description: Supplying food to a growing population has always been a concern for authorities in Iran. In this regard, agricultural sector plays an important role in food supply and food’s security by increasing agricultural production. But the most important concern in Iranian agricultural sector are the scarcity and resource constraints. Therefore, it seems that only way to increase food supply along with food security purpose is to increase productivity. One of the policy used to increase productivity is the output price policy, in particular for those strategic products that provided Iran's political security. The aim of this paper is to assess the effect of output price policy for Iranian agriculture. This latter is represented by a regional agricultural model, based on PMP, that groups the agriculture supply of 30 Iranian regions. The assessment of IAP presented in this paper confirms the biggest effects regions. It means that the effect of new IAP scenario is different in each region and each region has special cropping pattern. In this regard, policy makers should implement different sustaining policies at regional level. Also, if Iran wants to join WTO, it should be reduced or removed the amount of payments for inefficient crops.

description: This paper reveals some new and rich dynamics of a two-dimensional prey-predator system and to anticontrol the extinction of one of the species. For a particular value of the bifurcation parameter, one of the system variable dynamics is going to extinct, while another remains chaotic. To prevent the extinction, a simple anticontrol algorithm is applied so that the system orbits can escape from the vanishing trap. As the bifurcation parameter increases, the system presents quasiperiodic, stable, chaotic and also hyperchaotic orbits. Some of the chaotic attractors are Kaplan-Yorke type, in the sense that the sum of its Lyapunov exponents is positive. Also, atypically for undriven discrete systems, it is numerically found that, for some small parameter ranges, the system seemingly presents strange nonchaotic attractors. It is shown both analytically and by numerical simulations that the original system and the anticontrolled system undergo several Neimark-Sacker bifurcations. Beside the classical numerical tools for analyzing chaotic systems, such as phase portraits, time series and power spectral density, the 0-1 test is used to differentiate regular attractors from chaotic attractors.

title: Studies on the Development of Intestinal Secretory Immunity to Colibacillosis in the Piglet.
Creators: name: Allen, William Dennis
Publisher: name: The Open University
Year: 1981

description: The interaction between the cellular components of the intestinal mucosa and its lumenal environment has been studied in the piglet with the objective of establishing an early onset of secretory antibodies against pathogenic E. coli. Morphological evaluation of the mucosal architecture during development showed that inflammatory changes occur in apparently healthy suckling piglets as early as 10 days after birth. These changes, which become progressively more severe as the animal ages, are greatly exacerbated by E. coli infection. The proximal small bowel is the area most affected, indicating that protective immune function should be preferentially directed towards this region. A quantitative evaluation of macromolecular absorption at different levels of small intestine, using both horse-radish peroxidase and E. coli endotoxin indicated that uptake was greatest in the anterior small bowel and that the rate of absorption decreased with age. Uptake of one macromolecule was not affected by the presence of the other suggesting lack of competition for binding sites on the absorptive epithelium. Immunofluorescent studies on intestinal mucosa of pigs of varying age demonstrated IgM containing cells in duodenal lamina propria of 2 day old animals. IgM cells continued to out number IgA and IgG cells until the animals were weaned at 3 weeks old, thereafter IgA cells predominated. In vitro evaluation of intestinal secretory antibody production in response to oral immunization showed specific antibodies in 14 day old pigs immunized from 4 days old. The greatest response was obtained from the anterior small bowel, again emphasising the importance of this region. The protection conferred by early oral vaccination was determined, in vivo, in piglets experimentally infected with enteropathogenic E. coli and weaned at 14 days of age. The faecal E. coli count of the vaccinated group was reduced 100 fold compared to the placebo group and their weight gain after 1 week was 15% greater. The implications of these findings are discussed.

description: We put forward a finite theory of quantum scattering of fundamental particles without using auxiliary particles. It suggests that to avoid ultraviolet divergencies and model faster-than-light effects it suffices to appropriately change only the free-field Lagrangians while retaining their locality in space-time and Lorentz invariance. Using functions of two independent four-vector variables, we base this finite theory on the path-integral formalism on the four-dimensional space-time and the Lehmann-Symanzik-Zimmermann reduction formula.

description: A group of medical laboratory technicians has been surveyed in order to determine ways in which the effectiveness of the existing arrangements and provisions for their education and training may be improved. Information and opinion was obtained by questionnaire. The survey population comprised all students attending courses in medical laboratory sciences at a regional college of technology during the academic year 1975 - 76. The data obtained provides a portrait of the existing situation pertinent to the education and training of medical laboratory technicians. The major characteristics of the survey subjects, the factors which influenced their entry to the career and their membership of the professional body, the arrangements and provisions made for their academic study, and laboratory training and their opinions of these processes, and the perceived and desired interrelationship of college study and laboratory training, are described. Analysis has been made of the influence of certain independant variables upon the provisions made for study and for training and upon students® opinions of the quality of these provisions. Arrangements and provisions for college study are found to be well- established. The extent to which students were satisfied with study arrangements and facilities is shown to be significantly dependant upon their mode of college attendance. There is evidence of room for improvement in several aspects of college study provision. Laboratory training is shown to operate on a relatively casual basis. The amount of training provided and the manner of its provision is seen to be significantly dependant upon the type of course which students attended and upon the institution in which they were trained. There is evidence of room for improvement in the content, provision and regulation of laboratory training.

Magnetostriction in magnetic gels and elastomers as a function of the internal structure and particle distribution

description: Magnetic gels and elastomers are promising candidates to construct reversibly excitable soft actuators, triggered from outside by magnetic fields. These magnetic fields induce or alter the magnetic interactions between discrete rigid particles embedded in a soft elastic polymeric matrix, leading to overall deformations. It is a major challenge in theory to correctly predict from the discrete particle configuration the type of deformation resulting for a finite-sized system. Considering an elastic sphere, we here present such an approach. The method is in principle exact, at least within the framework of linear elasticity theory and for large enough interparticle distances. Different particle arrangements are considered. We find, for instance, that regular simple cubic configurations show elongation of the sphere along the magnetization if oriented along a face or space diagonal of the cubic unit cell. Contrariwise, with the magnetization along the edge of the cubic unit cell, they contract. The opposite is true in this geometry for body- and face-centered configurations. Remarkably, for the latter configurations but the magnetization along a face or space diagonal of the unit cell, contraction was observed to revert to expansion with decreasing Poisson ratio of the elastic material. Randomized configurations were considered as well. They show a tendency of elongating the sphere along the magnetization, which is more pronounced for compressible systems. Our results can be tested against actual experiments for spherical samples. Moreover, our approach shall support the search of optimal particle distributions for a maximized effect of actuation.

description: We established a production method of a good millimeter-wave absorber by using a 3D-printed mold. The mold has a periodic pyramid shape, and an absorptive material is filled into the mold. This shape reduces the surface reflection. The 3D-printed mold is made from a transparent material in the millimeter-wave range. Therefore, unmolding is not necessary. A significant benefit of this production method is easy prototyping with various shapes and various absorptive materials. We produced a test model and used a two-component epoxy encapsulant as the absorptive material. The test model achieved a low reflectance: $\sim 1\%$ at 100 GHz. The absorber is sometimes maintained at a low temperature condition for cases in which superconducting detectors are used. Therefore, cryogenic performance is required in terms of a mechanical strength for the thermal cycles, an adhesive strength, and a sufficient thermal conductivity. We confirmed the test-model strength by immersing the model into a liquid-nitrogen bath.

Complex lithium ion dynamics in simulated LiPO3 glass studied by means of multi-time correlation functions
Creators: name: Vogel, Michael
Publisher: name: arXiv
Year: 2003
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: Molecular dynamics simulations are performed to study the lithium jumps in LiPO3 glass. In particular, we calculate higher-order correlation functions that probe the positions of single lithium ions at several times. Three-time correlation functions show that the non-exponential relaxation of the lithium ions results from both correlated back-and-forth jumps and the existence of dynamical heterogeneities, i.e., the presence of a broad distribution of jump rates. A quantitative analysis yields that the contribution of the dynamical heterogeneities to the non-exponential depopulation of the lithium sites increases upon cooling. Further, correlated back-and-forth jumps between neighboring sites are observed for the fast ions of the distribution, but not for the slow ions and, hence, the back-jump probability depends on the dynamical state. Four-time correlation functions indicate that an exchange between fast and slow ions takes place on the timescale of the jumps themselves, i.e., the dynamical heterogeneities are short-lived. Hence, sites featuring fast and slow lithium dynamics, respectively, are intimately mixed. In addition, a backward correlation beyond the first neighbor shell for highly mobile ions and the presence of long-range dynamical heterogeneities suggest that fast ion migration occurs along preferential pathways in the glassy matrix. In the melt, we find no evidence for correlated back-and-forth motions and dynamical heterogeneities on the length scale of the next-neighbor distance.

description: The present paper has examined the welfare implications of safety and quality policy changes among beef consumers in Southern Ghana. The empirical results revealed profound heterogeneity in preferences for food safety and quality attributes at individual and segment levels. Four distinct consumer segments were revealed using a latent class model. We show that besides traditional socioeconomic factors; trust, competence and confidence in actors along food safety chain significantly impact on preferences for different food safety and quality policy attributes. Compensating surplus estimates reveal that welfare improvement arising from food safety and quality policy changes varies from one class to another. The findings show evidence of imperative segmental equity issues in food safety and quality policies. The welfare estimates indicate that evaluating willingness to pay values alone is not enough. The paper suggests that future research and policy decisions on food safety and quality changes take into account the segment of consumers whose welfare can potentially be improved or reduced due to the policy changes. Insights from this study are expected to assist policymakers in developing countries, especially in Africa to understand the welfare implications and effective food safety and quality measures Acknowledgement :

description: We show that large amplitude, coherent acoustic phonon wavepackets can be generated and detected in In$_x$Ga$_{1-x}$N/GaN epilayers and heterostructures in femtosecond pump-probe differential reflectivity experiments. The amplitude of the coherent phonon increases with increasing Indium fraction $x$ and unlike other coherent phonon oscillations, both \textit{amplitude} and \textit{period} are strong functions of the laser probe energy. The amplitude of the oscillation is substantially and almost instantaneously reduced when the wavepacket reaches a GaN-sapphire interface below the surface indicating that the phonon wavepackets are useful for imaging below the surface. A theoretical model is proposed which fits the experiments well and helps to deduce the strength of the phonon wavepackets. Our model shows that localized coherent phonon wavepackets are generated by the femtosecond pump laser in the epilayer near the surface. The wavepackets then propagate through a GaN layer changing the local index of refraction, primarily through the Franz-Keldysh effect, and as a result, modulate the reflectivity of the probe beam. Our model correctly predicts the experimental dependence on probe-wavelength as well as epilayer thickness.

Multi-criteria evolutionary algorithm optimization in horticulture crop management

Subjects: Environmental Economics and Policy

description: Climate variability requires adaptive production systems in agriculture often resulting in significant irreversible investments. Cultivar replacement programs in horticulture orchards that substitute older varieties for more heat- and drought-resilient varieties have enterprise values that are highly sensitive to the timing of such investments. Farm-level replacement programs are subject to multiple constraints around debt serviceability, operating costs, the replacement cycle and the rate of degradation of the existing orchard. The maximization of enterprise value subject to multiple constraints can be reduced to a multi-objective optimization problem. Over long horizons this optimization process generates a very-large solution space. Using a multi-objective evolutionary algorithm we examine uncertainties around climatic effects and the timing of investments for horticultural operations and derive the optimal times to adapt using cultivar replacement techniques. We find that naive switching decisions using traditional valuation methods are found to be suboptimal and can initiate poor decisions, potentially undermining adaptation efforts. We further show that opposing economic and climatic conditions can adversely impact enterprise value based on mistiming the investment decision. Application of the GA solver is demonstrated using a vector-based GIS to a farm where individual portions of an orchard are subject to varying rates of production, degradation and age.

Reconciling Returns to Education in Off-Farm Wage Employment among Women in Rural China

description: Previous studies have found that returns to education in off-farm wage employment in rural China are lower than estimates for other developing economies. This paper seek to understand why and to provide what we believe are more accurate estimates of the returns. The returns to education in rural China may have been systematically underestimated due to mismeasurements in wage rate and/or experiences. Using a nearly nationally representative dataset of female workers in rural China, with detailed information on hours worked and earnings (to calculate daily wage rate), and employment history (to more appropriately measure experiences), might help provide better estimates of returns to education. We find that estimates of returns to education, when employment interruptions are considered, are 3-4% higher than those without being considered. Moreover, we also find that mismeasurement in wage rate by not considering the hours worked cause even more serious underestimate of returns to education (by 25-43%). The paper demonstrates that, although some of the differences between our estimates and previous ones can be attributed to increasing returns since the 2000s, a larger portion of the differences are due to the nature of the data and the methodological approaches used by other authors.

description: The human-wildlife conflict of bird-window collisions accounts for an estimated 25 million annual bird deaths in Canada. This research report sets out to find out how this statistic is reflected at the University of British Columbia (UBC), in their Faculty of Arts Buchanan buildings. Evidence of bird-window collisions including feather smears, feather piles and carcasses, were searched for 4 days a week over a period of 64 days. At least 33 bird-window collisions occurred during this time period. Carcass persistence and searcher efficiency trials were conducted to help lower study bias. This paper examines why birds collide with windows, factors that increase collision rates, report results of the study, compares last years’ Buchanan study data of 49 collisions to this year’s data of 33 collisions to discuss varying factors, and find the facades that have the highest collision rates so that mitigation strategies can be applied. The effect of Feather Friendly © on façade 27 was investigated and found to be effective, decreasing bird window collisions by 90-100%. The recommended treatment is Feather Friendly © for façade 13 immediately and then 25 and 10 in the future. The results of this study can be used to lower the mortality rate of birds at the Buchanan buildings and hopefully shine a light on the urgency of UBC retrofitting their buildings to be more bird-friendly in design.

description: Phishing is a way of stealing people's sensitive information such as username, password and banking details by disguising as a legitimate entity (i.e. email, website). Anti-phishing education considered to be vital in strengthening "human", the weakest link in information security. Previous research in anti-phishing education focuses on improving educational interventions to better interact the end user. However, one can argue that existing anti-phishing educational interventions are limited in success due to their outdated teaching content incorporated. Furthermore, teaching outdated anti-phishing techniques might not help combat contemporary phishing attacks. Therefore, this research focuses on investigating the obfuscation techniques of phishing URLs used in anti-phishing education against the contemporary phishing attacks reported in PhishTank.com. Our results showed that URL obfuscation with IP address has become insignificant and it revealed two emerging URL obfuscation techniques, that attackers use lately, haven't been incorporated into existing anti-phishing educational interventions.

description: This paper assess the China s rural labor market by exploring the role of education playing in the wage premium among different job location by using samples covering more than 2000 households in 100 villages which are nationally representative. The results indicate that the rural labor markets are functioning and reflect as follows: (i) Whether the definitions of migration are, there are obvious wage premiums of migrants and with the boundary that we defined gradually away from the home township of rural labor, the wage premium becomes more obviously. At the same time, we find the return to education of migrants is significantly higher than those work locally. (ii) Compared to the labor force employed in his/her township, those who worked in other job locations all have a significant wage premium when we have a more comprehensive division after considering the employment distance and cost of living. (iii) Only work in the big cities has a consistent significantly higher return to education than work within labor s home township.

Especially, under a high compressive stress attained by 1 GPa pelletizing, the crystal size of a whisker was significantly enhanced up to 9.5 mm length (growth period: 96 h) which is 2.4 times larger than that of the conventional amorphous-precursors method. In addition, by using the stress-controlled precursors, the number of the obtained Bi-based whiskers were also increased by a factor of 1.8.

description: The purpose of this paper is to explore the impact of using computer to obtain information on the farm household s production and consumption, based on a field survey of farm households in northern China. The most important methods applied are instrumental variable (IV) method and propensity score matching (PSM). Estimators of IV, PSM and NNM(nearest neighborhood matching approaches are considered together to check the robustness of empirical results. This article carful impact evaluation results suggest that computer usages improves the size of arable land rented-in, but reduces family labor input intensity and the probability of selling agricultural outputs at farm-gate market. They also stimulated transportation, garment, housing and insurance expenditure per capita. First, we directly estimate computer usage impacts on a broader range of production and consumption indicators by including land-relative investments, variable investments, labor input and households expenditure and provide rigorous impact evaluations on the impact of access to computer. Second, we use IV method PSM method to correct self-selection bias, going beyond the single equation approach in other studies. This enables us to identify the causal relationship between computer usage and farmer s production and consumption decisions.

description: A modified shift-share analysis'for 1975-80 indicated that (1) 122,000 total net manufacturing jobs were lost to foreign trade; (2) automation accounted for about 1.8 million job losses; (3) apparel, leather, and motor vehicle industries lost many jobs to foreign trade; (4) the Great Lakes region lost many jobs to the South Atlantic, Southwest, and Far West regions; and (5) gains in nonmetropolitan areas were mainly in low-growth industries.
title: Some problems in rigorous equilibrium statistical mechanics
Creators: name: Rechtman, Raul Mauricio
Publisher: name: The Open University
Year: 1978

description: In this dissertation we deal with some problems of classical statistical mechanics. In chapter 1 we review the problem of the thermodynamic equivalence of ensembles for equilibrium ensembles of classical statistical mechanics. We show how the problem of the thermodynamic equivalence of ensembles is solved with the help of generalized Legendre transforms (defined in Appendix A). In chapter 2 we present some new results concerning the continuity of the thermodynamic limit temperature and the derivation of the Gibbs canonical distribution. For a classical system of interacting particles we prove, in the microcanonical ensemble formalism of statistical mechanics, that the thermodynamic limit inverse temperature, is a continuous function of the energy density. We also prove that the inverse temperature of a system approaches the thermodynamic limit inverse temperature as the volume of the system increases indefinitely. We also show that the probability distribution for a system of fixed size in thermal contact with a large system approaches the Gibbs canonical distribution as the size of the large system increases indefinitely, if the composite system is distributed microcanonically. In chapter 3 we present a review of the duplicate variable method as a simple and useful tool for proving correlation inequalities for the Ising ferromagnet and other lattice systems. Roughly speaking, the method consists in expressing a product of correlation functions as an expectation of a suitable function over a larger space. New variables are introduced through a transformation that is usually orthogonal, chosen in such a way that the correlation inequality we set to prove appears explicitly.

description: We analyse the inter-scale transfer of energy for two types of plane Poiseuille flow: the P4U exact coherent state of Park and Graham (2015) and turbulent flow in a minimal channel. For both flows, the dominant energy-producing modes are streamwise-constant streaks with a spanwise spacing of approximately 100 wall units. Since the viscous dissipation for these scales is not sufficient to balance production, the nonlinear terms redistribute the excess energy to other scales. Spanwise-constant scales (that is, Tollmien-Schlichting-like modes with zero spanwise wavenumber), in particular, account for a significant amount of net energy gain from the nonlinear terms. We compare the energy balance to predictions from resolvent analysis and we show that it does not model energy transfer well. Nevertheless, we find that the energy transferred from the streamwise-constant streaks can be predicted reasonably well by a Cess eddy viscosity profile. As such, eddy viscosity is an effective model for the nonlinear terms in resolvent analysis and explains good predictions for the most energetic streamwise-constant streaks. It also improves resolvent modes as a basis for structures whose streamwise lengths are greater than their spanwise widths by counteracting non-normality of the resolvent operator. Eddy viscosity does not respect the conservative nature of the nonlinear energy transfer which must sum to zero over all scales. It is less effective, consequently, for scales which receive energy from the nonlinear terms.

description: The public cost of reducing erosion in a west Tennessee watershed pilot program was 34 percent lower than the national average. The difference was attributed to the pilot program's emphasis on targeting specific erosion problems and to the establishment of permanent vegetative cover on highly eroding land. Even greater use of permanent vegetative cover, no-till cropping practices, and less reliance on cover improvement and terraces could reducd erosion in the area by an additional 32 percent with the same level of funds. A variable cost-sharing approach to erosion control may yield eyen bigger dividends in a targeting program.

description: This study examines the impact of the sharp rise in energy costs on employment in manufacturing. The slow rate of employment growth since 1973 was due mostly to the slow rate of growth in the general economy, rather than to high energy costs. On the other hand, the most energy-intensive industries averaged a decrease in employment in the 1974-78 period, while the less intensive ones averaged a small increase. Also, the most energy-intensive industries showed smaller increases in output than other industries, and higher product price increases. Nearly half the employment in the most energy-intensive industries is in nonmetro areas, about twice the proportion for all manufacturing.
title: The rise of copper wire, its manufacture and use to 1900: a case of industrial circumspection
Creators: name: Blake-Coleman, Barrie Charles
Publisher: name: The Open University
Year: 1981

description: This work critically examines the principal events and circumstances which influenced the course and rise of a crucial component in modern electrical technology - copper wire. This material, through successive eras, has played a variety of roles and enjoyed a range of distinct applications. In charting the development, manufacture and use of copper wire, the thesis describes how in its earlier history a traditionally made product, applied to traditional purposes (in arts and trades themselves subject to change) evolved into something which, in property and quality, was entirely different - electrical conductors. By 1850, copper wire can be said to have long begun its exchange of a traditional role for a modern one, having by this time found application as a telegraph conductor, with varying degrees of success. In this respect, early trials in overland and submarine telegraphy, as well as experiments on metallic conductors, are shown to have been major influences in the development of copper wire as an electrical conductor. Hence the transition of copper wire from its traditional qualities and roles to those where it was fit for specialist electrical applications, is fully considered. Careful consideration also is given to the work surrounding the establishment of electrical standards which came out of the need for improved copper conductors. Apart from the emphasis placed on reviewing those factors important in changing the quality and characteristics of traditional copper wire, an equal level of discussion is given over to considering the condition, growth and changing fortunes of the wire mills and the wire industry during its greatest period of change and expansion - 1750-1900. The pressures felt by the manufacturers during this time (technological, economic and, to some degree, social) are examined as too the state of the attitudes and policies, moulded by changing market demands and levels of prosperity. The overall object of the study is to give meaning and significance to, and a reasonable interpretation of, the historically important events which shaped the manufacture and application of copper wire. As such, the study critically assesses not only the reasons for the changing fortunes of copper wire, but the failure of the manufacturing effort behind it to emerge, at least by 1900, as a separate and distinct industry.
Nuclear spin diffusion in semiconductor nanostructures: Effects of inhomogeneous hyperfine interactions

description: We study the effect of contact hyperfine interaction on the nuclear spin diffusion coefficients in semiconductor quantum dots. The diffusion coefficients are calculated with both the method of moment and density matrix. We show that nuclear spin diffusion is strongly suppressed by the nonuniform hyperfine coupling resulting from the confined electron wavefunction. Our results agree with the observed suppression of nuclear spin diffusion in these structures in recent experiments, and clarify the degree of validity of the method of moment in an inhomogeneous system.

description: Population growth patterns and shifts in poultry production during the past 10 years caused major changes in the regional supply-consumption balances for poultry products. The South continues increasing its share of both broilers and turkeys. However, the southward movement of egg production peaked in 1979-80 and has now reversed itself, with rapid expansion in the East North Central region. More broiler and turkey meat but fewer eggs are being shipped between regions.
