buckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Seasonal variation in development of in vitro produced bovine embryos.
The neurological examinations and intra-aortic perfusion were performed with the assistance of Dr T. J. Anderson, Department of Veterinary Clinical Studies, University of Glasgow Veterinary School. Professor I. R. Griffiths provided valuable advice on the interpretation of pathological findings. Mr R. Irvine and Mr J. Ramsey performed dissections on the cadavers. The processing ofthe epoxy resi...
متن کاملAlgorithms for automatic segmentation of bovine embryos produced in vitro
In vitro production has been employed in bovine embryos and quantification of lipids is fundamental to understand the metabolism of these embryos. This paper presents a unsupervised segmentation method for histological images of bovine embryos. In this method, the anisotropic filter was used in the differents RGB components. After pre-processing step, the thresholding technique based on maximum...
متن کاملIntrinsic factors affecting apoptosis in bovine in vitro produced embryos.
The main purpose for human assisted reproductive technologies (ART) is clearly to bypass reproductive failures. This purpose is totally different from the aims in animal ART, being genetic improvement and more recently conservation of endangered species. Apoptosis or programmed cell death has been detected before implantation in in vivo as well as in vitro embryos and might contribute to lower ...
متن کاملTransition of cell numbers in bovine preimplantation embryos: in vivo collected and in vitro produced embryos.
The total cell numbers (TCNs) of bovine embryos collected from superovulated donors (VIVO embryos) were counted 0-9 d after ovulation to quantify the developmental process. Using numerical analysis of embryo development, we also compared the developmental process of VIVO embryos, in vitro-fertilized (IVF) embryos and nuclear transfer (NT) embryos obtained from enucleated oocytes and blastomere ...
