Seismic performance assessment of a timber log house

The current work presents a full scale shaking table test conducted on a twostoreyed timber log house, designed according to the state of the art on timber engineering. The test was performed within the framework of the SERIES Project “Multi-storey timber buildings” at LNEC, Lisbon, Portugal. Several tests and studies have been carried out by the University of Minho to characterize the behavior of the different components (logs, walls, slabs, connections, etc.) of log houses in the past few years for the European Technical Approval (ETA) of this construction system. The main results of the shaking table test are presented along with the preliminary analysis of the overall behavior of the log house. The analysis was carried out based on the shaking table tests and on a numerical model developed to estimate the main seismic parameters using the data obtained from the different individual studies on each component of the construction system performed within the framework of the ETA

Seismic analysis of a 2-storey log house

The current paper deals with the analysis of the results yielded by a series of tests performed to evaluate the seismic behaviour of a model log construction. The study was based on an experimental investigation performed to improve the existing knowledge on log houses subject to seismic events. The main part of the experimental work is based on a full scale shaking table test, conducted on a two-storey log house designed by the Portuguese company Rusticasa® in compliance with design rules for timber buildings. The test was performed by the University of Minho within the framework of the SERIES Project ‘Multi-storey timber buildings’ and was coordinated by the University of Trento, at LNEC, Lisbon, Portugal. The geometry of the specimen, the design of the test, the setup and the instrumentation layout are first presented in this paper. The test procedure was conducted in stages with maximum accelerations (bi-directional) of 0.07g, 0.28g and 0.5g. The experimental results of each test have been analyzed and the resultant values of inter-storey drift, wall slippage and uplift measurements, shear deformations and hold-down forces measured are presented. Most importantly, the dynamic properties (fundamental period and mode shapes) of the system have been determined

Efficacy Of Electroacupuncture For Myofascial Pain In The Upper Trapezius Muscle: A Case Series.

Electroacupunture (EA) includes the passage of an electrical current through the acupuncture needle and is commonly used for pain relief. To evaluate the EA treatment effects for myofascial pain in the upper trapezius muscle. Twenty women aged ranging from 18 to 40 years (mean=24.95; SD=5.88 years), with a body mass index ranging from 19 to 25 kg/m2 (mean=22.33; SD=0.56 kg/m2), with regular menstrual cycles controlled by oral contraceptive, local or referred pain for more than six months and at least one myofascial trigger point in the upper trapezius participated in this study. The participants received a total of nine EA sessions over five weeks. The needles were inserted at the accupoints GB20, GB21, LV3, LI4, and at ashi points. A mixed current of 2 Hz and 100 Hz was applied alternatively every 5 seconds for 30 minutes. The outcomes were pain intensity measured by the visual analogue scale (VAS), pressure pain threshold (PPT) measured by an algometer, electromyography (EMG) and quality of life measured by the SF-36 questionnaire. Inter-occurrences between sessions were monitored. Paired t-test, Wilcoxon test, and repeated measure analysis of variance (ANOVA) having Tukey-Kramer as post-hoc tests were used. Significant improvement in pain intensity and in PPT occurred after treatment (P<0.0001). EMG of the right trapezius during contraction increased significantly, suggesting muscle function enhancement; the quality of life improved, related to physical components of the SF-36 (P<0.05). The EA showed to be a reliable method for myofascial pain relief. Large randomized blinded controlled trials might be carried out to confirm these results.

The Availability Of Full Match Sibling Donors And Feasibility Of Allogeneic Bone Marrow Transplantation In Brazil.

The feasibility of allogeneic bone marrow transplantation (alloBMT) in a developing country has not yet been demonstrated. Many adverse factors including social and economic limitations may reduce the overall results of this complex and expensive procedure. Our objective was to characterize the most important clinical, social and economic features of candidates for transplantation and their potential donors as well as the influence of these factors on overall survival in a retrospective and exploratory analysis at a university hospital. From July 1993 to July 2001, candidates for BMT were referred to the Bone Marrow Transplantation Unit by Hematology and Oncology Centers from several regions of Brazil. A total of 1138 patients were referred to us as candidates for alloBMT. Median age was 25 years (range: 2 months-60 years), 684 (60.1%) were males and 454 (39.9%) were females. The clinical indications were severe aplastic anemia and hematological malignancies. From the total of 1138 patients, 923 had HLA-typing; 497/923 (53.8%) candidates had full match donors; 352/1138 (30.8%) were eligible for alloBMT. Only 235 of 352 (66.7%) were transplanted. Schooling was 1st to 8th grade for 123/235 (52.3%); monthly family income ranged from US$60 (7$400 (36%). Overall survival for patients with chronic myeloid leukemia, severe aplastic anemia and acute myeloid leukemia was 58, 60 and 30%, respectively. Thus, overall survival rates for the most frequent hematological diseases were similar to those reported in the International Registry, except for acute myeloid leukemia. This descriptive and exploratory analysis suggests the feasibility of alloBMT in a developing country like Brazil.36315-2

OBJETIVO: Avaliar o efeito da EA no tratamento da dor miofascial do músculo trapézio superior. MÉTODOS: Participaram 20 voluntárias com idade entre 18 e 40 anos (24,95±5,88 anos), índice de massa corpórea entre 19 e 25 kg/m2 (22,33±0,56 kg/m2), ciclo menstrual regulado por anticoncepcionais, dor por mais de seis meses no trapézio superior, com pelo menos um ponto gatilho miofascial. Nove sessões de EA foram agendadas, sendo duas por semana. As agulhas foram inseridas nos pontos VB20, VB21, F3, IG4 e em pontos ashi. Aplicou-se uma corrente alternada de 2 Hz e 100 Hz a cada 5 segundos durante 30 minutos. Avaliou-se a eficácia do tratamento quantificando a intensidade da dor com a Escala Visual Analógica (EVA); o limiar de dor à pressão (LDP), com algômetro digital, eletromiografia (EMG) e com o questionário de qualidade de vida SF-36. Possíveis fatores influenciadores entre as sessões foram monitorados. Aplicaram-se os testes t pareado, Wilcoxon e análise de variância com medidas repetidas (ANOVA) e, como post-hoc, o teste de Tukey-Kramer. RESULTADO: Após o tratamento, houve melhora na intensidade da dor e no LDP (P<0,0001). A EMG no trapézio direito, durante a contração, aumentou significativamente, sugerindo melhora da função muscular. A qualidade de vida melhorou considerando os componentes físicos do SF-36 (P<0,05). CONCLUSÃO: A EA mostrou-se confiável no alívio da dor miofascial. Estudos randomizados, cegos e controlados devem ser realizados para confirmar esses resultados.
