Polypropylene (PP) has poor adhesion to metals and other surfaces for its chemical structure. Hence, chemical modification of PP is necessary for metal surface coating application. In this research, grafting of maleic anhydride (MA) onto co(propylene-b-ethylene) in the presence of a dicumyl peroxide (DCP) was accomplished in a single screw extruder. Characteristics of the modified polymer were ...

In this paper, industrial dyes, Disperse Red and Disperse Orange, were studied as model pollutants to show the excellent performance of olive pomace (OP) in sequestering and recovering these dangerous dyes from wastewater. The nature of interactions involved between dyes and OP were inferred by changing several parameters: contact time, pomace dosage, pH and temperature values. Visible spectros...

This paper investigates near infra-red spectroscopy (NIRS) as an indirect and rapid method to assess the biochemical methane potential (BMP) of meadow grasses. Additionally analytical methods usually associated with forage analysis, namely, the neutral detergent fibre assay (NDF), and the in-vitro organic matter digestibility assay (IVOMD), were also tested on the meadow grass samples and the a...

In vitro studies were initiated to determine the suitability of murine and rat macrophages as delivery vehicles for gold nanoshells in the treatment of gliomas. Visualization of macrophage accumulation in and around gliomas may be accomplished using magnetic resonance imaging (MRI) and superparamagnetic iron oxide nanoparticles (SPIO). The optimal loading of both murine and rat macrophages with...

Clinical examination is non-invasive, but has well-recognized limitations in detecting compensated and uncompensated low flow states and their severity. This paper describes the principles of near infra-red spectroscopy (NIRS) and the basis for its proposed use, in hypovolaemic, cardiogenic and septic shock, for assessing global and regional tissue oxygenation. The vascular occlusion test is ex...

Caudwell Xtreme Everest (CXE) is a large healthy volunteer field study investigating human adaptation to environmental hypoxia. More than 200 individuals were studied at sea-level and in four laboratories on the trek to Everest Base Camp (5,300 m). Fifteen physicians climbed high on Everest and continued the studies as they ascended; eight of these individuals reached the summit of Everest and ...

Modern non-destructive optical-reflectance-based techniques for estimation of pigment (chlorophyll, carotenoid, anthocyanin, and flavonol) contents, the rate of onand off-tree ripening as well as for detection of common physiological disorders, such as sunscald, superficial scald, and water core, and other damages to apple fruit are reviewed with an emphasis on the methods developed by the auth...
