Lunar surface magnetic fields and their interaction with the solar wind: results from lunar prospector   总被引：1，自引：0，他引：1  

RP Lin  DL Mitchell  DW Curtis  KA Anderson  CW Carlson  J McFadden  MH Acuna  LL Hood  A Binder 《Science (New York, N.Y.)》1998,281(5382):1480-1484

The magnetometer and electron reflectometer experiment on the Lunar Prospector spacecraft has obtained maps of lunar crustal magnetic fields and observed the interaction between the solar wind and regions of strong crustal magnetic fields at high selenographic latitude (30 degreesS to 80 degreesS) and low ( approximately 100 kilometers) altitude. Electron reflection maps of the regions antipodal to the Imbrium and Serenitatis impact basins, extending to 80 degreesS latitude, show that crustal magnetic fields fill most of the antipodal zones of those basins. This finding provides further evidence for the hypothesis that basin-forming impacts result in magnetization of the lunar crust at their antipodes. The crustal magnetic fields of the Imbrium antipode region are strong enough to deflect the solar wind and form a miniature (100 to several hundred kilometers across) magnetosphere, magnetosheath, and bow shock system.  相似文献   

Gastrointestinal small-cell lymphoma with gall bladder involvement in a cat     

Baxter KJ  Hill RC  Parfitt SL  Berry CR  Heskett TW  Sheppard BJ 《Journal of Feline Medicine and Surgery》2012,14(4):267-271

A 13-year-old female spayed domestic shorthair cat presented for investigation of decreased appetite and increased serum liver enzyme concentrations. An abdominal ultrasound revealed multiple sessile hyperechoic structures along the luminal aspect of the gall bladder wall and a mildly enlarged liver with hyperechoic nodules. Cholecystectomy was performed and biopsies were obtained by laparotomy. Histopathologic examination with immunohistochemistry was consistent with a diagnosis of small-cell lymphoma of T cells within the gall bladder, liver and small intestine. Clonality testing confirmed the diagnosis. The cat remains clinically stable 23 months after institution of treatment with prednisolone, chlorambucil and ursodeoxycholic acid. This is the first report of small-cell lymphoma in the gall bladder of a cat.  相似文献   

Knowledge and attitudes of Australian livestock producers concerning biosecurity practices     

CC Paquette  KA Schemann  MP Ward 《Australian veterinary journal》2020,98(11):533-545

Biosecurity risks are a major threat to the profitability of the industry as well as impacting human and animal health. Livestock producers play a crucial role in biosecurity as the first to notice changes in the health or productivity of their stock and are generally responsible for implementing protective measures. However, uptake of biosecurity measures by producers is variable. We critically appraised the current literature regarding biosecurity practices in Australian livestock industries and highlight aspects that are well understood as well as those where further research or information is needed. Findings from 12 cross-sectional studies suggest that Australian producers' knowledge of biosecurity methods and importance might have a positive influence on their willingness to implement or incorporate biosecurity practices. There is moderate evidence supportive of biosecurity being well understood by livestock producers across Australia. Barriers to producers using biosecurity practices included lack of information or communication from agricultural, veterinary or government organisations. It was found that larger stock numbers were positively correlated with biosecurity implementation and that producers used veterinarians, government and industry agencies as resources for trusted information.  相似文献

Application of high-resolution melt curve analysis for classification of infectious bronchitis viruses in field specimens     

KA Hewson  GF Browning  JM Devlin  J Ignjatovic  AH Noormohammadi 《Australian veterinary journal》2010,88(10):408-413

Objective A real-time polymerase chain reaction (PCR)/high-resolution melt (HRM) curve analysis protocol was developed in our laboratory to differentiate infectious bronchitis (IB) virus reference strains. In the current study, this method was used to detect and classify IB viruses in field submissions. Procedure Over an 11-month period samples from 40 cases of suspected IB virus were received and 17 submissions were positive for IB virus by polymerase chain reaction. HRM curve analysis classified each strain as subgroup 1, 2 or 3 strain (12 submissions) or a strain that was unable to be classified (5 submissions). The 3′ untranslated region (UTR) and partial S1 gene nucleotide sequences for the 17 IB virus strains were determined and their identity with those of the relative reference strains compared to confirm the classifications generated using the HRM curve analysis. Results Of the 12 IB field viruses classified as subgroup 1, 2, or 3 using HRM curve analysis, the 3′UTR and S1 gene nucleotide sequences had identities ≥99% with the respective subgroup reference strain. Analysis of the 3′ UTR and S1 gene nucleotide sequences for the five IB virus strains that could not be classified indicated that four belonged to one of the subgroups, and one was a potential recombinant strain (between strains from subgroups 2 and 3). A novel recombinant strain was also detected. Conclusion HRM curve analysis can rapidly assign the majority of IB viruses present in field submissions to known subgroups. Importantly, HRM curve analysis also identified variant genotypes that require further investigation.  相似文献

Cost-benefit evaluation of artificial insemination for genetic improvement of wool-producing sheep   总被引：1，自引：0，他引：1  

KA ABBOTT 《Australian veterinary journal》1994,71(11):353-360

SUMMARY The financial costs and benefits associated with the use of artificial insemination (AI) in commercial flocks are evaluated. Benefits are calculated in terms of net present values after summing the discounted value of benefits over 20 years. Two breeding strategies are evaluated. With the first, AI is used to produce flock ewes and wethers. The method is unlikely to be profitable unless high breeding value rams are available for AI programs with fresh semen. With the second, AI is used to produce home-bred rams, which in turn sire flock ewes and wethers. This approach is more likely to be profitable. The cost of AI per lamb weaned from laparoscopic AI programs is about $100. Benefits exceed this cost for rams of very high merit when wool prices are moderate or higher. Flock structure has a significant effect on the benefits. Flocks with low wether retention rates have benefits half that of flocks that retain most wethers to 6 years of age. AI with purchased semen also provides benefits to risk management for owners of commercial flocks who wish to breed their own replacement flock rams.  相似文献   

肉鸡的饲料排出是个复杂的问题     

梁正维  G.D.Butcher  A.H.Nilipour  Eric Heskett 《国外畜牧学(猪与禽)》2001,(2):10-10

“饲料排出” ,或者说得更准确些是未消化饲料从肉鸡的粪中排出 ,一直是时不时听到肉鸡饲养企业报告的一个问题。如今 ,这个问题的发生率和严重程度已经比 1 996年时低了很多 ,当时在谷物连年歉收之后全世界都报告了饲料排出的问题。说肉鸡将未消化的饲料经粪排出体外 ,是因为在粪中可见到很大的玉米颗粒和过量的水分 ,同时见到粪便不成形 ,其颜色为特征性的绿色并带有橙色粘液。受害肉鸡色泽苍白 ,饲料利用率低下 ,体重很轻 ,群体均一度很差。剖检常见受害肉鸡腺胃、肌胃和小肠病变。有趣的是在有些饲喂稻谷的国家 ,比如圭亚那 ,则未见这一…  相似文献
