Tissue Distribution, Elimination, and Metabolism of Dietary Sodium [36Cl]Chlorate in Beef Cattle (2005)

Two steers (approximately 195 kg) were each dosed with 62.5 or 130.6 mg/kg body weight sodium [36Cl]chlorate for three consecutive days. All excreta were collected during the dosing and 8 h withdrawal periods. The apparent radiochlorine absorption was 62-68% of the total dose with the major excretory route being urine. Parent chlorate was 65-100% of the urinary radiochlorine; chloride was the only other radiochlorine species present. Similarly, residues in edible tissues were composed of chloride and chlorate with chloride being the major radiolabeled species present. Chlorate represented 28-57% of the total radioactive residues in skeletal muscle; in liver, kidney, and adipose tissues, chlorate ion represented a smaller percentage of the total residues. Chlorate residues in the low dose steer were 26 ppm in kidney, 14 ppm in skeletal muscle, 2.0 ppm in adipose tissue, and 0.7 ppm in liver. These data indicate that sodium chlorate may be a viable preharvest food safety tool for use by the cattle industry.

New insights into prediction of weak π–π complex association through proton-nuclear magnetic resonance analysis (2020)

For analysis of weak π-π complexes proton-nuclear magnetic resonance (proton-NMR) simultaneously provides information of stacking configurations and association constants [Formula: see text] However, an apparent issue for this approach is inconsistent/impossible constant estimation which often leads to unreasonable interpretation for π-π complexation. Whether or not this proton-dependent constant variation could be attributed to simple experimental uncertainties or to more sophisticated additional unspecific shielding effects (AUS effects) was addressed by means of hypothesis tests using a robust bootstrap technique in this report. Our analysis shows the significance of AUS effects on such variation in constant estimation. A following study using numeric simulation further reveals the variation patterns induced by AUS effects and concludes that the largest [Formula: see text] among the obtained [Formula: see text] estimates of a complex is considered as the best estimate of [Formula: see text] due to minimum deviation from the true value of K and the multiple [Formula: see text] estimates of a π-π complex could provide preferable inferences for complex geometries.
The phosphopantetheinyl transferase KirP activates the ACP and PCP domains of the kirromycin NRPS/PKS of Streptomyces collinus Tü 365 (2011)

The main steps in the biosynthesis of complex secondary metabolites such as the antibiotic kirromycin are catalyzed by modular polyketide synthases (PKS) and/or nonribosomal peptide synthetases (NRPS). During antibiotic assembly, the biosynthetic intermediates are attached to carrier protein domains of these megaenzymes via a phosphopantetheinyl arm. This functional group of the carrier proteins is attached post-translationally by a phosphopantetheinyl transferase (PPTase). No experimental evidence exists about how such an activation of the carrier proteins of the kirromycin PKS/NRPS is accomplished. Here we report on the characterization of the PPTase KirP, which is encoded by a gene located in the kirromycin biosynthetic gene cluster. An inactivation of the kirP gene resulted in a 90% decrease in kirromycin production, indicating a substantial role for KirP in the biosynthesis of the antibiotic. In enzymatic assays, KirP was able to activate both acyl carrier protein and petidyl carrier domains of the kirromycin PKS/NRPS. In addition to coenzyme A (CoA), which is the natural substrate of KirP, the enzyme was able to transfer acyl-phosphopantetheinyl groups to the apo forms of the carrier proteins. Thus, KirP is very flexible in terms of both CoA substrate and carrier protein specificity. Our results indicate that KirP is the main PPTases that activates the carrier proteins in kirromycin biosynthesis.
Daily Aircraft Routing and Scheduling (1997)

In this paper we consider the daily aircraft routing and scheduling problem (DARSP). It consists of determining daily schedules which maximize the anticipated profits derived from the aircraft of a heterogeneous fleet. This fleet must cover a set of operational flight legs with known departure time windows, durations and profits according to the aircraft type. We present two models for this problem: a Set Partitioning type formulation and a time constrained multicommodity network flow formulation. We describe the network structure of the subproblem when a column generation technique is applied to solve the linear relaxation of the first model and when a Dantzig-Wolfe decomposition approach is used to solve the linear relaxation of the second model. The linear relaxation of the first model provides upper bounds. Integer solutions to the overall problem are derived through branch-and-bound. By exploiting the equivalence between the two formulations, we propose various optimal branching strategies compatible with the column generation technique. Finally we report computational results obtained on data provided by two different airlines. These results show that significant profit improvement can be generated by solving the DARSP using our approach and that this can be obtained in a reasonable amount of CPU time.

Effects of a nitrification inhibitor on decentralized biological wastewater treatment (2017)

Decentralized biological wastewater treatment has the potential to help communities conserve water and energy resources by tailoring effluent water quality for reuse closer to the point of generation. Because distributed wastewater treatment plants generally have a lower buffering capacity, pollutants pose a greater threat to the microbial community, which can greatly affect the quality of effluent water. Nitrification and denitrification are essential processes of biological wastewater treatment for the conversion of nitrogen from ammonium to atmospheric N2. This project examines and quantifies the effects of a known nitrification inhibition compound to be better able to develop an early fault detection program that utilizes multivariate statistical analysis to allow a treatment plant to operate at optimal conditions.
Contemporary and Novel Hold-Down Solutions for Mass Timber Shear Walls (2022)

‘Mass timber’ engineered wood products in general, and cross-laminated timber in particular, are gaining popularity in residential, non-residential, as well as mid- and high-rise structural applications. These applications include lateral force-resisting systems, such as shear walls. The prospect of building larger and taller timber buildings creates structural design challenges; one of them being that lateral forces from wind and earthquakes are larger and create higher demands on the ‘hold-downs’ in shear wall buildings. These demands are multiple: strength to resist loads, lateral stiffness to minimize deflections and damage, as well as deformation compatibility to accommodate the desired system rocking behaviour during an earthquake. In this paper, contemporary and novel hold-down solutions for mass timber shear walls are presented and discussed, including recent research on internal-perforated steel plates fastened with self-drilling dowels, hyperelastic rubber pads with steel rods, and high-strength hold-downs with self-tapping screws.
ONTOLOGICAL MODEL FOR REPRESENTATION OF LEARNING OBJECTIVES (2005)

Learning objects have been used to provide personalized learning experiences. In particular, sequenced learning objects are recommended according to unique individual learning objectives. The opportunity for personalization by learning objectives is not fully exploited due to limited and duplicated efforts in creating learning objectives and connecting them with learning objects. Additionally, current standardization efforts do not offer sufficient support of automatic discovery of learning objects. This thesis proposes an ontological representation model of learning objective description that aims to improve the effectiveness of consistent learning objective description, sequencing rules representation, and the availability of learning objects for personalization by learning objectives. An evaluation of the model showed that it improves the discoverability of learning objects by learning objective through annotating learning objectives in the metadata of learning objects and qualitative representation of learning objectives.

Performance Analysis of Outdoor mmWave Ad Hoc Networks (2016)

Ad hoc networks provide an on-demand, infrastructure-free means to communicate between soldiers in war zones, aid workers in disaster areas, or consumers in device-to-device (D2D) applications. Unfortunately, ad hoc networks are limited by interference due to nearby transmissions. Millimeter-wave (mmWave) devices offer several potential advantages for ad hoc networks, including reduced interference due to directional antennas and building blockages, not to mention huge bandwidth channels for large data rates. This paper uses a stochastic geometry approach to characterize the one-way and two-way signal-to-interference ratio distribution of a mmWave ad hoc network with directional antennas, random blockages, and ALOHA channel access. The interference-to-noise ratio shows that a fundamental limitation of an ad hoc network, interference, may still be an issue. The performance of mmWave ad hoc networks is bounded by the transmission capacity and area spectral efficiency. The results show that mmWave networks can support much higher densities and larger spectral efficiencies, even in the presence of blockage, compared with lower frequency communication for certain link distances. Due to the increased bandwidth, the rate coverage of mmWave can be much greater than lower frequency devices.
Biochemical Characteristics of Fibrolase, a Fibrinolytic Protease from Snake Venom (1990)

Fibrolase, a fibrinolytic enzyme isolated from Agkistrodon c. contortrix (southern copperhead) venom, solubilizes fibrin primarily by rapid hydrolysis of the alpha and beta chains. Fibrolase is also an A alpha, B beta fibrinogenase. The breakdown products of fibrin and fibrinogen following incubation with fibrolase were different from those observed with plasmin. This enzyme is a metalloprotease that was inhibited by ethylenediaminetetraacetic acid. Fibrolase was inhibited by dithiothreitol, suggesting that disulfide bonds are important for catalytic activity. It was also inhibited by alpha 2-macroglobulin, but not by the soybean or lima bean trypsin inhibitors, diisopropylfluorophosphate, or p-hydroxymercuribenzoate. Unlike thrombolytic agents such as streptokinase, fibrolase does not activate plasminogen as evidenced by the use of plasmin-specific chromogenic substrate S-2251 and by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.
Adsorption of dodecyltrimethylammonium chloride (C12TMAC) to river sediment (1990)

Abstract Adsorption distribution ratios for [14C]-dodecyltrimethylammonium chloride (C12TMAC) to sediment have been measured at realistic environmental concentrations. As observed by investigators of hydrophobic organic and metal sorption, the distribution ratio was found to be inversely related to the sediment concentration. The value of the distribution ratios varied from 440 L/kg at a sediment concentration of 248,000 mg/L up to 251,000 L/kg at a sediment concentration of 230 mg/L. Data can be fit to Freundlich isotherms with slopes ≤1. Data are consistent with an ion-exchange mechanism.

Development of computational models for the purpose of conducting individual livestock and premises traceback investigations utilizing National Animal Identification System-compliant data1 (2007)

Many of the efforts surrounding the development of the National Animal Identification System have encompassed the identification of livestock production and handling premises as well as individuals or herds of animals, whereas little effort has been directed toward the ultimate goal of animal traceback within 48 h. A mock data set representative of the Colorado cattle population was created for modeling of cattle traceability. Using this data set, algorithms were developed to complete rapid and accurate traceback and traceforward of animals or premises or both. On July 19, 2005, the Colorado Department of Public Health and Environment, in conjunction with the Colorado Department of Agriculture, conducted a test exercise pertaining to homeland security. The exercise team randomly identified animal number 926,583 (of the 2 million total animals) as a potentially infected animal of interest and requested a traceback of this animal. Traceback was accomplished in 215 s, and 540 primary coresident animals were identified. However, due to animal movements, the number of coresidents (animals exposed, directly or indirectly, to the animal of interest) expanded with coresidency level (level 1 = direct contact; level 2 = direct contact with an animal that had direct contact with the animal of interest; level 3 = direct contact with an animal that had contact with an animal that had direct contact with the animal of interest, etc.) to more than 1.2 million coresidents at level 4, and more than 90% of all animals identified as a coresident at some level. In addition to the coresidency results, the premises containing the coresidents were identified and sorted by the number of coresidents. Because of animal movement, all 19,391 premises included in the data set had coresidents at some level. This exercise demonstrated the capability of the developed algorithms to complete rapid traceback and the complexity of the resulting animal traceback output.
Fundamental cryobiology of rat immature and mature oocytes: Hydraulic conductivity in the presence of Me2SO, Me2SO permeability, and their activation energies (2000)

The hydraulic conductivity in the presence of dimethyl sulfoxide Me2SO (Lp), Me2SO (P) permeability and reflection coefficient (σ) of immature (germinal vesicle; GV) and mature (metaphase II; MII) rat oocytes were determined at various temperatures. A temperature controlled micropipette perfusion technique was used to conduct experiments at five different temperatures (30, 20, 10, 4, and –3°C). Kedem and Katchalsky membrane transport theory was used to describe the cell volume kinetics. The cell volumetric changes of oocytes were calculated from the measurement of two oocyte diameters, assuming a spherical shape. The activation energies (Ea) of Lp and P were calculated using the Arrhenius equation. Activation energies of Lp for GV and MII oocytes were 34.30 Kcal/mol and 16.29 Kcal/mol, respectively; while the corresponding Eas of P were 19.87 Kcal/mol and 21.85 Kcal/mol, respectively. These permeability parameters were then used to calculate cell water loss in rat oocytes during cooling at subzero temperatures. Based on these values, the predicted optimal cooling rate required to maintain extra- and intracellular water in near equilibrium for rat GV stage oocytes was found to be between 0.05°C/min and 0.025; while for rat MII oocytes, the corresponding cooling rate was 1°C/min. These data suggest that standard cooling rates used for mouse oocytes (e.g., 0.5–1°C/min) can also be employed to cryopreserve rat MII oocytes. However, the corresponding cooling rate required to avoid damage must be significantly slower for the GV stage rat oocyte. J. Exp. Zool. 286:523–533, 2000. © 2000 Wiley-Liss, Inc.

Abstract In the lossless symmetric reciprocal four port represented by the directional coupler, it is possible to cal culate an invariant from the measured results of the s parameters. As a result, an integrated directional coupler was fabricated with high‐permittivity ceramic waveguide (DEW: dielectric E‐plane waveguide) and a coupling of 3 dB was obtained.

Analytical Prediction of Turbulent Friction Factor in Circular Pipe Under Supercritical Conditions (2012)

An analytical method was proposed for the prediction of the turbulent friction factor in a circular pipe under supercritical conditions. The friction factor equation was based on the new wall function by Van Direst transformation which is widely used in compressed flow. The law of the wall of two layers was used and integrated over the entire flow area to obtain the algebraic form of the turbulent friction factor. The new turbulent friction formula was first adjusted to Colebrook equation in isothermal flow at supercritical pressures. And then it was validated in heated supercritical flow by several existing correlations. Similar trends were found between them, which confirms the physical validity of the new frictional formula. The theoretical analysis also shows that the friction factor due to the variation of fluid property at supercritical pressures is mainly caused by the density and viscosity variation. In viscous sublayer, both the viscosity play the main role, while in turbulent sublayer, only the density do.
Anthropometric measures are not accurate predictors of fat mass in ALS (2017)

Using FM-ADP as the standard, this study suggests that BMI and BAI are not accurate measures of FM in ALS. Furthermore, longitudinal assessments indicate that changes in BMI and BAI do not consistently reflect true changes of FM in ALS.
Long-Term Activity Recognition from Wristwatch Accelerometer Data (2014)

With the development of wearable devices that have several embedded sensors, it is possible to collect data that can be analyzed in order to understand the user's needs and provide personalized services. Examples of these types of devices are smartphones, fitness-bracelets, smartwatches, just to mention a few. In the last years, several works have used these devices to recognize simple activities like running, walking, sleeping, and other physical activities. There has also been research on recognizing complex activities like cooking, sporting, and taking medication, but these generally require the installation of external sensors that may become obtrusive to the user. In this work we used acceleration data from a wristwatch in order to identify long-term activities. We compare the use of Hidden Markov Models and Conditional Random Fields for the segmentation task. We also added prior knowledge into the models regarding the duration of the activities by coding them as constraints and sequence patterns were added in the form of feature functions. We also performed subclassing in order to deal with the problem of intra-class fragmentation, which arises when the same label is applied to activities that are conceptually the same but very different from the acceleration point of view.
Properties of metalorganic chemical vapor deposited tantalum nitride thin films (2002)

Low-resistivity tantalum nitride (TaN) films have been successfully realized by low-pressure metalorganic chemical vapor deposition using a new precursor TBTDMT (terbutylimido-tris-dimethylamino tantalum). Data from transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis indicate that 600/spl deg/C as-deposited films exhibit polycrystalline structure with <200> preferred orientation. CVD TaN films have been investigated as diffusion barriers for Cu and Al interconnections.
