Investigations by Raman microscopy, ESEM and FTIR-ATR of wall paintings from Qasr el-Ghuieta temple, Kharga Oasis, Egypt

Influence of cutting height and plant spacing on Sesbania (Sesbania aegyptiaca [Poir]) productivity under hyper-arid conditions in El-kharga Oasis, El-Wadi El-Gaded, Egypt

Search for an adapted forage species for feed production under existing marginal lands and harsh conditions is needed to overcome sever feed shortage in Egypt. Sesbania, Sesbania aegyptiaca (Sesbania sesban, L) has shown potential for forage production and being included in grazing systems, especially on marginal lands and salt–affected soils. An experiment was conducted in the summer of 2004 a...

Identification of selected seaweed polysaccharides (phycocolloids) by vibrational spectroscopy (FTIR-ATR and FT-Raman)

The wide industrial application of phycocolloids (e.g. alginates, agar and carrageenans) is based on their particular properties to form gels in aqueous solution. These seaweed polysaccharides present a chemical structure related with the taxonomic position of the algae: carrageenans are produced by carrageenophytes (red algae belonging mainly to the genera Kappaphycus, Eucheuma, Chondrus, Giga...

Survey on Sarcocystis in bovine carcasses slaughtered at the municipal abattoir of El-Kharga, Egypt

AIM The main objectives of this study were to determine the incidence of Sarcocystis sp. infection in cattle and buffalo carcasses slaughtered at El-Kharga abattoir, New Valley Governorate, Egypt. MATERIALS AND METHODS The slaughtered animals were daily inspected for Sarcocystis macrocysts through a year (2015). Macroscopic Sarcocystis was detected from a total of 2120 cattle and buffalo carc...

Remote Roman Fortifications: The Forts of the Kharga Oasis

Compositional and quantitative microtextural characterization of historic paintings by micro-X-ray diffraction and Raman microscopy.

This work shows the benefits of characterizing historic paintings via compositional and microtextural data from micro-X-ray diffraction (μ-XRD) combined with molecular information acquired with Raman microscopy (RM) along depth profiles in paint stratigraphies. The novel approach was applied to identify inorganic and organic components from paintings placed at the 14th century Islamic Universit...
