Open Air Plasma Deposition of Superhydrophilic Titania Coatings

A method for the deposition and functionalization of a nanostructured organotitanate thin film, which imparts superhydrophilicity to a surface with a one‐step, open‐air process, is described. Extreme wetting (Θ < 5°) is achieved through synergistic contributions from both nanoscale roughness, visible light absorption caused by nonmetal dopants, and oxygen vacancies and surface activation by reactive plasma species. To test the efficacy of this material as an antifog coating, glass is coated and subjected to aggressive changes in humidity. Under both fogging and defrosting conditions, the superhydrophilic coating achieves a high degree of transparency, showing nearly two orders of magnitude improvement over the bare glass. The measured adhesion of the superhydrophilic coating is 5.9 J m−2, nearly double that of the solution‐processed control. The reliability of the coating is further validated by demonstrating scratch‐resistance. Additionally, the incorporation of organic matter into the molecular structure of the coating disrupts long‐range crystallinity from developing. This structural and subsequent chemical analysis of the coating reveals that inorganic and organic species are intimately connected at the nanoscale via alkyl and alkoxy bridges. The amorphous organotitanate material is distinct from conventional TiO2, which requires high temperature crystallization and extensive UV irradiation to display similar superhydrophilic qualities.
Analyses of Bifidobacterium, Lactobacillus, and total bacterial populations in healthy volunteers consuming calcium gluconate by denaturing gradient gel electrophoresis and real-time PCR

The objective of this study was to examine the impact of a common calcium gluconate supplement on the intestinal microbiota of healthy humans, with specific emphasis on bifidobacteria and lactobacilli. In this study, 12 healthy adults consumed 2.4 grams of calcium gluconate daily for three weeks. The fecal microbiota from weekly collected stool samples was subjected to three different analyses: community profiling by PCR-DGGE, generic profiling of Bifidobacterium and Lactobacillus by genus-specific PCR-DGGE, and quantification of these two genera by genus-specific real-time PCR. The gross PCR-DGGE profiles for each subject appeared to be unaffected by the gluconate consumption. Genus-specific PCR-DGGE profiles also showed unchanged bifidobacterial populations present in 9 of the 12 subjects throughout the study. Conversely, the lactobacilli-specific PCR-DGGE profiles did vary in most of the subjects during the study period. Real-time PCR assays showed an appreciable increase in bifidobacterial abundance (0.43 to 1.48 logs) while the gluconate supplement was consumed in 5 of the 12 subjects; however, this stimulatory effect diminished from 3 of the 5 subjects two weeks following the termination of gluconate supplementation. Lactobacilli exhibited similar trends, but to a lesser extent and for only three of the subjects. We conclude that the amount of gluconate (2.4 g/day) ingested for calcium supplementation purpose is probably not enough to confer any significant prebiotic effect for most healthy adults.
International Comparison of Sustainable Rating Tools

This paper undertakes an international comparison of global sustainability tools and examines their characteristics and differences. Most importantly, it focuses on which tools from different countries can be directly compared with each other (i.e., is a five-star building with one rating system directly comparable with a four-star rating of another rating system? ). The results are designed to provide some clarification of the assessment tools for sustainable buildings, which in turn will assist investors, developers, tenants, and government bodies in making informed decisions about green buildings. In addition, it is envisaged that removing some of the uncertainty associated with sustainable buildings will increase transparency for stakeholders and facilitate their acceptance.
Co-production of contaminated landscapes: anthropogenic loading and food web structure drive mercury bioaccumulation in abandoned gold mines

Artisanal and small-scale mining is a significant and growing livelihood across the global South, which all too often leaves a legacy of contaminated landscapes. Given the increasing reliance of economies on metals and minerals, it is critical to understand what controls contamination outcomes in this rapidly developing extractive practice. Here, we demonstrate that the emerging concept of co-production offers a novel way to elucidate the joint contributions of natural and societal factors in shaping contaminant exposure from artisanal and small-scale mining. Specifically, understanding the co-production of contaminated landscapes requires attention to both the political economy of mining, including how labor and extraction methods differ across mines, as well as the sources and pathways of mercury exposure. In Madre de Dios, Peru, we measured mercury levels in wildlife inhabiting abandoned gold mining sites worked with different extraction technologies. We found that the type of technology used, whether heavy machinery or suction-pump based, influenced mercury loading into mines, and together with differences in food-web structure, mediated mercury biomagnification rates. Mercury concentration increased 2.1 to 3.7-fold per trophic level, and bioaccumulation levels were high in both mined and unmined sites—indicating elevated background levels in the region. We also found evidence of lateral transfer of mercury from abandoned mining pits to terrestrial food webs. This observation indicates that the footprint of mercury contamination extends well beyond individual mines, affecting the larger landscape. Our findings underscore the necessity of understanding the entangled ways in which social and ecological factors contribute to the production of toxic landscapes.
Moving Beyond Automation: A Framework and Research Agenda Studying the Role of Information Systems in e-HR

Building on Zuboff’s (1985) concepts of the “automating” and “informating” effects of information technology, this study develops a framework that identifies the major areas in which information technology (IT) has the potential to transform the practice and delivery of human resource (HR) management. The framework briefly outlines how a human resource information system (HRIS) assists in the automation of HR processes and supports better information gathering and decision making by managers and HR professionals. Then, using the recruiting function of human resources, the manuscript illustrates how this framework can be used to inform HRIS research and identify gaps in the HRIS literature. This study concludes with a discussion of research questions, which, if examined, will help inform researchers as they study the use of IT to support the firms’ HR function.
Prediction of the Effectiveness of Flopper-Stopper Roll Damping Device.

Abstract : The effectiveness of a series of flopper-stopper roll damping devices on a Torpedo Weapons Retriever at zero speed in random beam seas was investigated. The ship was modeled as a one-degree-of-freedom system, and the flopper-stopper was modeled as an equivalent linear damping element based upon a detailed analysis of the forces on the device. The tension in the cable of the flopper-stopper was also estimated. The flopper-stopper was found to be an effective roll damping device. (Author)
The dynamic-thermal structures of the planetary boundary layer dominated by 
synoptic circulations and the regular effect on air pollution in Beijing

Abstract. Synoptic circulations play important roles in meteorological conditions and air quality within the planetary boundary layer (PBL). Based on Lamb-Jenkinson weather typing and multiple field measurements, this study reveals the mechanism of how the coupling effects of multiscale circulations influence PBL structure and pollution. Due to the topographic blocking in the daytime, pollutants accumulate in the plain areas horizontally. The sinking divergent flows overlying on the rising convergent flows within the PBL inhibit the continuously upward dispersion of aerosols vertically. At night, the horizontal and vertical coupling mechanisms synergistically worsen the pollution. The large-scale environmental winds and regional-scale breezes affect the pollution directly via the horizontal coupling effect, which generates a pollution convergent zone of different directional flows. The relative strength of flows causes the severely polluted area to move around horizontally from 39° N to 41° N. In addition, the multiscale circulations regulate the mixing and diffusion of pollutants indirectly via the vertical coupling effect, which changes the PBL dynamic-thermal structure. The warm advection transported by the upper environmental winds overlies the cold advection transported by the lower regional breezes, generating strong wind direction shear and advective inversion. The capping inversion and the convergent sinking motion within the PBL suppress massive pollutants below the zero speed zone. The multilayer PBL under cyclonic circulation has no diurnal variation. Weak ambient winds strengthen the mountain breezes observably at night, the temperature inversion can reach 900 m. The nocturnal shallower PBL, consistent with the zero velocity zone between ambient and mountain winds, can reach 600 m. By contrast, the PBL under southwesterly circulation is a mono-layer with obvious diurnal variation, reaching 2000 m in the daytime. The strong winds circulations restrain the development of regional breezes, the zero speed zone is located at 400 m and the inversion is lower than 200 m at night. The PBL under westerly circulation has a hybrid structure with both multiple aerosol layers and diurnal variation. The inversion is generated by the vertical shear of zonal winds. Clean and strong north winds are dominated under anticyclone circulation, the vertical shear and the diurnal variation of thermal field disappear because of strong turbulent mixing, and there is no significant PBL structure. Our results imply that the algorithm of atmospheric environmental capacity under synoptic circulations, such as the cyclonic type, with a multilayer PBL needs to be improved.
A case report of a mucormycosis caused by Lichtheimia ramosa in a patient with acute myeloid leukemia

Mucormycosis because of Lichtheimia ramosa is an unusual opportunistic fungal infection that can potentially be fatal in immunocompromised hosts. We present a fatal case of mucormycosis, affecting a 59-year-old woman with diabetes and acute myeloid leukemia. Palatal mucormycosis with sinonasal invasion was confirmed by mycological culture and histopathology. Exact species identification of Lichtheimia ramosa was performed by PCR-sequencing of ITS1-5.8S- ITS2 regions of the ribosomal genes. The patient was managed medically as surgical approach was not possible, and she unfortunately died. To our knowledge, this is the first report of Lichtheimia ramosa infection in Tunisia confirmed molecularly.

60 MeV proton irradiation effects on NO-annealed and standard-oxide deep submicron MOSFETs

The impact of 60 MeV proton irradiation on the static device parameters of CMOS transistors fabricated in a 0.18 /spl mu/m technology is reported and studied as a function of the polysilicon gate length L/sub poly/. In addition, the role of the gate dielectric in the radiation response of the threshold voltage, the transconductance, the subthreshold swing, the series resistance and the gate-induced drain leakage (GIDL) current is investigated. For certain parameters, an anomalous length dependence has been observed. Furthermore, a stronger degradation is found for the transistors with an NO-annealed gate dielectric compared with a standard thermal gate oxide. Combining the charge separation technique with the GIDL current, additional insight in the damage mechanisms is gained. It is shown that there is evidence for electron trapping close to the drain in the case of the NO devices.
Introducing ACLED: An Armed Conflict Location and Event Dataset

This article presents ACLED, an Armed Conflict Location and Event Dataset. ACLED codes the actions of rebels, governments, and militias within unstable states, specifying the exact location and date of battle events, transfers of military control, headquarter establishment, civilian violence, and rioting. In the current version, the dataset covers 50 unstable countries from 1997 through 2010. ACLED’s disaggregation of civil war and transnational violent events allow for research on local level factors and the dynamics of civil and communal conflict. Findings from subnational conflict research challenges conclusions from larger national-level studies. In a brief descriptive analysis, the authors find that, on average, conflict covers 15% of a state’s territory, but almost half of a state can be directly affected by internal wars.
Railway timetabling from an operations research

In this paper we describe Operations Research (OR) models and techniques that can be used for determining (cyclic) railway timetables. We discuss the two aspects of railway timetabling: ($i$) the determination of arrival and departure times of the trains at the stations and other relevant locations such as junctions and bridges, and ($ii$) the assignment of each train to an appropriate platform and corresponding inbound and outbound routes in every station. Moreover, we discuss robustness aspects of both subproblems.
Comparison of drag measurements of two axisymmetric scramjet models at Mach 6

Axial forces on quasi-axisymmetric scramjet models designed for operation at Mach 6 and Mach 8 were measured in the T4 Stalker tube at The University of Queensland using a single component stress wave force balance. A Mach 6 nozzle was used. The nozzle supply enthalpy was varied from 3 to 9 MJ/kg and the nozzle supply pressure from 35 to 45 MPa. As the conditions varied, the Mach number varied from 5.7 to 6.7. For both test models, the drag coefficients decreased with increasing Mach number. However, significant differences between the models were not observed over a range of free stream Mach numbers. A theoretical procedure to calculate the drag coefficient was found to give good agreement with experiments when appropriate account was taken of flow spillage at the intake.
Thermal analysis of a high-speed generator

The machine under study is a permanent magnet synchronous generator intended for operation at high speeds together with a micro-turbine in a combined heat and power (CHP) unit. Target power is 110 kW at 70000 rpm. The study is both theoretical and experimental since it includes calculation of loss distribution and thermal analysis together with calorimetric measurements of losses and temperature measurements. In this paper the thermal model is described. Using results from loss calculation and calorimetric measurements a thermal analysis is carried out. It is shown that introducing a copper screen in the rotor reduces the losses to acceptable values. A limit for the allowable rotor losses is given.
Fat reduction in chocolate: a multidisciplinary approach considering emulsion science and consumer expectations

Chocolate is consumed in large quantities, but is high in fat and calories, and has limited nutritional benefits. Producing reduced-fat chocolate offers a way of reducing energy consumed, if the consumer will accept the product. The aims of the research presented in this thesis were: i) to investigate consumer response to reduced-fat chocolate; ii) to investigate formulation routes for producing a reduced fat chocolate. Focus group data indicated ambivalence towards chocolate, with some negativity towards the concept of a reduced-fat indulgent product. By manipulating label information it was shown that whilst consumers expected to like chocolate labelled ‘reduced-fat’ less than the standard chocolate, ratings of actual liking and of sensory attributes were similar. Thus, personal experience plays a greater role than expectations. This suggests that if the sensory characteristics of a reduced-fat chocolate can be matched to a standard chocolate, actual liking should not be affected. Packaging concepts indicated how different components of the package affect liking. Water in oil cocoa butter emulsions were produced using a high shear mixer and a margarine line. Formulation changes (emulsifier type and concentration, and gelatin concentration) and processing parameters (shaft speeds and temperatures, and flow rate) were considered. All emulsions had small droplets (typically 1-5μm) and little ‘free water’. When produced on the margarine line fat crystals in polymorphic form V were produced. Crystalline shells were also observed at the droplet interface. Pilot plant experiments resulted in comparable emulsions, with small droplets and fat crystals in form V. Although a full chocolate was not produced, the potential for margarine technology to produce a reduced-fat chocolate was demonstrated.

The Application of Risk Based Inspection to Pressure Vessels and Aboveground Storage Tanks in Petroleum Fuel Refineries

Plant reliability and profitability are important performance indicators for oil refineries. The amount of inspection and maintenance resources that is devoted to process equipment effects the overall plant performance. Dedicating the same level of resources to inspecting and maintaining each piece of equipment is not cost effective and can lead to oversight of high risk equipment. Although in an operating plant, the number of high risk items usually exists in lower percentages than low risk items, an oversight in the inspection and maintenance of high risk equipment may produce catastrophic results. Risk based inspection (RBI) provides a methodology for prudent assignment of resources to assess and maintain equipment integrity based on their risk levels. The application of RBI to pressure vessels and aboveground storage tanks are demonstrated through two examples related to a crude distillation column and a crude storage tank.

High speed permanent magnet machine design with minimized stack-length under electromagnetic and mechanical constraints

Certain aircraft and military applications require high speed machines with low stack-length and the lowest possible weight. Hence, the accommodation of the highest bore diameter may seem the natural option. However, a rotor design with high diameter results in significant increase in mechanical stresses in the employed magnet retention. In a sleeved magnet retention mechanism, the sleeve thickness can be increased in order to accommodate the stresses. However, this will result is significant drop in air-gap flux-density and will not yield the high power density expected by the machine. This paper presents an analytical technique that combines the sleeve stress model and the air-gap flux density model to calculate the optimal rotor diameter to achieve the maximum power of the machine design for a minimum stack-length. The technique is applied to both a Carbon Fibre sleeve version and a metallic sleeve version. The analytical calculation of the stresses is validated with mechanical finite-element simulations. The machine design with the analytical calculations is validated with electromagnetic finite element simulations. The results confirm the rotor design strategy and the design technique.
Phase matching of high-order harmonics in hollow waveguides

We investigate the phase matching of a high-harmonic generation by intense, 20 fs laser pulses in a gas-filled capillary waveguide. We identify several regimes in which the harmonic field can build up coherently: a balance of atomic and waveguide dispersions, noncollinear Cerenkov phase matching, and a balance of atomic and plasma dispersions. The role of atomic dispersion is examined by measuring and calculating the harmonic signal for several gases. We also predict and provide preliminary evidence for a regime where phase matching occurs only at specific fractional ionization levels, where the harmonic signal is sensitive to the absolute phase of the carrier wave.
