The Cu1.01Cr1.35Sn0.40Se4.0 and Cu1.01Cr0.90Sn0.80Se4.0 do not reach the saturation for the 5T magnetic field, although they possess positive Curie temperature, which is an indication of the bond frustrated material and competing ferromagnetic and antiferromagnetic components.

The weighing bucket material door could open to both inner and out side [1], in order to discharge material to memory bucket or set bin.
After weighed, the material is fed into the below memory hopper, meanwhile the weight of the material is fed into the ROM of controller and storied temporarily, and must be one-to-one correspondence with the corresponding number of memory hopper.
The feasibility of eight combination hoppers is argued by changing the material deviation.
In the material display space, each material hopper is replaced by several reaction vessels, the I/O domain of current material quality value is displayed on all hoppers, so we can easily see the quality distribution of current each hopper.

This study also deals with how to improve the fire-resistance of the high strength concrete on unstressed condition. 2.1 Technological trend related to the fire-resistance of high strength concrete A study on the spalling of concrete beams associated with the employment of spalling-mitigating material was conducted based on material test.[5] According to the study, the fiber cocktail mixed in 60MPa concrete beam results in the mitigation of spalling and peeling-off and the concrete secures the required fire-resistance duration of 180 minutes.

Characteristics of materials: Characteristics of materials used in the models and essential for the study are included in the Table 1.
Characteristics of the materials of the individual elements Flexibility module [MPa] (E) [MPa] Poisson factor (υ) [-] Subchondral layer 16500 0,3 Spongiosa layer 400 0,2 Screw (stainless steel) 200000 0,26 Fig. 5 The characteristic of the non-linear material law Contact relation between contiguous elements: Taking into account the actual relations between the implant and the bone layers, we defined a so-called Frictional contact relation, owing to which the individual surfaces can freely move on each other but they cannot penetrate into the other one and thus model the real contact relation.
Characteristics of materials The loading capacity of models with spongiosa bone matter significantly differs from that of the subchondral bone layer models.

Introduction Over the last couple of years, ecological awareness and other environmental issues have led to the development of composite materials based on renewable resources such as natural fibers as environmentally friendly and low-cost alternatives for synthetic fibers and the use of plastics based on renewable resources for the development of true biocomposites.
It is also necessary to study of flame sensitivity of these composite materials, which is desirable not only for the useful insights it can produce but also for its fire-safety importance.
