BACKGROUND Nickel ferrite, a kind of soft magnetic materials is one of the most attracting class of materials due to its interesting and important properties and has many technical applications, such as in catalysis, sensors and so on. In this paper the synthesis of NiFe2O4 nanoparticles by the hydrothermal method is reported and the inhibition of surfactant (Glycerol or Sodium dodecyl sulfate)...

BACKGROUND The standardized protocol for performing the strip patch test has proven to be valid, but evidence on its reliability is still missing. OBJECTIVE To estimate the parallel-test reliability of the strip patch test as compared with the conventional patch test. METHODS In this multicentre, prospective, randomized, investigator-blinded reliability study, 132 subjects were enrolled. Si...

Abstract An entirely femtosecond laser (fs-laser) based process for the production of stable, enlarged and alloyed nickel surfaces is presented. The allows use metal foils aqueous salt solutions as alloying element sources. We alloy iron from an source well molybdenum cobalt commercially available on mesh without further coating process. It shown that content surface structured with fs-laser de...

Abstract Transportation is one of the main sectors contributing to greenhouse gas (GHG) emissions that cause global climate change. One decarbonization strategies from transportation sector can be implemented by switching a sustainable mode transportation, especially battery electric vehicles (BEV). Since mid-2021, Obi Island has been producing Mixed Hydroxide Precipitate (MHP). It an intermedi...

BACKGROUND A chronic dermatosis like nummular dermatitis may be complicated by contact dermatitis due to an impaired cutaneous barrier. This study is aimed at evaluating secondary contact dermatitis in patients with nummular dermatitis. METHODS Patch testing with the Indian Standard Series was performed in 50 of 78 patients with a clinical diagnosis of nummular eczema. Significant reactions w...

The impact of legacy nuclear waste on the compositional diversity and distribution of sulfate-reducing bacteria in a heavily contaminated subsurface aquifer was examined. dsrAB clone libraries were constructed and restriction fragment length polymorphism (RFLP) analysis used to evaluate genetic variation between sampling wells. Principal component analysis identified nickel, nitrate, technetium...

Luminol, leuchomalachite green, phenolphthalein, Hemastix, Hemident, and Bluestar are all used as presumptive tests for blood. In this study, the tests were subjected to dilute blood (from 1:10,000 to 1:10,000,000), many common household substance, and chemicals. Samples were tested for DNA to determine whether the presumptive tests damaged or destroyed DNA. The DNA loci tested were D2S1338 and...
