with the aim of a determination of physical properties of date palm male flowers, as well as optimum flower detachment conditions, this study was carried out in two parts. in the first part of the study, the palm groves of khuzestan province were totally surveyed. “ghanami” cultivar was in the end selected to be studied as the superior cultivar in the region. drying up of the male flowers at 70...

In this study, numerical analysis of a composite spring with nonlinear elastic force-displacement relationship was performed. Due to the lightness and durability materials, their use in automotive industry is increasing production methods allow for high performance design. The behavior pair leaf springs working tandem cross-section profiles be obtained by using involute curve spur gear pairs un...

To achieve various manipulation tasks by robot fingers, we have to use both position control and force control appropriately. In this paper, we propose a method to determine such control modes of robot fingers in graspless manipulation. Using the method, we can assign a positionor force-control mode to each robot finger so that the maximum manipulation stability will be achieved without excessi...

The main objective of the investigation was the determination of whether prestretching would decrease the rapid force loss of the elastic polymers. The results indicated that Alastik CK chains showed a significant decrease in force loss whereas the C2 chains were unaffected. Since overextending the chain to compensate for force loss during clinical placement could result in capillary bed ischem...

The Hamiltonian equation of motion is studied for a vortex occuring in 2dimesional Heisenberg ferromagnet of anisotropic type by starting with the effective action for the spin field formulated by the Bloch (or spin) coherent state. The resultant equation shows the existence of a geometric force that is analogous to the so-called Magnus force in superfluid. This specific force plays a significa...

BACKGROUND Anesthetics act in the spinal cord to suppress movement evoked by a noxious stimulus, although the exact site is unknown. METHODS This study investigated sensorimotor processing in hind limb withdrawal reflexes, and effects of two general anesthetics, halothane and isoflurane, on simultaneously recorded responses of single dorsal horn neurons and hind limb withdrawal force, elicite...

[Purpose] The aim of this study was to clarify the relationships among muscle fiber conduction velocity, time-force characteristics of muscle force production, and voluntary movement in patients with hemiplegia. [Subjects and Methods] The participants in the present study were 13 patients with hemiplegia. Muscle fiber conduction velocity, deep temperature of muscles and muscle thickness were me...

Significant progress has been made in recent years on development of molecularly based methods for accurate prediction of chemical and physical properties relevant for product and process design. A number of ideal-gas properties are routinely predictable. However, despite progress in computing hardware and simulation methodologies, prediction of condensed-phase properties of interest to industr...
