Obj.ctive: We investigated rates of p.ostate cancer (p.a), high-grade p.ostatic intraep.thelial neop.aisa (HGp.N) and atyp.cal small acinar p.oliferation (ASAp. in a multiethnic cohort. Methods: We evaluated p.ostate biop.y outcomes in men enrolled in the San Antonio Center of Biomarkers of Risk for p.ostate cancer (SABOR) p.osp.ctive, observational study. p.a-free men underwent annual p.A testing over nearly 14 years with biop.ies based on community standards. We investigated biop.y outcomes with a sp.cial interest in rates of cancer, HGp.N, and ASAp. Results: We identified 975 p.ostate biop.ies in 801 subj.cts from 3/1/2001 to 1/9/2014. p.a, HGp.N, or ASAp.was encountered in 28.8% (281/975), 10.1% (98/975), and 5.2% (51/975) of p.ostate biop.y sp.cimens, resp.ctively. The most significant risk factor for a p.a diagnosis was African American race (OR 5.0, 95% CI: 2.2 - 11.4, p.p.N and ASAp.occurred more commonly in association with p.a (both p.p.e-malignant” lesion on p.ostate biop.y and had a subsequent biop.y. Of those only 8% (2/24) were diagnosed with p.ostate cancer (both Gleason 3 + 3) within 1 year of the initial biop.y. Conclusion: We note a 5-fold increased risk of p.a for African American men. The incidence of HGp.N and ASAp.are consistent with p.eviously rep.rted incidence. If diagnosed in isolation, rep.at biop.y within one year could be delayed or eliminated as it may not change p.ostate cancer outcomes.

＜正＞ This p.p.r rep.rts some observations on the behaviour of a segregated p.rticle bed consisting of a mixture of small and large p.rticles in the transverse p.ane of a rolling mode rotating drum. A non-invasive p.sitron emission p.rticle tracking （p.RT） technique was used to follow the traj.ctories of different sized p.rticles. A two-dimensional mathematical model based on the Eulerian ap.roach and the thin layer ap.roximation was develop.d to simulate solids motion and concentration distribution of different sized p.rticles. It is shown that the bed structure for a binary mixture is similar to that for mono-sized p.rticles, i.e. two-region structure consisting of a relatively thin ’active’ region and a ’p.ssive’ region near the drum wall where p.rticles move as a rigid body. At low rotational sp.eds, the velocity difference between small and large p.rticles of a binary system is negligible in both the active and p.ssive regions. At relatively high rotational sp.eds, the velocity difference is small in the active region and negligible in the p.ssive region. Radial occup.ncy data suggest that small p.rticles tend to concentrate in the core region, whereas large p.rticles tend to occup. the shell region, in good agreement with model p.edictions. Axial occup.ncy data reveal that the axial p.rticle mobility increases with drum rotational sp.ed, and the mutual diffusivity of small p.rticles is higher than that of large p.rticles. It is also shown that the turnover time ratio of small to large p.rticles is almost indep.ndent of concentrations of small p.rticles under the conditions of this work. 2002 Elsevier Science Ltd.

制革生产中的准备工段因其不清洁性而被人所知。超过60％总污染来自于浸灰-复灰工序。石灰和硫化钠的使用是完全根据经验而没有量化标准的。石灰因其低的溶解度有使皮逐步膨胀的能力；然而，石灰的使用目前引起了很多环境的关注。大量的石灰泥和固体物的形成是石灰的主要缺点。硫化物是污水处理厂中的有害物质。这主要是因为石灰，硫化钠，水和其他化学材料没有合理化的使用。一个使准备工段化学材料得到最合理使用的方法已经产生。这种方法是基于常规分散纤维的膨胀仅仅需要20％～40％水（以浸水前的生皮重为用料依据）这一事实上的。在理论上，这就使得仅仅使用常规浸灰-复灰化学材料用量的十分之一就能维持相同的浓度剃度成为可能。这种方法使用40％的水，0．35％的硫化钠和1．0％的石灰在浸灰中，40％的水和1．0％石灰在复灰中，在转鼓中处理和常规方法相同的时间。复灰后采用了经济性的操作和方法。一个使用常规浸灰-复灰方法的常规实验和此实验方法同时进行。实验结果表明新方法脱毛完全，而且纤维束的松散程度可以和用常规方法处理过的纤维松散度相比。通过扫描电镜，铬的层分布和柔软度的测量方法证实了这种方法的可实施性。通过物理的和人为的评价，这种方法得到的革的性质能和常规松散纤维法得到的革的性能可以相提并论。尤其是革的柔软度已经被用数字证明是可以和传统方法得到的革的柔软度相比的。这种方法同常规方法相比，减少了给环境造成的85％的化学耗氧量和12％的总固量。处理一吨生皮在浸灰-复灰中的产生的总干泥从152公斤降到了6公斤，这一点是第一次被论证。
