Although initially originated as a totally empirical relationship to explain the volume of trade between two partners, gravity equation has been the focus of several theoretic models that try to explain it. Specialization models are of great importance in providing a solid theoretic ground for gravity equation in bilateral trade. Some research papers try to improve specialization models by addi...

Introduction: The aim of this study was to eva-luate the salivation flow rate objectively using Schirmer test and mouth dryness and other con‌sequences subjectively by distributing question‌naires to patients receiving head and neck radio‌therapy. Materials and Methods: In this descriptive study that was carried out at Imam Khomeini hospital, Tehran, Iran, the saliva flow rate of 33 patients r...

Transport connectivity is a crucial determinant of bilateral exports. This paper presents an empirical assessment of the relationship between bilateral maritime liner shipping connectivity and exports in containerizable goods during the period 2006–2013. Making use of probed “gravity” type trade models, the paper incorporates new data on different measurements of maritime distance, as well as a...

The purpose of this study was to investigate bilateral deficit patterns during maximal hand-grip force production in late postmenopausal women. Twenty and 20 young premenopausal women performed isometric grip tasks with dominant nondominant hands both hands, respectively. For women, pulse wave analysis used for identifying a potential relationship between strength risk factors cardiovascular di...

BACKGROUND To evaluate the relationship of the intercondylar notch width with unilateral and bilateral ACL injury by using MR images. MATERIAL AND METHODS The intercondylar notch width index was measured on the MR images of 18 patients with a bilateral ACL injury, 38 patients with a unilateral ACL injury and 53 healthy subjects with a normal ACL and the results of all groups were compared wit...

A 68-year-old man developed bilateral sequential non-arteritic anterior ischaemic optic neuropathy, each episode occurring with a close temporal relationship to influenza vaccination.

Spontaneous fluctuations in the blood oxygenation level-dependent (BOLD) MRI signal during the resting state are increasingly being studied in healthy and diseased brain in humans and animal models. Yet, the relationship between functional brain status and the characteristics of spontaneous BOLD fluctuations remains poorly understood. In order to obtain more insights into this relationship and,...

Previous behavioral research points to a positive relationship between maternal touch and early social development. Here, we explored the brain correlates of this relationship. The frequency of maternal touch was recorded for 43 five-year-old children during a 10 min standardized play session. Additionally, all children completed a resting-state functional magnetic resonance imaging session. In...

This paper analyzes the structure and functions of suppliers’ associations (kyoryokukai) in the automobile industry in Japan. The bilateral assembler-supplier relationship has received much attention recently as a source of Japanese industrial competitiveness. However, this paper argues that the hitherto neglected area of inter-supplier coordination in technology diffusion is at least as import...
