generated sound with flow data obtained from the CFD solver for simulating supercavitation flow.
Communications in Mathematical Physics Where Infinite Spin Particles are Localizable

Particle states transforming in one of the infinite spin representations of the Poincaré group (as classified by E. Wigner) are consistent with fundamental physical principles, but local fields generating them from the vacuum state cannot exist.While it is known that infinite spin states localized in a spacelike cone are dense in the one-particle space, we show here that the subspace of states localized in any double cone is trivial. This implies that the free field theory associated with infinite spin has no observables localized in bounded regions. In an interacting theory, if the vacuum vector is cyclic for a double cone local algebra, then the theory does not contain infinite spin representations. We also prove that if a Doplicher–Haag–Roberts representation (localized in a double cone) of a local net is covariant under a unitary representation of the Poincaré group containing infinite spin, then it has infinite statistics. These results hold under the natural assumption of the Bisognano–Wichmann property, and we give a counter-example (with continuous particle degeneracy) without this property where the conclusions fail. Our results hold true in any spacetime dimension s + 1 where infinite spin representations exist, namely s ≥ 2.
Clinical profile of amoebic liver abscess patients admitted in a tertiary care hospital

Amoebic liver abscess is an important cause of space occupying lesions of the liver, especially in tropical and sub tropical regions. It is the most frequent complication of invasive amebiasis. It may be found in all age groups but relatively rare in children. The signs and symptoms vary according to the severity of illness. The present study was done to evaluate the clinical profile of patients with amoebic liver abscess for age, gender, clinical features, site of abscess, number of abscess, treatment modality by intravenous metronidazole along with percutaneous needle aspiration and prognosis. A prospective study of 86 admitted patients of amoebic liver abscess were included in this study which was carried out in the medicine department of Khulna Medical College Hospital over a period of 2 years from July 2010 to June 2012. Mean age of patients was 45 years. Male female ratio was 7:1. The mean duration of fever was 17.9 days and the mean duration of pain was 14.1 days. The duration of fever for more than 2 weeks was seen in 38 cases. Regarding clinical features, the major symptoms of fever, pain abdomen and dysentery were seen in 81, 78 and 10 cases respectively. The major signs as determined by clinical and radio imaging studies were hepatomegaly in 76, right lobe abscess in 60, left lobe abscess in 12, multiple abscesses in both lobes in 18, ascites in 5 and right sided pleural effusion in 12 cases respectively. All the cases underwent percutaneous needle aspiration. 5 cases died out of 86 patients. Bang Med J (Khulna) 2015; 48 : 20-23
Upconverting Luminescence Imaging and Tomography for Biomedical Applications

Tissue optics is a field devoted to study the interaction of light with tissue. Over the last decades, much thanks to the field of optical spectroscopy, the knowledge of tissue optics has been steadily increasing. This has catalyzed the interest in applying tissue optics as a clinical tool. This thesis studies an area within tissue optics dealing with fluorescence molecular imaging and tomography. For most visible wavelengths, light does not penetrate more than a few millimeters into tissue. But in the diagnostic window (∼ 600 to 1600 nm), penetration up to several centimeters is possible. This opens up the possibility of imaging fluorescent contrast agents deep in tissue. Fluorescent imaging has a notable importance in biomedical applications. Shimomura, Chalfie and Tsien were recently rewarded with the Nobel prize for discovering and developing the green fluorescent protein, which has become a very important fluorescent marker. Fluorescent imaging can, for example, be used to study biological responses from drugs in small animals over a period of time, without the need to sacrifice them. Currently, considerable amounts of research are being performed to enable three-dimensional reconstructions of contrast agent distributions inside animals, so called fluorescent tomography. The area of fluorescent imaging and tomography have long been adversely affected by the ever-present endogenous tissue autofluorescence. The autofluorescence conceals the signal from the contrast agents when using Stokes-shifted fluorophores, effectively limiting the signal-tobackground sensitivity. In this thesis, it is shown that by replacing the traditional Stokes-shifted fluorophores with upconverting nanocrystals, it is possible to avoid the nuisance of autofluorescence. The nanoparticles emit light of a shorter wavelength than their excitation wavelength, effectively shifting the signal to a wavelength region where no autofluorescence is present. Experiments on tissue phantoms, with realistic optical properties, were performed, and it was shown that it is possible to detect an autofluorescence-free signal. Also a theoretical framework for using the nanocrystals for three-dimensional tomographic reconstruction was derived. Simulations were performed based on this framework, showing promising results. Based on the results presented in this thesis, we believe that upconverting nanocrystals may very well be envisaged as important biological markers for tissue imaging purposes.

Polymeric Micelles for SiRNA and AON Delivery

Immuno-nanoparticles of poly(ᴅ,ʟ-lactide-co-2-methyl-2-carboxytrimethylene carbonate)-g-poly(ethylene glycol) (poly(LA-co-TMCC)-g-PEG) have been used to target breast cancer cells through the specific binding of trastuzumab antibodies to over-expressed human epidermal growth factor receptor 2 (HER2). Small interfering RNA (siRNA) and antisense oligonucleotides (AONs) disrupt the synthesis of select proteins. It is hypothesized that oligonucleotides coupled to polymeric immuno-nanoparticles can be used for gene silencing and specifically to target luciferase. The first objective is to demonstrate the capacity to create dual functional micelles with antibodies and oligonucleotides. The second objective is in vitro testing of the nanoparticle for gene silencing activity. Oligonucleotides are conjugated to the nanoparticle by sequential click reactions of Diels Alder chemistry and copper catalyzed azide-alkyne cycloadditions, respectively. A luciferase assay is used to quantify knockdown of luciferase levels in SKOV-3luc cells (HER2+, luc+). When used in conjunction with a targeted drug delivery vehicle, the nanoparticles provide selective interactions with SKOV-3luc cells.
Preferential Market Access Design: Evidence and Lessons from African Apparel Exports to the Us and the EU

Least developed countries rely on preferential market access. Proof of sufficient transformation has to be provided to customs in importing countries by meeting Rules of Origin requirements to benefit from these preferences. These Rules of Origin have turned out to be complicated and burdensome for exporters in the least developed countries. Starting around 2001, under the United States Africa Growth Opportunity Act, 22 African countries exporting apparel to the United States can use fabric from any origin (single transformation) and still meet the criterion for preferential access (the so-called Special Rule), while the European Union continued to require yarn to be woven into fabric and then made into apparel in the same country (double transformation). This paper uses panel estimates over 1996-2004 to exploit this quasi-experimental change in the design of preferences. The paper estimates that this simplification contributed to an increase in export volume of about 168 percent for the top seven beneficiaries or approximately four times as much as the 44 percent growth effect from the initial preference access under the Africa Growth Opportunity Act without the single transformation. This change in design also mattered for diversity in apparel exports, as the number of export varieties grew more rapidly under the Africa Growth Opportunity Act special regime.

Antimony in the soil-plant system - a review

Environmental context. Soil contamination by antimony (Sb) has become an environmental problem of much concern in recent years, because increasing mining and industrial use has led to widespread soil contamination by this biologically unessential, but potentially carcinogenic element. We reviewed the available literature and found that Sb is generally taken up by terrestrial plants in proportion to the concentration of soluble Sb in soil over a concentration range covering five or more orders of magnitude, a finding that is relevant in particular for the assessment of environmental and health risks arising from Sb-contaminated soils. But very little is known about the mechanisms of Sb uptake by plants. Abstract. Soil contamination by antimony (Sb) due to human activities has considerably increased in the recent past. We reviewed the available literature on Sb uptake by plants and toxicity risks arising from soil contamination by Sb and found that Sb is generally taken up by terrestrial plants in proportion to the concentration of soluble Sb in soil over a concentration range covering five or more orders of magnitude. However, very little is known about the mechanisms of Sb uptake by plants. Also the deposition of resuspended soil particles on the surfaces of aerial plant surfaces can result in high plant Sb concentration in the vicinity of Sb-contaminated sites. Although soil pollution by Sb may be rarely so severe as to cause toxicity problems to humans or animals consuming plants or food derived from plants grown on Sb-contaminated sites, such risks may arise under worst-case conditions.
TOWARDS MORE COMMUNITY-ORIENTED AND COLLABORATIVE PLANNING FOR ALASKA NATIVE VILLAGES

Based on reviews of existing plans as well as interviews and conversations with 153 people that live in Alaska Native Villages (ANVs) or influence ANVs plans and policies, this article describes how planning for climate change adaptation and hazard mitigation takes place and provides suggestions for improvement. Planning processes are generally initiated and overseen by outside entities and have limited community participation, as they are disconnected from community events and activities. A more participatory approach that engages ANV residents by building on existing indigenous community practices may be more helpful in developing a common vision for adaptation. Planners could improve planning by spending more time talking to community members, and if desired by ANVs mentoring leadership to better engage in the process and assisting with dispute resolution. ANVs could improve planning by providing for activities that foster connectivity and a common vision and supporting efforts to build community leadership.
Leader following Speed Consensus in Induction Motors using Multi-Agent and Hybrid Controller Scheme

This paper explores a novel design of utilizing Leader following multi-agent system (MAS) consensus algorithm with Field Oriented Control (FOC), induction motors using a Hybrid control scheme containing regulation, pole placement and tracking (here after RST), controller along with model reference adaptive control (MRAC). To ensure system stability, Massachusetts institute of technology (MIT), rule is incorporated to validate that the cost function gets diminished over time. To follow the speed of leader, a leader following consensus protocol of multi-agent system is merged so that we can control the speed of induction motors. In this new approach, each motor along with its complete unit (Voltage Source Converter (VSC) and local controller) is considered as a single agent. It is proved that the consensus is reached among leader and its followers not only without delay but also with delay. The communication topology is supposed to be fixed and it is also assumed that every agent can share its information (speed data), with neighbors. The model is simulated using MATLAB and obtained results ensure the effectiveness of the design approach.
