Comparison of pet dogs and cats

With the development of society, our life is becoming better and many people chose to keep a pet. For pet owners, keeping pets is wonderful. It is universally acknowledged that pets do help pet owners be happy. Generally speaking, people chose different kinds of animals as their pets. To my mind that different kinds of pets shows different characters such as cats and dogs. And comparison of cats and dogs would be shown as follows.

Undoubtedly, cats and dogs have many characters in common. Meanwhile, it is conceivable that cats and dogs can bring happiness to their owner. It is obvious that they are so fuzzy and cute that we all like them. It is believed that the existence of pet dogs and cats is of great importance in pet owners' daily life especially for some old people who live alone. Besides, pet cats and dogs need our care. Therefore, keeping pet cats and dogs could enhance the relationship between lovers to some extent.

There is no denying that cats and dogs are different. On the one hand, pet dogs have some merits that cats don't have. Some people chose to raise a dog on account of that it is easier for a dog to develop a good habit. Obviously, pet dogs are human, lovely and friendly. Many owners of pet dogs believe that the pet dog is their true friend.

On the other hand, many people like to raise cats other than dogs. It is believed that cats are pretty cute that a quantity of people prefers to play with it. In addition to this, the reason why people like pet cats is that it is easier to take care of. And this is because that it takes time to walk the dog. In addition, cats are quiet and cute whereas dogs are active.

In conclusion, both dogs and cats have merits and demerits. Dogs and cats have some characters differently for they are different species. Besides, cats and dogs have many characters in common such as growing up with us. In my personal view, it is difficult to select which kind of pet is better and both cats and dogs are our human being's good friends. It goes without saying that we should protect them and take care of them.

Facile preparation of molecularly imprinted grapheme-multi-walled carbon composite film modified electrode for rutin sensing

In this paper"facile preparation of molecularly imprinted grapheme-multi-walled carbon composite film modified electrode for rutin sensing "Dr. Lite Yang (2016) writes about a novel molecularly imprinted electrode. Molecularly imprinting is widely used in fabricating sensors, because it can enhance selectivity and sensitivity. The modified

electrode is of great importance in detecting natural compound. In this article, the netlike composite has high conductivity and electro-catalytic activity. Therefore, at the resulting modified electrode the compound could produce a sensitive anodic peak. The electrode was successfully used to detect the compound rutin in buckwheat tea and orange juice samples.

Rutin is a compound that is widely found in planers, such as in buckwheat tea, fruits and berries as well as in many Chinese herbs. It can strengthen the capillaries and inhibit platelet aggregation, making the blood thinner and improving circulation. Rutin is also well-recognized as a therapeutic medicine with the physiological functions of

anti-inflammatory, anti-tumor and anti-bacteria.
