In the injection molding process, plastic products are difficult to demold due to friction force between the cavity and products, thus, finished products might be deformed or damaged. Therefore, designers should add a draft angle to the geometric surface of products, which is parallel to the unloading direction, in order to help the products eject smoothly from the cavity. This study uses CAD s...

the normal carrying angle in shiraz population was measured on the basis of sex and age. the right elbow angle of 4266 cases was examined from birth to 30 years old. this study found the carrying angle in 2540 females to be 7.20 (range 2-19) and in 1726 males to be 6.40 (range 2-11), a 0.80 difference. a significant difference (p= 0.05) was found in relation to age. there is a gradual increase ...

The present study aims to numerically simulate the thrust vectoring by secondary injection. analysis of flow for this was done using ANSYS Fluent. kω-sst turbulence model used. baseline solver selected as a double-precision Density-based coupled solve with implicit time integration. Least squares cell-based spatial discretization in which solution assumed vary linearly used and second-order upw...

We have modeled the injection and acceleration of pickup ions at the solar wind termination shock and investigated the parameters needed to produce the observed Anomalous Cosmic Ray (ACR) fluxes. A non-linear Monte Carlo technique was employed which in effect solves the Boltzmann equation and is not restricted to near isotropic particle distribution functions. This technique models the injectio...

objective(s):glaucoma is the second leading cause of blindness and it is related to oxidative stress based on numerous studies. glutathione s-transferases (gsts) are members of multigenic family, which have important role in cells as an antioxidant. in the present study, we examined the polymorphism of gstt1 and gstm1 deletion genotypes (t0m1, t1m0, and t0m0) in 100 glaucoma patients (41with pr...

Experiments were carried out to evaluate the performance of a medium grade LHR diesel engine consisting of air gap insulated piston with 3-mm air gap, with superni (an alloy of nickel) crown and air gap insulated liner with superni insert with different operating conditions of jatropha oil in crude from and biodiesel form with varied injection timing and injection pressure. Performance paramete...

AIM To determine the 2-year outcomes of intravitreal bevacizumab (IVB) injections in eyes with macular oedema (ME) following branch retinal vein occlusion (BRVO). METHODS Of 105 consecutive eyes (105 treatment-naïve patients) with ME following BRVO, 89 eyes were followed for 2 years after the first injection. During the 2-year follow-up period, patients were examined at least every 3 months a...

PURPOSE To compare the short-term effects of intravitreal triamcinolone acetonide (IVTA) with those of intravitreal bevacizumab (IVB) injection for diabetic macular edema (DME). METHODS The present retrospective, comparative case study included 58 eyes of 35 consecutive patients (IVTA group, 20 eyes; IVB group, 38 eyes) with DME. IVTA (4 mg) or IVB (1.25 mg) injection was performed under loca...

The objective of this research was to develop advanced diesel combustion strategies for emissions reduction in a multi-cylinder diesel engine. The engine was equipped with an electronically-controlled, common-rail fuel injection system, and an exhaust gas recirculation (EGR) system. This experimental setup allowed a wide range of operating conditions to be explored. Effects of various injector ...

Intravitreous injection is a widely used technique in visual sciences research. It can be used to establish animal models with ocular diseases or as direct application of local treatment. This video introduces how to use simple and inexpensive tools to finish the intravitreous injection procedure. Use of a 1 ml syringe, instead of a Hamilton syringe, is used. Practical tips for how to make appr...
