Nonlinear dynamic analysis of a four-bar mechanism having revolute joint with clearance
In general, joints are assumed without clearance in the dynamic analysis of multi-body echanical systems. When joint clearance is considered, the mechanism obtains two uncontrollable degrees of freedom and hence the dynamic response considerably changes. The joints’ clearances are the main sources of vibrations and noise due to the impact of the coupling parts in the joints. Therefore, the syst...
متن کاملReovirus oncolysis: a brief insight on molecular mechanism and immunological aspect
Abstract : Reovirus (respiratory enteric orphan virus), a naturally occurring benign human pathogen, has an inherent ability to target transformed and cancerous cells and cause their lysis, while leaving non-transformed cells relatively unaffected. The efficiency of this innate oncolytic activity of reovirus correlates with expression of the ras oncogene. Cells expressing ac...

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Synthesis of Multifunctional Nanogels Using a Protected Macromonomer Approach.
Nanoparticles possessing multiple functionalities provide synthetic handles for varied surface chemistries, making them useful for a range of applications such as biotargeting and drug delivery. However, the combination of interfering functionalities on the same particle is often challenging. We have employed a synthetic scheme involving chemical protection/deprotection to combine interfering f...
متن کاملPolyamine-polyamine oxidase interaction: part of maternal protective mechanism against fetal rejection.
Human retroplacental blood serum significantly (p less than 0.01) suppresses the in-vitro uptake of 3H-thymidine--that is, synthesis of deoxyribonucleic acid--by spontaneously growing human lymphocytes in the presence of exogenous spermine, but only in concentrations with a higher polyamine oxidase activity than that found in maternal peripheral blood serum during pregnancy. These findings toge...
