description: Free bases, oligo- and polynucleotides of thymine and adenine have been used as models for DNA in the study of indirect radiation-induced base and sugar damage. Reactions of OH radicals were investigated. Due to the presence of a small yield of H atoms, the reactions of these species were also studied. In order to generate OH radicals, samples were irradiated in N(,2)O-saturated aqueous solution. The products resulting from the reactions of solute molecules with (.)OH and H atoms were isolated by high performance liquid chromatography and their structures elucidated by capillary gas chromatography-mass spectrometry. Yields of the altered bases and sugars were determined by gas chromatography. Monomeric and novel cross-linked products of thymine and adenine were discovered and characterized. Additionally, thymine radicals were found to abstract hydrogen atoms intramolecularly from an adjacent nucleotide sugar moiety of polynucleotides. This reaction possibly contributes to the formation of strand breaks in DNA which may play a major role in the deleterious effects of ionizing radiation on cells. Mechanisms of product formation are discussed in detail.

description: Investment in research is a primary driver of productivity growth in agriculture. However, in high-income countries, as agriculture’s contribution to national economies declines, many public agricultural research systems face stagnant or falling financial support while research costs continue to rise. Public spending on agricultural research and development in high-income member countries of the Organisation for Economic Co-operation and Development as a whole has fallen in real (inflation-adjusted) terms since at least 2009. At the same time, society’s expectations of food and agricultural systems have evolved to include a broader set of issues.These forces have induced pressure to reform agricultural research policies. Lessons from research policy reforms include accommodating a larger role for private firms in conducting agricultural research, diversifying funding sources to broaden the public research agenda, and providing stronger incentives for producer-levy funding of research.

description: In this work, Five varieties of reinforcing materials (fibers and particles) were each laminated separately with PMMA matrix used for manufacturing trans-tibial prosthetic socket and fabricated using vacuum molding technique. The tensile and fatigue properties of Five trans-tibial prosthetic sockets were studied experimentally, theoretically and by using finite element method (Ansys-11). Results showed that the weakest laminate based on mechanical strength (Tensile strength and Fatigue limit) was [PMMA+8Perlon layers]composite and the highest mechanical strength was found in [PMMA+(3Perlon+2(Carbon +Glass)+3Perlon) layers] composite. Results of finite element method and theoretical calculation also indicate that the [PMMA+(3Perlon+2(Carbon +Glass)+3Perlon) layers] composite has the highest safety factor and the lowest values of both (deformation and failure index) making that composite the best candidate to give better fatigue characteristics of trans-tibial prosthetic socket.

description: The USDA’s Rural Development mission area (RD) implements several loan and grant programs to support businesses in rural areas, including the Value-Added Producer Grant (VAPG) program. This report examines the impacts of the VAPG program on business survival and growth. The VAPG program provides financial assistance for agricultural producers to enter into value-added activities related to processing and/or marketing of value-added products. The study was conducted by combining data on the VAPG program obtained from RD with establishment-level data from the National Establishment Time-Series (NETS), and comparing business survival and employment growth outcomes of VAPG recipients to the outcomes of businesses having similar observable characteristics and employment growth histories that did not receive VAPGs. The results show that VAPGs enable recipient businesses to reduce the risk of failing and to provide more jobs than the comparison group.
Temperature dependence of spatially heterogeneous dynamics in a model of viscous silica

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Molecular dynamics simulations are performed to study spatially heterogeneous dynamics in a model of viscous silica above and below the critical temperature of the mode coupling theory, $T_{MCT}$. Specifically, we follow the evolution of the dynamic heterogeneity as the temperature dependence of the transport coefficients shows a crossover from non-Arrhenius to Arrhenius behavior when the melt is cooled. It is demonstrated that, on intermediate time scales, a small fraction of oxygen and silicon atoms are more mobile than expected from a Gaussian approximation. These highly mobile particles form transient clusters larger than that resulting from random statistics, indicating that dynamics are spatially heterogeneous. An analysis of the clusters reveals that the mean cluster size is maximum at times intermediate between ballistic and diffusive motion, and the maximum size increases with decreasing temperature. In particular, the growth of the clusters continues when the transport coefficients follow an Arrhenius law. These findings imply that the structural relaxation in silica cannot be understood as a statistical bond breaking process. Though the mean cluster sizes for silica are at the lower end of the spectrum of values reported in the literature, we find that spatially heterogeneous dynamics in strong and fragile glass formers are similar on a qualitative level. However, different from results for fragile liquids, we show that correlated particle motion along quasi one-dimensional, string-like paths is of little importance for the structural relaxation in this model of silica, suggesting that string-like motion is suppressed by the presence of covalent bonds.

description: A number of prosthetic materials, it may be used to replace facial parts of maxillofacial that lost through disease or trauma. The silicone rubbers it is considered are thebest materials in this area. So that, the aim of this research is to study the effect of addition of PMMA material on the mechanical properties of blends SR/PMMA at different loading level (5%, 10%, 15% and 20%) of PMMA to silicone rubber. FTIR test and some mechanical properties such as tensile strength, elastic modulus, elongation percentage, hardness, compression strength and roughness were done on the all prepared samples, which are used for maxillofacial prostheses applications. The results showed that the optimum percent of PMMA is 10% that has ideal characteristic. So, this sample may be a promising material to achieve the properties required for maxillofacial prosthetic applications.

description: We demonstrate that the QCD topological susceptibility nonperturbatively gets a significant contribution signaled by flavor-nonuniversal quark condensates at around the pseudo-critical temperature of the chiral crossover. It implies a remarkable flavor breaking in the axial anomaly as well as the QCD theta vacuum in high temperature QCD, which are almost flavor universal in the vacuum. A nontrivial flavor breaking is triggered by nonperturbative thermal loop corrections at around the chiral crossover, which is different from the trivial flavor violation just scaled by the quark mass ratio, observed at asymptotically high temperatures. This critical flavor violation cannot be dictated by the chiral perturbation theory with that lattice QCD usually compares, or the dilute instanton gas approximation based on that its astrophysical implications have conventionally been made. This would give an impact on the thermal history and the cosmological evolution of QCD axion including the estimate of the relic abundance as a dark matter candidate.

description: Chinese companies are increasing their investments in foreign agricultural and food assets. Their broad aims are to gain profits for Chinese investors while achieving national food security and projecting China’s influence abroad. While the United States is the largest supplier of China’s agricultural imports, it has not been a major target of Chinese agricultural investment. Chinese investors tend to enter less-developed countries where there are few competitors, potential to raise productivity using Chinese technology, and potential to diversify suppliers of Chinese imports. A few companies with access to financing from Chinese banks are pursuing mergers, acquisitions, and partnerships with companies in more developed markets. These investments reflect changes in China’s demand for food and its need for upgrades in technology and management, but most ventures have modest impacts on agricultural trade.

AN APPRAISAL OF THE ROLE OF CREATIVITY IN WHITEHEAD'S METAPHYSICS
Creators: name: Singh, Ravi Prakash
Publisher: name: American University
Year: 2023

description: Whitehead places "Creativity" under the category of the ultimate notions in his work Process and Reality. It is the fundamental activity underlying every act of creation. Actual entities or actual occasions, which are the metaphysical realities in Whitehead's system, are the products of the universal Creativity. The phrase "the products of the universal Creativity" does not mean that Creativity is some external agency which causes the creation of actual entities; it is, rather, inherent in the actual entities by virtue of which they are called self-creative. Apart from actual entities, Creativity is merely an abstraction. Creativity is the basic energy for the creation of actual entities, but it is incapable of providing any forms for them, without which entities are indeterminate. For definite forms, actual entities have to depend on a different kind of entities which Whitehead calls "eternal objects." Which form will be selected by a particular actual entity depends on the purpose and value it has for that entity. The entity which determines the purpose and value of eternal objects and serves as their abode is an eternal actual entity which Whitehead calls "God." God evaluates eternal objects and displays them to actual entities. Actual entities, initially, get attracted to these forms presented by God. This initial attraction constitutes the initial aim of actual entities, which is provided by God. Thus, the creation of an actual entity not only needs Creativity, but also eternal objects and God. Keeping in view the contributions of eternal objects and God, the "ultimacy" of Creativity in Whitehead's metaphysical system becomes questionable. In order to be "ultimate," Creativity must account for the creation of the world independently. But, as said earlier, it cannot do so without the help of other formative elements, i.e., eternal objects and God. Hence, in a coherent system like Whitehead's, the idea of an "ultimate" does not fit well.

description: Exoplanet discoveries have demonstrated a vast range of planetary system architectures. The demographic of compact planetary systems are especially interesting from the perspective of planetary formation and the evolution of orbital dynamics. Another interesting demographic is that of giant planets in eccentric orbits, since these planets have likely had a dynamical history involving planet-planet scattering events. The WASP-47 system is particularly fascinating since it combines these two demographics, having both compact planetary orbits and a giant planet on an eccentric orbit within the system Habitable Zone. Here we provide an analysis of the WASP-47 system from the perspective of atmospheric detection and characterization. We discuss the system architecture and the potential for additional long-period planets. We simulate expected phase variations as a function of planet orbital phase for the system due to the combined effect of the planets. We present analysis of precision photometry of WASP-47 from the K2 mission, phased on each of the planets. The analysis rules out the detection of phase signatures for the two inner-most planets, enabling constraints upon their albedos and atmospheric properties. Our study concludes that WASP-47b is an example of a "dark" planet with a tentative geometric albedo of 0.016 and a 1$σ$ upper limit of 0.17. The WASP-47e data are consistent with a broad range of albedos, but also show early evidence of having a relatively low albedo. The growing number of dark, short-period giant planets provide the framework of an ideal sample for studying low albedo dependence on atmospheric composition.

description: We analyse the impact of the Russian food embargo on European and Russian trade patterns using a triple-difference estimation strategy. We quantify the effects on the value of trade, the trade price of products covered by the ban, and the new trade flows generated by the ban. Our results point to an average e 125 million loss in monthly EU28 exports to Russia due to the ban (with Lithuania, Poland, and Germany bearing the largest losses). However, only 45% of the drop in EU28 exports of banned products to Russia would be due to the ban. In addition, EU products banned from the Russian market were sold elsewhere at lower prices. The reorientation of EU exports to other markets translated into selling larger amounts to old trade partners, as well as in accessing new markets. EU member states were unevenly affected by the ban. Germany and Poland compensated their large losses on the Russian market by a strong increase in exports to other trade partners (mostly intra-EU), at the expense of other EU acountries, such as France and Denmark.

description: Some potent criticisms have been leveled against the legal-adversarial method of resolving divorce disputes, especially by proponents of divorce mediation. Nevertheless, there is a paucity of empirical data on the validity and reliability of the divorce mediation model. In Study 1 of the present investigation, subjects seeking a mediated resolution of their divorce disputes were compared to subjects about to begin the legal adversarial process with respect to level of marital conflict. The two groups were found to be roughly equivalent in overall marital maladjustment, based on Dyadic Adjustment Scale scores. Initial differences between mediated and nonmediated couples in level of marital conflict appear to be minimal. Study 2 examined matched groups of mediated and nonmediated individuals 6 to 18 months after their separation agreement was signed. Those individuals who utilized mediation to reach their agreements were found to be significantly more satisfied, more amicable toward the ex-spouse, and more able to effectively communicate with him or her than their adversarial counterparts. A mediated resolution was found to cost significantly less, on the average, than a settlement achieved through the adversarial process. Present results also show a difference in type of custody arrangement produced in mediation and the adversary system. Significantly more mediated subjects opted for joint custody. The two groups were similar in consistency of support payments and in overall psychological adjustment. On the basis of the findings from Study 1, it is argued that these effects observed in Study 2 are unlikely to be due to differences in the premediation characteristics of couples. The findings are discussed in relation to previous research, and alternative explanations for the observed differences are explored. Present results suggest that mediation is related to some identifiable differences in behavior and attitude among those who seek marital separation and divorce.

description: The concept of intellectual property and the protections granted under intellectual property law in today’s globalised world have largely followed a Western view of intellectual property rights. Prior to colonisation or the introduction of Western legal systems in many parts of the world, indigenous communities engaged in intellectual creativity and devised their own mediums for protecting their intellectual creations under customary law. Concerns about the piracy of the intellectual creations of traditional communities the world over have projected the issue of protecting traditional knowledge into the international arena. This article explores the possibility of protecting the traditional knowledge of traditional communities under international regimes like the WTO’s Agreement on Trade Related Aspects of Intellectual Property Rights and the Convention on Biological Diversity. The discussion also explores the use of domestic law to protect traditional knowledge from piracy.
ITALIAN COMMUNIST PERCEPTIONS OF SOVIET FOREIGN POLICY
Creators: name: Baker, John Alexander
Publisher: name: American University
Year: 2023

description: The study addressed two problems relating to the Italian Communist Party's (PCI) perceptions of Soviet foreign policy. It examined them in the context of the party's domestic political strategy and its ongoing process of deradicalization (Part I). The first problem was to analyze (Part II) the PCI's evolving (1979-82) global critique of Soviet foreign policy as Soviet acts or threats of force negatively affected the international context for PCI strategy. The second problem was to examine (Part III) the relationship between the foreign affairs elite's sense of nearness to power and the persistence of its critique of Soviet foreign policy. The research methodology for the first problem consisted of detailed examination of key documents and articles indicated by PCI sources as especially significant; thorough search of the PCI press for 1979-82; and a review of analyses done by Italian, American, German, British, and French scholars. Interviews with thirty PCI officials in early 1985 provided the research material for the second problem with the focus on ten individuals selected for current full time foreign affairs responsibility. The interview schedule covered attitudes toward domestic strategy, priorities in Western Europe, and perceptions of Soviet policy. The documentary research showed the official PCI critique of Soviet foreign policy becoming global, rather than episodic, in 1980-81. The PCI blamed for Soviets for taking advantage of the US "Vietnam syndrome" after 1975 and contributing to the deterioration of detente. Despite their expectation in 1985 of remaining in an opposition role domestically, the interview sample continued to support the apportionment of responsibility to the USSR for the deterioration of detente expressed in the global critique and to favor an orientation toward the European left rather than Moscow. The foreign affairs elite's commitment to the party's critique was further confirmed by its disinclination to open up the party's decision-making process too broadly, evidently aware that the critique of Soviet foreign policy had been imposed from above by forceful party leadership. The majority of its members had become, as foreign affairs elites frequently do, guardians of acquired perceptions but uncertain as to the solidity of the constituency behind them.

description: Consumers have access to a variety of sources of nutrition information, including the Nutrition Facts label on packaged foods, USDA’s MyPlate food guidance for healthy eating, and the posting of nutrition information in restaurants. This study uses unique data from USDA’s 2012-13 National Household Food Acquisition and Purchase Survey (FoodAPS) to explore the correlation between consumers’ use of nutrition information and the healthfulness of their food choices. Healthfulness of food purchases is assessed by conformance with the Dietary Guidelines for Americans as measured by the 2010 Healthy Eating Index (HEI-2010). Results show that the HEI-2010 score is positively associated with nutrition information use. This positive correlation between nutrition information use and HEI-2010 also holds within each of the three categories of household participation in USDA’s Supplemental Nutrition Assistance Program (participant, low-income nonparticipant, and high-income nonparticipant). Examining the influence of nutrition information use separately on food-at-home and food-away-from-home purchases shows that the food-at-home HEI-2010 score is positively correlated with more nutrition information use while the food-away-from-home HEI-2010 score is not correlated with more nutrition information use.

description: Many face organs are exposed to different environmental conditions in terms of different of ambient temperature, degradation, discoloration, changes in humidity and especially frequent washing of these organs. These conditions cause changes in the structure of materials so, for restoring the function and improving aesthetics of the affected areas of maxillofacial by surgical reconstruction and prosthetic rehabilitation the silicone rubbers (SR) and PMMA are the materials of choice. So that, the aim of this research is to investigate the effect of addition of polymethyl methacrylate (PMMA) material on the physical properties of blends from SR/PMMA at different weight percentage (5%, 10%, 15% and 20%) of PMMA to silicone rubber. Fourier transform infrared spectrometer test ) FTIR(, density, water absorption and thermal properties were done on the all prepared samples, which are used for maxillofacial prostheses applications. The results showed thatthere is good correlation in FTIR spectrum for reference silicone rubber and (SR/PMMA) polymer blend and this confer a good compatibility between silicone rubber matrix material and PMMA. As well as the physical properties showed that the favorite percent of PMMA is 10% which has ideal characteristic. So, this sample may be a suitable material to achieve the properties required for maxillofacial prosthetic applications.

description: We define on-shell symmetries and characterize them for Lagrangian systems. The terms appearing in the variation of the Poincare'-Cartan form, which vanish because of field equations, are found to be strongly constrained if the space of solutions has to be preserved. The behaviour with respect to solution dragging is also investigated in order to discuss relations with the theory of internal symmetries of a PDE.

description: Two antiferromagnetically coupled tunneling systems is a minimal model exhibiting the effect of quantum-mechanical phase in the Landau-Zener effect. It is shown that the averaged staying probability oscillates vs resonance shift between the two particles, as well as vs sweeping rate. Such a resonance shift can be produced in Mn-4 dimers by the gradient of the magnetic field.

description: Doubtless Brexit is one of the most important regulatory challenges for an entire country since the beginning of the twenty-first century. Equally important are the implications, in terms of costs and benefits, of this democratic decision for the UK’s economy and for its regulatory environment. So far, some cost-benefit analyses have attempted to measure the post-Brexit situation. Few studies have proposed a ‘meta cost-benefit analysis’, which would encompass current studies into one aggregated study. No study has provided for a meta cost-benefit analysis as the Brexit negotiations unfold and which provides for a comprehensive discussion of the regulatory issues at stake. This article intends to fill this gap. The originality of this article lies in both its content and its timing. The content is original because it discusses the scientific possibility of a meta cost-benefit analysis of Brexit together with the inherent limits associated with such an endeavour. The timing is appropriate as we are in the critical halfway point of the two-year negotiation period (2017-2019) during which the EU and the UK must secure the relevant deals to ensure a smooth and frictionless Brexit for both sides of the Channel.

description: We have obtained deep Hubble Space Telescope (HST) imaging of four faint and ultra-faint dwarf galaxy candidates in the vicinity of M101 - Dw21, Dw22, Dw23 and Dw35, originally discovered by Bennet et al. (2017). Previous distance estimates using the surface brightness fluctuation technique have suggested that these four dwarf candidates are the only remaining viable M101 satellites identified in ground based imaging out to the virial radius of M101 (D~250 kpc). Advanced Camera for Surveys imaging of all four dwarf candidates shows no associated resolved stellar populations, indicating that they are thus background galaxies. We confirm this by generating simulated HST color magnitude diagrams of similar brightness dwarfs at the distance of M101. Our targets would have displayed clear, resolved red giant branches with dozens of stars if they had been associated with M101. With this information, we construct a satellite luminosity function for M101, which is 90% complete to M_V=-7.7 mag and 50% complete to M_V=-7.4 mag, that extends into the ultra-faint dwarf galaxy regime. The M101 system is remarkably poor in satellites in comparison to the Milky Way and M31, with only eight satellites down to an absolute magnitude of M_V=-7.7 mag, compared to the 14 and 26 seen in the Milky Way and M31, respectively. Further observations of Milky Way analogs are needed to understand the halo-to-halo scatter in their faint satellite systems, and connect them with expectations from cosmological simulations.

Fourth-order Coronagraph for High-Contrast Imaging of Exoplanets with Off-axis Segmented Telescopes

description: We propose a coronagraphic system with fourth-order null for off-axis segmented telescopes, which is sufficiently insensitive to the telescope pointing errors and finite angular diameter of the host star to enable high-contrast imaging of potentially habitable planets. The inner working angle of the coronagraphic system is close to $1λ/D$, and there is no outer limit. The proposed coronagraphic system is made up of a new focal plane mask and an optimized Lyot stop with the second-order null. The new focal plane mask is an extension of the band-limited masks with a phase modulation. We construct a coronagraphic system with fourth-order null by placing two of the new coronagraph systems in succession to be orthogonal to each other. The proposed system is limited to narrow-band usage. The characteristics of the proposed coronagraph system are derived analytically, which includes: (1)the leak of stellar lights due to finite stellar diameter and pointing jitter of a telescope, and (2)the peak throughput. We achieve the performance simulations of this coronagraphic system based on these analytical expressions, considering a monochromatic light of 0.75$\mathrmμ$m and off-axis primary mirror with a diameter of 8.5m. Thanks to the wide working area of the mask, the result shows that terrestrial planets orbiting K and G-dwarfs can be detected under the condition that the telescope pointing jitter is less than $0.01λ/D\approx240$as. The proposed coronagraphic system is promising for detection of potentially habitable planets with future space off-axis hexagonally segmented telescopes.
