Biodiesel is considered to be more friendly the environment than petroleum-based fuels, cheaper and capable for producing greener energy which contributed positively in boosting bio-economy. In this work, waste cooking oil (WCO) converted into biodiesel utilizing a eggshell (CaO) nano-catalyst an effort discover environmentally beneficial economically viable processes social economic developmen...

The world’s waste deposit has become more important due to the growth of world economy and demography. Biomethanation is method choice for treatment fermentable fractions municipal waste. However, low methane yield operational issues process instability prevent this technology from being widely applied. It shows that biogas made up approximately 50-70% CH 4 ; 30-50% CO 2 traces other gases. Sol...

This research investigates the removal of textile dyes (Rhodamine B and Alizarin Red S) from aqueous solution by a low-cost adsorbent prepared eggshell waste. Batch adsorption experiments were conducted in order to determine effect different parameters such as pH, dye concentration, contact time, dosage, particle <br /> size, temperature. The best correlation was found Langmuir model, max...

This study investigated the effects of Fe-soy proteinate (Fe-SP) and magnesium oxide (MgO) dietary supplements on eggshell quality in laying hens. A total of 800 26-wk-old Hy-Line Brown hens were assigned to four dietary treatments: control (C), FeSP 100 (100 ppm Fe-soy proteinate), MgO (3 g MgO/kg diet), and Fe-SP 100+MgO. Each treatment had five replicates of 40 hens. The FT-IR (Fourier trans...

In this project, eggshell membrane was used as a solid phase extraction sorbent for extraction of morphine followed by HPLC analysis. At first, raw eggshell membrane was used and then, because of low adsorption of morphine on untreated eggshell membrane (<70%), modification of eggshell membrane surface was carried out using different surfactants and amines. The amine modified eggshells characte...

A study was conducted to evaluate skeletal quality and eggshell parameters of molted hens at the end of the second laying cycle. Sixty Single Comb White Leghorn hens were used for this study. There were 2 controls and 4 molting treatments: full-fed control 1 (82 wk old; FF1), full-fed control 2 (122 wk old; FF2), feed withdrawal (FW), 100% alfalfa (A100), 90% alfalfa/10% layer ration (A90), and...

BACKGROUND Clinically, sclerosing thoracic disc herniation is a disease with high surgical risk and various complications. Eggshell procedure is a surgical method used by surgeons to treat sclerosing thoracic disc herniation. The aim of this study was to report a modified eggshell procedure to treat sclerosing thoracic disc herniation. METHODS Medical records of 25 patients with sclerosing th...

Egg hatching has been studied in Aedes aegypti (L.) through scanning electron microscopy. The first sign of egg hatching is a small protrusion on the eggshell in the anterior pole. The larval movement provokes a crack in the eggshell with the egg buster located in the dorsal head. The egg buster provokes a small transverse fissure in the eggshell that gradually increases in the chorion. Then, t...

It was previously reported (Tuan, 1980a) that the development-specific expression of calcium transport and related functions in the chick embryonic chorioallantoic membrane (CAM) requires the continuous presence of the eggshell, the calcium source of the embryo. To further understand the mechanism of action of the eggshell on the CAM functions, this study reports the effects of eggshell supplem...
