Effects of oxygen concentration during incubation and broiler breeder age on embryonic heat production, chicken development, and 7-day performance

open access: yesAnimal, 2021
Older breeder flocks produce eggs with a relatively larger yolk and thereby a higher nutrient availability than young breeder flocks. To optimise nutrient utilisation and embryonic development throughout incubation and posthatch period, embryos ...

Interaction between eggshell temperature and carbon dioxide concentration after day 8 of incubation on broiler chicken embryo development

open access: yesAnimal, 2021
Carbon dioxide (CO2) is considered to be an important factor during incubation of eggs. Effects attributed to higher CO2 concentrations during experiment might be due to confounding effects of other environmental conditions, such as incubation ...

Evaluation of Antimicrobial Activity and Cytotoxicity of an Epoxy Resin-Based Endodontic Sealer Containing Nanoparticles Amorphous Calcium Phosphate

open access: yesInternational Journal of Dentistry, 2023
Background. The main cause of posttreatment disease in endodontics is the remaining of microorganisms within the root canal walls after endodontic therapy. Therefore, it is essential to use root canal sealers with potent antibacterial properties.

Influence of Ultrasonic Irrigation and Chloroform on Cleanliness of Dentinal Tubules During Endodontic Retreatment-An Invitro SEM Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2015
Background: Ultrasonic irrigation has been proved for its remarkable cleaning efficiency in the field of endodontics. But its role in endodontic re-treatment has been understated. There is not much data available to understand the effect of ultrasonic

The Cell Biocompatibility of a new Polycaprolactone-based Endodontics Sealer Compared with AH Plus Sealer

open access: yesOpen Dentistry Journal, 2023
One of the important materials needed for root treatment is the sealers. They fill the space between the gutta and the canal walls and create a suitable seal to prevent the colonization of oral microorganisms in the peri-apical tissues and inside the

The Scaling of the Anomalous Hall Effect in the Insulating Regime [PDF]

open access: yes, 2011
We develop a theoretical approach to study the scaling of anomalous Hall effect (AHE) in the insulating regime, which is observed to be $\sigma_{xy}^{AH}\propto\sigma_{xx}^{1.40\sim1.75}$ in experiments over a large range of materials.
