background: one of the methods used for joining metals together is welding, which can be carried out using different techniques such as electric spot welding. this study evaluated the effect of electric spot welding on the load defl ection rate of stainless steel and chromium-cobalt orthodontic wires. materials and methods: in this experimental-laboratory study, load defl ection rate of 0.016 ×...
Estimating the arm-wise false discovery rate in array comparative genomic hybridization experiments.
Array Comparative Genomic Hybridization (aCGH) is an array-based technology which provides simultaneous spot assays of relative genetic abundance (RGA) levels at multiple sites across the genome. These spot assays are spatially correlated with respect to genomic location and, as a result, the univariate tests conducted using data generated from these spot assays are also spatially correlated. I...
Alpha toxin derived from Clostridium perfringens was used for diagnosis of Streptococcus agalactiae (St.agalactiae) by rapid and spot CAMP tests. The selected Cl.perfringens strain was cultured in optimized conditions; the supernatant of culture was concentrated by ultra filter and purified by DEAE cellulose chromatography. The efficacy of both purified and crude α-toxins were examined by rapid...
The aluminum alloys of Al1050 with thickness of one millimeter and Al3105 with thickness of half millimeter were joined via ultrasonic spot welding (USW). To create a suitable welding, a vibrating horn (welding tool) fit to transducer and ultrasonic generator was designed using ANSYS software. Due to mechanical and thermal cycles during USW, both diffusion and mechanical mixing facilitated the...
Validation procedures are described for 12 chemical spot tests including cobalt thiocyanate, Dille-Koppanyi, Duquenois-Levine, Mandelin, Marquis, nitric acid, para-dimethylaminobenzaldehyde, ferric chloride, Froehde, Mecke, Zwikker and Simon's (nitroprusside). The validation procedures include specificity and limit of detection. Depending on the specificity of each color test, between 28 to 45 ...
We present a case of a 14-year-old previously healthy boy with acute hepatotoxicity after noni berry juice consumption. As the popularity of noni berry consumption continues to increase, heightened awareness of the relation between noni berry consumption and acute hepatotoxicity is important.
The relation between level crossings, entanglement, and Berry phases is investigated for the Breit-Rabi Hamiltonian of hydrogen and sodium atoms, describing a hyperfine interaction of electron and nuclear spins in a magnetic field. It is shown that the entanglement between nuclear and electron spins is maximum at avoided crossings. An entangled state encircling avoided crossings acquires a marg...
Coloured afterimages were obtained after fixation of a neutral grey spot on a coloured surround The colour of the spot afterimage was similar to that of the previous surrounding area. and was found to have two components which could be elicited independently. Firstly. complementary afterimages were generated by the subjective contrast colour which was induced into the grey spot during the adapt...
PURPOSE A newly developed head-mounted perimeter termed "imo" enables visual field (VF) testing without a fixed head position. Because the positional relationship between the subject's head and the imo is fixed, the effects of head position changes on the test results are small compared with those obtained using a stationary perimeter. However, only ocular counter-roll (OCR) induced by head til...
Length-biased data are widely seen in applications. They are mostly applicable in epidemiological studies or survival analysis in medical researches. Here we aim to propose a Berry-Esseen type bound for the kernel density estimator of this kind of data.The rate of normal convergence in the proposed Berry-Esseen type theorem is shown to be O(n^(-1/6) ) modulo logarithmic term as n tends to infin...
