    Yemen’s Health sector has grown significantly gauged from the increasing number of hospitals, health units, health centers, beds and medical staff. Despite the country's direction towards the health sector development and improvement, Yemen ranked poorly in all central factors of health services and access.This paper aims to propose a high level telehealth model which is peculiar to Yemen in terms of its existing health services, culture, geography and ICT readiness.In achieving the aim, a series of interview and document study were conducted to access its ICT potential-infrastructure;rural communication; and available manpower and skill set. It is hoped that implementation of the framework will be able to address the issue

    A complex diophantine quadruple with the property D,(z)(z), where zinz in Z[sqrt2][sqrt {-2}], is a subset of Z[sqrt2][sqrt {-2}] of four elements such that the product of its any two distinct elements increased by zz is a perfect square in Z[sqrt2][sqrt{-2}]. In the present paper we prove that if bb is an odd integer, then there does not exist a diophantine quadruple with the property D(a+bsqrt2)(a + bsqrt{-2}). For z=a+bsqrt2z=a+bsqrt{-2}, where bb is even, we prove that there exist at least two distinct complex diophantine quadruples if aa and bb satisfy some congruence conditions

    In this paper, numerical solutions to thermally radiating Marangoni convection of dusty fluid flow along a vertical wavy surface are established. The results are obtained with the understanding that the dust particles are of uniform size and dispersed in optically thick fluid. The numerical solutions of the dimensionless transformed equations are obtained through straightforward implicit finite difference scheme. In order to analyze the influence of various controlling parameters, results are displayed in the form of rate of heat transfer, skin friction coeffcient, velocity and temperature profiles, streamlines and isotherms. It is observed that the variation in thermal radiation parameter significantly alters the corresponding particle pattern and extensively promotes the heat transfer rate

    The intent of this paper is to establish the detailed parametric study for laminar natural convection ow along a vertical wavy plate. Typical sinusoidal surface is used to elu- cidate the heat transport phenomena for the gas having variable thermophysical properties. From the present analysis, we will interrogate whether the presence of roughness element disturbs the gas ow and alter the physical characteristics associates with the wavy surface or not? The numerical solutions are obtained after converting the governing equations into a suitable coordinate system. The results are interpreted for the parameters which emerge from the temperature dependent physical properties of the gases and transverse curvature of the surface. In order to ensure the accuracy, the present numerical results are also compared with some special cases and are found in good agreement. The key observation from the present analysis is that the amplitude of wavy surface parameter, a contributes in reduction of heat transfer rate

    An analysis is performed to study the two-phase natural convection flow of nano fluid along a vertical wavy surface. The model includes equations expressing conservation of total mass, momentum and thermal energy for two-phase nano fluid. Primitive variable formulations (PVF) are used to transform the dimensionless boundary layer equations into a convenient coordinate system and the resulting equations are integrated numerically via implicit finite difference iterative scheme. The effect of controlling parameters on the dimensionless quantities such as skin friction coefficient, rate of heat transfer and rate of mass transfer is explored. It is concluded from the present analysis, that the diffusivity ratio parameter, N_A and particle-density increment number, N_B have pronounced influence on the reduction of heat transfer rate

    Higher Education Leadership and the Internationalization Imaginary: Where Personal Biography Meets the Socio-Historical

    Get PDF
    In this chapter, we explore how higher education institution (HEI) leaders perceive the relationship between their international background and their commitment to and vision for internationalization. Our 10 Canadian HEI participants thought there was a direct link between their international backgrounds and commitment to internationalization. While all spoke of the benefits of internationalization, some viewed internationalization through an ethical, socio-cultural lens whereas others privileged internationalization’s instrumental values. We point to tensions facing some leaders in reconciling their ideal visions of internationalization with neoliberal pressures facing HEIs in a global era. We demonstrate the importance of attending to the inter-relationships between broader socio-historical drivers of internationalization and the personal biographies of those charged with advancing internationalization agendas. Our findings lead us to develop a new theoretical concept, which we term the ‘internationalization imaginary’, to understand the interplay between the individual, local, national and global forces shaping internationalization in higher education

    The Impact of an Educational Program based on the Components of Emotional Intelligence according to the Golman Model in the Development of Ethical Behavior in Islamic Education

    Get PDF
    This study aimed at identifying the effect of an Islamic Educational Programme based on Emotional Intelligence on developing Ethical Behaviors of tenth grade female students in the Sultanate of Oman. The study adopted a semi-experimental model using a sample of 137 students from Muscat and Southern Batinah schools. To achieve the study aims, an Educational Program based on Emotional Intelligence and Ethical Behaviors Scale (Self-control, Honesty, Respecting others, Respecting rules) was used. The validity of the scale was measured using trustee validity and discriminate validity. Cronbach’s Alpha coefficient was used to estimate the reliability of the scale; it was 0.90 which indicates fairly high reliability. The results showed statically significant differences in regards of Self-control, Honesty, Respecting others and Respecting Rules in favor of the experimental group. In the light of the above findings, the study recommended the importance of integrating Emotional Intelligence skills into the curriculum to prevent ethical problems of teenage students. It also suggested the activation of educational strategies and classroom activities in training the students to develop their ethical behaviors
