In order to reduce the ecological damage and economic loss caused by mountain torrent disasters in the flooded basin, it’s very important to realize the self-repair of the ecosystem in a short time. Based on the analysis of the causes of mountain torrents, this paper summarizes three main parts of ecological restoration in the river basin, including rainwater storage, Sedimentation and wetland conservation. Taking a research base in Wenling, Zhejiang Province as an example, this paper also discusses the design methods of the landscape inside mountain torrent basins based on ecological restoration from these parts above. Finally, these methods were obtained and applied in design practice, providing more solutions and theoretical references for the ecological restoration design in the future.

This study aims to evaluate the change in flood inundation in the Chitose River basin (CRB), a tributary of the Ishikari River, considering the extreme rainfall impacts and topographic vulnerability. The changing impacts were assessed using a large-ensemble rainfall dataset with a high resolution of 5 km (d4PDF) as input data for the rainfall–runoff–inundation (RRI) model. Additionally, the prediction of time differences between the peak discharge in the Chitose River and peak water levels at the confluence point intersecting the Ishikari River were improved compared to the previous study. Results indicate that due to climatic changes, extreme river floods are expected to increase by 21–24% in the Ishikari River basin (IRB), while flood inundation is expected to be severe and higher in the CRB, with increases of 24.5, 46.5, and 13.8% for the inundation area, inundation volume, and peak inundation depth, respectively. Flood inundation is likely to occur in the CRB downstream area with a frequency of 90–100%. Additionally, the inundation duration is expected to increase by 5–10 h here. Moreover, the short time difference (0–10 h) is predicted to increase significantly in the CRB. This study provides useful information for policymakers to mitigate flood damage in vulnerable areas.

In order to obtain better social and economic benefits, non-traditional materials and technologies must be closely integrated with non-traditional research mode. Traditional studies on materials and techniques are mainly undertaken by engineers of structures and materials, while architects play the role in the application of materials and technologies. Therefore, the application of new materials and technologies shall be inevitably accepted, well acquainted with and proficiently utilized by architects. The three factors that have a major impact on this process are the complexity, differentiation and timeliness, indicating that the application of new materials and technologies is simpler, similar to the application method of traditional materials and technologies and can be learned and mastered by architects in a short time. The hardcore of non-traditional research mode is the close coordination between architects and the engineers of structure and materials, the design methods and technical details that adapt to new materials and technologies.

The Impact

In the environment where glove material is exposed to harmful chemicals, hazards related to faster penetration of dangerous substances into the glove interior may cause microdamage. One of the solutions to overcome this problem is to use the self-healing polymeric materials that can minimize economic loss and accidents in the workplace. The current work aims to present the impact of different types of textile reinforcement on the effectiveness and efficiency of the self-healing process of methyl vinyl silicone rubber containing hybrid molecules with an inorganic silsesquioxane intended for use on all-rubber gloves. Three knitted fabrics with a similar structure and differentiated raw material composition were selected: polyamide, cotton–polyamide, and cotton. Evaluation of the self-healing process of the elastomeric composite to personal protective equipment was performed. For this purpose the assessment of the surface morphology of materials has been performed before and after the self-healing process. The implementation of knitted fabric into the polymeric composite in the tested samples allowed us to obtain the best results in all tests. The studied composite samples exhibited an increased resistance to three types of damage: penetration, abrasion and puncture. The samples also underwent the self-healing processes and regeneration after a proper conditioning period. Thus, the obtained results confirmed the possibility of using tested elastomeric composites in the construction of protective gloves and showed an effectivity of the self-healing process for the long-term usage of that protective equipment.

Abstract Supporting designers is one of the main motivations for design research. However, there is an ongoing debate about the ability of design research to transfer its results, which are often provided in form of design methods, into practice. This article takes the position that the transfer of design methods alone is not an appropriate indicator for assessing the impact of design research by discussing alternative pathways for impacting design practice. Impact is created by different means – first of all through the students that are trained based on the research results including design methods and tools and by the systematic way of thinking they acquired that comes along with being involved with research in this area. Despite having a considerable impact on practice, this article takes the position that the transfer of methods can be improved by moving from cultivating method menageries to facilitating the evolution of method ecosystems. It explains what is understood by a method ecosystem and discusses implications for developing future design methods and for improving existing methods. This paper takes the position that efforts on improving and maturing existing design methods should be raised to satisfy the needs of designers and to truly support them.

<p class="P1">Unexploded sub munitions for military operations posed economic loss and health hazard. The need for unexploded sub munitons to be rendered safe after a certain period of time was of importance to the militaty. In this work, a self-neutralizing sub-component using soft metal penetration principle was developed and incorporated to the existing sub munitions so as to include a self-neutralizing feature in such sub munitions. This study was also conducted to determine the potential to use a steel wire to cut BI-Pb-Sn-Cd alloy at different temperatures (-40 °C～40 °C). The effect of temperature on neutralisation time was evaluated in experiments. The experimental results indicated that the neutralisation time was dependent on temperature of soft metal and decreased with increasing temperature. While BI-Pb-Sn-Cd alloy with thickness of 0.75±0.01 mm and height of 2.40 ±0.02 mm was cut by steel wire with a diameter of 0.12 mm, self-neutrlisation of sub munitions was completed ranging from 1min5s to 143 h 2 min. It was concluded that self-neutralisation based on BI-Pb-Sn-Cd alloy could meet its setting requirements in the battlefield, and its failure rate reached less than 10% at between -40 °C and 40 °C, and the self-neutralisation time could be adjusted by the size of soft metal.</p>

The Law

The law of negligence favours redress for damage to property interests over redress for damage to mere economic interests. The question arises whether this preference can be justified. In endeavouring to answer it, the author surveys existing reasons given by courts and commentators for maintaining a distinction between property and economic interests. Each of these reasons, which collectively focus upon the ‘problematic’ nature of economic losses, is found to be either ad hoe in nature or without substantial explanatory power. However, it is submitted that the distinction is explicable on the basis that, whereas an individual's personality is partly constituted by the property that he or she owns, so that property can be seen as essential to the ways in which individuals constitute and define themselves, no such claim can be made with respect to mere abstract holdings of wealth. Although wealth permits the acquisition of property and participation in activities and experiences which might help to constitute and define the self in the future, the very fact that wealth has not been transposed into these things precludes it from being considered as important as actual holdings of property. The protection of property interests ought, therefore, to precede the protection of mere economic interests.

Drying Up

The building of the Hongyashan Reservoir leads to the natural watercourse drying up in the downstream of Shiyang River Basin and the Rump lake disappearing. Lining Channels was used to conveying water to Qingtu Lake since the Key Management has been carried out in Shiyang River Basin.In spite of small regional environment improved, the river and the lake can not be connected with each other as the natural watercourse remain discarded.As a result the ecological restoration of Qingtu River can not work effectively.Starting from restoring the ecological function of rivers and lakes, the pattern of conveying water should be changed into supplementing water to Qingtu Lake with the natural watercourse of Shiyang River,connecting the lake and the river.Meanwhile the jointed scheduling mode of surface water and groundwater ensures the dynamic balance of ground water and the sustainable development of oasis.
