The Body freedom flutter phenomenon is one of the aeroelastic instabilities that occurs due to the coupling of the aeroelastic bending mode of the wing with the short-period mode in the flight dynamics of the aircraft. By using the aeroservoelastic model and applying closed loop control, this phenomenon can be suppressed in the operating conditions of the aircraft and the velocity of this event can be increased. The simplest model aircraft capable of displaying this instability includes the flexible wing and the planar flight dynamics model. For this purpose, the wing structure is modeled using the Euler-Bernoulli beam and, the theory of minimum variable state is used to model unstable aerodynamics to make the conditions suitable for modeling the system in state space. In the control section, the elevator is used as the control surface and LQR theory with Kalman filter is used to Body freedom flutter suppression. Finally, the effect of adding a closed loop control to increase the Body freedom flutter velocity and the limitations of this work are studied.

Introduction. The study of gross anatomy has always been confronted with limitations including deterioration, bad odor of cadaver and fixative solutions. one of the modern preservation techniques is plastination. In this project a whole Body was made by plastination technique.Methods. This study was carried out on a fresh human Body after fixation of the cadaver. It was dissected carefully after 6 months. It was then dehydrated and defated in cold acetone (-25˚6) for 2 weeks and warm (35-40˚c) acetone for 4 weeks. finally it was impregnated by polymer under pressure of vaccum. Results. The plastinated specimens found to be immune from infection, deterioration and flexible without bad odor and showing natural color.Discussion. Plastination is a modern techinque that has many advantages to formaldehyde fixation especially for our country with limited source of Body donation. Plastinated specimens can be unique material for teaching and can play a key role in solving our problem of cadaver shortage.  

An unknown 55 years old man with loss of consciousness, bradypnea, cyanosis and miotic pupil was referred to hospital from a bus terminal. Neurological examination revealed no lateralized sign and acrocyanosis was positive. A short time after administration of hypertonic glucose and naloxone, he had seizure, hypotension and apnea, therefore, he underwent intubation and mechanical ventilation. Primary laboratory examinations revealed respiratory acidosis and hypoxemia. After brain CT scanning and other lab tests, he received naloxone again and showed more consciousness. Since the man was on suspicion of Body packing, plain abdomen X-ray was done and the existence of several packs was confirmed. Treatment by polyethylene glycol 2 lit/h and naloxone and serial activated charcoal started and finally, the patient excreted the packets and was then discharged with good condition.

The object of this research was to study the of professional and amateur male Body builders’ Body dissatisfaction and mental Health. For this reason, 97 Body builders (46 professional and 51 unprofessional) of Tehran (age range of 21 to 34 years) were selected randomly and fulfill the General Mental Health and Body Dissatisfaction questionnaire. Results showed that from the point of sub measures of physical sign, anxiety and depression, there was not a significant difference between two groups while in the social performance dimension, performance of unprofessional Body builders was significantly better (p=0.001). Body mass index mean and idealistic Body mass index were not equal in two groups. The amount of dissatisfaction from weight and form of Body was not equivalent in two groups and the direction of this disorder was the same in them. In general, because of Body mass index mean and idealistic Body mass index were different, there was dissatisfaction from Body condition between both groups of professional and unprofessional Body builders.
