Precast prestreesed concrete braces are a new method for seismic strength of Concrete Structures which has the following benefits: a) no wet concrete work in construction site b) No bolt or anchorage to the existing frame c) easy to apply d) short construction period e) low construction cost, to evaluate seismic performance of strengthened structure a model consist of existing frame and concret...
in this paper, a new method for determining position and orientation of a coordinate system using its image is presented. this coordinate system is a three dimensional non-orthogonal system in respect to the two dimensional and orthogonal camera coordinate system. in real world, it’s exactly easy to select three directions on an object so that they don’t be orthogonal and on a plane. the image...
let $l$ be a completely regular frame and $mathcal{r}l$ be the ring of continuous real-valued functions on $l$. we show that the lattice $zid(mathcal{r}l)$ of $z$-ideals of $mathcal{r}l$ is a normal coherent yosida frame, which extends the corresponding $c(x)$ result of mart'{i}nez and zenk. this we do by exhibiting $zid(mathcal{r}l)$ as a quotient of $rad(mathcal{r}l)$, the ...
A 65−year−old man was referred to our de− partment for polypectomy. A polyp, 20 mm in diameter, was found in the as− cending colon on colonoscopy (Figure1 a). The polyp surface was covered by charac− teristic multiple dimples, long thin ves− sels, and mucus. Chromoendoscopy with 0.4% indigo carmine enhanced the ap− pearance of the polyp surface dimples, and subsequent magnification revealed a t...
Tumor cell progression and parenchyma! infiltration play important roles in the pathogenesis of gliomas. Using retrovirally marked rat 9L gliosarcoma cells, which when injected in the CDF rat brain form noninfiltrating tumors which grow only surrounding existing blood ves sels, we were able to investigate elements of tumor growth and progression within the substance of the brain. Transfection o...
