Week three understanding fats and fibers There are four major fat types they are known as; monounsaturated fats‚ polyunsaturated fats‚ saturated fats‚ Tran’s fats. Saturated fat and Tran’s fat are two fats classified as bad fats. We should limit these types in our daily diets. Saturated fats are for the most part of found in red meat‚ and dairy products. Trans fats are super unhealthy‚ we should avoid eating them period. Tran’s fats are primarily found in pre mixed products such as; snack

step index fiber It is an optical fiber which has a core of constant refractive index.there are two types of step index fibers:single mode si and multi mode si fiber single mode step index fiber has only one mode of EM propagation (HE11) an has a core diameter of about 8-12 Um. and multi mode si has many mode of propagation and has a core of diameter of about 50 Um which allow many no of modes through it. single mode step index has an adv of lower inter modal dispersion as there is only

If pain is C-fiber stimulation‚ then it is necessarily true that pain is C-fiber stimulation and it could not have been otherwise in all possible worlds. Thus‚ the identity statement “Pain is C-fiber stimulation” is necessarily true. However‚ it is conceivable that there is one possible world in which pain is not C-fiber stimulation. If that is true‚

The adaptation of natural fiber composites in the consumer industry has not had the same explosive growth as with the transportation or even the construction industry. The benefits of cost savings and weight reduction that can be obtained with natural fiber composites played a significant role for the proliferation into those respective industries. But in the consumer market‚ stemming from the rise of synthetic fibers starting in the 1940’s‚ glass fiber and carbon fibers have dominated the market
