摘要： The intensification of farm management practices on grasslands has reduced the abundance of many species of animals. Mowing, a procedure essential to the continuing existence of farmland meadows, inevitably causes mortality among the animals inhabiting them, especially invertebrates, and exposes sites where white storks Ciconia ciconia can forage conveniently and more efficiently. We studied the foraging activities of storks on meadows being mown and compared these with the birds' foraging patterns on unmown meadows and meadows cleared of hay in the extensively managed farming landscape of east-central Poland. Foraging success was deemed to be the capture of a prey item as manifested by the stork raising its head and swallowing prey item. The storks' foraging success on meadows being mown was roughly the same as on unmown meadows but was significantly lower than on those cleared of hay. The number of steps taken by storks - a measure of the energy they expended on foraging - was far higher on meadows being mown than on unmown ones. Even so, on meadows being mown, storks caught proportionately more vertebrates (voles) (5.2% of all prey items) than on cleared meadows (1.4%) and unmown meadows (0.2%). The fact that vertebrates are considerably energy-richer than invertebrates was probably the main reason why storks were attracted to forage on meadows being mown, even though their foraging efficiency was not particularly high - an aspect emphasised in the literature. The sequential (asynchronous) mowing of the highly fragmented, semi-natural meadows in this part of Poland coincides with the time when storks are feeding their young. This is probably a key aspect governing the high density of this species.

摘要： 随着国民经济的快速发展,为了满足对电力的更高需求,需要充分保证电力系统的安全运营以及有效供给.现如今,国家电网公司对电网的投资正在不断加大,电网基建投资也需要充分保证科学性和规范性,并要有效开展基建管理工作.与此同时,相关电网企业也对基建管理的理论、体制机制和方法提出了更为明确的要求,需要严格管理电网工程成本其他费用.相关电网公司通过应用信息系统,可以使工程标准成本的日常管理工作得到强化,并能够使业务前端管理得到促进,从而精细化的管控电网工程其他费用.本文针对精细化管理在电网工程其他费用中的运用进行分析,介绍了电网工程其他费用管控现状,探讨了电网工程其他费用精细化管控模式的构建措施,并提出具体的精细化管理对策,希望能够为相关工作人员起到一些参考和借鉴.

关键词： 时效中断   起诉   其他中断事由   中断效力  

摘要： 中断事由之起诉要件与程序法之起诉要件非采相同标准,起诉被不予受理、驳回或者申请撤诉、按撤诉处理,亦有可能构成中断事由。诉讼是否作出实体判决,对中断事由认定及时效期间重新计算存在影响。第195条第4项新增兜底条款的意义在于,对司法解释扩张解释中断事由予以承认。申请确认调解协议的效力、申请参与分配、申请实现担保物权、诉讼中的其他抗辩等情形,也应认定为中断事由。诉讼外请求和义务承认之中断时点是意思通知生效之日,重新计算时点是"中断时";起诉之中断时点是"提交起诉状或者口头起诉之日",重新计算时点是"有关程序终结时"。时效中断效力原则上仅具相对性,例外情形下具有牵连性。

摘要： 本文研究捕食者具有Allee效应和其他食物来源的Leslie-Gower模型的动力学性质。我们讨论了边界平衡点和正平衡点存在的条件和稳定性。说明了较大的Allee效应会破坏系统的稳定性。当捕食者具有其他食物来源时,系统的动力学性质会变得更加复杂,也就是捕食者具有其他食物来源可能会破坏系统的稳定性。最后通过数值模拟,发现系统会经历Hopf分支并产生极限环。

摘要： Objectives: Investigate trends over time and predictors of malignancies among children and young people with HIV. Design: Pooled data from 17 cohorts in 15 countries across Europe and Thailand. Methods: Individuals diagnosed with HIV and presenting to paediatric care less than 18 years of age were included. Time at risk began at birth for children with documented vertically acquired HIV, and from first HIV-care visit for others. Children were followed until death, loss-to-follow-up, or last visit in paediatric or adult care (where data after transfer to adult care were available). Rates of reported malignancies were calculated overall and for AIDS-defining malignancies (ADM) and non-AIDS-defining malignancies (NADM) separately. Risk factors for any malignancy were explored using Poisson regression, and for mortality following a malignancy diagnosis using Cox regression. Results: Among 9632 individuals included, 140 (1.5%) were ever diagnosed with a malignancy, of which 112 (80%) were ADM. Overall, the rate of any malignancy was 1.18 per 1000 person-years;the rate of ADM decreased over time whereas the rate of NADM increased. Male sex, being from a European cohort, vertically acquired HIV, current severe immunosuppression, current viral load greater than 400 copies/ml, older age, and, for those not on treatment, earlier calendar year, were risk factors for a malignancy diagnosis. Fifty-eight (41%) individuals with a malignancy died, a median 2.4 months (IQR 0.6-8.8) after malignancy diagnosis. Conclusion: The rate of ADM has declined since widespread availability of combination ART, although of NADM, there was a small increase. Mortality following a malignancy was high, warranting further investigation.
