Humble Opinion of Roof Gardens

1 GENERALRoof gardens can be extensively interpreted as ageneral designation, which means building variousrecreational garden on roofs, gazebos and terracesof both ancient and modern buildings, structures, andbridges (flyovers) (Jin Weiping, 1996). Cities aredensely populated and land is costly, so shortage ofland is one of the restrictive factors in green urbandevelopment. According to statistics, the green spaceis 2~3 m2 per capita in Chinese cities. As a result, todevelop roof gardens h…     

Effects of phenylbutazone and indomethacin on the post-operative course following experimental orthopaedic surgery in dogs

Randomized placebo-controlled crossover studies were carried out in dogs to evaluate how two non-steroidal anti-inflammatory drugs (NSAID) might modulate an acute post-traumatic inflammatory reaction. Two "identical" surgical interventions were performed on the forelimbs of each animal with an interval of 28 days, to enable a paired comparison of the inflammatory signs and the wound/bone healing processes. At one operation 8 dogs received 300 mg phenylbutazone twice daily for 8 days starting on the day before surgery, and at the other operation matching placebo tablets were given. In a similar placebo-controlled trial another group of 8 dogs received 5 mg indomethacin twice daily. With phenylbutazone the post-operative swelling was not significantly reduced compared to placebo, but there was less pain and limping. With indomethacin the swelling was somewhat reduced, but there was no consistent difference to placebo in the pain and limping assessments. None of the drugs appeared to distinctly effect the wound or fracture healing, as evaluated by clinical inspection, comparison of radiographs and comparison of bone sections from the sites of surgery. It proved difficult to select an appropriate dosage of indomethacin due to its high potential to induce GI ulceration and bleeding in dogs. In this experimental surgical model with an acute inflammation, neither phenylbutazone nor indomethacin showed impressive anti-inflammatory or analgesic properties. In the same model paracetamol has proved to significantly and more efficiently, reduce both swelling and pain without any noticeable adverse effects, and appears to be a better alternative than the two presently tested NSAID.     

四川新津白鹤滩国家湿地公园核心区植物景观配置研究

四川新津白鹤滩国家湿地公园位于成都市新津县境内,是典型的河流漫滩和沙洲地貌。受亚热带湿润气候影响,湿地公园核心区拥有种类丰富的湿地动植物资源,但近几年人们在场地周边的开发活动,对基地原有植物生态环境造成破坏_^[1]。现在核心区仅存那些对水质要求低和抗逆性强的植物,同时也因为植物种类过于单一,随之而来的就是湿地季节性功能失调现象,如对水质净化的能力差,水体富营养化严重。为缓解和改善湿地核心区现存问题,一个具有生态修复功能的植物景观配置就显得尤为重要,本论文主要以生态恢复学、植被演替理论等为理论支撑,借鉴LID技术在湿地生态修复的应用,结合对基地本身植物资源调查的基础,通过对不同植物的配置选择,构建起了多样的新旧植物景观模式,用以探索科学合理的湿地公园植物景观配置模式,以期恢复新津湿地公园植被生态多样性,提升视觉景观效果。
