Smarandache near-rings [PDF]

open access: yes, 2002
The main concern of this book is the study of Smarandache analogue properties of near-rings and Smarandache near-rings; so it does not promise to cover all concepts or the proofs of all ...

Maiasaura (Dinosauria: Hadrosauridae) Tibia Osteohistology Reveals Non-annual Cortical Vascular Rings in Young of the Year

open access: yesFrontiers in Earth Science, 2019
Annually, tetrapod vertebrate bone apposition is briefly interrupted, which typically coincides with the yearly environmental nadir. The temporary appositional hiatus is histologically recorded in bone cortex as a hypermineralized ring termed a line of ...

Smarandache Non-Associative (SNA-) rings [PDF]

open access: yes, 2005
In this paper we introduce the concept of Smarandache non-associative rings, which we shortly denote as SNA-rings as derived from the general definition of a Smarandache Structure (i.e., a set A embedded with a week structure W such that a proper subset ...

Morphological and anatomical characterization of Qualea dinizii Ducke (Vochysiaceae) applied to the identification of Brazilian Amazon forest species [PDF]

open access: yesBrazilian Journal of Biology
Knowledge of Amazonian tropical forest species depends on accurate identification and characterization, which are legal requirements for sustainable forest management, traceability, appropriate end use, and control of the forest production chain. However,

Pointer years in the growth of beech trees of the NP "Đerdap" area [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2014
This paper defines pointer years and years with distinctive tree rings in the growth of beech in 3 sites (ecological units-EU) of the area of Đerdap, in order to observe the reactions of trees to the effects of various factors of growth.

Characterizations of rings and modules by means of lattices [PDF]

open access: yes, 1965
PhDIn this thesis we study the relationship between the lattice of submodules and the algebraic structure of a module. The key remark in our study will be the fact that the homomorphisms between two independent submadules of a module can be ...

Energetic impact of reconstructed debris flow on the intensity and duration of growth disturbances in tree rings

open access: yesFrontiers in Earth Science, 2023
A rare study on the quantitative relationship between the energetic impact of debris flows on the intensity and duration of growth disturbances of tree rings was carried out, partly due to a lack of feasible approaches and detailed field evidence.

Annual tree rings in Piptadenia gonoacantha (Mart.) J.F.Macbr. in a restoration experiment in the Atlantic Forest: potential for dendroecological research

open access: yesActa Botânica Brasílica, 2016
The tree Piptadenia gonoachantha is widely used in forestry and in forest restoration projects, which require methods for evaluating tree growth. Long-term studies are necessary to determine patterns and detect changes in species growth rhythms.
