Biogeochemical Controls on Diel Cycling of Stable Isotopes of Dissolved O<sub>2</sub> and Dissolved Inorganic Carbon in the Big Hole River, Montana (2005)

Rivers with high biological productivity typically show substantial increases in pH and dissolved oxygen (DO) concentration during the day and decreases at night, in response to changes in the relative rates of aquatic photosynthesis and respiration. These changes, coupled with temperature variations, may impart diel (24-h) fluctuations in the concentration of trace metals, nutrients, and other chemical species. A better understanding of diel processes in rivers is needed and will lead to improved methods of data collection for both monitoring and research purposes. Previous studies have used stable isotopes of dissolved oxygen (DO) and dissolved inorganic carbon (DIC) as tracers of geochemical and biological processes in streams, lakes, and marine systems. Although seasonal variation in 6180 of DO in rivers and lakes has been documented, no study has investigated diel changes in this parameter. Here, we demonstrate large (up to 13%o) cycles in delta18O-DO for two late summer sampling periods in the Big Hole River of southwest Montana and illustrate that these changes are correlated to variations in the DO concentration, the C-isotopic composition of DIC, and the primary productivity of the system. The magnitude of the diel cycle in delta18O-DO was greater in August versus September because of the longer photoperiod and warmer water temperatures. This study provides another biogeochemical tool for investigating the O2 and C budgets in rivers and may also be applicable to lake and groundwater systems.
A one-dimensional wave model for a pneumatic tire (2000)

A wave equation for one-dimensional waves out of plane waves of an infinite tire belt are derived. The dynamics of the belt are regarded as those of a Timoshenko beam under tension, that is, uniformly supported by the sidewall stiffness. The sidewall is modeled here as a static stiffness controlled by the internal air pressure and the geometry of the tire cross section. The fourth-order differential wave equation is solved yielding two wave numbers as a function of frequency. These describe all the wave types of the belt. Below about 100 Hz the sidewall stiffness controls the deformation and there is only motion local to the excitation. At higher frequencies waves propagate around the belt with four different controlling mechanisms, tension, bending, shear, and longitudinal stiffness. The tire is made circular by the application of the boundary conditions, which is mainly a uniform force applied on a line across the width. The input and transfer mobilities of the belt are output, showing standing wave behavior below about 500 Hz, above which there are only propagating waves and near-field waves as on an infinite belt.
Examination of oxide scales on heat resisting alloys (1969)

Twelve iron, nickel, and cobalt heat resisting alloys were cyclic furnace oxidation tested at from 1400 degrees to 2200 degrees F (1033 to 1478 K) for from 4 to 600 hours. Retained oxide scales and spall were identified using X-ray diffraction combined with X-ray fluorescence analysis. Metallography clarified scale growth sequences. After 600 hours at 2000 degrees F (1366 K), the condition most studied, the best oxidation resistance, as reflected by weight change and spall weight, was exhibited by alloys forming single oxide scales of Al2O3 or Cr2O3. For alloys that developed multioxide scales, spinel constituent composition or lattice parameter did not correlate with oxidation resistance.

Influence of cell design on processing and performance for InP based solar cells (2002)

A comparison of homojunction and ITO/InP cells grown on the same substrate material is presented. Both cell types use a base region of MOVPE p-InP, grown under the same conditions. Cells of 4 cm/sup 2/ in area of both types have been fabricated. Issues relating to the cell processing including junction formation and grid fabrication, are discussed. Although the homojunction cells currently exhibit superior performance in terms of efficiency and open circuit voltage, there exists much scope for optimization, particularly for the ITO/InP cells. Electrical characterization suggests a buried n/sup +//i/p structure for the ITO/InP cells, with i-layer thickness dependent on both processing and subsequent treatment. Post fabrication treatment of the cells is considered, in particular handling and interconnection. Ultrasonic bonding of foil interconnects appears to be a promising technique for both cell types.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Vapour phase deposition of highly crystalline self-poled piezoelectric nylon-11 (2012)

Abstract Thin films of highly crystalline short-chain nylon-11 were fabricated by means of vapour phase deposition. Nylon-11 could be thermally evaporated without much structural degradation and for the first time the piezoelectric properties of vapour phase deposited nylon-11 were characterized. It was found that the films crystallize in a polar phase with a crystalline fraction as high as 70% and even form in a self-poled state. The results show that thermal evaporation is a straightforward alternative to the common melt or solution processing as a fabrication procedure for piezoelectric nylon-11 films.

Potassium Speciation and Distribution for the K2CO3 Additive-Induced Activation/Deactivation of Olivine During Gasification of Woody Biomass (2019)

<p>The GoBiGas plant, which comprises a 32-MW<sub>th </sub>dual fluidized bed gasifier, was constructed as a demonstration unit for converting biomass to biomethane via gasification. On several occasions during the commissioning of the plant, low activity of the olivine bed generated a high content of tar in the produced gas, which was deleterious to the downstream equipment. The problem was attributed to a deficiency of ash constituents, and the solution was to control activation of the bed material through the addition of K<sub>2</sub>CO<sub>3 </sub>to the process. This enabled extended operational periods without tar-related issues. The achieved activity could be lost during interrupted operation at which time the activation procedure had to be repeated. In the present paper analysis of the bed material samples extracted upon activation and after loss of activity using Scanning Electron Microscopy coupled with Energy Dispersive X-ray spectroscopy (SEM-EDS) showed similar morphologies for the ash layers formed around the olivine particles. The observed differences mainly related to the distributions of potassium (K) across the layers. Furthermore, surface analysis showed differences in K speciation within the outer regions. K solubility tests and X-ray photoelectron spectroscopy analyses indicated that K was present as an oxide/hydroxide rather than as a silicate on the surface of the active olivine. The presented results are of major relevance for the operation of dual fluidized bed gasifiers with fuels that are potassium-lean when ash components need to be supplied as additives </p>
Anti-ulcer agent teprenone inhibits hepatitis C virus replication: potential treatment for hepatitis C (2011)

The anti-ulcer agent teprenone inhibited HCV RNA replication and enhanced statins' inhibitory action against geranylgeranylation. This newly discovered function of teprenone may improve the treatment of HCV-associated liver diseases as an adjuvant to statins.
Collagens of Normal and Cirrhotic Human Liver (1989)

The collagens of normal and end-stage alcoholic cirrhotic human liver were investigated. Mild conditions of pepsin digestion were employed to preserved the more pepsin sensitive type IV collagen molecules while increasingly more harsh conditions were used which solubilized the type I and type III hepatic collagens. The total hepatic collagen content was elevated from 1.8-2.1 in normal liver to 7.3-8.2 percent in the end-stage alcoholic liver. The graded pepsin digestion resulted in solubilization of 76-90 percent of the total hepatic collagen. The genetically distinct types of collagen were fractionated into types I, III, IV and V preparations using judicious salt precipitation from dilute acid and neutral pH solutions. The average distribution of collagen was 42.5, 39.5, 6.9 and 10.6 percent types I, III, IV and V collagen respectively in normal liver compared to 56.6, 28.0, 5.5 and 9.6 percent respectively in the end-stage alcoholic livers. An additional 0.6 and 0.5 percent in normal and end-stage cirrhotic liver respectively were located in a fraction separating out of the salt concentration required for type VI collagen. The type IV collagen of basement membrane was separated into the constituent 95Kda alpha 1(IV) and alpha 2(IV) polypeptide chains by Agarose A 5m gel filtration with subsequent (carboxymethyl) CM-cellulose chromatography. These chains were indistinguishable from similar chains of type IV collagen isolated previously from human placenta. The type V collagen alpha chains, alpha 1(V) and alpha 2(V) were purified by a combination of Diethylaminoethyl (DEAE) and CM-cellulose chromatography. The individual chains were fragmented with cyanogen bromide to yield 9 peptides from the alpha 1(V) chain and 10 peptides from the alpha 2(V) collagen chain. These were purified and analyzed for amino acid content and molecular weight. The study suggests that all collagen types were elevated in the end-stage alcoholic liver, but type I collagen was disproportionately increased over all other collagens. These results are consistent with previous studies which demonstrated an elevated type I collagen in other fibrotic conditions such as lung fibrosis and hypertrophic scar. They do not, however, agree with the suggested disproportionate elevation of type V collagen in human alcoholic liver. The reasons for this discrepancy are discussed.

Hydrophobically modified poly (acrylic acid) using calix[4]arene derivative. Ionophoric properties and extraction abilities toward alkali metal cations (2009)

Abstract p ‐ t ‐Butyl calix[4]arene diol (distal cone) (1) was grafted with poly (acrylic acid) (PAA) to obtain hydrophobically modified PAA (PAA‐C) bearing calixarene moieties. The grafting method includes the direct esterification reaction of PAA with calixarene diol 1 which was carried out in a system of tosyl chloride (TsCl), pyridine (Py), and N,N ‐dimethylformamide (DMF). The grafting yield was studied using different molar ratios of PAA to calix[4]arene diol 1, temperature, and reaction time. The chemical composition of the PAA‐C was studied by IR and 1 H NMR spectroscopy. Also, the morphology of PAA‐C was evaluated by scanning electron microscopy. The PAA‐C had different solubility and thermal properties. The extraction ability measurements of modified PAA toward alkali metal cations (Na + , K + , Cs + ) and Ag + showed a remarkable efficiency and selectivity of PAA‐C toward Na + . The main goal of this work was to design hydrophobically modified PAA with binding ability that is suitable for ion selective membranes and chemical sensor devices such as ion‐specific electrodes, semipermeable membranes, and quartz microbalances.

Lossless light projection (1997)

A new technique for energy-preserving phase-only light projection is demonstrated. The phase-only encoding is based on an extension of the Zernike phase-contrast method into the domain of full-range [0; 2pi ] phase modulation, breaking the usual small-phase-angle limitation. Controlling the spatial average value of the input-phase pattern and choosing appropriate phase retardation at the phase-contrast filter yield pure-phase-based image formation. Experimental results demonstrate close to 90% energy efficiency. Output intensity levels with magnitudes more than 3.5times that of the input intensity level were measured in the brightest regions of the projected images.
Value and Anisotropy of the Electron and Hole Mass in Pure Wurtzite InP Nanowires (2016)

The effective mass of electrons and holes in semiconductors is pivotal in determining the dynamics of carriers and their confinement energy in nanostructured materials. Surprisingly, this quantity is still unknown in wurtzite (WZ) nanowires (NWs) made of III-V compounds (e.g., GaAs, InAs, GaP, InP), where the WZ phase has no bulk counterpart. Here, we investigate the magneto-optical properties of InP WZ NWs grown by selective-area epitaxy that provides perfectly ordered NWs featuring high-crystalline quality. The combined analysis of the energy of free exciton states and impurity levels under magnetic field (B up to 29 T) allows us to disentangle the dynamics of oppositely charged carriers from the Coulomb interaction and thus to determine the values of the electron and hole effective mass. By application of B⃗ along different crystallographic directions, we also assess the dependence of the transport properties with respect to the NW growth axis (namely, the WZ ĉ axis). The effective mass of electrons along ĉ is m<sub>e</sub><sup>∥</sup> = (0.078 ± 0.002) m<sub>0</sub> (m<sub>0</sub> is the electron mass in vacuum) and perpendicular to ĉ is m<sub>e</sub><sup>⊥</sup> = (0.093 ± 0.001) m<sub>0</sub>, resulting in a 20% mass anisotropy. Holes exhibit a much larger (∼320%) and opposite mass anisotropy with their effective mass along and perpendicular to ĉ equal to m<sub>h</sub><sup>∥</sup> = (0.81 ± 0.18) m<sub>0</sub> and m<sub>h</sub><sup>⊥</sup> = (0.250 ± 0.016) m<sub>0</sub>, respectively. While no full consensus is found with current theoretical results on WZ InP, our findings show trends remarkably similar to the experimental data available in WZ bulk materials, such as InN, GaN, and ZnO.
The Distribution of an Oil, Carbohydrate, and Protein Food Source to Members of the Imported Fire Ant Colony1 (1968)

Using a dye technique, the distribution of sugar, oil, and protein food sources among the colony of Solenopsis saevissima richteri Ford was studied. The protein was primarily distributed to larvae. The sugar was distributed to the various castes more uniformly than the oil. Larvae received a greater proportion of Sugar than the other castes. Males contained a larger percentage of sugar than workers in 24 hours but had less than workers based on body weight. Some dye and sugar was found to be regurgitated by the workers when feel sugar, thus reducing the sugar available to the colony. All castes received more oil than sugar or protein. Larvae received the greatest percentage of the oil. Males received only a small maintenance amount.
Sampling and detection of Salmonella in eggs (2017)

The detection of Salmonella in the edible internal contents of eggshells provides the most incontrovertible and epidemiologically relevant evidence that laying flocks might pose a threat to consumers. Accordingly, dependable tests for Salmonella in eggs remain essential for achieving public health objectives. Research has helped explain how eggs are contaminated by Salmonella, where the pathogen is deposited and how it potentially multiplies during egg storage, and what types of assays are best able to find contaminants. However, effective utilization of egg testing results is constrained by the methodological challenges of rapidly detecting contamination, which occurs at extremely low cell numbers and prevalence.

Near Real-Time Service Monitoring Using High-Dimensional Time Series (2015)

We demonstrate a near real-time service monitoring system for detecting and diagnosing issues from high-dimensional time series data. For detection, we have implemented a learning algorithm that constructs a hierarchy of detectors from data. It is scalable, does not require labelled examples of issues for learning, runs in near real-time, and identifles a subset of counter time series as being relevant for a detected issue. For diagnosis, we provide efflcient algorithms as post-detection diagnosis aids to flnd further relevant counter time series at issue times, a SQL-like query language for writing flexible queries that apply these algorithms on the time series data, and a graphical user interface for visualizing the detection and diagnosis results. Our solution has been deployed in production as an end-to-end system for monitoring Microsoft's internal distributed data storage and computing platform consisting of tens of thousands of machines and currently analyses about 12000 counter time series.
Autonomous robotic valve turning: A hierarchical learning approach (2013)

Autonomous valve turning is an extremely challenging task for an Autonomous Underwater Vehicle (AUV). To resolve this challenge, this paper proposes a set of different computational techniques integrated in a three-layer hierarchical scheme. Each layer realizes specific subtasks to improve the persistent autonomy of the system. In the first layer, the robot acquires the motor skills of approaching and grasping the valve by kinesthetic teaching. A Reactive Fuzzy Decision Maker (RFDM) is devised in the second layer which reacts to the relative movement between the valve and the AUV, and alters the robot's movement accordingly. Apprenticeship learning method, implemented in the third layer, performs tuning of the RFDM based on expert knowledge. Although the long-term goal is to perform the valve turning task on a real AUV, as a first step the proposed approach is tested in a laboratory environment.
Bioacumulação de selênio em células de bactérias ácido lácticas: uma alternativa para a produção animal (2011)

O selênio é um micronutriente essencial a todos os seres vivos. Esse elemento, quando em baixas concen- trações, nos animais pode comprometer a capacidade imunológica, produtiva e até mesmo a capacidade reprodutiva dos mesmos. As bactérias ácidas lácticas (BAL) provenientes do trato gastrintestinal, e da mesma forma, quando presentes nos alimentos, apresentam diversos aspectos benéficos ao seu hospedeiro como: atividade antimicrobiana, controle de patógenos e contaminações microbiológicas nos alimentos, atividade antioxidante, proteção da mucosa do trato gastrintestinal, entre outros benefícios. Devido à grande necessidade mundial da produção de alimentos, estudos com o enriquecimento de BAL com selênio podem ser promissores na produção de carne no setor agropecuário e, ainda, reduzir custos com doenças e patógenos naturais existentes no cenário agroindustrial. Desta forma, a bioa- cumulação de selênio por BAL pode ser uma alternativa eficiente na melhoria e no incremento da produção animal.
