Mating system and genetic diversity of a rare desert legume Ammopiptanthus nanus (Leguminosae)

引用

Journal of Systematics and Evolution 2009年第1期47卷 57-66页

作者： Daniel J crawford Department of Ecology and Evolutionary Biology and the Natural History Museum and Biodiversity Research CenterThe University of Kansas

Ammopiptanthus nanus is an endangered evergreen shrub endemic to the deserts of central Asia and plays an important role in delaying further desertification. We examined allozyme variation and AFLP diversity in A. nanus populations and investigated the mating system of this species using progeny arrays assayed for poly-morphic allozyme loci. Mating system analysis in the Keyi’eryongke’er population showed low levels of out-crossing, and strong inbreeding depression. Low levels of genetic variation were detected at both population (allozyme, Pp=14.0%, A=1.14, He=0.031; AFLP, Pp=14.5%, Shannon’s information index I=0.063) and species (allozyme, Pp=21.1%, A=1.21, He=0.040; AFLP, Pp=20.9%, I=0.083) levels; while moderate genetic differentiation existed among populations, as indicated by allozymes (GST=0.081) and AFLP (GST=0.151-0.193). Founder effect, bottlenecks in evolutionary history, the mixed mating system and co-ancestry may have influenced the level of genetic diversity in A. nanus. Markers of both types provide new insights for conservation management, indicating that the Biao’ertuokuoyi and Keyi’eryongke’er populations should be given priority for in situ conservation and regarded as seed sources for ex situ conservation.

Simulation of Fragment Impact on Multi-Layer Targets Using Contact Method

引用

Transactions of Tianjin University 2006年第B09期12卷 152-157页

作者： crawford John E Karagozian & Case 2550 N.Hollywood WaySuite 500BurbankCA 91505USA

Cased explosives generate highly energetic fragments as their casing breaks up. Due to the complexity of casing fragment related behavior such as embedment, perforation and ricochet, it may be insufficient to use equivalent triangular pressure loading in fragment impact simulations. This simplified method may over- or under-predict the target response. Recently, a procedure using contact techniques has been proposed to overcome such difficulties. It has been shown that the new method has the inherent capability in modeling the multi-piece and multi-hit fragment impact problems in a more realistic way. To investigate the applicability of the proposed method to simulations involving multi-layer penetration, the selected problems of fragment impact on multi-layer targets are described in this paper. It is demonstrated that this method is capable of predicting the complicated multi-layer structural response caused by fragment impact and penetration. Modeling procedures and some technical issues are also discussed.

Development of Light Weight Structures to Provide Blast-Resistant Designs

引用

Transactions of Tianjin University 2006年第B09期12卷 16-21页

作者： crawford John E Karagozian & Case 2550 N.Hollywood Way #500BurbankCA 91505USA

In the past, blast-resistant designs for structures were often constructed with massive type structural systems, which relied more on brute strength than on finesse to achieve the required blast resistance. However, structures composed of COLD-FORMED steel components, such as sheet metal and metal studs, have shown great promise in providing blast resistance with the added benefits of low cost and ease of construction. Some examples of using such structures to provide containment for package handling facilities (PHF) are described in the paper for situations where blast containment is needed, such as a potential package bomb being discovered during the package vetting process. Results from tests and analytic data are used to illustrate aspects of design peculiar to such types of applications. Designs for specific capacities of PHF are described.

＜正＞A method to electropoiish niobium with continuous current oscillation is introduced. The current continuously oscillates for as long as 3 hours. The key is to maintain continuous agitation of the acid mixture. A niobium surface treated by this method has suppressed grain boundaries and a lower hydrogen content. The method has been used to electropoiish L-band half-cells. The test results of a 1500 MHz cavity made of electropolished half-cells are presented.

Multi-length scale modeling is performed to(i)predict the carburized case depth of SAE8620 steel gears by solving the Fick’s second law of diffusion,(ii)model the martensitic microstructure evolution in a grain inside the carburized case as well as to study the effect of stress cycling on retained austenite(RA)and martensite using a 3D phase-field model,(iii)simulate the effect of carburization and different RA contents on macroscale fatigue behavior of SAE8620 steel spur gear using the finite element *** diffusion model predicts that the case depth increases with increasing heat treatment time and *** phase-field simulations show that RA can transform to martensite during fatigue loading,where the extent of the transformation will depend on the type of stresses applied,*** in a high stress regime or low stress regime of fatigue *** transformation of martensite to austenite is also observed in low RA sample under high stress *** macroscale simulations show that the carburized case with high RA gives rise to better fatigue life compared to that with low RA.

Prostate-specific antigen （PSA） screening： has the pendulum swung too far？

引用

Asian Journal of Andrology 2011年第5期13卷 655-656页

作者： Jason M Phillips E David crawford Department of Urology University of Colorado HealthSciences Center Aurora CO 80045 USA

Prostate-specific antigen （PSA） along with digital rectal exam has been the standard for prostate cancer screening in the United States for the past 20 years.1 During this time period, the improved detection of prostate cancer decreased related mortality more than 30%.2 In fact, metastases and their comorbidities have decreased more than 75% since the early 1990s, resulting in a higher incidence of early organ-confined disease. While it is clear that prostate cancer mortality statistics have improved, it is unclear whether men are overscreened.
