A Systematic Review of Single Nucleotide Polymorphisms and its Association with Eggshell Thickness in Chickens [PDF]

Brazilian Journal of Poultry Science
Eggshell prevents microbial contamination of the egg’s internal content, and its quality determines the commercial acceptance or rejection of eggs.

Global variation and uniformity of eggshell thickness for chicken eggs

Poultry Science, 2012
Damaged eggshells result in losses of eggs. Numerous efforts have been carried out to improve eggshell quality, which may lead to increased eggshell thickness. The conventional way of enhancing eggshell strength with thicker eggshell on average may be replaced by a new strategy to improve eggshell uniformity without increasing eggshell thickness.

Biophysical processes of morphogenesis in lizard lungs

Developmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Multiple dinosaur egg-shell occurrence in an Upper Cretaceous nesting site from Patagonia [PDF]

, 2010
The discovery of hundreds of megaloolithid-type egg-clutches (some including embryos of an indeterminate species of titanosaur sauropods) in several stratigraphical levels of the Late Cretaceous nesting site of Auca Mahuevo (Chiappe et al., 2005 ...

Common lizards break Dollo’s law of irreversibility: genome-wide phylogenomics support a single origin of viviparity and re-evolution of oviparity [PDF]

, 2018
Dollo’s law of irreversibility states that once a complex trait has been lost in evolution, it cannot be regained. It is thought that complex epistatic interactions and developmental constraints impede the re-emergence of such a trait.

Assessment of body weight, egg quality traits and some selected serum electrolyte concentration (Na, K, Ca and P) of three different breeds of pigeon at Rajshahi region, Bangladesh

Journal of Agriculture, Food and Environment, 2021
Pigeons are reared in Bangladesh principally with the interest of nutrition, recreation, religious attitude and an income source to earn a livelihood. The study was conducted for the assessment of characteristics of eggs and

Regulation of Oxygen Vacancies in High Entropy Oxides With Multi‐Layer Eggshell Architectural Framework for Boosting the Electrochemical Performance of Supercapacitors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An oxygen vacancy–rich FeZnCuCoNi high‐entropy oxide was constructed using a dual‐defect engineering strategy. This multi‐layer eggshell‐structured material delivers remarkable electrochemical performance, with high specific capacitance, excellent rate capability, and long‐term cycling stability even after 10 000 cycles.

Effect of bird age and storage system on physical properties of eggs from brown laying hens [PDF]

, 2010
A total of 108 eggs from a group of 100 brown laying hens housed in standard cages were analyzed. Thirty-six eggs were retired when the hens had 30 week of age, other 36 eggs were retired when the hens had 35 week of age and the remaining 36 eggs were ...

Accelerated Steady-State Torque Computation for Induction Machines using Parallel-In-Time Algorithms

, 2019
This paper focuses on efficient steady-state computations of induction machines. In particular, the periodic Parareal algorithm with initial-value coarse problem (PP-IC) is considered for acceleration of classical time-stepping simulations via non ...

Capercaillie (Tetrao urogallus) eggshell pigmentation, maculation and thickness

Ornis Fennica, 2018
Eggshells properties (mainly thickness, pigmentation and shape) vary within avian taxa across species, and intraspecifically with age, environmental conditions or individual features of the animals. The properties and appearance of eggshells are important for successful breeding both for birds kept in captivity and in breeding centres and those living ...
