Microbial Removal of Alkanes from Dilute Gaseous Waste Streams: Kinetics and Mass Transfer Considerations

Treatment of dilute gaseous hydrocarbon waste streams remains a current need for many industries, particularly as increasingly stringent environmental regulations and oversight force emission reduction. Biofiltration systems hold promise for providing low‐cost alternatives to more traditional, energy‐intensive treatment methods such as incineration and adsorption. Elucidation of engineering principles governing the behavior of such systems, including mass transfer limitations, will broaden their applicability. Our processes exploit a microbial consortium to treat a mixture of 0.5% n‐pentane and 0.5% isobutane in air. Since hydrocarbon gases are sparingly soluble in water, good mixing and high surface area between the gas and liquid phases are essential for biodegradation to be effective. One liquid‐continuous columnar bioreactor was operated for more than 30 months with continued degradation of n‐pentane and isobutane as sole carbon and energy sources. The maximum degradation rate observed in this gas‐recycle system was 2 g of volatile organic compounds (VOC) /(m3·h) . A trickle‐bed bioreactor was operated continuously for over 24 months to provide a higher surface area (using a structured packing) with increased rates. Degradation rates consistently achieved were approximately 50 g of VOC/(m3·h) via single pass in this gas‐continuous columnar system. Effective mass transfer coefficients comparable to literature values were also measured for this reactor; these values were substantially higher than those found in the gas‐recycle reactor. Control of biomass levels was implemented by limiting the level of available nitrogen in the recirculating aqueous media, enabling long‐term stability of reactor performance.
An Integrated Planar EMI Filter for Ultra-high Frequency Power Converters

In this paper, we propose an integrated planar electromagnetic interference (EMI) filter for ultra-high frequency power converters switching at or above 10 MHz. The integrated planar EMI filter structure consists of coreless planar spiral windings (CPSW) and parallel copper plates. The entire structure includes both the differential-mode (DM) and common-mode (CM) filters and can be fabricated in a single multilayer printed circuit board. The CPSW is firstly characterized by a lumped high-frequency circuit model which is then extended to form the equivalent circuit of the EMI filter. The performance of the differential-mode (DM) and common-mode (CM) filters is investigated individually and then they are combined to form a planar EMI filter which can handle the DM and CM noise simultaneously. Simulated and measured results are included and they confirm the filtering effectiveness of the integrated planar EMI filter.
Raisonnement à partir de cas dynamique pour la réutiliation contextuelle de l'expérience

Cet article traite du raisonnement a partir de l’experience tracee (RaPET), un paradigme de raisonnement qui exploite les traces d’interaction laissees par les utilisateurs dans des environnements numeriques. Dans le RaPET, les traces d’interaction permettent de conserver les experiences de resolution de probleme des utilisateurs « en contexte », leur reutilisation s’en trouve donc facilitee. Par ailleurs, les traces d’interaction peuvent etre utilisees comme des sources de connaissances pour decouvrir d’autres connaissances utiles au processus de raisonnement. Ce papier decrit les principes du RaPET et propose une architecture generale pour le developpement des applications a base de traces. Nous mettons en particulier l’accent sur l’articulation entre le RaPET et les systemes a base de traces (SBT) dans le contexte du developpement d’outils d’assistance aux utilisateurs. Pour cela, nous decrivons les connaissances et les modeles de connaissances impliques dans les tâches de raisonnement. Nous montrons les avantages que presente l’utilisation des traces comme des conteneurs de connaissances pour la reutilisation de l’experience. Nous discutons egalement des questions liees a l’ingenierie des connaissances dynamiques et au role du RaPET au regard de cette problematique. Enfin, nous presentons un rapide etat des lieux des travaux developpes dans ce contexte et nous proposons un plan de travail pour le RaPET, afin d’identifier « ce qu’il reste a faire ». Nous montrons egalement pourquoi le RaPET peut tirer parti de la dynamique actuelle des developpements autour des traces tout en apportant des ameliorations aux applications a base de traces.
Expansion de requêtes par apprentissage automatique dans un assistant pour la recherche d'information

ABSTRACT: Tools available to search information on the Web have a general approach, ignoring a user's characteristics, and this limits the quality of the results that they may provide. The AIRA system presented here uses document references gathered by the user to build a profile to describe him, and it uses this profile to interpret and filter the results retrieved by Web search engines. In this article, we focus on an algorithm to expand queries, using machine learning techniques, and on the problems caused by the evaluation of systems of this type. RESUME : Les outils disponibles de recherche d'information sur le Web ont une approche generaliste, ne prenant pas en compte les caracteristiques de l'utilisateur, ce qui limite la qualite des resultats qu'ils sont susceptibles de fournir. Le systeme AIRA presente ici utilise les references documentaires rassemblees par l'utilisateur pour construire un profil le representant, exploite pour interpreter et filtrer les resultats proposes par les moteurs de recherche. Dans cet article nous nous focalisons sur un algorithme d'expansion de requetes a l'aide de techniques de l'apprentissage machine, et sur les problemes par l'evaluation de cette famille de systemes.
Efficacy and Safety of 0.2% Hyaluronic Acid in the Management of Dry Eye Disease

Objectives: To evaluate the safety and efficacy of a new artificial tear containing 0.2% hyaluronic acid, as compared with 0.9% saline solution, in mild dry eye patients after 1-month use in a crossover study design with washout periods. Methods: Overall, 16 mild dry eye patients were included. After a week of washout, every patient used the experimental product (Visaid 0.2%) and the control product (0.9% saline solution), each for a month (3–8 drops daily). Both products were preservative free. The percentage change for the following variables were calculated and analyzed: Ocular Surface Disease Index (OSDI) questionnaire, visual acuity, intraocular pressure, ophthalmoscopy evaluation, biomicroscopy findings, fluorescein corneal staining and lissamine green conjunctival staining, tear breakup time, contrast sensitivity, Schirmer's test, and subject satisfaction. Results: Patients reported an improvement (a significant decrease of −19.5%±27.5%) in OSDI scores after using Visaid 0.2% and a worsening (a significant increase of 19.2%±32.4%) after using 0.9% saline solution; the difference was significant (P=0.0087, Student's t test). Significant changes (P⩽0.04, Wilcoxon's test) were found comparing Visaid 0.2% with saline solution for bulbar hyperemia (−39.1%±50.8% vs. 7.8%±12.0%, respectively), corneal staining (−26.0%±53.0% vs. 36.5%±73.3%), conjunctival staining (−54.7%±53.4% vs. −7.8%±47.2%), and subjective satisfaction (26.8%±28.5% vs. −13.3%±22.5%). There were no significant differences in the safety parameters for either solution. Conclusion: This clinical trial demonstrates the safety of Visaid 0.2% and its clear benefit over 0.9% saline solution.
MxiK and MxiN interact with the Spa47 ATPase and are required for transit of the needle components MxiH and MxiI, but not of Ipa proteins, through the type III secretion apparatus of Shigella flexneri

The type III secretion (TTS) pathway is used by numerous Gram‐negative pathogens to inject virulence factors into eukaryotic cells. The Shigella flexneri TTS apparatus (TTSA) spans the bacterial enveloppe and its assembly requires the products of approximately 20 mxi and spa genes. We present a functional analysis of the mxiK, mxiN and mxiL genes. Inactivation of mxiK and mxiN, but not mxiL, resulted in the assembly of a non‐functional TTSA that lacked the outer needle. The amounts of needle components MxiH and MxiI were drastically reduced in mxiK and mxiN mutants and in the secretion defective spa47 mutant, indicating that MxiH and MxiI are degraded if they do not transit through the TTSA. Remarkably, expression of MxiH‐His in the mxiN mutant and MxiI‐His in the mxiK mutant restored assembly of a functional TTSA, as shown by the ability of these strains to enter into epithelial cells and to secrete Ipa proteins in response to activation by Congo red. Using a two‐hybrid screen in yeast and immunoprecipitation assays from S. flexneri extracts, we identified interactions between MxiK and Spa33 and Spa47 and between MxiN and Spa33 and Spa47. These results suggest that transit of the needle components MxiH and MxiI through the TTSA involves the concerted action of the cytoplasmic proteins Spa47, Spa33, MxiK and MxiN. They also show that neither MxiK nor MxiN are absolutely required for secretion of Ipa proteins, provided that the TTSA is correctly assembled.
High-throughput manufacturing of polymer nanofibers via electrohydrodynamic jetting from planar arrays of microfabricated externally-fed emitters

We report the design, fabrication, and characterization of novel microfabricated, multiplexed sources for highthroughput production of polymer nanofibers. The devices are planar arrays of high-aspect-ratio silicon emitters with surfaces covered by an array of micropillars that enable surface tension-driven feed of liquid to the emitter tips. The sources are assembled from monolithic linear arrays of emitters etched out of a silicon wafer using deep reactiveion etching. Experimental data show high array utilization and uniform generation of nanofibers with average diameter equal to ~250 nm. Increase of the operational bias voltage results in increasing the emission current and nanofiber flux.
Research, part of a Special Feature on Systems Science for Managing Europe's Seas Past and future challenges in managing European seas

Marine environments have undergone large-scale changes in recent decades as a result of multiple anthropogenic pressures, such as overfishing, eutrophication, habitat fragmentation, etc., causing often nonlinear ecosystem responses. At the same time, management institutions lack the appropriate measures to address these abrupt transformations. We focus on existing examples from social-ecological systems of European seas that can be used to inform and advise future management. Examples from the Black Sea and the Baltic Sea on long-term ecosystem changes caused by eutrophication and fisheries, as well as changes in management institutions, illustrate nonlinear dynamics in social-ecological systems. Furthermore, we present two major future challenges, i.e., climate change and energy intensification, that could further increase the potential for nonlinear changes in the near future. Practical tools to address these challenges are presented, such as ensuring learning, flexibility, and networking in decision-making processes across sectors and scales. A combination of risk analysis with a scenario-planning approach might help to identify the risks of ecosystem changes early on and may frame societal changes to inform decision-making structures to proactively prevent drastic surprises in European seas.
Large‐scale evaluation of quantitative reproducibility and proteome coverage using acid cleavable isotope coded affinity tag mass spectrometry for proteomic profiling

Strategies employing non‐gel based methods for quantitative proteomic profiling such as isotope coded affinity tags coupled with mass spectrometry (ICAT‐MS) are gaining attention as alternatives to two‐dimensional gel electrophoresis (2‐DE). We have conducted a large‐scale investigation to determine the degree of reproducibility and depth of proteome coverage of a typical ICAT‐MS experiment by measuring protein changes in Escherichia coli treated with triclosan, an inhibitor of fatty acid biosynthesis. The entire ICAT‐MS experiment was conducted on four independent occasions where more than 24 000 peptides were quantitated using an ion‐trap mass spectrometer. Our results demonstrated that quantitatively, the technique provided good reproducibility (median coefficient of variation of ratios was 18.6%), and on average identified more than 450 unique proteins per experiment. However, the method was strongly biased to detect acidic proteins (pI < 7), under‐represented small proteins (<10 kDa) and failed to show clear superiority over 2‐DE methods in monitoring hydrophobic proteins from cell lysates.

Los motores que requieren los vehículos eléctricos deben poseer un comportamiento eficaz, eficiente y económico. El acelerado desarrollo de la electrónica de potencia y del control de velocidad con convertidores de frecuencia permite emplear sistemas de velocidad ajustable dentro de un amplio intervalo. En este trabajo, a partir de estudios realizados en la literatura especializada, fueron comparados distintos tipos de motores sincrónicos sin devanados en el rotor para estos vehículos. Las comparaciones se realizaron en base a momento y potencia, pérdidas y eficiencia, factor de potencia, costos y otros aspectos de los motores sincrónicos de imán permanente, sincrónicos de reluctancia y sincrónicos de reluctancia asistidos por imanes permanentes. Esto permitió valorar la mejor variante técnico económica. Se evidenció que el último tipo, utilizando imanes de ferrita, asegura menor costo, con altos valores absolutos y de densidad de momento y de potencia, elevada eficiencia y alto factor de potencia.
Application Study of Investment Risk Analysis of Coastal Transportation Business of Liquid Chemical Products

With the diversification of financing method, and the characters of huge investment of the coastal transportation business of liquid chemical products project, the investment costs will be uncertain. At the same time, the uncertainty of operational costs, shipping price and quantities add to the importance of the financial risk analysis to the success of the project in financial evaluation stage for the owner or in the tendering decision making stage for the contractors. In this paper, one project financial risk analysis method based on probability theory and Monte Carlo simulation technique has been put forward, and applied in the coastal transportation business of liquid chemical products project.
Supervised Topic Models for Video Activity Recognition

Topic models successfully capture latent structure useful for unsupervised analysis of bag-of-words data. Applying these models to domains such as video activity recognition requires two critical extensions: (1) incorporating supervised information (activity labels) to recover topic structure with greater discriminative power and (2) moving beyond the bag-of-words assumption to model temporal dynamics. We propose two parallel investigations to accomplish these tasks. First, we will study generic supervision techniques for topic models, exposing shortcomings in previously published generative approaches and exploring new discriminative models based on Mixtures of Experts. Second, we will apply these supervised models to video activity classification on the challenging Hollywood2 and Olympic Sports datasets, and explore extensions that capture chronological structure inherent in real-world activities.
Investigating the spatial support of signal and noise in face recognition

We develop a model for face recognition that describes the image as a sum of signal and noise components. We describe each component as a weighted combination of basis functions. In this paper we investigate the effect of the degree of localization of these basis functions: each might describe the whole image (describe global pixel covariance) or only a small part of the face (describe only local pixel covariance). We find that performance improves when he signal is treated more locally: there is independent information about identity at every position in the image. Howerver, performance decreases when noise is treated more locally: global factors such as pose and illumination conditions can only be understood by looking at a large region of the face. We demonstrate competitive results on several databases using an optimal combination of local signal and global noise models and compare to contemporary approaches.
Relevance of Adverb Distribution for the Analysis of Sentence Representation in Agrammatic Patients

In this study, it is shown that functional categories are present in agrammatic grammar. Specifically, the verb-adverb order is investigated in three agrammatic patients by means of a constituent ordering task. It is shown that when the verb is in a nonfinite form, it either precedes or follows the specifier-like adverb (both positions are correct), but when the verb is finite, the adverb always follows it (which is the only possible order). The conclusions are that (i) a functional category (namely Inflection), which is responsible for the relative order verb-adverb (of the relevant class), must exist in agrammatic grammar, and (ii) agrammatic aphasia cannot be described as a syntactic impairment involving basic sentence structure.
The Ill-Made Knight and the Stain on the Soul

Eleonore Stump’s Atonement is a masterful and historic contribution to the project of Christian soteriology. Among its many virtues is the fact that it manages to be richly novel and innovative while at the same time hewing close and doing justice to what has been most widely and traditionally affirmed about the salvific work of Christ. One of the most interesting and important novelties in the book is her treatment of what she, following Aquinas, calls the problem of the stain on the soul. Chapter 3 presents this problem and Stump’s solution to it, explains why her solution falls short, and then suggests an alternative way of addressing it.
Service Quality Assessment of Hospitals in Asian Context: An Empirical Evidence From Pakistan

Hospitals vary from one another in terms of their specialty, services offered, and resource availability. Their services are widely measured with scales that gauge patients’ perspective. Therefore, there is a need for research to develop a scale that measures hospital service quality in Asian hospitals, regardless of their nature or ownership. To address this research need, this study adapted the SERVQUAL instrument to develop a service quality measurement scale. Data were collected from inpatients and outpatients at 9 different hospitals, and the scale was developed using structural equation modeling. The developed scale was then validated by identifying service quality gaps and ranking the areas that require managerial effort. The findings indicated that all 5 dimensions of SERVQUAL are valid in Asian countries such as Pakistan, with 13 items retained. Reliability, tangibility, responsiveness, empathy, and assurance were ranked first, second, third, fourth, and fifth, respectively, in terms of the size of the quality gap. The gaps were statistically significant, with values ≤. 05; therefore, hospital administrators must focus on each of these areas. By focusing on the identified areas of improvement, health care authorities, managers, practitioners, and decision makers can bring substantial change within hospitals.

This proposed model is compact and robust as well as capable to choose data flow to or from the antennas and work as a transceiver switch. We emphasis on the library consist of cells design with HfO2. Here we present the results a cell collection that consist of the basic circuit elements requisite for the high frequency subsystems of integrated circuits as characteristic curve, contact resistances present in switches, charge densities, the potential barrier with contacts available in devices with a reason of Hafnium-dioxide.
Análisis comparativo entre un modelo generalizado para fallas en serie y los modelos tradicionales

For several years,it had been used different models for fault location and classification in both real and simulated scenarios, which give an approximation of the fault presented in one place in a network. Currently we use three different models for series faults (one line open, two lines open and three lines open). Hence, this work presents a comparative analysis between the traditional models for seriesfaults against a generalized series faults model, based in tests for one line open case. Keywords–Symmetrical components, series faults, fault models, power system.
Hyperphosphatemia and phosphate binders.

PURPOSE The pathophysiology of hyperphosphatemia associated with end-stage renal disease and treatment with phosphate binders are discussed. SUMMARY Phosphorus is an essential element necessary for the normal function of the human body, required for skeletal construction and synthesis of DNA, proteins, and adenosine triphosphate. In healthy individuals, serum phosphorus concentrations are maintained between 2.5 and 4.5 mg/dL through diet and renal excretion. In renal insufficiency, phosphorus excretion declines and hyperphosphatemia develops. The body's compensation mechanisms cause secondary hyperparathyroidism and renal osteodystrophy. Phosphate binders provide an effective means for managing serum phosphate. Commercially available phosphate binders include calcium carbonate, calcium acetate, sevelamer, lanthanum, and, rarely, aluminum hydroxide. Because of aluminum's known toxicities, aluminum-based phosphate binders have a limited place in therapy. Calcium carbonate's benefits are seen over a narrow gastric pH range, thereby limiting the drug's utility. Calcium acetate is effective over a wide pH range. Other phosphate binders, including sevelamer hydrochloride and lanthanum carbonate, have recently entered the market, but their use remains controversial. CONCLUSION If left untreated, hyperphosphatemia can result in secondary hyperparathyroidism, renal osteodystrophy, and metastatic calcification of blood vessels and soft tissue. The treatment of hyperphosphatemia in patients with chronic renal failure includes dialysis, dietary phosphorus restrictions, phosphate-binding medications, and vitamin D analogs. Selection of phosphate binders should be based on patient characteristics, including serum phosphate, serum calcium, and intact parathyroid hormone concentrations, and patient tolerability.
