A proposal to measure polarization in pp, pi- p and pi+ p elastic scattering at 50, 100, and 150 GeV/c at the National Accelerator Laboratory

The authors propose to measure the polarization parameter in pp, {pi}{sup -}p, and {pi}{sup +}p scattering at incident momenta of 50, 100, and 150 GeV/c over the range 0.15 {le} -t {le} 1.5 (GeV/c){sup 2}. The apparatus consists of a polarized proton target, two spectrometer arms which determine the angles and momenta of both outgoing particles, and an on-line computer. The detectors are designed to operate at incident beam rates of up to 10{sup 8} beam particles/pulse. They anticipate an error in the polarization parameter P of .005 {le} {Delta}P {le} .01 over the range .15 {le} -t {le} .8 (GeV/c){sup 2} in 100 shifts of data taking and background studies

Quasielastic axial-vector mass from experiments on neutrino-nucleus scattering

We analyze available experimental data on the total and differential charged-current cross sections for quasielastic neutrino and antineutrino scattering off nucleons, measured with a variety of nuclear targets in the accelerator experiments at ANL, BNL, FNAL, CERN, and IHEP, dating from the end of sixties to the present day. The data are used to adjust the poorly known value of the axial-vector mass of the nucleon.Comment: 27 pages, 19 figures.

Understanding renal posttransplantation anemia in the pediatric population

Advances in renal transplantation management have proven to be beneficial in improving graft and patient survival. One of the properties of a well-functioning renal allograft is the secretion of adequate amounts of the hormone erythropoietin to stimulate erythropoiesis. Posttransplantation anemia (PTA) may occur at any point in time following transplantation, and the cause is multifactoral. Much of our understanding of PTA is based on studies of adult transplant recipients. The limited number of studies that have been reported on pediatric renal transplant patients appear to indicate that PTA is prevalent in this patient population. Erythropoietin deficiency or resistance is commonly associated with iron deficiency. An understanding of the risk factors, pathophysiology and management of PTA in the pediatric renal transplant population may provide guidelines for clinicians and researchers in the pursuit of larger prospective randomized control studies aimed at improving our limited knowledge of PTA. Recognition of PTA through regular screening and evaluation of the multiple factors that may contribute to its development are recommended after transplantation

Medicina complementar no SUS: práticas integrativas sob a luz da Antropologia médica

O artigo examina a contribuição da Medicina complementar para o Sistema Único de Saúde - SUS em um novo contexto de institucionalização. A reflexão analisa políticas oficiais de instituições sanitárias, como a OMS e o Ministério da Saúde, além da literatura especializada no tema. As práticas integrativas e complementares no SUS, em meio a um itinerário de crescente legitimação, valorizam recursos e métodos não biomédicos relativos ao processo saúde/doença/cura, enriquecem estratégias diagnóstico/terapêuticas e podem favorecer o pluralismo médico no Brasil. Desse modo, o atual sistema público de saúde transporta para seu interior outros saberes e racionalidades de base tradicional, que passam a conviver com a lógica e os serviços convencionais da biomedicina. O artigo acentua a discussão antropológica sobre integralidade em políticas públicas de saúde, com ênfase nos aspectos sociais, simbólicos e culturais que as realidades sanitárias necessariamente abrigam. Em conclusão, chama-se a atenção para a necessidade de aprofundamento do conceito de integralidade, bem como para o enfrentamento dos desafios práticos que sua implantação requer.The article examines the contribution of Complementary Medicine to Sistema Único de Saúde (SUS - Brazil's National Health System) in a new institutionalization context. The reflection analyzes official policies of health institutions such as the WHO and the Ministry of Health, in addition to the specialized literature on the subject. The integrative and complementary practices within the SUS, in the midst of a path of increasing legitimacy, value non-biomedical resources and methods related to the health/disease/cure process, enrich diagnostic/therapeutic strategies, and may encourage medical pluralism in Brazil. Thus, the current public health system transports into its interior other traditional knowledge and rationalities, which start to coexist with the logic and conventional services of biomedicine. The article stresses the anthropological discussion about integrality in public health policies, with emphasis on the social, symbolic, and cultural aspects that the sanitary realities necessarily shelter. In conclusion, attention is drawn to the need to investigate the integrality concept, as well as to face the practical challenges its implantation requires
