Characterisation and adsorption properties of calcinated eggshell, salicylic acid-modified eggshell, and 2, 4-dihydroxy benzoic acid-modified eggshell

, 2021
This study synthesised eggshell waste, an agricultural by-product, into a calcinated porous material modified by salicylic acid as a new and effective adsorbent for remediation of Cu(II) from an aqueous solution.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Breeding Dispersal of Baltic Dunlins Is Not an Adaptive Response to Unpredictable Nest Flooding

Animal Conservation, EarlyView.
Flood‐related nest losses of the Baltic dunlin (Calidris alpina schinzii) have drastically increased over the past two decades. Using 20 years of reproductive data from 184 individuals, we found that between‐year and within‐site dispersal tended to increase following nest failure in males.

Acute and chronic eggshell temperature manipulations during hatching term influence hatchability, broiler performance, and ascites incidence

, 2015
The aim of the current study was to determine how a control temperature and acute and chronic high eggshell temperatures during the last three days of incubation, can affect hatchability, chick quality, and organ development on day of hatch as well as ...

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae

Acta Zoologica, EarlyView.
ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

EFFECT OF EGGSHELL CONDUCTANCE CONSTANT ON EMBRYONIC INTESTINE FUNCTION, HATCHING CHARACTERS AND SUBSEQUENT GROWTH FOR DEVELOPED CHICKENS AND ITS RELATION WITH 2- FLOCK AGE [PDF]

Egyptian Poultry Science, 2017
The present experiment was carried out for studying the effect of eggshell conductance constant (K) on embryonic intestinal function, hatching success, some physiological parameters and post-hatch growth for two flock ages (39-42 vs.

Egg Chorion Morphology and Egg‐Laying Behaviour of Backswimmer Notonecta viridis Delcourt, 1909 (Heteroptera: Nepomorpha: Notonectidae)

Acta Zoologica, EarlyView.
ABSTRACT In this study, the egg‐laying behaviour and chorionic morphology of the eggs of the backswimmer Notonecta viridis Delcourt, 1909 (Heteroptera: Notonectidae) were described in detail using stereo, light and electron microscopy. Female N. viridis lays its eggs individually, horizontally attached to the surface. Eggs are elliptical, approximately

EFFECT OF DIFFERENT CALCINATION TEMPERATURES ON SYNTHESIZED HYDROXYAPATITES FROM WASTE EGGSHELL

Eskişehir Technical University Journal of Science and Technology A - Applied Sciences and Engineering
About 94% of waste eggshells are composed of calcium carbonate (CaCO3), which allows for the generation of calcium oxide (CaO), which can be utilized to synthesize hydroxyapatite (HAp). This study uses chemical precipitation and calcination methods to synthesize natural HAp from eggshell waste.

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 1. Methods to Improve Insect Collection and Parasitoid Pupariation

Entomologia Experimentalis et Applicata, EarlyView.
We describe methods for collecting and rearing the tachinid parasitoid Istocheta aldrichi from parasitized Japanese beetle adults. Hosts can be collected by hand and reared in the laboratory, or by using modified trap containers with added plant material and substrate to provide suitable conditions for I.
