Effect of Trade Liberalization in the Short-Grain Japonica Rice Market: A Spatial-Temporal Equilibrium analysis

Serious attention has always been bestowed on the stability of food markets. The government has acted on these issues through intervention on food prices that more or less creates distortion. These have been observed on U.S. and Japan. This paper develops a spatial-temporal equilibrium model for short-grain japonica trade and simulates policy alternatives for free trade and improved trade. It then discusses the results and its implications on the Philippine economy.demand

Causes and characteristics of uveitis in dogs

A uveíte é uma das afecções oculares mais frequente nos cães, muitas vezes associada a doença sistémica. O trabalho que se apresenta é um estudo retrospetivo de casos de uveítes caninas e foi realizado com o objetivo de fazer uma análise descritiva das uveítes nesta população e avaliar as suas causas, em especial a relação com doenças sistémicas

A New Sub-Period-Minimum Cataclysmic Variable With Partial Hydrogen Depletion And Evidence Of Spiral Disk Structure

We present time-resolved spectroscopy and photometry of CSS 120422:111127+571239 (=SBS 1108+574), a recently discovered SU UMa-type dwarf nova whose 55 minute orbital period is well below the cataclysmic variable (CV) period minimum of similar to 78 minutes. In contrast with most other known CVs, its spectrum features He I emission of comparable strength to the Balmer lines, implying a hydrogen abundance less than 0.1 of long-period CVs-but still at least 10 times higher than that in AM CVn stars. Together, the short orbital period and remarkable helium-to-hydrogen ratio suggest that mass transfer in CSS 120422 began near the end of the donor star's main-sequence lifetime, meaning that this CV is a strong candidate progenitor of an AM CVn system as described by Podsiadlowski et al. Moreover, a Doppler tomogram of the Ha line reveals two distinct regions of enhanced emission. While one is the result of the stream-disk impact, the other is probably attributable to spiral disk structure generated when material in the outer disk achieves a 2:1 orbital resonance with respect to the donor.NSF AST-1211196, AST-9987045Department of Physics at the University of Notre DameNSF Telescope System Instrumentation Program (TSIP)Ohio Board of RegentsOhio State University Office of ResearchAstronom

DIGITAL DIVIDE IN PHILIPPINE SCHOOLS

教育分野におけるICT の導入は，フィリピンの教育者たちの熱望によるものであり，アロヨ大統領や上院議員たちにも支持されており，2001年には，閣僚レベルでICT 形成と実行を司る管理組織を作り上げた．このような政策主導の下，2002年には学校カリキュラムにおけるコンピュータ活用とプログラミングの統合を狙った法案が上院レベルでも承認されてきた．本稿では，このような背景の下，オレタ上院議員が立ち上げた，全ての教育管理者のICT 利用を目指すTAO プロジェクトについて議論を行う

NKX2-1 Is Required in the Embryonic Septum for Cholinergic System Development, Learning, and Memory

The transcription factor NKX2-1 is best known for its role in the specification of subsets of cortical, striatal, and pallidal neurons. We demonstrate through genetic fate mapping and intersectional focal septal deletion that NKX2-1 is selectively required in the embryonic septal neuroepithelium for the development of cholinergic septohippocampal projection neurons and large subsets of basal forebrain cholinergic neurons. In the absence of NKX2-1, these neurons fail to develop, causing alterations in hippocampal theta rhythms and severe deficiencies in learning and memory. Our results demonstrate that learning and memory are dependent on NKX2-1 function in the embryonic septum and suggest that cognitive deficiencies that are sometimes associated with pathogenic mutations in NKX2-1 in humans may be a direct consequence of loss of NKX2-1 function

Rapid quantification of 4-ethylphenol in wine using high-performance liquid chromatography with a fluorimetric detector

A rapid method was established for quantifying 4-ethylphenol in wine using HPLC with a detector usually present in wine laboratories. It does not require sample preparation and carries out chromatographic separation in less than 5 min, making control of wine production processes easier. The method is linear up to 2000 μg·l-1 with RSD < 3 % over 20 μg·L-1 and gives a detection limit of 4.0 μg·L-1. It was validated in comparison with the HPLC-coulometric array detector, giving comparable results. Its application to the analysis of 720 DOC and table Italian red wines revealed that the 45 % of them had contents of 4-ethylphenol potentially affecting sensory perception of the aroma.

GENESI: Wireless sensor networks for structural monitoring

The GENESI project has the ambitious goal of bringing WSN technology to the level where it can provide the core of the next generation of systems for structural health monitoring that are long lasting, pervasive and totally distributed and autonomous. This goal requires embracing engineering and scientific challenges never successfully tackled before. Sensor nodes will be redesigned to overcome their current limitations, especially concerning energy storage and provisioning (we need devices with virtually infinite lifetime) and resilience to faults and interferences (for reliability and robustness). New software and protocols will be defined to fully take advantage of the new hardware, providing new paradigms for cross-layer interaction at all layers of the protocol stack and satisfying the requirements of a new concept of Quality of Service (QoS) that is application-driven, truly reflecting the end user perspective and expectations. The GENESI project will develop long lasting sensor nodes by combining cutting edge technologies for energy generation from the environment (energy harvesting) and green energy supply (small form factor fuel cells); GENESI will define models for energy harvesting, energy conservation in super-capacitors and supplemental energy availability through fuel cells, in addition to the design of new algorithms and protocols for dynamic allocation of sensing and communication tasks to the sensors. The project team will design communication protocols for large scale heterogeneous wireless sensor/actuator networks with energy-harvesting capabilities and define distributed mechanisms for context assessment and situation awareness. This paper presents an analysis of the GENESI system requirements in order to achieve the ambitious goals of the project. Extending from the requirements presented, the emergent system specification is discussed with respect to the selection and integration of relevant system components.The resulting integrated system will be evaluated and characterised to ensure that it is capable of satisfying the functional requirements of the projec

Resistance-based probabilistic design by order statistics for an oil and gas deep-water well casing string affected by wear during kick load

Deep-water wells for oil and gas extraction make structural components, such as casing and tubing, work in extremely harsh environmental conditions that accelerate component degradation and increase failure probability. Therefore, it is important to properly design casing strings under these operative circumstances (Baraldi et al., 2012)
