fication Corrosion monitoring by resistivity measurement was used to assess the environmental conditions in cultural heritage institutions, with the aim to provide advice on the preservation conditions in museums, showcases or storage areas. Changes in corrosion depth of thin copper sensors were followed during a year. The results of studies in 13 museums, libraries and archives are presented. ...

Additional resistances contributed to that of PdHx electrode in an electrolyte using the direct current method are calculated. It is found that an electrode with a large ratio of length to radius, an active surface, a surrounding electrolyte with high conductance and high electrolysis current will induce substantial additional resistances.

When the end-point is reached in the HardyWolff method of measuring pain threshold, there is a sharp change in the subjective experience resulting from the stimulus. When the radiation intensity is below the level of the pain threshold, the sensation is one of heat alone. If the pain threshold is exceeded, there is a sensation of heat with an added factor which has been variously described as "...

The Channel-Spark method was used for deposition of highly oriented ferromagnetic La 0.7 Sr 0.3 MnO 3 films on NdGaO3 substrates. It was found that additional oxygen decreases the film quality suppressing the Curie temperature and metal-insulator transition below the room temperature. To achieve the best quality of the films the samples were either annealed in high vacuum at deposition temperat...

Using contact measurements, experimental evidence was obtained for the existence of the rolling resistance moment. The critical rolling distance prior to detachment is reported. Previously it has been argued that the critical rolling distance should be related to the lattice size and/or the molecular length of the particle and surface materials. However, there has been no theoretical prediction...

Cored Nb-Ti Rutherford cables with high crossover resistance R, a re being investigated to minimize ac losses in a set of superconducting dipole magnets for the proposed rapid cycling heavy ion synchrotron facility a t the Gesellschaft fiir Schwerionenforschung (GSI) in Darmstadt, Germany. This ring of magnets is based on the Relativistic Heavy Ion Collider (RHIC) design. R, in cored cables is ...

objective(s)bioelectrical impedance is the measure of impedance of the body. impedance consists of electric resistance and reactance. phase angle (pa) is the tan value of the ratio of reactance versus electric resistance. pa depends on cell membrane integrity and on body cell mass. there exists a correlation between pa values and body cell mass.the objective of this study was to compare the pa ...

An apparatus has been designed and constructed to characterize thermal interface materials with unprecedented precision and sensitivity. The design of the apparatus is based upon a popular implementation of ASTM D5470 where well-characterized meter bars are used to extrapolate surface temperatures and measure heat flux through the sample under test. Measurements of thermal resistance, effective...

errors in blood pressure (bp) measurement are common in the clinical practice. inaccurate measurements of bp may lead to misdiagnosis and inappropriate treatment of hypertension. the preferred method of bp measurement in the clinical setting is a scultation, using the first and the fi fth korotkoff sounds. however, the use of mercury sphygmomanometer is declining. automated oscillometric device...

We study the strain state of doubly clamped VO2 nanobeam devices by dynamically probing resonant frequency of the nanoscale electromechanical device across the metal-insulator transition. Simultaneous resistance and resonance measurements indicate M1-M2 phase transition in the insulating state with a drop in resonant frequency concomitant with an increase in resistance. The resonant frequency i...
