The purpose of this study was to determine the effects of various structural support configurations in preventing topical compression in skyscraper buildings. To conduct this investigation, the following four support configurations were tested: a single/double vertical support system, a single diagonal/single vertical system, a double cross diagonal, and a double diagonal/double vertical config...

We study the electronic transport in a one-dimensional disordered chair with bath site-diagonal and off-diagonal (hopping) disorder, the latter being perfectly correlated ta the diagonal disorder at the nearest neighbor sites in a linear fashion. Since we allow the hopping m the perfect leads ta be dilferent from the average hopping in the sample, the

We investigate the sensitivity of femtosecond Fourier transform two-dimensional infrared spectroscopy to protein secondary structure with a study of antiparallel beta-sheets. The results show that 2D IR spectroscopy is more sensitive to structural differences between proteins than traditional infrared spectroscopy, providing an observable that allows comparison to quantitative models of protein...

Complexes containing rat liver 80 S ribosomes, poly(uridylic acid), phenylalanyl-tRNA, elongation factor 1 alpha, and guanylyl(beta, gamma-methylene)-diphosphonate were prepared. Neighboring proteins in the complexes were cross-linked with the bifunctional reagent 2-iminothiolane. Proteins were extracted and then separated into 26 fractions by chromatography on carboxymethylcellulose. Each prot...

A 2D photonic crystal optical switch is proposed based on a rods-in-air square-lattice photonic crystal by removing two cross-lines of rods from a 2D square-lattice photonic crystal to form four optical channels. The simulation results show that, when inserting a single rod along the diagonal line of the intersection area of two removed cross-lines of rods, the position of the single inserted r...

general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...

2014 We study white and weighted averages of observables over all solutions of Thouless Anderson and Palmer equations. For the white average we give analytic results near the transition temperature and near T = 0, in good qualitative agreement with expected results for the Edwards Anderson order parameter. A too high value for the ground state energy is attributed to the non discriminating char...

We are developing a new method using ultrasonic longitudinal and torsional vibration of a hollow-type stepped horn for hole machining. We foresee that the equipment can be simplified and miniaturized. In this paper, ultrasonic vibration sources of a hollow-type stepped horn without a diagonal slits vibration converter and with a diagonal slits vibration converter are used. The longitudinal and ...
