  The purpose of this study is to provide a rich insight into the factors affecting the growth of teams and startups in Academic Development Centers. In this study, the factors affecting the growth of teams and startups were investigated using the system dynamics approach. At first, after reviewing the theoretical literature and the experts’ opinions, Variables affecting the growth of teams and startups were indentified and causal relationships among these variables were depicted. Then, the mathematical relations among these variables were determined and, accordingly, the study system was simulated at growth centre of technician and knowledge based units at Imam Hussein comprehensive university during the period 2016 to 2066. After designing the cause and effect diagrams, six scenarios for the growth of teams and startups were defined, which are: The growth center's share of the profits of successful companies, The effect of interaction with successful companies in promoting the level of entrepreneurial culture, The effect of effective communication with successful companies in attracting financial support for technology units, The effect of changes in the number of clients to enter the center on the system, Admission control policy and The effect of legal protections of technology units on the system. Of the six simulated scenarios, the fifth scenario has the greatest impact on the growth of teams and startups in Academic Development Centers. Therefore, the policy of maintaining the quality of services through controlling the amount of technology units entering the growth centers can be considered an effective and important policy.

  An external skeletal fixator is an orthopedic method for treating open or closed fractures of long tubular bones, joint stiffness, bone lengthening, and congenital malformations. An external skeletal fixator is a device that is installed outside the organ and inserts pins into the fracture to fix it and adjust the position of the pin. They are connected to the frame and secured with bolts and nuts. Fixtures have changed significantly in appearance and biomechanics over time, but the principle and function remain the same. These fixtures consist of pins or thin stainless steel wires that penetrate the skin and reach the bone. This way the broken part is fixed in the right direction. Depending on the body geometry and shape, these external skeletal fixators are available in different types such as linear, circular, and hybrid fixators. The simplest and most common type of external skeletal fixator is the linear fixator. The use of an external fixator has several advantages over other fixation methods such as stabilization of the fracture at some distance from the injury site, no need for a cast, ease of patient movement, and minimal involvement of the joint. Premature loosening of the pin is the most common complication causing pain, inflammation, and discharge from the pin tract. Although these fixators are versatile and effective treatment models, they require careful maintenance during treatment. Before deciding to use an external fixator, the patient's and pet's owner's ability to comply with postoperative care instructions should be considered. This article reviews the types of external fixators, postoperative care, and their complications. Manuscript profile
