Country of Origin Labeling of Fresh Produce: A Consumer Preference Analysis

This paper investigates the relationships between country of origin labeling (COOL) issues and consumers concern about safety and health towards using of foreign produce. Results show that those who were married, self employed, had higher incomes, or possessed more education were more likely to support COOL. A consumer survey showed that about 84% of respondents overall, and more specifically, about 84% of female and 83% of male respondents would like markets to provide information about country of origin of fresh produce. The result also shows that about 73% of respondents regularly read food advertisements in newspapers and grocery brochures.Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, International Relations/Trade,

Demographic Characteristics of Consumers who Read Grocery Brochures Regularly and Those who are willing to Switch Supermarkets to Buy Advertised Specials: An Analysis.

This study analyzed the influence of demographic and behavioral characteristics on the likelihood of a consumer to read food advertisements in grocery brochures and the likelihood of a consumer to shop at more than one store to purchase advertised specials. Overall, 73% and 46% of respondents read food advertisements and shop multiple stores to purchase advertised specials, respectively. Consumer characteristics which are shown to influence the reading of food advertisements and shopping at more than one food store to buy advertised specials were the possession of education beyond the 2/4 year college degree and the tendency to read ingredient labels.Consumer/Household Economics, Marketing,

Temperature dependent electrical resistivity of a single strand of ferromagnetic single crystalline nanowire

We have measured the electrical resistivity of a single strand of a ferromagnetic Ni nanowire of diameter 55 nm using a 4-probe method in the temperature range 3 K-300 K. The wire used is chemically pure and is a high quality oriented single crystalline sample in which the temperature independent residual resistivity is determined predominantly by surface scattering. Precise evaluation of the temperature dependent resistivity ($\rho$) allowed us to identify quantitatively the electron-phonon contribution (characterized by a Debye temperature $\theta_R$) as well as the spin-wave contribution which is significantly suppressed upon size reduction

Voltage-controlled inversion of tunnel magnetoresistance in epitaxial Nickel/Graphene/MgO/Cobalt junctions

We report on the fabrication and characterization of vertical spin-valve structures using a thick epitaxial MgO barrier as spacer layer and a graphene-passivated Ni film as bottom ferromagnetic electrode. The devices show robust and scalable tunnel magnetoresistance, with several changes of sign upon varying the applied bias voltage. These findings are explained by a model of phonon-assisted transport mechanisms that relies on the peculiarity of the band structure and spin density of states at the hybrid graphene|Ni interface

Selection criteria of test signals for correlation-based wire fault analysis (preprint)

ReportThis paper compares reflectometry signals for location of intermittent faults on live electrical cables. STDR, SSTDR, linear chirp, quadratic chirp, concave-up chirp, convex-down chirp and all frequency randomized phase noise signals were tested. The SSTDR was observed to be the most effective signal for live wire testing, because of its minimal interference with the existing signals and narrow correlation signature. This paper provides a methodology for systematically evaluating signal performance and design criteria for live wire test systems

An Operation Of Solar Authority Optimizer For DC Sharing System

This provides a high-efficiency solar system (SPO) which accurately harvests the maximum energy from the photovoltaic (PV) plate and then generates the energy to the DC micro-grid. The current model combines technologies integrated induction and transformer capacitor to achieve high voltage increase. The programmed system enhances the dynamics of the two-bridge, aggression and control algorithm tracking is extremely dynamic and puts the power to augment. Photovoltaic power is harvested and supplied to the Dual Active Bridge circuit where it can be elevated significantly using line conversion. The rotation rate of the selected switch is 4: 1 and this output is also supplied to the transformer bridge. The converter converts the current to the current point. This DC power is given as an input to the DC system. This method is very effective and stupid to conduct. The amount of material used to recreate it is lower than current systems

MHD Convection Flow of Kuvshinski Fluid past an Infinite Vertical Porous Plate with Radiation and Chemical Reaction Effects

An unsteady MHD free convective flow of a viscous incompressible visco-elastic fluid through a porous medium in the presence of radiation and chemical reaction effects are considered. The governing non-linear partial differential equations of the flow, heat and mass transfer are transformed into ordinary differential equations by using similarity transformations and then solved by two term perturbation technique. The effects of various flow parameters on velocity, temperature and concentration profiles as well as the skin-friction, Nusselt number and Shear wood number are discussed qualitatively and discussed graphically
