headache for one month. MRI revealed a small expanded nodule in the head of the right caudate nuclei (Fig. 1). It was hyper intense on both T1(left) and T2-weighted (right) images. Bleeding was suspected, however, other causes including tumor could not be excluded at this time. Subsequent angiography showed no abnormality. Her symptom disappeared gradually without any treatment. Four weeks late...

In order to promote the comprehensive utilization of corn straw and development field water-saving irrigation technologies, a kind underground composite pipe-forming device mixed with soil extrusion molding was designed. The key extrusion-forming components affecting forming rate pipe were optimized by taking diameter winch blade, shaft winch, pitch as variables output power test indices. best ...

Fiber-reinforced flexible pipes are subjected to large axial tension loads in deep-water applications, which may result the excessive deformation of pipes. Owing anisotropy composite materials, accurately describing tensile behavior these is difficult. Theoretical, numerical, and experimental methods employed this study investigate mechanical characteristics a glass fiber-reinforced unbonded pi...

This meta-analysis examined the validity of the Graduate Record Examinations (GRE) and undergraduate grade point average (UGPA) as predictors of graduate school performance. The study included samples from multiple disciplines, considered different criterion measures, and corrected for statistical artifacts. Data from 1,753 independent samples were included in the meta-analysis, yielding 6,589 ...

Two glucocorticoid response elements (GREs) located 2.5 kb upstream of the transcription initiation site of the tyrosine aminotransferase gene were identified by gene transfer experiments and shown to bind to purified glucocorticoid receptor. Although the proximal GRE has no inherent capacity by itself to stimulate transcription, when present in conjunction with the distal GRE, this element syn...

in the present research, nonlinear vibration in a coupled system of boron-nitride nano-tube reinforced composite (bnntrc) oil pipes is studied. single-walled boron-nitride nano-tubes (swbnnts) are arranged in a longitudinal direction inside poly-vinylidene fluoride (pvdf) matrix. damping and shearing effects of surrounded medium are taken into account by visco-pasternak model. based on piezoele...
