HYDROGENOTROPHIC DENITRIFICATION OF HIGHLY SALINE AQUACULTURE WASTEWATER USING HOLLOW FIBER MEMBRANE BIOREACTOR

Abstract A hydrogenotrophic denitrification system with a hollow fiber membrane was evaluated for treating and recycling synthetic aquaculture wastewater. Hollow fibers ensured bubble‐less diffusion of hydrogen and subsequent removal of nitrate from the first bioreactor. The second aerobic reactor was used for biomass filtration and removal of organic matter. Nitrate and organic matter expressed as dissolved organic carbon were 50 mgl−1 and 20 mgl−1, respectively, in the inlet. Acclimatization of hydrogenotrophic bacteria to 10, 20 and 30 ppt of salinity was also observed. Optimum hydraulic retention time and denitrification rate corresponding to these salinities were 3, 5 and 6 h and 366.8, 226.2 and 193.2 gm−3day −1, respectively.
The effect of Fe-coverage on the structure, morphology and magnetic properties of α-FeSi2 nanoislands

Self-assembled α-FeSi2 nanoislands were formed using solid-phase epitaxy of low (∼1.2 ML) and high (∼21 ML) Fe coverages onto vicinal Si(111) surfaces followed by thermal annealing. At a resulting low Fe-covered Si(111) surface, we observed in situ, by real-time scanning tunneling microscopy and surface electron diffraction, the entire sequence of Fe–silicide formation and transformation from the initially two-dimensional (2 × 2)-reconstructed layer at 300 °C into (2 × 2)-reconstructed nanoislands decorating the vicinal step-bunch edges in a self-ordered fashion at higher temperatures. In contrast, the silicide nanoislands at a high Fe-covered surface were noticeably larger, more three-dimensional, and randomly distributed all over the surface. Ex situ x-ray photoelectron spectroscopy and high-resolution transmission electron microscopy indicated the formation of an α-FeSi2 island phase, in an α-FeSi2{112} ∥ Si{111} orientation. Superconducting quantum interference device magnetometry showed considerable superparamagnetism, with ∼1.9 μB/Fe atom at 4 K for the low Fe-coverage, indicating stronger ferromagnetic coupling of individual magnetic moments, as compared to high Fe-coverage, where the calculated moments were only ∼0.8 μB/Fe atom. Such anomalous magnetic behavior, particularly for the low Fe-coverage case, is radically different from the non-magnetic bulk α-FeSi2 phase, and may open new pathways to high-density magnetic memory storage devices.
Evaluation of subjectively assessed nodule traits of ostrich skins as influenced by slaughter age

Ostrich skins (n = 214) were assessed by 28 participants involved in the ostrich leather production and marketing chain. The participants were from various sectors in the ostrich industry, including producers, skin graders, leather marketers, agents and process managers. Skins were evaluated during two occasions, firstly without any knowledge of slaughter age and thereafter with prior knowledge of slaughter age. Nodule acceptability and distribution for each skin were scored on a linear scale of 1 to 10. Slaughter age, as estimated by the participants during the first evaluation, was regressed on the actual age of the birds at slaughter. The derived regression indicated that actual slaughter age accounted for approximately 46% of the variation found in estimated slaughter age. Nodule acceptability scores generally increased with slaughter age. Average scores of at least moderately acceptability were found only in skins from birds slaughtered at 11 months of age and older. A corresponding trend with increase in slaughter age was found for nodule distribution scores. Between skin variance ratios were comparatively low for nodule acceptability (0.09-0.10, depending on prior knowledge of slaughter age or not) and nodule distribution (0.05-0.06). The between scorer variance ratio was generally higher, exceeding 0.35. Scores for nodule acceptability with or without prior knowledge of the age of individual skins at slaughter were essentially the same, as judged from a near unity covariance ratio between individual skins. A similar trend was observed for nodule distribution score. The need for practical methods for the objective assessment of the acceptability of nodules and ostrich leather quality was expressed.
Basics of fluid and blood transfusion therapy in paediatric surgical patients

Perioperative fluid, electrolyte and blood transfusion therapy for infants and children can be confusing due the numerous opinions, formulas and clinical applications, which can result in a picture that is not practical and is often misleading. Perioperatively, crystalloids, colloids and blood components are required to meet the ongoing losses and for maintaining cardiovascular stability to sustain adequate tissue perfusion. Recently controversies have been raised regarding historically used formulas and practices of glucose containing hypotonic maintenance crystalloid solutions for perioperative fluid therapy in children. Paediatric intraoperative transfusion therapy, particularly the approach to massive blood transfusion (blood loss ≥ one blood volume) can be quite complex because of the unique relationship between the patient's blood volume and the volume of the individual blood product transfused. A meticulous fluid, electrolyte and blood transfusion management is required in paediatric patients perioperatively because of an extremely limited margin for error. This article reviews the basic concepts in perioperative fluid and blood transfusion therapy for paediatric patients, along with recent recommendations. For this review, Pubmed, Ovid MEDLINE, HINARI and Google scholar were searched without date restrictions. Search terms included the following in various combinations: Perioperative, fluid therapy, paediatrics, blood transfusion, electrolyte disturbances and guidelines. Only articles with English translation were used.
RF front end requirements for 3G and beyond

The cellular mobile terminals continue to evolve at a rapid pace from voice phones to Multi-band, Multi standard Multi-media devices of the future. The RF front end, of these devices continues to be more complex requiring many RF bands and Wireless standards to be supported in a single device. In addition, to support higher data rates multiple antennas and passive filters are required. Concurrency with other wireless standards puts additional constraints on passive filters, which are required to reduce the interference handling requirements of the RF transceiver. Innovation is needed in the components required in the RF front end such that the form factor, RF performance and power consumption is maintained to less complicated devices of the past, as more band and modes are added. This paper will discuss the key radio requirements of the RF front end in wireless devices.
OXIDATIVE STATUS AND THE INCIDENCE OF FATTY LIVER HEMORRHAGIC SYNDROME IN LAYING HENS FED FLAX SEEDS

The current trial was performed to investigate the influence of flax seeds on the oxidative status and incidence of FLHS in laying hens. Fifty (Hisex) bird, 20 week old, were obtained from Animal Production Research Center (kuku), were divided into two groups (n=25) for each one. The control group (A) was under control diet based on corn, maintains the (NRC, 1994) requirements for laying hens, the experimental group, supplemented by 10% flax seeds added to the diet. The trial lasted for eight weeks, blood samples were collected once per month (week 4 and 8), in EDTA coated vials, immediately placed into iced-container, centrifuged at 3000 rpm/20 min, samples were separated in aliquot, and stored at -20oC and -80oC until analysis. No incidence of fatty liver hemorrhagic syndrome was noticed after feeding laying hens diet containing 10% flax seeds for two months. Plasma analysis for enzymatic and non-enzymatic antioxidants, revealed no significant different levels of uric acid, malondialdehyde (MDA), vitamin C, and vitamin E between the control group and the treated one, while catalase (CAT), superoxide dismutase (SOD), and vitamin A, levels were significantly enhanced by the addition of 10% flax seeds. Index Terms FLHS, liver enzymes, Oxidative status, Flax seeds, Layers, SOD, CAT, MDA.
Symptoms, Vascular Risk Factors and Blood-Brain Barrier Function in Relation to CT White-Matter Changes in Dementia

The aim was to study the frequently found white-matter changes on computerized tomography (CT) in patients with dementia and to relate these changes to clinical regional brain symptomatology, vascular factors, albumin ratio [indicator of blood-brain barrier (BBB) function] and other CT changes. The study included 85 patients, average age 71 ± 8, with Alzheimer’s disease (n = 56) and vascular dementia (n = 29), who underwent CT (Siemens Somatome DR 1) of the brain. They were inpatients in a psychiatric department specialized in dementia investigations. The degree of CT white-matter changes (absence, mild-moderate, severe) was the basis for the division of the patients into three groups. As the patients without white-matter changes were significantly younger than those with such changes, all statistical analyses were controlled for age. Subcortical symptomatology was significantly more frequent in the group with severe white-matter changes, whereas the reverse was true for parietal symptomatology. Diabetes mellitus, hypertension, ischemic cardiac disease and lacunas were significantly more common in patients with white-matter changes, whereas the freqeuncy of transient ischemic attack/stroke episodes did not differ significantly between the groups. The albumin ratio was significantly higher in the groups with white-matter changes and highest in the group with severe white-matter changes. The findings indicate that white-matter changes in demented patients are at least partially an age- and stroke-independent disease manifestation of the vascular system and is associated with a specific symptom pattern. BBB dysfunction may be the link between the vasculature and the tissue damage.
Expressive speech synthesis in MARY TTS using audiobook data and emotionML

This paper describes a framework for synthesis of expressive speech based on MARY TTS and Emotion Markup Language (EmotionML). We describe the creation of expressive unit selection and HMM-based voices using audiobook data labelled according to voice styles. Audiobook data is labelled/split according to voice styles by principal component analysis (PCA) of acoustic features extracted from segmented sentences. We introduce the implementation of EmotionML in MARY TTS and explain how it is used to represent and control expressivity in terms of discrete emotions or emotion dimensions. Preliminary results on perception of different voice styles are presented.
Estimation of the abundance of an uncultured soil bacterial strain by a competitive quantitative PCR method

Strain EA25 was identified in a clone library of bacterial 16S rRNA gene sequences that had been amplified from DNA extracted from soil collected in eastern Washington State. EA25 was subsequently shown to be related to members of the genera Planctomyces and Chlamydia and most closely related (93% similarity) to strain MC18, a strain identified in an Australian soil sample (W. Liesack and E. Stackebrandt, J. Bacteriol. 174:5072-5078, 1992). A competitive quantitative PCR method developed by Zachar et al. (V. Zachar, R.A. Thomas, and A.S. Goustin, Nucleic Acids Res. 21:2017-2018, 1993) was used to estimate the abundance of this uncultured strain in soil. An estimation of the abundance of EA25 was based on the number of copies of the sequence in the DNA extracted and the efficiency of the DNA extraction. In addition, amplification rates of Escherichia coli DNAs added to soil were shown to be similar to those of DNAs from laboratory cultures of E. coli. The number of EA25 16S rRNA genes was estimated to be 2.17 x 10(8) copies per g of soil, suggesting that strains similar to EA25 and the similar Australian strain could be widely distributed and present in significant numbers in soils from temperate regions. This represents the first enumeration of 16S rDNA copies from an uncultured strain in soil.
Status and Structure of Two Populations of the Bluehead Sucker (Catostomus discobolus) in the Weber River, Utah

Abstract We compared two populations of the bluehead sucker (Catostomus discobolus) during 2007–2009 in the Weber River, Davis, Summit, and Weber counties, Utah. We estimated 225 and 546 individuals in these populations. Based on recaptured, PIT-tagged fish, annual survival of adults (202–575 mm total length) was high (77%); however, our top model indicated mortality increased with size (i.e., senescence). We documented movements ≤15 km downstream and 5 km upstream and 88% of detections from a stationary antenna occurred at night. Despite high rates of survival of adults, recruitment appeared minimal in one of the populations because it was composed primarily of mature adults. Recruitment potentially was limited by interactions with a high density of brown trout (Salmo trutta) and combined effects of an altered hydrograph (magnitude, duration, and timing) and thermal regime. If conservation of these populations is a priority, recruitment must be increased immediately in one of the populations to avoid extinction. Resumen Se compararon dos poblaciones del matalote cabeza azul (Catostomus discobolus) durante 2007–2009 en el río Weber, en los condados de Davis, Summit, y Weber, Utah. Se estimaron 225 y 546 individuos en estas poblaciones. Basándose en los peces recapturados con transmisores PIT, la supervivencia anual de adultos (202–575 mm longitud total) fue alta (77%); sin embargo, nuestro mejor modelo indicó que la mortandad aumentó con el tamaño (por ejemplo, la senectud). Documentamos desplazamientos ≤15 km río abajo y 5 km río arriba y 88% de los registros de una antena fija ocurrieron en la noche. A pesar de las altas tasas de supervivencia de adultos, el reclutamiento fue mínimo en una de las poblaciones, ya que se compuso principalmente de adultos maduros. El reclutamiento fue limitado potencialmente por la interacción con una densidad alta de trucha marrón, (Salmo trutta) y los efectos combinados de un hidrógrafo alterado (magnitud, duración, y estacionalidad) y el régimen térmico. Si la conservación de estas poblaciones es una prioridad, el éxito del reclutamiento se debe aumentar inmediatamente en una de las poblaciones para evitar extinción.
Self-tuned output scaling factor of fuzzy logic speed control of induction motor drive

The rapid advancements in induction motor drives has led to the development of robust non-linear controller such as Fuzzy Logic Controller (FLC). The proportional integral or derivative controllers (PI, PID, and PD) have been in use for induction motor drives for past decades as speed and current controller's. However, these controllers are fixed to motor parameter changes which results in decrease in performance. FLC is robust and non-linear controller which has the ability to withstand with the motor parameters variation. The conventional fuzzy speed controller depends on the speed error and the fixed scaling gains adjusted in most designs. However, this paper proposed a new self-tuned mechanism of the output scaling factor of the fuzzy speed controller which can enhance the performance of the speed and torque of the motor especially during load and parameters variation. Matlab/Simulink environment was utilized to build and design the proposed system and verify the results.
Strategically Concealing Information in the Autobiographical Implicit Association Test Combating Automatic Autobiographical Associations : The Effect of Instruction and Training in

One of the most heavily debated questions in implicit social cognition is the extent to which implicit measures can be voluntarily controlled. The experiment reported here is the first to employ a novel strategy for intentionally controlling performance in the autobiographical Implicit Association Test (aIAT). Specifically, when explicitly instructed to do so, participants were able to speed up their responses in the incongruent blocks of the aIAT and thus influence the outcome of the test. This effect was larger when the experimental instruction was followed by practice in speeding responses than when the instruction was given alone. A process-dissociation analysis suggested that the effect was due to reductions in the ability of participants’ automatic associations to influence responses when instructions to speed up were provided. This experiment provides new insight into the potential for strategic control in the performance of implicit measures and into the interplay between automatic and controlled processes underlying performance on implicit measures.
A finite difference scheme for a system of two conservation laws with artificial viscosity

In this paper we analyze an implicit finite difference scheme for the mixed initial-value Dirichlet problem for a system of two conservation laws with artificial viscosity. The system we consider is a model for isentropic flow in one space dimension. First, we show that, under certain conditions on the mesh, the scheme is stable in the sense that it possesses an invariant set (defined by the so-called Riemann invariants). We obtain this result as an extension of the same stability theorem for the LaxFriedrichs scheme in the inviscid case. Second, we show that the approximants remain bounded and, in fact, decay to the boundary values as t oo. Finally, we obtain two O(Ax2) error bounds; the first grows exponentially in time while the second, which requires that the data have small oscillation, is independent of time.
Heterozygous Disruption of the TATA-Binding Protein Gene in DT40 Cells Causes Reduced cdc25B Phosphatase Expression and Delayed Mitosis

ABSTRACT TATA-binding protein (TBP) is a key general transcription factor required for transcription by all three nuclear RNA polymerases. Although it has been intensively analyzed in vitro and inSaccharomyces cerevisiae, in vivo studies of vertebrate TBP have been limited. We applied gene-targeting techniques using chicken DT40 cells to generate heterozygous cells with one copy of theTBP gene disrupted. Such TBP-heterozygous (TBP-Het) cells showed unexpected phenotypic abnormalities, resembling those of cells with delayed mitosis: a significantly lower growth rate, larger size, more G2/-M- than G1-phase cells, and a high proportion of sub-G1, presumably apoptotic, cells. Further evidence for delayed mitosis in TBP-Het cells was provided by the differential effects of several cell cycle-arresting drugs. To determine the cause of these defects, we first examined the status of cdc2 kinase, which regulates the G2/M transition, and unexpectedly observed more hyperphosphorylated, inactive cdc2 in TBP-Het cells. Providing an explanation for this, mRNA and protein levels of cdc25B, the trigger cdc2 phosphatase, were significantly and specifically reduced. These properties were all due to decreased TBP levels, as they could be rescued by expression of exogeneous TBP, including, in most but not all cases, a mutant form lacking the species-specific N-terminal domain. Our results indicate that small changes in TBP concentration can have profound effects on cell growth in vertebrate cells.
Cognitive Performance and Grey Matter Density in Psychosis: Functional Relevance of a Structural Endophenotype

Background: Structural brain changes and cognitive impairments have been identified as indicators of genetic risk for schizophrenia. However, the pattern of associations between such structural and functional liability markers has been less well investigated. Methods: Magnetic resonance imaging data and cognitive assessments were acquired in 31 patients with psychosis, 32 non-psychotic first-degree relatives and 28 controls. The relationship between cerebral grey matter density and cognitive performance was examined using computational morphometry. Results: Two out of 6 cognitive tests revealed significant associations with grey matter density in regions of the frontal lobe, basal ganglia, thalamus and cerebellum in patients and relatives. In patients, poorer executive functioning was associated with cerebellar grey matter density deficits. In relatives, poorer executive functioning was associated with increased grey matter density in the cerebellum and frontal lobe. In both patients and relatives, strategic retrieval from semantic memory was positively associated with grey matter density in basal ganglia structures. Some additional negative associations in the patients differentiated this group from relatives. Conclusions: The overlap in structure-function relationships in individuals with schizophrenia and those with liability for the disorder may suggest that regional grey matter density alterations functionally alter particular neurocircuits, which could lead to cognitive deficits. The non-overlapping structure-function correlations may reflect disease-related or compensatory mechanisms.
SWOT analysis of the Mi Compu.MX ICT skills simulator

The use and development of simulators in education has been improved with the constant evolution of technology, specifically the computer, which has enabled the creation of more complex simulations in virtual environments. Given the importance of digital skills in the current context, simulate an environment in which implement these skills is a key step in reducing the digital divide between teachers and students. This paper presents a SWOT analysis of an ICT skills simulator developed as part of the project called “Diagnosis of laptop computers integration in teaching practices in the State of Sonora” whose main objective included conducting an assessment of the integration of laptop computers in pedagogical practices of teachers in primary education the State of Sonora (Mexico). As a result of the analysis, a proposal for improvement of the simulator is presented through a business process diagram that follows the Model and Notation Business Process.
A Distributed Framework for Monocular Visual SLAM

In Distributed Simultaneous Localization and Mapping (SLAM), multiple agents generate a global map of the environment while each performing its local SLAM operation. One of the main challenges is to identify overlapping maps, especially when agents do not know their relative starting positions. In this paper we are introducing a distributed framework which uses an appearance based method to identify map overlaps. Our framework generates a global semi-dense map using multiple monocular visual SLAM agents, each localizing itself in this map.
GEN05-3: Mobile Location Analysis Using WLAN Measurements

The purpose of the mobile location analysis is to study the mobile location accuracy, reliability, and robustness of the RF fingerprinting solution by means of the indoor WLAN signal strength measurements. First, we have compared two measurement sets collected on different days in the same building. The results of the location error are very similar which implies that these two measurements are almost time-invariance in the sense of received average power. Second, we only need make a few random measurement points in the building for the fingerprinting solution. Lastly, we examined the location error resulting from our RF fingerprinting analysis by varying the number of access points in the building.
The Piketty Transition

We study the effects on inequality of a “Piketty transition” to zero growth. In a model with a worker-capitalist dichotomy, we show first that the relationship between inequality (measured as a ratio of incomes for the two types) and growth is complicated; zero growth can raise or lower inequality, depending on parameters. Extending our model to include idiosyncratic wage risk we show that growth has quantitatively negligible effects on inequality, and the effect is negative. Finally, following Piketty’s thought experiment, we study how the transition might occur without declining returns; here, we find inequality decreases substantially if financial innovation acts to reduce idiosyncratic return risk, and does not change much at all if it acts to increase capital’s share of income.
