Effect of interlamellar spacing on the elastoplastic behavior of C70 pearlitic steel: Experimental results and self-consistent modeling [PDF]

open access: yes, 2014
The effect of pearlite microstructure characteristics on strength and deformation of C70 pearlitic steel was investigated. Tensile tests under X-ray diffraction coupled with self-consistent model have been used to identify the role of interlamellar ...

Energy Production and its Characteristics from Four Tropical Trees Species Planted in Short Rotation Woody Systems in Costa Rica

open access: yesBioResources, 2023
Short-rotation crop (SRC) systems with woody species have been planted in Costa Rica. However, information about different tree species and spacing is limited. The objective of the present study was to examine biomass production and the physical, energy,

Social-class differences in spacing and stopping during the historical fertility transition: Insights from cure models [PDF]

open access: yesDemographic Research
BACKGROUND: There is a long-standing debate about the role of spacing and stopping in the fertility transition, fueled by a lack of methods to appropriately model spacing and stopping. Traditional event-history analysis cannot distinguish between the two

Effects of Seedling and Plant Spacing on the System of Rice Intensification (SRI) for Spring Rice (Oryza sativa L. Chaite 2)

open access: yesAgroEnvironmental Sustainability, 2023
System of Rice Intensification (SRI technology) increases rice yields while requiring less water and other inputs. It involves the use of specific management strategies that, when used together, provide rice plants with better-growing conditions than ...

The experimental study and numerical simulation of falling liquid film flow on horizontal tubes [PDF]

open access: yes, 2014
This research is motivated by two observations: No report has been found so far in studies of water falling film up to 100 mm intertube spacing. No simulation analysis of film thickness under influence of intertube spacing in 3 dimensional models ...

Space of Spaces as a Metric Space [PDF]

open access: yesCommunications in Mathematical Physics, 2000
In spacetime physics, we frequently need to consider a set of all spaces (`universes') as a whole. In particular, the concept of `closeness' between spaces is essential. However, there has been no established mathematical theory so far which deals with a space of spaces in a suitable manner for spacetime physics.

k‐space function spaces [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1980
A study is made of the properties on X which characterize when Cπ(X) is a k‐space, where Cπ(X) is the space of real‐valued continuous functions on X having the topology of pointwise convergence. Other properties related to the k‐space property are also considered.

No Robust Effect of Distributed Practice on the Short- and Long-Term Retention of Mathematical Procedures

open access: yesFrontiers in Psychology, 2020
We investigated the effect of distributed practice and more specifically the “lag effect” concerning the retention of mathematical procedures. The lag effect implies that longer retention intervals benefit from longer inter-study intervals (ISIs ...

Plant density of lupine (Lupinus albus L.) intercropping with tef [Eragrostis tef (zucc.) trotter] in additive design in the highlands of Northwest Ethiopia

open access: yesCogent Food & Agriculture, 2022
Intercropping of cereals and legumes is common in Ethiopia. However, intercropping of lupine with tef is a new practice in Northwestern Ethiopia’s tef-based cropping system.

Zirconia monolithic veneers: A durable and cosmetic alternative to regular veneers?

open access: yesAdvances in Human Biology, 2022
Ceramics have greatly evolved since they came into the eye of the dental community. Currently, there is a demand for a highly aesthetic as well as strong restoration and high translucent zirconia fits that criteria pretty well.
