Numerical Study on Depinning Dynamics of Fluids Interacting with Disorder

引用

Communications in Theoretical Physics 2004年第4X期42卷 619-622页

作者： CAOYi-Gang W.k.Chow DepartmentofBuildingServicesEngineering TheHongKongPolytechnicUniversityHongKongChina

We investigate the depinning of two-dimensional fluids interacting with quenched disorder, based on Langevin simulations. For weak.disorder the fluids depin elastically and flow in an ordered state. A power-law scaling lit between velocity and driving force can be obtained for the onset of motion in the elastic regime. This is in good agreement with that of colloid, charge density wave, and superconducting vortex systems. With an increasing strength of the disorder, we find a sharp crossover to plastic de. Pinning, accompanied by a substantial increase in the depinning force. The scaling fit obtained in the elastic regime becomes invalid when plastic flow occurs. In the plastic regime, the fluids flow in channels and the hexatic order decays exponentially with drives.

Epithelial-Myoepithelial Carcinoma of Parotid Gland—A Surprising Clinical Entity

引用

Surgical Science 2012年第5期3卷 274-278页

作者： Jaimanti Bak.hi Grace Budhiraja k.ran Gupta Sourabha k. Patro Nalini Gupta Department of Otolaryngology & Head-Neck.Surgery & Department of Cytopathology PGIMER Chandigarh India

Objective: Objective of this study is to highlight the importance of considering clinical and radiological findings in parotid tumors before operating tumors with high suspicion of malignancy though reported as benign on histopathology. Material and Methods: 20 years old female patient underwent radical parotidectomy for epithelial-myoepithelial carcinoma of the left parotid gland which was diagnosed on FNAC. Contrast CT and contrast MRI also showed a tumor involving left parotid gland with destruction of ramus of mandible and loss of tissue planes medially & laterally. Facial nerve was infiltrated by tumor, thus sacrificed. Post operatively, patient had left facial palsy and was discharged after 7 days without any other sequelae. Postoperative histopathology showed pleomorphic adenoma with positive resection margins medially, superiorly & posteriorly. No further treatment was given in view of the benign nature of the tumor. Results: Patient was k.pt on monthly follow up and was disease free at one year follow up. Conclusion: Aggressive surgical treatment should be planned for malignant parotid tumors to give a better tumor free survival. Misdiagnosis can occur on FNAC as it can hit only one part of the tumor thus missing a malignant tumor or can interpret pleomorphic adenoma as epithelial-myoepithelial carcinoma.

Effect of Seed Sizes on the Growth and Establishment of Seedlings of Sheanut Tree （Vitellaria paradoxa）

引用

Journal of Agricultural Science and Technology 2011年第4期5卷 428-432页

作者： G.O. k.lawole k. A. Adebayo M. A. Adebayo Department of Agronomy Ladoke Akintola University of Technology Ogbomoso 210001 Oyo State Nigeria

Seed size can influence germination, emergence and further development of plants to produce high yield. Therefore, pot trial was conducted to assess the effects of seed sizes on growth and establishment of sheanut tree seedlings （Vitellaria paradoxa） in tlae southern Guinea savanna of Nigeria. Seedlings produced from large sized seed had higher germination （80%） than those from medium （70%） and small （65%） sized seeds. Number of days to emergence of seedling from large-sized seed planting was 30 days, 49 days for small- and medium-sized seeds. Large sized seeds had higher N, P, k. Ca and Mg contents compared with small and medium sized seeds. Generally, seedlings from large sized seeds had about 1.5 times more leaves than medium sized seeds and about 2 times more leaves than small sized seeds at 8, 10, 12, 14 and 16 week. after planting （WAP）. Seedlings from large sized seeds were taller and had larger stem girth （at 16WAP） than those from medium sized seeds. Variations in seedling growth from seed sizes could be of operational importance in nursery management as seeds can be sown according to size to improve uniformity. However, further studies to ascertain if the superior growth of seedlings from large sized seeds will lead to higher yield is recommended.

Micro-structural and Dielectric Properties of Porous TiO2 Films Synthesized on Titanium Alloys by Micro-arc Discharge Oxidization

Southwestern Institute of Physics Annual Report

Southwestern Institute of Physics Annual Report 2006年第1期 207-208页

作者： JIN Fanya TONG Honghui SHEN Liru WANG k. Chu Paul k.

Titanium oxides （TiO2） and TiO2 films have recently attracted more attention on the application of microelectronic devices and microwave communication systems for processing temperature and environmentally stable dielectric properties characterized by high relative dielectric constant and low dielectric loss. Many deposition methods have been used to prepare TiO2 films including pulsed laser deposition, filered arc deposition, sol-gel method and reactive sputtering methods. Previous reports on TiO2 films prepared by MDO have primarily focused on surface mechanical and biologic properties, in contrast.

Another piece of the meiosis puzzle

Asian Journal of Andrology 2017年第1期19卷 3-4页

Meiosis, the process by which the ovary and testis produce haploid gametes from initially diploid cells, is essential for sexual reproduction in mammals. This process, initially described in the late 19th and early 20th century using model organisms such as sea urchins, worms and fruit flies, continues to attract extensive interest from reproductive biologists due to its centrality in gametogenesis.

本研究探讨了单一性伙伴(n = 222)、两个以上性伙伴(n = 145)与无性伙伴(n = 106)三组低收入女性的长期配偶偏好、人生阅历、生活史特质与个人特征的关系。研究结果显示三组女性的配偶偏好趋于一致,繁衍策略的组别差异与人生阅历和所处环境具有较高相关,三组女性并不偏好特定类型的配偶。路径分析显示首次生育年龄直接预测配偶数量,受教育水平和初次性交时间对配偶数量与首次生育年龄之间的关系具有显著调节作用;女儿与父亲相处的时间可以预测初次性交年龄。研究结果显示父亲投资影响青少年性行为发展的时间表,人类繁衍的长期进化是性行为变化的根源。
