In-situ experiments conducted within a transmission electron microscope provide the operator a unique opportunity to directly observe microstructural phenomena, such as phase transformations and dislocation-precipitate interactions, “as they happen”. However, in-situ experiments usually require a tremendous amount of experimental preparation beforehand, as well as, during the actual experiment. In most cases the researcher must operate and control several pieces of equipment simultaneously. For example, in in-situ deformation experiments, the researcher may have to not only operate the TEM, but also control the straining holder and possibly some recording system such as a video tape machine. When it comes to in-situ fatigue deformation, the experiments became even more complicated with having to control numerous loading cycles while following the slow crack growth. In this paper we will describe a new method for conducting in-situ fatigue experiments using a camputer-controlled tensile straining holder.The tensile straining holder used with computer-control system was manufactured by Philips for the Philips 300 series microscopes. It was necessary to modify the specimen stage area of this holder to work in the Philips 400 series microscopes because the distance between the optic axis and holder airlock is different than in the Philips 300 series microscopes. However, the program and interfacing can easily be modified to work with any goniometer type straining holder which uses a penrmanent magnet motor.

Background: Self-efficacy is the basis for improved self-care in diabetic patients, and self-care is the most important strategy to control diabetes. Therefore, it is important to choose an appropriate educational method to provide patients information to achieve these goals. Objectives: This study aimed to compare the impacts of teach back and video tape education methods on self-efficacy and self-care abilities of patients with type 2 diabetes. Methods: In this semi-experimental controlled study, 105 patients with type 2 diabetes were randomly divided into the three groups of teach back, video tape training, and control. The data were collected using Orem’s nursing assessment form and two researcher-made questionnaires of self-care and self-efficacy. In the teach back group, based on the extent of self-care disability in the areas of physical activity, foot care, and glycemic control, educational sessions were held for each patient individually. In the video tape group, three films were shown in those areas for patients. The control group received no intervention. Questionnaires were recompleted seven days and one and three months after the intervention through interviews. Data were analyzed using SPSS version 16. Results: The mean total score of self-care in the teach back group was significantly higher seven days and one and three months after the intervention (P < 0.00). The mean scores of self-care and self-efficacy in the teach back group (before the intervention and seven days and one and three months after the intervention) significantly increased compared to the mean variation of scores in the video tape and control groups (P < 0.001). Conclusions: Applying the teach back method is more effective than the video tape method, and it is suggested that more extensive studies be conducted to promote self-care and self-efficacy in these patients.
