The Physical Processes of CME/ICME Evolution

As observed in Thomson-scattered white light, coronal mass ejections (CMEs) are manifest as large-scale expulsions of plasma magnetically driven from the corona in the most energetic eruptions from the Sun. It remains a tantalizing mystery as to how these erupting magnetic fields evolve to form the complex structures we observe in the solar wind at Earth. Here, we strive to provide a fresh perspective on the post-eruption and interplanetary evolution of CMEs, focusing on the physical processes that define the many complex interactions of the ejected plasma with its surroundings as it departs the corona and propagates through the heliosphere. We summarize the ways CMEs and their interplanetary CMEs (ICMEs) are rotated, reconfigured, deformed, deflected, decelerated and disguised during their journey through the solar wind. This study then leads to consideration of how structures originating in coronal eruptions can be connected to their far removed interplanetary counterparts. Given that ICMEs are the drivers of most geomagnetic storms (and the sole driver of extreme storms), this work provides a guide to the processes that must be considered in making space weather forecasts from remote observations of the corona.Peer reviewe

Burkholderia pseudomallei: a case report of a human infection in Ceará, Brazil Burkholderia pseudomallei: infecção humana no Ceará, Brasil

Burkholderia pseudomallei has rarely been isolated from environmental and clinical specimens in South America, particularly, in Brazil. This report describes a case of melioidosis with fulminant sepsis in a 10 year old boy, from rural area, in Tejuçuoca, State of Ceará, Brazil. Blood samples were positive and, through the analysis of results from biochemical tests and of drugs susceptibility profile, identified this gram-negative bacillus as B. pseudomallei. The contamination source remains obscure in this case, as soil and water tanks samples submitted to microbiological analyses did not indicate the presence of B. pseudomallei.<br>O isolamento de Burkholderia pseudomallei, de meio ambiente e de espécimes clínicos, foi raramente registrado na América do Sul, particularmente no Brasil. Este relato descreve o caso de melioidose em um paciente de 10 anos de idade, de área rural do estado do Ceará (Tejuçuoca). As hemoculturas foram positivas e as análises dos testes bioquímicos e de susceptibilidade aos antimicrobianos do isolado foram indicativos para a identificação de B. pseudomallei. A fonte de contaminação foi obscura, uma vez que as análises microbiológicas de solo e água no tanque foram negativas

INTEGRATING COMMUNITY MENTAL HEALTH SERVICES INTO LOCAL JAILS: A POLICY PERSPECTIVE

Across t h e nation, the number o f mentally ill inmates in local jails has increased over the past decade. Moreover, mentally ill inmates are not typically receiving adequate services from either the jail or mental health service systems. In response to the problem, several jurisdictions are attempting to utilize community mental health (CMH) services to provide treatment for these inmates. This paper discusses organizational problems inherent to integrating CMH services into jails and recommends approaches for dealing with those problems. Much of the information and thinking in this paper is based upon the recent experience of the authors with the Michigan Department of Mental Health and local jails as trainers and consultants in integrating CMH workers into jail settings.
