The purpose of this paper is to apply the exp‐function method to construct exact solutions of nonlinear wave equations. The proposed technique is tested on the (2+1) and (3+1) dimensional extended shallow water wave equations. These equations play a very important role in mathematical physics and engineering sciences.

In this paper, the authors apply the exp‐function method to construct exact solutions of nonlinear wave equations.

In total, four forms of the extended shallow water wave equation have been studied, from the point of view of its exact solutions using computational method. Exp‐function method was employed to achieve the goal set for this work. The applied method will be used in further works to establish more entirely new solutions for other kinds of nonlinear wave equations. Finally, it is worthwhile to mention that the proposed method is straightforward, concise, and it is a promising and powerful new method for other nonlinear wave equations in mathematical physics.

The algorithm suggested in the paper is quite efficient and is practically well suited for use in these problems. The method is straightforward and concise, and its applications are promising.

The aim of this study was to assess the effect of hydration with oral water on non-stress test (NST).

The study was conducted as single-blinded and randomized controlled. Healthy and outpatient 32- to 40-week pregnant women who were aged 19 and older were included in the study. Intervention group pregnant women (n = 66) drank 500 ccs of water before the NST, and no attempt was made to the control group (n = 66). The NST parameters of the groups with fetal heart rate (FHR), variability, acceleration, deceleration, reactivity and nonreactivity were evaluated.

Both groups were found to be similar in terms of their descriptive characteristics and variables related to pregnancy (p > 0.05). The median FHR was 130.0 in the intervention group, 140.0 in the control group (p < 0.001), and the median number of the acceleration was 6.0 in the intervention group and 4.0 in the control group (p < 0.001). In terms of the median number of decelerations, the groups were similar (p > 0.05).

It was found that hydration with oral water had an effect on NST parameters of FHR and the number of accelerations. However, it was observed that the FHR was within the normal range in both groups. It was thought that it tended to increase the number of accelerations.
