The zinc finger protein, metal response element-binding transcription factor-1 (MTF-1) regulates the expression of genes in response to metal ions and oxidative stress. The precise mechanisms by which this occurs are not understood. To further examine this problem, mouse MTF-1 was expressed in Saccharomyces cerevisiae and tested for the ability to activate metal response element-driven reporter...

Thermal infrared imagery plays an important role in a variety of fields, such as surface temperature inversion and urban heat island effect analysis, but the spatial resolution has severely restricted potential for further applications. Data fusion is defined data combination using multiple sensors, fused information often better results than when sensors are used alone. Since multi-resolution ...

The contrast of X-ray imaging depends on the radiation energy and acquires its maximum value at a certain optimum energy typical for the object under investigation. Usually, higher energies result in reduced contrast, lower energies are absorbed in the object thus having a smaller probability of reaching the detector. Therefore, broad X-ray spectra contain non-optimal quanta to a large extent a...

Step-index optical fibers are widely used waveguides for light transmission. However, non-linear effects are always a severe challenge for optical fibers with increasing power level. This challenge is more severe at shorter wavelengths, where core size has to be much smaller in order to maintain a single mode operation. For an example, for 0.005 core refractive index with respect to cladding, a...

In this paper, a kind of temperature sensor for fermentation bed in large scale chicken farm was studied. The sensing equipment includes housing, circuit board and probe detection sensor. is provided with microprocessor wireless Bluetooth communication module. detecting fixedly connected the at least two elements are arranged inside elements, which spaced tube. element module respectively. used...

The aim ot fhe present work was to compare the penetration in muscle tissue fluid (MTF) and muscle tissue (MT) of cephalotin administered in rabbits. Animals were distributed in Trial 1 (n = 15) and Trial 2 ( n= 6). In the Trial 1 the animals were implanted in ischiotibial muscle with non reactive material cages. Animals recibed subcutaneously (sc) cephalotin (20 mg/kg) and blood, MTF and MT sa...

In this work the results on imaging and spectroscopic performances of 14×14×1 mm CdTe detectors with 55×55 μm and 110×110 μm pixel pitch bump-bonded to a Timepix chip are presented. The performance of the 110× 110 μm pixel detector was evaluated at the extreme conditions beam line I15 of the Diamond Light Source. The energy of X-rays was set between 25 and 77 keV. The beam was collimated throug...

An extension of the traditional modulation transfer function (MTF), the detective MTF, is proposed for the evaluation of the resolution of X-ray imaging detectors with non-uniform efficiency on the scale of individual detector elements. The dMTF is shown to give a better representation than does the MTF of the improved resolution reported when the readout of the detectors is enhanced.
