Dynamics of Price Transmission in the Presence of a Major Food Safety Shock: Impact of H5N1 Avian Influenza on the Turkish Poultry Sector

This article addresses the dynamic impact of the 2005 H5N1 avian influenza outbreak on the Turkish poultry sector. Contemporary time-series analyses with historical decomposition graphs are used to address differences in monthly price adjustments between market levels along the Turkish poultry supply channel. The empirical results show that price adjustments are asymmetric with respect to both speed and magnitude along the marketing channel. Results also reveal a differential impact of the exogenous shock on producers and retailers. The findings have critical efficiency and equity implications for the supply-chain participants.avian influenza, chicken, food safety shock, price transmission dynamics, supply chain, Turkey, Agribusiness, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, International Development, Livestock Production/Industries, Q11, Q13,

Evaluation of an automatic technique for counting unicellular organisms

The Coulter counter, originally designed for high-speed counting of blood cells, was used in this study for quantitative estimation of several species of unicellular algae. Tests of the instrument\u27s reliability and the reproducibility of its counts have given satisfactory results. The instrument is also well suited for use in the study of growth curves of unicellular algae. The instrument\u27s limitations and sources of error are discussed

The Impacts of Atlantic Bonito Rush and the Avian Influenza on Meat Products in Turkey

The Atlantic bonito rush experienced in Turkey in the Fall of 2005 coincides with the avian influenza food scare that happened exactly at the same time-period in the country. In this research using time-series techniques, we investigate how the food scare and the excess fish caught jointly influence the demand for meat products in Turkey.Food Consumption/Nutrition/Food Safety, Research Methods/ Statistical Methods,

Consumer responses to the H5N1 Avian Influenza: the case of Turkey

Using the case of the 2005-2006 Avian Influenza crisis also experienced in Turkey, we present its impacts on consumers' concerns on the pandemic. Based on our cross-sectional dataset derived from a household survey, results from our probit estimations imply that the negative impact of the pandemic on the poultry sector could have been alleviated by informing consumers about it. Frequent users, older consumers, and females are derived to be more concerned about the pandemic. Campaigns, especially through the efficient use of media channels, can target to minimize demand shocks and help poultry demand return to pre-outbreak levels. Using these results, policies can be designed to decrease the negative impacts of future food scares.

The impacts of Atlantic bonito rush and the avian influenza on meat products in Turkey

The Atlantic bonito rush experienced in Turkey in the Fall of 2005 coincided with the avian influenza food scare that happened exactly at the same time-period in the country. This study examines the reactions of Turkish retail prices to those events. In this research, using time-series techniques, we investigate how the food scare and the excess fish caught jointly influence the retail prices for beef, chicken, and fish products in Turkey. Historical decomposition of beef, chicken, and fish price series explains the behavior of prices in a neighborhood of the two events. The results showed that both fish and chicken prices fell initially due to those conflicting events, but beef and fish prices increased as more of these products were substituted for chicken.Atlantic bonito

Understanding Charge Transfer in Donor-Acceptor/Metal Systems: A Combined Theoretical and Experimental Study

We develop an effective potential approach for assessing the flow of charge within a two-dimensional donor-acceptor/metal network based on core-level shifts. To do so, we perform both density functional theory (DFT) calculations and x-ray photoemission spectroscopy (XPS) measurements of the core-level shifts for three different monolayers adsorbed on a Ag substrate. Specifically, we consider perfluorinated pentacene (PFP), copper phthalocyanine (CuPc) and their 1:1 mixture (PFP+CuPc) adsorbed on Ag(111).Comment: 12 pages, 10 figure

Magnetogravitational Vortex-Sheet Instability of Two Superposed Conducting Fluids in Porous Medium Under Strong Magnetic Field

The instability of two superposed homogeneous streaming uids is discussed under gravitational force and uniform magnetic eld in porous medium. The two streams are moving in opposite directions with equal velocities parallel to the horizontal plane. The solution has been obtained through the normal mode technique, and the most gen- eral dispersion relation has been obtained as 20th-order equation for the growth rate with quite complicated coe¢ cients. Solving numeri- caly the dispersion relation for appropriate boundary conditions with high Alfvén and sound velocities, it is found that uid velocities and porosity of porous medium have stabilizing e¤ects, and Alfvén and sound velocities have destabilizing e¤ects, while medium permeabil- ity has a slightly stabilizing e¤ect, and the dynamic viscosities have slightly destabilizing e¤ect. The limiting cases of non-porous medium have also been studied for both streaming and stationary uids.Key words: Hydrodynamic stability; Conducting uids; Flows through porous media; Gravitational force; Magnetohydrodynamic

Leukotrienes and leukotriene modifiers in pediatric allergic diseases

Leukotrienes are potent pro-inflammatory lipid mediators derived from arachidonic acid through several enzymatic pathways. They have an essential role in allergic inflammation, where they induce bronchoconstriction, airway edema, and chemotaxis of the inflammatory cells in the airways, nasal and conjunctival tissues. Leukotriene modifiers include leukotriene receptor antagonists (montelukast, zafirlukast and pranlukast) and leukotriene synthesis inhibitors (zileuton). These medications have been extensively used in childhood allergic diseases. This review will highlight the leukotriene pathway and its role in allergy as well as the effects of leukotriene modifiers in different allergic disorders
