Long-term impacts of harvest residue management on nutrition, growth and productivity of an exotic pine plantation of sub-tropical Australia

Residue retention is an important issue in evaluating the sustainability of production forestry. However, its long-term impacts have not been studied extensively, especially in sub-tropical environments. This study investigated the long-term impact of harvest residue retention on tree nutrition, growth and productivity of a F1 hybrid (Pinus elliottii var. elliottii × Pinus caribaea var. hondurensis) exotic pine plantation in sub-tropical Australia, under three harvest residue management regimes: (1) residue removal, RR0; (2) single residue retention, RR1; and (3) double residue retention, RR2. The experiment, established in 1996, is a randomised complete block design with 4 replicates. Tree growth measurements in this study were carried out at ages 2, 4, 6, 8 and 10 years, while foliar nutrient analyses were carried out at ages 2, 4, 6 and 10 years. Litter production and litter nitrogen (N) and phosphorus (P) measurements were carried out quarterly over a 15-month period between ages 9 and 10 years. Results showed that total tree growth was still greater in residue-retained treatments compared to the RR0 treatment. However, mean annual increments of diameter at breast height (MAID) and basal area (MAIB) declined significantly after age 4 years to about 68-78% at age 10 years. Declining foliar N and P concentrations accounted for 62% (p < 0.05) of the variation of growth rates after age 4 years, and foliar N and P concentrations were either marginal or below critical concentrations. In addition, litter production, and litter N and P contents were not significantly different among the treatments. This study suggests that the impact of residue retention on tree nutrition and growth rates might be limited over a longer period, and that the integration of alternative forest management practices is necessary to sustain the benefits of harvest residues until the end of the rotation.

Ale jaskkot eatnigiella : Alkuperäiskansaliikkeen ja saamen kielen merkitys saamelaisten identiteetille

This study examines the Sámi people and the construction of the Sámi identity and the role of language in the cross-border Sámi movement within the context of the international indigenous movement and discourse between 1962 and 2008. The Sámi movement began as a reaction to state assimilation policies. This led to the birth of indigenous processes strengthening the Sámi cultures and languages. Activities across borders and the ethnopolitical processes in each of the Nordic countries in question also formed the basis of the internationalization of the Sámi people. The discourse on indigenous peoples has grown into a question of human rights, which is examined in different national and international contexts. The study is based on ethnographic data that has been collected via interviews, questionnaires and participant observation with the researched people in different meetings and events. Archive and newsprint material are also used. The approach of the study is auto-ethnographic. The post-colonial theories used in the study strive to destabilize power relations and the distinctions of otherness produced by colonialism, and to reclaim both one's own culture and language in the context of the indigenous movement. A standard model for this type of approach was created by Edward W. Said in his 1978 work Orientalism. The central concepts of the analysis are decolonization, otherness, ethnicity and identity. The dissertation consists of four published articles and an introduction. The subject matter is analyzed on three levels: global, European and Nordic. On the global level, the results demonstrate that the indigenous movement has constructed a new understanding of indigenousness with new rights. International treaties have facilitated the unification of new concepts and rights, such as the right to self-determination and language, also helping in transforming them into rights of the Sámi people on a national level. On the Nordic level, aligning the Sámi culture with indigenous discourse became significant for the process of developing the Sámi identity in the Sámi movement. In this process, the Sámi movement made use of Sámi languages in order to mobilize groups of people and to construct relatedness between different Sámi groups. The realization that one s own language is significant to one's culture has resulted in recreating the vitality, visibility and the legitimation of language in society more generally. The migration of the Sámi people from their traditional territories to increasingly multi-ethnic urban areas alters one's relationship to one's own community as the relationship to cultural traditions changes. Among the urban Sámi, who form a group of ‘new Sáminess’, linguistic discrimination and assimilation continue because of the lack of legislative and other effective language policy measures to promote the learning and use of the Sámi language.

基于DSP的烟支重量控制系统的研究与开发

目前，烟草科技发展的一个重要方向是在改造进口烟机控制设备的基础上，实现烟机核心控制技术的自主知识产权，同时利用当前最新的软件技术和硬件技术不断提高烟机控制技术的发展，促进我国烟机的自动化水平。 本文依托于中科院沈阳自动化研究所自动化装备研究室的项目——PASSIM卷接机组改造。烟支的重量控制是卷接机组决定烟支质量的关键部分，鉴于旧式的PASSIM卷接机组的重量控制系统MAID-N存在着以下不足：没有紧头跟踪功能，体积很大，接口关系复杂，数据传输效率低，电路维修率高，精度较低。因此对重量控制系统的改造采用DSP芯片作为整个系统的核心处理器，缩小了系统体积，提高了系统运行速度和控制精度。基于DSP的烟支重量控制系统实时采集烟支重量信号、计算烟支重量、坏烟剔除，同时还增加了紧头跟踪控制功能。 本文首先介绍了烟支重量控制系统的原理，包括重量控制信号的产生，影响重量控制精度的因素和烟支重量信号的梳理分析。接着介绍了DSP技术，着重于其在烟支重量控制系统中的应用和系统设计中用到的DSP芯片TMS320F2812的结构和外设资源。然后介绍了系统设计流程，包括硬件和软件部分的设计。硬件电路主要是输入信号的滤波处理电路和电机执行部分的硬件设计。软件部分的设计包括基于F2812的AD模块实现过采样算法，烟支重量控制算法实现，紧头跟踪算法设计。软件部分还介绍了系统的通讯设计。最后对新系统在现场运行的情况进行了数据采集，分析表明系统控制精度满足要求。

Image of Niagara Falls n.d.

In 1818 Parkhurst Whitney built stairs leading to the river’s edge at Prospect Point. In 1825 Porter Brother replaced that staircase with a spiral one. In 1844 Whitney started a water powered incline railway there although the staircase was also used until 1890. In 1906 the water wheel was replaced by an electric power plant. There were lower buildings which included Shadow of the Rock which was a concession stand and also rented raincoats to the tourists. This was destroyed by fire and ice in 1892 and replaced by a chalet-style building in 1894-95. On July 6th, 1907 a cable on the incline railway broke. One person was killed and several sustained injuries. An elevator was constructed and it opened in January of 1910. It was condemned in 1954 when water entered the shaft, this was at the time of the collapse of Prospect Point which occurred at 4:50 pm. on July 28, 1954. This photograph was taken prior to 1954. Today the New York State Observation Tower stands at Prospect Point and The Maid of the Mist boat ride is available from the base of the tower. with information from: Niagara Falls Canada: a History by the Kiwanis Club of Stamford, Ontario
