Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

open access: yessteel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Experimental Evidence for Mobilization of Mercury From the Eggshell by the Developing Embryo in an Avian Model Organism

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via maternal offloading in eggs, with higher mercury concentrations found in shells of unhatched eggs.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Usability of CART algorithm for determining egg quality characteristics influencing fertility in the eggs of Japanese quail

open access: yesRevista Brasileira de Zootecnia
The objective of this study was to determine the effects of egg quality characteristics (egg weight, egg width, egg height, and shape index) on fertility of eggs of Japanese quail with different colored feathers (yellow, white, grizzled, and normal ...

More Than Words: The Multimodal Practice of Repetition in English as a Lingua Franca Interactions

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This study investigates the use of repetition as an interactional resource in video‐recorded English as a Lingua Franca (ELF) interactions, focusing on partial repeats produced in responses to wh‐questions. By adopting a multimodal conversation analytic approach, the analysis demonstrates that repetition in this context may either index the ...

Silent Spring - the lost call [PDF]

open access: yes, 2008
The "silence" in Rachel Carson's Silent Spring1 alludes to the demise of bird populations through reproductive problems and death resulting from exposure to the pesticides of that time, many of which are endocrine active.

mRNA Expression of Cytochrome P450 17αhydroxylase, Cytochrome P450 Aromatase, Anti-Müllerian Hormone, Estrogen Receptor α, and Androgen Receptor in Developing Gonads of Japanese Quail

open access: yesThe Journal of Poultry Science, 2008
Japanese quail (Coturnix coturnix japonica) is widely used in avian reproduction tests and avian sex reversal screening tests for evaluating adverse effects of endocrine disrupting chemicals (EDCs).

Linguistic Justice in World Englishes: A View From Cultural Appropriation

open access: yesWorld Englishes, EarlyView.
ABSTRACT This article highlights the need to better clarify what we understand by linguistic justice. Failure to do so poses the danger that the concept not only remains something we may clamour for but is also one that we are unable or unwilling to recognize should we ever encounter it.

Propolis alleviates the negative effects of heat stress on egg production, egg quality, physiological and immunological aspects of laying Japanese quail.

open access: yesPLoS ONE, 2019
The present work was carried out to investigate the effects of dietary propolis supplementation to laying Japanese quail (Coturnix coturnix japonica) on egg production, egg quality, physiological and immunological aspects under heat stress conditions.
