Miniaturized detection systems for nanometer-sized airborne particles are in demand, as in applications for onboard diagnostics downstream particulate filters in modern diesel engines. A soot sensor based on resistivity measurements was developed and characterized. This involved generation of soot particles with properties similar to diesel engines using a(More)
To control the environmentally detrimental impact of acid rock drainage, two different countermeasures, layers of acid-buffering materials and sodium dodecyl sulphate addition, were tested for their efficiency in laboratory percolation experiments. In the experiment with a layer of calcium bentonite, only the iron output was reduced. The experiments with(More)
Vitiligo is an acute disease of skin with inflammation which means damage of melanocites, their defined partial paint lack. It is a frequent sickness which is very conspicuous and disturbing illness. For its treatment, systematically and topically psoralen-derivatives, UV-A radiation and other possibilities are used. Metoxsalen is one of them which is(More)
This paper presents the thermal performance of a proposed thermal management device (patented in 2009) intended for a thermophoretic based soot sensor. The performance was studied for temperatures ranging from 50°C to 400°C and for exhaust speeds up to 10m/s. It also presents the design and basic concepts. The performance study and design(More)
Cholesterolemia in a population of 100482 inhabitants of the Bihor district, subjected to screening for the risk factors in ischemic cardiopathy were studied. Together with hyperlipidemias other risk factors were detected: arterial hypertension, obesity, diabetes mellitus, smoking, ischemic alterations of the electrocardiogram, the influence of the noxious(More)
