The traditional precast concrete column-to-column connections are widely used in the prefabricated frame structures China. However, many studies on joints have demonstrated their complex forms and poor construction efficiency. To overcome these shortcomings, a new type column–column connection with steel plate hoop bolts was designed proposed. In order to reveal seismic performance of this conn...

A total of 312 samples in two experiments were analyzed to determine mean nutrient concentrations of swine lagoons and hoop barns in Kansas. First, in a retrospective study (Exp. 1), we obtained 41 sample analyses from the Kansas Department of Agriculture of sow, nursery, wean-to-finish, finish, and farrow-to-finish operations in 1999. The average total N concentration was 899 ppm (SD = 584 ppm...

We employ the Airy stress function to derive analytical solutions for plane strain static deformations of a functionally graded (FG) hollow circular cylinder with Young’s modulus E and Poisson’s ratio v taken to be functions of the radius r . For E1 and v1 power law functions of r , and for E1 an exponential but v1 an affine function of r , we derive explicit expressions for stresses and displa...

The scleral spur and scleral roll together form a fibrous hoop which may be detached from adjacent structures as a unit. Tensile tests of the spur-roll resemble reported data on sclera. It is proposed that the circular structure of the spur-roll prevents action of the meridional portion of the ciliary muscle on the trabecular meshwork from collapsing the canal of Schlemm.

The expectation values of Wilson loop products for the pure Euclidean Yang-Mills theory on R R given by Ashtekar et al. ALM + 96] are determined directly for all piecewise analytic loops. For this a new kind of hoop independence is introduced and their regularization scheme is slightly modiied.

This paper compares energy use for different pig production systems in Iowa, a leader in US swine production. Pig production systems include not only the growth and performance of the pigs, but also the supporting infrastructure of pig production. This supporting infrastructure includes swine housing, facility management, feedstuff provision, swine diets, and manure management. Six different fa...
