Primitive near-rings [PDF]

open access: yes, 1970
The theory of near-rings has arisen in a variety of ways. There is a natural desire to generalise the theory of rings and skew fields by relaxing some of their defining axioms.

Xylem growth rings and leaf phenological patterns in tree species of a subtropical seasonal forest [PDF]

open access: yesActa Botânica Brasílica, 2021
Growth rings have been reported for several tropical species under seasonal precipitation regimes and have often been related to leaf phenology. We investigated growth ring distinctiveness, wood markers, and leaf shedding and flushing patterns of 16 tree

Variables Influencing the Production of Door Jambs from Pinus taeda EGP Panels

open access: yesBioResources, 2022
The influence of coverslip width and the physical arrangement of growth rings were studied relative to laterally glued Pinus taeda wood panels (EGP) used in the manufacture of door jambs, according to the requirements of ABNT-NBR 15.930 (2011).

Survival, growth and carbon content in a forest plantation established after a clear-cutting in Durango, Mexico [PDF]

open access: yesPeerJ, 2020
Background Forest plantations play an important role in carbon sequestration, helping to mitigate climate change. In this study, survival, biomass, growth rings and annual carbon content storage were evaluated in a mixed Pinus durangensis and P.

NEUTROSOPHIC RINGS [PDF]

open access: yes, 2006
In this book we define the new notion of neutrosophic rings. The motivation for this study is two-fold. Firstly, the classes of neutrosophic rings defined in this book are generalization of the two well-known classes of rings: group rings and semigroup ...

Neutrosophic Rings I [PDF]

open access: yes, 2011
In this paper, we present some elementary properties of neutrosophic rings. The structure of neutrosophic polynomial rings is also presented. We provide answers to the questions raised by Vasantha Kandasamy and Florentin Smarandache in [1] concerning ...

Fire records in tree rings of Moquiniastrum polymorphum: potential for reconstructing fire history in the Brazilian Atlantic Forest

open access: yesActa Botânica Brasílica, 2018
Fire disturbance affects the composition, structure and dynamics of vegetation. Historical records of fire events exist in some places, but they are generally limited in temporal and spatial extent.
