基于近年来芬兰VT技术研究中心在混凝土性能和耐久性方面的研究成果,对多重劣化机制共同作用下混凝土耐久性能表现进行了综述。这些研究是建立在30余年来有关混凝土耐久性的研究结果之上,包括15年的现场暴露实验数据,有关混凝土耐久性能是通过实验室加速实验结果和现场暴露实验结果共同评价的。结果显示,实验室的单一因素作用下的混凝土耐久性加速劣化结果与多因素共同作用下的暴露实验和工程现场测试结果有很大的差异。现场测试能够获得较长期的混凝土耐久性结果,这可以用来校准和验证混凝土耐久性和寿命预测模型,并引导继续对多因素共同作用下混凝土的耐久性能进行更全面深入的研究。

捕食是小哺乳动物死亡最常见的原因,也导致被捕食动物遗骸发生明显改变。动物死亡后的风化、踩踏、搬运等过程也会改变动物的骨骼并影响到化石组合的形成。本文研究了内蒙古大庙三个中新世化石地点,时代从早中新世到晚中新世早期(约21~11.6 Ma)。通过分析各小哺乳动物化石组合的沉积背景以及埋藏学特征识别化石埋藏的主要成因。结果显示出捕食是三个地点小哺乳动物化石埋藏的基本成因,而在两个年轻的地点中也有流水搬运与可能的踩踏因素的叠加。三个地点可能存在不一样的捕食者:早中新世地点以猫头鹰捕食为主,中、晚中新世地点则以日间活动的鸟类或哺乳类为主要捕食者。研究还显示小哺乳动物的系统发掘是可行的,在一定程度上可以减少采样过程中产生的破坏。

Chest wall reconstruction after rib resection is essential to ensuring chest wall stability, avoiding flail chest and pulmonary hernia, and improving pulmonary function. Traditionally, a synthetic mesh and a musculocutaneous flap have been used to bridge the chest wall defect. However, a risk of secondary prosthesis infection exists. Acellular dermal collagen mesh implants (Permacol™) are indicated for the reconstruction and reformation of human soft connective tissue. A case of a complex chest wall reconstruction after rib resection for osteomyelitis due to staphylococcus aureus infection in a malnourished, immunosuppressed, and methadone-addicted patient is presented. The patient underwent a left posterolateral thoracotomy and chest wall resection, involving three ribs and the soft tissues overlying an infected cutaneous fistula. The chest wall was reconstructed using a 28 × 18 cm piece of porcine sterile acellular dermal collagen mesh. A successful chest wall repair was achieved with no incisional herniation and with complete mesh incorporation, allowing physiologic respiratory movements. A typical wound seroma developed and resorbed over the following months. There was no infection. In conclusion, this case report suggests that Permacol™surgical implant can be used successfully as an alternative to synthetic mesh in reconstruction of an infected chest wall.
