The respiration of individual 'Hass' and 'Fuerte' fruit was monitored during storage at 8oC and 10oC respectively for 14 days, under a continuous flow of humidified air containing ethylene (C2H4) at 0, 0.01, 0.05, 0.25, 1.0 and 5.0 μL.L. Respiration rates of 'Fuerte' fruit under 0.01 μL.L C2H4 were significantly higher than the controls after 3.3 days of storage, but for 'Hass' fruit respiratio...

Ochratoxin A (OTA) is a naturally occurring fungal metabolite produced by some species of Aspergillus and Penicillium. OTA being nephrotoxic, carcinogenic, hepatotoxic and immunosuppressive imparts many human and animal health hazards. In this study OTA production was observed at different temperatures (5oC, 10oC, 20oC, 30oC and 40oC) in three substrates (corn, rice and wheat) by A. ochraceus a...

The objective of this study was to determine the prevalence of hepatitis B and C among the patients who came for dental treatment to Bacha Khan Medical & Dental College, Mardan. Four hundred patients formed the study group. The blood samples of all these patients were taken in the hospital laboratory and were screened for HBsAg and Anti HCV using immunochromatography (ICT) method. The blood was...

Energy harvesting is a process in which energy which would otherwise be wasted is captured, stored and then used to power a system. Devices having such capabilities enjoy an extended life particularly advantageous in systems with limited accessibility, such as biomedical implants and structure embedded micro and wireless sensors. A viable family of materials for this purpose is piezoelectric ma...

ABSTRACT Because of the severity of heavy metal contamination and potential adverse health impact on the public, tremendous efforts have been made to purify waters containing toxic metal ions. Biosorption is presented as an alternative to traditional physicochemical means for removing toxic metals from groundwaters and wastewaters. Removal of lead from solution was studied using growing cells a...

We have measured elastic (bulk and shear modulus) and acoustic (compressional and shear wave velocities) properties of heavy-oil sands over a range of frequencies (2− 2000Hz) covering the seismic bandwidth and at ultrasonic frequencies (0.8MHz). The measurements were carried on heavy-oil sand sample from Asphalt Ridge, Utah at a constant temperature ( 20oC) and different confining pressures usi...

Nanoscale multilayer nitride coatings deposited by advanced PVD techniques have shown particular promise in improving the tribological properties of a number of modal alloy steels [1]. In this study, we report the effect of temperature on the friction and wear behaviour of a CrAlYN/CrN multilayer coating with a CrAlYON/CrON topcoat deposited on γ-TiAl. Deposition was performed by unbalanced mag...

The present work is aimed at evaluating the effect of slurry ice as a preliminary treatment prior to frozen storage. For it, specimens of a small pelagic fatty fish species (sardine; Sardina pi...

Submersed weeds on irrigation systems reduce water delivery capacity, clog pumps and structures, rupture canals, increase leakages and losses of water, increase water costs, etc. (U.S.EPA, 2007). Herbicide applications are a commonly used procedure to control submersed weeds in irrigation canals because of its practicability, efficacy and cost. Acrolein, currently registered under the trade nam...

Accurate measurements of water vapor in the Arctic winter, either in situ or remote, are difficult to achieve. These measurements are important to studies in infrared radiative transfer. To focus on measurements during cold temperatures (< 20oC) and low amounts of vapor (Precipitable Water Vapor, 5 mm), an Intensive Operating Period (IOP) was conducted at the U.S. Department of Energy’s Atmosph...
