description: We present first results from a LOFAR census of non-recycled pulsars. The census includes almost all such pulsars known (194 sources) at declinations ${\rm Dec}> 8^\circ$ and Galactic latitudes $|{\rm Gb}| > 3^\circ$, regardless of their expected flux densities and scattering times. Each pulsar was observed for $\geq 20$ minutes in the contiguous frequency range of 110--188 MHz. Full-Stokes data were recorded. We present the dispersion measures, flux densities, and calibrated total intensity profiles for the 158 pulsars detected in the sample. The median uncertainty in census dispersion measures ($1.5 \times 10^{-3}$ pc cm$^{-3}$) is ten times smaller, on average, than in the ATNF pulsar catalogue. We combined census flux densities with those in the literature and fitted the resulting broadband spectra with single or broken power-law functions. For 48 census pulsars such fits are being published for the first time. Typically, the choice between single and broken power-laws, as well as the location of the spectral break, were highly influenced by the spectral coverage of the available flux density measurements. In particular, the inclusion of measurements below 100 MHz appears essential for investigating the low-frequency turnover in the spectra for most of the census pulsars. For several pulsars, we compared the spectral indices from different works and found the typical spread of values to be within 0.5--1.5, suggesting a prevailing underestimation of spectral index errors in the literature. The census observations yielded some unexpected individual source results, as we describe in the paper. Lastly, we will provide this unique sample of wide-band, low-frequency pulse profiles via the European Pulsar Network Database.

description: The diffusion properties of self-propelled particles which move at constant speed and, in addition, reverse their direction of motion repeatedly are investigated. The internal dynamics of particles triggering these reversal processes is modeled by a stochastic clock. The velocity correlation function as well as the mean squared displacement is investigated and, furthermore, a general expression for the diffusion coefficient for self-propelled particles with directional reversal is derived. Our analysis reveals the existence of an optimal, finite rotational noise amplitude which maximizes the diffusion coefficient. We comment on the relevance of these results with regard to microbiological systems and suggest further experiments in this context.

EVALUATION OF EXPOSURE TO ACETAMIPRID IN PESTICIDE APPLICATORS
Creators: name: Salsbury, Mark
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Acetamiprid is one of the newest and most frequently applied insecticides in agricultural settings due to low mammalian toxicity and effectiveness in strains of insects that have developed resistance to traditional insecticides. Pesticide workers who mix, handle, and apply acetamiprid-containing pesticides typically receive the largest dose through the dermal exposure route. Reliable and sensitive methods are needed to evaluate dermal exposure to acetamiprid in pesticide workers. This study was conducted to develop and apply a tape-strip method to quantitatively measure dermal exposure to acetamiprid. In addition, we explored the suitability of using either specific-gravity or creatinine normalized urine acetamiprid concentration as a biomarker of dermal exposure. Five part-time pesticide applicators were monitored using tape-strip sampling of the skin and collecting pre- and post-exposure urine samples during a spray application of acetamiprid-containing pesticide in Honduras. A liquid-chromatography tandem-mass-spectrometry method was used to quantify acetamiprid in tape-strip and urine samples (limit of quantitation for tape 10 fmol/μL and for urine sample 67 fmol/μL). Acetamiprid was detected in all tape-strip samples, with the greatest exposures measured on the arms (mean left arm 37.0 μg, mean right arm 37.4 μg) followed by the left hand (mean 27.7 μg). The estimated dermal dose was calculated for each applicator based on the tape-strip measurements and the area of skin exposed during pesticide application. A positive correlation (R^2=0.66, P=0.097) was observed between the estimated dermal dose and specific-gravity normalized acetamiprid concentrations in urine. Specific-gravity normalization of spot urine samples appears to be more suitable than creatinine normalization in biomarker studies of exposure to acetamiprid . The results of this study indicate that tape-stripping provides a suitable method to evaluate dermal exposure to acetamiprid-containing pesticides. Further studies with larger sample sizes are warranted to ascertain the relationship between dermal exposure and specific-gravity or creatinine normalized acetamiprid levels in urine.

description: Nowadays, several models of unidimensional fluid jets exploit discrete element methods. In some cases, as for models aiming at describing the electrospinning nanofabrication process of polymer fibers, discrete element methods suffer a non constant resolution of the jet representation. We develop a dynamic mesh-refinement method for the numerical study of the electro-hydrodynamic behavior of charged jets using discrete element methods. To this purpose, we import ideas and techniques from the string method originally developed in the framework of free-energy landscape simulations. The mesh-refined discrete element method is demonstrated for the case of electrospinning applications.

An Evaluation of the 37mm Cassette for Sampling an Airborne Particulate Dust
Creators: name: Wood, Mark Wendell
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1989

description: The use of the 37 mm cassette for sampling total dust in industrial hygiene is well established. This method is used to make full shift and short-term exposure measurements. Environmental levels of ranitidine hydrochloride are typically in the ug/m^3 range. This necessitates taking short-term samples at flows markedly higher than the usual flow of 2 LPM. The results of these measures should be comparable. If not, then a bias exists in the method of collection in this flow range. An evaluation of the cassette to sample airborne ranitidine was completed by comparing paired samples with respect to concentration obtained and particle size sampled. Pairs were run at 2 and 4 liters per minute. No significant difference in concentration was found in pairs taken in the Fette and dispensing areas. The particle size distributions sampled at 2 and 4 liters per minute were very similar. Thus, no bias was detected in the sampling method between 2 and 4 LPM. Full shift and short-term measures are comparable. Analysis of the cassette indicates that significant quantities of ranitidine are depositing on the wall. In the Fette room more ranitidine deposited at low flow than at high flow. This indicates a possible residence time phenomenon is responsible. Data from the dispensing area indicates wall deposition is equal between 2 and 4 LPM. Possible explanations include sedimentation, impaction and electrostatic effects.

The novelty in the algorithm is that it stops when a guaranteed upper bound for the maximum speed is reached with a prescribed accuracy. The convergence rate of the algorithm is cubic and the bound is guaranteed for gasses with the co-volume equation of state and the heat capacity ratio $γ$ in the range $(1,5/3]$

A Method for Predicting Release of Contaminants at the Point of Dredging
Creators: name: Yoon, Jeyong
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1990

description: The potential release of pollutants during the dredging process has in recent years come under the scrutiny of federal and state agencies. A simple laboratory test and mathematical model were sought to predict the concentration of contaminants released at the point of a dredging process. This research investigates the effect of initial suspended solids (SS) concentration, mixing time, and settling time in a 4-L graduate cylinder on the final water column concentrations of SS, PCBs, and selected metals (Cu, Pb, and Cd). The objective was to determine the conditions that could best simulate the actual contaminant concentrations measured in a pilot dredging operation of New Bedford Harbor. Results indicate that most of the PCBs found in the column after settling were sorbed onto suspended particles rather than dissolved. Aeration time had little effect on final SS or PCB concentration. Settling time had the most influence of the test parameters on SS and PCBs but beyond 1 hour, the effect was minimal. Analysis of settling rate indicated that flocculent rather than discrete settling occurred. From a matrix of laboratory testing using initial SS, aeration time, and settling time as variables, a non-linear regression model was used to predict final SS concentrations (from which PCBs released is calculated). Also the soluble PCB concentration was predicted by a simple equilibrium partitioning model. Particle size distributions (PSD) analyses were analyzed (Coulter Counter) on solids remaining in the laboratory column for various combinations of experimental conditions. PCB and SS concentrations obtained in New Bedford Harbor from the ports of the dredgehead and from the plume were compared to those found in the laboratory test. In general, the field and laboratory data were within one order of magnitude. However, the scatter in field data was considerable and this must be included in any analysis of predictive capability of a simple laboratory test and mathematical model. Finally, if sorbed PCB concentrations, initial suspended solids, and settling time are measured, then the total, particulate, and soluble PCBs in the water column can be predicted without elutriate tests by using the simple equilibrium partitioning model and the non-linear regression model developed to determine final SS.

description: We apply effective field theory methods to compute bino-nucleon scattering, in the case where tree-level interactions are suppressed and the leading contribution is at loop order via heavy flavor squarks or sleptons. We find that leading log corrections to fixed-order calculations can increase the bino mass reach of direct detection experiments by a factor of two in some models. These effects are particularly large for the bino-sbottom coannihilation region, where bino dark matter as heavy as 5-10 TeV may be detected by near future experiments. For the case of stop- and selectron-loop mediated scattering, an experiment reaching the neutrino background will probe thermal binos as heavy as 500 and 300 GeV, respectively. We present three key examples that illustrate in detail the framework for determining weak scale coefficients, and for mapping onto a low energy theory at hadronic scales, through a sequence of effective theories and renormalization group evolution. For the case of a squark degenerate with the bino, we extend the framework to include a squark degree of freedom at low energies using heavy particle effective theory, thus accounting for large logarithms through a "heavy-light current." Benchmark predictions for scattering cross sections are evaluated, including complete leading order matching onto quark and gluon operators, and a systematic treatment of perturbative and hadronic uncertainties.

Year: 2023

description: Im Rahmen der vorliegenden Arbeit wurden Methoden zur Berechnung der Schwingfestigkeit hoch- und höchstfester Stähle sowie randschichtverfestigter Bauteile entwickelt. Basierend auf umfangreichen experimentellen Untersuchungen verschiedener Werkstoffe wurden Methoden der FKM-Richtlinie Nichtlinear angepasst, um das zyklische Werkstoffverhalten von hoch- und höchstfesten Stählen auf Basis quasistatischer Werkstoffkennwerte abzuschätzen. Hierbei wurden Berechnungsverfahren erweitert, die die zyklische Spannungs-Dehnungs-Kurve, die Mittelspannungsempfindlichkeit sowie Schädigungsparameterwöhlerlinien auf Basis der Zugfestigkeit bestimmen können. Des Weiteren wurden Berechnungsverfahren erarbeitet, um einen Ermüdungsfestigkeitsnachweis auf Basis des Örtlichen Konzepts für randschichtverfestigte Bauteile zu ermöglichen. Da bei randschichtverfestigten Bauteilen das Versagen aufgrund der inhomogenen Materialeigenschaften und der vorliegenden Eigenspannungen sowohl vom Kerbgrund als auch vom Übergangsbereich zwischen niedrigfestem Kernmaterial und hochfester Randschicht ausgehen kann, wurden Anpassungen am in der FKM-Richtlinie Nichtlinear enthaltenen Ermüdungsfestigkeitsnachweises vorgenommen. Hierbei wurden die Algorithmen des Örtlichen Konzepts um einen sogenannten Zweipunkt-Nachweis und die Erfassung von Eigenspannungen erweitert. Dazu wurde ebenfalls ein Näherungsverfahren zur Abschätzung der elastisch-plastischen Beanspruchungen an beiden Nachweispunkten entwickelt.

description: Accurate measurements of the cross-plane thermal conductivity Λ_cross of a high-thermal-conductivity thin film on a low-thermal-conductivity (Λ_s) substrate (e.g., Λ_cross/Λ_s>20) are challenging, due to the low thermal resistance of the thin film compared to that of the substrate. In principle, Λ_cross could be measured by time-domain thermoreflectance (TDTR), using a high modulation frequency f_h and a large laser spot size. However, with one TDTR measurement at f_h, the uncertainty of the TDTR measurement is usually high due to low sensitivity of TDTR signals to Λ_cross and high sensitivity to the thickness h_Al of Al transducer deposited on the sample for TDTR measurements. We observe that in most TDTR measurements, the sensitivity to h_Al only depends weakly on the modulation frequency f. Thus, we performed an additional TDTR measurement at a low modulation frequency f_0, such that the sensitivity to h_Al is comparable but the sensitivity to Λcross is near zero. We then analyze the ratio of the TDTR signals at f_h to that at f_0, and thus significantly improve the accuracy of our Λcross measurements. As a demonstration of the dual-frequency approach, we measured the cross-plane thermal conductivity of a 400-nm-thick nickel-iron alloy film and a 3-μm-thick Cu film, both with an accuracy of ~10%. The dual-frequency TDTR approach is useful for future studies of thin films.

Effects of Instillation of Residual Oil Fly Ash on Cardiac, Pulmonary, and Thermoregulatory Parameters in Spontaneously Hypertensive Rats
Creators: name: Wichers, Lindsay Beth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: Epidemiological studies have reported a robust correlation between levels of ambient particulate matter (PM) and the incidence of morbidity and mortality, particularly among persons with cardiopulmonary disease. While similar effects have been demonstrated in animals, the mechanism(s) by which these effects are mediated are unresolved. To further investigate this phenomenon, the effects of ROFA (a model emission PM) were examined in Spontaneously Hypertensive (SH) rats (a susceptible disease model). Rats were surgically implanted with radiotelemeters capable of monitoring electrocardiogram (ECG), heart rate (HR), systemic blood pressure (BP), and core temperature (Tco). Animals were divided into 4 groups and received one of four doses of ROFA suspended in saline vehicle (0.0, 0.83, 3.33, 8.33mg/kg) through intratracheal instillation (IT). Telemetered rats were monitored continuously for 8 days post-IT and ventilatory function was examined for 6 hours/day on post-IT days 1-7. At 24 hours, 96 hours, and 192 hours post-IT, bronchoalveolar lavage fluid (BALF) was collected and examined for biochemical indices of pulmonary injury and inflammation. IT exposures to mid and high dose ROFA induced substantial decreases in HR (30-120bpm), BP (20-30mmHg), and Tco(1.2-2.6°C). The decreases in BP and HR did not return to pre-IT values until 48 and 72 hours after dosing, respectively. ECG abnormalities (rhythm disturbances, bundle branch block) were observed primarily in the high dose group. Additionally, immediate dose-related changes in ventilatory function were noted after ROFA IT, consisting of decreases in tidal volume (10-42%) and increases in frequency (52-103%), minute ventilation (12-25%), and enhanced pause(42-98%). These effects were resolved by 7 days post-IT, although BALE constituents remained elevated through Day 7 for mid and high dose ROFA groups when compared to saline vehicle. This study demonstrates substantial deficits in cardiopulmonary function in SH rats after IT exposure to ROFA PM, along with significant increases in BALF indices of pulmonary injury. Toxicity appears to be greater than that reported previously in healthy rats and comparable to that observed in other compromised rodent models.

Political economy and social change

description: For 17 years starting in 1973, Chile was ruled by a military dictatorship under Augusto Pinochet— after 143 years of almost uninterrupted liberal democracy. In 1981, a large-scale reform of the social sectors—including health, education, and pensions—was prepared by the so-called “Chicago Boys”—following Milton Friedman’s neoliberal teachings.1 The financial and administrative reforms for education included competition, decentralization, and privatization, transferring public education to municipalities, and introducing a voucher system so that private subsidized schools and municipal schools could compete.2 Catholic schools and private charities had received state subsidies through vouchers, “Subvenciones educacionales,” at least since the beginning of the 20th Century.3 They were intended not to cover the full costs of provision, but to complement private donations. The voucher system was revamped to provide the same per student subsidy to municipal and private subsidized schools. For the transfers of schools to the municipalities, a new legal entity was created to administer a school and named “Sostenedor,” which might be a municipality or a private individual owning one or more schools. This entity diversified state provision, and increased competition as teachers lost their civil servant status and the Ministry was no longer obliged to pay their salaries. Each municipality was responsible for hiring and firing teachers and for determining their salaries. Since the return to democracy in 1990, Chile has built a consensus on the objective of educational quality and pursued it systematically, if incrementally. The Concertación, a center-left coalition of parties, privileged education and health, opposed by a right wing and its agenda favoring lower taxes and direct cash transfers to the poor. The key problem at the time was the lack of resources. Along with an increase in resources and programs, the technical capacities in the Ministry of Education gradually improved, thanks to faster economic growth. Key turning points in educational budget, 1994–96 and 2008–09, were associated with technical arguments advanced by the Ministry of Education that made economic sense to the Ministry of Finance. The center- left “Concertación” coalition won four consecutive presidential elections before losing to the right-wing coalition in 2010.

description: We uncover the fine structure of a silicon vacancy in isotopically purified silicon carbide (4H-$^{28}$SiC) and find extra terms in the spin Hamiltonian, originated from the trigonal pyramidal symmetry of this spin-3/2 color center. These terms give rise to additional spin transitions, which are otherwise forbidden, and lead to a level anticrossing in an external magnetic field. We observe a sharp variation of the photoluminescence intensity in the vicinity of this level anticrossing, which can be used for a purely all-optical sensing of the magnetic field. We achieve dc magnetic field sensitivity of 87 nT Hz$^{-1/2}$ within a volume of $3 \times 10^{-7}$ mm$^{3}$ at room temperature and demonstrate that this contactless method is robust at high temperatures up to at least 500 K. As our approach does not require application of radiofrequency fields, it is scalable to much larger volumes. For an optimized light-trapping waveguide of 3 mm$^{3}$ the projection noise limit is below 100 fT Hz$^{-1/2}$.

description: Parents and peers are two reference groups that are particularly salient and important for the type of risk attitudes that are learned and adopted as one’s one (i.e., internalized) throughout adolescence. However, less is known about the extent to which adolescents differentially integrate the perceived risk attitudes of their parents vs. peers into constructing their own risk attitudes over time. Given ongoing functional changes that occur in social and motivational brain systems during adolescence (Crone & Dahl, 2012), it is important to understand how age-related changes in brain systems associated with social influence may constrain the extent to which the brain encodes and integrates the perceived risk attitudes of others in the development of risk attitudes across adolescence. The proposed study has two goals: (1) Examine age-related changes in the extent to which adolescents internalize the perceived risk attitudes of their parents vs. peers when constructing their own risk attitudes; and (2) Examine whether trajectories of adolescents’ risk attitudes are shaped by the extent to which the adolescent brain differentially utilizes internalized perceptions of their parents’ or peers’ risk attitudes over time, with a focus on brain systems implicated in social decision making (vmPFC, mPFC, dmPFC, dACC).
An Analysis of Density Enhanced Remediation of DNAPLs
Creators: name: Bond, Rick G.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2000

description: The contamination of groundwater by dense non-aqueous phase liquids (DNAPLs) poses one of the most pervasive and difficult groundwater remediation problems in the field of environmental engineering. A new concept, density enhanced remediation of DNAPL(DERD), has been proposed by Dr. Cass T. Miller that relies upon mobilization of a DNAPL while controlling its vertical migration. This report presents a conceptual model for the implementation of DERD and an analysis of the effects of selected decision variables on DERD process efficiency. Computer simulations were performed that modeled 1) injection of a dense brine into the subsurface to form a barrier against vertical DNAPL migration, and 2) subsequent extraction of the injected brine through production well(s). Dimensionless parameters formed from decision variables and hydrogeological characteristics were used to analyze simulation results, and an objective function, based on capital and recovery costs for the brine, was calculated for each simulation to rank decision variable strategies. The computer code used for this study (HST3D, developed by the U.S. Geological Survey) employs finite difference methods to solve three-dimensional groundwater flow, heat, and solute transport in a saturated porous medium. Analysis of the results revealed an optimal range of production and injection rates for each specified well spacing configuration that minimized the unit cost objective function. In addition, the objective function was minimized by injection to production rate ratios near 1.0 and by use of variable pumping rates for both the injection and production wells. Brine recovery efficiency was improved by extraction through multiple wells rather than the central well alone. High permeability and low permeability homogeneous medium simulations resulted in similar unit costs and quantities of brine, but the timescales required to complete the process were significantly longer for low permeability soil. Segmentation of the simulation domain into strata with different soil permeability resulted in less efficient brine injection and higher brine unit costs.

description: As a potential building block for the next generation of devices or multifunctional materials that are spreading almost every technology sector, one-dimensional (1D) carbon nanomaterial has received intensive research interests. Recently, a new ultra-thin diamond nanothread (DNT) has joined this palette, which is a 1D structure with poly-benzene sections connected by Stone-Wales (SW) transformation defects. Using large-scale molecular dynamics simulations, we found that this sp3 bonded DNT can transit from a brittle to a ductile characteristic by varying the length of the poly-benzene sections, suggesting that DNT possesses entirely different mechanical responses than other 1D carbon allotropies. Analogously, the SW defects behave like a grain boundary that interrupts the consistency of the poly-benzene sections. For a DNT with a fixed length, the yield strength fluctuates in the vicinity of a certain value and is independent of the "grain size". On the other hand, both yield strength and yield strain show a clear dependence on the total length of DNT, which is due to the fact that the failure of the DNT is dominated by the SW defects. Its highly tunable ductility together with its ultra-light density and high Young's modulus makes diamond nanothread ideal for creation of extremely strong three-dimensional nano-architectures.

description: On the basis of the Froggatt-Nielsen mechanism, we study quark flavor mixings in the $SU(6) \times SU(2)_R$ model. The characteristic structure of the CKM matrix is attributed to the hierarchical effective Yukawa couplings due to the Froggatt-Nielsen mechanism and also to the state-mixings beyond the MSSM. We elucidate the detailed form of the CKM matrix elements and find interesting relations between the \textit{CP} violating phase and three mixing angles. Taking the existing data of three mixing angles, we estimate the quark \textit{CP}-phase at $δ= (75 \pm 3)^{\circ}$. This result is in accord with observations.

The Influence of Environmental Tobacco Smoke on the Lifetime Probability of Lung Cancer Due to Exposure to Radon
Creators: name: Cheng, Kuo-His
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: An analysis concerning the effect of environmental tobacco smoke (ETS) on estimation of lifetime risk of radon-induced lung cancer is made. Based on the consideration of radon dosimetry as a function of age, a generalized state-vector model is used to estimate the total probability of lung cancer due to exposure to both radon and ETS during a normal (73 year) lifespan. This report suggests that there is a general tendency of increasing working level concentration of radon progeny and decreasing unattached fraction of radon progeny RaA (Po-218) with greater amounts of ETS present in the home. The initial concentration of ambient aerosols plays an important role in quantifying the effect of ETS on radon exposure. The combined ETS and radon exposure may either raise or lower the risk of lung cancer associated with radon exposure alone, primarily depending upon the initial aerosol concentration and amounts of cigarette smoke.

description: An intrinsic time in Geometrodynamics is obtained with using a scaled Dirac's mapping. By addition of a background metric, one can construct a scalar field. It is suitable to play a role of intrinsic time. Cauchy problem was successfully solved in conformal variables because they are physical ones. First, the intrinsic time as a logarithm of determinant of spatial metric, was applied to a cosmological problem by Misner. A global time is exist under condition of constant mean curvature slicing of spacetime. The volume of hypersurface and so-called mean York's time are canonical conjugated pair. So, the volume is the intrinsic global time by its sense. The experimentally observed redshift in cosmology is the evidence of its existence.
