Which news moves the euro area bond market?

This paper explores a long dataset (1999-2005) of intraday prices on German long-term bond futures and examines market responses to major macroeconomic announcements and ECB monetary policy releases. In general, adjustments in prices are quick and new information is usually incorporated into prices within five minutes of announcements. The volatility adjustment is more long-lasting than that in the conditional mean, and excess volatility can be observed up to 30 minutes after the releases. Overall, German bond markets tend to react more strongly to the surprise component in US macro releases compared to euro area and domestic releases, and the strength of those reactions to US releases has increased over the period considered. The paper also provides evidence that the outcome of German unemployment figures has been known to investors ahead of the prescheduled release.

An experiment was conducted to evaluate ammoniated corn husk in vitro digestibility in cattle ration. Measured parameters in the current experiment were in vitro digestibility of dry matter, organic matter, crude protein. This study was assigned into completely randomized design (CRD) with 5 treatments and 4 replications. The treatments were ; T0 = 70% Forage (100% grass + 0% ammoniation of Corn husk) + 30 % Concentrate, T1 = 70% Forage (75 % grass + 25% ammoniation of Corn husk) + 30 % Concentrate, T2 = 70% Forage (50% grass + 50% ammoniation of Corn husk) + 30 % Concentrate, T3 = 70% Forage (25% grass + 75% ammoniation of Corn husk) + 30 % Concentrate, T4 = 70% Forage (0% grass + 100% ammoniation of Corn husk) + 30 % Concentrate. Result of this study showed that the treatments were significantly (P<0,05) influence digestibility of dry matter, organic matter and crude protein. Increased level of ammoniated corned corn husk made higher in vitro digestibility of ration. It concluded that ammoniation of corn husk could increase digestibility and th eammoniated corn husk may substitute forage in cattle ration

Filtering and scalability in the ECO distributed event model

Event-based communication is useful in many application domains, ranging from small, centralised applications to large, distributed systems. Many different event models have been developed to address the requirements of different application domains. One such model is the ECO model which was designed to support distributed virtual world applications. Like many other event models, ECO has event filtering capabilities meant to improve scalability by decreasing network traffic in a distributed implementation. Our recent work in event-based systems has included building a fully distributed version of the ECO model, including event filtering capabilities. This paper describes the results of our evaluation of filters as a means of achieving increased scalability in the ECO model. The evaluation is empirical and real data gathered from an actual event-based system is used

Evaluasi Kecernaan in Sacco Beberapa Pakan Serat Yang Berasal Dari Limbah Pertanian Dengan Amoniasi

The aim of this study was to evaluate the effect ammoniated feed from agriculture by products on the in sacco dry matter, organic matter and crude protein digestibilities. This study was assigned into a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments were different types of low quality fibre of agricultural by-products found in Jambi Province; A = ammoniated rice straw with 6 % of urea and 15 % of inoculated rumen digesta, B = ammoniated palm oil fibre with 6% of urea and 15 % of inoculated rumen digesta, C = ammoniated corn peel with 6 % of urea and 15 % of inoculated rumen digesta, D = ammoniated top cane with 6 % of urea and 15 % of inoculated rumen digesta. Result of this study showed that the treatments were significantly affect (P<0,05) on the dry matter, organic matter and crude protein degradations. Ammoniation significantly increased degradation of feed compared with those without ammoniation. It is concluded that ammoniation with urea and addition of rumen digesta increased fibre quality of agricultural by-products. Different of type of ammoniated feed resulted in the difference respond on the nutrient degradation

An experiment was conducted to evaluate an improvement of corn peel with ammoniation in sacco digestibility in cow ration. Measured parameters in the current experiment were, in sacco degradation of dry matter, organic matter and crude protein. This study was assigned into completely randomized design (CRD) with 5 treatments and 4 replications. The treatments were ; R0 = 70% Forage (100% grass + 0% Corn Peel) + 30 % Concentrate, R1 = 70% Forage (75 % grass + 25% Corn Peel) + 30 % Concentrate, R2 = 70% Forage (50% grass + 50% Corn Peel) + 30 % Concentrate, R3 = 70%Forage (25% grass + 75% Corn Peel) + 30 % Concentrate, R4 = 70% Forage (0% grass + 100% Corn Peel) + 30 % Concentrate. Result of this study showed that the treatments were significantly (P<0,05) influence degradation of dry matter, organic matter and crude protein. The degradation after ammoniation significantly increased and were higher than that of without ammoniation. It is concluded that ammoniation with urea of corn peel could increase degradation and could be used asforage substitution in ration

Comparación de tecnologías de almacenamiento energético provenientes de energías renovables

Después de analizar la situación energética actual y las distintas formas de almacenar la energía, sobre todo la proveniente de energías renovables, añadido a las preocupaciones sobre el cambio climático global, la degradación medioambiental resultante del uso de los combustibles fósiles como fuente primaria de energía, junto con las inquietudes sobre la seguridad en el suministro energético, han llevado a muchos analistas a proponer al hidrógeno como portador universal de energía para el futuro. El uso del hidrógeno como vector energético permite el desarrollo de un amplio número de tecnologías. En concreto, las pilas de combustible alimentadas con hidrógeno pueden alcanzar eficiencias elevadas y presentan una gran variedad de posibles aplicaciones, tanto móviles como estacionarias. En el caso de que las líneas de desarrollo actuales lleguen a buen término, el hidrógeno y las pilas de combustible podrán contribuir de forma sustancial a alcanzar los objetivos clave de las políticas energéticas (seguridad de suministro, reducción de emisiones de CO2), especialmente en el sector transporte. Los resultados alcanzados en los últimos años en los programas de investigación, desarrollo y demostración han incrementado claramente el interés internacional sobre estas tecnologías, de las que se piensa que tienen el potencial de crear un cambio de paradigma energético, tanto en las aplicaciones de transporte como en las de generación distribuida de potencia. A largo plazo, la incorporación del hidrógeno como nuevo vector energético, ofrece un escenario en el que se podrá producir hidrógeno a partir de agua, con electricidad y calor de origen renovable, y será posible su utilización para atender a todo tipo de demandas, tanto las convencionales de la industria, en las que el hidrógeno juega un papel de reactivo en procesos diversos, como las energéticas en las que jugaría su nuevo papel de portador de energía. Las únicas emisiones que llevaría asociada la utilización del hidrógeno renovable serían óxidos de nitrógeno que se producirían en procesos de combustión. Sin embargo, su uso en pilas de combustible llevaría a emisiones nulas. Si la fuente del hidrógeno es el gas natural o el carbón, entonces será esencial la captura y almacenamiento del CO2 para lograr ahorros en emisiones, pero, en cualquier caso, los vehículos propulsados por pilas de combustible alimentadas con hidrógeno siempre reducirán las emisiones locales, dado que en el uso final el único efluente es vapor de agua. La visión de este sistema económico-energético del H2, se basa en la expectativa de que el hidrógeno pueda producirse a partir de recursos domésticos, de forma económica y medioambientalmente aceptable y en que las tecnologías de uso final del hidrógeno (pilas de combustible) ganen una cuota de mercado significativa. Los que en el mundo abogan por el hidrógeno indican que, si se alcanzan estas expectativas, una «economía del hidrógeno» beneficiará al mundo proporcionando una mayor seguridad energética porque se diversificarán las fuentes de energía, y una mayor calidad medioambiental porque se reducirán significativamente las emisiones locales y globale

Confidential execution of cloud services

In this paper, we present Confidential Domain of Execution (CDE), a mechanism for achieving confidential execution of software in an otherwise untrusted environment, e.g., at a Cloud Service Provider. This is achieved by using an isolated execution environment in which any communication with the outside untrusted world is forcibly encrypted by trusted hardware. The mechanism can be useful to overcome the challenging issues in guaranteeing confidential execution in virtualized infrastructures, including cloud computing and virtualized network functions, among other scenarios. Moreover, the proposed mechanism does not suffer from the performance drawbacks typical of other solutions proposed for secure computing, as highlighted by the presented novel validation results.
