Stress whitening problem in thermoformed alumina trihydrate (ATH) reinforced poly(methyl methacrylate) (PMMA) was studied. In situ heavy-gage thermoforming of acrylics was entirely replicated under laboratory controlled conditions at different operation parameters. Samples were monitored with optical microscope after the completion of the thermoforming operation. For stress whitening quantifica...

The role of polybrominated diphenyl ethers (PBDE) was investigated in the occurrence of feline hyperthyroidism (FH) by evaluating 15 PBDE congeners in serum from 62 client-owned (21 euthyroid, 41 hyperthyroid) and 10 feral cats. Total serum PBDE concentrations in euthyroid cats were not significantly different from those of hyperthyroid cats. Total serum PBDE in feral cats were significantly lo...

Se bioavailability in commercial pet foods has been shown to be highly variable. The aim of the present study was to identify dietary factors associated with in vitro accessibility of Se (Se Aiv) in pet foods. Se Aiv is defined as the percentage of Se from the diet that is potentially available for absorption after in vitro digestion. Sixty-two diets (dog, n 52; cat, n 10) were in vitro enzymat...

The mineral content of canned (115 °C, 45 min; Fo = 7 min) Atlantic Chub mackerel (Scomber colias) previously subjected to different high-pressure processing (HPP) (200, 400, and 600 MPa for 2 conditions frozen storage times (3, 10, 15 months at −18 °C) was studied. Prior steps modified extensively the contents essential toxic elements, so that substantial changes were produced in fish. Thus, s...

the purpose of this study was to investigate the deposition of the hydroxyapatite (ha) coating via the electrophoresis procedure. the ha deposition was performed in an ethanol, methanol, acetone and isopropanol suspension. methanol was found to be the best deposition media. among the different environmental conditions, including the encapsulation of the samples under two vacuum types of pressur...

background: helicobacter pylori ( pylori ) was the most common cause of chronic gastritis and was linked to peptic ulcer disease and gastric cancer. environmental factors such as water a reservoir of h.pylori which infect human.  a non-culture bacteria in coccoid forms widespread in aquatic environments.the objective of this study  was elevating the diagnostic value of pcr and culture methods f...

rapeseed is one of the important oilseeds, as its oil ranks second in the world after soybean. the rapeseed cultivation has been increased recently in iran. drying of seeds to a safe moisture level is necessary for storage of oilseeds before processing. rapeseed drying conditions affect the seed quality, total oil and germination capacity. hence in this research the effects of different tempera...
