Measurement of the electric form factor of the neutron at Q2=0.5 and 1.0 GeV2/c2.

The electric form factor of the neutron was determined from measurements of the d-->(e-->,e'n)p reaction for quasielastic kinematics. Polarized electrons were scattered off a polarized deuterated ammonia (15ND3) target in which the deuteron polarization was perpendicular to the momentum transfer. The scattered electrons were detected in a magnetic spectrometer in coincidence with neutrons in a large solid angle detector. We find G(n)(E)=0.0526+/-0.0033(stat)+/-0.0026(sys) and 0.0454+/-0.0054+/-0.0037 at Q(2)=0.5 and 1.0 (GeV/c)(2), respectively.

Connecting research to combating desertification.

With and without the encouragement of the United Nations Convention to Combat Desertification and its Committee on Science and Technology, scientific research has been undertaken throughout the drylands with the expectation of contributing to combating desertification. Little of this research has been applied in developing countries for its identified purpose. The main reason for this is the limited translation of scientific research into an accessible format for application by development agencies or rural communities.

Connecting community action and science to combat desertification: evaluation of a process.

Combating desertification requires the involvement of many people ranging from communities who experience the effects on a daily basis and scientists attempting to understand the biophysical and socio-economic causes and consequences of desertification, to developers and policy makers on all levels. In many instances, however, the understanding, approaches and actions of these different groups contradict rather than support one another. Over the period 2000 to 2002, a conference process undertaken in southern Africa brought together communities, scientists, and development workers to test the concept that they could connect and work together to combat desertification, given an appropriate framework. The conference was a success, and communities, scientists and developers did exchange experience, knowledge and information. Many lessons were learned, although some pitfalls were experienced. Time, funding, enhanced communication, and good will are the primary ingredients for ensuring that different sectors complement one another in their efforts to combat desertification.

Thirty-seven years of renal transplantation in Oregon.

What we accomplish today as a matter of routine was only imagined by a few 4 decades ago. The journey from that first successful kidney transplant in the 1950s to the multidisciplinary, multiorgan transplant program of today has been a fascinating one. Although we attribute our current results to careful recipient selection and preparation, improvements in organ procurement and preservation, refinement of surgical techniques, improvement in histocompatibility techniques and organ sharing, improvements in immunosuppression and infection control, and careful monitoring of recipients, we and our patients have benefited from significant contributions from our colleagues in government and the law. The 4 that come to mind are the provision of near-universal insurance coverage for end stage renal disease patients in 1972 under the Medicare program, the passage of brain death laws in the mid 1970s, the passage of the National Transplant Act in 1984, and the passage of the Oregon required request law in 1985.

Outcome of renal transplantation at Oregon Health Sciences University: 1982 to 1990.

1. Graft survival increased over the 4 periods between 1982 and 1990 (82-84, 85-86, 87-88, 89-90). The largest increase was in the 89-90 period. 2. Immunosuppression was the key to improved outcome. Cadaveric graft recipients given OKT3 induction plus triple therapy with cyclosporine, azathioprine, and prednisone had significantly better graft survival compared with all other drug combinations. Other factors were improved patient selection, donor management, and outpatient care. 3. Mean serum creatinine levels did not change after cyclosporine was introduced for immunosuppression. The mean serum creatinine level was approximately 1.7 mg/dl at 3 months, 6 months, and 12 months post-transplantation in all 4 periods. 4. Living-related donor outcome was significantly better than cadaveric donor outcome. Half-life for 2-haplotype-matched kidneys was 37 years compared with 12 years for 1-haplotype matches and 6.5 years for cadaveric kidneys. 5. Immediate function and a rejection-free first month were both associated with significantly improved graft survival. 6. Neither peak PRA nor graft number (1st vs regraft) correlated with graft survival. Highly sensitized (PRA greater than 50%) patients and regrafted patients fared as well as less sensitized (PRA less than or equal to 50%) and first graft recipients. This outcome was attributed to a sensitive crossmatch. Because of the crossmatch, highly sensitized patients received much better HLA matches. 7. The incidence of early rejection and delayed function declined significantly between the earliest and latest periods. Improved immunosuppression, donor management, and renal preservation were cited as contributing factors.
