Los nuevos sistemas de informacion en la gestion universitaria. El caso de la Universidad del Pais Vasco/Euskal Herriko Unibertsitatea (UPV/EHU)
Venue: Revista Internacional de Economia y Gestion de las Organizaciones

De la misma forma que el sistema de educacion superior espanol viene evolucionando, impulsado por el proceso de homogeneizacion de las titulaciones en los distintos estados europeos, proceso que conduce tambien hacia la armonizacion de la metodologias docentes, los sistemas de in formacion y de gestion de las universidades se han ido adaptando, igualmente, a las nuevas necesidades de la comunidad universitaria y del resto de sus stakeholders. De forma muy especial, los gestores universitarios demandan una informacion mas acorde a los cambios estrategicos y organizativos ac tualmente en marcha, en especial tras la puesta en marcha de los nuevos planes de estudio y la obli gatoriedad de contar con un Sistema de Garantia Interna de Calidad. Se presentan en este trabajo tanto las herramientas de informacion y gestion de la calidad tradicionalmente utilizadas como algunas de las que se estan implantando en la actualidad en la UPV/EHU, y en particular en sus centros universi tarios y titulaciones, orientadas todas ellas a que los responsables universitarios puedan disponer de informacion mas relevante para su toma de decisiones.
An Experimental and Numerical Study on the Aerothermal Characteristics of a Ribbed Transonic Squealer Tip Turbine Blade With Purge Flow

Detailed heat transfer coefficient (HTC) and film cooling effectiveness (Eta) distribution on a squealer tipped first stage rotor blade were measured using an infrared (IR) technique. The blade tip design, obtained from a Solar Turbines Inc. gas turbine, consisted of double purge hole exits and four ribs within the squealer cavity, with a bleeder exit port on the pressure side close to the trailing edge. The tests were carried out in a transient linear transonic wind tunnel facility under land based engine representative Mach/Reynolds number. Measurements were taken at an inlet turbulent intensity of Tu =12% with exit Mach numbers of 0.85 (Reexit=9.75x10 5 and 1.0 (Reexit 1.15x10 6 with the Reynolds number based on the blade axial chord and the cascade exit velocity. The tip clearance was fixed at 1% (based on engine blade span) with a purge flow blowing ratio BR 1.0. At each test condition, an accompanying numerical study was performed using Reynolds Averaged Navier Stokes (RANS) equations solver ANSYS Fluent to further understand the tip flow characteristics. The results showed that the tip purge flow has a blocking effect on the leakage flow path. Furthermore, the ribs significantly altered the flow (and consequently heat transfer) characteristics within the squealer tip cavity resulting in a significant reduction in film cooling effectiveness. This was attributed to increased coolant leakage flow mixing due to increased recirculation within the squealer cavity. Overall, the peak heat transfer coefficient on the cavity floor increased with exit Mach/Reynolds number. NOMENCLATURE BR Averaged blowing Ratio (BR rcUc /r U,avg
Observed variability in the upper layers at the Equator, 90degE in the Indian Ocean during 2001 2008, 2: meridional currents
Venue: Climate Dynamics

In the Indian Ocean, the observed variability of meridional currents (MC) at the Equator, 90degE shows distinct 10 20 day (quasi biweekly) north south reversals in the near surface 40 350 m water column. Unlike the zonal currents, the seasonal variability in the MC field is strikingly absent in the annual cycle over this water column. However, the strong amplitude oscillations penetrate deep during boreal winter, boreal spring and boreal fall seasons. There is also a suggestion that they are weak and shallow during summer monsoon season during the years when the intraseasonal zonal westerly wind bursts along the equator are weak or absent. These quasi biweekly oscillations are attributed to the westward propagating equatorially trapped mixed Rossby gravity (MRG) or Yanai waves triggered by the westward propagating meridional wind (MW) field along the equator suggesting a possibility of wind forced response of the upper ocean. A careful examination reveals interannual modulation of this quasi biweekly variability in the MC field. The salinity induced vertical stratification observed in the near surface layer through barrier layer effects also shows a significant influence on the MC field on 10 20 day time scale. The upwelling and downwelling cycles caused in the near off equatorial region as a result of the westward propagation of the MRG waves are noticed in the pycnocline inferred from the vertical temperature and salinity profiles recorded by a nearby TRITON CTD mooring deployed at 1.5degS, 90degE. The observed sharp differences in the MCs between years appear to be determined by the strengths of both MWs and barrier layer thickness. A suggestion of westward propagation of quasi biweekly variability in SST along the equator with phase speed resembling that of the MRG waves is also episodically seen during most years.
The Sawqirah contourite drift system in the Arabian Sea (NW Indian Ocean) A case study of interactions between margin reactivation and contouritic processes

The relationships between oceanic circulation in the Arabian Sea and Late Cenozoic climate changes, including variations in monsoon intensity at the million year time scale, remain poorly investigated. Using multibeam and seismic data, we provide the first description of a contourite drift in the Arabian Sea, along the south eastern Oman margin. This contourite drift is referred as the "Sawqirah Contourite Drift System" Late Miocene reactivation of the south eastern Oman margin resulted in the formation of a complex anticline system, which shaped the seafloor topography above which the Sawqirah Drift subsequently developed. The drift resulted from the circulation of bottom currents within the North Intermediate Indian Water. Major seismic unconformities identified within the Sawqirah Drift were tied to Ocean Drilling Program (ODP) drill holes, and allowed defining distinct episodes of drift construction. At least two of these unconformities record reorganizations of the oceanic circulation at 4.5 4.8 Ma and 2.4 Ma. The 4.5 4.8 Ma old unconformity is coeval with the onset of upwelling of deep and cold waters in the Owen Basin. The 2.4 Ma old unconformity records a major episode of Indian monsoon intensification (at the million year time scale) over the Arabian Sea, indicating strong coupling between oceanic and atmospheric circulation processes.
DLSAS: Distributed Large Scale Anti Spam Framework for Decentralized Online Social Networks
Venue: 2016 IEEE 2nd International Conference on Collaboration and Internet Computing (CIC)

In the last decade, researchers and the open source community have proposed various Decentralized Online Social Networks (DOSNs) that remove dependency on centralized online social network providers to preserve user privacy. However, transitioning from centralized to decentralized environment creates various new set of problems, such as adversarial manipulations. In this paper, we present DLSAS, a novel unsupervised and decentralized anti spam framework for DOSNs. DLSAS provides decentralized spam detection that is resilient to adversarial attacks. DLSAS typifies massively parallel frameworks and exploits fully decentralized learning and cooperative approaches. Furthermore, DLSAS provides a novel defense mechanism for DOSNs to prevent malicious nodes participating in the system by creating a validation overlay to asses the credibility of the exchanged information among the participating nodes and exclude the misbehaving nodes from the system. Extensive experiments using Twitter datasets confirm not only the DLSAS's capability to detect spam with higher accuracy compared to state of the art approaches, but also the DLSAS's robustness against different adversarial attacks.
Structural engineering of three dimensional phononic crystals

are attracting the research interest of a growing community of scientists for the possibility to develop novel materials with advantageous properties that arise from the ability to tailor the propagation of elastic waves, and thus energy, through them. In this work, we propose a three dimensional phononic crystal whose unit cell has been engineered to obtain a strong wave attenuation band in the middle of the acoustic frequency range. The combination of its acoustic properties with the dimensions of the unit cell and its static mechanical properties makes it an interesting material for possibly several applications in civil and mechanical engineering, for instance as the core of an acoustically insulating sandwich panel. A sample of this crystal has been manufactured and experimentally tested with respect to its acoustic transmissibility. The performance of the phononic crystal core is remarkable both in terms of amplitude reduction in the transmissibility and width of the attenuation band. A parametric study has been finally conducted on selected geometrical parameters of the unit cell and on their effect on the macroscopic properties of the crystal. This work represents an application oriented example of how the macroscopic properties of an artificially structured material can be designed, according to specific needs, by a conventional engineering of its unit cell.

From Dietary Fiber to Host Physiology: Short Chain Fatty Acids as Key Bacterial Metabolites
Venue: Cell

A compelling set of links between the composition of the gut microbiota, the host diet, and host physiology has emerged. Do these links reflect cause and effect relationships, and what might be their mechanistic basis? A growing body of work implicates microbially produced metabolites as crucial executors of diet based microbial influence on the host. Here, we will review data supporting the diverse functional roles carried out by a major class of bacterial metabolites, the short chain fatty acids (SCFAs) SCFAs can directly activate G coupled receptors, inhibit histone deacetylases, and serve as energy substrates. They thus affect various physiological processes and may contribute to health and disease.
The roles of bile acids and sphingosine 1 phosphate signaling in the hepatobiliary diseases
Venue: Journal of Lipid Research

Based on research carried out over the last decade, it has become increasingly evident that bile acids act not only as detergents, but also as important signaling molecules that exert various biological effects via activation of specific nuclear receptors and cell signaling pathways. Bile acids also regulate the expression of numerous genes encoding enzymes and proteins involved in the synthesis and metabolism of bile acids, glucose, fatty acids, and lipoproteins, as well as energy metabolism. Receptors activated by bile acids include, farnesoid X receptor a, pregnane X receptor, vitamin D receptor, and G protein coupled receptors, TGR5, muscarinic receptor 2, and sphingosine 1 phosphate receptor (S1PR)2. The ligand of S1PR2, sphingosine 1 phosphate (S1P) is a bioactive lipid mediator that regulates various physiological and pathophysiological cellular processes. We have recently reported that conjugated bile acids, via S1PR2, activate and upregulate nuclear sphingosine kinase 2, increase nuclear S1P, and induce genes encoding enzymes and transporters involved in lipid and sterol metabolism in the liver. Here, we discuss the role of bile acids and S1P signaling in the regulation of hepatic lipid metabolism and in hepatobiliary diseases.
Pelvic Floor Muscle Training: Underutilization in the USA
Venue: Current Urology Reports

Pelvic floor disorders are highly prevalent in women of all ages and can greatly impair quality of life. Pelvic floor muscle training (PFMT) is a viable treatment option for several pelvic floor conditions including urinary incontinence and pelvic organ prolapse. PFMT is a program of therapy initiated by an experienced clinician (e.g. women's health or urology nurse practitioner (NP) physical therapist (PT) that involves exercises for women with stress urinary incontinence (UI) and exercises combined with behavioral or conservative treatments (lifestyle changes, bladder training with urge suppression) for women with urgency or mixed UI. These exercise programs are more comprehensive than simple Kegel exercises. Despite evidence based research indicating the efficacy and cost effectiveness for treatment of urinary incontinence, PFMT is not commonly used as a first line treatment in clinical practice in the USA (Abrams et al. 2012) This article will review PFMT for the treatment of UI and pelvic organ prolapse (POP) and theorize how this conservative therapy can be utilized more effectively in the USA.
On the island biogeography of aliens: a global analysis of the richness of plant and bird species on oceanic islands

To characterize the relationship(s) between species richness and area for alien plant and bird species on islands, and to identify commonalities and differences in those relationships for these different taxa, and between alien and native species; (2) to test whether area per se, native species richness or human factors related to area is the primary determinant of alien species richness; and (3) to explore the effects on alien island biogeography of isolation, productivity and the time since first European landfall. Location Islands around the world.  We used structural equation models (SEMs; supported by generalized linear models) to interrogate data on the alien and native species richness of birds and plants on islands.  Alien plant and bird species richness were both strongly correlated with island area, with similar slopes on logarithmic axes. SEMs for both plants and birds revealed positive direct effects of native species richness and human population size, and positive indirect effects of area, on alien species richness. The models also identified indirect effects of temperature (positive) and isolation (negative) on alien species richness. Native plant and bird species richness were both predicted by direct effects of area (positive) temperature (positive) and isolation (negative) However, native plant richness was the only direct predictor of native bird species richness, and the strongest direct predictor of alien bird species richness, for islands with both plant and bird richness data.  Our analyses recover the species area, species isolation and productivity relationships in native richness. Alien species richness was most strongly related to native species richness, with additional effects of human population size. Human population size most likely determines the number of alien species that arrive on an island, while the effect of native species richness may be driven by the influence of habitat heterogeneity on the likelihood that those populations persist (establishment success)
Politics and Promises: A Multimodal Social Semiotic Interpretation of Political Party Emblems and Slogans as Discourse of Hope in a Democratic Nigeria

Working within the framework of multimodal discourse analysis (MDA) and critical metaphor analysis (CMA) this study examines the emblems and slogans of the four main political parties in Nigeria: the People's Democratic Party (PDP) the All Progressives Congress (APC) the All Progressives Grand Alliance (APGA) and the Labour Party (LP) which have become instruments of campaign and propaganda. While the emblems/logos are visual (iconic) representations of party ideology, the slogans are verbal rhetorical affirmations of what the emblems represent. Based on insights from the theory of multimodality, this study is an attempt to use a social semiotic approach in the interpretation of visual communication. Multimodality understands visual as representation and communication. The Kress and van Leeuwen (2006) approach which this study adopts tries to interpret how the multiple modes in multimodal communication yield themselves to different levels of meaning realization.
A Comparison of E Assessment Assignment Submission Processes in Introductory Computing Courses

Students completing university education programs are generally required to complete an Introductory Computing Course (ICC) in their first year of study. Introductory Computing, also referred to as Computer Fundamentals or End User Computing, are theoretical and practical in nature. Due to the large number of students completing the ICCs, institutions are introducing and increasingly utilising e learning systems and e assessment systems. Research generally focuses on e assessment from an educator or instructor's perspective. In this study, the students' perceptions of e assessment were evaluated, exploring different options with regards to the submission and assessment of MS Office documents as part of the ICC. The study identified the best method of submission from a students' perspective considering various factors and comparing three different submission methods. The results highlighted suggestions for improving the on line submission system. The results could assist educators and instructors utilising e assessment systems in improving the submission and marking processes, in any course where files are required for submission.
Diagnosis of invasive fungal infections in haematological patients by combined use of galactomannan, 1,3 b D glucan, Aspergillus PCR, multifungal DNA microarray, and Aspergillus azole resistance PCRs in blood and bronchoalveolar lavage samples: results of a prospective multicentre study.
Venue: Clinical microbiology and infection the official publication of the European Society of Clinical Microbiology and Infectious Diseases

High mortality rates of invasive fungal disease (IFD) especially invasive aspergillosis (IA) in immunocompromised haematological patients and current diagnostic limitations require improvement of detection of fungal pathogens by defining the optimal use of biomarkers and clinical samples. Concurrent bronchoalveolar lavage (BAL) and peripheral blood samples of 99 haematological patients with suspected IFD were investigated within a multicentre prospective study. Diagnostic performance of a galactomannan (GM) enzyme immune assay (EIA) a 1,3 b D glucan assay (BDG) an Aspergillus PCR, and a multifungal DNA microarray (Chip) alone or in combination were calculated. IFD were classified as proven (n=3) probable (n=34) possible (n=33) and no IFD (n=29) according to EORTC/MSG criteria. GM, PCR, and Chip showed superior diagnostic performance in BAL than in blood, whereas specificity of BDG in BAL was poor (48% (14/29) The combination of GM (BAL) with BDG (blood) showed sensitivity, specificity, positive predictive value (PPV) negative predictive value (NPV) and DOR (diagnostic odds ratio) of 92% (34/37) 93% (27/29) 94% 90% and 153.0, respectively. Combining GM (BAL) with PCR (BAL) showed convincing diagnostic potential for diagnosing IA with sensitivity, specificity, PPV, NPV, and DOR of 85% (17/20) 97% (28/29) 94% 90% and 158.7. Addition of the DNA microarray resulted in further detection of two mucormycetes infections. In 1 out of 15 Aspergillus DNA positive samples a triazole resistance mediating Cyp51A mutation was found. Combination of biomarkers is superior to their sole use in diagnosing IFD, particularly IA. Integrating blood and BAL samples into a diagnostic algorithm is an advantageous approach.
Characterization of the genes involved in nitrogen cycling in wastewater treatment plants using DNA microarray and most probable number PCR
Venue: Frontiers of Environmental Science Engineering

AbstractTo improve nitrogen removal performance of wastewater treatment plants (WWTPs) it is essential to understand the behavior of nitrogen cycling communities, which comprise various microorganisms. This study characterized the quantity and diversity of nitrogen cycling genes in various processes of municipal WWTPs by employing two molecular based methods:most probable number polymerase chain reaction (MPN PCR) and DNA microarray. MPN PCR analysis revealed that gene quantities were not statistically different among processes, suggesting that conventional activated sludge processes (CAS) are similar to nitrogen removal processes in their ability to retain an adequate population of nitrogen cycling microorganisms. Furthermore, most processes in the WWTPs that were researched shared a pattern:the nirS and the bacterial amoA genes were more abundant than the nirK and archaeal amoA genes, respectively. DNA microarray analysis revealed that several kinds of nitrification and denitrification genes were detected in both CAS and anaerobic oxic processes (AO) whereas limited genes were detected in nitrogen removal processes. Results of this study suggest that CAS maintains a diverse community of nitrogen cycling microorganisms; moreover, the microbial communities in nitrogen removal processes may be specific.
