This paper aims to identify the key characteristics of model organisms that make them a specific type of model within the contemporary life sciences: in particular, we argue that the term “model organism” does not apply to all organisms used for the purposes of experimental research. We explore the differences between experimental and model organisms in terms of their material and epistemic fea...

“Nanomischief” is reviewed in hopes of helping our fellow “nanomachinists.” Scanning electron microscopy (SEM) and optical microscope images are shown, along with a short narrative of the problems encountered and their solutions.

Health care has increasing!y come to be understood as a commodity. The ethical implications of such an understanding are significant. The author argues that health care is not a commodity becanse health care (1) is non-proprietary, (2) serves the needs of persons who, as patients, are uniquely vulneräble, (3) essenfially involves a special human relationship which ought not be bought or sold, (...

In Gratzel’s cell, the electrons injected by the photo-excitation of dye molecules, anchored to a mesoporous TiO2 film, efficiently diffuse to the back contact achieving solar energy conversion at efficiencies exceeding 10%. The mesoporous TiO2 surface constituted of randomly arranged nanocrystallites with a roughness factor of the order 1000 is heavily populated with traps, defects and adsorbe...

In the nineteen eighties, a lot of ink was spent on the question of symbol grounding, largely triggered by Searle’s Chinese Room story (Searle,1980). Searle’s article had the advantage of stirring up discussion about when and how symbols could be about things in the world, whether intelligence involves representations or not, and what embodiment means and under what conditions cognition is embo...

background co-infection with human immunodeficiency virus (hiv) and hepatitis b virus (hbv) is common due to shared routes of transmission, as reported approximately 10% of 33 million hiv-infected patients worldwide are chronically infected with hbv. mutations of hbsag especially within the “a” determinant could alter the antigenicity of the protein, causing failure of hbsag neutralization and ...
