this study was carried out to detect the presence of aflatoxin m1 (afm1) in 30 uht flavored milk samples in karaj, alborz province of iran. high-performance liquid chromatography (hplc) was applied to analyse afm1 in the samples. result showed that aflatoxin m1 was detected in all the uht flavored milk samples, the concentration of afm1 was ranged from 0.015 to 0.14 µg/kg. also, 10 samples (33....

High-power arc lamp design has enabled ultrahigh-temperature sUHTd annealing as an alternative to conventional rapid thermal processing sRTPd for ultrashallow junction formation. The time duration of the UHT annealing technique is significantly reduced from those obtained through conventional RTP. This difference in time may offer the ability to maintain a highly activated ultrashallow junction...

Decision-making under ambiguity in cognitive bias tasks is a promising new indicator of affective valence in animals. Rat studies support the hypothesis that animals in a negative affective state evaluate ambiguous cues negatively. Prior automated operant go/go judgement bias tasks have involved training rats that an auditory cue of one frequency predicts a Reward and a cue of a different frequ...

Twelve different liquid market milks of Bangladesh were examined to evaluate their chemical and sanitary quality. Six of these were open raw milk bought from local daily markets and the other six were processed packet milk (both pasteurized and UHT [Ultra High Temperature] processed) available in shops. The twelve samples were examined for the determination of percentage of water, total soluble...

The relation between age gelation and proteolytic activity was investigated in this study, as proteolysis is considered to be one of the principal factors that cause gelation. Two different methods for measuring the proteolytic activity of milk samples were applied; the measurement of absorbance at 280 nm and the trinitrobenzene sulfonic acid (TNBS) method. The milk samples used were raw and UH...

Long range dependent (LRD), stationary time series have historically served to model real time series with apparent changes in local mean level. A natural tool to study changes in local mean level is unbalanced Haar wavelet transformation (UHT). In this work, UHT is used to study changes in local mean level in LRD models and several real and simulated time series exhibiting LRD. In particular, ...

This study was carried out to detect the presence of aflatoxin M1 (AFM1) in 30 UHT flavored milk samples in Karaj, Alborz province of Iran. High-performance liquid chromatography (HPLC) was applied to analyse AFM1 in the samples. Result showed that aflatoxin M1 was detected in all the UHT flavored milk samples, the concentration of AFM1 was ranged from 0.015 to 0.14 µg/kg. Also, 10 samples (33....

Background: Aflatoxin M1 (AFM1) as a carcinogenic and toxic compound has considerable significance from public health viewpoint. The aim of this study was to determine the level of AFM1 in pasteurized and UHT milk in West-Azerbaijan province of Iran. Methods: A total of 360 commercial milk samples including 220 pasteurized milk and 140 ultra-high-temperature (UHT) milk were purchased randoml...

Development of malodourous compounds, hexanal and p-vinyl guaiacol (PVG), in UHT model liquid systems fortified with wholegrain oat were evaluated. Single and mixed systems using oat powder (3, 5, and 7% w/w), skim milk powder (SMP, 2.8% w/w) and sucrose (6.7% w/w) were subjected to UHT treatment and 29 days ambient storage. Both chromatographic analyses and panellists' perceived aroma intensit...

A transmission electron microscope (TEM) study of Paleoproterozoic zircon that has experienced ultra-high temperature (UHT) metamorphism at ca. 570 Ma in the Kerala Khondalite Belt (KKB), southern India, documents the occurrence of metallic Pb nanospheres. These results permit comparison with a previous report from UHT zircon in Enderby Land, Antarctica, and allow further constraints to be plac...
