background and objectives: thermal processing is an effective method in preventing microbial spoilage but high heat transfer in a long time process that leads to quality loss and increased energy consumption. also it is important to consider sensitive nature of food products during the thermal processing. due to the nano-fluids' unique thermo–physical properties compared with the conventio...
Mobile robots that consist of a mobile platform with one or many manipulators mounted on it are of great interest in a number of applications. Combination of platform and manipulator causes robot operates in extended work space. The analysis of these systems includes kinematics redundancy that makes more complicated problem. However, it gives more feasibility to robotic systems because of the e...
Background. This study aims to analyze the movement of backhand and forehand smash stroke techniques in badminton in three dimensions using a kinematics approach. Objectives. The obtained results were analyzed using a descriptive and quantitative approach. Methods. Furthermore, 24 male badminton players from the university student activity unit with an average age of 19.4 ± 1.6 years, height ...
A detailed review of the asymptotic matching procedures predicting formation number vortex rings is presented. The original studies Mohseni and Gharib [“A model for universal timescale ring formation,” Phys. Fluids 10(10), 2436–2438 (1998).], Shusser new inviscid rings,” in 30th AIAA Fluid Dynamical Conference (1999).], Linden Turner [“The ‘optimal’ rings, efficiency propulsion devices,” J. Mec...
Objective: Attention can be paid to the biomechanical characteristics of running since the speed of running varies. The aim of the present study was to investigate the effects of increasing running speed on the three-dimensional kinematics of the lower limb’ joints in the stance phase. Methods: The research was quasi-experimental. 27 volunteer subjects ran on a treadmill and the kinematic and ...

We investigate the transient viscoelastic response of weakly strain-hardening fluids to imposed elongational deformation in filament stretching devices. We combine timedependent finite-element simulations with quantitative experimental measurements on a rheologically well-characterized test fluid to investigate how well the device reproduces the ideal transient uniaxial extensional viscosity pr...
Objective Stroke occurs when the supply of blood to the brain is either interrupted or reduced. The clinical presentation varies from minor neurological symptoms to severe deficits, depending on the location and the size of the brain lesion. Hemiparesis is one of the most striking features in the acute phase. Many other deficits may also be present, including postural imbalance. All persistent ...
Aim and Background: hypothermia is a common complication in surgeries patients and may have serious consequences in both mother and fetal in cesarean surgery. This study was implemented to assess the effect of intravenous (IV) infusion of warm fluids on decreasing hypothermia in mothers and its consequences on ne...
The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....
