About the geometrical properties of the root condition for the third order polynomials

open access: yesLietuvos Matematikos Rinkinys, 1999
This paper deals with a root condition for polynomial of the second and third order. We prove the root criterion for such polynomial with complex coefficients and find regions for the root condition in the special coefficients' phase space.

Retrieval of Separated Instruments from Root Canal Space: A Case [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2019
Separation of nickel-titanium instrument during root canal treatment can cause serious complications that may lead to treatment failure. It prevents complete cleaning and filling of the entire root canal space. Retrieval of the instrument should be tried

Different root growth patterns in tomato seedlings grown hydroponically under an electric field [PDF]

open access: yes, 2013
Electric fields can determine changes at morphological and physiological levels in plants. In this study, seedlings of Solanum lycopersicum L., grown hydroponically in a floating system, were exposed to a DC 12.0 V m–1 electric field (EF).

Cointegration, Root Functions and Minimal Bases

open access: yesEconometrics, 2021
This paper discusses the notion of cointegrating space for linear processes integrated of any order. It first shows that the notions of (polynomial) cointegrating vectors and of root functions coincide.

Free Space Iron Pools in Roots [PDF]

open access: yesPlant Physiology, 1985
A rapid and simple method for the determination of a ferric iron pool in the free space of roots is described. Formation of this pool depended on the source of iron in the nutrient solution. During growth in water culture at pH 5 to 6 with Fe-ethylenediaminetetraacetate, a free space pool of 500 to 1000 nanomoles Fe per gram fresh weight was formed in ...

Effect of Immediate and Delayed Post Space Preparation on Apical Leakage Using Three Root Canal Obturation Techniques After Rotary Instrumentation

open access: yesJournal of the Formosan Medical Association, 2011
For teeth that have undergone root canal therapy post fabrication and subsequent crown restoration are often required to increase strength. It is necessary to remove a portion of gutta-percha during post space preparation that may cause displacement of ...

Glycome profiling and immunohistochemistry uncover changes in cell walls of Arabidopsis thaliana roots during spaceflight

open access: yesnpj Microgravity, 2023
A large and diverse library of glycan-directed monoclonal antibodies (mAbs) was used to determine if plant cell walls are modified by low-gravity conditions encountered during spaceflight.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
