Future Colliders

The high energy physics advantages, disadvantages and luminosity requirements of hadrons, of leptons and photon-photon colliders are considered. Technical arguments for increased energy in each type of machine are presented. Their relative size, and the implications of size on cost are discussed.Comment: LaTeX, 10 pages, 10figure

High Luminosity Muon Collider Design

Muon Colliders have unique technical and physics advantages and disadvantages when compared with both hadrons and electron machines. They should be regarded as complementary. Parameters are given of a 4 TeV high luminosity muon-muon collider, and of a 0.5 TeV demonstration machine. We discuss the various systems in such muon collider.Comment: LaTeX 5 pages 4 figure

A la recherche d’un visage pour une esquisse du législateur: le statut de “héritier” spécialement protégé (legitimario d’assistance) dans l’interprétation de la Cour Suprême de la Cuba

El artículo analiza el alcance de los herederos especialmente protegidos, los nuevos legitimarios asistenciales con los que dotó al Derecho de Sucesiones el Código Civil cubano. Las circunstancias que cualifican la condición de legitimario asistencial, son por regla general transitorias, como lo es la minoridad o como lo pueden ser ciertas discapacidades o la situación de dependencia o vulnerabilidad económica. Incluso personas con discapacidad intelectual severa o profunda, pueden depender económicamente de una persona y en un momento dado, cesar esa dependencia por disponer de un patrimonio que en el orden económico le permita tener cubiertas todas sus necesidades.This article discusses the extension of the “specially protected inheritors”: the newly created relief heirs that the Cuban Civil Code established as a part of the inheritance law. The circumstances that allow to qualify a person as a relief heir, are usually transitory, e.g. minority, special abilities and/or economic dependency or vulnerability. Even people with special abilities may depend financially on other person, and in any given moment, such dependence may be ended by having enough assets to cover all of his/her expenses and necessities.L’article traite de la portée des héritiers spécialement protégés, la nouvelle protection des héritiers dans le droit des successions du Code civil cubain. Les circonstances qui qualifient la situation de protection d’héritier, étaient généralement transitoires, comme minorité ou certains handicaps ou l’état de dépendance ou de vulnérabilité économique. Même les personnes ayant une déficience intellectuelle sévère ou profonde peut être financièrement dépendant d’une personne. Mais la dependence peut cesser, au le moment d’avoir des actifs dans l’ordre économique qui permettent couvrir tous ses besoins

Increasing U.S. Hard Red Winter Wheat Competitiveness in Latin American Markets

The United States wheat sector leadership in world markets is facing serious challenges. Canada, Australia, Argentina, the European Union (EU), and the Former Soviet Union (FSU) are growing contenders for international wheat markets. Wheat buyers´ concerns about quality specifications and its consistency have intensified without precedents in the last years. The study focuses on identifying the attributes that wheat buyers most value at the moment of purchase. The study will be done in two stages. The first stage will focus in estimating preferences from actual wheat transactions from different grain-sheds in the HRW growing area. The second stage will focus on the demand from Latin American millers and will estimate their attribute preference and elicit willingness to pay. The second stage will start with Mexican millers, given their importance for the HRW exports. A hedonic price model will be used for the first stage. The second part of the study will attempt to elicit miller´s preferences by using a self explicated approach. Expected results are that the "easy-to-measure attributes": test weight, and protein levels; and all functionality characteristics such as bake absorption, farinograph peak time, farinograph stability, alveograph p/l ratio will be the most valued by the wheat customers. We hypothesize that millers will be willing to pay a premium if those attributes are present in desirable levels. The information should provide insight into the efforts being made by wheat marketing agencies and the U.S. Wheat Associates to promote quality-based marketing of wheat to domestic and foreign millers. Discussion may also include the impacts of quality-based marketing on U.S. share of the world wheat market.International Relations/Trade,

Willingness-to-Pay for Attribute Level and Variability: The Case of Mexican Millers’ Demand for Hard Red Winter Wheat

In-person interviews were carried out with Mexican millers who were administered a conjoint-type survey designed to incorporate uncertainty in attribute levels. Two methods were used to model millers’ risk preferences: a modified mean-variance approach and an explicit expected utility approach. Controlling for variability, Mexican millers are willing to pay premiums for increases in quality factors such as test weight, protein content, falling number, and dough strength/extensibility. We find millers are not particularly sensitive to changes in the variability of quality characteristics. Out-of-sample forecasts suggest the mean-variance model provides an accurate depiction of actual Mexican imports.mean-variance, Mexican wheat market, moment generating function, preference elicitation, wheat quality, Agribusiness, Farm Management, Food Consumption/Nutrition/Food Safety, International Relations/Trade, Marketing, Production Economics, Risk and Uncertainty, C35, C42, Q13,

The effect of diatomaceous earth in live, attenuated infectious bronchitis vaccine, immune responses, and protection against challenge.

Live virus vaccines are commonly used in poultry production, particularly in broilers. Massive application and generation of a protective local mucosal and humoral immunity with no adverse effects is the main goal for this strategy. Live virus vaccines can be improved by adding adjuvants to boost mucosal innate and adaptive responses. In a previous study we showed that diatomaceous earth (DE) can be used as adjuvant in inactivated vaccines. The aim of this study was to test DE as adjuvant in an Ark-DPI live infectious bronchitis virus (IBV) vaccine after ocular or spray application. Titrating the virus alone or after addition of DE showed that DE had no detrimental effect on the vaccine virus. However, adding DE to the vaccine did not induce higher IgG titers in the serum and IgA titers in tears. It also did not affect the frequency of CD4+ T cells, CD8+ T cells and monocytes/macrophages in the blood and the spleen determined by flow cytometry. In addition, protection generated against IBV homologous challenges, measured by viral load in tears, respiratory signs and histopathology in tracheas, did not vary when DE was present in the vaccine formulation. Finally, we confirmed through our observations that Ark vaccines administered by hatchery spray cabinet elicit weaker immune responses and protection against an IBV homologous challenge compared to the same vaccine delivered via ocular route

Effect of Publicly Released Quality Information for US Hard Red Winter Wheat on Mexican Millers' Welfare

Entities have been providing quality related information to overseas wheat buyers as a response to the increased requests for this information. This study measures the value of information to Mexican millers. The value to Mexican millers is measured by the difference of the flour mill surplus and compensating variation.Agribusiness, Research and Development/Tech Change/Emerging Technologies,
