Magnetic Properties of M-type Hexaferrites 2.1.
The structural properties of M-type hexaferrite depend on many factors like preparation methods, sintering temperature, time, chemical composition and amount of substitution etc.
Magnetic Properties of M-type Hexaferrites.
Therefore, resins which shrink a lot or harden unevenly should be avoided, and some resins also generate extreme localized heat as they set, which could affect the magnetic properties [90].

Chitin and chitosan are recommended as suitable functional materials because these natural polymers have excellent properties such as biocompatibility, biodegradability, non-toxicity, adsorption properties, etc.
The properties of chitosan are greatly affected by the process conditions that control the process of deacetylation occurs.
The material photodegradation properties were evaluated, MB photodegradation on TiO2-chitosan hybrid materials was of 91%.
The biggest advantage of ZnO is low in price, good gas sensing properties, photocatalytic activity, antibacterial activity, possibility to prepare structures with interesting optical properties, etc.
Parameters affecting the photocatalytic decolourization process, such as photocatalyst amount, solution pH, initial AR 66 concentration plays an important role in Photocatalytic activity.

Therefore, the interfacial bond strength which is dependent upon time is also a function of morphological factors such as the change in interfacial area with time, progressive mineralization of interface tissues and resulting increase of elastic modulus of an interfacial bond as well as shear strength per unit of bonded area.
Although, the addition of small amount of Al2O3 in the glass retards the deposition of apatite in SBF solution on glass surface but at the same time alumina has been introduced earlier in bioglasses also to improve their mechanical properties and long term services as implant materials [35]. 4: Discussion 4.1.

A hybrid model test is carried out and corresponding numerical simulations conducted to verify the function and mechanical properties of the designed J-lay system. 2 Structure design of the J-lay system The J-lay system is complex in structure.
The allowable stress of the structure is about 230Mpa taken 1.5 as safety factor according to the design manual of subsea structure.
Communicating with TwinCAT software PLC via OPC, MCGS realizes real time data acquisition and display and control of pipe-laying operations strictly according to the workflow. 4 Model testing system In order to verify the function and mechanical properties of the J-lay system, a model (including tower adjuster subsystem, pipe loader, travelling clamps, ELUT and framework of the tower) is developed.
Although the EMI and coating error will affect the test results, the comparison between results from Abaqus and test shows that the difference is less than 10%.

Factors affecting the %retention are the addition of a water washing step right after sulfonation to remove unbound acids and the choice of washing solvent used during catalyst recovery [32,39].
The 2k factorial design of experiment is a commonly used technique in factor screening to study the effects of factors on a response variable, and it is particularly useful when the number of factors is relatively small.
As the methanol-to-COFAD ratio increases, the concentration of COFAD in the reaction mixture decreases, thereby affecting the rate of reaction and conversion.

There is no consensus regarding the etiology of hallux valgus, and the effect of different factors: extrinsic factors like footwear, and intrinsic factors like gender, heredity, hindfoot pronation, pes planus, ligamentous laxity, first ray hypermobility, neurological disease and rheumatoid arthritis.
There is no consensus regarding the etiology of hallux valgus, extrinsic factors like footwear (high-heeled shoes) and intrinsic factors (gender, heredity, hindfoot pronation, pes planus, ligamentous laxity, first ray hypermobility, neurological disease and rheumatoid arthritis) being implied [2-5].
An important issue are the design of the orthopedic implants because are used different processing techniques of the metallic biomaterials in order to obtain various types of orthopedic implants like screws, plates, wires, pins, that could affect the metallic materials microstructure, mechanical properties and implant surface [16, 18, 19].
One of the factors which can be linked to the osteolysis is corrosion of the metal.

It has the features of high mechanical integration, electrical motor construction materials and higher efficiency of drive system components.
In the mechanical system with Multi-Degree-of-Freedom movement, a Multi-Degree-of-Freedom motor can replace two or more Single-Degree of Freedom motor, which greatly simplifies the structure of mechanical systems, reduces size and weight, and eliminates the disadvantages such as free play and friction the gear drive brought etc.
In the Multi-Degree-of-Freedom device used for driving high-speed and super speed, there are mechanical (bearing) supporting wear problems.
The function of bearing significantly affects the reliability of the motor and the utilization ratio of equipment.

Abstract: In this study, we investigate the characteristics of activated sludge pretreated with microwave irradiation and the factors influencing the microwave effects.
The microwave output power was one of the most important factors for improving the dewatering of activated sludge when all other parameters of activated sludge and microwave frequency were held constant.
However, reducing sludge’ water percent content below 80% when the activated sludge has been conditioned by commonly used conditioners is more difficult than by mechanical means [8].
However, longer exposure times than 40s adversely affect the sludge settling ability as shown in Figure 2.
(4) Lastly, the power of the microwave source is the most important factor when the microwave frequency and the properties of sludge are held constant.
