Technology Status and Development Trend of Modular Moving System

With the development of technology, modular independent suspension technology has been widely applied on high-movement off-road platforms in the developed world because of the characteristics of offline assembly and full-body lifting. At the same time, after the breakthrough of key techniques such as the stiffness spiral springs, the high dissipation of the shock absorbers, the lightweight of double-wishbone steering mechanism and the non-maintenance bearing, the ability to carry the off-road mobility and armor protection of the military vehicles have been significantly increased. In this case, the application of the modular independent suspension and its current state around the world was explained, that the development of this technology is of great significance to the off-road maneuvering of our military equipment was also represented in this paper.

Body lifting, flattening, and burying of Tropidurus catalanensis Gudynas & Skuk, 1983 (Squamata, Tropiduridae): Defense, thermoregulation, or both?

Lizards of the genus Tropidurus display different behaviors for thermoregulation and defense. Here, we report new displays for Tropidurus catalanensis, which helps to understand how these lizards behave. Captive individuals lifted, flattened, and buried their bodies. Flattening and upstanding the bodies allow looking larger and may discourage attacks, as well as respectively enhance and decrease the approximation and the contact of body surfaces with substrates to thermoregulate. Burying themselves into earth and sand may help lizards to avoid or escape from menaces. When we first opened the containers, the T. catalanensis were already partially covered by vermiculite, which did not allow stating if they did it in response to supposed risks of predation because perceived the movements in the room or were already buried. Tropidurus catalanensis possibly may bury themselves to avoid detection during periods of inactivity. The self-burying behavior may be useful also for thermoregulation using substrate temperatures. Tropidurus catalanensis may increase the chances of getting out safe from dangerous interactions and of effective thermoregulation by performing such behaviors. Although we discussed the behaviors on the views of defense and thermoregulation, the body lifting, the flattening, and the burying seemed have occurred in a defensive context.

Comparison of Physical and Motoric Features of Children Continuous the Sport School

Objective: The comparison of the physical and motoric features of the children continuous sport school within team sports.Method: A total of 60 male athletes from 9 to 10 years participated as volunteers in the Galatasaray Sports Club for three months in basketball and volleyball. 27 of these athletes were basketball players and 33 were volleyball players. The age, height, weight and BMI of the basketball players were 9,19 ± 1,9 years; 140,37 ± 12,1 cm 38,06 ± 1,4 kg; 18.71 ± 3.7 kg / m² and the volleyball players were 10.54 ± 1.6 years,; 145.57 ± 10.5 cm; 41,34 ± 1,4 kg; 19,22 ± 3,3 kg / m² respectively. The body mass index (BMI), which measures the height and body weight of the participants, was calculated. For the evaluation of the motoric properties, sit and reach, trunk lifting, hand grip, ball throwing, push-up, shuttle, 10 mt speed, T test for agility, was tested. The SPSS 20.0 statistical program was used in the evaluation of the data. Independent Samples T Test was performed to compare the obtained data.Findings: Significant difference was found sit and reach, body lifting and ball throwing in volleyball and was found 10 m speed in basketball (p <0,05).Conclusion: Although some motoric features give different results in children going on to basketball and volleyball sports school, it has been found that they show similar features in most cases.
