Conservation Biology, EarlyView.Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Pensando - Revista de Filosofia, 2017 Não parece haver, ao menos num primeiro olhar, qualquer ponto de convergência entre a literatura de Lampedusa e a filosofia de Kierkegaard. Contudo, com um pouco mais de investigação, tal percepção revela-se falsa. Ambos os autores se situam no século XIX e, nesse sentido, há forte conexão entre ambos a partir de uma análise histórica, filosófica e ...

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, EarlyView.Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Oral interaction plays a facilitative role in second language acquisition. While numerous studies have explored adult learners’ interactions, research that has examined young learners’ interactions, especially among Chinese as a second language learners (CSLs), is lacking. This study focused on CSLs and Chinese‐speaking students (CSSs) in Hong

Gaoya dianqi, 2005 研制了宽带和窄带两种超高频外置天线传感器,两种传感器增益均大于1,驻波比在其有效带宽范围内均小于2,均能用于GIS局部放电超高频检测。设计了高性能放大器和半分布参数超高频滤波器,工作频带为300～1000MHz,完全覆盖了两种传感器的工作频带。性能测试表明,传感器和滤波放大器性能优良,频率匹配,能满足超高频信号检测预处理的要求。通过对绝缘子表面金属污染缺陷产生的局部放电信号进行检测研究表明,超高频检测系统能够检测到超高频段微弱的局部放电信号,并能抑制低频段干扰,为后续模式识别的研究打下了基础。
