Stress plays an important role in understanding the quality and stability of family relationships. Therefore, the aim of the present study was to investigate the effectiveness of short-term stress-based treatment training for female teachers in Kashmir.

The research method is a semi-experimental type of pre-test - post-test with a control group. The statistical population of this research consists of all women with marital incompatibility who referred to the education and training counseling center of Kashmar city in the first quarter of 2017, which number of 40 women were selected by available and voluntary sampling and divided into two experimental groups (20 people). and control (20 people) were randomly divided. To collect data, Das Ladibond and Ladibon (1995) stress scale was used. After the therapeutic intervention in the experimental group, a post-test was taken from both groups. Multivariate covariance analysis was used to analyze the data.

 The results of covariance analysis showed that solution-oriented family therapy had significant effects on the stress of female teachers (P≥0.001).

It seems that the solution-oriented approach can have an effect on the stress of female teachers; However, in order to increase the external validity of the research, it is suggested that more research be done in this direction.

Due to the need for orthopedic surgery, the mechanical behavior of the cortical bone in cyclic loading and physiological strain rate has been investigated. The emphasis is on developing a structural law that can establish the behavior during loading, unloading and reloading observed in experiments. These models will be formulated by combining rheological elements and energy principles. First, two one-dimensional models independent of the strain rate are formulated, one with one damage variable and the other with two different damage variables in tension and compression, are examined, and using laboratory data, the coefficients of each model are obtained. By comparing the simulation results and laboratory data, the necessary modifications have been made to the models. Finally, by combining the Bresler-Pister anisotropic yield criterion and the one-dimensional model independent of the rate associated with the two damage variables, the corresponding three-dimensional model was obtained. This three-dimensional model was implemented in the form of an explicit finite element method and the result showed acceptable compatibility with the simulation results of the one-dimensional model and experimental data. This three-dimensional model will be suitable for simulating complex geometries. The coefficient of determination for one-dimensional modelsRI ,RI± ,RI , RI±and  has been modified and the three-dimensional model has obtained values of 0.882174, 0.965665, 0.995508, 0.996279, and 0.984866, respectively.

Magnesium-based nanocomposites are widely used in the aerospace, automotive, and medical industries. Due to the special properties of boron nitride nanotubes, these nanotubes play an important role in strengthening nanocomposites. In this research, magnesium nanocomposites are reinforced by boron nitride nanotubes and the mechanical properties of these nanocomposites under uniaxial tensile loading in the axial direction of the nanotubes have been investigated by the molecular dynamics method by Lammps software. Also, the coefficients of the atomic potential function of magnesium atoms have been calculated using the law of composition and the data extracted by Gaussian software. The results of molecular dynamics simulations show the improvement of mechanical properties of magnesium-based metal nanocomposites due to the addition of boron nitride nanotubes. The presence of boron nitride (0,12), (0,14), (0,16) and (0,18) nanotube reinforcers as magnesium field reinforcers increased the elastic modulus by 13, 14.9, 16.2 and 17 percent. Other results of this study indicate that the elastic behavior of nanocomposites is independent of strain rate changes. Also, by performing this simulation over a wide range of temperatures, obvious changes in the mechanical properties of the nanocomposite at different temperatures have been obtained.

This research was designed to demonstrate the impact of voluntary exercise on sperm parameters including sperm count, morphology, motility, viability, testicular apoptosis, oxidative stress, and the mir-34a/SIRT1/p53 pathway in type 2 diabetic rats. 32 Wistar male rats were separated into four groups: control (C), voluntary exercise (VE), diabetic (D), and diabetic rats that performed voluntary exercise (VED).

In orthopedic surgeries, the bone drilling is one of the most important biomechanic processes that has used. ،This mechanical process is very important, sensitive and all-purpose in biomechanical engineering, because its complexity and special conditions. Bone drilling process has advanced by roboots and CNC machin entrance into the realm of orthopedic surgeries. The problematic issue during operation is the high increase in drilling process temprature which leads to the so-called thermal necrosis. It is not clear quality of enfluence of tool rotational speed and feed rate on the temprature and force responses and so it can be seen confilicts among different researcher results frequently. In this paper it is performed mathematical modeling and design of experiments on the input factors and output parameters of bone drilling. The effect of input factors and interaction of input factors have investigated. Increasing rotational speed the temperature increases where as the feed rate behavior is complex because contact duration between drill bit and bone so the increasing temperature take places because the low feed rate or increasing force and friction. In addition increasing the drill bit diameter increases the tempratures. Also the sobol sensitivity analysis method has used to investigate effect of each parameter in which rotational speed, feed rate and drill bit diameter have most effect respectiviely on temperature instantaneously. Also optimization process performed on temperature behavior, hence the minimum temprature is 37 0C when the diameter of drill bit 2. 5 mm, rotational speed 500 rpm and feed rate 30 mm/min.

One of the most important machining processes in the field of orthopedic surgeries and biomedical engineering is the drilling process. Applying excessive forces on the bone tissue, it can be caused cracking and damage bone tissue during the drilling process. In this paper, it is produced an improved analytical model based on early work done by Bono and Ni, Chandrasekharan, and Lee to predict the thrust force in the bone drilling process. In this model, the cutting action at the drill point is divided into three regions: the primary cutting lips, outer portion of the chisel edge (the secondary cutting edges), and inner portion of the chisel edge (the indentation zone). All three regions have been investigated for the cutting process by the analytical model. In order validating the model, some experiments performed on the fresh bovine bone. Feed rate and rotational speed are adapted as the effective parameter in the drilling process, The statistical model to obtain the mathematical model and provide interaction diagrams of input variables experiments, to response surface methodology and experimental investigation of bone drilling have been offered. Comparing the analytical model and experimental results show good agreement. From both analytical model and experiments, it is can conclude that with decreasing feed rate and increasing rotational speed, thrust force on the bone tissue decreases.
