The proposed light-frame structure comprises steel columns for vertical loads and an innovative bracing system to efficiently resist seismic actions. This seismic force resisting system consists of a light timber frame braced with an Oriented Strand Board (OSB) sheet and an external technoprene plaster-infilled slab. Steel brackets are used as foundation and floor connections. Experimental cycl...

BACKGROUND Relapsing fever (RF) spirochetes are notable for multiphasic antigenic variation of polymorphic outer membrane lipoproteins, a phenomenon responsible for immune evasion. An additional role in tissue localization is suggested by the finding that isogenic serotypes 1 (Bt1) and 2 (Bt2) of the RF spirochete Borrelia turicatae, which differ only in the Vsp they express, exhibit marked dif...

We discuss the Manned SpacePlane (MSP) project and its foundation for the Virtual SpacePlane (VSP) project. We present the requirements for the Virtual SpacePlane as derived from the MSP project’s objectives. The VSP requirements coupled with the need to rapidly assemble a prototype led us to reuse code from the Virtual Cockpit, Solar System Modeler, and Common Object Database (CODB) systems. W...

field observations of the incurred damages to the buildings and bridges due to earthquakes in near field show there are various failure modes which are in relation to the forces caused by vertical component. while vertical component of earthquake for ordinary buildings in most seismic regulations and standards is not considered. therefore, in the current study the effects of vertical and horizo...

In this paper, a new seismic site classification for the Costa Rican Strong-Motion Network (CRSMN) is proposed. The soil profile of Seismic Code based on average shear-wave velocity top 30 m (VS30) used as reference. fundamental period (Tf) included parameter to complement existing characterization. For this, VS30 measurements from 52 accelerometric stations are related obtained through horizon...

Aspect graph is an important method in 3D object recognition. To effectively compute the viewpoint space partition (VSP) is critical in acquiring a good aspect graph. In this paper, we present improvements to the VSP algorithm under perspective model: computing EV (Edge Vertex) events using triangle face feature; simplifying VSP representation; boundary intersection updating; closed loop region...

In Escherichia coli and related bacteria, the very-short-patch (VSP) repair pathway uses an endonuclease, Vsr, to correct T-G mismatches that result from the deamination of 5-methylcytosines in DNA to C-G. The products of mutS and mutL, which are required for adenine methylation-directed mismatch repair (MMR), enhance VSP repair. Multicopy plasmids carrying mutS alleles that are dominant negati...

This article addresses the question whether time-lapse seismic reflection techniques can be used to follow and quantify the effects of solution salt mining. Specifically, the production of magnesium salts as mined in the north of the Netherlands is considered. The use of seismic time-lapse techniques to follow such a production has not previously been investigated. For hydrocarbon production an...

Vegetative storage protein (VSP) and VSP mRNA levels in soybean (Glycine max) leaves correlated with the amount of NH(4)NO(3) provided to nonnodulated plants. The mRNA level declined as leaves matured, but high levels of N delayed the decline. This is consistent with the proposed role for VSP in the temporary storage of N. Wounding, petiole girdling, and treatment with methyljasmonate (MeJA) in...
