Bacterial spore formers are being used as probiotic supplements for human dietary supplements as well as in registered medicines and for use in animal feeds. Their heat stability and ability to survive the gastric barrier makes them attractive as food supplements and this use is now growing. While often considered soil organisms this conception is misplaced and Bacilli should be considered as g...

The discharge flow technique has been used with resonance fluorescence detection of N atoms to study the fast radical-radical re ction ofground state nitrogen atoms (4S3/2) with NO and NO 2. The rate constants obtained are (in units of cm 3 molecule -• s -j) k• = (2.2 + 0.2) x 10-•1exp[(160 + 5 )/T] in the temperature range 213 K _< T _< 369 K for N + NO --> N 2 qO and k 2 = (5.8 + 0.5) x 10 -1...

Aims: The National Institute of Health and Clinical Excellence (NICE) recommend that at the end of an operation ‘surgical incisions anticipated to heal by primary intention should be covered by a film membrane, with or without a central absorbent pad’. The objectives of this project were to measure the usage and acceptability of a postoperative dressing, and evaluate the use of resources and in...

An InAlAs/InGaAs HEMT with an InAs-rich barrier spacer (In0.52Al0.48As) to reduce the parasitic resistance is reported. Devices were obtained with a source resistance of 170 V-mm. A 40 nm gate length In0.7Ga0.3As HEMT with Lside 1⁄4 100 nm and tins 1⁄4 10 nm shows excellent transconductance and subthreshold characteristics including gm 1⁄4 1.6 mS/mm, DIBL 1⁄4 122 mV/V and S 1⁄4 80 mV/ dec at VD...

We study disordered systems at and near quantum phase transitions, which are transitions at zero temperature that are driven by quantum instead of thermal uctu-ations. Special emphasis is put on the so-called Griiths-McCoy regions surrounding these transitions in magnetic systems, where various susceptibilities are found to be divergent for T ! 0 without the system being critical. We present a ...

We have investigated the effects of modification of the SrTiO3/Co interface as well as the SrTiO3 barrier on the tunnel magnetoresistance TMR of La0.67Sr0.33MnO3/SrTiO3/Co junctions. Modification was realized by the introduction of one atomic layer of either TiO2 or SrO at the SrTiO3/Co interface. Barriers with different oxygen content were also studied. In these structures we have observed pos...

Homogeneous nucleation of the new phase of one transition near a second phase transition is considered. The system has two phase transitions, we study the nucleation of the new phase of one of these transitions under conditions such that we are near or at the second phase transition. The second transition is an Ising-like transition and lies within the coexistence region of the first transition...

We present measurements of growth rates of the (0001) facet surface of ice as a function of water vapor supersaturation over the temperature range −2 ≥ T ≥ −40 C. From these data we infer the temperature dependence of premelting on the basal surface and the effects of premelting on the ice growth dynamics. Over this entire temperature range the growth was consistent with a simple 2D nucleation ...

We present a static microfluidic device without use of hydrogel barrier for the generation of chemical gradient. The microfluidic device allows for the analysis of bacterial chemotaxis without use of hydrogel, membrane, and pump. We demonstrate a chemotactic response to attractant and repellent by measuring of dynamic change of bacterial population in detection area. In this chemotaxis assay, b...
