Abstract
Purpose
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.
Design/methodology/approach
In this paper, the authors apply the exp‐function method to construct exact solutions of nonlinear wave equations.
Findings
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.
Originality/value
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.

Abstract
Purpose
This study aims to discover whether COVID-19 phobia has a positive and significant effect on the stress, depression and anxiety levels of industrial consumers in addition to reveal whether environmental awareness plays a mediating role between COVID-19 phobia and stress, depression and anxiety.
Design/methodology/approach
In this study, a quantitative method was used to reveal the role of anxiety, depression and stress (psychological effects) and environmental awareness caused by covid-19 phobia on industrial consumers. The universe of the study is small and medium-sized enterprises operating in the province of Sanliurfa, which is located in the southeast region of Turkey and the second largest city in the region, and are industrial customers. Questionnaire method was used in the study. In addition, data were collected from 406 people who agreed to participate in the study. In the study, in which intermediary and regulatory analyzes were made, the process macro program was used.
Findings
The results show that there is a medium relationship between COVID-19 phobia and environmental awareness; and COVID-19 phobia and stress, depression and anxiety. No relationship was found between environmental awareness and stress, depression and anxiety. COVID-19 phobia was found to have a positive and significant effect on environmental awareness and stress, depression and anxiety, while environmental awareness was found to have no effect on stress, depression and anxiety. Finally, environmental awareness was found to play a mediating role between COVID-19 phobia and stress, depression and anxiety.
Research limitations/implications
In this study, four hypotheses were developed. Of these hypotheses, three are for the simple effect and one for the mediation effect. Out of four hypotheses, three were supported. The most important inference obtained from the study was finding the mediation effect of environmental awareness between COVID-19 phobia and anxiety, depression and stress.
Originality/value
To the best of the authors’ knowledge, no studies in the literature were made on the relationship among COVID-19 phobia, environmental awareness, stress, depression and anxiety. This study also examines the mediating effect of environmental awareness in the relationship between COVID-19 phobia and stress, depression and anxiety. The fact that the study is on the negative effects of the pandemic on one of the most affected occupational group also increases its original value.

Abstract
Development of Self Compacting Concrete (SCC) is considered as one of the most significant development in the construction industry due to its numerous inherited benefits. With the introduction of super-plasticizers and viscosity modifying agents, it is now possible to produce concrete with high fluidity, good cohesiveness which does not require external energy for compaction. The proper understanding of the effects of elevated temperatures on the properties of SCC is necessary to ensure the safety of buildings made with SCC during fire. During the present investigation, an attempt has been made to study the stress-strain behaviour of Normal Compacting Concrete (NCC) and Self Compacting Concrete at a temperature of 900°C. A significant reduction in the Ultimate compressive strength of SCC was observed during this study. The reduction was found to be more for SCC compared to Normal compacting concrete. The reduction in the compressive strength of SCC was found to be 81.5 % for M40 concrete when exposed to 900°C.

Abstract
Purpose
The purpose of this paper is to show how an application of fractional two dimensional differential transformation method (DTM) obtained approximate analytical solution of time‐fraction modified equal width wave (MEW) equation.
Design/methodology/approach
The fractional derivative is described in the Caputo sense.
Findings
It is indicated that the solutions obtained by the two dimensional DTM are reliable and that this is an effective method for strongly nonlinear partial equations.
Originality/value
The paper shows that exact solutions can also be obtained from the known forms of the series solutions.

Abstract
Purpose
The trust in participation banks depends largely on authentic dependence on Sharia, legal financial instruments and fair yet transparent distribution among account owners and banks. Taking into account the economic Islamic principles and those of mudarabah agreement, this study aims to identify problematic areas pertaining to profit sharing in addition to revealing opportunities leading to the improvement of the profit distribution system while developing a new profit distribution system proposal.
Design/methodology/approach
This study proposes two hypotheses (H). H1: There are partial deviations between the profit considered to be legal according to the economic principles of Islam and the practice of participation banking. H2: There are partial deviations or loss of right in practice between the mudarabah contract concluded among owners of participation account and participation banks. In-depth interview technique and review of the literature including legislation were used to determine the parameters affecting the distributed profit. The collected data was tested through comparison with the theoretical framework of the mudarabah contract.
Findings
There are two separate fund pools used in participation banks, including equity and participation accounts. Managers’ selection of pools set according to their personal goals related to balance sheet profit management may cause profit to pass between participation accounts and equity. Many issues negatively affect the distributed profits. For example, incomes from funding commissions, reserve requirements and idle funds, although they originate from participation accounts, are recorded in the bank’s income. In addition, the bank does not return the profit initially recorded in its own account to participation pools, whether or not profit.
Research limitations/implications
The interviewed officials were cautious to avoid a negative perception of the sector. This made it difficult to determine the real situation of applications decided with initiative in profit distribution. Although the authorization documents have partially been published, it is still difficult to access most licensed documents. There is no independent audit report made considering the interest-free banking principles regarding the profit distribution system of participation banking. The scarcity of the literature on the subject is another limitation. The research does not cause any harm to the reputation of participation banks.
Practical implications
Adopting a single-pool system in line with the global practices will end the shift of right between pools while ensuring a fair and transparent system. In this system, the bank equities, other shareholders’ funds and participation accounts are collected and operated in a single pool. The pool profit and loss are distributed as per the shares in the pool. The profit per each participation account is distributed based on the share of each participation account in the pool and profit-sharing ratio.
Social implications
Participation banking is expected to support the real economy by means of production, leasing, merchandising based on certain religious, ethical and contractual principles. Bringing funds of conservatives, that does not go to conventional banks for avoiding of interest, in the economy is expected to provide new sources to reduce the foreign dependency for the economy and to supply a financial alternative for the conservatives who stay away from interest-based economic activities. However, if this will represent an alternative to debt-based systems, then products, contracts, business processes and legislations driven according to interest-free banking principles should be developed.
Originality/value
This study introduces and analyzes a new proposal of the profit distribution system of participation banking. A similar methodology is used in interest-free banking on a global scale, especially in Malaysia, and is compatible with the profit distribution decisions in AAOIFI’s depositor accounts. However, this methodology is considered to be new as far as participation banking is concerned. The implementation of this new methodology will eliminate several problems identified in the profit distribution system of participation banks. This research provides an academic contribution to the participation banking profit distribution system and represents a reference material on the subject.
