Transforming deoxyribonucleic acid (DNA) preparations from Haemophilus influenzae Rd strains carrying a chromosomally integrated, conjugative, antibiotic resistance transfer (R) plasmid were exposed to ultraviolet radiation and then assayed for antibiotic resistance transfer on sensitive wild-type Rd competent suspensions and on similar suspensions of a uvr-1 mutant unable to excise pyrimidine ...

3D printing and nanotechnology have been two of the most important tools in development personalized medical treatments. More recently, their alliance has developed an effort to create new, flexible, multidisciplinary, and/or drug-wise products. Therefore, a comprehensive review scientific studies, including nanomaterials on new pharmaceutical methods applications for treatment prevention disea...

Abstract Ni-Ti-Cu alloy can not only prevent scale and biological adhesion, but also has applications in aerospace, automotive engineering, nanotechnology. In this study, Ni 50 Ti 40 Cu 10 45 15 large-size thin-walled parts are prepared on the surface of plates using laser additive manufacturing technology. The optimum operational parameters explored through a two-factor controlled variable met...
