Effectiveness of nitrogen fixation in rhizobia

open access: yesMicrobial Biotechnology, 2019
Biological nitrogen fixation in rhizobia occurs primarily in root or stem nodules and is induced by the bacteria present in legume plants. This symbiotic process has fascinated researchers for over a century, and the positive effects of legumes on soils ...

A STUDY OF FIXATION FOR ELECTRON MICROSCOPY

open access: yesJournal of Experimental Medicine, 1952
Osmium tetroxide fixation of tissue blocks, as usually effected, is preceded by an acidification of the tissue. This acidification is probably responsible for morphological alterations which are notably disturbing in electron microscopy.

Outcome of Transpedicular Screw Fixation with Posterior Interbody Fusion in Management of Spondylolysthesis. [PDF]

open access: yesInternational Journal of Medical Arts, 2020
Background: Spondylolysthesis represents a particular and relatively frequent mechanism of intervertebral instability. It could cause low back pain due to forward or anterior displacement of one vertebra in relation the adjacent lower vertebra. There are

Comparison Between Unilateral and Bilateral Sacrospinous Ligament Fixation for Management of Vault Prolapse [PDF]

open access: yesInternational Journal of Medical Arts, 2020
Background: Hysteropexy is an effective procedure for vault prolapse as abdominal sacrocolpopexy but easier and simple. Right sacrospinous fixation has the same results of bilateral fixation.

To Fix or Not To Fix: Controls on Free-Living Nitrogen Fixation in the Rhizosphere

open access: yesApplied and Environmental Microbiology, 2019
Free-living nitrogen fixation (FLNF) in the rhizosphere, or N fixation by heterotrophic bacteria living on/near root surfaces, is ubiquitous and a significant source of N in some terrestrial systems.
