This research aims to give rights to the prospective husband and wife who are going to get married to protect their property before getting married. The pre-marriage agreement actually aims to protect each individual as a legal subject whose rights are protected. The Prenuptial Agreement is an interesting...

A case-Based Method is a flexible form of learning that includes problem-based learning and encourages reasoning skills development. It enables students’ high-order thinking skills to follow Bloom’s taxonomy of cognitive learning by exposing knowledge in the form of narration with questions and activities...

Objectives: Erectile dysfunction (ED) represents an early marker of vascular damage and a potent factor for future cardiovascular events. Our study aims to investigate interrelationships between ED, arterial stiffness and left ventricular geometry. Methods: We analyzed data from 85 ED patients (mean...

Background: Timing errors during Intra-Aortic Balloon Pump (IABP) support can be detrimental when interfering with cardiac function. In vivo hemodynamics and left ventricular (LV) function were monitored during premature IAB inflation, and the associated mechanisms investigated with Wave Intensity Analysis. Methods:...

To what degree elevated pulsatile components of blood pressure arise from a primary interaction of ventricular contraction with the impedance of the arterial tree or from more complex phenomena involving backward wave travel in the arterial tree is unknown. We used wave intensity analysis to explore...

Compared with other countries, especially China, United States, United Kingdom, Japan and Germany, Australia’s online retail fall behind in terms of both its sale and percentage contribution to the total retail. This paper analyses David Jones, which is typical of large department store chains, and Australian...

We present an extension of a family of second-order integrable mappings to the case where the variables do not commute. In every case we introduce a commutation rule which is consistent with the mapping evolution. Through the proper ordering of variables we ensure the existence of an invariant in the...

This paper shows that several integrable lattices can be transformed into coupled biliear differential-difference equations by introducing auxiliary variables. By testing the Bäcklund transformations for this type of coupled bilinear equations, a new integrable lattice is found. By using the Bäcklund...

Electromagnetic wave propagation through cold collision free plasma is studied using the nonlinear perturbation method. It is found that the equations can be reduced to the modified Kortweg-de Vries equation.
