impulse buying behavior is one of main concepts in marketing. it is affected on various factors such as cultural factors, psychological factors, personal factors and positional factors. buying can be done because of different reasons (including of needing a production) and this fact aids marketers to better understand consumers’ behavior. impulse buying is one of pervasive aspect of consumer be...

zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. the efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of na+ and make depolarization na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. also it is an effective blocker of one subtype of tetrodoxine (...

BACKGROUND Treadmill animal models are commonly used to study effects of exercise on bone. Since mechanical loading induces bone strain, resulting in bone formation, exercise that induces higher strains is likely to cause more bone formation. Our aim was to investigate the effect of slope and additional load on limb bone strain. METHODS Horizontal and vertical ground reaction forces on left f...

In this report, the author first describes the design of a portable model foundation loading device capable of applying square wave impulses with forces up to 1200 lbs. for durations between 10 and 120 milliseconds. The model loading device is used to simulate the load on the non-recoiling parts of a howitter foundation in both sands and clays. An important part of this program is the compariso...

PURPOSE To identify the effect of additional elastic force on the kinetic and kinematic characteristics, as well as the magnitude of leg stiffness, during the performance of accentuated countermovement jumps (CMJs). METHODS Fifteen trained male subjects performed 3 types of CMJ including free CMJ (FCMJ; ie, body weight), ACMJ-20, and ACMJ-30 (ie, accentuated eccentric CMJ with downward tensil...

Building facades in commercial and residential buildings in Australia, UK and elsewhere are highly vulnerable to terrorist threats involving explosive blast loading. The modelling of consequences to built infrastructure when subject to blast loading is well developed; however, considerable uncertainty remains with respect to system response and explosive loading parameters. In this paper, struc...

Asymmetries in sagittal plane knee kinetics have been identified as a risk factor for anterior cruciate ligament (ACL) re-injury. Clinical tools are needed to identify the asymmetries. This study examined the relationships between knee kinetic asymmetries and ground reaction force (GRF) asymmetries during athletic tasks in adolescent patients following ACL reconstruction (ACL-R). Kinematic and ...

Research at the Explosion Dynamics Laboratories at Caltech over the past three years under an ONR contract has examined many issues critical to Pulse Detonation Engine (PDE) development. These include: fundamental and applied studies of detonation initiation; detonation cell width measurements to characterize fuels, including JP10; visualization of the reaction zone structure of propagating det...

OBJECTIVE To determine if five days of practice on a novel dynamic, multi-joint pulling task resulted in lower magnitudes of lumbar loading or a more consistent relationship between pulling force and lumbar loading. DESIGN A repeated measures design compared how practice influenced the magnitude of lumbar torque and the correlations between lumbar torque and pulling force. BACKGROUND Previo...
