The low-temperature sinterability of TiO2-CuO systems was investigated using a solid solution of SnO2. Sample powders were prepared through conventional ball milling of mixed raw powders. With the SnO2 content, the compositions of the samples were Ti1-xSnxO2-CuO(2 wt.%) in the range of x  0.08. Compared with the samples without SnO2 addition, the densification was enhanced when the samples were sintered at 900oC. The dominant mass transport mechanism seemed to be grain-boundary diffusion during heat treatment at 900oC, where active grain-boundary diffusion was responsible for the improved densification. The rapid grain growth featured by activated sintering was also obstructed with the addition of SnO2. This suggested that both CuO as an activator and SnO2 dopant synergistically reduced the sintering temperature of TiO2.

Many people know the benefits of massage for people, especially if they have had an injury. It can also be a very relaxing experience. It the same way, dogs can benefit from pet massages. The owners can choose to do the massage thyself. Some of the benefits of massaging dogs were included to help him recover after an injury or strain, to be calm an excitable dog, to enhance blood circulation and other body functions, to restore and maintain muscle tone, also taken a chance to bond with dogs, to increase trust, and to provide relaxed effects. We are aimed to provide the available knowledges about the health-beneficial functional massage techniques for the companion dogs through literature review. As the results, we reviewed the massage techniques like as stroking, effleurage, wringing and kneading etc. Massages can improve a number of physical body functions like as blood circulation, gastrointestinal functions, relaxing, muscular stretching, immune activation, human animal bonds in dogs. Also, dog massages could induce the decrease of stress, depression and the palpation of the disease of dogs.
