LiF, Mg and Ti cubical TLD chips (known as TLD-100) are widely used for dosimetry purposes. The repeatability of TL dosimetry is investigated by exposing them to doses of (81, 162 and 40.5 mGy) with 662keV photons of Cs-137. A group of 40 cubical TLD chips was randomly selected from a batch and the values of Element Correction Coefficient (ECC) were obtained 4 times by irradiating them to doses...

the demand for low fat snacks is increasing. there are different methods to produce low fat fried products. one of these methods is coating. in this study effect of carrageenan, oil temperature and frying time, on oil uptake of fried products (chips and strips) has been evaluated. samples were deep fried in frying oil (palm olein) at 160, 175 and 190 ºc. in order to evaluate the effect of fryin...

Coral reefs and associated fish populations have experienced rapid decline in the Caribbean region and marine protected areas (MPAs) have been widely implemented to address this decline. The performance of no-take MPAs (i.e., marine reserves) for protecting and rebuilding fish populations is influenced by the movement of animals within and across their boundaries. Very little is known about Car...

An outbreak of gastrointestinal illness occurred amongst attendees of a conference lunch in the Hunter area, New South Wales, in October 2001. A distinctive symptom reported by many ill persons was the presence of oily diarrhoea. The Hunter Public Health Unit investigated the outbreak by conducting a telephone interview of the cohort of conference attendees using a standard questionnaire. Twent...

waste tires, rubbers, plastic and steel materials, normally produced in every society, enter the environment and cause serious problems. these problems may, to some extent, be reduced by finding applications for them in engineering, for example, they can be used for geotechnical applications as backfill material and solving problems with low shear strength soils. such materials may be subjected...

The detection of species substitution has become an important topic within the food industry and there is a growing need for rapid, reliable, and reproducible tests to verify species in commercial fish and seafood products. Increases in international trade and global seafood consumption, along with fluctuations in the supply and demand of different fish and seafood species, have resulted in int...

A small fish model and surface-enhanced laser desorption/ionization time-of-flight mass spectrometry were used to investigate plasma protein expression as a means to screen chemicals for estrogenic activity. Adult male sheepshead minnows (Cyprinodon variegatus) were placed into aquaria for seawater control, solvent control, and treatments of 17beta-estradiol (E2), methoxychlor (MXC), bisphenol-...

different methods have been evaluated for manufacturing the porous ti6al4v alloys according todecreasing stress shielding phenomenon and increasing mechanical compatibility between themetallic components and the host tissue. for this purpose, in this work ti6al4v alloy chips werepressed under 400 mpa pressure and then samples were categorized and heated into two groups at1000 and 1150℃ under a ...

This work evaluated the level of rancidity edible oil in six (6) fried snacks food, namely, beans cake (Akara), groundnut (Kuli-kuli), bread buns, fish, yam chips and potatoes chips, purchased from hawkers Wukari, Taraba State, Nigeria.. The indicators their ranges samples obtained, include, Acid Value (4.10 – 6.90 mgKOH/g), Free Fatty (2.05 3.45 Peroxide (12 46.60 mEq/kg), Moisture Content (4....
