Background and purpose: The development of pre-implantation mammalian embryos in vitro is compromised, compared with those grown in vivo. Selecting embryos with a high implantation potential is one of the most important challenges in the field of assisted reproductive technology. The aim of this study was to postulate morphometrical characteristics of good quality embryos, with comparisons be...
Background: Evaluating and identifying existing challenges of the healthcare system reform plan can help policy makers and executives address these shortcomings and achieve the goals of the plan. The purpose of the current study was to evaluate the satisfaction of health network employees with healthcare reform plan in Bushehr province. Materials and Methods: This qualitative study was conducte...
Background and objective: The most important factor for success in every organization, s its human resources. Human resources with the power of creativity, imagination, faith and commitment, have a great impact on the performance of the organization. University faculty members are the main pillars of human resources and affect the development of universities to promote academic stan...
The transition from product development towards development of product-service systems (PSS) challenges manufacturing industry today. This paper is based on a case study of a company in the aerospace industry that turned their internal product knowledge into an external service offer, which challenged established structures of the product development process. The process and challenges of the c...
Background & aim: Midwives, as a part of the healthcare team, have a remarkable role in providing health to families and societies. Midwives have a prominent role in the family physician program (FPP); therefore, the lack of proper attention to their challenges results in a decline in their efficiency and quality of care. Therefore, this study was performed to explore the midwives’ perceptions ...
Information Systems (IS) programs are facing serious challenges. Some of them are external, therefore we can mostly react to them, while others are internal to our programs and consequently we can do a lot about them. It is very important for IS academics to be aware of these challenges, the implications they have, and the strategies that can be implemented to address them. Our contention is th...
The possibility of employing internal wall as mass absorber in rectangular water storage tanks subjected to harmonic ground motion excitation is investigated in this paper. Internal walls are used in these tanks usually for service performance purposes, which could be used as mass absorber to control seismic demand on tank's exterior walls. Derivation of the response of the coupled system inclu...
AB S TRACT The effects of external anions on gating of Na channels of frog skeletal muscle were studied under voltage clamp. Anions reversibly shift the voltage dependence of peak sodium permeability and of steady state sodium inactivation towards more negative potentials in the sequence : methanesulfonate < Cl5 acetate < Br5N03 < S04 < benzenesulfonate < SCN< C104-; approximately the lyotropic...
Introduction: around the world, the science system of many countries is being transformed and changed in response to increasing social and economic need for knowledge and technology. The theory of the entrepreneurial university is one of the models proposed for reflecting the new and transformed image of the university characterized by a broader interaction between the universities and the comm...
in this paper, a schwarz-christoffel method for generating two-dimensional grids for a variety of complex internal and external flow configurations based on the numerical integration procedure of the schwarz-christoffel transformation has been developed by using mathematica, which is a general purpose symbolic-numerical-graphical mathematics software. this method is highly accurate (fifth order...
