Current Tris-based solutions for DNA electrophoresis produce a positive feedback loop between current and temperature at high voltage, resulting in long running times for the separation of even small DNA fragments. We optimized the separation of small DNA fragments (90-300 bp) in polyacrylamide-based electrophoresis at high voltages (200volts/cm) by substituting Tris with low concentration alkali salts (e.g. 1 mm LiCl and CsCl). These media reduced the heat produced during electrophoresis, enhanced the DNA fragment resolution, and allowed gels to be run at higher voltages, reducing gel running times by 25%. In addition, the elimination of Tris and EDTA from the buffer reduced material costs approximately 10-fold. © 2006 The Authors. [less ▲]

Eight kinds of typical coal samples were chosen for studying the influence of coal characteristics on laser—induced plasmas.Element analysis and industry analysis were carried out for every sample.Experimental study on the interaction between laser and different coal samples was completed,and factors affecting laser plasma were analyzed,such as coal moisture and coal dust.The experiment result indicates that the coal samples with different coalification degrees have different plasma time—resolved spectral characteristics,all of them tend to rise at the beginning of plasma formation (< 1us),then with the decay of plasmas emission.they tend to decrease in about 1us,while secondary ionization occurs in highly coalificated coals after 2 us.The plasma temperature differs from one kind to another,the higher the coalification degree is,the higher the plasma temperature will be.

One near infrared (NIR) reflectance and five dielectric moisture meters were tested for their capability of measuring moisture content (MC) in solid biofuels. Ninety-eight samples were tested at up to eight moisture levels covering the MC range from fresh fuel to approximately 10% MC (w.b.). The fuel types ranged from typical solid biofuels such as coniferous and deciduous wood chips over short rotation coppice (SRC) to sunflower seed and olive stones. The most promising calibrations were obtained with the NIR reflection method and two dielectric devices where the sample is placed in a container integrated in the device. The calibration equations developed show that there is a profound influence from both laboratory and fuel type. It is suggested that individual calibrations that are based on the specific fuel types used at the individual heating plant could be applied. [less ▲]

The aim of the current paper was to elaborate an immobilization method of thrombin receptor agonist peptide (TRAP-6) in biodegradable biocompatible poly(d,l)-lactide-co-glycolide (PLGA) inicroparticles and to demonstrate the effect of the entrapped peptide for tissue repair, namely,for a gastric ulcer treatment in rats. TRAP-6 was entrapped in polymer using w/o/w double emulsion-evaporation technique. The morphology of empty and TRAP-6 loaded microparticles was evaluated by light and scanning electron microscopy (SEM). In vitro release kinetics profile of TRAP-6 from microparticles was studied by HPLC. To investigate gastric mucosal protection effect in vivo, TRAP-6-loaded microparticles were administered in a rat stomach after a previous mucosal injury (a gastric ulcer). Microparticles with entrapped TRAP-6 were found to reduce both an inflammation and proliferation phases of wound healing, and thus accelerated tissue repair in rats. [less ▲]

Chronic arterial hypotension has been poorly studied. Its mechanisms are not well understood; its treatment (if needed) is disappointing, without any demonstrated improvement of symptoms or prognosis. Thus, a complete medical examination is needed to exclude any organic cause. If none is found, it is important to reassure the patient and to convince him not to use expensive drugs potentially generative of side effects. [less ▲]

In Belgium, the Boom Clay is being evaluated as a potential host formation for the disposal of high-level nuclear waste. In order to investigate this option, an underground research facility composed of two access shafts and 200m of galleries was excavated. Excavation induced fractures were observed in a zone of approximately 1 m around the galleries. In this study, the potential effect of these fractures on radionuclide migration in the Boom Clay is investigated. Therefore, a hydrogeological model of the clay is built with a radionuclide source in the middle of the clay layer surrounded by different fracture configurations. Two types of fracture configurations are inserted in the model. The first type of fracture properties is drawn stochastically from the probability distributions of the properties of the fractures observed around previously excavated galleries. These fracture patterns are considered to be realistic although in this study it is conservatively assumed that no self-sealing occurs. The model is run for a large number of stochastically drawn fracture configurations and the results are compared to a model without fractures. These calculations show that the radionuclide fluxes through the clay are not significantly influenced by these fractures. For the second type of fracture configurations, the fracture properties are varied over a much larger range. Hypothetical fractures with much higher values of fracture extent, aperture, dip and frequency than observed are modeled, With these hypothetical fracture configurations, the critical values of the fracture parameters are determined that must be exceeded to have a significant effect on the radionuclide fluxes through the clay. These calculations show that the extent of the fractured zone has the largest effect on radionuclide migration. The other fracture parameters (aperture, spacing and dip) have a limited effect on the radionuclide fluxes. To obtain a total radionuclide flux through the lower clay boundary that is respectively 10%, 50% and 100% larger than without a fractured zone, the extent of the hypothetical fractured zone should be respectively 27.97 m, 43.86 m and 46.92 m. Such fractures are not expected to be generated by mechanical excavation in the Boom Clay. The obtained critical extent values of the hypothetical fractures are a factor 30 to 40 higher than the measured values of the extent of the excavation disturbed zone. These calculations thus indicate that it is very unlikely that the extent of the fractured zone around the galleries will be large enough to have a significant effect on the radionuclide fluxes through the Boom Clay. This conclusion is further supported by the conservative assumption that no self-sealing occurs. These calculations can function as a preliminary robustness test in ongoing safety analysis studies.

The analytic properties of the elastic hadron scattering amplitude are examined in the impact parameter representation at high energies. Different unitarization procedures and the corresponding non-linear equations are presented. Several unitarisation schemes are presented. They lead to almost identical results at the LHC. [less ▲]
