Lucerne for dryland farming systems in the Queensland subtropics
The degraded fertility of cropping soils in the Queensland grain belt can be improved by using lucerne, either in short or longer-term rotations. Research in collaboration with NSW Agriculture to improve the adoption of lucerne in farming systems, includes breeding and commercialising better cultivars. Lucerne âprobe setsâ, comprising cultivars, accessions and breeder lines, were sown at 5 sites in 1997 to measure their production and persistence and to set genetic ideotype targets for further breeding. Highly winter
active lines were the most productive and there were some winter active lines that expressed strong persistence traits. The winter active benchmark cv. Trifecta has been clearly superseded but production by the highly winter active benchmark, cv. Sequel was exceeded by only cv. Rippa and Y9549. Breeding for higher winter activity is a priority for short-term rotation lucernes for the Queensland grain belt. For this, there is a strong existing germplasm base to combine with well-selected accessions
The Phases and Faces of the Duke Lacrosse Controversy: A Conversation
The genesis of this panel is an essay I wrote arguing that the single moniker Duke lacrosse controversy encapsulates a broad, multi-faceted legal, political, and social controversy that more accurately consists of five related seriatim sub-controversies. Initially, it was a sexual assault case. An African-American woman, hired as an exotic dancer at a party thrown by members of the Duke University men\u27s lacrosse team, reported to Durham police that she had been sexually assaulted by several white team members. The allegations quickly became a national story, tinged with issues of race, class, gender, privilege, and at some level, the role of athletics and athletes in the university community. It then became a story about an overzealous prosecutor and overzealous police, pursuing and obtaining indictments of three players despite mounting evidence of their innocence and the complainant\u27s lack of credibility. It then became a story of actual innocence. The prosecution\u27s case fell apart in the face of vigorous defense work and the North Carolina Attorney General intervened and, following an independent investigation, declared the three indicted lacrosse players to be actually innocent. It then became about prosecutorial ethics, when the North Carolina Bar instituted an ethics complaint, resulting in the disbarment of Durham County District Attorney Mike Nifong for his actions in misleading the court, withholding exculpatory evidence, and making public statements intended to prejudice the targets of the investigation.\u27 Finally, it became a story about the role of civil litigation to remedy unconstitutional and tortuous misconduct in the criminal justice system. Forty-one lacrosse players have filed two separate lawsuits against various government actors, Duke University, and Duke officials. Underlying each phase are issues of race, class, gender, the role of athletics, the role and obligations of university faculty, the role and obligations of university administrators, and the role of the mass media in covering the criminal justice system and how press coverage contributed to the problems in this controvers
Effects of Molybdenum Supplementation on Performance of Forageâfed SteersReceiving Highâsulfur Water
There has been onâgoing research in the area of the consumption of highâsulfur (S) water by steers grazing rangeland as well as forageâfed steers in a feedlot setting. During the summer of 2009, a trial was conducted on the effects of highâS water in finishing steers supplemented with molybdenum (Mo). The main purpose of the research was to gather data that may aid in the formulation of a supplement to counteract the negative effects of highâS water consumed by ruminant livestock species in areas where sulfur concentration in water sources is a risk to animal health and performance. The specific focus of this trial was to determine whether the feeding of supplemental Mo would improve animal health and performance by decreasing the formation of hydrogen sulfide gas (H2S) in the rumen. Yearling steers (n=96) were used for a 56âd trial. The trial consisted of 3 treatment groups; a lowâS water group and two highâS water groups. One highâS water treatment group received the same pellet that the lowâS group was given and the other highâS water treatment group received a pellet with supplemental Mo included. Rumen gas cap H2S was collected on d â1, 29 and 57. Weights were recorded on d â2, â1, 29, 56 and 57. There were no differences between treatments in water intake (P= 0.719), but feed intake was reduced in the steers receiving the supplemental Mo (P \u3c 0.001). There was a significant difference in ruminal H2S due to treatment (P= 0.014), with higher ruminal H2S in the steers receiving the supplemental Mo. Steers receiving the Mo supplement had lower ADG than steers in the other treatments (P= 0.009). Throughout the duration of the trial, two steers were removed from the trial due to advanced symptoms of sulfurâinduced PEM (sPEM) from the highâS treatment with no supplemental M
Investigation of Single Boron Acceptors at the Cleaved Si:B (111) Surface
The cleaved and (2 x 1) reconstructed (111) surface of p-type Si is
investigated by scanning tunneling microscopy (STM). Single B acceptors are
identified due to their characteristic voltage-dependent contrast which is
explained by a local energetic shift of the electronic density of states caused
by the Coulomb potential of the negatively charged acceptor. In addition,
detailed analysis of the STM images shows that apparently one orbital is
missing at the B site at sample voltages of 0.4 - 0.6 V, corresponding to the
absence of a localized dangling-bond state. Scanning tunneling spectroscopy
confirms a strongly altered density of states at the B atom due to the
different electronic structure of B compared to Si.Comment: 6 pages, 7 figure

BIODESULF(TM), A Novel Biological Technology for the Removal of H2S From Sour Natural Gas
The state-of-the-art technologies for the removal of sulfur compounds from Sour Natural Gas (SNG) are not cost-effective when scaled down to approximately 2-5 MMSCFD. At the same time, the SNG Production is increasing at 3-6 TCF/Yr and -78 TCF potential reserves are also sour. Assuming only 3% treatment of this potential SNG market is for small volume processing, the potential U.S. Market is worth 0.28 billion. Therefore, the Gas Processing Industry is seeking novel, cost-effective, environmentally compatible and operator friendly technologies applicable to the small volume producers in the range of less than 1 MMSCFD to - 5 MMSCFD. A novel biological process, BIODESTJLFTM (patent pending), developed at ARCTECH removes H{sub 2}S and other sulfur contaminants that make the Natural Gas Sour. The removal is accomplished by utilizing an adapted mixed microbial culture (consortium). A variety of anaerobic microbial consortia from ARCTECH`s Microbial Culture Collection were grown and tested for removal of H{sub 2}S. One of these consortia, termed SS-11 was found to be particularly effective. Utilizing the SS-11 consortium, a process has been developed on a laboratory-scale to remove sulfur species from Sour Natural Gas at well head production pressures and temperatures. The process has been independently evaluated and found to be promising in effectively removing H{sub 2}S and other sulfur species cost effectively
