An Introduction to Microbial Metal Nanoparticle Preparation Method
Reduction of metal is an important defense mechanism in microorganisms as a way to manage metal toxicity. The inherent, clean, nontoxic and environmentally friendly ability of eukaryotic and prokaryotic microorganisms to form the metal nanoparticles is particularly important in the development of nanobiotechnology. New methods have been developed to control disparity, chemical composition, the size, and the shape to get the best particles which can be well applied in different fields of science. ...More »Have you read...
![[i][b]Figure 1: Proportion of the 39 canine subjects that Looked Away in response to an expression cue. [/b]The experiment was scored every two seconds for a period of ten seconds with a total of six scored intervals during which one of four postures was presented by a human experimenter to a canine subject, those being Avert Eyes, Grin, Yawn, and Stare Alone. A significant increase over time at a Bonferroni corrected level of p less than 0.0125 in the proportion of dogs that Looked Away in an interval was seen during the presentation of all but the Stare Alone posture.

Mind the Muzzle: Using Facial Expression as a Correlate of Stress Level in Domestic Canines
ABSTRACT
The domestic dog is a ubiquitous species having frequent encounters with humans; in the U.S. over 4 million of these result in a dog bite. These injuries might be reduced by improving human-canine communication. Canine responses to alterations of human facial expressions were recorded. The dogs’ responses to the presence of a human experimenter were subsequently analyzed against survey data collected by the shelter on the individual animals (time in shelter, age, sex, reason surrend ...More »
