description: Compressing or cooling a fluid typically enhances its static interparticle correlations. However, there are notable exceptions. Isothermal compression can reduce the translational order of fluids that exhibit anomalous waterlike trends in their thermodynamic and transport properties, while isochoric cooling (or strengthening of attractive interactions) can have a similar effect on fluids of particles with short-range attractions. Recent simulation studies by Yan et al. [Phys. Rev. E 76, 051201 (2007)] on the former type of system and Krekelberg et al. [J. Chem. Phys. 127, 044502 (2007)] on the latter provide examples where such structural anomalies can be related to specific changes in second and more distant coordination shells of the radial distribution function. Here, we confirm the generality of this microscopic picture through analysis, via molecular simulation and integral equation theory, of coordination shell contributions to the two-body excess entropy for several related model fluids which incorporate different levels of molecular resolution. The results suggest that integral equation theory can be an effective and computationally inexpensive first-pass tool for assessing, based on the pair potential alone, whether new model systems are good candidates for exhibiting structural (and hence thermodynamic and transport) anomalies.

description: Σκοπός της παρούσας εργασίας ήταν η αξιολόγηση έξι υβριδίων βιομηχανικής τομάτας ως προς την καταλληλότητά τους ως αρχικό υλικό μέσα στο οποίο θα μπορούσε να ξεκινήσει η επιλογή για περαιτέρω βελτίωση. Εγκαταστάθηκαν δύο πειράματα στην περιοχή της Ηλείας με βάση το επαναλαμβανόμενο κυψελωτό σχέδιο R-3. Το πρώτο κυψελωτό πείραμα περιελάμβανε τρία υβρίδια πάστας (CXD 206, 094 F1,Gibson) και το δεύτερο τρία υβρίδια που προορίζονται για ψιλοκομμένο προϊόν-αγγλικός όρος "diced"(CXD 219, 036F1, 1120). Τα χαρακτηριστικά που μετρήθηκαν ήταν η απόδοση και η πρωιμότητα (ως ημέρες από την μεταφύτευση μέχρι την άνθηση), στο σύνολο των φυτών των υβριδίων. Μετρήθηκαν επίσης το βάρος καρπού, σε αντιπροσωπευτικό δείγμα των υβριδίων και τα ποιοτικά χαρακτηριστικά του καρπού (στερεά διαλυτά συστατικά, περιεκτικότητα σε ασκορβικό οξύ και νιτρικά, pH και οξύτητα, ξηρά ουσία) σε τρία φυτά από κάθε υβρίδιο. Με βάση την αξιολόγηση ως προς τα τρία συστατικά του παραγωγικού δυναμικού, διαπιστώθηκε υπεροχή των υβριδίων Gibson και 1120. Από τα υβρίδια αυτά προκύπτουν και τα περισσότερα επιλεγόμενα φυτά με βάση τον κινούμενο δακτύλιο και κάτω από πίεση επιλογής 14,3%. Τα αποτελέσματα για την πρωιμότητα, το βάρος καρπού και τα ποιοτικά χαρακτηριστικά μπορούν να βοηθήσουν συμπληρωματικά στην διαδικασία της επιλογής.
description: The aim of the present study was the evaluation of six processing tomato hybrids, as being suitable as starting material in the selection procedure. Two experiments were established in the area of Ilias prefecture, according to the replicated honeycomb design R-3. The first experiment included three tomato hybrids suitable for the production of tomato paste (CXD 206, 094 F1, Gibson) while the second experiment included three tomato hybrids suitable for the production of diced tomato product (CXD 219, 036 F1, 1120). The characteristics measured were yield and earliness (as days from the transplant until flowering), in the whole number of the plants. The fruit weight was measured also, in a partial number of plants, and the quality characteristics of the fruit such as total soluble solids (brix), the amount of ascorbic acid and nitrates, pH and oxicity and dry matter, in three plants of each hybrid. Based on the evaluation of the hybrids using the partition of crop yield potential into three components, the hybrids Gibson and 1120 were found to be superior. From these hybrids comes the majority of the selected plants according to the moving circle, using a selection pressure of 14,3%. The results for the earliness, the fruit weight and the quality characteristics of the fruit can provide a supplemental help in the selection process.

description: Múltiples estudios relacionan la dieta y las enfermedades crónicas como las cardiovasculares, obesidad, diabetes mellitus y algunos tipos de cáncer y han puesto de manifiesto que dieta y salud caminan juntas. Además, a diferencia de otros factores como los genéticos, en el caso de la dieta tenemos la posibilidad de modificarla como una medida preventiva o para retrasar los efectos de la enfermedad o, simplemente tratarla.

No existen alimentos buenos y malos; todos ellos están concebidos para formar parte de una dieta equilibrada mientras se consumen con moderación. Comer es uno de los grandes placeres de la vida y es importante que la alimentación además de equilibrada y variada, sea agradable y que tenga una calidad sensorial que la haga apetecible. En aquellos casos en que es necesario realizar una modificación dietética para prevenir o tratar una enfermedad, el desafío para los profesionales de la salud y la nutrición es aún mayor. Además de aconsejar la mejor calidad nutricional resulta fundamental que ese consejo mantenga el derecho a alcanzar la gratificación y el placer al comer.

description: Seawater chlorination has three main industrial uses: disinfection of water and installations, control of biofouling, and preventing the transport of aquatic invasive species. Once in contact with seawater, chlorine reacts rapidly with water constituents (e.g. bromide ions, ammonia, and nitrogen-containing compounds) to form a range of oxidative species (e.g. bromine and N-haloamines), termed “chlorine-produced oxidants” (CPOs) or “total residual oxidants” (TRO). The chemical nature of CPOs and their concentration are a function of two categories of parameters related to treatment modality (e.g. chlorine dose) and water quality (e.g. temperature, pH, ammonia concentration, and organic constituents). The chlorination process may result in continuous or intermittent releases of CPOs in seawater. The reactivity and potential ecotoxicity of CPO species largely depend on their physical and chemical properties. Therefore, evaluation of the biocidal effectiveness of chlorination and its potential impacts requires not only determining the sum of CPOs (via a bulk parameter), but also their chemical speciation. The aim of this article – which is the first of a trilogy dedicated to the chemical speciation of CPOs in seawater – is to provide an overview of current knowledge about chlorine chemistry in seawater and to discuss the biocidal efficacy and the environmental fate of resulting CPOs. The 2nd and 3rd articles delineate a comprehensive and critical review of analytical methods and approaches for the determination of CPOs in seawater.

description: Black hole. Neutron star binary systems are one of the most promising sources of gravitational radiation for detection by laser interferometric detectors, such as LIGO,VIRGO, TAMA and GEO600. In this thesis we study the evolution and emission of gravitational radiation by these binaries. Using the first post‐Newtonian correction of the orbital motion and modeling the neutron stars as compressible ellipsoids,obeying a polytropic equation of state, we study the evolution of these binaries for different values of several physical parameters (polytropic index, mass ratio and neutron star radius). Furthermore, we calculate the gravitational waveforms and study the modes of which they consist.

description: Low-molecular-weight polyamines such as spermine and spermidine are ubiquitous in all forms of life and are involved in many cellular functions such as cell growth. Pathological altered polyamine concentration are associated with a variety of diseases. We thus aimed for their analysis from serum using reversed-phase liquid chromatography coupled to detection with quadrupole time-of-flight mass spectrometry. We tested 15 polyamines for their response, developed a multiplex target method, and refined it for five active substances including spermine and spermidine, which induced expression of the autophagy protein Atg8/LC3-II in a neuronal cell line.

description: Signatures of self-organized criticality (SOC) have recently been observed in an ultracold atomic gas under continuous laser excitation to strongly-interacting Rydberg states [S. Helmrich et al., Nature, 577, 481--486 (2020)]. This creates a unique possibility to study this intriguing dynamical phenomenon, e.g., to probe its robustness and universality, under controlled experimental conditions. Here we examine the self-organizing dynamics of a driven ultracold gas and identify an unanticipated feedback mechanism, which is especially important for systems coupled to thermal baths. It sustains an extended critical region in the trap center for a notably long time via hydrodynamic transport of particles from the flanks of the cloud toward the center. This compensates the avalanche-induced atom loss and leads to a characteristic flat-top density profile, providing an additional experimental signature for SOC and minimizing effects of inhomogeneity on the SOC features.

Applying this result to a cosimplicial commutative algebra A^* over a field of characteristic zero, we exhibit a canonical unital C-infinity structure on Tot(A^*), which is unital if A^* is; in particular, we obtain a canonical C-infinity structure on the cochain complex of a simplicial set.

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1991
Subjects: subject: Transportation Engineering

description: The objective of the survey was to establish 1991 safety belt and child safety seat usage rates in Kentucky. Data were collected at 100 sites and combined based on vehicle miles traveled for a given type of highway, rural or urban location, and county population category. Also included in this report is an analysis of accident records evaluating the effectiveness of safety belts.  Statewide usage rates were 39 percent for drivers and front-seat passengers (over 19 years of age) and 57 percent for children under four years of age (front and rear seats). Driver usage rates had increased significantly in 1991 compared to 1990. Rates were highest on interstate highways and lowest on rural, non-interstate highways.  Benefits in the reduction of injuries for occupants involved in police-reported accidents wearing a safety belt or in a safety seat were shown through the analysis of accident records. For example, a 49 percent reduction in fatal or incapacitating injuries was determined for drivers wearing a safety belt compared to those who were not restrained.  The increased usage that resulted in Fayette County and Louisville after enactment of local mandatory usage laws was shown. The recommendation is that a statewide mandatory safety belt law should be passed or, in lieu of a statewide law, additional local governments should pass such a law.

Ακόμα κι αν το όραμά της φαντάζει απραγματοποίητο, το αίτημα και η προσπάθειά της διαρκούς προσπέλασής της αποτελεί ηθικό καθήκον, που υπαγορεύεται από την πρακτική λειτουργία του Λόγου. Ο φιλόσοφος της κατηγορικής προσταγής επεξεργάζεται και διατυπώνει-έστω και εν σπέρματι-μια κανονιστική θεωρία διεθνών σχέσεων, της οποίας πυρηνική αρχή και ταυτόχρονα τελικός σκοπός είναι η διαρκής ειρήνη.

description: Kant argues for a stable peace among states. In order to achieve this goal, he suggests that states join together in order to constitute a league of nations. Nations, as states, can be appraised as individuals, who in their natural condition already wrong one another by being enar one another ; and each of them, for the sake of its security, can and ought to require the other to enter with it into a constitution similar to a civil constitution, in which can be assured of its right. Kant claims that states necessarily wrong one another in a condition of independence from external laws. For that reason, in order to promote their own safety, they should leave their state of nature and enter a constitution similar to a civil society. Just like individuals prefer to leave their state of nature in order to establish a civil society, particular states choose to enter into a civil constitution to guarantee their rights and avoid the permanent threat of war. However this elague should not be a state above other states. In a league of nations, the states leave their barbarous state of nature to form a civil constitution in order to avoid war. Kant claims that this civil constitution should be thought of as necessary. In order to be effective against war, kant distinguishes his league of nations from a pact of peace. The league of nations and the idea of a mere peace pact that does not guarantee a lasting peace : Then, in accordance to reason, the states leave their lawless condition to enter a state of nations that will include all the nations of the earth

description: Increased emphasis on highway maintenance and the need to accomplish the maintenance programs as efficiently as possible, prompted this study. The objectives of the study addressed herein are the identification of maintenance activities performed by contract, determination of equivalent levels of service between contract performed and in-house performed activities, cost comparison of those activities, and recommendations to implement the findings.  Findings are that activities routinely performed by contract are cost efficient. A formal make-versus-buy decision making process should be developed. The process should be made available to District personnel and the make-versus-buy decision made at that level. Decision making processes have been developed by other agencies and one is reviewed herein.

description: We present the spectral analysis of duration-integrated broadband spectra (in $\sim30 $keV$-200 $MeV) of 15 bright BATSE gamma-ray bursts (GRBs). Some GRB spectra are very hard, with their spectral peak energies being above the BATSE LAD passband limit of $\sim$2 MeV. In such cases, their high-energy spectral parameters (peak energy and high-energy power-law indices) cannot be adequately constrained by BATSE LAD data alone. A few dozen bright BATSE GRBs were also observed with EGRET's calorimeter, TASC, in multi-MeV energy band, with a large effective area and fine energy resolution. Combining the BATSE and TASC data, therefore, affords spectra that span four decades of energy ($30 $keV$-200 $MeV), allowing for a broadband spectral analysis with good statistics. Studying such broadband high-energy spectra of GRB prompt emission is crucial, as they provide key clues to understanding its gamma-ray emission mechanism. Among the 15 GRB spectra, we found two cases with a significant high-energy excess, and another case with a extremely high peak energy (\epeak $\gtrsim$ 170 MeV). There have been very limited number of GRBs observed at MeV energies and above, and only a few instruments have been capable of observing GRBs in this energy band with such high sensitivity. Thus, our analysis results presented here should also help predict GRB observations with current and future high-energy instruments such as AGILE and GLAST, as well as with ground-based very-high-energy telescopes.

description: This report documents a preliminary investigation of Kentucky Rock Asphalt (Kyrock) - as a road surfacing material. The indigenous bituminous impregnated sandstone was widely used as a premium quality skid resistant surfacing material during the first half of this century. Redevelopment efforts gained momentum during the 1960's, but for the last twenty years interest has waned.  Laboratory tests were conducted on the Kyrock to determine its applicability in bituminous surface mixes by blending Kyrock with virgin materials in a similar manner as adding recycled asphalt pavement. The findings indicated it was feasible to blend Kyrock and a continuation proposal was presented.

The data on $^{6}$Li,$^{6}$He+$^{28}$Si are analyzed in the framework of the microscopic optical potential with real and imaginary parts obtained with a help of the double-folding procedure and by using the current models of densities of the projectile nuclei. Besides, the microscopic double-folding Coulomb potential is calculated and its effect on cross sections is compared with that when one applies the traditional Coulomb potential of the uniform charge distribution. The semi-microscopic potentials are constructed from both the renormalized microscopic potentials and their derivatives to take into account collective motion effect and to improve an agreement with experimental data.

description: Supermassive black holes lying in the center of galaxies can launch relativistic jets of plasma along their polar axis. The physics of black-hole jets is a very active research topic in astrophysics, owing to the fact that many questions remain open on the physical mechanisms of jet launching, of particle acceleration in the jet, and on the radiative processes. In this work I focus on the last item, and present a review of the current understanding of radiative emission processes in supermassive-black-hole jets.

description: Recent years have witnessed an exponential increase in the research on gold nanoparticles (AuNPs)-based colorimetric sensors to revolutionize point-of-use sensing devices. Hence, this review is compiled focused on current progress in the design and performance parameters of AuNPs-based sensors. The review begins with the characteristics of AuNPs, followed by a brief explanation of synthesis and functionalization methods. Then, the mechanisms of AuNPs-based sensors are comprehensively explained in two broad categories based on the surface plasmon resonance (SPR) characteristics of AuNPs and their peroxidase-like catalytic properties (nanozyme). SPR-based colorimetric sensors further categorize into aggregation, anti-aggregation, etching, growth-mediated, and accumulation-based methods depending on their sensing mechanisms. On the other hand, peroxidase activity-based colorimetric sensors are divided into two methods based on the expression or inhibition of peroxidase-like activity. Next, the analytes in environmental and food samples are classified as inorganic, organic, and biological pollutants, and recent progress in detection of these analytes are reviewed in detail. Finally, conclusions are provided, and future directions are highlighted. Improving the sensitivity, reproducibility, multiplexing capabilities, and cost-effectiveness for colorimetric detection of various analytes in environment and food matrices will have significant impact on fast testing of hazardous substances, hence reducing the pollution load in environment as well as rendering food contamination to ensure food safety.

description: Photons and electrons are the key quantum media for the quantum information processing based on solid state devices. The essential ingredients to accomplish the quantum repeater were investigated and their underlying physics were revealed. The relevant elementary processes of the quantum state transfer between a single photon and a single electron were analyzed, to clarify the conditions to be satisfied to achieve the high fidelity of the quantum state transfer. An optical method based on the Faraday rotation was proposed to carry out the Bell measurement of two electrons which is a key operation in the entanglement swapping for the quantum repeater and its feasibility was confirmed. Also investigated was the quantum dynamics in the electron-nuclei coupled spin system in quantum dots and a couple of new phenomena were predicted related to the correlations induced by the hyperfine interaction, namely, bunching and revival in the electron spin measurements. These findings will pave the way to accomplish the efficient and robust quantum repeater and nuclear spin quantum memory.

description: Chlorination of seawater forms a range of secondary oxidative species, collectively termed “chlorine-produced oxidants” (CPOs). These compounds do not have the same biocidal efficacy, the same fate and behavior in the marine environment, the same potential formation of chlorination by-products (CBPs), nor the same effects on marine organisms. Their chemical speciation is an important step toward an accurate assessment of the effectiveness of chlorination and the potential impacts of its releases, among others. The aim of this paper - which is the second of a trilogy dedicated to the chemical speciation of CPOs in seawater - is to cover all aspects related to CPOs analysis in seawater, from sampling to instrumental determination. First, it discusses the procedures involved in synthesis, storage, and standardization of analytical standards. Second, it deals with sampling and sample preparation, addressing all relevant issues related to these two key steps. Third, it provides a comprehensive and up-to-date overview of the colorimetric, titrimetric, and electrochemical methods used for CPOs determination and thoroughly discusses their advantages and limitations. Finally, this review ends with some recommendations for progress in the field of CPO analysis with the three aforementioned approaches. Chromatographic and mass spectrometric-based methods will be covered in the third and final article (Part III).

The quadrature discretization method and its applications
Creators: name: Chen, Heli
Publisher: name: University of British Columbia
Year: 2009

description: A discretization method referred to as the quadrature discretization method is introduced and studied in this thesis. The quadrature discretization method is a spectral method based on a grid of points that coincide with the points of a quadrature. The quadrature is based on a set of nonclassical polynomials orthogonal with respect to some weight function over some interval. The method is flexible with respect to the choice of the weight function and quadrature points so that the optimum accuracy and convergence in the solution of differential equations and/or partial differential equations can be obtained. The properties of the quadrature discretization method are studied and compared with classical spectral methods as well as finite difference methods. Several analytic model problems in one and three dimension are studied. The quadrature discretization method competes well with classical spectral methods and is far more superior than the finite difference method. In some cases it provides significant improvement in the accuracy and convergence of the solution of the problem over other methods. The main objective of the quadrature discretization method is to determine the weight function that defines the polynomial basis set and hence the grid points that provide optimum convergence in a given application. The quadrature discretization method is applied to a large class of time dependent Fokker-Planck equations. Several weight functions are used and the results are compared with several other methods. The weight functions that have often provided rapid convergence of the eigenvalues and eigenfunctions of the Fokker-Planck operator are the steady solutions at infinite time. The quadrature discretization method is also employed in the solution of Schrodinger equations. The weight functions that are used are related to the ground state wave functions if known, or some approximate form. The eigenvalues and eigenfunctions of four different potential functions discussed extensively in the literature are calculated and compared with the published values. The eigen-problem of a two-dimensional Schrodinger equation with the Henon-Heiles potential is also calculated with the quadrature discretization method. The rate of convergence of the eigenvalues and eigenfunctions of the Schrodinger equations is very rapid with this approach.

description: The azimuthal substructure observed in some debris disks, as exemplified by epsilon Eridani, is usually attributed to resonances with embedded planets. In a standard scenario, the Poynting-Robertson force, possibly enhanced by the stellar wind drag, is responsible for the delivery of dust from outer regions of the disk to locations of external mean-motion planetary resonances; the captured particles then create characteristic ``clumps''. Alternatively, it has been suggested that the observed features in systems like epsilon Eri may stem from populations of planetesimals that have been captured in resonances with the planet, such as Plutinos and Trojans in the solar system. A large fraction of dust produced by these bodies would stay locked in the same resonance, creating the dusty clumps. To investigate both scenarios and their applicability limits for a wide range of stars, planets, disk densities, and planetesimal families we construct simple analytic models for both scenarios. In particular, we show that the first scenario works for disks with the pole-on optical depths below about ~10^{-4}-10^{-5}. Above this optical depth level, the first scenario will generate a narrow resonant ring with a hardly visible azimuthal structure, rather than clumps. The efficiency of the second scenario is proportional to the mass of the resonant planetesimal family, as example, a family with a total mass of ~0.01 to 0.1 Earth masses could be sufficient to account for the clumps of epsilon Eridani.

description: Motivated by the experiments on the organic compound $(Per)_{2}[Pt(mnt)_{2}]$, we study the ground state of the one-dimensional Kondo lattice model at quarter filling with the density matrix renormalization group method. We show a coupled dimer and bond-order-wave (BOW) state in the weak coupling regime for the localized spins and itinerant electrons, respectively. The quantum phase transitions for the dimer and the BOW orders occur at the same critical coupling parameter $J_{c}$, with the opening of a charge gap. The emergence of the combination of dimer and BOW order agrees with the experimental findings of the simultaneous Peierls and spin-Peierls transitions at low temperatures, which provides a theoretical understanding of such phase transition. We also show that the localized spins in this insulating state have quasi-long ranged spin correlations with collinear configurations, which resemble the classical dimer order in the absence of a magnetic order.
