For molecular sexing of the naked mole‐rat (Heterocephalus glaber), we designed a PCR primer set to amplify part of the Y‐linked DBY gene. When this primer set was applied to the samples of known sex with the 16S rRNA gene (16S rDNA) primers as control, PCR products were successfully obtained as two DNA bands in males, a male‐specific 163 bp DBY band and a 446 bp band of 16S rDNA shared with females,...
In this paper, we attempt to show the load effect of a typical HPAS system which is widely equipped in the heave duty vehicles. Firstly, a unit by unit modeling procedure is presented for the four fundamental components: steering column, vane pump, rotary valve and pinion-rack unit. Then, an integrated model of HPAS system is set up. For such a complex model, we find that the vane pump is the key...
Summary. Painful snapping caused by a solitary intra-articular nodular mass was found in 11 knee joints of 8 patients with rheumatoid arthritis. The masses were characteristically situated in the anterolateral aspect of the lateral femoral condyle of each joint, and appeared to jump and slip in and out of the patellofemoral articulation during flexion and extension. The snapping caused by the solitary...
