Monitoring the effect of biosynthesized nanoparticles against biodeterioration of cellulose-based materials by Aspergillus niger

Amr Fouda, Gomaa Abdel-Maksoud, Mohamed Ali Abdel-Rahman, Ahmed Mohamed Eid, more

Cellulose > 2019 > 26 > 11 > 6583-6597

Historic cultural heritage and archival manuscripts have a significant importance worldwide and efforts should be considered to preserve such property for as long as possible. The current study aimed to establish a non-toxic, and eco-friendly conservation strategy for retarding paper biodeterioration. To this end, fungal isolates associated with the biodeteriorated paper manuscripts of the historical...

Investigation methods for evaluating the preservative organic mixtures applied on a Late Period mummy

Gomaa Abdel-Maksoud, Hany El-Shemy, Mostafa Abdel-Hamied

Archaeological and Anthropological Sciences > 2019 > 11 > 5 > 1843-1850

The resins and other biochemical substances in mixtures have an important role in achieving the preservation goal for mummification process. The identification of organic mixtures is vital in the conservation field of the unwrapped mummies, but their identification is sometimes difficult because of improper conditions, which can affect their structure and need good investigation techniques for their...

Implementation of spectroscopic techniques for characterization of icons of Deir El Sankoria, El Minia, Egypt

Gomaa Abdel-Maksoud, Yousry M. Issa, Mina Magdy

Measurement > 2016 > 91 > C > 210-220

Four icons from church of Saint Theodore El Shatby, Deir El Sankoria, El Minia, Egypt, have studied by micro-destructive spectroscopic methods: Attenuated Total Reflection–Fourier Transform Infrared Spectroscopy (ATR–FTIR), Raman Spectroscopy (RS), Field Emission Scanning Electron Microscopy–Energy Dispersive X-ray Spectroscopy (FESEM–EDX), X-ray Photoelectron Spectroscopy (XPS) and Inductively Coupled...

Analytical study of Saint Gregory Nazianzen Icon, Old Cairo, Egypt

Yousry M. Issa, Gomaa Abdel-Maksoud, Mina Magdy

Journal of Molecular Structure > 2015 > 1100 > Complete > 70-79

The study aims to evaluate the state of icon through characterization of the icon layers (ground, paint and varnish layers) and to provide tools for assessment the impact of aging and environmental conditions in order to produce some solutions for conservation of the icon. Analytical techniques used in this study were attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR),...

The Orthopedic Diseases of Ancient Egypt

Klaus O Fritsch, Heshem Hamoud, Adel H. Allam, Alexander Grossmann, more

The Anatomical Record > 298 > 6 > 1036 - 1046

Background: CT scanning of ancient human remains has the potential to provide insights into health and diseases. While Egyptian mummies have undergone CT scans in prior studies, a systematic survey of the orthopedic conditions afflicting a group of these ancient individuals has never been carried out. Methods: We performed whole body CT scanning on 52 ancient Egyptian mummies using technique comparable...

Analytical techniques used for the evaluation of a 19th century quranic manuscript conditions

Gomaa Abdel-Maksoud

Measurement > 2011 > 44 > 9 > 1606-1617

The manuscript studied here dates to 19th century, and consists of paper pages and leather bookbinding. This study aims to use analytical techniques in order to identify the components of the manuscript and to explain its deterioration process. Visual assessment, isolation and identification of fungi, pH measurements, and investigation of the surface morphology by a scanning electron microscope (SEM)...

Effect of burial environment on crocodile bones from Hawara excavation, Fayoum, Egypt

Gomaa Abdel-Maksoud, Mohamed Abdel-Hady

Journal of Cultural Heritage > 2011 > 12 > 2 > 180-189

Many different archaeological materials were found in Hawara (Fayoum, Egypt) during the excavation of the Egyptian–Polish mission in 2008. A complete crocodile skeleton, and many incomplete crocodiles were found in this area. The skeletons of these crocodiles suffered from salt crystallization, erosion, pitting, change of the color, etc. This study focuses on the mechanism of deterioration processes...

Damage caused by insects during the mummification process: an experimental study

Gomaa Abdel-Maksoud, Ezz Eldin Abed al-Sameh Al-Shazly, Abdel-Rahman El-Amin

Archaeological and Anthropological Sciences > 2011 > 3 > 3 > 291-308

The process of mummification had been known since the Fourth Dynasty of the Old Kingdom (ca. 2600 bc) and continued to develop throughout ancient Egyptian history. Although mummification protected the body from decay, especially by microbes, some mummification techniques left the body susceptible to insect attack. Certain types of insects have been detected in the mummies. In scholarly publications,...
