Abstract: objective: during the second half of 1996, the municipalities of londrina and curitiba (state of paraná, brazil) included haemophilus influenzae type b (hib) vaccine into their routine vaccination regimen, approximately 30 months before its introduction into the national immunization program. the present study aimed at verifying the incidence of meningitis caused by hib among children in londrina, curitiba, and in the remaining municipalities of the state, before and after the introduction of this vaccine into the immunization program. methods: an observational and retrospective study was carried out. the study included all cases of haemophilus influenzae type b meningitis recorded by the epidemiological surveillance system in londrina and by the state of paraná health secretariat between 1992 and 1999 among children aged less than 5 years. the incidence rates of hib meningitis were calculated per 100,000 children aged less than five years. results: after the introduction of hib vaccine, an important reduction in the incidence rate of haemophilus influenzae type b meningitis was observed in londrina (from 23.91 in 1996 to 2.79 in 1999). a similar decrease was observed in curitiba. in the remaining localities of the state, which had not introduced the vaccine till mid-1999, the incidence rate remained almost unchanged. conclusion: regular vaccination against hib was effective in reducing the incidence rate of meningitis amongst children younger than five years in londrina and curitiba. in order to maintain this low incidence rate, adequate vaccination coverage and strict epidemiological surveillance should be guaranteed.
具有任意非线性输入的鲁棒模型参考自适应控制
余文, M.De la Sen, 柴天佑
自动化学报 , 1997,
Abstract: ?提出了一种分析具有任意非线性输入的模型参考自适应(MRAC)的新方法,它不要求对象是稳定的,允许系统存在未建模动态和有界扰动.同时给出了一种提高非线性输入自适应系统特性的补偿方案,它通过在控制律中引入跟踪误差,可以提高系统的暂态及稳态精度,而又不破坏MRAC系统的收敛特性.

Anais da Escola Superior de Agricultura Luiz de Queiroz , 1983, DOI: 10.1590/S0071-12761983000100031
Abstract: this experiment was carried out to study the effects of the temperatures of 14, 21 and 28°c on germination of three cultivars of vigna unguiculata, phaseolus vulgaris and glycine max. the seeds where germinated on petri dishes provided with cotton and filter paper, maintained in incubator with high humidity. the petri dishes were maintained under controlled temperature conditions. higher germination was observed at 21°c in relation to temperatures of 14 and 28°c, for vigna, bean and soybean cultivars. best germination were showed by 'carioca' and 'goiano precoce' beans,followed by 'rosinha' bean, 'epace 1' vigna and 'davis' soybean at 21°c. vigna cultivars adapted to high temperatures presented problems for germination at 14°c. normaly velocity of hypocotyl emergence was lower tham velocity of radicle emergence.

自动化学报 , 1997,
Abstract: This paper presents a new analysis method for model reference adaptive control (MRAC) with arbitrary bounded input nonlinearities, which does not require the stability of plants. The plant can have unmodeled dynamics and bounded disturbances. A new modified MRAC scheme is also proposed to improve the transient and steady state performances. The output error is used directly in the control law to generate a modified control signal to compensate possible bad performances of the robust adaptive controllers, and the ideal asymptotic properties of MRAC is not destroyed.

Abstract: existe la necesidad de reforzar la capacidad regional para la vigilancia de las enfermedades crónicas en las américas. los objetivos de este artículo son 1) ofrecer nuestro apoyo decidido a favor de la vigilancia de las enfermedades crónicas, 2) presentar una revisión descriptiva y un resumen de las actividades de vigilancia y los problemas en torno a las mismas en las américas, 3) confeccionar una lista de recursos y fuentes de consulta para obtener más información, y 4) ofrecer unas recomendaciones para reforzar la capacidad regional. este artículo se basa en una revisión personal de informes, sitios de internet y apuntes personales procedentes de diversos proyectos, reuniones y actividades relacionados con la vigilancia de las enfermedades crónicas en las américas, y en un análisis a profundidad de los materiales recopilados. se ha determinado que las agencias sanitarias internacionales, los gobiernos de diversos países, las organizaciones no gubernamentales y los profesionales de la sanidad pública han dedicado grandes esfuerzos a la construcción y al desarrollo de las capacidades de vigilancia de las enfermedades crónicas en la región. para seguir apoyando el aumento de dichas capacidades, se hace necesario establecer una red de redes (una metarred) cuya misión debería ser la vigilancia de la vigilancia. siete aspectos importantes para el aumento de esta capacidad son la estrategia, la colaboración, la información, la educación, la novedad, la comunicación, y la evaluación.

Abstract: The naked mole-rat (Heterocephalus glaber) is a long-lived, cancer resistant rodent and there is a great interest in identifying the adaptations responsible for these and other of its unique traits. We employed RNA sequencing to compare liver gene expression profiles between naked mole-rats and wild-derived mice. Our results indicate that genes associated with oxidoreduction and mitochondria were expressed at higher relative levels in naked mole-rats. The largest effect is nearly 300-fold higher expression of epithelial cell adhesion molecule (Epcam), a tumour-associated protein. Also of interest are the protease inhibitor, alpha2-macroglobulin (A2m), and the mitochondrial complex II subunit Sdhc, both ageing-related genes found strongly over-expressed in the naked mole-rat. These results hint at possible candidates for specifying species differences in ageing and cancer, and in particular suggest complex alterations in mitochondrial and oxidation reduction pathways in the naked mole-rat. Our differential gene expression analysis obviated the need for a reference naked mole-rat genome by employing a combination of Illumina/Solexa and 454 platforms for transcriptome sequencing and assembling transcriptome contigs of the non-sequenced species. Overall, our work provides new research foci and methods for studying the naked mole-rat's fascinating characteristics.
