A DOUBLE-HURDLE MODEL OF FOOD DEMAND WITH ENDOGENOUS UNIT VALUES [PDF]

This study develops a unique double-hurdle model of demand for composite food commodities which endogenizes unit values. The model structure allows us to account for the inability to observe such values for non-purchasing households and simultaneously ...

A U‐shaped Microfluidic Platform for Culturing Vascularized Colorectal Cancer Spheroids Reveals Tumor–Endothelial Crosstalk and Invasion‐Associated Remodeling

Advanced Materials Technologies, EarlyView.
A closed U‐shaped microfluidic platform symmetrically embeds a single, size‐controlled HT29 colorectal cancer spheroid within a GFP‐HUVEC‐laden fibrin matrix. HT29 spheroids are associated with hyper‐branched endothelial network remodeling, while vascularized co‐culture is accompanied by anisotropic protrusive growth and EMT‐like marker changes in the ...

Communicating Ethical Arguments to Organic Consumers: A Study Across Five European Countries

International Journal on Food System Dynamics, 2011
 Additional ethical claims were tested with mock organic egg labels in five EU countries. The attitudes towards the advertising labels were assessed by multiple copy testing measures. A total of 156 individual responses were analysed.

3D Printed Photon Shield Assembly for Low‐Noise Visual Stimulation During Two‐Photon Imaging in Mice

Advanced Materials Technologies, EarlyView.
We present the Photon Shield, an open‐hardware system for low‐noise two‐photon calcium imaging during visual stimulation in mice. Combining a 3D‐printed headplate and rail‐mounted shield substantially reduces stray‐light contamination, as quantitatively verified. Functional validation confirms reliable cortical responses. Open design files enable broad

Analysing Consumer Responses to Food Safety Results of a Survey in the Netherlands [PDF]

Consumer confidence in food safety appears to be under pressure as a result of several food scandals and food scares in recent years. Regaining the trust of food consumers in food production and food products is talk of the town in both government ...

Chitin‐Chitosan Cryogels for the Reversible Sequestration and Recovery of Heavy Metals From Wastewater

Advanced Materials Technologies, EarlyView.
Chitin‐chitosan cryogels with degrees of N‐acetylation from 12.2% to 71.4% are fabricated by dissolution, coagulation and lyophilization for the sequestration of heavy metals from water. Colorimetry and differential pulse voltammetry showed controlled adsorption and desorption capacities for As5+, Co2+ and Cu2+, making this material attractive for ...

Public acceptance for genetic engineering techniques: the role of food values-based information

Scientific Reports
Genetic engineering techniques are emerging as crucial tools for addressing global food challenges. Consumer resistance however remains a major barrier to their adoption. This study explores whether framing genetical engineered foods around specific food

Extrusion‐Based Bioprinting of Living Bioinks for Tissue and Organ Engineering

Advanced Materials Technologies, EarlyView.
Extrusion‐based bioprinting is presented as the most versatile route for fabricating living, heterogeneous tissues. Its ability to combine diverse bioinks, support matrices, and advanced printhead geometries transforms familiar constraints into powerful biofabrication opportunities.
