PURPOSE: To study the frequency of cervical spine dysfunction (CCD) signs and symptoms in subjects with and without temporomandibular disorder (TMD) and to assess the craniocervical posture influence on TMD and CCD coexistence. METHODS: Participants were 71 women (19 to 35 years), assessed about TMD presence; 34 constituted the TMD group (G1) and 37 comprised the group without TMD (G2). The CCD was evaluated through the Craniocervical Dysfunction Index and the Cervical Mobility Index. Subjects were also questioned about cervical pain. Craniocervical posture was assessed by cephalometric analysis. RESULTS: There was no difference in the craniocervical posture between groups. G2 presented more mild CCD frequency and less moderate and severe CCD frequency (p=0.01). G1 presented higher percentage of pain during movements (p=0.03) and pain during cervical muscles palpation (p=0.01) compared to G2. Most of the TMD patients (88.24%) related cervical pain with significant difference when compared to G2 (p=0.00). CONCLUSION: Craniocervical posture assessment showed no difference between groups, suggesting that postural alterations could be more related to the CCD. Presence of TMD resulted in higher frequency of cervical pain symptom. Thus the coexistence of CCD and TMD signs and symptoms appear to be more related to the common innervations of the trigeminocervical complex and hyperalgesia of the TMD patients than to craniocervical posture deviations.

Posture Assessment

Resumo Objetivos Identificar aspectos biomecânicos de risco para síndrome do manguito rotador (SMR) e analisar os fatores associados aos quadros encontrados entre trabalhadores de montagem de caminhões. Materiais e métodos Estudo transversal analítico em montadora de caminhões da Grande São Paulo no ano de 2013. Foi realizada avaliação ergonômica dos postos de trabalho com aplicação da ferramenta OWAS (Ovako Working posture Assessment System). Entre os 79 funcionários que participaram da pesquisa, foram considerados casos de SMR quando havia relato de queixas álgicas nos ombros na última semana e a manobra semiológica específica era positiva. Resultados Nove dos 12 postos de trabalho analisados requerem biomecânica de elevação de membros superiores acima do nível dos ombros. A ferramenta ergonômica indica a necessidade de medidas corretivas imediatas em cinco postos de trabalho. O perfil dos participantes era: sexo masculino, idade média de 35 anos e tempo médio de trabalho na empresa de 7,83 anos. A SMR foi detectada em 17,7% dos participantes. O desfecho esteve associado à idade e ao tempo de trabalho na empresa. Conclusão A atividade de trabalho pode levar ao desenvolvimento de SMR em trabalhadores. Os mais velhos e os com maior tempo de trabalho na empresa são os grupos que devem ser acompanhados de forma mais frequente a fim de diagnóstico precoce de casos.

ABSTRACTThis paper describes a new concept for a high-temperature, electrodeless melter for vitrifying radioactive wastes. Based on the principles of induction heating, it circumvents a number of difficulties associated with existing technology. The melter can operate at higher temperatures (1500–2000°C vs 1150°C), allowing for a higher quality, more durable glass which reduces the long-term leaching rate. Higher processing temperatures also enable conversion from borosilicate to high-silica glass which can accommodate 2 to 3 times as much radioactive waste, potentially halving the ultimate required long-term disposal space. Finally, with high temperatures, conversion of nuclear waste into ceramics can also be considered. This too leads to higher waste loading and the reduction of repository space. The melter is toroidal, linked by an iron core transformer that allows efficient electrical operation even at 60 Hz. One-dimensional electrical and thermal analyses are presented.

Shs Method

This paper researched the fabrication of perovskite synrock by self-propagating high temperature synthesis (SHS) and the characterization of the products. This synthesis process is simpler, the fabricated synrock can immobilize waste loading up to 35wt% SrO with satisfied physical properties (density>4.2g•cm-3, open porosity<0.2%, Leach rate<1.0 g•m-2•d-1). The structure analyses by XRD and SEM/EDS show that the major phase is perovskite which well agrees with the design. It proves that SHS offer a suitable Sr-waste synroc which is favorable for geological disposal.
