My aim is to question whether the introduction of new technologies in society may be considered to be genuine experiments. I will argue that they are not, at least not in the sense in which the notion of experiment is being used in the natural and social sciences. If the introduction of a new technology in society is interpreted as an experiment, then we are dealing with a notion of experiment ...

animal experimentation is carried out in consultation with the veterinary wing but it is essential that be familiar with experimental protocols of animal model to be able to design an approriate study. this is more so in place where the veterinary facilities are not easily available.span rabbits are commonly used as subjects for screening implant material. they have gained favour for their nume...

according to the temperature distribution of water injection well-bore in highly deviated wells under different conditions and unstable temperature field heat conduction principles, a true three-dimensional model was established to analyze the law of variation on temperature of highly deviated wells during the water injection process, and to analyze the factors that influence the water injectio...

the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...

The ideas used in experiments today were mostly in place by the first few decades of the 20th century. The procedures of comparing groups, assigning individuals to treatments, and statistically analyzing group comparisons had been developed by 1940. During the 1960s, the types of experimental designs were identified and the strengths (e.g., control over potential threats) of these designs speci...
