Drop impingement of water and aqueous SDS solution on polycarbonates

The impact dynamics of pure water and an SDS solution at a concentration of 2.5 cmc (g = 38.9 mN/m)impinging on polycarbonate surfaces were studied. The relaxations of wetting diameter, drop height andcontact angle were examined under four impact velocities (0.451.1 m/s) with three different roughness(15114 nm). The effects of surface tension, impact velocity and surface roughness were investigated. Two new phenomena have been observed: all water drops, independent of their impact velocity, recededback to the same wetting diameter on smooth surfaces, and water drops at a low impact velocity showednearly the same wetting behavior on polycarbonates with different roughness.

Objective: The malignant transformation (MT) of ovarian mature cystic teratoma (MCT)to squamous cell carcinoma (SCC) is very rare. This study analyzed cases from multiplemedical centers in Taiwan to investigate the clinicopathologic characteristics, treatment, andprognostic factors of this disease and reviewed related literature. Methods: Pathological reports of 16,001 patients with primary ovarian cancer who weretreated at Taiwan medical centers from 1990 to 2011 were reviewed. In total, 52 patients withMT of MCT to SCC were identified. Results: Among all ovarian MCTs, the incidence of MT to SCC is 0.2%. The median age ofpatients was 52 years (range, 29–89 years), and the mean tumor size was 10.5 cm (range, 1–40cm). We analyzed the patients in our study and those in the literature and determined thatearly identification and complete surgical resection of the tumor are essential for long-termsurvival. In addition, adjuvant chemotherapy or concurrent chemoradiotherapy can be usedto treat this malignancy. Old age, large tumor size (≥15.0 cm), and solid components in MCTsare suitable indicators predicting the risk of MT of MCT to SCC. Conclusion: Similar to general epithelial ovarian cancers, the early detection of MT of MCTto SCC is critical to long-term survival. Therefore, older patients with a large tumor or those with a tumor containing a solid component in a clinically diagnosed MCT should beevaluated to exclude potential MT to SCC.
