TL;DR: In this paper, the first mode response of a linear multistorey structure with a linear vibration absorber attached to the roof is derived and the smallest possible values of the variance of the response along with corresponding absorber parameters are established using an optimization program.
Abstract: The equations of motion are derived for the first mode response of a linear multistorey structure having a linear vibration absorber attached to the roof. Furthermore, the variance of the first mode response to a gaussian white noise lateral base acceleration (as a model of earthquake excitation) is determined. Smallest possible values of the variance of the response along with corresponding absorber parameters are established using an optimization program. It is demonstrated that the absorber is quite effective in reducing first mode response for 5- and 10-storey structures even with relatively small values of the absorber mass. Moreover, minimal responses for the randomly excited single-degree-of-freedom system have been determined, and a design example is presented. The absorber system has potential application not only in earthquake engineering but also in aerospace and terrestrial vehicle design.

TL;DR: In this article, the irregularities in the magnetization of ferromagnetic crystals were studied by means of magnetic particles about 1.6mm in diameter suspended in ethyl acetate.
Abstract: Irregularities in the magnetization of ferromagnetic crystals were studied by means of magnetic ${\mathrm{Fe}}_{2}$${\mathrm{O}}_{3}$ particles about 1\ensuremath{\mu} in diameter suspended in ethyl acetate. On iron crystals the particles settle along parallel lines spaced about 0.1 mm apart and more or less at right angles to the applied field. On nickel crystals the pattern is similar, but the lines split up into more complicated structures as the applied field is increased. On cobalt crystals straight lines are obtained on some crystals, and spotty patterns on others. The spots arrange themselves in rows when the crystals are magnetized. The patterns can be destroyed by relatively slight surface strains. There is some evidence that in the straight line patterns the direction of the lines is related to the direction of magnetization. An explanation of these effects is not known.

TL;DR: The theory of field-modified energy bands is extended to include the effect of weak scattering forces on the energy band structure in this article, where anomalous currents of a type previously treated by Karplus and Luttinger (Phys. Rev. 95, 1154) in connection with electrical conduction in ferromagnets are discussed.

18 Jul 1991TL;DR: In this article, an electrochemical apparatus is made having a generator section (22) containing electrochemical cells, a fresh gaseous feed fuel inlet (28), and at least one hot Gaseous spent fuel recirculation channel (46), passing from the generator chamber to combine with the fresh feed feed inlet to form a reformable mixture.
Abstract: An electrochemical apparatus (10) is made having a generator section (22) containing electrochemical cells (16), a fresh gaseous feed fuel inlet (28), a gaseous feed oxidant inlet (30), and at least one hot gaseous spent fuel recirculation channel (46), where the spent fuel recirculation channel (46), passes from the generator chamber (22) to combine with the fresh feed fuel inlet (28) to form a reformable mixture, where a reforming chamber (54) contains an outer portion containing reforming material (56), an inner portion preferably containing a mixer nozzle (50) and a mixer-diffuser (52), and a middle portion (64) for receiving spent fuel, where the mixer nozzle (50) and mixer-diffuser (52) are preferably both within the reforming chamber (54) and substantially exterior to the main portion of the apparatus, where the reformable mixture flows up and then backward before contacting the reforming material (56), and the mixer nozzle (50) can operate below 400°C.

TL;DR: In this paper, the authors assessed the relationships among sampling effort, reach length sampled, and asymptotic species number in small (mean, 4.5 m low-flow wetted width), relatively species-rich (maximum, 30 species), first- to third-order southeastern coastal plain streams.
Abstract: To accurately estimate the number of species in stream fish assemblages, the reach length that is sampled must be increased until species number approaches an asymptote. Sampling effort affects the proportion of the assemblage that is sampled at any point along a stream and hence the reach length at which the asymptote is attained. 1 assessed the relationships among sampling effort, reach length sampled, and asymptotic species number in small (mean, 4.5 m low-flow wetted width), relatively species-rich (maximum, 30 species), first- to third-order southeastern coastal plain streams. With seven electrofishing passes, which sampled an estimated 60–90% of the fish at most of the 25 sample sites, reach lengths of 235–555 m (equivalent to 35–158 stream widths) were needed to collect all species; higher ratios of reach length to stream width were needed in smaller streams. With one electrofishing pass, which sampled an estimated 20% of the fish, reach lengths needed to be increased by factors of 3–4 to ...
