Bioassay bashing is bad science.

Science Bashing: Is it a global In-thing?

Ridiculing the well established knowledge and norms in the various branches of science like medical science, physics, chemistry, astrophysics, genetics etc. has become a new fashion all over the world. There is always a place for constructive critics and scientists will be grateful to anybody who finds any other ways of knowing things and they will be greatly relieved to say good bye to the exi...

Bioassay of Chlorsulfuron Residue in Soil by Using Cress (Lepidium sativum L.) Plant as an Indicator

Comparative Evaluation of Three Different Methods of Genomic DNA Extraction for

Extraction of DNA from Staphylococcus aureus is often difficult and less efficient. In this study, the relative recovery of extraction of staphylococcal DNA from pure culture was compared using rapid lysis, bashing beads and commercial silica column methods. For both methicillin resistant and sensitive Staphylococcus aureus the DNA extracted by rapid lysis method was found to have higher value ...

Estimation of Returns to Scale in the Presence of Undesirable (bad) Outputs in DEA when the Firm is Regulated

The calculation of RTS amounts to measuring a relationship between inputs and outputs in a production structure. There are many methods to measure RTS in the primal space or the dual space. One of the main approaches is using the multiplier on the convexity constraint. But returns to scale measurements in DEA models are affected by the presence of regulatory constraints. These additional constr...
