Pteroptyx curticolle Pic 1923: 59. Pteroptyx curticollis Pic. McDermott 1966: 117. Ballantyne & McLean 1970: 265. Type. Unknown sex, fragmentary appearing to consist of prothorax, margins of elytra and possibly ventral piece of tho- rax. TONKIN Lac-Thô. Labelled 1. Red type printed; 2. Handwritten ‘Lac Tho Larkin’; 3. Pteroptyx curticolle n. sp. ’ (MNHN).
Remarks. Ballantyne and McLean (1970) indicated at the time of writing the fragmentary nature of the type. The specimen photographed by Yiu (pers. comm.) appears to have been reassembled as the fragments of the elytra have their ventral surface uppermost while the pronotum is dorsal side uppermost. Pic distinguished Pt. curticollis from Pt. atripennis by the form of the prothorax. There are no distinguishing features in his description which would enable any assumption of sex of this specimen, but it can possibly be assumed to be the same colour as Pt. curticollis (orange pronotum and dark brown elytra).

description: Blueberry mosaic disease was first described in the 1950s but the causal agent has not been characterized to date. Next generation sequencing was employed in the identification of the causal agent and an undescribed ophiovirus, tentatively named Blueberry mosaic associated virus (BlMaV), was detected in diseased plants. The segmented genome of the virus is comprised of three negative-sense RNAs (RNAs 1-3) encoding four proteins. The population structure of the virus was studied in detail using 59 isolates collected from various blueberry growing regions of North America and Slovenia. The open reading frames of RNAs 2 and 3 were analyzed; revealing stringent purification selection for both proteins. The information acquired will provide valuable data for the development of reliable assays able to detect the widest arrays of BlMaV isolates.

A comparision study of migratory raptor distribution and habitat use at the Cape May peninsula stopover
Creators: name: Frank, Cristina A.
Publisher: name: No Publisher Supplied
Year: 2007

description: Stopover habitats must provide sufficient resources for migratory birds to rest and refuel before negotiating ecological barriers and continuing migration.  The pressure of finding suitable habitat intensifies when migrants encounter stopovers that have been degraded by human activities.  There is limited documentation of how migrants respond to altered landscapes. This comparison study evaluated potential relationships between changes in habitat use and distribution of migratory raptors and changes in the landscape at Cape May Peninsula, New Jersey by replicating point count surveys originally conducted in the late 1980s.  This valuable coastal stopover provides resources for fall migrants as they prepare to cross the 18km-wide Delaware Bay. Habitat loss and degradation has occurred throughout the Cape May Peninsula with the greatest losses occurring in the lower 10km. Migratory raptors concentrated near their crossing point in the lower 10km in all survey years, however in 2002, there was a significant decline in the number of raptors observed in this region of the peninsula.  Raptors were more evenly distributed throughout northern regions of the study area suggesting that migrants are extending their search for suitable stopover habitat into areas of the peninsula where availability is greater.  Coupled with accelerated habitat loss within the concentration area between the survey periods, our data suggest that raptors are responding to the degraded landscape by exhibiting greater variation in habitat use, weaker relationships with specific habitat types, spending more time using habitat and are utilizing portions of the peninsula outside of the traditional concentration area.  These results identify the need for conservation and protection of priority stopover areas and a diversity of habitats throughout the entire Cape May stopover, including the expansion of regulatory protection for habitats as far north as 20km from the lower 10km concentration area of the peninsula. This study also suggests that habitat at both the local and landscape levels influence habitat use and distribution at Cape May Peninsula.

description: Context: Understanding galaxy evolution in dense environments, particularly proto-clusters, is crucial for studying mechanisms driving star formation and quenching. Aims: This study examines how two proto-cluster over-densities at 3 < z < 4 impact star formation rate (SFR), stellar mass, and morphology, focusing on quenched galaxies. Methods: We identified proto-cluster over-densities in the Chandra Deep Field South (CDFS) and Ultra Deep Survey (UDS) regions of the VANDELS survey. Using spectral energy distribution analysis, Bayesian methods (BEAGLE and BAGPIPES) helped derive best-fit parameters and U-V and V-J rest-frame colours (UVJ), classifying galaxies as quenched or star-forming based on UVJ diagrams and specific star formation rates (sSFR). TNG300 simulations aided interpretation. Results: Two of 13 proto-cluster over-densities host quenched galaxies with red U-V colours, low sSFR, and properties like massive passive galaxies. These quenched members are redder, older, more massive, and more compact. The highest-density peaks at z=3.55 and z=3.43 have dark matter halo masses consistent with proto-clusters and host AGNs, with five and three AGNs, respectively. Compared to field galaxies, these quenched members are in denser environments. TNG300 simulations suggest proto-clusters with quenched galaxies at high redshift evolve to contain more passive galaxies by z=1. Conclusions: The over-densities host massive quenched galaxies and AGNs in their densest peaks. Simulations reveal that sSFR for passive galaxies in proto-clusters was high at z=6, with median mass growth rates of 96% from z=6 to z=3. Conditions for mass assembly likely involve galaxy interactions and high gas accretion in dense environments. Black hole growth and AGN feedback appear to drive quenching at z=3, aligning with the properties of quenched galaxies observed in our study.

Cross layer network architecture for efficient packet forwarding in wireless networks
Creators: name: Ganu, Sachin
Publisher: name: No Publisher Supplied
Year: 2007

description: With the evolution of 802.11-based wireless networks from hotspots to mesh networks, there has been a tremendous increase in the number of wireless users and density of deployments. Consequently, current wireless network face several problems due to interference, uncoordinated medium access, packet processing overheads at each hop and sub-optimal route selection. While radio technologies continue to improve speeds upto hundred megabits per second, the inadequacies of medium access and routing protocols severely impact the overall network capacity and end-user experience.In this thesis, we focus on improving the scalability and packet forwarding efficiency of multihop wireless networks.We introduce a self-organizing hierarchical ad-hoc network design (SOHAN) based on a three-tier hierarchy with dedicated forwarding nodes to address the scalability of existing multihop networks. We focus on realistic system design considerations and develop a Linux-based system prototype including novel protocols for bootstrapping, discovery and topology control to enable hierarchical self-organization. Experimental and simulation-based evaluations indicate a 2.5 times performance improvement over flat network models.We address packet forwarding inefficiencies of existing techniques over multihop networks due to queuing, contention and reprocessing at each hop and propose an interface contained forwarding architecture (ICF) using a combination of cut-through MAC protocol and label-based forwarding to enable "atomic" channel access for downstream transmissions and reduce self-interference. Next, we design a cross layer enabled cut through architecture (CLEAR) that extends the ICF mechanism with novel airtime metric-based route selection to mitigate the interference between flows. We further outline a time-based coordination scheme using soft reservations during route discovery phase to coordinate multihop "burst" transfers amongst flows. This model can be adapted to support differentiated services and provide a "low-latency socket" for real-time traffic over multiple hops. Our work can be the basis for a switched multihop wireless network design that enables conflict-free transfers resulting in efficient utilization of channel capacity and providing a viable alternative to wired network deployments.A substantial contribution of this thesis also includes the design and development of the ORBIT wireless testbed with focus on cross-layer experimental framework to facilitate rapid prototyping of wireless protocols and experimental evaluations at scale.
Stable isotopic response to the late Eocene extraterrestrial impact events
Creators: name: Pusz, Aimee E.
Publisher: name: No Publisher Supplied
Year: 2007

description: Two large and near synchronous late Eocene (~35.4 - 35.5 Ma based on radiometric ages) impact events (Popigai and Chesapeake Bay) produced well-preserved structures, yet the environmental response to these impacts is poorly understood. Impact events generate ejecta deposits that surround source craters creating characteristic strewn fields. The Chesapeake Bay and Popigai impactors produced strewn fields that serve as stratigraphic markers for these impact events and the late Eocene. The late Eocene global temperature history and carbon budget are poorly constrained because of sparsely sampled ??18O and ??13C records. In this thesis: 1) the Chesapeake Bay microtektite layer is shown to be stratigraphically younger than the Popigai cpx-bearing (or microkrystite) layer, by ~ 4 kyr; 2) a first order correlation of the late Eocene ejecta layers identified in ODP Site 1090 to the geomagnetic polarity timescale in Chron C16n.1n (279 mbsf) is provided with a corresponding magnetochronologic age of 35.43 Ma, consistent with published radiometric ages; 3) new stable isotopic data is presented from Site 1090 and DSDP Site 612 that show a large and transient ??13C excursion (~0.5 0/00) associated with the impacts. At Site 1090, late Eocene benthic foraminifera are well preserved, the identified ejecta horizon is marked by an Ir anomaly (~950 pg/g), and the published magnetostratigraphic age control is excellent. Site 1090 ??13C and ??18O records of benthic foraminifera across the ejecta layer from 34.6 - 35.8 Ma (8 kyr sampling) and 33.7 - 36 Ma (16 kyr sampling) and a high-resolution (2 kyr sampling) bulk-carbonate record (278 - 279.5 mbsf) are presented. Coeval benthic foraminiferal records show a ??13C excursion from: 1) new benthic data from Southern Ocean Site 1090 show a 0.5 0/00 anomaly; 2) new benthic data from New Jersey slope Site 612 show a 0.5 0/00 change, though this record is partially truncated by an unconformity; 3) Southern Ocean Site 689 published data shows a 1.0 0/00 excursion; and 4) Pacific Ocean Site 1218 published data shows a 0.4 0/00 anomaly. The ??13C excursion is suggested to reflect a perturbation in the global carbon cycle and to be directly related to the late Eocene impactor(s).
Nonlinear stochastic dynamics of a nanomechanical resonator coupled to a single electron transistor
Creators: name: Ramakrishnan, Subramanian
Publisher: name: No Publisher Supplied
Year: 2007

description: Nanoelectromechanical systems (NEMS) comprise nanometer to micrometer scale mechanical oscillators coupled to electronic devices of comparable dimensions. NEMS have great potential for sensor applications as well as for exploring fundamental physics. The dynamics of a nanomechanical resonator coupled to a single electron transistor (SET) is considered in the Duffing regime using a master equation approach and a Langevin approach. In the first approach, the master equations are derived and solved using a finite element method as well as a moment approximation method for both the single-well and the (inverted) double-well Duffing potentials. It is observed that the SET damps the resonator motion much more effectively in the single-well Duffing case in comparison with the linear case. In the double-well case we observe the existence of a limit cycle wherein the SET and the resonator exist in a state of dynamic equilibrium. This is followed by the onset of instability in the numerical solutions. The results from the master equation approach are used in a numerical fitting procedure to characterize the damping term in the averaged equations of motion of the system. It is observed that a linear damping term provides the best fit in all cases except for the strongly nonlinear regime. Based on this result, a Langevin equation is written down from which a Fokker-Planck equation is derived for the system. The Fokker-Planck equation is solved analytically, in closed form, for the steady state. In the time dependent case, the equation is solved using a finite element method and the results are shown to be in qualitative agreement with those obtained using the master equation approach. Therefore it is established that the SET-resonator system attains a steady state much more rapidly in the single-well Duffing regime. Finally, the steady state analytical solution to the Fokker-Planck equation is utilized to show that the steady state effective temperature is lower in the presence of the single-well Duffing nonlinearity.

In November 1912, an announcement appeared in the Scripps’s weekly Chicago Day Book as well as in numerous other daily papers: as “a moving picture expert,” Price would be writing “The Movies” column of “personality sketches” of actors and actresses because the movies now were “the biggest, most popular amusement in the world” (“The Movies”). Apparently, she lived in Chicago as the 1912-1914 city directories listed her as a reporter there (Olsson 347).

description: We experimentally study the evolution of the magnetic moment $m$ and exchange interaction $J$ as a function of hydrostatic pressure in the zero-field helimagnetic phase of the strongly correlated electron system MnSi. The suppression of magnetic order at $\approx 1.5$~GPa is shown to arise from the $J$ collapse and not from a quantum fluctuations induced reduction of $m$. Our work provides benchmarks for first principles theories that are challenged by the presence of strong correlations and the possible role of Hund's coupling. In addition, our experimental data are consistent with a reorientation of the magnetic propagation wavevector recently evidenced above $\approx 1.2$~GPa. This result calls for a thorough investigation of the crystal structure in this pressure range.

Design for an inexpensive software solution to eye-gaze tracking as an alternative computer input device
Creators: name: Exum, Maynard
Publisher: name: No Publisher Supplied
Year: 2008

description: Eye tracking has been a topic of interest in a number of different fields for many years.  This thesis explores a few of the many eye-gaze tracking techniques that are currently available and also takes a broad look at the problems that plague most, if not all, of the solutions in the field.  There are a few basic shortcomings in most existing eye trackers.  In particular, the majority of eye trackers on the market are either too expensive, too complicated (for the average consumer) to use, or uncomfortable for the user; and frequently, tracking systems suffer from more than one of these design flaws.  In addition to these issues, almost all of the systems surveyed in this thesis neglect to incorporate a solution that addresses the need to turn the tracking feature off when the user no longer wishes to control the system.  The system implemented and proposed in this thesis was designed with the intention of managing each of these issues.  By using an ambient light process with a feature-based algorithm, the solution promises to keep the overall cost of the system low and to make it comfortable for the user.  In addition, the system uses a remote camera location and a dwell time selection method to ensure that it feels natural to the user when in use.  Finally, the system incorporates a "stateful" tracking design to turn tracking on and off, in an effort to mitigate the "Midas Touch" problem which has probably done most to impede the growth of eye tracking as a practical method for user input to date.  The proposed improvements and design elements presented in this thesis expect to strengthen the argument for eye tracking as an alternative user input device on computers.
Asymptotic perturbation formulas for the effect of scattering by small objects:
Creators: name: Hansen, Derek J.
Publisher: name: No Publisher Supplied
Year: 2008

description: This thesis is a study of the asymptotic perturbation formulas that result from electromagnetic (or acoustic) wave scattering by small, penetrable objects. The ultimate purpose of these formulas is to aid in solving the inverse problem of reconstructing small inhomogeneities embedded within an otherwise known background medium.For simplicity, we consider the time-harmonic, transverse magnetic setting, in which case the scalar electric field satisfies a two-dimensional Helmholtz equation.We first derive, in the case of fixed frequency, a rigorous asymptotic formula for the boundary field perturbation caused by small inhomogeneities of arbitrary shape within a bounded domain.We then derive formal asymptotic formulas in thecase where frequency is allowed to grow as the size of a single, smooth inhomogeneity tends to zero.For high frequencies, we use the technique of geometric optics to derive an integral formula for the scattered field, which we then simplify by a stationary phase analysis. The resulting asymptotic formula is ripe with geometric information to aid in solving the inverse problem.In a step toward a rigorous proof of this high frequency asymptotic formula, we prove an estimate of a Sobolev norm of the scattered field in the case of a penetrable, though conducting, circular scatterer.

description: Motivated by the difference between the fluxes of sub-PeV Galactic diffuse gamma-ray emission (GDE) measured by the Tibet AS$γ$ experiment and the LHAASO collaboration, our study constrains the contribution to the GDE flux measured by Tibet AS$γ$ from the sub-PeV gamma-ray sources in the first LHAASO catalog plus the Cygnus Cocoon. After removing the gamma-ray emission of the sources masked in the observation by Tibet AS$γ$, the contribution of the sources to the Tibet diffuse flux is found to be subdominant; in the sky region of $25^{\circ} < l < 100^{\circ}$ and $|b| < 5^{\circ}$, it is less than 26.9% $\pm$ 9.9%, 34.8% $\pm$ 14.0%, and ${13.5%}^{+6.3%}_{-7.7%}$ at 121 TeV, 220 TeV, and 534 TeV, respectively. In the sky region of $50^{\circ} < l < 200^{\circ}$ and $|b| < 5^{\circ}$, the fraction is less than 24.1% $\pm$ 9.5%, 27.1% $\pm$ 11.1% and ${13.5%}^{+6.2%}_{-7.6%}$. After subtracting the source contribution, the hadronic diffusive nature of the Tibet diffuse flux is the most natural interpretation, although some contributions from very faint unresolved hadronic gamma-ray sources cannot be ruled out. Different source-masking schemes adopted by Tibet AS$γ$ and LHAASO for their diffuse analyses result in different effective galactic latitudinal ranges of the sky regions observed by the two experiments. Our study concludes that the effect of the different source-masking schemes leads to the observed difference between the Tibet diffuse flux measured in $25^{\circ} < l < 100^{\circ}$ and $|b| < 5^{\circ}$ and LHAASO diffuse flux in $15^{\circ} < l < 125^{\circ}$ and $|b| < 5^{\circ}$.

Dose- and rate-dependent effects of cocaine on striatal neurons related to licking
Creators: name: Mittler, Taliah
Publisher: name: No Publisher Supplied
Year: 2008

description: To examine the role of striatal mechanisms in cocaine-induced stereotyped licking, the activity of lick-related neurons in the ventrolateral striatum of awake, freely moving rats engaged in licking was recorded before and after cocaine administration (0, 5, 10 and 20 mg/kg). Relative to zero dose, cocaine reduced lick duration and increased interlick interval, particularly at the high dose, but did not affect licking rhythm. Stereotyped licking was induced only by the high dose, evident by an increase in the number of licks in the absence of water delivery. Firing rates (FR) of striatal neurons phasically related to licking were compared between matched licks before and after injection, minimizing any influence of sensorimotor variables on changes in firing. Both increases and decreases in average FR were observed post-drug, exhibiting a dose-dependent pattern that strongly depended on pre-drug FR. At the middle and high doses relative to the zero dose group, the average FR of slow firing neurons were increased by cocaine, resulting from a general elevation of movement-related FR. By contrast, fast firing neurons showed decreased average FR only in the high dose group, with reduced FR across the entire range for these neurons. Additionally, without any drug present (prior to drug injection) FR were positively related to the strength of the correlation of FR with lick duration. Changes in behavioral correlations were demonstrated over time with no drug present (for slow firing neurons), and following cocaine administration (for slow firing neurons at all doses, and for fast firing neurons only at the high dose). Thus, differences were observed between slow and fast firing neurons in drug effects on FR, in the strength of their behavioral correlations and with respect to changes in their behavioral correlations, suggesting that fast firing neurons may be more strongly involved in the processing of movement parameters. These findings suggest that at the high dose, increased phasic activity of slow firing striatal neurons and simultaneously reduced phasic activity of fast firing striatal neurons may contribute, respectively, to the continual initiation of stereotypic movements and the absence of longer, more global movements.
On the questions of local and global well-posedness for the hyperbolic PDEs occurring in some relativistic theories of gravity and electromagnetism
Creators: name: Speck, Jared R.
Publisher: name: No Publisher Supplied
Year: 2008

description: The two hyperbolic systems of PDEs we consider in this work are the source-free Maxwell-Born-Infeld (MBI) field equations and the Euler-Nordstr??m system for gravitationally self-interacting fluids. The former system plays a central role in Kiessling's recently proposed self-consistent model of classicalelectrodynamics with point charges, a model that does not suffer from the infinities found in the classical Maxwell-Maxwell model with point charges. The latter system is a scalar gravity caricature of the incredibly more complex Euler-Einstein system. The primary original contributions of the thesis can be summarized as follows:1) We give a sharp non-local criterion for the formation of singularities in plane-symmetric solutions to the source-free MBI field equations. We also use a domain of dependence argument to show that 3-d initial data agreeing with certain plane-symmetric data on a large enough ball lead to solutions that form singularities in finite time. This work is an extension of a theorem of Brenier, who studied singularity formation in periodic plane-symmetric solutions.2) We prove well-posedness for the Euler-Nordstr??m  system with a cosmological constant k (EN_k) for initial data that are an H^N perturbation (not necessarily small) of a uniform, quiet fluid, for N [greater than]= 3. The method of proof relies on the framework of energy currents that has been recently developed by Christodoulou. We turn to this method out of necessity: two common frameworks for showing well-posedness in H^N, namely symmetric hyperbolicity and strict hyperbolicity, do not apply to the EN_k system, while Christodoulou's techniques apply to all hyperbolic systems derivable from a Lagrangian, of which the EN_k system is an example.3) We insert the speed of light c as a parameter into the EN_k system (and designate the family of systems EN_k^c) in order to study the non-relativistic limit c to infinity. Taking the formal limit in the equations gives the Euler-Poisson system with a cosmological constant (EP_k). Using energy currents, we prove that for fixed initial data, as c goes to infinity, the solutions to the EN_k^c system converge uniformly on a spacetime slab [0,T] x R^3 to the solution of the EP_k system.

description: This report constitutes the Doctoral Dissertation for Munevver Mine Subasi and consists of three topics: sharp bounds for the probability of the union of events under unimodality condition, convexity theory in probabilistic constrained stochastic programming and strong unimodality of multivariate discrete distributions.We formulate a linear programming problem for bounding the probability of the union of events, where the probability distribution of the occurrences is supposed to be unimodal with known mode and some of the binomial moments of the events are also known. Using a theorem on combinatorial determinants we fully describe the dual feasible bases of a relaxed problem. We present closed form lower and upper bounds for the probability of the union based on two (not necessarily consecutive) as well as first three binomial moments of the random variables involved. We also present upper bounds for the probability of the union based on first four binomial moments. We give a dual method to find customized algorithmic solution of the LP's involved. Numerical examples show that by the use of our bounding methodology, we obtain tighter bounds for the probability of the union.Next we investigate the convexity theory of programming under probabilistic constraints. Pr'ekopa cite{prekopa73,prekopa95} has proved that if $T$ is an $rtimes n$ random matrix with independent, normally distributed rows such that their covariance matrices are constant multiples of each other, then the function $h(vx)=P(Tvx leq vb)$ is quasi-concave in $R^n$, where  $vb$ is a constant vector. We prove that, under same condition, the converse is also true, a special quasi-concavity of $h(vx)$ implies the above-mentioned property of the covariance matrices.Finally we present sufficient conditions that ensure the strong unimodality of a multivariate discrete distribution and give an algorithm to find the maximum of a strongly unimodal multivariate discrete distribution. We also present examples of strongly unimodal multivariate discrete distributions.

description: In this study, I revealed changes in academic motivational components while students were completing an academic task. The sample consisted of teacher education graduate students enrolled in an educational assessment summer course. The academic task was an assessment portfolio that the students could use after the course when they applied for teaching jobs and as an aid in their teaching. The task was designed to be meaningful to the students and to enhance their intrinsic motivation. It was constructivist in nature and allowed the students to practice the skills they learned within their own fields. I measured value and expectancy components of motivation at a task-specific level while students completed this assignment over the duration of the 4-week summer course. I measured academic motivation at a task-specific level to provide empirical support for modern expectancy-value theory. Because motivational constructs were found to have more predictive power when measured at a domain-specific measure compared to global measures, measuring the motivational constructs of expectancy and value at a task-specific level was expected to significantly predict academic performance and self-reported behavior as well. Additionally, measuring motivational constructs at a task-specific level presented a different way to examine motivational constructs. The theorists of modern expectancy-value theory have demonstrated links that exist between the motivational constructs described in their theory and those in other academic motivational theories. In this study, I provided additional support to this effort by demonstrating that the description of intrinsic value more closely matched that of constructs from other theoretical perspectives. Intrinsic value is a component within task value in expectancy-value theory defined as the enjoyment one experiences while completing a task and the interest one has in the task. I hypothesized that interest and enjoyment, constructs used interchangeably to define intrinsic value, were distinct constructs that varied during the completion of an academic task. The results of this study supported this hypothesis. The results also showed that the constructs varied in opposite directions over time as the students completed the academic task. These findings support changes in the conceptualization of intrinsic value in order to incorporate these distinct constructs into the model.

The great powers and the establishment of security regimes:

description: Over the past two centuries, international relations have been marked by greater institutionalization. This trend has characterized not only trade and economic relations but also such highly sensitive areas as security and political-military cooperation among states. The institutionalization of security issues by means of establishing global and regional security organizations, such as the UN and NATO, or issue-specific security regimes, such as the non-proliferation regime, raises important questions about the changing nature of international relations. Why do states cooperate to establish international security regimes in the first place? Why do they succeed in establishing security regimes in some cases and fail in others?In my dissertation I addresses these questions by studying several attempts made by the great powers between 1792 and 1815 to form an early case of a security regime, known as the Concert of Europe. As an example of successful great power cooperation in security issues, the study of the Concert has recently acquired a great deal of political as well as academic importance, leading to the emergence of substantial scholarship among historians and political scientists. The literature on the Concert is abundant, however, it suffers from a major weakness: it offers bivariate explanations of regime formation, emphasizing either power, interests or knowledge as the key variable.  The same weakness characterizes the regime scholarship in general. I redress these weaknesses in the scholarship by using a multivariate approach to the study of the formation of the Concert. I focus on the interplay of four key factors -- power, interests, knowledge and leadership in the creation of the European Concert. I do not treat the formation of the Concert of Europe as a single case study. The formation of the Concert constitutes a series of mini-cases and thus may be viewed as a small-N study. Between 1792 and 1815 the great powers went through several rounds of negotiations over the creation of a European concert, which corresponded to the formation of several anti-French coalitions. The Second and the Third Coalitions represent cases of failure to form a European concert, while the Grand Coalition (1814-1815) is a clear-cut case of success. The findings reached on the basis of all four case-studies are numerous and shed new light on the relative role played by the key major factors -- power, interests, knowledge and leadership in the creation of security regimes. As a theory-generating small-N study, the findings of the dissertation may be tested in other cases of security regime formation such as the creation of the League of Nations (1919) or the United Nations (1945).

description: Obesity continues to be a major public health issue in the United States. The aims of this study were to investigate whether the dietary resveratrol, black tea extract, caffeine and their combination could show anti-obesity effects in CD-1 mice fed with a high-fat diet. Five groups of CD-1 mice, with 10 mice in each group, were fed with 0.06 % resveratrol (RTL), 0.2 % black tea extract (BTE) and 0.05 % caffeine (CF), as well as their combination containing 0.03 % RTL, 0.1 % BTE and 0.025 % CF for 16 weeks. Mice on the CF diet significantly (p[less than]0.01) reduced body weight gain by 46 %, while those on the RTL, BTE, CF and the combination diets showed reductions by 12 %, 14 % and 28 %, respectively. There were significant inhibitions in parametrial (77 %), retroperitoneal (77 %) fat pads and brown adipose tissue (57 %) for mice on CF group.Mice on the BTE diet showed significant (p[less than]0.05) inhibition of leptin levels in plasma by 59 %, while those on the CF and combination diets demonstrated significant (p[less than]0.01) inhibition by 88 % and 79 %, respectively. These results suggest that diets with RTL, BTE, and CF reduced body weight gain, fat tissue depositions and leptin levels in female CD-mice during the 16-week animal studies.

Developing methods for design and analysis of continuous mixers through 3D numerical simulation of flow and mixing

description: Design, scale up and selection of alternative geometries for dough mixers in order to achieve a well mixed final product with consistent rheological character is a major challenge in the food industry. The objective of this work is to develop methods to formulate design rules for continuous mixers and identify continuous mixer geometries with similar mixing performance as a model batch mixer using 3D numerical simulations.FEM simulations were performed with Polyflow (Fluent Inc.) which uses a mixed Galerkin formulation of the isothermal governing equations of motion and continuity. 3D continuous mixer geometries that simulate a 2" Readco Twin Screw mixer with three different paddle configurations were developed and flow profiles and mixing efficiencies were predicted. Accurate predictions of the flow profiles in a continuous mixer were attained by optimizing the FEM mesh, flow geometry and operating conditions through convergence analysis of velocity and pressure. The predictions were validated with favorable comparisons to experimentally observed velocities that demonstrated the accuracy of the predicted velocities increased with increasing length of mixer geometry, showing the importance of considering the axial flow in a continuous.Using the calculated flow profiles, trajectories for material points with random initial positions were calculated to predict mixing efficiencies. Segregation scale, mean logarithm of stretching, mean instantaneous efficiency and time averaged efficiency, along with the shear rates and mixing index were used to evaluate mixing. The forward conveying paddle configuration provided the best mixing efficiency when compared to neutral and reverse conveying paddle arrangements and the continuous mixer was also shown to be significantly better than a batch mixer for the same time of operation. Existing numerical techniques that can solve flow problems with moving objects in the flow domain cannot simulate the flow of viscoelastic materials. New techniques were evaluated in this research to simulate the flow and mixing of viscoelastic materials in the twin screw mixing geometry.
