Plantations with fast-growing species play a crucial role in reducing global warming and have great carbon capture potential. Therefore, determining optimal management strategies is challenge the of forest plantations to achieve maximum rate. The objective this work determine rotation that maximize plantations. By evaluating an ecological control problem, presents method manages by planning act...

The article describes the causes of occurrence and forms geomechanical processes manifestation in surrounding coal-rock massif mine workings supported by anchor support. Based on long-term field observations, six typical deformations have been established. Design solutions to strengthen support or complete reinforcement damaged sections during local felling developed. They include: installation...

Perceptual load theory successfully replaced the early vs. late selection debate by appealing to adaptive control over the efficiency of selective attention. Early selection is observed unless perceptual load (p-Load) is sufficiently low to grant attentional "spill-over" to task-irrelevant stimuli. Many studies exploring load theory have used limited display durations that perhaps impose artifi...

In this paper we will show that Ikema, a dialect of Miyako Ryukyuan, has a three-tone system, where three tonal classes, Types A, B, and C, are lexically distinguished, contra the previous studies which have claimed that it has a two-tone system. The results of our quantitative analysis of production data also revealed that Type A words are remarkably small in number, indicating that Type A wor...
